                                EEX CORPORATION
              Notes to Condensed Consolidated Financial Statements


1.  In the opinion of management, all adjustments (consisting only of normal
    recurring accruals) necessary for a fair presentation of the financial
    position, results of operations and cash flows for the interim periods
    included herein have been made. Certain items in prior periods have been
    reclassified to be consistent with the current presentation.

2.  On December 22, 1998, EEX entered into a Purchase Agreement ("Agreement")
    that provided the Company would receive $150 million and issue to the
    purchaser 1,500,000 shares of Series B 8% Cumulative Perpetual Preferred
    Stock (the "Preferred Stock") and Warrants to acquire 21 million shares of
    the Company's common stock. On January 8, 1999, the transaction was closed
    and EEX issued the Preferred Stock and Warrants in exchange for $150
    million.

   Each share of Preferred Stock has a stated value of $100 and a current
   dividend rate of 8% per year, payable quarterly. The 8% dividend rate will be
   adjusted to a market rate, not to exceed 18%, after seven years or the
   earlier occurrence of certain events including a change of control (as
   defined in the Agreement). Prior to any adjustment of the dividend rate, the
   Company may, at the Company's option, accrue dividends or pay them in cash,
   shares of Preferred Stock or shares of common stock. After any adjustment of
   the dividend rate, dividends must be paid in cash. The Preferred Stock is
   entitled to a liquidation preference of $100 per share plus accrued and
   unpaid dividends. The Preferred Stock may be redeemed, in whole but not in
   part, by the Company at any time for cash at the stated value plus accrued
   and unpaid dividends. Until any adjustment of the dividend rate, holders of
   the Preferred Stock will be entitled to cast an aggregate of eight million
   votes on matters voted upon by the common stock holders, and to a separate
   class vote on certain matters affecting the Preferred Stock. EEX has entered
   into a Registration Rights Agreement to register under the Securities Act of
   1933, and maintain the effectiveness of such registration of, the resale of
   the Preferred Shares, the Warrants and any common stock acquired by the
   purchaser pursuant to the Warrants. Under the terms of the Agreement, the
   purchaser has the right to add a member to the Company's Board of Directors
   and did so in January 1999. The purchaser may continue the representation on
   the Company's Board of Directors if certain conditions are maintained. In the
   event of a Change of Control, as defined in the Agreement, occurring prior to
   the sixth anniversary of the closing of the transaction, the Purchaser has
   the right to exchange all or part of the Preferred Stock and Warrants for
   shares of common stock at the rate of 18.6047 shares of common stock for each
   share of Preferred Stock and a proportionate number of Warrants, provided
   that the Company may, under certain circumstances, pay a portion of the
   exchange in cash. The exercise price of the Warrants and the exchange formula
   related to a Change of Control may be adjusted upon 

                                       4
<PAGE>
 
   the occurrence of certain events described in the anti-dilution provisions of
   the Warrants.

   The Warrants were issued in three series, each exercisable at any time
   beginning August 31, 1999 for $12 per share of common stock: (a) Series A
   Warrants to acquire 10.5 million shares, exercisable for ten years; (b)
   Series B Warrants to acquire 2.5 million shares, exercisable for seven years,
   and (c) Series C Warrants to acquire 8 million shares, exercisable for seven
   years. Until approved by the shareholders of the Company at the 1999 annual
   meeting, the Warrants will be exercisable only in the form of a stock
   appreciation right (entitled to receive the cash difference between the
   exercise price and the market price of the common stock on the trading day
   prior to the date of exercise). If approved by the shareholders, the Series A
   and Series B Warrants will be exercisable for cash or by utilizing shares of
   Preferred Stock at the stated value on a gross or net basis. The Series C
   Warrants will be exercisable only as a stock appreciation right unless the
   Company, prior to July 30, 2002, elects to allow the Series C Warrants to be
   exercised for cash or by utilizing shares of Preferred Stock at the stated
   value on a gross or net basis.

   On March 31, 1999, EEX paid dividends on the Preferred Stock of $2.8 million
   by issuing 27,667 additional Preferred Stock.

