                          COLONIAL SEPARATE ACCOUNT B
 
          INDIVIDUAL FLEXIBLE PREMIUM VARIABLE LIFE INSURANCE POLICY
 
                                   ISSUED BY
 
                     CHUBB COLONIAL LIFE INSURANCE COMPANY
                               ONE GRANITE PLACE
                         CONCORD, NEW HAMPSHIRE 03301
                                (603) 226-5000
 The Flexible Premium Variable Life Insurance Policy ("Policy") currently
offered by Chubb Colonial Life Insurance Company ("Chubb Colonial") (formerly
"The Colonial Life Insurance Company of America") and described in this
Prospectus is designed to provide a policyowner with both lifetime insurance
protection and maximum flexibility in connection with premium payments and
death benefits. Although each Policy contains a schedule of intended premium
payments ("Planned Periodic Premiums"), and an intended frequency of premium
payments ("Premium Frequency"), a policyowner may, subject to certain
restrictions, vary the frequency and amount of the premium payments and
increase or decrease the level of life insurance benefits payable under the
Policy. This flexibility allows a policyowner to provide for changing
insurance needs within the framework of a single insurance policy. Unlike
traditional lifetime insurance protection, the policyowner participates in the
investment experience of Colonial Separate Account B ("Separate Account B").
Accumulation value under the Policy will increase with positive investment
experience and decrease with negative investment experience. Accumulation
value in Separate Account B is not guaranteed and could decline to zero.

 The Policy provides for a death benefit payable at the Insured's death. If
net premiums are allocated to Separate Account B, the amount of the death
benefit may reflect the investment experience of the chosen division of
Separate Account B, as well as the frequency and amount of premiums, any
withdrawals of cash value ("withdrawal"), and the charges assessed in
connection with the Policy. As long as the Policy remains in force, the death
benefit will not be less than the current Specified Amount of the Policy,
reduced by any outstanding indebtedness and any due and unpaid charges. The
minimum initial Specified Amount of a Policy is $25,000. The Specified Amount
may not be reduced to less than $25,000, except when required by a withdrawal.
The Specified Amount may not be reduced to less than $10,000 after a
withdrawal.

 The Policy provides two death benefit options which may be chosen by the
policyowner. Under Option I, the death benefit payable under the Policy is
equal to the greater of (i) the Specified Amount or (ii) the Policy's
accumulation value on the date of death multiplied by the "corridor
percentage". The corridor percentage is a tax law concept pertaining to the
relationship between accumulation value and death benefit, based on the
Insured's attained age. Under Option II, the death benefit equals the
Specified Amount plus the accumulation value of the Policy on the date of
death, but not less than the Policy's accumulation value multiplied by the
corridor percentage. The policyowner may, subject to certain restrictions,
change from one death benefit option to the other after the Policy has been
issued.

 The initial premium payment must be sufficient to keep the Policy in force
for at least three months. No premium payment may be less than $25. The total
of all premiums paid may never exceed the current maximum premium limitations
set forth in the Internal Revenue Code of 1986 (the "Code"). The limitation on
total premiums paid is imposed in order to comply with present requirements
for the definition of life insurance to obtain favorable federal income tax
treatment of the Policy and its death benefit.

 The Policy will remain in force so long as cash value exceeds indebtedness
and cash value less indebtedness is sufficient to pay certain monthly charges
imposed in connection with the Policy. The cash value equals the accumulation
value less any surrender charge. Accumulation value in Separate Account B will
reflect the investment experience of the chosen divisions of Separate Account
B, the amount and frequency of premium payments, any withdrawals, and charges
imposed in connection with the Policy. Adherence to the schedule of Planned
Periodic Premiums will not assure the Policy will remain in force. The
policyowner bears the entire investment risk for all amounts allocated to
Separate Account B; no minimum accumulation value is guaranteed and the
accumulation value could decline to zero. So long as cash value exceeds
indebtedness and subject to certain conditions described in this Prospectus, a
policyowner may obtain policy loans at any time after the first policy
anniversary and may make withdrawals at any time. Both withdrawals and policy
loans must be made prior to the Policy's maturity date.
   
 The policyowner may allocate net premiums to one or more of the divisions of
Separate Account B or to Chubb Colonial's General Account on the allocation
date. Each division of Separate Account B will invest solely in a
corresponding portfolio (a "Portfolio") of Jefferson Pilot Variable Fund,
Inc., Templeton Variable Products Series Fund, Fidelity Variable Insurance
Products Fund, Fidelity Variable Insurer Products Fund II, Oppenheimer
Variable Account Fund or MFS Variable Insurance Trust (collectively, the
"Funds"). Prior to the allocation date the net premiums paid will be deposited
in Chubb Colonial's General Account. There is a period during which the
policyowner may cancel the Policy. If the policyowner elects during this "free
look" period to cancel the Policy, Chubb Colonial will reimburse, within seven
days from the date the Policy is surrendered to Chubb Colonial, the full
amount of premium paid. The accompanying Prospectuses for the Funds and the
Statements of Additional Information, available on request, describe the
investment objectives and risks of the nineteen Portfolios.     

 Prospective purchasers of this Policy are advised that replacement of
existing insurance coverage may not be financially advantageous and should
consult with their financial advisers with respect to the Policy. It may also
not be advantageous to purchase this Policy, if the prospective purchaser
already owns a flexible premium variable life insurance policy.
 This Prospectus generally describes only the portion of the Policy involving
Separate Account B. For a brief summary of Chubb Colonial's General Account,
see "THE GENERAL ACCOUNT."

"Policy") issued by Chubb Colonial Life Insurance Company ("Chubb Colonial"),
the policyowner may, subject to certain limitations, make premium payments in
any amount at any frequency. The Policy is a life insurance contract with death
benefits, cash values, and other features traditionally associated with life
insurance. It is called "flexible premium" because, unlike many insurance
contracts, there is no fixed schedule for premium payments, although each
policyowner may establish a schedule of premium payments ("Planned Periodic
Premiums"). This flexibility permits a policyowner to provide for evolving
insurance needs within a single insurance product. The minimum initial
Specified Amount is $25,000. A policyowner under attained age 85 may increase
or decrease coverage. Increasing coverage under the Policy, rather than
purchasing another policy, may save additional administrative costs. Increasing
coverage under the Policy or purchasing another policy may require new evidence
of insurability. Increasing coverage may have certain tax consequences. See
"Federal Tax Matters."
 
 The Policy is called "variable" because, unlike the fixed benefits of an
ordinary whole life insurance contract, the accumulation value, the cash value
and, under certain circumstances, the death benefit of the Policy may increase
or decrease depending upon the investment experience of the divisions of
Colonial Separate Account B ("Separate Account B") to which premium payments
have been allocated. So long as the Policy's cash value continues to be
sufficient to pay the monthly deduction, all policyowners are guaranteed a
minimum death benefit equal to the face amount of the Policy (the "Specified
Amount"), less any outstanding policy debt.
 
 The death benefit is payable under two options. Under Option I, the death
benefit is equal to the greater of the Specified Amount or the accumulation
value of the Policy on the date of death multiplied by the corridor percentage.
Under Option II, the death benefit is equal to the sum of the Specified Amount
and the Policy's accumulation value on the date of death, subject to adjustment
by the corridor percentage. The corridor percentage is a tax law concept
pertaining to the relationship between accumulation value and the death
benefit, based on the Insured's attained age. Prospective policyowners should
be aware that there is no guarantee of accumulation value in Separate Account
B. See "POLICY BENEFITS AND RIGHTS--Death Benefits."
   
 Colonial Separate Account B. Separate Account B is a separate account
established by Chubb Colonial pursuant to the insurance laws of the State of
New Jersey and organized as a registered unit investment trust under the
Investment Company Act of 1940 (the "1940 Act"). Such registration does not
involve any supervision by the Securities and Exchange Commission (the
"Commission") of the management or investment practices or policies of Separate
Account B. Separate Account B is presently comprised of nineteen divisions,
each of which buys shares at net asset value of the corresponding portfolio (a
"Portfolio") of Jefferson Pilot Variable Fund, Inc., Templeton Variable
Products Series Fund, Fidelity Variable Insurance Products Fund, Fidelity
Variable Insurance Products Fund II, MFS Variable Insurance Trust or
Oppenheimer Variable Account Funds (the "Funds"). Separate Account B is
administered and accounted for as part of the general business of Chubb
Colonial, but the income, capital gains, or capital losses of Separate Account
B are credited to or charged against the assets held in the account in
accordance with the terms of the Policy, without regard to other income or
capital gains or losses of any other account arising out of any other business
Chubb Colonial conducts. The assets of Separate Account B are not chargeable
with liabilities arising out of any other business conducted by Chubb Colonial.
The income and both realized and unrealized gains or losses on the assets of
each division are separate and are credited or charged against each division
without regard to income, gains or losses from any other division. See
"CALCULATION OF ACCUMULATION VALUE--Unit Values."     
   
 A policyowner may allocate net premium payments among the General Account and
the divisions of Separate Account B which invest in Portfolios of the Funds.
Over the life of the Ensemble II contract net premium payments may be allocated
among a total of seventeen divisions of Separate Account B.

 If the Date of Receipt of the initial premium is prior to the date Chubb
Colonial either issues the Policy or offers to issue the Policy on a basis
other than as applied for, and that initial premium exceeds $500, the net
premium, less any monthly deductions, will be credited with interest at the
rate currently being credited to the General Account. This amount will be
credited with interest for the period between the Date of Receipt of the
premium (or the policy date, whichever is later) and the date Chubb Colonial
issues the Policy or the applicant refuses Chubb Colonial's offer to issue the
Policy on a basis other than as applied for. If the initial premium is $500 or
less, no interest will be credited. In those instances when Chubb Colonial
declines to issue a Policy, the entire premium paid will be returned. If the
initial premium exceeds $500 it will be returned with interest. Interest will
be credited from the Date of Receipt to the date the application is rejected.
If the Policy issued as applied for is not accepted or the "free look" is
exercised, no interest will be credited. Chubb Colonial will retain any
interest earned on the initial net premium. Prior to the allocation date the
initial net premium will be deposited in Chubb Colonial's General Account. See
"The Policy--Policy "Free Look" ".

 Over the life of an Ensemble II contract, policyowners may allocate net
premiums to a total of seventeen divisions of Separate Account B.     
 
 Policyowners should be aware that there can be no assurance that any Portfolio
will in fact achieve its stated objectives. Policyowners should read and retain
the prospectuses for the Funds which accompanies this Prospectus for detailed
information. See "THE FUNDS".
 
 Premiums. The first premium is due on the policy date. Premiums are paid in
advance, generally one year at a time; however, Chubb Colonial permits semi-
annual, quarterly and monthly premium payments. Changes in frequency and
increases or decreases in the amount of Planned Periodic Premiums may be made
by the policyowner provided that the total of all premiums, scheduled and
unscheduled, cannot exceed the current maximum premium limitations for the
definition of life insurance, set forth in the Code. Chubb Colonial will return
any excess premiums if the total of all premiums, scheduled and unscheduled,
will exceed these limits. Chubb Colonial will notify policyowners if any
premiums, scheduled or unscheduled, would cause the Policy to be deemed a
modified endowment contract and allow for a refund of the excess premium. See
"FEDERAL TAX MATTERS--Policy Proceeds".
 
 Chubb Colonial reserves the right to limit the amount of any increase in
premium payment. No premium payment may be less than $25. Subject to the
foregoing limitations, a policyowner may make additional premium payments at
any time prior to the maturity date of the Policy. See "THE POLICY--Payment of
Premiums".
 
 Failure to pay premiums in accordance with the schedule of Planned Periodic
Premiums will not automatically cause the Policy to lapse. It will lapse only
when the cash value less outstanding policy debt is insufficient to pay the
monthly deduction and a grace period expires without a sufficient payment by
the policyowner. Conversely, payment of premiums in accordance with the
schedule of Planned Periodic Premiums does not necessarily mean that the Policy
will remain in force. See "THE POLICY--Policy Lapse".
 
 Death Benefit. The death benefit under the Policy is the amount payable to the
named beneficiary when the person insured under the Policy dies. All or part of
the death benefit may be paid in cash or applied under one or more of the
payment options available under the Policy. See "POLICY BENEFITS AND RIGHTS--
Settlement Options". The death benefit will be reduced by the amount of any
outstanding policy debt or unpaid monthly deduction.
 
 Under Option I, the death benefit will be equal to the greater of the
Specified Amount or the accumulation value of the Policy on the date of death
multiplied by the corridor percentage. Under Option II, the death benefit is
equal to the Specified Amount plus the accumulation value of the Policy on the
date of death; provided, however, that under Option II, the death benefit can
never be less than the accumulation value on the date of death multiplied by
the corridor percentage. See "POLICY BENEFITS AND RIGHTS--Death Benefits".
 
 A policyowner may, by written request, change the Specified Amount subject to
the following conditions:
 
  1. Any requested decrease in Specified Amount, which may only be made after
 a Policy has been in force for one year, will become effective on the monthly
 anniversary date that coincides with, or next follows, receipt of such
 request. The minimum decrease in Specified Amount is $25,000. No decrease may
 reduce the Specified Amount below $25,000.
 
  2. Any request for an increase in Specified Amount, which may be made at
 anytime after the Policy has been issued, must be applied for, by a
 supplemental application, prior to attained age 85, and shall be subject to
 evidence of insurability satisfactory to Chubb Colonial. The minimum increase
 in Specified Amount is $25,000.
 
  3. Any change approved by Chubb Colonial will become effective on the date
 shown in the Supplemental Policy Specification Page of the Policy, subject to
 deduction of the first month's cost of insurance from the accumulation value
 of the Policy.
 
 By written request, a policyowner may also change the death benefit option. If
the request is to change from Option I to Option II, the Specified Amount will
be decreased by the amount of the accumulation value of the Policy on the
effective date of the change. Evidence of insurability satisfactory to Chubb
Colonial will be required for change from Option I to Option II. The effective
date of the change from Option I to Option II will be the monthly anniversary
date that coincides with or next follows the date of underwriter approval. If
the request is to change from Option II to Option I, the Specified Amount will
be increased by the amount of the accumulation value of the Policy on the
effective date of the change. No
 
                                       7
<PAGE>
 
evidence of insurability is required for a change from Option II to Option I.
The effective date of the change from Option II to Option I will be the monthly
anniversary date that coincides with or next follows the date that coincides
with or next follows the Date of Receipt of the request for change. The
effective date of either change shall be the monthly anniversary date that
coincides with or next follows the Date of Receipt of the request for change.
See "POLICY BENEFITS AND RIGHTS--Death Benefits". Policyowners may combine a
request for a change in the Specified Amount with a request for a change in the
death benefit option. Combined requests will be subject to the requirements and
limitations of each of the requests. See "POLICY BENEFITS AND RIGHTS--Combined
Requests."
 
 Value of Policy. The Policy provides for accumulation value equal to the total
of accumulation value in the General Account and the Policy's accumulation
value in divisions of Separate Account B. The Policy's accumulation value will
reflect the amount and frequency of premium payments, the value of net premiums
(net premiums plus credited interest), if any, allocated to the General
Account, the investment experience of Separate Account B, policy loans, any
withdrawals, and any charges imposed in connection with the Policy. There is no
minimum guaranteed accumulation value.
 
 The accumulation value of each division in Separate Account B on the
allocation date is equal to the net premiums, plus interest earned prior to the
allocation date, which have been paid and allocated to that division less the
portion of the first monthly deduction allocated to the Policy's accumulation
value in that division. Thereafter, at the end of each valuation period after
the initial allocation, the Policy's accumulation value in a division is equal
to the sum of (a) the accumulation value in the division on the preceding
valuation date multiplied by the net investment factor (See "CALCULATION OF
ACCUMULATION VALUE--Net Investment Factor") for the current valuation period,
plus (b) any net premium received during the current valuation period which is
allocated to the division, plus (c) all accumulation values transferred to the
division from another division or the General Account, including loan
repayments, during the current valuation period, minus (d) accumulation values
transferred from the division to another division or the General Account and
accumulation values transferred to secure a policy debt during the current
valuation period, and minus (e) all withdrawals from the division during the
current valuation period, and minus (f) a pro-rata portion of monthly
deductions, whenever a valuation period includes the monthly anniversary date.
 
 The Policy's total accumulation value in Separate Account B equals the sum of
the Policy's accumulation value in each division. The Policy's accumulation
value in Separate Account B is expressed in terms of the number of units and
unit values of each division. See "CALCULATION OF ACCUMULATION VALUE--Unit
Values."
 
 Charges and Deductions.
 
 (a) Chubb Colonial deducts 2.0% of each premium payment received to compensate
Chubb Colonial for state premium taxes, franchise taxes and other local taxes
imposed on premiums by New York State and local jurisdictions. The actual taxes
imposed on Colonial may fall between 1.7% and 2.5% of premiums received. As a
result, the 2.0% charge may at times be higher or lower than the actual tax
incurred by Colonial. Colonial reserves the right to increase this charge to
Policyowners up to a maximum of 2.50%. Colonial does not expect to realize a
profit as a result of this charge.
 
 (b) There is a monthly deduction from each Policy's accumulation value in the
General Account and/or one or more divisions of Separate Account B equal to the
sum of (i) the cost of insurance, described below, and the cost of additional
benefits provided by rider attached to the Policy; and (ii) a monthly
administrative charge of $6.00. The cost of insurance charge is calculated on
each monthly anniversary date. It is based on the sex, issue age, policy year,
rating class of the Insured, and Specified Amount of the Policy. Monthly cost
of insurance rates will be determined by Chubb Colonial based upon its
expectations as to future mortality experience. Cost of insurance rates are
guaranteed not to exceed or be increased above the maximum charge based upon
the Commissioner's 1980 Standard Ordinary Mortality Table.
 
 (c) A mortality and expense risk charge, not to exceed .0024657% on a daily
basis (.90% on an annual basis) for policy years one through ten and .0017808%
on a daily basis (.65% on an annual basis) for policy years eleven and
thereafter will be imposed on the assets of each division. Chubb Colonial will
realize a gain from this charge to the extent it is not needed to provide
benefits and pay expenses under the Policy.
 
 (d) Upon surrender or withdrawal, Chubb Colonial will assess a surrender
charge. The surrender charge for the initial Specified Amount is determined by
multiplying a surrender factor by the lesser of (1) the premiums actually
received in policy year one, or (2) the "Guideline Annual Premium" as defined
in the rules under the 1940 Act. Subject to other
 
                                       8
<PAGE>
 
considerations, the surrender charges may be reduced by paying less premium in
policy year one. The surrender factor depends on the length of time the Policy
has been in force and ranges between 0% and 30% of the premium paid in policy
year one. The surrender charge for increases in the Specified Amount is
determined in a similar manner. The surrender charge is more fully described
under "CHARGES AND DEDUCTIONS--Surrender Charge".
 
