PROSPECTUS
 
   
                               DATED MAY 1, 1998
    
 
             INDIVIDUAL FLEXIBLE PAYMENT VARIABLE ANNUITY CONTRACTS
                                   ISSUED BY
 
                            MONY VARIABLE ACCOUNT A
                 THE MUTUAL LIFE INSURANCE COMPANY OF NEW YORK
 
     The Individual Flexible Payment Variable Annuity Contracts (the
"Contracts") described in this Prospectus provide for accumulation of cash value
on a variable basis and payment of annuity benefits. The Contracts are designed
for use by individuals in retirement plans that may or may not qualify for
special federal income tax treatment. The types of pension plans that may
purchase the Contracts are retirement plans which receive favorable tax
treatment under Sections 401, 403, 408, or 457 of the Internal Revenue Code.
(See "Definitions -- Qualified Plans" at page 2.)
 
     At the election of the Contractholder, purchase payments for the Contracts
will be allocated to either (i) a segregated investment account of The Mutual
Life Insurance Company of New York (the "Company"), which account has been
designated MONY Variable Account A (the "Variable Account"), or (ii) the
Guaranteed Interest Account, which is a part of the Company's General Account or
to both as the Contractholder may determine. The Variable Account invests in
shares of MONY Series Fund, Inc. and The Enterprise Accumulation Trust at their
net asset value. (See "The Funds" at page 10.) Upon the issuance of the
Contract, purchase payments for the Contracts will be allocated to the Money
Market Subaccount of the Variable Account and will be held there pending
expiration of the Free Look Period. After expiration of the Free Look Period,
the Cash Value of the Contract will automatically be transferred to one or more
of the Subaccounts of the Variable Account in accordance with the instructions
of the Contractholder. (See "PAYMENT AND ALLOCATION OF NET PURCHASE PAYMENTS" at
page 14.) Contractholders bear the complete investment risk for all amounts
allocated to the Variable Account. This Prospectus generally describes only the
variable features of the Contract. (For a summary of the Guaranteed Interest
Account, see "Guaranteed Interest Account" at page 12.) This Prospectus sets
forth the basic information that a prospective purchaser should know before
investing. Please keep this Prospectus for future reference.
 
   
     A Statement of Additional Information dated May 1, 1998, incorporated
herein by reference, and containing additional information about the Contracts,
has been filed with the Securities and Exchange Commission. The Statement of
Additional Information is available from the Company without charge upon written
request to the address shown on the request form on page 35 of this Prospectus
or by telephoning 1-800-487-6669. The Table of Contents of the Statement of
Additional Information can be found on page of this Prospectus.
    
 
     This Prospectus does not constitute an offer to sell or a solicitation of
an offer to buy the Contracts in any jurisdiction in which such may not be
lawfully made.
 
     In pursuing its investment objective, the High-Yield Bond Subaccount
purchases shares of the High Yield Bond Portfolio which may invest significantly
in lower rated bonds, commonly referred to as "Junk Bonds". Bonds of this type
are considered to be speculative with regard to the payment of interest and
return of principal. Investment in these types of securities have special risks
and therefore, may not be suitable for all investors. Investors should carefully
assess the risks associated with allocating purchase payments to this
subaccount.
 
 THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
     EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION, NOR HAS THE
        COMMISSION, OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
         ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION
            TO THE CONTRARY IS A CRIMINAL OFFENSE. THIS PROSPECTUS
              IS VALID ONLY WHEN ACCOMPANIED (OR PRECEDED) BY A
              CURRENT PROSPECTUS FOR MONY SERIES FUND, INC. AND
                      THE ENTERPRISE ACCUMULATION TRUST.

                                    SYNOPSIS
 
THE CONTRACTS
 
     The Individual Flexible Payment Variable Annuity Contracts (the
"Contracts") described in this Prospectus provide for the accumulation of values
on a variable basis or a guaranteed interest basis or a combination of both and
the payment of annuity benefits. The Contracts are designed for use in
connection with personal retirement plans, some of which (the "Qualified Plans")
may qualify for federal income tax advantages available under Sections 401, 403,
408 and 457 of the Internal Revenue Code (the "Code").
 
     Effective January 1, 1989, the Contracts offered by this Prospectus have
been withdrawn from sale in connection with Qualified Plans which intend to
qualify for federal income tax advantages available under Section 403(b) of the
Code.
 
THE VARIABLE ACCOUNT
 
     Net Purchase Payments for the Contracts will be allocated at the
Contractholder's option to Sub-accounts, made available therefor in accordance
with the terms of the Contracts, of a segregated investment account of The
Mutual Life Insurance Company of New York (the "Company"), which account has
been designated MONY Variable Account A (the "Variable Account") or to the
Guaranteed Interest Account, which 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 the Variable Account.
The Sub-accounts of the Variable Account invest in shares of MONY Series Fund,
Inc. (the "MONY Series Fund") and The Enterprise Accumulation Trust (the
"Accumulation Trust") (the MONY Series Fund and the Accumulation Trust are
collectively called the "Funds") at their net asset value. (See "The Funds" at
page 10). Contractholders bear the entire investment risk for all amounts
allocated to the Variable Account. 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
12.)
 
PURCHASE PAYMENTS
 
     For Non-Qualified Plans and individual retirement accounts and annuities
purchased by individuals under Section 408 of the Code (other than Simplified
Employee Pensions), the minimum initial Purchase Payment for the Contract is
$2,000, except that, on and after May 1, 1992, the minimum initial Purchase
Payment for individuals is $600 if Purchase Payments are made through automatic
checking account withdrawals. For H.R. 10 plans, certain corporate or
association retirement plans, Simplified Employee Pensions under Section 408 of
the Code, and annuity purchase plans sponsored by certain tax-exempt
organizations, governmental entities, or public school systems, the minimum
initial Purchase Payment is $600. Additional Purchase Payments of at least $100
may be made at any time. Different limits apply where certain automatic payment
plans are used. (See "Issuance of the Contract" at page 14.) The Company may
change any of these requirements in the future.
 
DEDUCTIONS FROM PURCHASE PAYMENTS
 
     Deductions may be made from Purchase Payments for premium or similar taxes.
Currently, the Company makes no such deduction, but may do so with respect to
future payments. The amount of the deduction will vary from state to state, but
will generally range from 0 percent to 3.5 percent of Payments. Residents of the
Commonwealth of Pennsylvania should be aware that a tax on Purchase Payments has
been adopted; however, the Company currently is assuming responsibility for
payment of this tax. In the event that the Company will begin to make deductions
for such tax from future Purchase Payments, it will give notice to each affected
Contractholder.
 
FREE LOOK PRIVILEGE
 
     Within ten days (or longer in certain states) of the day the Contract is
delivered to the Contractholder, it may be returned to the Company or to the
agent through whom it was purchased. When the Contract is
 
                                        3
<PAGE>   8
 
received by the Company, it will be voided as if it had never been in force.
Except for Contracts entered into in the Commonwealth of Pennsylvania, the
amount to be refunded is equal to the greater of: (i) all Purchase Payments; and
(ii) the Cash Value of the Contract (as of the date the returned Contract is
received at the Home Office or a local office of the Company, or by the agent
who sold the Contract, or, if returned by mail, upon being postmarked, properly
addressed, and postage prepaid) plus any deductions from Purchase Payments for
taxes applicable to annuity considerations that may have been deducted, any
mortality and expense risk charges deducted in determining the Unit value of the
Variable Account, and asset charges deducted in determining the share value of
the Fund. For Contracts entered into in the Commonwealth of Pennsylvania, the
amount to be refunded is described in clause (ii) of the immediately preceding
sentence.
 
SURRENDER CHARGE
 
     A contingent deferred sales charge (called a "Surrender Charge") will be
imposed upon requests for surrenders or commencement of annuity benefits where
the amount requested exceeds the amount of Net Purchase Payments during the
Contract Year when the surrender or commencement of annuity benefits is
requested and during the seven preceding Contract Years.
 
     The Surrender Charge, which otherwise would have been deducted, will not be
deducted to the extent necessary to permit the Contractholder to obtain, for
Qualified Contracts (other than Contracts issued for IRA and SEP-IRA) an amount
up to the greater of $10,000 (but not more than the Contract's Cash Value) or 10
percent of the Contract's Cash Value on the date the first partial surrender
request is received, and for Non-Qualified Contracts (and Contracts issued for
IRA and SEP-IRA and Qualified Contracts issued before May 1, 1994), an amount up
to 10% of the Cash Value of the Contract on the date the first partial surrender
request is received. The Company reserves the right to limit the number of
partial surrenders under this provision to 12 during any Contract Year. In
addition, the Contract details certain other circumstances under which a
surrender charge will not be imposed. The Surrender Charge is intended to
reimburse the Company for expenses incurred that are related to sales of the
Contract. In no event will the aggregate Surrender Charge exceed 7 percent of
the total Purchase Payments made in the Contract Year of the surrender and
during the 7 preceding Contract Years. (See "Charges Against Cash
Value -- Surrender Charge" at page 21.)
 
MORTALITY AND EXPENSE RISK CHARGE
 
     A Mortality and Expense Risk Charge is deducted daily from the net assets
of the Variable Account for mortality and expense risks assumed by the Company.
This daily charge is equal to a charge on an annual basis of 1.25 percent of the
net assets of the Variable Account. (See "Mortality and Expense Risk Charge" at
page 22.)
 
TRANSFER CHARGE
 
     Contract value may be transferred without charge as many as 4 times in any
Contract Year. For any additional transfer during a Contract Year, a transfer
charge is not currently imposed, but the Company has reserved the right to
impose a charge for each transfer in excess of 4, which will not exceed $25 per
transfer. If imposed, the transfer charge will be deducted from the Contract's
Cash Value. (See "Charges Against Cash Value -- Transfer Charge" at page 23.)
 
ANNUAL CONTRACT CHARGE
 
   
     On each Contract Anniversary prior to the Annuity Commencement Date, on the
Annuity Commencement Date, and on full surrender of the Contract, the Company
deducts an Annual Contract Charge from the Cash Value, to reimburse the Company
for administrative expenses relating to the maintenance of the Contract. The
charge is currently $30, but the Company may in the future change the amount of
the charge. The charge will never, however, exceed $50. For certain Qualified
Contracts (other than Contracts issued for IRA and SEP-IRA), the Annual Contract
Charge is reduced to $15 for as long as such Contracts remain Qualified
Contracts. (See "Charges Against Cash Value -- Annual Contract Charge" at page
22.)

DEATH BENEFIT
 
     In the event of death of the Annuitant (and the Contingent Annuitant, if
one has been named) prior to the Annuity Commencement Date, the Company will pay
a death benefit to the Beneficiary. If death of the Annuitant occurs after the
Annuity Commencement Date, no death benefit will be payable except as may be
payable under the settlement option selected. (See "Death Benefit" at page 20.)
 
TAX UPON SURRENDER
 
     Amounts withdrawn may be subject to income tax. In addition, a penalty tax
may be payable pursuant to the Internal Revenue Code on withdrawal of amounts
accumulated under any annuity contract. (See "Federal Tax Status" at page 20.)
 
THE MERGER
 
     Pursuant to an Agreement and Plan of Merger, entered into between MONY
Legacy Life Insurance Company ("MONY Legacy") and the Company, MONY Legacy was
merged ("Merger") into the Company on February 28, 1991. As a result of the
Merger, the Company became the depositor of, and became obligated under,
contracts issued by MONY Legacy ("Legacy Contracts") which are substantially
similar to the Contracts, and the assets, reserves, and other liabilities
allocated to the MONY Legacy Variable Account A (to which purchase payments made
for the Legacy Contracts were allocated prior to the Merger) became the assets,
reserves, and other liabilities of the Variable Account.

 **** Expenses reflect the reallocation of the fees and expenses associated with
      the computation of the net asset value of the Fund from MONY America to
      the Fund which became effective on and after October 14, 1997. Expenses
      also include custodial credit percentages as follows: Intermediate Term

      Advisory Fee" at page 23.)
    
 
   
   + These expenses reflect expense reimbursements in effect on May 1, 1995.
     Absent these expense reimbursements, expenses would have been as follows:
     Equity -- .84%; Small Cap -- .86%; Managed -- .76%, International
     Growth -- 1.19%; and High Yield Bond -- .77%. The Equity, Small Cap, and
     Managed Portfolio reimbursements relate to mutual fund accounting expense.

     The purpose of the Table of Fees beginning on page 5 is to assist the
Contractholder in understanding the various costs and expenses that the
Contractholder will bear, directly or indirectly. The table reflects the
expenses of the separate account as well as of MONY Series Fund, Inc. and The
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 20 of this Prospectus. The expenses
borne by the MONY Series Fund, Inc. are explained under the caption "INVESTMENT
MANAGEMENT ARRANGEMENTS AND EXPENSES" at page 18 of the accompanying prospectus
for MONY Series Fund, Inc. The expenses borne by The Enterprise Accumulation
Trust assumes 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 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
Enterprise Accumulation Trust. Effective on and after May 1, 1996 and at least
through April 1, 1998, as a part of the increase in investment advisory fees,
the investment adviser has agreed to reimburse The Enterprise 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.

                      THE COMPANY AND THE VARIABLE ACCOUNT
 
THE MUTUAL LIFE INSURANCE COMPANY OF NEW YORK
 
     The Mutual Life Insurance Company of New York (the "Company") is a mutual
life insurance company organized in the state of New York in 1842. The Company
is currently licensed to sell life insurance and annuities in all states of the
United States, the District of Columbia, Puerto Rico, the Virgin Islands, and
all Provinces of Canada. The Company's financial statements may be found in the
Statement of Additional Information. The principal offices of the Company are at
1740 Broadway, New York, New York 10019.
 
   
     In September 1997, the Company announced that it had begun the process of
demutualization. If completed, it is not expected that demutualization will have
any material effect on MONY Variable Account A or the Contract.
    
 
   
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 the applicable year. Such
programming was a common industry practice designed to avoid the significant
costs associated with additional mainframe computer capacity which would have
been necessary to accommodate a four digit year field. 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.
    
 
   
     The Company has conducted a comprehensive review of its computer systems to
identify the systems that be affected by the "Year 2000" issue and has developed
and implemented a plan to resolve the issue. The Company currently believes
that, with modifications to existing software and converting to new software,
the Year 2000 problem will not pose significant operational problems for the
Company's computer systems. However, if such modifications and conversions are
not completed on a timely basis, the Year 2000 problem may have a material
impact on the operations of the Company. Further, even if the Company completes
such modifications and conversions, there can be no assurance that the failure
by vendors or other third parties to solve the Year 2000 problem will not have a
material impact on the operations of the Company.
    
 
   
     MONY Series Fund and the Accumulation Trust have reviewed with their
respective investment advisers and other suppliers of services the status of
their Year 2000 issue. MONY Series Fund and the Accumulation Trust prospectuses,
which are included in the Prospectus Portfolio, contain the results of those
status reviews. See MONY Series Fund prospectus at page 20; Accumulation Trust
prospectus at page   .
    
 
MONY VARIABLE ACCOUNT A
 
     The Company established MONY Variable Account A (the "Variable Account") on
November 28, 1990, under New York law as a separate investment account. The
Variable Account holds assets that are segregated from all of the Company's
other assets and at present is used only to support individual flexible payment
variable annuity contracts. As a result of the Merger, the Variable Account
received the assets, reserves, and other liabilities of the MONY Legacy Variable
Account A, the separate account to which purchase payments made pursuant to the
Contracts were allocated prior to the Merger.
 
     The Company is the legal holder of the assets in the Variable Account and
will at all times maintain assets in the Variable Account with a total market
value at least equal to the contract liabilities for the Variable Account. The
obligations under the Contracts are obligations of the Company. Income, gains,
and losses, whether or not realized, from assets allocated to the Variable
Account, are, in accordance with the Contracts, credited to or charged against
the Variable Account without regard to other income, gains, or losses of the
Company. The assets in the Variable Account may not be charged with liabilities
which arise from any other business the Company conducts. The Variable Account's
assets may include accumulations of the charges the Company makes against
Contracts participating in the Variable Account. From time to time, any such
additional assets may be transferred in cash to the Company's General Account.
 
                                       10
<PAGE>   15
 
     The Variable Account is registered with the Securities and Exchange
Commission ("SEC") under the Investment Company Act of 1940 ("1940 Act") as a
unit investment trust, which is a type of investment company. This does not
involve any supervision by the SEC of the management or investment policies or
practices of the Variable Account. For state law purposes, the Variable Account
is treated as a part or division of the Company. There are currently 14
Sub-accounts within the Variable Account. Not all Subaccounts are available to
the Contractholder.
 