3. Early in 1998, EEX entered into two forward purchase facilities to repurchase
   shares of its common stock.  EEX has initiated several transactions under
   these facilities, which allow for settlement, at EEX's option, by physical
   delivery of the shares to EEX in exchange for cash or on a net basis in
   either shares of EEX common stock or in cash. For a net basis settlement, to
   the extent that the market price of EEX's common stock on a settlement date
   is higher (lower) than the forward purchase price, the net differential is
   received (paid) by EEX. As of March 31, 1999, transactions under these
   facilities covered approximately $8.8 million or 796,533 shares of EEX's
   common stock, with an average forward purchase price of $10.99 per share. If
   the agreements were settled on a net basis on the March 31, 1999 market price
   of EEX's common stock ($4.88 per share), EEX would be obligated to pay
   approximately $4.9 million in cash or deliver approximately 997,020 shares.

4. EEX is involved in a number of legal and administrative proceedings incident
   to the ordinary course of its business.  In the opinion of management, based
   on the advice of counsel and current assessment, any liability to EEX
   relative to these ordinary course proceedings will not have a material
   adverse effect on EEX's operations or financial condition.

   In addition, on August 3, 1998, EEX, several of its current and/or former
   officers and directors, Texas Utilities Company ("TUC") and TUC's Chief
   Executive Officer were named in a class action lawsuit filed in the Northern
   District of Texas that was designated as Gracy Fund L.P. v. EEX Corporation,
   et al., ("Gracy Fund"). The Gracy Fund complaint 

                                       5
<PAGE>
 
  alleged violations of the Securities Act of 1933 ("33 Act") and the Securities
  Exchange Act of 1934 ("34 Act") against various defendants.

  Additionally, on August 3, 1998, EEX, several of its current and/or former
  officers and directors, and two additional companies (ENSERCH Corporation and
  DeGolyer & MacNaughton) were named in a class action lawsuit filed in the
  Southern District of Texas that was designated as Stan C. Thorne v. EEX Corp.,
  et al ("Thorne").  The Thorne complaint alleged violations of the 34 Act and
  common law-based negligent misrepresentations and fraud claims.

  On October 5, 1998, the Thorne defendants filed a motion to transfer the
  Thorne action to the Northern District of Texas.  On November 20, 1998, the
  Thorne action was transferred to the Northern District of Texas and
  consolidated with the Gracy Fund action.

  On January 22, 1999, plaintiffs filed an amended class action complaint in the
  consolidated Gracy Fund action against EEX, several of its current and/or
  former officers and directors and another company, ENSERCH Corporation
  ("Consolidated Complaint").  The Consolidated Complaint alleges violations of
  Sections 11, 12(a)(2) and 15 of the 33 Act and violations of Sections 10(b),
  14(a) and 20(a) of the 34 Act against various defendants.  The Consolidated
  Complaint alleges the Sections 10(b), 15 and 20(a) claims on behalf of a class
  of plaintiffs who acquired EEX's stock pursuant to an October 1996
  Registration Statement and Proxy/Prospectus ("EEX Subclass").

  Plaintiffs allege that during the class period, defendants made materially
  false and misleading statements, and failed to disclose material facts,
  regarding the value and volume of EEX's proved reserves from its East Texas
  operations.  According to plaintiffs, these purported misrepresentations
  artificially inflated the price of EEX's common stock throughout the class
  period, induced the EEX Subclass to approve the merger that spun EEX off from
  ENSERCH and induced the EEX Subclass to acquire stock pursuant to the
  Registration Statement and Proxy/Prospectus issued regarding this merger.

  While the Company intends to contest this action vigorously and has filed a
  motion to dismiss the Consolidated Complaint, the Company cannot predict the
  outcome of this matter at this time.  All discovery is stayed pending the
  determination of the motion to dismiss.

  The operations and financial position of EEX continue to be affected from time
  to time in varying degrees by domestic and foreign political developments as
  well as legislation and regulations pertaining to restrictions on oil and gas
  production, imports and exports, natural gas regulation, tax increases,
  environmental regulations and cancellation of contract rights.  Both the
  likelihood of such occurrences and their overall effect on the Company vary
  greatly and are not predictable.  These uncertainties are part of a number of
  items that EEX has taken and will continue to take into account in
  periodically establishing accounting reserves.

