FORWARD-LOOKING STATEMENTS
 
     The management of The MONY Group Inc. (the "Company") has made in this
report, and from time to time may make in its public filings and press releases
as well as in oral presentations and discussions, forward-looking statements
concerning the Company's operations, economic performance and financial
condition. Forward-looking statements include, among other things, discussions
concerning the Company's potential exposure to market risks, as well as
statements expressing management's expectations, beliefs, estimates, forecasts,
projections and assumptions, as indicated by words such as "believes,"
"estimates," "intends," "anticipates," "expects," "projects," "should,"
"probably," "risk," "target," "goals," "objectives," or similar expressions. The
Company claims the protection afforded by the safe harbor for forward-looking
statements contained in the Private Securities Litigation Reform Act of 1995,
and assumes no duty to update any forward-looking statement. Forward-looking
statements are subject to risks and uncertainties. Actual results could differ
materially from those anticipated by forward-looking statements due to a number
of important factors including those discussed elsewhere in this report and in
the Company's other public filings, press releases, oral presentations and
discussions and the following: (i) losses with respect to the Company's equity
real estate, and the success of the Company's continuing process of selectively
selling its equity real estate; (ii) the success of the recently implemented
"tiering" of the Company's career agency sales force, and the ability to attract
and retain productive agents; (iii) the Company's ability to control operating
expenses; (iv) a successful appeal of the order of the New York Superintendent
of Insurance approving the Company's plan of reorganization; (v) a successful
appeal of the decision and order of the New York State Appellate Division, First
Department, affirming the successful appeal of the decision and order of the New
York Supreme Court grant of summary judgement in the case of Goshen v. The
Mutual Life Insurance Company of New York; (vi) the cost of defending other
litigation and the risk of unanticipated material adverse outcomes in such
litigation; (vii) deterioration in the experience of the closed block
established in connection with the Company's Demutualization, as hereafter
defined; (viii) the performance of the stock markets; (ix) the intensity of
competition from other financial institutions; (x) the Company's mortality,
morbidity, persistency and claims experience; (xi) the Company's ability to
develop, distribute and administer competitive products and services in a
timely, cost-effective manner; (xii) the Company's financial and claims paying
ratings; (xiii) the effect of changes in laws and regulations affecting the
Company's businesses, including changes in tax laws affecting insurance and
annuity products; (xiv) market risks related to interest rates, equity prices,
derivatives, foreign currency exchange and credit; (xv) the ability of the
Company to identify and consummate on successful terms any future acquisitions,
and to successfully integrate acquired businesses with minimal disruption and
(xvi) the risks associated with Year 2000 non-compliance by the Company and
third-parties (including vendors and suppliers, reinsurers and others doing
business with the Company), unanticipated costs associated with Year 2000
compliance due to, among other things the inability to locate, correct and
successfully test all relevant computer code according to schedule, the
continued availability of resources including personnel and timely and accurate
responses and corrections by third parties.

                      THE MONY GROUP INC. AND SUBSIDIARIES
 
               NOTES TO UNAUDITED INTERIM CONDENSED CONSOLIDATED
                              FINANCIAL STATEMENTS
 
1.  ORGANIZATION AND DESCRIPTION OF BUSINESS:
 
     On November 16, 1998, pursuant to its Plan of Reorganization (the "Plan")
which was approved by the New York Superintendent of Insurance on the same day
(the "Plan Effective Date"), The Mutual Life Insurance Company of New York
("MONY") converted from a mutual life insurance company to a stock life
insurance company (the "Demutualization") and became a wholly owned subsidiary
of The MONY Group Inc., (the "MONY Group"), a Delaware corporation organized on
June 24, 1997 for the purpose of becoming the parent holding company of MONY.
The MONY Group has no other operations or subsidiaries. In connection with the
Plan, MONY established a closed block, to fund the guaranteed benefits and
dividends of certain participating insurance policies and eligible policyholders
received cash, policy credits, or shares of common stock of the MONY Group in
exchange for their membership interests in MONY. Also, on November 16, 1998, the
MONY Group consummated an initial public offering (the "Offerings") of
approximately 12.9 million shares of its common stock and MONY changed its name
to MONY Life Insurance Company (MONY Life Insurance Company and its subsidiaries
are hereinafter referred to as "MONY Life"). The shares of common stock issued
in the Offerings are in addition to approximately 34.3 million shares of common
stock of the MONY Group distributed to the aforementioned policyholders.
 
     The MONY Group, through MONY Life and its subsidiaries (hereafter
collectively referred to as the "Company"), is 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 primarily through its
career agency sales force. The Company primarily sells its products in all 50 of
the United States, the District of Columbia, the U.S. Virgin Islands, Guam and
the Commonwealth of Puerto Rico.
 
     On December 31, 1998, MONY Life acquired Sagamore Financial Corporation
("Sagamore"), the parent company of U.S. Financial Life Insurance Company
("USFL") for a purchase price of $48 million. USFL is a special-risk carrier
based in Ohio, which distributes its products in 41 states through brokerage
general agencies.
 
2.  BASIS OF PRESENTATION:
 
     The accompanying unaudited interim condensed consolidated financial
statements are prepared in conformity with generally accepted accounting
principles ("GAAP") which requires management to make estimates and assumptions
that affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period. In
the opinion of management these statements include all adjustments which were
normal recurring adjustments necessary to present fairly the financial position,
results of operations and cash flows for the periods presented. These statements
should be read in conjunction with the consolidated financial statements of the
Company for the year ended December 31, 1998 in the Company's Form 10-K. The
results of operations for the three-month periods ended March 31, 1999 are not
necessarily indicative of the results to be expected for the full year. Certain
reclassifications have been made in the amounts presented for prior periods to
conform those periods to the current presentation.
 
3.  SEGMENT INFORMATION:
 
     The Company's business activities consist of the following: protection
product operations, accumulation product operations, mutual fund operations,
securities broker-dealer operations, insurance brokerage operations, and certain
insurance lines of business no longer written by the Company (the "run-off
businesses"). These business activities represent the Company's operating
segments. Except as discussed below, these segments are managed separately
because they either provide different products or services, are subject to
different regulation, require different strategies, or have different technology
requirements.
 
     Management considers the Company's mutual fund operations to be an integral
part of the products offered by the Company's accumulation products segment,
since substantially all the mutual funds sold by the Company are offered
through, and in conjunction with, the products marketed by the accumulation
products segment. Accordingly, for management purposes (including, performance
assessment and making decisions regarding the allocation of resources), the
Company aggregates its mutual fund operations with its accumulation products
segment.
 
     Of the aforementioned segments, only the protection products segment and
the accumulation products segment qualify as reportable segments in accordance
with FASB Statement No. 131. All of the Company's other segments are combined
and reported in an other products segment.
 
     Products comprising the protection products segment primarily include a
wide range of individual life insurance products, including; permanent and last
survivor whole life, term life, universal life, variable universal life, group
life, and group universal life. In addition, included in the protection products
segment are: (i) the assets and liabilities transferred pursuant to the Group
Pension Transaction, as well as the Group Pension Profits (see Note 4), (ii) the
Closed Block

                      FINANCIAL STATEMENTS -- (CONTINUED)
 
assets and liabilities, as well as the Contribution from the Closed Block which
is reflected in "Other Income" in the table below (see Note 6), and (iii) the
Company's disability income insurance business. Products comprising the
accumulation products segment primarily include fixed annuities,
non-participating interest sensitive products (including; single premium
deferred annuities, flexible premium deferred annuities, immediate annuities,
and flexible premium variable annuities), proprietary mutual funds, investment
management services, and certain other financial services products. The
Company's other products segment primarily consists of the securities
broker-dealer operation, the insurance brokerage operation, and the run-off
businesses. The securities broker-dealer operation markets the Company's
proprietary investment products and, in addition, provides customers of the
Company's protection and accumulation products access to other non-proprietary
investment products (including stocks, bonds, limited partnership interests,
tax-exempt unit investment trusts and other investment securities). The
insurance brokerage operation provides the Company's field agency force with
access to life, annuity, small group health and specialty insurance products
written by other carriers to meet the insurance and investment needs of its
customers. The run-off businesses primarily consist of group life and health
business, as well as group pension business that was not included in the Group
Pension Transaction (See Note 4).
 
     Set forth in the table below is certain financial information with respect
to the Company's operating segments as of March 31, 1999 and December 31, 1998
and for the three-month periods ended March 31, 1999 and 1998, as well as
amounts not allocated to the segments. The Company evaluates the performance of
each operating segment based on profit or loss from operations before income
taxes and nonrecurring items (e.g. items of an unusual or infrequent nature).
The Company does not allocate certain nonrecurring items to the segments. In
addition, all segment revenues are from external customers.
 
     Assets have been allocated to the segments in amounts sufficient to support
the associated liabilities of each segment. In addition, capital is allocated to
each segment in amounts sufficient to maintain a targeted regulatory risk-based
capital ("RBC") level for each segment. Allocations of net investment income and
net realized gains on investments were based on the amount of assets allocated
to each segment. Other costs and operating expenses were allocated to each of
the segments based on: (i) a review of the nature of such costs, (ii) time
studies analyzing the amount of employee compensation costs incurred by each
segment, and (iii) cost estimates included in the Company's product pricing.
Substantially all non-cash transactions and impaired real estate (including real
estate acquired in satisfaction of debt) have been allocated to the protection
products segment.
 
     Amounts reported as "unallocated amounts" in the table below primarily
relate to: (i) contracts issued by MONY Life relating to its employee benefit
plans, and (ii) assets, liabilities, revenues and expenses of the MONY Group.

4.  THE GROUP PENSION TRANSACTION:
 
     On December 31, 1993 (the "Group Pension Transaction Date"), MONY entered
into an agreement (the "Agreement") with AEGON USA, Inc. ("AEGON") under which
MONY transferred a substantial portion of its group pension business (hereafter
referred to as the "Group Pension Transaction"), 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"). The Company also transferred to AUSA the
corporate infrastructure supporting the group pension business, including data
processing systems, facilities and regional offices. AUSA was newly formed by
AEGON solely for the purpose of facilitating this transaction. 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 will continue to
provide certain administrative services to the Company's remaining group pension
contracts not included in the transfer.
 
