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

(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

less than the AIR, the payment amount will be lower.

    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 prospectuses of the Funds. For

                             PURCHASING A CONTRACT
 
    A prospective Contract Owner may purchase a Contract by completing and

    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 an Allocating Premium Payments.")
                         RIGHT TO EXAMINE THE CONTRACT
 
    Owners may cancel the Contract during the Right to Examine period and
receive a refund equal to the Contract Value. The Right to Examine Period is a
10-day period of time beginning when the Contract is received by a Contract
Owner. Some states require a longer Right to Examine Period and Return of
Premium. (See "Right to Examine the Contract.")
                                   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.") Similar transfers may
be made after the Income Start Date, subject to certain restrictions. (See
"Variable Annuity Payments.")
                            ANNUITY PAYMENT OPTIONS
 
    The following Annuity Payment Options are available under the contract; Life
Annuity; Life Annuity with Premium Payment Refund; Life Annuity with Payments
Guaranteed For a Specified Number of Years; Joint and Last Survivor Life Annuity

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 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.") Certain Annuity Payment
Options do not provide a Death Benefit.
                                   SURRENDERS

may surrender the Contract and receive its Contract Value. On or after the
Income Start Date Under a Guaranteed Payments for a Specified number of Years
Annuity Option, a Contract Owner also may surrender the contract for the
commuted value. (See "Surrenders.") Surrenders may have adverse federal income
tax consequences including the possibility of being subject to a penalty tax.
(See "Federal Tax Considerations.")
                                CHARGES AND FEES
 
    The following charges and fees are assessed under the Contracts:
 
    CONTINGENT DEFERRED SALES CHARGE. ITT Hartford deducts a contingent deferred
sales charge if the Contract is surrendered after the Income Start Date under
GUARANTEED PAYMENTS FOR A SPECIFIED NUMBER OF YEARS ANNUITY 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.

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.")
 
    PREMIUM TAX CHARGE. Generally, taxes on premium payments, if any, 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 range from 0% to 4.0% of premium payments. (See "Premium Tax
Charge.")
 
    EXPENSES OF THE FUNDS. The investment experience of each Sub-Account

                ITT HARTFORD, THE SEPARATE ACCOUNT AND THE FUNDS
                         ITT HARTFORD LIFE AND ANNUITY
                               INSURANCE COMPANY
 
    ITT Hartford Life and Annuity Insurance Company ("ITT Hartford"), formerly
ITT Life Insurance Corporation was originally incorporated under the laws of
Wisconsin on January 9, 1956. ITT Hartford was redomiciled to Connecticut on May
1, 1996. It is a stock life insurance company engaged on the business of writing
both individual and group life insurance and annuities in all states including
the District of Columbia, except New York. The offices of ITT Hartford are
located in Minneapolis, Minnesota; however, its mailing address is P.O. Box 5085
Hartford, Connecticut 06102-5085.
 
    ITT Hartford is a wholly owned subsidiary of Hartford Life Insurance
Company. ITT Hartford is ultimately 100% owned by Hartford Fire Insurance
Company, one of the largest multiple lines insurance carriers in the United
States. On December 20, 1995, Hartford Fire Insurance Company became an
independent, publicly traded corporation.
                       ITT HARTFORD SEPARATE ACCOUNT ONE
 
    Separate Account One is a separate investment account of ITT Hartford
established under Connecticut law on May 20, 1991. ITT Hartford owns the assets
of the Separate Account. These assets are held separate from the ITT Hartford's
general account and its other separate accounts. That portion of the Separate

the Separate Account is not chargeable with liabilities arising out of any other
business ITT Hartford may conduct.
 
    The Separate Account is registered with the SEC 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 SEC of the management of the Separate
Account or of ITT Hartford. The Separate Account is also governed by the laws of
Connecticut, ITT Hartford's state of domicile, and may also be governed by laws
of other states in which ITT Hartford does business.
 