 (e) Chubb Colonial charges an administrative fee equal to the lesser of $25 or
2% of the amount of the withdrawal for each withdrawal and the lesser of $25 or
10% of the amount of a transfer for each transfer between divisions of Separate
Account B or the General Account. Chubb Colonial reserves the right to assess a
charge, not to exceed $25, for each request by a policyowner for an
illustration of benefits and values after the policy date.
 
 (f) Chubb Colonial reserves the right to charge the assets of each division of
Separate Account B to provide for any income taxes payable by Chubb Colonial on
the assets of such divisions. In addition, an investment advisory fee is
imposed against the assets of each Portfolio to compensate the Funds'
investment manager and sub-investment managers. See "THE FUNDS".
 
 Policy Loans. After the first policy anniversary, a policyowner may borrow
against the cash value of his Policy. Generally, the maximum loan amount is 90%
of the cash value of the Policy on the date of the loan. Loan interest is
payable at the end of each policy year and all policy debt outstanding will be
deducted from proceeds payable at the Insured's death, upon maturity, or upon
surrender.
 
 A policyowner may allocate a policy loan among the General Account and the
various divisions of Separate Account B. Accumulation value in each division
equal to the policy debt so allocated will be transferred to the General
Account. If loan interest is not paid when due, it becomes loan principal. An
amount equal to the unpaid loan interest will be transferred to the General
Account pro-rata from the accumulation value of the General Account and the
divisions of Separate Account B. If no accumulation value is available in any
of the divisions of Separate Account B, accumulation value held in the General
Account will be set aside as loan collateral. Accumulation value held in the
General Account for loan collateral earns interest daily at an annual rate of
6%.
 
 Chubb Colonial will charge interest on any outstanding policy loan with such
interest compounded annually. There are two types of loans available. A Type A
loan is charged the same interest rate as the interest credited to the amount
of accumulation value which is held in the General Account to secure loans. The
amount available at any time for a Type A loan equals the maximum loan amount
less the DEFRA Guideline Single Premium, as set forth in the Code, less any
outstanding Type A loans. All other loans are Type B loans; a Type B loan is
charged an interest rate of 8%. It is possible for one loan request to result
in both a Type A and Type B loan. Interest accrues on a daily basis from the
date of the loan and is compounded annually. A policy loan may be prepaid in
whole or in part at any time while the Policy is in force. When a loan
repayment is made, accumulation value securing the policy debt in the General
Account equal to the loan repayment will be allocated among the General Account
and divisions of Separate Account B using the same percentages as used to
allocate net premiums. See "CASH VALUE BENEFITS--Policy Loans".
 
 If a policyowner elects to surrender the policy or allows the policy to lapse,
the policyowner may be taxed on a portion of any amounts paid to the
policyowner which may include prior loans cancelled in the transaction. See
"FEDERAL TAX MATTERS".
 
 Policy Cancellation, Surrender and Lapse. The policyowner has the limited
right to return a Policy for cancellation and full refund of all premiums paid.
Chubb Colonial will cancel the Policy if it is returned by mail or personal
delivery to Chubb Colonial or to the agent who sold the Policy, within 20 days
after the delivery of the Policy to the policyowner, within 45 days of the date
of the execution of the application for insurance, or within 20 days after
mailing or personal delivery of a Notice of the Right of Withdrawal, whichever
is later. Chubb Colonial will return to the policyowner, within seven days, all
payments received on the Policy. Prior to the allocation date, the initial net
premium will be deposited in Chubb Colonial's General Account; Chubb Colonial
will retain any interest earned if the "free look" right is exercised.
 
 So long as the Policy is in force, a policyowner may elect, subject to the
consent of any irrevocable beneficiary or assignee of the Policy, to surrender
the Policy and receive its cash value, i.e., the cash value of the Policy
determined as of the day Chubb Colonial receives the policyowner's written
request, less any outstanding policy debt secured by the Policy. A policyowner
may also request a withdrawal, subject to the consent of any irrevocable
beneficiary, of the cash value of the
 
                                       9
<PAGE>
 
Policy. Normally, a withdrawal reduces the death benefit payable under the
Policy by an amount equal to the reduction in the Policy's accumulation value
plus a pro-rata portion of the surrender charge.
 
 Failure to make any premium payment on a Policy will not necessarily cause the
Policy to lapse. The duration of a Policy depends upon the cash value. The
Policy will remain in force so long as the cash value less any outstanding
policy debt is sufficient to pay the monthly deduction. In the event the cash
value, less any outstanding policy debt, is insufficient to pay the monthly
deduction and a sixty-one day grace period expires without an adequate payment
by the policyowner, the Policy will lapse and terminate without value. See "THE
POLICY--Policy Lapse."
 
 Once a Policy has lapsed, the policyowner may request reinstatement of the
Policy anytime within five years of lapse. Satisfactory proof of insurability
and payment of a reinstatement premium are required for reinstatement. See "THE
POLICY--Reinstatement."
   
 Distribution of the Policy. Chubb Colonial will offer the Policy only in New
York. The Policy will be sold by agents who represent Chubb Colonial and are
registered representatives of registered broker-dealers.     
 
 Tax Consequences of the Policy. All death benefits paid under the Policy will
generally be fully excludable from the gross income of the policy beneficiary
for federal income tax purposes. Treasury regulations require that investments
underlying the Policy be adequately diversified. Chubb Colonial believes it is
presently in compliance with the regulations and intends to remain in
compliance with such regulations and other federal tax law requirements.
 
 Chubb Colonial may charge each division in Separate Account B for its portion
of any income tax charged to Chubb Colonial on the division or its assets. The
charge, if imposed, will reduce the investment return of Separate Account B.
 
 If a policyowner elects to make certain transactions, including a partial
withdrawal, surrender or exchange of the Policy, or receipt of accelerated
benefits pursuant to the Terminal Illness Accelerated Benefit Rider, or allows
the policy to lapse, the policyowner may be taxed on a portion of any amounts
paid to the policyowner (which may include any prior policy loans cancelled in
the transaction). Also, if premiums paid by a policyowner exceed certain limits
and the Policy is deemed a modified endowment contract, then any pre-death
distributions, including loans, surrenders and partial withdrawals, may be
treated as income taxable to the policyowner and may also cause the policyowner
to incur a penalty tax of 10%. Policyowners are advised to consult with their
own tax advisers with regard to the tax consequences of the Policy. See
"FEDERAL TAX MATTERS".

                     CHUBB COLONIAL LIFE INSURANCE COMPANY
 
 Chubb Colonial is a stock life insurance company chartered in 1897 in New
Jersey and has been continuously engaged in the insurance business since that
time. Prior to March 1, 1996 Chubb Colonial was known as "The Colonial Life
Insurance Company of America". It is licensed to do life insurance business in
fifty states of the United States, Puerto Rico, the U.S. Virgin Islands, and
in the District of Columbia. Chubb Colonial is a wholly-owned subsidiary of
Chubb Life Insurance Company of America, ("Chubb Life") a New Hampshire life
insurance company which, effective April 30, 1997, is a wholly-owned
subsidiary of Jefferson-Pilot Corporation, a North Carolina Corporation. The
principal offices of Jefferson-Pilot Corporation are located at 100 North
Greene Street, Greensboro, North Carolina 27401. Its telephone number is
910-691-3000. Chubb Life's home office and Chubb Colonial's service center are
located at One Granite Place, Concord, New Hampshire 03301, telephone number
(800) 258-3648. Chubb Colonial's home office is located at Eight Sylvan Way,
Parsippany, New Jersey 17054, telephone number (201) 455-1400. Chubb
Colonial's total assets at December 31, 1996 were $602,728,000.
   
 Chubb Colonial writes life and health insurance and annuities. It is subject
to New Jersey law governing insurance, and is regulated and supervised by the
New Jersey Insurance Commissioner. Chubb Colonial is also subject to the
insurance laws of New York. Contemporaneous with the sale of Chubb Life and
its subsidiaries to Jefferson-Pilot Corporation, Chubb Colonial is currently
rated AAA by Duff & Phelps, AA (Excellent) by Standard & Poors's Corporation
and A by A.M. Best and Company. These ratings merely reflect the opinion of
the rating company as to the relative financial strength of Chubb Colonial and
Chubb Colonial's ability to meet its contractual obligations to its
policyowners. Even though assets in Separate Account B are held separately
from Chubb Colonial's other assets, ratings of Chubb Colonial may still be
relevant to policyowners since not all of Chubb Colonial's contractual
obligations relate to payments based on those segregated assets.     
 
                          COLONIAL SEPARATE ACCOUNT B
 
 Separate Account B is a separate account of Chubb Colonial established on
March 2, 1994 and governed by the insurance laws of the State of New Jersey.
Separate Account B is organized as a unit investment trust registered with the
Commission under the 1940 Act and is subject to that Act's requirements. Such
registration does not involve supervision of the management or investment
policies of Separate Account B or Chubb Colonial by the Commission. Chubb
Colonial is the depositor of Separate Account B. Under New Jersey law, the
assets of Separate Account B are held exclusively for the benefit of
policyowners and persons entitled to payments under this Policy and other
variable life insurance policies funded by Separate Account B. The assets of
Separate Account B are not chargeable with liabilities arising out of any
other business which Chubb Colonial may conduct.
 
 Chubb Colonial holds the assets of Separate Account B. These assets are kept
physically segregated and held separate and apart from the General Account.
Chubb Colonial maintains records of all purchases and redemptions of Funds
shares by each of the divisions.
   
 Divisions. Separate Account B presently has nineteen investment divisions but
may, in the future, add or delete investment divisions. Each investment
division will invest exclusively in shares representing an interest in a
Portfolio of the Funds.     
 
 Investment income and other distributions to each division of Separate
Account B arising from the applicable underlying Portfolio of the Funds
increases the assets of the corresponding division of Separate Account B. The
income and both realized and unrealized gains or losses on the assets of each
division of Separate Account B are credited to or charged against that
division without regard to income, gains or losses from any other division.
Under certain unusual circumstances, the liabilities of one division, arising
from claims against that division, could be attributed to another division.

 Jefferson Pilot Variable Fund, Inc., (formerly The Chubb America Fund, Inc.)
Jefferson Pilot Variable Fund, Inc. is organized as a Maryland corporation and
is registered as an open-end diversified management company under the 1940
Act. The Jefferson Pilot Variable Fund, Inc. currently has eleven Portfolios,
each of which has different objectives and ten of which are offered to a
corresponding division of Separate Account B (Gold Stock Portfolio is not
available). The shares of each series of Jefferson Pilot Variable Fund, Inc.
stock are presently offered only to the divisions of separate accounts of
Chubb Colonial and its affiliated life insurance companies. The assets of each
Portfolio are maintained separately from the assets of the other Portfolios
and each Portfolio has investment objectives and policies which are different
from those of the other Portfolios. Thus, each Portfolio operates as a
separate investment fund, and the income, gains or losses of one Portfolio
generally has no effect on the investment performance of any other Portfolio.
Under certain unusual circumstances, the liabilities of one Portfolio, arising
from claims against that Portfolio, could be attributed to another Portfolio.
       
 The investment manager to Jefferson Pilot Variable Funds, Inc., is Jefferson
Pilot Investment Advisory Corporation ("JP Investment Advisory") (formerly
Chubb Investment Advisory Corporation), which is an affiliate of Chubb
Colonial. JP Investment Advisory and the Fund have contracted with ten
unaffiliated companies, Templeton Global Advisors, Inc. ("Templeton"), Lombard

Investment Management, Inc. ("Morgan"), Massachusetts Financial Services
Company ("MFS"), Chubb Asset Managers, Inc. ("CAM"), Strong Capital
Management, Inc. ("Strong"), and Warburg Pincus Asset Management, Inc.,
formerly Warburg Pincus Counsellors, Inc. ("Warburg") (collectively the "Sub-
Investment Managers") to act as sub-investment managers or advisers to the
World Growth Stock, International Equity, Gold Stock, Domestic Growth Stock,
Capital Growth, Balanced, High Yield Bond, Emerging Growth and Money Market,
Growth, and Growth and Income Portfolios, respectively. The fees of the Sub-

 The investment objectives of each Portfolio of Jefferson Pilot Variable Fund,
Inc. which offer their shares to a corresponding division of Separate Account
B are set forth below.     
   
 World Growth Stock Portfolio: to achieve long-term capital growth through a
policy of investing primarily in stocks of companies organized in the United
States or in any foreign nation. A portion of the Portfolio may also be
invested in debt obligations of companies and governments of any nation. Such
companies will be those considered by the sub-investment manager to be
undervalued or which are well-managed and have good growth potential. Any
income realized from such investments will be incidental.     
   
 International Equity Portfolio: to achieve long-term capital appreciation by
investing substantially all of its total assets in equity and equity-related
securities of companies from countries outside of the United States.     
   
 Money Market Portfolio: to achieve the highest possible level of current
income, consistent with preservation of capital and maintenance of liquidity,
by investing primarily in short-term money market instruments. An investment
in the Money Market Portfolio is neither insured nor guaranteed by the U.S.
Government.     
          
 High Yield Bond Portfolio: to achieve a high level of current income by
investing primarily in corporate obligations with emphasis on higher-yielding,
higher risk, lower-rated or unrated securities.     
 
 Domestic Growth Stock Portfolio: to achieve reasonable income and growth of
capital by investing primarily in a diversified portfolio of equity securities
issued by companies organized in the U.S. and considered by the sub-investment
manager to be undervalued in light of the company's earning power and growth
potential.
   
 Growth Portfolio: to achieve capital growth by investing primarily in equity
securities believed by the Portfolio's sub-adviser to have above-average
growth prospects.     
 
 Growth and Income Portfolio: to seek long-term growth of capital by investing
primarily in a wide range of equity issues that may offer capital appreciation
and, secondarily, to seek a reasonable level of current income.
 
 Capital Growth Portfolio: to seek capital growth. Realization of income is
not a significant investment consideration and any income realized will be
incidental. The Capital Growth Portfolio will invest primarily in common
stocks.
 
 Balanced Portfolio: to seek reasonable current income and long-term capital
growth, consistent with conservation of capital, by investing primarily in
common stocks and fixed income securities.
 
 Emerging Growth Portfolio: to seek long-term growth of capital by investing
primarily in common stocks of small and medium-sized companies. The Portfolio
is intended for investors who understand and are willing to accept risks
entailed in seeking long-term growth of capital.
   
 Jefferson Pilot Variable Fund, Inc. may find it necessary to take action to
assure that the Policy continues to qualify as a life insurance policy under
federal tax laws. Jefferson Pilot Variable Fund, Inc., for example, may alter
the investment objectives of any Portfolio or take other appropriate actions.
See "OTHER MATTERS--Additions, Deletions or Substitutions of Investments" and
"FEDERAL TAX MATTERS".     
 
 Templeton Variable Products Series Fund. Templeton Variable Products Series
Fund is an open-end, diversified management investment company organized under
the laws of Massachusetts. Templeton Variable Products Series Fund currently
consists of five separate series; however, only one of the series, the
Templeton International Fund, offers its shares to a corresponding division of
Separate Account B. Templeton Variable Products Series Fund offers its shares
solely to separate accounts of insurance companies, including companies not
affiliated with Chubb Colonial, as an investment vehicle for variable life
insurance policies and variable annuity contracts.
 
 The investment manager of Templeton International Fund is Templeton
Investment Counsel, Inc. ("TICI"). TICI is an indirect wholly owned subsidiary
of Franklin Resources, Inc. ("Franklin"). Through its subsidiaries, Franklin
is engaged in various aspects of the financial services industry. As
compensation for its services, TICI is paid a fee which, on an annual basis,
represents .75% of the average daily net assets of the Fund up to $200
million, .675% of such assets from $200 million up to $1.3 billion, and .60%
of such assets in excess of $1.3 billion of the average daily net assets of
the Templeton International Fund.
 
                                      13
<PAGE>
 
 The investment objective of the Templeton International Fund is set forth
below.
 
 Templeton International Fund: to seek long-term capital growth through a
flexible policy of investing in stocks and debt obligations of companies and
governments outside the United States. Any income realized will be incidental.
Although the Templeton International Fund generally invests in common stock,
it may also invest in preferred stocks and certain debt securities such as
convertible bonds which are rated in any category by Standard & Poor's
Corporation or Moody's Investors Service, Inc. or which are unrated by any
rating agency.
 
 Although Chubb Colonial does not currently foresee any disadvantages to the
policyowners arising out of variable life insurance separate accounts and
variable annuity separate accounts investing in the Templeton Variable
Products Series Funds simultaneously, there is a possibility that a material
conflict may arise between the interest of Separate Account B and one or more
of the other separate accounts investing in the Templeton Variable Products
Series Fund. The Trustees of the Templeton Variable Products Series Fund
intend to monitor events in order to identify any material conflicts and to
determine what action, if any, should be taken in response thereto. Material
conflicts could result from, for example, (i) changes in state insurance laws,
(ii) changes in Federal income tax laws, (iii) changes in the investment
management of any portfolio of Templeton Variable Products Series Fund, or
(iv) differences in voting instructions between those given by variable life
insurance policyowners and those given by variable annuity contract owners.
   
 Fidelity Variable Insurance Products Fund and Fidelity Variable Insurance
Products Fund II. Fidelity Variable Insurance Products Fund ("Fidelity VIP")
and Fidelity Variable Insurance Products Fund II ("Fidelity VIPII") are open-
end, diversified management investment companies organized as Massachusetts
business trusts on November 13, 1981 and March 21, 1988, respectively.
Fidelity VIP currently consists of four separate series; however, only one of
the series, High Income Portfolio, offers its shares to a corresponding
division of Separate Account B. Fidelity VIPII currently consists of five
separate series; however, only two of the series, Contrafund Portfolio and
Index 500 Portfolio, offer their shares to corresponding divisions of Separate
Account B. Fidelity VIP and Fidelity VIPII offer their shares solely to
separate accounts of insurance companies, including companies not affiliated
with Chubb Colonial, as investment vehicles for variable life insurance
policies and variable annuity contracts.     
 
