                                  DEFINITIONS
    
 
ACCUMULATION UNIT: An accounting unit of measure used to calculate Sub- Account
Value prior to the Annuity Calculation Date.
 
   
ADMINISTRATIVE OFFICE OF HARTFORD: Currently located at 200 Hopmeadow Street,
Simsbury, CT. All correspondence concerning this Contract should be sent to P.O.
Box 5085, Hartford, CT 06102-5085, Attn.: Individual Annuity Services, except
for overnight or express mail packages, which should be sent to: 200 Hopmeadow
Street, Simsbury, CT 06089.
    
 
ANNIVERSARY VALUE: The Commuted Value calculated as of a Contract Anniversary.
 
ANNUITANT: The person (or persons) whose life (or lives) determines the Annuity
Payments payable under the Contract and whose death determines the Death Benefit
after the Income Start Date. With regard to joint and last survivor Annuity
Payment Options, the maximum number of joint Annuitants is two and provisions
referring to the death of an Annuitant mean the death of the last surviving
Annuitant. Provisions relating to an action by the Annuitant mean, in case of
joint Annuitants, both Annuitants acting jointly. Unless otherwise specified,
the Contract Owner is the Annuitant.
 
ANNUITY CALCULATION DATE: The date as of which the first Annuity Payment will be
calculated. It will be no more than five days prior to the Income Start Date.
Values calculated prior to the Income Start Date but after the Annuity
Calculation Date will equal values as of the Annuity Calculation Date.
 
ANNUITY PAYMENT: One of several periodic payments made by Hartford to the Payee
under an Annuity Payment Option.
 
ANNUITY PAYMENT OPTION: The form of Annuity Payments selected by the Contract
Owner. The Annuity Payment Option is shown on the Contract specifications page

ANNUITY UNIT: An accounting unit of measure used to calculate the amount of

ANNUITY UNIT FACTOR: The factor applied in computing Annuity Unit values to
neutralize the effect of the Assumed Investment Return.
 
   
ASSUMED INVESTMENT RETURN (AIR): The annual rate of return shown on the
specification page of the Contract. This rate is used to determine the degree of
fluctuation in the amount of Variable Annuity Payments in response to
fluctuations in the net investment return of selected Sub-Accounts by assuming
(among other things) that the assets in the Sub-Accounts supporting the Contract
will have a net annual return over the anticipated Annuity Payment period equal
to that rate of return. If the actual performance of the selected Sub-Accounts
is equal to the AIR, the Annuity Payment will be constant. If the actual
performance is greater than the AIR, the Annuity Payment will increase. If the
actual performance is less than the AIR, the Variable Annuity Payment amount
will be lower.
    
 
BENEFICIARY: The person(s) entitled to receive the Contract Value upon the death
of the Contract Owner or Annuitant prior to the Income Start Date or, the Death
Benefit upon the death of the Annuitant after the Income Start Date available

of the Contract during which the Contract Owner may return the Contract.
 
CODE: The Internal Revenue Code of 1986, as amended.
 
COMMISSION: U.S. Securities and Exchange Commission.
 
   
COMMUTED VALUE: The present value of the remaining guaranteed Annuity Payments
under an Annuity Payment Option having Annuity Payments guaranteed for a
specified number of years, computed using the Assumed Investment Return for the
Contract and the Annuity Unit value(s) calculated as of the date that Hartford
receives a fully completed request for surrender, or Due Proof of Death of the
Annuitant.
    
 
CONTRACT ANNIVERSARY: The same date in each Contract Year as the Contract Issue
Date.
 
CONTRACT ISSUE DATE: The date on which Hartford issues the Contract and on which
the Contract becomes effective. The Contract Issue Date is shown on the
specifications page of the Contract and is used to determine Contract Years and
Contract Anniversaries.
 
CONTRACT OWNER(S): The person (or persons) who owns (or own) the Contract and
who is (are) entitled to exercise all rights and privileges provided in the
Contract. The maximum number of joint Contract Owners is two. Provisions
relating to action by the Contract Owner mean, in the case of joint Contract
Owners, both Contract Owners acting jointly.
 
CONTRACT VALUE: The sum of the Sub-Account Values under the Contract prior to
the Annuity Calculation Date.
 
CONTRACT YEAR: A 12-month period beginning on the Contract Issue Date or on a
Contract Anniversary.
 
DEATH BENEFIT: The amount payable by Hartford based upon the death of the
Contract Owner or Annuitant prior to the Income Start Date, or upon the death of
Annuitant on or after the Income Start Date. The Death Benefit is calculated as
of the date that Due Proof of Death is received at Hartford.

                                    SUMMARY
    
 
                              GENERAL DESCRIPTION
 
   
    This Prospectus is designed to provide prospective Contract Owners with
information necessary to decide whether or not to purchase a Contract. This
summary provides a concise description of the more significant aspects of the
Contract. Further detail is provided in this Prospectus, the related Statement
of Additional Information, the Contract, and the prospectus for the Funds. For
further information, contact the Administrative Office of Hartford or your
registered representative.
    
 
                             PURCHASING A CONTRACT
 
   
    A prospective Contract Owner may purchase a Contract by completing and
submitting an application or an order request along with a single Premium
Payment to the Administrative Office of Hartford. The minimum Premium Payment
for a Contract is $25,000 and the maximum Premium Payment generally is
$1,000,000 (See "Purchasing a Contract," page 11), unless approved by Hartford.
    
 
   
    Subject to certain minimum allocation requirements that may be in effect
from time to time, the Premium Payment is allocated to each Sub-Account as
specified on the application or order request. All percentage allocations must
be in whole numbers. (See "Crediting and Allocating Premium Payment," page 12.)
    
 
                         RIGHT TO EXAMINE THE CONTRACT
 
   
    Contract Owners may cancel the Contract during the Cancellation Period and
receive a refund equal to the Contract Value. The Cancellation Period is a
ten-day period of time beginning when the Contract is received by a Contract
Owner. Some states require a longer Cancellation Period and return of the
Premium Payment. (See "Right to Examine the Contract," page 11.)
    
 
                                   TRANSFERS
 
   
    Prior to the Annuity Calculation Date, a Contract Owner may transfer all or
part of any Sub-Account Value to another available Sub-Account(s), subject to
certain restrictions. (See "Sub-Account Value Transfers," page 13.) Similar
transfers may be made after the Income Start Date, subject to certain
restrictions. (See "Variable Annuity Payments," page 16.)
    
 
                            ANNUITY PAYMENT OPTIONS
 
    The following Annuity Payment Options are available under the Contract: LIFE
ANNUITY; LIFE ANNUITY WITH CASH REFUND; LIFE ANNUITY WITH PAYMENTS GUARANTEED
FOR A SPECIFIED NUMBER OF YEARS; JOINT AND LAST SURVIVOR; JOINT AND LAST
SURVIVOR LIFE ANNUITY WITH PAYMENTS GUARANTEED FOR A SPECIFIED NUMBER OF YEARS;
and PAYMENTS GUARANTEED FOR A SPECIFIED NUMBER OF YEARS.
 
                                 DEATH BENEFITS
 
   
    The Contract provides for a Death Benefit, under certain Annuity Payment
Options, in the event the Annuitant or Contract Owner(s) die(s) prior to the
Income Start Date and if the Annuitant dies after the Income Start Date. (See
"Payment Upon the Death of Any Contract Owner or the Annuitant," page  - .)
Certain Annuity Payment Options do not provide a Death Benefit.
    
 
                                   SURRENDERS
 
   
    Upon Written Notice prior to the Annuity Calculation Date, a Contract Owner
may surrender the Contract and receive the Contract Value. On or after the
Income Start Date under a PAYMENTS GUARANTEED FOR A SPECIFIED NUMBER OF YEARS
Annuity Payment Option, a Contract Owner also may surrender the Contract for the
Surrender Value. (See "Surrenders," page 13.) Surrenders may have adverse
federal income tax consequences including the possibility of being subject to a
penalty tax. (See "Federal Tax Considerations," page 20.)
    
 
                                CHARGES AND FEES
 
    The following charges and fees are assessed under the Contracts:
 
    CONTINGENT DEFERRED SALES CHARGE. Hartford deducts a contingent deferred
sales charge if the Contract is surrendered after the Income Start Date under
PAYMENTS GUARANTEED FOR A SPECIFIED NUMBER OF YEARS ANNUITY PAYMENT OPTION. The
contingent deferred sales charge is 6% of the Commuted Value (less any
applicable Premium Tax charge) if surrendered during the first two Contract
Years; 5% of the Commuted Value (less any applicable Premium Tax charge) if
surrendered during the third or fourth contract years; and decreases 1% each
Contract Year up to and including the seventh Contract Year. The contingent
deferred sales charge is 0% if the Contract is surrendered after the seventh
Contract Year. No contingent deferred sales charge is assessed upon the death of
the Annuitant after the Income Start Date.
 
   
    MORTALITY AND EXPENSE RISK CHARGE. Hartford makes a daily charge of
0.003446% (approximately equivalent to an effective annual rate of 1.25%) of the
Separate Account's net assets to compensate it for assuming certain mortality
and expense risks. (See "Mortality and Expense Risk Charge," page 18.)

- --------------------------------------------------------------------------------
 
   
    PREMIUM TAX CHARGE. Generally, taxes, if any, on the Premium Payment are
incurred as of the Annuity Calculation Date, and a Premium Tax Charge is
deducted from the Contract Value as of that date. These taxes currently range
from 0% to 4.0% of the Premium Payment. (See "Premium Tax Charge," page 18.)
    
 
    EXPENSES OF THE FUNDS. The investment experience of each Sub-Account
reflects that of the Fund whose shares it holds. The investment experience of
each Fund, in turn, reflects its fees and other operating expenses. Please read

                                SEPARATE ACCOUNT
 
    The Separate Account is a separate investment account of Hartford
established under Connecticut law on May 20, 1991. Hartford owns the assets of
the Separate Account. These assets are held separate from Hartford's general
account and its other separate accounts. That portion of the Separate Account's
assets that is equal to the reserves and other Contract liabilities of the
Separate Account is not chargeable with liabilities arising out of any other
business Hartford may conduct.
 
    The Separate Account is registered with the Commission under the Investment
Company Act of 1940 (the "1940 Act") as a unit investment trust and meets the
definition of a "separate account" under the federal securities laws. Such
registration does not involve any supervision by the Commission of the
management of the Separate Account or of Hartford. The Separate Account is also
governed by the laws of Connecticut, Hartford's state of domicile, and may also
be governed by laws of other states in which Hartford does business.
 
   
    The investment in the Separate Account is allocated to one or more Sub-
Accounts as per the Contract Owner's specifications. Each Sub-Account is
invested exclusively in the assets of one underlying Fund. The Separate Account
has 12 Sub-Accounts, each of which invests in shares of a corresponding Fund.
Income, gains and losses, realized or unrealized, from assets allocated to a
Sub-Account are credited to or charged against that Sub-Account without regard
to other income, gains or losses of Hartford.
    
 
   
    CHANGES TO THE SEPARATE ACCOUNT. Hartford may make the following changes to
the Separate Account:
    
 
1.  Any changes required by the 1940 Act or other applicable law or regulation;
 
2.  combine separate accounts, including the Separate Account;
 
3.  add new Sub-Accounts to or remove existing Sub-Accounts from the Separate
    Account or combine Sub-Accounts;
 
4.  make Sub-Accounts (including new Sub-Accounts) available to such classes of
    Contracts as Hartford may determine;
 
5.  add new Funds or remove existing Funds;
 
6.  substitute new Funds for any existing Fund if shares of the Fund are no
    longer available for investment or if Hartford determines that investment in
    a Fund is no longer appropriate in light of the purposes of the Separate
    Account;
 
7.  de-register the Separate Account under the 1940 Act if such registration is
    no longer required; and
 
8.  operate the Separate Account as a management investment company under the
    1940 Act or as any other form permitted by law.
 
    No such changes will be made without any necessary approval of the
Commission and applicable state insurance departments. Contract Owners will be
notified of any changes.
 
                                   THE FUNDS
 
   
    Each Sub-Account invests in a corresponding Fund. Each of the Funds is an
open-end diversified management

    No one can assure that any Fund will achieve its stated objectives and
policies. Since each underlying Fund has different investment objectives, each
is subject to different risks. More detailed information concerning the
investment objectives, policies and restrictions of the Funds, the expenses of
the Funds, the risks attendant to investing in the Funds and other aspects of
their operations can be found in the current prospectus for each Fund which
accompanies this Prospectus and the current statement of additional information
for the Funds. THE FUNDS' PROSPECTUS AND STATEMENT OF ADDITIONAL INFORMATION CAN
BE ALSO OBTAINED BY CALLING 1-800-862-6668. The Funds' prospectus should be read
carefully before any decision is made concerning the allocation of the Premium
Payment or transfers of Contract Value among the Sub-Accounts.
    
 
   
    Hartford cannot guarantee that each Fund will always be available under the
Contracts, but in the unlikely event that a Fund is not available, Hartford will
take reasonable steps to secure the availability of a comparable fund. Shares of
each Fund are purchased and redeemed at Net Asset Value, without a sales charge.
    
 
   
    Shares of the Funds are sold to separate accounts of Hartford and its
insurance company affiliates other than the Separate Account to serve as the
underlying investment for both variable annuity contracts and variable life
insurance contracts, a practice known as "mixed funding." As a result, there is
a possibility that a material conflict may arise between the interests of
Contract Owners, and of owners of other contracts whose contract values are
allocated to one or more of these other separate accounts investing in any one
of the Funds. In the event of any such material conflicts,

Hartford will consider what action may be appropriate, including removing the
Fund from the Separate Account or replacing the Fund with another Fund. There
are certain risks associated with mixed funding,as disclosed in the Funds'
prospectus.
 
   
    ALL FUNDS MAY NOT BE AVAILABLE IN ALL STATES.
    
 
   
                        PERFORMANCE RELATED INFORMATION
    
 
    The Separate Account may advertise certain performance related information
concerning its Sub-Accounts. Performance information about a Sub-Account is
based on the Sub-Account's past performance only and is no indication of future
performance.
 
   
    The Advisers Fund, Bond Fund, Capital Appreciation Fund, Dividend and Growth
Fund, Index Fund, International Advisers Fund, International Opportunities Fund,
MidCap Fund, Mortgage Securities Fund, Small Company Fund, Stock Fund, and Money
Market Fund Sub-Accounts may include total return in advertisements or other
sales material.
    
 
    When a Sub-Account advertises its standardized total return, it will usually
be calculated for one year, five years, and ten years or some other relevant
periods if the Sub-Account has not been in existence for at least ten years.
Total return is measured by comparing the value of an investment in the
Sub-Account at the beginning of the relevant period to the value of the
investment at the end of the period (assuming the deduction of any contingent
deferred sales charge which would be payable if the investment were redeemed at
the end of the period).
 
   
    In addition to the standardized total return, the Sub-Account may advertise
a non-standardized total return. This figure will usually be calculated for one
year, five years, and ten years or other periods. Non-standardized total return
is measured in the same manner as the standardized total return described above,
except that the contingent deferred sales charge is not deducted. Therefore,
non-standardized total return for a Sub-Account is higher than standardized
total return for a Sub-Account.
    
 
   
    The Bond Fund and Mortgage Securities Fund Sub-Accounts may advertise yield
in addition to total return. The yield will be computed in the following manner:
The net investment income per unit earned during a recent one month period,
divided by the unit value on the last day of the period. This figure reflects
the recurring charges at the Separate Account level.
    
 
   
    The Money Market Fund Sub-Account may advertise yield and effective yield.
The yield of the Money Market Sub-Account is based upon the income earned by the
Sub-Account over a seven-day period and then annualized, i.e. the income earned
in the period is assumed to be earned every seven days over a 52-week period and
stated as a percentage of the investment. Effective yield is calculated
similarly but when annualized, the income earned by the investment is assumed to
be reinvested in Sub-Account units and thus compounded in the course of a
52-week period. Yield and effective yield reflect the recurring charges at the
Separate Account level.
    