    CHANGES TO THE SEPARATE ACCOUNT. Where permitted by applicable law, ITT
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 the Company 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 the Company determines that investment
    in a Fund is no longer appropriate in light of the purposes of the Separate
    Account;
 
7.  re-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 SEC 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 investment company managed by Hartford
Investment Management Company ("HIMCO"), a registered investment adviser. HIMCO
has retained Wellington Management Company to act as investment sub-adviser to
the Funds indicated by an asterisk (*). The Funds, as well as a brief
description of their investment objectives, are provided below:

    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' PROSPECTUSES 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.
 
    ITT Hartford cannot guarantee that each Fund will always be available under
the Contracts, but in the unlikely event that a Fund is not available, ITT
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 ITT 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, ITT 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 each Fund's prospectus.
                          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
Home Office along with the Contract Owner's application or an order request. The
minimum
 
(1)"STANDARD & POOR'S-REGISTERED TRADEMARK-", "S&P-REGISTERED TRADEMARK-", "S&P
   500-REGISTERED TRADEMARK-", "STANDARD & POOR'S 500", AND "500" ARE TRADEMARKS
   OF THE MCGRAW-HILL COMPANIES, INC. AND HAVE BEEN LICENSED FOR USE BY ITT
   HARTFORD LIFE AND ANNUITY INSURANCE COMPANY. THE INDEX FUND IS NOT SPONSORED,
   ENDORSED, SOLD OR PROMOTED BY STANDARD & POOR'S ("S&P") AND S&P MAKES NO

Premium Payment is $25,000 unless ITT Hartford specifically consents to a lower
Payment. No additional Premium Payments may be made under the Contracts. Unless
ITT Hartford gives its prior approval, it will not accept a Premium Payment in
excess of $1,000,000. ITT 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 Right to Examine Period,
which is the 10-day period beginning on the day the 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 Home Office of ITT Hartford.
 
    ITT 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 the company's receipt of the request for cancellation. ITT
Hartford will refund the premium paid 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, ITT 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 ITT 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. The investment in the Separate Account is allocated to one or more
Sub-Accounts as per the Contract Owner specifications. Each Sub-Account is
invested exclusively in the assets of one underlying Fund. The Separate Account
has 11 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 ITT Hartford. Contract Owners may allocate
the Premium Payment among any or all available Sub-Accounts subject to minimum
amounts then in effect. 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 value of the Accumulation Unit 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.
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
<PAGE>

- --------------------------------------------------------------------------------
 
by dividing (1) by (2) and subtracting (3) from the result, where:
 
(1) is the result of:
 
    a.  the Net Asset Value Per Share 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
 
(2) is the Net Asset Value Per Share 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, ITT 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 (800) 862-6668 or by
the agent of record by calling (800) 862-7155. Telephone transfers may not be
permitted by some states for their residents who purchase variable annuities.
 
    The policy of ITT 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. ITT Hartford will employ reasonable
procedures to confirm that instructions communicated by telephone are genuine;
otherwise, ITT Hartford may be liable for any losses due to unauthorized or
fraudulent instructions. The procedures ITT 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 Annuity
Payments commence provided that the minimum allocation to any Sub-Account may
not be less than the minimum then in effect. All percentage (%) allocations must
be in whole numbers (1%).
 
    It is the responsibility of the Contract Owner to verify the accuracy of all
confirmations of transfers and to promptly advise ITT Hartford of any
inaccuracies within one business day of receipt of the confirmation. ITT
Hartford will send the Contract Owner a confirmation of the transfer within five
(5) 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 ITT 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 not 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 ITT 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 ITT 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 ITT Hartford.
                                   SURRENDERS
 
ON OR BEFORE THE ANNUITY CALCULATION DATE.
 
    A Contract Owner may surrender the 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. ITT Hartford does not guarantee any minimum
Surrender Value. The Surrender Value will be determined as of the date ITT
Hartford receives the Written Notice for surrender at the Home Office.
 
AFTER ANNUITY CALCULATION DATE.
 
    A Contract Owner may surrender the Contract on or after the Income Start
Date only if the Annuity Payment Option GUARANTEED PAYMENTS FOR A SPECIFIED
NUMBER OF YEARS Annuity Payment Option is in effect. Upon such a surrender ITT
Hartford pays the Contract Owner the Commuted Value less any applicable
Contingent Deferred Sales Charges. The surrender charge is computed as of the
date ITT Hartford receives the Written Notice for surrender at the Home Office.
 
