                                   PROSPECTUS
                               Dated May 1, 1999
 
             Individual Flexible Payment Variable Annuity Contracts
 
                                   Issued By
 
                            MONY Variable Account A
                          MONY Life Insurance Company
 
MONY Life Insurance Company issues the flexible payment variable annuity
contract described in this prospectus. Among the contract's many terms are:
 
Allocation of Purchase Payments and Cash Value
 
- - You can tell us what to do with your purchase payments. You can also tell us
  what to do with the fund value your contract may create for you resulting from
  those purchase payments.
 
    - You can tell us to place them into a separate account. That separate
      account is called MONY Variable Account A.
 
       - If you do, you can also tell us to place your purchase payments and
         fund values into any or all of 14 different subaccounts. Each of these
         subaccounts seeks to achieve a different investment objective. If you
         tell us to place your purchase payment into one or more of the
         subaccounts of the separate account, you bear the risk that the
         investment objectives will not be met. That risk includes your not
         earning any money on your purchase payments and fund values and also
         that your purchase payments and fund values may lose some or all of
         their value.
 
    - You can also tell us to place some or all of your purchase payments and
      fund values into our account. Our account is called the Guaranteed
      Interest Account with Market Value Adjustment. If you do, we will pay not
      less than 4.5% interest annually, and we will guarantee that those
      purchase payments and fund values will not lose any value, so long as you
      leave the purchase payments and fund values in the Account. Purchase
      payments and fund values you place into the Guaranteed Interest Account
      with Market Value Adjustment become part of our assets.
 
Living Benefits
 
    - Annuity Benefits
 
     - This contract is designed to pay to you the fund value in periodic
       installments. Those installments could be for your lifetime, or on other
       bases, such as for a fixed period.
 
       - You may chose the date on which this benefit starts. That date must be
         at least 10 years from the date the contract was issued.
 
    - Fund Value Benefits
 
       - You may ask for some or all of the contract's fund value at any time.
         If you do, we may deduct a surrender charge. If you have allocated
         purchase payments or fund values to the Guaranteed Interest Account
         with Market Value Adjustment, we may also deduct a market value
         adjustment.
 
    - Loans
 
       - You may borrow up to 50% of the fund value of the contract if you are a
         qualified retirement plan. You will have to pay interest to us on the
         amount borrowed.
 
Death Benefit
 
- - We will pay to your beneficiary upon the death of the person you name as
  annuitant before the annuity starting date the greater of:
 
    - The total of all purchase payments you made for the contract minus any
      monies you asked us to pay you back and any surrender charge and market
      value adjustment; and
 
    - The fund value of the contract on the date of the annuitant's death or an
      enhanced death benefit, if higher.
 
Fees and Charges
 
- - The contract allows us to deduct certain charges from the cash value. These
  charges are detailed in this prospectus.

                                  DEFINITIONS
 
THIS PROSPECTUS CONTAINS SOME SPECIALIZED TERMS. WE HAVE DEFINED SPECIALIZED
TERMS ON THE PAGE WHERE THEY FIRST APPEAR. THE DEFINITIONS WILL APPEAR ON THE
PAGE IN A BOX LIKE THIS ONE.
 
PURPOSE OF THE CONTRACT
 
     The Contract is an Individual Flexible Payment Variable Annuity Contract
(the "Contract" or "Contracts").
 
     The Contract is designed to allow an owner to make purchase payments to the
Company under the Contract. Those purchase payments are allocated at the owner's
choice among the subaccounts of MONY Variable Account A and the Guaranteed
Interest Account with Market Value Adjustment. Those purchase payments can
accumulate for a period of time and create fund values for the owner. The owner
can chose the length of time that such purchase payments may accumulate. The
owner may chose at some point in the future to receive annuity benefits based
upon those accumulated fund values.
 
     An owner may use the Contract's design to accumulate fund values for
various purposes including retirement or to supplement other retirement
programs. Some of these retirement programs ( the "Qualified Plans") may qualify
for federal income tax advantages available under Sections 401, 403 (other than
Section 403(b)), 408, 408A and 457 of the Internal Revenue Code (the "Code").
 
QUALIFIED PLANS -- Retirement plans that receive favorable tax treatment under
Section 401, 403, 408 or 457 of the Internal Revenue Code.
 
QUALIFIED CONTRACTS -- Contracts issued under Qualified Plans.
 
     The Contract is also designed to allow the owner to request payments of
part or all of the accumulated fund values before the owner begins to receive
annuity benefits. This payment may result in the imposition of a surrender
charge and a market value adjustment. It may also be subject to income and other
taxes.
 
PURCHASE PAYMENTS AND FUND VALUES
 
     The purchase payments you make for the Contract are received by the
Company. Currently those purchase payments are not subject to taxes imposed by
the United States Government or any state or local government.
 
     You may allocate your purchase payments to one or more of the subaccounts
of MONY Variable Account A that are available under the Contract and/or to the
Guaranteed Interest Account with Market Value Adjustment. The purchase payments
you allocate among the various subaccounts of MONY Variable Account A may
increase or decrease in value on any day depending on the investment experience
of the
 
                                        1
<PAGE>   7
 
subaccounts you select. There is no guarantee that the value of the purchase
payments you allocate to any of the subaccounts of MONY Variable Account A will
increase or that the purchase payments you make will not lose value.
 
     Purchase payments you allocate to the Guaranteed Interest Account will be
credited with interest at a rate determined by the Company. That rate will not
be less than 3.5%.
 
MONY VARIABLE ACCOUNT A
 
     MONY Variable Account A is a separate investment account of MONY Life
Insurance Company (the "Company"). MONY Variable Account A's assets are owned by
the Company, but are not chargeable with liabilities arising from any other
business the Company conducts.
 
     The subaccounts of MONY Variable Account A invest in shares of MONY Series
Fund, Inc. and The Enterprise Accumulation Trust (collectively called the
"Funds") at their net asset value. (See "The Funds" at page   ). Owners bear the
entire investment risk for all amounts allocated to MONY Variable Account A
subaccounts.
 
OWNER -- The person so designated in the application. If a Contract has been
absolutely assigned, the assignee becomes the Owner. A collateral assignee is
not the Owner.
 
PURCHASE PAYMENT (PAYMENT) -- An amount paid to the Company by the Owner or on
the Owner's behalf as consideration for the benefits provided by the Contract.
 
GUARANTEED INTEREST ACCOUNT WITH MARKET VALUE ADJUSTMENT
 
     The Guaranteed Interest Account is part of the Company's general account.
It consists of all the Company's assets other than assets allocated to
segregated investment accounts of the Company. Net Purchase Payments allocated
to the Guaranteed Interest Account will be credited with interest at rates
guaranteed by the Company for specified periods. (See "Guaranteed Interest
Account" at page   .)
 
MARKET VALUE ADJUSTMENT
 
     A market value adjustment will be imposed on transfers or surrenders
(partial or full) from the Guaranteed Interest Account. The adjustment can be
either a positive or negative adjustment. No adjustment is made for the amount
withdrawn or transferred within 30 days before the end of the accumulation
period, nor to benefits paid as a result of the death of the Owner. The
Guaranteed Interest Account and its market value adjustment feature are
described in a separate prospectus which accompanies this prospectus.
 
FUND VALUE -- The aggregate dollar value as of any Business Day of all amounts
accumulated under each of the subaccounts, the Guaranteed Interest Account, and
the Loan Account of the Contract. If the term Fund Value is preceded or followed
by the terms subaccount(s), the Guaranteed Interest Account, and the Loan
Account, or any one or more of those terms, Fund Value means only the Fund Value
of the subaccount, the Guaranteed Interest Account or the Loan Account, as the
context requires.
 
MINIMUM PURCHASE PAYMENTS
 
     The minimum purchase payment for individuals varies depending upon the
purchaser of the contract and the method of paying the purchase payments. See
"Payment and Allocation of Payment" on page   .
 
     Additional purchase payments of at least $100 may be made at any time.
However, for certain automatic payment plans, the smallest additional payment is
$50. (See "Issuance of the Contract" at page   .) The Company may change any of
these requirements in the future.
 
                                        2
<PAGE>   8
 
TRANSFER OF FUND VALUES
 
     You may transfer fund value among the subaccounts and to or from the
Guaranteed Interest Account. Transfers from the Guaranteed Interest Account may
be subject to a Market Value Adjustment. Transfers may be made by telephone if
the proper form has been completed, signed, and received by the Company at its
Syracuse Operations Center. See "Transfer of Fund Value", page   .
 
CONTRACT LOANS
 
     If your contract permits, you may borrow up to 50% of your Contract's fund
value from the Company. Your contract will be the only security required for the
loan. Contracts issued to Qualified Plans are generally the only Contracts which
permit loans. An amount equal to the amount of the loan is transferred to the
loan account as security for the loan. The loan account is part of the Company's
general account.
 
     We will charge you interest on the amount borrowed. If you do not pay the
interest when due, the amount due will be borrowed from the Contract's fund
value.
 
SURRENDER
 
     You may surrender all or part of the Contract at any time and receive its
cash value while the annuitant is alive prior to the annuity starting date. We
may impose a surrender charge and market value adjustment. The amounts you
receive upon surrender may be subject to income taxes. (See "Federal Tax Status"
at page   .)
 
CHARGES AND DEDUCTIONS
 
     The Contract provides for the deduction of various charges and expenses
from the fund value of the Contract. These deductions are summarized in the
table on pages   -  and discussed in greater detail beginning on page   .
 
NON-QUALIFIED CONTRACTS -- Contracts issued under Non-Qualified Plans.
 
RIGHT TO RETURN CONTRACT PROVISION
 
     You have the right to examine the Contract when you receive it. You may
return the Contract for any reason within ten days from the day you receive it..
You will receive a full refund of the purchase payments received by the Company.
During the Right to Return Contract period, purchase payments will be retained
in the Company's general account and will earn interest at a rate not less than
3 1/2% per year.
 
DEATH BENEFIT
 
     If the Annuitant (and the Secondary Annuitant, if any) dies before the date
the annuity payments start, the Company will pay a death benefit to the
Beneficiary. Under certain circumstances, an Enhanced Death Benefit may be
payable. If the Annuitant dies after annuity payments start, no death benefit is
payable except as may be payable under the settlement option selected. (See
"Death Benefit" at page   and "Enhanced Death Benefit" at page   .)
 
ANNUITANT -- The person upon whose continuation of life any annuity payment
depends and to whom annuity payments are made.
 
SECONDARY ANNUITANT -- The party designated by the Owner to become the
Annuitant, subject to certain conditions, on the death of the Annuitant.
 
BENEFICIARY -- The party entitled to receive benefits payable at the death of
the Annuitant or (if applicable) the Secondary Annuitant.

The Surrender Charge percentage, which reduces to zero as shown in the table on
page   , is determined by the Contract Year in which the surrender occurs.
 
     The Surrender Charge may be reduced under certain circumstances which
include reduction in order to guarantee that certain amounts may be received
free of surrender charge. See "Charges against Fund Value -- Free Partial
Surrender Amount" at page   .
- ---------------
  ** The Annual Contract Charge is currently $0. However, the Company may in the
     future change the amount of the charge to an amount not exceeding $50 per
     contract year. See "Charges Against Fund Value -- Annual Contract Charge",
     at page   . The Transfer Charge currently is $0. However, the Company has
     reserved the right to impose a charge for each transfer, which will not
     exceed $25. See "Charges Against Fund Value -- Transfer Charge" at page  .

 *** The Mortality and Expense Risk charge is deducted daily equivalent to a
     current annual rate of 1.25 percent (and is guaranteed not to exceed a
     daily rate equivalent to an annual rate of 1.35%) from the value of the net
     assets of the Separate Account.
 
**** Expenses also include custodial credit percentages as follows: Intermediate
     Term Bond --     %; Long Term Bond --     %; Government
     Securities --     %; and Money Market  --     %.
 
   + The name, but not the investment objectives or policies, of the Small Cap
     Portfolio was changed effective May 1, 1998 to the Small Company Value
     Portfolio.
 
  ++ The Sub-accounts corresponding to these Portfolios first became available
     for allocation in November 1998.
 
 +++ These expenses reflect expense reimbursements in effect on May 1, 1995.
     Absent these expense reimbursements, expenses would have been as follows:
     Equity --     %; Small Cap --     %; Managed --     %; International
     Growth --     %; and High Yield Bond --     %. The Equity, Small Cap, and
     Managed Portfolio reimbursements relate to mutual fund accounting expense.
 
The purpose of the Table of Fees beginning on page   is to assist the Owner in
understanding the various costs and expenses that the Owner will bear, directly
or indirectly. The table reflects the expenses of the separate account as well
as of MONY Series Fund, Inc. and Enterprise Accumulation Trust. MONY Series
Fund, Inc. and the Enterprise Accumulation Trust have provided information
relating to their respective operations. The expenses borne by the Separate
Account are explained under the caption "Charges and Deductions" at page   of
this Prospectus. The expenses borne by the MONY Series Fund, Inc. are explained
under the caption "Investment Management Arrangements and Expenses" at page   of
the accompanying prospectus for MONY Series Fund, Inc.. The expenses borne by
the Enterprise Accumulation Trust assume that the expense reimbursements in
effect on and after May 1, 1990 for the Equity, Small Cap, and Managed
Portfolios which limit the total annual expenses to 1.00% of average net assets
and expense reimbursements which, on and after November 16, 1994 (commencement
of operations), limit the total annual expenses of the International Growth
Portfolio to 1.55% of average net assets and the High Yield Bond Portfolio to
..85% of average net assets, will continue throughout the period shown and are
explained under the caption "Management of the Fund" at page   of the
accompanying prospectus for the Accumulation Trust. Effective on and after May
1, 1996 and at least through April 1, 1999, as a part of the increase in
investment advisory fees, the investment adviser has agreed to reimburse the
Accumulation Trust for expenses which exceed .95% of the average daily net
assets of the Equity, Small Cap, and Managed Portfolios of the Trust. The table
does not reflect income taxes or penalty taxes which may become payable under
the Internal Revenue Code or premium or other taxes which may be imposed under
state or local laws.