 Fidelity Management & Research Company ("FMR") is the investment manager of
Fidelity VIP and Fidelity VIPII. FMR is the management arm of Fidelity
Investments, a Massachusetts corporation established in 1946. FMR is a wholly-
owned subsidiary of FMR Corp. Through its subsidiaries, FMR is engaged in
various aspects of the Financial services industry. Each fund pays a
management fee to FMR for managing its investments and business affairs. Each
fund's management fee is calculated and paid to FMR every month. The fee for
each fund (excluding Money Market and Index 500 Portfolios) is calculated by
adding a group fee rate to an individual fund fee rate, and multiplying the
result by each fund's average net assets. The group fee rate is based on the
average net assets of all the mutual funds advised by FMR. This rate cannot
rise above 0.52% for the Contrafund Portfolio and 0.37% for the High Income
Portfolio, and it drops as total assets under management increase. Index 500
Portfolio pays a monthly management fee to FMR at the annual rate of 0.28% of
the Fund's average net assets.
 
 The investment objectives of each Portfolio of Fidelity VIP and Fidelity
VIPII in which Separate Account B invests are set forth below:
   
 Equity Income Portfolio: seeks reasonable income by investing primarily in
income-producing equity securities.     
   
 Growth Portfolio: seeks capital appreciation by investing primarily in common
stocks.     
 
 Contrafund Portfolio: seeks long term capital appreciation.
 
 Index 500 Portfolio: seeks investment results that correspond to the total
return of common stocks publicly traded in the United States, as represented
by the S&P 500.
   
 Although Chubb Colonial does not currently foresee any disadvantages to its
policy and certificate owners arising out of variable life insurance separate
accounts and variable annuity separate accounts investing in the Fidelity VIP
and VIPII Funds simultaneously, there is a possibility that a material
conflict may arise between the interest of Separate Account B and one or more
of the other separate accounts investing in the Fidelity VIP and VIPII Funds.
The Trustees of the VIP and VIPII Funds intend to monitor events in order to
identify any material conflicts and to determine what action, if any, should
be taken in response thereto. Material conflicts could result from, for
example, (i) changes in state insurance laws,     
 
                                      14

(ii) changes in Federal income tax laws, (iii) changes in the investment
management of any portfolio of Fidelity VIP and VIPII Funds, or (iv)
differences in voting instructions between those given by variable life
insurance policy and certificate owners and those given by variable annuity
contract owners.     
   
 MFS Variable Insurance Trust (the "MFS Trust") is an open-end management
investment company organized as a business trust under the laws of The
Commonwealth of Massachusetts by a Declaration of Trust dated February 1,
1994. The Trust offers insurance company separate accounts a selection of
investment vehicles for variable annuity and variable life insurance
contracts. Currently the Trust offers shares of beneficial interest of twelve
separate mutual fund series, two of which, MFS Research Series and MFS
Utilities Series, offer their shares to a corresponding division of Separate
Account B.     
   
 The Trust's Board of Trustees, as part of its overall management
responsibility, oversees various organizations responsible for each Series'
day-to-day management. Massachusetts Financial Services company ("MFS" or the
"Adviser"), a Delaware corporation, is the investment adviser to each Series.
For its services and facilities, MFS receives a management fee computed and
paid monthly, in an amount equal to the following annual rates of the average
daily net assets of each Series:

 MFS or its affiliates will pay a fee to Chubb Colonial equal, on an
annualized basis, to 0.15% of the aggregate net assets of each Series,
attributable to Contracts offered by separate accounts of Chubb Colonial or
its affiliates. Such fees will not be paid by the Series, its shareholders or
by the Contract holders.     
   
 The investment objectives of each Series of the Trust are set forth below:
       
 Research Series: seeks to provide long-term growth of capital and future
income by investing a substantial proportion of its assets in equity
securities of companies believed to possess better than average prospects for
long-term growth.     
   
 Utilities Series: seeks capital growth and current income (incomes above that
available from a portfolio invested entirely in equity securities) by
investing, under normal circumstances, at least 65% (but up to 100% at the
discretion of the Adviser) of its assets in equity and debt securities of both
domestic and foreign companies in the utilities industry.     
   
 Oppenheimer Variable Account Funds (the "Oppenheimer Trust") is an open-end
diversified management investment company organized in 1984 as a Massachusetts
business trust. The Oppenheimer Trust consists of nine separate funds, two of
which, the Bond Fund and the Strategic Bond Fund, offer their shares to a
corresponding division of Separate Account B.     
   
 The Oppenheimer Variable Account Funds are managed by OppenheimerFunds, Inc.,
which is responsible for selecting the Funds' investments and handling its
day-to-day business.     
   
 The monthly management fee payable to the Manager is computed separately on
the net assets of each Fund as of the close of business each day. The
management fee rates for the Bond Fund and the Strategic Bond Fund are as
follows: 0.75% of the first $200 million of average annual net assets, 0.72%
of the next $200 million, 0.69% of the next $200 million, 0.66% of the next
$200 million, 0.60% of the next $200 million and 0.50% of average annual net
assets over $1 billion.     
   
 Oppenheimer or its affiliates will pay a fee to Chubb Colonial equal, on an
annualized basis, to 0.10% of the aggregate net assets of the Bond Fund and
0.15% for the Strategic Bond Fund attributable to contracts offered by Chubb
Colonial or its affiliates. Such fees will not be payable by the Funds, their
shareholders or by the Contract holders.     
   
 The investment objectives of each Portfolio of the Oppenheimer Variable
Account Funds in which Separate Account B invests are set forth below:     
   
 Bond Fund: primarily seeks a high level of current income from investment in
high yield fixed-income securities rated "Baa" or better by Moody's or "BBB"
or better by Standard & Poor's. Secondarily, this Fund seeks capital growth
when consistent with its primary objective.     
 
                                      15
<PAGE>
 
   
 Strategic Bond Fund: seeks a high level of current income principally derived
from interest on debt securities and seeks to enhance such income by writing
covered call options on debt securities.     
       
 There can be no assurance that any of the Portfolios will achieve its stated
objectives. The specialized nature of each Portfolio gives rise to significant
differences in the relative investment potential and market and financial
risks of each Portfolio. Policyowners should consider the unique features of
each Portfolio before investing in any Portfolio. For more detailed
information concerning each Portfolio, including a description of the
investment risks, reference is made to the prospectuses for the Funds which
accompanies this Prospectus, or the Statements of Additional Information for
the Funds, available on request.
 
 Separate Account B will purchase shares of the Funds at net asset value in
connection with premium payments allocated to the divisions in accordance with
the policyowner's directions and will redeem shares of the Funds to process
transfers, policy loans, surrenders or withdrawals and generally to meet
contract obligations or make adjustments in reserves. The Funds will sell and
redeem its shares at net asset value as of the Date of Receipt by Separate
Account B of premium payments or notifications by a policyowner.
 
                                      16
<PAGE>
 
                                  THE POLICY
 
 General. The Policy is designed to provide the policyowner with lifetime
insurance protection and flexibility in connection with the amount and
frequency of premium payments and the level of life insurance proceeds payable
under the Policy. The policyowner is not required to pay scheduled premiums to
keep the Policy in force but may, subject to certain limitations, vary the
frequency and amount of premium payments. Moreover, subject to certain
limitations, the Policy allows a policyowner to adjust the level of life
insurance payable under the Policy without having to purchase a new Policy by
increasing or decreasing the Specified Amount. Thus, as insurance needs or
financial conditions change, the policyowner has the flexibility to adjust
life insurance proceeds and vary the premium payments. Death benefits are
payable under two options as described in "POLICY BENEFITS AND RIGHTS--Death
Benefits".
 
 To purchase a Policy, a completed application must be submitted to Chubb
Colonial through the agent selling the Policy. Chubb Colonial will generally
not issue Policies to insure persons older than age 80. Applicants for
insurance must furnish satisfactory evidence of insurability. Distinctions
between smokers and nonsmokers are only made for Insureds age 15 and over. The
minimum Specified Amount for a Policy at issue is $25,000. Chubb Colonial
reserves the right to revise its rules from time to time to specify a
different minimum Specified Amount at issue. If the Specified Amount applied
for plus all other insurance in force which is underwritten by Chubb Colonial
or its affiliates exceeds $1,250,000, Chubb Colonial will reinsure all or a
portion of the Policy. Acceptance of an application or revocation of a Policy
during the contestable period is subject to Chubb Colonial's insurance
underwriting rules and Chubb Colonial may, in its sole discretion, reject any
application or related premium for any good reason or contest a Policy.
 
 Payment of Premiums. Premiums must be paid to Chubb Colonial or through an
authorized agent of Chubb Colonial for forwarding to Chubb Colonial. In
addition, Chubb Colonial has instituted administrative procedures whereby
premium payments in response to billing notices are sent directly to Chubb
Colonial's bank. Unlike traditional insurance contracts, there is no fixed
schedule of premium payments on a Policy either as to the amount or the timing
of the payment. A policyowner may determine, within specified limits, his or
her own premium payment schedule. These limits will be set forth by Chubb
Colonial and will include a minimum initial premium payment sufficient to keep
the policy in force for three months and may also include limits on the total
amount and frequency of payments in each policy year. No premium payment may
be less than $25. In order to help the policyowner obtain the insurance
benefits desired, a Planned Periodic Premium and Premium Frequency will be
stated in each Policy. This premium will usually be based upon the
policyowner's insurance needs, the policyowner's financial abilities and the
current financial climate, in general, as well as on the Specified Amount of
the Policy and the Insured's age, sex and risk class. The policyowner is not
required to pay such premiums and failure to make any premium payment will not
necessarily result in lapse of the Policy, provided the Policy's cash value,
less policy debt, if any, is sufficient to pay monthly deductions. Conversely,
adherence to the schedule of Planned Periodic Premiums will not assure that
the Policy will remain in force. See "THE POLICY--Policy Lapse."
 
 Premium Limitations. In no event can the total of all premiums paid, both
scheduled and unscheduled, exceed the current maximum premium limitations
required by the Code. The premium limitations under the Policy are imposed in
order to comply with present requirements to obtain favorable federal income
tax treatment of the Policy and its death benefit. If at any time a premium is
paid which would result in total premiums exceeding the current maximum
premium limitation, Chubb Colonial will only accept that portion of the
premium which will make total premiums equal the maximum. Any part of the
premium in excess of that amount will be returned and no further premiums will
be accepted until allowed by the current maximum premium limitations required
by the Code. Also, if, at any time during the year, a premium has been paid
which would result in the Policy being deemed a modified endowment contract,
Chubb Colonial will so notify the policyowner and allow the policyowner to
request a refund of the excess premium, or other action, in order to avoid
having the Policy be deemed a modified endowment contract. A policyowner,
however, may choose to have the Policy be deemed a modified endowment
contract, and, in that case, Chubb Colonial will not refund the premiums. See
"FEDERAL TAX MATTERS--Policy Proceeds." Premium payments less than the minimum
amount of $25 will be returned to the policyowner.
 
 Allocation of Premiums. Premium payments, net of the premium tax charge, plus
interest earned prior to the Allocation Date, will be allocated on the
Allocation Date among the General Account and the divisions of Separate
Account B in accordance with the directions of the policyowner, as contained
in the application. Prior to the Allocation Date the initial net premium will
be deposited in Chubb Colonial's General Account. Any other premiums received
prior to the Allocation Date will also be deposited in the General Account.
The minimum percentage of any net premium payment allocated to any division or
the General Account is 5%. Allocation percentages must be in whole numbers
only; no fractional percentages
 
                                      17
<PAGE>
 
will be accepted. The policyowner may change his or her allocation of future
premium payments among the General Account and the divisions of Separate
Account B by written notice to Chubb Colonial or by telephone, provided that
the proper telephone authorization is on file with Chubb Colonial, without
payment of any fee or penalty. See "THE POLICY--Telephone Transfers, Loans and
Reallocations".
 
 The allocation of each net premium payment to a division will be determined
first by multiplying the net premium payment by the fraction to be allocated
to each division as the policyowner directs to determine the portion to be
invested in the division. Each portion to be invested in each division is then
divided by the unit value of that particular division. The unit value of each
division will vary to reflect the investment performance of the applicable
underlying Portfolio shares. The unit value will be determined on each
valuation date by multiplying the net asset value of the shares of the
underlying Portfolio held by the division on the preceding valuation date by
the net investment factor for that division for the valuation period then
ended. The net investment factor for each of the divisions is equal to (i) the
asset value per share of the corresponding Portfolio at the end of the
preceding valuation period plus the per share amount of any investment income
and capital gains, realized or unrealized, credited to such assets in the
valuation period for which the net investment factor is being determined, less
capital losses, realized or unrealized, charged against such assets during
such valuation period and less any amount set aside by Chubb Colonial during
the period as a reserve for taxes attributable to the operation or maintenance
of each division, (ii) divided by the asset value per share of the
corresponding Portfolio at the end of the preceding valuation period and (iii)
less a charge not to exceed .0024657% on a daily basis (.90% on an annual
basis) for policy years one through ten and .0017808% on a daily basis (.65%
on an annual basis) for policy years eleven and thereafter of the value of the
division to compensate Chubb Colonial for assumption of certain mortality and
expense risks. See "CALCULATION OF ACCUMULATION VALUE--Unit Values".
Applicants should refer to the prospectus for the Fund which accompanies this
Prospectus for a description of how the assets of each Portfolio are valued
since that determination directly affects the unit value of a division and,
therefore, the accumulation value of a Policy.
 
 All valuations in connection with the Policy, e.g., with respect to
determining cash value in connection with policy loans or withdrawals, with
respect to determining accumulation value in connection with transfers or
payment of death benefits, and with respect to determining the value of a
division to be credited to a Policy with each net premium payment, will be
made on the Date of Receipt of the premium or the request for payment, loan,
withdrawal or transfer if such date is a valuation date; otherwise, such
determination will be made on the next succeeding day which is a valuation
date. The date of receipt of a premium payment sent directly to Chubb
Colonial's bank pursuant to a billing notice will be the date the payment is
received at the bank and the value of any division to which the payment is
allocated will be determined as of such date provided such date is a valuation
date; otherwise, such determination will be made on the next succeeding day
which is a valuation date.
 
 Transfers. Accumulation value may be transferred between the General Account
and the divisions of Separate Account B and among the divisions of Separate
Account B. Transfer requests may be made in writing or by telephone with
appropriate telephone authorization on file with Chubb Colonial. See "THE
POLICY--Telephone Transfers, Loans and Reallocations". The total amount
transferred each time must be at least $250 unless a lesser amount constitutes
the entire accumulation value in the General Account or in a division.
Accumulation value transferred from one division or from the General Account
into more than one division, and/or into the General Account, counts as one
transfer. Similarly, transferring accumulation value from more than one
division, and/or the General Account, into one other division or the General
Account, counts as one transfer.
 
 A transfer charge to cover administrative costs will be imposed each time
amounts are transferred and will be deducted on a pro-rata basis from the
division or divisions of Separate Account B or the General Account into which
the amount is transferred. However, no transfer charge will be imposed on the
transfer of the initial net premium payments, plus interest earned, from the
General Account to the divisions of Separate Account B on the allocation date
or on loan repayments. In addition, Chubb Colonial currently permits 12
transfers per policy year without imposing a transfer charge. The charge will
be the lesser of $25 or 10% of the amount transferred. Currently, a
policyowner may make up to 20 transfers per policy year.
 
 As long as any portion of the Policy's accumulation value is allocated to a
division of Separate Account B, the Policy's accumulation value and cash value
will reflect the investment experience of the chosen division(s) of Separate
Account B. The death benefit may also reflect the experience of the chosen
division(s) of Separate Account B.
 
 At any time the policyowner may transfer 100% of the Policy's accumulation
value to the General Account and elect to have all future premium payments
allocated to the General Account. While 100% of the Policy's accumulation
value and all
 
                                      18
<PAGE>
 
future premium payments are allocated to the General Account, the minimum
period the Policy will be in force will be fixed and guaranteed. The minimum
period will depend on the amount of accumulation value, the Specified Amount,
the sex, the attained age, and rating class of the Insured. The minimum period
will decrease if the policyowner subsequently elects to increase the Specified
Amount, elects to surrender the Policy, or elects to make a withdrawal. The
minimum period will increase if the policyowner elects to decrease the
Specified Amount, additional premium payments are received, or Chubb Colonial
credits a higher interest rate or charges a lower cost of insurance rate than
those guaranteed for the General Account.
 
 No transfer charge will be imposed for a transfer of all accumulation value
in Separate Account B to the General Account. However, any transfer from the
General Account to the division(s) of Separate Account B will be subject to
the transfer charge, unless it is one of the first 12 transfers in a policy
year and except for the transfer of the initial net premium payments, plus
interest earned, from the General Account and loan repayments.
 
 Chubb Colonial reserves the right to refuse to accept or to place certain
restrictions on transfers made by third-party agents acting on behalf of
multiple policyowners or made pursuant to market timing services when Chubb
Colonial determines, in its sole discretion, that such transfers will be
detrimental to the Portfolios and the policyowners as a whole. Such transfers
may cause increased trading and transaction costs, disruption of planned
investment strategies, forced and unplanned portfolio turnover, and lost
opportunity costs, and may subject the Portfolio to large asset swings that
diminishes the Portfolio's ability to provide maximum investment return to all
policyowners.
   
 A feature called Dollar Cost Averaging is available to policyowners under
which a policyowner deposits an amount, subject to a minimum of $3,000, in the
Money Market Division or the General Account and elects to have a specified
dollar amount (the "Periodic Transfer Amount") automatically transferred to
one or more of the divisions on a monthly, quarterly, or semi-annual basis.
This feature allows policyowners to systematically invest in the divisions at
various prices which may be higher or lower than the price a policyowner would
pay when investing the entire amount at one time and at one price. Each
Periodic Transfer Amount is subject to a minimum of $250. A minimum of 5% of
the Periodic Transfer Amount must be transferred to any specified division.
These amounts are subject to change at Chubb Colonial's discretion. If a
transfer would reduce accumulation value in the Money Market Division or the
General Account to less than the Periodic Transfer Amount, Chubb Colonial
reserves the right to include such remaining accumulation value in the amount
transferred.     
   
 Dollar Cost Averaging will continue until the policyowner gives notification
of cancellation of the feature. Any amounts deposited into the Repository
Account will be transferred. Dollar Cost Averaging is currently available at
no charge to policyowners. Although Chubb Colonial reserves the right to
assess a charge, no greater than cost and with 30 days advance notice to
policyowners, it has no present intention to do so.     
 
 An Automatic Portfolio Re-Balancing feature is also available to
policyowners. This feature provides a method for re-establishing fixed
proportions between various types of investments on a systematic basis. Under
this feature, the allocation between divisions and the General Account will be
automatically readjusted to the desired allocation, subject to a minimum of 5%
per division or General Account, on a quarterly, semi-annual or annual basis.
Although Chubb Colonial reserves the right to assess a charge no greater than
cost and with 30 days advance notice to the policyowners for this feature, it
has no present intention to do so.
 