     The transferred group pension business consisted of approximately $6.4
billion in group pension assets and liabilities, which were comprised of
approximately $2.8 billion of general account assets and liabilities, and $3.6
billion of separate account assets and liabilities. The transfer was initially
structured in the form of indemnity reinsurance, however, the Agreement
contemplated that the transfer would be restructured in the form of assumption
reinsurance as soon as practicable following the consent of contractholders to
assumption of their contracts. Substantially all of the contractholders
consented to the assumption of their contracts by AUSA.
 
     In addition, pursuant to the Agreement, MONY agreed to make 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 (hereinafter referred to as
the "Notes"). The Series A Notes pay interest at 6.44% per annum and the Series
B Notes pay interest at 6.24% per annum. Both the Series A Notes and the Series
B Notes mature on December 31, 2002. MONY's investment in the Series A Notes was
intended to provide AEGON with the funding necessary to capitalize AUSA.
 
     MONY retained all the profits resulting from the $6.4 billion of deposits
on contracts in force and transferred to AEGON on the Group Pension Transaction
Date (the "Existing Deposits"). As consideration for the transaction, MONY
remunerated AEGON by transferring to AUSA (i) the intangible value associated
with MONY's group pension franchise, including established customer
relationships, (ii) rights to substantially all the profits associated with any
new deposits made after the Group Pension Transaction Date on the contracts
which were in force and transferred by MONY

                      THE MONY GROUP INC. AND SUBSIDIARIES
 
               NOTES TO UNAUDITED INTERIM CONDENSED CONSOLIDATED
                      FINANCIAL STATEMENTS -- (CONTINUED)
 
to AUSA on the Group Pension Transaction Date, and (iii) rights to substantially
all the profits on any new business generated subsequent to the Group Pension
Transaction Date.
 
     In accordance with GAAP, the transaction did not constitute a sale because
MONY retained substantially all the risks and rewards associated with the
Existing Deposits. Accordingly, the Company continues to reflect the transferred
assets and liabilities on its balance sheet under separate captions entitled
"Assets transferred in Group Pension Transaction" and "Liabilities transferred
in Group Pension Transaction". In addition, MONY reports in its GAAP earnings
the profits from the Existing Deposits as discussed below.
 
     Pursuant to the Agreement, MONY receives from AUSA (i) payments on an
annual basis through December 31, 2002 (the "Group Pension Payments") equal to
all of the earnings from the Existing Deposits, (ii) a final payment (the "Final
Value Payment") at December 31, 2002 based on the remaining fair value of the
Existing Deposits, and (iii) a contingent payment (the "New Business Growth
Payment") at December 31, 2002 based on new business growth subsequent to the
Group Pension Transaction Date. However, the level of new business growth
necessary for MONY to receive the New Business Growth Payment make it unlikely
that MONY will ever receive any such payment.
 
     With respect to the Group Pension Payments, the annual results from the
Existing Deposits are measured on a basis in accordance with the Agreement (such
basis hereafter referred to as the "Earnings Formula") which is substantially
the same as GAAP, except that: (i) asset impairments on fixed maturity
securities are only recognized when such securities are designated with a
National Association of Insurance Commissioners ("NAIC") rating of  "6", and
(ii) no impairment losses are recognized on mortgage loans until such loans are
disposed of or at the time, and in the calculation, of the Final Value Payment.
 
     Earnings which emerge from the Existing Deposits pursuant to the
application of the Earnings Formula are recorded in MONY's financial statements
only after adjustments (primarily to recognize asset impairments in accordance
with SFAS Nos. 114 and 115) to reflect such earnings on a basis entirely in
accordance with GAAP (such earnings hereafter referred to as the "Group Pension
Profits"). Losses which arise from the application of the Earnings Formula for
any annual period will be reflected in MONY's results of operations (after
adjustments to reflect such losses in accordance with GAAP) only up to the
amount for which MONY is at risk (as described below), which at any time is
equal to the then outstanding principal amount of the Series A Notes.
 
     Operating losses reported in any annual period pursuant to the Earnings
Formula are carried forward to reduce any earnings in subsequent years reported
pursuant to the Earnings Formula. Any resultant deficit remaining at December
31, 2002 will be deducted from the Final Value Payment and New Business Growth
Payment, if any, due to MONY. If a deficit still remains, it will be applied (as
provided for in the Agreement) as an offset against the principal payment due to
MONY upon maturity of the Series A Notes.

5.  COMMITMENTS AND CONTINGENCIES:
 
     In late 1995 and thereafter, a number of purported class actions were
commenced in various state and federal courts against the Company alleging that
the Company engaged in deceptive sales practices in connection with the sale of
whole and/or universal life insurance policies from the early 1980s to the mid
1990s. 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/or
violation of state insurance and/or deceptive business practice laws).
Plaintiffs in these cases (including the Goshen case discussed below) seek
primary equitable relief (e.g. reformation, specific performance, mandatory
injunctive relief prohibiting the Company from canceling policies for failure to
make required premium payments, imposition of a constructive trust and/or
creation of a claims resolution facility to adjudicate any individual issues
remaining after resolution of all class-wide issues) as opposed to compensatory
damages, although they seek compensatory damages in unspecified amounts. The
Company has answered the complaints in each action (except for one recently
filed action and another being voluntarily held in abeyance), has denied any
wrongdoing, and has 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 Company and sold on an alleged "vanishing
premium" basis during the period January 1, 1982 to December 31, 1995. On March
27, 1997, the Company filed a motion to dismiss or, alternatively, for summary
judgment on all counts of the complaint. All of the other putative class actions
(with one exception discussed below) have been 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. The Massachusetts District
Court in the Multidistrict Litigation has entered an order essentially holding
all of the federal cases in abeyance pending the action of the Goshen case.
 
     On October 21, 1997, the New York State Supreme Court granted the Company's
motion for summary judgment and dismissed all claims filed in the Goshen case
against the Company on the merits. On March 18, 1999 the order by the New York
State Supreme Court was affirmed by the New York State Appellate Division, First
Department. On April 19, 1999, plaintiffs filed a motion to the New York State
Court of Appeals for leave to appeal from the final determination of the
Appellate Division which affirmed the New York Supreme Court's order granting
summary judgment and dismissing the complaint. All actions before the United
States District Court for the District of Massachusetts are still pending. In
addition, on or about February 25, 1999, a purported class action was filed
against MONY Life Insurance Company of America ("MLOA") in Kentucky state court
covering policyholders who purchased individual universal life insurance
policies from MLOA after January 1, 1988 claiming breach of contract and
violations of the Kentucky Consumer Protection Act. On March 26, 1999, MLOA
removed that action to the United States District Court for the Eastern District
of Kentucky, requested the Judicial Panel on multidistrict litigation to
transfer the action to the multidistrict litigation in the District of
Massachusetts and sought a stay of further proceedings in the Kentucky District
Court pending a determination on multidistrict transfer. On April 19, 1999, the
Judicial Panel entered a conditional transfer order transferring the case to the
Federal District Court in Massachusetts. Plaintiffs have submitted a motion in
opposition to the transfer.
 
     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.
 
     While the outcome of such matters cannot be predicted with certainty, in
the opinion of management, any additional liability beyond that recorded in the
consolidated financial statements at March 31, 1999, resulting from the
resolution of these matters will not have a material adverse effect on the
Company's consolidated financial position or results of operations.
 
     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 consolidated financial position and the results
of operations of the Company.
 
     The Company maintains two lines of credit with domestic banks aggregating
$150.0 million, with scheduled renewal dates in September 1999 and September
2003. Under these lines of credit, the Company is required to maintain a certain
statutory tangible net worth and debt to capitalization ratio. The Company has
not borrowed against these lines of credit since their inception.
 
     At March 31, 1999, the Company had commitments to issue $40.8 million of
fixed rate agricultural loans with periodic interest rate reset dates. The
initial interest rates on such loans range from approximately 6.75% to 7.80%. In
addition, the Company had commitments to issue $109.9 million of fixed rate
commercial mortgage loans with interest

rates ranging from 6.88% to 8.09%. The Company also had commitments outstanding
to purchase $75.4 million of private fixed maturity securities as of March 31,
1999 with interest rates ranging from 6.4% to 9.2%. At March 31, 1999, the
Company had commitments to contribute capital to its equity partnership
investments of $110.4 million.
 
6.  CLOSED BLOCK:
 
     On November 16, 1998, the Company established a closed block (the "Closed
Block") of certain participating insurance policies as defined in the Plan (the
"Closed Block Business"). In conjunction therewith, the Company allocated assets
to the Closed Block expected to produce cash flows which, together with
anticipated revenues from the Closed Block Business, are reasonably expected to
be sufficient to support the Closed Block Business, including but not limited
to, provision for payment of claims and surrender benefits, certain expenses and
taxes, and for continuation of current payable dividend scales in effect at the
date of Demutualization, assuming the experience underlying such dividend scales
continues, and for appropriate adjustments in such scales if the experience
changes. The assets allocated to the Closed Block and the aforementioned
revenues inure solely to the benefit of the owners of policies included in the
Closed Block.
 
     The assets and liabilities allocated to the Closed Block are recorded in
the Company's financial statements at their historical carrying values. The
carrying value of the assets allocated to the Closed Block are less than the
carrying value of the Closed Block liabilities at the Plan Effective Date. The
excess of the Closed Block liabilities over the Closed Block assets at the Plan
Effective Date represents the total estimated future post-tax contribution
expected to emerge from the operation of the Closed Block, which will be
recognized in the Company's income over the period the policies and the
contracts in the Closed Block remain in force.
 