                     DETAILED INFORMATION ABOUT THE COMPANY
                          AND MONY VARIABLE ACCOUNT A
 
MONY LIFE INSURANCE COMPANY
 
     MONY Life Insurance Company issues the Contract. In this prospectus, MONY
Life Insurance Company is called the Company. The Company is a stock life
insurance company organized in the State of New York.. The Company is currently
licensed to sell life insurance and annuities in all 50 states, the District of
Columbia, Puerto Rico, and the U.S. Virgin Islands.
 
     The principal office of the Company is located at 1740 Broadway, New York,
New York. The Company was organized as a mutual life insurance company under the
laws of the State of New York in 1842 under the name The Mutual Life Insurance
Company of New York. In 1998, The Mutual Life Insurance Company of New York
converted to a stock company through demutualization and was renamed MONY Life
Insurance Company. The demutualization did not have any material effect on MONY
Variable Account A or the Contract.
 
     At January 1, 1999, the rating assigned to the Company by A.M. Best
Company, Inc., an independent insurance company rating organization, was A-
(Excellent). This rating is based upon an analysis of financial condition and
operating performance through the end of 1997. The A.M. Best rating of the
Company should be considered only as bearing on the ability of the Company to
meet its obligations under the policies.
 
YEAR 2000 ISSUE
 
     The Year 2000 issue is the result of widespread use of computer programs
which use two digits (rather than four) to define a year. By use of a two-digit
field, the industry avoided the greater cost of additional mainframe capacity.
As a result, any of the Company's computer systems that have time-sensitive
software may recognize a date using "00" as the year 1900 rather than the year
2000. This could result in a major system failure or in miscalculations.
 
  State of Readiness
 
     In 1996, the Company initiated a formal Year 2000 Project to resolve the
Year 2000 issue. The scope of the Project was identified, and funding was
established. In early 1997, the Company retained Command Systems, Inc., and
Keane, Inc. to assist the Company in bringing the Company's computer and
information systems into Year 2000 compliance. The Company's overall goal for
information technology ("IT") related items is to have business-critical
hardware and software compliant by December 31, 1998, with additional testing
and enterprise end-to-end testing occurring in 1999. MONY has also retained
Technology Resource Solutions to assist in the evaluation of Year 2000 issues
affecting the Company's non-IT systems in facilities and equipment which may
contain date logic in embedded chips. MONY's overall goal is to have all non-IT
systems compliant by mid-1999.
 
     The scope of the Project includes:
 
     - ensuring the compliance of all applications, operating systems and
       hardware on mainframe, PC and LAN platforms;
 
     - ensuring the compliance of voice and data network software and hardware;
       addressing issues related to non-IT systems in buildings, facilities and
       equipment which may contain date logic in embedded chips; and
 
     - addressing the compliance of key vendors and other third parties.
 
     The phases of the Project are:
 
          (i) inventorying Year 2000 items and assigning priorities;
 
          (ii) assessing the Year 2000 compliance of items;
 
                                        9
<PAGE>   15
 
          (iii) remediating or replacing items that are determined not to be
     Year 2000 compliant;
 
          (iv) testing items for Year 2000 compliance; and
 
          (v) designing and implementing Year 2000 contingency and business
     continuity plans.
 
     To determine that all IT systems (whether internally developed or
purchased) are Year 2000 compliant, each system is tested using a standard
testing methodology which includes unit testing, baseline testing, and future
date testing. Future date testing includes critical dates near the end of 1999
and into the year 2000, including leap year testing. For business-critical
non-IT systems in buildings, facilities and equipment, approximately 50% had
been remediated as of September 30, 1998.
 
     The inventory and assessment phases of the Project were completed prior to
mid 1998. At December 31, 1998, approximately      % of the Company's
application systems had been remediated, tested and re-implemented into
production. Approximately      % of the operating systems, systems software, and
hardware for mainframe, PC and LAN platforms were deemed compliant based on
information supplied by vendors verbally, in writing, or on the vendor's
Internet site. Of the IT business critical items, approximately      % were
compliant and tested by December 31, 1998. Approximately      % of non-IT
business critical items had been remediated as of December 31, 1998. Ongoing
testing for Year 2000 compliance will continue in 1999, and is expected to be
completed by mid-1999.
 
     As part of the Project, significant service providers, vendors, suppliers,
and other third parties that are believed to be critical to business operations
after January 1, 2000, have been identified and steps are being undertaken in an
attempt to reasonably ascertain their stage of Year 2000 readiness through

     The estimated total cost of the Year 2000 Project is approximately $26.0
million. The total amount expended on the Project through December 31, 1998 was
$          million which includes $          million for external vendor costs,
and $          million for internal costs. The estimated future cost of
completing the Year 2000 Project is estimated to be approximately $
million, which includes $          million for external vendor costs, and
$          million for internal costs. These amounts include costs associated
with the current development of contingency plans.
 
  Risks
 
     The Company believes that completed and planned modifications and
conversions of its internal systems and equipment will allow it to be Year 2000
compliant in a timely manner. There can be no assurance, however, that the
Company's internal systems or equipment or those third parties on which the
Company relies will be Year 2000 compliant in a timely manner or that the
Company's or third parties' contingency plans will mitigate the effects of any
noncompliance. The failure of the systems or equipment of the Company or third
parties (which the Company believes is the most reasonable likely worst case
scenario) could affect the distribution and sale of life insurance, annuity and
investment products and could have a material effect on the Company's financial
position and results of operations.
 
  Contingency Plans
 
     The Company has retained outside consultants to assist in the development
of Business Continuity Plans, which includes identification of third party
service providers, information systems, equipment, facilities, and other items
which are mission critical to the operation of the business. In conjunction with
this effort, the Company is developing a Year 2000 Contingency Plan to address
failures due to the Year 2000 problem of third parties and other items, which
are critical to the ongoing operation of the business. The Contingency Plan
includes the performance of alternate processing as well as consideration for
changing third party service providers, vendors, and suppliers if necessary. The
scheduled date for completion of the Contingency Plan is mid 1999. The Company
believes that due to the pervasive nature of potential Year 2000 issues, the
 
                                       10

contingency planning process is an ongoing one that will require further
modifications as the Company obtains additional information regarding the status
of third party Year 2000 readiness.

     The investment objectives of each portfolio are fundamental and may not be
changed without the approval of the holders of a majority of the outstanding
shares of the portfolio affected. For each of the Funds a majority means the
lesser of:
 
          (1) 67% of the portfolio shares represented at a meeting at which more
     than 50% of the outstanding portfolio shares are represented, or
 
          (2) More than 50% of the outstanding portfolio shares.
 
     Each Owner should periodically review their allocation of purchase payments
and Cash Values among the subaccounts and the guaranteed interest account in
light of their current objectives, the current market conditions, and the risks
of investing in each of the Funds' various portfolios. A full description of the
objectives, policies, restrictions, risks and expenses for each of the Funds'
portfolios can be found in the accompanying prospectus for each of the Funds.
The prospectus for each of the Funds should be read together with this
prospectus.
 
PURCHASE OF PORTFOLIO SHARES BY MONY VARIABLE ACCOUNT A
 
     MONY Variable Account A will buy and redeem shares from the Funds at net
asset value. Shares will be redeemed when needed for the Company to:
 
     - Collect charges under the Contracts.
 
     - Pay Cash Value on full surrenders of the Contracts.
 
     - Fund partial surrenders.
 
     - Provide benefits under the Contracts.
 
     - Transfer assets from one subaccount to another or between one or more
       subaccounts of MONY Variable Account A and the Guaranteed Interest
       Account as requested by Owners.
 
Any dividend or capital gain distribution received from a portfolio of a Fund
will be:
 
     - Reinvested immediately at net asset value in shares of that portfolio.
 
     - Kept as assets of the corresponding subaccount.
 
                                       17
<PAGE>   23
 
CASH VALUE -- The Contract's Fund Value, less (1) any applicable Surrender
Charge, (2) any outstanding loan, and (3) any applicable market value
adjustment.
 
     The Board of Directors of MONY Series Fund, Inc. and the Board of Trustees
of The Enterprise Accumulation Trust monitor the respective Fund for the
existence of material irreconcilable conflict between the interests of variable
annuity Owners and variable life insurance Owners. The Boards shall report any
such conflict to the boards of the Company and its affiliates. The Boards of
Directors of the Company and its affiliates have agreed to be responsible for
reporting any potential or existing conflicts to the Directors and Trustees of
each of the Funds. The Boards of Directors of the Company and its affiliates
will remedy any conflict at their own cost. The remedy may include establishing
a new registered management investment company and segregating the assets
underlying the variable annuity contracts and the variable life insurance
contracts.
 
GUARANTEED INTEREST ACCOUNT
 
     The Guaranteed Interest Account is a part of the Company's General Account
and consists of all the Company's assets other than assets allocated to
segregated investment accounts of the Company, including MONY Variable Account
A.
 
     Crediting of Interest.  The entire initial purchase payment always earns
interest at a rate not less than 3.5% per year until the end of the Right to
Return Contract period. When the Right to Return Contract period ends, the
entire initial purchase payment plus interest earned is transferred to the
selected subaccounts and Guaranteed Interest Account accumulation periods.
 
     Any Net Purchase Payments you as Owner of the Contract allocate to the
Guaranteed Interest Account will be credited with interest at the rate declared
by the Company. The Company guarantees that the rate credited will not be less
than 3.5% (0.009426%, compounded daily). If you allocate purchase payments (or
transfer funds) to the Guaranteed Interest Account, you will choose between
accumulation periods of 3, 5, 7, or 10 years. Before the beginning of each
calendar month, the Company will declare interest rates for each period, if
those rates will be higher than the guaranteed rate. Each interest rate declared
by the Company will be applicable for all Net Purchase Payments received or
transfers from MONY Variable Account A completed within the period during which
it is effective. Purchase payments you allocate to the Accumulation Period you
select will receive this interest rate for the entire period. Within 45 days,
but not less than 15 days before the Accumulation Period expires, we will notify
you of the new rates we are then declaring. When the period expires you can
elect an accumulation period of 3, 5, 7, or 10 years or may elect to transfer
the entire amount allocated to the expiring accumulation period to the separate
account. If you make no election, the entire amount allocated to the expiring
accumulation period will automatically be held for an accumulation period of the
same length. If that period will extend beyond the maturity date or if that
period is no longer offered, the money will be transferred into the Money Market
subaccount.
 
     Surrenders.  When you as Contract Owner request Contract Fund Values from
the Guaranteed Interest Account be transferred to MONY Variable Account A,
surrendered, loaned to you, or used to pay any charge imposed in accordance with
the Contract, you must tell the Company the source by interest rate accumulation
period of amounts you request be transferred, surrendered, loaned, or used to
pay charges.
 
     Market Value Adjustment.  Amounts taken from the Guaranteed Interest
Account because of partial and full surrenders or transfers from the Guaranteed
Interest Account are subject to Market Value Adjustment. This Adjustment is
determined by multiplying the amount of the surrender or transfer from each
accumulation period and interest rate by the following factor:
 
                         [(1 + a)/(1 + b)](n-t)/12) - 1
 
where
 
        a = rate declared at the beginning of accumulation period
 
                                       18
<PAGE>   24
 
        b = rate then currently declared for an accumulation period equal to the
            time remaining in the guaranteed period, plus 0.25%
 
        n = guaranteed period in months
 
        t = number of elapsed months (or portion thereof) in the guaranteed
period
 
     If an Accumulation Period equal to the time remaining is not issued by the
Company, the rate will be an interpolation between two available Accumulation
Periods. If two such Periods are not available, we will use the rate for the
next available Accumulation Period.
 
     Market Value Adjustments do not apply for partial or full surrenders or
transfers requested within 30 days of the end of the accumulation period, nor to
any benefits paid upon the death of the Annuitant. The Market Value Adjustment
does apply to benefits paid upon death of the Owner.
 
     The Guaranteed Interest Account and its Market Value Adjustment feature are
described in greater detail in a separate prospectus attached to this prospectus
for your convenience.
 
                     DETAILED INFORMATION ABOUT THE POLICY
 
     The Fund Value in MONY Variable Account A and in the Guaranteed Interest
Account with Market Value Adjustment provide many of the benefits of your
Contract. The information in this section describes the benefits, features,
charges and major provisions of the Contract and the extent to which those
depend upon the Fund Value, particularly the Fund Value in MONY Variable Account
A. Attached to this prospectus is a prospectus describing the Guaranteed
Interest Account with Market Value Adjustment and its various features, charges
and major provisions.

Additional purchase payments of at least $100 may be made at any time. However,
for certain automatic payment plans, the smallest additional payment is $50.
 
     The Company reserves the right to revise its rules from time to time to
specify different minimum Purchase Payments. In addition, the prior approval of
the Company is needed before it will accept a Purchase Payment if, with that
Payment:
 
          (1) Cumulative Purchase Payments made under any one or more Contracts
     held by the Contract Owner, less
 
          (2) The amount of any prior partial surrenders and their Surrender
     Charges, exceed
 
          (3) $1,500,000.
 
     The Company reserves the right to reject an application for any reason
permitted by law.
 
     Net Purchase Payments received before the Effective Date will be held in
the Company's General Account and will be credited with interest at not less
than 3.5% per year if:
 
          (1) The Contract is issued by the Company, and
 
          (2) The Contract is accepted by the Owner.
 