Item 2. Management's Discussion and Analysis of Financial Condition and Results
        of Operations

Certain statements in this report, including statements of EEX's and
management's expectations, intentions, plans and beliefs, are "forward-looking
statements," within the meaning of Section 21E of the Securities Exchange Act of
1934, as amended, that are subject to certain events, risks and uncertainties
that may be outside EEX's control.  See "Forward Looking Statements -
Uncertainties and Risks."

RESULTS OF OPERATIONS

For the first quarter of 1999, EEX reported a net loss of $18 million ($0.43 per
share), versus a net loss of $19 million ($0.45 per share) for the same period
in 1998.  The first quarter 1998 loss includes losses on asset sales ($6
million) and additional depreciation expense associated with the disposition of
properties in East Texas ($5 million).

For the first quarter of 1999, total revenues were $40 million, or 39% lower
than 1998. Natural gas revenues, 49% lower than 1998, were impacted by both a
19% decrease in average prices and a 37% decrease in production primarily due to
property sales.  The average natural gas sales price per thousand cubic feet
("Mcf") was $1.97 in 1999, compared with $2.43 in 1998.  Natural gas production
for 1999 was 12 billion cubic feet ("Bcf"), compared with 19 Bcf in 1998. Oil
revenue decreased 10% from the same period in 1998 due to a drop in price from
$15.95 to $11.17 per barrel, offset by an increase in oil production primarily
from the Mudi Field in Indonesia.

Costs and expenses for the first quarter of 1999 were $52 million, compared with
$74 million in 1998.  Operating expenses (production and operating, general and
administrative and taxes other than income and payroll) were $16 million in
1999, 25% lower than 1998, as a result of asset sales and the favorable impact
from cost reduction measures.  Exploration expense increased 3% during the first
quarter of 1999.  Exploration expense in the first quarter of 1999 includes
approximately $6 million associated with a dry hole at Vermillion Block 37.
Depreciation and amortization was $20 million, $11 million lower than 1998 due
to lower production volumes and additional depreciation expense in 1998
associated with the disposition of properties in East Texas.

Total interest and other financing costs for the first quarter of 1999,
including minority interest and preferred stock dividends, were $7 million, a $2
million decrease from 1998.  Reduced debt and redemption of the outstanding
preferred securities of a subsidiary were the primary reasons for the decrease.
This decrease was partially offset by the dividends associated with the newly
issued preferred shares.

LIQUIDITY AND CAPITAL RESOURCES

Net cash flows provided by operating activities during the first quarter of 1999
were $11 million, compared to net cash flows used in operating activities of $6
million in 1998.  The increase in operating cash flow was largely due to reduced
working capital requirements in 1999.

Net cash flows used in investing activities in the first quarter of 1999 were
$28 million, a $27 million decrease from 1998.  In 1998, the Company purchased
additional interest in the Tuban Production Sharing Contract for approximately
$42 million and realized $20 million in proceeds from property sales.

On December 22, 1998, EEX entered into a Purchase Agreement which provides that
the Company would receive $150 million and issue to the purchaser 1,500,000
shares of Series B 8% Cumulative Perpetual Preferred Stock and Warrants to
acquire 21 million shares of the Company's common stock.  The transaction closed
on January 8, 1999 when EEX issued the Preferred Stock and Warrants in exchange
for $150 million.

EEX intends to utilize substantially all of its internally generated cash flows
for growth of the business and expects to fund its business plans using
available cash flow from operations, proceeds from the issuance of Preferred
Stock, asset sales, and borrowings under credit facilities.

                                       8
<PAGE>
 
EEX has a $350 million revolving credit line with a group of banks that matures
on June 27, 2002, of which none was used at March 31, 1999. The revolving credit
agreement limits, at all times, total debt, as defined, to the lesser of 60% of
capitalization, as defined, or $1 billion, and prohibits liens on property
except under certain circumstances. A portion of the funds available under the
revolving credit line may be borrowed on a short-term basis at current money
market rates.

At March 31, 1999, debt, including both capital and operating leases as defined
in loan agreements, represented 38% of total capitalization, compared to 57% at
March 31, 1998.