THE FUNDS
 
     Each available Subaccount of the Variable Account will invest only in the
shares of a corresponding Portfolio of MONY Series Fund, Inc. (the "MONY Series
Fund") or The Enterprise Accumulation Trust (the "Accumulation Trust") (the MONY
Series Fund and the Accumulation Trust are collectively called the "Funds"). The
Funds are registered with the SEC under the 1940 Act as open-end diversified
management investment companies. These registrations do not involve supervision
by the SEC of the management or investment practices or policies of the Funds.
Shares of the MONY Series Fund are currently sold to separate accounts of the
Company and to a life insurance company affiliate of the Company that were
established to fund certain Flexible Payment Variable Annuity contracts,
individual variable annuity contracts, Flexible Premium Variable Life Insurance
contracts, and Variable Life Insurance with Additional Premium Option contracts.
Until the close of business on June 24, 1994, shares of the MONY Series Fund
were also sold to Keynote Series Account, a separate account of the Company to
fund certain group variable annuity contracts issued by the Company. Shares of
the Accumulation Trust are currently sold to separate accounts of a life
insurance company affiliate of the Company that were established to fund certain
Flexible Payment Variable Annuity contracts and Flexible Premium Variable Life
Insurance contracts. Shares of the Funds may in the future be sold to other
separate accounts, and the Funds may in the future create new Portfolios. In
addition, the Company may make available additional Subaccounts with differing
or similar investment objectives. The Funds, or either of them, may withdraw
from sale any or all of the respective Portfolios in accordance with applicable
law.
 
     The Board of Directors of the MONY Series Fund and the Board of Trustees of
the Accumulation Trust each have undertaken to monitor the respective Fund for
the existence of any material irreconcilable conflict between the interests of
variable annuity contractholders and variable life insurance contractholders and
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, respectively, of each of the Funds and, at their own cost, to
remedy such conflict up to and including establishing a new registered
management investment company and segregating the assets underlying the variable
annuity contracts and the variable life insurance contracts.
 
     The Variable Account will purchase and redeem shares from the Funds at net
asset value. Shares will be redeemed to the extent necessary for the Company to
collect charges under the Contracts, to pay Surrender Value upon full surrenders
of the Contracts, to fund partial surrenders, to provide benefits under the
Contracts, and to transfer assets from one Subaccount to another or between one
or more Subaccounts of the Variable Account and the Guaranteed Interest Account
as requested by Contractholders. 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 and retained as assets of the corresponding
Subaccount.
 
     Investment Advisers.  The MONY Series Fund at present receives investment
advice with respect to each of its Portfolios from MONY Life Insurance Company
of America ("MONY America"), which acts as investment adviser to the MONY Series
Fund.
 
     Effective September 16, 1994, the investment adviser with respect to the
Equity, Small Cap, and Managed Portfolios of the Accumulation Trust is
Enterprise Capital Management, Inc., a wholly-owned subsidiary of MONY
("Enterprise Capital"). Enterprise Capital has entered into a sub-advisory
agreement with respect to the Equity and Managed Portfolios with OpCap Advisors,
formerly known as Quest for Value Advisors. OpCap Advisors is a subsidiary of
Oppenheimer Capital, which is a subsidiary of Oppenheimer Financial Corp. Prior
to that date, OpCap Advisors, then known as Quest for Value Advisors, served as
the
 
                                       11
<PAGE>   16
 
investment adviser to the Accumulation Trust with respect to the Equity, Small
Cap, and Managed Portfolios. The change of name was occasioned by the sale of
certain of the operations of Quest for Value Advisors to Oppenheimer Management
Corporation in November 1995. No change in the personnel responsible for the
day-to-day management of the Equity, and Managed Portfolios occurred as a result
of this change. Effective June 1, 1996, GAMCO Investors, Inc., became the
investment sub-adviser for the Small Cap Portfolio. Enterprise Capital also acts
as investment adviser with respect to the International Growth and High Yield
Bond Portfolios. It has entered into sub-investment advisory agreements as
follows: International Growth -- Brinson Partners, and High Yield
Bond -- Caywood-Scholl Capital Corporation.
 
     Investment Objectives.  The investment objectives of the Portfolios
currently available to Contractholders through corresponding Subaccounts of the
Variable Account are set forth in the accompanying prospectus for each of the
Funds and are described briefly below. There is no assurance that these
objectives will be met.
 
     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 (which, for each of the Funds means the lesser
of (1) 67 percent of the Portfolio shares represented at a meeting at which more
than 50 percent of the outstanding Portfolio shares are represented or (2) more
than 50 percent of the outstanding Portfolio shares).
 
     Each Contractholder should periodically consider the allocation among the
Subaccounts and the Guaranteed Interest Account in light of current market
conditions and the investment risks attendant to investing in each of the Funds'
various Portfolios. A full description of each of the Funds, their investment
objectives, policies and restrictions, their expenses, the risks attendant to
investing in each of the Funds' Portfolios, and other aspects of their operation
is contained in the accompanying prospectus for each of the Funds, which should
be read together with this Prospectus.
 
     The investment objectives of each of the Portfolios of the Funds and
identification of which of the Funds offers the Portfolio is as follows:
 
     Equity Portfolio:  Long term capital appreciation through investment in a
diversified portfolio of primarily equity securities selected on the basis of a
value-oriented approach to investing. The Accumulation Trust offers this
Portfolio.
 
     Small Cap Portfolio:  Capital appreciation through investments in a
diversified portfolio of equity securities of companies with market
capitalizations of under $1 billion. The Accumulation Trust offers this
Portfolio.
 
     Managed Portfolio:  Growth of capital over time through investment in a
portfolio consisting of common stocks, bonds, and cash equivalents, the
percentages of which will vary over time based on the investment manager's
assessments of relative investment values. The Accumulation Trust offers this
Portfolio.
 
     International Growth Portfolio:  Capital appreciation, primarily through a
diversified portfolio of non-United States equity securities. The Accumulation
Trust offers this Portfolio.
 
     High Yield Bond Portfolio:  Maximum current income, primarily from debt
securities that are rated BA or lower by Moody's Investors Service, Inc. or BB
or lower by Standard & Poor's Corporation. The Accumulation Trust offers this
Portfolio.
 
     Intermediate Term Bond Portfolio:  The maximum income over the intermediate
term consistent with preservation of capital, through investment in highly rated
debt securities, U.S. Government obligations, and money market instruments,
together having a dollar-weighted average life of between 4 and 8 years. The
MONY Series Fund offers this Portfolio.
 
     Long Term Bond Portfolio:  The maximum income over the longer term
consistent with preservation of capital, through investment in highly rated debt
securities, U.S. Government obligations, and money market instruments, together
having a dollar-weighted average life of more than 8 years. The MONY Series Fund
offers this Portfolio.

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 the Variable Account.
 
     Crediting of Interest.  Net Purchase Payments allocated by a Contractholder
to the Guaranteed Interest Account will be credited with interest at the rate
declared by the Company which the Company guarantees will not be less than 4%
(0.010746%, compounded daily). For Contracts issued on or after May 1, 1994 (or
on or after such later date as approval required in certain states is obtained),
the rate declared by the Company will not be less than 3.5% (0.009426%
compounded daily). Each interest rate declared by the Company will be applicable
for all Net Purchase Payments received or transfers from the Variable Account
completed within the period during which it is effective. Initial Net Purchase
Payments allocated to the Guaranteed Interest Account will be credited with
interest at the rate in effect for the date on which the Contract is issued (and
the funds transferred into the Money Market Subaccount) from and after the date
on which the Free Look Privilege expires on all funds transferred from the Money
Market Subaccount to the Guaranteed Interest Account. Amounts withdrawn from the
Guaranteed Interest Account as a result of a transfer, partial surrender, or any
charge imposed in accordance with the Contract, will be deemed to be withdrawals
of amounts (and any interest credited thereon) most recently credited to the
Guaranteed Interest Account.
 
     Prior to the expiration of the period for which a particular interest rate
was guaranteed, the Company will declare a renewal interest rate to be effective
for such succeeding period as the Company shall determine.
 
     Descriptions of the Guaranteed Interest Account are included in this
Prospectus for the convenience of the purchaser. The Guaranteed Interest Account
and the general account of the Company are not registered under the Securities
Act of 1933 or the Investment Company Act of 1940. Accordingly, neither the
general account of the Company nor the Guaranteed Interest Account are generally
subject to the provisions of these Acts; however, disclosures regarding the
Guaranteed Interest Account and the general account of the Company may be
subject to certain generally applicable provisions of the federal securities
laws relating to the accuracy and completeness of statements made in
prospectuses. The staff of the Securities and Exchange Commission has not
reviewed the disclosures in this Prospectus which relate to the Guaranteed
Interest Account and the general account of the Company.
 
                PAYMENT AND ALLOCATION OF NET PURCHASE PAYMENTS
 
ISSUANCE OF THE CONTRACT
 
     Individuals wishing to purchase a Contract must complete an application and
personally deliver it to a licensed agent of the Company who is also a
registered representative of MONY Securities Corp. ("MSC"), a wholly-owned
subsidiary of the Company, which is the principal underwriter for the Contracts,
or a registered broker-dealer which has been authorized by MSC to sell the
Contract. Except where certain automatic payment plans (i.e., government
allotment, payroll deduction, or automatic checking account withdrawal plans)
are used, the minimum initial Purchase Payment for the Contract is currently
$2,000 for Non-Qualified Plans, $2,000 for individual retirement accounts and
annuities purchased by individuals under Section 408 of the Code (other than
Simplified Employee Pensions), and $600 for H.R. 10 plans (self-employed
individuals' retirement plans under Sections 401 or 403(c) of the Code),
Simplified Employee
 
                                       13
<PAGE>   18
 
Pensions under Section 408 of the Code, and annuity purchase plans sponsored by
certain tax-exempt organizations, governmental entities, or public school
systems under Section 403(b) of the Code ("Tax Sheltered Annuities") and
deferred compensation plans under Section 457 of the Code. These minimum initial
Payments must be paid with the application for the Contract. Additional Payments
may be made at any time in the minimum amount of $100. For certain automatic
payment plans, however, the minimum additional payment is $50.
 
     Effective January 1, 1989, the Contracts offered by this Prospectus have
been withdrawn from sale in connection with Qualified Plans which intend to
qualify for federal income tax advantages available under Section 403 (b) of the
Code.
 
     Different rules apply for government allotment, payroll deduction and
automatic checking account withdrawal plans. For payroll deduction and automatic
checking account withdrawal plans, Purchase Payments must be made at an
annualized rate of $600 (i.e., $600 per year, $300 semiannually, $150 for each
quarter year, or $50 per month). For government allotment plans, the minimum
Purchase Payment is $50 per month.
 
     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 required before it will
accept a Purchase Payment where, with that Payment, cumulative Purchase Payments
made under any one or more Contracts held by the Contractholder, less the amount
of any prior partial surrenders and their Surrender Charges, exceed $1,500,000.
The prior approval of the Company is also required before it will accept that
part of a payment (or transfer) which would cause amounts credited to the
Guaranteed Interest Account to exceed $250,000 on the date of payment (or
transfer).
 
     The Company reserves the right to reject an application for any reason
permitted by law.
 
     Net Purchase Payments received before the Contract Date will be held in the
Company's General Account and will be credited with interest at not less than
3.5 percent per annum if the Contract is issued by the Company and accepted by
the Contractholder. No interest will be paid if the Contract is not issued or if
it is declined by the Contractholder. If the application is approved and the
Contract is subsequently issued and accepted by the Contractholder, then on the
Contract Date, amounts allocable to the Contract held in the Company's General
Account will be transferred to the Money Market Subaccount of the Variable
Account. These amounts will be held in that Subaccount pending expiration of the
Free Look Period. (See "Free Look Privilege" below.) For purposes of crediting
interest on amounts held in the General Account, Purchase Payments will be
treated as received on the day of actual receipt at the Company's Operations
Center. If an application is not complete when received by the Company at its
Operations Center, and if it is not made complete within 5 days, the prospective
purchaser will be informed of the reasons for the delay and the initial Purchase
Payment will be returned in full (and the application will be declined), unless
the prospective purchaser consents to the Company's retaining the Purchase
Payment until the application is made complete.
 
FREE LOOK PRIVILEGE
 
     Within the period of 10 days (or longer in certain states) following the
day the Contract is delivered to the Contractholder (the "Free Look Period"),
the Contractholder may return the Contract to the Company or to the agent
through whom it was purchased. When the Contract is received by the Company, it
will be voided as if it had never been in force. Except for Contracts issued in
the Commonwealth of Pennsylvania, the amount to be refunded is equal to the
greater of: (i) all Purchase Payments; and (ii) the Cash Value of the Contract
(as of the date the returned Contract is received at the Home Office or a local
office of the Company, or by the agent who sold the Contract, or, if returned by
mail, upon being postmarked, properly addressed, and postage prepaid) plus any
deductions from Purchase Payments for taxes, any mortality and expense risk
charges deducted in determining the Unit value of the Variable Account, and
asset charges deducted in determining the share value of the Funds. For
Contracts entered into in the Commonwealth of Pennsylvania, the amount to be
refunded is described in clause (ii) of the immediately preceding sentence.
 
                                       14
<PAGE>   19
 
ALLOCATION OF NET PURCHASE PAYMENTS AND CASH VALUE
 
     Allocation of Net Purchase Payments.  The Contractholder may allocate on
the application Net Purchase Payments to the Subaccount(s) of the Variable
Account or to the Guaranteed Interest Account. Any Net Purchase Payments
received before the end of the Free Look Period (and any interest thereon) will
initially be allocated to the Money Market Subaccount of the Variable Account on
the later of (i) the Contract Date and (ii) the date the Payment is received at
the Company's Operations Center. Net Purchase Payments will continue to be
allocated to that Subaccount until the Free Look Period expires and, if the
allocation on the application is incomplete or incorrect, a complete and correct
allocation notification is received by the Company. (See "Free Look Privilege"
above.) After the Free Look Period has expired and, if applicable, the correct
and complete allocation notification has been received, the Contract's Cash
Value held in the Money Market Subaccount will automatically be transferred to
the Subaccount(s) of the Variable Account or to the Guaranteed Interest Account
in accordance with the Contractholder's percentage allocation.
 
     After the Free Look Period, Net Purchase Payments under a nonautomatic
payment plan will be allocated in accordance with the Contractholder's most
recent instructions on record with the Company, unless the Contractholder at the
time a Purchase Payment is made specifies the amount (not less than $10.00 per
Subaccount) or the percentage (not less than 10 percent of the Payment) of the
Net Purchase Payment to be allocated among the Subaccount(s). If the specific
allocation is incorrect or incomplete, then that Net Purchase Payment will be
made in accordance with the most recent correct payment allocation on record.
For automatic payment plans, Net Purchase Payments will be allocated in
accordance with the Contractholder's most recent instructions on record.
 
     The Contractholder may change the allocation formula specified in the
initial allocation notification, or as changed in any subsequent notification,
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 allocations. The Company reserves
the right to deny any telephone allocation request. If all telephone lines are
busy (which might occur, for example, during periods of substantial market
fluctuations), contractholders might not be able to request changes in
allocation of purchase payments by telephone and would have to submit written
requests. Any such change, whether made in writing or by telephone, will be
effective not later than 7 days after notification is received. The Company has
adopted rules relating to changes of allocations by telephone, which, among
other things, outlines procedures to be followed which are designed, and which
the Company believes are reasonable, to prevent unauthorized instructions. If
these procedures are followed, the Company shall not be liable for, and the
Contractholder will therefore bear the entire risk of, any loss as a result of
the Company's following telephone instructions in the event that such
instructions prove to be fraudulent. 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 also registered representatives of MSC or by calling
1-800-487-6669. The Company's form must be signed and received at the Company's
Syracuse Operations Center before telephone allocation instructions will be
accepted.
 
     The minimum percentage of each Net Purchase Payment that may be allocated
to any Subaccount of the Variable Account or to the Guaranteed Interest Account
is 10 percent; all percentages must be expressed in whole numbers and must total
100 percent. The minimum amount of each Net Purchase Payment that may be
allocated to any Subaccount of the Variable Account or to the Guaranteed
Interest Account is $10.00.
 
     Upon receipt of a Purchase Payment, the Net Purchase Payments allocated to
Subaccounts of the Variable Account will be credited to the designated
Subaccount(s) in the form of Units. The number of Units to be credited to a
Subaccount is determined by dividing the dollar amount allocated to the
particular Subaccount by the Unit value for the particular Subaccount for the
Valuation Date on which the Purchase Payment is received.
 
                                       15
<PAGE>   20
 
     The Unit Value for each Subaccount was established at $10 for the first
Valuation Date. The Unit value for a Subaccount for any subsequent Valuation
Date is determined by subtracting (b) from (a) and dividing the result by (c),
where
 
          (a) is the per share net asset value on the Valuation Date of the Fund
     Portfolio in which the Subaccount invests times the number of such shares
     held in the Subaccount before the purchase or redemption of any shares on
     that Date;
 
          (b) is the mortality and expense risk charge accrued as of that
     Valuation Date (the daily mortality and expense risk charge is a percentage
     of the Subaccount's net asset value on the previous Valuation Date. If the
     previous day was not a Valuation Date, then the daily mortality and expense
     risk charge is the applicable percentage times the number of days since the
     last Valuation Date times the Subaccount's net asset value on the last
     Valuation Date); and
 
          (c) is the total number of Units held in the Subaccount on the
     Valuation Date before the purchase or redemption of any Units on that Date.
 
     The Unit Value for these Subaccounts may increase, decrease, or remain
constant from Valuation Date to Valuation Date, depending upon the investment
performance of the Portfolio of the Fund in which the Subaccount is invested and
any expenses and charges deducted from the Variable Account. The Contractholder
bears the entire investment risk. Contractholders should periodically review
their allocations of payments and values in light of market conditions and
overall financial planning requirements.
 
