                        PROSPECTUS/INFORMATION STATEMENT

                         NEW ENSERCH EXPLORATION, INC.
                       ENSERCH EXPLORATION PARTNERS, LTD.

                       104,581,242 Shares of Common Stock

     This Prospectus/Information Statement is being sent to holders of
Depositary Units Representing Limited Partnership Interests ("EP Depositary
Units") of Enserch Exploration Partners, Ltd. ("EP"). Enserch Exploration, Inc.,
a Delaware corporation ("EEI"), as Managing General Partner of EP, is proposing
a plan of reorganization (the "Reorganization"). EEI is a wholly owned
subsidiary of ENSERCH Corporation ("EC"). EC and its controlled corporate
subsidiaries and their controlled partnerships (including EEI, but not EP and
EPO (as defined below)) are collectively referred to herein as the "EC
Companies." Pursuant to the Reorganization a newly organized Texas corporation,
also to be named Enserch Exploration, Inc. ("Newco"), will acquire all of the
outstanding partnership interests of EP Operating Limited Partnership ("EPO"),
which is a limited partnership in which EP has a 99% limited partner interest
and which holds EP's gas and oil properties, in exchange for shares of common
stock of Newco, par value $1.00 per share ("Common Stock"). EPO will then be
merged into Newco. Thereafter EP will be liquidated, with all partners of EP
receiving shares of Common Stock, and the EC Companies also receiving EP's
interests in and assuming EP's obligations under certain equipment lease
arrangements (the equipment will be subleased to Newco) and assuming
approximately $395 million principal amount of EP's indebtedness, plus accrued
interest. Upon the liquidation of EP and the distribution of Common Stock, the
EC Companies and the other holders (the "Public Unitholders") of outstanding
limited partnership interests ("Units") will receive one share of Common Stock
for each Unit then held. Public Unitholders will receive an aggregate of 805,914
shares of Common Stock pursuant to the Reorganization and the EC Companies,
collectively, will receive 103,775,328 shares of Common Stock pursuant to the
Reorganization. The ratio of exchange to be used in the Reorganization does not
result in any change in the relative holdings of the Public Unitholders and the
EC Companies with respect to their ownership interests in EP. The ratio of
exchange was not changed as a result of the assumption of EP debt by the EC
Companies or the assignment and assumption of the equipment leases. Consummation
of the Reorganization is expected to commence on December 30, 1994. Prior to
this time there has been no public market for the Common Stock. However, the New
York Stock Exchange (the "NYSE") has indicated to Newco that the Common Stock to
be distributed to the Public Unitholders pursuant to the Reorganization will be
approved for listing on the NYSE, subject to official notice of issuance, under
the symbol "EEX."

     The Reorganization must be approved by the holders of a majority of the
outstanding Units. Since the EC Companies own an aggregate of approximately
99.2% of the outstanding Units, and intend to consent to the steps necessary to
consummate the Reorganization, the approval of the proposal is assured without
the consent of any other holder of Units.
<PAGE>
 
ACCORDINGLY, EP IS NOT SOLICITING YOUR CONSENT TO THE REORGANIZATION, AND YOU
ARE REQUESTED NOT TO SEND EP A CONSENT OR PROXY WITH RESPECT TO THE
REORGANIZATION.

     All Public Unitholders of record at the close of business on December 5,
1994 will receive this Prospectus/Information Statement.

                                _______________

     For a discussion of certain special factors that should be considered, see
"Special Considerations." In particular, Public Unitholders should consider the
following factors:

     .  EEI may be viewed as having a potential conflict of interest with the
        Public Unitholders with respect to the determination of the terms of the
        Reorganization.

     .  The terms of the Reorganization were evaluated and determined by EEI
        without independent representation of the Public Unitholders.

     .  Unlike EP, Newco will be subject to corporate tax, and its earnings and
        profits distributed to shareholders will also be subject to taxation to
        the shareholders.

     .  Public Unitholders will have no dissenters' rights in the Reorganization
        and therefore cannot elect to receive cash for their EP Depositary Units
        based on an appraisal.

     .  Immediately following the consummation of the Reorganization, the EC
        Companies will own over 99% of the outstanding Common Stock.

     .  Newco, like EP, will be subject to all of the business and operating
        risks inherent in gas and oil exploration and production activities.

                                _______________

     EP IS NOT ASKING YOU FOR A CONSENT OR PROXY AND YOU ARE REQUESTED NOT TO
     SEND EP A CONSENT OR PROXY.

                                _______________


     THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES
 AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE
 SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED
 UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS/INFORMATION STATEMENT. ANY
 REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

                                _______________

     The date of this Prospectus/Information Statement is December 9, 1994.

information appearing elsewhere in this Prospectus/Information Statement. Public
Unitholders are urged to review carefully this Prospectus/Information Statement
in its entirety. Capitalized terms used herein without definition have the
meanings ascribed to them elsewhere in this Prospectus/Information Statement.

     In this Prospectus/Information Statement, (i) Enserch Exploration Partners,
Ltd., a publicly traded Texas limited partnership, is referred to as "EP," (ii)
Enserch Exploration, Inc., a Delaware corporation and Managing General Partner
of EP, is referred to as "EEI," (iii) EP Operating Limited Partnership, a Texas
limited partnership which holds all of EP's gas and oil properties, is referred
to as "EPO," (iv) New Enserch Exploration, Inc., a newly organized Texas
corporation that will change its name to Enserch Exploration, Inc., is referred
to as "Newco," (v) ENSERCH Corporation, a Texas corporation ("EC"), and its

EP and EPO) are referred to collectively as the "EC Companies," and (vi) the
limited partnership interests in EP, including those evidenced by EP Depositary
Units, are referred to as "Units."

Introduction

     Following the Reorganization, the business now conducted by EP, a limited
partnership, will be conducted by Newco, a corporation. EP, EC and EEI will
contribute their partnership interests in EPO to Newco in exchange for shares of
Common Stock. EPO will then be merged into Newco. Soon thereafter, EP will be
liquidated, with (i) Common Stock being distributed to the Public Unitholders
and the EC Companies that are partners of EP pro rata in relation to their
interests in EP, (ii) EEI receiving EP's interests in, and assuming EP's
obligations under, certain equipment lease arrangements relating to the Garden
Banks Block 388 Project and the Mississippi Canyon Block 441 Project (together
with certain associated assets, the "Equipment Leases") and the equipment will
be subleased to Newco (see "CERTAIN TRANSACTIONS") and (iii) the EC Companies
assuming approximately $395 million in aggregate principal amount of debt of EP
($86 million of which is debt owed by EP to EPO and thus does not appear on EP's
consolidated financial statements) owed to certain EC Companies and to Newco,
plus accrued interest.

     Currently, the EC Companies own approximately 99.2% of EP. The remaining
approximate .8% limited partner interest in EP is represented by EP Depositary
Units that are traded on the NYSE, and are owned by the Public Unitholders.

     The EC Companies own the following interests in EP:

     (1)  The Managing General Partner of EP is EEI, which owns a 1% general
          partner interest in EP. EEI is a wholly-owned corporate subsidiary of
          EC.
<PAGE>
 
     (2)  Enserch Processing Partners, Ltd., a Texas limited partnership
          ("EPPL") in which EC directly or indirectly owns all of the general
          and limited partner interests, owns a 98.2% limited partner interest
          in EP.

          EP owns a 99% limited partner interest in EPO, which holds EP's
various gas and oil exploration and production assets. EEI owns a .99% general
partner interest in EPO, and EC owns a .01% general partner interest in EPO. As
part of the Reorganization, all of these interests in EPO will be contributed to
Newco in exchange for Common Stock.

Business

     EP, through EPO, is engaged in the exploration for and the development,
production and marketing of natural gas and crude oil throughout Texas, offshore
in the Gulf of Mexico, onshore in the Gulf Coast and in various other areas of
the United States. Activities include geological and geophysical studies;
acquisition of domestic gas and oil leases; drilling of exploratory wells;
development and operation of producing properties; acquisition of interests in
developed or partially developed properties; and the marketing of natural gas,
crude oil and condensate. Production offices are maintained in Dallas, Houston,
Athens, Bridgeport, Longview and Midland, Texas. The address of each of EP and
Newco is 4849 Greenville Avenue, Suite 1500, Dallas, Texas 75206-4186 and the
telephone number of each is (214) 748-1110. See "BUSINESS."

     It is expected that EC will conduct all of its domestic gas and oil
exploration and production business through Newco, and, therefore, EC intends to
make any acquisition of domestic gas and oil properties through Newco. There may
be circumstances, however, in which it is either necessary or appropriate for EC
to make an acquisition or undertake domestic operations without Newco's
participation. EP has not conducted international gas and oil operations and EC
will continue to conduct these through affiliates other than Newco. After the
Reorganization, Newco will be provided the opportunity to purchase the remainder
of EC's domestic gas and oil properties, which are presently believed by EEI to
have a fair market value of $1.4 million. The book value of these properties is
$5.3 million. Therefore, EC would receive $3.9 million less than the carrying
value of the properties. The $1.4 million proceeds would be credited to EC's
property account under full-cost accounting rules and no gain or loss would be
recognized for accounting purposes. For tax purposes, since it has no tax basis
in the properties EC would realize a gain equal to the proceeds and would pay
current income taxes of $.5 million. The Board of Directors of Newco will
consider such decision in the ordinary course of its deliberations. No EC
Company intends to conduct any domestic gas and oil exploration and production
activities following the Reorganization.

     Newco will conduct substantially the same business as was conducted by EP
prior to the reorganization. For information regarding reserves, if any, for
obligations not paid prior to liquidation of EP see "THE REORGANIZATION--THE
PLAN OF LIQUIDATION." There are not expected to be any material differences
between the business plans, cash distribution policies or management
compensation policies of Newco and EP. Pursuant to a change in EC's

                                     - 2 -
<PAGE>
 
corporate practice that was effective before the Reorganization was initiated,
certain costs incurred by EC are being allocated to Newco in the amount of
approximately $1 million annually. Prior to 1994, management fees were not
allocated to EP by EC because they were not material. See "DIVIDEND POLICY OF
NEWCO", "MANAGEMENT" and "CERTAIN TRANSACTIONS."

     Certain conflicts of interest could arise as a result of the relationships
between the EC Companies and Newco. For example, the EC Companies will purchase
and market natural gas produced from Newco's properties. These transactions
create the potential for conflicts over pricing, terms of delivery and other
matters. A number of transactions and relationships between Newco and the EC
Companies are contemplated and specifically authorized by Article Eleven of
Newco's Restated Articles of Incorporation. For example, Article Eleven
authorizes Newco to enter into contracts with any EC Company (including entities
in which EC has a direct or indirect interest) as long as the transaction is
authorized or ratified by a majority of the Board of Directors of Newco. Except
as set forth in Article Eleven, Newco does not have any policy or procedure in
effect for approving transactions between Newco and EC Companies. See
"RELATIONSHIP BETWEEN NEWCO AND THE EC COMPANIES--CONFLICTS OF INTEREST."

Special Considerations

     Public Unitholders should carefully consider the following factors in
addition to the other information included in this Prospectus/Information
Statement. These factors are summarized below and described in more detail under
"SPECIAL CONSIDERATIONS."

     The Reorganization

     Conflicts of Interest of EEI. There is a potential conflict of interest
between EEI and the Public Unitholders with respect to the determination of the
exchange ratio in the Reorganization. A benefit to each of EEI and EC which is
not shared by all Public Unitholders is the elimination of their liability as
general partners for the obligations and liabilities of Newco that occur after
the Reorganization. Additionally, Public Unitholders were not represented in
establishing the terms of the Reorganization. Such representation might have
caused the terms of the Reorganization to be different in some respects from
those described herein, including the number of shares of Common Stock, or the
percentage of Common Stock, to be allocated to the Public Unitholders in
connection with the Reorganization.

     Shareholder Rights Differ from Limited Partner Rights. As a result of the
Reorganization, Public Unitholders will lose certain rights associated with
their ownership of Units, including without limitation the right to receive
distributions, if any, free from any income tax at the partnership level, and
will acquire certain rights associated with their ownership of Common Stock,
including without limitation the right to vote in the election of directors.

                                     - 3 -
<PAGE>
 
     No Previous Market for Common Stock.  At present there is no trading market
for the Common Stock. There can be no assurance that holders of the Common Stock
will be able to sell their shares at favorable prices or that the trading price
for a share of Common Stock will be comparable to the trading price for an EP
Depositary Unit immediately before the Reorganization is consummated.

     Double Taxation.  Unlike EP, Newco's taxable income will be subject to
taxation at the corporate level, and its earnings and profits distributed to
shareholders will also be subject to taxation at the shareholder level.

     Newco

     There are several factors to be considered because Newco will be operating
in corporate form. In addition, Newco will conduct the same business as was
conducted by EP. Accordingly, the same risks inherent in the gas and oil
exploration and production business present in EP will be present in Newco.

     Control of Newco by EC.  Immediately following the consummation of the
Reorganization, the EC Companies will own over 99% of the outstanding Common
Stock. So long as EC directly or indirectly continues to own more than 50% of
the Common Stock, EC will be able to elect all of the members of the Board of
Directors of Newco, and thus be able to control Newco. In addition, certain
conflicts of interest could arise as a result of the relationship between the EC
Companies and Newco.

     Lack of Termination Date.  Newco will have an indefinite life, whereas EP
has a definite termination date of December 31, 2035. Investors in Newco may
have to sell their shares of Common Stock in order to liquidate their
investment.

     Future Dilution of Common Stock.  Newco will be permitted to issue
additional equity or debt securities, including shares of preferred stock.
Issuances of additional shares of Common Stock or shares of preferred stock
could adversely affect shareholders' equity interest in Newco and the market
price of the Common Stock, and the interests in the assets, liabilities, cash
flow and results of operations of Newco represented by the shares of Common
Stock issued pursuant to the Reorganization may be diluted. Newco intends to
increase the level of minority ownership in Newco. Such an increase would have
the effect of diluting the percentage of Newco owned by the Public Unitholders
and the EC Companies.

      Elimination of General Partner Liability.  If the Reorganization is
consummated, EEI will be a shareholder of Newco instead of a general partner,
and will not have liability for the debts and obligations of Newco that it
previously had because it was the Managing General Partner of EP.

     No Dissenters', Appraisal or Similar Rights for Public Unitholders. Public
Unitholders who object to the Reorganization will have no appraisal, dissenters'
or similar rights. Therefore,

                                     - 4 -
<PAGE>
 
Public Unitholders will not be entitled to receive cash payments from EP for the
value of their Units if they disagree with the Reorganization. Public
Unitholders who object to the Reorganization should, however, be able to sell
either their Units or shares of Common Stock, as the case may be, on the NYSE
either before or after the Reorganization. The lack of dissenters', appraisal or
similar rights in connection with the transaction will not prevent a Public
Unitholder from challenging the fairness of the Reorganization through
appropriate legal proceedings.

     Reserve Development and Production Risks.  Newco's gas and oil exploration,
development and production operations will involve numerous risks that could
result in the failure to find new reserves or fully produce existing and
discovered reserves.

     Volatility of Gas and Oil Markets.  The operating results of Newco will be
dependent to a substantial degree on prices for natural gas and oil, both of
which are affected by many factors beyond the control of producers and have
demonstrated a high degree of volatility.

     Developments of Additional Reserves. Newco's future success will depend on
its ability to find or acquire additional reserves that are economically
recoverable. There can be no assurance that Newco's acquisition, development and
exploration activities will result in significant additional reserves or that
Newco will continue to be able to drill productive wells at acceptable costs.

     Uncertainties in Estimating Reserves and Future Net Cash Flows. There are
numerous uncertainties inherent in estimating quantities and values of proved
gas and oil reserves and in projecting future rates of production and the timing
of development expenditures. The historical and pro forma reserve data included
in this Prospectus/Information Statement represent estimates only and should not
be construed as being exact. Any downward adjustment to Newco's reserve
estimates could adversely affect its future prospects and the market value of
its securities.

The Reorganization

     Reorganization Steps.  EP, EC and EEI will contribute their partnership
interests in EPO to Newco in exchange for shares of Common Stock. EPO will then
be merged into Newco. Soon thereafter, EP will be liquidated, with (i) Common
Stock being distributed to the Public Unitholders and the EC Companies that are
partners of EP pro rata in relation to their interests in EP, (ii) EEI receiving
EP's interests in, and assuming EP's obligations under, the Equipment Leases and
the equipment will be subleased to Newco (see "CERTAIN TRANSACTIONS") and (iii)
the EC Companies assuming approximately $395 million in aggregate principal
amount of debt of EP ($86 million of which is debt owed by EP to EPO and thus
does not appear on EP's consolidated financial statements) owed to certain EC
Companies and to Newco, plus accrued interest. The Second Amended and Restated
Agreement of Limited Partnership of EP dated as of April 30, 1985, as amended by
Amendment No. 1 thereto dated as of September 1, 1992 and Amendment No. 2
thereto dated as of August 30, 1994 (the "EP Partnership Agreement"), will be
amended to the extent required to provide for these actions. See "THE
REORGANIZATION

                                     - 5 -
<PAGE>
 
- -- BACKGROUND" for a discussion of the Reorganization, its background and
reasons for its structure.

     As a result of the Reorganization, both EP and EPO will cease to exist. The
Public Unitholders will own approximately .8% of the outstanding Common Stock,
and the EC Companies will own approximately 99.2% of the outstanding Common
Stock. See "CAPITALIZATION."

     No Public Unitholder Consent Required. The consent of holders of a majority
of the Units is necessary to approve the Reorganization. The EC Companies own
approximately 99.2% of the outstanding Units. Therefore, since the EC Companies
intend to consent to the Reorganization, approval of the Reorganization will be
effected without the consent of any of the Public Unitholders being required or
solicited.

     Each Public Unitholder who notifies EEI of a proper purpose related to such
Public Unitholder's interest in EP is entitled to receive a list of the names
and amounts in interest of all limited partners of EP as of the date specified
in the request. The list will be furnished at the expense of the person
requesting it. The partners in EPO are EP, its limited partner, with a 99%
interest, EEI, its Managing General Partner, with a 0.99% interest, and EC, its
Special General Partner, with a 0.01% interest.

     Calculation of Exchange Ratio. The Board of Directors of EEI proposed the
ratio of exchange to be used in the Reorganization because it does not result in
any change in the proportionate holdings of the Public Unitholders and the EC
Companies with respect to their ownership interests in the underlying business
as EP is converted into Newco. Such ratio and the number of shares of Common
Stock to be issued in the Reorganization were calculated as follows: (i)
1,045,812 shares were attributed to EEI and EC in recognition of their 1%
general partner interest in EPO, (ii) 1,035,354 shares were attributed to EEI in
recognition of its 1% general partner interest in EP and (iii) 102,500,076
shares were attributed to the limited partner interests in EP. The Public
Unitholders, in recognition of their 805,914 Units (.786% of the Units), were
allocated 805,914 shares (.771%) of the Common Stock to be issued in the
Reorganization. The .015% difference in the Public Unitholders' ownership of
Units and Common Stock is due to the shares of Common Stock attributable to the
general partner interests in EPO and EP.

     In determining the exchange ratio, EEI considered other factors, including
the assumption by the EC Companies of approximately $395 million principal
amount of outstanding indebtedness of EP ($86 million of which is debt owed by
EP to EPO and thus does not appear on EP's consolidated financial statements)
owed to certain EC Companies and to Newco, plus accrued interest, the tax
consequences of the Reorganization to the EC Companies and the Public
Unitholders and the assignment and assumption of the Equipment Leases, but did
not alter the exchange ratio as a result of those factors. See "THE
REORGANIZATION--BACKGROUND."

                                     - 6 -
<PAGE>
 
     Reasons to Convert EP into Corporate Form. The Reorganization will convert
EP into corporate form, replacing partnership interests presently held by Public
Unitholders and limited and general partner interests held by EC Companies with
stock of Newco, a corporation. EEI, as Managing General Partner of EP, believes
there are several advantages of converting into corporate form at this time:

     Absence of Distributions.  EP's recent results and current business plan
required it to conserve cash resources by discontinuing distributions to holders
of Units after January 1994. EP's capital expenditures have consistently
exceeded its cash flow, which has been depressed because gas and oil prices
continue to be below the levels that existed at the time EP was organized.
Historically, funds for cash distributions were provided from investment in
additional Units by EC or from borrowings. The dilution created by the
investment and the level of borrowings required to support the cash
distributions increased to a point that the Board of Directors of EEI, the
Managing General Partner, determined that cash distributions should be
eliminated in order to continue EP as a nonliquidating entity. See "THE
REORGANIZATION--BACKGROUND." The EP Partnership Agreement presently provides
that EEI, as Managing General Partner, will review EP's accounts quarterly to
determine whether distributions are appropriate. EEI, as Managing General
Partner, has full discretion whether or not to make current distributions and as
to the source of funds for such distributions. The ability to distribute cash
free of a second level of income tax, combined with the expectation that EP
could sustain a policy of making large cash distributions, were the principal
reasons EP adopted the partnership form in 1985. Thus, as a result of the
discontinuation of distributions, the principal advantage of operating in
partnership form is not being realized by EP or holders of Units, and is not
likely to be realized in the foreseeable future. See "DIVIDEND POLICY OF NEWCO."
EEI believes that there are no significant advantages of operating as a
partnership that warrant continuing EP's operations in that form.

     Tax Consequences and Tax Reporting.  If EP retained its partnership
structure, holders of Units would be required to pay income taxes on income of
EP despite the fact that no substantial cash distributions are expected to be
made by EP in the foreseeable future, and, under current law, holders of Units
may be unable to use operating losses of EP to offset either income from other
sources or investment income of EP, because of basis, at risk or passive loss
limitations, although such operating losses could be used to offset EP
partnership income. Because a corporation is a distinct taxable entity apart
from its shareholders, Newco's operating losses cannot be used to offset the
shareholders' income, including dividend income, if any, received from Newco. In
addition, EEI believes that the complexities of tax reporting associated with
partnership investments are regarded as unduly burdensome for most Public
Unitholders under current conditions. The ownership of stock rather than
partnership units will greatly simplify tax reporting with respect to an
investment in EP on each Public Unitholder's individual federal and state income
tax returns for future years. Newco, however, will be subject to income taxes on
its taxable income at the corporate level.

     Expansion of Potential Investor Base and Greater Access to Equity Markets.
EEI anticipates that the Reorganization will expand EP's potential investor base
to include

                                     - 7 -

institutional and other investors who do not typically invest in limited
partnership securities because of various tax and administrative reasons.
Furthermore, EP expects that Newco will have greater access to the public and
private equity capital markets than EP, potentially enabling it to raise capital
on more favorable terms than are now available to EP. This greater access may be
of particular benefit if Newco proposes to issue equity securities to seek
additional funds for capital expenditures or to expand its business. Although
the issuance of additional equity by Newco would have the effect of diluting the
equity interest of the former Public Unitholders in EP, it could also result in
the Common Stock receiving additional investor interest through increased review
by research analysts. Newco intends to increase the level of minority ownership
in Newco, with the view of enabling the public market to value directly and more
effectively its gas and oil assets. However, it currently has no definitive
plans to issue additional equity securities.

     Acquisition Currency. EEI believes that current industry conditions may
provide opportunities for EP to grow through the acquisition of businesses and
assets which are complementary to its existing business at attractive prices. In
certain cases, EP may want to be able to issue equity interests as payment of
the purchase price for such acquisitions. EEI believes that an equity interest
in a corporation will be a more attractive acquisition currency than an interest
in a partnership. The issuance of additional equity by Newco would have the
effect of diluting the equity interest of the former Public Unitholders in EP.

     Reduced Legal Costs and Uncertainty. While there is an extensive body of
legal guidance with respect to corporations and their governance, there is no
comparable body of legal guidance for publicly traded limited partnerships. The
Reorganization should reduce legal costs inherent in maintaining EP as a
publicly traded limited partnership and provide greater certainty to management
with respect to a number of legal issues that are generally more settled with
respect to corporations than publicly traded limited partnerships, although EC
would owe fiduciary duties to Newco and its minority shareholders .

     Fairness Opinion.  EEI, in its capacity as Managing General Partner of EP,
has retained Dean Witter Reynolds Inc. ("Dean Witter") to render an opinion to
its Board of Directors as to the fairness of the Reorganization, taken as a
whole, to the Public Unitholders from a financial point of view. Management of
EEI met with counsel and representatives of Dean Witter on several occasions
commencing on August 24, 1994 to review generally the issues involved in
determining the fairness of the Reorganization from a financial point of view.

     Dean Witter has delivered its written opinion, dated November 15, 1994, to
the Board of Directors of EEI, to the effect that, as of the date of its
opinion, the Reorganization, taken as a whole, is fair to the Public Unitholders
from a financial point of view.

     A copy of Dean Witter's opinion, which sets forth the assumptions made,
matters considered and procedures followed by Dean Witter in rendering its
opinion, is attached to this Prospectus/Information Statement as Exhibit A and

Comparison of EP Depositary Units and Common Stock

     After consummation of the Reorganization, the business of Newco will be the
same business conducted by EP. However, the rights and limitations to which
holders of Common Stock will be subject will be similar in some respects and
will differ in other respects from those to which they are subject as holders of
Units. These rights and limitations include, but are not limited to, the
following:

                                                are comparable to
                                                those of EP.

Summary of Material Federal Income Tax Consequences

     Public Unitholders will not recognize any taxable gain or loss in
connection with the Reorganization, unless immediately prior to each
contribution by EP to Newco of limited partnership interests in EPO (i) EP's tax
basis in its limited partnership interest is less than EP's share of EPO's
liabilities transferred to Newco or Newsub (as defined herein) or (ii) a Public

                                    - 10 -
<PAGE>
 
Unitholder's tax basis in his Units is less than his share of EPO's liabilities.
In the opinion of Jackson & Walker, L.L.P., special tax counsel to EP, based on
representations of EEI, the Managing General Partner of EP and EPO, neither of
the exceptions set forth in (i) and (ii) above exists; hence Public Unitholders
will not recognize taxable gain or loss in connection with the Reorganization.
This section summarizes such counsel's opinion that is more fully discussed
under "FEDERAL INCOME TAX CONSIDERATIONS."

     After the Reorganization, Newco will be subject to tax on any net taxable
income subsequently derived. Shareholders of Newco will realize taxable income
from the ownership of stock in Newco to the extent that Newco pays dividends to
shareholders that are made out of Newco's current or accumulated earnings and
profits. In addition, shareholders of Newco will realize taxable gain to the
extent Newco does not have current or accumulated earnings and profits and makes
distributions that are in excess of a shareholder's basis in his stock.

     After EP's distribution of Common Stock to the Public Unitholders, each
Public Unitholder will have a tax basis in the Common Stock received in the
distribution equal to the Public Unitholder's tax basis in his Units immediately
before the liquidation, as adjusted (i) for 1994 operations, (ii) for any gain
recognized on the Reorganization, and (iii) by excluding any share of EP debts
that a Public Unitholder had previously included in his basis in his Units. This
basis will be prorated among all shares of Common Stock received by the Public
Unitholder. To the extent any Common Stock distributed to a Public Unitholder
ends up with a tax basis lower than its fair market value, gain will be
recognized upon the subsequent sale or other taxable disposition of that Common
Stock. Correspondingly, to the extent any Common Stock distributed to a Public
Unitholder ends up with a tax basis greater than its fair market value, loss
will be recognized upon the subsequent sale or other taxable disposition of that
Common Stock. Common Stock held by a Public Unitholder will have both a short
term and a long term holding period even though the Public Unitholder may have
owned his Units for more than one year. See "FEDERAL INCOME TAX CONSIDERATIONS--
HOLDING PERIOD."

     The passive loss limitations generally provide that individuals, estates,
trusts, certain closely held corporations and personal service corporations can
only deduct losses from passive activities (activities in which the taxpayer
does not materially participate) that are not in excess of the taxpayer's income
from such passive activities or investments. A shareholder can utilize suspended
passive losses upon the sale of all of his Common Stock to an unrelated person
in a transaction in which all gain or loss is recognized. Recently issued
regulations also indicate that some portion of a shareholder's passive losses
can be utilized to offset gain on the sale of Common Stock if the shareholder
sells substantially all of his stock to an unrelated party. Jackson & Walker,
L.L.P., special counsel to EP, is of the opinion that such losses cannot be used
to offset dividend income from Newco. The treatment of suspended passive losses
now appears to be consistent with the treatment of suspended passive losses and
sales of Units before the Reorganization.

     For an expanded discussion of tax considerations, Public Unitholders should
carefully review the information contained in "FEDERAL INCOME TAX
CONSIDERATIONS" and "THE REORGANIZATION -- BACKGROUND." PUBLIC UNITHOLDERS ARE
URGED TO CONSULT WITH THEIR OWN TAX ADVISORS WITH RESPECT TO THE SPECIFIC TAX
CONSEQUENCES TO THEM, INCLUDING THE APPLICATION AND EFFECT OF FOREIGN, STATE OR
LOCAL INCOME TAX AND OTHER LAWS.


                            SPECIAL CONSIDERATIONS

     Each Public Unitholder should carefully examine this Prospectus/Information
Statement and the Exhibits hereto. Public Unitholders should give particular
consideration to the facts set forth below.

The Reorganization

     Potential Conflicts of Interest. EEI is proposing the Reorganization
because it believes that it is in the best interests of both the Public
Unitholders and the EC Companies. EEI may, however, be viewed as having a
potential conflict of interest with the Public Unitholders with respect to the
determination of the terms of the Reorganization. The EC Companies, as holders
of over 99% of the outstanding Units, together with EEI, acting as Managing
General Partner, have the ability acting unilaterally to determine the terms of
the Reorganization. In addition, the EC Companies expect to receive benefits
from the Reorganization that will not be available to all holders of Units
generally involving (i) the elimination of their general partner liability for
obligations and liabilities of EP and EPO under partnership law and (ii) the
reduction of the EC Companies' deferred income tax liabilities by approximately
$55 million. See "THE REORGANIZATION -- BACKGROUND." If certain of these
potential conflicts of interest did not exist, it is possible that the terms of
the Reorganization might be different than the terms approved by the Board of
Directors of EEI. For additional information concerning the potential conflicts
of interest between EEI and the Public Unitholders in the Reorganization, see
"RELATIONSHIP BETWEEN NEWCO AND THE EC COMPANIES."

     No Independent Representation.  The terms of the Reorganization were
evaluated and determined by EEI without independent representation of the Public
Unitholders. Such separate representation might have caused the terms of the
Reorganization to be different in some respect from those described herein,
including the number of shares of Common Stock, or the percentage of Common
Stock, to be allocated to the Public Unitholders in connection with the
Reorganization.

     Shareholder Rights Differ from Limited Partner Rights. As a result of the
Reorganization, Public Unitholders will lose certain rights associated with
their ownership of Units, including without limitation the right to receive
distributions, if any, free from income tax at the partnership level, and will
acquire certain rights associated with their ownership of Common Stock,
including without limitation the right to vote in the election of directors. A
further

                                    - 12 -
<PAGE>
 
comparison of these factors, which may relate to investment objectives of Public
Unitholders, is set forth in "DESCRIPTION OF THE CAPITAL STOCK--COMPARISON OF
UNITS AND COMMON STOCK."

     No Previous Market for Common Stock. At present there is no trading market
for the Common Stock. However, the NYSE has indicated to Newco that the Common
Stock to be distributed to the Public Unitholders pursuant to the Reorganization
will be approved for listing on the NYSE, subject to official notice of
issuance. There can be no assurance that holders of Common Stock will be able to
sell their shares at favorable prices or that the trading price for a share of
Common Stock will be comparable to the trading price for an EP Depositary Unit
immediately before the Reorganization is consummated.

     Double Taxation.  The principal tax disadvantage of converting EP into
corporate form is that a corporation pays taxes on its taxable income, and its
shareholders generally pay taxes on any dividends from the corporation out of
current or accumulated earnings and profits. In contrast, a partnership pays no
tax and its partners pay tax on their distributive share of the partnership's
taxable income, gain, loss, deductions and credits. Because there is no current
plan to make distributions to Newco's shareholders, this distinction is not
expected to have any immediate or near term economic effect, but could have
economic effects on Newco and its shareholders (i) at such time as Newco makes a
distribution to shareholders out of Newco's current or accumulated earnings and
profits, or (ii) if Newco disposes of its assets in a taxable transaction,
whether by sale or otherwise, at a time when the value of its assets exceeds its
basis in such assets and thereafter distributes the proceeds to its
shareholders. As a result of a conversion of EP into corporate form, holders of
Units will forego the potential future tax benefits associated with operating in
partnership form, including the receipt of cash distributions free of corporate
income tax. Furthermore, holders of Units will not be able to use their
suspended passive losses to offset dividend income received from Newco, whereas
such losses could be used to offset their distributive share of operating income
from EP.

Newco

     There are several factors to be considered because Newco will be operating
in corporate form. In addition, Newco will conduct the same business as was
conducted by EP. Accordingly, the same risks inherent in the gas and oil
exploration and production business present in EP will be present in Newco.

     Control of Newco by EC. Immediately following the consummation of the
Reorganization, the EC Companies will own over 99% of the outstanding Common
Stock. So long as EC directly or indirectly continues to own more than 50% of
the Common Stock, EC will be able to elect all of the members of the Board of
Directors of Newco, and thus be able to control Newco. Certain of Newco's
directors and officers are also directors and/or officers of EC or its other
subsidiaries. Newco and the EC Companies expect to engage in future
transactions, the terms of which will be determined through negotiations between
Newco and the EC Companies. The officers and employees of EEI will become the
officers and employees

                                    - 13 -
<PAGE>
 
of Newco and will be compensated by Newco (except for certain officers that
are compensated by EC).  Previously the costs of these officers and
employees were charged to EP by EEI and thus there will be no change in the
cost of these officers and employees charged to Newco as a result of the
Reorganization.  The management cost allocation payable by Newco to EC of
approximately $1 million annually, which became effective July 1, 1994, is
not related to the Reorganization and will not be altered as a result of
EEI officers and employees becoming officers and employees of Newco because
such cost allocation relates to costs incurred solely by EC with respect to
EC personnel, not EEI personnel.  Certain officers of EC will also serve as
officers of Newco but they will receive no direct compensation from Newco.
See "CERTAIN TRANSACTIONS."

     EC intends to conduct all of its domestic gas and oil exploration and
production business through Newco, and, therefore, EC intends to make any
acquisition of domestic gas and oil properties through Newco. There may be
circumstances, however, in which it is either necessary or appropriate for EC to
make an acquisition or undertake domestic operations without Newco's
participation.

     Certain conflicts of interest could arise as a result of the relationships
between the EC Companies and Newco. For example, the EC Companies will purchase
and market natural gas produced from Newco's properties. These transactions
create the potential for conflicts over pricing, terms of delivery and other
matters. A number of transactions and relationships between Newco and the EC
Companies are contemplated and specifically authorized by Article Eleven of
Newco's Restated Articles of Incorporation. For example, Article Eleven
authorizes Newco to enter into contracts with any EC Company (including entities
in which EC has a direct or indirect interest) as long as the transaction is
authorized or ratified by a majority of the Board of Directors of Newco. In
determining whether this majority vote has been achieved, the vote of a director
of EC who is also a director of Newco may be counted toward the authorization or
ratification. In addition, under Article Eleven an EC Company may engage in
direct competition with Newco without first being obligated to offer the
transaction or other opportunity to Newco. Except as set forth in Article
Eleven, Newco does not have any policy or procedure in effect for approving
transactions between Newco and EC Companies. See "RELATIONSHIP BETWEEN NEWCO AND
THE EC COMPANIES--CONFLICTS OF INTEREST."

