                         the Policy.

                       - The Variable Account is divided into 29 Sub-Accounts,

                       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.
 
                           Because they are assessed at the fund level, you will
                       indirectly bear the fees and expenses of the Funds you
                       select. The table shown in Appendix B illustrates 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. The data regarding the Funds' fees and
                       expenses were provided by the Funds and we have not
                       independently verified it.
 
                       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 must, at
 tax-law compliance        all times, satisfy one of two legal standards for it
 tests. You select     to qualify as life insurance and thus be entitled to
 which applies to      receive favorable tax treatment under applicable federal
 your Policy.          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 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
                       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
 as such in your             Policy, or

                           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 VIP Money
                       Market Portfolio 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
 amount of your            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
                       unscheduled payments. You may change your planned payment
                       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.

                           You may change the allocation of future Net Premium

                       have a properly completed telephone authorization form

                       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

                       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.

                       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.

                           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

                           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--
 
                           - your Policy's Specified Face Amount, or
 
                           - the Account Value multiplied by the applicable
                             Death Benefit Percentage.
 
                           OPTION B--SPECIFIED FACE AMOUNT PLUS ACCOUNT
                       VALUE.  Under this option, the Base Death Benefit is THE
                       GREATER OF--
 
                           - the Specified Face Amount plus the Account Value,
                             or
 
                           - 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

                           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 increases in

                           - 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

                       equal to the amount of the policy loan from the
                       Sub-Accounts to the Loan Account on the date the policy
                       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.

                       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 premium
 varies based on the       payment up to an amount of Target Premium specified
 Specified Face        in your Policy and a 2.25% sales load on premiums paid
 Amount and the        in excess of TARGET PREMIUM for each of the first seven
 insured's Issue Age   Policy Years. Sales load rates are guaranteed not to
 and sex.              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.
 
                           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

<PAGE>
                       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 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 substan-
                       dard 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,

<PAGE>
                           - 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

                       Value will be recalculated from the Issue Date using the

                           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

                       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
                       Benefit over 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.

                       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 and

 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.

                             unmanaged securities widely regarded by investors
                             as representative of the securities markets in

                           Unmanaged indices may assume the reinvestment of

                       administrative and management costs and expenses.

                                            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,
                       disregard voting instructions if the instructions require
                       shares to be voted to cause a change in the
                       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
                       disregard voting instructions in favor of any change in
                       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.

                                      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
 
                        27                            SUN LIFE CORPORATE VUL-SM-
<PAGE>
                       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 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.

- ------------------------
 
(1) A portion of the brokerage commissions that certain funds pay was used to
    reduce funds expenses. In addition, certain funds have entered into
    arrangements with their custodian and transfer agent whereby interest earned
    on uninvested cash balances was used to reduce custodian and transfer agent
    expenses. Including these reductions, the total operating expenses presented
    in the table would have been .56% for VIP Equity-Income Portfolio, .67% for
    VIP Growth Portfolio and .71% for VIP II Contrafund Portfolio.
 
(2) FMR agreed to reimburse a portion of VIP II Index 500 Portfolio's expenses
    during the period. Without this reimbursement, the fund's management fee,
    other expenses and total expenses would have been .28%, .15% and .43%
    respectively.
 
(3) NeubergerBerman 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" includes all other expenses of the
    Portfolio and its corresponding Series.
 
(4) Expenses reflect expense reimbursement NBMI has undertaken to reimburse the
    Mid-Cap Growth Portfolio for 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, 1997 was estimated to be 1.25% for the Mid-Cap Growth Portfolio. These
    expense reimbursement policies 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. The
    Mid-Cap Growth Portfolio commenced operations on November 3, 1997;
    therefore, the expense figures for the Portfolio are estimated.
 
(5) This information reflects current fees and expenses, restated to reflect an
    agreement by Morgan Guaranty Trust Company of New York, an affiliate of J.P.
    Morgan Investment Management Inc., to reimburse the Fund to the extent
    certain expenses exceed in any fiscal year 0.75%, 0.90% and 1.15% of the
    average daily net assets of 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 1.91% for
    the J.P. Morgan Bond Portfolio, 2.31% for the J.P. Morgan Equity Portfolio
    and 3.81% for the J.P. Morgan Small Company Portfolio.
 