 A policyowner may not elect to have Dollar Cost Averaging and Automatic
Portfolio Re-Balancing at the same time. Transfers and adjustments pursuant to
these features will occur on a Policy's monthly anniversary date in the month
in which the transaction is to take place or the next succeeding business day
if the monthly anniversary date falls on a holiday or a weekend. The
applicable authorization form must be on file at Chubb Colonial before either
feature may begin. Neither feature guarantees profits nor protects against
losses. Transfers under these features do not count towards the twelve free
transfers or the twenty transfers currently allowed per year. Chubb Colonial
reserves the right to modify the terms and conditions of these features upon
30 days advance notice to policyowners.
 
 Telephone Transfers, Loans and Reallocations. Policyowners and their
authorized representatives may request by telephone transfers of accumulation
value or reallocation of premiums (including allocation changes pursuant to
existing Dollar Cost Averaging and Automatic Portfolio Re-Balancing programs),
provided that the appropriate authorization form is on file with Chubb
Colonial. Chubb Colonial may also, in its discretion, permit loans to be made
by telephone, provided that the proper authorization form is on file with
Chubb Colonial. Only the Policyowner may request loans by telephone.
 
                                      19
<PAGE>
 
   
Procedures have been established that are reasonably designed to reduce the
risk of unauthorized telephone transfers, loan requests or allocation changes.
These procedures include requiring personal identification information at the
time of such request for verification purposes, such as the policyowner's
social security number and date of birth. In addition, Chubb Colonial also
tape records calls and provides written confirmations to policyowners.
Notwithstanding these procedures, there still exists some risk. Neither Chubb
Colonial, Chubb Securities Corporation, nor any of their affiliates are liable
for any loss resulting from unauthorized telephone transfers, loan requests or
premium allocation changes of its procedures have been followed, and a
policyowner bears the risk of loss in such situation.     
 
 Policy Lapse. Failure to make a premium payment on a Policy will not
necessarily cause the Policy to lapse. The duration of a Policy depends upon
its cash value. The Policy will remain in force so long as the cash value,
less any outstanding policy debt, is sufficient to pay the monthly deduction.
In the event the cash value, less any outstanding policy debt, is insufficient
to pay the monthly deduction, the policyowner will be given a sixty-one day
period ("grace period") within which to make a premium payment to avoid lapse.
The premium required to avoid lapse must be sufficient in amount, after the
deduction of the premium tax charge, to cover the monthly deductions for at
least three policy months. This required premium will be set forth in a
written notice which Chubb Colonial will send to the policyowner at the
beginning of the grace period. The Policy will continue in force through the
grace period, but if no payment is forthcoming, the Policy will terminate
without value at the end of the grace period. If the Insured under the Policy
dies during the grace period, the death benefit payable under the Policy will
be reduced by the amount of the monthly deduction due and unpaid and the
amount of any outstanding policy debt. In addition, if the cash value of the
Policy at any time should decrease so the aggregate amount of an outstanding
policy debt secured by the Policy exceeds the cash value shown in the Policy
and an additional payment is not made within sixty-one days of notification by
Chubb Colonial, the Policy will lapse.
 
 Reinstatement. If the Policy lapses, the policyowner may reinstate the
Policy. The terms of the original contract will apply upon reinstatement. The
accumulation value, before payment of the required reinstatement premium, will
equal the accumulation value on the date of termination. The policy year on
reinstatement will be measured from the policy date. An application for
reinstatement may be made any time within five years of lapse, but
satisfactory proof of insurability and payment of a reinstatement premium is
required. The reinstatement premium, after deduction of the premium tax
charge, must be sufficient to cover monthly deductions for three policy months
following the effective date of reinstatement. If a loan was outstanding at
the time of lapse, Chubb Colonial will require, at the election of the
policyowner, repayment or reinstatement of the loan before permitting
reinstatement of the Policy. The effective date will be the date of approval
of the reinstatement application.
 
 Policy "Free Look". The policyowner has a limited right to return a Policy
for cancellation and a full refund of all premiums paid. Chubb Colonial will
cancel the Policy if it is returned by mail or personal delivery to Chubb
Colonial or to the agent who sold the Policy, within 20 days after the
delivery of the Policy to the policyowner, within 45 days of the date of the
execution of the application for insurance, or within 20 days after mailing or
personal delivery of a Notice of the Right of Withdrawal, whichever is later.
Chubb Colonial will return to the policyowner within seven days all payments
received on the Policy. Prior to the allocation date the initial net premium
will be deposited in Chubb Colonial's General Account; Chubb Colonial will
retain any interest earned if the "free look" right is exercised.
 
                            CHARGES AND DEDUCTIONS
 
 Premium Charges. Upon receipt of each premium payment and before allocation
of the payment among the General Account and divisions of Separate Account B,
Chubb Colonial will deduct a premium tax charge of 2.0% to compensate Chubb
Colonial for state premium, franchise and other local taxes imposed by New
York and local jurisdictions. The actual taxes imposed on Chubb Colonial may
fall between 1.7% and 2.5% of premiums received. As a result, the 2.0% charge
may at times be higher or lower than the actual tax incurred by Chubb
Colonial. Chubb Colonial reserves the right to increase this charge to
policyowners up to a maximum of 2.5%. Chubb Colonial does not expect to
receive a profit as a result of this charge.
 
 Monthly Deduction. On the first day of each policy month beginning on the
policy date, Chubb Colonial will deduct from the accumulation value of a
Policy an amount to cover certain charges and expenses incurred in connection
with the Policy. The monthly deduction is intended to compensate Chubb
Colonial for underwriting and start-up expenses incurred in
 
                                      20
<PAGE>
 
   
connection with the issuance of a Policy, certain administrative expenses, the
cost of insurance for the Policy and any optional benefits added by rider. At
the option of the policyowner the amount deducted can be deducted from any one
of the divisions of Separate Account B or pro-rata from each of the divisions
and the General Account. If the policyowner does not designate one division,
then the monthly deduction will be deducted pro-rata from each of the
divisions and the General Account.     
 
 The amount of the monthly deduction is equal to (i) the cost of insurance for
the Policy, as described below, and the cost of additional benefits provided
by rider, plus (ii) a monthly administrative charge of $6.00. The monthly
administrative charge may not be increased.
 
 The cost of insurance for the Insured is determined on a monthly basis, and
is determined separately for the initial Specified Amount and each subsequent
increase in the Specified Amount. The monthly current cost of insurance rate
is based on the sex, issue age, policy year, rating class of the Insured, and
the Specified Amount of the Policy. If we assume two Insureds differ only with
regard to one of the above bases, the effect of each of these bases on their
monthly cost of insurance rates would be as follows:
 
 Sex: The cost of insurance rates for males will be greater than or equal to
those for females.
 
 Issue Age: The cost of insurance rate for the younger Insured will be less
than or equal to that for the older Insured.
 
 Policy Year: The current cost of insurance rate will increase as the policy
year increases. For two Insureds with the same sex, rating class, and attained
age the cost of insurance rate for the Insured with the younger issue age will
never exceed, and in some cases will be less than that for the Insured with
the older issue age.
 
 Rating Class: The cost of insurance rates for nonsmokers will be less than or
equal to those for smokers. Cost of insurance rates may also differ due to the
Insured's medical condition, occupation, or avocation.
 
 Specified Amount: The current cost of insurance rates will vary by Specified
Amount, with different rates applying to Specified Amounts under $100,000,
between $100,000 and $249,999, between $250,000 and $999,999 and $1,000,000
and over. Current cost of insurance rates are highest for Specified Amounts
under $100,000, decreasing for each successive Specified Amount range as noted
above.
 
 The cost of insurance is calculated as (i) multiplied by the result of (ii)
minus (iii) where:
 
  (i) is the cost of insurance rate as described in the Cost of Insurance
 Rates provision contained in the Policy.
 
  (ii) is the death benefit at the beginning of the policy month divided by
 1.0036748, to arrive at the proper values for the beginning of the month
 assuming the guaranteed interest rate of 4.5% that is applicable to the
 General Account portion of the Policy; and
 
  (iii) is the accumulation value at the beginning of the policy month.
 
 If the corridor percentage is applicable, the death benefit used in the
foregoing calculation will reflect the corridor percentage.
 
 The monthly cost of the insurance rate will be determined by Chubb Colonial
based upon expectations as to future mortality experience, but can never
exceed the rates shown in the table of Monthly Guaranteed Cost of Insurance
Rates set forth in the Policy. Such guaranteed maximum rates are based on the
Commissioner's 1980 Standard Ordinary Mortality Table.
 
 Risk Charge. Chubb Colonial will also assess a charge on a daily basis
against each division of Separate Account B equal to .0024657% on a daily
basis (.90% on an annual basis) for policy years one through ten and .0017808%
on a daily basis (.65% on an annual basis) for policy years eleven and
thereafter of the value of the division to compensate Chubb Colonial for its
assumption of certain mortality and expense risks in connection with the
Policy. Specifically, Chubb Colonial bears the risk that the total amount of
death benefit payable under the Policy will be greater than anticipated and
Chubb Colonial also assumes the risk that the actual cost incurred by it to
administer the Policy will not be covered by charges assessed under the
Policy.
 
 Surrender Charge. Upon surrender or withdrawal, Chubb Colonial will assess a
surrender charge. The surrender charge for the initial Specified Amount is
determined by multiplying a surrender factor by the lesser of (1) the premiums
actually received in policy year one; or (2) the "Guideline Annual Premium" as
defined in the rules and regulations under the 1940 Act. The surrender factor
depends on the length of time the policy has been in force, as follows:

</TABLE>
 
 Paying less premium in policy year one generally will have the effect of
reducing the surrender charge. However, depending on investment experience,
paying less premium in policy year one may result in an increase in cost of
insurance charges, a reduction in accumulation value and an increased risk
that the Policy will lapse.
 
 An additional surrender charge will be assessed for any increase in the
Specified Amount, other than an increase caused by a change from death benefit
Option I to death benefit Option II. The additional surrender charge is
determined by multiplying a surrender factor by the lesser of (1) or (2),
where:
 
  (1) is A times B divided by C, where:
 
    A is the amount of the increase in the Specified Amount
 
    B is the sum of the cash value just prior to the increase in the
   Specified Amount and the total premiums received in the twelve months just
   following the increase in the Specified Amount
 
    C is the Specified Amount in effect after the increase in the Specified
   Amount
 
  (2) is the "Guideline Annual Premium" for the increase at the attained age
 of the Insured on the effective date of the increase in the Specified Amount.
 
 The surrender factor depends on the length of time the increase has been in
force, as follows:

 The surrender charge in effect at any time is the sum of the surrender charge
for the initial Specified Amount plus the surrender charge for any increase in
the Specified Amount. If the Specified Amount is decreased, the surrender
charge will not decrease.
 
 For a withdrawal, the charge will be proportionately the same as for
surrenders. The charge will be calculated by dividing (a) by (b) and
multiplying the result by (c) where:
 
  (a) is the amount of the cash value withdrawn
 
  (b) is the cash value; and
 
  (c) is the amount of the surrender charge on a surrender.
 
 The surrender charge helps to compensate Chubb Colonial for the cost of
selling the Policy. The cost includes advertising and the printing of the
Prospectus and sales literature. Also, Chubb Colonial reimburses Chubb
Securities Corporation for all commissions Chubb Securities Corporation pays
to agents. Chubb Colonial expects to recover total sales expenses of the
Policy over the life of the Policy. To the extent sales expenses in any one
policy year are not recovered by the sales charge, Chubb Colonial will cover
such expenses from its surplus, which may include profits, if any, from the
mortality and expense risk charge.
 
 Administrative Fees. An administrative fee equal to the lesser of $25 or 10%
of the amount of the transfer is imposed for each transfer among the divisions
of Separate Account B or the General Account, after the first 12 transfers in
a policy
 
                                      22
<PAGE>
 
year and except for the transfer of the initial net premium payments, plus
interest, from the General Account on the allocation date and loan repayments.
For withdrawals, an administrative fee equal to the lesser of $25 or 2% of the
amount withdrawn will be charged. After the policy date, a policyowner may
request illustrations of benefits and values. Such illustrations are currently
available to policyowners at no charge. Although Chubb Life reserves the right
to assess a charge, no greater than $25 and with advance notice to
policyowners, it has no present intention to do so. All administrative fees,
including those which are part of the monthly deduction, are no greater than
the anticipated expenses of providing such services.
 
 Other Charges. Chubb Colonial also reserves the right to charge the assets of
each division to provide for any income taxes or other taxes payable by Chubb
Colonial on the assets attributable to that division. An investment advisory
fee is also imposed against the assets of each Portfolio for services provided
by the Fund's investment manager and sub-investment managers.
 
                          POLICY BENEFITS AND RIGHTS
 
 Death Benefits. So long as it remains in force, the Policy provides for the
payment of life insurance proceeds upon the death of the Insured. Proceeds
will be paid to a named beneficiary or contingent beneficiary. One or more
beneficiaries or contingent beneficiaries may be named. Life insurance
proceeds may be paid in a lump sum or under an optional payment plan. (See
"Settlement Options" below.) Proceeds of the Policy will be reduced by any
outstanding policy debt and any due and unpaid charges and increased by any
benefits added by rider. Proceeds that are payable in a lump sum at the death
of the Insured will be increased to include interest as required by applicable
state law. Proceeds will ordinarily be paid within seven days after Chubb
Colonial receives due proof of death. Also see "Optional Insurance Benefits--
Terminal Illness Accelerated Benefit Rider."
 
 Policyowners designate in the initial application one of two death benefit
options offered under the Policy. The amount of life insurance proceeds
payable under a Policy will depend upon the option in effect at the time of
the Insured's death. Option I emphasizes the impact of investment experience
on accumulation value rather than insurance coverage because the Specified
Amount and the death benefit, generally, remain stable. Under Option I, as
accumulation value increases and the death benefit does not increase, the
amount at risk decreases. Thus, the cost of insurance charges are imposed on a
decreasing amount. Option II emphasizes insurance coverage because favorable
investment experience adds to the accumulation value that provides an addition
to the total death benefit. Under Option II, favorable investment experience
does not reduce the amount at risk upon which cost of insurance charges are
based.
 
 Under Option I, life insurance proceeds will be equal to the greater of the
Specified Amount, or the accumulation value of the Policy at the date of death
multiplied by the corridor percentage, as described below. Under Option II,
life insurance proceeds will be the Specified Amount plus the accumulation
value of the Policy on the date of death. Under Option II, the death benefit
can never be less than the accumulation value on the date of death multiplied
by the corridor percentage.
 
 The corridor percentage depends upon the attained age of the Insured on the
date of death. The corridor percentage for each age is set forth in the
following table:

 The death benefit option in effect may be changed by sending Chubb Colonial a
written request for change. If the death benefit option is changed from Option
II to Option 1, the Specified Amount will be increased by the Policy's
accumulation value; the effective date of the change will be the date of Chubb
Colonial's receipt of such request for change. Conversely, if the death
benefit option is changed from Option I to Option II, the Specified Amount
will be decreased by the Policy's accumulation value; the effective date of
the change will be the date of Chubb Colonial's underwriting approval of such
request for change. Evidence of insurability satisfactory to Chubb Colonial
will be required on a change from Option I to Option II. A change in the
benefit option may not be made if it would result in a Specified Amount which
is less than the minimum Specified Amount of $25,000. A change in benefit
options will affect the cost of insurance.
 
 The policyowner, under attained age 85, may adjust the existing insurance
coverage by increasing the Specified Amount at any time after the Policy has
been issued. After a Policy has been in force for one year, the policyowner,
under attained age 85, may adjust the existing insurance coverage by
decreasing the Specified Amount. The increase or decrease must be at least
$25,000. To make a change, the policyowner must send a written request and the
Policy to Chubb Colonial. Any change in the Specified Amount will affect a
policyowner's cost of insurance charge. An increase in the Specified Amount
will affect the determination of the amount available for a Type A loan;
decreases in the Specified Amount will not have any such effect. Any increase
in the Specified Amount will become effective on the monthly anniversary date
after the Date of Receipt for the request. Any decrease in Specified Amount
will first apply to coverage provided by the most recent Specified Amount
increase, then to the next most recent increases successively and finally to
the coverage under the original application. By applying decreases in this
manner, savings, generally, may be realized by a policyowner since additional
costs and limitations associated with increases in Specified Amounts would be
eliminated first. To apply for an increase in the Specified Amount, a
supplemental application must be completed and evidence satisfactory to Chubb
Colonial that the Insured is insurable must be submitted. Any approved
increase in the Specified Amount will become effective on the date shown in
the Supplemental Policy Specifications Page. Such increase will not become
effective, however, if the Policy's cash value is insufficient to cover the
deduction for the cost of the increased insurance for the policy month
following the increase. Such an increase may require a payment or future
increased Planned Periodic Premiums. Policyowners should consult their
insurance advisers regarding the availability of the Primary Insured Term
Rider described below as an alternative way of increasing coverage. See
"CHARGES AND DEDUCTIONS."
 
 Guaranteed Death Benefit. The policyowner may add a Guaranteed Death Benefit
Rider to the Policy under which the death benefit is guaranteed to never be
less than the Specified Amount provided that a cumulative minimum premium
requirement is met. The premium requirement is based on issue age, sex,
smoking status, underwriting class, Specified Amount and death benefit option.
If the Specified Amount is increased, an additional premium, based on attained
age, will be required for such increase. There is a monthly charge for this
rider. See "Optional Insurance Benefits."
 
 Combined Requests. Policyowners may combine requests for changes in the
Specified Amount and the death benefit option and requests for withdrawals.
The requirements and limitations that apply to each change will apply to the
combined transactions, including any required evidence of insurability,
Specified Amount and premium limitations, effectiveness on the monthly
anniversary date following the Date of Receipt of the request, and the
sufficiency of cash value to keep the Policy in force for the month following
the transaction.
 
 The effect of a combined transaction on the cost of insurance, the amount of
the death benefit proceeds and the premium limitations will be the net result
of such effects for each such transaction considered separately. For example,
combining a request for a withdrawal under Option I with a request for an
increase in the Specified Amount will result in a greater amount at risk, an
increase in the cost of insurance and a requirement of evidence of
insurability. Policyowners should consider the net result of a combined
transaction in light of insurance needs, financial circumstances and tax
consequences.
 