 
    The Separate Account may also disclose yield, standard total return, and
non-standard total return for periods prior to the date the Separate Account
commenced operations. For periods prior to the date the Separate Account
commenced operations, performance information for the Sub-Accounts will be
calculated based on the performance of the underlying Funds and the assumption
that the Sub-Accounts were in existence for the same periods as those of the
underlying Funds, with a level of charges equal to those currently assessed
against the Sub-Accounts.
 
    Hartford may provide information on various topics to Contract Owners and
prospective Contract Owners in advertising, sales literature or other materials.
These topics may include the relationship between sectors of the economy and the
economy as a whole and its effect on various securities markets, investment
strategies and techniques (such as value investing, dollar cost averaging and
asset allocation), the advantages and disadvantages of investing in tax-
advantaged and taxable instruments, customer profiles and hypothetical purchase
scenarios, financial management and tax and retirement planning, and other
investment alternatives, including comparisons between the Contracts and the
characteristics of and market for such alternatives.
 
   
                          DESCRIPTION OF THE CONTRACTS
    
 
                             PURCHASING A CONTRACT
 
   
    A prospective Contract Owner may purchase a Contract by completing and
submitting an application or an order request. The maximum age for Annuitants on
the Contract Issue Date is 90. A single Premium Payment must be delivered to the
Administrative Office of Hartford along with the Contract Owner's application or
an order request. The minimum Premium Payment is $25,000 unless Hartford
specifically consents to a lower Premium Payment. No additional Premium Payments
may be made under the Contracts. Unless Hartford gives its prior approval, it
will not accept a Premium Payment in excess of $1,000,000. Hartford will send
Contract Owners a confirmation notice upon receipt and acceptance of the
Contract Owner's Premium Payment.
    
 
                         RIGHT TO EXAMINE THE CONTRACT
 
   
    Contract Owners may cancel the Contract during the Cancellation Period,
which is the 10-day period beginning
    
<PAGE>
12                                   HARTFORD LIFE AND ANNUITY INSURANCE COMPANY
- --------------------------------------------------------------------------------
 
   
on the day the Contract Owner receives the Contract. Some states may require a
longer Cancellation Period. To cancel the Contract, the Contract Owner must mail
or deliver within 10 days, a written request for cancellation accompanied by the
Contract to the Administrative Office of Hartford.
    
 
   
    Hartford will refund the Contract Value as of the date of receipt of the
request for cancellation. The Contract Owner bears the investment risk during
the period prior to Hartford's receipt of the request for cancellation. Hartford
will refund the Premium Payment where required by law.
    
 
   
                            CREDITING AND ALLOCATING
                              THE PREMIUM PAYMENT
    
 
    If the application or an order request for a Contract is properly completed
and is accompanied by any additional information necessary to process it, the
Premium Payment will be allocated, as designated by the Contract Owner, to one
or more of the Sub-Accounts within two business days of receipt. If the
application, order request, or other required information is incomplete when
received, Hartford reserves the right to retain the Premium Payment for up to
five business days while it attempts to complete the information. If the
information cannot be made complete within five business days, the applicant
will be informed of the reasons for the delay and the Premium Payment will be
returned unless the applicant specifically consents to Hartford retaining the
Premium Payment until the information is made complete. The Premium Payment will
then be allocated within two business days after receipt of the complete
information.
 
    Contract Owners may allocate the Premium Payment among any or all available
Sub-Accounts subject to minimum amounts then in effect. Currently, amounts
allocated to any one Sub-Account must equal at least 1% of the net Premium
Payment. All percentage allocations must be in whole numbers.
 
   
                    CONTRACT VALUE BEFORE INCOME START DATE
    
 
   
    SUB-ACCOUNT VALUE. The Contract Value is the sum of all Sub-Account Values
and therefore reflects the investment performance of the Sub-Accounts to which
it is allocated. The Sub-Account Value for any Sub-Account as of the Contract
Issue Date is equal to the amount of the Premium Payment allocated to that
Sub-Account. The Sub-Account Value for a Contract is determined on any given day
by the multiplying the number of Accumulation Units attributable to the Contract
in that Sub-Account by the Accumulation Unit value for that Sub-Account.
Therefore, on any Valuation Day the Contract Owner's Sub-Account Value reflects
any variation of the interest income, dividends, net capital gains or losses,
realized or unrealized, and any amounts transferred into or out of that
Sub-Account.
    
 
   
    ACCUMULATION UNITS. The portions of the Premium Payment allocated to a
Sub-Account or amounts of Contract Value transferred to a Sub-Account are
converted into Accumulation Units. For any Contract, the number of Accumulation
Units credited to a Sub-Account is determined by dividing the dollar amount
directed to the Sub-Account by the Accumulation Unit value for that Sub-Account
for the Valuation Day as of which the portion of the Premium Payment or
transferred Contract Value is invested in the Sub- Account. Transferred Contract
Value is invested in a Sub-Account as of the end of the Valuation Period during
which the transfer request was received. Therefore, a Premium Payment or portion
thereof allocated to or amounts transferred to a Sub-Account under a Contract
increase the number of Accumulation Units of that Sub-Account credited to the
Contract.
    
 
    Surrenders, transfers out of a Sub-Account, the death of any Contract Owner
or the Annuitant before the Income Start Date, and the application of Contract
Value less Premium Tax to an Annuity Payment Option on the Annuity Calculation
Date all result in a decrease in the number of Accumulation Units of one or more
Sub-Accounts. Accumulation Units are valued as of the end of the Valuation
Period.
 
    The Accumulation Unit value for each Sub-Account was arbitrarily set
initially at $1 when the Sub-Account began operations. Thereafter, the
Accumulation Unit value at the end of every Valuation Day equals the
Accumulation Unit value at the end of the preceding Valuation Day multiplied by
the Net Investment Factor (described below).
 
   
                           THE NET INVESTMENT FACTOR
                      (BEFORE AND AFTER INCOME START DATE)
    
 
    The Net Investment Factor is an index applied to measure the investment
performance of a Sub-Account from one Valuation Period to the next. For each
Sub-Account, the Net Investment Factor reflects the investment performance of
the Fund in which that Sub-Account invests and the charges assessed against that
Sub-Account for a Valuation Period. The Net Investment Factor is calculated by
dividing (1) by (2) and subtracting (3) from the result, where:
 
(1) is the result of:
 
   
    a.  the Net Asset Value of the Fund held in the Sub-Account, determined at
        the end of the current Valuation Period; plus
    
 
    b.  the per share amount of any dividend or capital gain distributions made
        by the Fund held in the Sub-Account.
<PAGE>
HARTFORD LIFE AND ANNUITY INSURANCE COMPANY                                   13
- --------------------------------------------------------------------------------
 
   
(2) is the Net Asset Value of the Fund held in the Sub-Account, determined at
    the beginning of the Valuation Period.
    
 
(3) is a daily factor representing the mortality and expense risk charge
    deducted from the Sub-Account, adjusted for the number of days in the
    Valuation Period.
 
   
                          SUB-ACCOUNT VALUE TRANSFERS
                       BEFORE AND AFTER INCOME START DATE
    
 
    The Contract Owner may transfer the values of the Sub-Accounts allocations
from one or more Sub-Accounts to another free of charges. However, Hartford
reserves the right to limit the number of transfers to twelve (12) per Contract
Year, with no two (2) transfers occurring on consecutive Valuation Days.
Transfers by telephone may be made by a Contract Owner or by the
attorney-in-fact pursuant to a power of attorney by calling 1-800-862-6668 or by
the agent of record by calling 1-800-862-7155. Telephone transfers may not be
permitted by some states for their residents who purchase variable annuities.
 
    The policy of Hartford and its agents and affiliates is that they will not
be responsible for losses resulting from acting upon telephone requests
reasonably believed to be genuine. Hartford will employ reasonable procedures to
confirm that instructions communicated by telephone are genuine; otherwise,
Hartford may be liable for any losses due to unauthorized or fraudulent
instructions. The procedures Hartford follows for transactions initiated by
telephone include requirements that the callers provide certain information for
identification purposes. All transfer instructions by telephone are tape
recorded.
 
   
    Transfers between Sub-Accounts may be made both before and after the Income
Start Date, provided that the minimum allocation to any Sub-Account may not be
less than $500. All percentage (%) allocations must be in whole numbers (e.g.,
1%).
    
 
   
    It is the responsibility of the Contract Owner to verify the accuracy of all
confirmations of transfers and to promptly advise Hartford of any inaccuracies
within 30 days of receipt of the confirmation. Hartford will send the Contract
Owner a confirmation of the transfer within five days from the date of any
instructions.
    
 
    Subject to exceptions set forth in the following paragraph, the right to
reallocate Contract Values is subject to modification if Hartford determines, in
its sole opinion, that the exercise of that right by one or more Contract Owners
is, or would be, to the disadvantage of other Contract Owners. Any modification
could be applied to transfers to or from some or all of the Sub-Accounts and
could include, but would not be limited to, the requirements of a minimum time
period between each transfer, not accepting transfer requests of an agent acting
under power of attorney on behalf of more than one Contract Owner, or limiting
the dollar amount that may be transferred between the Sub-Accounts by a Contract
Owner at any one time. Such restrictions may be applied in any manner reasonably
designed to prevent any use of the transfer right which is considered by
Hartford to be to the disadvantage of other Contract Owners. Some states may
have certain limitations.
 
    Currently, and with respect to Contracts issued in all states, the only
restriction in effect is that Hartford will not accept instructions from agents
acting under a power of attorney of multiple Contract Owners whose accounts
aggregate more than $2 million, unless the agent has entered into a third party
transfer services agreement with Hartford.
 
                                   SURRENDERS
 
   
    ON OR BEFORE THE INCOME START DATE. Contract for its Surrender Value at any
time on or before the Income Start Date. A Contract's Surrender Value fluctuates
daily as a function of the investment performance of the Sub-Accounts in which a
Contract Owner is invested. Hartford does not guarantee any minimum Surrender
Value. The Surrender Value will be determined as of the date Hartford receives
the Written Notice for surrender at the Administrative Office of Hartford.
    
 
   
    AFTER THE INCOME START DATE. Contract on or after the Income Start Date only
if the PAYMENTS GUARANTEED FOR A SPECIFIED NUMBER OF YEARS Annuity Payment
Option is in effect. Upon such a surrender Hartford pays the Contract Owner the
Commuted Value less any applicable contingent deferred sales charges. This
surrender charge is computed as of the date Hartford receives the Written Notice
for surrender at the Administrative Office of Hartford.
    
 
   
    Contract Owners should consult their tax adviser regarding the tax
consequences of a surrender. A surrender made before age 59 1/2 may result in
adverse tax consequences, including the imposition of a penalty tax of 10% of
the taxable portion of the Surrender Value. See "Federal Tax Considerations,"
page 20 for more details.
    
 
                         DEATH BEFORE INCOME START DATE
 
    If the Contract Owner or the Annuitant dies before the Income Start Date,
Hartford will pay the Death Benefit.
 
    The Death Benefit is an amount equal to the Contract Value. The Contract
Value may be taken in one sum or under any of the settlement options then being
offered by Hartford.
 
    IF THE CONTRACT OWNER DIES before the Income Start Date, any surviving joint
Contract Owner becomes the Beneficiary. If there is no surviving joint Contract
Owner, the designated Beneficiary will be the Beneficiary. If the
<PAGE>
14                                   HARTFORD LIFE AND ANNUITY INSURANCE COMPANY
- --------------------------------------------------------------------------------
 
Contract Owner's spouse is the sole Beneficiary and the Annuitant is living, the
spouse may elect, in lieu of receiving the Contract Value, to be treated as the
Contract Owner. If no Beneficiary designation is in effect or if the Beneficiary
has predeceased the Contract Owner, the Contract Owner's estate will be the
Beneficiary.
 
    IF THE ANNUITANT DIES prior to the Income Start Date and the Contract Owner
is living, the Contract Owner shall be the Beneficiary. In that case, the rights
of any designated Beneficiary shall be voided.
 
                    DEATH ON OR AFTER THE INCOME START DATE
 
    If the Annuitant dies on or after the Income Start Date, Hartford will pay
the Death Benefit under the Annuity Payment Option in effect as of the
Annuitant's death. Under some Annuity Payment Options, there is no Death
Benefit.
 
    The Death Benefit on or after the Income Start Date, under the PAYMENTS
GUARANTEED FOR A SPECIFIED NUMBER OF YEARS ANNUITY PAYMENT OPTION, is the
greatest of:
 
a)  the Commuted Value;
 
b)  100% of the Premium Payment reduced by the aggregate dollar amount of all
    Annuity Payments made since the Income Start Date; and
 
c)  the Maximum Anniversary Value (the greatest Anniversary Value under the
    Contract while the Annuitant is alive prior to his or her 81st birthday
    reduced by the dollar amount of Annuity Payments made since that
    anniversary).
 
    IF THE ANNUITANT DIES on or after the Income Start Date, the Beneficiary
will have the option of having payments continue to the Beneficiary for the
remainder of the period or taking the Death Benefit in one sum.
 
    IF A CONTRACT OWNER WHO IS NOT THE ANNUITANT, DIES on or after the Income
Start Date, any surviving joint Contract Owner becomes the sole Contract Owner.
If there is no surviving Contract Owner, the Payee becomes the new Contract
Owner. If any Contract Owner dies, the remaining Annuity Payments will be
distributed at least as rapidly as under the method of distribution being used
as of the date of such death.
 
                       DETERMINATION OF THE DEATH BENEFIT
 
    The Death Benefit will be calculated as of the date Hartford receives
Written Notice of Due Proof of Death. Any Annuity Payments made on or after the
date of death, but before receipt of Written Notice of Due Proof of Death will
be recovered by Hartford from the Payee.
 
   
    PRIOR TO THE INCOME START DATE, in the absence of complete instructions to
either pay the Death Benefit in one sum or under one of the settlement options
being offered, the Contract Value will be moved to the Hartford Money Market
Fund.
    
 
   
    ON OR AFTER THE INCOME START DATE, in the absence of complete instructions
to either pay the Death Benefit in one sum or continue payments, the present
value of the guaranteed remaining payments will be moved to the Hartford Money
Market Fund.
    
 
   
    Upon receipt of complete instructions, Hartford will proceed as follows: If
the instructions are to resume payments, Hartford will make any payments that
went unpaid since the date Hartford received Written Notice of Due Proof of
Death. Hartford will then reallocate the remaining balance in the Hartford Money
Market Fund according to the instructions and resume payments. If the

                           DISTRIBUTION REQUIREMENTS:
                         PRIOR TO THE INCOME START DATE
    
 
    The Contract Value will be distributed based on the Contract Owner's or
Annuitant's date of death and the Beneficiary's election:
 
1)  in a single lump sum within five years;
 
2)  under an Annuity Payment Option provided that:
 
   
    a)  Annuity Payments begin within one year of the date of death, and
    
 
    b)  Annuity Payments are made in substantially equal installments over the
        life of the Beneficiary, or
 
    c)  Annuity Payments are made in substantially equal installments over a
        period not greater than the life expectancy of the Beneficiary;
 
3)  if the sole Beneficiary is the spouse of the deceased Contract Owner, he or
    she may by Written Notice within one year of the Contract Owner's death,
    elect to continue the Contract as the new Contract Owner. If the spouse so
    elects, all of his or her rights as Beneficiary cease and if the deceased
    Contract Owner was also the sole Annuitant and appointed no contingent
    Annuitant, he or she will become the Annuitant; or
 
4)  if the Contract Owner is not an individual, then the "primary Annuitant"
    shall be treated as the Contract Owner under 1) and 2) above. For this
    purpose, the "primary Annuitant" means the individual, the events in the
    life of whom are of primary importance in affecting the timing or amount of
    the payout under the Contract.