     In determining the amount of assets to be allocated to the Closed Block,
management made certain estimates and assumptions regarding the expected cash
flows from the Closed Block assets and the Closed Block Business, including
estimates and assumptions regarding investment cash flows, mortality,
persistency, and expenses which are to be funded in the Closed Block. The
estimated net cash flows assumed in determining the Closed Block funding
consisted of premiums from policies included in the Closed Block, investment
income from Closed Block assets, proceeds from maturities and dispositions of
Closed Block assets, less benefits paid on Closed Block policies, certain
expenses (including taxes) funded in the Closed Block, and dividends on Closed
Block policies based on current payable dividend scales. To the extent that the
actual cash flows, subsequent to the Plan Effective Date, from the assets
allocated to the Closed Block and the Closed Block Business are, in the
aggregate, more favorable than assumed in establishing the Closed Block, total
dividends paid to the Closed Block policyholders in future years will be greater
than the total dividends that would have been paid to such policyholders if the
current payable dividend scales had been continued. Conversely, to the extent
that the actual cash flows, subsequent to the Plan Effective Date, from the
assets allocated to the Closed Block and the Closed Block Business are, in the
aggregate, less favorable than assumed in establishing the Closed Block, total
dividends paid to the Closed Block policyholders in future years will be less
than the total dividends that would have been paid to such policyholders if the
current payable dividend scales had been continued. Accordingly, the recognition
of the aforementioned estimated future post-tax contribution expected to emerge
from the operation of the Closed Block is not affected by the aggregate actual
experience of the Closed Block assets and the Closed Block Business subsequent
to the Plan Effective Date, except in the unlikely event that the Closed Block
assets and the actual experience of the Closed Block Business subsequent to the
Plan Effective Date are not sufficient to pay the guaranteed benefits on the
Closed Block Policies, in which case the Company will be required to fund any
such deficiency from its general account assets outside of the Closed Block.
 
     The results of the Closed Block are presented as a single line item in the
Company's statements of income entitled, "Contribution from the Closed Block".
Prior to the establishment of the Closed Block the results of the assets and
policies comprising the Closed Block were reported in various line items in the
Company's income statements, including: premiums, investment income, net
realized gains and losses on investments, benefits, amortization of deferred
policy acquisition costs, etc. In addition, all assets and liabilities allocated
to the Closed Block will be reported in the Company's balance sheet separately
under the captions "Closed Block assets" and "Closed Block liabilities",
respectively. Accordingly, certain line items in the Company's financial
statements subsequent to the establishment of the Closed Block reflect material
reductions in reported amounts, as compared to years prior to the establishment
of the Closed Block, while having no effect on net income.
 
     The pre-tax Contribution from the Closed Block includes only those
revenues, benefit payments, dividends, premium taxes, state guaranty fund
assessments, and investment expenses considered in funding the Closed Block.
However, many expenses associated with operating the Closed Block and
administering the policies included therein were excluded from and, accordingly,
are not funded in the Closed Block. These expenses are reported in the Company's
statement of operations, outside of the Contribution from the Closed Block,
consistent with how they are funded. Such expenses are reported in the separate
line items to which they apply based on the nature of such expenses. Federal
income taxes applicable to the Closed Block, which are funded in the Closed
Block, are reflected as a component of federal income tax expense in the
Company's statement of operations. Since many expenses related to the Closed
Block are funded outside

During the quarter certain adjustments were made to revise estimates made in
connection with the establishment of the Closed Block which resulted in a net
increase to the Closed Block deficit.
 
At March 31, 1999 and December 31, 1998, there were no adjustments in the value
of fixed maturity securities in the Closed Block deemed to be other than
temporary or fixed maturity securities which have been non-income producing for
the twelve months preceding such dates. At March 31, 1999 and December 31, 1998
the carrying value of mortgage loans in the Closed Block that were non-income
producing for the twelve months preceding such date, were $0.7 million and $0.5
million, respectively.

ITEM 2:
 
                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following discussion addresses the consolidated financial condition and
results of operations of the Company for the periods indicated. The discussion
of the Company's consolidated financial results of operations is based on the
results of the Closed Block for the three-month period ended March 31, 1999
combined on a line by line basis with the results of operations outside the
Closed Block for such period, as further discussed below. This discussion and
analysis of the Company's financial condition and results of operations should
be read in conjunction with the Company's unaudited interim condensed
consolidated financial statements and the related notes to the unaudited interim
condensed consolidated financial statements included elsewhere herein and the
Annual Report to Shareholders on Form 10-K.
 
     The MONY Group was incorporated on June 24, 1997, under the laws of
Delaware, as a wholly owned subsidiary of MONY. The MONY Group was formed for
the purpose of becoming the parent holding company of MONY pursuant to the Plan.
On November 16, 1998, the Plan was approved by the New York Superintendent of
Insurance and MONY converted from a mutual life insurance company to a stock
life insurance company and became a wholly owned subsidiary of the MONY Group.
In connection with the Plan, MONY established the Closed Block to fund the
guaranteed benefits and dividends of certain participating insurance policies
(see Note 6 to the Unaudited Interim Condensed Consolidated Financial
Statements) and eligible policyholders of MONY received either cash, policy
credits, or shares of common stock in the MONY Group in exchange for their
membership interests in MONY. Also, on November 16, 1998, the MONY Group
consummated an initial public offering (the "Offerings") of approximately 12.9
million shares of its common stock (see "Liquidity and Capital Resources") and
MONY changed its name to MONY Life. The shares of common stock issued in the
Offerings are in addition to approximately 34.3 million shares of common stock
of the MONY Group distributed to the aforementioned eligible policyholders. The
MONY Group has no other operations or subsidiaries.
 
     MONY's conversion to a stock life insurance company and the establishment
of the Closed Block have significantly affected the presentation of the
consolidated financial statements of the Company. The most significant effects
are as follows:
 
      (i) the actual results of the Closed Block's operations are reflected as a
          single line item in the Company's statements of income, entitled
          "Contribution from the Closed Block", whereas, prior to the
          establishment of the Closed Block the results of its operations were
          reported in various line items in the Company's income statement,
          including premiums, net investment income, net realized gains,
          benefits, amortization of deferred policy acquisition costs, etc.
 
      (ii) all assets and liabilities allocated to the Closed Block are reported
           separately in the Company's balance sheet under the captions "Closed
           Block assets" and "Closed Block liabilities", respectively, whereas
           prior to the establishment of the Closed Block such assets and
           liabilities were reported in various line items in the Company's
           balance sheet, including fixed maturity securities, mortgage loans on
           real estate, policy loans, deferred policy acquisition costs, etc.
 
     (iii) revenues and expenses reported in the income statement for the
           three-month period ended March 31, 1999 represent all revenues and
           associated expenses earned or incurred during such period, however in
           accordance with generally accepted accounting principles, actual
           "basic" and "diluted" per share amounts are presented only for
           periods subsequent to the effective date of the Plan.
 
     The pre-tax contribution from the Closed Block for the three-month period
ended March 31, 1999 was $10.5 million. The Closed Block includes only those
revenues, benefit payments, dividends and premium taxes considered in funding
the Closed Block and excludes many costs and expenses associated with operating
the Closed Block and administering the policies included therein. Since many
expenses related to the Closed Block were excluded from the calculation of the
Closed Block contribution, the contribution from the Closed Block does not
represent the actual profitability of the business in the Closed Block. As a
result, operating costs and expenses outside the Closed Block are
disproportionate to the business outside the Closed Block.
 
GROUP PENSION TRANSACTION
 
     Management expects that Group Pension Profits will decline in future
periods consistent with the continuing run-off of the underlying business until
they terminate as of December 31, 2002. For a description of the Group Pension
Transaction, the Group Pension Profits and certain summary financial information
relating thereto, refer to Note 4 of the unaudited interim condensed
consolidated financial statements included herein.
 
                             RESULTS OF OPERATIONS
 
     For comparability with prior periods, the table below presents the results
of operations of the Closed Block for the three-month period ended March 31,
1999 combined on a line by line basis with the results of operations outside the
Closed Block. In all other respects the financial information herein is
presented in accordance with GAAP unless

otherwise noted. Management's Discussion and Analysis, which follows this table,
addresses the results of operations of the Company on the aforementioned
combined basis unless otherwise noted.

</TABLE>
 
RESULTS OF OPERATIONS --
 
 Consolidated -- For the Three-Month Period Ended March 31, 1999 Compared to the
 Three-Month Period Ended March 31, 1998
 
     Premium revenue was $169.7 million for the three-month period ended March
31, 1999, a decrease of $6.7 million, or 3.8% from $176.4 million reported in
the comparable prior year period. The decrease resulted primarily from: (i)
lower renewal premiums on traditional life business of $12.9 million resulting
from the decrease in such in-force business; and (ii) lower premiums of $2.9
million from certain runoff group pension business which was not included in the
Group Pension Transaction, offset by, (iii) an increase in premiums of $3.3
million resulting from the consolidation of the results of Sagamore Financial
Corporation ("Sagamore") which was acquired December 31, 1998, (see Notes to
Unaudited Interim Condensed Financial Statements included elsewhere herein) and
(iv) higher new premiums of approximately $5.6 million. Management believes that
the overall decrease in premium revenues is consistent with trends in the
industry, particularly the continuing shift by consumers from traditional
protection products to asset accumulation and retirement income products.
 
     Universal life and investment-type product policy fees were $45.4 million
for the three-month period ended March 31, 1999, an increase of $8.8 million or
24.0% from $36.6 million reported in the comparable prior year period ended
March 31, 1998. This increase was primarily the result of fees earned by
Sagamore of $4.9 million, higher fees relating to the Company's flexible premium
deferred annuity ("FPVA") business and variable universal life ("VUL") business
of $2.2 million and $2.5 million, respectively. The Company reported total fees
from its FPVA business during the period of $17.2 million, as compared to $15.0
million reported for the comparable prior year period. The increase in FPVA fees
resulted from an increase in the average FPVA account value of $0.2 billion
during the three-month period ended March 31, 1999 to $4.3 billion, as compared
to $4.1 billion for the comparable prior year period. See "Accumulation Products
Segment". FPVA sales were $104.1 million in the first quarter of 1999, as
compared to $157.0 million in the first quarter of 1998. Management believes
that delays in state regulatory approvals of new products introduced by the
Company in connection with its reorganization in November 1998 contributed to
the decline. The Company reported total fees from its VUL business during the
period of $8.3 million, as compared to $5.8 million reported for the comparable
period in the prior year. This increase is primarily due to higher cost of
insurance charges of approximately $1.6 million consistent with the in-force
growth of such business.
 