     Net Purchase Payments to be allocated to the Guaranteed Interest Account
will be credited to that account on the date of receipt at the Operations
Center, if that date is a Valuation Date, and, if not, on the next Valuation
Date. Interest will be credited daily. In the event that allocation of a Net
Purchase Payment would cause the amounts credited to the Guaranteed Interest
Account to exceed the $250,000 limit imposed by the Company, that part of a Net
Purchase Payment allocated to the Guaranteed Interest Account which equals the
difference between $250,000 and the amount credited to the Guaranteed Interest
Account on the date the allocation is to be made will be accepted (and credited
to the Guaranteed Interest Account) but the remainder of such allocation will be
returned to the Contractholder.
 
     Cash Value.  The Contract's Cash Value will reflect the investment
performance of the selected Subaccount(s) of the Variable Account, amounts
credited to the Guaranteed Interest Account, any Net Purchase Payments, any
partial surrenders, and all charges imposed in connection with the Contract.
There is no guaranteed minimum Cash Value, except to the extent Net Purchase
Payments have been allocated to the Guaranteed Interest Account, and because a
Contract's Cash Value at any future date will be dependent on a number of
variables, it cannot be predetermined.
 
     Determination of Cash Value.  The Cash Value of the Contract is determined
on each Valuation Date. The Cash Value will be calculated first on the Contract
Date and thereafter on each Valuation Date. On the Contract Date, the Contract's
Cash 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, interest will be credited to the Contract. (See "Issuance of
the Contract" at page 14.) After allocation of the amounts in the General
Account to the Variable Account or to the Guaranteed Interest Account, on each
Valuation Date, the Contract's Cash Value will be:
 
          (1) The aggregate of the Cash Values attributable to the Contract in
     each of the Subaccounts on the Valuation Date, determined for each
     Subaccount by multiplying the Subaccount's Unit value on that date by the
     number of Subaccount Units allocated to the Contract; plus
 
          (2) any amount credited to the Guaranteed Interest Account (which
     shall be the aggregate of all Net Purchase Payments, plus interest
     credited, if any, plus or minus amounts transferred, if any, less partial
     surrenders, if any, less any charges and deductions imposed in accordance
     with the Contract terms detailed in the Prospectus), plus
 
        (3) any Net Purchase Payment received on that Valuation Date; less
 
                                       16
<PAGE>   21
 
          (4) any partial surrender amount and its Surrender Charge made on that
     Valuation Date; less
 
          (5) any Annual Contract Charge deductible on that Valuation Date.
 
     In computing the Contract's Cash Value, the number of Subaccount Units
allocated to the Contract is determined after any transfers among Subaccounts
(and deduction of transfer charges) or between one or more of the Subaccounts
and the Guaranteed Interest Account, but before any other Contract transactions,
such as receipt of Net Purchase Payments and partial surrenders, on the
Valuation Date. If the Contract's Cash Value is to be calculated for a day that
is not a Valuation Date, the next following Valuation Date will be used.
 
     Transfers.  After the Free Look Period has expired, the value attributable
to the Contract may be transferred among the Subaccounts of the Variable
Account. There is no minimum amount that need be transferred. The Company will
effectuate transfers and determine all values in connection with transfers among
the Subaccounts on the date on which the transfer request is received at the
Operations Center, if that date is a Valuation Date and, if not, on the next
Valuation Date. Different provisions apply to transfers involving the Guaranteed
Interest Account. (See "Allocation of Net Purchase Payments and Cash Value --
Transfers Involving the Guaranteed Interest Account" at page 18.) Transfers may
be made by sending a written request to the Operations Center or by telephone,
subject to the rules of the Company and its right to terminate telephone
transfers. The Company reserves the right to deny any telephone transfer
request. If all telephone lines are busy (which might occur, for example, during
periods of substantial market fluctuations), Contractholders might not be able
to request transfers by telephone and would have to submit written requests. If
a written transfer request is incomplete or incorrect, no transfer will be made
and the request will be returned to the Contractholder. Telephone transfer
instructions will only be accepted if complete and correct. The Company has
adopted guidelines relating to telephone transfers which, among other things,
outlines procedures to be followed which are designed, and which the Company
believes are reasonable, to prevent unauthorized transfers. If these procedures
are followed, the Company shall not be liable for, and the Contractholder will
therefore bear the entire risk of any loss as a result of the Company's,
following telephone instructions in the event that such instructions prove to be
fraudulent. A copy of the guidelines and the Company's form for electing
telephone transfer privileges is available from licensed agents of the Company
who are also registered representatives of MSC or by calling 1-800-487-6669. The
Company's form must be signed and received at the Company's Syracuse Operations
Center before telephone transfers will be accepted.
 
     A transfer charge will not be imposed on the first 4 transfers made during
any Contract Year. (See "Charges Against Cash Value -- Transfer Charge" at page
23.) For any additional transfers during a Contract Year, a transfer charge is
not currently imposed, but the Company has reserved the right to impose a charge
for each transfer in excess of 4, which will not exceed $25 per transfer. If
imposed, the transfer charge will be deducted from the Subaccount(s) or the
Guaranteed Interest Account from which the amounts are transferred. This charge
is in addition to the amount transferred. If, however, there is insufficient
Cash Value in a Subaccount or in the Guaranteed Interest Account to provide for
its proportionate share of the charge, then the entire charge will be allocated
in the same manner as the Annual Contract Charge. (See "Charges Against Cash
Value -- Annual Contract Charge" at page 22.) All transfers included in a single
request are treated as one transfer transaction. A transfer resulting from the
first reallocation of Cash Value at the expiration of the Free Look Period will
not be subject to a transfer charge, nor will it be counted against the 4
transfers allowed in each Contract Year without charge. Under present law,
transfers are not taxable transactions.
 
     Transfers Involving the Guaranteed Interest Account.  Transfers to or from
the Guaranteed Interest Account are subject to the following limitations. The
prior approval of the Company is required before it will accept that part of a
transfer which would cause amounts credited to the Guaranteed Interest Account
to exceed $250,000. The portion of any transfer which cannot be made because of
such limitation will be allocated back to the Subaccounts designated in that
transfer as the Subaccounts from which amounts were to be transferred in the
proportion that the amount requested by the Contractholder to be transferred
from each Subaccount bears to the total amount transferred. Transfers of amounts
credited to the Guaranteed Interest Account to one or more Subaccounts may be
made once during each Contract Year, and the amount which
 
                                       17
<PAGE>   22
 
may be transferred is limited to the greater of (i) 25% of the amounts credited
to the Guaranteed Interest Account of the Contractholder on the date the
transfer would take effect or (ii) $5,000. Transfer requests involving the
Guaranteed Interest Account will be effective only on an anniversary of the
Contract Date or on a Valuation Date not more than 30 days thereafter. Requests
received not more than 10 days before the anniversary of the Contract Date will
be executed on the anniversary of the Contract Date. Requests received within 30
days after the anniversary of the Contract date will be executed on the
Valuation Date which coincides with or next follows the date the request is
received. Requests received more than thirty days before or after the
anniversary of the Contract Date will be returned to the Contractholder.
 
TERMINATION OF THE CONTRACT
 
     The Contract will remain in force until the earlier of (1) the date the
Contract is surrendered in full, (2) the Annuity Commencement Date, (3) the
Contract Anniversary on which, after deduction for any Annual Contract Charge
then due, no Cash Value remains in the Contract, and (4) the date the Death
Benefit is payable under the Contract.
 
                                   SURRENDERS
 
     At any time on or before the Annuity Commencement Date and during the
lifetime of the Annuitant, the Contractholder may elect to make a surrender of
all or part of the Contract's value. Any such election shall specify the amount
of the surrender and will be effective on the date a proper request is received
by the Company at its Operations Center.
 
     The amount of the surrender may be equal to the Contract's Surrender Value,
which is its Cash Value less (1) any applicable Surrender Charge and (2) (for a
full surrender) any Annual Contract Charge. The Surrender may also be for a
lesser amount (a "partial surrender") of at least $100. If a partial surrender
is requested, and that surrender would leave a Cash Value of less than $1,000,
then that partial surrender will be treated and processed as a full surrender,
and the entire Surrender Value will be paid to the Contractholder. For a partial
surrender, any Surrender Charge will be in addition to the amount requested by
the Contractholder.
 
     A surrender will result in the cancellation of Units and the withdrawal of
amounts credited to the Guaranteed Interest Account, in accordance with the
directions of the Contractholder, with an aggregate value equal to the dollar
amount of the surrender plus, if applicable, the Annual Contract Charge and any
Surrender Charge. For a partial surrender, the Company will cancel Units of the
particular Subaccounts and withdraw amounts from the Guaranteed Interest Account
in accordance with the allocation specified by the Contractholder in written
notice to the Company at its Operations Center at the time the request for the
partial surrender is received; provided, however, that allocations by a
Contractholder against the Guaranteed Interest Account will be limited (the "GIA
Allocation Limitation") to that amount which bears the same proportion to the
total amount being surrendered as the amount credited to the Guaranteed Interest
Account of the Contractholder bears to the total of (i) all amounts credited to
the Guaranteed Interest Account of the Contractholder and (ii) the aggregate
value of Units held in all Subaccounts of the Contractholder, unless there is no
Cash Value in any Subaccount at the time the transfer request is received.
Allocations may be by either amount or percentage. Allocations by amount require
that at least $25 be allocated against the Guaranteed Interest Account or any
Subaccount designated by the Contractholder. If there is insufficient Cash Value
in the Contractholder's Guaranteed Interest Account or a Subaccount to provide
for the requested allocation against it, or if the GIA Allocation Limitation is
exceeded, or the request is incorrect, the request will not be accepted. If an
allocation is not requested, then the entire amount of the partial surrender
will be allocated against the Guaranteed Interest Account and each Subaccount in
the same proportion that the Contract's Cash Value held in the Guaranteed
Interest Account and each Subaccount bears to the Contract's Cash Value.
 
     Any Surrender Charge will be allocated against the Guaranteed Interest
Account and each Subaccount in the same proportion that the amount of a partial
surrender allocated against the Guaranteed Interest Account and each Subaccount
bears to the total amount of the partial surrender. In the event that an
 
                                       18
<PAGE>   23
 
allocation of the partial surrender is not made, or there is insufficient cash
value in the Guaranteed Interest Account or any Subaccount to provide for its
proportionate share of the Surrender Charge, then the entire Surrender Charge
will be allocated against the Guaranteed Interest Account and each Subaccount in
the same proportion that the Cash Value held in the Guaranteed Interest Account
and each Subaccount (after allocation of the partial surrender amount) bears to
the Contract's Cash Value.
 
     Any cash surrender amount will be paid within seven (7) days from the date
the election becomes effective, except as the Company may be permitted to
postpone such payment in accordance with the Investment Company Act of 1940.
Postponement is currently permissible only (1) for any period (a) during which
the New York Stock Exchange is closed other than customary weekend and holiday
closings, or (b) during which trading on the New York Stock Exchange is
restricted as determined by the Securities and Exchange Commission, (2) for any
period during which an emergency exists as a result of which (a) disposal of
securities held by the Funds is not reasonably practicable, or (b) it is not
reasonably practicable to determine the value of the net assets of the Funds, or
(3) for such other periods as the Securities and Exchange Commission may by
order permit for the protection of Contractholders. Any cash surrender involving
payment from amounts credited to the Guaranteed Interest Account may, to the
extent amounts are paid from the Guaranteed Interest Account, 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. The Contractholder may
elect to have the amount of a surrender settled under one of the Settlement
Options of the Contract. (See "Annuity Provisions" at page 24.)
 
     Since the Contracts offered by this Prospectus may be issued in connection
with retirement plans that meet the requirements of certain sections of the
Internal Revenue Code, reference should be made to the terms of the particular
retirement plan for any limitations or restrictions on cash surrenders.
 
     The tax consequences of a cash surrender should be carefully considered
(see "FEDERAL TAX STATUS" at page 30).
 
                                 DEATH BENEFIT
 
DEATH BENEFIT PROVIDED BY THE CONTRACT
 
     In the event of the death of the Annuitant (and the Contingent Annuitant,
if one has been named) (see "Contingent Annuitant" at page 27) prior to the
Annuity Commencement Date, the Company will pay a Death Benefit to the
Beneficiary. The amount of the Death Benefit will be the greater of (a) the Cash
Value on the date of the Annuitant's death, and (b) the Purchase Payments paid,
less any partial surrenders and their Surrender Charges. If the death of the
Annuitant occurs on or after the Annuity Commencement Date, no Death Benefit
will be payable except as may be provided under the Settlement Option elected.
 
ELECTION AND EFFECTIVE DATE OF ELECTION
 
     During the lifetime of the Annuitant and prior to the Annuity Commencement
Date, the Contractholder may elect to have the Death Benefit of the Contract
applied under one or more Settlement Options to effect an annuity for the
Beneficiary as payee after the death of the Annuitant. (See "Settlement Options"
at page 25.) 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 (a)
to receive the Death Benefit in the form of a cash payment; or (b) to have the
Death Benefit applied under one of the Settlement Options. (See "Settlement
Options" at page 25.) If an election by the payee is not received by the Company
within thirty (30) days following the date proceeds become payable, the payee
will be deemed to have elected a cash payment. Either election described above
may be made by filing with the Company a written election in such form as the
Company may require. Any proper election of a method of settlement of the Death
Benefit by the Contractholder will become effective on the date it is signed,
but any election will be subject to any payment made or action taken by the
Company before receipt of the notice at the Company's Operations Center.
 
                                       19
<PAGE>   24
 
     Reference should be made to 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 is
deemed to become effective and due proof of death is received, except as the
Company may be permitted to postpone such payment in accordance with the
Investment Company Act of 1940. 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. Interest at a rate
determined by the Company will be paid on any Death Benefit paid in one sum,
from the date of the Annuitant's (or Contingent Annuitant's, if applicable)
death to the date of payment. The interest rate will not be less than 2 3/4
percent annually.
 
                             CHARGES AND DEDUCTIONS
 
     Charges may be assessed under the Contracts as follows:
 
DEDUCTIONS FROM PAYMENTS
 
     A deduction may be made from each Purchase Payment for premium or similar
taxes prior to allocation of any Net Purchase Payment among the Subaccounts of
the Variable Account. Currently, the Company does not make such a deduction, but
may do so in the future. The Company will provide the Contractholder with
written notice of its intention to make deductions for premium or other taxes.
Any such deduction will apply only to Purchase Payments made after notice has
been sent by the Company. The amount of the deduction will vary from locality to
locality, but will generally range from 0 percent to 3.5 percent of Purchase
Payments. Residents of the Commonwealth of Pennsylvania should be aware that a
tax on Purchase Payments has been adopted; however, the Company currently is
assuming responsibility for payment of this tax. In the event that the Company
will begin to make deductions for such tax from future Purchase Payments, it
will give notice to each affected Contractholder.
 
CHARGES AGAINST CASH VALUE
 
     Surrender Charge.  The Contract imposes a contingent deferred sales charge,
called a "Surrender Charge," on full and partial surrenders and on the Annuity
Commencement Date. The Surrender Charge, which will never exceed 7 percent of
total Purchase Payments, 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 using
funds from its General Account, which may contain funds deducted from the
Variable Account to cover mortality and expense risks borne by the Company. (See
"Mortality and Expense Risk Charge" at page 23.)
 
     If all or a portion of the Contract's Surrender Value (see "Surrenders" at
page 18) is surrendered or if the Surrender Value is received at maturity on the
Annuity Commencement Date, a Surrender Charge will be calculated at the time of
surrender and will be deducted from the Cash Value. A Surrender Charge will not
be imposed against Cash Value surrendered in a Contract Year up to an amount
equal to Net Purchase Payments made by the Contractholder prior to the Contract
Year of the surrender and the preceding 7 Contract Years. In addition, the
Surrender Charge, which otherwise would have been deducted, will not be deducted
to the extent necessary to permit the Contractholder to obtain an amount equal
to the Guaranteed Free Surrender Amount (the "Guaranteed Free Surrender
Amount"). (See "Guaranteed Free Surrender Amount" at page 22.) No Surrender
Charge will be imposed if the surrender is a full surrender and the following
conditions are met: (i) the Annuitant is age 59 1/2 or older on the date of the
full surrender; (ii) the Contract has been in force for at least 10 Contract
Years; and (iii) one or more Purchase Payments were remitted during each of at
least 7 of the 10 Contract Years immediately preceding the date of surrender. In
addition, no Surrender Charge will be imposed if the Contract is surrendered
after the third Contract Year and the
 
                                       20
<PAGE>   25
 
surrender proceeds are paid under either Settlement Option 3 or Settlement
Option 3A (See "Settlement Options" at page 25). In no event will the aggregate
Surrender Charge exceed 7 percent of the total Purchase Payments made in the
Year of the surrender and during the 7 preceding Contract Years. The Contract
Date and Contract Years shall remain unchanged as a result of the Merger.
 