                          PAYMENTS UNDER THE CONTRACT
 
    Hartford generally makes payments of surrenders, Death Benefits, or any
Annuity Payments within seven days of receipt of all applicable Written Notices
and/or Due Proofs of Death. However, Hartford may postpone such payments for any
of the following reasons:
 
1.  when the New York Stock Exchange ("NYSE") is closed for trading other than
    customary holiday or weekend closing, or trading on the NYSE is restricted,
    as determined by the Commission; or
 
2.  when the Commission by order permits a postponement for the protection of
    Contract Owners; or
 
3.  when the Commission determines that an emergency exists that would make the
    disposal of securities held in the Separate Account or the determination of
    their value not reasonably practicable.
 
    If a recent check or draft has been submitted, Hartford has the right to
defer payment of surrenders, payments upon the death of the Contract Owner or
Annuitant before the Income Start Date, Death Benefits, or Annuity Payments
until the check or draft has been honored.
 
   
                              SELECTING AN ANNUITY
                                 PAYMENT OPTION
    
 
   
    The Annuity Payment Option specifies the type of annuity to be paid and
determines how long the annuity will be paid, the frequency of Annuity Payments,
and the amount of each Annuity Payment. The Contract Owner must select the
Annuity Payment Option when applying for the Contract. This election is
irrevocable once the Contract is issued. The Contract Owner must select the
Sub-Accounts to which Contract Value less applicable Premium Tax will be
applied. Unless otherwise directed, Sub-Account values, as they exist on the
Annuity Calculation Date, are used to calculate the first Annuity Payment.
    
 
   
                            ANNUITY PAYMENT OPTIONS
    
 
    LIFE ANNUITY. Hartford makes Annuity Payments to the Payee for as long as
the Annuitant lives. UNDER THIS OPTION, A PAYEE WOULD RECEIVE ONLY ONE ANNUITY
PAYMENT IF THE ANNUITANT DIES AFTER THE FIRST ANNUITY PAYMENT, TWO ANNUITY
PAYMENTS IF THE ANNUITANT DIES AFTER THE SECOND ANNUITY PAYMENT, ETC.
 
   
    LIFE ANNUITY WITH CASH REFUND. Hartford makes Annuity Payments to the Payee
as long as the Annuitant lives. If the Annuitant dies and the sum of all Annuity
Payments made are less than the Contract Value less Premium Tax used to purchase
Annuity Units on the Annuity Calculation Date, the Beneficiary is entitled to a
Death Benefit. The Death Benefit equals the Contract Value less Premium Tax used
to purchase Annuity Units on the Annuity Calculation Date minus the sum of all
Annuity Payments made. This Option is only available using the 5% A.I.R.
    
 
   
    LIFE ANNUITY WITH PAYMENTS GUARANTEED FOR A SPECIFIED NUMBER OF
YEARS. Hartford makes Annuity Payments to the Payee for as long as the Annuitant
lives. At the time this Option is selected, the Contract Owner must select a
specific number of years (a minimum of five years and maximum of: a) 100 minus
the Annuitant's age or b) 40 years, whichever is less). If the Annuitant dies
before the specified number of years has passed, the Beneficiary will have the
option of either having the payments continue to the Beneficiary for the
remainder of the period or receiving the Commuted Value in one sum. Some
restrictions apply to Qualified Contracts with regards to the specified number
of years for which payments are guaranteed.
    
 
    JOINT AND LAST SURVIVOR LIFE ANNUITY. Hartford makes Annuity Payments to the
Payee while both Annuitants are living. After the death of either Annuitant,
Annuity Payments continue to the Payee for as long as the other Annuitant lives.
UNDER THIS OPTION, A PAYEE WOULD RECEIVE ONLY ONE ANNUITY PAYMENT IF BOTH
ANNUITANTS DIE AFTER THE FIRST ANNUITY PAYMENT, ETC. At the time of purchase the
Contract Owner must elect to have Annuity Payments after the death of the first
Annuitant made in amounts equal to 100%, 66.67% or 50% of the amount that would
otherwise be paid.
 
    JOINT AND LAST SURVIVOR LIFE ANNUITY WITH PAYMENTS GUARANTEED FOR A
SPECIFIED NUMBER OF YEARS. Hartford makes Annuity Payments to the Payee while
both Annuitants are living. After the death of either Annuitant, Annuity
Payments continue to the Payee for as long as the other Annuitant lives. At the
time of purchase, the Contract Owner must elect to have Annuity Payments after
the death of the first Annuitant made in amounts equal to 100%, 66.67% or 50% of
the amount that would otherwise be paid. At the time this Option is selected,
the Contract Owner must select a specific number of years (a minimum of five
years and maximum of 100 minus the younger Annuitant's age). If the Annuitants
die before the specified number of years has passed, the Beneficiary will have
the option of either having the payments continue to the Beneficiary for the
remainder of the period or receiving the Commuted Value in one sum. Some
restrictions apply to Qualified Contracts with regards to the specified number
of years for which payments are guaranteed.
 
    PAYMENTS GUARANTEED FOR A SPECIFIED NUMBER OF YEARS. Hartford makes Annuity
Payments to the Payee for the number of years (a minimum of five years and
maximum of 100 minus the Annuitant's age) selected by the Contract Owner. If the
Annuitant dies before the specified number of years has passed, payments to the
Beneficiary will continue until the specified number of years has elapsed. After

death of the Annuitant, the Beneficiary will have the option of either having
the payments continue to the Beneficiary for the remainder of the period or
receiving the Commuted Value in one sum. Some restrictions apply to Qualified
Contracts with regards to the specified number of years for which payments are
guaranteed.
 
    Prior to the death of the Annuitant, the Contract Owner may elect to receive
the Commuted Value. If the Contract Owner makes this election, Hartford will
deduct the contingent deferred sales charge from the Commuted Value before
paying it to the Contract Owner.
 
   
                          ANNUITY CALCULATION DATE AND
                               INCOME START DATE
    
 
    The Contract Owner selects the Income Start Date in the application or order
request. The Annuity Calculation Date will be no more than five Valuation Days
before the Income Start Date. The Contract Value less any applicable Premium Tax
is applied to purchase Annuity Units of the Sub- Accounts selected by the
Contract Owner as of the Annuity Calculation Date. The first Annuity Payment is
computed using the value of such Annuity Units as of the Annuity Calculation
Date.
 
                              INCOME PAYMENT DATES
 
   
    All Annuity Payments after the first Annuity Payment are computed and
payable as of the Income Payment Dates. These dates are the same day of the
month as the Income Start Date based on the Annuity Payment frequency selected
by the Contract Owner and shown on the specification page of the Contract.
Available Annuity Payment frequency includes monthly, quarterly, semi-annual and
annual. The Annuity Payment frequency may not be changed once selected by the
Contract Owner.
    
 
   
    In the event that the Contract Owner does not select an Annuity Payment
frequency, Annuity Payments will be made monthly.
    
 
                           VARIABLE ANNUITY PAYMENTS
 
    THE FIRST VARIABLE ANNUITY PAYMENT. Variable Annuity Payments are periodic
payments from Hartford to the designated Payee, the amount of which varies from
one Income Payment Date to the next as a function of the net investment
performance of the Sub-Accounts selected by the Contract Owner to support such
Annuity Payments. The dollar amount of the first Variable Annuity Payment
depends on the Annuity Payment Option chosen, the age of the Annuitant, the
gender of the Annuitant (if applicable), the amount of Contract Value applied to
purchase the Annuity Payments, and the applicable annuity purchase rates based
on the 1983a Individual Annuity Mortality table using projection scale G
projected to the year 2000 and an Assumed Investment Return of not less than
3.0%.
 
    The dollar amount of the first Variable Annuity Payment attributable to each
Sub-Account is determined by dividing the dollar amount of the Contract Value
less applicable Premium Tax applied to that Sub-Account on the Annuity
Calculation Date by $1,000 and multiplying the result by the Payment Factor in
the Contract for the selected Annuity Payment Option. The dollar value of the
first Variable Annuity Payment is the sum of the first Variable Annuity Payments
attributable to each Sub-Account.
 
   
    ANNUITY UNITS. The number of Annuity Units attributable to a Sub-Account is
derived by dividing the first Variable Annuity Payment attributable to that
Sub-Account by the Annuity Unit value for that Sub-Account for the Valuation
Period ending on the Annuity Calculation Date or during which the Annuity
Calculation Date falls if the Valuation Period does not end on such date. The
number of Annuity Units attributable to each Sub-Account under a Contract
remains fixed unless there is a transfer of Annuity Units between Sub-Accounts.
    
 
   
    SUBSEQUENT VARIABLE ANNUITY PAYMENTS. The dollar amount of each subsequent
Variable Annuity Payment attributable to each Sub-Account is determined by
multiplying the number of Annuity Units of that Sub-Account credited under the
Contract by the Annuity Unit value (described below) for that Sub- Account for
the Valuation Period ending on the Income Payment Date, or during which the
Annuity Payment Date falls if the Valuation Period does not end on such date.
The dollar value of each subsequent Variable Annuity Payment is the sum of the
subsequent Variable Annuity Payments attributable to each Sub-Account.
Notwithstanding the foregoing, when an Income Payment Date would fall on a day
that is not a Valuation Day, the Income Payment is computed as of the Valuation
Day immediately following what would have been the Income Payment Date.
    
 
   
    The Annuity Unit value of each Sub-Account for any Valuation Period is equal
to (a) multiplied by (b) divided by (c) where:
    
 
   
(a) is the Net Investment Factor for the Valuation Period for which the Annuity
    Unit value is being calculated;
    
 
   
(b) is the Annuity Unit value for the preceding Valuation Period; and
    
 
(c) is a daily Assumed Investment Return factor (for the 3%, 5% or 6% Assumed
    Investment Return) adjusted for the number of days in the Valuation Period.
 
    The Annuity Unit Factor is equal to one plus the applicable Assumed
Investment Return percentage. Therefore, for 3%, it is 1.03, for 5% it is 1.05
and for 6% it is 1.06. The annual factors can be translated into daily factor of
1.00008098, 1.00013368, and 1.00015965, respectively.
<PAGE>
HARTFORD LIFE AND ANNUITY INSURANCE COMPANY                                   17
- --------------------------------------------------------------------------------
 
    THE ASSUMED INVESTMENT RETURN. The Annuity Unit value will increase or
decrease from one Income Payment Date to the next in direct proportion to the
net investment return of the Sub-Account or Sub-Accounts supporting the Variable
Annuity Payments, less an adjustment to neutralize the selected Assumed
Investment Return. Dividing what would otherwise be the Annuity Unit value by
the Assumed Investment Return factor is necessary in order to adjust the change
in the Annuity Unit value (resulting from the Net Investment Factor) so that the
Annuity Unit value only changes to the extent that the Net Investment Factor
represents a rate of return greater than or less than the Assumed Investment
Return selected by the Contract Owner. Without this adjustment, the Net
Investment Factor would decrease the Annuity Unit value to the extent that such
value represented an annualized rate of return of less than 0.0% and increase
the Annuity Unit value to the extent that such value represented an annualized
rate of return of greater than 0.0%.
 
   
    Subject to state approval, the Contract permits Contract Owners to select
one of three Assumed Investment Returns: 3%, 5% or 6%. A higher Assumed
Investment Return will result in a higher initial payment, a more slowly rising
series of subsequent payments when actual investment performance (minus any
deductions and expenses) exceeds the Assumed Investment Return, and a more rapid
drop in subsequent payments when actual investment performance (minus any
deductions and expenses) is less than the Assumed Investment Return. The
following examples may help clarify the impact of selecting one Assumed
Investment Return over another:
    
 
   
1.  If a Contract Owner selects a 3% ASSUMED INVESTMENT RETURN and if the net
    investment return of the Sub-Account for an Annuity Payment period is equal
    to the pro-rated portion of the 3% Assumed Investment Return, the Variable
    Annuity Payment attributable to that Sub-Account for that period will equal
    the Annuity Payment for the prior period. To the extent that such net
    investment return exceeds an annualized rate of return of 3% for a payment
    period, the Annuity Payment for that period will be greater than the Annuity
    Payment for the prior period. To the extent that such return for a period
    falls short of an annualized rate of 3%, the Annuity Payment for that period
    will be less than the Annuity Payment for the prior period.
    
 
   
2.  If a Contract Owner selects a 5% ASSUMED INVESTMENT RETURN and if the net
    investment return of the Sub-Account for an Annuity Payment period is equal
    to the pro-rated portion of the 5% Assumed Investment Return, the Variable
    Annuity Payment attributable to that Sub-Account for that period will equal
    the Annuity Payment for the prior period. To the extent that such net
    investment return exceeds an annualized rate of return of 5% for a payment
    period, the Annuity Payment for that period will be greater than the Annuity
    Payment for the prior period. To the extent that such return for a period
    falls short of an annualized rate of 5%, the Annuity Payment for that period
    will be less than the Annuity Payment for the prior period.
    
 
   
3.  If a Contract Owner selects a 6% ASSUMED INVESTMENT RETURN and if the net
    investment return of the Sub-Account for an Annuity Payment period is equal
    to the pro-rated portion of the 6% Assumed Investment Return, the Variable
    Annuity Payment attributable to that Sub-Account for that period will equal
    the Annuity Payment for the prior period. To the extent that such net
    investment return exceeds an annualized rate of return of 6% for a payment
    period, the Annuity Payment for that period will be greater than the Annuity
    Payment for the prior period. To the extent that such return for a period
    falls short of an annualized rate of 6%, the Annuity Payment for that period
    will be less than the Annuity Payment for the prior period.
    
 
   
    Exchange ("Transfer") of Annuity Units. After the Annuity Calculation Date,
the Contract Owner may exchange (i.e., "transfer") the dollar value of a
designated number of Annuity Units of a particular Sub-Account for an equivalent
dollar amount of Annuity Units of another Sub-Account. On the date of the
transfer, the dollar amount of a Variable Annuity Payment generated from the
Annuity Units of either Sub-Account would be the same. Transfers are executed as
of the day Hartford receives Written Notice requesting transfer. For guidelines
refer to "Sub-Account Value Transfers" on page 13.
    
 
   
                           CONTRACT FEES AND CHARGES
    
 
                        CONTINGENT DEFERRED SALES CHARGE
 
   
    No sales charge is deducted from the Premium Payment at the time that the
Premium Payment is made. However, a contingent deferred sales charge is deducted
when a Contract Owner elects to receive the Commuted Value under the PAYMENTS
GUARANTEED FOR A SPECIFIED NUMBER OF YEARS Annuity Payment Option.
    
 
    In the event that surrender charges from the Contracts are not sufficient to
cover the expenses of selling the Contracts, Hartford will bear such expenses.
Conversely, if the revenue from such charges exceeds such expenses, the excess
of revenues from such charges over expenses will be retained by Hartford.

- --------------------------------------------------------------------------------
 
    The surrender charge is equal to a percentage of the Commuted Value (not to
exceed the Premium Payment) and is deducted from those values prior to their
being paid.

                               PREMIUM TAX CHARGE
 
   
    Certain states and municipalities impose a tax on Hartford in connection
with the Premium Payment or Contract Value. This tax can range from 0% to 4% of
either the Premium Payment or the Contract Value and is generally based on the
Contract Owner's state of residence. Taxes are generally incurred by Hartford as
of the Annuity Calculation Date. Hartford deducts the charge for taxes from the
Contract Value on the Annuity Calculation Date. Some jurisdictions impose a tax
on the Premium Payment at the time the Premium Payment is received. In those
jurisdictions, Hartford's current practice is to pay the tax on the Premium
Payment and then deduct the charge for these taxes from the Contract Value on a
surrender prior to Annuity Calculation Date, or on the Annuity Commencement
Date.
    
 
                       MORTALITY AND EXPENSE RISK CHARGE
 
    Hartford deducts a daily charge from the assets of the Separate Account to
compensate Hartford for mortality and expense risks that Hartford assumes under
the Contracts. The daily charge is at the rate of 0.003446% (approximately
equivalent to an effective annual rate of 1.25%) of the net assets of the
Separate Account. Approximately .90% of this annual charge is for the assumption
of mortality risk and .35% is for the assumption of expense risk.
 