                                       19
<PAGE>   20
 
     Net investment income was $188.1 million for the three month period ended
March 31, 1999, an increase of $5.9 million, or 3.2%, from $182.2 million
reported for the comparable prior year period. Lower interest rates for the
three month period ended March 31, 1999 compared to the three month period ended
March 31, 1998 resulted in lower investment income of approximately $5.5
million, while an increase in the Company's average total invested assets
between the periods of approximately $429.8 million, and changes in the mix of
invested assets from lower yielding real estate to higher yielding fixed
maturity securities resulted in an offsetting increase in investment income of
approximately $11.5 million. The effect of investing new money of approximately
$2.5 billion (including the proceeds from prepayments, sales and maturities of
its invested assets, as well as net cash flow from operating activities),
reduced the total yield on invested assets by approximately six basis points for
the three month period ended March 31, 1999 compared to the three month period
ended March 31, 1998. Average total invested assets for the three month period
ended March 31, 1999 increased as compared to the comparable prior year period,
primarily as a result of IPO proceeds received and gains from sales of real
estate in 1998, acquisition of USFL, and positive cash flow from operations and
investing activities between the periods. For the three month period ended March
31, 1999, the Company's average investment in fixed maturity securities (before
cumulative unrealized gains or losses), cash and short term securities, and
equity securities increased by approximately $649.3 million, $147.4 million, and
$95.8 million, respectively, while real estate and other invested assets (mostly
real estate partnerships) decreased by approximately $460.3 million and $34.0
million, respectively. As of March 31, 1999, invested assets were $10,948.9
million (including cumulative unrealized gains of $124.2 million for fixed
maturity securities) compared to $10,614.9 million (including cumulative
unrealized gains of $189.9 million for fixed maturity securities) for the prior
year period. At March 31, 1999, fixed maturity securities, mortgage loans and
real estate represented approximately 61.2%, 13.6% and 5.9%, respectively, of
total invested assets, as compared to 58.0%, 13.8% and 10.2%, respectively, at
March 31, 1998. The annualized yield on the Company's invested assets before and
after realized gains/(losses) on investments was 6.9% and 8.1%, respectively,
for the three month period ended March 31, 1999, as compared to 7.0% and 9.2%,
respectively, for the three month period ended March 31, 1998.
 
     Net realized capital gains were $33.2 million for the three-month period
ended March 31, 1999, a decrease of $24.3 million, or 42.3%, from $57.5 million
for the comparable prior year period. The decrease is due primarily to lower
gains on sales of real estate and real estate partnership equities of $34.4
million, higher valuation allowances for real estate added to the held for sale
category of $6.3 million, higher provisions for other-than-temporary impairment
of equity securities of $1.5 million, offset with higher gains on sales of
equity securities of $15.6 million, and lower provisions for other-than-
temporary impairment of fixed maturities of $2.7 million. Gains on the sale of
real estate and real estate partnerships were $2.4 million for the three-month
period ended March 31, 1999, compared to $36.8 million for the comparable prior
year period. Provisions for valuation allowances on real estate held for sale
were $5.9 million for the three-month period ended March 31, 1999, compared to a
decrease in such valuation allowances of $0.4 million for the comparable prior
year period. Provisions for other-than-temporary impairment of equity securities
were $1.5 million for the three-month period ended March 31, 1999, compared to
$0 for the comparable prior year period. Gains on sales of equity securities
were $33.1 million for the three-month period ended March 31, 1999, compared to
$17.5 million for the comparable prior year period. There were no provisions for
other-than-temporary impairment of fixed maturities for the first quarter of
1999, compared to $2.7 million in the first quarter of 1998.
 
     Group Pension Profits were $14.3 million for the three-month period ended
March 31, 1999, an increase of $4.7 million, or 49.0%, from $9.6 million
reported in the comparable prior year period. Group Pension Profits consisted of
$9.1 million of Group Pension Payments, and a decrease of $5.2 million in
valuation allowances to reflect higher collateral valuations and more favorable
loan loss experience. In the comparable prior year period, Group Pension Profits
consisted of $8.8 million of Group Pension Payments and $0.8 million relating to
a decrease in the aforementioned valuation allowances. See "Group Pension
Transaction."
 
     Other income (which consists primarily of fees earned by the Company's
mutual fund management, broker-dealer, and insurance brokerage operations, as
well as revenues from interest on deposits held under financial reinsurance
arrangements, certain other asset management fees, and other miscellaneous
revenues) was $42.4 million for the three-month period ended March 31, 1999, an
increase of $7.3 million, or 20.8%, as compared to $35.1 million reported in the
comparable prior year period. The increase was primarily the result of higher
fees of $4.8 million earned by the Company's mutual fund management operations
and an increase of $4.0 million earned by the Company's broker-dealer operations
offset by a $1.7 million decrease in reinsurance expense allowances relating to
disability income insurance business. During the three-month period ended March
31, 1999, the Company's broker-dealer operations reported commission earnings of
$13.2 million, as compared to $9.3 million reported in the comparable prior year
period. Also, during the first quarter of 1999, the Company's mutual fund
management operations reported $18.4 million in fees from advisory, underwriting
and distribution services, as compared to $13.6 million reported in the
comparable prior year period, as assets under management increased to
approximately $7.3 billion from $6.3 billion at March 31, 1999 and 1998,
respectively.
 
     Benefits to policyholders were $186.9 million for the three-month period
ended March 31, 1999, an increase of $0.4 million, or 0.2%, as compared to
$186.5 million reported in the comparable prior year period. The increase
primarily due to $4.5 million of benefits from Sagamore, an increase of $0.8
million relating to benefits paid on supplementary contracts, offset by a $5.7
million decrease in the runoff businesses (group insurance and group pension
business) included in the other segment. See discussion and analysis of the
results of the Other segment below.
 
                                       20
<PAGE>   21
 
     Interest credited to policyholder account balances was $30.1 million for
the three-month period ended March 31, 1999, a decrease of $0.2 million, or
0.7%, as compared to $30.3 million reported in the comparable prior year period.
The decrease primarily resulted from lower interest crediting during the
three-month period ended March 31, 1999 as compared to the comparable prior year
period of $1.4 million and $1.2 million relating to single premium deferred
annuities ("SPDA") and annuitized pension business, respectively, offset by an
increase in interest credited of $1.1 million relating to the consolidation of
Sagamore.
 
     Amortization of deferred policy acquisition costs was $34.7 million for the
three-month period ended March 31, 1999, an increase of $1.8 million, or 5.5%,
as compared to $32.9 million reported in the comparable prior year period. The
increase primarily resulted from higher amortization of approximately $1.3
million and $1.5 million relating to higher earnings in the Company's FPVA and
VUL product lines, respectively, offset by a decrease in amortization of
approximately $1.1 million relating to the Company's universal life business
resulting from higher death claims during the three-month period ended March 31,
1999 as compared to the comparable prior year period.
 
     Other operating costs and expenses were $107.0 million for the three-month
period ended March 31, 1999, a decrease of $2.4 million, or 2.2%, as compared to
$109.4 million reported in the comparable prior year period. The decrease
primarily consisted of lower expenses of $10.3 million with respect to certain
of the Company's benefit plans, lower year 2000 costs of $1.6 million, lower
compensation costs of $4.0 million, and a $1.2 million recurring savings
resulting from a change in benefits under the Company's pension plan offset by
$4.0 million of higher sub-advisory fees and other expenses incurred by the
Company's mutual fund management operations, $1.9 million of higher commissions
and other expenses incurred by the Company's broker-dealer operations, $3.3
million resulting from the consolidation of Sagamore's results, and $3.0 million
of non-recurring charges related to the consolidation and closing of certain
agency offices and resultant employee reductions.
 
     Dividends to policyholders of $63.6 million for the three-month period
ended March 31, 1999 increased $9.0 million, or 16.5% from $54.6 million
reported in the comparable prior year period. Substantially all of the increase
relates to the accrual of an additional dividend liability in the Closed Block
reflecting results for the quarter that were more favorable than assumed in the
funding of the Closed Block. As further discussed in Note 6 to the Unaudited
Interim Condensed Consolidated Financial Statements included elsewhere herein,
all the assets in the Closed Block inure solely to the benefit of the Closed
Block policyholders, and to the extent that the results of the Closed Block are
more favorable than assumed in establishing the Closed Block, total dividends
paid to Close Block policyholders will be increased accordingly. Only the excess
of the Closed Block liabilities over the Closed Block assets at the date of the
establishment of the Closed Block will be recognized in the Company's income
over the period the policies and contracts in the Closed Block remain in force.

RESULTS OF OPERATIONS --
 
  Protection Segment -- For the Three-Month Period Ended March 31, 1999 Compared
  to the Three-Month Period Ended March 31, 1998
 
     Premium revenue was $166.9 million for the three-month period ended March
31, 1999, a decrease of $3.5 million, or 2.1%, from $170.4 million reported in
the comparable prior year period. The decrease resulted primarily from lower
renewal premiums on traditional life business of $12.9 million resulting from
the decrease in such in-force business, offset by an increase in premiums of
$3.3 million resulting from the consolidation of the results of Sagamore
Financial Corporation and higher new premiums of approximately $5.6 million.
Management believes that the overall decrease in premium revenues is consistent
with trends in the industry, particularly the continuing shift by consumers from
traditional protection products to asset accumulation and retirement income
products.
 