    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
the imposition of a penalty tax of 10% of the taxable portion of the Surrender
Value. See "FEDERAL TAX CONSIDERATIONS" for more details.

- --------------------------------------------------------------------------------
 
                         DEATH BEFORE INCOME START DATE
 
    If the Contract Owner or the Annuitant dies before the Income Start Date,
ITT 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 ITT 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 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, ITT 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 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.
 
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 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 ITT Hartford receives
written notification of Due Proof of Death. Any annuity payments made on or
after the date of death, but before receipt of written notification of Due Proof
of Death will be recovered by ITT 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 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 Money Market
Fund.
 
    Upon receipt of complete instructions, ITT Hartford will proceed as follows:
If the instructions are to resume payments, ITT Hartford will make any payments
that went unpaid since the date ITT Hartford received notification of Due Proof
of Death. ITT Hartford will then reallocate the remaining balance in the Money
Market Fund according to the instructions and resume payments. If the
instructions are to pay the Death Benefit in one sum, ITT Hartford will pay the
Death Benefit.
                           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 5 years
 
2)  under an Annuity 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 Owner. If the spouse
<PAGE>
ITT HARTFORD LIFE AND ANNUITY INSURANCE COMPANY
 
- --------------------------------------------------------------------------------
 
    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.
 
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 this contract.
                          PAYMENTS UNDER THE CONTRACT
 
    ITT 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, ITT 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 SEC; or
 
2.  when the SEC by order permits a postponement for the protection of Contract
    Owners; or
 
3.  when the SEC 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, ITT 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 payment, and the
amount of each Payment. The Contract Owner must select the Annuity 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.  ITT Hartford makes Annuity Payments to the Payee for as long
as the Annuitant lives. UNDER THIS OPTION, A PAYEE WOULD RECEIVE ONLY ONE
PAYMENT IF THE ANNUITANT DIES AFTER THE FIRST PAYMENT, TWO PAYMENTS IF THE
ANNUITANT DIES AFTER THE SECOND PAYMENT, ETC.
 
    LIFE ANNUITY WITH CASH REFUND.  ITT 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.
 
    LIFE ANNUITY WITH PAYMENTS GUARANTEED FOR A SPECIFIED NUMBER OF YEARS.  ITT
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 5 years and maximum of 100 minus the annuitants
age). 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 present value of
the remaining payments in 1 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.  ITT Hartford makes Annuity Payments
to the Payee while both Annuitants are living. After the death of either
Annuitant, Payments continue to the Payee for as long as the other Annuitant
lives. UNDER THIS OPTION, A PAYEE WOULD RECEIVE ONLY ONE PAYMENT IF BOTH
ANNUITANTS DIE AFTER THE FIRST PAYMENT, ETC. At the time of purchase the
Contract Owner must elect to have 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.  ITT Hartford makes Annuity Payments to the Payee
while both Annuitants are living. After the death of either Annuitant, 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 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 5 years and maximum of 100
minus the younger annuitants 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
<PAGE>

- --------------------------------------------------------------------------------
 
of the period or receiving the present value of the remaining payments in 1 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.  ITT Hartford makes
Annuity Payments to the Payee for the number of years (a minimum of 5 years and
maximum of 100 minus the annuitants 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
the 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 present value of the remaining payments in 1 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, ITT 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 Owner selects the Income Start Date in the application or order request.
The Annuity Calculation Date will be no more than 5 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 a Payment frequency,
Annuity Payments will be made monthly.
                           VARIABLE ANNUITY PAYMENTS
 
    THE FIRST VARIABLE ANNUITY PAYMENT.  Variable Annuity Payments are periodic
payments from the Company 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
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 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.
 
    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 preceding what would have been the Income Payment Date.
<PAGE>
ITT HARTFORD LIFE AND ANNUITY INSURANCE COMPANY
 
- --------------------------------------------------------------------------------
 
    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.
 