    The mortality risk that Hartford assumes (for life contingency based Annuity
Payment Options) is the risk that Annuitants, as a group, will live for a longer
period of time than Hartford estimated when it established the annuity purchase
rates in the Contract. Because of these guarantees, each Contract Owner is
assured that the Annuitant's longevity will not have an adverse effect on the
Annuity Payments that the Payee receives under Annuity Payment Options based on
life contingencies. Hartford also assumes a mortality risk because the Contracts
guarantee a "death benefit" if the Contract Owner or Annuitant dies before the
Income Start Date.
 
                                 FUND EXPENSES
 
    The investment performance of each Fund reflects the management fee that the
Fund pays to its investment manager as well as other operating expenses that the
Fund incurs. Investment management fees are generally daily fees computed as a
percent of a Fund's average daily net assets at an annual rate. Please read the
prospectus for each Fund for complete details.
 
   
                        ADDITIONAL CONTRACT INFORMATION
    
 
                               CONTRACT OWNERSHIP
 
    The Contract belongs to the Contract Owner. A Contract Owner may exercise
all of the rights and options described in the Contract. Only the Annuitant may
be the owner of an IRA Contract.
 
    The Contract Owner's rights include the right to: (1) select or change the
Contract Owner, (2) select or change any Beneficiary or contingent Beneficiary,
(3) select or change the Payee while the Annuitant is still alive, (4) allocate
the Premium Payment among and between the Sub-Accounts, (5) transfer Contract
Value among and between the Sub-Accounts, and (6) exchange or transfer Annuity
Units between Sub-Accounts on which Variable Annuity Payments are based.
 
   
    The rights of owners of Qualified Contracts may be restricted by the terms
of a related employee benefit plan. For example, such plans may require an owner
of a Qualified Contract to obtain the consent of his or her spouse before
exercising certain ownership rights or may restrict withdrawals. See "Federal
Tax Considerations," page 20 for more details.
    
 
   
    Selection of an Annuitant or Payee who is not the Contract Owner may have
adverse tax consequences. See "Federal Tax Considerations," page 20 for more
details.
    
 
                   CHANGING THE CONTRACT OWNER OR BENEFICIARY
 
   
    At any time after the Cancellation Period, a Contract Owner may transfer
ownership of the Contract subject to Hartford's policies and procedures at the
time of the change.
    
 
    At any time prior to the death of the Annuitant, the Contract Owner may name
a new Beneficiary by Written Notice unless an irrevocable Beneficiary has
previously been named. When an irrevocable Beneficiary has been designated, the
Contract Owner must provide the irrevocable Beneficiary's written consent to
Hartford before a new Beneficiary is designated.

- --------------------------------------------------------------------------------
 
   
    These changes take effect as of the day the Written Notice was signed and
dated. Hartford is not liable for any payments made under the Contract prior to
the effectiveness of any change. For possible tax consequences of these changes,
see "Federal Tax Considerations," page 20.
    
 
                           MISSTATEMENT OF AGE OR SEX
    If an age or sex of the Annuitant given to Hartford (in the application or
otherwise) is misstated, Hartford will adjust the benefits it pays under the
Contract to the amount that would have been payable at the correct age or sex.
If Hartford made any underpayments because of any such misstatement, it shall
pay the amount of such underpayment to the Payee or Beneficiary in one sum. If
Hartford makes any overpayments because of a misstatement of age or sex, it
shall deduct from current or future payments due under the Contract, the amount
of such overpayment.
 
                            CHANGE OF CONTRACT TERMS
 
    Upon notice to the Contract Owner, Hartford may modify the Contract to:
 
1.  conform the Contract or the operations of Hartford or of the Separate
    Account to the requirements of any law to which the Contract, Hartford or
    the Separate Account is subject;
 
2.  assure continued qualification of the Contract as an annuity contract or a
    Qualified Contract under the Code;
3.  reflect a change (as permitted in the Contract) in the operation of the
    Separate Account.
 
    In the event of any such modification, Hartford will make appropriate
endorsements to the Contract.
 
    No modification of this Contract shall be made except over the signature of
the President, a Vice President, an Assistant Vice President or a Secretary of
Hartford. Any modification or waiver must be in writing. No agent may bind
Hartford by making any promise not contained in the Contract.
 
                           REPORTS TO CONTRACT OWNERS
 
    Hartford sends each Contract Owner a report at least annually, or more often
as required by law, indicating: the number of Accumulation or Annuity Units and
the dollar value of such units; the Contract Value prior to the Annuity
Calculation Date; the Premium Payment; or surrenders made before the Annuity
Calculation Date; Annuity Payments on or after the Income Start Date; and any
other information required by law.
 
    The reports, which are mailed to Contract Owners at their last known
address, include any information that may be required by the Commission or the
insurance supervisory official of the jurisdiction in which the Contract is
issued.
 
    Hartford also sends any other reports, notices or documents required by law
to be furnished to Owners.
 
                                 MISCELLANEOUS
 
    NON-PARTICIPATING. The Contract does not participate in the surplus or
profits of Hartford and Hartford does not pay dividends on the Contract.
 
    PROOF OF AGE AND SURVIVAL. Hartford reserves the right to require proof of
the Annuitant's age and gender prior to the Annuity Calculation Date. In
addition, Hartford reserves the right to require proof that the Annuitant is
living before any Income Payment Date.
 
   
    CONTRACT APPLICATION OR ORDER REQUEST. Hartford issues the Contract in
consideration of the Contract Owner's application or order request and Premium
Payment. The entire Contract is made up of the Contract and any attached
endorsements or riders. In the absence of fraud, Hartford considers statements
made in the application or order request to be representations and not
warranties. Hartford will not use any statement in defense of a claim or to void
the Contract unless it is contained in the application or order request.
Hartford will not contest the Contract.
    
 
                               VOTING PRIVILEGES
 
    In accordance with current interpretations of applicable law, Hartford votes
Fund shares held in the Separate Account at regular and special shareholder
meetings of the Funds in accordance with instructions received from persons
having voting interests in the corresponding Sub-Accounts.
 
    The number of votes that a Contract Owner has the right to instruct are
calculated separately for each Sub-Account, and may include fractional votes.
Prior to the Annuity Calculation Date, the Contract Owner holds a voting
interest in each Sub-Account to which Variable Contract Value is allocated.
After the Annuity Calculation Date, the Contract Owner has a voting interest in
each Sub-Account from which Variable Annuity Payments are made.
 
   
    For each Contract Owner prior to the Annuity Calculation Date, the number of
votes attributable to a Sub-Account will be determined by dividing the Contract
Owner's Sub-Account Value by the Net Asset Value of the Fund in which that
Sub-Account invests. For each Contract Owner after the Annuity Calculation Date,
the number of votes attributable to a Sub-Account is determined by dividing the
liability for future Variable Annuity Payments to be paid from that Sub-Account

Sub-Account invests. This liability for future payments is calculated on the
basis of the mortality assumptions, the selected Assumed Investment Return and
the Annuity Unit value of that Sub-Account. As Variable Annuity Payments are
made to the Payee, the liability for future payments decreases as does the
number of votes.
    
 
    The number of votes available to a Contract Owner are determined as of the
date coinciding with the date established by the Fund for determining
shareholders eligible to vote at the relevant meeting of the Fund's
shareholders. Voting instructions are solicited by written communication prior
to such meeting in accordance with procedures established for the Fund. Each
Contract Owner or Payee having a voting interest in a Sub-Account will receive
proxy materials and reports relating to any meeting of shareholders of the Funds
in which that Sub-Account invests.
 
    Fund shares as to which no timely instructions are received and shares held
by Hartford in a Sub-Account as to which no Owner or Payee has a beneficial
interest are voted in proportion to the voting instructions that are received
with respect to all Contracts participating in that Sub-Account. Voting
instructions to abstain on any item to be voted upon are applied to reduce the
total number of votes eligible to be cast on a matter.
 
   
                           FEDERAL TAX CONSIDERATIONS
    
 
                                    GENERAL
 
    TAX LAW IS COMPLEX AND TAX CONSEQUENCES WILL VARY ACCORDING TO THE ACTUAL
STATUS OF THE CONTRACT OWNER AND, IF APPLICABLE, THE TYPE OF RETIREMENT PROGRAM
FOR WHICH THE CONTRACT IS PURCHASED. THEREFORE, A PERSON, TRUSTEE OR OTHER
ENTITY CONTEMPLATING THE PURCHASE OF A CONTRACT MAY NEED LEGAL AND TAX ADVICE.
 
   
    This Prospectus does not provide a detailed description of the federal
income tax consequences of purchasing a Contract. Special tax rules may apply to
certain purchase situations not discussed herein. In addition, no attempt is
made here to consider any applicable state or other tax laws. For detailed
information, a prospective purchaser should always consult a qualified tax
adviser. This discussion is based on Hartford's understanding of existing
federal income tax laws as they are currently interpreted.
    
 
                            TAXATION OF HARTFORD AND
                              THE SEPARATE ACCOUNT
 
   
    The Separate Account is taxed as part of Hartford which is taxed as a life
insurance company under Subchapter L of Chapter 1 of the Internal Revenue Code
of 1986, as amended (the "Code"). Accordingly, the Separate Account is not
separately taxed as a "regulated investment company" under subchapter M of the
code. Investment income and any realized capital gains on the assets of the
Separate Account are reinvested and are taken into account in determining the
value of the Accumulation and Annuity Units. As a result, such investment income
and realized capital gains are automatically applied to increase reserves under
the Contract.
    
 
    No taxes are due on interest, dividends and short-term or long-term capital
gains earned by the Separate Account with respect to Qualified or Non-Qualified
Contracts.
 
                           TAXATION OF PURCHASERS OF
                            NON-QUALIFIED CONTRACTS
 
   
    CORPORATIONS, TRUSTS AND OTHER NON-NATURAL PERSONS. Section 72 of the Code
governs the taxation of annuity contracts and contains provisions relating to
non-natural Contract Owners. Non-natural persons include entities such as
corporations, trusts, and partnerships. In general, unless the non-natural
person holds a Contract as agent for a natural person, the annual net increase
in the value of the Contract is includable in the non-natural person's gross
income for the tax period in which the net increase occurs. There is, however,
an exception to this general rule for certain annuity contracts held by
structured settlement companies, certain annuity contracts held by an employer
with respect to a terminated qualified retirement plan and certain immediate
annuity contracts. For this purpose, an immediate annuity means an annuity that
is purchased with a single premium payment, that has an annuity start date
commencing no later than one year from the date of purchase, and that provides
for a series of substantially equal periodic payments to be made not less
frequently than annually during the annuity period. A non-natural person which
is a tax-exempt entity for federal income tax purposes is not subject to income
tax as a result of Section 72 of the Code.
    
 
    NATURAL PERSONS. Section 72 generally provides that a Contract Owner is not
taxed on increases in the value of the Contract until an amount distributed from
the Contract is received (or deemed received) by the Contract Owner, either in
the form of Annuity Payments, as contemplated by the Contract, or in some other
form (i.e., surrender or Death Benefit). However, this tax deferral generally
applies only if: (1) the investments in the Separate Account are "adequately
diversified" in accordance with Treasury Department regulations, (2) Hartford,
rather than the Contract Owner, is considered the owner of such assets for
federal income tax purposes, and (3) certain distribution requirements are met
in the event that the Contract Owner dies. These requirements are discussed
further under the caption "Tax Status of the Contract" below.
<PAGE>
HARTFORD LIFE AND ANNUITY INSURANCE COMPANY                                   21
- --------------------------------------------------------------------------------
 
    DISTRIBUTIONS PRIOR TO THE INCOME START DATE. The Contract does not permit
partial withdrawals or partial surrenders or loans. If, however, a Contract is
surrendered prior to the Income Start Date, amounts received by the Contract
Owner are includable in his or her income to the extent that such amounts exceed
the "investment in the contract." For this purpose, the investment in the
contract at any time equals the Premium Payment (to the extent that such Payment
was neither deductible when made nor excludable from income as, for example, in
the case of certain contributions to Qualified Contracts), less any amounts
previously received from the Contract which were not includable in income. Also,
the Surrender Value may be subject to a penalty tax, described below. In
general, an assignment of the Contract (or other change of ownership) without
full and adequate consideration will be treated as a distribution from the
Contract and taxed in the same manner as a surrender (except where the Contract
is transferred between spouses or incident to a divorce).
 
    The Contract provides that upon the death of Contract Owner, Annuitant or
Joint Annuitant, the Beneficiary will receive the Contract Value. This
distribution is includable in the Beneficiary's income as follows: (1) if
distributed in a lump sum, it is taxed in the same manner as a surrender, (2) if
it is distributed in the form of Annuity Payments, it is taxed in the same
manner as Annuity Payments (see below).
 
    DISTRIBUTIONS AFTER THE INCOME START DATE. The portion of each Annuity
Payment taxable as ordinary income is equal to the excess of the Annuity Payment
over the "exclusion amount." The "exclusion amount" is the investment in the
Contract (described above), adjusted for any guaranteed period, divided by the
number of Annuity Payments expected to be made (determined by Treasury
Department regulations that take into account the Annuitant's life expectancy
and the Annuity Payment Option elected). After the dollar amount of the
investment in the Contract, adjusted for any guaranteed period, is deemed to be
recovered, the entire amount of each Annuity Payment is fully includable in
income. Nonetheless, should the Annuity Payments cease before the adjusted
investment in the Contract is fully recovered, a deduction is allowed for the
unrecovered amount of the adjusted investment in the Contract. Where a
guaranteed period of Annuity Payments is selected and the Annuitant does not
live to the end of that period, the Annuity Payments for the remainder of the
period are includable in income as follows: (1) if distributed in a lump sum,
they are included in income to the extent that they exceed the unrecovered
investment in the Contract at that time, or (2) if received as Annuity Payments,
they are fully excluded from income until the remaining investment in the
Contract is deemed to be recovered. All Annuity Payments thereafter are fully
includable in income.
 
    PENALTY TAX ON CERTAIN DISTRIBUTIONS. Distributions received (or deemed
received) from a Contract (before or after the Income Start Date) may be subject
to a penalty tax equal to 10% of the amount treated as taxable income. In
general, however, there is no penalty tax on distributions:
 
   
1.  made on or after a taxpayer reaches age 59 1/2;
    
 
2.  made on or after the death of the Contract Owner;
 
3.  attributable to a taxpayer's becoming disabled;
 
4.  that are part of a series of substantially equal periodic payments (not less
    frequently than annually) for the life (or the life expectancy) of the
    taxpayer or the joint lives (or joint life expectancies) of the taxpayer and
    his or her designated beneficiary;
 
5.  made under certain annuities issued in connection with structured settlement
    agreements; and
 
6.  made under an annuity contract that is purchased with a single premium
    payment when the annuity date is no later than a year from purchase and
    substantially equal periodic payments are made, not less frequently than
    annually, during the annuity payment period.
 
   
    AGGREGATION OF TWO OR MORE CONTRACTS. All non-qualified deferred annuity
contracts issued by Hartford (or its affiliates) to the same owner during a
calendar year are treated as one annuity contract for purposes of determining
the amount includable in gross income under Section 72(e) of the Code. The
effects of this rule are not yet clear; however, it could affect the time when
income is taxable and the amount that might be subject to the 10% penalty tax
described above. In addition, the Treasury Department has specific authority to
issue regulations that prevent the avoidance of Section 72(e) of the Code
through the serial purchase of annuity contracts or otherwise. There may also be
other situations in which the Treasury Department may conclude that it would be
appropriate to aggregate two or more deferred or immediate annuity contracts
purchased by the same owner. Accordingly, a Contract Owner should consult a
competent tax adviser before purchasing more than one annuity contract in a
calendar year.
    