     For a partial surrender, the Surrender Charge will be deducted from any
remaining Contract Value, if sufficient; otherwise, it will be deducted from the
amount surrendered. Any Surrender Charge will be allocated against the
Guaranteed Interest Account and each Subaccount of the Variable Account in the
same proportion that the amount of the partial surrender allocated against the
Guaranteed Interest Account and each Subaccount bears to the total amount of the
partial surrender. But, if there is insufficient cash value in the Guaranteed
Interest Account or any Subaccount to provide for its proportionate share of the
charge, then the entire charge will be allocated against the Guaranteed Interest
Account and each Subaccount in the same proportion that the Cash Value held in
the Guaranteed Interest Account and each Subaccount bears to the cash value in
the Guaranteed Interest Account and all Subaccounts.
 
     No Surrender Charge will be deducted from Death Benefits. (See "Death
Benefit" at page 20.)
 
     For purposes of determining the Surrender Charge, surrenders will be
attributed to payments on a first-in, first-out basis. Contractholders should
note that this is different from the allocation method that is used for
determining tax obligations. (See "FEDERAL TAX STATUS" at page 30.)
 
     Amount of Surrender Charge.  The amount of the Surrender Charge is
determined as follows:
 
     Step 1.  Allocate Purchase Payments on a first-in, first-out basis to the
amount surrendered (any Purchase Payments previously allocated to calculate a
surrender charge are unavailable for allocation to calculate any future
surrender charges); and
 
     Step 2.  Multiply each such allocated Purchase Payment by the appropriate
surrender charge percentage determined on the basis of the table below:

     Step 3.  Add the products of each multiplication in Step 2 above.
 
     Guaranteed Free Surrender Amount.  The Surrender Charge may be reduced by
using the Guaranteed Free Surrender Amount provided for in the Contract. For
Non-Qualified Contracts (and Contracts issued for IRA and SEP-IRA) in certain
states which have granted approval, the Guaranteed Free Surrender Amount
provides that an amount up to 10% of the Contract's Cash Value (on the date the
first partial surrender request is received during a Contract Year) may be
surrendered without application of a surrender charge. For Qualified Contracts
issued on or after May 1, 1994 (other than Contracts issued for IRA and SEP-IRA)
in certain states which have granted approval, the Guaranteed Free Surrender
Amount provides that the greater of $10,000 (but not more than the Contract's
Cash Value) or 10% of the Contract's Cash Value (on the date the first partial
surrender request is received during a Contract Year) may be surrendered without
application
 
                                       21
<PAGE>   26
 
of surrender charge, provided no prior partial surrender was made during that
Contract year. (See a registered representative of MSC who is also a licensed
agent of the Company for which states have granted approval.) For holders of
Qualified Contracts issued before May 1, 1994 and for holders of Contracts in
those states where approval has not been granted, the Guaranteed Free Surrender
Amount provides that an amount up to 10% of the Contract's Cash Value (on the
date the partial surrender request is received) may be surrendered without the
application of a surrender charge, provided no prior partial surrender was made
during that Contract Year. The Company reserves the right to limit the number of
partial surrenders available under the Guaranteed Free Surrender Amount to 12
per Contract Year. Since Purchase Payments are allocated on a first-in,
first-out basis, the free surrender amount will not reduce surrender charges to
the extent that any Cash Value in that amount is equal to Purchase Payments
received 8 or more Contract Anniversaries ago.
 
     For illustrations of how the Surrender Charge is calculated, see Appendix A
on page A-1 of this Prospectus.
 
     Annual Contract Charge.  The Company has primary responsibility for the
administration of the Contract and the Variable Account. 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.
 
   
     An Annual Contract Charge will be deducted from the Contract's Cash Value
to help cover administrative expenses. Currently, for Non-Qualified Contracts
(and Contracts issued for IRA and SEP-IRA) the amount of the charge is $30, but
it may be increased to as much as $50 on 30 days' written notice to the
Contractholder. For Qualified Contracts (other than those issued for IRA and
SEP-IRA) currently the amount of the charge is reduced to $15, but it may be
increased to as much as $50 on 30 days written notice to the Contractholder, and
will be increased to $30 in the event that the Contract is no longer a Qualified
Contract. The charge will be deducted on (a) each Contract Anniversary prior to
the Annuity Commencement Date, (b) the Annuity Commencement Date, and (c) the
date of full surrender (if that date is not a Contract Anniversary). The amount
of the charge will be allocated against the Guaranteed Interest Account and each
Subaccount of the Variable Account in the same proportion that the Cash Value in
the Guaranteed Interest Account and each Subaccount bears to the Cash Value of
the Contract. The Company does not expect to make any profit from the
administrative cost deductions.
    
 
     Transfer Charge.  The Company has reserved the right to impose a transfer
charge, which will not exceed $25, for each transfer instructed by the
Contractholder among the Subaccounts or to or from the Guaranteed Interest
Account and one or more of the Subaccounts in excess of 4 transfers in a
Contract Year, to compensate the Company for the costs of effectuating the
transfer. Currently, the Company does not do so. The Company does not expect to
make a profit from the transfer charge. This charge will be deducted from the
Contract's Cash Value held in the Subaccount(s) from which the transfer is made,
or from the Guaranteed Interest Account if a transfer is made therefrom, and
will be allocated against these Subaccount(s) or the Guaranteed Interest Account
in the same proportion as the amounts transferred. If there is insufficient
value in a Subaccount or the Guaranteed Interest Account to provide for that
Subaccount's or the Guaranteed Interest Account's proportionate share of the
charge, then the entire charge will be allocated in the same manner as the
Annual Contract Charge. (See "Charges Against Cash Value -- Annual Contract
Charge" at page 22.)
 
MORTALITY AND EXPENSE RISK CHARGE
 
     A daily charge will be deducted from the value of the net assets of the
Variable Account to compensate the Company for mortality and expense risks
assumed in connection with the Contract. This daily charge from the Variable
Account will be at the rate of 0.003425 percent (equivalent to an annual rate of
1.25 percent) of the average daily net assets of the Variable Account. Of the
1.25 percent charge, .80 percent is for assuming mortality risks, and .45
percent is for assuming expense risks. The daily charge will be deducted from
the net
 
                                       22
<PAGE>   27
 
asset value of the Variable Account, and therefore the Subaccounts, on each
Valuation Date. These charges will not be deducted from the Guaranteed Interest
Account. Where the previous day (or days) was not a Valuation Date, the
deduction on the Valuation Date will be 0.003425 percent multiplied by the
number of days since the last Valuation Date.
 
     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, and that an aggregate amount of annuity benefits
greater than that projected will accordingly 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
percent 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. Should, however, the amount of the charge exceed the amount needed,
the excess will be retained by the Company in its general account. Should the
amount of the charge be inadequate, the Company will pay the difference out of
its General Account.
 
TAXES
 
     Currently, no charge will be made against the Variable Account for federal
income taxes. The Company may, however, make such a charge in the future if
income or gains within the Variable Account will incur any federal income tax
liability. Charges for other taxes, if any, attributable to the Variable Account
may also be made. (See "FEDERAL TAX STATUS" at page 30.)
 
INVESTMENT ADVISORY FEE
 
   
     Because the Variable Account purchases shares of the Funds, the net assets
of the Variable Account will reflect the investment advisory fee and other
expenses incurred by the Funds. MONY America, as investment adviser to the MONY
Series Fund, will receive monthly compensation with respect to the Intermediate
Term Bond, Long Term Bond, and Government Securities Portfolios that it advises
at an annual rate of 0.50 percent of the first $400 million of the aggregate
average daily net assets of each of those MONY Series Fund Portfolios, 0.35
percent of the next $400 million of the aggregate average daily net assets of
each of those MONY Series Fund Portfolios, and 0.30 percent of the aggregate
average daily net assets of each of those MONY Series Fund Portfolios in excess
of $800 million. MONY America, as investment adviser to the MONY Series Fund,
will receive monthly compensation with respect to the Money Market Portfolio
that it advises at an annual rate of 0.40 percent of the first $400 million of
the average daily net assets of the Money Market Portfolio; 0.35 percent of the
next $400 million of the average daily net assets of the Money Market Portfolio;
and 0.30 percent of the average daily net assets of the Money Market Portfolio
in excess of $800 million. Each daily charge for the fee is divided among those
Portfolios in proportion to their net assets on that date. Enterprise Capital,
as investment adviser to the Accumulation Trust, will receive from the
Accumulation Trust monthly compensation with respect to the Equity, Small Cap
and Managed Portfolios that it advises at an annual rate of 0.80 percent of the
first $400 million of the aggregate average daily net assets of those
portfolios, 0.75 percent of the next $400 million of the aggregate average daily
net assets of those portfolios, and 0.70 percent of the aggregate average daily
net assets of those portfolios which exceed $800 million. OpCap Advisors, a
subsidiary of Oppenheimer Capital, as sub-investment adviser to the Equity and
Managed Portfolios of the Accumulation Trust will receive from Enterprise
Capital and not the Accumulation Trust 0.40 percent (0.30 percent of assets in
excess of $1 billion) of the aggregate average daily net assets of the Equity,
and Managed Portfolios. GAMCO Investors, Inc. as sub-investment adviser to the
Small Cap Portfolio of the Accumulation Trust, will receive from Enterprise
Capital and not the Accumulation Trust, 0.40 percent (0.30 percent of assets in
excess of $1 billion) of the aggregate average daily net assets of the Small Cap
Portfolio. Enterprise Capital, as investment adviser to the Accumulation Trust,
will receive with respect to the High Yield Bond Portfolio monthly compensation
at an annual rate of 0.60 percent of the
    
 
                                       23
<PAGE>   28
 
aggregate average daily net assets of the High Yield Bond Portfolio, and
Caywood-Scholl Capital Corporation, as sub-investment adviser to the High Yield
Bond Portfolio, will receive from Enterprise Capital and not the Accumulation
Trust, .30 percent of the aggregate average daily net assets (.252 percent for
assets in excess of $100 million) of the High Yield Bond Portfolio. Enterprise
Capital, as investment adviser to the Accumulation Trust will receive with
respect to the International Growth Portfolio monthly compensation at an annual
rate of .85 percent of the aggregate average daily net assets of the
International Growth Portfolio, and Brinson Partners, as sub-investment adviser
to the International Growth Portfolio, will receive from Enterprise Capital and
not the Accumulation Trust, .4495 percent (53% of the fee received by Enterprise
Capital; the fee paid to Brinson Partners declines as assets exceed $100
million) of the aggregate average daily net assets of the International Growth
Portfolio. The investment advisers will reimburse the Funds for the amount, if
any, by which the aggregate ordinary operating expenses of any of these
Portfolios incurred by the Funds in any calendar year exceed the most
restrictive expense limitations then in effect under any state securities law or
regulation. Currently, the most restrictive expense limitation in effect limits
expenses of each Fund Portfolio to an amount equal to 2.5 percent of the first
$30 million of average daily net assets of the Portfolio, 2.0 percent of the
next $70 million, and 1.5 percent of the average daily net assets of the
Portfolio in excess of $100 million.
 
                               ANNUITY PROVISIONS
 
ANNUITY COMMENCEMENT DATE
 
   
     Annuity payments under a Contract will begin on the Annuity Commencement
Date that is selected by the Contractholder at the time the Contract is applied
for. The Annuity Commencement Date chosen may be no earlier than the Contract
Anniversary nearest the Annuitant's 10th birthday, and no later than the
Contract Anniversary nearest the Annuitant's 90th (85th for Contracts issued
before October 24, 1997) birthday. The minimum number of years from the Contract
Date to the Annuity Commencement Date is 10. The Annuity Commencement Date may
be advanced to a date not earlier than the 10th Contract Anniversary or deferred
from time to time by the Contractholder by written notice to the Company,
provided that (1) notice of such deferral or advance is received by the Company
prior to the then current Annuity Commencement Date, and (2) the new Annuity
Commencement Date is a date which is not later than the Contract Anniversary
nearest the Annuitant's 90th (85th for Contracts issued before October 24, 1997)
birthday. A particular retirement plan may contain other restrictions.
    
 
     On the Annuity Commencement Date, the Contract's Surrender Value will be
applied to provide an annuity or any other option previously chosen by the
Contractholder and permitted by the Company. A supplementary contract will be
issued, and that contract will set forth the terms of the settlement. No
payments may be requested under the Contract's surrender provisions after the
Annuity Commencement Date, and 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 the Annuity Commencement Date.
 
ELECTION AND CHANGE OF SETTLEMENT OPTION
 
     During the lifetime of the Annuitant and prior to the Annuity Commencement
Date, the Contractholder may elect one or more of the Settlement Options
described below, or such other settlement option (including a lump-sum payment)
as may be agreed to by the Company. The Contractholder may also change any
election, but written notice of an election or change of election must be
received by the Company at its Operations Center prior to the Annuity
Commencement Date. If no election is in effect on the Annuity Commencement Date,
Settlement Option 3, for a Life Annuity with 10 years certain, based on the
Annuitant's life, will be deemed to have been elected.
 
     Settlement Options may also be elected by the Contractholder or the
Beneficiary as provided in the Death Benefit and Surrender sections of this
Prospectus. (See "DEATH BENEFIT" at page 20 and "SURRENDERS" at page 18.)
 
                                       24
<PAGE>   29
 
     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.
 
     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 3/4
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 above.
 
     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 1/2 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 deem the election to have been made of the longest period
certain.
 
     In Qualified Plans, settlement options available to Contractholders may be
restricted by the terms of the plans.
 
FREQUENCY OF ANNUITY PAYMENTS
 
     Annuity payments will be paid as monthly installments unless the payee
requests quarterly, semiannual, or annual installments at the time the option is
chosen. However, if the net amount available to apply under any Settlement
Option under any circumstances is less than $1,000, the Company shall have 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 payments to such intervals as will result in payments of at least
$25.
 
ADDITIONAL PROVISIONS
 
     The Company may require proof of age of the Annuitant before making any
life annuity payment provided for by the Contract. If the age of the Annuitant
has been misstated, the amount payable will be the amount that the amount
settled would have provided at the correct age. Once life income payments have
 
                                       25
<PAGE>   30
 
begun, 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, due 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 may 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 applicable to Contracts
purchased under an employment-related insurance or benefit 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 and those plans where an employer
believes that the Norris decision applies.
 
     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 be applicable, on any employment-related plan for which a
Contract may be purchased.
 
                                OTHER PROVISIONS
 
OWNERSHIP
 
     The Contractholder has all rights and may receive all benefits under the
Contract. During the lifetime of the Annuitant (and the Contingent Annuitant if
one has been named), the Contractholder shall be the person so designated in the
application, unless changed, or unless a Successor Contractholder becomes the
Contractholder. On and after the death of the Annuitant (and the Contingent
Annuitant, if applicable), the Beneficiary shall be the Contractholder.
 
     The Contractholder may name a Successor Contractholder or a new
Contractholder at any time. If the Contractholder dies, the Successor
Contractholder, if living, becomes the Contractholder. 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
Contractholder or Successor Contractholder will not apply to any payment made or
action taken by the Company prior to the time a request for change is received.
Contractholders should consult a competent tax advisor prior to changing
Contractholders.
 
PROVISION REQUIRED BY SECTION 72(S) OF THE CODE
 
     If the Contractholder of a Non-Qualified Plan dies before the Annuity
Commencement Date and while the Annuitant is living, and if that
Contractholder's spouse is not the Successor Contractholder as of the date of
that Contractholder's death (as evidenced by proof satisfactory to the Company),
then the Contract will be surrendered as of the date of that death. If the
Successor Contractholder is the Beneficiary, the surrender proceeds may, at the
option of the Successor Contractholder, be paid over the life of the Successor
Contractholder. Such payments must begin no later than one year after such date
of death. If the Successor Contractholder is a surviving spouse, then the
surviving spouse will be treated as the new Contractholder of the Contract.
Under such circumstances, it shall not be necessary to surrender the Contract.
If the spouse is not the Successor Contractholder 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 Contractholder, 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.
 
                                       26
<PAGE>   31
 
     Further, if the Contractholder dies on or after the Annuity Commencement
Date, 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
Contractholder'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 Contractholder or his/her Designated Beneficiary either by
or beginning not later than April 1 of the calendar year following the calendar
year in which such Participant attains age 70 1/2. The period over which such
distribution will be made is the life of such Participant or the lives of such
Participant and Designated Beneficiary.
 
     Where distributions have begun in accordance with the previous paragraph
and the Participant dies before Contractholder'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. If the Participant dies before the
commencement of such distributions and there is no Designated Beneficiary, the
Contract will be surrendered as of the date of death. 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 forego distribution and treat the IRA as his/her
own Plan.
 
     Qualified Plan Contracts include those qualifying for special treatment
under Sections 401, 403, and 408 of the Code.
 
     It is the Contractholder's responsibility to assure that distribution rules
imposed by the Code will be met.
 
CONTINGENT ANNUITANT
 
   
     Except where the Contract is issued in connection with a Qualified Plan, a
Contingent Annuitant may be designated by the Contractholder. 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 Operations Center. The Contingent Annuitant may be deleted by written
notice to the Company at its Operations Center. A designation or deletion of a
Contingent 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 before receipt of the notice at the Company's
Operations Center. The Contingent Annuitant will be deleted from the Contract
automatically by the Company as of the Contract Anniversary nearest the
Contingent Annuitant's 90th (85th for Contracts issued before October 24, 1997)
birthday.
    