 Maturity of the Policy. As long as the Policy remains in force, Chubb
Colonial will pay the Policy's cash value, less outstanding policy debt, if
any, on the maturity date. Benefits at maturity may be paid in a lump sum or
under an optional payment plan. The maturity date is the date shown in the
Policy. To change the maturity date, a written request and the Policy must be
sent to Chubb Colonial at its service center. The Date of Receipt for any
request must be before the maturity date then in effect. The requested
maturity date must be (i) on a policy anniversary, (ii) at least one year from
the Date of Receipt of the request, (iii) after the tenth policy year and (iv)
on or before the policy anniversary nearest to the Insured's 95th birthday.
 
 Optional Insurance Benefits. Subject to certain requirements, one or more of
the following optional insurance benefits may be added to a Policy by rider.
More detailed information concerning such riders may be obtained from the
agent selling the Policy. Additional riders, developed after the effective
date of this Prospectus, may also be available as optional insurance
 
                                      24
<PAGE>
 
benefits to the Policy. The agent selling the Policy should be consulted
regarding the availability of any such additional riders. The cost of any
optional insurance benefits will be deducted as part of the monthly deduction.
See "CHARGES AND DEDUCTIONS."
   
 (a) Children's Term Insurance Rider. This benefit provides increments of
level term insurance on the Insured's children, as defined in the rider. Under
the terms of this rider, Chubb Life will pay the death benefit set forth in
the rider to the proper beneficiary upon receipt of proof of death of the
insured child. Upon receipt of proof of death of the Insured, the Children's
Term Insurance Rider will continue in force under its terms without additional
monthly charges.     
   
 (b) Guaranteed Insurability Rider. This benefit provides that the Insured can
purchase additional insurance at certain future dates without evidence of
insurability. Under the terms of the rider, the Insured may, without evidence
of insurability, increase the Specified Amount of the Policy on an option
date, as defined in the rider.     
   
 (c) Accidental Death Benefit Rider. This benefit provides additional
insurance if the Insured's death results from an accident, as defined in the
rider.     
   
 (d) Exchange of Insured Rider. This benefit provides that the Policy may be
exchanged for a reissued policy on the life of a substitute insured, subject
to the conditions stated in the rider. See "FEDERAL TAX MATTERS."     
   
 (e) Terminal Illness Accelerated Benefit Rider. This benefit advances up to
50% of a policy's eligible death benefit, subject to a $250,000 maximum per
insured, if it is medically determined that the insured is terminally ill and
has a life expectancy of six months or less, as defined in the rider. Upon the
payment of the accelerated benefit payment, the amount of the death benefit,
the Specified Amount, the cash value and the accumulation value are reduced by
the same ratio as the requested portion of the death benefit bears to the
original death benefit. Such reduction will be allocated among the General
Account and the divisions of Separate Account B on a pro rata basis. While
this benefit is offered at no additional premium cost or surrender charge, an
actuarial discount as described in the rider, which reflects the early payment
of amounts held under the Policy, will be deducted from the requested portion
of the death benefit. In addition, Chubb Colonial imposes an administrative
expense charge not to exceed the lesser of the actual cost of administering
the exercise of the rider or $300. Chubb Colonial will deduct from the
requested portion of the death benefit a prorated portion of any outstanding
policy loans and any premiums which are unpaid within the grace period. Cost
of insurance charges are adjusted to reflect the reduction in the death
benefit. Future charges under the Policy will depend on whether a Waiver of
Premium Disability Rider is in force. See "FEDERAL TAX MATTERS."     
   
 (f) Other Insured Term Rider. This benefit provides increments of level term
insurance on the life of an insured other than the Insured under the Policy.
       
 (g) Primary Insured Term Rider. This benefit provides increments of level
term insurance on the life of the Insured under the terms set forth in the
rider. See "FEDERAL TAX MATTERS".     
   
 (h) Waiver of Specified Premium Rider. This benefit provides for the payment
by Chubb Colonial of a specified monthly premium into the Policy while the
Insured is totally disabled, as defined in the rider; the minimum monthly
benefit will be at least enough to maintain the base policy and all
supplementary coverages in force.     
   
 (i) Guaranteed Death Benefit Rider. This benefit guarantees that the Policy
will stay in force with a death benefit equal to the Specified Amount, even if
the cash value less policy debt is not sufficient to pay the monthly
deduction, provided that cumulative premiums paid, less loans and withdrawals,
are greater than or equal to the guaranteed death benefit premium multiplied
by the number of months the policy has been in force. This cumulative premium
requirement must be met at all times for the rider to stay in force. A monthly
charge of $.01 per $1,000 of Specified Amount will be deducted from the
Policy's accumulation value.     
 
 Settlement Options. In addition to a lump sum payment of benefits under the
Policy, any proceeds to be paid under the Policy may be paid in any of four
methods. A settlement option may be designated by notifying Chubb Colonial in
writing. A lump sum payment of proceeds under the Policy will be made if a
settlement option is not designated. Any amount left with Chubb Colonial for
payment under an optional payment plan will be transferred to the account of
the beneficiary in the General Account on the date Chubb Colonial receives
written instructions. During the life of the Insured, the policyowner may
select a plan. If a payment plan has not been chosen at the Insured's death, a
beneficiary can choose a plan. If a beneficiary is changed, the payment plan
selection will no longer be in effect unless the policyowner requests that it
continue. An option may be elected only if the amount of the proceeds is
$2,000 or more. Chubb Colonial reserves the right to change
 
                                      25
<PAGE>
 
the interval of payments to 3, 6 or 12 months, if necessary, to increase the
guaranteed payments to at least $20 each.
 
 OPTION A.
 
 Installments of a specified amount. Payments of an agreed amount to be made
each month until the proceeds and interest are exhausted.
 
 OPTION B.
 
 Installments for a specified period. Payments to be made each month for an
agreed number of years.
 
 OPTION C.
 
 Life income. Payments to be made each month for the lifetime of the payee. It
is guaranteed that payments will be made for a minimum of 10, 15 or 20 years,
as agreed upon. No election will default to payments made for 20 years. Where
there is a payment of the same amount at some ages for different periods
certain, it will be assumed that the longest period certain which could have
been elected for such age and amount was the period certain actually chosen.
 
 OPTION D.
 
 Interest. Payment of interest on the proceeds held by Chubb Colonial
calculated at the compound rate of 3% per year. Interest payments will be made
at 12, 6, 3 or 1 month intervals, as agreed upon.
 
 The interest rate for Options A, B, and D will not be less than 3% per year.
The interest rate for Option C will not be less than 2 1/2% per year. Interest
in addition to that stated may be paid or credited from time to time under any
option, but only in the sole discretion of Chubb Colonial.
 
 Unless otherwise stated in the election of an option, the payee of policy
benefits shall have the right to receive the withdrawal value under that
option. For Options A and D, the withdrawal value shall be any unpaid balance
of proceeds plus accrued interest. For Option B, the withdrawal value shall be
the commuted value of the remaining payments. Such value will be calculated on
the same basis as the original payments. For Option C, the withdrawal value
will be the commuted value of the remaining payments. Such value will be
calculated on the same basis as the original payments. To receive this value,
the payee must submit evidence of insurability acceptable to Chubb Colonial.
Otherwise, the withdrawal value shall be the commuted value of any remaining
guaranteed payments. If the payee should be alive at the end of the guaranteed
period, the payment will be resumed on that date. The payment will then
continue for the lifetime of the payee.
 
 If a payee of policy benefits dies before the proceeds are exhausted or the
prescribed payments made, a final payment will be made in one sum to the
estate of the last surviving payee. The amount to be paid will be calculated
as described for the applicable option in the Withdrawal Value provision of
the Policy.
 
                       CALCULATION OF ACCUMULATION VALUE
 
 The Policy provides for an accumulation value, which will be determined on a
daily basis. Accumulation value is the sum of the values in the divisions of
Separate Account B plus the value in the General Account. The Policy's
accumulation value in the divisions of Separate Account B is calculated by
units and unit values under the Policies, as described below. The Policy's
accumulation value will reflect a number of factors, including the investment
experience of the divisions of Separate Account B that are invested in the
Portfolios, any additional net premiums paid, any withdrawals, any policy
loans, and any charges assessed in connection with the Policy. Accumulation
values in Separate Account B are not guaranteed as to dollar amount.
 
 On the allocation date, the accumulation value in Separate Account B is the
initial premium payments, reduced by the premium tax charge, plus interest
earned prior to the allocation date, and less the monthly deduction for the
first policy month. On the allocation date, the initial number of units
credited to Separate Account B for the Policy will be established. At the end
of each valuation period thereafter, the accumulation value in a division of
Separate Account B is (i) plus (ii) plus (iii) minus (iv) minus (v) where:
 
   (i) is the accumulation value in the division on the preceding valuation
  date multiplied by the net investment factor, as described below, for the
  current valuation period,
 
   (ii) is any net premium received during the current valuation period which
  is allocated to the division,
 
                                      26
<PAGE>
 
   (iii) is all accumulation values transferred to the division from another
  division or the General Account during the current valuation period,
 
   (iv) is all accumulation values transferred from the division to another
  division or the General Account and accumulation values transferred to
  secure a policy debt during the current valuation period, and
 
   (v) is all withdrawals from the division during the current valuation
  period.
 
 In addition, whenever a valuation period includes the monthly anniversary
date, the accumulation value at the end of such period is reduced by the
portion of the monthly deduction allocated to the division.
 
 The Policy's total accumulation value in Separate Account B equals the sum of
the Policy's accumulation value in each division thereof.
 
 Unit Values. Units are credited to a policyowner upon allocation of net
premiums to a division. Each net premium payment allocated to a division will
increase the number of units in that division. Both full and fractional units
are credited. The number of units and fractional units is determined by
dividing the net premium payment by the unit value of the division to which
the payment has been allocated. The unit value of each division is determined
on each valuation date. The number of units credited will not change because
of subsequent changes in unit value. The dollar value of each division's units
will vary depending upon the investment performance of the corresponding
Portfolio of the Fund.
 
 Certain transactions affect the number of units in a division under a Policy.
Loans, surrenders and withdrawals, withdrawal and transfer fees and charges,
the surrender charge, and monthly deductions involve the redemption of units
and will decrease the number of units. Transfers of accumulation value among
divisions will reduce or increase the number of units in a division, as
appropriate.
 
 The unit value of a division on any valuation date is calculated by
multiplying (1) by (2) where:
 
   (1) is the division's unit value on the previous valuation date; and
 
   (2) is the net investment factor for the valuation period then ended.
 
 The unit value of each division's units on any day other than a valuation
date is the unit value as of the next valuation date and is used for the
purpose of processing transactions.
 
 Net Investment Factor. The net investment factor measures the investment
experience of each division of Separate Account B and is used to determine
changes in unit value from one valuation period to the next valuation period.
The net investment factor for a valuation period is (i) divided by (ii) minus
(iii) where:
 
   (i) is (a) the value of the assets of the division at the end of the
  preceding valuation period, plus (b) the investment income and capital
  gains, realized or unrealized, credited to the assets of the division
  during the valuation period for which the net investment factor is being
  determined, minus (c) capital losses, realized or unrealized, charged
  against those assets during the valuation period, minus (d) any amount
  charged against the division for taxes or any amount set aside during the
  valuation period by Chubb Colonial to provide for taxes attributable to the
  operation or maintenance of that division, and
 
   (ii) is the value of the assets of the division at the end of the
  preceding valuation period, and
 
   (iii) is a charge no greater than .0024657% on a daily basis for policy
  years one through ten and .0017808% on a daily basis for policy years
  eleven and thereafter. This corresponds to .90% on an annual basis for
  policy years one through ten and .65% on an annual basis for policy years
  eleven and thereafter for mortality and expense risks.
 
                              CASH VALUE BENEFITS
 
 So long as it remains in force, the Policy provides for certain benefits
prior to the maturity date. Subject to certain limitations, the policyowner
may at any time obtain cash value by surrendering the Policy or making
withdrawals from the Policy. The cash value equals the accumulation value less
any surrender charge. In addition, the policyowner has certain policy loan
privileges under the Policy.
 
 Surrender Privileges. As long as the Policy is in force, a policyowner may
surrender the Policy or make a withdrawal from the Policy at any time by
sending a written request to Chubb Colonial. See "FEDERAL TAX MATTERS--Policy
Proceeds."
 
                                      27
<PAGE>
 
 The surrender value of the Policy equals the cash value less any outstanding
policy debt. The surrender value will be determined at the end of the
valuation period during which the request for a surrender or withdrawal is
received. Proceeds will generally be paid within seven days of the Date of
Receipt of a request for surrender or withdrawal.
 
 The amount payable upon surrender of the Policy is the surrender value at the
end of the valuation period during which the request is received. The
surrender value may be paid in a lump sum, within seven days of the Date of
Receipt of the request, or under one of the optional payment plans specified
in the Policy. See "POLICY BENEFITS AND RIGHTS--Settlement Options."
 
 A policyowner can obtain a portion of the Policy's cash value by withdrawal
of cash value from the Policy. A withdrawal from a Policy is subject to the
following conditions:
 
   A. The amount withdrawn may not exceed the cash value less any outstanding
  debt.
 
   B. The minimum amount that may be withdrawn is $500.
 
   C. A charge equal to the lesser of $25 or 2% of the amount of the
  withdrawal will be deducted from the amount of each withdrawal.
 
 Withdrawals generally will affect the Policy's accumulation value, cash value
and the life insurance proceeds payable under the Policy. The Policy's cash
value will be reduced by the amount of the withdrawal. The Policy's
accumulation value will be reduced by the amount of the withdrawal plus a pro-
rata surrender charge. Life insurance proceeds payable under the Policy will
generally be reduced by the amount of the withdrawal plus a pro-rata surrender
charge, unless the withdrawal is combined with a request to maintain or
increase the Specified Amount. See "POLICY BENEFITS AND RIGHTS--Combined
Requests."
 
 Under Option I, which provides for life insurance proceeds equal to the
greater of the Specified Amount or the accumulation value of the Policy at the
date of death multiplied by the corridor percentage provided by the Code, the
Specified Amount will be reduced by the amount of the withdrawal plus the pro-
rata surrender charge. The Specified Amount remaining after a withdrawal may
not be less than $10,000. As a result, Chubb Colonial will not effectuate any
withdrawal that would reduce the Specified Amount below this minimum. If
increases in Specified Amount previously have occurred, a withdrawal will
first reduce the Specified Amount of the most recent increase, then the most
recent increases successively, then the coverage under the original
application. If the life insurance proceeds payable under either death benefit
option, both before and after the withdrawal, is the accumulation value
multiplied by the corridor percentage, a withdrawal generally will result in a
reduction in life insurance proceeds equal to the amount paid upon withdrawal,
multiplied by the corridor percentage then in effect.
 
 Under Option II, which provides for life insurance proceeds equal to the
Specified Amount plus accumulation value, a reduction in accumulation value as
a result of a withdrawal will typically result in a dollar per dollar
reduction in the life insurance proceeds payable under the Policy.
 
 A policyowner may allocate a withdrawal among the General Account and the
divisions of Separate Account B. If no such allocation is made, a withdrawal
will be allocated among the General Account and the divisions of Separate
Account B in the same proportion that the accumulation value in the General
Account, less any policy debt, and the accumulation value in each division
bears to the total accumulation value of the Policy, less any policy debt, on
the date of withdrawal. See "FEDERAL TAX MATTERS--Policy Proceeds."
 
 Policy Loans. So long as the Policy remains in force, a policyowner may
borrow money from Chubb Colonial at any time after the first policy
anniversary using the Policy as the only security for the loan. Loans have
priority over the claims of any assignee or any other person. Generally, the
maximum loan amount is 90% of the cash value at the end of the valuation
period during which the loan request is received. The maximum amount which may
be borrowed at any given time is the maximum loan amount reduced by any
outstanding policy debt.
 
 Proceeds of policy loans ordinarily will be disbursed within seven days from
the Date of Receipt of a request for a loan by Chubb Colonial, although
payments may be postponed under certain circumstances. See "OTHER MATTERS--
Postponement of Payments". Chubb Colonial may, in its discretion, permit loans
to be made by telephone if the proper authorization form is on file with Chubb
Colonial. See "THE POLICY--Telephone Transfers, Loans and Reallocations". So
long as the Policy remains in force, the loan may be repaid in whole or in
part without penalty at any time while the Insured is living.
 
                                      28
<PAGE>
 
 When a policy loan is made, a portion of the Policy's accumulation value
sufficient to secure the loan will be transferred to the General Account. A
policy loan removes the proceeds from the investment experience of Separate
Account B which will have a permanent effect on the accumulation value and
death benefit even if the loan is repaid. Any loan interest that is due and
unpaid will also be so transferred. Accumulation value equal to policy debt in
the General Account will accrue interest daily at an annual rate of 6%. The
policyowner may allocate a policy loan among the General Account and the
divisions of Separate Account B. If no such allocation is made the loan will
be allocated among the General Account and divisions of Separate Account B in
the same proportion that the accumulation value in the General Account less
policy debt and the accumulation value in each division bears to the total
accumulation value of the Policy, less policy debt, on the date of the loan.
 
 Chubb Colonial will charge interest on any outstanding policy loan. There are
two types of loans available. A Type A loan is charged the same interest rate
as the interest credited to the amount of accumulation value held in the
General Account to secure loans. The amount available at any time for a Type A
loan equals the maximum loan amount less the DEFRA Guideline Single Premium
("DGSP"), as set forth in the Code, less any outstanding Type A loans. Any
other loans are Type B loans; a Type B loan is charged an interest rate of 8%.
It is possible for one loan request to result in both a Type A and a Type B
loan. A request for a loan will be granted first as a Type A loan, to the
extent available, and then as a Type B loan. Once a policy loan is granted, it
remains a Type A or Type B until it is repaid. Increases in the Specified
Amount will affect the determination of the amount available for a Type A
loan; however, decreases in the Specified Amount will not have any such
effect.
 
 Where applicable, loans are subject to conditions and requirements of the
Employee Retirement Income Security Act of 1974 ("ERISA"), as well as the
terms of any retirement plan in connection with which the Policy has been
purchased. The ERISA rules relating to loans are complex and vary depending on
the individual circumstances of each Policy. Employers and policyowners should
consult with qualified advisers before exercising the loan privileges.
 
 Policy debt equals the total of all outstanding policy loans and accrued
interest on policy loans. If policy debt exceeds cash value, Chubb Colonial
will notify the policyowner and any assignee of record. A payment at least
equal to the amount of excess policy debt above the cash value must be made to
Chubb Colonial within 61 days from the date the notice is mailed, otherwise,
the Policy will lapse and terminate without value. The Policy may, however,
later be reinstated, subject to satisfactory proof of insurability and the
payment of a reinstatement premium. See "THE POLICY--Reinstatement".
 