    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%.
 
    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. The Contract permits Contract Owners to select one of three
Assumed Investment Returns: 3%, 5% or 6%. 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 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
    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 3%, the Payment for that period will be less than the
    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 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.
 
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 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
    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 6%, the Payment for that period will be less than the
    Payment for the prior period.
 
    EXCHANGE ("TRANSFER") OF ANNUITY UNITS.  After the Annuity Calculation Date,
the 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 ITT
Hartford Life receives written notice requesting transfer. For guidelines refer
to "Sub-Account Value Transfers" on page   .
                           CONTRACT FEES AND CHARGES
                        CONTINGENT DEFERRED SALES CHARGE
 
    No sales charge is deducted from the Premium Payment at the time that the
Payment is made. However, a Contingent Deferred Sales Charge is deducted upon
surrender of the Contract and when a Contract Owner elects to receive the
Commuted Value under the Annuity Payment Option PAYMENTS GUARANTEED FOR A
SPECIFIED NUMBER OF YEARS.
 
    In the event that surrender charges from the Contracts are not sufficient to
cover the expenses of selling the Contracts, ITT 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 ITT
Hartford. ITT Hartford

does not expect that the surrender charges deducted will cover the costs of
distributing the Contracts. Any shortfall will be made up from ITT Hartford's
general assets, which may include amounts derived from the mortality and expense
risk charge.
 
    The surrender charge is equal to a percentage of the Commuted Value (not to
exceed Premium Payment) and is deducted from those values prior to their being
paid.

                               PREMIUM TAX CHARGE
 
    Certain states and municipalities impose a tax on ITT Hartford in connection
with the receipt of annuity premiums or contract value. This tax can range from
0% to 4% of either the premium or the contract value and is generally based on
the Owner's state of residence. Taxes are generally incurred by ITT Hartford as
of the Annuity Calculation Date. ITT Hartford deducts the charge for taxes from
the Contract Value on the Annuity Calculation Date. Some jurisdictions impose a
tax on annuity premiums at the time the premium is received. In those
jurisdictions, ITT Hartford's current practice is to pay the tax on annuity
premium 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
 
    ITT Hartford deducts a daily charge from the assets of the Separate Account
to compensate ITT Hartford for mortality and expense risks that ITT 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.
If the mortality and expense risk charge is insufficient to cover the actual
cost of the mortality and expense risks undertaken by ITT Hartford, ITT Hartford
will bear the shortfall. Conversely, if the charge proves more than sufficient,
the excess will be retained by ITT Hartford and will be available for any proper
purpose including, among other things, payment of expenses incurred in selling
the Contracts.
 
    The mortality risk that ITT 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 ITT 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. ITT Hartford also assumes a
mortality risk because the Contracts guarantee a "death benefit" if the 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" for more details.
 
    Selection of an Annuitant or Payee who is not the Contract Owner may have
adverse tax consequences. See "FEDERAL TAX CONSIDERATIONS" for more details.

                   CHANGING THE CONTRACT OWNER OR BENEFICIARY
 
    At any time, after the Cancellation Period, an Owner may transfer ownership
of the Contract subject to ITT Hartford's published rules 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 ITT
Hartford before a new Beneficiary is designated.
 
    These changes take effect as of the day the Written Notice was signed and
dated. ITT 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."
                           MISSTATEMENT OF AGE OR SEX
 
    If an age or sex of the Annuitant given to ITT Hartford (in the application
or otherwise) is misstated, ITT 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 ITT 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 ITT 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, ITT Hartford may modify the Contract to:
 
1.  conform the Contract or the operations of ITT Hartford or of the Separate
    Account to the requirements of any law to which the Contract, ITT 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, ITT 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
ITT Hartford. Any modification or waiver must be in writing. No agent may bind
ITT Hartford by making any promise not contained in the Contract.
                           REPORTS TO CONTRACT OWNERS
 
    ITT 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 SEC or the insurance supervisory official of the jurisdiction in
which the Contract is issued.
 
    ITT 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 ITT Hartford and ITT Hartford does not pay dividends on the Contract.
 