YEAR 2000 ISSUE

During the first quarter of 1999, EEX completed an inventory, assessment and
risk analysis of its Information Technology systems which includes the Company's
business and financial software applications, geological and geophysical
software applications, operating systems, hardware and the interfaces and
interdependencies between these systems.  A testing plan has been developed for
the Accounting and Human Resources system software.  The Accounting system
software was recently upgraded to a version certified by the vendor to be Year
2000 compliant and will be tested in accordance with the plan.

An Onshore and Offshore embedded chip inventory, assessment, and risk analysis
was also completed.  This program found 185 non-compliant and indeterminate
components that require replacement or other remediation.  Planning for
corrective actions is underway; corrective actions are expected to be
substantially completed by the end of the third quarter of 1999.

At the end of the first quarter, adequate responses had been received from 70%
of the critical and important external agents (third parties upon whom the
Company relies for goods and services in order to conduct its day to day
business). Efforts are underway to obtain responses from the remaining external 
agents.

Contingency plans for each of the three areas above will be developed beginning
in the second quarter to assess the impact to the Company where risk has not
been adequately minimized. To date, EEX has spent approximately $0.7 million of
a budgeted $1.5 million in addressing the Year 2000 issue.

The failure to correct a material Year 2000 problem could result in an
interruption in, or a failure of, certain normal business activities or
operations.  Such failures could materially and adversely affect the Company's
results of operations, liquidity and financial condition.  Due to the general
uncertainty inherent in the Year 2000 problem, resulting in part from the
uncertainty of the Year 2000 readiness of third-party suppliers and customers,
no assurances can be given that business interruptions arising from the Year
2000 issue will not occur.  However, 

                                       9
<PAGE>
 
the Company believes that implementation of its Year 2000 readiness program will
reduce the potential for material adverse consequences to occur.

FORWARD LOOKING STATEMENTS --UNCERTAINTIES AND RISKS

Certain statements in this report, including statements of EEX's and
management's expectations, intentions, plans and beliefs, are "forward-looking
statements," within the meaning of Section 21E of the Securities Exchange Act of
1934, as amended, and are subject to certain events, risks and uncertainties
that may be outside EEX's control. These forward-looking statements include
statements of management's plans and objectives for EEX's future operations and
statements of future economic performance; information regarding drilling
schedules, expected or planned production, future production levels of
international and domestic fields, EEX's capital budget and future capital
requirements, EEX's meeting its future capital needs, the level of future
expenditures for environmental costs and the outcome of regulatory and
litigation matters; and the assumptions underlying such forward-looking
statements. Actual results and developments could differ materially from those
expressed in or implied by such statements due to a number of factors,
including, without limitation, those described in the context of such forward-
looking statements and the risk factors set forth below and described from time
to time in EEX's other documents and reports filed with the Securities and
Exchange Commission.

Exploration Risk--Exploration for oil and gas in the Deepwater Gulf of Mexico
and unexplored frontier areas have inherent and historically high risk. EEX is
focusing on exploration opportunities in offshore and international areas which
will increase associated exploration risk. Future reserve increases and
production will be dependent on EEX's success in these exploration efforts and
no assurances can be given of such success. Exploration may involve unprofitable
efforts, not only with respect to dry wells, but also with respect to wells that
are productive but do not produce sufficient net revenues to return a profit
after drilling, operating and other costs.

Operational Risks and Hazards--EEX's operations are subject to the risks and
uncertainties associated with finding, acquiring and developing oil and gas
properties, and producing, transporting and selling oil and gas. Operations may
be materially curtailed, delayed or canceled as a result of numerous factors,
such as accidents, weather conditions, compliance with governmental requirements
and shortages or delays in the delivery of equipment. Operating hazards such as
fires, explosions, blow-outs, equipment failures, abnormally pressured
formations and environmental accidents may have a material adverse effect on
EEX's operations or financial condition. EEX's ability to sell its oil and gas
production is dependent on the availability and capacity of gathering systems,
pipelines and other forms of transportation.

Offshore Risks--EEX's Gulf of Mexico oil and gas reserves include properties
located in water depths of 20 to greater than 7,000 feet where operations are by
their nature more difficult than drilling operations conducted on land in
established producing areas. Deepwater drilling and operations require the
application of more advanced technologies that involve a higher risk of
mechanical failure and can result in significantly higher drilling and operating
costs. Furthermore, offshore operations require a significant amount of time
between the discovery and the time the gas or oil is actually marketed,
increasing the market risk involved with such operations.