 
   
    POSSIBLE CHANGES IN TAXATION. In past years, legislation has been proposed
that would have adversely modified the federal taxation of certain annuity
contracts. For example, one such proposal would have changed the tax treatment
of non-qualified annuities that did not have "substantial life contingencies" by
taxing income as it is credited to the annuity contract. There is always the
possibility that the tax treatment of annuities could change by legislation or
other means (such as IRS regulations, revenue rulings, judicial decisions,
etc.). Moreover, it is also possible that any change could be retroactive (that
is, effective prior to the date of the change).
    
 
    CONTRACTS OBTAINED THROUGH A TAX-FREE EXCHANGE OF OTHER ANNUITY OR LIFE
INSURANCE CONTRACTS. Section 1035 of the Code generally provides that no gain or
loss shall be recognized on the exchange of one annuity contract for another. If
the
<PAGE>

- --------------------------------------------------------------------------------
 
   
surrendered contract was issued prior to August 14, 1982, the tax rules formerly
provided that the surrender was taxable only to the extent the amount received
exceeds the owner's investment in the contract will and continue to apply to
amounts allocable to investments in that contract prior to August 14, 1982. In
contrast, contracts issued after January 19, 1985 in a Code Section 1035
exchange are treated as new contracts for purposes of the penalty and
distribution-at-death rules. Special rules and procedures apply to Section 1035
transactions. Prospective Contract Owners desiring to take advantage of Section
1035 should consult their tax adviser.
    
 
    TAX STATUS OF THE CONTRACTS. The foregoing discussion assumes that the
Contracts qualify as "annuity contracts" for federal income tax purposes under
the Code.
 
    DIVERSIFICATION REQUIREMENTS. Section 817(h) of the Code provides that
separate account investments underlying a contract must be "adequately
diversified" in accordance with Treasury Department regulations in order for the
contract to qualify as an annuity contract under Section 72 of the Code. The
Separate Account, through each underlying Fund, intends to comply with the
diversification requirements prescribed in regulations under Section 817(h) of
the Code, which affect how the assets in the various Sub-Accounts may be
invested. Although Hartford does not have direct control over the Funds in which
the Separate Account invests, Hartford believes that each Fund will meet the
diversification requirements, and therefore, the Contract will be treated as an
annuity contract under the Code.
 
    The Treasury Department has issued diversification regulations which
generally require, in effect, among other things, that no more than 55% of the
value of the total assets of each Fund is represented by any one investment, no
more than 70% is represented by any two investments, no more than 80% is
represented by any three investments, and no more than 90% is represented by any
four investments. In determining whether the diversification standards are met,
all securities of the same issuer, all interests in the same real property
project, and all interests in the same commodity are each treated as a single
investment. In addition, in the case of government securities, each government
agency or instrumentality shall be treated as a separate issuer.
 
   
    In certain circumstances, owners of variable annuity contracts may be
considered the owners, for federal income tax purposes, of the assets of the
separate account used to support their contracts. In those circumstances, income
and gains from the separate account assets would be includable in the variable
annuity contract owner's gross income. The IRS has stated in published rulings
that a variable contract owner will be considered the owner of separate account
assets if the contract owner possesses certain incidents of ownership in those
assets, such as the ability to exercise investment control over the assets. The
Treasury Department has also announced, in connection with the issuance of
regulations concerning investment diversification, that those regulations "do
not provide guidance concerning the circumstances in which investor control of
the investments of a segregated asset account may cause the investor (i.e., the
contract owner), rather than the insurance company, to be treated as the owner
of the assets in the account." This announcement also states that guidance would
be issued by way of regulations or rulings on the "extent to which policyholders
may direct their investments to particular Sub-Accounts without being treated as
owners of the underlying assets." As of the date of this Prospectus, no such
guidance has been issued.
    
 
    The ownership rights under the Contracts are similar to, but different in
certain respects from, those described by the IRS in rulings in which it was
determined that contract owners were not owners of separate account assets. For
example, the Contract Owner has the choice of several Sub-Accounts in which to
allocate the Premium Payment and Contract Value, and may be able to transfer
Contract Value among Sub-Accounts more frequently than in such rulings. In
addition, the Contract provides for more Sub-Accounts than did the variable
contracts that were the subject of the such rulings. These differences could
result in a Contract Owner being treated as the owner of the assets of the
Separate Account. In addition, Hartford does not know what standards will be set
forth, if any, in the regulations or rulings which the Treasury Department has
stated it expects to issue. Hartford therefore reserves the right to modify the
Contract as necessary to attempt to prevent the Contract Owner from being
considered the owner of the Separate Account's assets.
 
    REQUIRED DISTRIBUTIONS. In order to be treated as an annuity contract for
federal income tax purposes, Section 72(s) of the Code requires any
Non-Qualified Contract to provide that: (a) if any Contract Owner dies on or
after the Income Start Date but prior to the time the entire interest in the
Contract has been distributed, the remaining portion of such interest will be
distributed at least as rapidly as under the method of distribution being used
as of the date of that Contract Owner's death; and (b) if any Contract Owner
dies prior to the Income Start Date, the entire interest in the Contract will be
distributed within five years after the date of the Contract Owner's death.
These requirements will be considered satisfied as to any portion of the
Contract Owner's interest that is payable to or for the benefit of a "designated
beneficiary," and that is distributed over the life of such Beneficiary or over
a period not extending beyond the life expectancy of that Beneficiary, provided
that such distributions begin within one year of that Contract Owner's death.
The Contract Owner's "designated beneficiary" is the person designated by such
Contract Owner as a Beneficiary and must be a natural person. However, if the
Contract Owner's sole designated beneficiary is the surviving spouse of the
Contract Owner, the Contract may be continued with
<PAGE>
HARTFORD LIFE AND ANNUITY INSURANCE COMPANY                                   23
- --------------------------------------------------------------------------------
 
   
the surviving spouse as the new Contract Owner. The requirements further provide
that if the Contract Owner is not an individual, the primary Annuitant shall be
treated as the Contract Owner for purposes of making distributions that are
required to be made upon the death of the Contract Owner. If there is a change
in the primary Annuitant, such change shall be treated as the death of the
Contract Owner. The Contract does not permit a change of the Annuitants.
    
 
    Non-Qualified Contracts contain provisions that are intended to comply with
the requirements of Section 72(s) of the Code, although no regulations
interpreting these requirements have yet been issued. Hartford will review such
provisions and modify them if necessary to assure that they comply with the
requirements of Code Section 72(s) when clarified by regulation or otherwise.
 
                           TAXATION OF PURCHASERS OF
                              QUALIFIED CONTRACTS
 
   
    The Contracts are designed for use as IRAs or in connection with Deferred
Compensation Plans established and maintained by state or local governments or
tax-exempt organizations. Important differences exist between the tax rules
which are applicable to IRAs and Deferred Compensation Plans. These rules are
complex and may vary depending on individual circumstances. Adverse tax
consequences may result from distributions prior to age 59 1/2 (subject to
certain exceptions); distributions that do not conform to applicable
commencement and minimum distribution rules; aggregate distributions in excess
of a specified annual amount; and in other circumstances. Therefore, no attempt
is made to provide more than general information about the use of the Contracts
as IRAs or when owned by eligible employers in connection with Deferred
Compensation Plans. Contract Owners, Annuitants, and Beneficiaries are cautioned
that the rights of any person to any benefits under a Deferred Compensation Plan
may be subject to the terms and conditions of the plan itself, regardless of the
terms and conditions of the Contract, but that Hartford is not bound by the
terms and conditions of such plans to the extent such terms conflict with the
Contract, unless Hartford specifically consents to be bound. A brief description
of some of the federal income tax rules which apply to IRAs and Deferred
Compensation Plans is set forth below. Hartford may amend the Contract as
necessary to conform it to the requirements of applicable law.
    
 
    INDIVIDUAL RETIREMENT ANNUITIES. The Contract is designed for use as an IRA
purchased through a tax-deferred rollover contribution from another IRA, a
retirement plan qualified under Section 401 or Section 403(a) of the Code or tax
sheltered annuity contract under Section 403(b) of the Code. Amounts held under
a Deferred Compensation Plan under Section 457 of the Code CANNOT be rolled over
or transferred to an IRA.
 
   
    DISTRIBUTIONS FROM AN IRA. In general, payments from an IRA which are not
rolled over must be included in gross income as ordinary taxable income in the
year in which they are received. Required minimum distributions must begin by
April 1 of the calendar year following the calendar year in which the IRA owner
attains the age of 70 1/2. Certain other mandatory distribution rules apply upon
the death of the IRA owner.
    
 
   
    TEN PERCENT PENALTY TAX ON EARLY DISTRIBUTIONS. Distributions from an IRA
may be subject to a penalty tax equal to ten percent (10%) of the amount treated
as taxable income. In general, however, there is no such penalty tax on
distributions:
    
 
   
1.  made on or after the date on which the taxpayer reaches age 59 1/2,
    
 
2.  made to a beneficiary (or to the estate of the taxpayer) on or after the
    death of the taxpayer,
 
   
3.  attributable to the taxpayer's becoming disabled,
    
 
   
4.  which are part of a series of substantially equal periodic payments (not
    less frequently than annually) made for the life (or life expectancy) of the
    taxpayer or the joint lives (or joint life expectancies) of the taxpayer and
    his or her designated beneficiary,
    
 
5.  made to the taxpayer to the extent such distributions do not exceed the
    amount allowable as a deduction for federal income tax purposes allowed to
    the taxpayer for amounts paid during the taxable year for medical care, or
 
6.  if certain conditions are met, made to an unemployed taxpayer after
    separation from employment, for health insurance premiums.
 
   
    In addition, effective for distributions made from an IRA after December 31,
1997, there is no such penalty for distributions:
    
 
   
7.  made to the taxpayer to the extent the distribution does not exceed the
    amount of certain qualifying higher education expenses, as defined by
    section 72 (t) (7) of the Code, or
    
 
   
8.  which are qualified first-time home buyer distributions meeting the
    requirements specified at section 72 (t) (8) of the Code.
    
 
   
    CODE SECTION 457 DEFERRED COMPENSATION PLANS. The Contracts may be purchased
by a state or local government or tax-exempt organization that is an employer
sponsoring a Deferred Compensation Plan under Section 457 of the Code in order
to effect distribution of plan benefits to participants under the plan. In
general, distributions from a Deferred Compensation Plan are prohibited under
Section 457 unless made after the participant attains age 70 1/2 specified in
the plan, separates from service, dies, or suffers an unforeseeable financial
emergency. Distributions under
    
<PAGE>

- --------------------------------------------------------------------------------
 
plans that meet the requirements of Section 457 of the Code are taxable as
ordinary income in the year paid or made available to the participant or
beneficiary.
 
    Generally, required minimum distributions must begin by April 1 of the
calendar year following the calendar year in which the participating employee
attains the age of 70 1/2. Certain other mandatory distribution rules apply upon
the death of the participating employee.
 
    Amounts held under a Deferred Compensation Plan under Section 457 of the
Code CANNOT be rolled over or transferred to an IRA.
                         FEDERAL INCOME TAX WITHHOLDING
 
    The portion of a distribution from a Contract that is taxable income to the
recipient is generally subject to withholding for the recipient's federal income
tax liability at rates that vary according to the type of distribution and the
recipient's tax status. Section 3405 of the Code governs withholding and is
summarized below:
 
    NON-PERIODIC DISTRIBUTIONS. The portion of a non-periodic distribution which
constitutes taxable income will be subject to federal income tax withholding
unless the recipient elects not to have taxes withheld. If an election not to
have taxes withheld is not provided, 10% of the taxable distribution will be
withheld as federal income tax. Election forms will be provided at the time
distributions are requested. If the necessary election forms are not submitted
to Hartford, Hartford will automatically withhold 10% of the taxable
distribution.
    PERIODIC DISTRIBUTIONS (DISTRIBUTIONS PAYABLE OVER A PERIOD GREATER THAN ONE
YEAR). The portion of a periodic distribution which constitutes taxable income
will be subject to federal income tax withholding as if the recipient were
married claiming three exemptions. A recipient may elect not to have income
taxes withheld or have income taxes withheld at a different rate by providing a
completed election form. Election forms will be provided at the time
distributions are requested.
 
    DEFERRED COMPENSATION PLANS. Distributions from a non-qualified deferred
compensation plan meeting the requirements of Section 457 of the Code are
generally subject to regular wage withholding rules. Certain states also require
withholding of state income tax whenever federal income tax is withheld.
 
                      CONTRACT OWNERS THAT ARE NONRESIDENT
                         ALIENS OR FOREIGN CORPORATIONS
 
    The discussion above provides general information regarding U.S. federal
income tax consequences to Contract Owners that are U.S. citizens or residents.
Purchasers that are not U.S. citizens or residents will generally be subject to
U.S. federal income tax and withholding on annuity distributions at a 30% rate,
unless a lower treaty rate applies and any required tax forms are submitted to
Hartford. In addition, purchasers may be subject to state premium tax, other
state and/or municipal taxes, and taxes that may be imposed by the purchaser's
country of citizenship or residence. Prospective purchasers are advised to
consult with a qualified tax adviser regarding U.S., state, and foreign taxation
with respect to the purchase of a Contract.
 
                             OTHER TAX CONSEQUENCES
 
   
    As noted above, the foregoing comments about the federal tax consequences
under these Contracts are not exhaustive, and special rules may apply to other
tax situations not discussed in the Prospectus. Further, the federal income tax
consequences discussed herein reflect Hartford's understanding of current law
which is subject to change. Federal, state and local gift estate, inheritance
and other tax consequences of ownership or receipt of distributions under a
Contract depend on the individual circumstances of each Contract Owner or
recipient of the distribution. In particular, certain gift and/or estate tax
consequences may result in situations where the Contract Owner is not also the
Annuitant, Payee, and Beneficiary. A competent tax adviser should be consulted
for further information.
    
 
   
                               OTHER INFORMATION
    
 
                         DISTRIBUTION OF THE CONTRACTS
 
    Hartford Securities Distribution Company, Inc. ("HSD"), which is located at
200 Hopmeadow Street, Simsbury, CT 06070, is principal underwriter and
distributor of the Contracts. HSD is an affiliate of Hartford, is registered
with the Commission as a broker-dealer, and is a member of the National
Association of Securities Dealers, Inc. Hartford pays HSD for acting as
principal underwriter under a distribution agreement. The Contracts are offered
on a continuous basis and Hartford does not anticipate discontinuing the offer.
 
   
    Applications for Contracts are solicited by agents who are licensed by
applicable state insurance authorities to sell Hartford's insurance contracts
and who are also registered representatives of a broker-dealer having a selling
agreement with HSD. Such broker-dealers will generally receive commissions based
on a percent of Premium Payment made (up to a maximum of 6%). The writing agent
will receive a percentage of these commissions from the respective
broker-dealer, depending on the practice of that broker-dealer. Contract Owners
do not pay these commissions.

- --------------------------------------------------------------------------------
 
   
    Broker-dealers or financial institutions are compensated according to a
schedule set forth by HSD and any applicable rules or regulations for variable
insurance compensation. Compensation is generally based on premium payments made
by policyholders or contract owners. This compensation is usually paid from the
sales charges described in this Prospectus.
    
 
   
    In addition, a broker-dealer or financial institution may also receive
additional compensation for, among other things, training, marketing or other
services provided. HSD, its affiliates or Hartford may also make compensation
arrangements with certain broker-dealers or financial institutions based on
total sales by the broker-dealer or financial institution of insurance products.
These payments, which may be different for different broker-dealers or financial
institutions, will be made by HSD, its affiliates or Hartford out of their own
assets and will not effect the amounts paid by the policyholders or contract
owners to purchase, hold or surrender variable insurance products.
    
 
                               LEGAL PROCEEDINGS
 
    There are no legal proceedings to which the Separate Account is a party or
to which the assets of the Separate Account are subject.