     Lack of Termination Date. Newco will have an indefinite life, whereas EP
has a definite termination date of December 31, 2035. Consequently, were EP to
remain in partnership form, it would be required to dissolve by December 31,
2035 (unless extended by an amendment to the EP Partnership Agreement), whereas
if EP converts into corporate form, Newco could continue in existence
indefinitely. Therefore, investors in Newco may have to sell their shares of
Common Stock in order to liquidate their investment.

     Future Dilution of Common Stock.  Newco will be permitted to issue
additional equity or debt securities, including shares of preferred stock. Under
the current rules of the NYSE, Newco may not issue shares of Common Stock equal
to 20% or more of the then outstanding

                                    - 14 -
<PAGE>
 
shares in connection with any single future transaction without shareholder
approval. Issuances of additional shares of Common Stock or shares of preferred
stock could adversely affect shareholders' equity interest in Newco and the
market price of the Common Stock, and the interests in the assets, liabilities,
cash flow and results of operations of Newco represented by the shares of Common
Stock issued pursuant to the Reorganization may be diluted. Issuances of
additional shares may be more likely after the Reorganization because EEI, as
the Managing General Partner of EP, believes that one of the advantages of the
Reorganization is that the corporate form will expand the potential investor
base, provide greater access to equity markets and permit the use of capital
stock as acquisition currency. Newco intends to increase the level of minority
ownership in Newco. Such an increase would have the effect of diluting the
percentage of Newco owned by both the Public Unitholders and the EC Companies.

     Elimination of General Partner Liability.  EEI, as the Managing General
Partner of each of EP and EPO, and EC, as a general partner of EPO, will each
receive a benefit from the Reorganization that is not shared by all holders of
Units generally in the elimination of their liability for obligations and
liabilities of EP and EPO that may occur after the Reorganization. Under Texas
law, as a general partner of a partnership, each of EEI and EC is liable to the
extent of its assets for the debts and obligations of EP (in the case of EEI)
and EPO. If the Reorganization is consummated, EEI and EC would be shareholders
of Newco and would not have liability for the debts and obligations of Newco.

     No Dissenters', Appraisal or Similar Rights for Public Unitholders. Under
the EP Partnership Agreement, the action by the holders of a majority of the
outstanding Units as of the record date, December 5, 1994, to approve the
Reorganization will bind all holders of Units. Under Texas law and the terms of
the EP Partnership Agreement, holders of Units will have no dissenters',
appraisal or similar rights in connection with the Reorganization, nor will such
rights be voluntarily accorded to holders of Units by EP or Newco. Therefore,
holders of Units will have no opportunity to dissent and demand to receive cash
payment from EP for the fair value of their Units after the Reorganization is
approved and consummated. The Units held by the Public Unitholders are listed on
the NYSE. The Common Stock to be distributed to the Public Unitholders pursuant
to the Reorganization will be listed on the NYSE. Thus, any Public Unitholders
who object to the Reorganization should be able to sell their Units or shares of
Common Stock, as the case may be, on the NYSE either before or after the
Reorganization. The lack of dissenters', appraisal or similar rights in
connection with the transaction will not prevent a Public Unitholder from
challenging the fairness of the Reorganization through appropriate legal
proceedings.

     Differing Fiduciary Duties.  The fiduciary duties owed by the directors of
Newco after the Reorganization may be less than the fiduciary duties owed by the
general partners of EP prior to the Reorganization. EEI's fiduciary duties to
the Public Unitholders include duties of loyalty and care. The general duties
owed by directors of Newco to its shareholders are similar to those applicable
to EEI in respect of EP's limited partners. At least one Texas court has stated
that the fiduciary duties of a general partner to limited partners are
comparable to those of a director to shareholders. Other courts, however, have
indicated that the fiduciary duties

                                    - 15 -
<PAGE>
 
of a general partner are greater than those of a director to shareholders.
Therefore, although it is unclear whether or to what extent there are any
differences in such fiduciary duties, it is possible that the fiduciary duties
of directors of Newco to its shareholders could be less than those of EEI to the
Public Unitholders. The remedy of shareholders for a breach of fiduciary duty of
directors is to request that the corporation bring suit against the directors
or, if the corporation fails to act, to initiate a shareholder derivative
lawsuit against the directors in the name of the corporation.

     Reserve Development and Production Risks.  Newco's gas and oil exploration,
development and production operations will involve numerous risks that could
result in the failure to find new reserves or fully produce discovered and
existing reserves. Gas and oil exploration, development and production
operations involve numerous risks, including depositional or trapping
uncertainties, encountering unusual or unexpected formations and pressures or
other conditions that may result in dry holes, failure to produce gas or oil in
commercial quantities or inability to fully produce discovered reserves. Gas and
oil drilling may involve unprofitable efforts, not only from dry wells, but from
wells that are productive but do not produce sufficient net revenues to return a
profit after drilling, operating and other costs. Completion of a well does not
assure a profit on the investment or recovery of drilling, completion and
operating costs. In addition, drilling hazards or environmental damage could
greatly increase the cost of operations, and various field operating conditions
may adversely affect Newco's production from successful wells. While close well
supervision and effective maintenance operations can contribute to maximizing
production rates over time, production delays and declines from normal field
operating conditions cannot be eliminated and can be expected to adversely
affect revenue and cash flow levels to varying degrees. Furthermore, various
wells can be expected to require recompletions or workovers at some point in
their productive lives. While the gradual depletion of producing reserves and
the need for recompletion of wells that have multiple reservoirs with limited
volume or workover of wells that develop mechanical problems is neither unusual
nor unexpected in the gas and oil industry, the timing and extent of production
declines and recompletion requirements for wells in which Newco will own
interests after the Reorganization cannot be predicted with any certainty.

     Volatility of Gas and Oil Markets. The revenues generated by Newco's
operations are highly dependent upon the prices of, and demand for, gas and oil.
For the last several years, prices of these products have reflected a worldwide
surplus of supply over demand for oil. The price received by Newco for its
natural gas and crude oil will depend upon numerous factors beyond Newco's
control, including economic conditions in the United States and elsewhere and
the world political situation as it affects OPEC, the Middle East (including the
current embargo of Iraqi crude oil from worldwide markets) and other producing
countries, the actions of OPEC and governmental regulation. The fluctuation in
world oil prices continues to reflect market uncertainty regarding OPEC's
ability to control member country production and underlying concern about the
balance of world demand for and supply of gas and oil.

     Since 1985, when EP received an average sales price of $2.94 per Mcf for
natural gas, a nationwide deliverability surplus of natural gas has prompted a
decrease in sales under higher

                                    - 16 -
<PAGE>
 
priced, long term contracts with traditional pipeline customers.  Lower priced
gas sold in the spot market has been made readily available to end-users because
of gas-to-gas competition, lower oil prices and improved transportation
opportunities. Gas sales prices were higher in 1993 and through September 30,
1994; however, recent prices are lower due to unseasonably warm weather and
above average storage levels.

     Decreases in the prices of gas and oil have had, and could have in the
future, an adverse effect on development and exploration programs, proved
reserves, revenues, profitability, cash flow and dividend levels.

     Development of Additional Reserves. Newco's future success will depend not
only on developing existing gas and oil reserves but also on its ability to find
or acquire additional reserves that are economically recoverable. The rate of
production from gas and oil properties generally declines as reserves are
depleted. Without successful exploration and development activities or reserve
acquisitions, the proved reserves of Newco will decline as gas and oil is
produced from its proved developed reserves. There can be no assurance that
Newco's acquisition, development and exploration activities will result in
significant additional reserves or that Newco will continue to be able to drill
productive wells at acceptable costs. If prevailing gas and oil prices were to
increase significantly, Newco's costs to add reserves could also be expected to
increase.

     Uncertainties in Estimating Reserves and Future Net Cash Flows.  There are
numerous uncertainties inherent in estimating quantities and values of proved
gas and oil reserves and in projecting future rates of production and the timing
of development expenditures, including factors involving reservoir engineering,
pricing and both operating and regulatory constraints. The reserve data included
in this Prospectus/Information Statement represent estimates only and should not
be construed as being exact. Reserve assessment is a subjective process of
estimating the recovery from underground accumulations of natural gas and other
hydrocarbons that cannot be measured in an exact way. Accordingly, reserve
estimates are often different from the quantities of natural gas and other
hydrocarbons ultimately recovered. Any downward adjustment could adversely
affect Newco's future prospects and the market value of its securities.

     Competition.  The gas and oil industry is highly competitive. Newco will
compete with major and other independent gas and oil companies for the
acquisition of additional properties as well as the equipment and labor required
to develop and operate its properties. Many of these competitors have
substantially greater financial and other resources than Newco.

     Governmental Regulation. The gas and oil business is subject to broad
federal and state regulations which, among other things, control the rate of gas
and oil production and establish the maximum price at which gas is sold. Newco
will also be required to comply with federal and state laws and regulations
relating to environmental matters. There can be no assurance that present and
future regulation of the gas and oil industry will not adversely affect the
operations of Newco.

                                    - 17 -
<PAGE>
 
     Hedging.  Newco may hedge some of its projected gas and oil production from
time to time through a variety of financial arrangements designed to protect
against price declines, including swaps, collar agreements and futures
agreements. To the extent Newco engages in such activities, it may be prevented
from benefiting from price increases above the levels of the hedges.

     Transaction Costs.  Transaction costs of approximately $1,000,000 will be
paid by EP, including the fee and expenses of Dean Witter, whether or not the
Reorganization is completed.

                              THE REORGANIZATION

Background

     EP was formed in 1985 to succeed to substantially all of the domestic gas
and oil exploration and production business of EC. In April 1985, EC contributed
to EP substantially all of its domestic developed and undeveloped gas and oil
properties and EP assumed certain liabilities in connection with such
contribution, including approximately $230 million of long-term debt. In
exchange, EP issued Units to EC. At the same time, EP sold 11,250,000 Units to
the public at a price of $21.50 per Unit. After this offering EC held
approximately 85% of the Units and 15% of the Units were held by Public
Unitholders. Proceeds of the offering were used by EP to repay debt assumed from
EC.

     In offering Units to the public in April 1985, EP stated its intent to
distribute $.60 per Unit on a quarterly basis through 1986 and indicated its
belief that the annual distribution rates per Unit for 1987 through 1989 would
be at least equal to the anticipated annual distribution rate for 1986, but that
there could be no assurance that future conditions would permit distributions at
such levels during such years or thereafter. EC stated that it intended, but
that it was not obligated, to invest, directly or indirectly, amounts in EP to
the extent necessary to provide funds through 1989 both to support cash
distributions to Public Unitholders and to support EP's exploration and
development expenditures at anticipated levels. EC anticipated that such funds
would be provided through loans and purchases of additional Units. EP also
stated that if its exploration and development capital expenditure budgets and
anticipated revenues over such periods remained at projected levels, it was
probable that without substantial investment by EC, EP would be unable to fund
both its anticipated cash distributions and all of its planned capital
expenditures, although EP believed that it could make up a significant portion
of any shortfall with sales of additional Units to others, borrowing or other
financings.

     During the latter half of 1985 and continuing into 1986, gas and oil prices
declined severely. This was reflected in a similar decline in EP's revenues and
net cash flows from operations. As a result, capital expenditures and
distributions to holders of Units exceeded aggregate net cash flows from EP's
operations. The cash shortfall was funded principally by additional EC
investment through purchasing Units and making loans and advances.

     In July 1986, due to the reduction in revenues and cash flow, EP announced
a reduction in quarterly distributions from $.60 per Unit to $.30 per Unit,
beginning in the first quarter of 1987. This reduction in distributions preceded
the changes in federal tax law that adversely affected the tax treatment of
publicly traded limited partnerships.

     From April 30, 1985 through October 2, 1987, EC supported EP's cash
distributions and exploration and development expenditures through the purchase
of additional Units. In accordance with the terms of the EP Partnership
Agreement, the price of Units purchased by EC was the average of the last
reported sales prices per Unit, regular way, for the five trading days

                                    - 19 -

immediately preceding the date of determination.  The following table summarizes
the purchases of Units from EP by EC.

/1/ These Units were subsequently distributed to EC shareholders.

     In October 1989, EC exchanged one-half share of EC common stock (market
value $10.00) plus $1.00 in cash for each of the 12,112,362 Units. An additional
$3.42 per Unit, plus interest, was paid in 1994 as the result of litigation
relating to the exchange.

     In January 1988, EC announced that it would not continue to invest
distributions on the Units it owned by purchasing additional Units at then
prevailing market rates but instead would lend funds to EP in amounts necessary
to support distributions and capital expenditures and indicated that future
investment would be influenced by the market price of Units and other factors.
Although the precise effects could not be predicted, the change in debt
financing was not expected to have a material effect on the market price for
Units. In the short run, any effect was expected to be somewhat favorable since
on the basis of then prevailing interest rates and Unit prices the reduction in
earnings per Unit resulting from debt financing was expected to be somewhat less
than would result from the dilution caused by the issuance of additional Units
to EC.

                                    - 20 -

     In February 1988, EP made an in-place sale of approximately 133 billion
cubic feet ("Bcf") of natural gas reserves to Encogen One Partners, Ltd.
("Encogen"), a partnership formed to own and operate a cogeneration plant in
Sweetwater, Texas. An EC Company holds a 1% general partner interest in Encogen.
EP received $158 million ($156 million net of the general partners' interests),
which was used to repay EP's and EPO's then outstanding debts to EC of $115
million incurred to finance previous capital expenditures and to fund
distributions to Public Unitholders.
 
     In February 1989, EP publicly announced that quarterly distributions on
Units would be reduced to $.075 per Unit and that EC would make an exchange
offer for Units at .5 share of EC common stock per Unit. EC also stated that if
more than half of the publicly held Units were tendered in response to its
exchange offer, the tendering would be treated as a vote favoring liquidation of
EP and that EC would liquidate EP if the Public Unitholders so voted. During the
succeeding months the exchange offer was modified to drop the proposed
liquidation of EP and add $1.00 in cash for each Unit exchanged.

     In September 1989, an exchange offer commenced which offered .5 share of EC
common stock and $1.00 in cash for each Unit. Upon completion of this exchange
offer, 805,914 Units, or .8% of the outstanding Units, remained held by the
Public Unitholders.

     On April 12, 1989 a class action complaint was filed in the Court of
Chancery of the State of Delaware, seeking damages in connection with the
exchange offer. Following a trial of the case, the court found that the exchange
offer prospectus did not disclose adequately the basis of the exchange ratio,
that the structure and timing of the transaction were unfair to holders of Units
and that the price paid was not a fair price. Damages of $3.42 per Unit were
awarded to the plaintiff class. The award ultimately included $41 million
additional consideration for the Units and $21 million in prejudgment and post-
judgment interest. The judgment was paid by EC in January 1994.

     In February 1994, EP announced that it would discontinue distributions to
holders of Units. EP's capital expenditures had consistently exceeded EP's cash
flow, which had remained depressed because gas and oil prices continued to be
below their levels at the time EP was organized, and borrowings to support
distributions were causing EP's debt to grow inappropriately. Thus, a principal
advantage of operating in partnership form was no longer being realized by EP or
the Public Unitholders.

     As noted above, EC initially stated that it intended, but that it was not
obligated, to invest, directly or indirectly, amounts in EP to support its cash
distributions and exploration and development expenditures at anticipated
levels. Through December 1987 the EC Companies had invested cash distributions
of approximately $387 million in return for additional Units; as a result the
number of Units outstanding had increased approximately 34% to the current level
of 102,500,076. In January 1988, in a move to halt the growth in the number of
Units outstanding, the EC Companies began to support EP's cash flow requirements
by lending funds to EP. Through September 1994 the EC Companies had loaned EP
approximately $309 million to

                                    - 21 -
<PAGE>
 
support its cash flow requirements. This debt amounts to approximately 33% of
EP's capitalization.

     Under these circumstances EEI considered whether to continue the operations
of EP. EC and its predecessors have a long history of conducting gas and oil
exploration and production activities. EEI considered that it was in the best
interests of the EC Companies and the other partners of EP to continue in the
business of owning and operating the business and properties of EP, and to
remain as part of an integrated natural gas operation. EEI also considered the
fact that it did not have any duty or obligation to offer or sell to any third
party such business and properties. EEI determined that it wanted the ownership
of the properties of EP and EPO to remain in the EC Companies, which own over a
99% interest therein through EP and EPO. EEI considered the possibility of a
liquidation of EP such that the Public Unitholders would receive cash for their
Units and the EC Companies would receive all of the properties of EP and EPO in
liquidation of their partnership interests. EEI determined that it did not want
to force the Public Unitholders to take cash for their Units because it wanted
the Public Unitholders to have the option to continue as equityholders of the
business and it wanted to maintain a publicly traded entity, and determined that
there were enough advantages to be obtained from converting EP into a
corporation to justify doing so. See "Reasons to Convert EP Into Corporate
Form." Therefore, in August 1994 EEI announced that it intended to convert EP
into a publicly traded corporation. No third party offers were solicited, made
or considered.

     In reviewing the various structures available under state law for effecting
the conversion of EP into a corporation, it was recognized that a merger of EP,
EPO and the new corporation would be the most efficient structure for
transferring ownership of EPO's assets. Merger structures other than the
structure used in the Reorganization, however, could have resulted in materially
adverse financial accounting and income tax consequences to the EC Companies,
the Public Unitholders and the new corporation. For example, the EC Companies
and the Public Unitholders could have been taxed immediately upon formation of
the new corporation on a significant amount of gain resulting from assumption of
debt of EP by the new corporation, EPPL or EPO. The income taxes that the EC
Companies and the Public Unitholders would have incurred could have been
substantial. In addition, because the EC Companies would not have assumed $395
million in principal amount of debt ($86 million of which is debt owed by EP to
EPO and thus does not appear on EP's consolidated financial statements) owed to
certain EC Companies and to Newco, plus accrued interest, under these other
merger structures, the new corporation would have had less equity capital and
substantially more debt outstanding than Newco will have after the
Reorganization, so that it would have had significantly less financial strength
and flexibility than Newco will have.

     The final structure for the Reorganization avoids the adverse consequences
described above. Approximately $395 million principal amount of debt of EP,
including approximately $86 million owed to EPO that does not appear on EP's
consolidated financial statements, plus accrued interest, will be assumed by EC
Companies, resulting in a strong financial structure and improved financial
flexibility for Newco in funding its growth. The elimination of interest expense
on $309 million of debt and the receipt of interest income on $86 million will
enhance

                                    - 22 -
<PAGE>
 
Newco's operating results and cash flows by an estimated $27 million per year
before income taxes. The EC Companies expect the following substantial favorable
tax consequences to result from the structure chosen for the Reorganization: (i)
the avoidance of tax that could have resulted under the other merger structures
from the assumption of the EP debt by the new corporation, EPPL or EPO, and (ii)
the preservation of the EC Companies' tax basis in EP through the substitution
of such tax basis into the assets distributed to the EC Companies upon the
liquidation of EP, as required by the Internal Revenue Code of 1986. It is
estimated that the Reorganization will result, under SFAS No. 109, in the
reduction of the EC Companies' deferred income tax liability by approximately
$55 million, which reflects the fact that the EC Companies are expected to pay
less in federal income taxes in the future than they would have paid if the
Reorganization had not occurred. These consequences are not available to the
Public Unitholders.

     In addition, the Public Unitholders will receive the benefit of a special
allocation in the EP Partnership Agreement that accommodates the assumption by
the EC Companies of all of EP's approximately $395 million principal amount of
outstanding indebtedness of EP ($86 million of which is debt owed by EP to EPO
and thus does not appear on EP's consolidated financial statements) owed to
certain EC Companies and to Newco, plus accrued interest, including that portion
of EP's indebtedness otherwise allocable to the Public Unitholders. This special
allocation allows the Public Unitholders to receive one share of Common Stock
for each Unit they own and will be tax free to them. See "FEDERAL INCOME TAX
CONSIDERATIONS."

     The Board of Directors of EEI proposed the ratio of exchange to be used in
the Reorganization because it does not result in any change in the relative
holdings of the Public Unitholders and the EC Companies with respect to their
ownership interests in EP. The EC Companies do not receive any additional
relative holdings as a result of assuming the $395 million of EP debt, plus
accrued interest. In addition, the Board of Directors retained Dean Witter to
render an opinion as to the fairness, from a financial point of view, of the
Reorganization, taken as a whole, to the Public Unitholders. Through these
actions EEI sought to minimize the extent to which the consideration of the
Reorganization was subject to the conflict of interest between the EC Companies
and the Public Unitholders. Nevertheless, the interests of the Public
Unitholders were not separately represented in establishing the terms of the
Reorganization. Such representation might have caused the terms of the
Reorganization to be different in some respects from those described herein.

     EEI, as the Managing General Partner of EP, believes the Reorganization,
taken as a whole, is fair to and in the best interests of EP and all of its
general and limited partners, including without limitation the Public
Unitholders. This belief is principally based upon the opinion of Dean Witter,
the fact that the relative ownership interests of the EC Companies and the
Public Unitholders with respect to EP are not changed, and the fact that the EC
Companies are assuming approximately $395 million principal amount of debt ($86
million of which is debt owed by EP to EPO and thus does not appear on EP's
consolidated financial statements) owed to certain EC Companies and to Newco,
plus accrued interest, and receiving the Equipment

                                    - 23 -
<PAGE>
 
     Leases.  EEI also considered the fact that it will no longer have any
     liability for the obligations and liabilities of EP after the
     Reorganization and will no longer have a fiduciary duty to EP and its
     partners.  EEI also considered the advantages of operating in corporate
     form mentioned above and the tax consequences to the EC Companies and to
     the Public Unitholders.  No particular weight was assigned to any one
     factor in arriving at its decision.

          Newco was organized on September 1, 1994 under the laws of the State
     of Texas for the initial purpose of becoming the successor to EP in
     corporate form in accordance with the Reorganization.  Upon consummation of
     the Reorganization, Newco will acquire all partnership interests in EPO and
     will merge EPO into Newco.  In this manner Newco will acquire EPO's assets
     and liabilities.  Newco intends to continue EP's business of gas and oil
     exploration, development and production.  Newco has conducted no business
     to date and currently has no significant assets and no employees or
     operating history.  Newco will not acquire any material assets until
     consummation of the Reorganization and has no material arrangements with EP
     other than pursuant to the Reorganization.

     Calculation of Exchange Ratio.

          The Board of Directors of EEI proposed the ratio of exchange to be
     used in the Reorganization because it does not result in any change in the
     proportionate holdings of the Public Unitholders and the EC Companies with
     respect to their ownership interests in EP.  Such ratio and the number of
     shares of Common Stock to be issued in the Reorganization were calculated
     as follows:  (i) 1,045,812 shares were attributed to EEI and EC in
     recognition of their 1% general partner interest in EPO, (ii) 1,035,354
     shares were attributed to EEI in recognition of its 1% general partner
     interest in EP and (iii) 102,500,076 shares were attributed to the limited
     partner interests in EP.  The Public Unitholders, in recognition of their
     805,914 Units (.786% of the Units), were allocated 805,914 shares (.771%)
     of the Common Stock to be issued in the Reorganization.  The .015%
     difference in the Public Unitholders' ownership of Units and Common Stock
     is due to the shares of Common Stock attributable to the general partner
     interests in EPO and EP.

          In calculating the exchange ratio, only the above analysis was
     considered.  However, in determining whether the exchange ratio, as so
     calculated, was fair, the following factors were also considered:  (i) the
     elimination of all general partner liability of EC Companies with respect
     to EP and EPO and the elimination of EEI's general partner fiduciary
     duties; (ii) the assumption by the EC Companies, and the related discharge
     of EP's liability for, the $309 million indebtedness, plus accrued
     interest; (iii) the tax consequences of the Reorganization to the EC
     Companies and to the Public Unitholders; (iv) the EC Companies assuming
     approximately $86 million of intercompany debt, plus accrued interest, owed
     by EP to EPO; and (v) the assignment to and assumption by EEI of the
     Equipment Leases and the corresponding subleasing of the related equipment
     to Newco.  EEI believes that the exchange ratio is fair to all of the
     partners of EP principally because it does not change the proportionate
     holdings of the Public Unitholders and the EC Companies with respect to
     their ownership interests in EP.  EEI did not alter the exchange ratio
     after considering the listed factors because, after considering these
     factors as a

                                    - 24 -
<PAGE>
 
     whole, EEI continued to conclude that the exchange ratio was fair to and in
     the best interests of EP and all of its general and limited partners
     because the cumulative effect of such factors and their impact on the
     Reorganization was not detrimental to any of the parties such that an
     adjustment to the exchange ratio was necessary.

     Reorganization Steps

          The Reorganization of EP involves the following steps:

          1.   Capitalization of Newco.  EP, EC and EEI will contribute their
               -----------------------                                       
     partnership interests in EPO to Newco in exchange for shares of Common
     Stock.  EPO will then be merged into Newco.  As a result, Newco will have
     all of the assets of EPO (including gas and oil properties, associated
     operating assets and working capital) and all of EPO's liabilities and
     obligations (other than the Equipment Leases and the assumed liabilities as
     described herein).  As a result of these transactions, the shareholders'
     equity of Newco will be enhanced by $395 million (before recording deferred
     federal income taxes) plus accrued interest when contrasted with the equity
     of EP, because Newco will not assume indebtedness in the principal amount
     of $309 million now owed by EP to EC Companies, and, in addition, Newco
     will hold an $86 million note receivable from EP that will be assumed by EC
     Companies.  At the end of this step, EP will hold approximately 99% of the
     Common Stock and the EC Companies will hold approximately 1% of the Common
     Stock.

          2.   Liquidation of EP.  After the merger of EPO into Newco, EP will
               -----------------                                              
     be liquidated, with (i) Common Stock being distributed to each of the
     Public Unitholders, EPPL and EEI, (ii) EC Companies assuming approximately
     $395 million in aggregate principal amount of debt of EP owed to certain EC
     Companies and to Newco ($86 million of which is debt owed by EP to EPO and
     thus does not appear on EP's consolidated financial statements) owed to
     certain EC Companies and to Newco, together with accrued interest thereon
     and (iii) EEI receiving EP's interests in, and assuming EP's obligations
     under, the Equipment Leases.  See "CERTAIN TRANSACTIONS."  The portion of
     the assumed $395 million principal amount of EP debt, excluding accrued
     interest, that corresponds with the Public Unitholders' pro rata interest
     in EP, as an economic matter, is approximately $3.1 million.

          As a result of the Reorganization, both EP and EPO will cease to
     exist.  The Public Unitholders will own approximately .8% of the
     outstanding Common Stock, and the EC Companies will own approximately 99.2%
     of the outstanding Common Stock.  See "CAPITALIZATION."

          Neither EP nor Newco has any definitive plans with respect to the sale
     of any material assets, the purchase of any material assets or the making
     of any borrowings, other than in the ordinary course of its business.

          The initial Board of Directors of Newco will be as set forth in
     "MANAGEMENT."  The officers and employees of EEI will become the officers
     and employees of Newco and will be

                                    - 25 -
<PAGE>
 
     compensated by Newco (except for certain officers that are compensated by
     EC).  Previously the costs of these officers and employees were charged to
     EP by EEI and thus there will be no change in the cost of these officers
     and employees charged to Newco as a result of the Reorganization.  The
     management cost allocation payable by Newco to EC, which became effective
     July 1, 1994, is not related to the Reorganization and will not be altered
     as a result of EEI officers and employees becoming officers and employees
     of Newco because such cost allocation relates to costs incurred solely by
     EC with respect to EC personnel, not EEI personnel.  Certain officers of EC
     will also serve as officers of Newco but they will receive no direct
     compensation from Newco.  See "CERTAIN TRANSACTIONS."  Before the
     consummation of the Reorganization, EEI will change its name to avoid
     confusion with Newco.

     The Plan of Liquidation

          Contribution of EPO Interests to Newco.  The contribution of EPO
     interests to Newco will be effected pursuant to an amendment to the EPO
     Partnership Agreement substantially in the form attached as Exhibit B (the
     "EPO Partnership Agreement Amendment").  The EPO Partnership Agreement
     Amendment has been authorized by the Board of Directors of EEI as Managing
     General Partner of EP and EPO.  The EPO Partnership Agreement Amendment
     will be deemed to have been adopted and will be effective on the date it is
     approved by certain EC Companies holding approximately 99% of the
     outstanding Units.  Such actions will constitute the approval by EP that is
     required by the EP Partnership Agreement and the EPO Partnership Agreement.
     The Public Unitholders will not be asked to vote on the EPO Partnership
     Agreement Amendment.

          The structure described below saves the complexities and costs
     associated with EPO transferring to Newco 13,308 gas and oil leases in 467
     counties and parishes in 17 states, plus numerous federal onshore and
     offshore leases, plus associated rights-of-way, easements, contracts and
     other interests.

          EP, EC and EEI will contribute their partnership interests in EPO to
     Newco in exchange for shares of Common Stock in stages pursuant to a
     Contribution of Interests Agreement attached as Appendix EPO-1 to Exhibit
     B, and EPO will merge into Newco.  The first stage will involve the
     transfer by EP through Newco of a 1% limited partnership interest in EPO to
     the capital of Enserch Newsub, Inc. ("Newsub"), a newly formed Texas
     corporation wholly owned by Newco.  Then EP will contribute the remaining
     98% limited partner interest in EPO to Newco for more Common Stock, and EC
     and EEI will contribute their general partner interests in EPO to Newco in
     exchange for Common Stock.  These transfers will be accomplished serially
     and will result in EPO continuing as a limited partnership owned by Newco
     and Newsub.  EPO and Newsub then will merge into Newco.  EPO and Newsub
     will no longer exist and EPO's properties will have passed by merger into
     Newco.

          EP's Plan of Liquidation.  EP's proposed Plan of Liquidation (the "EP
     Plan of Liquidation") and the related proposed amendments to the EP
     Partnership Agreement are attached as Exhibit C.  EEI, the Managing General
     Partner of EP, has elected to dissolve EP

                                    - 26 -
<PAGE>
 
     and has determined that the complete liquidation of EP following
     dissolution is in the best interests of EP and its partners.  EEI
     recommends that EP be liquidated following its dissolution in accordance
     with the provisions of the EP Plan of Liquidation some time after the
     merger of EPO into Newco.  The EP Plan of Liquidation will be deemed to
     have been adopted, and will be effective, on the date it is approved by EEI
     and EP, as the general partners of EP, and by certain EC Companies holding
     approximately 99% of the outstanding Units.

          After the effective date of the EP Plan of Liquidation, EP will engage
     only in those activities that are necessary or proper to wind up its
     business and affairs and to distribute its assets in accordance with the EP
     Plan of Liquidation.  Subject to the order of priorities set forth in the
     EP Partnership Agreement, upon the payment or assumption of obligations and
     the establishment of reserves as provided below, EEI, as the Managing
     General Partner, will distribute all of the Common Stock then held by or
     for the account of EP to the holders of record of Units and general partner
     interests in EP at the close of business on the liquidation record date
     selected by EEI.  The liquidating distribution of Common Stock and related
     transactions will be made as and when specified by EEI in the following
     manner:

               (a) Shares of Common Stock will be distributed in kind to all
          partners of EP as follows:

                    (i)   to the Public Unitholders, one share of Common
               Stock for each Unit held (an aggregate of 805,914 shares) pro
               rata in relation to their capital account balances on the
               liquidation record date (the distribution is designed to result
               in the Public Unitholders receiving shares of Common Stock at an
               exchange rate of one share for each Unit held, and will be made
               to the Public Unitholders at or prior to the time any
               distribution of Common Stock is made to any EC Companies on
               account of the liquidation of EP), and

                    (ii)  to EEI, EC and EPPL, an aggregate of 103,775,328
               shares, which will give them the same aggregate pro rata
               ownership in Newco as their general and limited partnership
               interests in EP and EPO represent (as a general partner of EPO,
               EC receives its shares when it contributes its EPO interest to
               Newco).

               (b) EEI and EPPL will assume an aggregate of approximately $395
          million principal amount of indebtedness of EP ($86 million of which
          is debt owed by EP to EPO and thus does not appear on EP's
          consolidated financial statements) owed to certain EC Companies and to
          Newco, plus accrued interest thereon.


                                    - 27 -
<PAGE>
 
               (c) EEI will receive EP's interests in and will assume EP's
          obligations under, the Equipment Leases.  EEI will sublease the
          equipment covered by the Equipment Leases to Newco.  See "CERTAIN
          TRANSACTIONS."

          Prior to commencing the liquidating distributions, EP will pay or
     discharge all known and admitted debts, liabilities and expenses of EP to
     the fullest extent practicable and to the extent not assumed as described
     above, and will establish reserves for any other obligations, including
     unascertained or contingent liabilities and expenses.  EEI, as the Managing
     General Partner, does not currently believe that any such reserves will be
     necessary.  Any assets remaining in EP after satisfaction of all
     obligations of EP, including payment of expenses of the Reorganization
     (which remaining assets, if any, are expected to consist of a de minimis
     amount of cash and cash equivalents), will be contributed to the capital of
     Newco for no additional consideration.

          The liquidation of EP may be terminated by EEI at any time EEI deems
     the termination to be in the best interests of EP or its partners, without
     the consent or approval of any other partners, even though the
     Reorganization already may have been implemented in part.  If the
     Reorganization were terminated, EP would still be responsible for the
     expenses incurred in connection with the Reorganization, currently
     estimated to be $1,000,000.  EP expects that the Reorganization will be
     consummated within one day after it commences on December 30, 1994.

     Comparison of EP Depositary Units and Common Stock

          The following provides a comparison of the rights associated with EP
     Depositary Units and the Common Stock:

               Units                                  Common Stock
               -----                                  ------------ 

                                     Taxation

     Under current law, EP is not a            Newco is a taxable entity with 
     taxpaying entity.  Rather,                respect to its income and gains
     each holder of Units includes             after allowable deductions and 
     his share of the income and               credits. Shareholders will have
     gain and, subject to certain              taxable income from Newco only

                                               reports to its shareholders. 

                             Certain Legal Rights

     Texas law allows a holder of              Texas law affords shareholders   
     Units to institute legal action           of a corporation similar rights  
     on behalf of the partnership (a           to bring shareholder derivative  
     partnership derivative action)            actions when the board of        
     to recover damages from a third           directors has failed to          
     party or a general partner where          institute an action against      
     the general partner has failed            third parties or directors of    
     to institute the action. In               the corporation, and class       
     addition, a limited partner may           actions to recover damages from  
     institute legal action on behalf          directors for violations of      
     of himself or all other                   their fiduciary duties.          
     similarly situated holders of             Shareholders may also have       
     Units (a class action) to                 rights to bring actions in       
     recover damages from a general            federal courts to enforce        
     partner for violations of his             federal rights. These rights are 
     fiduciary duties to the                   comparable to the rights of the  
     unitholders. Holders of Units             holders of Units.