 
     On the death of the Annuitant, the Contingent 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 Contingent Annuitant is living on the date of the Annuitant's
     death;
 
          (3) if the Annuitant was the Contractholder on the date of death, the
     Successor Contractholder must have been the Annuitant's spouse; and
 
   
          (4) if the Annuity Commencement Date is later than the Contract
     Anniversary nearest the Contingent Annuitant's 90th (85th for Contracts
     issued before October 24, 1997) birthday, the Annuity Commencement Date
     will be automatically advanced to that Contract Anniversary.
    
 
                                       27
<PAGE>   32
 
EFFECT OF CONTINGENT ANNUITANT'S BECOMING THE ANNUITANT
 
     If the Contingent Annuitant becomes the Annuitant at the death of the
Annuitant, in accordance with the conditions specified above, the Death Benefit
proceeds of the Contract will be paid to the Beneficiary only on the death of
the Contingent Annuitant. If the Contingent Annuitant was the Beneficiary on the
Annuitant's death, the Beneficiary will be changed automatically to the person
who was the Successor Beneficiary on the date of death. If there was no
Successor Beneficiary, then the Contingent Annuitant's executors or
administrators, unless the Contractholder directed otherwise, will become the
Beneficiary. All other rights and benefits under the Contract will continue in
effect during the lifetime of the Contingent Annuitant as if the Contingent
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 Home Office. The Company is not
responsible for assessing the validity or effect of any assignment. The Company
shall not be liable as to any payment or other settlement made by the Company
before receipt of the assignment.
 
     If the Contract is issued pursuant to 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 Contractholder should
consult a competent tax advisor before assigning the Contract.
 
CHANGE OF BENEFICIARY
 
     So long as the Contract is in force, the Beneficiary or Successor
Beneficiary may be changed by written request to the Company at its Operations
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 Operations Center.
 
SUBSTITUTION OF SECURITIES
 
     If the shares of any Portfolio of the Funds should no longer be available
for investment by the Variable Account or, if in the judgment of the Company's
Board of Trustees, further investment in shares of one or more of the Portfolios
of the Funds should become inappropriate in view of the purposes of the
Contract, the Company may substitute shares of another mutual fund for shares of
the Funds already purchased or to be purchased in the future by Purchase
Payments under 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 Contractholder, the Contract may be modified by the
Company, but only if such modification (1) is necessary to make the Contract or
the Variable Account 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 (3) is
necessary to reflect a change in the operation of the Variable Account 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.
 
                                       28
<PAGE>   33
 
CHANGE IN OPERATION OF VARIABLE ACCOUNTS
 
     At the Company's election and subject to any necessary vote by persons
having the right to give instructions with respect to the voting of shares of
the Funds held by the Subaccounts, the Variable Account may be operated as a
management company under the Investment Company Act of 1940 or it may be
deregistered under the Investment Company Act of 1940 in the event registration
is no longer required. Deregistration of the Variable Account requires an order
by the Securities and Exchange Commission. In the event of any change in the
operation of the Variable Account pursuant to 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 the Variable Account will be
invested in shares of the corresponding Portfolios of the Funds. The Company is
the legal holder of those shares and as such has the right to vote to elect the
Board of Directors of MONY Series Fund and the Board of Trustees of the
Accumulation Trust, to vote upon certain matters that are required by the 1940
Act to be approved or ratified by the shareholders of a mutual fund, and to vote
upon any other matter that may be voted upon at a shareholder's meeting. To the
extent required by law, the Company will vote the shares of each of the Funds
held in the Variable Account (whether or not attributable to Contractholders) at
shareholder meetings of each of the Funds in accordance with the instructions
received from Contractholders. The number of votes will be determined as of the
record date selected by the Board of Directors or Board of Trustees of the
respective Fund. The Company will furnish Contractholders 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, or to 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 changes in the investment objectives or policies of any
Portfolio or in an investment adviser or principal underwriter for either or
both of the Funds, if the Company reasonably disapproves those changes in
accordance with applicable federal regulations. If the Company does disregard
voting instructions, it will advise Contractholders of that action and its
reasons for the action in the next semiannual report to Contractholders.
 
     Each Contractholder will have the equivalent of one vote per $100 of value
attributable to the Contract held in each Subaccount of the Variable Account,
with fractional votes for amounts less than $100. For voting purposes, this
value attributable to the Contract is equal to the Cash Value. These votes,
represented as votes per $100 of value in each Subaccount of the Variable
Account, are converted into a proportionate number of votes in shares of the
corresponding Portfolio of each of the Funds. Shares of each of the Funds held
in each Subaccount for which no timely instructions from Contractholders are
received 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 shares of the corresponding Portfolio of one of the Funds in
a Subaccount for which instructions may be given by a Contractholder is
determined by dividing the portion of the value attributable to the Contract
held in that Subaccount by the net asset value of one share in the corresponding
Portfolio of the respective Fund. In other words, if the value attributable to
the Contract held in the Subaccount were $540 and the net asset value of the
respective Fund's shares of the Portfolio held in that Subaccount were $20 per
share on the record date, then the Contractholder could issue instructions on
5.4 votes (representing votes per $100 of value attributable to the Contract
held in the Subaccount), which would be converted into instructions on 27 shares
of the respective Fund.
 
                                       29
<PAGE>   34
 
     Matters on which Contractholders may give voting instructions include the
following: (1) approval of any change in the Investment Advisory Agreement and
Services Agreement for the Portfolio(s) of the Fund corresponding to the
Contractholder's selected Subaccount(s); (2) any change in the fundamental
investment policies of the Portfolio(s) corresponding to the Contractholder's
selected Subaccount(s); and (3) any other matter requiring a vote of the
shareholders of either of the Funds. With respect to approval of the Investment
Advisory Agreement or any change in a Portfolio's fundamental investment
policies, Contractholders participating in that Portfolio will vote separately
on the matter pursuant to the requirements of Rule 18f-2 under the 1940 Act.
 
                         DISTRIBUTION OF THE CONTRACTS
 
     MONY Securities Corp. ("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
registered as a 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 also
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 percent of Purchase Payments. Additional compensation may be paid
for other services not directly related to the sale of the Contract. Such
services include the training of personnel and the production of promotional
literature.
 
                               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 Section 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
Cash Value, on annuity payments, and on the economic benefit to the
Contractholder, the Annuitant, and the Beneficiary may depend upon the type of
retirement plan for which the Contract is purchased and upon the tax and
employment status of the individual concerned.
    
 
     The following discussion of the treatment of the Contracts and of the
Company under the federal income tax laws is general in nature, is based upon
the Company's understanding of current federal income tax laws, and is not
intended as tax advice. Any person contemplating 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 the Variable
Accounts, 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 Contractholder 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, except to the extent
of employee (in the case of Qualified Plans) or Contractholder (in the
 
                                       30
<PAGE>   35
 
case of Non-Qualified Plans) contributions, are generally taxable to the
annuitant as ordinary income. Contractholders, 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 Contractholder 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.
 
     Under the Technical and Miscellaneous Revenue Act of 1988 ("TAMRA"), for
purposes of determining the amount includible in gross income with respect to
distributions not received as an annuity, including deemed distributions
resulting from gratuitous transfers, all annuity contracts issued by the same
company to the same Contractholder during any 12 month period, other than those
issued to qualified retirement plans, will be treated as one annuity contract.
The IRS is given power to prescribe rules to prevent avoidance of this rule
through special purchases of contracts or otherwise. None of these rules is
expected to affect taxbenefitted 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, 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.
 
ANNUITY CONTRACTS GOVERNED BY SECTION 403(B) OF THE CODE
 
     An annuity contract will not be treated as a Qualified Contract under
Section 403(b) of the Code unless distributions which are attributable to a
contribution made pursuant to a salary reduction agreement may be paid only: (1)
when the Contractholder attains age 59 1/2; (2) when the Contractholder
separates from the service of his employer; (3) when the Contractholder dies;
(4) when the Contractholder becomes permanently disabled within the meaning of
Section 72(m) of the Code; or (5) in the case of hardship. These restrictions
generally apply to contributions made after December 31, 1988 and to any
increase in Cash Value of the Contract after December 31, 1988. Therefore
effective January 1, 1989 and thereafter, any contributions made, or increase in
Cash Value, on or after January 1, 1989 will be restricted from withdrawal
except upon attainment of age 59 1/2, separation from service, death, disability
or hardship (hardship withdrawals are to be limited to the amount of the
Contractholder's Purchase Payments). However, any Purchase Payments that reflect
employer contributions and the earnings thereon will not be restricted unless
specifically provided for by the applicable employer's plan.
 
   
     Effective January 1, 1989, the Contracts offered by this Prospectus have
been withdrawn from sale in connection with Qualified Plans which intend to
qualify for federal income tax advantages available under Section 403(b) of the
Code.

RETIREMENT PLANS
 
     The Contracts described in this Prospectus 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 Sections 219 and
     408(b) of the Code, including Simplified Employee Pensions established by
     employers pursuant to Section 408(k);
 
          (3) Tax-Sheltered Annuity Plans established by certain educational and
     tax-exempt organizations under Section 403(b) of the Code (effective
     January 1, 1989, the Contracts offered by this Prospectus have been
     withdrawn from sale in all states in connection with Qualified Plans which
     intend to qualify for federal income tax advantages available under Section
     403(b) of the Code);
 
          (4) Deferred compensation plans provided by certain governmental
     entities under Section 457 of the Code; and
 
          (5) 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 herein 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 Contractholders, 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
 
     From time to time the performance of one or more of the Subaccounts may be
advertised. The performance data contained in these advertisements is based upon
historical earnings and is not indicative of future performance. The data for
each Subaccount reflects the results of the corresponding 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 "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 Contractholder
 
                                       32
<PAGE>   37
 
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 the Variable Account,
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.
 
     Returns for periods exceeding one year reflect the average annual total
return for such period. 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. 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 purchase 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.
 
     In addition, reference in advertisements may be made to various indices,
including without limitation, the Standard & Poor's 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 in order
to provide the reader a basis for comparison.

                               LEGAL PROCEEDINGS
 
     There are no legal proceedings to which the Variable Account or the
principal underwriter is a party. The Company is engaged in various kinds of
routine litigation which, in the opinion of the Company, are not of material
importance in relation to the total capital and surplus of the Company.
 
                              FINANCIAL STATEMENTS
 
     The financial statements for the Company, included in the Statement of
Additional Information should be considered only as bearing on the ability of

statements of the Company should not be considered as bearing on the investment
performance of the assets held in the Variable Account. The financial statements

Additional Information.

                        CALCULATION OF SURRENDER CHARGE
 
ILLUSTRATION 1
 
     Suppose an initial Purchase Payment of $15,000 is the only payment made,
and no taxes are deducted from this payment. At the beginning of the third
Contract Year, the Cash Value of the Contract has grown to $18,000 and the
Contractholder requests a partial surrender of $2,000.
 
     The Surrender Charge is determined as follows:
 
     Step 1:  Purchase Payments are allocated to the surrender amount, as
follows:

  RECEIVED BY US        PAYMENT RECEIVED     TO SURRENDER     FUTURE SURRENDER

</TABLE>
 
     If the Contract is a Non-Qualified Contract --
 
     Step 2:  The Guaranteed Free Surrender Amount is calculated as 10% of the
Cash Value ($1,800). Reduce the resulting amount allocated to surrender ($2,000)
by the Guaranteed Free Surrender Amount ($1,800), and apply the Surrender Charge
Percentages as follows:

       1..........             2                   0              7               0
       2..........             1                 200              6              12
</TABLE>
 
     Step 3:  Summing the resulting Amounts of Surrender Charge produces a total
Surrender Charge of $12.
 
     The Surrender Charge, plus the amount of the surrender is then deducted
from the remaining Cash Value of the Non-Qualified Contract, for a total
withdrawal of $2,012.
 
     If the Contract is a Qualified Contract--
 
     Step 2:  The Guaranteed Free Surrender Amount is calculated as up to the
greater of 10% of the Cash Value ($1,800) of the Qualified Contract or up to
$10,000. Since the partial surrender requested is less than $10,000 (although it
is greater than 10 percent), there is no Surrender Charge.
 
     Since there is no Surrender Charge, the entire amount requested is
available under the Guaranteed Free Surrender Amount provision of the Qualified
Contract.
 
   
     Assuming that in the middle of the tenth Contract Year, a full surrender is
requested. The Cash Value at the time of full surrender is $28,000. Since this
is a full surrender, the Annual Contract Charge (currently $30) is deducted from
the Cash Value, leaving a remaining Cash Value balance of $27,970. For this
calculation, there is $13,000 of Purchase Payments made in the first Contract
Year.

     Step 3:  Summing the resulting Amounts of Surrender Charge produces a total
Surrender Charge of $0.
 
     Since there are no Purchase Payments such that 7 or less policy
anniversaries had passed since they were received, no part of the surrender
proceeds are subject to a Surrender Charge. Hence, no Surrender Charge is
assessed on this full surrender.
 
ILLUSTRATION 2
 
     Suppose Purchase Payments of $2,000 are made at the beginning of every
Contract Year. No taxes are deducted from these Payments. In the middle of the
third Contract Year, a partial surrender of $500 is requested. Suppose the Cash
Value has grown to $7,000 at the time of the partial surrender request.
 
     The Surrender Charge is determined as follows:
 
     Step 1:  Purchase Payments are allocated to the surrender amount, as

     Step 3:  Summing the resulting Amounts of Surrender Charge produces a total
Surrender Charge of $0.
 
     The partial surrender will be allocated to $500 of payments made in the
first Contract Year. But since 10 percent of the Cash Value ($700) of the
Non-Qualified Contract could be surrendered under the Guaranteed Free Surrender
Amount Provision, the partial surrender of $500 could be withdrawn without a
surrender charge.
 
     If the Contract is a Qualified Contract --
 
     Step 2:  The Guaranteed Free Surrender Amount is calculated as up to the
greater of 10% of the Cash Value ($700) of the Qualified Contract or up to
$10,000. Since the partial surrender requested is less than $10,000 and less
than 10% there is no surrender charge.
 
     Since there is no Surrender Charge, the entire amount requested is
available under the Guaranteed Free Surrender Amount provision of the Qualified
Contract.
 
     Assume that Purchase Payments of $2,000 have continually been made at the
beginning of each Contract Year, and that in the middle of the tenth Contract
Year, a partial surrender of $7,500 is requested. The Cash Value is $32,600 at
the time of the partial surrender request.
 
     The Surrender Charge is determined as follows:

Cash Value ($3,260) of the Non-Qualified Contract. Reduce the resulting amount
allocated to surrender ($3,500) in Contract Years 1 and 2 by the Guaranteed Free
Surrender Amount ($3,260), and apply the Surrender Charge Percentages as
follows:

     Step 3:  Summing the resulting Amounts of Surrender Charge produces a total
Surrender Charge of $100.
 
   
     The Surrender Charge, plus the amount of the surrender is then deducted
from the remaining Cash Value of the Non-Qualified Contract, for a total
withdrawal of $7,600.

     If the Contract is a Qualified Contract --
 
     Step 2:  The Guaranteed Free Surrender Amount is calculated as up to the
greater of 10% of the Cash Value ($3,260) of the Qualified Contract or up to
$10,000. Since the partial surrender requested is less than $10,000 (although it
is greater than 10 percent), there is no surrender charge.
 
     Since there is no Surrender Charge, the entire amount requested is
available under the Guaranteed Free Surrender Amount provision of the Qualified
Contract.
 
     Assuming that in the middle of the twelfth Contract Year, a full surrender
with the full proceeds being settled under Settlement Option 3, Single Life
Income for 10 years certain and during the balance of the annuitant's lifetime,
payments of $2,000 have continuously been made at the beginning of each contract
year. The Cash Value at the time of the full surrender is $26,000. Since this
example assumes a full surrender is being made, the Annual Contract Charge
(currently $30) is deducted from the Cash Value, leaving a remaining Cash Value
of $25,970.
 
   
     Since the full proceeds are being applied to Settlement Option 3, the
Surrender Charge is $0. The entire remaining Cash Value of $25,970 is applied to
the settlement option.

                               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>   47
 
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>   48
 
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, 1997, the yield was 4.07% and
the effective yield was 4.15%.
    
 
     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 prior to the Contract Year of surrender and the
preceding 7 Contract Years.

    Although MONY Variable Account A commenced operations in February 1991, the
total returns shown above reflect those operations as well as the historical
results for MONY Legacy Variable Account A. MONY Legacy Variable Account A
commenced operations on December 30, 1987 and the assets, reserves, and other
liabilities thereof became the assets, reserves, and other liabilities of the
MONY Variable Account A on February 28, 1991, the effective date of the merger
of MONY Legacy Life Insurance Company into the Company. Total return for the
period since inception reflects the average annual total return since the
inception (commencement of operations) of the corresponding portfolio of the
respective Fund, which is August 1988 for the Equity and Managed Portfolios,
September 1988 for the Small Cap Portfolio, March 1985 for the Intermediate Term
Bond and the Long Term Bond Portfolios, May 1991 for the Government Securities
Portfolio, and November 1994 for the International Growth and for the High Yield
Bond Portfolios. 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
shown in the table reflect the historical rates of return, deductions for all
charges, expenses, and fees of both the Funds (including the Investment Advisory
Fees described in the Prospectus (see "Investment Advisory Fee" at page 23) and
the Variable Account which would be imposed on the payment assumed, including a
contingent deferred sales (Surrender) charge imposed as a result of the full
surrender and a deduction for the Annual Contract Charge imposed on each
Contract Anniversary and upon full surrender and allocated to each Subaccount in
the proportion that the total value of that Subaccount bore to the total value
of the Variable Account at the end of the period indicated.