The following graph has been prepared to show how investment performance could
affect Variable Annuity Payments over time. The graph illustrates the Variable
Annuity Payments of a Non-Qualified Contract under three hypothetical rate of
return scenarios. Of course, the illustrations merely represent what Variable
Annuity Payments might be paid under a HYPOTHETICAL Non-Qualified Contract.
    
 
   
    WHAT THE GRAPHS ILLUSTRATE. Each curve plotted on the graph illustrates the
payments under a hypothetical Non-Qualified Contract (described in more detail
below) assuming a different hypothetical rate of return for a single Sub-Account
supporting the Contract by plotting one point for each contract year. Each such
annual point on the graph represents the average of twelve monthly Variable
Annuity Payments made in that contract year under the hypothetical Contract
(hereinafter, an "Average Monthly Payment"). Each curve on the graph assumes
that the initial Variable Annuity Payment under the hypothetical Contract is
$1,000 (discussed in more detail below).
    
 
   
    HYPOTHETICAL RATES OF RETURN. The Variable Annuity Payments reflect three
different assumptions for a constant investment return before fees and expenses:
0%, 6% and 12%. Net of all expenses, these constant returns are: -1.83%, 4.06%
and 9.95%. Average Monthly Payments reflect the assumed investment return net of
all expenses of the illustrated Sub-Account (and the Funds) over the periods
shown in each graph. Fund management fees and operating expenses are assumed to
be at an annual rate of 0.60% of their average daily net assets. This is the
weighted average of Fund expenses shown in the fee table on page 5. The
mortality and expense risk charge is assumed to be at an annual rate of 1.25% of
the illustrated Sub-Account's average daily net assets.
    
 
   
    Nevertheless, THE AVERAGE MONTHLY PAYMENTS DEPICTED IN THE GRAPH ARE BASED
ON HYPOTHETICAL CONTRACTS AND HYPOTHETICAL INVESTMENT RESULTS AND ARE NOT
PROJECTIONS OR INDICATIONS OF FUTURE RESULTS. HARTFORD DOES NOT GUARANTEE OR
EVER SUGGEST THAT ANY SUB-ACCOUNT OR CONTRACT ISSUED BY IT WOULD GENERATE THESE
OR SIMILAR AVERAGE MONTHLY PAYMENTS FOR ANY PERIOD OF TIME. THE GRAPHS ARE FOR
ILLUSTRATION PURPOSES ONLY AND DO NOT REPRESENT FUTURE VARIABLE ANNUITY PAYMENTS
OR FUTURE INVESTMENT RETURNS. Variable Annuity Payments under a real Contract
may be more or less than those forming the basis for the Average Monthly
Payments shown in these illustrations if the actual returns of the Sub-Accounts
selected by a Contract Owner are different from the hypothetical returns.
Because it is very likely that a Sub-Account's investment return will fluctuate
over time, one can expect Variable Annuity Payments under a real Contract to
fluctuate. Moreover, under a real Contract, the total amount of Variable Annuity
Payments ultimately received by a Payee depends upon which Annuity Payment
Option the Contract Owner selects and, for life contingent annuity payment
options, how long the Annuitant lives. (See "Selecting an Annuity Payment
Option" on page 15.)
    
 
    ASSUMPTIONS ON WHICH THE HYPOTHETICAL CONTRACT IS BASED. In order to
illustrate a hypothetical Contract, Hartford had to make several assumptions
about the Contract. These assumptions are that: (1) the hypothetical Contract is
a Non-Qualified Contract, (2) the entire Contract Value of the hypothetical
Contract is allocated (on the Annuity Calculation Date) to a Sub-Account having
a constant investment return before fees and expenses of 0%, 6%, or 12%, (3) the
Contract Owner selected an Assumed Investment Return of 5%, (4) the Contract
Owner elects to receive monthly Variable Annuity Payments, and (5) the Contract
Value (less any applicable Premium Tax) applied to the purchase of Annuity Units
on the Annuity Calculation Date under the Annuity Payment Option selected
results in an initial Variable Annuity Payment of $1,000.
 
   
    For a discussion of how a Contract Owner may elect to receive monthly,
quarterly, semi-annual or annual Variable Annuity Payments, see "Income Payment
Dates," page 16.
    
 
   
    ASSUMED INVESTMENT RETURN. Among the most important facts that determine
that amount of Variable Annuity Payments is the Assumed Investment Return
selected by the Contract Owner. The hypothetical Contract has an Assumed
Investment Return of 5%. Subject to state approval, a Contract Owner may,
however, select a 3%, 5% or 6% Assumed Investment Return under a real Contract.
Generally, Variable Annuity Payments will increase in size from one Income
Payment Date to the next if the annualized net rate of return during that time
is greater than the Assumed Investment Return, and will decrease if the
annualized net rate of return over this period is less than the Assumed
Investment Return. (The Assumed Investment Return is an important component of
the Payment Factor.) For a detailed discussion of Assumed Investment Returns,
see "Variable Annuity Payments," page 16.
    
 
   
    THE $1,000 INITIAL ANNUITY PAYMENT. The hypothetical Contract has an initial
Variable Annuity Payment of $1,000. The dollar amount of the first Variable
Annuity Payment under a real Contract generally depends upon the Annuity Payment
Option selected by the Contract Owner, the amount of Contract Value applied to
purchase the Variable Annuity Payments, the annuity purchase rates in the
Contract at the time it is purchased (i.e., the Payment Factor), the age of the
Annuitant, and, in most cases (e.g., Non-Qualified Contracts), the sex of the
Annuitant. For each of the illustrations, the entire Contract Value under the
hypothetical Contract is allocated to a Sub-Account

having a constant investment return before fees and expenses of 0%, 6%, or 12%.
However, for a real Contract, Contract Value is often allocated among several
Sub-Accounts prior to the Annuity Calculation Date. The dollar amount of the
first Variable Annuity Payment attributable to each Sub-Account is determined
under a real Contract by dividing the dollar amount of Contract Value (less
applicable Premium Tax) applied to that Sub-Account on the Annuity Calculation
Date by $1,000, and multiplying the result by the annuity Payment Factor in the
Contract for the selected Annuity Payment Option. The dollar value of the first
Variable Annuity Payment is the sum of the first Variable Annuity Payments
attributable to each Sub-Account. For a detailed discussion of how the first
Variable Annuity Payment is determined, see "Variable Annuity Payments," page
16.

                       ILLUSTRATIONS OF ANNUITY PAYMENTS
                         USING HISTORIC RATES OF RETURN
    
 
   
The following graphs have been prepared to show how investment performance
affects Variable Annuity Payments over time. These graphs illustrate the
"performance" of a Non-Qualified Contract under which Variable Annuity Payments
begin at the end of the month that the Contract was issued which is the same
month that each Sub-Account illustrated began operations. Of course, Hartford
did not sell Contracts prior to the date of this Prospectus (i.e., during any of
the time periods shown) and therefore the illustrations merely represent what
Variable Annuity Payments might have been under a HYPOTHETICAL Non-Qualified
Contract had one existed during the years shown.
    
 
   
    WHAT THE GRAPHS ILLUSTRATE. Each graph illustrates the "performance" of a
particular Sub-Account based on hypothetical Non-Qualified Contract (described
in more detail below) by plotting one point for each calendar year since the
Sub-Account began operations. Each such annual point on the graph represents the
average of twelve monthly Variable Annuity Payments made in that year under the
hypothetical Contract. Each graph assumes that the initial Variable Annuity
Payment under the hypothetical Contract is $1,000 (discussed in more detail
below). All of the graphs end on December 31, 1997. Where a Sub-Account began
operations in mid-year, the point for the first year represents the average of
monthly Variable Annuity Payments made (which is fewer than 12) under the
hypothetical Contract during that year. The points therefore represent, in each
case, the average monthly Variable Annuity Payment (hereinafter, an "Average
Monthly Payment").
    
 
   
    Average Monthly Payments reflect the actual past investment return after all
expenses of the Sub-Accounts over the periods shown in each graph. Nevertheless,
THE AVERAGE MONTHLY PAYMENTS DEPICTED IN THE GRAPHS ARE BASED ON HYPOTHETICAL
CONTRACTS AND PAST INVESTMENT RESULTS AND ARE NOT PROJECTIONS OR INDICATIONS OF
FUTURE RESULTS. HARTFORD DOES NOT GUARANTEE OR EVEN SUGGEST THAT ANY CONTRACT
ISSUED BY IT WOULD GENERATE THESE OR SIMILAR VARIABLE ANNUITY PAYMENTS FOR ANY
PERIOD OF TIME. THE GRAPHS ARE FOR ILLUSTRATION PURPOSES ONLY AND DO NOT
REPRESENT FUTURE VARIABLE ANNUITY PAYMENTS OR FUTURE INVESTMENT RETURNS.
Variable Annuity Payments under a real Contract may be more or less than those
forming the basis for the Average Monthly Payments shown in these illustrations
if the actual returns of the Sub-Accounts selected by a Contract Owner are
different from the past returns of the Sub-Accounts. Because it is very likely
that a Sub-Account's investment return will fluctuate over time, one can expect
Variable Annuity Payments under a real Contract to fluctuate. Moreover, under a
real Contract, the total amount of Variable Annuity Payments ultimately received
by a Payee depends upon which Annuity Payment Option the Contract Owner selects
and, for life contingent annuity options, how long the Annuitant lives. (See
"Selecting an Annuity Payment Option," page 15.)
    
 
   
    ASSUMPTIONS ON WHICH THE HYPOTHETICAL CONTRACT IS BASED. In order to
illustrate a hypothetical Contract, Hartford had to make several assumptions
about the Contract. These assumptions are that: (1) the hypothetical Contract is
a Non-Qualified Contract, (2) the entire Contract Value of the hypothetical
Contract is allocated (on the Annuity Calculation Date) to the Sub-Account being
illustrated, (3) the Contract Owner selected an Assumed Investment Return of 5%,
(4) the Contract Owner elects to receive monthly Variable Annuity Payments and
elects an Income Start Date that is the last day of the month in which the
Contract was issued, (5) the Contract Value (less any applicable premium tax)
applied to the purchase of Annuity Units on the Annuity Calculation Date under
the Annuity Payment Option selected results in an initial Variable Annuity
Payment of $1,000, and (6) the Income Start Date is the last day of the month
that the Sub-Account illustrated began operations. TO THE EXTENT THAT A REAL
CONTRACT IS ISSUED BY HARTFORD ON A BASIS DIFFERENT FROM THE FOREGOING
ASSUMPTIONS, THAT REAL CONTRACT WOULD HAVE HAD AVERAGE MONTHLY PAYMENTS
DIFFERENT FROM THOSE ILLUSTRATED EVEN DURING THE PERIODS ILLUSTRATED.
    
 
   
    For a discussion of how a Contract Owner may elect to receive monthly,
quarterly, semi-annual or annual Variable Annuity Payments, see "Income Payment
Dates," page 16.
    
 
   
    ASSUMED INVESTMENT RETURN. Among the most important facts that determine
that amount of Variable Annuity Payments is the Assumed Investment Return
selected by the Contract Owner. The hypothetical Contract has an Assumed
Investment Return of 5%. Subject to state approval, a Contract Owner may,
however, select a 3%, 5% or 6% Assumed Investment Return under a real Contract.
Generally, Variable Annuity Payments will increase in size from one Income
Payment Date to the next if the annualized net rate of return during that time
is greater than the Assumed Investment Return, and will decrease if the
annualized net rate of return over this period is less than the Assumed
Investment Return. (The Assumed Investment Return is an important component of
the Payment Factor.) For a detailed discussion of Assumed Investment Returns,
see "Variable Annuity Payments," page 16. Standardized and non-standardized
average annual total returns as well as the Sub-Account Annual Percentage Change
column reflect the performance of the Sub-Account being illustrated without
adjustment for an Assumed Investment Return.
    
 
   
    THE $1,000 INITIAL ANNUITY PAYMENT. The hypothetical Contract has an initial
Variable Annuity Payment of $1,000.

The dollar amount of the first Variable Annuity Payment under a real Contract
generally depends upon the Annuity Payment Option selected by the Contract
Owner, the amount of Contract Value applied to purchase the Variable Annuity
Payments, the annuity purchase rates in the Contract at the time it is purchased
(i.e., the Payment Factor), the age of the Annuitant, and, in most cases (e.g.,
Non-Qualified Contracts), the sex of the Annuitant. For each of the
illustrations, the entire Contract Value under the hypothetical Contract is
allocated to the Sub-Account shown in the illustrations. However, for a real
Contract, Contract Value is often allocated among several Sub-Accounts prior to
the Annuity Calculation Date. The dollar amount of the first Variable Annuity
Payment attributable to each Sub-Account is determined under a real Contract by
dividing the dollar amount of Contract Value (less applicable Premium Tax)
applied to that Sub-Account on the Annuity Calculation Date by $1,000, and
multiplying the result by the annuity Payment Factor in the Contract for the
selected Annuity Payment Option. The dollar value of the first Variable Annuity
Payment is the sum of the first Variable Annuity Payments attributable to each
Sub-Account. For a detailed discussion of how the first Variable Annuity Payment
is determined, see "Variable Annuity Payments," page 16.

 * Fund inception was 3/95. Therefore, the Average Monthly Payment represents
   the average monthly payment from March 1995 to December 1995. The Annual
   Sub-Account Return is based on the period from March 1995 to December 1995.
** Standardized Average Annual Total Returns differ from Non-Standardized
   Average Annual Total Returns in that the former reflect a deduction for the
   Contingent Deferred Sales Charge where the latter do not.

                           CALCULATION OF YIELD AND RETURN

YIELD OF THE MONEY MARKET  FUND SUB-ACCOUNT  
    

   
As summarized in the Prospectus under the heading "Performance Related
Information," the yield of the Money Market  Fund Sub-Account for a seven day
period (the "base period") will be computed by determining the "net change in
value" (calculated as set forth below) of a hypothetical account having a
balance of one accumulation unit of the Sub-Account at the beginning of the
period, subtracting a hypothetical charge reflecting deductions from Contract
Owner accounts, and dividing the difference by the value of the account at the
beginning of the base period to obtain the base period return, and then
multiplying the base period return by 365/7 with the resulting yield figure
carried to the nearest hundredth of one percent.  Net changes in value of a
hypothetical account will include net investment income of the account (accrued
daily dividends as declared by the underlying funds, less daily expense charges
of the account) for the period, but will not include realized gains or losses or
unrealized appreciation or depreciation on the underlying fund shares.
    

                                          2
<PAGE>

The effective yield is calculated by compounding the base period return by
adding 1, raising the sum to a power equal to 365/7 and subtracting 1 from the
result, according to the following formula:

Effective Yield = [(Base Period Return + 1) 365/7] - 1
The Money Market  Fund Sub-Account's yield and effective yield will vary in
response to fluctuations in interest rates and in the expenses of the
Sub-Account.

THE CURRENT YIELD AND EFFECTIVE YIELD REFLECT RECURRING CHARGES ON THE SEPARATE
ACCOUNT LEVEL.


   
MONEY MARKET  FUND SUB-ACCOUNT

The yield and effective yield for the seven day period ending December 31, 1997
for the Money Market  Fund Sub-Account was as follows:
    


   
<TABLE>

<S>                  <C>
Yield                4.11%
Effective Yield      4.20%

</TABLE>
    

   
YIELDS OF THE BOND  FUND AND MORTGAGE SECURITIES  FUND SUB-ACCOUNTS  

As summarized in the Prospectus under the heading "Performance Related
Information," yields of these two Sub-Accounts will be computed by annualizing a
recent month's net investment income, divided by a Fund share's net asset value
on the last trading day of that month.  The Bond  Fund and  Mortgage Securities 
Fund Sub-Accounts' yields will vary from time to time depending upon market
conditions and, the composition of the underlying funds' portfolios.  Yield
should also be considered relative to changes in the value of the Sub-Accounts'
shares and to the relative risks associated with the investment objectives and
policies of the Bond  Fund and Mortgage Securities  Fund.
    