No interest will be paid if the Contract is not issued or if it is declined by
the Owner. Net Purchase Payments will be held in the Company's General Account
if:
 
          (1) The application is approved,
 
          (2) The Contract is issued, and
 
          (3) The Owner accepts the Contract.
 
These amounts will be held in that Account pending end of the Right to Return
Contract Period. (See "Free Look Privilege" on page   .) Interest will be
credited on amounts held in the General Account beginning on the date the
amounts are received. Amounts are received on the day of actual receipt at the
Company's Operation Center. The prospective buyer will be told the reasons for
the delay, the initial Purchase Payment will be returned in full and the
application declined if:
 
          (1) The application is not complete when received, and
 
          (2) The application is not completed within 5 days.
 
                                       20
<PAGE>   26
 
The application will not be declined if the prospective buyer consents to the
Company's keeping the Purchase Payment until the application is completed.
 
  Right to Return Contract Provision
 
     The Owner may return the Contract within 10 days of the delivery date. The
Contract must be returned to the Company or any agent of the Company. When the
Company receives the Contract, it will be voided as if it were never in effect.
The amount to be refunded is equal to all purchase payments received by the
Company.
 
  Allocation of Payments and Fund Value
 
     Allocation of Payments.  On the application, the Owner may allocate Net
Purchase Payments to the subaccount(s) of MONY Variable Account A or to the
Guaranteed Interest Account. Net Purchase Payments (and any interest thereon)
are held in the General Account if they are received before the end of the Right
to Return Contract Period. The Net Purchase Payments will earn interest at a
rate not less than 3.5% per year beginning on the later of:
 
          (1) The Effective Date of the Contract, and
 
          (2) The date the Payment is received at the Company's Operations
     Center.
 
     Net Purchase Payments will continue to earn 3.5% annual interest until the
Right to Return Contract Period expires. (See "Right to Return Contract
Provision above.) After the Right to Return Contract Period has expired, the
Contract's Fund Value will automatically be transferred to MONY Variable Account
A subaccount(s) or to the Guaranteed Interest Account according to the Owner's
percentage allocation.
 
     After the Right to Return Contract Period, under a non-automatic payment
plan, if the Owner does not:
 
          (1) Specify the amount to be allocated among subaccounts, or
 
          (2) Specify the percentage to be allocated among subaccounts, or
 
          (3) The amount or percentage specified is incorrect or incomplete,
 
the Net Purchase Payments will be allocated under the Owner's most recent
instructions on record with the Company. The amount specified must not be less
than $10.00 and the percentage specified must not be less than 10% of the
Payment. For automatic payment plans, Net Purchase Payments will be allocated
according to the Owner's most recent instructions on record.
 
     The Owner may change the specified allocation formula for future Net
Purchase Payments at any time without charge by sending written notification to
the Company at the Operations Center. Prior allocation instructions may also be
changed by telephone subject to the rules of the Company and its right to
terminate telephone allocation. The Company reserves the right to deny any
telephone allocation request. If all telephone lines are busy (for example,
during periods of substantial market fluctuations), Owners may be unable to
request telephone allocation changes by telephone. In such cases, an Owner would
submit a written request. Any such change, whether made in writing or by
telephone, will be effective when recorded on the records of the Company, in
accordance with the requirements of state insurance departments and the
Investment Company Act of 1940. The Company has adopted rules relating to
changes of allocations by telephone which, among other things, outlines
procedures designed, and which the Company believes are reasonable, to prevent
unauthorized instructions. If these procedures are followed:
 
          (1) The Company shall not be liable for any loss as a result of
     following fraudulent telephone instructions, and
 
          (2) The Owner will therefore bear the entire risk of loss due to
     fraudulent telephone instructions.
 
A copy of the rules and the Company's form for electing telephone allocation
privileges is available from licensed agents of the Company who are registered
representatives of MSC or by calling 1-800-487-6669. The
 
                                       21
<PAGE>   27
 
Company's form must be signed and received at the Company's Operations Center
before telephone allocation instructions will be accepted.
 
     Net Purchase Payments may be allocated in whole percentages to any number
of the available subaccounts and to the Guaranteed Interest Account. Allocations
must be in whole percentages, and no allocation may be for less than 10% of a
Net Purchase Payment. Allocation percentages must total 100%.
 
     When allocated Purchase Payments are received they are credited to
subaccounts of MONY Variable Account A in the form of Units. The number of Units
is determined by dividing the dollar amount allocated to a particular subaccount
by the unit value for that subaccount for the Business Day on which the Purchase
Payment is received.
 
  Calculating Unit Values for Each Subaccount
 
     The unit value of each subaccount on its first Business Day was set at
$10.00. The Company computes the unit value of a subaccount on any later
Business Day as follows:
 
          (1) Calculate the value of the shares of the portfolio belonging to
     the subaccount as of the close of business that Business Day. This
     calculation is done before giving effect to any policy transactions for
     that day, such as purchase payments or surrenders. For this purpose, the
     net asset value per share reported to the Company by the managers of the
     portfolio is used.
 
          (2) Add the value of any dividends or capital gains distributions
     declared and reinvested by the portfolio during the valuation period.
     Subtract from this amount a charge for taxes, if any.
 
          (3) Subtract a charge for the mortality and expense risk assumed by
     the Company under the policy. If the previous day was not a Business Day,
     then the charge is adjusted for the additional days between valuations.
 
          (4) Divide the resulting amount by the number of units held in the
     subaccount on the Business Day before the purchase or redemption of any
     units on that date.
 
     The unit value of these subaccounts may increase, decrease or remain the
same from Business Day to Business Day. The Unit value depends on the investment
performance of the portfolio of the Fund in which the subaccount invests and any
expenses and charges deducted from MONY Variable Account A. The Owner bears the
entire investment risk. Owners should periodically review their allocations of
payments and values in light of market conditions and overall financial planning
requirements.
 
  Calculation of Guaranteed Interest Account Fund Value
 
     Net Purchase Payments to be allocated to the Guaranteed Interest Account
will be credited to the accumulation period chosen by the Contract Owner on:
 
          (1) The date received at the Operations Center, or
 
          (2) If the day Payments are received is not a Business Day, then on
     the next Valuation Date.
 
Interest will be credited daily. That part of a Net Purchase Payments allocated
to the Guaranteed Interest Account that exceeds the $250,000 limit imposed by
the Company will be returned to the Owner.
 
  Calculation of Fund Value
 
     The Contract's Fund Value will reflect:
 
     - The investment performance of the selected subaccount(s) of MONY Variable
       Account A.
 
     - Amounts credited (including interest) to the Guaranteed Interest Account.
 
     - Any Net Purchase Payments.
 
     - Any Partial Surrenders.
 
                                       22
<PAGE>   28
 
     - All Contract charges (including surrender charges) imposed.
 
There is no guaranteed minimum Fund Value, except to the extent Net Purchase
Payments have been allocated to the Guaranteed Interest Account. Because a
Contract's Fund Value at any future date will be dependent on a number of
variables, it cannot be predetermined.
 
     The Fund Value will be computed first on the Effective Date and thereafter
on each Business Day. On the Effective Date, the Contract's Fund Value will be
the Net Purchase Payments received plus any interest credited on those Payments
during the period when Net Purchase Payments are held in the General Account.
(See "Issuance of the Contract" at page   .)
 
     After allocation of the amounts in the General Account to MONY Variable
Account A or the Guaranteed Interest Account, on each Business Day, the
Contract's Fund Value will be computed as follows:
 
          (1) Determine the aggregate of the Fund Values attributable to the
     Contract in each of the subaccounts on the Business Day. This is done by
     multiplying the subaccount's Unit value on that date by the number of
     subaccount Units allocated to the Contract;
 
          (2) Add any amount credited to the Guaranteed Interest Account. This
     amount is the aggregate of all Net Purchase payments and:
 
           - The addition of any interest credited.
 
           - Addition or subtraction of any amounts transferred.
 
           - Subtraction of any partial surrenders.
 
           - Subtraction of any Contract charges, deductions, and any Market
             Value
 
          (3) Add the value attributable to any loan account;
 
          (4) Add any Net Purchase Payment received on that Business Day;
 
          (5) Subtract any partial surrender amount and its Surrender Charge
     made on that Business Day;
 
          (6) Subtract any Annual Contract Charge deductible on that Business
     Day.
 
     In computing the Contract's Fund Value, the number of subaccount Units
allocated to the Contracts is determined after any transfers among subaccounts
or between one or more of the subaccounts and the Guaranteed Interest Account.
Any transfer charges are also deducted. However, the computation of the
Contract's Fund Value is done before any other Contract transactions on the
Business Day, such as:
 
     - Receipt of Net Purchase Payments.
 
     - Partial Surrenders.
 
If a transaction would ordinarily require that the Contract's Fund Value be
computed for a day that is not a Business Day, the next following Business Day
will be used.
 
     Transfers.  You may transfer the value of the Contract among the
subaccounts after the Right to Return Contract Period has expired by sending a
proper written request to the Company's Operations Center. Transfers may be made
by telephone if you have proper authorization. See "Allocations of Premium and
Fund Value," page   . Currently, there are no limitations on the number of
transfers between subaccounts.
 
     A transfer charge is not currently imposed on transfers. (See "Charges
Against Fund Value -- Transfer Charge" at page   .) However, the Company
reserves the right to impose a charge which will not exceed $25 per transfer. If
imposed the charge will be deducted from the first subaccount(s) or the
Guaranteed Interest Account from which the amounts are transferred. This charge
is in addition to the amount transferred. All transfers in a single request are
treated as one transfer transaction. A transfer resulting from the first
reallocation of Fund Value at the end of the Right to Return Contract Period
will not be subject to a transfer charge. Under present law, transfers are not
taxable transactions.
 
                                       23
<PAGE>   29
 
CONTRACT YEAR -- Any period of twelve (12) months commencing with the Effective
Date and each Contract Anniversary thereafter.
 
     Transfers Involving the Guaranteed Interest Account.  Transfers may be made
from the Guaranteed Interest Account at any time, but, if they are made before
the end of the 3, 5, 7, or 10 year accumulation period there will be a Market
Value Adjustment. If the transfer request is received within 30 days before the
end of the Accumulation Period, no market value adjustment will apply.
 
TERMINATION OF THE CONTRACT
 
     The Contract will remain in effect until the earlier of:
 
          (1) The date the Contract is surrendered in full,
 
          (2) The date annuity payments start,
 
          (3) The Contract Anniversary on which, after deduction for any Annual
     Contract Charge then due, no Fund Value in the subaccounts and the
     Guaranteed Interest Account remains in the Contract, and
 
          (4) The date the Death Benefit is payable under the Contract.
 
CONTRACT ANNIVERSARY -- An anniversary of the Effective Date of the Contract.
 
EFFECTIVE DATE -- The date shown as the Effective Date of the Contract.
 
                                   SURRENDERS
 
     The Owner may elect to make a surrender of all or part of the Contract's
value provided it is:
 
     - On or before the annuity payments start, and
 
     - During the lifetime of the Annuitant.
 
     Any such election shall specify the amount of the surrender. The surrender
will be effective on the date a proper written request is received by the
Company at its Operation Center.
 
     The amount of the surrender may be equal to the Contract's Cash Value,
which is its Fund Value less
 
          (1) any applicable Surrender Charge,
 
          (2) any applicable Market Value Adjustment, and
 
          (3) any Outstanding Debt.
 
The Surrender may also be for a lesser amount (a "partial surrender"). Requested
partial surrenders that would leave a Fund Value of less than $1,000 are treated
and processed as a full surrender. In such case, the entire Cash Value will be
paid to the Owner. For a partial surrender, any Surrender Charge or any
applicable Market Value Adjustment will be in addition to the amount requested
by the Owner.
 
MARKET VALUE ADJUSTMENT -- An amount added to or deducted from the amount
surrendered or transferred from the Guaranteed Interest Account for Contracts
issued in certain states.
 
ACCUMULATION PERIOD -- Currently 3, 5, 7 and 10 years. The Period starts on the
Business Day that falls on, or next follows the date the purchase payment is
transferred into the Guaranteed Interest Account and ends on the monthly
contract anniversary immediately prior to the last day of that Period.
 
                                       24
<PAGE>   30
 
     A surrender will result in the cancellation of Units and the withdrawal of
amounts credited to the Guaranteed Interest Account accumulation periods as
chosen by the Owner. The aggregate value of the surrender will be equal to the
dollar amount of the surrender plus, if applicable, any Surrender Charge and any
applicable Market Value Adjustment. For a partial surrender, the Company will
cancel Units of the particular subaccounts and withdraw amounts from the
Guaranteed Interest Account accumulation period under the allocation specified
by the Owner. Allocations may be by either amount or percentage. Allocations by
percentage must be in whole percentages (totaling 100%). At least 10% of the
partial surrender must be allocated to any subaccount designated by the Owner.
The request will not be accepted if:
 
     - There is insufficient Fund Value in the Guaranteed Interest Account or a
       subaccount to provide for the requested allocation against it, or
 
     - The request is incorrect.
 
     Any surrender charge will be allocated against the Guaranteed Interest
Account and each subaccount in the same proportion that each allocation bears to
the total amount of the partial surrender.
 
     Any cash surrender amount will be paid in accordance with the requirements
of state insurance departments and the Investment Company Act of 1940. .
However, the Company may be permitted to postpone such payment under the 1940
Act. Postponement is currently permissible only for any period during which
 
          (1) the New York Stock Exchange is closed other than customary weekend
     and holiday closings, or
 
          (2) trading on the New York Stock Exchange is restricted as determined
     by the Securities and Exchange Commission, or
 
          (3) an emergency exists as a result of which disposal of securities
     held by the Fund is not reasonable practicable or it is not reasonably
     practicable to determine the value of the net assets of the Fund, or
 
          (4) for such other periods as the Securities and Exchange Commission
     may by order permit for the protection of Owners.
 