                                       10
<PAGE>
 
Volatility of Oil and Gas Markets--EEX's operations are highly dependent upon
the prices of, and demand for, oil and gas. These prices have been, and are
likely to continue to be, volatile. Prices are subject to fluctuations in
response to a variety of factors that are beyond the control of EEX, such as
worldwide economic and political conditions as they affect actions of OPEC and
Middle East and other producing countries, and the price and availability of
alternative fuels. EEX's hedging activities with respect to some of its
projected oil and gas production, which are designed to protect against price
declines, may prevent EEX from realizing the benefits of price increases above
the levels of the hedges.

Estimating Reserves and Future Net Cash Flows--Uncertainties are inherent in
estimating quantities and values of reserves and in projecting rates of
production, net revenues and the timing of development expenditures. Reserve
data represent estimates only of the recovery of hydrocarbons from underground
accumulations and are often different from the quantities ultimately recovered.
Downward adjustment in reserve estimates could adversely affect EEX. Also, any
substantial decline in projected net revenues resulting from production of
reserves could have a material adverse effect on the Company's financial
position and results of operations.

Capital Funding--EEX's access to public or private equity or debt markets may be
limited by general conditions in or volatility of the markets or conditions
affecting the oil and gas industry. No assurances can be given that the Company
will be able to secure funds in these markets, or that such funds will be
obtained on terms favorable to the Company.

Government Regulation--EEX's business is subject to certain federal, state and
local laws and regulations relating to the drilling for and the production of
oil and gas, as well as environmental and safety matters. See "Business--
Government Regulation" and "Environmental Matters," in the Company's Annual
Report on Form 10-K. Enforcement of or changes to these regulations could have a
material impact on the Company's operations, financial condition and results of
operations.

International Operations--EEX's interests in properties in countries outside the
United States are subject to the various risks inherent in foreign operations.
These risks may include, among other things, currency restrictions and exchange
rate fluctuations, loss of revenue, property and equipment as a result of
expropriation, nationalization, war, insurrection and other political risks,
risks of increases in taxes and governmental royalties, renegotiations of
contracts with governmental entities, changes in laws and policies governing
operations of foreign-based companies and other uncertainties arising out of
foreign government sovereignty over the Company's international operations. The
Company's international operations may also be adversely affected by laws and
policies of the United States affecting foreign trade, taxation and investment.
In addition, in the event of a dispute arising from foreign operations, the
Company may be subject to the exclusive jurisdiction of foreign courts or may
not be successful in subjecting foreign persons to the jurisdiction of the
courts of the United States.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

In the first quarter of 1999, EEX realized a net gain on hedging activities,
before the effect of taxes, of $1.5 million.  The table below provides
information about EEX's hedging techniques for oil and natural gas as of March
31, 1999.  The Notional Amount is equal to the net volumetric hedge position of
EEX during the periods.  The fair values of the hedging techniques are based on
the difference between the strike price and the New York Mercantile Exchange
future prices for the applicable trading month of 1999 and 2000.

EEX has a contractual requirement to purchase gas for delivery to a Co-
generation plant in East Texas.  The below hedges were placed during the first
quarter of 1999 on those delivery volumes and are not included in the above gas
hedging table.  The Notional Amount is equal to the net volumetric position of
EEX during the period.  The fair values of the hedging techniques are based on
the difference between the strike price and the New York Mercantile Exchange
future prices for the applicable trading month of 1999 and 2000.

                           PART II  OTHER INFORMATION

Item 2.  Changes in Securities and Use of Proceeds

On January 8, 1999, pursuant to a Purchase Agreement ("Agreement") dated
December 22, 1998, the Company issued to Warburg, Pincus Equity Partners, L.P.,
Warburg, Pincus Netherlands Equity Partners I, C.V., Warburg, Pincus Netherlands
Equity Partners II, C.V., and Warburg, Pincus Netherlands Equity Partners III,
C.V. (the "Purchasers") 1.5 million shares of Series B 8% Cumulative Perpetual
Preferred Stock (the "Preferred Stock") and Warrants to acquire 21 million
shares of the Company's common stock in exchange for $150 million.  There were
no underwriting discounts or commissions.  The securities were exempt from
registration under Section 4(2) of the Securities Act of 1933.