THE YIELD REFLECTS RECURRING CHARGES ON THE SEPARATE ACCOUNT LEVEL.


   
BOND  FUND AND 
MORTGAGE SECURITIES  FUND SUB-ACCOUNTS

Yield calculations of the Sub-Accounts used for illustration purposes reflect
the interest earned by the Sub-Accounts, less applicable asset charges assessed
against a Contract Owner's account over the base period.  Yield quotations based
on a 30 day period ended December 31, 1997 were computed by dividing the
dividends and interests earned during the period by the maximum offering price
per unit on the last day of the period, according to the following formula:
    

Example:
                                                             6
Current Yield Formula for the Sub-Account  2[((A-B)/(CD) + 1)  - 1]

Where     A = Dividends and interest earned during the period.
          B = Expenses accrued for the period (net of reimbursements).
          C = The average daily number of units outstanding during the period 
                    that were entitled to receive dividends.
          D = The maximum offering price per unit on the last day of the period.

Bond  Fund
     Yield =  5.02 %

Mortgage Securities Fund
     Yield =  5.34 %
    

At any time in the future, yields and total return may be higher or lower than
past yields and there can be no assurance that any historical results will
continue.

CALCULATION OF TOTAL RETURN  

   
As summarized in the Prospectus under the heading "Performance Related
Information," total return is a measure of the change in value of an investment
in a Sub-Account over the period covered.  The formula for total return used
herein includes three steps: (1) calculating the value of the hypothetical
initial investment of $1,000 as of the end of the period by multiplying the
total number of units owned at the end of the period by the unit value per unit
on the last trading day of the period; (2) assuming redemption at the end of the
period and deducting any applicable contingent deferred sales charge (the
contingent deferred sales charge deducted under the "Since Inception" column
below depends on the fund inception date; 6% is deducted for 1 Year, 4% for 5
Year, and 0% for 10 Year periods) and (3) dividing this account value for the
hypothetical investor by the initial $1,000 investment and annualizing the
result for periods of less than one year.  Total return will be calculated for
one year, five years and ten years or some other relevant periods if a
Sub-Account has not been in existence for at least ten years.

The following are the standardized average annual total return quotations for
the Sub-Accounts for the period ended December 31, 1997.

In addition to the standardized total return, the Sub-Account may advertise a
non-standardized total return.  This figure will usually be calculated for one
year, five years, and ten years or other periods. Non-standardized total return
is measured in the same manner as the standardized total return described above,
except that the contingent deferred sales charge is not deducted.  Therefore,
non-standardized total return for a Sub-Account is higher than standardized
total return for a Sub-Account.

The following are the non-standardized annualized total return quotations for 
the Sub-Accounts for the period ended December 31, 1997.

                              PERFORMANCE COMPARISONS

YIELD AND TOTAL RETURN 

Each Sub-Account may from time to time include its total return in
advertisements or in information furnished to present or prospective
shareholders.  Each Sub-Account may from time to time include its yield and
total return in advertisements or information furnished to present or
prospective shareholders.  Each Sub-Account may from time to time include in
advertisements its total return (and yield in the case of certain Sub-Accounts)
the ranking of those performance figures relative to such figures for groups of
other annuities analyzed by Lipper Analytical Services and Morningstar, Inc. as
having the same investment objectives.

The total return and yield may also be used to compare the performance of the
Sub-Accounts against certain widely acknowledged outside standards or indices
for stock and bond market performance.  The Standard & Poor's Composite Index of
500 Stocks (the "S&P 500") is a market value-weighted and unmanaged index
showing the changes in the aggregate market value of 500 stocks relative to the
base period 1941-43.  The S&P 500 is composed almost entirely of common stocks
of companies listed on the New York Stock Exchange, although the common stocks
of a few companies listed on the American Stock Exchange or traded
over-the-counter are included.  The 500 companies represented include 400
industrial, 60 transportation and 40 financial services concerns.  The S&P 500
represents about 80% of the market value of all issues traded on the New York
Stock Exchange.

The NASDAQ-OTC Composite Price Index (The "NASDAQ Index") is a market
value-weighted and unmanaged index showing the changes in the aggregate market
value of approximately 3,500 stocks relative to the base measure of 100.00 on
February 5, 1971.  The NASDAQ Index is composed entirely of common stocks of
companies traded over-the-counter and often through the National Association of
Securities Dealers Automated Quotations ("NASDAQ") system.  Only those
over-the-counter stocks having only one market maker or traded on exchanges are
excluded.

The Morgan Stanley Capital International EAFE Index (the "EAFE Index") is an
unmanaged index, which includes over 1,000 companies representing the stock
markets of Europe,  Australia, New Zealand, and the Far East.  The


                                          6
<PAGE>

EAFE Index is weighted by market capitalization, and therefore, it has a heavy
representation in countries with large stock markets, such as Japan.

The Shearson Lehman Government Bond Index (the "SL Government Index") is a
measure of the market value of all public obligations of the U.S. Treasury; all
publicly issued debt of all agencies of the U.S. Government and all
quasi-federal corporations; and all corporate debt guaranteed by the U.S.
Government.  Mortgage-backed securities, flower bonds and foreign targeted
issues are not included in the SL Government Index.

The Shearson Lehman Government/Corporate Bond Index (the "SL
Government/Corporate Index") is a measure of the market value of approximately
5,300 bonds with a face value currently in excess of $1.3 trillion.  To be
included in the SL Government/Corporate Index, an issue must have amounts
outstanding in excess of $1 million, have at least one year to maturity and be
rated "Baa" or higher ("investment grade") by a nationally recognized rating
agency.

The Composite Index for Hartford Advisers Fund is comprised of the S&P 500
(55%), the Lehman Government/Corporate Bond Index (35%), both mentioned above,
and 90 Day U.S. Treasury Bills (10%).


                                           
                              VARIABLE ANNUITY PAYMENTS

ANNUITY UNIT VALUE

The value of an Annuity Unit is calculated at the same time that the value of an
Accumulation Unit is calculated and is based on the same values for Fund shares
and other assets and liabilities.  (See "Annuity Payments" in the Prospectus.) 
The Annuity Unit Value for each Sub-Account's first Valuation Period was set at
$10.  The Annuity Unit Value of each Sub-Account for any subsequent Valuation
Period is equal to (a) multiplied by (b) divided by (c) where:

     (a)  is the Net Investment Factor for the Valuation Period for which the
          Annuity Unit Value is being calculated;

     (b)  is the Annuity Unit Value for the preceding Valuation Period; and

     (c)  is a daily Assumed Investment Return factor (for the 3%, 5% or 6%
          Assumed Investment Return) adjusted for the number of days in the
          Valuation Period.

The Assumed Investment Return factor is equal to one plus the applicable
percentage.  Therefore, for 3%, it is 1.03, for 4% it is 1.04 and for 6% it is
1.06.  The annual factors can be translated into daily factor of 1.000080986,
1.00010746, and 1.000159654, respectively.

If a Contract Owner selects a 5% Assumed Investment Return rate and if the net
investment return of the Sub-Account for an Annuity Payment period is equal to
the pro-rated portion of the 5% Assumed Investment Return, the Variable Annuity
Payment attributable to that Sub-Account for that period will equal the Payment
for the prior period.  To the extent that such net investment return exceeds an
annualized rate of return of 5% for a Payment period, the Payment for that
period will be greater than the Payment for the prior period and to the extent
that such return for a period falls short of an annualized rate of 5%, the
Payment for that period will be less than the Payment for the prior period.

The following illustrations show, by use of hypothetical examples, the method of
determining the Annuity Unit

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To ITT Hartford Life and Annuity Insurance Company
Separate Account One and to the
Owners of Units of Interest Therein:
 
We have audited the accompanying statement of assets and liabilities of ITT
Hartford Life and Annuity Insurance Company Separate Account One (the Account)
as of December 31, 1997, and the related statement of operations for the year
then ended and statements of changes in net assets for each of the two years in
the period then ended. These financial statements are the responsibility of the
Account's management. Our responsibility is to express an opinion on these
financial statements based on our audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of ITT Hartford Life and Annuity
Insurance Company Separate Account One as of December 31, 1997, the results of
its operations for the year then ended and the changes in its net assets for
each of the two years in the period then ended in conformity with generally
accepted accounting principles.

                ITT HARTFORD LIFE AND ANNUITY INSURANCE COMPANY
                         NOTES TO FINANCIAL STATEMENTS
                               DECEMBER 31, 1997
 
 1. ORGANIZATION:
    Separate Account One (the Account) is a separate investment account within
ITT Hartford Life and Annuity Insurance Company (the Company) and is registered
with the Securities and Exchange Commission (SEC) as a unit investment trust
under the Investment Company Act of 1940, as amended. Both the Company and the
Account are subject to supervision and regulation by the Department of Insurance
of the State of Connecticut and the SEC. The Account invests deposits by
variable annuity contractholders of the Company in various mutual funds (the
Funds) as directed by the contractholders.
 
 2. SIGNIFICANT ACCOUNTING POLICIES:
    The following is a summary of significant accounting policies of the
Account, which are in accordance with generally accepted accounting principles
in the investment company industry:
 
    a) SECURITY TRANSACTIONS -- Security transactions are recorded on the trade
date (date the order to buy or sell is executed). Cost of investments sold is
determined on the basis of identified cost. Dividend and capital gains income
are accrued as of the ex-dividend date. Capital gains income represents
dividends from the Funds which are characterized as capital gains under tax
regulations.
 
    b) SECURITY VALUATION -- The investment in shares of the Funds are valued at
the closing net asset value per share as determined by the appropriate Fund as
of December 31, 1997.
 
    c) FEDERAL INCOME TAXES -- The operations of the Account form a part of, and
are taxed with, the total operations of the Company, which is taxed as an
insurance company under the Internal Revenue Code. Under current law, no federal
income taxes are payable with respect to the operations of the Account.
 
    d) USE OF ESTIMATES -- The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities as of the date of the financial statements and the reported amounts
of income and expenses during the period. Operating results in the future could
vary from the amounts derived from management's estimates.
 
 3. ADMINISTRATION OF THE ACCOUNT
   AND RELATED CHARGES:
 
    a) MORTALITY AND EXPENSE UNDERTAKINGS -- The Company, as issuer of variable
annuity contracts, provides the mortality and expense undertakings and, with
respect to the Account, receives a maximum annual fee of 1.25% of the Account's
average daily net assets.
 
    b) DEDUCTION OF ANNUAL MAINTENANCE FEE -- Annual maintenance fees are
deducted through termination of units of interest from applicable contract
owners' accounts, in accordance with the terms of the contracts.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Board of Directors of ITT Hartford Life
and Annuity Insurance Company:
 
We have audited the accompanying statutory balance sheets of ITT Hartford Life
and Annuity Insurance Company (a Connecticut Corporation and wholly owned
subsidiary of Hartford Life Insurance Company) (the Company) as of December 31,
1997 and 1996, and the related statutory statements of income, changes in
capital and surplus, and cash flows for each of the three years in the period
ended December 31, 1997. These financial statements are the responsibility of
the Company's management. Our responsibility is to express an opinion on these
statutory financial statements based on our audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
The Company presents its financial statements in conformity with statutory
accounting practices as described in Note 1 of notes to statutory financial
statements. When statutory financial statements are presented for purposes other
than for filing with a regulatory agency, generally accepted auditing standards
require that an auditors' report on them state whether they are presented in
conformity with generally accepted accounting principles. The accounting
practices used by the Company vary from generally accepted accounting principles
as explained and quantified in Note 1.
 
In our opinion, because the differences in accounting practices as described in
Note 1 are material, the statutory financial statements referred to above do not
present fairly, in accordance with generally accepted accounting principles, the
financial position of the Company as of December 31, 1997 and 1996, and the
results of its operations and its cash flows for each of three years in the
period ended December 31, 1997.
 
However, in our opinion, the statutory financial statements referred to above
present fairly, in all material respects, the financial position of the Company
as of December 31, 1997 and 1996, and the results of operations and its cash
flows for each of the three years in the period ended December 31, 1997 in
conformity with statutory accounting practices as described in Note 1.

                ITT HARTFORD LIFE AND ANNUITY INSURANCE COMPANY
                    NOTES TO STATUTORY FINANCIAL STATEMENTS
                               DECEMBER 31, 1997
                 (AMOUNTS IN THOUSANDS UNLESS OTHERWISE STATED)
 
 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
ORGANIZATION
 
    ITT Hartford Life and Annuity Insurance Company ("ILA" or "the Company"),
formerly known as ITT Life Insurance Corporation, is a wholly owned subsidiary
of Hartford Life Insurance Company ("HLIC"), which is an indirect subsidiary of
Hartford Life, Inc. ("HLI"), which is majority owned by The Hartford Financial
Services Group, Inc. ("The Hartford"), formerly a wholly owned subsidiary of ITT
Corporation ("ITT"). On February 10, 1997, HLI filed a registration statement,
as amended, with the Securities and Exchange Commission relating to the initial
public offering of HLI Class A Common Stock (the "Offering"). Pursuant to the
Offering on May 22, 1997, HLI sold to the public 26 million shares, representing
18.6% of the equity ownership of HLI. On December 19, 1995, ITT Corporation
distributed all the outstanding shares of The Hartford to ITT shareholders of
record in an action known herein as the "Distribution". As a result of the
Distribution, The Hartford became an independent, publicly traded company.
During 1996, ILA re-domesticated from the State of Wisconsin to the State of
Connecticut.
 
    ILA offers a complete line of ordinary and universal life insurance,
individual annuities and certain supplemental accident and health benefit
coverages.
 
BASIS OF PRESENTATION
 
    The accompanying ILA statutory financial statements were prepared in
conformity with statutory accounting practices prescribed or permitted by the
National Association of Insurance Commissioners ("NAIC") and the State of
Connecticut Department of Insurance.
 
    The preparation of financial statements in conformity with statutory
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reported period. Actual
results could differ from those estimates. The most significant estimates are
for determining the liability for aggregate reserves for future benefits and the
liability for premium and other deposit funds. Although some variability is
inherent in these estimates, management believes the amounts provided are
adequate.
 
    Statutory accounting practices and generally accepted accounting principles
("GAAP") differ in certain significant respects. These differences principally
involve:
 
(1) treatment of policy acquisition costs (commissions, underwriting and selling
    expenses, premium taxes, etc.) which are charged to expense when incurred
    for statutory purposes rather than on a pro-rata basis over the expected
    life of the policy;
 
(2) recognition of premium revenues, which for statutory purposes are generally
    recorded as collected or when due during the premium paying period of the
    contract and which for GAAP purposes, for universal life policies and
    investment products, generally, are only recorded for policy charges for the
    cost of insurance, policy administration and surrender charges assessed to
    policy account balances. Also, for GAAP purposes, premiums for traditional
    life insurance policies are recognized as revenues when they are due from
    policyholders and the retrospective deposit method is used in accounting for
    universal life and other types of contracts where the payment pattern is
    irregular or surrender charges are a significant source of profit. The
    prospective deposit method is used for GAAP purposes where investment
    margins are the primary source of profit;
 
(3) development of liabilities for future policy benefits, which for statutory
    purposes predominantly use interest rate and mortality assumptions
    prescribed by the NAIC which may vary considerably from interest and
    mortality assumptions used for GAAP financial reporting;
 
(4) providing for income taxes based on current taxable income (tax return) only
    for statutory purposes, rather than establishing additional assets or
    liabilities for deferred Federal income taxes to recognize the tax effect
    related to reporting revenues and expenses in different periods for
    financial reporting and tax return purposes;
 
(5) excluding certain GAAP assets designated as non-admitted assets (e.g., past
    due agents' balances and furniture and equipment) from the balance sheet for
    statutory purposes by directly charging surplus;
 
(6) establishing accruals for post-retirement and post-employment health care
    benefits on an option basis, using a twenty year phase-in approach, whereas
    GAAP liabilities are recorded upon adoption of the applicable standard;
<PAGE>
- --------------------------------------------------------------------------------
 
(7) establishing a formula reserve for realized and unrealized losses due to
    default and equity risk associated with certain invested assets (Asset
    Valuation Reserve); as well as the deferral and amortization of realized
    gains and losses, motivated by changes in interest rates during the period
    the asset is held, into income over the remaining life to maturity of the
    asset sold (Interest Maintenance Reserve); whereas on a GAAP basis, no such
    formula reserve is required and realized gains and losses are recognized in
    the period the asset is sold;
 
(8) the reporting of reserves and benefits net of reinsurance ceded, where risk
    transfer has taken place; whereas on a GAAP basis, reserves are reported
    gross of reinsurance with reserve credits presented as recoverable assets;
 
(9) the reporting of fixed maturities at amortized cost, whereas GAAP requires
    that fixed maturities be classified as "held-to-maturity",
    "available-for-sale" or "trading", based on the Company's intentions with
    respect to the ultimate disposition of the security and its ability to
    affect those intentions. The Company's bonds were classified on a GAAP basis
    as "available-for-sale" and accordingly, those investments and common stocks
    were reflected at fair value with the corresponding impact included as a
    component of Stockholder's Equity designated as "Net unrealized capital
    gains (losses) on securities net of tax". For statutory reporting purposes,
    Change in Net Unrealized Capital Gains (Losses) on Common Stocks and Other
    Invested Assets includes the change in unrealized gains (losses) on common
    stock reported at fair value; and
 
(10) separate account liabilities are valued on the Commissioner's Annuity
    Reserve Valuation Method ("CARVM"), with the surplus generated recorded as a
    liability to the general account (and a contra liability on the balance
    sheet of the general account), whereas GAAP liabilities are valued at
    account value.
 