     Any cash surrender involving payment from amounts credited to the
Guaranteed Interest Account may be postponed, at the option of the Company, for
up to 6 months from the date the request for a surrender or proof of death is
received by the Company. Surrenders involving payment from the Guaranteed
Interest Account may in certain circumstances and in certain states also be
subject to a Market Value Adjustment, in addition to a surrender charge. The
Owner may elect to have the amount of a surrender settled under one of the
Settlement Options of the Contract. (See "Annuity Provisions" at page   .)
 
     Contracts offered by this prospectus may be issued in connection with
retirement plans meeting the requirements of certain sections of the Internal
Revenue Code. Owners should refer to the terms of their particular retirement
plan for any limitations or restrictions on cash surrenders.
 
     The tax results of a cash surrender should be carefully considered. (See
"Federal Tax Status" at page   .)
 
                                     LOANS
 
     Qualified Contracts issued under an Internal Revenue Code Section 401(k)
plan will have a loan provision. All of the following conditions apply in order
for the amount to be considered a loan, rather than a (taxable) partial
surrender:
 
     - The term of the loan must be 5 years or less.
 
     - Repayments are required at least quarterly and must be substantially
       level.
 
     - The loan amount is limited to certain dollar amounts as specified by the
       IRS.
 
     The Owner (Plan Trustee) must certify that these conditions are satisfied.
 
                                       25
<PAGE>   31
 
     In any event, the maximum outstanding loan on a contract is 50% of the Fund
Value of the subaccounts and/or the Guaranteed Interest Account. Loans are not
permitted before the end of the Right to Return Period. In requesting a loan,
the Contract Owner must specify the subaccounts from which Fund Value equal to
the amount of the loan requested will be taken. Loans from the Guaranteed
Interest Account are not taken until Fund Value in the subaccounts is exhausted.
If in order to provide the Contract Owner with the amount of the Loan requested,
Fund Values must be taken from the Guaranteed Interest Account, then the
Contract Owner must specify the Accumulation Periods from which Fund Values
equal to such amount will be taken. If the Contract Owner fails to specify
subaccounts and Accumulation Periods, the request for a loan will be returned to
a Contract Owner.
 
     Values are transferred to a loan account that earns interest at an annual
rate of 3.5%. The annual loan interest rate charged will be 6%.
 
     Loan repayments must be specifically earmarked as loan repayment and will
be allocated to the subaccounts and/or the Guaranteed Interest Account using the
most recent payment allocation on record.
 
                                 DEATH BENEFIT
 
DEATH BENEFIT PROVIDED BY THE CONTRACT
 
     The Company will pay a Death Benefit to the Beneficiary if:
 
     - The Annuitant dies; and
 
     - The death occurs before the annuity payments start.
 
     The amount of the Death Benefit will be the greater of
 
          (1) The Fund Value less any Outstanding Debt on the date of the
     Annuitant's death;
 
          (2) The Purchase Payments paid, less any partial surrenders and their
     Surrender Charges; and
 
          (3) The Enhanced Death Benefit, if any.
 
If there are funds allocated to the Guaranteed Interest Account at the time of
death, any applicable market value adjustment will be waived. If the death of
the Annuitant occurs on or after the annuity payments start, no Death Benefit
will be payable except as may be provided under the Settlement Option elected.
 
ENHANCED DEATH BENEFIT
 
     Your Contract provides for an enhanced death benefit.
 
     On the 5th Contract anniversary and each subsequent 5th Contract
anniversary prior to the Annuitant's 71st birthday (prior to the first 5th
anniversary for issue ages greater than 65), the Guaranteed Minimum Death
Benefit may be increased. If the Fund Value is greater than the current
Guaranteed Minimum Death Benefit, a new the Guaranteed Minimum Death Benefit is
equal to:
 
          1.  the Fund Value on the date the new Guaranteed Minimum Death
     Benefit is to be calculated;
 
          2.  proportionately reduced by any partial surrenders including
     surrender charges and any applicable market value adjustments assessed
     since the last recalculation of the Guaranteed Minimum Death Benefit
 
          3.  In no event will the Guaranteed Minimum Death Benefit exceed 200%
              of the total purchase payments made, reduced proportionately for:
 
             -  Each partial surrender (including surrender charges and
                applicable market value adjustments, if applicable), less
 
             -  Any Outstanding Debt.
 
                                       26
<PAGE>   32
 
     The proportionate reduction for each partial surrender will be equal to:
 
          (1) The amount of that partial surrender (including any surrender
     charges and applicable market value adjustment, if applicable, assessed),
     divided by
 
          (2) The Fund Value immediately before that partial surrender,
     multiplied by,
 
          (3) The enhanced death benefit immediately before the surrender.
 
All subaccounts are eligible for Guaranteed Minimum Death Benefit coverage.
 
     The cost of this enhancement is reflected in the mortality and expense risk
charge. Once the last value is set (prior to the Annuitant's 71st birthday or on
the first 5th anniversary if the Contract is purchased after age 65), it will
not be recalculated.
 
     All other basic death benefits as described in this prospectus continue to
apply. The largest death benefit under any of these provisions will be paid.
 
ELECTION AND EFFECTIVE DATE OF ELECTION
 
     The Owner may elect to have the Death Benefit of the Contract applied under
one of four Settlement Options to effect an annuity for the Beneficiary as payee
after the death of the Annuitant. The election must take place:
 
     - During the lifetime of the Annuitant, and
 
     - Before the annuity payments start.
 
If no election of a Settlement Option for the Death Benefit is in effect on the
date when proceeds become payable, the Beneficiary may elect
 
          (1) to receive the Death Benefit in the form of a cash payment; or
 
          (2) to have the Death Benefit applied under one of the Settlement
     Options.
 
(See "Settlement Options" at page   .) If an election by the payee is not
received by the Company within one month following the date proceeds become
payable, the payee will be considered to have elected a cash payment. Either
election described above may be made by filing a written election with the
Company in such form as it may require. Any proper election of a method of
settlement of the Death Benefit by the Owner will become effective on the date
it is signed. However, any election will be subject to any payment made or
action taken by the Company before receipt of the notice at the Company's
Operation Center.
 
     Settlement option availability may be restricted by the terms of any
applicable retirement plan and any applicable legislation for any limitations or
restrictions on the election of a method of settlement and payment of the Death
Benefit.
 
PAYMENT OF DEATH BENEFIT
 
     If the Death Benefit is to be paid in cash to the Beneficiary, payment will
be made within seven (7) days of the date
 
     - the election becomes effective, or
 
     - the election is considered to become effective, and
 
     - due proof of death is received.
 
The Company may be permitted to postpone such payment under the 1940 Act. If the
death benefit is to be paid in one sum to the Successor Beneficiary, or to the
estate of the deceased Annuitant, payment will be made within seven (7) days of
the date due proof of the death of the Annuitant and the Beneficiary is received
by the Company.

The following provides additional details of the charges and deductions under
the Contract.
 
DEDUCTIONS FROM PURCHASE PAYMENTS
 
     Deductions may be made from purchase payments for premium or similar taxes
prior to allocation of any net purchase payment among the subaccounts.
Currently, the Company makes no deduction, but may do so with respect to future
payments. If the Company is going to make deductions for such tax from future
purchase payments, it will give notice to each affected Owner.
 
CHARGES AGAINST FUND VALUE
 
  Daily Deduction from MONY Variable Account A
 
     MORTALITY AND EXPENSE RISK CHARGE
 
     The Company assumes mortality and expense risks.  A charge for assuming
such risks is deducted daily from the net assets of Variable Account A. This
daily charge from MONY Variable Account A is deducted at a current daily rate
equivalent to an annual rate of 1.25% from the value of the net assets of MONY
Variable Account A. The rate is guaranteed not to exceed a daily rate equivalent
to an annual rate of 1.35% from the value of the net assets of MONY Variable
Account A. Of the 1.25% charge, .80% is for assuming mortality risks (which is
guaranteed no to exceed .90%), and .45% is for assuming expense risks. The
charge is deducted from MONY Variable Account A, and therefore the subaccounts,
on each Business Day. These charges will not be deducted from the Guaranteed
Interest Account. Where the previous day (or days) was not a Business Day, the
deduction currently on the next Business Day will be 0.003425% (guaranteed not
to exceed 0.003699%) multiplied by the number of days since the last Business
Day. The Company reserves the right to increase the charge up to a maximum
annual rate of 1.35%.
 
                                       28
<PAGE>   34
 
     The Company believes that this level of charge is within the range of
industry practice for comparable individual flexible payment variable annuity
contracts.
 
     The mortality risk assumed by the Company is that Annuitants may live for a
longer time than projected. If that occurs, an aggregate amount of annuity
benefits greater than that projected will be payable. In making this projection,
the Company has used the mortality rates from the 1983 Table "a" (discrete
functions without projections for future mortality), with 3 1/2% interest. The
expense risk assumed is that expenses incurred in issuing and administering the
Contracts will exceed the administrative charges provided in the Contracts.
 
     The Company does not expect to make a profit from the mortality and expense
risk charge. However, if the amount of the charge exceeds the amount needed, the
excess will be kept by the Company in its general account. If the amount of the
charge is inadequate, the Company will pay the difference out of its general
account.
 
  Deductions from Cash Value
 
     Annual Contract Charge
 
     The Company has primary responsibility for the administration of the
Contract and MONY Variable Account A. An annual Contract charge helps to
reimburse the Company for administrative expenses related to the maintenance of
the Contract. Ordinary administrative expenses expected to be incurred include
premium collection, recordkeeping, processing death benefit claims and
surrenders, preparing and mailing reports, and overhead costs. In addition, the
Company expects to incur certain additional administrative expenses in
connection with the issuance of the Contract, including the review of
applications and the establishment of Contract records.
 
     The Company intends to administer the Contract itself through an
arrangement whereby it may buy some administrative services from MONY and such
other sources as may be available.
 
     Currently, there is no annual Contract charge. The Company may in the
future impose a Contract charge. The charge will never, however, exceed $50. The
Owner will receive a written notice 30 days in advance of any change in the
charge.
 
     If imposed, the Annual Contract Charge is deducted from the Fund Value on
the following dates:
 
          (1) Each Contract Anniversary before the date annuity payments start.
 
          (2) On the day the annuity payments start.
 
The amount of the charge will be allocated against the Guaranteed Interest
Account and each subaccount of MONY Variable Account A in the same proportion
that the Fund Value in those accounts bears to the Fund Value of the Contract.
The Company does not expect to make any profit from the administrative cost
deductions.
 
     Transfer Charge
 
     Contract value may be transferred among the subaccounts or to or from the
Guaranteed Interest Account and one or more of the subaccounts (including
transfers made by telephone, if permitted by the Company). The Company reserves
the right to impose a transfer charge for each transfer instructed by the Owner
in a Contract year. The transfer charge compensates the Company for the costs of
effecting the transfer. The transfer charge will not exceed $25. The Company
does not expect to make a profit from the transfer charge. If imposed, the
transfer charge will be deducted from the Contract's Fund Value held in the
subaccount(s) or from the Guaranteed Interest Account from which the first
transfer is made.
 
     Surrender Charge
 
     A contingent deferred sales charge (called a "Surrender Charge") will be
imposed when a full or partial surrender is requested or at the start of annuity
benefits if it is during the first eight years of the contract.
 
                                       29
<PAGE>   35
 
     The Surrender Charge will never exceed 7% of total Fund Value. The
Surrender Charge is intended to reimburse the Company for expenses incurred in
distributing the Contract. To the extent such charge is insufficient to cover
all distribution costs, the Company will make up the difference. The Company
will use funds from its General Account, which may contain funds deducted from
Variable Account A to cover mortality and expense risks borne by the Company.
(See "Mortality and Expense Risk Charge" at page   .)
 
     A Surrender Charge will be computed when a surrender is made and will be
deducted from the Fund Value if:
 
          (1) All or a part of the Contract's Cash Value (See "Surrenders" at
     page   ) is surrendered, or
 
          (2) The Cash Value is received at maturity when the annuity payments
     start.
 
     A Surrender Charge will not be imposed:
 
          (1) Against Fund Value surrendered after the eighth Contract Year.
 
          (2) To the extent necessary to permit the Owner to obtain an amount
     equal to the Free Partial Surrender Amount (See "Free Partial Surrender
     Amount" at page   .)
 
          (3) If the Contract is surrendered after the third Contract Year and
     the surrender proceeds are paid under either Settlement Option 3 or
     Settlement Option 3A (See "Settlement Options" at page   .)
 
     In no event will the aggregate Surrender Charge exceed 7% of the Fund
Value.
 
     For a partial surrender, the Surrender Charge will be deducted from any
remaining Fund Value, if sufficient. If the Fund Value is not sufficient, it
will be deducted from the amount surrendered. Any Surrender Charge will be
allocated against the Guaranteed Interest Account and each subaccount of
Variable Account A in the same proportion that the amount of the partial
surrender allocated against those accounts bears to the total amount of the
partial surrender.
 
     No Surrender Charge will be deducted from Death Benefits except as
described in "Death Benefit" at page      .
 
     Amount of Surrender Charge.  The amount of the Surrender Charge is equal to
a varying percentage of Fund Value during the first 8 Contract years. The
percentage is determined by multiplying the Surrender Charge Percentage for the
Contract Year by the amount of Fund Value requested as follows:

The amount of the Surrender Charge is in addition to any Market Value Adjustment
that may be made if the surrender is made from Fund Value in the Guaranteed
Interest Account with Market Value Adjustment. See

the Guaranteed Interest Account with Market Value Adjustment which accompanies
this prospectus for further details.
 