</TABLE>
    
 
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.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
   
To the Board of Trustees of
    
Mutual Life Insurance Company of New York and the
Contractholders of MONY Variable Account A:
 
   
     We have audited the accompanying statements of assets and liabilities of
MONY Variable Account A (comprising, respectively, the MONY Series Fund, Inc.'s
Equity Growth, Equity Income, Intermediate Term Bond, Long Term Bond,
Diversified, Government Securities and Money Market Subaccounts; the Enterprise
Accumulation Trust's Equity, Small Cap, Managed, International Growth and High
Yield Bond Subaccounts; and the OCC Accumulation Trust's Money Market, Bond,
Equity, Small Cap and Managed Subaccounts) as of December 31, 1997, the related
statements of operations for the year then ended and the statements of changes
in net assets for each of the two years in the period then ended. These
financial statements are the responsibility of MONY's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
    
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. Our procedures included
confirmation of securities owned as of December 31, 1997, by correspondence with
the custodian. An audit also includes assessing the accounting principles used
and significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of each of the respective
subaccounts constituting MONY Variable Account A as of December 31, 1997, the
results of their operations for the year then ended, and the changes in their
net assets for each of the two years in the period then ended, in conformity
with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
1. ORGANIZATION AND BUSINESS
 
     MONY Variable Account A (the "Variable Account") is a separate investment
account established on November 28, 1990 by The Mutual Life Insurance Company of
New York ("MONY"), under the laws of the State of New York.
 
     The Variable Account operates as a unit investment trust under the
Investment Company Act of 1940 (the "1940 Act"). The Variable Account holds
assets that are segregated from all of MONY's other assets and, at present, is
used only to support Flexible Payment Variable Annuity policies. These policies
are issued by MONY.
 
     There are currently seventeen subaccounts within the Variable Account, each
invests only in a corresponding portfolio of the MONY Series Fund, Inc.
("Fund"), Enterprise Accumulation Trust ("Enterprise") or the OCC Accumulation
Trust ("OCC") (formerly the Quest for Value Accumulation Trust) collectively,
the "Funds". The Funds are registered under the 1940 Act as open end,
diversified, management investment companies.
 
   
     On March 31, 1997, the Variable Account effected a substitution by
redeeming shares of the OCC Accumulation Trust Bond Portfolio and using the
redemption proceeds to purchase shares of the OCC Accumulation Trust U.S.
Government Income Portfolio. The substitution was effected through a redemption
of assets in-kind for the Variable Account and OCC.
    
 
   
     A full presentation of the related financial statements and footnotes of
the Fund, Enterprise and OCC are contained on pages 68 to 102; 105 to 142; and
145 to 166; respectively, and should be read in conjunction with these financial
statements.
    
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
  Investments:
 
     The investment in shares of each of the respective portfolios is stated at
the net asset values of each portfolio. Except for the Money Market Portfolio,
net asset values are based upon market quotations of the securities held in each
of the corresponding portfolios of the Funds. For the Money Market Portfolio,
the net asset values are based on the amortized cost of the securities held
which approximates value.
 
  Taxes:
 
     MONY is currently taxed as a life insurance company and will include the
Variable Account's operations in its tax return. MONY does not expect, based
upon current tax law, to incur any income tax burden upon the earnings or
realized capital gains attributable to the Variable Account. Based on this
expectation, no charges are currently being deducted from the the Variable
Account for federal income tax purposes.
 
3. RELATED PARTY TRANSACTIONS
 
     MONY is the legal owner of the assets held by the Variable Account.
 
     Purchase payments received from MONY by the Variable Account represent
gross purchase payments recorded by MONY less deductions retained for any
premium taxes.
 
     A periodic deduction is made from the cash value of the contract for the
annual contract charge. The deduction is for the expenses of administration and
is treated by the Variable Account as a contractholder redemption. The amount
deducted for all subaccounts for 1997 was $244,101.

3. RELATED PARTY TRANSACTIONS (CONTINUED)
     MONY receives from the Variable Account the amounts deducted for mortality
and expense risks at an annual rate of 1.25 percent of aggregate average daily
net assets. As MONY America, a wholly-owned subsidiary of MONY, acts as
investment adviser to the Fund, it receives amounts paid by the Fund for those
services.

acts as investment adviser to Enterprise, and it receives amounts paid by

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
TO THE BOARD OF TRUSTEES OF
THE MUTUAL LIFE INSURANCE COMPANY OF NEW YORK:
 
     We have audited the accompanying statutory statements of admitted assets,
liabilities, and surplus of The Mutual Life Insurance Company of New York ("the
Company") as of December 31, 1997 and 1996, and the related statutory statements
of operations, surplus, and cash flows for the years then ended. These statutory
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     The Company presents its financial statements in conformity with the
accounting practices prescribed or permitted by the Insurance Department of the
State of New York ("statutory"), which is a comprehensive basis of accounting
other than generally accepted accounting principles ("GAAP"). As explained in
Note 3, the accounting practices used by the Company vary from generally
accepted accounting principles, and the effects of these variances are material.
 
     In our opinion, because of the effects of the matter discussed in the
preceding paragraph, the statutory financial statements referred to above do not
present fairly, in conformity with GAAP, the financial position of the Company
as of December 31, 1997 and 1996, or the results of its operations and its cash
flows for the years then ended.
 
     In our opinion, however, the statutory financial statements referred to
above present fairly, in all material respects, the admitted assets,
liabilities, and surplus of the Company as of December 31, 1997 and 1996, and
the results of its operations and its cash flows for the years then ended on the
basis of accounting described in Note 3.
 
     Our audits were conducted for the purpose of expressing an opinion on the
financial statements taken as a whole. The Supplemental Schedule of Selected
Financial Data is presented to comply with the National Association of Insurance
Commissioners' Annual Statement Instructions and is not a required part of the
basic financial statements. The Supplemental Schedule of Selected Financial Data
has been subjected to the auditing procedures applied in the audits of the basic
financial statements and, in our opinion, is fairly stated, in all material
respects, in relation to the basic financial statements taken as a whole.

                 THE MUTUAL LIFE INSURANCE COMPANY OF NEW YORK
 
                         NOTES TO FINANCIAL STATEMENTS
 
1.  ORGANIZATION:
 
     The Mutual Life Insurance Company of New York, ("MONY" or the "Company") is
a New York domiciled mutual life insurance company primarily engaged in the
business of providing a wide range of life insurance, annuity, and investment
products to higher income individuals, particularly family builders,
pre-retirees and small business owners. The Company distributes its products to
such individuals primarily through its career agency sales force. These products
are sold throughout the United States and Puerto Rico.
 
2.  DEMUTUALIZATION AND INVESTMENT AGREEMENT:
 
     On September 8, 1997, the Company announced that it is pursuing converting
to a stock life insurance company through demutualization. In connection with
the demutualization, the Company has prepared a Plan of Reorganization ("the
Plan") which is subject to approval by the Insurance Department of the State of
New York as well as adoption by the Company's Board of Trustees and approval by
the policyholders.
 
     In connection with the Plan, among other things, the following will occur:
(i) the Company will convert from a New York mutual life insurance company to a
New York stock life insurance company (the "Plan of Demutualization") and become
a wholly owned subsidiary of MONY Financial Services Corporation (the "Holding
Company"), a holding company organized in Delaware for the purpose of becoming
the parent holding company of the Company, (ii) eligible policyholders of the
Company, as defined in the Plan, will receive shares of common stock of the
Holding Company, cash or policy credits, (iii) a closed block of certain
individual participating policies in classes for which the Company had a
dividend scale payable in 1998 (the "Closed Block") will be created on the Plan
effective date (the "Effective Date") and assets will be allocated to the Closed
Block to support the payment of benefits, dividends (as appropriate, based on
experience), and certain expenses and taxes relating to the policies included
therein, and (iv) shares of common stock of the Holding Company will be
registered under the Securities and Exchange Act of 1933 and offered to the
public in an initial public offering, if market conditions are appropriate.
 
     In connection with the transactions contemplated under the Plan described
above, on December 30, 1997, investment funds affiliated with Goldman, Sachs &
Co. consisting of GS Mezzanine Partners, L.P., G.S. Mezzanine Partners Offshore,
L.P., Stone Street Fund 1997, and Bridge Street Fund 1997, L.P. (collectively,
"the Investors"), entered into an investment agreement with the Company and the
Holding Company (the "Investment Agreement"), pursuant to which: (i) the
Investors purchased, for $115.0 million ("the Consideration"), Surplus Notes
issued by the Company (the "MONY Notes") with an aggregate principal amount
equal to the Consideration (see Note 15), and (ii) the Investors purchased, for
$10.0 million, warrants to purchase from the Holding Company at the Effective
Date (after giving effect to the initial public offering) in the aggregate of
7.0 percent of the fully diluted common stock of the Holding Company upon
certain terms and conditions and at a specified exercise price which is subject
to anti-dilution adjustments, as more specifically defined in the Investment
Agreement.
 
     In addition, under the terms of the Investment Agreement, the Investors
agreed, upon the Company's request, made at any time up to 90 days after the
Effective Date, to purchase an aggregate of 1.0 million shares of convertible
preferred stock of the Holding Company for a total purchase price of $100.0
million. The convertible preferred stock would be convertible at the option of
the holder at any time into common stock of the Holding Company at a conversion
price equal to the initial exercise price of the warrants and would be subject
to certain anti-dilution adjustments.
 
3.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
     The accompanying statutory financial statements have been prepared in
conformity with accounting practices prescribed or permitted by the Insurance
Department of the State of New York ("statutory"), which is a comprehensive
basis of accounting other than generally accepted accounting principles
("GAAP").

                 THE MUTUAL LIFE INSURANCE COMPANY OF NEW YORK
 
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
3.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED):
     The preparation of statutory financial statements requires management to
make estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of results of operations and
changes in surplus during the reporting period. Actual results could differ
significantly from those estimates. The most significant estimates made in
conjunction with the preparation of the Company's financial statements include
those used in determining (i) valuation reserves for mortgage loans and real
estate investments, and (ii) the liability for future policy benefits.
 
     In financial statements prepared in conformity with statutory accounting,
the accounting treatment of certain items is different than for financial
statements prepared in conformity with GAAP. Some of the general differences
include:
 
     -  Policy acquisition costs, such as commissions and other costs incurred
        in connection with acquiring new and renewal business, are expensed when
        incurred; under GAAP, such costs are deferred and amortized over the
        present value of expected gross margins.
 
     -  Premiums for universal life and investment-type products are recognized
        as revenue when due; under GAAP, they are reported as deposits to
        policyholders' account balances. Revenues from these contracts under
        GAAP consist of amounts assessed during the period against
        policyholders' account balances for mortality, policy administration and
        surrender charges.
 
     -  Policy reserves are based on statutory mortality and interest
        requirements, without consideration of withdrawals, and are reported net
        of reinsurance reserve credits; under GAAP, the reserves for interest
        sensitive life and annuity products are equal to the fund value, and the
        reserve for long duration participating contracts is the net level
        premium reserve calculated using the dividend fund interest rate and the
        mortality rates guaranteed in calculating cash surrender values. GAAP
        reserves are reported gross of reinsurance reserve credits.
 
     -  No provision is made for deferred income taxes; under GAAP, deferred
        income taxes result from temporary differences between the tax bases of
        assets and liabilities and their reported amounts in the financial
        statements.
 
     -  An interest maintenance reserve ("IMR") is established as a liability to
        capture realized investment gains and losses, net of tax, on the sale of
        fixed maturities and mortgage loans resulting from changes in the
        general level of interest rates, and is amortized into income over the
        remaining years to expected maturity of the assets sold; under GAAP, no
        such reserve is required.
 
     -  An asset valuation reserve ("AVR"), based upon a formula prescribed by
        the NAIC, is established as a liability to offset potential non-interest
        related investment losses, and changes in the AVR are charged or
        credited to surplus; under GAAP, no such reserve is required.
 
     -  Bonds and redeemable preferred stocks in good standing are generally
        carried at amortized cost; under GAAP, bonds and redeemable preferred
        stocks which are classified as available for sale are carried at fair
        value and the related change in unrealized gains and losses, net of
        related deferred taxes and an adjustment for deferred policy acquisition
        costs, is reported as a component of other comprehensive income in
        equity.
 
     -  Certain assets designated as "non-admitted," are excluded from assets by
        a direct charge to surplus; under GAAP, such assets are carried on the
        balance sheet, net of appropriate valuation allowances.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
3.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED):
     -  Pension expense for qualified defined pension plans is recognized when
        pension contributions are deductible for federal income tax purposes;
        under GAAP, pension expense for such plans is recognized as incurred
        over the service lives of employees participating in the plans.
 
     -  Postretirement benefits are accrued at the time employees are vested or
        retire; under GAAP, an obligation for such benefits is accrued over the
        service period for all eligible employees.
 
     -  Subsidiaries are not consolidated for statutory reporting purposes;
        under GAAP, all entities in which a company has control and a majority
        economic interest are consolidated.
 
     -  Surplus notes are reported as surplus for statutory purposes and as debt
        for GAAP.
 
     -  Certain reinsurance agreements recognized as reinsurance for statutory
        purposes are accounted for as financing transactions under GAAP.
 
     -  Methods used for calculating real estate and mortgage loan values and
        real estate depreciation under statutory reporting are different from
        those used for GAAP.
 
     -  Cash equivalents are defined as all highly liquid debt securities with
        original maturities of twelve months or less; under GAAP, cash
        equivalents are defined as short-term, highly liquid investments that
        generally have original maturities of three months or less.
 
     The following is a description of the Company's principal statutory
accounting policies:
 
  a. Premiums and Insurance Expenses
 
     Premiums are included in revenue over the premium payment periods of the
related policies. Annuity considerations and fund deposits are included in
revenue as received.
 
     The costs of acquiring new business, primarily commissions, underwriting,
agency and other costs related to issuance, maintenance and settlement of
policies are charged to operations in the year incurred.
 
  b. Investments
 
     Bonds are stated at amortized cost, except those bonds not in good
standing, which are carried at NAIC-designated values, which approximate fair
value. Loan-backed bonds and structured securities are valued at amortized cost
using the effective interest method considering anticipated prepayments at the
date of purchase; significant changes in the estimated cash flows from the
original purchase assumptions are accounted for using the retrospective method.
Redeemable preferred stocks are carried principally at cost except for those
securities in or near default, which are carried at fair value. Common stocks
are carried at fair value, except investments in subsidiaries, which are
generally carried on the equity basis. Policy loans are carried at their unpaid
principal balances. Short-term investments are carried at amortized cost and
consist of securities with original maturities of twelve months or less.
 
     Mortgage loans other than those in process of foreclosure are carried at
their unpaid principal balances adjusted for unamortized premium or discount.
Real estate owned for investment is carried at depreciated cost, less
encumbrances ($1.1 million in 1997 and $1.9 million in 1996). Cable television,
oil and gas, and real estate joint ventures and limited partnerships are
included in Other Invested Assets and are carried principally at their equity
value. Other investments are generally carried at cost.
 
     Real estate acquired through foreclosure is carried at the lower of cost,
less accumulated depreciation and encumbrances, if any, or estimated fair value
at the time of foreclosure. There were no encumbrances at December 31, 1997 or
1996. Mortgage loans in process of foreclosure are carried at the lower of the
carrying

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
3.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED):
value at the time of foreclosure or estimated fair value. Fair value is
determined by using the estimated discounted cash flows expected from the
underlying real estate properties. These projected cash flows are based on
estimates regarding future operating expenses, lease rates, occupancy levels and
investors' targeted yields.
 
     The Company provides, through a direct charge to surplus, an investment
valuation reserve for permanent impairment of real estate investments, joint
ventures and limited partnerships in real estate, mortgage loans delinquent for
more than 60 days and restructured mortgage loans. This reserve reflects, in
part, the excess of the carrying value of such assets over the estimated
undiscounted cash flows expected from the underlying real estate properties.
These projected cash flows are based on estimates similar to those described in
the preceding paragraph. As of December 31, 1997 and 1996, the Company's
investment valuation reserve was $140 million and $90 million, respectively.
 
     Realized capital gains and losses on sales of investments are determined on
the basis of specific identification. Unrealized capital gains and losses are
recorded directly to surplus. Investment income is recognized as earned.
Investment income earned includes the amortization of premium and accretion of
discount relative to bonds acquired at other than their par value and excludes
certain overdue due and accrued interest income.
 
  c. Interest Maintenance Reserve and Asset Valuation Reserve
 
     Realized investment gains and losses (net of tax) for bonds and mortgage
loans resulting from changes in interest rates are deferred, and credited or
charged to the IMR. These amounts are amortized into net income over the years
remaining to expected maturity of the assets sold.
 
     The AVR is based upon a formula prescribed by the NAIC and functions as a
reserve for potential non-interest related investment losses. In addition,
realized investment gains and losses (not subject to the IMR) and unrealized
gains and losses result in changes in the AVR, which are recorded directly to
surplus.
 
  d. Policy Reserves
 
     Policy reserves for life insurance, annuities, and supplemental benefits
are computed by using prescribed statutory interest rates and mortality factors.
Reserves computed by a modified commissioners' reserve valuation method
represent approximately 77 percent and 76 percent of gross life insurance
reserves at December 31, 1997 and 1996, respectively.
 