     Universal life policy fees were $27.8 million for the three-month period
ended March 31, 1999, an increase of $6.8 million or 32.4% from $21.0 million
reported in the comparable prior year period. This increase was primarily the
result of higher fees relating to the Company's VUL business of $2.5 million.
The Company reported total fees from its VUL business of $8.3 million for the
three-month period ended March 31, 1999, as compared to $5.8 million reported
for the comparable prior year period. This increase is primarily due to higher
cost of insurance charges of approximately $1.6 million consistent with the
in-force growth of such business.
 
     Net investment income and net realized gains on investments were $179.6
million for the three-month period ended March 31, 1999, a decrease of $5.0
million, or 2.7%, from $184.6 million reported in the comparable prior year
period. The decrease was primarily due to lower gains on sales of real estate
and real estate partnerships equities.
 
     Group Pension Profits were $14.3 million for the three-month period ended
March 31, 1999, an increase of $4.7 million, or 49.0%, from $9.6 million
reported in the comparable prior year period. Group Pension Profits consisted of
$9.1 million of Group Pension Payments, and a decrease of $5.2 million in
valuation allowances to reflect higher collateral valuations and more favorable
loan loss experience. In the comparable prior year period, Group Pension Profits
consisted of $8.8 million of Group Pension Payments and $0.8 million relating to
a decrease in the aforementioned valuation allowances. See "Group Pension
Transaction."
 
     Other income was $3.7 million for the three-month period ended March 31,
1999, a decrease of $1.8 million or 32.7%, as compared to $5.5 million reported
in the comparable prior year period. The decrease was primarily the result of a
$1.5 million decrease in reinsurance expense allowances related to disability
income insurance business.
 
     Benefits to policyholders were $176.8 million for the three-month period
ended March 31, 1999, an increase of $4.1 million, or 2.4%, as compared to
$172.7 million reported in the comparable prior year period. The increase
primarily due to $4.5 million of benefits from Sagamore.
 
     Interest credited to policyholder account balances was $12.5 million for
the three-month period ended March 31, 1999, an increase of $1.5 million, or
13.6%, as compared to $11.0 million reported in the comparable prior year
period. This increase was primarily due to the consolidation of Sagamore's
results, which included $1.1 million of interest credited.
 
     Amortization of deferred policy acquisition costs ("DAC") was $27.0 million
for the three-month period ended March 31, 1999, an increase of $0.9 million, or
3.4%, as compared to $26.1 million reported in the comparable prior year period.
The increase primarily resulted from higher amortization of approximately $1.5
million relating to higher earnings in the Company's VUL product line, offset by
a decrease in amortization of $1.1 million relating to the Company's universal
life business.
 
     Other operating costs and expenses were $63.3 million for the three-month
period ended March 31, 1999, a decrease of $10.1 million, or 13.8%, as compared
to $73.4 million reported in the comparable prior year period. The decrease
primarily consists of a $9.9 million decrease with respect to certain of the
Company's benefit plan, lower Year 2000 costs of $1.6 million, lower
compensation costs of $3.6 million and a $1.2 million recurring savings
resulting from a change in benefits under the Company's pension plan, offset by
$3.3 million resulting from the consolidation of Sagamore and $3.0 million
related to the consolidation and closing of certain agency offices and resultant
employee reductions.
 
     Dividends to policyholders of $62.9 million for the three-month period
ended March 31, 1999 increased $9.0 million, or 16.7% from $53.9 million
reported in the comparable prior year period. Substantially all of the increase
relates to the accrual of an additional dividend liability in the Closed Block
reflecting results for the quarter that were more favorable than assumed in the
funding of the Closed Block. As further discussed in Note 6 to the Unaudited
Interim Condensed Consolidated Financial Statements included elsewhere herein,
all the assets in the Closed Block inure solely to the benefit of the Closed
Block policyholders, and to the extent that the results of the Closed Block are
more favorable than assumed in establishing the Closed Block, total dividends
paid to Close Block policyholders will be increased accordingly. Only the excess
of the Closed Block liabilities over the Closed Block assets at the date of the
establishment of the Closed Block will be recognized in the Company's income
over the period the policies and contracts in the Closed Block remain in force.

  Accumulation Segment -- For the Three-Month Period Ended March 31, 1999
  Compared to the Three-Month Period Ended March 31, 1998
 
     Investment-type product policy fees were $17.2 million for the three-month
period ended March 31, 1999, an increase of $2.2 million, or 14.7%, from $15.0
million reported in the comparable period ended March 31, 1998. This increase
was the result of higher fees relating to the Company's FPVA business of $2.2
million. The Company reported total fees from its FPVA business during the
period of $17.2 million, as compared to $15.0 million reported for the
comparable prior year period. The increase in FPVA fees resulted from an
increase in the average FPVA account value of $0.2 billion during the
three-month period ended March 31, 1999 to $4.3 billion, as compared to $4.1
billion for the comparable prior year period. FPVA sales were $104.1 million in
the first quarter of 1999, as compared to $157.0 million in the first quarter of
1998. Management believes that delays in state regulatory approvals of new
products introduced by the Company in connection with its reorganization in
November 1998 contributed to the decline.
 
     Net investment income and net realized gains on investments were $28.9
million for the three-month period ended March 31, 1999, a decrease of $7.3
million, or 20.2%, from $36.2 million reported in the comparable period ended
March 31, 1998. The decrease was primarily due to lower gains on sales of real
estate and real estate partnership equities.
 
     Other income (which consists primarily of fees earned by the Company's
mutual fund management and supplementary contracts) was $20.9 million for the
three-month period ended March 31, 1999, an increase of $5.6 million, or 36.6%,
as compared to $15.3 million reported in the comparable prior year period. The
increase was primarily the result of higher fees earned by the Company's mutual
fund management operations of $4.8 million.
 
     Benefits to policyholders were $4.3 million for the three-month period
ended March 31, 1999, an increase of $0.3 million, or 7.5%, as compared to $4.0
million reported in the comparable prior year period. The increase is primarily
due to an increase in benefits paid on supplementary contracts.
 
     Interest credited to policyholder account balances was $14.0 million for
the three-month period ended March 31, 1999, a decrease of $2.1 million, or
13.0%, as compared to $16.1 million reported in the comparable prior year
period. The decrease primarily resulted from lower interest crediting during the
three month period ended March 31, 1999 as compared to the comparable prior year
period of $1.4 million and $1.2 million relating to SPDA products and annuitized
pension business, respectively.
 
     Amortization of DAC was $7.7 million for the three-month period ended March
31, 1999, an increase of $0.9 million, or 13.2%, as compared to $6.8 million
reported in the comparable prior year period. The increase is primarily the
result of higher amortization relating to higher earnings in the Company's FPVA
product line.
 
     Other operating costs and expenses were $23.4 million for the three-month
period ended March 31, 1999, an increase of $4.8 million, or 25.8%, as compared
to $18.6 million reported in the comparable prior year period. The increase
 
                                       23

primarily consists of higher sub-advisory fees and commissions incurred by the
Company's mutual fund management operations of approximately $4.0 million.

  Other Products Segment -- For the Three-Month Period Ended March 31, 1999
  Compared to the Three-Month Period Ended March 31, 1998
 
     Premium revenue was $2.4 million for the three-month period ended March 31,
1999, a decrease of $3.1 million, or 56.4%, from $5.5 million reported in the
comparable period ended March 31, 1998. The decrease primarily relates to a
decrease of $2.9 million in premiums on certain runoff group pension business
which was not included in the Group Pension Transaction.
 
     Net investment income and net realized gains on investments were $10.9
million for the three-month period ended March 31, 1999, a decrease of $7.6
million, or 41.1%, from $18.5 million reported in the comparable period ended
March 31, 1998. The decrease was due to lower gains of sales on real estate and
real estate partnership equities.
 
     Other income was $16.8 million for the three-month period ended March 31,
1999, an increase of $4.0 million, or 31.3%, as compared to $12.8 million
reported in the comparable prior year period. The increase was primarily the
result of higher commissions earned by the Company's broker-dealer operations.
 
     Benefits to policyholders were $3.5 million for the three-month period
ended March 31, 1999, a decrease of $5.7 million, or 62.0%, as compared to $9.2
million reported in the comparable prior year period. The decrease was due to
decreases in group insurance and group pension business of $2.6 million and $3.1
million, respectively.
 
     Other operating costs and expenses were $20.3 million for the three-month
period ended March 31, 1999, an increase of $2.9 million, or 16.7%, as compared
to $17.4 million reported in the comparable prior year period. The increase
primarily consists of higher commission and other expenses incurred by the
Company's broker-dealer operations of $1.9 million.

LIQUIDITY AND CAPITAL RESOURCES
 
  Holding Company
 
     The MONY Group's cash flow consists of investment income from its invested
assets, as well as dividends from MONY Life, if declared and paid, offset by
expenses incurred in connection with the administration of the MONY Group's
affairs, including salaries and other expenses. As a holding company, the MONY
Group's ability to meet its cash requirements and pay dividends on its common
stock substantially depends upon the receipt of dividends and other payments
from MONY Life. The payment of dividends from MONY Life to MONY Group is
regulated under state insurance law. Under the New York Insurance Law, MONY Life
will be permitted to pay shareholder dividends and other payments to MONY Group
only if it files notice of its intention to declare such a dividend and the
amount thereof with the New York Superintendent and the New York Superintendent
does not disapprove the distribution. Under the New York Insurance Law, the New
York Superintendent has broad discretion in determining whether the financial
condition of a stock life insurance company would support the payment of
dividends to its shareholders. The New York Insurance Department has established
informal guidelines for the New York Superintendent's determinations that focus
on, among other things, overall financial condition and profitability under
statutory accounting practices. Management believes these guidelines may limit
the ability of MONY Life to pay dividends to the MONY Group. There can be no
assurance that MONY Life will have statutory earnings to support the payment of
dividends to the MONY Group in an amount sufficient to fund its cash
requirements and pay cash dividends. In addition, state insurance laws contain
similar restrictions on the ability of the life insurance subsidiaries to pay
dividends to MONY Life. There can be no assurance that state insurance laws will
in the future permit the payment by the life insurance subsidiaries to MONY Life
in an amount sufficient to support the ability of MONY Life to pay dividends to
the MONY Group.
 