     Free Partial Surrender Amount.  The surrender charge may be reduced by
using the Free Partial Surrender Amount provided for in the Contract. The
surrender charge will not be deducted in the following circumstances:
 
          (1) For Qualified Contracts, (other than Contracts issued for IRA and
     SEP-IRA), an amount up to the greater of:
 
             (a) $10,000 (but not more than the Contract's Fund Value), or
 
             (b) 10% of the Contract's Fund Value (at the beginning of the
        Contract year, except if the surrender is requested during the first
        Contract Year, then 10% of the Contract's Fund Value at the time the
        surrender is requested)
 
             may be received in each Contract Year without a surrender charge
 
          (2) For Non-Qualified Contracts (and Contracts issued for IRA and
     SEP-IRA), an amount up to 10% of the Fund Value of the Contract may be
     received in each Contract Year without a surrender charge.
 
Contract Fund Value here means the Fund Value at the beginning of the contract
year in the subaccounts (and the Guaranteed Interest Account not the Loan
Account). This reduction of Surrender Charge does not affect a Market Value
Adjustment that may be made if the surrender is made from Fund Value in the
Guaranteed Interest Account with Market Value Adjustment. See "Guaranteed
Interest Account -- Surrenders" at page      and the prospectus for the
Guaranteed Interest Account with Market Value Adjustment which accompanies this
prospectus for further details.
 
  Taxes
 
     Currently, no charge will be made against MONY Variable Account A for
federal income taxes. However, the Company may make such a charge in the future
if income or gains within MONY Variable Account A will incur any federal income
tax liability. Charges for other taxes, if any, attributable to MONY Variable
Account A may also be made. (See "Federal Tax Status" at page      .)
 
  Investment Advisory Fee
 
     Because MONY Variable Account A purchases shares of the Funds, the net
assets of MONY Variable Account A will reflect the investment advisory fee and
other expenses incurred by the Funds. See "Table of Fees" beginning at page
     for a table which shows the fees and expenses incurred during 1998 and "The
Funds -- MONY Series Fund, Inc." and "The Funds -- Enterprise Accumulation
Trust" at pages      -

                               ANNUITY PROVISIONS
 
ANNUITY PAYMENTS
 
     Annuity payments under a Contract will begin on the date that is selected
by the Owner when the Contract is applied for. The date chosen for the start of
annuity payments may be:
 
          (1) No earlier than the Contract Anniversary after the Annuitant's
     10th birthday, and
 
          (2) No later than the Contract Anniversary after the Annuitant's 95th
     birthday.
 
                                       31
<PAGE>   37
 
     The minimum number of years from the Effective Date to the start of annuity
payments is 10. The date when annuity payments start may be:
 
          (1) Advanced to a date that is not earlier than the 10th Contract
     Anniversary.
 
          (2) Deferred from time to time by the Owner by written notice to the
     Company.
 
     The date when annuity payments start will be advanced or deferred if:
 
          (1) Notice of the advance or deferral is received by the Company prior
     to the current date for the start of annuity payments.
 
          (2) The new start date for annuity payments is a date which is not
     later than the Contract Anniversary after the Annuitant's 95th birthday.
 
A particular retirement plan may contain other restrictions.
 
     When annuity payments start, unless Settlement Option 3 or 3A is elected,
the Contract's Cash Value, less any state taxes which may be imposed upon
annuitization, will be applied to provide an annuity or any other option
previously chosen by the Owner and permitted by the Company. If Settlement
Option 3 or 3A is elected, the Contract's Fund Value (less any state taxes
imposed upon annuitization) will be applied to provide an annuity. A
supplementary contract will be issued. That contract will describe the terms of
the settlement. No payments may be requested under the Contract's surrender
provisions after annuity payments start. No surrender will be permitted except
as may be available under the Settlement Option elected.
 
     For Contracts issued in connection with retirement plans, reference should
be made to the terms of the particular retirement plan for any limitations or
restrictions on when annuity payments start.
 
ELECTION AND CHANGE OF SETTLEMENT OPTION
 
     During the lifetime of the Annuitant and prior to the start of annuity
payments, the Owner may elect:
 
          - One or more of the Settlement Options described below, or
 
          - Another settlement option as may be agreed to by the Company.
 
The Owner may also change any election if written notice of the change is
received by the Company at its Operation Center prior to the start of annuity
payments. If no election is in effect when annuity payments start, a lump sum
payment will be considered to have been elected.
 
     Settlement Options may also be elected by the Owner or the Beneficiary as
provided in the Death Benefit and Surrender sections of this Prospectus. (See
"Death Benefit" at page      and "Surrenders" at page      .)
 
     Where applicable, reference should be made to the terms of a particular
retirement plan and any applicable legislation for any limitations or
restrictions on the options that may be elected.
 
SETTLEMENT OPTIONS
 
     Proceeds settled under the Settlement Options listed below or otherwise
currently available will not participate in the investment experience of the
Variable Account.
 
     Settlement Option 1 -- Interest Income:  Interest on the proceeds at a rate
(not less than 2 3/4 percent per year) set by the Company each year.
 
     Settlement Option 2 -- Income for Specified Period:  Fixed monthly payments
for a specified period of time, as elected. The payments may, at the Company's
option, be increased by additional interest each year.
 
     Settlement Option 3 -- Single Life Income:  Payments for the life of the
payee and for a period certain. The period certain may be (a) 0 years, 10 years,
or 20 years, or (b) the period required for the total income payments to equal
the proceeds (refund period certain). The amount of the income will be
determined by the Company on the date the proceeds become payable.
 
                                       32
<PAGE>   38
 
     Settlement Option 3A -- Joint Life Income:  Payments during the joint
lifetime of the payee and one other person, and during the lifetime of the
survivor. The survivor's monthly income may be equal to either (a) the income
payable during the joint lifetime or (b) two-thirds of that income. If a person
for whom this option is chosen dies before the first monthly payment is made,
the survivor will receive proceeds instead under Settlement Option 3, with 10
years certain.
 
     Settlement Option 4 -- Income of Specified Amount:  Income, of an amount
chosen, for as long as the proceeds and interest last. The amount chosen to be
received as income in each year may not be less than 10 percent of the proceeds
settled. Interest will be credited annually on the amount remaining unpaid at a
rate determined annually by the Company. This rate will not be less than 2.75
percent per year.
 
     The Contract contains annuity payment rates for Settlement Options 3 and 3A
described in this Prospectus. The rates show, for each $1,000 applied, the
dollar amount of the monthly fixed annuity payment, when this payment is based
on minimum guaranteed interest as described in the Contract.
 
     The annuity payment rates may vary according to the Settlement Option
elected and the age of the payee. The mortality table used in determining the
annuity payment rates for Options 3 and 3A is the 1983 Table "a" (discrete
functions, without projections for future mortality), with 3.5 percent interest.
 
     Under Settlement Option 3, if income based on the period certain elected is
the same as the income provided by another available period or periods certain,
the Company will consider the election to have been made of the longest period
certain.
 
     In Qualified Plans, settlement options available to Owners may be
restricted by the terms of the plans.
 
FREQUENCY OF ANNUITY PAYMENTS
 
     At the time the Settlement Option is chosen, the payee may request that it
be paid:
 
     - Quarterly
 
     - Semiannually
 
     - Annually
 
If the payee does not request a particular installment payment, the payments
will be made in monthly installments. However, if the net amount available to
apply under any Settlement Option is less than $1,000, the Company has the right
to pay such amount in one lump sum. In addition, if the payments provided for
would be less than $25, the Company shall have the right to change the frequency
of the payments to result in payments of at least $25.
 
ADDITIONAL PROVISIONS
 
     The Company may require proof of the age of the Annuitant before making any
life annuity payment under the Contract. If the Annuitant's age has been
misstated, the amount payable will be the amount that would have been provided
under the Settlement Option at the correct age. Once life income payments begin,
any underpayments will be made up in one sum with the next annuity payment.
Overpayments will be deducted from the future annuity payments until the total
is repaid.
 
     The Contract must be returned to the Company upon any settlement. Prior to
any settlement of a death claim, proof of the Annuitant's death must be
submitted to the Company.
 
     Where any benefits under the Contract are contingent upon the recipient's
being alive on a given date, the Company require proof satisfactory to it that
such condition has been met.
 
     The Contracts described in this Prospectus contain annuity payment rates
that distinguish between men and women. On July 6, 1983, the Supreme Court held
in Arizona Governing Committee v. Norris that optional annuity benefits provided
under an employer's deferred compensation plan could not, under Title VII of the
Civil Rights Act of 1964, vary between men and women on the basis of sex.
Because of this decision, the annuity payment rates that apply to Contracts
purchased under an employment-related insurance or benefit
 
                                       33
<PAGE>   39
 
program may in some cases not vary on the basis of the Annuitant's sex. Unisex
rates to be provided by the Company will apply for Qualified Plans.
 
     Employers and employee organizations should consider, in consultation with
legal counsel, the impact of Norris, and Title VII, generally and any comparable
state laws that may apply, on any employment-related plan for which a Contract
may be purchased.
 
                          GUARANTEED INTEREST ACCOUNT
 
     The Guaranteed Interest Account is a part of the Company's General Account.
It consists of all the Company's assets other than assets allocated to
segregated investment accounts of the Company, including Variable Account A.
 
     Crediting of Interest.  The entire initial purchase payment always earns
interest at a rate not less than 3.5% per year until the end of the Right to
Return Contract Period. At such time, it is transferred to the selected
subaccounts and/or accumulation periods of the Guaranteed Interest Account. Net
Purchase Payments allocated by a Owner to the Guaranteed Interest Account will
be credited with interest at the rate declared by the Company for the specified
period selected.
 
     Net purchase payments allocated by an Owner to the Guaranteed Interest
Account will be credited with an interest rate declared by the Company. The
interest rate is guaranteed not to be less than 3.5% annually (0.0094%
compounded daily). Contract Owners who allocate purchase payments to or transfer
funds into the Guaranteed Interest Account choose between a 3, 5, 7, or 10 year
accumulation period. Prior to the beginning of each calendar month, interest
rates will be declared for each period, if more favorable than the guaranteed
rate. Each interest rate declared by the Company applies for all net purchase
payments received or transfers from the Variable Account completed within the
period during which it is effective. The purchase payment is locked in to this
interest rate for the entire duration of the period selected by the Contract
Owner. Within 45 days, but not less than 15 days before the Accumulation Period
expires, we will send notice of the new rates being declared by the Company.
When the period expires the Contract Owner can:
 
          (1) Elect an accumulation period of 3, 5, 7, or 10 years, or
 
          (2) May elect to transfer the entire amount allocated to the expiring
     accumulation period to the separate account.
 
If no election is made, the entire amount allocated to the expiring period will
automatically be held for an accumulation period of the same duration. If that
period will extend beyond the maturity date or if the period is no longer
offered, the money will be transferred into the Money Market subaccount.
 
     Surrenders.  The Contract Owner must specify the source by interest rate
accumulation period of amounts withdrawn from the Guaranteed Interest Account as
a result of a:
 
     - Transfer
 
     - Partial surrender
 
     - Loan
 
     - Any charge imposed in accordance with the Contract.
 
Partial and full surrenders or transfers from the Guaranteed Interest Account
are subject to the Market Value Adjustment. This adjustment is determined by
multiplying the amount of the surrender or transfer from each accumulation
period and interest rate by the following factor:
 
                         [(1+a) / (1+b)] (n-t)/12) - 1
 
where
 
        a = rate declared at the beginning of accumulation period
 
                                       34
<PAGE>   40
 
        b = rate then currently declared for an accumulation period equal to the
            time remaining in the guaranteed period, plus 0.25%
 
        n = guaranteed period in months
 
        t = number of elapsed months (or portion thereof) in the guaranteed
period
 
     If an Accumulation Period equal to the time remaining is not issued by the
Company, the rate will be an interpolation between two available Accumulation
Periods. If two such Periods are not available, we will use the rate for the
next available Accumulation Period.
 
     Market Value Adjustments do not apply for partial or full surrenders or
transfers requested within 30 days before the end of the accumulation period,
nor to any benefits paid upon the death of the Annuitant. The Market Value
Adjustment does apply to benefits paid upon death of the Owner.
 
                                OTHER PROVISIONS
 
OWNERSHIP
 
     The Owner has all rights and may receive all benefits under the Contract.
During the lifetime of the Annuitant (and Secondary Annuitant if one has been
named), the Owner is the person so designated in the application, unless:
 
          (1) A change in Owner is requested, or
 
          (2) A Successor Owner becomes the Owner.
 
     The Owner may name a Successor Owner or a new Owner at any time. If the
Owner dies, the Successor Owner, if living, becomes the Owner. Any request for
change must be:
 
          (1) Made in writing; and
 
          (2) Received at the Company.
 
The change will become effective as of the date the written request is signed. A
new choice of Owner or Successor Owner will not apply to any payment made or
action taken by the Company prior to the time a request for change is received.
Owners should consult a competent tax advisor prior to changing Owners.
 
SUCCESSOR OWNER -- The living person who, at the death of the Owner, becomes the
new Owner.
 
PROVISION REQUIRED BY SECTION 72(s) OF THE CODE
 
     The Contract under a Non-Qualified Plan will be surrendered as of the date
of the Owner's death if:
 
     - The Owner dies before the start of annuity payments and while the
       Annuitant is living, and
 
     - That Owner's spouse is not the Successor Owner as of the date of that
       Owner's death (as evidenced by proof satisfactory to the Company).
 