     Reasons to Convert EP into Corporate Form

               The Reorganization will convert EP into corporate form, replacing
     all outstanding partnership interests with stock of a corporation.  EEI, as
     Managing General Partner of EP, believes there are several advantages of
     converting into corporate form at this time:

               Absence of Distributions.  EP's recent results and current
     business plan required it to conserve cash resources by discontinuing
     distributions to holders of Units after January 1994.  EP's capital
     expenditures have consistently exceeded its cash flow, which has been
     depressed because gas and oil prices continue to be below the levels that
     existed at the time EP was organized.  Historically, funds for cash
     distributions were provided from investment in additional Units by EC or
     from borrowings.  The dilution created by the investment and the level of
     borrowings required to support the cash distributions increased to a point
     that the Board of Directors of EEI, the Managing General Partner,
     determined that cash distributions should be eliminated in order to
     continue EP as a nonliquidating entity.  See "THE REORGANIZATION--
     BACKGROUND."  The EP Partnership Agreement presently provides that EEI, as
     Managing General Partner, will review EP's accounts quarterly to determine
     whether distributions are appropriate.  EEI, as Managing General Partner,
     has full discretion whether or not to make current distributions and as to
     the source of funds for such distributions.  The ability to distribute cash
     free of a second level of income tax, combined with the expectation that EP
     could sustain a policy of making large cash distributions, were the
     principal reasons EP adopted the

                                    - 34 -
<PAGE>
 
     partnership form in 1985.  Thus, as a result of the discontinuation of
     distributions, the principal advantage of operating in partnership form is
     not being realized by EP or holders of Units, and is not likely to be
     realized in the foreseeable future.  See "DIVIDEND POLICY OF NEWCO."  EEI
     believes that there are no significant advantages of operating as a
     partnership that warrant continuing EP's operations in that form.

               Tax Consequences and Tax Reporting.  If EP retained its
     partnership structure, holders of Units would be required to pay income
     taxes on income of EP despite the fact that no substantial cash
     distributions are expected to be made by EP in the foreseeable future, and,
     under current law, holders of Units may be unable to use operating losses
     of EP to offset either income from other sources or investment income of
     EP, because of basis, at risk or passive loss limitations, although such
     operating losses could be used to offset EP partnership income.  Because a
     corporation is a distinct taxable entity apart from its shareholders,
     Newco's operating losses may be used to offset Newco's operating income.
     In addition, EEI believes that the complexities of tax reporting associated
     with partnership investments are regarded as unduly burdensome for most
     Public Unitholders under current conditions.  The ownership of stock rather
     than partnership units will greatly simplify tax reporting with respect to
     an investment in EP on each Public Unitholder's individual federal and
     state income tax returns for future years.  Newco, however, will be subject
     to income taxes on its taxable income at the corporate level.

               Expansion of Potential Investor Base and Greater Access to Equity
     Markets.  EEI anticipates that the Reorganization will expand EP's
     potential investor base to include institutional and other investors who do
     not typically invest in limited partnership securities because of various
     tax and administrative reasons.  Furthermore, EP expects that Newco will
     have greater access to the public and private equity capital markets than
     EP, potentially enabling it to raise capital on more favorable terms than
     are now available to EP.  This greater access may be of particular benefit
     if Newco proposes to issue equity securities to seek additional funds for
     capital expenditures or to expand its business.  Although the issuance of
     additional equity by Newco would have the effect of diluting the equity
     interest of the former Public Unitholders, it could also result in the
     Common Stock receiving additional investor interest through increased
     review by research analysts.  Newco intends to increase the level of
     minority ownership in Newco, with the view of enabling the public market to
     value directly and more effectively its gas and oil assets.  However, it
     currently has no definitive plans to issue additional equity securities.

               Acquisition Currency.  EEI believes that current industry
     conditions may provide opportunities for EP to grow through the acquisition
     of businesses and assets which are complementary to its existing business
     at attractive prices.  In certain cases, EP may want to be able to issue
     equity interests as payment of the purchase price of such acquisitions.
     EEI believes that an equity interest in a corporation will be a more
     attractive acquisition currency than an interest in a partnership.  The
     issuance of additional equity by Newco would have the effect of diluting
     the existing equity interest of the former Public Unitholders.

               Reduced Legal Costs and Uncertainty.  While there is an extensive
     body of legal guidance with respect to corporations and their governance,
     there is no comparable body of legal guidance for publicly traded limited
     partnerships. The Reorganization should reduce legal costs inherent in
     maintaining EP as a publicly traded limited partnership and provide greater
     certainty to management with respect to a number of legal issues that are
     generally more settled with respect to corporations than publicly traded
     limited partnerships, although EC would owe fiduciary duties to Newco and
     its minority shareholders.

     Fairness Opinion

               EEI, in its capacity as Managing General Partner of EP, retained
     Dean Witter in August 1994 to render an opinion to its Board of Directors
     as to the fairness of the Reorganization, taken as a whole, to the Public
     Unitholders from a financial point of view.  Management of EEI met with
     counsel and representatives of Dean Witter on several occasions commencing
     on August 24, 1994 to review generally the issues involved in determining
     the fairness of the Reorganization from a financial point of view.

               Dean Witter was not requested to and did not make any
     recommendation to the EEI Board of Directors as to the structure or the
     terms of the Reorganization.  No limitations were imposed by the EEI Board
     of Directors upon Dean Witter with respect to the investigations made or
     procedures followed by it in rendering its opinion.

               At a meeting of the EEI Board of Directors on November 15, 1994,
     Dean Witter delivered its written opinion to the Board of Directors of EEI
     to the effect that the terms of the Reorganization, taken as a whole, were
     fair, from a financial point of view, to the Public Unitholders.  A copy of
     the opinion, which sets forth the assumptions made, matters considered and
     procedures followed by Dean Witter in rendering its opinion, is attached
     hereto as Exhibit A and incorporated herein by reference.  The summary of
     the opinion of Dean Witter set forth in this Prospectus/Information
     Statement is qualified in its entirety by reference to the full text of its
     opinion.

               In connection with the preparation of its opinion, Dean Witter,
     among other things: (i) reviewed a draft of the Registration Statement on
     Form S-4 to be filed by Newco with the Commission related to the
     Reorganization; (ii) reviewed EP's Annual Reports on Form 10-K since
     inception through December 31, 1993 and Quarterly Reports on Form 10-Q for
     the quarters ended March 31, 1994, June 30, 1994 and September 30, 1994;
     (iii) reviewed and discussed EP's Reserve Report (dated January 1, 1994)
     with representatives of DeGolyer and MacNaughton, EP's independent
     petroleum engineering firm that prepared such report (the "Reserve
     Report"); (iv) reviewed historic financial and operating results of EP
     (since its original public offering on April 23, 1985) and discussed with
     senior management of EEI and EC their business plans for Newco, including
     (a) their intention to increase the percentage ownership of Newco held by
     the public, (b) their intention to reinvest Newco's cash flow in its
     business and (c) their intention to maintain a significant ownership
     interest in Newco; (v) reviewed and discussed with management financial and
     operating projections, including certain reserve


                                    - 36 -
<PAGE>
 
     economic forecasts, provided by EEI regarding the business plans and
     prospects for Newco, including its capital expenditure program and dividend
     policy; (vi) reviewed certain financial ratios, derived from financial and
     operating data provided by EEI management, of EP and Newco on a pro forma
     basis giving effect to the Reorganization; (vii) reviewed the historical
     market prices, distributions and trading volumes of the Units; (viii)
     reviewed and contrasted the distribution rights of the Public Unitholders
     to those of certain other publicly traded partnerships offered subsequent
     to EP's original offering; (ix) analyzed the current marketplace
     receptivity for natural resource publicly traded partnerships; (x) analyzed
     the financial and operating results of certain oil and gas exploration and
     production companies which Dean Witter deemed to be reasonably similar to
     EP, and studied the marketplace for the securities, including common stock,
     of such issuers; and (xi) reviewed such other financial studies, analyses
     and investigations as Dean Witter deemed appropriate.

               In rendering its opinion, Dean Witter relied on the accuracy and
     completeness of all information supplied or otherwise made available to
     Dean Witter by EC and EEI, and Dean Witter did not independently verify
     such information or undertake an independent appraisal of the assets of EP.
     Dean Witter also relied upon the management of EEI as to the reasonableness
     of and the ability to achieve the financial forecasts (which include the
     reserve economic forecasts) of Newco provided to Dean Witter, and assumed
     that such forecasts have been reasonably prepared on a basis reflecting the
     best currently available estimates and judgments of EEI's management as to
     the future operating performance of Newco.  Dean Witter assumed that the
     Reserve Report has been reasonably prepared and reflects the best currently
     available estimates and judgments of DeGolyer and MacNaughton as to the
     reserves and future production volumes of EP.  Dean Witter also relied on
     the determination of EEI and its legal counsel as to the federal income tax
     consequences of the Reorganization as to the Public Unitholders, which is
     described in this Prospectus/Information Statement.

               At the meeting of the EEI Board of Directors on November 15,
     1994, Dean Witter presented certain quantitative and qualitative analyses
     with respect to the Reorganization, which presentation was accompanied by
     written materials.  Such analyses are summarized below.  The summary set
     forth below does not purport to be a complete description of the subjects
     discussed or the written materials presented by Dean Witter in its
     presentation to the Board in connection with the Reorganization.

               Review of Certain Assumptions of the Reorganization Proposal.
     Dean Witter reviewed certain considerations and assumptions relating to the
     Reorganization proposal, including the following:  (i) the Reorganization
     will result in EEI receiving EP's interests in, and assuming its
     liabilities under, the Equipment Leases and the EC Companies assuming $395
     million in aggregate principal amount of debt of EP owed to EC Companies
     and to Newco, plus accrued interest; (ii) shares of Common Stock
     distributed to the Public Unitholders will trade on the New York Stock
     Exchange; (iii) Common Stock will be distributed to each of the Public
     Unitholders and the EC Companies pro rata in relation to their interests in
     EP prior to the Reorganization; (iv) management intends to increase the
     percentage ownership of Newco held by the public; (v) it is the intention
     of EEI and EC management to cause Newco to utilize substantially all of

                                    - 37 -
<PAGE>
 
     its internally generated cash flow in connection with the growth of the
     corporation, although the Board of Directors may consider declaration of a
     nominal dividend primarily to increase Newco's attractiveness to certain
     institutional investors; and (vi) EC intends to maintain a significant
     ownership interest in Newco.

               Comparison of EP and Freeport-McMoRan Energy Partners.  The
     written materials included a comparison of terms, market performance and
     dividend history for EP and Freeport-McMoRan Energy Partners ("FMP"), which
     were two exploration and production master limited partnerships or publicly
     traded partnerships ("MLPs") offered within four days of each other in
     April 1985.  Freeport-McMoRan Inc., the corporate sponsor and general
     partner of FMP, provided strong distribution support to FMP's public
     unitholders, committing for a five year period to reinvest its
     distributions for partnership units in order to support the public's
     indicated distribution rate and stating its intention to cut its
     exploration program first before curtailing the public unitholders'
     distributions.  EP did not provide Public Unitholders a distribution
     support mechanism similar to, or as strong as, that provided by FMP.  While
     the financial, operating and asset characteristics differed between the two
     MLPs, the structure of the FMP distribution support mechanism was primarily
     responsible for FMP achieving a lower offering yield, or cost, at offering
     compared to EP.  This analysis was included to provide a better
     understanding of the market for exploration and production MLPs in 1985
     when EP was initially offered as well as the market receptivity at that
     time to alternative partnership security structures.

               Historical Review of EP and Pro Forma Analysis of EP and Newco.
     Dean Witter's written materials also provided a historical financial review
     of EP since its initial public offering through September 30, 1994 and
     reserve information through January 1, 1994.  Dean Witter also prepared a
     comparable analysis with financial forecasts for EP and Newco from 1994
     through 1997 based on information supplied by EC and EEI.  A comparison of
     the projected income statements for EP and Newco indicated that Newco would
     generate higher earnings compared to EP in each period analyzed.  In
     addition, comparisons of net operating cash flow indicated that Newco
     would, in the aggregate, generate a greater amount of operating cash flow
     compared to EP over the periods reviewed.  Newco would also have a more
     conservative capital structure due to the reduction in aggregate debt and a
     projected ratio of current assets to current liabilities in 1995 of 0.81x
     compared to EP's projected ratio of current assets to current liabilities
     of 0.11x in 1995.  In this analysis, Dean Witter also made adjusted net
     worth (adjusted book value) calculations on a per share basis in corporate
     and MLP form.  Adjusted net worth was calculated to value EP's proved
     reserves as of January 1, 1994 based on reported private sales of oil and
     gas assets using various pricing assumptions and to exclude deferred taxes.
     Due to the planned reduction in aggregate debt and the improvement in the
     ratio of current assets to current liabilities, the per share adjusted net
     worth values were higher in corporate than MLP form.

               Analysis of MLP Marketplace.  Dean Witter presented analyses
     pertaining to the MLP marketplace from its inception in 1982 through
     November 9, 1994, including offering statistics for each of the 127 MLP
     public offerings completed since 1982.  Dean Witter reviewed and compared
     financial characteristics of various MLPs at their initial public offerings
     and contrasted the current distribution rights of the Public Unitholders
     with those of certain other publicly



                                    - 38 -
<PAGE>
 
     traded partnerships offered subsequent to EP's initial public offering.
     Dean Witter noted that the MLP market has evolved to a point where any
     potential MLP security offering must provide terms, including distribution
     rights, which are substantially more restrictive to the issuer and
     therefore more generous to the investor than those terms provided to the
     Public Unitholders.  Dean Witter also discussed the appropriateness of such
     more generous distribution rights in the context of a commodity based
     business, like EP, which needs to reinvest most, if not all, of its cash
     flow in its operations.  Dean Witter concluded that it would be very
     difficult, if not impossible, for EP to sell MLP units in any meaningful
     amount to the public in their current structure and at their current price
     in today's marketplace.

               Analysis of Capital Markets for Gas and Oil Exploration and
     Production Companies.  Dean Witter analyzed and compared the capital
     raising efforts of gas and oil exploration and production companies
     structured in limited partnership form with those in corporate form.  Dean
     Witter noted that since 1990, exploration and production companies in
     corporate form have completed 99 public equity offerings that raised over
     $8.8 billion, compared with three offerings by exploration and production
     companies in limited partnership form that raised $113 million.  Further
     analysis also indicated that a substantial majority of exploration and
     production MLPs previously offered have either been converted into
     corporate form or have been liquidated.  Dean Witter concluded that an
     exploration and production company in today's marketplace would have a much
     higher chance of successfully completing a public equity offering in
     corporate form than in MLP form.

               Analysis of Selected Gas and Oil Exploration and Production
     Companies.  Using publicly available information, Dean Witter analyzed
     certain financial information of selected publicly traded gas and oil
     exploration and production companies (including both limited partnerships
     and corporations) which it deemed to be reasonably similar to EP.  These
     companies included five corporations (Anadarko Petroleum Corporation,
     Apache Corporation, Noble Affiliates, Inc., Parker Parsley Petroleum
     Company and Seagull Energy Corporation) and four MLPs (Kelley Oil and Gas
     Partners, Ltd., Sun Energy Partners, Hallwood Energy Partners and Samson
     Energy Co.).  Dean Witter also compared the financial attributes of EP and
     Newco to an index composed of the exploration and production companies
     followed by Dean Witter Equity Research, which included the following:
     Anadarko Petroleum Corporation, Apache Corporation, Burlington Resources,
     Inc., Cabot Oil and Gas Corporation, Enron Oil and Gas Company, The
     Louisiana Land and Exploration Co., Maxus Energy Corporation, Noble
     Affiliates, Inc., Oryx Energy Company, Parker and Parsley Petroleum
     Company, Santa Fe Energy Resources, Inc. and Vintage Petroleum, Inc.
     Financial data on EP was presented in these analyses based on its market
     price one day prior to the Reorganization announcement and as of November
     9, 1994.  Analysis of certain ratios indicated that EP's assets may achieve
     a higher valuation in corporate form.  For example, EP's market value to
     pre-tax SEC-10 value was 0.76x based on the pre-announcement unit price of
     $8.125 compared with the average of 1.17x for the five comparable
     corporations.  Market value and aggregate value (market value plus long-
     term debt) per barrel of oil equivalent of proved reserves was $6.25 and
     $8.51, respectively, for the five comparable corporations versus $3.84 and
     $5.24, respectively, for EP.  While the analysis of certain other ratios
     might indicate that EP's assets could achieve a higher valuation in limited
     partnership


                                    - 39 -

     form, Dean Witter concluded that a purely financial comparison between
     exploration and production MLPs and exploration and production corporations
     was not meaningful since there are only four publicly traded exploration
     and production MLPs other than EP, each of which has a small public float
     and small traded volume compared to the publicly traded exploration and
     production corporations; and two of those MLPs recently announced their own
     restructuring plans to convert to corporate form.  Dean Witter believes
     that a complete understanding of such comparable company analysis involves
     qualitative as well as quantitative judgments concerning similarities and
     differences between the financial operating characteristics of companies
     under review.

               Analysis of Certain Financial Ratios Derived from Financial and
     Operating Data Provided by EEI Management.  Dean Witter analyzed certain
     financial ratios and prepared other financial analyses that were derived
     from projections specifically prepared by EEI management in connection with
     the Reorganization.  Dean Witter noted that due to the reduction of $309
     million of long term debt and the creation of lease obligations resulting
     from the restructuring of the Equipment Leases as a result of the
     Reorganization, Newco would have a long term debt to capitalization ratio
     of 14%, compared to EP's long term debt to capitalization ratio of 33%
     without the Reorganization.  As a result of the lower interest expense due
     to the reduction in long term obligations and the receipt of interest
     income on the $86 million note receivable from an EC Company, Newco's
     projected cash flow from operations and net income would be similar to or
     greater than projected cash flow from operations and net income without the
     Reorganization over the periods analyzed.  Although various book value
     computations were made under different asset pricing assumptions, the
     majority of the analyses prepared by Dean Witter assumed EC would maintain
     a significant ownership interest in Newco.

               Review of Market Prices of EP, Comparable Companies and Various
     Related Indices.  Dean Witter compared the price performance of EP on an
     absolute basis and relative to indices of comparable publicly traded
     limited partnerships, including some that have either been liquidated or
     converted into corporate form, Standard & Poor's Energy Composite Index and
     an index of comparable publicly traded exploration and production companies
     followed by Dean Witter Equity Research.  The review focused on two periods
     it considered relevant:  (i) April 26, 1985 (the date of EP's initial
     public offering) to November 9, 1994 and (ii) July 1, 1994 (four weeks
     immediately preceding the public announcement of the Reorganization) to
     November 9, 1994.  This review indicated that on a relative basis EP's
     price appreciation exceeded the price appreciation of comparable
     exploration and production companies and the selected market indices for
     the period from July 1, 1994 through November 9, 1994.  Further, this
     review indicated that as of November 9, 1994, the Unit price had increased
     approximately 29% from the closing price of $8.125 on the day immediately
     preceding EP's public announcement of the Reorganization.

               Analysis of Equity Research Coverage.  Dean Witter compared
     equity research coverage for EP and the four remaining publicly traded
     exploration and production MLPs and a selected group of other well-known
     master limited partnerships with selected exploration and production
     corporations.  This analysis indicated that exploration and production
     corporations receive more


                                    - 40 -
<PAGE>
 
     research coverage than entities structured as MLPs.  The potential for
     greater research coverage, which would increase investor awareness of
     Newco's securities, would improve Newco's ability to offer its securities
     in the public marketplace in corporate rather than limited partnership
     form.

               Dean Witter believes that its analyses must be considered as a
     whole and that selecting portions of its analyses and of the factors
     considered by it, without considering all factors and analyses, could
     create a misleading view of the processes underlying its opinion.  The
     preparation of a fairness opinion is a complex process and not necessarily
     susceptible to summary description.  In its analyses, Dean Witter made
     numerous assumptions with respect to industry performance, general business
     and economic conditions and other matters.  Any estimates contained therein
     are not necessarily indicative of actual values, which may be significantly
     more or less favorable than as set forth therein.  Because such estimates
     are inherently subject to uncertainty, none of EC, EEI, Dean Witter or any
     other person assumes responsibility for their accuracy.

               EEI selected Dean Witter to give the opinion referred to above
     primarily because of Dean Witter's reputation as an investment banking firm
     with substantial experience in evaluating gas and oil companies and
     transactions.  As a part of its business, Dean Witter is continually
     engaged in the valuation of businesses and their securities in connection
     with mergers and acquisitions, negotiated underwritings, secondary
     distributions of listed and unlisted securities, private placements, and
     valuations for estate, corporate, and other purposes.  Dean Witter has not
     provided any material investment banking services to any of the EC
     Companies in the past two years.

               Pursuant to a letter agreement dated August 29, 1994, Dean Witter
     has been paid a fee of $100,000 for its services.  The fee was not
     contingent upon the consummation of the Reorganization or any other
     occurrence.  In addition, EEI and EC have agreed to reimburse Dean Witter
     for its reasonable out-of-pocket expenses and to indemnify Dean Witter
     against certain liabilities, including liabilities under the Securities Act
     and the Exchange Act, arising out of or in conjunction with its rendering
     of services pursuant to its engagement.

     No Public Unitholder Consent Required

               The consent of holders of a majority of the outstanding Units is
     necessary to approve the Reorganization.  The EEI Board of Directors has
     fixed the close of business on December 5, 1994 as the record date for the
     determination of holders entitled to notice of and to consent to the
     Reorganization.  As of that date, there were outstanding 102,500,076 Units.
     Since the EC Companies held approximately 99.2% of such Units on that date
     and intend to approve the Reorganization, approval of the Reorganization is
     assured without the consent of any other holder of Units.  ACCORDINGLY, EP
     IS NOT SOLICITING YOUR CONSENT TO THE REORGANIZATION, AND YOU ARE REQUESTED
     NOT TO SEND EP A CONSENT OR PROXY  WITH RESPECT TO THE REORGANIZATION.

     Procedure for Delivery of EP Depositary Unit Certificates

               Enclosed with this Prospectus/Information Statement is a Letter
     of Transmittal, which should be filled out by each Public Unitholder and
     returned to Harris Trust Company of New York, c/o Harris Trust and Savings
     Bank, 11th Floor, Shareholder Services, 311 West Monroe Street, Chicago,
     Illinois 60606-4607, along with all certificates representing EP Depositary
     Units possessed by such Public Unitholder.  Common Stock certificates will
     be issued in accordance with the information supplied by the Public
     Unitholder in the completed Letter of Transmittal.  The Letter of
     Transmittal contains detailed instructions regarding its completion on its
     reverse side.

               Until surrender of certificates representing their EP Depositary
     Units for exchange, Public Unitholders will not be entitled to receive any
     dividends that may be declared and payable to holders of record of Common
     Stock.  Any such dividends will be remitted to the Public Unitholders
     entitled thereto, without interest, at the time that such certificates
     representing EP Depositary Units are surrendered for exchange, subject to
     applicable abandoned property, escheat or similar law.  After consummation
     of the Reorganization, however, certificates representing EP Depositary
     Units will be deemed for all other corporate purposes to evidence ownership
     of Common Stock distributable with respect thereto.

                RELATIONSHIP BETWEEN NEWCO AND THE EC COMPANIES

     Ownership of Shares

               After consummation of the Reorganization, the EC Companies will
     own over 99% of the outstanding Common Stock.  Through this ownership, EC
     will have the ability, directly or indirectly, to control Newco.  EC, as
     the majority shareholder of Newco, will have a fiduciary obligation under
     Texas law to act in good faith and to exercise its control of Newco in a
     manner that is fair and reasonable to the other shareholders.

     Conflicts of Interest

               Certain conflicts of interest could arise as a result of the
     relationships between the EC Companies and Newco.  See "BUSINESS."  For
     example, EC Companies will purchase and market natural gas produced from
     Newco's properties.  These transactions create the potential for conflicts
     over pricing, terms of delivery and other matters.  Other conflicts may
     include the purchase of goods and services from EC Companies and involve
     operational matters such as the availability of personnel and the
     allocation of costs.  See Note 4 of the Notes to Financial Statements for
     the year ended December 31, 1993.

               A number of transactions and relationships between Newco and the
     EC Companies are contemplated and specifically authorized by Article Eleven
     ("Article Eleven") of Newco's Restated Articles of Incorporation attached
     hereto as Exhibit D, including the following:


                                    - 42 -
<PAGE>
 
          .    Any EC Company may lend funds to Newco at an interest rate that
               is not greater than the lesser of the EC Company's actual
               interest cost of the funds or the rate that Newco would be
               charged by unrelated lenders on comparable loans.  Newco may lend
               funds to EC Companies so long as Newco does not charge interest
               at a rate less than would be charged by unrelated lenders on
               comparable loans.

          .    Officers, directors, employees, attorneys and agents of Newco may
               also serve as officers, directors, employees, attorneys and
               agents of EC Companies.  In those situations, each party using
               the services will be responsible for compensation in respect of
               the services performed for it.

          .    An EC Company may provide Newco with certain services that
               include, but are not limited to, the following: accounting and
               treasury, internal audit, human resources (such as training,
               employment and salary and benefit plan administration), tax
               planning and compliance, legal, financial management, corporate
               development and planning, investor relations, information
               systems, materials management, risk and claims management, office
               services and the management of these functions.  Newco will
               reimburse each EC Company for the direct and indirect costs
               incurred in connection with the furnishing of the services to
               Newco.  Costs will be determined on a basis reasonably calculated
               to reflect the actual costs of the services performed by such EC
               Company and may include allocations based on such factors as net
               capital employed, the number of employees or percentage of time
               spent on projects and services.

          .    EC Companies may sell gas, oil, goods and services to, and may
               purchase gas, oil, goods and services from, Newco in conformity
               with the provisions of Article Eleven discussed below.  EC
               Companies are authorized to effect sales to and purchases from
               Newco on terms that have not been determined to be fair as long
               as the transaction is authorized or ratified by the Newco Board
               of Directors.

          Other transactions not specifically provided for above may occur.
     Article Eleven provides that a contract or other transaction between Newco
     and any EC Company will not be invalid because of the relationship between
     Newco and the EC Companies or because of the presence of a director,
     officer or securityholder of an EC Company at the meeting authorizing the
     contract or transaction, or such person's participation or vote in the
     meeting or authorization or in a unanimous or other written consent
     thereto, if (1) the material facts of the relationship or interest of each
     EC Company or such director, officer or security holder are known and
     disclosed, either (a) to the Board of Directors of Newco, or a committee of
     the Board of Directors, and it nevertheless authorizes or ratifies the
     contract by a majority of the directors present or (b) to the shareholders
     of Newco, and they nevertheless authorize or ratify the contract or
     transaction by a majority of the shares present, or (2) the contract or
     transaction is fair to Newco as of the time it is authorized or ratified by
     the Board of Directors or shareholders of Newco.


                                    - 43 -

          Article Eleven is intended to validate transactions between Newco and
     EC Companies effected in conformity with Article Eleven.  The effect of
     Article Eleven on the Newco directors' fiduciary duties of loyalty and
     care, however, is unclear under Texas law.

          Any EC Company may have business interests and engage in business
     activities in addition to those relating to Newco, may engage in the
     acquisition, ownership, operation and management of working,
     nonparticipating or other interests or royalties in gas and oil properties,
     and any other business or activities, including business interests and
     activities in direct competition with Newco, for their own account and for
     the account of others, and may own interests in the same properties as
     those in which Newco owns an interest, without having or incurring any
     obligation to offer any interest in those properties, business or
     activities to Newco.  However, it is expected that EC will conduct all of
     its domestic gas and oil exploration and production business through Newco,
     and therefore, EC intends to make any acquisition of domestic gas and oil
     properties through Newco.  There may be circumstances, however, in which it
     is either necessary or appropriate for EC to make an acquisition or
     undertake domestic operations without Newco's participation.  The Restated
     Articles of Incorporation of Newco provide that EC and the other EC
     Companies may at any time engage in gas and oil activities for their own
     accounts.  EP has not conducted international gas and oil operations and EC
     will continue to conduct these operations through affiliates other than
     Newco.  After the Reorganization, Newco will be provided the opportunity to
     purchase the remainder of EC's domestic gas and oil properties, which are
     presently believed by EEI to have a fair market value of $1.4 million.  The
     book value of these properties is $5.3 million.  Therefore, EC would
     receive $3.9 million less than the carrying value of the properties.  The
     $1.4 million proceeds would be credited to EC's property account under
     full-cost accounting rules and no gain or loss would be recognized for
     accounting purposes.  For tax purposes, since it has no tax basis in the
     properties EC would realize a gain equal to the proceeds and would pay
     current income taxes of $.5 million.  The Board of Directors of Newco will
     consider such decision in the ordinary course of its deliberations.  No EC
     Company intends to conduct any domestic gas and oil exploration and
     production activities following the Reorganization.

          See "CERTAIN TRANSACTIONS" for additional discussion of transactions
     between Newco and the EC Companies.


                            DIVIDEND POLICY OF NEWCO

          It is the intention of Newco to utilize substantially all of its
     internally generated cash flow in connection with the growth of the
     corporation.  Internally generated cash flow may not be sufficient to
     sustain this growth in the future, and borrowings may be utilized to fund
     cash deficiencies.  Nevertheless, the Board of Directors may consider
     declaration of a nominal dividend primarily in order to increase Newco's
     attractiveness to certain institutional investors.

(a) Net Income (Loss) and Book Value per Unit are after deduction of the general
    partners' 1% interest.
(b) For the years ended December 31, 1993, 1992 and 1991, "fixed charges"
    exceeded "earnings" by $5 million, $23 million and $53 million,
    respectively.  Results for 1991 included a $51 million noncash write-down of
    gas and oil properties and 1992 included a $16 million noncash write-off of
    an idle pipeline and shallow-water production facility from an abandoned
    offshore project.
(c) For purposes of providing a common unit of measure, natural gas, oil and
    natural gas liquids are converted to an approximate equivalent unit on the
    basis of relative energy content: one Mcf of natural gas equals 1.05 MMBtu,
    one barrel of oil equals 5.6 MMBtu and one barrel of natural gas liquids
    equals 4.2 MMBtu.

                           AND RESULTS OF OPERATIONS


     Results of Operations

          Operating income for EP closely follows fluctuations in product prices
     and volumes that are shown in the table of Selected Financial and Operating
     Data. As an independent gas and oil producer, EP's results of operations
     are dependent upon the difference between the prices received for gas and
     oil produced and the costs of finding and producing such resources. See
     "SPECIAL CONSIDERATIONS--NEWCO--VOLATILITY OF GAS AND OIL MARKETS." Gas
     reserves at December 31, 1993 constitute approximately 84% of EP's reserves
     and gas production accounts for approximately 85% of its production for the
     year 1993 on an energy equivalent basis. Accordingly, variations in gas
     prices have a more significant impact on EP than variations in oil prices.
     The average gas prices received by EP for its production ranged from a high
     of $2.32 per Mcf in the quarter ended March 31, 1994 to a low of $1.52 per
     Mcf in the quarter ended September 30, 1991.

          Oil and condensate and natural gas liquids volumes have declined since
     1989 as the result of the natural decline in production from older
     producing fields. Projected oil production in 1995 and future years,
     because of the Garden Banks 388 project, are expected to be significantly
     above current levels. The decline in natural gas liquids production results
     from EPO's election not to extract natural gas liquids when allowed by
     contract due to low product prices and the decline in production from a
     major South Texas field. Natural gas production in 1994 should approximate
     1993 production, while 1995 production is expected to decline moderately.

          For the nine months ended September 30, 1994, EP had net income of
     $8.0 million, compared with $2.7 million for the 1993 period, reflecting a
     decrease in operating expenses and a 20% reduction in interest costs. Nine-
     month operating income of $23 million was 7% higher than the same period of
     1993. Year-to-date revenues were slightly less than the year ago period.
     Natural gas revenues were up 6% due to improvement in the average sales
     price, as sales volumes were virtually the same as the year-earlier period.
     Oil revenues decreased 18% due to declines in both prices and sales
     volumes. Costs and expenses for the first nine months were $3.1 million
     less than the 1993 period, with 1994 results reflecting a $2.0 million
     credit associated with the reversal by an appellate court of an adverse
     lower court judgment and settlements of other litigation. The decrease in
     interest expense for the nine months was primarily due to the refinancing
     of the affiliated debt at a lower interest rate.

          EP had a net loss of $4 million for the full year 1993, compared with
     a loss of $20 million in 1992 and a loss of $50 million in 1991. The 1992
     loss included a $16 million write-off of an idle pipeline and shallow-water
     production facility from an abandoned offshore project, and 1991 results
     included a $51 million noncash charge for a write-down under the "ceiling
     test" for the "full cost" method of accounting. Excluding the write-downs,
     EP's 1993 net loss was about the same as in 1992 and compares with income
     of $1.8 million in 1991.

          Excluding the write-downs, operating income for 1993 was $26 million
     versus $16 million in 1992 and $21 million in 1991. The improvement
     resulted from significantly increased natural gas prices and higher sales
     volumes. Revenues for 1993 of $185 million were 12% higher than 1992 and 6%
     above 1991.

          Natural gas revenues were $145 million in 1993, compared with $117
     million for 1992 and $122 million for 1991. The average natural gas price
     per thousand cubic feet ("Mcf") in 1993 was $2.09, up 15% from $1.82 in
     1992 and 19% from $1.76 in 1991. Natural gas sales volumes in 1993 of 69
     billion cubic feet increased 7% from the 1992 level and were virtually the
     same as in 1991. The increase in volumes for 1993 was principally due to
     accelerated natural gas development drilling in East Texas and offshore
     production from Mississippi Canyon Block 441 in the Gulf of Mexico, which
     went on stream in the second quarter of 1993.

          Variable-priced sales, which include monthly and long-term contract
     sales, covered about 75% of 1993 gas sales, compared with 80% in 1992 and
     80% in 1991. During the first nine months of 1994, the percentage of
     variable-priced gas sales was about 75%, and the percentage is expected to
     continue in this proportion for the remainder of the year.

          Oil revenues were $34 million in 1993, compared with $41 million in
     1992 and $49 million in 1991. The average sales price per barrel for 1993
     of $17.20 was 10% below 1992 and 16% under 1991. Oil sales volumes for 1993
     were 2.0 million barrels ("MMBbls"), an 8% decline from the 1992 level
     which was down 11% from the 1991 level. The lower volumes in 1993 were
     primarily the result of declining production from several North Texas
     reservoirs.

          Excluding the previously noted write-downs, costs and expenses for
     1993 were $159 million, compared with $150 million in 1992 and $153 million
     in 1991. The increase in expenses for 1993 reflects provisions totaling
     $7.1 million for pending litigation. Also, depreciation and amortization
     expense for 1993 of $77 million was $1.6 million higher than 1992,
     primarily due to increased production. The overall rate of amortization was
     $.91 per million British thermal units ("MMBtu") produced for both 1993 and
     1992, compared with $.83 in 1991. Costs of additional offshore projects and
     increased development costs associated with older fields largely account
     for the increase from 1991. Average production cost per MMBtu in 1993 was
     $.54, compared with $.53 in 1992 and $.56 in 1991.