    PROOF OF AGE AND SURVIVAL.  ITT Hartford reserves the right to require proof
of the Annuitant's age and gender prior to the Annuity Calculation Date. In
addition, ITT Hartford reserves the right to require proof that the Annuitant is
living before any Income Payment Date.
 
    CONTRACT APPLICATION OR ORDER REQUEST.  ITT Hartford issues the Contract in
consideration of the Contract Owner's application or order request and payment
of the Premium. The entire Contract is made up of the Contract and any attached
endorsements or riders. In the absence of fraud, ITT Hartford considers
statements made in the application or order request to be representations and
not warranties. ITT 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.
ITT Hartford will not contest the Contract.
                               VOTING PRIVILEGES
 
    In accordance with current interpretations of applicable law, ITT 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.
<PAGE>

- --------------------------------------------------------------------------------
 
    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 Per Share 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 by the Net Asset Value Per Share of the Fund in which that
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 ITT 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 ITT Hartford's understanding of current
federal income tax laws as they are currently interpreted.
                            TAXATION OF ITT HARTFORD
                            AND THE SEPARATE ACCOUNT
 
    The Separate Account is taxed as part of ITT Hartford which is taxed as a
life insurance company under Subchapter L of Chapter 1 of the Code. Accordingly,
the Separate Account is not separately taxed as a "regulated investment company"
under subchapter M. 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, among others,
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.
<PAGE>
ITT HARTFORD LIFE AND ANNUITY INSURANCE COMPANY
 
- --------------------------------------------------------------------------------
 
    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 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) ITT
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.
 
    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 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 that are issued by ITT Hartford (or its affiliates) to the same owner
during any 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
<PAGE>
                                 ITT HARTFORD LIFE AND ANNUITY INSURANCE COMPANY
 
- --------------------------------------------------------------------------------
 
non-qualified annuities that did not have "substantial life contingencies" by
taxing income as it is credited to the annuity contract. Although as of the date
of this prospectus Congress is not considering any legislation regarding
taxation of annuity contracts, 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 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 wishing 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 the Company does not have direct control over the Funds in
which the Separate Account invests, ITT 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 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 Owner of a Contract 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 an Owner being treated as the owner of the assets of the Separate
Account. In addition, ITT 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. ITT Hartford therefore reserves the right to modify
the Contract as necessary to attempt to prevent the 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 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 Owner's death; and (b) if any 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 Owner's
<PAGE>

- --------------------------------------------------------------------------------
 
death. These requirements will be considered satisfied as to any portion of the
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
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 Owner, the
Contract may be continued with 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, however.
 
    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. ITT 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 Individual Retirement Annuities
("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. 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 ITT Hartford is not bound by the terms and conditions of such plans to the
extent such terms conflict with the Contract, unless ITT 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.
ITT 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
individual retirement annuity ('IRA') purchased through a tax-deferred rollover
contribution from another IRA, a retirement plan qualified under section 401 or
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 received (or
deemed received) 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, or
 
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.
 
    In addition, effective for distributions from an IRA made after December 31,
1996, there is no such penalty tax on distributions:
 
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.
 
    CODE SECTION 457 DEFERRED COMPENSATION PLANS.  The Contract 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 unless
made after the participant attains the age specified in the plan,

separates from service, dies, or suffers an unforeseeable financial emergency.
Distributions under 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 ITT Hartford, ITT 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
ITT 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 the Company's understanding of current law
and the law may change. Federal estate and state and local 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, 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, Connecticut 06070, is principal underwriter and
distributor of the Contracts. HSD is an affiliate of ITT Hartford, is registered
with the SEC as a broker-dealer, and is a member of the National Association of
Securities Dealers, Inc. ("NASD"). ITT Hartford pays HSD for acting as principal
underwriter under a distribution agreement. The Contracts are offered on a
continuous basis and ITT Hartford does not anticipate discontinuing the offer.
 
    Applications for Contracts are solicited by agents who are licensed by
applicable state insurance authorities to sell ITT 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 Payments made (up to a maximum of
  %). 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.