     Reserves for life insurance were principally determined by using the 1941,
1958 and 1980 Commissioners' Standard Ordinary Mortality and the American
Experience Tables and assumed interest rates ranging from 2.25 percent to 7
percent. Reserves for individual and group annuity mortality tables have assumed
interest rates ranging from 2.25 percent to 9.5 percent.
 
     Policy claims in process of settlement include provisions for payments to
be made on reported claims and on claims incurred but not reported.
 
  e. Investments in Unconsolidated Subsidiaries
 
     The Company's subsidiaries are not consolidated. The subsidiaries are
carried principally on the statutory equity basis. Changes in the Company's
equity in subsidiaries are included in unrealized capital gains and losses.
Dividends from subsidiaries are recognized as investment income when declared.

3.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED):
  f. Policyholder Dividends
 
     Dividends to policyholders are determined annually by the Board of
Trustees.
 
  g. Non-admitted Assets
 
     Certain assets designated as "non-admitted" assets (principally
miscellaneous receivables) are excluded from the statements of admitted assets,
liabilities and surplus.
 
  h. Separate Account Assets and Liabilities
 
     Separate account assets and liabilities represent primarily segregated
funds administered and invested by the Company for the benefit of certain
contractholders. Approximately 99 percent of these assets consist of securities
reported at market value and 1 percent consist of fixed maturity securities
carried at amortized cost. Premiums, benefits and expenses of the separate
accounts are included in the Company's statements of operations.
 
  i. Depreciation
 
     The Company uses the constant-yield method of depreciation for
substantially all investments in real estate, real estate joint ventures and
cable television limited partnerships acquired prior to January 1, 1991.
Acquisitions subsequent to January 1, 1991 and foreclosed real estate are
depreciated on the straight-line method. Real estate assets and improvements are
generally depreciated over ten to forty year periods and leasehold improvements
are depreciated over the lives of the leases. Depreciation expense related to
wholly owned investments in real estate was $30.8 million and $39.1 million in
1997 and 1996, respectively; accumulated depreciation was $191.7 million and
$213.6 million at December 31, 1997 and 1996, respectively.
 
  j. Special Surplus Funds
 
     Special surplus funds consist primarily of amounts required by the
Insurance Department of the State of New York to be assigned as surplus funds
for group insurance and aviation reinsurance.
 
  k. Cash Flows
 
     Short-term investments are characterized as cash equivalents for purposes
of the statements of cash flows.
 
     Certain amounts for 1996 have been reclassified to conform to the 1997
presentation.

     Amortized cost represents the principal amount of fixed maturity securities
adjusted by unamortized premium or discount and reduced by writedowns of $4.7
million and $16.6 million for bonds at December 31, 1997 and 1996, respectively,
as required by the NAIC for securities which are in or near default. There were
no writedowns for redeemable preferred stocks at December 31, 1997 and 1996.
 
     At December 31, 1997, 77.9% of the Company's Collateralized Mortgage

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
4.  FIXED MATURITY SECURITIES (CONTINUED):
     Fixed maturity securities that are not due at a single maturity date have
been included in the preceding table in the year of final maturity. Actual
maturities may differ from contractual maturities because borrowers may have the
right to call or prepay obligations with or without call or prepayment
penalties.
 
     Proceeds from sales of investments in bonds and redeemable preferred stocks
during 1997 and 1996 were $193.7 million and $173.8 million, respectively. Gross
gains of $1.8 million in 1997 and $3.8 million in 1996, and gross losses of $6.3
million in 1997 and $4.0 million in 1996 were realized on these sales.
 
     There were no non-income producing bonds and redeemable preferred stocks
for the twelve months preceding December 31, 1997. The carrying values of bonds
and redeemable preferred stocks which were non-income producing for the twelve
months preceding December 31, 1996 were $5.6 million.
 
5.  COMMON STOCKS:
 
     Common stocks include marketable equity securities carried at market values
of $185.3 million and $160.7 million at December 31, 1997 and 1996,
respectively, and non-marketable equity investments carried at estimated fair
value of $147.1 million and $140.1 million at December 31, 1997 and 1996,
respectively. The cost of the marketable equity securities was $171.9 million
and $142.2 million at December 31, 1997 and 1996 respectively. At December 31,
1997 and 1996, gross unrealized gains were $25.5 million and $23.6 million,
respectively, and gross unrealized losses were $12.1 million and $5.1 million,
respectively, for marketable equity securities.
 
     Proceeds from sales of investments in common stocks during 1997 and 1996
were $233.1 million and $164.7 million, respectively. Gross gains of $43.7
million in 1997 and $35.0 million in 1996, and gross losses of $4.7 million in
1997 and $8.7 million in 1996 were realized on these sales.

loans ($135 million) and separate account assets ($3.6 billion); and liabilities
of $4.8 billion, primarily life insurance and annuity reserves ($1.2 billion)
and separate account liabilities ($3.6 billion). Capital and surplus of MONY
America was $133.2 million as of December 31, 1997. In 1997 and 1996, total
revenues of MONY America were $898.4 million and $844.0 million, benefits and
expenses were $867.7 million and $819.8 million and net income, including

owned subsidiary of the Company. In 1996, the Company purchased $44.2 million of
commercial mortgages (plus accrued interest) from MONY Funding. The cash
proceeds from the mortgage and bond purchases in 1997 and 1996 were used by MONY
Funding to pay off Eurobond debt obligations due in 1997 and 1996.
 
     In 1997 the New York City Industrial Development Agency ("the NY IDA")
issued bonds for the benefit of the Company in the total amount of $16.0 million
related to the Company's consolidation of site locations to New York City. Debt
service under the bonds is funded by lease payments by the Company to the NY
IDA, bond trustee, for the benefit of the bondholder, MONY America (See Note
19).
 
     The Company and MONY America are parties to an agreement dated February 28,
1995 whereby the Company agrees to reimburse MONY America to the extent that
MONY America's recognized loss as a result of mortgage loan default or
foreclosure or subsequent sale of the underlying collateral exceeds 75 percent
of the appraised value of the loan at origination for each such mortgage loan.
Pursuant to the agreement, the Company made payments to MONY America totaling
$0.1 million in both 1997 and 1996.
 
     In February 1997, the Company ceased the operations of its subsidiaries,
ARES, Inc. and ARES Realty Capital (collectively "ARES"). ARES provided asset
management and property management services for the Company's real estate and
mortgage assets, as well as for third parties. The Company's management
agreement with ARES provided for payment by the Company for ARES's services
based upon third party commercial standards.
 
     The Company has service agreements with certain subsidiaries to provide
personnel services, facilities, supplies and equipment as shall reasonably be
necessary to conduct business. These agreements provide for reimbursement of
actual costs and are subject to cancellation upon written notice by either
party.
 
     The Company has an investment advisory agreement with its subsidiary, MONY
America, with respect to the investment and management of its assets. The
agreement provides for scheduled fees for actual cost reimbursements and may be
terminated by either party upon written notice.
 
7.  MORTGAGE LOANS AND REAL ESTATE:
 
     The Company invests in mortgage loans collateralized by commercial and
agricultural real estate. Such mortgage loans consist primarily of first
mortgage liens on completed income-producing properties. As of December 31,
1997, $410.2 million of mortgage loans have terms that require amortization, and
$1,026.1 million of mortgage loans require partial amortization or are
non-amortizing. Mortgage loans delinquent over 90 days or in process of
foreclosure were $12.7 million at December 31, 1997 and $14.7 million at
December 31, 1996. Properties acquired through foreclosure during the year
amounted to $14.4 million and $20.5 million in 1997 and 1996, respectively.
 
     The Company has performing restructured mortgage loans of $250.0 million as
of December 31, 1997 and $244.1 million as of December 31, 1996. The new terms
typically defer a portion of contract interest payments to future periods.
Interest is recognized in income based on the modified rate of the loan.
Deferred interest, which is the difference between the original contractual rate
and the modified rate, is excluded from income. Gross interest income on
restructured loans that would have been recorded in accordance with the loans'
original terms was approximately $23.6 million in 1997 and $22.8 million in
1996. Gross interest income recognized in net income for the period from these
loans was approximately $17.6 million in 1997 and $16.4 million in 1996. There
are no commitments to lend additional funds to any debtor involved in a
restructuring.
 
     At December 31, 1997 and 1996, the carrying values of mortgage loans which
were non-income producing for the twelve months preceding such dates were $26.1
million and $33.5 million, respectively.

</TABLE>
 
9.  ESTIMATED FAIR VALUE OF FINANCIAL INSTRUMENTS:
 
     The estimated fair values of mortgage loans, unaffiliated equity
securities, cash, short-term investments, separate account assets and
liabilities, investment-type contracts and short-term notes payable approximate
their carrying amounts. The carrying values of bonds and redeemable preferred
stocks were $4,708.8 million and $4,330.7 million at December 31, 1997 and 1996,
respectively. The estimated fair values of bonds and redeemable preferred stocks
were $4,873.7 million and $4,401.2 million at December 31, 1997 and 1996,
respectively.
 
     The calculations of estimated fair values involve considerable judgment.
Accordingly, these estimates of fair value are not necessarily indicative of the
values that could be negotiated in an actual sale.
 
     The methods and assumptions utilized in estimating these fair values of
financial instruments are summarized as follows:
 
  Bonds and redeemable preferred stocks (See Note 4)
 
     The estimated fair values of bonds and redeemable preferred stocks are
based upon quoted market prices, where available. The fair values of bonds and
redeemable preferred stocks not actively traded and other non-publicly traded
securities are estimated using values obtained from independent pricing services
or, in the case of private placements, by discounting expected future cash flows
using a current market interest rate commensurate with the credit quality and
term of the investments.
 
  Mortgage loans
 
     The fair values of mortgage loans are estimated by discounting expected
future cash flows, using current interest rates for similar loans to borrowers
with similar credit risk. Loans with similar characteristics are aggregated for
purposes of the calculations. The fair value of mortgage loans in process of
foreclosure is the estimated fair value of the underlying collateral.
 
  Policy loans
 
     Policy loans are an integral component of insurance contracts and have no
maturity dates. Management has determined that it is not practicable to estimate
the fair value of policy loans.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
9.  ESTIMATED FAIR VALUE OF FINANCIAL INSTRUMENTS (CONTINUED):
  Separate account assets and liabilities
 
     The estimated fair value of assets held in separate accounts is based
principally on quoted market prices. The fair value of liabilities related to
separate accounts is the amount payable on demand, net of surrender charges.
 
  Investment-type contracts
 
     The fair values of annuities are based on estimates of the value of
payments available upon full surrender. The fair values of the Company's
liabilities under guaranteed investment contracts are estimated by discounting
expected cash outflows using interest rates currently offered for similar
contracts with maturities consistent with those remaining for the contracts
being valued, where appropriate.
 
10.  OFF-BALANCE SHEET RISK AND CONCENTRATION OF CREDIT RISK:
 
  Financial Instruments with Off-Balance Sheet Risk:
 
     In 1992, the Company entered into an agreement with a bank to lend
securities to approved borrowers. There were $35.0 million of loaned securities
as of December 31, 1997. There were no loaned securities at December 31, 1996.
The minimum collateral on securities loaned is 102 percent of the market value
of loaned securities. Such securities are marked to market on a daily basis,
adjusting required collateral values accordingly.
 
  Concentration of Credit Risk:
 
     At December 31, 1997 and 1996, the Company had no single investment or
series of investments with a single issuer (excluding U.S. Government Agency
securities) exceeding 2.1 percent and 3.9 percent, respectively, of total cash
and invested assets.
 
     The bond portfolio is diversified by industry type. The industries that
comprise 10 percent or more of the carrying value of the bond portfolio at
December 31, 1997 are: Other Manufacturing of $671.6 million (14.2 percent),
Public Utilities of $596.5 million (12.7 percent), Consumer Goods and Services
of $477.4 million (10.2 percent), and Government and Agencies of $468.6 million
(10.0 percent). At December 31, 1996, the industries comprising 10 percent or
more of the bond portfolio carrying value were: Financial Services of $640.2
million (14.8 percent), Government and Agencies of $527.5 million (12.2
percent), Other Manufacturing of $524.0 million (12.1 percent), Public Utilities
of $501.5 million (11.6 percent), and Consumer Goods and Services of $436.3
million (10.1 percent).
 
     Below investment grade bonds are defined as those securities rated in
categories 3 through 6 by the NAIC, which are approximately equivalent to bonds
rated below BBB by rating agencies. These bonds consist mostly of privately
issued bonds, which are monitored by the Company through extensive internal
analysis of the financial condition of the borrowers, and which include
protective debt covenants. The Company held below investment grade bonds of
$218.4 million and $290.2 million at December 31, 1997 and 1996, respectively.
Of these bonds, $175.1 million and $239.6 million, respectively, were in
category 3, which is considered to be medium quality by the NAIC.

</TABLE>
 
     The amounts shown above are included in the Company's statement of admitted
assets, liabilities and surplus as life insurance and annuity reserves ($1.4
billion) and separate account liabilities ($1.8 billion).
 
12.  REINSURANCE:
 
     Life insurance business is ceded on a yearly renewable term basis under
various reinsurance contracts. The Company's general practice is to retain no
more than $4.0 million of risk on any one person for individual products and
$6.0 million for last survivor products.
 
     The total amount of reinsured life insurance in force on this basis was
$6.8 billion and $7.0 billion at December 31, 1997 and 1996, respectively.
Premiums ceded under these contracts were $36.0 million and $35.1 million;
benefit payments recovered were approximately $25.0 million and $31.5 million;
policy reserve credits recorded were $30.6 million and $30.9 million; and
recoverable amounts on paid and unpaid losses were $5.9 million and $10.5
million in 1997 and 1996, respectively.
 
     The Company reinsured certain whole life and endowment contracts issued
through 1974 under an agreement which combines the modified coinsurance and the
coinsurance bases. Reserves subject to this agreement were $919 million in 1997
and $936 million in 1996, for which the Company recorded policy reserve credits
of $44.0 million in 1997 and 1996. Premiums ceded under this contract were $17.8
million in 1997 and $22.3 million in 1996. The reinsurer is required to
reimburse the Company for its share of dividends paid on participating policies
under a formula based on the relationship between actual dividends and the
Company's general account earnings rate, which will in most instances result in
a payment equal to the reinsurer's percentage share of the Company's actual
dividends. The Company holds the entire dividend liability as a modified
coinsurance liability. In view of the fact that these reimbursements will not in
all instances equal the reinsurer's share of the Company's actual dividends, the
Company considers all dividend reimbursements as miscellaneous income.
 
     The Company also reinsured certain other whole life and endowment contracts
issued through 1974 under an agreement which combines the modified coinsurance
and the coinsurance bases. Reserves subject to this agreement were $750 million
in 1997 and $764 million in 1996, for which the Company recorded policy reserve
credits of $34.2 million in 1997 and 1996. Premiums ceded under this contract
were $16.2 million in

12.  REINSURANCE (CONTINUED):
1997 and $19.9 million in 1996. The reinsurer is required to reimburse the
Company for its share of dividends paid on participating policies under a
formula based on the relationship between actual dividends and the Company's
general account earnings rate, which will in most instances result in a payment
equal to the reinsurer's percentage share of the Company's actual dividends. The
reinsurer coinsures $16 million of the Company's dividend liability with the
balance of the dividend liability subject to a modified coinsurance arrangement.
In view of the fact that these reimbursements will not in all instances equal
the reinsurer's share of the Company's actual dividends, the Company records
dividend reimbursements for which it has a coinsurance credit as dividends
received with the remainder accounted for as miscellaneous income.
 
     The Company has coinsured a portion of its extended term insurance,
guaranteed interest contract and long-term disability claim liabilities. The
total ceded reserves and claims liabilities under these agreements were $42.3
million and $44.6 million at December 31, 1997 and 1996, respectively.
 
     During 1994, the Company entered into an agreement to reinsure
approximately 50% of its block of paid-up life insurance policies. The Company
transferred assets equal to the total liabilities ceded into a segregated
portfolio within its general account to secure benefit payments from the
reinsurer and established a funds held liability to the reinsurer for a
corresponding amount. Reserves ceded under this agreement were $90.6 million and
$96.9 million at December 31, 1997 and 1996, respectively.
 
     Prior to December 31, 1997, the Company had reinsured approximately 60
percent of its net retained individual disability ("DI") business under an
agreement that was novated on December 31, 1997. Ceded premiums under this
agreement were $43.6 million and $44.3 million during 1997 and 1996,
respectively. The ceded reserves and claims liabilities were $219.4 million
prior to novation on December 31, 1997, and $201.8 million at December 31, 1996.
 
     As of December 31, 1997, the in force block of DI policies has been 100
percent reinsured. Under the terms of this agreement, the reinsurer assumed the
treaty liabilities of the novated agreement discussed in the preceding paragraph
and additional liabilities of $153.4 million as of December 31, 1997; therefore,
total ceded reserves, claim and dividend liabilities at December 31, 1997 were
$372.8. The Company's statutory surplus increased by $21.2 million, net of tax,
as a result of this agreement and the novation discussed in the preceding
paragraph.
 