     On December 30, 1997, the Investors entered into the Investment Agreement
with MONY, pursuant to which among other things the Investors purchased, for
$115.0 million (the "Consideration"), MONY Notes with an aggregate principal
amount equal to the Consideration. Pursuant to the terms of the Investment
Agreement, the Investors may elect to exchange the MONY Notes for Holding
Company Subordinated Notes. If such exchange occurs, the MONY Group will hold
one or more Intercompany Surplus Notes in an aggregate principal amount equal to
the principal amount of the Holding Company Subordinated Notes.
 
     If the Holding Company Subordinated Notes are issued, the MONY Group will
receive payments of principal and interest from MONY Life on the Intercompany
Surplus Notes. The Intercompany Surplus Notes will be in an aggregate principal
amount equal to the aggregate principal amount of the Holding Company
Subordinated Notes and bear interest at 9.50% per annum, which is payable
semiannually. Principal is payable at maturity. Payments of principal and
interest on the Intercompany Surplus Notes can only be made with the prior
approval of the New York Superintendent "whenever, in his judgment, the
financial condition of such insurer warrants". Such payments further may be made
only out of surplus funds, which are available for such payments under the New
York Insurance Law. There can be no assurance that MONY Life will obtain the
requisite approval for payments with respect to the Intercompany Surplus Notes,
or that surplus funds will be available for such payments.
 
     On February 23, 1999, the MONY Group's Board of Directors approved a
quarterly dividend of $0.10 per share. The dividend was paid on March 26, 1999
to shareholders of record as of March 8, 1999. The MONY Group expects to
continue paying quarterly dividends on its common stock of $0.10 per share
throughout 1999.
 
  Capitalization
 
     The Company's total capitalization, including short-term debt and excluding
accumulated comprehensive income, increased $44.4 million or 2.2%, to $2,045.0
million at March 31, 1999, as compared to $2,000.6 million at December 31, 1998.
The increase was primarily the result of net income of $46.0 million. The
Company's total debt to equity (excluding accumulated comprehensive income) and
total debt to total capitalization ratios decreased to 22.7% and 18.5% at March
31, 1999, respectively, from 23.1% and 18.8% at December 31, 1998, respectively.
 
  MONY Life
 
     MONY Life's cash inflows are provided mainly from life insurance premiums,
annuity considerations and deposit funds, investment income and maturities and
sales of invested assets. Cash outflows primarily relate to the liabilities
associated with its various life insurance and annuity products, dividends to
policyholders, operating expenses, income taxes, acquisitions of invested
assets, and principal and interest on its outstanding debt obligations. The life
insurance and annuity liabilities relate to the Company's obligation to make
benefit payments under its insurance and annuity contracts, as well as the need
to make payments in connection with policy surrenders, withdrawals and loans.
The Company develops an annual cash flow projection which shows expected asset
and liability cash flows on a monthly basis. At the end of each quarter actual
cash flows are compared to projections, projections for the balance of the year
are adjusted in light of the actual results, if appropriate, and investment
strategies are also changed, if appropriate. The quarterly cash flow reports
contain relevant information on all of the following: new product sales and
deposits versus projections, existing liability cash flow versus projections and
asset portfolio cash flow versus projections. An interest rate projection is a

lesser extent, changes in rate expectations will impact the changes in projected
asset and liability cash flows during the course of the year. When the Company
is formulating its cash flow projections it considers, among other things, its
expectations about sales of the Company's products, its expectations concerning
customer behavior in light of current and expected economic conditions, its
expectations concerning competitors and the general outlook for the economy and
interest rates.
 
     The events most likely to cause an adjustment in the Company's investment
policies are: (i) a significant change in its product mix, (ii) a significant
change in the outlook for either the economy in general or for interest rates in
particular and (iii) a significant reevaluation of the prospective risks and
returns of various asset classes.

(1) Includes $19.0 million of surrenders in the Closed Block, the proceeds from
    which remained with the Company to fund premiums on newly issued traditional
    life policies outside the Closed Block.
 
(2) Excludes approximately $106.0 million relating to surrenders associated with
    an exchange program offered by the Company wherein contractholders
    surrendered old FPVA contracts and reinvested the proceeds therefrom in a
    new enhanced FPVA product offered by the Company.
 
     The Company's principal sources of liquidity to meet cash outflows are its
portfolio of liquid assets and its net operating cash flow. During the
three-month period ended March 31, 1999, the net cash flow from operations
reported in the Company's consolidated cash flow statement was $64.4 million.
This amount excludes $14.1 million of cash flow relating to the Closed Block.
Total combined cash flow for the three-month period ended March 31, 1999
(including the Closed Block) was $78.5 million, a decrease of $15.2 million from
$93.7 million reported for the three-month period

ended March 31, 1998. The decrease primarily relates to lower Group Pension
Payments, lower premiums, and other miscellaneous items. The Company's liquid
assets include substantial U.S. Treasury holdings, short-term money market
investments and marketable long-term fixed maturity securities. Management
believes that the Company's sources of liquidity are adequate to meet its
anticipated needs. As of March 31, 1999, the Company had readily marketable
fixed maturity securities with a carrying value of $6,704.1 million (including
fixed maturities in the Closed Block), which were comprised of $3,757.5 million
public and $2,946.6 million private fixed maturity securities. At that date,
approximately 94.2% of the Company's fixed maturity securities were designated
in NAIC rating categories 1 and 2 (considered investment grade, with a rating of
"Baa" or higher by Moody's or "BBB" or higher by S&P). In addition, at March 31,
1999 the Company had cash and cash equivalents of $392.8 million.
 
     In addition, the Company maintains two bank line of credit facilities with
domestic banks aggregating $150.0 million, with scheduled renewal dates in
September 1999 and September 2003. Under these lines of credit, the Company is
required to maintain a certain statutory tangible net worth and debt to
capitalization ratio. The purpose of these facilities is to provide additional
liquidity for any unanticipated short-term cash needs the Company might
experience. The Company has not borrowed against these lines of credit since
their inception.
 
     At March 31, 1999, the Company had commitments to issue $40.8 million of
fixed rate agricultural loans with periodic interest rate reset dates. The
initial interest rates on such loans range from 6.75% to 7.80%. In addition, the
Company had commitments to issue $109.9 million of fixed rate commercial
mortgage loans with interest rates ranging from 6.88% to 8.09%. The Company also
had commitments outstanding to purchase $75.4 million of private fixed maturity
securities as of March 31, 1999 with interest rates ranging from 6.4% to 9.2%.
At March 31, 1999, the Company had commitments to contribute capital to its
equity partnership investments of $110.4 million.
 
     Of the $937.1 million of currently outstanding commercial mortgage loans in
the Company's investment portfolio at March 31, 1999, $109.6 million, $25.0
million, $77.3 million, and $91.6 million are scheduled to mature in 1999, 2000,
2001 and 2002, respectively.
 
     In 1994, the Company completed the sale of $125.0 million face amount of
its 11.25% Surplus Notes due August 15, 2024, which generated net proceeds of
$70.0 million after a discount of approximately 42.2% from the principal amount
payable at maturity and issuance expenses of approximately $2.3 million.
Following the discount accretion period, interest will begin to accrue on August
15, 1999; thereafter, interest is scheduled to be paid on February 15 and August
15 of each year, commencing February 15, 2000, at a rate of 11.25% per annum.
 
     To the extent that the MONY Notes are not exchanged for Holding Company
Subordinated Notes, they will remain as surplus notes of MONY having an interest
rate of 9.50%, payable semiannually in arrears on June 30 and December 31 in
each year.
 
     The Company has mortgage loans on certain of its real estate properties.
The interest rates on these loans range from 7.9% to 8.7%. Maturities range from
June 2000 to July 2009. Interest expense on mortgage loans was $1.5 million and
$2.9 million for the three-month periods ended March 31, 1999 and 1998,
respectively.
 
     During 1989, the Company entered into a transaction which is accounted for
as a financing arrangement involving certain real estate properties held for
investment. Pursuant to the terms of the agreement, the Company effectively
pledged the real estate properties as collateral for a loan of approximately
$35.0 million bearing simple interest at a rate of 8% per annum. Interest is
cumulative. Periodic interest payments are not required. All principal and
interest are effectively due at the maturity of the obligation (March 30, 2000)
which is subject to extension at the option of the creditor. However, interest
may be paid periodically subject to available cash flow from the real estate
properties. At March 31, 1999 and December 31, 1998, the outstanding balance of
the obligation including accrued interest was $43.0 million and $42.4 million,
respectively. Interest expense on the obligation of $0.8 million and $0.8
million for the three-month periods ended March 31, 1999 and 1998, respectively,
is reflected in other operating costs and expenses.
 
     In 1988, the Company financed one of its real estate properties under a
sale/leaseback arrangement. The facility was sold for $66.0 million, $56.0
million of which was in the form of an interest bearing note receivable and
$10.0 million in cash. The note is due January 1, 2009. The transaction is
accounted for as a financing. Accordingly, the facility remains on the Company's
books and continues to be depreciated. An obligation representing the total
proceeds on the sale was recorded by the Company at the effective date of the
transaction, and is reduced based on payments under the lease. The lease has a
term of 20 years beginning December 21, 1988 and requires minimum annual rental
payments of $7.1 million in 1999, $7.3 million in 2000, $7.4 million in 2001,
$7.6 million in 2002, $7.7 million in 2003, and $41.0 million thereafter. The
Company has the option to renew the lease at the end of the lease term.
 
     At March 31, 1999, aggregate maturities of long-term debt based on required
remaining principal payments for 1999 and the succeeding four years are $1.6
million, $54.4 million, $35.9 million, $0.5 million and $0.5 million,
respectively, and $247.6 million thereafter.
 