                       ILLUSTRATIONS OF ANNUITY PAYMENTS
                     ASSUMING HYPOTHETICAL RATES OF RETURN
 
    The following graphs have been prepared to show how investment performance
affects Variable Annuity Payments over time. These illustrations assume that the
Contract is a Non-Qualified Contract. 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:  %,
 %, and   %.) These are hypothetical rates of return and, of course, ITT
Hartford does not guarantee that any Payee will earn these returns for any one
year or any sustained period of time. THE TABLES ARE FOR ILLUSTRATIVE PURPOSES
ONLY AND DO NOT REPRESENT PAST OR FUTURE RETURNS.
 
    The Annuity Payments illustrated reflect the deduction of all fees and
expenses. Fund management fees and operating expenses are assumed to be at an
annual rate of  % of their average daily net assets. This is the weighted
average of Fund expenses shown in the fee table on page __. Actual fees and
expenses under the Contract may be higher or lower, will vary from year to year,
and will depend upon the portion of the Payments supported by each Sub-Account
selected by the Contract Owner or Payee. The mortality and expense risk charge
is assumed to be at an annual rate of 1.25% of each Sub-Account's average daily
net assets.
 
    Variable Annuity Payments may be more or less than those shown if the actual
returns of the Sub-Accounts selected are different than those illustrated. Since
it is very likely that a Contract's investment return will fluctuate over time,
one can expect Variable Annuity Payments to fluctuate. The total amount of
Annuity Payments ultimately received will depend upon how long the Annuitant
lives and whether or not the Contract Owner selects an Annuity Payment Option
with a guaranteed number of years.
 
    Another factor that determines the amount of Variable Annuity Payments is
the Assumed Investment Return. Generally, Variable Annuity Payments will
increase in size from 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.

                         USING HISTORIC RATES OF RETURN
 
    The following graphs have been prepared to show how investment performance
affects Variable Annuity Payments over time. These illustrations assume that the
Contract is a Non-Qualified Contract.
 
    The Variable Annuity Payments shown reflect the actual investment return
after all expenses over the periods indicated. SUCH RATES OF RETURN ARE NOT
PROJECTIONS OR INDICATIONS OF FUTURE RESULTS AND ITT HARTFORD DOES NOT GUARANTEE
THAT ANY CONTRACT WILL EARN THESE OR SIMILAR RETURNS FOR ANY PERIOD OF TIME. THE
TABLES ARE FOR ILLUSTRATIVE PURPOSES ONLY AND DO NOT REPRESENT FUTURE INVESTMENT
RETURNS.
 
    Variable Annuity Payments may be more or less than those shown if the actual
returns of the Sub-Accounts selected are different than those illustrated. Since
it is very likely that a Contract's investment return will fluctuate over time,
one can expect Variable Annuity Payments to fluctuate. The total amount of
Annuity Payments ultimately received will depend upon how long the Annuitant
lives and whether or not the Contract Owner selects an Annuity Payment Option
with a guaranteed number of years.
 
    Another factor that determines the amount of Variable Annuity Payments is
the Assumed Investment Return. 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.

                           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 1.00008098, 
1.0000____, and 1.0000____, 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 Value and the amount of several Variable 
Annuity Payments based on one Subaccount.

    ILLUSTRATIONS OF ANNUITY PAYMENTS ASSUMING HYPOTHETICAL RATES OF RETURN

   The following tables have been prepared to show how investment performance 
affects Variable Annuity Payments over time. These illustrations assume that 
the Contract is a Non-Qualified Contract. 

   The Variable Annuity Payments reflect three different assumptions for a 
constant investment return after all expenses: 0%, 6%, and 12%. (Net of all 
expenses, these contract returns are: __%, __%, and __%.)  These are 
hypothetical rates of return and, of course, Hartford Life does not guarantee 
that any Payee will earn these returns for any one year or any sustained 
period of time. THE TABLES ARE FOR ILLUSTRATIVE PURPOSES ONLY AND DO NOT 
REPRESENT PAST OR FUTURE RETURNS.