          Interest expense in 1993 of $30 million was approximately $10 million
     higher than both 1992 and 1991. The increase reflects a $6 million
     provision for interest due royalty owners. A higher level of debt and less
     interest capitalized also contributed to the 1993 increase.

          EP's natural gas reserves at January 1, 1994, were 1.09 trillion cubic
     feet ("Tcf"), compared with 1.10 Tcf the year earlier, as estimated by
     DeGolyer and MacNaughton, independent petroleum consultants. Oil and
     condensate reserves, including natural gas liquids attributable to
     leasehold interest, were 38 MMBbls, virtually the same as the year-ago
     level.

          At January 1, 1994, estimated future net cash flows from EP's owned
     proved gas and oil reserves, based on average prices and contracts in
     effect in December 1993, were $2.0 billion, about the same as the year
     earlier. The net present value of such cash flows, discounted at the SEC-
     prescribed 10%, was $1.1 billion, virtually the same as the prior year.
     These discounted cash flow amounts are the basis for the SEC-prescribed
     cost-center ceiling under the full-cost accounting method. The margin
     between the cost-center ceiling and the unamortized capitalized costs of
     U.S. gas and oil properties was approximately $150 million at December 31,
     1993, and at September 30, 1994, had declined to approximately $16 million,
     based on average prices and contracts in effect in September 1994. Product
     prices are subject to seasonal and other fluctuations. A significant
     decline in prices from September 30, 1994 or other factors, without
     mitigating circumstances, could cause a future write-down of capitalized
     costs and a noncash charge against earnings.

          EP uses gas and oil swaps, collars and futures agreements to hedge
     volatile product prices for a portion (normally 30 to 70 percent) of
     anticipated future monthly gas and oil production. The purpose of these
     hedging activities is to fix the prices to be received. Under these
     agreements, EP receives or makes payments based on the differential between
     a fixed and a variable product price. These agreements are typically
     settled in cash at or prior to expiration or exchanged for physical
     delivery contracts. Realized gains and losses on hedging activities are
     deferred and included in income during the month that the related physical
     sale occurs.

          At December 31, 1993, EP had outstanding swap and collar agreements
     extending through December 1994 to exchange payments on 4,970,000 MMBtu's
     of gas and 121,000 barrels of oil on which EP had $1.4 million of net
     unrealized gains based on the difference between the strike price and the
     NYMEX futures price for the applicable trading month. At December 31, 1993
     realized gains on hedging activities of $1.4 million were deferred. The
     weighted average strike price and market price per MMBtu of natural gas was
     $2.21 and $1.99, respectively, and the weighted average strike price and
     market price per barrel of oil was $17.15 and $14.25, respectively, at
     December 31, 1993. Natural gas hedge transactions reduced gas revenues $4.1
     million in 1993 and $0.8 million in 1992. In 1993 oil hedges resulted in a
     $0.4 million increase of oil revenues.

          At September 30, 1994, EP had outstanding swaps, collars and futures
     agreements extending through December 1995 to exchange payments on
     11,250,000 MMBtu's of gas and 1,650,000 barrels of oil on which EP had $.4
     million of net unrealized gains based on the difference between the strike
     price and the NYMEX futures price for the applicable trading month. At
     September 30, 1994 realized gains on hedging activities of $1.3 million
     were deferred. The weighted average strike price and market price per MMBtu
     of natural gas was $2.02 and $1.92, respectively, and the weighted average
     strike price and market price per barrel of oil was $17.81 and $18.48,
     respectively, at September 30, 1994. Hedge transactions in the first nine
     months of 1994 increased gas and decreased oil revenues $2.1 million and
     $0.6 million, respectively, and in the first nine months of 1993 reduced
     gas revenues $3.9 million.

     Pro Forma Results of Operations of Newco

          Newco will conduct substantially the same business as was conducted by
     EP prior to the Reorganization. In the table below, EP's results of
     operations are adjusted to include the effects of (i) the assumption by EC
     Companies of $395 million in aggregate principal amount of debt of EP ($86
     million of which is debt owed by EP to EPO and thus does not appear on EP's
     consolidated financial statements) owed to certain EC Companies and to
     Newco, plus accrued interest, (ii) the 1% general partner interest in EPO,
     (iii) the changes in equipment lease terms and (iv) the allocation of
     additional management costs to Newco. EP's results are also adjusted for
     corporate income taxes that were not payable by EP, but that would have
     been paid by Newco. A summary reconciliation of EP's reported net income
     (loss) to Newco's pro forma net income (loss) is presented below.

          In connection with the Reorganization, Newco will enter into three
     sublease agreements with respect to the equipment underlying the Equipment
     Leases.  Pro forma combined future minimum lease payments for the three
     subleases are as follows (in thousands): $37,133 for 1995; $40,361 for
     1996; $41,338 for 1997; $41,764 for 1998; and $41,957 for 1999.  Over the
     life of the subleases, the costs to Newco of the assignment and assumption
     of the Equipment Leases, and the subleasing of the related equipment to
     Newco, will not be materially different from the costs that would have been
     incurred under the Equipment Leases.  See "CERTAIN TRANSACTIONS."

     Capital Resources and Liquidity

          Net cash flows from operating activities for the first nine months of
     1994 were $87 million, up 19% from $74 million a year earlier.  Investing
     activities required net cash flows of $96 million, compared with $93
     million for the same period of 1993, with an $8 million increase in
     property additions.  For the nine months ended September 30, 1994, net cash
     of $9


                                    - 52 -
<PAGE>
 
     million was required for investing activities after cash provided by
     operations.  In addition, there was an $8 million requirement for
     distributions to unitholders, and disbursements for the Garden Banks Block
     388 facilities under construction exceeded advances under leasing
     arrangements by $19 million.  These requirements were provided by an
     increase in temporary advances from EC Companies.

          Net cash flows from operating activities for the full year 1993 were
     $76 million, $12 million lower than 1992 primarily due to less cash
     provided by changes in net current operating assets and liabilities, and
     were virtually the same as in 1991.  Investing activities required net cash
     flows of $124 million, compared with $69 million in 1992 and $105 million
     in 1991.  The increase in 1993 is primarily due to a higher level of
     capital spending for natural gas and oil exploration and development
     programs.  In 1993, $48 million was required for investing activities after
     cash provided by operations, and cash of $31 million was required for the
     payment of distributions to holders of Units.  The total requirement of $79
     million was provided by an increase in borrowings from EC Companies and
     advances under leasing arrangements that temporarily exceeded disbursements
     for the facilities under construction.

          Planned property, plant and equipment additions for 1994 total $114
     million.  In addition, construction of the offshore platform and related
     facilities associated with EP's interest in the Garden Banks Block 388
     development project in the Gulf of Mexico is being financed through an
     operating lease arrangement as noted below.

          In 1992, EP entered into operating lease arrangements to provide
     financing for its portion of the offshore platforms and related facilities
     for the Mississippi Canyon Block 441 (37.5% owned) and Garden Banks Block
     388 (100% owned) projects.  A total of $34 million was required for the
     Mississippi Canyon Block 441 project, which was completed in early 1993;
     the lease was renewed in the second quarter of 1994 under terms that
     resulted in capital lease accounting treatment.  An operating lease
     arrangement is providing financing for up to $235 million for the equipment
     and facilities associated with the Garden Banks project.  The cost for the
     equipment and facilities will be greater than the amount of the current
     lease financing because of costs not originally covered by the lease, the
     addition of equipment, higher-than-expected costs for both labor and
     materials, design modifications and other factors.  Financing options for
     the additional costs are currently being evaluated, including an addition
     to the current operating lease arrangement.  The total cost of the
     equipment and facilities is expected to be approximately $280 million.

          On January 3, 1994, EP paid a quarterly distribution of $.075 per
     unit.  In February 1994, EP discontinued quarterly distributions to holders
     of Units.

          Even though inflation has abated considerably from the levels of the
     early 1980s, and was only about 2.5% in 1993, it continues to have some
     influence on EP's operations.  Most notable is that allowances for
     depreciation and amortization based on the historical cost of fixed assets
     may be insufficient to cover the replacement of some long-lived fixed
     assets.

          The impact of the Clean Air Act Amendments of 1990 (the "Clean Air
     Act") on EP cannot be fully ascertained until the regulations that
     implement the Clean Air Act have been approved and adopted.  Management
     currently believes that operating costs that will be incurred under the new
     permit fee structure, any capital expenditures associated with equipment
     modifications, and any other miscellaneous permitting costs required under
     the Clean Air Act will not have a material adverse effect on EP's results
     of operations.  Management expects the provisions of the Clean Air Act will
     increase the attractiveness of natural gas as compared with certain
     alternative fuels; however, it is impossible to quantify any increase in
     demand for natural gas, if any, that may be created by the Clean Air Act.

     New Accounting Standards

          SFAS No. 106, "Employer's Accounting for Postretirement Benefits Other
     than Pensions," which mandates the accounting for medical and life
     insurance and other nonpension benefits provided to retired employees, was
     adopted by EP effective January 1, 1993.
 
          SFAS No. 112, "Employer's Accounting for Postemployment Benefits,"
     became effective for EP in 1994.  This standard covers the accounting for
     estimated costs of benefits provided to former or inactive employees before
     their retirement.  EP receives an allocation of these benefits from EC
     which currently accrues costs of benefits to former or inactive employees
     by varying methods.  The new standard did not have a significant effect on
     results of operations or financial condition.

     Glossary

     Barrel - The unit of volume measurement used for petroleum products.
              1 barrel (Bbl) = 42 U.S. gallons.

     Barrel Equivalent - A measure used to equate an amount of natural gas with
     the same amount of energy in a barrel of oil.  Six thousand cubic feet of
     natural gas have approximately the same energy content as one barrel of
     oil.  For the purpose of providing a common unit of measure, natural gas,
     oil and natural gas liquids are converted to an approximate equivalent unit
     on the basis of relative energy content:  One Mcf of natural gas equals
     1.05 MMBtu, one barrel of oil equals 5.6 MMBtu, and one barrel of natural
     gas liquids equals 4.2 MMBtu.

     Operations

          EP was formed in 1985 to succeed to substantially all of the domestic
     gas and oil exploration and production business of EC.  After the
     Reorganization, Newco will continue the same business as EP.

          EP operates through EPO, in which EP holds a 99% limited partner
     interest and the general partners own a 1% interest.  EEI is the Managing
     General Partner and EC is the Special General Partner of EP and EPO.

          EP is engaged in the exploration for and the development, production
     and marketing of natural gas and crude oil throughout Texas, offshore in
     the Gulf of Mexico, onshore in the Gulf Coast and in various other areas in
     the United States.  Activities include geological and geophysical studies;
     acquisition of gas and oil leases; drilling of exploratory wells;
     development and operation of producing properties; acquisition of interests
     in developed or partially developed properties; and the marketing of
     natural gas, crude oil and condensate.  Production offices are maintained
     in Dallas, Houston, Athens, Bridgeport, Longview and Midland, Texas.

          EP has no officers, directors or employees.  Instead, officers,
     directors and employees of EEI perform all management and operating
     functions for EP.  At September 30, 1994, EEI employed 378 persons,
     including 33 geologists, 21 geophysicists and 19 land representatives who
     investigate prospective areas, generate drilling prospects, review
     submitted prospects and acquire leasehold acreage in prospective areas.  In
     addition, EEI maintains a staff of 55 engineers and 45 technologists who
     plan and supervise the drilling and completion of wells, evaluate
     prospective gas and oil reservoirs, plan the development and management of
     fields, and manage the daily production of gas and oil.  All of the
     employees of EEI will become employees of Newco effective January 1, 1995.
     Until that time, Newco will pay EEI for the services of the employees.  No
     employee will receive an increase in compensation as a result of the
     Reorganization.

          Variable-priced sales, which include monthly and long-term contract
     sales, covered about 75% of 1993 gas sales, compared with 80% in 1992 and
     1991.  During the first nine months of 1994, the percentage of variable-
     priced gas sales was about 75% and is expected to continue in this
     proportion for the remainder of the year.  Approximately 75% of EP's
     natural gas sales volumes (75% of gas revenues) for the year ended December
     31, 1993 and 81% of natural gas sales volumes (79% of gas revenues) during
     the first nine months of 1994 was sold to affiliated customers.  Effective
     March 1, 1993, affiliated revenues include gas sales under new contracts
     with Enserch Gas Company, a wholly owned subsidiary of EC, covering
     essentially all gas production not committed under then existing contracts.
     Affiliated purchasers do not have a preferential right to purchase natural
     gas produced by EP other than under existing contracts.  See "SELECTED
     FINANCIAL AND OPERATING DATA" for a discussion of EP's aggregate annual
     production of natural gas, oil and condensate.

          Following is a summary of EP's exploration and development activity
     during 1993 and the first nine months of 1994:
 
     Gulf of Mexico.  Offshore exploration provides EP the opportunity to
     improve its ratio of production to reserve base by the addition of gas and
     oil wells with relatively higher production rates.  State-of-the-art
     technology, including three-dimensional ("3-D") seismic, specialized
     seismic processing, and innovative well completion and production
     techniques, are being used to help accomplish these objectives.

          Mississippi Canyon Block 441, the first development project in the
     Gulf of Mexico that EP has operated, is indicative of this approach.  A 3-D
     seismic program, prior to field development, confirmed that the majority of
     the reservoir lies beneath a shipping fairway.  A production program was
     developed that involved drilling highly deviated wells under the shipping
     fairway, subsea completing the deep-water wells, and tying the wells back
     to a conventional shallow-water production platform using bundled
     flowlines.  The high-angle wells required special gravel-pack completion
     techniques.  After 17 months of production, the field has been essentially
     maintenance free, and currently produces some 63 million cubic feet
     ("MMcf") of natural gas and more than 350 barrels ("Bbls") of condensate
     per day from six wells.  The 3-D seismic on Mississippi Canyon Block 441 is
     being reprocessed, using depth

                                    - 57 -
<PAGE>
 
     migration and other state-of-the-art techniques to aid in the
     identification of deeper exploratory targets, which, if successfully
     drilled, could add to the field reserves.  EP has a 37.5% working interest
     in this project.

          The Garden Banks Block 388 project in the Gulf of Mexico remains on
     schedule, with initial production anticipated in mid-1995.  Completion of
     three pre-drilled wells (two oil and one gas condensate) will commence as
     soon as the floating facility is properly moored on location.  These
     operations should be completed by the end of 1995, followed by the drilling
     of new development wells.  Initial daily oil production rates from each
     pre-drilled oil well should be between 2,500 and 5,000 barrels of oil.  In
     July 1994, the tow out and placement of the subsea drilling and production
     template was completed.

          Also in July 1994, EP completed an agreement with Mobil Corporation
     under which Mobil has conducted an additional 3-D seismic survey over the
     unit and is participating in an exploratory well currently drilling on
     Garden Banks Block 387, which was spudded in August 1994.  Mobil has an
     option to acquire, for additional consideration, a 40% interest in the
     Garden Banks unit and in the production system.  EP, which currently owns
     100% of the project, will remain the project operator.

          A successful delineation well on Green Canyon Block 254 offshore
     Louisiana was drilled in 1994, which encountered more than 400 feet of net
     gas and oil pay below 12,000 feet.  The delineation well is an appraisal
     well to a discovery drilled in 1991 that encountered multiple sands with a
     combined thickness of more than 300 feet of net oil pay.  EP has a 25%
     working interest in prior work in the project and assumed a 100% working
     interest and operation of the sidetrack well.  EP also has a 25% working
     interest in three adjacent blocks.

     1993 Onshore.  EP participated in 78 development wells (62 net) in 1993,
     with the majority completed as gas producers in East Texas.  In East Texas,
     EP is positioned in a prolific gas-prone area which, despite its maturity,
     provides growth opportunities.  EP is one of the oldest and most active
     operators in this basin, which includes the Opelika, Tri-Cities, Whelan,
     Willow Springs, North Lansing and Freestone fields.

          In early 1993, EP initiated a 26-well program in East Texas to
     accelerate the development of natural gas reserves from the Travis Peak
     formation in the Opelika field.  The program was targeted to test new
     techniques for shortening the average life of its reserve base.  The
     project was completed in seven months yielding initial daily per well
     production rates of up to 1.8 MMcf of gas and 48 Bbls of oil.  EP has a
     100% working interest in these wells.

          EP performed additional development drilling in the Freestone field,
     where seven well completions flowed at daily rates ranging from 1.0 MMcf to
     2.3 MMcf of gas per well.  EP has 50% to 100% working interest in these
     wells.

                                    - 58 -
<PAGE>
 
          In the Bralley field in West Texas, the combined daily oil production
     rate from six wells increased to 800 Bbls from 500 Bbls following
     production optimization work. EP owns a 50% working interest in each of
     these wells.

          In South Texas, seven wells drilled and completed in the Fashing field
     flowed at daily rates of 1.2 MMcf to 2.6 MMcf of gas and 14 Bbls to 30 Bbls
     of oil per well.  Twelve wells drilled and completed in the Boonsville
     field in north central Texas resulted in daily production of .4 MMcf to 1.5
     MMcf of gas per well.

     1994 Onshore.  In the Hardeman Basin in North Texas, EP has acquired over
     120 square miles of 3-D seismic data in Hardeman and Wilbarger counties
     since December 1992, including projects currently being shot or processed.
     Since December 1993, EP has drilled four 8,000-foot producers based on this
     technology, with all wells being drilled in EP's Weatherman Area in
     Hardeman County.  The four wells potentialed at rates between 226 and 294
     Bbls of oil per day from the Mississippian formation.  EP has nearly a 100%
     working interest in these four wells.  In addition, EP participated with a
     20% working interest in a well based on 2-D seismic, which flowed at rates
     of approximately 100 Bbls of oil per day early in 1994.  For the remainder
     of 1994, EP plans to acquire an additional 30 square miles of 3-D data and
     drill seven more wells.  EP controls 81,000 gross acres and 74,000 net
     acres in the Hardeman Basin and has further 3-D shoots planned for 1995.

          In Shackelford County in Central Texas, EP has acquired approximately
     115 square miles of 3-D seismic data since mid-1993, including projects
     currently being shot and processed.  Since December 1993, EP has drilled
     five 5,000-foot Mississippian Reef producers.  The oil wells potentialed at
     rates between 22 and 160 Bbls of oil per day.  One gas well potentialed for
     2.4 MMcf and 33 barrels of condensate per day.  Initial sales from these
     wells commenced early in the third quarter of 1994, when the pipeline
     connection was completed.  EP has a 75% working interest in the wells.  For
     the remainder of 1994, EP plans to acquire an additional 30 square miles of
     3-D data and drill an additional nine wells in the area.  EP controls some
     44,000 gross and 33,000 net acres in the area and has additional 3-D
     seismic shoots planned for 1995.

          EP drilled and completed nine development wells (7.6 net) in the first
     six months of 1994.  Four wells were in the Boonsville field in north
     central Texas, two gas and two oil wells.  Daily gas production ranged from
     0.7 MMcf to 1.0 MMcf and daily oil production from 42 to 89 barrels.  EP
     has a 100% working interest in these wells.

          EP continued development in the Freestone field where three well
     completions potentialed at daily rates ranging from 1.9 MMcf to 2.6 MMcf of
     gas per well.  EP has a 73% to 82% working interest in these wells.

          Planned onshore development activity for the remainder of 1994
     includes drilling approximately 15 wells including eight outside East
     Texas.

     Competition

          Competition in the natural gas and oil exploration and production
     business is intense and is present from a large number of firms of varying
     sizes and financial resources, some of which are much larger than EP.
     Competition involves all aspects of marketing products (including terms,
     prices, volumes and length of contracts), terms relating to lease bonus and
     royalty arrangements, and the schedule of future development activity.

     Regulation

          Environmental Protection Agency ("EPA") rules, regulations and orders
     affect the operations of EP.  EPA regulations promulgated under the
     Superfund Amendments and Reauthorization Act of 1986 require EP to report
     on locations and estimates of quantities of hazardous chemicals used in
     EP's operations.  The EPA has determined that most gas and oil exploration
     and production wastes are exempt from the hazardous waste management
     requirements of the Resource Conservation Recovery Act.  However, the EPA
     determined that certain exploration and production wastes resulting from
     the maintenance of production equipment and transportation are not exempt,
     and these wastes must be managed and disposed of as hazardous waste.  Also,
     regulations issued by the EPA under the Clean Water Act require a permit
     for "contaminated" stormwater discharges from exploration and production
     facilities.

          The Oil Pollution Act of 1990 ("OPA 90") requires responsible parties
     to provide evidence of financial responsibility in the amount of
     $150,000,000 to clean up oil spills into the navigable waters of the United
     States.  The financial responsibility requirements apply to offshore
     facilities and possibly to onshore facilities in, on or under navigable
     waters.  The Mineral Management Service ("MMS") is the agency charged with
     the administration and enforcement of OPA 90.  The ultimate impact of the
     financial responsibility requirements cannot be determined until final
     regulations are issued by the MMS.  Further Congressional action on these
     requirements is also possible, and the final MMS regulations could be
     challenged in court.  The $150,000,000 requirement will not become
     effective until regulations under OPA 90 are issued, probably in 1996.  The
     insurance industry has indicated that insurance will not be available to
     evidence financial responsibility under OPA 90 as currently written.
     However, EP has qualified as a self-insurer using the "identified assets"
     test under the current $35,000,000 financial responsibility requirement
     using EP's interest in Tri-Cities Field as the identified assets.  It is
     believed that EP has sufficient assets to qualify as a self-insurer for
     $150,000,000 under the identified assets test if the current self-insurance
     test is included in the OPA 90 regulations.  However, the transfer of EP's
     assets to a publicly traded corporation might affect the ability to self-
     insure under OPA 90.  Currently the certification of self-insurance is made
     by EC on behalf of EP.  It is unclear whether the new regulations will
     allow EC to provide certification of self-insurance on behalf of a new
     publicly traded corporation which is controlled by EC, or whether Newco
     will qualify as a self-insurer on its own behalf.  Alternatively, Newco
     believes it could meet the current OPA 90 financial responsibility
     requirements by the purchase of a surety bond, although the cost of such
     bonds is generally much higher than insurance.  The availability of surety
     bonds generally could also be affected by the requirements of the final MMS
     regulations.

           Many states have issued new regulations under authority of the Clean
     Air Act, and such regulations are in the process of being implemented.
     These regulations may require certain gas and oil related installations to
     obtain federally enforceable operating permits and may require the
     monitoring of emissions; however, the impact of these regulations on EP is
     expected to be minor.

          Several states have adopted regulations on the handling,
     transportation, storage, and disposal of naturally occurring radioactive
     materials that are found in gas and oil operations.  Although applicable to
     certain EP facilities, it is not believed that such regulations will
     materially impact current or future operations.

          In the aggregate, compliance with federal and state environmental
     rules and regulations is not expected to have a material effect on  EP's
     operations.

          The Railroad Commission of Texas regulates the production of natural
     gas and oil by EP in Texas.  Similar regulations are in effect in all
     states in which EP explores for and produces natural gas and oil.  These
     regulations generally require permits for the drilling of gas and oil wells
     and regulate the spacing of the wells, the prevention of waste, the rate of
     production, and the prevention and cleanup of pollution and other
     materials.

     Legal Proceedings

          A lawsuit was filed against EEI, EC, its utility division and EPO in
     the 348th Judicial District Court of Tarrant County, Texas in May 1989.
     Plaintiffs seek unspecified actual damages and punitive damages in the
     amount of $5 million.  Plaintiffs allege royalties were not fully paid,
     certain expenses were improperly charged against the amount of royalties
     due, negligence in the venting of gas and liquid hydrocarbons into the air,
     and breach of the duty of good faith and fair dealing by wrongfully
     concealing certain material facts concerning sales of gas from the subject
     leases to the utility division.  No environmental claim has been made by
     plaintiffs or any environmental agency with respect to the facts underlying
     this matter, nor is any such claim expected.

          A lawsuit was filed on February 24, 1987, in the 112th Judicial
     District of Sutton County, Texas, against subsidiaries and affiliates of
     EC, as well as its utility division.  The plaintiffs have claimed that
     defendants failed to make certain production and minimum purchase payments
     under a gas-purchase contract.  In this connection, the plaintiffs have
     alleged a conspiracy to violate purchase obligations, improper accounting
     of amounts due, fraud, misrepresentation, duress, failure to properly
     market gas and failure to act in good faith.  In this case, plaintiffs seek
     actual damages in excess of $5 million and punitive damages in an amount
     equal to 0.5% of the consolidated gross revenues of EC for the years 1982
     through 1986 (approximately $85 million), interest, costs and attorneys'
     fees.

          On December 26, 1989, a lawsuit was filed against EEI and EPO in the
     130th Judicial District Court of Matagorda County, Texas.  The plaintiff
     claims that the defendants breached

                                    - 61 -
<PAGE>
 
     an alleged contract to sell a working interest and net revenue interest in
     two leases located in Matagorda County.  Trial of the case resulted in a
     jury verdict in favor of the plaintiff.  Judgment was entered by the trial
     court on October 8, 1992, ordering EEI and EPO to convey the leases to the
     plaintiff and to pay damages of $3.1 million, which includes principal,
     prejudgment interest, attorneys' fees and costs.  In an opinion issued June
     23, 1994, the Corpus Christi Court of Appeals reversed the decision of the
     trial court.  The plaintiff has filed an application for writ of error with
     the Texas Supreme Court.

          In addition, EP is a party to lawsuits arising in the ordinary course
     of its business.  EEI believes, based on its current knowledge and the
     advice of counsel, that all lawsuits and claims would not have a material
     adverse effect on EP's financial condition.

     the same as 1993 actual capital expenditures.  More than half of 1994
     capital expenditures is earmarked for domestic onshore projects.  Through
     September 30, 1994, $91 million has been expended.  The exploration program
     includes a balanced mix of projects with regard to reserve potential and

     (1)  Represents the proportionate interest of EP in the gross acres under
          lease.

          EP purchased about 220,000 net acres of leasehold interests in 1993,
     26,000 of which were in the Gulf of Mexico.  In the first six months of
     1994, EP purchased about 100,000 net acres, 39,000 of which were in the
     Gulf of Mexico.  At June 30, 1994 EP's Gulf of Mexico holdings totaled some
     129,000 net acres, with an average working interest of 43% in 60 leases and
     an overriding royalty interest in seven other leases.  EP operates 24
     leases. EP also canceled and/or allowed to expire nineteen Gulf of Mexico
     leases during 1994.  These either had been condemned by drilling on or near
     them, or had been judged, after geophysical and geological studies, to have
     insufficient potential to merit drilling.

          EP plans further drilling on undeveloped acreage but at this time
     cannot specify the extent of the drilling or predict how successful it will
     be in establishing commercial reserves sufficient to justify retention of
     the acreage.  The primary terms under which the undeveloped acreage can be
     retained by the payment of delay rentals without the establishment of gas
     and oil reserves expire 8% in 1994, 17% in 1995, 34% in 1996, 15% in 1997,
     7% in 1998, 10% in 1999 and 9% thereafter.  A portion of the undeveloped
     acreage may be allowed to expire prior to the

                                    - 64 -
<PAGE>
 
     expiration of primary terms specified in this schedule by nonpayment of
     delay rentals.  Aside from Texas and the Gulf of Mexico, EP has no material
     concentration of undeveloped acreage in single areas at this time.

          EP participated in 109 wells (79 net) during 1993.  Of these wells, 83
     (64 net) were successfully completed, resulting in a net success rate of
     81%.  Of the successful wells, seven wells (four net) were exploratory and
     76 wells (60 net) were development.

          In the first nine months of 1994, EP participated in 69 wells (48
     net).  Of these wells, 38 (30 net) were successfully completed, resulting
     in a net success rate of 63%.  Of the successful wells, 10 wells (9 net)
     were exploratory and 28 wells (21 net) were development.  At September 30,
     1994, EP was participating in 30 wells (18 net), which were either being
     drilled or in some stage of completion.

          In the 1993 drilling program, 16 wells (4.9 net) were offshore.  Of
     these wells, nine (2.6 net) gas wells and one (.1 net) oil well were
     successfully completed.  During 1992, four (1.6 net) offshore wells were
     drilled of which two (.8 net) gas wells were successfully completed.  In
     the first six months of 1994, three wells (0.8 net) were offshore.  Of
     these wells one (0.1 net) gas well and one (0.4 net) oil well were
     successfully completed.

          At December 31, 1993, EP owned working interests in 1,303 (980 net)
     gas wells and 1,121 (277 net) oil wells.  Of these, 173 (141 net) gas wells
     and 37 (32 net) oil wells were dual completions in single boreholes.

     Note:  Productive wells are either producing wells or wells capable of
            commercial production, although currently shut-in.

          The number of wells drilled is not a significant measure or indicator
     of the relative success or value of a drilling program because the
     significance of the reserves and economic potential may vary widely for
     each project.  It is also important to recognize that reported completions
     may not necessarily track capital expenditures, since  the Commission's
     guidelines do not allow a well to be reported as complete until it is ready
     for production.  In the case of offshore wells, this may be several years
     following initial drilling because of construction of platforms, pipelines
     and other necessary facilities.

                                   MANAGEMENT

     Directors and Executive Officers

          EP is managed by EEI, as Managing General Partner, and Public
     Unitholders have no power to direct or participate in the management of
     either EP or EPO.  EP does not have any directors, officers or employees.
     In place of directors, officers and employees, EEI and EC perform all
     management functions for EP.  The executive officers of EEI will be the
     executive officers of Newco upon completion of the Reorganization.

          Newco's initial Board of Directors currently consists of two members,
     described below, who will serve until the first annual meeting of Newco's
     shareholders.  Officers are elected annually by the Board of Directors.

     will pay to its Chief Operating Officer and the other executive officers
     who will devote substantially their full time to Newco and whose annual
     compensation exceeds $100,000.

          Any bonus, stock option, long-term compensation or other compensation
     to be paid by Newco to Messrs. Junco, Kincheloe and Irani after the
     Reorganization will be determined by the Compensation Committee of the
     Newco Board of Directors after the Reorganization.  Such items of
     compensation have not been determined at this time.  During 1994, Messrs.
     Junco, Kincheloe and Irani received bonuses for services rendered during
     1993 to EEI, of $95,000, $66,000 and $13,736, respectively.

          D.W. Biegler, Chairman and Chief Executive Officer of Newco and S.R.
     Singer, Chief Financial Officer of Newco, each are employed and will
     continue to be employed in identical positions with EC and each are
     directly paid all of their compensation by EC.  It is not presently
     anticipated that D.W. Biegler or S.R. Singer will receive any direct
     compensation from Newco in 1995.  The current salaries of D.W. Biegler and
     S.R. Singer are $550,000 and $347,000, respectively.  All other cash
     compensation (including bonus) paid by EC during 1994 under plans currently
     in effect for services rendered in 1993 for D.W. Biegler and S.R. Singer
     totaled $218,489 and $102,636, respectively.  It is anticipated that in
     1995 none of D.W. Biegler's compensation and less than $100,000 of S.R.
     Singer's compensation will be allocated from EC to Newco under the
     management cost allocation or under any other arrangement.

          None of the executive officers of Newco listed above, or any other
     officer or employee of Newco, will  receive an increase in his total
     compensation as a result of the Reorganization.

          Employee Benefit Plans

          Directors and executive officers of EEI have previously been included
     in employee benefit plans of EC.  It is anticipated that those individuals
     will remain under the EC employee benefit plans immediately following the
     Reorganization.  Newco does not currently have any employee benefit plans,
     other than the Plan, which is described below.  It is possible that after
     the Reorganization Newco will adopt other employee benefit plans sponsored
     by EC.

          The Stock Option Plan

          The Plan provides for the issuance of stock options ("Options") to
     officers and other key employees to purchase shares of Common Stock and the
     award to officers of shares that are subject to vesting based on the
     achievement of performance criteria ("Restricted Stock").  Under the Plan,
     (a) the option price may not be less than the fair market value of the
     shares on the date of grant, (b) options are exercisable in stages of 25%
     after one year to 100% after four years and (c) options may not be
     exercised after ten years from the date of grant.

          The Plan covers a maximum of 2,000,000 shares of Common Stock, subject
     to adjustment in the event of certain changes in the capital structure of
     Newco.  Such shares may be authorized but unissued shares or shares held in
     Newco's treasury.  If an Option or an award of Restricted Stock is
     forfeited (where the forfeiting participant received no benefits of
     ownership), expires or terminates before being exercised, the shares
     covered thereby will be

                                    - 70 -
<PAGE>
 
     available for subsequent Option or Restricted Stock awards within the
     maximum number stated above.

          An award of Restricted Stock may be granted under the Plan, either at
     no cost to the recipient or for such cost as may be required by law or
     otherwise as determined by the Compensation Committee of the Board of
     Directors.  The terms and conditions of the Restricted Stock will be
     specified at the time of the grant.  Restricted Stock may not be disposed
     of by the recipient until the restrictions specified in the award expire.
     The Compensation Committee will determine at the time of the award what
     rights, if any, the person to whom an award of Restricted Stock is made
     will have with respect to Restricted Stock during the restriction period,
     including the right to vote the shares and the right to receive any
     dividends or other distributions applicable to the shares.

                               SECURITY OWNERSHIP

          The following table sets forth information regarding the beneficial
     ownership of EP.  No director or executive officer of EC or EEI owns any

                              CERTAIN TRANSACTIONS

     Allocations

          Prior to July 1, 1994, EP was charged for the general and
  administrative staff costs incurred by EC in performing accounting, treasury,
  internal audit, income tax planning and compliance, legal and other functions,
  but was not charged for the cost of higher level management (i.e. all of the
  elected officers of EC) of these functions.  The staff costs are allocated to
  EP on such factors as net capital employed, the number of employees and
  percentage

                                    - 71 -
<PAGE>
 
  of time spent.  Such charges by EC amounted to approximately $1.8 million,
  $1.9 million, $2.0 million and $1.1 million in 1991, 1992, 1993 and the nine
  months ended September 30, 1994, respectively.  Effective July 1, 1994, EC
  began charging all of its affiliates, including EP, for the cost of management
  by higher level EC personnel of these functions, and such cost allocation to
  EP from EC was $.2 million for the third quarter of 1994.  Prior to 1994, EC
  did not charge its affiliates for the allocated cost of management from EC
  because the amounts involved were not considered material to any specific
  business segment since they involved management of several business segments.
  During 1993, EEI and the other affiliates of EC eliminated positions that had
  performed management of these functions, which are now undertaken by EC
  management personnel.  Also, a reorganization of EC, the last step of which
  was only recently concluded, resulted in divestment of two major business
  segments as well as elimination of several foreign operations.  Thus, EC had
  fewer business segments over which to spread management costs, and the costs
  became material to the remaining segments.  The management cost allocation to
  Newco (currently estimated to be approximately $1 million annually) is
  calculated in accordance with the guidelines set forth in Article Eleven of
  Newco's Restated Articles of Incorporation.  There is no written agreement
  regarding this arrangement or any other services to be provided.  See
  "MANAGEMENT--EXECUTIVE COMPENSATION."