     The Company is contingently liable with respect to ceded reinsurance should
any reinsurer be unable to meet its obligations under these agreements. To limit
the possibility of such losses, the Company evaluates the financial condition of
its reinsurers and monitors concentration of credit risk.
 
13.  GROUP PENSION BUSINESS:
 
     On December 31, 1993, the Company entered into an agreement with AEGON USA,
Inc. ("AEGON") under which the Company agreed to sell substantially all of its
group pension business, including its full service group pension contracts,
consisting primarily of tax-deferred annuity, 401(k) and managed funds lines of
business, to AEGON's wholly-owned subsidiary, AUSA Life Insurance Company, Inc.
("AUSA Life"). The sale (the "Group Pension Transaction") was accomplished
through the transfer of $6.3 billion in group pension assets and liabilities,
including $2.7 billion of general account assets and $3.6 billion of separate
account assets. AUSA Life also acquired the corporate infrastructure supporting
the group pension business, including personnel, data processing systems,
facilities and regional offices. In connection with the transaction, the Company
and AEGON have entered into certain service agreements. These agreements, among
other things, provide that the Company will continue to manage the transferred
assets, and that AUSA Life will continue to provide certain administrative
services to the Company's remaining group pension contracts not included in the
transfer.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
13.  GROUP PENSION BUSINESS (CONTINUED):
     Effective with the agreement, AUSA Life reinsured, on an indemnity
reinsurance basis, the contract liabilities funded by such general account
assets. AUSA Life agreed to reinsure such general and separate account
liabilities on an assumption reinsurance basis upon the consent of general
account contractholders to assumption of their contracts. Substantially all of
the contractholders elected assumption reinsurance.
 
     In connection with the Group Pension Transaction, on December 31, 1993, the
Company made a $200 million capital investment in AEGON by purchasing $150
million face amount of Series A notes and $50 million face amount of Series B
notes ("the Notes"). The Series A notes pay interest at 6.44 percent per annum
and the Series B notes pay interest at 6.24 percent per annum. Both the Series A
and Series B notes mature on December 31, 2002.
 
     In addition to interest payments on the Notes, the Company has the right to
receive certain payments based on the profits of the transferred business in
force on the transaction date, a future payment tied to the determination of the
value of the transferred business at the maturity date of the Notes, and a
potential payment based on new business growth. Net operating losses, if any, on
the transferred business for any year are carried forward to reduce profit
payments in subsequent years. Any deficit remaining at the end of the nine-year
term of the Notes may only be applied to reduce the final value of the business
transferred and the principal amount of any outstanding Series A notes. For the
years ended December 31, 1997 and 1996, the Company earned $51.5 million and
$65.9 million, respectively, based upon the profits of the transferred group
pension business and reflected these amounts in Commission and Expense Allowance
on Reinsurance Ceded on the Company's statements of operations.
 
     From 1994 through 1996, the Company reinvested an aggregate of $169 million
of the aforementioned profits and interest in additional Series A notes (the
"Additional Notes") with a face amount equal to the amount reinvested. The
interest on the Additional Notes was 1 percent above the two-year U.S. Treasury
rate in effect at the time of their issuance. AUSA Life redeemed all of the
Additional Notes at face value during 1997.
 
     The Company held $150 million face amount of Series A notes and $50 million
face amount of Series B notes at December 31, 1997.
 
14.  NOTES PAYABLE:
 
     During 1997, the Company retired a remaining outstanding liability for
borrowed money related to a floating rate note issued by a trust which qualified
as a REMIC (Real Estate Mortgage Investment Conduit) under Section 860 of the
Internal Revenue Code. The remaining floating rate note issued by the trust
matured on September 25, 1997. The interest rate on the note issued by the trust
ranged from 5.69 percent to 6.00 percent during 1997 and 5.56 percent to 6.07
percent in 1996. Interest expense incurred was $0.8 million in 1997 and $3.3
million in 1996. Mortgage assets of the Company were previously pledged as
collateral for the trust. The Company had accounted for the trust which
qualified as a REMIC by consolidating the trust's mortgages and debt.
 
15.  SURPLUS NOTES:
 
     In 1994, the Company completed the sale of $125 million 30-year surplus
notes ("the Surplus Notes") which generated net proceeds of $70 million after a
discount of 42.146 percent from the principal amount payable at maturity and
issuance expenses of approximately $2.3 million. The $70 million of net proceeds
has increased the Company's surplus by a corresponding amount.The Company has
made no charge against its surplus for the accretion of discount on the Surplus
Notes as prescribed by the Insurance Department of the State of New York.
Interest on the Surplus Notes is scheduled to be paid on February 15 and August
15 of

each year, commencing February 15, 2000, at a rate of 11.25 percent per annum.
Each accrual and payment of interest on the Surplus Notes may only be made with
the prior approval of the New York State Superintendent of Insurance.
 
     As discussed in Note 2, under the terms of the Investment Agreement, the
Investors purchased the MONY Notes from the Company with an aggregate principal
amount of $115 million. The MONY Notes generated net proceeds of $111.4 million
after issuance expenses of $3.6 million. The MONY Notes bear interest at the
stated rate of 9.5 percent per annum and mature on December 30, 2012. Interest
on the MONY Notes is payable semi-annually and principal is payable at maturity.
Each accrual and payment of interest on the MONY Notes may only be made with the
prior approval of the New York State Superintendent of Insurance.
 
16.  FEDERAL INCOME TAXES:
 
     The Company files a consolidated federal income tax return with its life
and non-life subsidiaries. The allocation of federal income taxes is based upon
separate return calculations with current credit for losses and other federal
income tax credits provided to the life insurance members of the affiliated
group. Intercompany tax balances are settled annually in the fourth quarter.
 
     The Company's federal income tax returns for years through 1991 have been
examined with no proposed material adjustments. In the opinion of management,
adequate provision has been made for any additional taxes which may become due
with respect to open years.
 
     Pre-tax operating gains and pre-tax operating losses, as reported in the
accompanying statements of operations, differ from the taxable income reported
for tax purposes. Significant differences include the deferral and amortization
of policy acquisition costs for tax purposes, the difference between statutory
and tax reserves, the taxable portion of the Company's surplus (as applicable to
mutual life insurers), depreciation expense and related recapture, capital gains
deferred to the IMR, and equity in partnerships and joint ventures.
 
17.  PENSION PLANS AND OTHER POSTRETIREMENT BENEFITS:
 
  Employee and Field Underwriter Retirement Plans
 
     The Company has a qualified pension plan covering substantially all of its
salaried employees. The provisions of the plan provide both (a) defined benefit
accruals based on (i) years of service, (ii) the employee's final average annual
compensation and (iii) wage bases or benefits under Social Security and (b)
effective January 1, 1994, defined contribution accruals based on a Company
matching contribution equal to 100 percent of the Company employee's elective
deferrals under the incentive savings plan for employees up to 3 percent of the
employee's eligible compensation and an additional 2 percent of eligible
compensation for each active participant. The Company's funding and accounting
policies are to contribute annually the maximum amount that can be deducted for
federal income taxes and to charge expenses in the year in which the
contributions are made. No contributions were made in the current year or prior
year because the plan was subject to the full funding limitation under Section
412 of the Internal Revenue Code. At December 31, 1996, the most recent
actuarial valuation date, the plan's accumulated benefit obligation, determined
in accordance with Statements of Financial Accounting Standards and based on an
assumed settlement rate of 7.50 percent, was $276.2 million including vested
benefits of $274.4 million. The fair value of Plan assets as of December 31,
1996 was $393.4 million.
 
     The Company also has a qualified money purchase pension plan covering
substantially all career field underwriters. Company contributions of 5 percent
of earnings plus an additional 2 percent of such earnings in

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
17.  PENSION PLANS AND OTHER POSTRETIREMENT BENEFITS (CONTINUED):
excess of the social security wage base are made each year. In addition,
after-tax voluntary field underwriter contributions of up to 10 percent of
earnings are allowed. At December 31, 1996, the latest actuarial valuation date,
the fair value of plan assets was $191.1 million. For the years ended December
31, 1997 and 1996, the Company contributed $3.3 million and $3.7 million to the
plan, respectively.
 
     The Company sponsors a non-qualified defined benefit pension plan, which
provides benefits in excess of Internal Revenue Service limits to certain
employees. The benefits are based on years of service and the employee's final
average annual compensation. Pension benefits are paid from the Company's
general account. The amounts accrued by the Company for this plan, based on an
assumed 7.50 percent average interest rate for 1997 and 7.42 percent weighted
average interest rate for 1996 were $38.2 million and $36.9 million in 1997 and
1996, respectively. The Company also maintains various non-qualified excess
defined contribution plans for field underwriters and key employees. The amounts
accrued for these various plans were $80.2 million and $67.5 million in 1997 and
1996, respectively.
 
  Deferred Compensation Plans
 
     The Company has incentive savings plans in which substantially all
employees and career field underwriters are eligible to participate. The Company
matches field underwriter contributions up to 2 percent of eligible
compensation, as defined, and may also make an additional profit sharing
contribution for non-officer employees. The Company made employer contributions
of $2.4 million and $2.5 million to these plans in 1997 and 1996, respectively.
In addition, the Company has two compensation plans for key employees that allow
deferral of current compensation, as allowed by New York Insurance Law.
 
  Postretirement Benefits Other than Pensions
 
     The Company provides certain health care and life insurance benefits
("postretirement benefits") for retired employees and field underwriters. The
Company accrues the estimated employee cost of retiree benefit payments for
current retirees and fully vested employees and field underwriters by estimating
the actuarial present value of benefits expected to be paid after retirement.
 
     At December 31, 1997 and 1996, the unamortized portion of the
postretirement benefit transition obligation established at December 31, 1992,
was approximately $54.0 million and $57.6 million, respectively. The Company
amortizes this transition obligation over a period of twenty years. The amount
of transition obligation amortized approximated $3.6 million during 1997 and
1996. The total cost to provide life insurance and health benefits for fully
vested and retired employees and field underwriters, including the expense
described above, was $11.2 million in 1997 and $10.6 million in 1996.
 
     At December 31, 1997, the unfunded postretirement benefit obligation for
retirees and fully vested employees was $91.8 million, with $25.9 million
included in Other Liabilities. At December 31, 1996, the unfunded postretirement
benefit obligation for retirees and fully vested employees was $76.3 million,
with $21.4 million included in Other Liabilities. The discount rate used in
determining the accumulated postretirement benefit obligation was 6.75 percent
and 7.50 percent in 1997 and 1996, respectively, and the health care cost trend
rate was 11.0 percent graded to 6.0 percent by 2010 for 1997 and 1996.
 
     The health care cost trend rate assumption has an effect on the amounts
reported. To illustrate, an increase in the assumed health care cost trend rates
of one percentage point in each year would increase the estimated postretirement
benefit obligation as of December 31, 1997 by $0.8 million and the estimated
eligibility cost and interest cost components of net periodic postretirement
benefit cost for 1997 by $0.1 million.

18.  COMMITMENTS AND CONTINGENCIES:
 
  Commitments:
 
     The Company maintains lines of credit with domestic banks totaling $100
million. The Company intends to renew the line of credit on June 30, 1998, the
next scheduled renewal date. The Company has not borrowed against its credit
lines since 1982.
 
     At December 31, 1997 the Company had commitments to issue $29.1 million of
fixed rate farm loans with interest rates ranging from 7.45 percent to 8.0
percent and terms based on rate reset dates of 1 to 10 years. The Company also
committed to $36.4 million of commercial loan investments with interest rates
ranging from 7.23 percent to 8.17 percent and terms of 5 to 15 years. There were
$41.0 million outstanding bond commitments as of December 31, 1997.
 
  Contingencies:
 
     The Company has guaranteed to certain states that the surplus of MONY
America will be maintained at amounts at least equal to the minimum surplus
required for admission to those states.
 
     At December 31, 1997, the Company has guaranteed $34 million related to
real estate held by unrelated investors.
 
     In late 1995 and during 1996, a number of purported class actions were
commenced in various state and federal courts against the Company and MONY
America ("the Companies") alleging that the Companies engaged in deceptive sales
practices in connection with the sale of whole and universal life insurance
policies during the period 1980 to the present. Although the claims asserted in
each case are not identical, they seek substantially the same relief under
essentially the same theories of recovery (i.e. breach of contract, fraud,
negligent misrepresentation, negligent supervision and training, breach of
fiduciary duty, unjust enrichment and violation of state insurance and/or
deceptive business practice laws). The Companies have answered the complaints in
each action (except for one being voluntarily held in abeyance), have denied any
wrongdoing, and have asserted numerous affirmative defenses.
 
     On June 7, 1996, the New York State Supreme Court certified the Goshen
case, being the first of the aforementioned class actions filed, as a nationwide
class consisting of all persons or entities who have, or at the time of the
policy's termination, had an ownership interest in a whole or universal life
insurance policy issued by the Companies and sold on an alleged "vanishing
premium" basis during the period January 1, 1982 to December 31, 1995. On March
27, 1997, the Companies filed a motion to dismiss or, alternatively, motion for
summary judgment on all counts of the complaint.
 
     The Massachusetts District Court in the Multidistrict Litigation has
entered an order recognizing the Goshen case as the lead case and essentially
holding all of the federal cases in abeyance pending the action of the Goshen
case. Consequently, all other putative class actions have been either
consolidated and transferred by the Judicial Panel on Multidistrict Litigation
to the United States District Court for the District of Massachusetts, or are
being voluntarily held in abeyance pending the outcome of the Goshen case.
 
     On October 21, 1997, the New York State Supreme Court granted the
Companies' motion for summary judgment and dismissed all claims filed in the
Goshen case against the Companies. The order by the New York State Supreme Court
has been appealed to the Appellate Division by plaintiffs and all actions before
the United States District Court for the District of Massachusetts are still
pending.
 
     In addition to the matters discussed above, the Company is involved in
various other legal actions and proceedings in connection with its businesses.
The claimants in certain of these actions and proceedings seek damages of
unspecified amounts. During 1996, litigation settlements of $12.6 million
related to prior years' events were charged directly to surplus.

                 THE MUTUAL LIFE INSURANCE COMPANY OF NEW YORK
 
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
18.  COMMITMENTS AND CONTINGENCIES (CONTINUED):
     While the outcome of such matters cannot be predicted with certainty, in
the opinion of management, any additional liability beyond that recorded in the
financial statements at December 31, 1997, resulting from the resolution of
these matters will not have a material adverse effect on the Company's statutory
surplus or results of operations.
 
     In 1994, the Company reached an agreement for the transfer of the
management of its information systems operations to Computer Sciences
Corporation ("CSC"). Under the terms of this agreement, CSC agreed to operate,
manage and enhance the Company's information systems operations. In 1997, the
Company and CSC mutually agreed to terminate all agreements between them. In
connection with the termination, the Company paid $21.2 million to CSC.
 
     Insurance companies are subject to assessments, up to statutory limits, by
state guaranty funds for losses of policyholders of insolvent insurance
companies. In the opinion of management, such assessments will not have a
material adverse effect on the Company's statutory surplus or results of
operations.
 
19.  LEASES:
 
   
     The Company has entered into various operating and capital lease agreements
for office space and furniture and equipment, including a 17-year capital with
the NY IDA (See Note 6). The Company's leases have remaining non-cancelable
lease terms in excess of one year. Total rental expense for these leases
amounted to $22.4 million in 1997 and $21.8 million in 1996.
    
 
     The future minimum rental obligations under these leases at December 31,
1997 are as follows:

20.  YEAR 2000:
 
     The Year 2000 issue is the result of the widespread use of computer
programs written using two digits (rather than four) to define the applicable
year. Such programming was a common industry practice designed to avoid the
significant costs associated with additional mainframe capacity necessary to
accommodate a four-digit year field. 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 systems
failure or miscalculations. The Company has conducted a comprehensive review of
its computer systems to identify the systems that could be affected by the Year
2000 issue and has developed and implemented a plan to resolve the issue. The
Company currently believes that, with modifications to existing software and
converting to new software, the Year 2000 issue will not pose significant
operational problems for the Company's computer systems. However, if such
modifications and conversions are not completed on a timely basis, the Year 2000
issue may have a material impact on the operations of the Company. Furthermore,
even if the Company completes such modifications and conversions on a timely
basis, there can be no assurance that the failure by vendors or other third
parties to solve the Year 2000 problem will not have a material impact on the
operations of the Company. The Company estimates the total cost to resolve its
Year 2000 problem to be approximately $18 million.

ITEM 27.  NUMBER OF CERTIFICATE OWNERS:
 
   
     As of December 31, 1997, MONY Variable Account A had 10,996 owners of

ITEM 28.  INDEMNIFICATION
 
     The By-Laws of The Mutual Life Insurance Company of New York provide, in
Article XVI 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 Chapter 513, 1986 Laws of New York, the Board of Trustees may
adopt all resolutions, authorize all agreements and take all actions with
respect to the indemnification of trustees 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 The Mutual
Life Insurance Company of New York ("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 1997 and 1996.
    
 
ITEM 30.  LOCATION OF ACCOUNTS AND RECORDS

31(a) of the Investment Company Act of 1940 and the Rules promulgated thereunder
are maintained by The Mutual Life Insurance Company of New York, in whole or in