(6) Management fees and total operating expenses have been restated to reflect
    the management fee schedule approved by shareholders and effective May 1,
    1997. See fund prospectus for details. Actual management fees and total fund
    operating expenses during 1997 were lower.

              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 0.75%
for the first 10 Policy Years and 0.35% 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
0.7579% 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 0.7579%, 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.
 
    The gross annual rates of investment return of 0%, 6% and 12% correspond to
net annual rates of -1.50%, 4.46%, and 10.41%, respectively, during the first 10
Policy Years and -1.10%, 4.88%, and 10.85%, respectively, thereafter taking into
account the current Daily Risk Percentage and the assumed 0.7579%
 
                                      C-1
<PAGE>
charge for the Funds' advisory fees and operating expenses; and -1.64%, 4.30%
and 10.25%, 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

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

                             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.

                     SUN LIFE ASSURANCE COMPANY OF CANADA (U.S.)

                           DESCRIPTION OF ISSUANCE, TRANSFER
                             AND REDEMPTION PROCEDURES FOR
                    FLEXIBLE PREMIUM VARIABLE LIFE INSURANCE POLICIES
                          Pursuant to Rule *6e-3(T) (b) (12) (iii)


This document sets forth the administrative procedures that will be followed 
by Sun Life Assurance Company of Canada (U.S.), ("Sun Life" or the 
"Company"), in connection with the issuance of a Flexible Premium Variable 
Life Insurance Policy, (the "Policy"), the transfer of assets held 
thereunder, and the redemption by Owners of their interests in such Policy.

I.  PROCEDURES RELATING TO ISSUANCE AND PURCHASE OF POLICIES

A.  Application, Underwriting and Initial Premium Processing

To purchase a Policy, an application must be submitted to our Principal 
Office so that we may follow certain underwriting procedures designed to 
determine the insurability of the proposed Insured.  We offer the Policy on a 
regular (medical) underwriting, simplified underwriting, and guaranteed issue 
basis (each such basis is referred to as an underwriting Class).  The 
proposed Insured generally must be less than 81 years old for medical issue, 
76 years old for simplified issue, and 71 years old for guaranteed issue 
underwriting classes.  Medical and simplified issue policies may require 
medical exams and further information before the proposed application is 
approved.  Availability of guaranteed issue policies must be pre-approved 
based on information  the Owner provides on a master application along with 
specific requirements which must be met by all members of the group of 
proposed Insureds.  Proposed Insureds must be acceptable risks based on our 
underwriting limits and standards.  A policy cannot be issued until the 
underwriting process has been completed to our satisfaction and we reserve 
the right to reject an application that does not meet our underwriting 
requirements or to "rate" an insured as a substandard risk, which will result 
in the charging of increased Monthly Cost of Insurance charges and/or flat 
extra charges.

The applicant must specify certain information in the application including 
the Specified Face Amount, the APB Rider Face Amount, the death benefit 
compliance test and the death benefit option.

The Specified Face Amount must not be below the Minimum Specified Face Amount 
which is generally $5,000.  The Policy can be issued with an APB Rider, which 
provides additional life insurance coverage, annually renewable to Attained 
Age 100, on the life of the Insured.  The sum of the Specified Face Amount 
and the APB Rider Face Amount, the Total Face Amount, must not be below the 
Minimum Total Face Amount which is generally $50,000.

The Policy must satisfy either of two death benefit compliance tests in order 
to qualify as life insurance under Section 7702 of the Internal Revenue Code: 
the Cash Value Accumulation Test or the Guideline Premium Test.  Each test 
effectively requires that the Policy's Death Benefit must always be equal to 
or greater than the Account Value multiplied by a certain percentage (the 
"Death Benefit Percentage").  Thus, the Policy has been structured so that 
the Base Death Benefit may increase above the Specified Face Amount in order 
to comply with the applicable test.  The death benefit compliance test may 
not be changed.

The Policy provides the following two death benefit options for determining 
the Base Death Benefit:

Option A - Specified Face Amount.  The Base Death Benefit is the greater of 
the Specified Face Amount, or the Account Value multiplied by the applicable 
Death Benefit Percentage.