          This management cost allocation would be charged to EP regardless of
  whether the Reorganization were proposed.  The EP Partnership Agreement
  presently provides that EEI is entitled to reimbursement for its direct and
  allocated expenses incurred in connection with EP, although it is not entitled
  to compensation for its services as Managing General Partner.    The EP
  Partnership Agreement presently provides that all items of gain, loss and
  deduction, for purposes of maintaining the partners' capital accounts, are
  allocated in accordance with partnership interests.  The EP Partnership
  Agreement also presently provides that current distributions, if made, are
  made in accordance with partnership interests.  Allocations and distributions
  are made according to partnership interests, and do not take into account the
  management functions of EEI.

          There will be no cash or other distributions made by Newco to any of
  the EC Companies that are not made to the other shareholders of Newco.

  Restructuring of Equipment Leases

          The equipment and facilities being used by EP in developing and
  producing reserves in the Mississippi Canyon Block 441 Project ("MC 441") and
  Garden Banks Block 388 Project ("GB 388") are being financed under (i) a
  Master Lease Agreement dated as of April 30, 1992, between CIBC Leasing, Inc.,
  certain financial institutions and EPO, relating to offshore production and
  related equipment for the MC 441 project, and (ii) the Master Lease Agreement
  dated as of September 30, 1992, between State Street Bank and Trust Company of
  Connecticut, National Association, Trustee, and EPO, relating to offshore
  production and related equipment for the GB 388 project (such leases, together
  with approximately $12.2 million of associated equipment to be financed
  pursuant to a modification thereof, the "Equipment Leases").  The lessors' net
  book value of the leased equipment at September 30, 1994 under the Equipment

                                    - 72 -
<PAGE>
 
  Leases is approximately $32 million for MC 441 and $235 million for GB 388.
  EC fully guarantees EPO's obligations under these arrangements.  In connection
  with the Reorganization, all rights and obligations under the Equipment Leases
  will be assigned to and assumed by EEI, with Newco entering into sublease
  arrangements, with purchase options, with EEI.  The net economic benefit to
  EEI of the assignment of the Equipment Leases is estimated to be approximately
  $12.2 million.  The portion of this sum attributable to the Public
  Unitholders, as an economic matter, is approximately $96,000.  These assets
  will be assigned to EEI in connection with the assignment and assumption of
  the Equipment Leases to EEI and will be subleased to Newco as part of the
  subleases described below.

          The total cost for the GB 388 equipment and facilities will be greater
  than the amount of the current lease financing because of costs not originally
  covered by the Equipment Lease, the addition of equipment, higher than
  expected costs for both labor and materials, design modifications and other
  factors.  The EC Companies and EPO are currently evaluating financing options
  for the additional costs, including an addition to the existing lease
  arrangement.  The total cost of the equipment and facilities is expected to be
  approximately $280 million.

          The equipment and facilities needed to develop MC 441 and GB 388 will
  be utilized by  Newco under new sublease arrangements with EEI (collectively,
  the "Equipment Subleases").  The Equipment Subleases will provide Newco with
  more financial flexibility for longer terms than the Equipment Leases.  Newco
  will have options under the Equipment Subleases to (i) purchase the subleased
  equipment at fixed prices based on projected fair market value as of the end
  of the Equipment Sublease term or (ii) extend the Equipment Subleases, for
  additional five year periods, on terms set at fair market value determined as
  of the date of extension.  The Equipment Leases and Equipment Subleases each
  contain fixed price purchase options and options to extend the lease on terms
  set at fair market value determined at the dates of extension (new leases), or
  each can be terminated at the expiration of the lease term.  The Equipment
  Subleases also provide that in the event the Equipment Subleases terminate
  without Newco having exercised its renewal or purchase options, or as a result
  of Newco's default thereunder, EEI will have the option to purchase Newco's
  interest in the MC 441 and GB 388 units at a purchase price equal to the fair
  market value thereof as of the date of purchase.  The Equipment Leases, if
  terminated, require a guaranteed residual payment while the Equipment
  Subleases do not.  A component of the payments to be made by Newco under the
  Equipment Subleases will be based on a floating interest rate of LIBOR plus
  1.75% per annum (the "Applicable Rate"), which includes a charge of 1% per
  annum to compensate the EC Companies for (i) the use of their credit, (ii) the
  fact that the terms of the Equipment Subleases will be longer than the terms
  of the Equipment Leases, and (iii) the assumption by EEI of residual value
  risk in connection with Newco's options to purchase the subleased equipment.

          The MC 441 Equipment Sublease will provide for payments by Newco of
  approximately $4.5 million annually for five years, based on an estimate of
  the Applicable Rate.  Newco will have an option to purchase the subleased
  equipment for approximately $5 million at the end of the five-year term.

                                    - 73 -
<PAGE>
 
          The GB 388 equipment will be subleased under two Equipment Subleases,
  one covering the floating production facility (the "FPF Sublease") and the
  other covering the subsea equipment, pipeline and shallow water production
  facility (the "Subsea Sublease").  The FPF Sublease will have a term of 20
  years and will provide for payments by Newco of approximately $12.6 million
  annually, based on an estimate of the Applicable Rate.  At the end of the
  fifth year of the FPF Sublease, Newco will have an option to purchase the
  subleased equipment for its then fair market value, estimated to be
  approximately $124 million, and at the end of the seventh year EEI will have
  the right to require Newco to purchase the subleased equipment for its then
  fair market value, estimated to be approximately $117 million.  If neither of
  the events referred to in the preceding sentence has occurred by the end of
  the twenty-year term, Newco will have an option to purchase the subleased
  equipment for approximately $34 million.  The Subsea Sublease will have an
  initial term of 12 years and will provide for payments by Newco of
  approximately $19 million annually, based on an estimate of the Applicable
  Rate.  Newco will have an option to purchase the subleased equipment for
  approximately $46 million at the end of the sublease term.

          Newco believes that the assignment and assumption of the Equipment
  Leases, and the subleasing of the related equipment to Newco, including the
  costs associated with the Applicable Rate, are on terms no less favorable than
  could be obtained from unrelated parties.

  Other

          Both EP and EPO maintain separate short-term borrowing arrangements
  with EC to meet operating needs.  Under these arrangements, EC may advance
  funds to EP or EPO, and EP or EPO may advance funds to EC.  EPO further
  maintains a short-term borrowing arrangement with EEI by which EEI may advance
  funds to EPO and EPO may advance funds to EEI.  Under all these arrangements,
  the aggregate amount of short-term loans available between the parties is at
  the lender's sole discretion, and any amounts advanced under the arrangements
  mature within 12 months from the date the advance is made.  The interest rate
  is the 30-day commercial paper rate available for similar amounts on
  commercial paper borrowings by EC.  Interest is payable monthly.  These
  arrangements are renewed annually.  At December 31, 1993 and September 30,
  1994, there were approximately $27 million and $55 million of net short-term
  borrowings outstanding under these arrangements, respectively.

          The EC Companies have provided long-term debt financing to EP at EC's
  borrowing cost.  The amount of such long-term debt at September 30, 1994 was
  $309 million.

          Net interest costs incurred by EP on affiliated borrowings were
  approximately $23 million, $25 million, $27 million and $18 million in 1991,
  1992, 1993 and the nine months ended September 30, 1994, respectively.

          EP had sales to affiliated companies of approximately $33 million, $33
  million, $109 million and $87 million in 1991, 1992, 1993 and the nine months
  ended September 30, 1994, respectively.  In 1993, affiliated revenues included
  gas sales of $91 million under new contracts

  effective March 1, 1993 with Enserch Gas Company covering essentially all gas
  production not committed under existing contracts.

          Newco believes that all transactions described herein are on terms no
  less favorable than could be obtained with unrelated parties.

                       FEDERAL INCOME TAX CONSIDERATIONS

     Introduction

          The following section summarizes the opinion of Jackson & Walker,
  L.L.P., special tax counsel to EP, regarding the material federal income tax
  consequences of the Reorganization that should be considered by the Public
  Unitholders.  The opinion and this summary do not, however, address or
  otherwise comment on all of the tax aspects of the Reorganization.  The
  opinion is based on the provisions of the Internal Revenue Code of 1986, as
  amended (the "Code"), existing and proposed regulations thereunder, current
  administrative rulings and court decisions, and certain factual
  representations by EC Companies and assumptions set forth herein.  There can
  be no assurance that the legal authorities on which this discussion is based
  will not change, perhaps retroactively, or that the factual representations
  and assumptions underlying the opinion will be accurate.  Counsel has relied
  upon the representations of the EC Companies without independent verification.
  Furthermore, there can be no assurance that the Internal Revenue Service (the
  "Service") will not disagree with conclusions described below, and no ruling
  from the Service on any aspect of the Reorganization has been or will be
  requested.  ACCORDINGLY, PUBLIC UNITHOLDERS SHOULD CONSULT THEIR OWN TAX
  ADVISORS AS TO THE TAX CONSEQUENCES OF THE REORGANIZATION TO THEM.

  Public Unitholders

          Pre-Reorganization Operations of EP.  The income and deductions of EP
  that accrue during the portion of 1994 prior to the Reorganization will be
  allocated among its partners, and these allocations and adjustments will be
  made in essentially the same manner as they would have been made absent the
  Reorganization.  Each Public Unitholder's capital account and tax basis in his
  Units will be adjusted by these allocations.  Each Public Unitholder will
  receive a Schedule K-1 for 1994 reflecting the income and deductions allocated
  to him for the portion of 1994 during which he was a Unitholder, even if he
  sells his Units prior to the Reorganization.

          Pre-Reorganization Sale of Units.  The tax consequences to a Public
  Unitholder who sells Units prior to the Reorganization will not be affected by
  the Reorganization.  The tax consequences of any such sale are as follows:

          (a) Character and Amount of Gain or Loss.  A Public Unitholder will
          recognize both ordinary income and capital gain or loss on a sale of
          Units.  The ordinary income component will be equal to the amount of
          ordinary income that would have been

                                    - 75 -
<PAGE>
 
          allocated to the Public Unitholder in respect of the Units that are
          sold if EP and EPO had sold all of their assets.  The ordinary income
          element if EP and EPO had sold all of their assets would be that
          amount of gain which is attributable to Section 751 assets (unrealized
          receivables and substantially appreciated inventory), including
          recapture of depreciation and intangible drilling and development
          costs.  The capital gain or loss amount will equal the difference
          between the amount realized from the sale of the Units (reduced by the
          portion resulting in ordinary income) and the Public Unitholder's
          adjusted tax basis in the Units that are sold (reduced by the portion
          allocable to the ordinary income component).  If the ordinary income
          element realized on the sale of his Units reduces the amount realized
          on the sale of his Units below his tax basis, a Public Unitholder will
          realize a capital loss on the sale portion of his Units.  A Public
          Unitholder's capital gain or loss will be treated as long-term capital
          gain or loss if the Public Unitholder owned the Units that were sold
          for more than one year prior to the sale and the Public Unitholder
          held his Units as capital assets.  If the Unitholder had a holding
          period of one year or less, the Public Unitholder's capital gain or
          loss will be treated as short-term capital gain or loss.  If a Public
          Unitholder sells less than all of his Units, for purposes of
          determining gain or loss on the Units sold, his adjusted basis in all
          of his Units held immediately prior to the sale must be allocated
          among the Units sold and Units retained based on the ratio of the fair
          market value of the Units sold over the fair market value of all his
          Units immediately before the sale.

          (b)  Suspended Deductions.

          A Public Unitholder may be limited in his ability to utilize
     previously suspended deductions and losses on a sale of his Units prior to
     the Reorganization.  Utilization of previously suspended deductions and
     losses is discussed below:

               (i)    Any losses previously allocated to a Public Unitholder
                      which he has not been allowed to use through the date of
                      sale of his Units because of the Code Section 704(d) basis
                      limitation rule will be lost and cannot be utilized to
                      offset any gain realized on the sale. Section 704(d)
                      limits the use of partnership losses to a partner's
                      adjusted basis in his partnership interest.

               (ii)   Any losses previously allocated to a Public Unitholder
                      that he has not been allowed to use because of the at-risk
                      limitations can (subject to (b)(iii) below), under
                      Proposed Regulation Sections 1.465-66 and 1.465-12, be
                      used to the extent of any gain recognized on the sale of
                      Units.

               (iii)  Any losses previously allocated to a Public Unitholder
                      that are not subject to the limitations set forth in (i)
                      or (ii) above but that he has not been allowed to use
                      because of the passive loss limitations ("suspended
                      passive losses") can be used in full if the Public
                      Unitholder sells all his Units to an unrelated person in a
                      transaction in which all gain or loss is recognized.

                                    - 76 -
<PAGE>
 
               (iv)   A Public Unitholder who sells less than all of his Units
                      will be entitled to deduct suspended passive losses to the
                      extent of any gain recognized on the sale, if the Public
                      Unitholder is a calendar year taxpayer and sells either a
                      portion or substantially all of his Units before the
                      effective date of the Reorganization in 1994. Final
                      regulations recently issued indicate that for taxable
                      years beginning after October 4, 1994, a Public Unitholder
                      will have to sell substantially all of his Units in order
                      to utilize any suspended passive losses. In addition, a
                      Public Unitholder's suspended passive losses are only
                      deductible to the extent that the gain recognized on such
                      a partial sale is allocable to passive activities. The
                      portion of any such gain that is allocable to passive
                      activities will be equal to the amount determined by
                      multiplying the Public Unitholder's gain by a fraction,
                      the numerator of which is the net gain that would have
                      been allocated to the Public Unitholder if EPO had sold
                      all of its appreciated trade or business and rental
                      activities for their fair market value and the denominator
                      of which is the amount of net gain that would have been
                      allocated to the Public Unitholder if EPO had sold all of
                      its appreciated activities, including investment
                      activities, for their fair market value. Based upon
                      representations of EEI, as Managing General Partner of EP,
                      all of the Public Unitholder's gain will be properly
                      allocable to passive activities because all of EPO's
                      appreciated assets are used in business or rental
                      activities and not investment activities.

          Reorganization Consequences.  The material federal income tax
     consequences to a Public Unitholder who receives shares of Common Stock as
     a result of the Reorganization will be as follows:

          (a) General Non-Recognition.  Public Unitholders will not recognize
          any gain or loss on the Reorganization, except as otherwise stated
          below.

          (b) Non-Recognition on Newco Contribution.  EP, EEI and EC's
          contribution of all of their partnership interests in EPO to Newco
          (the "Newco Contribution") will be tax free and will be tax-free to
          the Public Unitholders unless (i) EP's tax basis in its partnership
          interest in EPO is less than EP's share of EPO's liabilities
          transferred to Newco, as determined pursuant to Section 752 of the
          Code, in which case EP will recognize gain which will be partially
          allocated to the Public Unitholders or (ii) a Public Unitholder's tax
          basis in his Units is less than his share of EPO's liabilities, as
          determined pursuant to Section 752 of the Code, immediately before the
          Newco Contribution.  Based upon representations of EEI, as Managing
          General Partner of EP, no Public Unitholder will recognize gain on the
          Newco Contribution or the Reorganization.

          (c) Liquidation Premium Allocation.   In connection with the
          Reorganization, the EP Partnership Agreement is being amended to
          include a special allocation to the Public

                                    - 77 -
<PAGE>
 
          Unitholders of unrealized appreciation in EP's partnership interest in
          EPO (the "Liquidation Premium Allocation"), which results in positive
          capital account adjustments but has no effect on a Public Unitholder's
          tax basis.  Because of the increased value attributable to the Public
          Unitholders' Units, the assumption by the EC Companies of all of EP's
          liabilities will not reduce the Public Unitholders' exchange ratio of
          one share of Common Stock for each Unit held.  See "THE
          REORGANIZATION."  This Liquidation Premium Allocation does not result
          in any material tax consequences and will not cause the Public
          Unitholders to recognize any gain in connection with the
          Reorganization.  The assumption by the EC Companies as part of the
          Reorganization of $395 million of EP liabilities will have no tax
          consequences to the Public Unitholders or the EC Companies.

          (d) Tax Basis.  A Public Unitholder's aggregate tax basis in all
          shares of Common Stock received in the Reorganization will equal the
          Public Unitholder's aggregate tax basis in his Units, as adjusted (i)
          for 1994 operations to the date of the Reorganization and (ii) by
          excluding any share of EP debts that a Public Unitholder had
          previously included in his basis in his Units.  This basis will be
          prorated among all shares of Common Stock received by the Public
          Unitholder.  To the extent any Common Stock distributed to a Public
          Unitholder results in a tax basis lower than its fair market value,
          gain will be recognized upon the subsequent sale or other taxable
          disposition of that Common Stock.  Correspondingly, to the extent any
          Common Stock distributed to a Public Unitholder results in a tax basis
          greater than its fair market value, loss may be recognized upon the
          subsequent sale or other taxable disposition of that Common Stock.

          (e) Holding Period.  For holding period purposes, each share of Common
          Stock will be divided into two parts.  One part will be the portion of
          the value of the share that is attributable to EPO's Code Section 751
          assets that are neither capital assets nor Section 1231 assets
          (ordinary income assets).  The holding period for this part will begin
          on the day following the transfer of EPO's partnership interests.  The
          other part will include the holding period EP has in its partnership
          interest in EPO.  This other part will have satisfied the long-term
          capital gain requirement for a holding period of more than one year
          and will therefore qualify a portion of each share attributable to
          this other part for a long-term capital gain treatment when sold
          (assuming that the Common Stock is held as a capital asset).  As a
          result of this multiple holding period rule, a Public Unitholder who
          receives Common Stock in the Reorganization has to hold each share for
          at least one year to insure that all gain upon its sale will be long
          term capital gain.  The holding period that a Public Unitholder has
          for his Units is totally disregarded in determining the Public
          Unitholder's holding period for Common Stock received in the
          Reorganization.

          (f) Suspended Deductions.  Any operating loss allocated to a Public
          Unitholder in prior years or during 1994 that has not been used
          because of the at-risk limitations cannot be used since no taxable
          gain will be recognized on the Reorganization.  A Public Unitholder
          also will not be entitled to deduct suspended passive losses since no
          gain will be recognized by the Public Unitholders as a result of the
          Reorganization.  Any passive losses not used may be used thereafter
          only as provided below under "Sale of Shares."

                                    - 78 -
<PAGE>
 
          Any suspended at-risk loss not so used, and any unused loss suspended
          by a basis limitation, will be eliminated and be unavailable to Public
          Unitholders thereafter in connection with a sale of Common Stock
          received in the Reorganization.

          (g) Sale of Shares.  A Public Unitholder who receives shares of Common
          Stock in the Reorganization and thereafter sells those shares will
          recognize gain or loss equal to the difference between the amount
          realized on the sale and the Public Unitholder's tax basis in the
          shares sold.  A shareholder will be able to utilize the entire amount
          of his suspended passive losses upon the sale of all of his Common
          Stock to an unrelated person in a transaction in which all gain or
          loss is recognized.  Recently issued regulations also indicate that a
          pro rata portion of a shareholder's passive losses can be utilized to
          offset gain on the sale of Common Stock if the shareholder sells
          substantially all of his stock to an unrelated party.  Depending on
          the holding period of the Common Stock (see "Holding Period" above), a
          shareholder will realize long or short term gain or loss upon a sale
          of shares.

          (h) Ownership of Shares.  After the Reorganization, a shareholder will
          be taxed only on distributions received from Newco, if any.
          Nonliquidating distributions will be taxable as dividends to the
          extent of any current or accumulated earnings and profits of Newco.
          Any nonliquidating distributions in excess of the current or
          accumulated earnings and profits of Newco and any liquidating
          distributions will be treated as a tax free return of capital to the
          extent of the shareholder's basis in his shares of Common Stock and as
          capital gain to the extent of the excess, assuming that the shares are
          held as capital assets.  Any losses incurred by Newco will not flow
          through to shareholders for use on their income tax returns, but
          instead will be used by Newco in filing its corporate income tax
          returns.  Although, there are no statutory regulations, rulings or
          cases covering the point, counsel is of the opinion that a former
          Public Unitholder will not be entitled to use any suspended passive
          losses allocable to his shares to offset any dividends received from
          Newco.

          (i) Legislation.  Under current law, a partner recognizes gain to the
          extent that money distributed by a partnership exceeds the basis of
          his partnership interest immediately before the distribution.
          Congress, however, has recently passed legislation that will, under
          certain circumstances, treat a portion of the value of the common
          stock distributed to a partner as a distribution of money.  Absent any
          adverse regulations which apply retroactively, it appears that this
          legislation will not apply to EP's liquidating distribution of Common
          Stock to the Public Unitholders because the legislation does not apply
          to publicly traded partnership liquidations, such as the one
          constituting a part of the Reorganization, until after 1997.  No
          assurance can be given, however, that the regulations, when issued,
          will not be retroactive and apply in a materially adverse way.

     Newco

          The Newco Contribution and Merger.  The contribution by EP of a 1%
     limited partnership interest in EPO to Newco and Newco's contribution of
     that partnership interest to Newsub will both be tax free to Newco and
     Newsub.  Thereafter, the contribution by EP, EEI and EC of the remaining
     partnership interests in EPO to Newco will also be tax free to Newco
     although such contribution will constitute a constructive termination of
     EPO for federal tax purposes.  As a result of such constructive
     termination, EPO will be deemed to have distributed all of its assets and
     liabilities pro rata to Newco and Newsub, and Newco and Newsub will be
     deemed to have recontributed such assets and liabilities to a new
     partnership.  The constructive termination and re-contribution will have no
     material adverse tax consequences unless the amount of cash constructively
     distributed to Newco and Newsub exceeds their respective tax bases in their
     partnership interests.  If the cash distributed does exceed their
     respective tax bases, gain will be recognized to Newco and Newsub to the
     extent of such excess.

          The merger of EPO and Newsub into Newco will be treated as a transfer
     of assets and liabilities from EPO to Newco and from Newsub to Newco and
     the aggregate tax basis of Newco in the assets transferred will be equal to
     the tax basis that Newco and Newsub had in their respective partnership
     interests in EPO.  Newco's tax basis in a substantial portion of its assets
     will generate future tax deductions for Newco.Although Public Unitholders
     with relatively higher bases in their Units than other Public Unitholders
     may be viewed (through EP's and EPO's Code Section 754 election) as having
     a greater share of such basis, no consideration has been given to this
     expected future tax benefit in arriving at the number of shares of Common
     Stock received by each Public Unitholder.  Newco's holding period for each
     asset acquired in the Merger will equal the holding period that EPO had in
     its assets prior to the constructive termination of EPO.  See "THE
     REORGANIZATION--BACKGROUND."

          Post-Reorganization Operations.  Following the Newco Contribution, the
     income and deductions attributable to the assets and liabilities previously
     held by EPO will be included in the corporate tax return filed by Newco,
     and Newco will pay taxes on any taxable profits it recognizes from time to
     time.  Additionally, net operating losses incurred by Newco after the Newco
     Contribution and Merger will be available to offset Newco's income in
     subsequent years.

     Other Taxation

          After the Newco Contribution and Merger, Newco will also be subject to
     state and local taxes.  Counsel has not independently attempted to:

          (i)  determine the state or local tax that may be imposed on EP, EPO,
               or Newco as a result of the Reorganization; or

          (ii) determine any tax that may be imposed on a Public Unitholder by
               the country, state or other jurisdiction in which he resides or
               is a citizen.

          THE FOREGOING DISCUSSION IS INTENDED ONLY TO BE A SUMMARY OF THE
     MATERIAL FEDERAL INCOME TAX CONSEQUENCES OF THE REORGANIZATION.  PUBLIC
     UNITHOLDERS SHOULD CONSULT THEIR OWN TAX ADVISORS CONCERNING THE SPECIFIC
     FEDERAL, STATE, LOCAL AND OTHER TAX CONSEQUENCES OF THE REORGANIZATION TO
     THEM.

                        DESCRIPTION OF THE CAPITAL STOCK

          The following description of the capital stock does not purport to be
     complete and is subject to, and is qualified in its entirety by reference
     to, the more complete statements thereof set forth in Newco's Restated
     Articles of Incorporation, which have been attached as Exhibit D to this
     Prospectus/Information Statement.  Newco is currently authorized by its
     Restated Articles of Incorporation to issue 200,000,000 shares of Common
     Stock, par value $1 per share, and 2,000,000 shares of Preferred Stock of
     no par value.

     Common Stock

          Currently, 1,000 shares of Common Stock are outstanding in the name of
     EPO, solely for the purpose of authorizing Newco to do business under Texas
     law, which will be canceled in connection with the merger of EPO into
     Newco.

          Subject to the rights of the holders of any Preferred Stock that may
     be outstanding from time to time, holders of Common Stock are entitled to
     receive such dividends as are declared by the Board of Directors from any
     funds legally available therefor, to one vote for each share on all matters
     voted upon by shareholders, including election of directors (cumulative
     voting being prohibited), and to share ratably in assets available for
     distribution upon any liquidation.  Common Stock has no preemptive rights
     and is not subject to redemption or to any further call or assessment.

          Generally, holders of the Common Stock are entitled to elect all
     members of the Board of Directors and vote upon all corporate matters.
     However, any Preferred Stock that may be issued in the future may have
     voting rights.  Cumulative voting is prohibited by Newco's Restated
     Articles of Incorporation.

          The Transfer Agent and Registrar of the Common Stock will be Harris
     Trust Company of New York, New York.

     Preferred Stock

          The Common Stock will be subject and subordinate to the rights,
     privileges and preferences of any series of Preferred Stock to the extent
     set forth in the resolutions adopted by the Board of Directors establishing
     the series.  The Preferred Stock may be divided into and issued in one or
     more series as the Board of Directors of Newco may determine pursuant to
     authority vested in it by the Articles of Incorporation.  The Board of
     Directors may establish

                                    - 81 -
<PAGE>
 
     series of Preferred Stock by fixing and determining the designations,
     preferences, limitations and relative rights of the shares of the series,
     subject to and within the limitations of the Texas Business Corporation Act
     (the "TBCA") and the Restated Articles of Incorporation, including without
     limitation the following:

          (a)  the number of shares constituting the series and the distinctive
               designation of that series;

          (b)  the dividend rate on shares of the series, the dividend payment
               dates, whether dividends shall be cumulative (and, if so, from
               which date or dates), non-cumulative or partially cumulative, and
               the relative rights of priority, if any, of payment of dividends
               on the shares of the series;

          (c)  the amount payable to the holders of shares of the series upon
               any voluntary or involuntary liquidation of Newco;

          (d)  the preference in the assets of Newco over any other class,
               classes or series of shares upon the voluntary or involuntary
               liquidation of Newco;

          (e)  the redemption terms, if any, for the shares of the series;

          (f)  the provisions of the sinking fund, if any, for the redemption or
               purchase of shares of the series;

          (g)  the voting rights, if any, of the shares of the series;

          (h)  the conversion rights, if any, of the shares of the series;

          (i)  the exchange rights, if any, of the shares of the series; and

          (j)  any other special rights and qualifications, limitations or
               restrictions permitted by the TBCA to be granted to or imposed on
               the series.

          Any of the designations, preferences, limitations and relative rights
     of the shares of any series may be made dependent upon facts ascertainable
     outside the Restated Articles of Incorporation, which facts may include
     future acts of Newco, provided that the manner in which such facts shall
     operate upon the designations, preferences, limitations and relative rights
     of the shares of any series shall be set forth in the resolution or
     resolutions establishing the series.

          All shares within the same series of Preferred Stock will be identical
     except as to the date of issue and the dates from which dividends on shares
     of the series issued on different dates will cumulate, if cumulative.  The
     Board of Directors will have the authority to increase or decrease the
     number of shares within each series but may not decrease the number of
     shares within a

                                    - 82 -
<PAGE>
 
     series to less than the number of shares within that series that are then
     issued.  Preferred Stock has no preemptive rights and is not subject to any
     further call or assessment.

     Stock Ownership Restrictions

          The Mineral Leasing Act of 1920, as amended (the "Mineral Act"),
     provides that citizens of another country, the laws, customs, or
     regulations of which deny similar or like privileges to citizens or
     corporations of the United States, shall not by stock ownership, stock
     holding, or stock control, own any interest in any gas, oil or other
     mineral lease acquired thereunder.

          In order to comply with the Mineral Act and any other laws which may
     from time to time be applicable, Article Eight of Newco's Restated Articles
     of Incorporation (attached as Exhibit D) authorizes the Board of Directors
     of Newco to adopt, alter, or amend the Bylaws of Newco to add or amend such
     provisions as in their judgment may be necessary or appropriate to ensure
     that Newco and its shareholders satisfy the citizenship or other
     requirements imposed by any federal or state law for the ownership,
     possession or leasing of gas, oil or other minerals, land, or any other
     property, licenses, or rights of any nature whatsoever in which Newco or
     any of its subsidiaries may have or hereafter have, or seek to have, any
     right or interest.

          Article XV of the Bylaws of Newco restricts transfers of Newco capital
     stock to persons who are not "Eligible Citizens" (as defined), suspends
     voting, dividend and distribution rights of persons who are not Eligible
     Citizens and provides for the redemption of capital stock held by such
     persons in certain circumstances.

          "Eligible Citizen" is defined in the Bylaws as any person whose
     ownership, holding or control of Newco capital stock would not, by reason
     of such person's citizenship or the citizenship of its members or owners or
     otherwise, (i) disqualify Newco or any of its subsidiaries from owning,
     acquiring, holding, possessing or leasing oil and gas and other minerals,
     mineral deposits, lands, vessels, or other property, licenses, or rights of
     any nature whatsoever in federal lands or leases under federal laws and
     regulations in effect from time to time or (ii) violate any other
     qualifications as the Board of Directors deems in its reasonable discretion
     are necessary or appropriate to permit Newco and its subsidiaries to engage
     in any other business activities for which there may be qualifications or
     restrictions on shareholders of Newco or any of its subsidiaries under
     federal or state laws.  A person is an Eligible Citizen if the applicable
     following requirement is met:  (1) for an individual, that he is native-
     born, naturalized or a derivative citizen of the United States; (2) for a
     corporation, that it is organized or existing under the laws of the United
     States, a state, the District of Columbia or a United States territory or
     possession, that at least 75% of the ownership interest in, and the voting
     power over, the corporation is held by Eligible Citizens, that the
     corporation's president or other chief executive officer and the chairman
     of its board of directors are United States citizens and that no more than
     a minority of the number of directors required to constitute a quorum are
     non-United States Citizens; (3) for a partnership, that all of the
     interests in the partnership are owned by Eligible Citizens; (4) for a
     trust, that each of its trustees and each of its beneficiaries is an
     Eligible Citizen; and (5) for an association, joint venture or other
     entity, that all members, venturers or

                                    - 83 -
<PAGE>
 
     other equity participants are Eligible Citizens and that such association,
     joint venture or other entity is capable of holding leases or other
     interests in federal minerals or lands under the laws of the United States.

          The Bylaws further provide that any transfer, or attempted or
     purported transfer, of any Newco capital stock or interests or rights
     therein which would result in the ownership or control thereof by one or
     more non-Eligible Citizens will be void and ineffective as against Newco,
     and Newco will not recognize the transfer, provided that the shares may be
     transferred to a person who is an Eligible Citizen.  Newco capital stock
     held by non-Eligible Citizens is not entitled to dividends or other
     distributions or to vote so long as they are so held.  Further, if in the
     opinion of the Board of Directors the ability of Newco to hold any of its
     properties, leases, rights or licenses would be prohibited or restricted,
     or if Newco is named or threatened to be named in any judicial or
     administrative proceeding, because of the nationality, citizenship,
     residence or other status of any shareholder, Newco may redeem the shares
     held by the shareholder at the then current market price and upon such
     terms as shall be determined by Newco's Board of Directors.

     No Previous Market for Common Stock

          At present, there is no trading market for the Common Stock.  However,
     the NYSE has indicated to Newco that the Common Stock to be distributed to
     the Public Unitholders pursuant to the Reorganization will be approved for
     listing on the NYSE, subject to official notice of issuance.  There can be
     no assurance that an active trading market for the Common Stock will
     develop, that holders of Common Stock will be able to sell their shares at
     favorable prices or that the trading price for a share of Common Stock will
     be comparable to the trading price for an EP Depositary Unit immediately
     before the Reorganization.

                                 LEGAL MATTERS

          The validity of the Common Stock to be issued in connection with the
     Reorganization will be passed upon for Newco by Jackson & Walker, L.L.P.,
     Dallas, Texas.

                        PRO FORMA FINANCIAL STATEMENTS
                                  (Unaudited)


  The pro forma financial statements are presented based on the historical
financial statements of EP, after certain eliminations and adjustments as
described below.  Newco is a recently formed Texas corporation which will have
no substantial assets, liabilities or operations until it succeeds to the gas
and oil exploration and production business of EPO.

  EPO is the operating entity underlying EP and is 99% owned by EP.  EP's
financial statements include the operations of EPO combined with financing
activities of EP, principally related to borrowings from EC Companies for
capital expenditures and payment of distributions to Unitholders.  Newco
represents EPO in corporate form and does not include transactions relating to
EP's financing activities.

  For financial accounting purposes, the Reorganization will be treated as a
reorganization of affiliated entities.  Accordingly, the assets and liabilities
transferred to Newco from EPO will be recorded at their historical amounts.

  The pro forma balance sheet as of September 30, 1994 has been presented as if
the EPO assets and liabilities were conveyed to Newco on that date.  The pro
forma statements of operations assumes that the Reorganization occurred at the
beginning of each period presented.

  It is also contemplated that Newco will acquire, at fair value, all other
domestic gas and oil properties of the EC Companies.

  The Reorganization is more fully discussed elsewhere in this
Prospectus/Information Statement.  These unaudited pro forma financial
statements of Newco should be read in conjunction with the historical financial
statements of EP, Selected Financial and Operating Data and Managements'
Discussion and Analysis of Financial Condition and Results of Operations.  The
unaudited pro forma financial statements are not necessarily indicative of the
financial results that would have occurred had the Reorganization been
consummated on the above indicated dates, nor are they necessarily indicative of
future results.

                    NOTES TO PRO FORMA FINANCIAL STATEMENTS

 (a)   Adjustment to transfer the EC Companies 1% general partners' interest in
       the assets and liabilities of EPO in exchange for shares of Common Stock
       of Newco.

 (b)   Adjustment for certain EP assets and liabilities not being assumed by
       Newco. The principal items are $309 million of long-term debt payable to
       EC Companies, $85 million of Notes Receivable from affiliated companies
       and the assets and obligations relating to leased properties (See "THE
       REORGANIZATION").

 (c)   Effective on the transfer of EPO assets and obligations to Newco, Newco
       will enter into subleasing arrangements for offshore production
       facilities with EC Companies. One of the lease agreements will be
       accounted for as an operating lease, while two leases will be accounted
       for as capital leases with the lease obligations and related assets of
       approximately $156 million. Pro forma combined future minimum lease
       payments for the three leases are as follows (in thousands): $37,133 for
       1995; $40,361 for 1996; $41,338 for 1997; $41,764 for 1998; and $41,957
       for 1999. The operating lease has a lease term of twelve years and an
       option to purchase the equipment under lease at the end of the lease term
       at estimated fair value.

 (d)   To reflect deferred income taxes attributable to Newco. Since EP is a
       partnership, its income or loss for tax purposes is reported in the tax
       return of the individual partners. Newco, as a corporation, will be a
       taxable entity. Accordingly, the deferred tax effect of the difference in
       financial accounting basis and income tax basis of Newco's assets and
       liabilities will be recorded upon the formation of Newco.