     Aggregate contractual debt service payments on the Company's debt at March
31, 1999, for the remainder of 1999 and the succeeding four years are $15.4
million, $84.6 million, $63.5 million, $25.6 million and $25.7 million,
respectively and $640.8 million thereafter.

     Among the assets allocated to the Closed Block are the Series A Notes. MONY
Life has undertaken to reimburse the Closed Block from its general account
assets outside the Closed Block for any reduction in principal payments on the
Series A Notes pursuant to the terms thereof, as described in "-- The Group
Pension Transaction".
 
     The NAIC established RBC requirements to help state regulators monitor and
safeguard life insurers' financial strength by identifying those companies that
may be inadequately capitalized. The RBC guidelines provide a method to measure
the adjusted capital (statutory-basis capital and surplus plus the Asset
Valuation Reserve and other adjustments) that a life insurance company should
have for regulatory purposes, taking into consideration the risk characteristics
of such company's investments and products. A life insurance company's RBC ratio
will vary over time depending upon many factors, including its earnings, the
nature, mix and credit quality of its investment portfolio and the nature and
volume of the products that it sells.
 
     While the RBC guidelines are intended to be a regulatory tool only, and are
not intended as a means to rank insurers generally, comparisons of RBC ratios of
life insurers have become generally available. The adjusted RBC capital ratios
of all the Company's insurance subsidiaries at March 31, 1999 and December 31,
1998 were in excess of the minimum required RBC.
 
YEAR 2000
 
  State of Readiness
 
     In 1996, the Company initiated a formal Year 2000 Project (the "Project")
to resolve the Year 2000 issue. The scope of the Project was identified, and
funding was established. In early 1997, the Company retained Command Systems,
Inc., and Keane, Inc. to assist in bringing the Company's computer and
information systems into Year 2000 compliance. The Company's overall goal for
information technology ("IT") related items was to have business-critical
hardware and software compliant by December 31, 1998, with additional testing
and enterprise end-to-end testing occurring in 1999. The Company has also
retained a consulting firm to assist in the evaluation of Year 2000 issues
affecting the Company's non-IT systems in facilities and equipment which may
contain date logic in embedded chips. The Company's overall goal is to have
these non-IT systems compliant by mid-1999.
 
     The scope of the Company's Project includes: ensuring the compliance of all
applications, operating systems and hardware on mainframe, PC and LAN platforms;
ensuring the compliance of voice and data network software and hardware;
addressing issues related to non-IT systems in buildings, facilities and
equipment which may contain date logic in embedded chips; and addressing the
compliance of key vendors and other third parties.
 
     The phases of the Project are (i) inventorying Year 2000 items and
assigning priorities; (ii) assessing the Year 2000 compliance of items; (iii)
remediating or replacing items that are determined not to be Year 2000
compliant; (iv) testing items for Year 2000 compliance; and (v) designing and
implementing Year 2000 contingency and business continuity plans. To determine
that all IT systems (whether internally developed or purchased) are Year 2000
compliant, each system is tested using a standard testing methodology which
includes unit testing, baseline testing, and future date testing. Future date
testing includes critical dates near the end of 1999 and into the year 2000,
including leap year testing.
 
     The inventory and assessment phases of the Project were completed prior to
mid 1998. At March 31, 1999, all of the Company's application systems had been
remediated and current date tested. In addition, approximately 98% of the
Company's applications had been future date tested, with future date testing for
the remaining 2% scheduled for completion by mid-1999. Newly acquired
applications and new releases of software packages will be tested in 1999 as
they are implemented.
 
     In late 1998 and early 1999, the Company contracted with a consulting firm
to perform an Independent Validation and Verification ("IV&V") of the Year 2000
remediation of selected critical applications. The results of the IV&V indicated
that the Company's remediation and testing processes were highly effective and
had achieved a high level of compliance.
 
     Approximately 90% of the operating systems, systems software, and hardware
for mainframe, PC and LAN platforms are deemed compliant based on information
supplied by vendors verbally, in writing, or on the vendor's Internet site.
Essentially all critical hardware and software was compliant and tested by
December 31, 1998. The remaining items will be resolved and tested by mid 1999.
Ongoing testing for Year 2000 compliance is continuing in 1999 as applications,
systems software and hardware is upgraded or replaced. Approximately 50% of
critical non-IT systems had been remediated as of March 31, 1999, and ongoing
testing for year 2000 compliance will continue through 1999.
 
     As part of the Project, significant service and information providers,
external vendors, suppliers, and other third parties (including
telecommunication, electrical, security, and HVAC systems), that are believed to
be critical to business operations after January 1, 2000, have been identified
and contacted. Procedures are being undertaken to ascertain with reasonable
certainty their current and reasonably anticipated states of Year 2000 readiness
through questionnaires, compliance letters, interviews, on-site visits, and
other available means.

  Costs
 
     The estimated total cost of the Year 2000 Project is approximately $26
million. The total amount expended on the Project through March 31, 1999 was $23
million, which includes $16 million for external vendor costs, and $7 million
for internal costs. The future cost of completing the Year 2000 Project is
estimated to be approximately $3 million, which includes $1 million for external
vendor costs, and $2 million for internal costs; the future Project cost will be
funded through operating cash flows. These amounts also include costs associated
with the development of contingency plans.
 
  Risks
 
     The Company believes that completed and planned modifications and
conversions of its internal systems and equipment will allow it to be Year 2000
compliant in a timely manner. There can be no assurance, however, that the
Company's internal systems or equipment will be entirely error-free, or those
external parties on which the Company relies will be Year 2000 compliant in a
timely manner, or that the Company's or external parties' contingency plans will
mitigate sufficiently the effects of any noncompliance. Based upon currently
available information and considering the Company's Year 2000 Project status,
management believes that the most reasonably likely worst case scenario would be
short-term interruptions to Company business operations. However, Year 2000
related failures in the Company's systems or equipment and/or failure of
external parties to achieve Year 2000 compliance could have a material adverse
effect on the Company's consolidated financial position and results of its
operations.
 
  Contingency Plans
 
     The Company has retained outside consultants to assist in the development
of Business Continuity Plans, which include identification of third party
service providers, information systems, equipment, facilities and other items
which are mission-critical to the operation of the business. In conjunction with
this effort, the Company is developing a Year 2000 Contingency Plan (the
"Contingency Plan") to address failures due to the Year 2000 problem of third
parties and other items, which are critical to the ongoing operation of the
business. The Contingency Plan provides alternate means of processing critical
work and services as well as a methodology for selection and retention of
alternate service providers, vendors, and suppliers if necessary. The scheduled
date for completion of the Contingency Plan is mid-1999. The Company believes
that due to the pervasive and evolving nature of potential Year 2000 issues, the
contingency planning process is an ongoing one that will require further
modifications as the Company obtains additional information regarding the status
of third party Year 2000 readiness.

                                  INVESTMENTS
 
     On the effective date of the Plan, the Company's invested assets were
allocated between the Closed Block and operations outside the Closed Block. In
view of the similar asset quality characteristics of the major asset categories
in the two portfolios, the invested assets in the Closed Block have been
combined with the Company's invested assets outside the Closed Block for
purposes of the following discussion and analysis. In addition, the following
discussion excludes invested assets transferred in the Group Pension
Transaction. Accordingly, this discussion should be read in conjunction with the
summary financial information regarding assets transferred in the Group Pension
Transaction presented in Note 4 to the Unaudited Interim Condensed Consolidated
Financial Statements.
 
     The yield on general account invested assets (including net realized gains
and losses on investments) was 8.1% and 9.2% for the three-month periods ended
March 31, 1999 and 1998, respectively.
 
     The following table illustrates the yields on average assets for each of
the components of the Company's investment portfolio for the three-month periods

(1) Yields are based on quarterly average asset carrying values, excluding
    unrealized gains (losses) in the fixed maturity asset category.
 
(2) Including net unrealized gains and losses in the determination of the total
    yield on equity securities for the three-month periods ended March 31, 1999
    and 1998 would have resulted in a total yield of 21.9% and 31.2%,
    respectively, which would have resulted in a total return on invested assets
    of 7.4% and 9.2% for the aforementioned periods, respectively.
 
(3) Equity real estate income is shown net of operating expenses, depreciation
    and minority interest.
 
(4) Excludes amounts referred to in (6) below.
 
(5) Total investment income includes non-cash income from amortization,
    payment-in-kind distributions and undistributed equity earnings of $15.0
    million and $9.6 million for the three-months ended March 31, 1999 and 1998,
    respectively. In addition, real estate investment income is shown net of
    depreciation of $3.6 million and $7.2 million for the aforementioned
    periods, respectively.
 
(6) Includes mortgage servicing fee and other miscellaneous fee income of
    approximately $1.2 million and $0.8 million for the three-months ended March
    31, 1999 and 1998, respectively.
 
FIXED MATURITIES
 
     Fixed maturities consist of publicly traded debt securities, privately
placed debt securities and small amounts of redeemable preferred stock, and
represented 61.2% and 61.0% of total invested assets at March 31, 1999 and
December 31, 1998, respectively.
 
     The Securities Valuation Office of the NAIC evaluates the bond investments
of insurers for regulatory reporting purposes and assigns securities to one of
six investment categories called "NAIC Designations". The NAIC Designations
closely mirror the Nationally Recognized Securities Rating Organizations' credit
ratings for marketable bonds. NAIC Designations 1 and 2 include bonds considered
investment grade ("Baa" or higher by Moody's, or "BBB" or higher by S&P) by such
rating organizations. NAIC Designations 3 through 6 are referred to as below
investment grade ("Ba" or lower by Moody's, or "BB" or lower by S&P).
 
     Of the Company's total portfolio of fixed maturity securities at March 31,
1999, 94.2% were investment grade and 5.8% were below-investment grade, where
56.2%, 38.0%, 5.0%, 0.4%, 0.4% and 0.0% had NAIC Designations of 1, 2, 3, 4, 5
and 6, respectively.
 