Option B - Specified Face Amount Plus Account Value.  The Base Death Benefit 
is the greater of the 

<PAGE>

Specified Face Amount plus the Account Value, or the Account Value multiplied 
by the applicable Death Benefit Percentage.   Option B is not available if 
the death benefit compliance test is the Cash Value Accumulation Test.

Pending approval of the application, any initial Premium will be held in our 
General Account without interest.  However, we may credit interest on these 
amounts on certain group cases.  Upon approval of the application, the Policy 
on the life of the Insured will be issued to the Owner.  The Minimum Premium 
is due and payable as of the Issue Date.  The Effective Date of Coverage for 
the Policy, which initially is the Investment Start Date, will be the later 
of the Issue Date, the date we approve the application for the Policy, or the 
date a premium is paid equal to or in excess of the Minimum Premium.  If an 
application is not approved, any Premium payment will be returned promptly.

Net premium is first allocated to the Policy to the separate account on the 
Investment Start Date.  During the Free Look Period, the Company will 
allocate net premiums received to the sub-account of the Sun Life Assurance 
Company of Canada (U.S.) Variable Account G (the "Separate Account") that 
invests in the Money Market Fund of Fidelity.  Upon expiration of this 
period, the account value in that sub-account will be transferred to the 
sub-accounts of the Separate Account in accordance with the Owner's 
allocation instructions.  Where state law does not require a refund of 
premiums paid when a Policy is returned under the right to examine Policy, 
initial net premiums received under the Policy will be allocated in 
accordance with the allocation specified by the Owner.

B.  Premium Payments

Premiums for the Policies will not be the same for all owners of Policies.  
An initial premium, together with a completed application satisfactory to the 
Company, must be received by the Company before a Policy will be issued. The 
Company requires that the initial premium for a Policy must be at least equal 
to the Minimum Premium for the Policy.   The Minimum Premium is the amount 
specified for each Policy based on the requested Total Face Amount, issue 
age, sex and class of the Policy.

All Premium payments are payable to us, and should be mailed to our Principal 
Office.  The Owner is not required to make Premium payments according to a 
fixed schedule, but he or she 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 semi-annual.  We will send reminder 
notices for the planned periodic Premium at the beginning of each billing 
period.  However, the Owner is not required to pay the planned periodic 
Premium; he or she may increase or decrease Premium payments, subject to our 
limits, and  may skip a planned payment or make unscheduled payments.  The 
Owner may change the planned payment schedule or the billing period, subject 
to our approval.  Depending on the investment performance of the Sub-Accounts 
selected, the planned periodic Premium may not be sufficient to keep the 
Policy in force, and the Owner may need to change the planned payment 
schedule or make additional payments in order to prevent termination of the 
Policy.

The Company reserves 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 a Policy in force.  We reserve the right not to accept a 
Premium payment that causes the Base Death Benefit to increase by an amount 
that exceeds the Premium received.  Evidence of insurability satisfactory to 
us may be required before we accept such a Premium.

If the death benefit compliance test  specified is the Guideline Premium 
Test, we will not accept Premium payments that would cause the Policy to fail 
to qualify as life insurance under that test.  The maximum Premium limit for 
each year is the largest Premium that can be paid such that the sum of all 
Premiums paid will not exceed the limitations referred to in Section 7702 of 
the Internal Revenue Code, or any successor provision.  Maximum Premium 
limits for each year will be shown in an annual report.  If a Premium 

                                    -2-
<PAGE>

payment is made in excess of these limits, we will accept only that portion 
of the Premium within those limits, and will refund the remainder.  No such 
maximum Premium limitations apply under the Cash Value Accumulation Test. 

At the time a Premium is received that would cause the Policy to become a 
Modified Endowment Contract, the Company will so notify the Owner and will 
not credit the Premium unless it has received specific instructions from the 
Owner to do so.  If such instructions are not received within 24 hours of 
notification to the Owner, the Premium will be immediately returned.

A Policy will remain in force so long as the account value less Policy Debt 
is sufficient to pay the Policy  deductions.  Thus, the amount of a premium, 
if any, that must be paid to keep the Policy in force depends upon the 
account value of the Policy, which in turn depends on such factors as the 
investment experience and the monthly cost of insurance, the monthly expense 
charge, and the daily risk percentage deduction.  The cost of insurance rate 
utilized in computing the cost of insurance will not be the same for each 
insured.  The chief reason is that the principle of pooling and distribution 
of mortality risks is based on the assumption that each insured incurs an 
insurance rate commensurate with his or her mortality risk which is 
actuarially determined based on such factors as attained age, sex (except 
under unisex policies), and class.  Accordingly, while not all insureds will 
be subject to the same cost of insurance rate, there will be a single rate 
for all insureds in a given actuarial category.