 (e)   To reflect the organization costs and related estimated liability for
       the expenses of the Reorganization of $1,000.

     (1)  To include revenues and costs attributable to EC Companies' 1%
          interest in EPO.

     (2)  The EC Companies will assume EPO's interests in and liabilities of
          certain offshore equipment lease arrangements, and Newco will enter
          into sublease arrangements for the offshore production facilities with
          the EC Companies. One of the lease agreements will be accounted for as
          an operating lease, while the other two leases will be accounted for
          as capital leases with the lease obligations and related assets of
          approximately $156 million. (See "CERTAIN TRANSACTIONS-Restructuring
          of Equipment Leases").

     (3)  To provide for the management cost allocation to be charged by EC for
          management of certain corporate services. EP was charged and Newco
          will be charged for indirect costs (principally general and
          administrative costs) applicable to gas and oil operations. Prior to
          July 1, 1994, EP was not charged for management by EC of its
          operations including supervision of finance, accounting, tax and legal
          functions. As a separate company Newco will be charged approximately
          $1,000,000 annually to cover the cost of those functions. EP was
          charged $250 thousand for management cost allocation in the third
          quarter of 1994. (See "CERTAIN TRANSACTIONS-Allocations").

     (4)  To include interest income on the note receivable-affiliated companies
          at average balances at 7.5% interest per annum.

     (5)  To eliminate interest expense on long-term borrowings from an
          affiliated company which is not being assumed by Newco. Newco will
          benefit in that interest expense will not be incurred as a result of
          the assumption of $309 million of EP debt by EC companies in the
          Reorganization. EP incurred interest expense of $15.3 million and
          $18.2 million in the nine months ended September 30, 1994 and 1993,
          respectively, and $24.8 million for the year ended December 31, 1993
          related to such borrowings.

     (6)  To provide for income taxes on pro forma income before taxes at the
          applicable statutory federal rate.

INDEPENDENT AUDITORS' REPORT



To the Partners of Enserch Exploration Partners, Ltd.:

    We have audited the accompanying balance sheets of Enserch Exploration
Partners, Ltd. as of December 31, 1993 and 1992, and the related statements of
operations, cash flows and changes in partners' capital for each of the three
years in the period ended December 31, 1993.  These financial statements are the
responsibility of the Partnership's management.  Our responsibility is to
express an opinion on these financial statements based on our audits.

    We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

    In our opinion, such financial statements present fairly, in all material
respects, the financial position of the Partnership at December 31, 1993 and
1992, and the results of its operations and its cash flows for each of the three
years in the period ended December 31, 1993, in conformity with generally
accepted accounting principles.

                      ENSERCH EXPLORATION PARTNERS, LTD.
                         NOTES TO FINANCIAL STATEMENTS


1.  ORGANIZATION AND CONTROL

    Enserch Exploration Partners, Ltd. ("EP"), a Texas limited partnership, was
formed in 1985 to succeed to substantially all of the domestic gas and oil
exploration and production business of ENSERCH Corporation ("ENSERCH").  At
December 31, 1993, ENSERCH and Enserch Processing Partners, Ltd. ("Processing")
owned 3,112,362 (3.0%) and 98,581,800 (96.2%), respectively, of EP's limited
partnership units outstanding.  The balance of 805,914 (.8%) of EP's units
outstanding is held by the public.  For administrative convenience, EP operates
through EP Operating Limited Partnership, a Texas limited partnership ("EPO"),
formerly EP Operating Company, in which EP holds a 99% limited partner's
interest and the general partners own a 1% interest.  Enserch Exploration, Inc.
("EEI") is the managing general partner and ENSERCH is the special general
partner of EP and EPO.
 
    EP has no officers, directors or employees. Instead, officers, directors and
employees of EEI perform all management and operating functions for EP. Neither
ENSERCH nor EEI, as general partners of EP, receives any carried interests,
promotions, back-ins or other compensation.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    Basis of Presentation - The financial statements of EP have been prepared in
conformity with generally accepted accounting principles but will not be the
basis for reporting taxable income to unitholders.  The proportional
consolidation method is used whereby the financial statements reflect EP's 99%
interest in EPO's assets, liabilities and operations.  All dollar amounts except
per unit amounts in the notes to financial statements are stated in thousands
unless otherwise indicated.

    Natural Gas and Oil Hedging Contracts - Gains and losses from transactions
to hedge against volatile product prices are deferred and included in revenues
in the statements of operations during the month that the related physical sale
occurs.

    Gas and Oil Properties - The full-cost method, as prescribed by the
Securities and Exchange Commission (SEC), is used whereby the costs of proved
and unproved gas and oil properties, together with successful and unsuccessful
exploration and development costs, are capitalized. The carrying value is
limited to the present value of estimated future net revenues of proved
reserves, the cost of excluded properties and the lower of cost or market value
of unproved properties being amortized ("full-cost ceiling"). The full-cost
ceiling is calculated quarterly under current SEC rules. In March 1991, EP
recorded a $51 million noncash write-down of the carrying value of its gas and
oil properties due to the full-cost center ceiling limitation test.

    Dry-hole costs resulting from exploration activities are classified as
evaluated costs and are included in the amortization base.  Costs directly
associated with the acquisition and

                                      F-16
<PAGE>
 
evaluation of unproved properties are excluded from the amortization base until
the related properties are evaluated.  Such unproved properties are assessed
periodically and a provision for impairment is made to the full-cost
amortization base when appropriate.  Sales of gas and oil properties are
credited to capitalized costs unless the sale would have a significant impact on
the amortization rate.

    In December 1992, EP recorded a $16 million noncash write-off of an idle
pipeline and shallow-water production facility from an abandoned offshore
project.

    As a full cost company, EP assesses future site restoration, dismantlement
and abandonment costs on an overall cost center basis. At December 31, 1993,
estimates of future salvage values exceed the estimated costs of site
restoration, dismantlement and abandonment costs. Therefore, no accruals are
required.

    Depreciation and Amortization - Amortization of evaluated gas and oil
properties is computed on the unit-of-production method using estimated proved
gas and oil reserves quantified on the basis of their equivalent energy content.
Depreciation of other property, plant and equipment is provided principally by
the straight-line method over the estimated service lives of the related assets.

    Income Taxes - EP is a partnership and, as a result, the income or loss of
the partnership, which reflects differences in the timing of the deduction of
certain gas and oil drilling and development costs for federal income tax
purposes, is includable in the tax returns of the individual partners.
Accordingly, no recognition has been given to income taxes in the financial
statements of EP. The assets and liabilities reported in the financial
statements of EP exceeded the federal income-tax bases by approximately $704
million and $720 million at December 31, 1993 and 1992, respectively.

    Retirement Plan - Substantially all personnel who are associated with EP are
covered by an ENSERCH retirement plan and are eligible for certain health care
and life insurance benefits upon retirement.  Total pension costs allocated to
EP were $867, $1,054, and $929 in 1993, 1992 and 1991, respectively.  Post-
retirement health care and life insurance benefit costs allocated to EP were
$821, $550, and $577 in 1993, 1992 and 1991, respectively.  Postretirement
benefits in 1993 reflect the impact of SFAS No. 106 "Employer's Accounting for
Postretirement Benefits Other Than Pensions", effective in January 1993.  This
new standard requires the accrual of these benefits over the working life of the
employee rather than charging to expense on a cash basis.

    Fair Value of Financial Instruments - The fair values of financial
instruments has been estimated using valuation methodologies in accordance with
SFAS No. 107, "Disclosures About Fair Value of Financial Instruments".
Determinations of fair value are based on subjective data and significant
judgment relating to timing of payments and collections and the amounts to be
realized. Accordingly, the estimates presented are not necessarily indicative of
the amounts that EP could realize in a current market exchange.

                                      F-17
<PAGE>
 
    Management believes that the fair value of financial instruments, other than
long-term debt, is not materially different than the related carrying value.
The estimated fair value for long-term debt is presented in Note 3.

3.  LINE OF CREDIT AND BORROWINGS

    Short-term Borrowing Arrangements - Both EP and EPO maintain separate short-
term borrowing arrangements with ENSERCH to meet operating needs.  Under these
arrangements, ENSERCH may advance funds to EP or EPO, and EP or EPO may advance
funds to ENSERCH.  EPO further maintains a short-term borrowing arrangement with
EEI by which EEI may advance funds to EPO and EPO may advance funds to EEI.
Under all these arrangements, the aggregate amount of short-term loans available
between the parties is at the respective lender's sole discretion, and any
amounts advanced under the arrangements mature within 12 months from the date
the advance is made.  The interest rate is the 30-day commercial paper rate
available for similar amounts on commercial paper borrowings by ENSERCH.
Interest is payable monthly.  These arrangements are renewed annually.  At
December 31, 1993, there were $27,216 of net short-term borrowings outstanding
under these arrangements at an interest rate of 3.28%.

    Long-term Notes Payable - Long-term notes payable to Processing are
summarized below:

     Interest on the above notes is payable semiannually on June 30 and December
31. The estimated fair value of these notes was $352 million at December 31,
1993 and $300 million at December 31, 1992. The calculation was made using a
discounted cash flow approach based on the interest rates currently available to
ENSERCH for debt with similar terms and remaining maturities.

4.   RELATED PARTY TRANSACTIONS

     In the ordinary course of business, EP engages in various transactions with
ENSERCH and its affiliates.   All such transactions are subject to review by the
Policy and Conflicts of Interest Committee of ENSERCH, a committee composed
solely of outside directors.  The Committee has found no unfair dealings between
and among such parties.  EP is charged for direct costs incurred by ENSERCH and
EEI that are associated with managing EP's business and operations.
Additionally, indirect costs (principally general and administrative costs)
applicable to EP are allocated to EP by ENSERCH.  Such charges amounted to
$2,026, $1,927 and $1,798 in 1993, 1992 and 1991, respectively.

     EP had sales to affiliated companies (Enserch Gas Company, Lone Star Gas
Company and Processing) of $108,916, $32,508 and $32,710 in 1993, 1992 and 1991,
respectively.  In 1993, affiliated revenues include gas sales of $91,000 under
new contracts effective March 1, 1993 with Enserch Gas Company covering
essentially all gas production not committed under existing contracts.

     Net interest costs incurred on affiliated borrowings were $27,120, $25,336,
and $22,872 in 1993, 1992 and 1991, respectively.

5.   COMMITMENTS AND CONTINGENT LIABILITIES

     Advances Under Leasing Arrangements - In May 1992, EP entered into an
operating leasing arrangement to provide financing for its portion of the
offshore platform and related facilities for the 37 1/2% owned Mississippi
Canyon Block 441 project.  A total of $34 million was required for the project,
which was completed in early 1993.  EP leased the facilities for an initial
period through May 20, 1994, with an option to renew the lease, with the consent
of the lessor, for up to 10 successive six-month periods.  The lease has been
renewed through November 20, 1994 and EP expects to renew the lease for all
renewal periods.  EP has the option to purchase the facilities throughout the
lease periods and as of December 31, 1993, has guaranteed an estimated residual
value for the facilities of approximately $27 million should the lease not be
renewed.  Expenses incurred under the lease in 1993 were $2.1 million.  The
estimated future minimum net rentals for the Mississippi Canyon operating lease
are $6.3 million for 1994.

     In September 1992, EP entered into an operating lease arrangement to
provide financing for the offshore platform and related facilities of its 100%
owned Garden Banks Block 388 project.  The lessor will fund the construction
cost of the facilities quarterly, up to a maximum of $235 million.  As of
December 31, 1993, a total of $60 million had been advanced to EP

                                      F-19
<PAGE>
 
under the lease as agent for the lessors, $31 million of which was unexpended
and reflected as a current liability.  EP will lease the facilities for an
initial period through March 31, 1997, with the option to renew the lease, with
the consent of the lessor, for up to three successive two-year periods.  EP, as
agent for the lessor, will acquire, construct and operate the units of leased
property and has guaranteed completion of construction of the facilities.  EP
has the option to purchase the facilities throughout the lease periods and has
guaranteed an estimated residual value for the facilities of approximately $188
million, assuming the full lease amounts are advanced and expended, should the
lease not be renewed.  The estimated future minimum net rentals for the Garden
Banks operating lease are as follows:  $4.8 million for 1994; $9.1 million for
1995; $9.1 million for 1996; and $2.3 million for 1997.  Lease payments are
being deferred during the construction period and will be amortized when
production begins.

     At December 31, 1993, EEI had several noncancelable operating leases,
principally for buildings and office space, that expire at various dates through
1998.  EP bears an allocated share of rental expenses incurred by EEI under
noncancelable operating leases.  EP's allocated share of rental expenses (99% of
EEI's rental expenses) totaled $4,985, $3,547 and $2,938 in 1993, 1992 and 1991,
respectively.  Future minimum rentals under such leases, of which EP would bear
its proportionate share, are as follows:  $1.3 million for 1994; $1.3 million
for 1995; $1.4 million for 1996; $1.5 million for 1997; and $1.4 million for
1998.

     Legal Proceedings - A lawsuit was filed against EEI, ENSERCH, its utility
division and EPO in the 348th Judicial District Court of Tarrant County in May
1989.  Plaintiffs seek unspecified actual damages and punitive damages in the
amount of $5 million.  Plaintiffs allege royalties were not fully paid, certain
expenses were improperly charged against the amount of royalties due, negligence
in the venting of gas and liquid hydrocarbons into the air, and breach of duty
of good faith and fair dealing by wrongfully concealing certain material facts
concerning sales of gas from the subject leases to the utility division.

     A lawsuit was filed on February 24, 1987, in the 112th Judicial District of
Sutton County, Texas, against subsidiaries and affiliates of ENSERCH, as well as
its utility division.  The plaintiffs have claimed that defendants failed to
make certain production and minimum purchase payments under a gas-purchase
contract.  In this connection, the plaintiffs have alleged a conspiracy to
violate purchase obligations, improper accounting of amounts due, fraud,
misrepresentation, duress, failure to properly market gas and failure to act in
good faith.  In this case, plaintiffs seek actual damages in excess of $5
million and punitive damages in an amount equal to 0.5% of the consolidated
gross revenues of ENSERCH for the years 1982 through 1986 (approximately $85
million), interest, costs and attorneys' fees.

     On December 26, 1989, a lawsuit was filed against EEI and EPO in the 130th
Judicial District Court of Matagorda County, Texas.  The plaintiff claims that
the defendants breached an alleged contract to sell a working interest and net
revenue interest in two leases located in Matagorda County.  Trial of the case
resulted in a jury verdict in favor of the plaintiff.  Judgment was entered by
the trial court on October 8, 1992, ordering EEI and EPO to convey the leases to
the plaintiff and to pay damages of $3.1 million, which includes principal,
prejudgment interest, attorneys' fees and costs.  This judgment was appealed to
the Corpus

                                      F-20
<PAGE>
 
Christi Court of Appeals on September 2, 1992.  Counsel has advised that there
is a reasonable basis to believe that the decision of the trial court will be
reversed.

     On October 25, 1991, a lawsuit was filed against EEI, EPO and ENSERCH in
the 111th District Court of Webb County Texas.  Other parties have intervened.
The plaintiffs and intervenors claim that the defendants' failure to reassign
part of a gas and oil lease covering approximately 33,000 net mineral acres in
breach of defendants' contractual reassignment obligations entitles them to
recover the fair market value of the lost leasehold estate and lost overriding
royalty interests.  Plaintiffs and intervenors claim actual damages of
approximately $3.1 million for the lost leasehold estate, and approximately $2.2
million for the lost overriding royalty interests.  They also seek pre-judgment
interest, attorney's fees and costs.

     Management believes that the named defendants have meritorious defenses to
the claims made in these and other actions.  In the opinion of management, EP
will incur no liability from these and all other pending claims and suits that
would be considered material for financial reporting purposes.

6.   SUPPLEMENTAL FINANCIAL INFORMATION

     Quarterly Results (Unaudited) - The results of operations by quarters are

  At December 31, 1993, approximately 43% of excluded costs relates to offshore
activities in the Gulf of Mexico and the remainder relates to domestic onshore
exploration activities.  The anticipated timing of the inclusion of these costs
in the amortization computation will be determined by the rate at which
exploratory and development activities continue, which is expected to be
accomplished within ten years.

  Gas and Oil Reserves (Unaudited) - The following table of estimated proved and
proved developed reserves of gas and oil has been prepared utilizing estimates
of year end reserve quantities provided by DeGolyer and MacNaughton, independent
petroleum consultants. Reserve

estimates are inherently imprecise and estimates of new discoveries are more
imprecise than those of producing gas and oil properties. Accordingly, the
reserve estimates are expected to change as additional performance data becomes
available. Oil reserves (which include condensate and natural gas liquids
attributable to leasehold interests) are stated in thousands of barrels (MBbl).
Gas reserves are stated in million cubic feet (MMcf). All reserves are located
in the United States.

     Standardized Measure of Discounted Future Net Cash Flows Relating to Proved
Gas and Oil Reserve Quantities (Unaudited) - has been prepared by EP using
estimated future production rates and associated production and development
costs.  Continuation of economic conditions existing at the balance sheet date
was assumed.  Accordingly, estimated future net cash flows were computed by:
applying prices in contracts in effect in December to estimated future
production of proved gas and oil reserves; estimating future expenditures to
develop proved reserves; and estimating costs to produce the proved reserves
based on average costs for the year.  Average prices used in the computations
were:

</TABLE>

Because of the imprecise nature of reserve estimates and the unpredictable
nature of other variables used, the standardized measure should be interpreted
as indicative of the order of magnitude only and not as precise amounts.

Dallas, TX  75201

Gentlemen:

     We understand that Enserch Exploration, Inc. ("EEI"), as Managing General
Partner of Enserch Exploration Partners, Ltd. ("EP" or the "Partnership") is
proposing a plan of reorganization (the "Reorganization"), pursuant to which (i)
New Enserch Exploration, Inc., a newly organized Texas corporation that will
change its name to Enserch Exploration, Inc. ("Newco"), will acquire all of the
outstanding partnership interests of EP Operating Limited Partnership ("EPO"),
which is the limited partnership in which EP has a 99% limited partner interest
and which holds EP's gas and oil properties, in exchange for shares of common
stock of Newco, par value $1.00 per share ("Common Stock"); (ii) EPO will then
be merged into Newco and (iii) EP then will be liquidated, with all partners
receiving shares of Common Stock, and with ENSERCH Corporation ("EC") and its
corporate subsidiaries and affiliated partnerships (collectively with EC, the
"EC Companies") also receiving certain leases and the concomitant obligations of
EP and retaining approximately $395 million of EP's liabilities upon the
liquidation of EP.  Upon the liquidation of EP and the distribution of Common
Stock, holders of outstanding limited partnership interests ("Units") other than
the EC Companies (the "Public Unitholders") will receive one share of Common
Stock for each Unit then held, which shares of Common Stock will be traded on
the New York Stock Exchange.

     You have asked us to render our opinion as to the fairness of the
Reorganization to the Public Unitholders from a financial point of view.

In arriving at our opinion, we have, among other things:

     (1)  Reviewed a draft of the Registration Statement to be filed by Newco
          with the Securities and Exchange Commission;

     (2)  Reviewed the Partnership's Annual Reports on Form 10-K  since
          inception through December 31, 1993 and Quarterly Reports on Form 10-Q
          for the quarters ended March 31, 1994, June 30, 1994 and September 30,
          1994;

     (3)  Reviewed and discussed the Partnership's Reserve Report (dated January
          1,

                                                                          Page 2
 
          1994) with representatives of DeGolyer and MacNaughton, the
          Partnership's independent petroleum engineering firm that prepared
          such report (the "Reserve Report");

     (4)  Reviewed historic financial and operating results of the Partnership
          (since its original public offering on April 23, 1985) and discussed
          with senior management of EEI and EC their business plans for Newco,
          including (i) their intention to increase the percentage  ownership of
          Newco held by the public, (ii) their intention to reinvest Newco's
          cash flow in its business and (iii) their intention to maintain a
          significant ownership interest in Newco;

     (5)  Reviewed and discussed with management financial and operating
          projections, including certain reserve economic forecasts, provided by
          EEI regarding the business plans and prospects for Newco, including
          its capital expenditure program and dividend policy;

     (6)  Reviewed certain financial ratios, derived from financial and
          operating data provided by EEI management, of (i) the Partnership and
          (ii) Newco on a pro forma basis giving effect to the Reorganization;

     (7)  Reviewed the historical market prices, distributions and trading
          volumes of the EP units;

     (8)  Reviewed and contrasted the distribution rights of the Public
          Unitholders to those of certain other publicly traded partnerships
          offered subsequent to EP's original offering;

     (9)  Analyzed the current marketplace receptivity for natural resource
          publicly traded partnerships;

     (10) Analyzed the financial and operating results of certain oil and gas
          exploration and production corporations which we deemed to be
          reasonably similar to the Partnership, and studied the marketplace for
          the securities, including  common stock, of such prospective issuers;
          and

     (11) Reviewed such other financial studies, analyses and investigations as
          we deemed appropriate.

     In our review, and in arriving at our opinion, we have relied on the
accuracy and completeness of all information supplied or otherwise made
available to us by EC and EEI, and we have not independently verified such
information or undertaken an independent appraisal of the assets of the
Partnership.  We have also relied upon the management of EEI as to the
reasonableness of and the ability to achieve the financial forecasts (which
include the reserve

                                                                          Page 3

economic forecasts) of Newco and EP as provided to us, and we have assumed that
such forecasts have been reasonably prepared on a basis reflecting the best
currently available estimates and judgments of such management as to the future
operating performance of Newco and EP.  We have assumed that the Reserve Report
has been reasonably prepared and reflects the best currently available estimates
and judgments of DeGolyer and MacNaughton as to the reserves and future
production volumes of EP.  We have also relied on the determination of EEI and
its legal counsel as to the federal income tax consequences of the
Reorganization to the Public Unitholders, which is described in the
Prospectus/Information Statement.

     On the basis of, and subject to the foregoing, we are of the opinion that
the proposed Reorganization, taken as a whole, is fair to the Public Unitholders
from a financial point of view.

                                                       Sincerely,

General Partner"), a Delaware corporation formerly named Enserch Exploration,
Inc., ENSERCH CORPORATION (the "Special General Partner"), a Texas corporation,
ENSERCH EXPLORATION PARTNERS, LTD. (the "Limited Partner"), a Texas limited
partnership.

                                   RECITALS:

       A.   EP Operating Limited Partnership, formerly EP Operating Company,
Ltd. and EP Operating Company (the "Partnership"), was organized as a Texas
limited partnership pursuant to the provisions of the Texas Uniform Limited
Partnership Act (Article 6132a, Vernon's Texas Statutes) (the "Uniform Act")
upon the filing with the Secretary of State of the State of Texas on March 7,
1985 of a Certificate of Limited Partnership for the Partnership and pursuant to
an original Agreement of Limited Partnership.  The original Agreement of Limited
Partnership was amended and restated as of April 30, 1985 and was thereafter
amended by Amendment No. 1 dated as of September 1, 1992, Amendment No. 2 dated
as of  October 23, 1992, Amendment No. 3 dated as of July 9, 1993 and Amendment
No. 4 dated as of December 8, 1994 (as so amended, the "Agreement").

       B.   The Managing General Partner has determined that it is in the best
interests of the Partnership and the Partners that the Agreement be further
amended as set forth herein and has proposed this Amendment to the Agreement.
The Special General Partner and the Limited Partner have consented to this
Amendment.

       NOW, THEREFORE, Managing General Partner, Special General Partner and
Limited Partner hereby amend the Agreement as set forth below pursuant to
Section 14.1(a) of the Agreement:

       1.   Article X of the Agreement is amended by adding the following
Section 10.4 thereto:

            "10.4  Contributions to Newco.  Any other provision of 
       this Agreement notwithstanding, the Managing General Partner,
       Special

                                       1
<PAGE>
 
       General Partner, and Limited Partner may assign, contribute
       and transfer their Partnership Interests to New Enserch
       Exploration, Inc., a Texas corporation organized in 1994 as
       New Enserch Exploration, Inc. ("Newco") whose name will be
       changed to Enserch Exploration, Inc. in the merger with the
       Partnership authorized below, in exchange for shares of Newco
       common stock pursuant to a Contribution of Partnership
       Interests Agreement substantially in the form of APPENDIX 
       `EPO-1' hereto, the execution and delivery of which on behalf
       of the Partnership are hereby authorized. Newco may assign,
       contribute and transfer a portion of such Partnership
       Interests to a wholly owned subsidiary of Newco and the
       Partnership may merge with Newco and that subsidiary pursuant
       to a plan of merger adopted for the Partnership by Newco as
       successor Managing General Partner of the Partnership, with
       Newco being the surviving entity of such merger. The
       permission to transfer Partnership Interests contained in this
       Section 10.4 does not otherwise affect or amend the
       restrictions on transfer contained in Section 10.1(b), which
       is hereby ratified."

       2.   Article XIII of the Agreement is amended to amend Section 13.4 in
its entirety to read as follows:

            "13.4 Distribution in Kind. Notwithstanding the provisions
       of Section 13.3 which require the liquidation of the assets of
       the Partnership, but subject to the order of priorities set
       forth therein, if on dissolution of the Partnership the
       Liquidator determines that an immediate sale of part or all of
       the Partnership's assets would be impractical or would cause
       undue loss to the Partners, the Liquidator may, in its
       absolute discretion, defer for a reasonable time the
       liquidation of any assets except those necessary to satisfy
       liabilities of the Partnership (other than those to Partners)
       and may, in its absolute discretion, distribute to the
       Partners, in lieu of cash, in accordance with the provisions
       of Sections 13.3(c) and 13.3(d), such Partnership assets as
       the Liquidator deems appropriate, including non pro rata
       distributions. Any distributions in kind shall be subject to
       such conditions relating to the disposition and management
       thereof as the Liquidator deems reasonable and equitable and
       to any joint operating agreements or other agreements
       governing the operation of such properties at such time. The
       Liquidator shall determine the fair market value of any
       property distributed in kind using such reasonable method of
       valuation as it may adopt."

       3.   Except as specifically amended hereby, the Agreement remains in full
force and effect as written.

       IN WITNESS HEREOF, Managing General Partner, Special General Partner and

                                       2

       NOW, THEREFORE, for valuable consideration, the parties agree as follows:

       1.   ASSIGNMENTS OF PARTNERSHIP INTERESTS.  The parties hereby make the
following contributions and assignments of Partnership Interests in EPO.  The
contributions and assignments are made serially, in the order set forth in this

Interests assigned and contributed by this Contribution Agreement not all be
owned by Newco at any one time but that at all times there be at least two
persons owning such Partnership Interests.

       Stock by Newco to EP, EP by these presents does CONTRIBUTE, ASSIGN,
       TRANSFER AND CONVEY unto Newco a one percent (1%) Partnership Interest as

       does CONTRIBUTE, ASSIGN, TRANSFER AND CONVEY unto Newsub a one percent
       (1%) Partnership Interest as Limited Partner in EPO.

       of Newco Common Stock by Newco to EP, EEI and EC, EP, EEI and EC by these
       presents do CONTRIBUTE, ASSIGN, TRANSFER AND CONVEY unto Newco all of (i)
       EP's remaining Partnership Interest as Limited Partner in EPO and (ii)
       EEI's Partnership Interest as Managing General Partner of EPO and EC's
       Partnership Interest as Special General Partner of EPO. The aggregate of
       103,535,430 shares of Newco Common Stock so issued shall be apportioned
       between EP, EC and EEI so that the entire 104,581,242 shares of Newco
       Common Stock issued in connection with this Contribution Agreement are
       apportioned among EP, EC and EEI in accordance with the balances in their
       respective capital accounts in EPO at such time.

       2.   ACCEPTANCE OF ASSIGNMENTS.  Each assignee of a Partnership Interest
hereby accepts the contribution and assignment to it of such Partnership
Interest.

       3.   ISSUANCE OF SHARES.  Newco hereby agrees to issue shares of Newco
Common Stock in consideration of the assignments and contributions described in
Paragraph 1, in the amounts, at the times and with respect to the assignments
and contributions described in Paragraph 1.  Newco shall promptly deliver
certificates representing such shares to the persons entitled thereto.

       4.   WARRANTIES AND REPRESENTATIONS OF ASSIGNORS.  EP, EEI and EC each
warrants and represents to Newco that it has granted no other assignments or
security interests in its respective Partnership Interests contributed,
assigned, transferred and conveyed by this

                                       2
<PAGE>
 
Contribution Agreement, that it has the full right, power and authority to
execute this Contribution Agreement, that all consents required for this
Contribution Agreement have been obtained and that, immediately prior to its
assignment thereof, it was the owner of the Partnership Interests assigned by
it.

       5.   WARRANTIES AND REPRESENTATIONS OF ASSIGNEES.  Newco and Newsub each
warrants, represents and certifies to EP, EEP, EC and Newco and to EPO that it
is an Eligible Citizen.

       6.   ADMISSION OF NEWCO AND NEWSUB TO THE PARTNERSHIP.  Newco is hereby
admitted to EPO as Managing General Partner, Special General Partner and Limited
Partner, each to the extent of the Partnership Interests assigned to Newco in
paragraph 1 in full substitution of EEI, EC and EP as to such interests.  Newsub
is hereby admitted to EPO as the Limited Partner.  From and after this
Assignment, EEI is no longer the Managing General Partner of EPO, EC is no
longer the Special General Partner of EPO and EP is no longer the Limited
Partner of EPO, and each is deemed to have withdrawn from  EPO as a result of
this Assignment and the admission of Newco and Newsub in their respective places
as Partners.

       7.   MERGER OF EPO, NEWSUB AND NEWCO. Promptly after the contributions to
Newco and Newsub described in paragraph 1 and the admission of Newco and Newsub
to the Partnership as described in paragraph 6, EPO and Newsub shall merge with
Newco pursuant to a plan of merger adopted for the Partnership by Newco, with
Newco being the surviving entity of such merger (the "Merger") and with the name
of Newco being changed to Enserch Exploration, Inc. in the Merger. In the Merger
the 1,000 shares of Newco Common Stock originally issued to EPO in the
organization of Newco shall be cancelled.

       8.   FURTHER ASSURANCES.  Each party shall execute such further
documentation that may reasonably be required in order to effect the
contributions, assignments and issuances of shares of stock described herein.

       EXECUTED on the date set forth above.

     Partnership properties) shall, immediately prior to any such distribution,
     be adjusted (consistent with the provisions hereof and Section 704 of the
     Code) upwards or downwards to reflect any Unrealized Gain or Unrealized

     or Unrealized Loss had been recognized upon an actual sale of such
     properties, immediately prior to such distribution, and was allocated to
     the Partners, at such time, pursuant to Section 5.1). In determining such
     Unrealized Gain or Unrealized Loss attributable to the properties, the fair
     market value of Partnership properties shall be determined by the Managing

     Liquidator may, in its absolute discretion, defer for a reasonable time the

     the Partnership (other than those to Partners) and may, in its absolute
     discretion, distribute to the Partners, in lieu of cash, in accordance with

     conditions relating to the disposition and management thereof as the
     Liquidator deems reasonable and equitable and to any joint operating
     agreements or other agreements governing the operation of such properties
     at such time. The Liquidator shall determine the fair market value of any
     property distributed in kind using such reasonable method of valuation as
     it may adopt."

     8.   Article XIV of the Agreement is further amended by adding the
following Section 14.7.

     Liquidation attached hereto as APPENDIX `EP-1' and incorporated herein by

     of effecting the Plan of Liquidation, and, as such, the Managing General
     Partner has the authority, and is hereby directed, to carry out the Plan of
     Liquidation and to take all actions required thereby or that the Managing
     General Partner believes to be in the best interests of the Partnership and
     in accordance with the Plan of Liquidation. To the extent the Plan of
     Liquidation requires or permits actions to be taken that are not otherwise
     authorized by Article XIV of this Agreement, the Plan of Liquidation
     controls and the Managing General Partner is authorized to take such
     actions. Without limiting the generality of the foregoing grant of
     authority, the Managing General Partner is authorized to make distributions
     of Partnership assets in kind to the Partners in accordance with the Plan
     of Reorganization even though the allocation may not be proportionate to
     the interests of the Partners."

     9.   Article XVI of the Agreement is amended to amend Section 16.1(b) to
add the following:

     "A Majority Interest has consented to certain amendments to the Operating
     Partnership Agreement and to the contribution and assignment of the
     partnership interests of EEI, EC and the Partnership in the Operating
     Partnership to Newco in exchange for Newco Common Stock, and the subsequent
     merger of the Operating Partnership and a subsidiary of Newco with Newco,
     in which Newco will be the surviving entity of such merger and the name of
     Newco will be changed to Enserch Exploration, Inc."

     10.  Except as specifically amended hereby, the Agreement remains in full
force and effect as written.

     IN WITNESS HEREOF, the General Partners have caused this Amendment to be
executed by their respective officers thereunto duly authorized on and as of the
dates first above written.

               EEI, subject to the Lease obligations with respect thereto.

<PAGE>
 
          (3)  The Managing General Partner shall distribute all of the
               remaining Newco Common Stock not distributed or distributable
               pursuant to (1) above then held by or for the account of the
               Partnership to EEI and EPPL in relation to their respective
               Capital Accounts, adjusted for the liabilities assumed by them in
               Paragraphs 7 and 8a(2) and the Lease Rights distributed to EEI in
               Paragraph 8a(2).

     b.   Any assets remaining in the Partnership after the distribution of
          Newco Common Stock referred to in a. above shall be contributed to the
          capital of Newco by the Managing General Partner after the payment of
          the obligations of the Partnership as provided in Paragraph 7.

     c.   The transfer books of the Partnership will be permanently closed at
          the close of business on the Liquidation Record Date. Units will not
          be assignable or transferable on the books of the Partnership after
          the Liquidation Record Date except by will, intestate succession or
          operation of law.

     d.   The Newco Common Stock to be distributed to Public Unitholders will be
          delivered to the Depositary to hold for delivery to each Public
          Unitholder entitled thereto upon the surrender to the Depositary by
          such Person of (i) Depositary Receipts or (ii) certificates
          representing the Units, registered in the name of such Person as of
          the close of business on the Liquidation Record Date. Any Newco Common
          Stock which Public Unitholders have the right to receive, but which
          have not been distributed to Public Unitholders because Depositary
          Receipts or Certificates representing such Units have not been
          surrendered to the Depositary, will be held by the Depositary until
          Depositary Receipts or Certificates representing such Units have been
          surrendered to the Depositary or until the Depositary has received
          evidence satisfactory to it, in the Depositary's sole discretion, or
          the Depositary has received other security or indemnity as it may
          require, in the Depositary's sole discretion, at which time the
          Depositary shall deliver to such Persons the Newco Common Stock to
          which the Persons are entitled. The Newco Common Stock Affiliate
          Holders have the right to receive will be delivered upon the surrender
          to the Managing General Partner of certificates representing the Units

of the Company, now or hereafter to be authorized, or any notes, debentures,
bonds or other securities convertible into or carrying options or warrants to
purchase shares of any class or series, now or hereafter to be authorized,
whether or not the issuance of any such shares, or such notes, debentures, bonds
or other securities, would adversely affect the dividend or voting rights of
such shareholders, other than such rights, if any, as the Board of Directors in
its discretion may fix; and the Board of Directors may issue shares of any class
or series of the Company, or any notes, debentures, bonds or other securities

Stock to the extent set forth in the resolution adopted by the Board of
Directors establishing the series.