If the Successor Owner is the Beneficiary, the surrender proceeds may, at the
option of the Successor Owner, be paid over the life of the Successor Owner.
Such payments must begin no later than one year after such date of death. If the
Successor Owner is a surviving spouse, then the surviving spouse will be treated
as the new Owner of the Contract. Under such circumstances, it shall not be
necessary to surrender the Contract. If the spouse is not the Successor Owner
and there is no designated beneficiary, the proceeds must be distributed within
5 years after the date of death. However, under the terms of the Contract, if
the spouse is not the Successor Owner, the Contract will be surrendered as of
the date of death and the proceeds will be paid to the Beneficiary. This
provision shall not extend the term of the Contract beyond the date when death
proceeds become payable.
 
                                       35
<PAGE>   41
 
     Further, if the Owner dies on or after annuity payments start, then any
remaining portion of the proceeds will be distributed at least as rapidly as
under the method of distribution being used as of the date of the Owner's death.
 
PROVISION REQUIRED BY SECTION 401(a)(9) OF THE CODE
 
     The entire interest of a Qualified Plan participant under the Contract will
be distributed to the Owner or his/her Designated Beneficiary either by or
beginning not later than April 1 of the calendar year following the calendar
year in which the Qualified Plan Participant attains age 70 1/2. The
distribution will be made over the life of such Participant or the lives of such
Participant and Designated Beneficiary.
 
     If (i) distributions have begun in accordance with the previous paragraph,
and (ii) the Participant dies before the Owner's entire interest has been
distributed to him/her, 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 the Participant's death. The Contract will be surrendered as
of the Participant's death if:
 
          (1) The Participant dies before the start of such distributions, and
 
          (2) There is no designated Beneficiary.
 
The surrender proceeds must be distributed within 5 years after the date of
death. But if there is a Designated Beneficiary, the surrender proceeds may, at
the option of the Designated Beneficiary, be paid over the life of the
Designated Beneficiary. In such case, distributions will begin not later than
one year after the Participant's death. If the Designated Beneficiary is the
surviving spouse of the Participant, the date on which the distributions will
begin shall not be earlier than the date on which the Participant would have
attained age 70 1/2. If the surviving spouse dies before distributions to
him/her begin, the provisions of this paragraph shall be applied as if the
surviving spouse were the Participant. If the Plan is an IRA under Section 408
of the Code, the surviving spouse may elect to forgo distribution and treat the
IRA as his/her own plan.
 
     It is the Owner's responsibility to assure that distribution rules imposed
by the Code will be met. Qualified Plan Contracts include those qualifying for
special treatment under Sections 401, 403, 408 and 408A of the Code.
 
SECONDARY ANNUITANT
 
     Except where the Contract is issued in connection with a Qualified Plan, a
Secondary Annuitant may be designated by the Owner. Such designation may be made
once before annuitization, either
 
          (1) in the application for the Contract, or
 
          (2) after the Contract is issued, by written notice to the Company at
     its Operation Center.
 
The Secondary Annuitant may be deleted by written notice to the Company at its
Operation Center. A designation or deletion of a Secondary Annuitant will take
effect as of the date the written election was signed. The Company, however,
must first accept and record the change at its Operations Center. The change
will be subject to any payment made by the Company or action taken by the
Company from the Contract automatically by the Company as of the Contract
Anniversary following the Secondary Annuitant's 95th birthday.
 
     On the death of the Annuitant, the Secondary Annuitant will become the
Annuitant, under the following conditions:
 
          (1) the death of the Annuitant must have occurred before the Annuity
     Commencement Date;
 
          (2) the Secondary Annuitant is living on the date of the Annuitant's
     death;
 
          (3) if the Annuitant was the Owner on the date of death, the Successor
     Owner must have been the Annuitant's spouse; and
 
                                       36
<PAGE>   42
 
          (4) if the date annuity payments start is later than the Contract
     Anniversary nearest the Secondary Annuitant's 95th birthday, the date
     annuity payments start will be automatically advanced to that Contract
     Anniversary.
 
     Effect of Secondary Annuitant's Becoming the Annuitant.  If the Secondary
Annuitant becomes the Annuitant at the death of the Annuitant, in accordance
with the conditions specified above, the Death Benefit proceeds will be paid to
the Beneficiary only on the death of the Secondary Annuitant. If the Secondary
Annuitant was the Beneficiary on the Annuitant's death, the Beneficiary will be
automatically changed to the person who was the Successor Beneficiary on the
date of death. If there was no Successor Beneficiary, then the Secondary
Annuitant's executors or administrators, unless the Owner directed otherwise,
will become the Beneficiary. All other rights and benefits under the Contract
will continue in effect during the lifetime of the Secondary Annuitant as if the
Secondary Annuitant were the Annuitant.
 
ASSIGNMENT
 
     The Company will not be bound by any assignment until the assignment (or a
copy) is received by the Company at its Administrative Office. The Company is
not responsible for determining the validity or effect of any assignment. The
Company shall not be liable for any payment or other settlement made by the
Company before receipt of the assignment.
 
     If the Contract is issued under certain retirement plans, then it may not
be assigned, pledged or otherwise transferred except under such conditions as
may be allowed under applicable law.
 
     Because an assignment may be a taxable event, a Owner should consult a
competent tax advisor before assigning the Contract.
 
CHANGE OF BENEFICIARY
 
     So long as the Contract is in effect, the Beneficiary or Successor
Beneficiary may be changed by written request to the Company at its Operation
Center in a form acceptable to the Company. The Contract need not be returned
unless requested by the Company. The change will take effect as of the date the
request is signed, whether or not the Annuitant is living when the request is
received by the Company. The Company will not, however, be liable for any
payment made or action taken before receipt and acknowledgement of the request
at its Operation Center.
 
SUBSTITUTION OF SECURITIES
 
     The Company may substitute shares of another mutual fund for shares of the
Funds already purchased or to be purchased in the future by Contract Purchase
Payments if:
 
          (1) the shares of any portfolio of the Funds is no longer available
     for investment by MONY Variable Account A or,
 
          (2) in the judgment of the Company's Board of Directors, further
     investment in shares of one or more of the portfolios of the Funds is
     inappropriate based on the purposes of the Contract.
 
A substitution of securities in any subaccount will take place only with prior
approval of the Securities and Exchange Commission and under such requirements
as it may impose.
 
MODIFICATION OF THE CONTRACTS
 
     Upon notice to the Owner, the Contract may be modified by the Company, but
only if such modification
 
          (1) is necessary to make the Contract or MONY Variable Account A
     comply with any law or regulation issued by a governmental agency to which
     the Company is subject or
 
          (2) is necessary to assure continued qualification of the Contract
     under the Internal Revenue Code or other federal or state laws relating to
     retirement annuities or annuity contracts or
 
                                       37
<PAGE>   43
 
          (3) is necessary to reflect a change in the operation of MONY Variable
     Account A or the subaccounts or the Guaranteed Interest Account or
 
          (4) provides additional Settlement Options or fixed accumulation
     options. In the event of any modification, the Company may make appropriate
     endorsement in the Contract to reflect such modification.
 
CHANGE IN OPERATION OF MONY VARIABLE ACCOUNT A
 
     MONY Variable Account A may be operated as a management company under the
1940 Act or it may be deregistered under the 1940 Act in the event the
registration is no longer required
 
     - at the Company's election, and
 
     - subject to any necessary vote by persons having the right to give voting
       instructions for shares of the Funds held by the subaccounts.
 
Deregistration of MONY Variable Account A requires an order by the Securities
and Exchange Commission. If there is a change in the operation of MONY Variable
Account A under this provision, the Company may make appropriate endorsement to
the Contract to reflect the change and take such other action as may be
necessary and appropriate to effect the change.
 
                                 VOTING RIGHTS
 
     All of the assets held in the subaccounts of MONY Variable Account A will
be invested in shares of the designated portfolios of the Funds. The Company is
the legal holder of these shares. As such, it has the right to vote on the
following matters:
 
          (1) Election of the Board of Directors of MONY Series Fund, Inc. or
     the Board of Trustees of The Enterprise Accumulation Trust.
 
          (2) Certain matters that are required by the 1940 Act to be approved
     or ratified by the shareholders of a mutual fund.
 
          (3) Any other matter that may be voted upon at a shareholders'
     meeting.
 
To the extent required by law, the Company will vote the shares of each of the
Funds held in MONY Variable Account A (whether or not attributable to Owners) at
shareholder meetings of each of the Funds according to the instructions received
from Owners. The number of votes will be determined as of the record date
selected by the Board of Directors or the Board of Trustees of the respective
Fund. The Company will furnish Owners with the proper forms to enable them to
give it these instructions. Currently, the Company may disregard voting
instructions under the circumstances described in the following paragraph.
 
     The Company may, if required by state insurance officials, disregard voting
instructions if those instructions would require shares to be voted to
 
     - Cause a change in the subclassification or investment objectives or
       policies of one or more of the portfolios of either or both of the Funds.
 
     - Approve or disapprove an investment adviser or principal underwriter for
       either or both of the Funds.
 
In addition, the Company itself may disregard voting instructions that would
require the above changes if the Company reasonably disapproves those changes in
accordance with applicable federal regulations. If the Company does disregard
voting instructions, it will advise Owners of that action and its reasons for
the action in the next semiannual report to Owners.
 
     Each Owner will have the equivalent of one vote per $100 of value
attributable to the Contract held in each subaccount of MONY Variable Account A,
with fractional votes for amounts less than $100. For voting purposes, this
value attributable to the Contract is equal to the Fund Value. The votes are
represented as votes per $100 of value in each subaccount of MONY Variable
Account A. These votes are converted into a
 
                                       38
<PAGE>   44
 
proportionate number of votes in shares of the corresponding portfolio of each
of the Funds. Shares for which timely voting instructions are not received from
Owners will be voted by the Company in the same proportion as those shares in
that subaccount for which instructions are received. Should applicable federal
securities laws or regulations permit, the Company may elect to vote shares of
each of the Funds in its own right.
 
     The number of corresponding shares of the portfolio for which the Owner may
give instructions is computed by:
 
          (1) Determining the value attributable to the Contract held in that
     subaccount.
 
          (2) Dividing that value by the net asset value of one share in the
     designated portfolio of the respective Fund.
 
Example:  Contract value held in subaccount =
         $540 Net asset value of portfolio shares =
         $20 per share on the record date May give instructions on 5.4 votes
          ($540 divided by $100)
         Converts into instructions on 27 shares of the Fund ($540 divided by
          $20)
 
     Matters on which Owners may give voting instructions include the following:
 
          (1) approval of any change in the Investment Advisory Agreement and
     Services Agreement, if any, for the portfolio(s) of the Fund(s)
     corresponding to the Owner's selected subaccount(s);
 
          (2) any change in the fundamental investment policies of the
     portfolio(s) corresponding to the Owner's selected subaccount(s); and
 
          (3) any other matter requiring a vote of the shareholders of either of
     the Funds.
 
Owners participating in a particular portfolio will vote separately on the
following matters pursuant to the requirements of Rule 18f-2 under the 1940 Act:
 
          (1) approval of the Investment Advisory Agreement, or
 
          (2) any change in a portfolio's fundamental investment policies
 
                         DISTRIBUTION OF THE CONTRACTS
 
     MONY Securities Corporation ("MSC"), a New York corporation which is a
wholly-owned subsidiary of the Company, will act as the principal underwriter of
the Contracts, pursuant to an underwriting agreement with the Company. MSC is a
registered broker-dealer under the Securities Exchange Act of 1934 and is a
member of the National Association of Securities Dealers. The Contracts are sold
by individuals who are registered representatives of MSC and who are licensed as
life insurance agents for the Company. The Contracts may also be sold through
other broker-dealers authorized by MSC and applicable law to do so. Commissions
and other expenses directly related to the sale of the Contract will not exceed
6.0% of Purchase Payments. Additional compensation may be paid for persistency,
sales quality, and contract size and for other services not directly related to
the sale of the Contract. Such services include the training of personnel and
the production of promotional material.
 
                               FEDERAL TAX STATUS
 
INTRODUCTION
 
     The Contracts described in this prospectus are designed for use by
retirement plans that may or may not qualify for favorable tax treatment under
the provisions of Sections 401, 403 (other than 403(b)), 408(b), and 457 of the
Code. The ultimate effect of federal income taxes on
 
     - the value of the Contract's Fund Value,
 
     - annuity payments, and
 
                                       39
<PAGE>   45
 
     - economic benefit to the Owner, Annuitant, and the Beneficiary may depend
       upon
 
     - the type of retirement plan for which the Contract is purchased, and
 
     - the tax and employment status of the individual concerned.
 
     The following discussion of the treatment of Contracts and of the Company
under the federal income tax laws is general in nature. The discussion is based
on the Company's understanding of current federal income tax laws, and is not
intended as tax advice. Any person considering the purchase of a Contract should
consult a qualified tax adviser. A more detailed description of the treatment of
the Contract under federal income tax laws is contained in the Statement of
Additional Information. THE COMPANY DOES NOT MAKE ANY GUARANTEE REGARDING ANY
TAX STATUS, FEDERAL, STATE, OR LOCAL, OF ANY CONTRACT OR ANY TRANSACTION
INVOLVING THE CONTRACTS.
 
TAX TREATMENT OF THE COMPANY
 
     Under existing federal income tax laws, the income of MONY Variable Account
A, to the extent that it is applied to increase reserves under the Contracts, is
substantially nontaxable to the Company.
 