Current cost of insurance rates will be determined by the Company based upon 
expectations of future experience with respect to mortality, persistency, 
interest rates, expenses and taxes.  The cost of insurance rates are 
guaranteed not to exceed rates set based on the 1980 CSO Mortality Tables.  
The Policies will be offered and sold pursuant to established mortality 
structure and underwriting standards and in accordance with state insurance 
laws.

II.  REDEMPTION PROCEDURES:  SURRENDER AND RELATED TRANSACTIONS

Set forth below is a summary of the principal Policy provisions and 
administrative procedures which might be deemed to constitute, either 
directly or indirectly, a redemption transaction.  The summary shows that 
because of the insurance nature of the policies, the procedures involved 
necessarily differ in certain significant respects from the redemption 
procedures for mutual funds and contractual plans.

A.  Surrenders and Partial Surrenders

The Owner may surrender this Policy for the Cash Surrender Value at any time 
by sending a written request to the Company.  The amount available for 
surrender is the Cash Surrender Value at the end of the valuation period 
during which the surrender request is received.  The Cash Surrender Value is 
the Account Value, decreased by the balance of any outstanding Policy Debt, 
increased by the Sales Load Refund at Surrender, if any.  Coverage under a 
Policy will terminate as of the date of surrender.  

The Owner may make a Partial Surrender of this Policy once each Policy Year 
after the first Policy Year by written request to the Service Center.  The 
maximum amount of any Partial Surrender is the Account Value decreased by the 
balance of any outstanding Policy Debt.   Unless the Owner provides evidence 
satisfactory to the Company that the Insured is still an acceptable risk 
based on our underwriting limits and standards, the Total Face Amount will be 
reduced to the extent necessary so that the Death Benefit less the Account 
Value immediately after the Partial Surrender, does not exceed the Death 
Benefit less the Account Value immediately before the Partial Surrender.

If the Owner provides such evidence, then he or she will have the option of 
keeping the Death Benefit equal to what it was immediately prior to the 
Partial Surrender.  The Specified Face Amount remaining in force after the 
Partial Surrender must be no lower than the minimum Specified Face Amount 
which is generally $5000.  A Partial Surrender may not decrease the Policy's 
Total Face Amount to an amount less 

                                    -3-

<PAGE>

than the minimum Total Face Amount which is generally $50,000.  

The Owner may allocate the Partial Surrender among the Sub-Accounts of the 
Variable Account.  If the allocation is not specified, then the Partial 
Surrender will be allocated 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.

Amounts payable from the Separate Account upon surrender or partial surrender 
will ordinarily be paid within seven days of receipt of the written request.

B.  Changes in Face Amount

After the end of the first Policy Year, the Owner may change the Specified 
Face Amount and, if it is part of the Policy, the APB Rider Face Amount.  
Unless otherwise specified, a change in the Policy's Total Face Amount will 
first be applied, to the extent possible, to the APB Rider Face Amount.  The 
Owner must send a request for a change to our Service Center, in writing.  
The Effective Date of Coverage for changes is:

        -  for any increase in coverage, the Monthly Anniversary Day that falls 
           on or next follows the date we approve the supplemental application 
           for such increase, and

        -  for any decrease in coverage, the Monthly Anniversary Day that falls 
           on or next follows the date we receive your request.

The Specified Face Amount may not decrease to less than the minimum Specified 
Face Amount.  A decrease in Specified Face Amount or APB Rider Face Amount 
may not decrease the  Policy's Total Face Amount to an amount less than the 
minimum Total Face Amount.   A decrease in face amount will be applied to the 
initial face amount and to each increase in face amount in the following 
order:

        -  first, to the most recent increase;

        -  second, to the next most recent increases in reverse chronological 
           order; and

        -  finally, to the initial face amount.

An increase in the face amount is subject to our underwriting rules in effect 
at the time of the increase.  The Owner may be required to submit evidence of 
the Insured's insurability satisfactory to us. 