     (E)   Other Provisions Applicable to Capital Stock:

     (a)   Each outstanding share of Common Stock shall be entitled to one vote
           on each matter submitted to a vote at a meeting of shareholders,

           resolutions adopted by the Board of Directors establishing any series
           of Preferred Stock.

     (b)   At each election for directors, every shareholder entitled to vote at
           such election shall have the right to vote the number of shares owned
           by him for as many persons as there are directors to be elected and
           for whose election he has a right to vote; provided that cumulative
           voting in the election for directors is prohibited.

           remaining assets of the Company available for distribution to its
           shareholders.

     (d)   Any action required by the TBCA to be taken at any annual or special
           meeting of shareholders, or any action which may be taken at any
           annual or special meeting of shareholders, may be taken without a
           meeting, without prior notice, and without a vote, if a consent or
           consents in writing, setting forth the action so taken, shall be
           signed by the holder or holders or shares having not less than the
           minimum number of votes that would be necessary to take such action
           at a meeting at which the holders of all shares entitled to vote on

           the exclusion of Preferred Stock out of any assets of the Company
           available therefor.

ENSERCH Corporation ("EC"), or any subsidiary or other corporation, partnership,
limited liability company or other entity in which EC is directly or indirectly
interested (collectively with EC, an "EC Person"), shall not be invalid because

     the EC Person in connection with the borrowing of funds obtained by the EC

     guaranties) by unrelated lenders on comparable loans.

     (D)  Common Personnel.  Officers, directors, employees, attorneys and
agents of the Company may also serve as directors, officers, employees,
attorneys  or agents of an EC Person, provided that the Company and the EC

based on such factors as net capital employed, the number of employees or the
percentage of time spent on projects or services.

     (G)  Purchase or Sale of Shares.  An EC Person may purchase or otherwise
acquire and sell or otherwise dispose of shares or other securities of the

     Item 20.  Indemnification of Directors and Officers.

          Newco's Articles of Incorporation provide that, to the fullest extent
     permitted by Texas law, directors of Newco will not be liable to Newco or
     its shareholders for monetary damages for any act or omission occurring in
     their capacity as a director.  Texas law does not currently authorize the
     elimination or limitation of the liability of a director to the extent the
     director is found liable for (i) any breach of the director's duty of
     loyalty to Newco or its shareholders, (ii) acts or omissions not in good
     faith that constitute a breach of duty of the director of Newco or which
     involve intentional misconduct or a knowing violation of law, (iii)
     transactions from which the director received an improper benefit, whether
     or not the benefit resulted from an action taken within the scope of the
     director's office or (iv) acts or omissions for which the liability of a
     director is expressly provided by law.

          Newco's Articles of Incorporation and its Bylaws grant mandatory
     indemnification to directors and officers of Newco to the fullest extent
     authorized under the Texas Business Corporation Act.  In general, a Texas
     corporation may indemnify a director or officer who was, is or is
     threatened to be made a named defendant or respondent in a proceeding by
     virtue of his position in the corporation if he acted in good faith and in
     a manner he reasonably believed to be in or not opposed to the best
     interests of the corporation, and, in the case of criminal proceedings, had
     no reasonable cause to believe his conduct was unlawful.  A Texas
     corporation may indemnify a director or officer in an action brought by or
     in the right of the corporation only if such director or officer was not
     found liable to the corporation, unless or only to the extent that a court
     finds him to be fairly and reasonably entitled to indemnity for such
     expenses as the court deems proper.

          Insofar as indemnification for liabilities arising under the
     Securities Act of 1933, as amended (the "Securities Act"), may be permitted
     to directors, officers or persons controlling Newco pursuant to the
     foregoing provisions, Newco has been advised that in the opinion of the
     Commission such indemnification is against public policy as expressed in
     the Securities Act and is therefore unenforceable.

     Item 22.  Undertakings.

          (a) The undersigned Registrant hereby undertakes:

               (1)  To file, during any period in which offers or sales are
          being made, a post-effective amendment to this registration statement:

                    (i)    To include any prospectus required by section
               10(a)(3) of the Securities Act;

                    (ii)   To reflect in the prospectus any facts or events
               arising after the effective date of the registration statement
               (or the most recent post-effective amendment thereof) which,
               individually or in the aggregate, represent a fundamental change
               in the information set forth in the registration statement;

                    (iii)  To include any material information with respect to
               the plan of distribution not previously disclosed in the
               registration statement or any material change to such information
               in the registration statement;

               Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do
          not apply if the information required to be included in a post-
          effective amendment by those paragraphs is contained in periodic
          reports filed by the Registrant pursuant to Section 13 or Section
          15(d) of the Exchange Act that are incorporated by reference in this
          registration statement.

               (2) That, for the purpose of determining any liability under the
          Securities Act, each such post-effective amendment shall be deemed to
          be a new registration statement relating to the securities offered
          therein, and the offering of such securities at that time shall be
          deemed to be the initial bona fide offering thereof.

               (3) To remove from registration by means of a post-effective
          amendment any of the securities being registered which remain unsold
          at the termination of the offering.

          (b)(1)  The undersigned Registrant hereby undertakes as follows: that
     prior to any public reoffering of the securities registered hereunder
     through use of a prospectus which is a part of this registration statement,
     by any person or party who is deemed to be an underwriter within the
     meaning of Rule 145(c), the issuer undertakes that such reoffering
     prospectus will contain the information called for by the applicable
     registration form with respect to reofferings by persons who may be deemed
     underwriters, in addition to the information called for by the other Items
     of the applicable form.

          (2)  The Registrant undertakes that every prospectus (i) that is filed
     pursuant to paragraph (1) immediately preceding, or (ii) that purports to
     meet the requirements of section 10(a)(3) of the Securities Act and is used
     in connection with an offering of securities subject to Rule 415,

                                      II-3
<PAGE>
 
     will be filed as part of an amendment to the Registration Statement and
     will not be used until such amendment is effective, and that, for purposes
     of determining any liability under the Securities Act, each such post-
     effective amendment shall be deemed to be a new registration statement
     relating to the securities offered therein, and the offering of such
     securities at that time shall be deemed to be the initial bona fide
     offering thereof.

          (c)  Insofar as indemnification for liabilities arising under the
     Securities Act may be permitted to directors, officers and controlling
     persons of the Registrant pursuant to the foregoing provisions, or
     otherwise, the Registrant has been advised that in the opinion of the
     Securities and Exchange Commission such indemnification is against public
     policy as expressed in the Securities Act and is, therefore, unenforceable.
     In the event that a claim for indemnification against such liabilities
     (other than the payment by the Registrant of expenses incurred or paid by a
     director, officer or controlling person of the Registrant in the successful
     defense of any action, suit or proceeding) is asserted by such director,
     officer or controlling person in connection with the securities being
     registered, the Registrant will, unless in the opinion of its counsel the
     matter has been settled by controlling precedent, submit to a court of
     appropriate jurisdiction the question whether such indemnification by it is
     against public policy as expressed in the Securities Act and will be
     governed by the final adjudication of such issue.

          (d)  The undersigned Registrant hereby undertakes to respond to
     requests for information that is incorporated by reference into the
     Prospectus pursuant to Items 4, 10(b), 11 or 13 of this Form, within one
     business day of receipt of such request, and to send the incorporated
     documents by first class mail or other equally prompt means.  This includes
     information contained in documents filed subsequent to the effective date
     of the Registration Statement through the date of responding to the
     request.

          (e)  The undersigned Registrant hereby undertakes to supply by means
     of a post-effective amendment all information concerning a transaction, and
     the company being acquired involved therein, that was not the subject of
     and included in the Registration Statement when it became effective.

operate upon the designations, preferences, limitations and relative rights of
the shares of any series shall be set forth in the resolution or resolutions
establishing the series.

dividend or voting rights of such shareholders, other than such rights, if any,
as the Board of Directors in its discretion may fix; and the Board of Directors
may issue shares of any class or series of the Company, or any notes,
debentures, bonds or other securities convertible into or carrying options or
warrants to purchase shares of any class or series, without offering any such
shares of any class or series, either in whole or in part, to the existing
shareholders of any class or series.

     (D)  Subordination of Common Stock:  The Common Stock shall be subject and
subordinate to the rights, privileges and preferences of any series of Preferred
Stock to the extent set forth in the resolution adopted by the Board of
Directors establishing the series.

          pro rata all of the remaining assets of the Company available for
          distribution to its shareholders.

     (d)  Any action required by the TBCA to be taken at any annual or special
          meeting of shareholders, or any action which may be taken at any
          annual or special meeting of shareholders, may be taken without a
          meeting, without prior notice, and without a vote, if a consent or
          consents in writing, setting forth the action so taken, shall be
          signed by the holder or holders or shares having not less than the
          minimum number of votes that would be necessary to take such action at
          a meeting at which the holders of all shares entitled to vote on the
          action were present and voted.

          in the resolutions adopted by the Board of Directors establishing any
          series of Preferred Stock, dividends may be paid upon Common Stock to

ENSERCH Corporation ("EC"), or any subsidiary or other corporation, partnership,
limited liability company or other entity in which EC is directly or indirectly

     the EC Person's actual average interest cost (including points or other
     financing charges or fees, if any), or (ii) the rate (including points or

     guaranties) by unrelated lenders on comparable loans.

     (D)  Common Personnel.  Officers, directors, employees, attorneys and
agents of the Company may also serve as directors, officers, employees,

complete list of the shareholders entitled to vote at such meeting or any
adjournment thereof, arranged in alphabetical order, with the address of and the
number of shares held by each, which list, for a period of ten (10) days prior
to such meeting, shall be kept on file at the registered office of the
corporation and shall be subject to inspection by any shareholder at any time
during usual business hours.  Such list shall also be produced and kept open at
the time and place of the meeting and shall be subject to the inspection of any
shareholder during the whole time of the meeting.  The original stock transfer
books shall be prima-facie evidence as to who are the shareholders entitled to
examine such list or transfer books or to vote at any meeting of shareholders.

          Section 6.  The holders of a majority of the shares issued and
outstanding and entitled to vote thereat, present in person or represented by
written proxy, shall constitute a quorum at all meetings of the shareholders for
the transaction of business.  If, however, such quorum shall not be present or
represented at any meeting of the shareholders, the shareholders entitled to
vote thereat, present in person or represented by proxy, shall have power to
adjourn the meeting from time to time, without notice other than announcement at
the meeting, until a quorum shall be present or represented.  At such adjourned
meeting at which a quorum shall be present or represented any business may be
transacted which might have been transacted at the meeting as originally
notified.

          Section 7.  Each outstanding share, of any class, shall be entitled to
as many votes per share as the Articles of Incorporation shall provide, on each
matter submitted to a vote at a meeting of shareholders, except to the extent
that the voting rights of the shares of any class or classes are limited or
denied by the Articles of Incorporation or these Bylaws.  The vote for the

                                       3

election of Directors and, upon demand by any shareholder, the vote upon any
question before the meeting shall be by ballot.  Cumulative voting is expressly
prohibited.

          Section 8.  At any meeting of the shareholders, every shareholder
having the right to vote shall be entitled to vote in person or by proxy
executed in writing by such shareholder or by his duly authorized attorney-in-
fact.  No proxy shall be valid after eleven (11) months from the date of its
execution unless otherwise provided in the proxy.  All proxies shall be
revocable unless expressly provided therein to be irrevocable and are coupled
with an interest and shall be filed with the Corporate Secretary of the
corporation prior to or at the time of the meeting at which they are to be
voted.

          Section 9.  When a quorum is present at any meeting, matters brought
before the meeting shall be determined by the shareholders in the following
manner:  (a) with respect to any matter, other than the election of Directors or
a matter for which the affirmative vote of a specified portion of the shares
entitled to vote is required by the statutes, the act of the shareholders shall
be the affirmative vote of the holders of a majority of the shares entitled to
vote on, and voted for or against, that matter at a meeting of shareholders at
which a quorum is present and (b) with respect to the election of Directors, the
act of the shareholders electing the Directors shall be a plurality of the votes
cast by the holders of shares entitled to vote in the election of Directors at a
meeting of shareholders at which a quorum is present, unless the question is one
upon which, by express provision of the statutes or of the Articles of
Incorporation or of these Bylaws, a different vote is required, in which case
such express provision shall govern and control the decision of such question.
The shareholders present at a duly organized meeting may

                                       4
<PAGE>
 
continue to transact business until adjournment, notwithstanding the withdrawal
of enough shareholders to leave less than a quorum.

          Section 10.  The Chairman shall preside at all meetings of the
shareholders.  In his absence, the President or an officer of the corporation
designated by the Board of Directors shall preside and perform the duties of the
Chairman at such meeting.  He shall appoint two inspectors of voting to serve at
each such meeting.  Before acting at any meeting, the inspectors shall be sworn
faithfully to execute their duties with strict impartiality and according to the
best of their ability.  The inspectors shall determine the number of shares
outstanding, the voting power of each, the shares represented at the meeting,
the existence of a quorum, the qualification of the voters, the authenticity,
validity and effect of proxies, receive votes and ballots, hear and determine
all challenges and questions in any way arising in connection with the vote,
count and tabulate all votes and determine and announce the result of the
voting.

          Section 11.   At an annual meeting of the shareholders, only such
business shall be conducted as shall have been properly brought before the
meeting.  To be properly brought before an annual meeting, business must be
specified in the notice of meeting (or any supplement thereto) given by or at
the direction of the Board, otherwise properly brought before the meeting by or
at the direction of the Board, or otherwise properly brought before the meeting
by a shareholder.  In addition to any other applicable requirements, for
business to be properly brought before an annual meeting by a shareholder, the
shareholder must have given timely notice thereof in writing to the Corporate
Secretary.  To be timely, a shareholder's notice must be delivered to or mailed
and received at the principal executive offices of the corporation, not less
than fifty (50) days nor more than seventy-five (75) days prior to the meeting;
provided,

                                       5
<PAGE>
 
however, that in the event that less than sixty-five (65) days' notice or prior
public disclosure of the date of the meeting is given or made to shareholders,
notice by the shareholder to be timely must be so received not later than the
close of business on the 15th day following the day on which such notice of the
date of the annual meeting was mailed or such public disclosure was made.  A
shareholder's notice to the Corporate Secretary shall set forth as to each
matter the shareholder proposes to bring before the annual meeting (i) a brief
description of the business desired to be brought before the annual meeting and
the reasons for conducting such business at the annual meeting, (ii) the name
and record address of the shareholder proposing such business, (iii) the class
and number of shares of the corporation which are beneficially owned by the
shareholder, and (iv) any material interest of the shareholder in such business.

          Notwithstanding anything in the Bylaws to the contrary, no business
shall be conducted at the annual meeting except in accordance with the
procedures set forth in this Section 11; provided, however, that nothing in this
                                         --------  -------                      
Section 11 shall be deemed to preclude discussion by any shareholder of any
business properly brought before the annual meeting in accordance with said
procedure.

          The Chairman of an annual meeting shall, if the facts warrant,
determine and declare to the meeting that business was not properly brought
before the meeting in accordance with the provisions of this Section 11, and if
he should so determine, he shall so declare to the meeting and any such business
not properly brought before the meeting shall not be transacted.

          Section 12.  Only persons who are nominated in accordance with the
following procedures shall be eligible for election as Directors.  Nominations
of persons for election to the Board of the corporation may be made at a meeting
of shareholders by or at the direction of the

                                       6
<PAGE>
 
Board of Directors by any nominating committee or person appointed by the Board
or by any shareholder of the corporation entitled to vote for the election of
Directors at the meeting who complies with the notice procedures set forth in
this Section 12.  Such nominations, other than those made by or at the direction
of the Board, shall be made pursuant to timely notice in writing to the
Corporate Secretary.  To be timely, a shareholder's notice shall be delivered to
or mailed and received at the principal executive offices of the corporation not
less than fifty (50) days nor more than seventy-five (75) days prior to the
meeting; provided, however, that in the event that less than sixty-five (65)
         --------  -------                                                  
days' notice or prior public disclosure of the date of the meeting is given or
made to shareholders, notice by the shareholder to be timely must be so received
not later than the close of business on the 15th day following the date on which
such notice of the date of the meeting was mailed or such public disclosure was
made.  Such shareholder's notice to the Corporate Secretary shall set forth (a)
as to each person whom the shareholder proposes to nominate for election or re-
election as a Director, (i) the name, age, business address and residence
address of the person, (ii) the principal occupation or employment of the
person, (iii) the class and number of shares of capital stock of the corporation
which are beneficially owned by the person, and (iv) any other information
relating to the person that is required to be disclosed in solicitations for
proxies for election of Directors pursuant to Rule 14a under the Securities
Exchange Act of 1934 as amended; and (b) as to the shareholder giving the notice
(i) the name and record address of shareholder and (ii) the class and number of
shares of capital stock of the corporation which are beneficially owned by the
shareholder.  The corporation may require any proposed nominee to furnish such
other information as may reasonably be required by the corporation to determine
the eligibility of such proposed nominee

                                       7
<PAGE>
 
to serve as Director of the corporation.  No person shall be eligible for
election as a Director of the corporation unless nominated in accordance with
the procedures set forth herein.

          The Chairman of the meeting shall, if the facts warrant, determine and
declare to the meeting that a nomination was not made in accordance with the
foregoing procedure, and if he should so determine, he shall so declare to the
meeting and the defective nomination shall be disregarded.

                                  ARTICLE III

                                   DIRECTORS

          Section 1.  The business and affairs of the corporation shall be
managed by its Board of Directors who may exercise all such powers of the
corporation and do all such lawful acts and things as are not by statute or by
the Articles of Incorporation or by these Bylaws directed or required to be
exercised or done by the shareholders.

          Section 2.  The Board of Directors shall consist of not less than two
Directors, none of whom need be shareholders or residents of the State of Texas;
the exact number of Directors to be determined from time to time by resolution
adopted by the Board of Directors.  A person shall be ineligible to be a
Director of the corporation after the date of the annual meeting of shareholders
of the corporation in the year in which such person's seventieth birthday
occurs.  The Directors shall be elected at the annual meeting of the
shareholders, except as provided in Section 4 of this Article III.  Unless he
shall resign or become ineligible, each Director shall hold office until his
successor shall be elected and shall qualify.

          Section 3.  Any Director may resign at any time either by oral tender
of resignation at any meeting of the Board of Directors or by giving written
notice thereof to the Corporate

                                       8
<PAGE>
 
Secretary.  Resignations shall take effect when tendered or at the time
specified in the tender and, unless otherwise specified, the acceptance of a
resignation shall not be necessary to make it effective.

          Section 4.  Any Director may be removed either for or without cause,
at any special meeting of shareholders by the affirmative vote of the holders of
record of a majority of the shares present in person or by proxy at such meeting
and entitled to vote for such removal, if notice of the intention to act upon
such matter shall have been given in the notice calling for such meeting.  Any
vacancy occurring in the Board of Directors may be filled by the affirmative
vote of a majority of the remaining Directors even though such remaining
Directors shall be less than a quorum of the Board of Directors.  A Director
elected to fill a vacancy shall be elected for the unexpired term of his
predecessor in office.  Any directorship to be filled by reason of an increase
in the number of directors may be filled by election at an annual meeting or at
a special meeting of shareholders called for that purpose or may be filled by
the Board of Directors for a term of office continuing until the next election
of one or more Directors by the shareholders; provided that the Board of
Directors may not fill more than two such directorships between any two
successive annual meetings of shareholders.

          Section 5.  The Board of Directors, by resolution adopted by a
majority of the full Board of Directors, may designate from among its members
one or more committees, each of which shall be comprised of one or more of its
members, and may designate one or more of its members as alternate members of
any committee, who may, subject to any limitations imposed by the Board of
Directors, replace absent or disqualified members at any meeting of that
committee.  Any such committee, to the extent provided in such resolutions or in
the Articles

                                       9
<PAGE>
 
of Incorporation or the Bylaws, shall have and may exercise all of the authority
of the Board of Directors, provided that no committee of the Board of Directors
shall have the authority of the Board of Directors in reference to:  (1)
amending the Articles of Incorporation, except that a committee may, to the
extent provided in the resolution designating that committee or in the Articles
of Incorporation or the Bylaws, exercise the authority of the Board of Directors
vested in it in accordance with Article 2.13 of the Texas Business Corporation
Act ("Act"); (2) proposing a reduction of the stated capital of the Corporation
in the manner permitted by Article 4.12 of the Act;  (3) approving a plan of

particular committee, the Articles of Incorporation, or the Bylaws expressly so
provide, no committee of the Board of Directors shall have the authority to
authorize a distribution or to authorize the issuance of shares of the
Corporation.

on twenty-four (24) hours' notice to each Director, or such shorter period of
time as the person calling the meeting deems appropriate in the circumstances,
either personally, or by mail, or by telegram; special meetings shall be called
by the Chairman or, in the event of the inability of the Chairman to act, the

the purpose of, any special meeting need be specified in a notice or waiver of
notice.

          Section 10.  At all meetings of the Board of Directors the presence of
a majority of the Directors shall constitute a quorum for the transaction of

required or permitted to be taken at a meeting of the Board of Directors may be
taken without a meeting if a consent in writing, setting forth the action so
taken, is

                                       11
<PAGE>

Articles of Incorporation or of these Bylaws, notice is required to be given to
any Director or shareholder, and no provision is made as to how such notice
shall be given, it shall not be construed to mean personal notice, but any such
notice may be given in writing, by mail, postage prepaid, addressed to such
Director or shareholder at such address as appears on the books of the
corporation.  Any notice required or permitted to be given by mail shall be
deemed to be given at the time when the same shall be thus deposited in the

such notice.  Attendance of a Director at a meeting shall constitute a waiver of
notice of such meeting, except when a Director attends a meeting for the express
purpose, in writing filed at

          Section 9. SIGNATURES ON SHARE CERTIFICATES, BONDS, DEBENTURES AND
EVIDENCES OF INDEBTEDNESS.  In case any officer who signed, or whose facsimile
signature has been placed on any certificate representing shares of stock, bond,
debenture or evidence of indebtedness of this corporation shall cease to be an
officer of the corporation for any reason before the same has been issued or

          Section 1.  PURPOSE AND EFFECTIVENESS.  The purpose of this Article XV
is to limit ownership and control of shares of any class of capital stock of the
corporation by persons who are not Eligible Citizens in order to permit the
corporation or any of its Subsidiaries to conduct its business as a U.S. Mineral
Lessee.  The Board of Directors is hereby authorized to adopt such resolutions,
and to effect any and all other measures reasonably necessary or desirable
(consistent with applicable law and the provisions of the Articles of
Incorporation) to fulfill the purpose and implement the restrictions of this
Article XV, including without limitation, requiring, as a condition precedent to
the transfer of shares on the records of the corporation, representations and
other proof as to the identity of existing or prospective shareholders and
persons on whose behalf of shares of any class of capital stock of the

          Section 2.  RESTRICTION ON TRANSFERS.  Any transfer, or attempted or
purported transfer, of any shares of any class of capital stock issued by the
corporation or any interest therein or right thereof, which would result in the
ownership or control by one or more non-Eligible Citizens of the shares of any
class of capital stock of the corporation or of any interest or right therein
will, until such condition no longer exists, be void and will be ineffective as
against the corporation and the corporation will not recognize the purported
transferee as a shareholder of the corporation for any purpose other than the
transfer of such shares to a person who is an Eligible Citizen; provided,
however, that such shares may nevertheless be deemed to be shares held or owned
by non-Eligible Citizens for the purposes of this Article XV.

          Section 3.  SUSPENSION OF VOTING, DIVIDEND AND DISTRIBUTION RIGHTS.
No shares of the outstanding capital stock of the corporation or any class
thereof transferred to, or acquired or held by, a non-Eligible Citizen shall be
entitled to receive or accrue any rights with respect to any dividends or other
distributions of assets declared payable or paid to the holders of such capital
stock during such period.  Furthermore, no shares held by or for the benefit of
any non-Eligible Citizen will be entitled to vote with respect to any matter
submitted to stockholders of the corporation so long as such condition exists.

or is threatened to be named, as a party in a judicial or administrative
proceeding that seeks the cancellation or forfeiture of any property, lease,
right or license in which the corporation has an interest or (ii) if, in the
opinion of the Board of Directors, the corporation's ability to hold any
property, lease, right or license would be prohibited or restricted because of
the nationality, citizenship, residence, or other status, of any shareholder of
the corporation (or, in the case of a shareholder which is a corporation,
partnership or association, of any shareholder, owner, partner or member of such
shareholder), the corporation may redeem the shares held by such shareholder at

venturers or other equity participants are Eligible Citizens and that such
association, joint venture or other entity is capable of holding leases or other
interest in federal minerals or lands under the laws of the United States.

          "Quoted Price" means, with respect to any class of capital stock of
the corporation, the last reported sales price regular way or, in case no such
reported sale takes place on such day, the average of the closing bid and asked
prices regular way for such day, in each case on the principal national
securities exchange on which the shares of such class of capital stock are
listed or admitted to trading or, if not listed or admitted to trading, the last
sale price regular way for such shares as published by NASDAQ, or if such last
price is not so published by NASDAQ or if no such sale takes place on such day,

by NASDAQ or in the absence of any of the foregoing, the fair market value as
determined by the Board of Directors.

     Re:  Reorganization of Enserch Exploration Partners, Ltd.

Gentlemen:

     We have acted as counsel for New Enserch Exploration, Inc., a Texas
corporation (the "Company"), in connection with the registration under the
Securities Act of 1933, as amended (the "Act"), by the Company of the offering

of the Company to be issued to holders of partnership interests of Enserch
Exploration Partners, Ltd. pursuant to the terms of that certain Enserch
Exploration Partners, Ltd. Plan of Complete Liquidation (the "Plan of
Liquidation").  A registration statement on Form S-4 (the "Registration
Statement") has been filed with the Securities and Exchange Commission (the
"Commission") concurrent with the delivery of this opinion.

     In connection with the rendering of this opinion, we have examined and
relied upon the originals or copies, certified to our satisfaction, of such
documents, certificates and instruments as we have deemed necessary for the
expression of the opinions expressed herein, including the Articles of
Incorporation, as amended, and the Bylaws of the Company, the Plan of
Liquidation, copies of resolutions of the Board of Directors of the Company
authorizing the offering and the issuance of the Shares and the Registration
Statement, as amended, and all exhibits thereto. In making the foregoing
examinations, we have assumed the genuineness of all signatures on original
documents, the authenticity of all documents submitted to us as originals and
the conformity to original documents of all copies submitted to us.

     Based upon the foregoing examination, subject to the comments and
exceptions herein stated, and limited in all respects to the laws of the State
of Texas and the laws of the United States of America, and subject to
confirmation that the Commission has declared the Registration Statement
effective, it is our opinion that the Shares have been duly and validly
authorized by the Company, and when issued in accordance with the terms of the
Plan of Liquidation, the Shares will be legally issued, fully paid and
nonassessable.

Enserch Exploration Partners, Ltd.
300 South St. Paul
Dallas, Texas  75201

Gentlemen:

     We have acted as special counsel to Enserch Exploration Partners, Ltd., a
Texas limited partnership ("EP"), in connection with the federal income tax
consequences of a proposed reorganization and restructuring of EP (the
"Reorganization") to members of the public (collectively) that own partnership
interests in EP ("Public Unitholders").  The Reorganization also involves EP
Operating Limited Partnership, a Texas limited Partnership ("EPO"),  ENSERCH
Corporation, a Texas corporation ("EC"), and its controlled corporate
subsidiaries and their controlled partnerships, including but not limited to,
Enserch Exploration, Inc., a Delaware corporation ("EEI"), but not EP and EPO
(collectively with EC, the "EC Companies").  The Reorganization contemplates,
among other things, the formation of two new Texas corporations ("Newco") and
("Newsub"), the transfer of EPO partnership interests to Newco and Newsub, the
merger and dissolution of EPO and Newsub into Newco followed by the liquidation
and dissolution of EP.  As a result, the Public Unitholders will receive shares
of Newco Common Stock in exchange for their outstanding partnership interests,
which are represented by depositary units reflecting limited partnership
interests in EP (the "Units").  The opinion that follows addresses the federal
income tax consequences of the Reorganization that should be considered by the
Public Unitholders.  It does not address or otherwise comment upon all of the
federal tax aspects of the Reorganization and does not set forth any of the
federal income tax consequences as they may affect any of the EC Companies.
Capitalized terms used herein but not defined have the meanings ascribed to them
in the Prospectus/Information Statement (the "Information Statement") of Newco
filed on December 9, 1994, under the Securities Act of 1933, as amended (the
"Act").

     The opinions hereinafter set forth are based on the provisions of the
Internal Revenue Code of 1986, as amended (the "Code"), existing and proposed
Treasury Regulations (the "Regulations") thereunder, current administrative
rulings and court decisions, and certain factual representations made by EC
Companies and assumptions that are set forth herein.  There can
<PAGE>
 
Enserch Exploration Partners, Ltd.

Page 2

be no assurance that the legal authorities upon which this opinion is based will
not change, perhaps retroactively, that the representations and factual
assumptions underlying this opinion will be accurate, or that there will not be
future changes in circumstances which affect this opinion.  This opinion is
subject to and conditioned upon the receipt, prior to the effective date of the
Reorganization, of certain written representations by certain EC Companies
satisfactory to counsel (the "Representation Letter").  The initial and
continuing accuracy of the representations in the Representation Letter
constitutes an integral basis for this opinion and this opinion is conditioned
upon the initial and continued accuracy of these representations.  We have not
independently undertaken verification of these representations.  There can be no
assurance that the Internal Revenue Service (the "Service") will not disagree
with the conclusions herein expressed and no ruling from the Service on any
aspect of the Reorganization has or will be requested.

     In rendering this opinion, we have examined such documents as we have
deemed relevant or necessary, including (i) various financial analyses of the
Reorganization, (ii) the Amended and Restated Agreement of Limited Partnership
of Enserch Exploration Partners, Ltd., including any amendments thereto, (the
"EP Partnership Agreement"), (iii) the Amended and Restated Agreement of Limited
Partnership of EP Operating Company, including any amendments thereto (the "EPO
Partnership Agreement"), (iv) the plan of liquidation of EP, (v) the Information
Statement, and (vi) such other documents as we have deemed necessary or
appropriate in order to enable us to render this opinion.  In our examination,
we have assumed the genuineness of all signatures, the due execution and
delivery of all documents, the legal capacity of all natural persons and the
authenticity of all documents.  We have also assumed and relied upon the initial
and continuing accuracy of the representations set forth in the Representation
Letter.  We, however, have not independently verified the representations
contained in the Representation Letter.  This opinion is given at the date
hereof and we undertake no responsibility to advise you of future developments
in the application or interpretation of relevant federal income tax laws.

     EP is a publicly traded Texas limited partnership which is approximately
99.2 percent owned in various proportions by the EC Companies.  EEI is the
Managing General Partner of EP and EPO and holds a 1 percent general partnership
interest in EP and a .99 percent general partnership interest in EPO.  EEI is a
wholly-owned corporate subsidiary of EC.  EC holds a .01 percent Special General
Partnership interest in EPO.  Enserch Processing Partners, Ltd., a Texas limited
partnership ("EPPL") in which EC directly or indirectly owns all of the general
and limited partner interests, owns a 98.2 percent limited partner interest in
EP.  The Public Unitholders own an approximate .8 percent limited partnership
interest in EP, which is represented by the Units.  The Public Unitholders are
not affiliated with EC or any of the EC Companies.  EP owns a 99 percent limited
partnership interest in EPO.  Under the Reorganization, the partnership
structure of EP and EPO will be converted from a tiered
<PAGE>
 
Enserch Exploration Partners, Ltd.
December 9, 1994
Page 3

partnership into a corporation in the form of Newco.  The significant steps in
the Reorganization as it relates to the Public Unitholders are as follows:

     1.  EP will transfer a 1 percent limited partnership interest in EPO to the
capital of Newco for Newco Common Stock, which in turn will contribute that
interest to Newsub in exchange for all of the issued stock of Newsub.

     2.  Thereafter, EP will contribute its remaining 98 percent limited
partnership interest in EPO to Newco for additional Newco Common Stock and EC
and EEI will contribute their general partnership interests in EPO to Newco in
exchange for Newco Common Stock.

     3.  EPO and Newsub will merge into Newco pursuant to the applicable
provisions of the Texas Revised Limited Partnership Act and the Texas Business
Corporations Act.

     4.  Thereafter, EP will be completely liquidated and will distribute Newco
Common Stock to the Public Unitholders and distribute Newco Common Stock and
other assets to the EC Companies that hold partnership interests in EP.

     Immediately before the liquidation of EP, the capital accounts of its
partners, including the Public Unitholders, will be adjusted to reflect their
share of any unrealized gain in EP's assets, including the Newco Common Stock EP
received upon the transfer of its 99 percent limited partnership interest in EPO
to the capital of Newco.  The partnership agreement of EP was amended to include
a special allocation to the Public Unitholders of unrealized appreciation in
EP's partnership interest in EPO.  Pursuant to EP's plan of liquidation, EP will
be liquidated, with (i) Newco Common Stock being distributed to the Public
Unitholders and the EC Companies that are partners of EP pro rata in relation to
their interest in EP, (ii) EEI receiving EP's interest in, and assuming EP's
obligations under, the Equipment Leases, and (iii) the EC Companies assuming
approximately $395 million in aggregate principal amount of debt of EP owed to
certain EC Companies and to Newco, plus accrued interest.  Any assets (including
cash) remaining after satisfaction of all obligations of EP will be contributed
to the capital of Newco.  EPO and EP will both file federal partnership tax
returns for 1994 beginning January 1, 1994, and ending upon the effective date
of the merger of EPO and the effective date of the liquidation of EP,
respectively.

     Based on the foregoing, it is our opinion that the material federal income
tax consequences with respect to the Public Unitholders and Newco are as
follows:

     1.  Pre-Reorganization Operations of EP.  The income and deductions of EP
that accrue during the portion of 1994 prior to the Reorganization will be
allocated among its partners, and these allocations and adjustments will be made
in essentially the same manner as
<PAGE>
 
Enserch Exploration Partners, Ltd.
December 9, 1994
Page 4

they would have been made absent the Reorganization.  Each Public Unitholder's
capital account and tax basis in his Units will be adjusted by these
allocations.  Each Public Unitholder will receive a Schedule K-1 for 1994
reflecting the income and deductions allocated to him for the portion of 1994
during which he was a Unitholder, even if he sells his Units prior to the
Reorganization.