Each share of Preferred Stock has a stated value of $100 and a current dividend
rate of 8% per year, payable quarterly.  The 8% dividend rate will be adjusted
to a market rate, not to exceed 18%, after seven years or the earlier occurrence
of certain events including a change of control (as defined in the Agreement).
Prior to any adjustment of the dividend rate, the Company may, at the Company's
option, accrue dividends or pay them in cash, shares of Preferred Stock or
shares of common stock.  After any adjustment of the dividend rate, dividends
must be paid in cash.  The Preferred Stock is entitled to a liquidation
preference of $100 per share plus accrued and unpaid dividends. The Preferred
Stock may be redeemed, in whole but not in part, by the Company at any time for
cash at the stated value plus accrued and unpaid dividends. Until any adjustment
of the dividend rate, holders of the Preferred Stock will be entitled to cast an
aggregate of eight million votes on matters voted upon by the common stock
holders, and to a separate class vote on certain matters affecting the Preferred
Stock.  EEX has entered into a Registration Rights Agreement to register under
the Securities Act of 1933, and maintain the effectiveness of such registration
of, the resale of the Preferred Shares, the Warrants and any common stock
acquired by Purchasers pursuant to the Warrants. Under the terms of the
Agreement, the Purchasers have the right to add a member to the Company's Board
of Directors and did so in January 1999.  The Purchasers may continue the
representation on the Company's Board of Directors if certain conditions are
maintained.  In the event of a Change of Control, as defined in the Agreement,
occurring prior to the sixth anniversary of the closing of the transaction, the
Purchasers have the right to exchange all or part of the Preferred Stock and
Warrants for shares of EEX common stock at the rate of 18.6047 shares of common
stock for each share of Preferred Stock and proportionate number of Warrants,
provided that the Company may, under certain circumstances, pay a portion of the
exchange in cash.  The exercise price of the Warrants and the exchange formula
related to a Change of Control may be adjusted upon the occurrence of certain
events described in the anti-dilution provisions of the Warrants.

The Warrants were issued in three series, each exercisable at any time beginning
August 31, 1999 for $12 per share of common stock: (a) Series A 

                                       13
<PAGE>
 
Warrants to acquire 10.5 million shares, exercisable for ten years; (b) Series B
Warrants to acquire 2.5 million shares, exercisable for seven years, and (c)
Series C Warrants to acquire 8 million shares, exercisable for seven years.
Until approved by the shareholders of the Company at the 1999 annual meeting,
the Warrants will be exercisable only in the form of a stock appreciation right
(entitled to receive the cash difference between the exercise price and the
market price of the common stock on the trading day prior to the date of
exercise). If approved by the shareholders, the Series A and Series B Warrants
will be exercisable for cash or by utilizing shares of Preferred Stock at the
stated value on a gross or net basis. The Series C Warrants will be exercisable
only as a stock appreciation right unless the Company, prior to July 30, 2002,
elects to allow the Series C Warrants to be exercised for cash or by utilizing
shares of Preferred Stock at the stated value on a gross or net basis.

The Purchasers have agreed to standstill provisions for ten years that restrict
their purchases of additional shares of common stock, prohibit sales by the
Purchasers of common stock or Warrants to any person or group that would
beneficially own more than 10% (5% in the case of a competitor of the Company)
of the outstanding common stock after the sale, prohibits the Purchasers from
proposing business combinations involving the Company or soliciting proxies, and
limits the Purchasers' aggregate voting rights to one vote less than 20% of the
aggregate number of votes entitled to be cast on any matter by holders of common
stock or any other class of capital stock.  If the Purchasers would otherwise be
entitled to cast votes in excess of the standstill agreement's limit, such
additional votes will be cast in the same proportion as the votes cast by all
other shareholders.

In the Agreement, the Company agreed to use the proceeds from the sale of the
Securities for the purposes of funding exploration and production appraisal and
development activities, for working capital and for general corporate purposes.