   The Annuity Payments illustrated reflect the deduction of all fees and 
expenses. Fund management fees and operating expenses are assumed to be at an 
annual rate of __% of  their average daily net assets. This is the weighted 
average of Fund expenses shown in the fee table on page __. Actual fees and 
expenses under the Contract may be higher or lower, will vary from year to 
year, and will depend upon the portion of the Payments supported by each 
Sub-Account selected by the Contract Owner or Payee. The mortality and expense 
risk charge is assumed to be at an annual rate of 1.25% of each Sub-Account's 
average daily net assets. 

   Variable Annuity Payments may be more or less than those shown if the 
actual returns of the Sub-Accounts selected are different than those 
illustrated. Since it is very likely that a Contract's investment return will 
fluctuate over time, one can expect Variable Annuity Payments to fluctuate. 
The total amount of Annuity Payments ultimately received will depend upon how 
long the Annuitant lives and whether or not the Contract Owner selects an 
Annuity Payment Option with a guaranteed number of years.

   Another factor that determines the amount of Variable Annuity Payments is 
the Assumed Investment Return. Generally, Variable Annuity Payments will 
increase in size from 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.

   Upon request ITT Hartford will furnish a customized illustration based on 
the Contract Owner's individual circumstances (and/or those of the selected 
Annuitant) and choice of Annuity Payment Options.

        ILLUSTRATIONS OF ANNUITY PAYMENTS USING HISTORIC RATES OF RETURN

   The following tables have been prepared to show how investment performance 
affects Variable Annuity Payments over time. These illustrations assume that 
the Contract is a Non-Qualified Contract. 

   The Variable Annuity Payments shown reflect the actual investment return 
after all expenses over the periods indicated. SUCH RATES OF RETURN ARE NOT 
PROJECTIONS OR INDICATIONS OF FUTURE RESULTS AND ITT HARTFORD DOES NOT 
GUARANTEE THAT ANY CONTRACT WILL EARN THESE OR SIMILAR RETURNS FOR ANY PERIOD 
OF TIME. THE TABLES ARE FOR ILLUSTRATIVE PURPOSES ONLY AND DO NOT REPRESENT 
FUTURE INVESTMENT RETURNS.

   Variable Annuity Payments may be more or less than those shown if the 
actual returns of the Sub-Accounts selected are different than those 
illustrated. Since it is very likely that a Contract's investment return will 
fluctuate over time, one can expect Variable Annuity Payments to fluctuate. 
The total amount of Annuity Payments ultimately received will depend upon how 
long the Annuitant lives and whether or not the Contract Owner selects an 
Annuity Payment Option with a guaranteed number of years.

   Another factor that determines the amount of Variable Annuity Payments is 
the Assumed Investment Return. 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 Annuity Payments illustrated reflect the deduction of all fees and 
expenses. Fund management fees and operating expenses are assumed to be at an 
annual rate of __% of  their average daily net assets. This is the weighted 
average of Fund expenses shown in the fee table on page __. Actual fees and 
expenses under the Contract may be higher or lower, will vary from year to 
year, and will depend upon the portion of the Payments supported by each 
Sub-Account selected by the Contract Owner or Payee. The mortality and expense 
risk charge is assumed to be at an annual rate of 1.25% of each Sub-Account's 
average daily net assets. 

   Upon request ITT Hartford will furnish a customized illustration based on 
the Contract Owner's individual circumstances (and/or those of the selected 
Annuitant) and choice of Annuity Payment Options.

Item 28. Indemnification

         The directors and officers of ITT Hartford and Hartford Securities
         Distribution Company, Inc. ("HSD") are covered under a directors and
         officers liability insurance policy issued to ITT Hartford 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.

         The Registrant hereby undertakes that 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, or otherwise, 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 connection with the
         securities being registered, the Registrant will, unless in the opinion
         of its counsel the matter has been settled by controlling 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:  ITT Hartford Life and Annuity Insurance Company Separate Account One
     Immediate Variable Annuity
     --------------------------

Dear Sir/Madam:

I have acted as General Counsel to ITT Hartford Life and Annuity Insurance
Company (the "Company"), a Connecticut insurance company, and ITT 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- 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.