     The Company reviews all fixed maturity securities at least once each
quarter and identifies investments that management concludes require additional
monitoring. Among the criteria are: (i) violation of financial covenants,
 
                                       31
<PAGE>   32
 
(ii) public securities trading at a substantial discount as a result of specific
credit concerns, and (iii) other subjective factors relating to the issuer.
 
     The Company defines problem securities in the fixed maturity category as
securities (i) as to which principal and/or interest payments are in default or
are to be restructured pursuant to commenced negotiations or (ii) issued by a
company that went into bankruptcy subsequent to the acquisition of such
securities or (iii) are deemed to have other than temporary impairments to
value.
 
     The Company defines potential problem securities in the fixed maturity
category as securities that are deemed to be experiencing significant operating
problems or difficult industry conditions. Typically these credits are
experiencing or anticipating liquidity constraints, having difficulty meeting
projections/budgets and would most likely be considered a below investment grade
risk.
 
     The Company defines restructured securities in the fixed maturity category
as securities where a concession has been granted to the borrower related to the
borrower's financial difficulties that the Company would not have otherwise
considered. The Company restructures certain securities in instances where a
determination was made that greater economic value will be realized under the
new terms than through liquidation or other disposition. The terms of the
restructure generally involve some or all of the following characteristics: a
reduction in the interest rate, an extension of the maturity date and a partial
forgiveness of principal and/or interest.
 
     The following table sets forth the total carrying values of the Company's
fixed maturity portfolio, as well as its problem, potential problem and
restructured fixed maturities as of the dates indicated:

     At March 31, 1999, the Company's largest unaffiliated single concentration
of fixed maturities were $251.9 million of Federal Home Loan Mortgage
Corporation ("FHLMC") which represents 2.3% of total invested assets. The second
largest single concentration consists of $199.5 million of the Notes purchased
in connection with the Group Pension Transaction. These Notes represent
approximately 1.8% of total invested assets at March 31, 1999. No other
individual non-government issuer represents more than 0.5% of invested assets.
 
     The Company held approximately $1,178.9 million and $1,161.3 million of
mortgage-backed and asset-backed securities as of March 31, 1999 and December
31, 1998, respectively. Of such amounts, $447.6 million and $471.5 million, or
38.0% and 40.6%, respectively, represented agency-issued pass-through and
collateralized mortgage obligations ("CMOs") secured by Federal National
Mortgage Association, FHLMC, Government National Mortgage Association and
Canadian Housing Authority collateral. The balance of such amounts were
comprised of other types of mortgage-backed and asset-backed securities. The
Company believes that its active monitoring of its portfolio of mortgage-backed
securities and the limited extent of its holdings of more volatile types of
mortgage-backed securities mitigate the Company's exposure to losses from
prepayment risk associated with interest rate fluctuations for this portfolio.
At March 31, 1999 and December 31, 1998, 88.5% and 88.6%, respectively, of the
Company's mortgage-backed and asset-backed securities were assigned an NAIC
Designation of 1. In addition, the Company believes that it holds a relatively
low percentage of CMOs compared to other life insurance companies.

  Problem, Potential Problem and Restructured Commercial Mortgages
 
     Commercial mortgage loans are stated at their unpaid principal balances,
net of valuation allowances and writedowns for impairment. The Company provides
valuation allowances for commercial mortgage loans considered to be impaired.
Mortgage loans are considered impaired when, based on current information and
events, it is probable that the Company will be unable to collect all amounts
due according to the contractual terms of the loan agreement. When the Company
determines that a loan is impaired, a valuation allowance for loss is
established for the excess of the carrying value of the mortgage loan over its
estimated fair value. Estimated fair value is based on either the present value
of expected future cash flows discounted at the loan's original effective
interest rate, the loan's observable market price or the fair value of the
collateral. The provision for loss is reported as a realized loss on investment.
 
     The Company reviews its mortgage loan portfolio and analyzes the need for a
valuation allowance for any loan which is delinquent for 60 days or more, in
process of foreclosure, restructured, on "watchlist", or which currently has a
valuation allowance. Loans which are delinquent and loans in process of
foreclosure are categorized by the Company as "problem" loans. Loans with
valuation allowances, but which are not currently delinquent, and loans which
are on watchlist are categorized by the Company as "potential problem" loans.
Loans for which the original terms of the mortgages have been modified or for
which interest or principal payments have been deferred are categorized by the
Company as "restructured" loans.
 
     The following table presents the carrying amounts of problem, potential
problem and restructured commercial mortgage loans relative to the carrying
value of all commercial mortgage loans as of the dates indicated. The table also
presents the valuation allowances and writedowns recorded by the Company
relative to commercial mortgages defined as problem, potential problem and
restructured as of each of the dates indicated.

REAL ESTATE SALES
 
     In accordance with its ongoing strategy to strengthen the Company's
financial position, management expects to continue to selectively sell equity
real estate. Once management identifies a real estate property to be sold and
commences a plan for marketing the property, the property is classified as to be
disposed of and a valuation allowance is established and periodically revised,
if necessary, to adjust the carrying value of the property to reflect the lower
of its current carrying value or the fair value, less associated selling costs.
At March 31, 1999 and December 31, 1998, the carrying value of real estate to be
disposed of was $333.1 million and $312.9 million, respectively, or 3.1% and
2.8%, respectively of invested assets at such dates, respectively. The
aforementioned carrying values are net of valuation allowances of $35.5 million
and $30.6 million, respectively. In addition, the carrying value of real estate
to be disposed of at such dates is net of $107.2 million and $79.1 million of
impairment adjustments. For the three months ended March 31, 1999 and the year
ended December 31, 1998, such increases in valuation allowances aggregated $6.0
million and $6.7 million, respectively.

(1) Excludes sales of unconsolidated real estate joint ventures. Unconsolidated
    real estate joint venture interests are included in "Other invested assets".
    Gains from the sale of such interests were $0.0 million and $21.6 million
    for March 31, 1999 and 1998, respectively.
 
     Most of the proceeds from real estate sales have been invested in
investment grade bonds. This has served to make the overall asset portfolio
somewhat more sensitive to changes in interest rates. It has also served to
reduce exposure to an illiquid asset class, real estate, and increase exposure
to a more liquid asset class, investment grade public bonds.
 
EQUITY SECURITIES
 
     The Company's equity securities primarily consist of investments in common
stocks and limited partnership interests. Substantially all the common stocks
owned by the Company are publicly traded on national security exchanges.
 
     The following table presents the carrying values of the Company's
investments in common stocks and limited partnership interests at the dates
indicated. Included in common stocks at March 31, 1999 and December 31, 1998 are
$5.6 million, and $19.1 million, respectively, of non-marketable private equity
securities.

the Company's exposures to market risk, as well as the Company's objectives,
policies and strategies relating to the management of such risks. The relative
sensitivity to changes in fair value from interest rates and equity prices at

                           PART II  OTHER INFORMATION
 
ITEM 1.  LEGAL PROCEEDINGS
 
     In late 1995 and thereafter, a number of purported class actions were
commenced in various state and federal courts against the Company alleging that
the Company engaged in deceptive sales practices in connection with the sale of
whole and/or universal life insurance policies from the early 1980s to the mid
1990s. 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/or
violation of state insurance and/or deceptive business practice laws).
Plaintiffs in these cases (including the Goshen case discussed below) seek
primary equitable relief (e.g. reformation, specific performance, mandatory
injunctive relief prohibiting the Company from canceling policies for failure to
make required premium payments, imposition of a constructive trust and/or
creation of a claims resolution facility to adjudicate any individual issues
remaining after resolution of all class-wide issues) as opposed to compensatory
damages, although they seek compensatory damages in unspecified amounts. The
Company has answered the complaints in each action (except for one recently
filed action and another being voluntarily held in abeyance), has denied any
wrongdoing, and has 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 Company and sold on an alleged "vanishing
premium" basis during the period January 1, 1982 to December 31, 1995. On March
27, 1997, the Company filed a motion to dismiss or, alternatively, for summary
judgment on all counts of the complaint. All of the other putative class actions
(with one exception discussed below) have been 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. The Massachusetts District
Court in the Multidistrict Litigation has entered an order essentially holding
all of the federal cases in abeyance pending the action of the Goshen case.
 
     On October 21, 1997, the New York State Supreme Court granted the Company's
motion for summary judgment and dismissed all claims filed in the Goshen case
against the Company on the merits. On March 18, 1999 the order by the New York
State Supreme Court was affirmed by the New York State Appellate Division, First
Department. On April 19, 1999, plaintiffs filed a motion to the New York State
Court of Appeals for leave to appeal from the final determination of the
Appellate Division which affirmed the New York Supreme Court's order granting
summary judgment and dismissing the complaint. All actions before the United
States District Court for the District of Massachusetts are still pending. In
addition, on or about February 25, 1999, a purported class action was filed
against MONY Life Insurance Company of America in Kentucky state court covering
policyholders who purchased individual universal life insurance policies from
MLOA after January 1, 1988 claiming breach of contract and violations of the
Kentucky Consumer Protection Act. On March 26, 1999, MLOA removed that action to
the United States District Court for the Eastern District of Kentucky, requested
the Judicial Panel on multidistrict litigation to transfer the action to the
multidistrict litigation in the District of Massachusetts and sought a stay of
further proceedings in the Kentucky District Court pending a determination on
multidistrict transfer. On April 19, 1999, the Judicial Panel entered a
conditional transfer order transferring the case to the Federal District Court
in Massachusetts. Plaintiffs have submitted a motion in opposition to the
transfer. There can be no assurance that the present or any future litigation
relating to sales practices will not have a material adverse effect on the
Company.
 
     In addition to the foregoing, from time to time MONY is a party to
litigation and arbitration proceedings in the ordinary course of its business,
none of which is expected to have a material adverse effect on MONY.