C.  Change in Death Benefit Option

If the death benefit compliance test  chosen is the Guideline Premium Test, 
then the death benefit option may be changed either from Option A to Option 
B, or from Option B to Option A.  If the death benefit compliance test chosen 
is the Cash Value Accumulation Test, only Option A is available, and the 
death benefit option may not be changed.  Changes in the death benefit option 
are subject to our underwriting rules in effect at the time of 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 the request.

If the death benefit option change is from Option B to Option A, the 
Specified Face Amount will be increased by the Account Value.  If the death 
benefit option change is from Option A to Option B, the Specified Face Amount 
will be reduced 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 in 
death benefit option will affect 

                                    -4-
<PAGE>

the determination of the Base Death Benefit from that point on.


D.  Benefit Claims

While the Policy remains in force, the Company will pay a death benefit to 
the named beneficiary in accordance with the designated death benefit option 
within seven days after receipt in its home office of due proof of death of 
the insured.  Payment of death benefits may be postponed under certain 
circumstances, such as the New York Stock Exchange being closed for reasons 
other than customary weekend and holiday closings.

The amount of the death benefit is determined at the end of the valuation 
period during which the insured dies.  The amount of the death benefit will 
never be less than the Total Face Amount of the Policy.  The amount paid, the 
Policy Proceeds, equals the amount of the Base Death Benefit decreased by the 
amount of any outstanding Policy Debt, and increased by the amounts payable 
under any APB Rider Death Benefit and any other supplemental benefits.

The amount of coverage under the APB Rider, the APB Rider Death Benefit, is 
initially the APB Rider Face Amount that is specified in the application.  
Subsequently, the amount of the APB Rider Death Benefit is adjusted 
automatically by the Company; if the Base Death Benefit under the Policy 
exceeds the Specified Face Amount (or for death benefit Option B, the 
Specified Face Amount plus Account Value) as a result of an increase in 
Account Value, the APB Rider Death Benefit will be reduced by an equivalent 
amount, under the formula set forth below.

The APB Rider Death Benefit is the greater of zero or the result of (a) less 
(b) where:

        (a)  is the APB Rider Face Amount, and

        (b)  is the excess, if any, of the Base Death Benefit over

             - the Specified Face Amount for death benefit Option A policies, or

             - the Specified Face Amount plus the Account Value for death 
               benefit Option B policies.

If the insured is living on the date of maturity (the Policy Anniversary on 
which the insured reaches attained age 100), the Company will pay in a lump 
sum the cash surrender value of the Policy.

E.  Policy Loans

The Owner may request a Policy loan of up to 90% of the Account Value, 
decreased by the balance of any outstanding Policy Debt on the date the 
Policy loan is made.  Any amount due to an Owner under a loan ordinarily will 
be paid within seven days after the Company receives a loan request at its 
home office, although payments may be postponed under certain circumstances.

Account Value equal to the amount of the Policy loan will be transferred from 
the Sub-Accounts to the Loan Account as security for the loan on the date the 
Policy loan is made.  The Owner may allocate the Policy loan among the 
Sub-Accounts for this transfer.  If the allocation is not specified, then the 
Policy loan will be allocated 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.  Account value 
transferred to the loan account will earn interest at an annual rate of 4%.

                                    -5-

<PAGE>

Interest on the Policy loan will accrue daily at the Policy loan interest 
rate of 5% in Policy Years one through ten and 4.25% thereafter.  This 
interest shall 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 the Owner will be credited to the Policy as Premium 
unless we have received written notice, in form satisfactory to us, that the 
funds are for loan repayment. 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.  The Owner may allocate the loan repayment among the 
Sub-Accounts.  If the allocation is not specified, then the loan repayment 
will be allocated among the Sub-Accounts in the same proportion that the 
Account Value of each Sub-Account bears to the total Account Value less the 
Loan Account immediately prior to the loan repayment.

III TRANSFERS

Subject to the Company's rules as they may exist from time to time and to any 
limits that may be imposed by the Funds, including those set forth in the 
Policy, the Owner may at any time transfer to another Sub-Account all or a 
portion of the Account Value allocated to a Sub-Account. 