TAXATION OF ANNUITIES IN GENERAL
 
     The Contracts offered by this prospectus are designed for use in connection
with Qualified Plans and Non-Qualified Plans. All or a portion of the
contributions to such plans will be used to make Purchase Payments under the
Contracts. In general, contributions to Qualified Plans and income earned on
contributions to all plans are tax-deferred until distributed to plan
participants or their beneficiaries. Such tax deferral is not, however,
available for Non-Qualified Plans if the Owner is other than a natural person
unless the contract is held as an agent for a natural person. Annuity payments
made as retirement distributions under a Contract are generally taxable to the
annuitant as ordinary income except to the extent of
 
     - Participant contributions (in the case of Qualified Plans), or
 
     - Owner contributions (in the case of Non-Qualified Plans).
 
Owners, Annuitants, and Beneficiaries should seek qualified advice about the tax
consequences of distributions, withdrawals, and payments under the retirement
plans in connection with which the Contracts are purchased.
 
     The Company will withhold and remit to the United States Government and,
where applicable to state governments part of the taxable portion of each
distribution made under a Contract unless the Owner or Annuitant
 
     - provides his or her taxpayer identification number to the Company, and
 
     - notifies the Company that he or she chooses not to have amounts withheld.
 
     The Technical and Miscellaneous Revenue Act of 1988 ("TAMRA") has
requirements for determining the amount includable in gross income with respect
to distributions not received as an annuity. Distributions include those
resulting from gratuitous transfers. When computing the distributions for any 12
month period, distributions from all annuity contracts issued by the same
company to the Owner (other than those issued to qualified retirement plans)
will be treated as one annuity contract. The IRS is given power to prescribe
additional rules to prevent avoidance of this rule through serial purchases of
contracts or otherwise. None of these rules is expected to affect tax-benefited
plans.
 
     Effective January 1, 1993, distributions of plan benefits from qualified
retirement plans, other than individual retirement arrangements ("IRAs"),
generally will be subject to mandatory federal income tax withholding unless
they either are:
 
          1. Part of a series of substantially equal periodic payments (at least
     annually) for
 
          - the participant's life or life expectancy,
 
          - the joint lives or life expectancies of the participant and his/her
            beneficiary,
 
                                       40
<PAGE>   46
 
          - or a period certain of not less than 10 years, or
 
          2. Required by the Code upon the participant's attainment of age
    70 1/2 or death.
 
     Such withholding will apply even if the distribution is rolled over into
another qualified plan, including an IRA. The withholding can be avoided if the
participant's interest is directly transferred by the old plan to another
eligible qualified plan, including an IRA. A direct transfer to the new plan can
be made only in accordance with the terms of the old plan. If withholding is not
avoided, the amount withheld may be subject to income tax and excise tax
penalties.
 
     Under the generation skipping transfer tax, the Company may be liable for
payment of this tax under certain circumstances. In the event that the Company
determines that such liability exists, an amount necessary to pay the generation
skipping transfer tax may be subtracted from the death benefit proceeds.
 
RETIREMENT PLANS
 
     The Contracts described in this Prospectus currently are designed for use
with the following types of retirement plans:
 
          (1) Pension and Profit Sharing Plans established by business employers
     and certain associations, as permitted by Sections 401(a) and 401(k) of the
     Code, including those purchasers who would have been covered under the
     rules governing H.R. 10 (Keogh) Plans;
 
          (2) Individual Retirement Annuities permitted by Section 408(b) of the
     Code, including Simplified Employee Pensions established by employers
     pursuant to Section 408(k);
 
          (3) Deferred compensation plans provided by certain governmental
     entities under Section 457; and
 
          (4) Non-Qualified Plans.
 
     The tax rules applicable to participants in such retirement plans vary
according to the type of plan and its terms and conditions. Therefore, no
attempt is made here to provide more than general information about the use of
Contracts with the various types of retirement plans. Participants in such plans
as well as Owners, Annuitants, and Beneficiaries are cautioned that the rights
of any person to any benefits under these plans are subject to the terms and
conditions of the plans themselves, regardless of the terms and conditions of
the Contracts. The Company will provide purchasers of Contracts used in
connection with Individual Retirement Annuities with such supplementary
information as may be required by the Internal Revenue Service or other
appropriate agency. Any person contemplating the purchase of a Contract should
consult a qualified tax adviser.
 
                                PERFORMANCE DATA
 
     We may advertise the performance of the MONY Variable Account A
subaccounts. We will also report performance to contract owners and may make
performance information available to prospective purchasers. This information
will be presented in compliance with applicable law.
 
     Performance information contained in these advertisements is based upon
historical earnings and is not indicative of future performance. The data for
each subaccount reflects the investment results of the designated portfolio of
the Fund and recurring charges and deductions borne by or imposed on the
portfolio and the subaccount. Set forth below for each subaccount is the manner
in which the data contained in such advertisements will be calculated.
 
     Money Market Subaccount.  The performance data for this subaccount will
reflect the "yield" and "effective yield". The "yield" of the subaccount refers
to the income generated by an investment in the Subaccount over the seven day
period stated in the advertisement. This income is "annualized", that is, the
amount of income generated by the investment during that week is assumed to be
generated each week over a 52 week period and is shown as a percentage of the
investment. The "effective yield" is calculated similarly, but, when annualized,
the income earned by an investment in the subaccount is assumed to be
reinvested. The
 
                                       41
<PAGE>   47
 
"effective yield" will be slightly higher than the "yield" because of the
compounding effect of this assumed reinvestment.
 
     Subaccounts other than the Money Market Subaccount.  The performance data
for these subaccounts will reflect the "yield" and "total return". The "yield"
of each of these subaccounts refers to the income generated by an investment in
that subaccount over the 30 day period stated in the advertisement and is the
result of dividing that income by the value of the subaccount. The value of each
subaccount is the average daily number of Units outstanding multiplied by the
Unit Value on the last day of the period. The "yield" reflects deductions for
all charges, expenses, and fees of both the Funds and the Variable Account other
than the Surrender Charge. "Total return" for each of these subaccounts refers
to the return a Owner would receive during the period indicated if a $1,000
Purchase Payment was made the indicated number of years ago. It reflects
historical investment results less charges and deductions of both the Funds and
MONY Variable Account A, including any Surrender Charge imposed as a result of
the full Surrender, with the distribution being made in cash rather than in the
form of one of the settlement options, at the close of the period for which the
"total return" data is given. Total return data may also be shown assuming that
the Contract continues in force (i.e., was not surrendered) beyond the close of
the periods indicated, in which case that data would reflect all charges and
deductions of both the Funds and the Variable Account other than the Surrender
Charge. Returns for periods exceeding one year reflect the average annual total
return for such period. In addition to the total return data described above
based upon a $1,000 investment, comparable data may also be shown for an
investment equal to the amount of the average purchase payment made by a
purchaser of a Contract during the prior year.
 
     Non-Standardized Performance Data.  From time to time, average annual total
return or other performance data may also be advertised in non-standardized
formats. Non-standard performance data will be accompanied by standard
performance data, and the period covered or other non-standard features will be
disclosed.
 
     Performance information for MONY Variable Account A may be compared in
advertisements, sales literature, and reports to contract owners to various
indices, including, without limitation, the Standard & Poor's 500 Indices and
the Lehman Brothers, Shearson, CDA/Wiesenberger, Russell, Merrill Lynch, and
Wilshire indices, and to various ranking services, including, without
limitation, the Lipper Annuity and Closed End Survey compiled by Lipper
Analytical Services and the VARDS report compiled by Variable Annuity Research
and Data Service and to the Consumer Price Index (a measure for inflation)in
order to provide the reader a basis for comparison of performance. Reports and
promotional literature may also contain the Company's rating or a rating of the
Company's claims paying ability as determined by firms that analyze and rate
insurance companies and by nationally recognized statistical rating
organization.

                               LEGAL PROCEEDINGS
 
     There are no legal proceedings to which MONY Variable Account A is a party.
The Company and the principal underwriter are engaged in various kinds of

total capital and surplus of the Company or the principal underwriter.
 
                              FINANCIAL STATEMENTS
 
     The financial statements for the Company should be distinguished from the
financial statements of MONY Variable Account A and should be considered only as
bearing on the ability of the Company to meet its obligations under the
Contracts. The financial statements of the Company should not be considered as
bearing on the investment performance of the assets held in MONY Variable
Account A. The financial statements of the Company and MONY Variable Account A
are included in the Statement of Additional Information.

                          MONY LIFE INSURANCE COMPANY
 
     MONY Life Insurance Company ("Company") is a stock life insurance company.
It was organized under the laws of the state of New York in 1842 as a mutual
life insurance company under the name The Mutual Life Insurance Company of New
York. The principal offices of the Company are at 1740 Broadway, New York, New
York 10019. MONY converted from a mutual life insurance company in 1998 in a
process known as demutualization. The Company had consolidated assets at the end
of 1998 of approximately $    billion. The Company is licensed to sell insurance
and annuities in all states of the United States, the District of Columbia,
Puerto Rico, the Virgin Islands and all Provinces of Canada.
 
     At May 1, 1998, the rating assigned to the Company by A.M. Best Company,
Inc., an independent insurance company rating organization, was Company A-
(Excellent) based upon an analysis of financial condition and operating
performance through the end of 1997. The A.M. Best rating of the Company should
be considered only as bearing on the ability of the Company to meet its
obligations under the Contracts.

                               FEDERAL TAX STATUS
 
INTRODUCTION
 
     The Contract is designed for use to fund retirement plans which may or may
not be Qualified Plans under the provisions of the Internal Revenue Code (the
"Code"). The ultimate effect of federal income taxes on the Contract value, on
annuity payments, and on the economic benefit to the Contractholder, Annuitant,
or Beneficiary depends on the type of retirement plan for which the Contract is
purchased and upon the tax and employment status of the individual concerned.
The discussion contained herein is general in nature and is not intended as tax
advice. Each person concerned should consult a competent tax adviser. No attempt
is made to consider any applicable state or other tax laws. Moreover, the
discussion herein is based upon the Company's understanding of current federal
income tax laws as they are currently interpreted. No representation is made
regarding the likelihood of continuation of those current federal income tax
laws or of the current interpretations by the Internal Revenue Service.
 
TAXATION OF ANNUITIES IN GENERAL
 
     Section 72 of the Code governs taxation of annuities in general. Except in
the case of certain corporate and other non-individual Contractholders, there
are no income taxes on increases in the value of a Contract until a distribution
occurs, in the form of a full surrender, a partial surrender, a death benefit,
an assignment or gift of the Contract, or as annuity payments.
 
SURRENDERS, DEATH BENEFITS, ASSIGNMENTS AND GIFTS
 
     A Contractholder who fully surrenders his or her Contract is taxed on the
portion of the payment that exceeds his or her cost basis in the Contract. For
Non-Qualified Contracts, the cost basis is generally the amount of the Purchase
Payments made for the Contract, and the taxable portion of the surrender payment
is taxed as ordinary income. For Qualified Contracts, the cost basis is
generally zero, except to the extent of non-deductible employer contributions,
and the taxable portion of the surrender payment is generally taxed as ordinary
income subject to special elective 5-year (and, for certain eligible persons,
10-year) income averaging in the case of Qualified Contracts. A Beneficiary
entitled to receive a lump sum death benefit upon the death of the Annuitant is
taxed on the portion of the amount that exceeds the Contractholder's cost basis
in the Contract. If the Beneficiary elects to receive annuity payments within 60
days of the Annuitant's death, different tax rules apply. (See "Annuity
Payments" below.)
 
     Partial surrenders received under Non-Qualified Contracts prior to
annuitization are first included in gross income to the extent Surrender Value
exceeds Purchase Payments, less prior nontaxable distributions, and the balance
is treated as a nontaxable return of principal to the Contractholder. For
partial surrenders under a Qualified Contract, payments are generally prorated
between taxable income and nontaxable return of investment.
 
     There are special rules for Qualified Plans or contracts involving 85
percent or more employee contributions. Since the cost basis of Qualified
Contracts is generally zero, however, partial surrender amounts will generally
be fully taxed as ordinary income.
 
     A Contractholder who assigns or pledges a Non-Qualified Contract is treated
as if he or she had received the amount assigned or pledged and thus is subject
to taxation under the rules applicable to surrenders. A Contractholder who gives
away the Contract (i.e., transfers it without full and adequate consideration)
to anyone other than his or her spouse is treated for income tax purposes as if
he or she had fully surrendered the Contract.
 
ANNUITY PAYMENTS
 
     The non-taxable portion of each annuity payment is determined by an
"exclusion ratio" formula which establishes the ratio that the cost basis of the
Contract bears to the total expected value of annuity payments for the term of
the annuity. The remaining portion of each payment is taxable. Such taxable
portion is taxed at
 
                                       (2)
<PAGE>   52
 
ordinary income rates. For Qualified Contracts, the cost basis is generally
zero. With annuity payments based on life contingencies, the payments will
become fully taxable once the Annuitant lives longer than the life expectancy
used to calculate the non-taxable portion of the prior payments. Conversely, a
tax deduction in the Annuitant's last taxable year, equal to the unrecovered
cost basis, is available if the Annuitant does not live to life expectancy.
 
PENALTY TAX
 
     Payments received by Contractholders, Annuitants, and Beneficiaries under
both Qualified and Non-Qualified Contracts may be subject to both ordinary
income taxes and a penalty tax equal to 10 percent of the amount received that
is includable in income. The penalty is not imposed on amounts received: (a)
after the taxpayer attains age 59 1/2; (b) in a series of substantially equal
payments made for life or life expectancy following separation from service; (c)
after the death of the Contractholder (or, where the Contractholder is not a
human being, the death of the Annuitant); (d) if the taxpayer is totally
disabled; (e) upon early retirement under the plan after the taxpayer's
attainment of age 55; or (f) which are used for certain medical care expenses.
Exceptions (e) and (f) do not apply to Individual Retirement Accounts and
Annuities and Non-Qualified Contracts. An additional exception for Non-Qualified
Contracts is amounts received as an immediate annuity.
 