 So long as the Policy remains in force, policy debt may be repaid in whole or
in part at any time during the Insured's life. If there is any existing policy
debt, premium payments in the amount of the Planned Periodic Premium, received
at the Premium Frequency, will be applied as premium. Premium payments in
excess of the Planned Periodic Premium or premium payments received other than
at the Premium Frequency, will first be applied as policy loan repayments,
then as premium when the policy debt is repaid. For policyowners with both
Type A and Type B loans, repayments of the loan will be applied first to Type
B loans and then to Type A loans. Upon repayment, the Policy's accumulation
value securing the repaid portion of the debt in the General Account will be
transferred to the General Account and the divisions of Separate Account B
using the same percentages used to allocate net premiums. A policyowner may
make loan repayments on a pre-authorized check basis. Any outstanding policy
debt is subtracted from life insurance proceeds payable at the Insured's
death, from accumulation value upon surrender, and from cash value payable at
maturity. In the event that the Policy lapses due to insufficient cash value
resulting from loans, the policyowner may be taxed on the total appreciation
under the Policy. In addition, if the policy is surrendered or allowed to
lapse, the policyholder may be taxed on amounts received as loans that are
cancelled in the transaction. See "FEDERAL TAX MATTERS".
 
                                 OTHER MATTERS
 
 Voting Rights. To the extent required by law, Chubb Colonial will vote the
Funds' shares held in the various divisions of Separate Account B at regular
and special shareholder meetings of the Funds in accordance with instructions
received from persons having voting interests in Separate Account B. If,
however, the 1940 Act or any regulation thereunder should be amended or if the
present interpretation thereof should change and, as a result, Chubb Colonial
determines that it is permissible to vote the Funds' shares in its own right,
it may elect to do so. The number of votes on which each policyowner has the
right to instruct will be determined by dividing the Policy's accumulation
value in a division of Separate Account B by the net asset value per share of
the corresponding Portfolio in which the division invests, or as otherwise
required by law. Fractional shares will be counted. The number of votes on
which the policyowner has the right to instruct will be determined as of the
date coincident with the date established by the Funds for determining
shareholders eligible to vote at the meeting
 
                                      29
<PAGE>
 
of the Funds. Voting instructions will be solicited by written communications
prior to such meeting in accordance with procedures established by the Funds.
Chubb Colonial will vote the Funds' shares as to which no instructions are
received in proportion to the voting instructions which are received with
respect to all Policies participating in the Funds in accordance with
applicable law. Each person having a voting interest will receive proxy
material, reports and other materials relating to the Funds. The shares held
by Chubb Colonial, including shares for which no voting instructions have been
received, shares held in Separate Account B representing charges imposed by
Chubb Colonial against Separate Account B under the Policies and shares held
by Chubb Colonial that are not otherwise attributable to Policies, will also
be voted by Chubb Colonial in proportion to instructions received from the
owners of variable life insurance policies funded through Separate Account B.
Chubb Colonial reserves the right to vote any or all such shares at its
discretion to the extent consistent with then current interpretations of the
1940 Act and rules thereunder.
 
 Chubb Colonial may, when required by state insurance regulatory authorities,
disregard voting instructions if the instructions require that shares be voted
so as to cause a change in subclassification or investment objective of the
Funds or disapprove an investment advisory contract of the Funds. In addition,
Chubb Colonial may disregard voting instructions in favor of changes initiated
by a policyowner in the investment policy or the investment adviser of the
Funds if Chubb Colonial reasonably disapproves of such changes. A change would
be disapproved only if the proposed change is contrary to state law or
prohibited by state regulatory authorities or Chubb Colonial determined that
the change would be inconsistent with the investment objectives of Separate
Account B or would result in the purchase of securities for Separate Account B
which vary from the general quality and nature of investments and investment
techniques utilized by other separate accounts created by Chubb Colonial or
any affiliate of Chubb Colonial which have similar investment objectives. In
the event that Chubb Colonial does disregard voting instructions, a summary of
that action and the reason for such actions will be included in the next semi-
annual report to the policyowner.
 
 Additions, Deletions or Substitutions of Investments. Chubb Colonial reserves
the right, subject to compliance with applicable law, to make additions to,
deletions from, or substitutions for the shares held by any division or which
any division may purchase. If shares of the Funds should no longer be
available for investment or if, in the judgment of Chubb Colonial's
management, further investment in shares of the Funds should become
inappropriate in view of the purposes of the Policy, Chubb Colonial may
substitute shares of any other investment company for shares already
purchased, or to be purchased in the future under the Policies. No
substitution of securities will take place without notice to and consent of
policyowners and without prior approval of the Commission, all to the extent
required by the 1940 Act. Any surrender due to a change in the Portfolio's
investment policy will incur any applicable surrender charges.
 
 Each class of the Funds' stock is subject to certain investment restrictions
which may not be changed without the approval of the majority of the holders
of such series. See the accompanying prospectuses for the Funds.
 
 Any action taken by Chubb Colonial, pursuant to this provision, is subject to
the approval of the New York State Insurance Department.
 
 Annual Summary. Each year a summary will be sent to the policyowner which
shows the current accumulation value, cash value, premiums paid and all
charges since the last annual summary as well as the balance of outstanding
policy loans. Chubb Colonial will also send to the policyowner the reports
required by the 1940 Act.
 
 Confirmation. Confirmation notices (or other appropriate notification) will
be mailed promptly at the time of the following transactions:
 
   (1) policy issue;
 
   (2) receipt of premium payments;
 
   (3) initial allocation among divisions on the allocation date;
 
   (4) transfers among divisions;
 
   (5) change of premium allocation;
 
   (6) change between Option I and Option II;
 
   (7) increases or decreases in Specified Amount;
 
   (8) withdrawals;
 
   (9) receipt of loan repayments; and
 
   (10) reinstatements.

 Limitation on Right to Contest. Chubb Colonial will not contest or revoke the
insurance coverage provided under the Policy, except for any applied for
increase in Specified Amount, after the Policy has been in force during the
lifetime of the Insured for a period of two years from the Issue Date. This
provision does not apply to any benefits provided by a rider which grants
disability benefits or an added benefit in the event that death results from
an accident. Any increase in the Specified Amount will not be contested after
such increase has been in force during the lifetime of the Insured for two
years following the effective date of the increase. Within the two year period
following an increase in Specified Amount, only statements in the application
for such increase will be subject to contestability.
 
 Misstatements. If the age or sex of the Insured has been misstated in an
application, including a reinstatement application, the amount payable under
the Policy by reason of the death of the Insured will be equal to the sum of
the following:
 
   1. The accumulation value on the date of death less any policy debt; and
 
   2. The death benefit, less the accumulation value on the date of death,
  multiplied by the ratio of (a) the cost of insurance actually deducted at
  the beginning of the policy month in which the death occurs to (b) the cost
  of insurance that should have been deducted at the Insured's true age or
  sex.
 
 Suicide. The Policy does not cover the risk of suicide within two years from
the Issue Date or two years from the date of any increase in Specified Amount
with respect to such increase, unless otherwise specified by state law. In the
event of suicide within two years of the Issue Date, the only liability of
Chubb Colonial will be a refund of premiums paid, without interest, less any
policy debt and less any withdrawal. In the event of suicide within two years
of an increase in Specified Amount, the only liability of Chubb Colonial will
be a refund of the cost of insurance for such increase, plus death benefits
payable without regard to suicide, if any.
 
 Beneficiaries. The original beneficiaries and contingent beneficiaries are
designated by the policyowner on the application. If changed, the primary
beneficiary or contingent beneficiary is as shown in the latest change filed
with Chubb Colonial. One or more primary or contingent beneficiaries may be
named in the application. In such case, the proceeds of the Policy will be
paid in equal shares to the survivors in the appropriate beneficiary class
unless requested otherwise by the policyowner.
 
 Postponement of Payments. Payment of any amount upon surrender, withdrawal,
policy loan, or benefits payable at death or maturity may be postponed
whenever: (i) the New York Stock Exchange is closed other than customary week-
end and holiday closings, or trading on the New York Stock Exchange is
restricted as determined by the Commission or (ii) an emergency exists, as
determined by the Commission, as a result of which disposal of securities is
not reasonably practicable or it is not reasonably practicable to determine
the value of net assets in Separate Account B.
 
 Assignment. The Policy can be assigned as collateral security. Chubb Colonial
must be notified in writing if the Policy has been assigned. Each assignment
will be subject to any payments made or action taken by Chubb Colonial prior
to its notification of such assignment. Chubb Colonial is not responsible for
the validity of an assignment. A policyowner's rights and the rights of the
beneficiary may be affected by an assignment. See "Federal Tax Matters."
 
 Illustration of Benefits and Values. After the policy date, the policyowner
may request illustrations of death benefits, accumulation values and cash
values at any time after the policy date. Illustrations will be based on the
existing accumulation value and cash value at the time of the request and both
the maximum and the then current costs of insurance rates. Such illustrations
are currently available to policyowners at no charge. Although Chubb Colonial
reserves the right to assess a charge, no greater than $25 and with advance
notice to policyowners, it has no present intention to do so. See "CHARGES AND
DEDUCTIONS--Administrative Fees."
 
 Non-Participating Policy. The Policy does not share in any surplus
distributions of Chubb Colonial. No dividends are payable with respect to the
Policy.
 
                              THE GENERAL ACCOUNT
 
POLICYOWNERS MAY ALLOCATE NET PREMIUMS AND TRANSFER ACCUMULATION VALUE TO THE
GENERAL ACCOUNT. BECAUSE OF EXEMPTIVE AND EXCLUSIONARY PROVISIONS, INTERESTS
IN THE GENERAL ACCOUNT HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
1933 AND THE GENERAL ACCOUNT HAS NOT BEEN REGISTERED AS AN INVESTMENT COMPANY
UNDER THE 1940 ACT. ACCORDINGLY, NEITHER THE GENERAL ACCOUNT NOR ANY INTERESTS
THEREIN ARE SUBJECT TO THE PROVISIONS OF THESE ACTS, AND
 
                                      31
<PAGE>
 
COLONIAL HAS BEEN ADVISED THAT THE STAFF OF THE SECURITIES AND EXCHANGE
COMMISSION HAS NOT REVIEWED THE DISCLOSURES IN THIS PROSPECTUS RELATING TO THE
GENERAL ACCOUNT. DISCLOSURES REGARDING THE GENERAL ACCOUNT MAY, HOWEVER, BE
SUBJECT TO CERTAIN GENERALLY APPLICABLE PROVISIONS OF THE FEDERAL SECURITIES
LAWS RELATING TO THE ACCURACY AND COMPLETENESS OF STATEMENTS MADE IN
PROSPECTUSES.
 
 General Description. The General Account consists of all assets owned by
Chubb Colonial other than those in Separate Account B and other separate
accounts which may be established by Chubb Colonial. Subject to applicable
law, Chubb Colonial has sole discretion over the investment of the assets of
the General Account.
 
 A policyowner may elect to allocate net premiums to the General Account or to
transfer accumulation value to or from the divisions of Separate Account B and
the General Account. The allocation or transfer of funds to the General
Account does not entitle a policyowner to share in the investment experience
of the General Account. Instead, Chubb Colonial guarantees that accumulation
value in the General Account will accrue interest daily at an effective annual
rate of at least 4 1/2%, independent of the actual investment experience of
the General Account. Chubb Colonial is not obligated to credit interest at any
higher rate, although Chubb Colonial may, in its sole discretion, do so.
 
 If the Date of Receipt of the initial premium is prior to the date Chubb
Colonial either issues the Policy or offers to issue the Policy on a basis
other than as applied for, that initial net premium, less any monthly
deductions, will be credited with interest at the rate currently being
credited to the General Account. This amount will be credited with interest
for the period between the date the premium is received (or the policy date,
whichever is later) and the date Chubb Colonial issues the Policy or the
applicant refuses Chubb Colonial's offer to issue the Policy on a basis other
than as applied for. No interest will be credited for the above period if the
initial premium is less than $500. In those instances when Chubb Colonial
declines to issue a Policy, the entire premium paid will be returned. If the
premium is greater than $500, the premium will be returned with interest.
Interest will be credited from the Date of Receipt to the date the application
is rejected. No interest will be credited for such initial premiums if the
Policy issued as applied for is not accepted or the "free look" is exercised;
Chubb Colonial will retain any interest earned. See "The Policy--Policy "Free
Look" ".
 
 The Policy. This Prospectus describes a flexible premium variable life
insurance policy. Net premiums may be allocated to the General Account or to
Separate Account B or to both. This Prospectus is generally intended to serve
as a disclosure document for the aspects of the Policy involving Separate
Account B. For more information regarding the General Account, see the Policy
itself, or discuss the Policy with your insurance agent.
 
 General Account Benefits. If the policyowner pays the same premiums as
scheduled, allocates all net premiums only to the General Account and makes no
transfers, withdrawals, or policy loans, the minimum amount and duration of
the death benefit will be fixed and guaranteed. The policyowner may select
either death benefit Option I or II under the Policy and may change the
Policy's Specified Amount subject to satisfactory evidence of insurability, if
required.
 
 General Account Accumulation Value. Net premiums allocated to the General
Account are credited to the Policy. Prior to the allocation date, the initial
net premium is deposited in the General Account, and those net premiums are
credited to the Policy. On the allocation date the initial net premium
payments deposited in the General Account, plus interest earned, will be
allocated among the divisions of Separate Account B and the General Account as
instructed by the policyowner in the application. The accumulation value in
the General Account on the allocation date is equal to the portion of the net
premium payments, plus interest earned, which have been paid and allocated to
the General Account, less the portion of the first monthly deduction allocated
to the General Account.
 
 Chubb Colonial guarantees that interest credited to each policyowner's
accumulation value in the General Account will not be less than an effective
annual rate of at least 4 1/2% per year. Chubb Colonial may, IN ITS SOLE
DISCRETION, credit a higher rate of interest, although it is not obligated to
credit interest in excess of 4 1/2% per year, and might not do so. ANY
INTEREST CREDITED ON THE POLICY'S ACCUMULATION VALUE IN THE GENERAL ACCOUNT IN
EXCESS OF THE GUARANTEED RATE OF 4 1/2% PER YEAR WILL BE DETERMINED IN THE
SOLE DISCRETION OF CHUBB COLONIAL. THE POLICYOWNER ASSUMES THE RISK THAT
INTEREST CREDITED MAY NOT EXCEED THE GUARANTEED MINIMUM RATE OF 4 1/2% PER
YEAR. Accumulation value in the General Account that equals indebtedness will
be credited interest daily at annual rate of 6%. The accumulation value in the
General Account will be calculated on each monthly anniversary date of the
Policy, or on any other date with consistent adjustments.
 
 Chubb Colonial guarantees that, at any time prior to the maturity date, the
accumulation value in the General Account will not be less than the amount of
the net premiums allocated or accumulation value transferred to the General
Account, plus interest at the rate of 4 1/2% per year, plus any excess
interest which Chubb Colonial credits and any amounts transferred
 
                                      32
<PAGE>
 
into the General Account, less the sum of all charges allocable to the General
Account and any amounts deducted from the General Account in connection with
withdrawals or transfers to Separate Account B.
 
 Determination of Charges. The portion of the monthly deduction attributable
to the General Account will be determined as of the actual monthly anniversary
date, even if the monthly anniversary date does not fall on a valuation date.
 
 Premium Deposit Fund. As a convenience to policyowners, Chubb Colonial
permits policyowners to deposit funds in a premium deposit fund ("PDF"),
subject to the terms and conditions of the appropriate agreement. Funds
deposited in the PDF earn interest at a minimum annual rate of 4%, with
interest credited on each monthly anniversary date. Interest on these funds is
not tax deferred and will be annually reported on Form 1099 to the
policyowner. An amount equal to the Planned Periodic Premium will be
transferred on the policy date to pay premiums on the policy. Policyowners may
withdraw all or part of the funds from the PDF at any time. No commissions are
earned or paid until premium payments are made pursuant to transfers from the
PDF.
 
                          DISTRIBUTION OF THE POLICY
          
 The Policy will be sold by individuals who, in addition to being licensed as
life insurance agents for Chubb Colonial, are also registered representatives
of broker-dealers who have entered into written sales agreement with the
principal underwriter, Jefferson Pilot Variable Corporation. Any such broker-
dealers will be registered under the Securities Exchange Act of 1934 and their
representatives selling the Policies will be authorized under applicable
insurance laws and regulations to sell insurance products of this type.
Commissions are payable under various schedules and accordingly will vary from
the form of commissions schedule selected. In any event, commissions to
registered representatives are not expected to exceed 90% of first year target
premium and 4% of first year excess premium, and 4% of target premium for both
renewals and excess premium in the second through fifteenth policy years.
Compensation arrangements vary among broker-dealers. Alternative commission
schedules will reflect differences in up-front commissions versus ongoing
asset-based compensation. In addition, override payments, expense allowances
and bonuses based on specific production levels may be paid. No separate
deductions from premiums are made to pay sales commissions or sales expenses.
       
 The Distribution Agreement with Jefferson Pilot Variable Corporation took
effect on January 1, 1998 and continues until terminated by either party on 60
days notice. Jefferson Pilot Variable Corporation is not obligated to sell any
specified amount of Policies and may not assign its responsibilities under the
Distribution Agreement. Chubb Colonial will reimburse Jefferson Pilot Variable
Corporation for its expenses under the Distribution Agreement.     
   
 Jefferson Pilot Variable Corporation is engaged in the sale and distribution
of various other securities, including other flexible premium variable life
policies. It acts as principal underwriter for other flexible premium variable
life policies and variable annuity contracts issued by Chubb Colonial (and its
affiliated companies), and for the Jefferson Pilot Variable Fund, Inc.
(formerly the Chubb America Fund, Inc.).     
 
 The Policies may also be sold through other broker-dealers that enter into
agreements with Chubb Securities Corporation for this purpose. Any such
broker-dealers will be registered under the Securities Exchange Act of 1934
and their representatives selling the Policies will be authorized under
applicable insurance laws and regulations to sell insurance products of this
type. It is not expected that the compensation paid by Chubb Colonial in
connection with such sales will exceed that described above for sales by Chubb
Securities Corporation's registered representatives.

                      STATE REGULATION OF CHUBB COLONIAL
 
 Chubb Colonial Life Insurance Company is governed under the laws of the state
of New Jersey and is subject to regulation by the Insurance Commissioner of
New Jersey. An annual statement is filed with the New Jersey Insurance
Commissioner on or before March 1 of each year covering the operations and
reporting on the financial condition of Chubb Colonial as of December 31 of
the preceding year. Periodically, the Commissioner examines the assets and
liabilities of Chubb Colonial and Separate Account B and verifies their
adequacy and a full examination of Chubb Colonial's operations is conducted by
the Commissioner at least every five years.
 