All requests for transfers must be made to the Service Center.  The Company 
will make transfers pursuant to a valid written or telephone request received 
by the Service Center.  Telephone requests will be honored only if the 
Company has a properly completed telephone authorization form for the Owner 
on file.  The Company and its agents and affiliates will not be responsible 
for losses resulting from acting upon telephone requests reasonably believed 
to be genuine.  The Company will use reasonable procedures to confirm that 
instructions communicated by telephone are genuine.  The procedures followed  
for transactions initiated by telephone include requirements that the Owner 
identify himself or herself by name and identify a personal identification 
number.  For additional protection, all changes in allocation percentages by 
telephone may be recorded.

Transfers may be requested by indicating the transfer of either a specified 
dollar amount or a specified percentage of the Sub-Account's value from which 
the transfer will be made.  If a transfer is based on a specified percentage 
of the Sub-Account's value, that percentage will be converted into a request 
for the transfer of a specified dollar amount based on application of the 
specified percentage to the Sub-Account's value at the time the request is 
received.

These transfer privileges are subject to the Company's consent.  The Company 
reserves the right to impose limitations on transfers, including, but not 
limited to:  (1) the minimum amount that may be transferred; and (2) the 
minimum amount that may remain in a Sub-Account following a transfer from 
that Sub-Account.  In addition, transfer privileges are subject to any 
restrictions that may be imposed by the Funds.

IV.  REFUNDS

A.   Free Look Period

The Policy has a "Right to Return" provision, which gives  certain 
cancellation rights.  If the Owner is not satisfied with the Policy, it may 
be returned by delivering or mailing it to our Principal Office or to the 
agent from whom the Policy was purchased within 20 days from the date of 
receipt (unless a different period is applicable under state law) or within 
45 days after the application is signed, whichever period ends later (the 
"Free Look Period").

                                    -6-
<PAGE>

A Policy returned under this provision will be deemed void from the 
beginning.  The Owner will receive a refund equal to the sum of (1) the 
difference between any Premium payments made, including fees and charges, and 
the amounts allocated to the Variable Account, (2) the value of the amounts 
allocated to the Variable Account on the date the cancellation request is 
received by the Company or its agent from whom the Policy was purchased, and 
(3) any fees or charges imposed on amounts allocated to the Variable Account. 

However, certain states provide for a full refund of premiums.  If the 
Policy provides for a full refund under its "Right to Return" provision, the 
Owner will receive a refund of all Premium payments made, with no adjustment 
for investment experience.

B.  Conversion Privilege

The Owner may convert the Policy into a flexible premium universal life 
policy offered by 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 the Company's approval and will be restricted to those 
policies that offer the same Class and rating as the Policy.  The new policy 
will be issued without evidence with the same Class and rating as the Policy. 
The conversion provision does not apply to the APB Rider, if any, or to any 
supplemental benefits that may be attached to the Policy.

C.  Suicide

In most states, if the Insured, whether sane or insane, commits suicide within 
two years after the Issue Date,  the Company will not pay any part of the 
Policy Proceeds.  The Company will refund the Premiums paid, less the amount 
of any Policy Debt and any Partial Surrenders.

D.  Incontestability Clause

All statements made in the Application or in a supplemental application are 
representations and not warranties.  The Company  relied 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.  
No statement can be used by the Company in defense of a claim unless the 
statement was made in the application or in a supplemental application.  In 
the absence of fraud, after the Policy has been in force during the lifetime 
of the Insured for a period of two years from its Issue Date, the Company 
cannot contest it except for non-payment of Premiums in accordance with the 
Insufficient Value provision.  However, any increase in the Total Face Amount 
which is effective after the Issue Date will be incontestable only after such 
increase has been in force during the lifetime of the Insured for two years 
from the effective date of such increase.  Any increase in Base Death Benefit 
over 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.

E.  Misstatement of Age or Sex  

If the age or (in the case of a Non-Unisex Policy) sex of the Insured is 
stated incorrectly in the Application, the amounts payable by the Company 
will be adjusted as follows:

     -  Misstatement discovered at death: The Death Benefit will be that which 
        would be purchased by the most recently charged Monthly Cost of 
        Insurance rate for the correct age or (for a Non-Unisex Policy) 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 (for a 

                                    -7-
<PAGE>

        Non-Unisex Policy) sex.

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.  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