    As of and for the years ended December 31, 1997, 1996 and 1995, the
significant differences between statutory and GAAP basis net income and capital
and surplus for the Company are summarized as follows:

</TABLE>
 
AGGREGATE RESERVES FOR FUTURE BENEFITS AND LIABILITY FOR PREMIUM AND OTHER
DEPOSIT FUNDS
 
    Aggregate reserves for payment of future life, health and annuity benefits
were computed in accordance with actuarial standards. Reserves for life
insurance policies are generally based on the 1958 and 1980 Commissioner's
Standard Ordinary Mortality Tables and various valuation rates ranging from 2.5%
to 6%. Accumulation and on-benefit annuity reserves are based principally on
individual annuity tables at various rates ranging from 2.5% to 8.75% and using
CARVM. Accident and health reserves are established using a two year preliminary
term method and morbidity tables based on Company experience.
 
    ILA has established separate accounts to segregate the assets and
liabilities of certain annuity contracts that must be segregated from the
Company's general assets under the terms of the contracts. The assets consist
primarily of marketable securities reported at market value. Premiums, benefits
and expenses of these contracts are reported in the Statutory Statements of
Income.
 
INVESTMENTS
 
    Investments in bonds are carried at amortized cost. Bonds which are deemed
ineligible to be held at amortized cost by the NAIC Securities Valuation Office
("SVO") are carried at the appropriate SVO published value. When a permanent
reduction in the value of publicly traded securities occurs, the decrease is
reported as a realized loss and the carrying value is adjusted accordingly.
Common stocks are carried at fair value with the current year change in the
difference from cost reflected in surplus. Other invested assets are generally
recorded at fair value.
 
    The Asset Valuation Reserve ("AVR") is designed to provide a standardized
reserving process for realized and unrealized losses due to default and equity
risks associated with invested assets. The reserve increased by $6,228 in 1997,
decreased by $568 in 1996 and increased by $5,588 in 1995. Additionally, the
Interest Maintenance Reserve
<PAGE>
- --------------------------------------------------------------------------------
 
("IMR") captures net realized capital gains and losses, net of applicable income
taxes, resulting from changes in interest rates and amortizes these gains or
losses into income over the remaining life of the mortgage loan or bond sold.
Realized capital gains and losses, net of taxes not included in IMR are reported
in the Statutory Statements of Income. Realized investment gains and losses are
determined on a specific identification basis. The amount of net capital losses
reclassified from the IMR was $719 in 1997 and the amount of net capital gains
reclassified was $1,413 and $39 in 1996 and 1995, respectively. The amount of
income amortized was $85, $392 and $256 in 1997, 1996 and 1995, respectively.
 
OTHER LIABILITIES
    The amount reflected in other liabilities includes a receivable from the
separate accounts of $923 million and $640 million as of December 31, 1997 and
1996, respectively. The balances are classified in accordance with NAIC
accounting practices.
 
MORTGAGE LOANS
    Mortgage loans, carried at cost, which approximates fair value, include
investments in assets backed by mortgage loan pools.

 3. RELATED PARTY TRANSACTIONS:
 
    Transactions between the Company and its affiliates within The Hartford
relate principally to tax settlements, reinsurance, service fees, capital
contributions and payments of dividends. The Company has also invested in bonds
of its subsidiaries, Hartford Financial Services Corporation and HL Investment
Advisors, Inc., and common stock of its subsidiary, ITT Hartford Life, LTD.
 
    On June 30, 1995, the assets of Lyndon Insurance Company were contributed to
ILA. As a result, ILA received approximately $365 million in bonds and
short-term investments, common stocks and cash, $28 million in policy reserves,
$187 million of current tax liability, $26 million in IMR, $8 million in AVR
(offset by an aggregate write-in to surplus), and $4 million of other
liabilities. The assets in excess of liabilities of $112 million were recorded
as an increase to paid-in surplus.
 
    For additional information, see Note 5.
 
 4. FEDERAL INCOME TAXES:
 
    The Company and The Hartford have entered into a tax sharing agreement under
which each member in the consolidated U.S. Federal income tax return will make
payments between them such that, with respect to any period, the amount of taxes
to be paid by the Company, subject to certain adjustments, generally will be
determined as though the Company were to file separate Federal, state and local
income tax returns.
 
    As long as The Hartford continues to beneficially own, directly or
indirectly, at least 80% of the combined voting power and 80% of the value of
the outstanding capital stock of HLI, the Company will be included for Federal
income tax purposes in the consolidated group of which The Hartford is the
common parent. It is the current intention of The Hartford and its subsidiaries
to continue to file a single consolidated Federal income tax return. The Company
will continue to remit (receive from) The Hartford a current income tax
provision (benefit) computed in accordance with such tax sharing agreement.
Federal income taxes (received) paid by the Company were $(14,499), $29,792 and
$215,921 in 1997, 1996 and 1995, respectively. The effective tax rate was (26)%,
22% and 25% in 1997, 1996 and 1995, respectively. The following schedule
provides a reconciliation of the tax provision at the U.S. Federal Statutory
rate to Federal income tax (benefit) expense (in millions).

 5. CAPITAL AND SURPLUS AND SHAREHOLDER
   DIVIDEND RESTRICTIONS:
 
    The maximum amount of dividends which can be paid, without prior approval,
by State of Connecticut insurance companies to shareholders is subject to
restrictions relating to statutory surplus. Dividends are paid as determined by
the Board of Directors and are not cumulative. No dividends were paid in 1997 or
1996. ILA paid dividends of $10 million to its parent, HLIC, in 1995. As a
result of the Distribution by ITT, the assets of ITT Lyndon Insurance Company
(Lyndon) were contributed to ILA in June 1995. Substantially all the business
was removed from Lyndon prior to the contribution. The amount of assets which
<PAGE>
- --------------------------------------------------------------------------------
 
exceeded liabilities at the contribution date ($112 million) was included in
paid-in surplus.
 
 6. PENSION PLANS AND OTHER POST-RETIREMENT AND POST-EMPLOYMENT BENEFITS:
 
    The Company's employees are included in The Hartford's non-contributory
defined benefit pension plans. These plans provide pension benefits that are
based on years of service and the employee's compensation during the last ten
years of employment. The Company's funding policy is to contribute annually an
amount between the minimum funding requirements set forth in the Employee
Retirement Income Security Act of 1974 and the maximum amount that can be
deducted for Federal income tax purposes. Generally, pension costs are funded
through the purchase of HLIC's group pension contracts. Pension expense was
$265, $358, and $1,034 in 1997, 1996 and 1995, respectively. Liabilities for the
plan are held by The Hartford.
 
    The Company also participates in The Hartford's Investment and Savings Plan,
which includes a deferred compensation option under IRC section 401(k) and an
ESOP allocation under IRC section 404(k). The liabilities for these plans are
included in the financial statements of The Hartford. The cost to ILA was not
material in 1997, 1996 and 1995.
 
    The Company's employees are included in The Hartford's contributory defined
health care and life insurance benefit plans. These plans provide health care
and life insurance benefits for retired employees. Substantially all employees
may become eligible for those benefits if they reach normal or early retirement
age while still working for the Company. The Company has prefunded a portion of
the health care and life insurance obligations through trust funds where such
prefunding can be accomplished on a tax effective basis. Amounts allocated by
The Hartford for post-retirement health care and life insurance benefits expense
(not including provisions for accrual of post-retirement benefit obligations)
are immaterial. The assumed rate of future increases in the per capita cost of
health care (the health care trend rate) was 8.5% for 1997, decreasing ratably
to 6% in the year 2001. Increasing the health care trend rates by one percent
per year would have an immaterial impact on the accumulated post-retirement
benefit obligation and the annual expense. The cost to ILA was not material in
1997, 1996 and 1995.
 
    Post-employment benefits are primarily comprised of obligations to provide
medical and life insurance to employees on long-term disability. Post-employment
benefit expense was not material in 1997, 1996 and 1995.
 
 7. REINSURANCE:
 
    The Company cedes insurance to non-affiliated insurers in order to limit its
maximum loss. Such transfer does not relieve ILA of its primary liability. ILA
also assumes insurance from other insurers.
 
    Life insurance net retained premiums were comprised of the following:

</TABLE>
 
    The Company cedes to RGA Reinsurance Company, on a modified coinsurance
basis, 80% of the variable annuity business written since 1994.
 
 8. SEPARATE ACCOUNTS:
 
    The Company maintains separate account assets and liabilities totaling $23.2
billion and $14.6 billion at December 31, 1997 and 1996, respectively. Separate
account assets are reported at fair value and separate account liabilities are
determined in accordance with CARVM, which approximates the market value less
applicable surrender charges. Separate account assets are segregated from other
investments, the policyholder assumes the investment risk, and the investment
income and gains and losses accrue directly to the policyholder. Separate
account management fees, net of minimum guarantees, were $252 million, $144
million and $72 million in 1997, 1996 and 1995, respectively, and are recorded
as a component of other revenues on the Statutory Statements of Income.
 
 9. COMMITMENTS AND CONTINGENCIES:
 
    As of December 31, 1997 and 1996, the Company had no material contingent
liabilities, nor had the Company committed any surplus funds for any contingent
liabilities or arrangements. The Company is involved in various legal actions
which have arisen in the normal course of its business. In the opinion of
management, the ultimate liability with respect to such lawsuits as well as
other contingencies is not considered to be material in relation to the results
of operations and financial position of the Company.
 
    Under insurance guaranty laws in most states, insurers doing business
therein can be assessed up to prescribed limits for policyholder losses incurred
by insolvent companies. The amount of any future assessments on ILA under these
laws cannot be reasonably estimated. Most of the laws do provide, however, that
an assessment may be excused or deferred if it would threaten an insurer's own
financial strength. Additionally, guaranty fund assessments are used to reduce
state premium taxes paid by the Company in certain states. ILA paid guaranty
fund assessments of $1,544, $1,262 and $1,684 in 1997, 1996 and 1995,
respectively. ILA incurred guaranteed fund expense of $548 in 1997 and 1996 and
$0 in 1995.

Item 26.  Persons Controlled By or Under Common Control with the Depositor or
Registrant

          Filed herewith as Exhibit 16.
          
Item 27.  Number of Contract Owners

          As of February 28, 1998, there were 207,515 Contract Owners.

Item 28.  Indemnification


                                         -3-
<PAGE>

Under Section 33-772 of the Connecticut General Statutes, unless limited by its
certificate of incorporation, the Registrant must indemnify a director who was
wholly successful, on the merits or otherwise, in the defense of any proceeding
to which he was a party because he is or was a director of the corporation
against reasonable expenses incurred by him in connection with the proceeding.

The Registrant may indemnify an individual made a party to a proceeding because
he is or was a director against liability incurred in the proceeding if he acted
in good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the Registrant, and, with respect to any criminal
proceeding, had no reason to believe his conduct was unlawful. Conn. Gen. Stat.
Section 33-771(a). Additionally, pursuant to Conn. Gen. Stat. Section 33-776,
the Registrant may indemnify officers and employees or agents for liability
incurred and for any expenses to which they becomes subject by reason of being
or having been an employees or officers of the Registrant.  Connecticut law does
not prescribe standards for the indemnification of officers, employees and
agents and expressly states that their indemnification may be broader than the
right of indemnification granted to directors. 

The foregoing statements are specifically made subject to the detailed
provisions of Section 33-770 et seq.
          
Notwithstanding the fact that Connecticut law obligates the Registrant to
indemnify only a director that was successful on the merits in a suit, under
Article VIII, Section 2 of the Registrant's bylaws, the Registrant must
indemnify both directors and officers of the Registrant who are parties or
threatened to be parties to a legal proceeding by reason of his being or having
been a director or officer of the Registrant for any expenses if he acted in
good faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the company, and with respect to criminal proceedings, had no
reason to believe his conduct was unlawful.  Unless otherwise mandated by a
court, no indemnification shall be made if such officer or director is adjudged
to be liable for negligence or misconduct in the performance of his duty to the
Registrant.

Additionally, the directors and officers of Hartford and Hartford Securities
Distribution Company, Inc. ("HSD") are covered under a directors and officers
liability insurance policy issued to The Hartford Financial Services Group, Inc.
and its subsidiaries.  Such policy will reimburse the Registrant for any
payments that it shall make to directors and officers pursuant to law and will,
subject to certain exclusions contained in the policy, further pay any other
costs, charges and expenses and settlements and judgments arising from any
proceeding involving any director or officer of the Registrant in his past or
present capacity as such, and for which he may be liable, except as to any
liabilities arising from acts that are deemed to be uninsurable.
          
Insofar as indemnification for liabilities arising under the Securities Act of
1933 (the "Act") may be permitted to directors, officers and controlling persons
of the Registrant pursuant to the foregoing provisions, the Registrant has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable.  In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses 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 or controlling person in 


                                         -4-
<PAGE>

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
be governed by the final adjudication of such issue.

RE:  Hartford Life and Annuity Insurance Company Separate Account One
     Immediate Variable Annuity
     File No. 333-19607

Dear Sir/Madam:

I have acted as General Counsel to Hartford Life and Annuity Insurance Company
(the "Company"), a Connecticut insurance company, and Hartford Life and Annuity
Insurance Company Separate Account One (the "Account") in Connecticut with the
registration of an indefinite amount of securities in the form of single premium
variable annuity insurance contracts (the "Contracts") with the Securities and
Exchange Commission under the Securities Act of 1933, as amended.  I have
examined such documents (including the Form N-4 Registration Statement) and
reviewed such questions of law as I considered necessary and appropriate, and on
the basis of such examination and review, it is my opinion that:

1.   The Company is a corporation duly organized and validly existing as a stock
     life insurance company under the laws of the State of Connecticut and is
     duly authorized to by the Insurance Department of the State of Connecticut
     to issue the Contacts.

2.   The Account is a duly authorized and existing separate account established
     pursuant to the provisions of Section 38a-433 of the Connecticut Statutes.

3.   To the extent so provided under the Contracts, that portion of the assets
     of the Account equal to the reserves and other contract liabilities with
     respect to the Account will not be chargeable with liabilities arising out
     of any other business that the Company may conduct.

4.   The Contracts, when issued as contemplated by the Form N-4 registration
     statement, will constitute legal, validly issued and binding obligations of
     the Company.