 In addition, Chubb Colonial is subject to the insurance laws and regulations
of other states within which it is licensed to operate. Generally, the
insurance department of any other state applies the laws of the state of
domicile in determining permissible investments.
 
                              FEDERAL TAX MATTERS
 
 Tax Considerations. The following description is a brief summary of some of
the tax rules, primarily related to federal income taxes under the Code,
which, in the opinion of Chubb Colonial, are currently in effect.
 
 Policy Proceeds. The Policy contains provisions not found in traditional life
insurance policies providing only for fixed benefits. However, under the Code,
the Policy should qualify as a life insurance contract for federal income tax
purposes, with the result that all death benefits paid under the Policy will
generally be fully excludable from the gross income of the Policy's
beneficiary for federal income tax purposes. Policyowners should consult with
their own tax advisers in this regard.
 
                                      35
<PAGE>
 
 The federal income tax treatment of a distribution from the Policy will
depend on whether a Policy is a life insurance policy and also if it is
determined to be a "modified endowment contract," as defined by the Code.
Chubb Colonial will notify a policyowner if the amount of premiums paid in
would cause a Policy to be a modified endowment contract and will allow a
refund of the excess premium. Thus, the policyowner may choose to have the
Policy treated as a modified endowment contract.
 
 A modified endowment contract is a life insurance policy which fails to meet
a "seven-pay" test. In general, a policy will fail the seven-pay test if the
cumulative amount of premiums paid under the policy at any time during the
first seven policy years exceeds a calculated premium level. The calculated
seven-pay premium level is based on a hypothetical policy issued on the same
insured persons and for the same initial death benefit which, under specified
conditions (which include the absence of expense and administrative charges),
would be fully paid for after seven years. Your policy will be treated as a
modified endowment unless the cumulative premiums paid under your policy, at
all times during the first seven policy years, are less than or equal to the
cumulative seven-pay premiums which would have been paid under the
hypothetical policy on or before such times.
 
 Whenever there is a "material change" under a policy, it will generally be
treated as a new contract for purposes of determining whether the policy is a
modified endowment, and subject to a new seven-pay premium period and a new
seven-pay limit. The new seven-pay limit would be determined taking into
account, under a prospective adjustment formula, the Policy Account Value of
the policy at the time of such change. A materially changed policy would be
considered a modified endowment if it failed to satisfy the new seven-pay
limit. A material change could occur as a result of a change in death benefit
option, the selection of additional benefits, the restoration of a terminated
policy and certain other changes.
 
 If the benefits under your policy are reduced, for example, by requesting a
decrease in Face Amount, or in some cases by making partial withdrawals,
terminating additional benefits under a rider, changing the death benefit
option, or as a result of policy termination, the calculated seven-pay premium
level will be redetermined based on the reduced level of benefits and applied
retroactively for purposes of the seven-pay test. If the premiums previously
paid are greater than the recalculated seven-pay premium level limit, the
policy will become a modified endowment. Generally, a life insurance policy
which is received in exchange for a modified endowment or a modified endowment
which terminates and is restored, will also be considered a modified
endowment.
 
 If a policy is deemed to be a modified endowment contract, any distribution
from the policy will be taxed in a manner comparable to distributions from
annuities (i.e., on an "income-first" basis); distributions for this purpose
include a loan, pledge, assignment or partial withdrawal. Any such
distributions will be considered taxable income to the extent accumulated
value under the policy exceeds investment in the policy.
 
 A 10% penalty tax will apply to the taxable portion of such a distribution.
No penalty will apply to distributions (i) to taxpayers 59 1/2 years of age or
older, (ii) in the case of a disability which can be expected to result in
death or to be of indefinite duration or (iii) received as part of a series of
substantially equal periodic payments for the life (or life expectancy) of the
taxpayer or the joint lives (or joint life expectancies) of the taxpayer and
his beneficiary.
 
 To the extent a policy becomes a modified endowment contract, any
distribution, as defined above, which occurs in the policy year it becomes a
modified endowment contract and in any year thereafter will be taxable income
to the policyowner to the extent that accumulation value exceeds investment in
the policy, as described above. Also, any distributions within two years
before a policy becomes a modified endowment contract will also be income
taxable to the policyowner. The Secretary of the Treasury has been authorized
to prescribe rules which would similarly treat other distributions made in
anticipation of a policy becoming a modified endowment contract. For purposes
of determining the amount of any distribution includible in income, all
modified endowment contract policies that fail the above-described tests which
are issued by the same insurer, or its affiliates, to the same policyowner
during any calendar year are treated as one contract. The Secretary of the
Treasury is also authorized to issue regulations in this connection.
 
 In addition to the distribution rules for modified endowment contracts, the
Code and proposed regulations thereunder require that, for policies entered
into on or after October 21, 1988, reasonable mortality and other charges be
used in satisfying the definition of life insurance. The death benefit under a
policy which meets this definition will continue to be excluded from the
beneficiary's gross income. Chubb Colonial believes that the Policies meet
this definition. As long as a
 
                                      36
<PAGE>
 
Policy does not violate the tests prescribed under the Code, it will not fail
to meet the tests of the Code and the general tax provisions described herein
still apply.
 
 The foregoing summary does not purport to be complete or to cover all
situations, and, as always, there is some degree of uncertainty with respect
to the application of the current tax laws. In addition to the provisions
discussed above, the United States Congress may consider other legislation
which, if enacted, could adversely affect the tax treatment of life insurance
policies. Also, the Treasury Department may amend current regulations or adopt
new regulations with respect to this and other Code provisions. Therefore,
policyowners are advised to consult a tax adviser or attorney for more
complete tax information, specifically regarding the applicability of the Code
provisions to an individual policyowner's situation.
 
 Under normal circumstances, if the Policy is not a modified endowment
contract, loans received under the Policy will be construed as indebtedness of
the policyowner. Policyholders are advised to consult a tax adviser or
attorney regarding the deduction of interest paid on loans.
 
 Even if the Policy is not a modified endowment contract, a partial withdrawal
together with a reduction in death benefits during the first 15 policy years
may create taxable income for the policyowner. The amount of that taxable
income is determined under a complex formula and it may be equal to part or
all of, but not greater than, the income on the contract. A partial withdrawal
made after the first 15 policy years will be taxed on a recovery of premium-
first basis, and will only be subject to federal income tax to the extent such
proceeds exceed the total amount of premiums the policyowner has paid that
have not been previously withdrawn.
 
 If a policyowner makes a partial withdrawal, surrender, loan or exchange of
the Policy, Chubb Colonial may be required to withhold federal income tax from
the portion of the money received by the policyowner that is includible in the
policyowner's federal gross income. A policyowner who is not a corporation may
elect not to have such tax withheld; however, such election must be made
before Chubb Colonial makes the payment. In addition, if a policyowner fails
to provide Chubb Colonial with a correct taxpayer identification number
(usually a social security number) or if the Treasury notifies Chubb Colonial
that the taxpayer identification number which has been provided is not
correct, the election not to have such taxes withheld will not be effective.
In any case, a policyowner is liable for payment of the federal income tax on
the taxable portion of money received, whether or not an election to have
federal income tax withheld is made. If a policyowner elects not to have
federal income tax withheld, or if the amount withheld is insufficient, then
the policyowner may be responsible for payment of estimated tax. A policyowner
may also incur penalties under the estimated tax rules if the withholding and
estimated tax payments are insufficient. Chubb Colonial suggests that
policyowners consult with a tax adviser or attorney as to the tax implications
of these matters.
 
 In the event that a Policy is owned by the trustee under a pension or profit
sharing plan, or similar deferred compensation arrangement, the tax
consequences of ownership or receipt of proceeds under the Policy could differ
from those stated herein. However, if ownership of such a Policy is
transferred from the plan to a plan participant (upon termination of
employment, for example), the Policy will be subject to all of the federal tax
rules described above. A Policy owned by a trustee under such a plan may be
subject to restrictions under ERISA and a tax adviser should be consulted
regarding any applicable ERISA requirements.
 
 The Policy may also be used in various arrangements, including nonqualified
deferred compensation or salary continuation plans, split dollar insurance
plans, executive bonus plans and others, where the tax consequences may vary
depending on the particular facts and circumstances of each individual
arrangement. A tax adviser should be consulted regarding the tax attributes of
any particular arrangement where the value of it depends in part on its tax
consequences.
 
 Federal estate and local estate, inheritance and other tax consequences of
ownership or receipt of policy proceeds depend upon the circumstances of each
policyowner and beneficiary.
 
 Current Treasury regulations set standards for diversification of the
investments underlying variable life insurance policies in order for such
policies to be treated as life insurance. Chubb Colonial believes it presently
is in compliance with the diversification requirements as set forth in the
regulations and intends to remain in compliance with such diversification
requirements. If the diversification requirements are not satisfied, the
Policy would not be treated as a life insurance contract. As a consequence to
the policyowner, income earned on a Policy would be taxable to the policyowner
for any calendar quarter in which the diversification requirements were not
satisfied, and for all subsequent calendar quarters.

 The Secretary of the Treasury may issue a regulation or a ruling which will
prescribe the circumstances in which a policyowner's control of the
investments of a segregated asset account may cause the policyowner, rather
than the insurance company, to be treated as the owner of the assets of the
account. The regulation or ruling could impose requirements that are not
reflected in the Policy, relating, for example, to such elements of
policyowner control as premium allocation, transfer privileges and investment
in a division focusing on a particular investment sector. Failure to comply
with any such regulation or ruling presumably would cause earnings on a
policyowner's interest in Separate Account B to be includible in the
policyowner's gross income in the year earned. Chubb Colonial, however, has
reserved certain rights to alter the Policy and investment alternatives so as
to comply with such regulation or ruling. Chubb Colonial believes that any
such regulation or ruling would apply prospectively. Since the regulation or
ruling has not been issued, there can be no assurance as to the content of
such regulation or ruling or even whether application of the regulation or
ruling will be prospective. For these reasons, policyowners are urged to
consult with their own tax advisers.
 
 In 1996 Congress amended the Code to clarify the tax treatment of accelerated
benefits. Effective January 1, 1997, Section 101(g) of the Code now provides
that accelerated death benefits may be excluded from gross income provided
that certain conditions are met. Chubb believes that the Terminal Illness
Accelerated Benefit Rider meets those conditions. In addition, the legislation
clarified the status of such riders under Section 7702 of the Code, including
that the inclusion or conformance of any rider to the law's requirements does
not constitute a material change for purposes of the definition of life
insurance or modified endowment contracts.
 
 Policyowners are also advised that there is some uncertainty as to whether
the Primary Insured Term Rider will be treated as a "Qualified Additional
Benefit" under Section 7702(f)(5)(A)(iii) of the Code rather than as a death
benefit under the Policy. However, Chubb Colonial believes that this rider, as
structured and implemented by Chubb Colonial, would be considered as part of
the death benefit under the Policy and therefore not give rise to any adverse
tax consequences. The policyowner should consult a tax adviser before adding
the Primary Insured Term Rider to the Policy.
 
 The foregoing summary does not purport to be complete or to cover all
situations, including the possible tax consequences of changes in ownership.
Counsel and other competent advisers should be consulted for more complete
information.
   
 Charge for Chubb Colonial Income Taxes. Chubb Colonial is presently taxed as
a life insurance company under the provisions of the Code. The Code
specifically provides for adjustments in reserves for variable policies, and
Chubb Colonial will include flexible premium life insurance operations in its
tax return in accordance with these rules.     
 
 Currently, no charge is made against Separate Account B for Chubb Colonial's
federal income taxes, or provisions for such taxes, that may be attributable
to Separate Account B. Chubb Colonial may charge each division in Separate
Account B for its portion of any income tax charged to Chubb Colonial on the
division or its assets. Under present laws, Chubb Colonial may incur state and
local taxes (in addition to premium taxes) in several states. At present,
these taxes are not significant. If they increase, however, Chubb Colonial may
decide to make charges for such taxes or provisions for such taxes against
Separate Account B. Chubb Colonial would retain any investment earnings on any
tax charges accumulated in a division. Any such charges against Separate
Account B or its divisions could have an adverse effect on the investment
experience of such division.
 
                            EMPLOYEE BENEFIT PLANS
 
 Employers and employee organizations should consider, in consultation with
counsel, the impact of Title VII of the Civil Rights Act of 1964 on the
purchase of a Policy in connection with an employment-related insurance or
benefit plan. The United States Supreme Court held, in a 1983 decision, that,
under Title VII, optional annuity benefits under a deferred compensation plan
could not vary on the basis of sex.
 
                               LEGAL PROCEEDINGS
 
 There are no legal proceedings to which Separate Account B is a party or to
which the assets of any of the divisions thereof are subject. Chubb Colonial
is not involved in any litigation that is of material importance in relation
to its total assets or that relate to Separate Account B.

                                    EXPERTS
 
 The financial statements of Chubb Colonial as of December 31, 1996 and for
the year then ended, appearing in this Prospectus and Registration Statement
have been audited by Ernst & Young LLP, independent auditors, as set forth in
their report thereon appearing elsewhere herein and in the Registration
Statement, and are included in reliance upon such report given upon the
authority of such firm as experts in accounting and auditing.
   
 Actuarial matters included in this Prospectus have been examined by Richard
C. Dielensnyder, FSA, MAAA as stated in the opinion filed as an exhibit to the
registration statement.     
 
                            REGISTRATION STATEMENT
 
 A registration statement has been filed with the Securities and Exchange
Commission under the Securities Act of 1933, as amended, with respect to the
Policy offered hereby. This Prospectus does not contain all the information
set forth in the registration statement and the amendments and exhibits to the
registration statement to all of which reference is made for further
information concerning Separate Account B, Chubb Colonial and the Policy
offered hereby. Statements contained in this Prospectus as to the contents of
the Policy and other legal instruments are summaries. For a complete statement
of the terms thereof reference is made to such instruments as filed.
 
                             FINANCIAL STATEMENTS
 
 The financial statements of Chubb Colonial which are included in this
Prospectus should be considered only as bearing on the ability of Chubb
Colonial to meet its obligations under the Policy. They should not be
considered as bearing on the investment experience of the assets held in
Separate Account B.
 
 In the second quarter of 1996, the Company announced a plan to exit the group
health insurance business. A definitive agreement was reached May 31, 1996
with Healthsource Inc. under which Healthsource acquired the Company's 85%
interest in Chubb Health, Inc. The sale was completed on December 31, 1996.
The Company also discontinued the marketing of traditional group health
indemnity business.
 
 During the fourth quarter of 1996, the Company's parent, The Chubb
Corporation, announced its intention to evaluate its strategic alternatives
with respect to the life insurance companies, including the possible sale or
spin-off of the business. The Chubb Corporation entered into a definitive
agreement dated February 23, 1997 to sell Chubb Life Insurance Company of
America and its subsidiaries, which include Chubb Colonial Life Insurance
Company, to Jefferson-Pilot Corporation for $875,000,000. The sale was
effective on April 30, 1997.
 
 No financial statements of Separate Account B are included in this Prospectus
because, as of December 31, 1996, the end of Separate Account B's most recent
fiscal year, Separate Account B had no assets or liabilities and had not yet
commenced operations.

                               DECEMBER 31, 1996
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
BASIS OF PRESENTATION
 
  The accompanying financial statements have been prepared in accordance with
generally accepted accounting principles (GAAP). Chubb Colonial Life Insurance
Company (the Company), formerly The Colonial Life Insurance Company of
America, is wholly-owned by Chubb Life Insurance Company of America (Chubb
Life). Chubb Life is a wholly-owned subsidiary of The Chubb Corporation (the
Parent). On February 23, 1997, The Chubb Corporation entered into a definitive
agreement to sell Chubb Life and its subsidiaries, including the Company, to
Jefferson-Pilot Corporation. (see Note 13).
 
  The Company is principally engaged in the sale of individual life insurance
and investment products. These products are marketed primarily through
personal producing general agents throughout the United States.
 
  In the second quarter of 1996, the Company adopted a plan to exit the group
insurance business. Accordingly, the group insurance business has been
classified as discontinued operations in the financial statements. (see Note
2).
 
  Affiliates of the Company include Chubb Sovereign Life Insurance Company
(Sovereign) and Chubb America Service Corporation (Chubb Service).
 
  The financial statements reflect estimates and judgments made by management
which affect the reported amounts of assets and liabilities at the date of the
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.
 
RECOGNITION OF REVENUES, BENEFITS, CLAIMS AND EXPENSES:
 
UNIVERSAL LIFE PRODUCTS
 
  Universal life products include universal life insurance and other interest-
sensitive life insurance policies. Revenues for universal life products
consist of policy charges for the cost of insurance, policy administration and
surrenders that have been assessed against policy account balances during the
period.
 
  Policy fund liabilities for universal life and other interest-sensitive life
insurance policies are computed in accordance with the retrospective deposit
method and represent policy account balances before surrender charges.
 
  Policy claims that are charged to expense include claims incurred in the
period in excess of related policy account balances. Other policy benefits
include interest credited to universal life and other interest-sensitive life
insurance policies. Interest crediting rates ranged from 4% to 6 1/2%.
 
INVESTMENT PRODUCTS
 
  Investment products include structured settlement annuities and other
supplementary contracts without life contingencies. Revenues for investment
products consist of policy charges for the cost of insurance, policy
administration and surrenders that have been assessed against policy account
balances during the period. Deposits for these products are recorded as policy
fund liabilities, which are increased by interest credited to the liabilities
and decreased by withdrawals and administrative charges assessed against the
contract holders. Interest crediting rates ranged from 3 1/2% to 6 3/4%.
 
TRADITIONAL LIFE INSURANCE PRODUCTS
 
  Traditional life insurance products include those products with fixed and
guaranteed premiums and benefits. Premium revenues for traditional life
insurance are recognized as revenues when due. The liabilities for future
policy benefits are computed by the net level premium method based on
estimated future investment yield, mortality and withdrawal experience.
Interest rate assumptions ranged from 3% to 9%. Mortality is calculated
principally on an experience multiple applied to select and ultimate tables in
common usage in the industry. Estimated withdrawals are determined principally
based on industry tables. Policy benefits and claims are charged to expense as
incurred.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
 
ACCIDENT AND HEALTH INSURANCE
 
  Accident and health insurance premiums are earned on a monthly pro rata
basis over the terms of the policies. Benefits include paid claims plus an
estimate for known claims and claims incurred but not reported as of the
balance sheet date.
 