INCOME TAX WITHHOLDING
 
     The Company is required to withhold federal, and, where applicable, state,
income taxes on taxable amounts paid under the Contract unless the recipient
elects not to have withholding apply. The Company will notify recipients of
their right to elect not to have withholding apply.
 
     Effective January 1, 1993, distributions of plan benefits from qualified
retirement plans, other than individual retirement arrangements ("IRAs"),
generally will be subject to mandatory federal income tax withholding unless
they either are:
 
          1. Part of a series of substantially equal periodic payments (at least
     annually) for the participant's life or life expectancy, the joint lives or
     life expectancies of the participant and his/her beneficiary, or a period
     certain of not less than 10 years; or
 
          2. Required by the Code upon the participant's attainment of age
    70 1/2 or death.
 
     Such withholding will apply even if the distribution is rolled over into
another qualified plan, including an IRA. The withholding can be avoided if the
participant's interest is directly transferred by the old plan to another
eligible qualified plan, including an IRA. A direct transfer to the new plan can
be made only in accordance with the terms of the old plan. If withholding is not
avoided, the amount withheld may be subject to income tax and excise tax
penalties.
 
DIVERSIFICATION STANDARDS
 
     The United States Secretary of the Treasury has the authority to set
standards for diversification of the investments underlying variable annuity
contracts (other than pension plan contracts). The Secretary of the Treasury has
issued certain regulations. Further regulations may be issued. The Funds are
designed to be managed to meet the diversification requirements for the Contract
as those requirements may change from time to time. The Company intends to
satisfy those requirements so that the Contract will be treated as an annuity
contract.
 
     The Secretary of the Treasury has announced that he expects to issue
regulations or Revenue Rulings that will prescribe the circumstances in which a
Contractholder's control of the investments of a segregated asset account may
cause the Contractholder, rather than the insurance company, to be treated as
the owner of the assets of the account. The regulations or Revenue Rulings could
impose requirements that are not reflected in the Contract. The Company,
however, has reserved certain rights to alter the Contract and investment
alternatives so as to comply with such regulations or Revenue Rulings. Since the
regulations or Revenue Rulings have not been issued, there can be no assurance
as to the content of such regulations or
 
                                       (3)
<PAGE>   53
 
Revenue Rulings or even whether application of the regulations or Revenue
Rulings will be prospective. For these reasons, Contractholders are urged to
consult with their own tax advisers.
 
QUALIFIED PLANS
 
     The Contract is designed for use with several types of Qualified Plans. The
tax rules applicable to participants in such Qualified Plans vary according to
the type of plan and the terms and conditions of the plan itself. Moreover, many
of these tax rules were changed by the Tax Reform Act of 1986. Therefore, no
attempt is made herein to provide more than general information about the use of
the Contract with the various types of Qualified Plans. Participants under such
Qualified Plans as well as Contractholders, Annuitants, and Beneficiaries are
cautioned that the rights of any person to any benefits under such Qualified
Plans may be subject to the terms and conditions of the plans themselves,
regardless of the terms and conditions of the Contract issued in connection
therewith. Following are brief descriptions of the various types of Qualified
Plans and of the use of the Contract in connection therewith. Purchasers of the
Contract should seek competent advice concerning the terms and conditions of the
particular Qualified Plan and use of the Contract with that plan.
 
TAX-SHELTERED ANNUITIES
 
     Section 403(b) of the Code permits public school employees and employees of
certain types of charitable organizations specified in Section 501(c)(3) of the
Code and certain educational organizations to purchase annuity contracts and,
subject to certain contribution limitations, exclude the amount of Purchase
Payments from gross income for tax purposes. However, such Purchase Payments may
be subject to Social Security (FICA) taxes. These annuity contracts are commonly
referred to as "Tax-Sheltered Annuities." Effective January 1, 1989, the
Contracts have been withdrawn from sale to Qualified Plans which intend to
qualify for federal income tax advantages under Section 403(b).
 
H.R. 10 PLANS
 
     The Self-Employed Individuals Tax Retirement Act of 1962, as amended, which
is commonly referred to as "H.R. 10," permits self-employed individuals to
establish Qualified Plans for themselves and their employees. The tax
consequences to participants under such plans depend upon the plan itself. In
addition, such plans are limited by law to maximum permissible contributions,
distribution dates, and tax rates applicable to distributions. In order to
establish such a plan, a plan document, usually in prototype form pre-approved
by the Internal Revenue Service, is adopted and implemented by the employer.
 
INDIVIDUAL RETIREMENT ACCOUNTS AND ANNUITIES
 
     Section 408 of the Code permits eligible individuals to contribute to
individual retirement programs known as "Individual Retirement Accounts" and
"Individual Retirement Annuities." These Individual Retirement Accounts and
Annuities are subject to limitations on the amounts which may be contributed,
the persons who may be eligible, and on the time when distributions may
commence. In addition, distributions from certain types of Qualified Plans may
be placed on a tax-deferred basis into an Individual Retirement Account or
Annuity.
 
CORPORATE PENSION AND PROFIT-SHARING PLANS
 
     Sections 401(a) and 403(a) of the Code permit corporate employers to
establish various types of retirement plans for employees. Such retirement plans
may permit the purchase of the Contract to provide benefits under the plans.
 
CERTAIN GOVERNMENTAL ENTITIES
 
     Section 457 of the Code permits certain governmental entities to establish
deferred contribution plans. Such deferred contribution plans may permit the
purchase of the Contract to provide benefits under the plans.

                                PERFORMANCE DATA
 
MONEY MARKET SUBACCOUNT
 
     For the seven-day period ended December 31, 1998, the yield was      % and
the effective yield was      %.
 
     The yield was calculated by dividing the result of subtracting the value of
one Unit at the end of the seven day period ("Seventh Day Value") from the value
of one Unit at the beginning of the seven day period ("First Day Value") by the
First Day Value (the resulting quotient being the "Base Period Return") and
multiplying the Base Period Return by 365 divided by 7 to obtain the annualized
yield.
 
     The effective yield was calculated by compounding the Base Period Return
calculated in accordance with the preceding paragraph, adding 1 to the Base
Period Return, raising that sum to a power equal to 365 divided by 7 and
subtracting 1 from the result.
 
     As the Money Market Subaccount invests only in shares of the Money Market
Portfolio of the MONY Series Fund, Inc. ("MONY Series Fund"), the First Day
Value reflects the per share net asset value of the Money Market Portfolio
(which will normally be $1.00) and the number of shares of the Money Market
Portfolio of the MONY Series Fund held in the Money Market Subaccount. The
Seventh Day Value reflects increases or decreases in the number of shares of the
Money Market Portfolio of the MONY Series Fund held in the Money Market
Subaccount due to the declaration of dividends (in the form of shares and
including dividends (in the form of shares) on shares received as dividends) of
the net investment income and the daily charges and deductions from the
Subaccount for mortality and expense risks and a deduction for the Annual
Contract Charge imposed on each Contract Anniversary which has been pro-rated to
reflect the shortened 7-day period and allocated to the Money Market Subaccount
in the proportion that the total value of the Money Market Subaccount bore to
the total value of the Variable Account at the end of the period indicated. Net
investment income reflects earnings on investments less expenses of the Fund
including the Investment Advisory Fee (which for calculating the yield and
effective yield quoted above is assumed to be .40 percent, the fee which would
be charged based upon the amount of assets under management on the last day of
the period for which the quoted yield is stated). Not reflected in either the
yield or effective yield are surrender charges, which will not exceed 7% of
total Purchase Payments made to the Contract.

    Although MONY Variable Account A commenced operations in February 1991, the
total returns shown above reflect those operations as well as the historical

commenced operations on December 30, 1987 and the assets, reserves, and other

August 1988 for the Equity and Managed Subaccounts, September 1988 for the Small
Company Value Subaccount, March 1988 for the Intermediate Term Bond Subaccount,
February 1988 for the Long Term Bond Subaccount, December 1994 for the

Total return is not indicative of future performance.
 
     The table above assumes that a $1,000 payment was made to each Subaccount
at the beginning of the period shown, that no further payments were made, that
any distributions from the corresponding Portfolio of the Funds were reinvested,
and that the Contractholder surrendered the Contract for cash, rather than
electing commencement of annuity benefits in the form of one of the Settlement
Options available, at the end of the period shown. The total return percentages

inception (commencement of operations) of each of the Subaccounts, which is
August 1988 for the Equity and Managed Subaccounts, September 1988 for the Small
Company Value Subaccount, March 1988 for the Long Term Bond Subaccount, February
1986 for the Intermediate Term Bond Subaccount, December 1994 for the Government
Securities Subaccount, and November 1994 for the International Growth and for
the High Yield Bond Subaccounts, and November 1998 for the Equity Income, Growth
and Income, Growth, Capital Appreciation, and Small Company Growth Subaccounts.
Total return is not indicative of future performance.
 
     The table above reflects the same assumptions and results as the table
appearing on page 6, except that no contingent deferred sales (surrender) charge
has been deducted. The data reflected in the table above reflects the total
return a Contractholder would have received during that period if he did not
surrender his Contract.
 
     In addition to the total returns shown above, total returns may also be
shown for the average purchase payment made by a purchaser of the Contract. For
1997, this amount was $25,000. The following tables show total returns
calculated on the same basis as the two tables above, except that the purchase
payment is $25,000.

The 30-day yield is not indicative of future results.
 
     The yield shown in the table above is computed by subtracting from the net
investment income of the corresponding Portfolio of the respective Fund charges
and expenses imposed by the Variable Account and dividing the result by the
value of the Subaccount. For the Intermediate Term Bond and Long Term Bond
Portfolios, net investment income is the net of interest earned on the
obligation held by the Portfolio and expenses accrued for the period. Interest
earned on the obligation is determined by (i) computing the yield to maturity
based on the market value of each obligation held in the corresponding Portfolio
at the close of business on the thirtieth day of the period (or as to
obligations purchased during that 30-day period, based on the purchase price
plus accrued interest); (ii) dividing the yield to maturity for each obligation
by 360; (iii) multiplying that quotient by the market value of each obligation
(including actual accrued interest) for each day of the subsequent 30-day month
that the obligation is in the Portfolio; and (iv) totaling the interest on each
obligation. Discount or premium amortization is recomputed at the beginning of
each 30-day period and with respect to discount and premium on mortgage or other
asset-backed obligations subject to monthly payment of principal and interest,
discount and premium is amortized on the remaining security, based on the cost
of the security, to the weighted average maturity date, if available, or to the
remaining term of the security, if the weighted average maturity date is not
available. Gain or loss attributable to actual monthly paydowns is reflected as
an increase or decrease in interest income during that period.
 
     The yield shown reflects deductions for all charges, expenses, and fees of
both the Funds and the Variable Account other than the contingent deferred sales
(surrender) charge. The surrender charge will not exceed 7% of total Purchase
Payments made in the Contract Year of surrender and the preceding 7 Contract
Years.
 
     Net investment income of the corresponding Portfolio less all charges and
expenses imposed by the Variable Account is divided by the product of the
average daily number of Units outstanding and the value of one Unit on the last
day of the period. The sum of the quotient and 1 is raised to the 6th power, 1
is subtracted from the result, and then multiplied by 2.
 
YEAR TO DATE TOTAL RETURN:
 
     The tables below show total returns for the year to date (January 1, 1999
to February 12, 1999) which have not been annualized and which assume a $1,000
payment made at the beginning of the period and reflecting the same assumptions
and results as the table appearing on page 6, except, in the case of the column

ITEM 26.  [TO BE FILED BY AMENDMENT]
 
ITEM 27.  NUMBER OF CERTIFICATE OWNERS:
 
     As of December 31, 1998, MONY Variable Account A had        owners of
contracts.
 
ITEM 28.  INDEMNIFICATION
 
     The Amended and Restated By-Laws of MONY Life Insurance Company provide, in
Article XV as follows:
 
     Each person (and the heirs, executors and administrators of such person)
made or threatened to be made a party to any action, civil or criminal, by
reason of being or having been a trustee, officer, or employee of the
corporation (or by reason of serving any other organization at the request of
the corporation) shall be indemnified to the extent permitted by the law of the
State of New York and in the manner prescribed therein. To this end, and as
authorized by Section 722 of the Business Corporation Law of the State of New
York, the Board may adopt all resolutions, authorize all agreements and take all
actions with respect to the indemnification of directors and officers, and the
advance payment of their expenses in connection therewith.
 
     Insofar as indemnification for liability arising under the Securities Act
of 1933 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 for such
liabilities (other than the payment by the Registrant of expense incurred or
paid by a director, officer, or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer 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 precedent) submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Act and will be governed by the final
adjudication of such issue.
 
ITEM 29.  PRINCIPAL UNDERWRITERS
 
     (a) MONY Securities Corp. ("MSC"), a wholly-owned subsidiary of MONY Life
Insurance Company ("MONY"), is the principal underwriter of the Registrant and
also acts as principal underwriter for MONY Series Fund, Inc. (the "Fund"). MONY
acts as sub-investment adviser to the Fund through a services agreement.
 
     (b) The names, titles, and principal business addresses of the officers of
MSC are listed on Schedule A of Form BD for MSC (Registration No. 8-15289)
(originally filed on behalf of MONY Sales, Inc. on November 23, 1969) and Form
U-4 filed by each individual officer, the text of which is hereby incorporated
by reference.
 
     (c) No commissions or other compensation was received by the principal
underwriter, directly or indirectly, from or MONY Variable Account A during
fiscal year 1998 and 1997.
 
ITEM 30.  LOCATION OF ACCOUNTS AND RECORDS
 
     Accounts, books, and other documents required to be maintained by Section
31(a) of the Investment Company Act of 1940 and the Rules promulgated thereunder