REINSURANCE
 
  In the ordinary course of business, the Company assumes and cedes
reinsurance with other insurance companies. These arrangements minimize the
maximum net loss potential arising from large risks. Ceded reinsurance
contracts do not relieve the Company from its obligation to policyholders. The
Company evaluates the financial condition of its reinsurers and monitors
concentrations of credit risk arising from similar activities or economic
characteristics of the reinsurers to minimize its exposure to significant
losses from reinsurer insolvencies.
 
  Reinsurance recoverable on life and health policy liabilities represent
estimates of the portion of such liabilities that will be recovered from
reinsurers, determined in a manner consistent with the liabilities associated
with the reinsured policies.
 
DEFERRED POLICY ACQUISITION COSTS
 
  Certain costs of acquiring insurance contracts, principally commissions,
underwriting costs and certain variable field office expenses are deferred.
Deferred policy acquisition costs for universal life and investment contracts
are amortized over the lives of the contracts in relation to the present value
of estimated gross profits expected to be realized. Deferred policy
acquisition costs related to universal life and investment contracts are also
adjusted to reflect the effect that the unrealized gains or losses on
investments classified as available-for-sale would have had on the present
value of estimated gross profits had such gains or losses actually been
realized. This adjustment is excluded from income and charged or credited
directly to the unrealized appreciation or depreciation of the investments
component of shareholder's equity, net of applicable deferred income tax.
 
  Traditional life insurance deferred policy acquisition costs are being
amortized over the premium-payment period of the related policies using
assumptions consistent with those used in computing policy benefit reserves.
 
INVESTED ASSETS
 
  Short term investments, which have an original maturity of one year or less,
are carried at amortized cost.
 
  Fixed maturities, which include bonds and redeemable preferred stocks, are
purchased to support the investment strategies of the Company. These
strategies are developed based on many factors, including rate of return,
maturity, credit risk, tax considerations and regulatory requirements. Those
fixed maturities which the Company has the ability and intent to hold to
maturity are considered held-to-maturity and carried at amortized cost. Fixed
maturities which may be sold prior to maturity to support the investment
strategies of the Company are considered available-for-sale and carried at
market value as of the balance sheet date.
 
  Equity securities, which include common stocks and non-redeemable preferred
stocks, are carried at market value as of the balance sheet date.
 
  Policy loans are carried at the unpaid balances. Mortgage loans on real
estate are carried at the unpaid balances, adjusted for amortization of
premium or discount.
 
  Realized gains and losses on the sale of investments are determined on the
basis of the cost of the specific investments sold and are credited or charged
to income. Unrealized appreciation or depreciation of investments classified
as available-for-sale, net of the deferred policy acquisition costs adjustment
discussed above and the applicable deferred income tax, is excluded from
income and credited or charged directly to a separate component of
shareholder's equity.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
 
PROPERTY AND EQUIPMENT
 
  Property and equipment used in operations are carried at cost less
accumulated depreciation. Depreciation is calculated using the straight-line
method over the estimated useful lives of the assets.
 
FEDERAL INCOME TAXES
 
  The Company participates in the filing of a consolidated federal income tax
return with Chubb Life. Chubb Life joins in the filing of a consolidated
federal income tax return with its parent. Federal income tax is allocated as
if the Company and Chubb Life filed separate income tax returns.
 
  Deferred income tax assets and liabilities are recognized for the expected
future tax effects attributable to temporary differences between the financial
reporting and tax bases of assets and liabilities, based on enacted tax rates
and other provisions of tax law. Deferred income taxes related to unrealized
appreciation or depreciation of investments classified as available-for-sale
are charged or credited directly to a separate component of shareholder's
equity.
 
FAIR VALUES OF FINANCIAL INSTRUMENTS
 
  Fair values of financial instruments are based on quoted market prices where
available. Fair values of financial instruments for which quoted market prices
are not available are based on estimates using present value or other
valuation techniques. Those techniques are significantly affected by the
assumptions used, including the discount rates and the estimates of future
cash flows. Accordingly, the derived fair value estimates cannot be
substantiated by comparison to independent markets and are not necessarily
indicative of the amounts that could be realized in immediate settlement of
the instrument. Certain financial instruments, particularly insurance
contracts, are excluded from fair value disclosure requirements.
 
  The methods and assumptions used to estimate the fair value of certain
financial instruments are as follows:
 
  .  Fair values of fixed maturities with active markets are based on quoted
     market prices. For fixed maturities that trade in less active markets,
     fair values are obtained from independent pricing services. Fair values
     of fixed maturities are principally a function of current interest
     rates. Care should be used in evaluating the significance of these
     estimated market values.
 
  .  Fair values of equity securities are based on quoted market prices.
 
  .  The carrying value of short term investments approximates fair value due
     to the short maturities of these investments.
 
  .  Fair values of policy loans and mortgage loans are estimated using
     discounted cash flow analyses and approximate carrying values.
 
  .  The carrying value of short term debt approximates fair value due to the
     short maturities of the debt.
 
  The carrying value and fair value of financial instruments at December 31,
   1996, are as follows:

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
 
CASH FLOW INFORMATION
 
  In the statement of cash flows, short term investments are not considered to
be cash equivalents. Cash overdrafts included in accrued expenses and other
liabilities were $5,217,000 at December 31, 1996.
 
2. DISCONTINUED OPERATIONS
 
  In the second quarter of 1996, the Company adopted a plan to exit the group
insurance business. Formerly, this business was the Company's group insurance
business segment.
 
  Marketing of traditional group business was discontinued. Due to various
contractual and regulatory requirements, traditional group coverages will be
renewed in certain jurisdictions until an orderly transition to another
carrier or termination of the coverage can occur. It is expected that the exit
from this business will be completed by the end of 1998.
 
  The identifiable assets and liabilities of the group insurance business as
of December 31, 1996 included in the accompanying balance sheet, by the
respective category, were as follows:

  In addition to the assets and liabilities above, sufficient invested assets
were held for the payment of group insurance liabilities. It is not
practicable to determine the specific invested assets associated with those
liabilities.

6. FEDERAL INCOME TAXES
 
  The federal income tax provision for the year ended December 31, 1996 has
been computed using the tax rates and regulations in effect during the year.
The provision for federal income tax gives effect to permanent differences
between financial and taxable income. Accordingly, the effective tax rate is
lower than the statutory federal corporate tax rate. The reasons for the lower
effective tax rate were as follows:

                               DECEMBER 31, 1996
 
6. FEDERAL INCOME TAXES (CONTINUED)
 
  Prior to 1984, life insurance companies were allowed certain special
deductions for federal income tax purposes which could become subject to tax
at normal rates under certain circumstances, including distribution to
shareholders. These special deductions were set aside in a Policyholders'
Surplus Account. Under the 1984 Act, no further additions to this account are
permitted. At December 31, 1996, approximately $4,664,000 of untaxed retained
earnings remained. No income taxes have been provided since management does
not anticipate any transaction that would cause this remaining amount to
become taxable. The unrecognized deferred tax related to the Policyholders'
Surplus Account is $1,632,000.
 
  Federal income taxes paid in 1996 were $5,728,000.
 
7. RELATED-PARTY TRANSACTIONS
 
SERVICE AGREEMENT
 
  The Company entered into an agreement with Chubb Service, whereby Chubb
Service agrees to furnish to the Company, Chubb Life and other affiliated

were $42,983,000. Amounts payable to Chubb Service, included in other
liabilities, at December 31, 1996 were $8,059,000.
 
  The Company participates in the defined benefit noncontributory pension plan
of The Chubb Corporation which covers substantially all employees. Pension
costs allocated to the Company for the year ended December 31, 1996 were
$637,000. The costs were offset by a curtailment gain of $1,322,000 resulting
from workforce reductions.
 
  The Company, with Chubb Life and its affiliates, provides certain other
postretirement benefits, principally health care and life insurance, to
retired employees and their beneficiaries and covered dependents.
Substantially all employees may become eligible for these benefits upon
retirement if they meet minimum age and years of service requirements.
Postretirement benefit costs allocated to the Company for the year ended
December 31, 1996 were $578,000. The costs were offset by a curtailment gain
of $648,000 resulting from workforce reductions.

was $196,000.

first mortgage obtained by Chubb Life on December 9, 1985. The first mortgage
loan is secured by a home office building, located at One Granite Place,
Concord, NH. The outstanding balance of the loan at December 31, 1996 was
$4,369,000.
 
8. JOINT MARKETING AGREEMENT
 
  The Company entered into an agreement with a health maintenance organization
(HMO) to jointly create, market and service managed care point-of-service
products in the State of New York. Net reimbursements paid to the HMO during
1996 were $351,000. At December 31, 1996 the net receivable from the HMO was

  The Company is involved in both the cession and assumption of reinsurance
with other insurance companies. Risks are reinsured with other companies to
permit the recovery of a portion of the direct losses. The Company's
reinsurance activity is primarily with Chubb Life. The maximum amount of
individual life insurance retained on any one life, including accidental death
benefits, is $1,400,000.
 
  Selected data regarding reinsurance amounts appearing in the financial
statements for 1996 were as follows:

10. DIVIDEND RESTRICTIONS
 
  The Company is required to file annual statements with state insurance
regulatory authorities prepared on an accounting basis prescribed or permitted
by such authorities (statutory basis). GAAP differs in certain respects from
statutory accounting practices.
 
  A comparison of shareholder's equity on a GAAP basis and policyholders'
surplus on a statutory basis as of December 31, 1996 is as follows:

  The Company may pay dividends from statutory earned surplus as determined in
accordance with accounting practices prescribed or permitted by regulatory
authorities and the State of New Jersey. Dividend distributions exceeding the
greater of 10% of policyholders' surplus or statutory net income during the
preceding year are considered "extraordinary" and are subject to the prior
approval of the State of New Jersey Department of Insurance. The maximum
ordinary dividend distribution that may be made by the Company to Chubb Life
during 1997 is approximately $13,000,000.
 
11. DEBT AND CREDIT ARRANGEMENTS
 
  The Company borrowed in the short term commercial paper market during 1996.
These notes were issued by Chubb Capital Corporation, a subsidiary of The
Chubb Corporation. The interest rate was variable and was based on Chubb
Capital Corporation's cost of funds. Interest paid on the borrowings in 1996
was $1,206,000. The outstanding balance was repaid in the fourth quarter of
1996. At December 31, 1996, the agreement remains in effect with no
outstanding borrowings.

12. LITIGATION
 
  The Company is involved in pending or threatened lawsuits arising from the
normal conduct of its insurance business. Several suits have been brought
against the Company seeking both punitive and compensatory damages. Management
is of the opinion that these suits are substantially without merit, that valid
defenses exist, and that such litigation will not have a material effect on
the financial statements.
 
13. SUBSEQUENT EVENT RELATING TO CHANGE IN OWNERSHIP
 
  The Chubb Corporation entered into a definitive agreement, dated February
23, 1997, to sell Chubb Life and its subsidiaries, including the Company, to
Jefferson-Pilot Corporation for $875,000,000 in cash, subject to various
closing adjustments and other customary conditions. The sale is subject to
regulatory approvals and is expected to be completed by the end of the second
quarter of 1997.

                                  APPENDIX A
 
                     ILLUSTRATIONS OF ACCUMULATION VALUES
                        CASH VALUES AND DEATH BENEFITS
 
  Following are a series of tables that illustrate how the accumulation
values, cash values and death benefits of a policy change with the investment
performance of the Portfolios. The tables show how the accumulation values,
cash values and death benefits of a Policy issued to an insured of a given age
and given premium would vary over time if the return on the assets held in
each Portfolio were a constant gross, after tax annual rate of 0%, 4%, and
12%. The tables on pages A-2 through A-7 illustrate a Policy issued to a male,
age 40, under a standard rate non-smoker underwriting risk classification. The
accumulation values, cash values and death benefits would be different from
those shown if the returns averaged 0%, 4%, and 12% over a period of years,
but fluctuated above and below those averages for individual policy years.
 
  The amount of the accumulation value exceeds the cash value during the first
ten policy years due to the surrender charge. For policy years eleven and
after, the accumulation value and cash value are equal, since the surrender
charge has been reduced to zero.
 
  The second column shows the accumulation value of the premiums paid at the
stated interest rate. The third and sixth columns illustrate the accumulation
values and the fourth and seventh columns illustrate the cash values of the
Policy over the designated period. The accumulation values shown in the third
column and the cash values shown in the fourth column assume the monthly
charge for cost of insurance is based upon the current cost of insurance rates
as discounted. The current cost of insurance rates are based on the sex, issue
age, policy year, rating class of the Insured, and the Specified Amount of the
Policy. The accumulation values shown in the sixth column and the cash values
shown in the seventh column assume the monthly charge for cost of insurance is
based upon the maximum cost of insurance rates allowable, which are based on
the Commissioner's 1980 Standard Ordinary Mortality Table. The current cost of
insurance rates are different for Specified Amounts below $100,000 and above
$249,999; therefore, the values shown would change for Specified Amounts below
$100,000 and above $249,999. The fifth and eighth columns illustrate the death
benefit of a Policy over the designated period. The illustrations of death
benefits reflect the same assumptions as the accumulation values and cash
values. The death benefit values also vary between tables, depending upon
whether Option I or Option II death benefits are illustrated.
   
  The amounts shown for the death benefit, accumulation values, and cash
values reflect the fact that the net investment return of the divisions of
Separate Account B is lower than the gross return on the assets in the
Portfolios, as a result of expenses paid by the Portfolios and charges levied
against the divisions of Separate Account B.     
   
  The policy values shown take into account a daily investment advisory fee
equivalent to the maximum annual rate of .66% of the aggregate average daily
net assets of the Portfolios plus a charge of .17% of the aggregate average
daily net assets to cover estimated expenses to be incurred by the Emerging
Growth Portfolio and actual expenses incurred by the remaining nine Portfolios
for the twelve months ended December 31, 1995. The .66% investment advisory
fee is the average of the individual investment advisory fees of the thirteen
Portfolios. The .17% expense figure is based on a weighted average utilizing
actual average net assets for the Chubb America Fund Portfolio and the
Templeton International Fund and estimated average net assets for the VIP and
VIP II Portfolio A anticipated for the period ending December 31, 1996.
Expenses for the Templeton International Fund, High Income Portfolio, Index
500 Portfolio and Contrafund Portfolio, were provided by the investment
manager for these portfolios and Chubb Colonial has not independently verified
such information. The policy values also take into account a daily charge to
each division of Separate Account B for assuming mortality and expense risks
which is equivalent to a charge at an annual rate of .90% of the average net
assets of the divisions of Separate Account B for policy year one through ten,
and .65% of the average net assets of the divisions of Separate Account B for
policy years eleven and thereafter. After deduction of these amounts, the
illustrated gross investment rates of 0%, 4%, and 12% correspond to
approximate net annual rates of -1.72%, 2.28% and 10.28%, respectively.     
   
  The hypothetical values shown in the tables do not reflect any charges for
federal income taxes or other taxes against Separate Account B since Chubb
Colonial is not currently making such charges. However, if, in the future,
such charges are made, the gross annual investment rate of return would have
to exceed the stated investment rates by a sufficient amount to cover the tax
charges in order to produce the accumulation values, cash values and death
benefits illustrated.     
 
  The tables illustrate the policy values that would result based on
hypothetical investment rates of return if premiums are paid in full at the
beginning of each year, if all net premiums are allocated to Separate Account
B, and if no policy loans have been made. The values would vary from those
shown if the assumed annual premium payments were paid in installments during
a year. The values would also vary if the policyowner varied the amount or
frequency of premium payments. The tables also assume that the policyowner has
not requested an increase or decrease in Specified Amount, that no withdrawals
have been made and no surrender charges imposed, and that no transfers have
been made and no transfer charges imposed.
 
  Upon request, Chubb Colonial will provide, without charge, a comparable
illustration based upon the proposed insured's age, sex and rating class, the
face amount requested, the proposed frequency and amount of premium payments
and any available riders requested. Existing policyowners may request
illustrations based on existing cash value at the time of request. Chubb
Colonial has reserved the right to charge an administrative fee up to $25 for
such illustrations.

                         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

                     UNDERTAKING REGARDING INDEMNIFICATION

     Insofar as indemnification for liability arising under the Securities Act 
of 1933 may be permitted to directors, officers and controlling persons of the 
registrant, the registrant has been advised that in 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 
registrant of expense incurred or paid by a director, officer or controlling 
person of the registrant in the successful defense of any action, suit or 
proceeding) is asserted by such director, officer of controlling person in 
connection with the securities being registered, the registrant 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

Chubb Colonial Life Insurance Company
One Granite Place
Concord, New Hampshire 03301

Gentlemen:

This opinion is furnished in connection with the filing of post-effective 
Amendment No. 5 to the registration statement of Chubb Colonial Life Insurance 
Company ("Colonial") on Form S-6, ("Registration Statement") of interests in 
Chubb Separate Account B under its variable life insurance policies 
(collectively, the "Policies"). This opinion covers the flexible premium 
variable life insurance policy ("Colonial Ensemble II").

I am familiar with the terms of the Policies, and the Registration Statement and
the Exhibits thereto. In my opinion:

1.   The illustrations of death benefits, accumulation value, and cash value for
     the Policies in Appendix A of the prospectus, based on the assumptions
     stated in the illustrations, are consistent with the provisions of the
     Policies.

     The Policies have not been designed so as to make the relationship between
     premiums and benefits, as shown in the illustrations, appear
     disproportionately more favorably to prospective purchasers of Policies for
     the age(s), gender(s), smoking status(es), and underwriting class(es)
     illustrated in Appendix A than to prospective purchasers of Policies for
     other age(s), gender(s), smoking status(es), and underwriting class(es).
     The particular illustrations shown were not selected for the purpose of
     making this relationship appear more favorable. Generally, the rates for
     non-smokers are lower than for smokers and the rates for females are lower
     than for males.

2.   The illustrations of death benefits, accumulation value and cash value for
     the Policies, set forth in Appendix A of the prospectus, based on the net
     return of the five divisions of Chubb Separate Account B and the
     assumptions stated within the example, are consistent with the provisions
     of the Policies.

     The illustrations in Appendix A have not been designed so as to make the
     relationship between premiums and benefits appear disproportionately more
     favorable to prospective purchasers of Policies for age(s), gender(s),
     smoking status(es), and underwriting class(es) illustrated in Appendix A
     than to prospective purchasers of Policies for other age(s), gender(s),
     smoking status(es), and underwriting class(es). Generally, the rates for
     non-smokers are lower than for smokers and the rates for females are lower
     than for males.

3.   The illustrations set forth in Appendix A of the prospectus contain both
     the current and guaranteed rates of cost of insurance charges to be used
     for those Policies.

     These rates have not been designed so as to make the relationship between
     current and guaranteed rates appear disproportionately more favorable to