     2.  Pre-Reorganization Sale of Units.  The tax consequences to a Public
Unitholder who sells Units prior to the Reorganization will not be affected by
the Reorganization.  The tax consequences of any such sale are as follows:

     a.  Character and Amount of Gain or Loss.  A Public Unitholder will
     recognize both ordinary income and capital gain or loss on a sale of Units.
     The ordinary income component will be equal to the amount of ordinary
     income that would have been allocated to the Public Unitholder in respect
     of the Units that are sold if EP and EPO had sold all of their assets.  The
     ordinary income element if EP and EPO had sold all of their assets would be
     that amount of gain which is attributable to Section 751 assets (unrealized
     receivables and substantially appreciated inventory), including recapture
     of depreciation and intangible drilling and development costs.  The capital
     gain or loss amount will equal the difference between the amount realized
     from the sale of the Units (reduced by the portion resulting in ordinary
     income) and the Public Unitholder's adjusted tax basis in the Units that
     are sold (reduced by the portion allocable to the ordinary income
     component).  If the ordinary income element realized on the sale of his
     Units reduces the amount realized on the sale of his Units below his tax
     basis, a Public Unitholder will realize a capital loss on the sale portion
     of his Units.  A Public Unitholder's capital gain or loss will be treated
     as long-term capital gain or loss if the Public Unitholder owned the Units
     that were sold for more than one year prior to the sale and the Public
     Unitholder held his Units as capital assets.  If the Unitholder had a
     holding period of one year or less, the Public Unitholder's capital gain or
     loss will be treated as short-term capital gain or loss.  If a Public
     Unitholder sells less than all of his Units, for purposes of determining
     gain or loss on the Units sold, his adjusted basis in all of his Units held
     immediately prior to the sale must be allocated among the Units sold and
     the Units retained based on the ratio of the fair market value of the Units
     sold over the fair market value of all his Units immediately before the
     sale.

     b.  Suspended Deductions.  A Public Unitholder may be limited in his
     ability to utilize previously suspended deductions and losses on a sale of
     his Units prior to the Reorganization.  Utilization of previously suspended
     deductions and losses is discussed below:
<PAGE>
 
Enserch Exploration Partners, Ltd.
December 9, 1994
Page 5

          (1)  Any losses previously allocated to a Public Unitholder that he
               has not been allowed to use through the date of sale of his Units
               because of the Code Section 704(d) basis limitation rule will be
               lost and cannot be utilized to offset any gain realized on the
               sale.  Code Section 704(d) limits the use of partnership losses
               to a partner's adjusted basis in his partnership interest.

          (2)  Any losses previously allocated to a Public Unitholder that he
               has not been allowed to use because of the at-risk limitations
               can (subject to (b)(3) below), under Proposed Regulation Sections
               1.465-66 and 1.465-12, be used to the extent of any gain
               recognized on the sale of the Units.

          (3)  Any losses previously allocated to a Public Unitholder that are
               not subject to the limitations set forth in (1) or (2) above but
               that he has not been allowed to use because of the passive loss
               limitations ("suspended passive losses") can be used in full if
               the Public Unitholder sells all his Units to an unrelated person
               in a transaction in which all gain or loss is recognized.

          (4)  A Public Unitholder who sells less than all of his Units will be
               entitled to deduct suspended passive losses to the extent of any
               gain recognized on the sale, if the Public Unitholder is a
               calendar year taxpayer and sells either a portion or
               substantially all of his Units before the effective date of the
               Reorganization in 1994.  Final Regulations recently issued
               indicate that for taxable years beginning after October 4, 1994,
               a Public Unitholder will have to sell substantially all of his
               Units in order to utilize any suspended passive losses.  In
               addition, a Public Unitholder's suspended passive losses are only
               deductible to the extent that the gain recognized on such a
               partial sale is allocable to passive activities.  The portion of
               any such gain that is allocable to passive activities will be
               equal to the amount determined by multiplying the Public
               Unitholder's gain by a fraction, the numerator of which is the
               net gain that would have been allocated to the Public Unitholder
               if EPO had sold all of its appreciated trade or business and
               rental activities for their fair market value and the denominator
               of which is the amount of net gain that would have been allocated
               to the Public Unitholder if EPO had sold all of its appreciated
               activities, including investment activities, for their fair
               market value.  Based upon representations of EEI, as Managing
               General Partner of EP, all of the Public Unitholder's gain will
               be properly allocable to passive activities
<PAGE>
 
Enserch Exploration Partners, Ltd.
December 9, 1994
Page 6

               because all of EPO's appreciated assets are used in its business
               or rental activities and not investment activities.

     3.   Reorganization Consequences.  The material federal income tax
consequences to a Public Unitholder who receives shares of Newco Common Stock as
a result of the Reorganization will be as follows:

     a.  General Non-Recognition.  Public Unitholders will not recognize any
     gain or loss on the Reorganization, except as otherwise stated below.

     b.  Non-Recognition on Newco Contribution.  EP, EEI and EC's contribution
     of all of their partnership interests in EPO to Newco (the "Newco
     Contribution") will be tax-free and will be tax-free to the Public
     Unitholders unless (i) EP's tax basis in its partnership interest in EPO is
     less than EP's share of EPO's liabilities transferred to Newco, as
     determined pursuant to Section 752 of the Code, in which case EP will
     recognize gain which will be partially allocated to the Public Unitholders
     or (ii) a Public Unitholder's tax basis in his Units is less than his share
     of EPO's liabilities, as determined pursuant to Section 752 of the Code,
     immediately before the Newco Contribution.  Based upon representations of
     EEI, as Managing General Partner of EP, no Public Unitholder will recognize
     gain on the Newco Contribution or the Reorganization.

     c.  Liquidation Premium Allocation.  In connection with the Reorganization,
     the EP Partnership Agreement is being amended to include a special
     allocation to the Public Unitholders of unrealized appreciation in EP's
     partnership interest in EPO (the "Liquidation Premium Allocation") which
     results in positive capital account adjustments but has no effect on a
     Public Unitholder's tax basis.  Because of the increased value attributable
     to the Public Unitholders' Units, the assumption by the EC Companies of all
     of EP's liabilities will not reduce the Public Unitholders' exchange ratio
     of one share of Newco Common Stock for each Unit held.  This Liquidation
     Premium Allocation does not have any material tax consequences and will not
     cause the Public Unitholders to recognize any gain in connection with the
     Reorganization.  The assumption by the EC Companies as part of the
     Reorganization of $395 million of EP liabilities will have no tax
     consequences to the Public Unitholders or the EC Companies.

     d.  Tax Basis.  A Public Unitholder's aggregate tax basis in all shares of
     Newco Common Stock received in the Reorganization will equal the Public
     Unitholder's aggregate tax basis in his Units, as adjusted (i) for 1994
     operations to the date of the Reorganization and (ii) by excluding any
     share of EP debts a Public Unitholder had previously included in his basis
     in his Units.  This basis will be prorated among all
<PAGE>
 
Enserch Exploration Partners, Ltd.
December 9, 1994
Page 7

     shares of Newco Common Stock received by the Public Unitholder.  To the
     extent any Newco Common Stock distributed to a Public Unitholder results in
     a tax basis lower than its fair market value, gain will be recognized upon
     the subsequent sale or other taxable disposition of that Newco Common
     Stock.  Correspondingly, to the extent any Newco Common Stock distributed
     to a Public Unitholder results in a tax basis greater than its fair market
     value, loss may be recognized upon the subsequent sale or other taxable
     disposition of that Newco Common Stock.

     e.  Holding Period.  For holding period purposes, each share of Newco
     Common Stock will be divided into two parts.  One part will be the portion
     of the value of the share that is attributable to EPO's Code Section 751
     assets that are neither capital assets nor Section 1231 assets (ordinary
     income assets).  The holding period for this part will begin on the day
     following the Newco Contribution.  The other part will include the holding
     period EP has in its partnership interest in EPO.  This other part will
     have satisfied the long-term capital gain requirement for a holding period
     of more than one year and will therefore qualify a portion of each share
     attributable to this other part for long-term capital gain treatment when
     sold (assuming that the Newco Common Stock is held as a capital asset).  As
     a result of this multiple holding period rule, a Public Unitholder who
     receives Newco Common Stock in the Reorganization has to hold each share
     for at least one year to insure that all gain upon its sale will be long-
     term capital gain.  The holding period that a Public Unitholder has for his
     Units is totally disregarded in determining the Public Unitholder's holding
     period for Newco Common Stock received in the Reorganization.

     f.  Suspended Deductions.  Any operating loss allocated to a Public
     Unitholder in prior years or during 1994 that has not been used because of
     the at-risk limitations cannot be used since no taxable gain will be
     recognized on the Reorganization.  A Public Unitholder also will not be
     entitled to deduct suspended passive losses since no gain will be
     recognized by the Public Unitholders as a result of the Reorganization.
     Any passive losses not so used may be used thereafter only as provided
     below under "Sale of Shares."  Any suspended at-risk loss not so used, and
     any unused loss suspended by a basis limitation, will be eliminated and be
     unavailable to Public Unitholders thereafter in connection with a sale of
     Newco Common Stock received in the Reorganization.

     g.  Sale of Shares.  A Public Unitholder who receives shares of Newco
     Common Stock in the Reorganization and thereafter sells those shares will
     recognize gain or loss equal to the difference between the amount realized
     on the sale and the Public Unitholder's tax basis in the shares sold.  A
     shareholder will be able to utilize the entire amount of his suspended
     passive losses upon the sale of all of his Newco Common Stock to an
     unrelated person in a transaction in which all gain or loss is recognized.
     Recently
<PAGE>
 
Enserch Exploration Partners, Ltd.
December 9, 1994
Page 8

     issued Regulations also indicate that a pro rata portion of a shareholder's
     passive losses can be utilized to offset gain on the sale of Newco Common
     Stock if the shareholder sells substantially all of his stock to an
     unrelated party.  Depending on the holding period of the Newco Common Stock
     (see "Holding Period" above), a shareholder will realize long or short term
     gain or loss or both upon a sale of shares.

     h.  Ownership of Shares.  After the Reorganization, a shareholder will be
     taxed only on distributions received from Newco, if any.  Nonliquidating
     distributions will be taxable as dividends to the extent of any current or
     accumulated earnings and profits of Newco.  Any nonliquidating
     distributions in excess of the current or accumulated earnings and profits
     of Newco and any liquidating distributions will be treated as a tax free
     return of capital to the extent of the shareholder's basis in his shares of
     Newco Common Stock and as capital gain to the extent of the excess,
     assuming that the shares are held as capital assets.  Any losses incurred
     by Newco will not flow through to shareholders for use on their income tax
     returns, but instead will be used by Newco in filing its corporate income
     tax returns.  Although there are no Regulations, rulings or cases covering
     the point, counsel is of the opinion that a former Public Unitholder will
     not be entitled to use any suspended passive losses allocable to his shares
     to offset any dividends received from Newco.

     i.  Legislation.   Under current law, a partner recognizes gain to the
     extent that money distributed by a partnership exceeds the basis of his
     partnership interest immediately before the distribution.  Congress,
     however, has recently passed legislation that will, under certain
     circumstances, treat a portion of the value of the common stock distributed
     to a partner as a distribution of money.  Absent any adverse Regulations
     which apply retroactively, it appears that this legislation will not apply
     to EP's liquidating distribution of Newco Common Stock to the Public
     Unitholders because the legislation does not apply to publicly traded
     partnership liquidations like EP until after 1997.  No assurance can be
     given, however, that the Regulations, when issued, will not be retroactive
     and apply in a materially adverse way.

     4.   Newco Consequences.

     a.  The Newco Contribution and Merger.  The contribution by EP of a 1
     percent limited partnership interest in EPO to Newco and Newco's
     contribution of that partnership interest to Newsub will both be tax-free
     to Newco and Newsub.  Thereafter, the contribution by EP, EEI and EC of the
     remaining partnership interests in EPO to Newco will also be tax-free to
     Newco although such contribution will constitute a constructive termination
     of EPO for federal tax purposes.  As a result of such constructive
     termination, EPO will be deemed to have distributed all of its assets and
<PAGE>
 
Enserch Exploration Partners, Ltd.
December 9, 1994
Page 9

     liabilities pro rata to Newco and Newsub, and Newco and Newsub will be
     deemed to have recontributed such assets and liabilities to a new
     partnership.  The constructive termination and re-contribution will have no
     material adverse tax consequences unless the amount of cash constructively
     distributed to Newco and Newsub exceeds their respective tax bases in their
     partnership interests.  If the cash distributed does exceed their
     respective tax bases, gain will be recognized by Newco and Newsub to the
     extent of such excess.

          The merger of EPO and Newsub into Newco (the "Merger") will be treated
     as a transfer of assets and liabilities from EPO to Newco and from Newsub
     to Newco and the aggregate tax basis of Newco in the assets transferred
     will be equal to the tax basis that Newco and Newsub had in their
     respective partnership interests in EPO.  Newco's tax basis in a
     substantial portion of its assets will generate future tax deductions for
     Newco.  Although Public Unitholders with relatively higher bases in their
     Units than other Public Unitholders may be viewed (through EP's and EPO's
     Code Section 754 election) as having a greater share of such basis, no
     consideration has been given to this expected future tax benefit in
     arriving at the number of shares of Newco Common Stock received by each
     Public Unitholder.  Newco's holding period for each asset acquired in the
     Merger will equal the holding period that EPO had in its assets prior to
     the constructive termination of EPO.

     b.  Post-Reorganization Operations.  Following the Newco Contribution, the
     income and deductions attributable to the assets and liabilities previously
     held by EPO will be included in the corporate tax return filed by Newco,
     and Newco will pay taxes on any taxable profits it recognizes from time to
     time.  Additionally, net operating losses incurred by Newco after the Newco
     Contribution and the Merger will be available to offset Newco's income in
     subsequent years.

     5.   Other Taxation.  The above opinions deal exclusively with federal
income tax consequences.  We have not attempted to and give no opinion with
respect to any state or local tax that may be imposed on the Public Unitholders,
the EC Companies or Newco as a result of (i) any sale of Units prior to the
Reorganization, (ii) the Reorganization, or (iii) sales or other dispositions of
Newco Common Stock subsequent to the Reorganization.

     This opinion is provided to you and no other person or entity can rely upon
this opinion except you and the Public Unitholders.  We hereby consent to the
use of this opinion as an exhibit to the Information Statement and to the
reference to this Firm in the Information Statement under the captions "SUMMARY-
- -SUMMARY OF MATERIAL FEDERAL INCOME TAX CONSEQUENCES" and "FEDERAL INCOME TAX
CONSIDERATIONS".  In giving this consent we do not thereby admit that we come
within the category of persons whose consent

                         NEW ENSERCH EXPLORATION, INC.

                           1994 STOCK INCENTIVE PLAN


ARTICLE I.  PURPOSE

     The purpose of the 1994 Stock Incentive Plan (the "Plan") is to promote the
long-term success of New Enserch Exploration, Inc. (the "Company," which
includes its subsidiaries and affiliates) by providing a means through which the
Company can attract and retain key officers and employees who can contribute
materially to that success.  Such purpose shall be accomplished under the Plan
by the (a) grants of stock Options ("Options") to purchase shares of the Common
Stock of the Company ("Shares"), (b) awards of Restricted Stock ("Restricted
Stock"), or (c) a combination of both.

ARTICLE II.  EFFECTIVE DATE

     The Plan shall become effective on November 15, 1994, (the "Effective
Date") subject to approval of the Plan by the affirmative vote of the holders of
a majority of the Shares outstanding and entitled to vote.

ARTICLE III.  ADMINISTRATION

     The Compensation Committee (the "Committee") of the Board of Directors of
the Company (the "Board"), shall have the sole responsibility for the
administration of the Plan.  The Committee shall establish any Administrative
Guidelines necessary or advisable for the administration of the Plan.  The
Committee shall have the authority to amend or rescind the Administrative
Guidelines and shall have full authority with regard to the interpretation of
the Administrative Guidelines or any other matters relating to the Plan.  The
Committee shall act by vote or consent of a majority of its members.  All acts,
determinations and decisions of the Committee shall be final and conclusive as
to the parties concerned.

ARTICLE IV.  ELIGIBILITY

     Eligibility for participation in the Plan shall be confined to a limited
number of persons whom the Committee, in its sole discretion, shall select who
can make a meaningful contribution to the Company's success and who are (a)
officers of the Company, whether or not such officers are directly compensated
by the Company for their services, (including an officer who may also be a
director of the Company) or (b) persons in managerial or other key positions in
the Company.  No Option or award of Restricted Stock shall be granted to any
member of the Committee.  The Committee shall, from time to time and in its sole
discretion, select from such eligible persons, those to whom Options shall be
granted and awards of Restricted Stock shall be made and shall determine the
number of shares to be subject to each Option or award of Restricted Stock.

ARTICLE V.  RESERVE OF SHARES

     (a)  A total of 2,000,000 Shares is the maximum number of Shares reserved
for the Plan, subject to the adjustments authorized by Subparagraphs (b) and (c)
below.  Shares available under the Plan for grants of Options or awards of
Restricted Stock may consist either in whole or in part of authorized but
unissued Shares or Shares held in the treasury of the Company.
<PAGE>
 
     (b)  The number of Shares held in reserve for the Plan, the number of
Shares subject to Option that may be granted to any individual in any calendar
year, the number of shares of Restricted Stock that may be awarded to an
Executive Officer with respect to all performance periods beginning in any
calendar year, the number of Shares and the Option price for Shares covered by
each outstanding Option, and the number of Shares covered by each outstanding
award of Restricted Stock shall be proportionately adjusted for any increase or
decrease in the number of issued Shares resulting from a subdivision or
consolidation of the issued Shares and may, in the absolute discretion of the
Board, be similarly adjusted for any other capital adjustment (including the
reclassification of Shares or recapitalization or reorganization of the
Company), the payment of a stock dividend or the distribution to holders of the
Shares of rights, warrants, assets or evidences of indebtedness.

     (c)  If an Option as to any Shares expires, terminates, ceases to be
exercisable or is surrendered before being exercised in full, or an award of
Restricted Stock is forfeited (where the forfeiting participant received no
benefits of ownership), the number of Shares that were subject to the Option but
that were not transferred pursuant to the Option or the number of Shares covered
by the forfeited award of Restricted Stock shall, unless the Plan shall have
been terminated, again be available for the granting of Options or the award of
Restricted Stock, subject to the aggregate maximum stated in Subparagraph (a)
above.

ARTICLE VI.  TERMS AND CONDITIONS OF OPTIONS

     One or more Options can be granted to any person eligible to receive such a
grant under Article IV.  The maximum number of Shares subject of Options that
can be granted to any one individual during any calendar year shall not exceed
80,000 shares (subject to adjustment pursuant to Article V hereof).  Each Option
granted pursuant to the Plan shall be evidenced by a stock option agreement (the
"Agreement") between the Company and the person to whom the Option is granted
(the "Optionee"), which Agreements need not be identical to each other but shall
comply with and be subject to the following terms and conditions:

     (a)  Option Price:  The Option price per Share shall be set at the date of
grant ("Date of Grant") by the Committee but shall in no instance be less than
the Fair Market Value on the date the Option is granted.  As used in the Plan
(unless a different method of calculation is required by applicable law), "Fair
Market Value" on any date shall mean (i) the average of the high and low prices
per share of the Shares as reported in the New York Stock Exchange Composite
Transactions Report (or any other consolidated transactions reporting system
which subsequently may replace such Composite Transactions Report) (the
"Consolidated Tape") for the New York Stock Exchange (the "NYSE") on the date as
of which the determination is being made or, if there are no sales on such date,
in accordance with applicable Internal Revenue Service Regulations relating to
the determination of fair market value of stock options or (ii) in the event
that the Shares are not listed for trading on the NYSE, an amount determined in
accordance with standards adopted by the Committee.

     (b)  Duration of Options:  Unless Subparagraph (f) of this Article VI
applies, each Option granted under the Plan shall expire and all rights to
purchase Shares pursuant thereto shall cease on the tenth anniversary of the
Date of Grant of the Option (the "Expiration Date").

     (c)  Vesting of Options:  Each Option granted hereunder may only be
exercised to the extent that the Optionee is vested in such Option.  An Optionee
shall vest separately in each Option granted hereunder in accordance with a
schedule determined by the Committee, in its sole discretion, which will

                                       2
<PAGE>
 
be incorporated in the Agreement.  Unless otherwise determined by the Committee,
each Agreement will provide that the Option vests in accordance with the
following schedule:

<TABLE> 
<CAPTION> 

Number of years the Optionee has remained
in the employ of the Company                             Extent to which the
following the of the Option                               Option is vested
- -----------------------------------------                -------------------
<S>                                                              <C>

At least two but less than three .............................    50%
At least three but less than four ............................    75%
Four or more .................................................   100%

</TABLE> 

Anything contained in this Subparagraph to the contrary notwithstanding, an
Optionee shall become fully (100%) vested in each of his or her Options upon his
or her termination of employment with the Company for reasons of death,
Disability or Retirement at or after age 60, upon the sale of a Subsidiary of
the Company to an unaffiliated company such that he or she no longer remains in
the employ of the Company or, if in the sole discretion of the Committee, the
Committee determines that acceleration of the Option vesting schedule would be
desirable for the Company.
 
     (d)  Merger, Consolidation, Etc.:  In the event that the Company shall,
pursuant to action by its Board, at any time propose to merge into, consolidate
with or sell or otherwise transfer all or substantially all of its assets to
another corporation and provision is not made pursuant to the terms of such
transaction for the assumption by the surviving, resulting or acquiring
corporation of outstanding Options, or for the substitution of new Options with
substantially equivalent benefit therefor, each outstanding Option shall become
fully (100%) vested.  The Committee shall advise each Optionee, in writing, of
the manner and terms under which such fully vested Options shall be exercised.

     (e)  Exercise of Options:

          (i)  Unless otherwise prohibited by Subparagraph (f) or the terms of
     this Plan, an Optionee may exercise, in whole or in part, the vested
     portion of an Option at any time by delivering to the Corporate Secretary
     of the Company written notice specifying the number of Shares with respect
     to which the Option is being exercised, together with payment in full of
     the purchase price of such Shares plus any federal, state or local taxes
     for which the Company has a withholding obligation in connection with such
     exercise.  In addition to payment in cash, payment may be made by the
     exchange of Common Stock of the Company previously acquired by the Optionee
     and held for at least six months and having a Fair Market Value on the date
     of exercise equal to the price for which the Shares may be purchased
     pursuant to the Option.  The Committee may, in its sole discretion,
     authorize such payment, in whole or in part, in any other form as may be
     approved by the Board and in a manner authorized by law.

          (ii) An Optionee may elect to satisfy any withholding due on the
     exercise of an Option either (a) in cash (the "cash method") or (b) by the
     retention by the Company of a number of Shares out of the Shares being
     purchased having a Fair Market Value equal to the amount to be withheld
     (the "Share retention method").  The Compensation Committee shall
     determine, from time to time, the amount to be withheld and the time and
     manner in which an Optionee may elect

                                       3
<PAGE>
 
     to satisfy such withholding obligation.  Such amount shall be not less than
     the minimum withholding obligation of the Company  or not more than the
     amount determined by application of the maximum tax in effect for
     individuals under applicable federal, state or local tax law.  Under the
     "Share retention method," the amount to be withheld, subject to the
     discretion of the Committee, shall be the amount designated by such
     Optionee within such maximum and minimum amounts.

     (f)  Termination of Employment:  Unless otherwise determined by the
Committee, the following rules shall apply in the event of an Optionee's
termination of employment with the Company:

          (i)   In the event of an Optionee's termination of employment with the
     Company either (1) for cause or (2) voluntarily on the part of the
     Optionee, without the written consent of the Company and for reasons other
     than death, Disability or Retirement (as such terms are defined in
     Subparagraphs (f)(iv) and (v) hereof), his or her Options shall immediately
     terminate.

          (ii)  In the event of an Optionee's termination of employment with the
     Company under circumstances other than those specified in Subparagraph
     (f)(i) hereof and for reasons other than death, Disability or Retirement
     (as defined in Subparagraphs (f)(iv) and (v) hereof), such Options shall
     terminate on the earlier of 90 days after the date of such termination of
     employment or the Option's Expiration Date.

          (iii) In the event of the death of an Optionee while he or she is
     employed by the Company or during a period when Subparagraph (f)(ii),
     (f)(iv) or (f)(v) hereof is applicable, such Options shall terminate on the
     earlier of the first anniversary of the Optionee's death or the Option's
     Expiration Date.

          (iv)  In the event of the Optionee's termination of employment with
     the Company on account of a Disability, as defined in the Internal Revenue
     Code, such Options shall terminate on the earlier of the first anniversary
     of the Optionee's termination of employment or the Option's Expiration
     Date.

          (v)   In the event of the termination of employment of an Optionee,
     other than discharge for cause, after age 65 or on or after age 60 pursuant
     to the terms of any retirement plan maintained by the Company in which the
     Optionee participates (either of which terminations shall constitute
     "Retirement"), such Options shall terminate on the earlier of three years
     after the date of such termination of employment or the Option's Expiration
     Date, unless the retiring Optionee remains a director of the Company.  In
     that event, this provision will be triggered when such directorship
     terminates.

          (vi)  Anything contained in this Subparagraph (f) to the contrary
     notwithstanding, an Option may only be exercised following the Optionee's
     termination of employment with the Company for reasons other than death,
     Disability or Retirement if and to the extent that such Option was
     exercisable immediately prior to such termination of employment.

          (vii) An Optionee's transfer of employment between the Company and
     (a) its subsidiaries or affiliates or (b) ENSERCH Corporation and its
     subsidiaries and affiliates shall not constitute a termination of
     employment.  An Optionee that ceases to be an officer or employee of the
     Company while remaining an employee of ENSERCH Corporation, its
     subsidiaries or affiliates,

                                       4
<PAGE>
 
     is deemed not to have terminated his or her employment with the Company
     until such time as there is a termination of employment with ENSERCH
     Corporation, its subsidiaries or affiliates; and the Committee shall
     determine in each case whether an authorized leave of absence for military
     service or otherwise shall constitute a termination of employment.

     (g)  Nontransferability:  Options shall not be transferable other than by
will or the laws of descent and distribution, and no Option may be exercised by
anyone other than the Optionee except that, should the Optionee die or become
incapacitated, the Option may be exercised by his or her estate, legal
representative or beneficiary subject to all other terms and conditions
contained in the Plan.

     (h)  Change in Control:  Anything contained herein to the contrary
notwithstanding, an Optionee shall become fully (100%) vested in each of his or
her Options upon the occurrence of a change in control, and no Option held by an
Optionee at the time a change in control occurs or at any time thereafter shall
terminate for any reason before the Option's Expiration Date.  For this purpose,
"change in control" means one or more of the following events:

          (i)   any person within the meaning of Section 13(d) and 14(d) of the
     Securities Exchange Act of 1934 (the "1934 Act"), other than the Company or
     ENSERCH Corporation (including its subsidiaries and affiliates), has become
     the beneficial owner, within the meaning of Rule 13d-3 under the 1934 Act,
     of 50% or more of the combined voting power of the Company's then
     outstanding Common Stock or equivalent in voting power of any class or
     classes of the Company's outstanding securities ordinarily entitled to vote
     in elections of directors ("voting securities"), or

          (ii)  Shares representing 50% or more of the combined voting power of
     the Company's  voting securities are purchased pursuant to a tender offer
     or exchange offer (other than an offer by the Company, ENSERCH Corporation
     or its subsidiaries or affiliates, or

          (iii) the Shareholders of the Company have:

               (A)  approved an agreement to merge or consolidate with or into
          another corporation or an agreement to sell or otherwise dispose of
          all or substantially all of the Company's assets (including a plan of
          liquidation), or

               (B)  elected two or more persons to serve as directors of the
          Company who were not nominated and approved by the Board or a
          committee of the Board, or

          (iv)   a "change in control" of ENSERCH Corporation shall occur and
     for this purpose, a "change in control" of ENSERCH Corporation means one or
     more of the following events:

               (A)   any person within the meaning of Section 13(d) and 14(d) of
          the Securities Exchange Act of 1934 (the "1934 Act"), other than
          ENSERCH Corporation, has become the beneficial owner, within the
          meaning of Rule 13d-3 under the 1934 Act, of 20% or more of the
          combined voting power of ENSERCH Corporation's then outstanding Common
          Stock or equivalent in voting power of any class or classes of ENSERCH
          Corporation's outstanding securities ordinarily entitled to vote in
          elections of directors ("voting securities"), or

                                       5
<PAGE>
 
               (B)  shares representing 20% or more of the combined voting power
          of ENSERCH Corporation's voting securities are purchased pursuant to a
          tender offer or exchange offer (other than an offer by ENSERCH
          Corporation), or

               (C)   the Shareholders of ENSERCH Corporation have:


                    (x) approved an agreement to merge or consolidate with or
               into another corporation or an agreement to sell or otherwise
               dispose of all or substantially all of ENSERCH Corporation's
               assets (including a plan of liquidation), or

                    (y) elected two or more persons to serve as directors of
               ENSERCH Corporation who were not nominated and approved by the
               ENSERCH Corporation Directors' Nominating Committee and approved
               by the ENSERCH Corporation Board of Directors.

ARTICLE VII.  ISSUANCE OF SHARES:  RESTRICTIONS

     Subject to the conditions and restrictions provided in this Article VII,
the Company shall, as soon as practicable after an Option has been exercised in
whole or in part, deliver to the Optionee a certificate, registered in the name
of such Optionee, for the number of Shares with respect to which the Option has
been exercised less any Shares which are to be retained in accordance with
Article VI(e) to satisfy tax withholding requirements. The Company may legend
any stock certificate issued hereunder to reflect any restrictions necessary
under the terms of any federal or state laws or regulations thereunder.

ARTICLE VIII.  RIGHTS AS SHAREHOLDER AND EMPLOYEE

     No Optionee shall have any rights as a Shareholder of the Company with
respect to any Shares prior to the date of issuance to him or her of the
certificate or certificates for such Shares.  Neither the Plan nor any Option
granted or Restricted Stock awarded under the Plan shall confer upon the
Optionee any right to continue in the employment of the Company.

ARTICLE IX.  SUBSTITUTE OPTIONS

     Anything contained herein to the contrary not withstanding, Options may, at
the discretion of the Committee, be granted under the Plan in substitution for
Options to purchase Shares of capital stock of another corporation which is
merged into, consolidated with, or all or a substantial portion of the property
or stock which is acquired by, the Company. The terms, provisions and benefits
to Optionees of such substitute Options may be identical in all respects to the
terms, provisions and benefits to Optionees of the Options of the other
corporation on the date of substitution, except that such substitute Options
shall provide for the purchase of Shares instead of shares of such other
corporation.

ARTICLE X.  RESTRICTED STOCK

     (a)  Awards to Eligible Participants:  The Committee may make awards of
Restricted Stock to any eligible participant, for no cash consideration, for
such minimum consideration as may be required by applicable law, or for such
other consideration as may be specified by the award (an "Award").  The

                                       6
<PAGE>
 
terms and conditions of Restricted Stock, including the terms of the release of
restrictions which may be performance-based, time-based, or a combination of
both, shall be specified by the Award. The Committee, in its sole discretion,
shall determine what rights, if any, the person to whom an award of Restricted
Stock is made shall have in the Restricted Stock during the restriction period
and the restrictions applicable to the particular Award, including whether the
holder of the Restricted Stock shall have the right to vote the shares or
receive all dividends and other distributions applicable to the Shares.  The
Committee shall determine when the restrictions shall lapse, or expire and the
conditions, if any, under which the Restricted Stock will be forfeited or sold
back to the Company.  Each award of Restricted Stock may have different
restrictions and conditions.  The Committee, in its discretion, may
prospectively change the restriction period and the restrictions applicable to
any particular award of Restricted Stock.  Restricted Stock may not be
transferred or sold by the recipient until the restrictions specified in the
Award expire.

     (b)  Issuance of Stock:  Any Restricted Stock awarded hereunder may be
evidenced in such manner as the Committee, in its sole discretion, shall deem
appropriate, including, without limitation, book-entry registration or issuance
of a stock certificate or certificates.  In the event any stock certificate is
issued in respect of shares of Restricted Stock awarded hereunder, such
certificate shall bear an appropriate legend with respect to the restrictions
applicable to such Award.  The Compensation Committee may also require as a
condition to the issuance of any such certificate the delivery of an agreement
in writing between the Company and the recipient in form and substance as shall
be approved by the Compensation Committee (a "Restricted Stock Agreement").  The
Company may retain, at its option, the physical custody of the Restricted Stock
during the restriction period or require that the Restricted Stock be placed in
an escrow or trust, along with a stock power endorsed in blank, until all
restrictions are removed or expire.

     (c)  Awards to Executive Officers of Performance-Based Stock:  The
following provisions shall apply to any performance-based awards of Restricted
Stock made under this Plan to any person who has been designated by the Board of
Directors as an Executive Officer of the Company:

          (i)  the performance criteria upon which vesting of the Restricted
     Stock is contingent shall be such objective performance goals as the
     Compensation Committee shall establish in writing prior to the expiration
     of 90 days after the commencement of the performance period to which the
     performance goal or goals relate and while the outcome is substantially
     uncertain, and shall be based on total shareholder return, total
     shareholder return compared to a group of peer companies specified by the
     Compensation Committee, earnings per shares, operating unit income, or
     reserve finding effectiveness; and

          (ii) the maximum number of Shares that may be awarded to any
     Executive Officer with respect to all performance periods beginning in a
     calendar year shall not exceed 50,000 Shares (subject to adjustment
     pursuant to Article V hereof); provided, however, that the Compensation
     Committee may retain the discretion to reduce an award during or at the
     conclusion of the performance period.

     (d)  Merger, Consolidation, Etc.:  In the event that the Company shall,
pursuant to action by its Board, at any time propose to merge into, consolidate
with or sell or otherwise transfer all or substantially all of its assets to
another corporation, the restriction on transferability of the Restricted Stock
shall be lifted and the certificate(s) for the Restricted Stock shall be
delivered as soon as practicable.

                                       7
<PAGE>
 
     (e)  Change in Control:  In the event of a Change in Control of the Company
as defined in Article VI(h) hereof, the restriction on transferability of the
Restricted Stock shall be lifted and the certificate(s) for the Restricted Stock
shall be delivered as soon as practicable.

ARTICLE XI.  TERM OF THE PLAN

     Barring any action of the Board to the contrary, the Plan shall terminate
on, and no Options shall be granted or award of Restricted Stock made after, the
tenth anniversary of the Effective Date.  The provisions of the Plan, however,
shall continue thereafter to govern all Options theretofore granted until the
exercise, expiration or cancellations of such Options and to govern all awards
of Restricted Stock until all restrictions have lapsed or such Shares have been
forfeited.

ARTICLE XII.  AMENDMENT AND TERMINATION OF PLAN

     The Plan may be amended or terminated at any time by the Board except that
Article X may not be amended more than once every six months, other than to
comport with changes in the Internal Revenue Code, or the rules thereunder.
However, without further approval of the Shareholders of the Company by the
affirmative vote of the majority of the Shares entitled to vote, no amendment

date of the current Term.  The Lessee shall complete the Leased Property
Inventory Schedule for such Billing Period and deliver the same to the Lessor on
the Rent Payment Date and shall pay to the Lessor on the Rent Payment Date the
amount of Rent and the Quarterly Expense Charge, if any, specified by Lessor in
its notice to the Lessee, unless Lessor shall have notified Lessee that a
different amount of Rent and the Quarterly Expense Charge, if any, is due, in
which case Lessee shall pay such corrected amount of Rent within two (2)
Business Days of the date of the updated notice.  Failure to deliver such
written notice or inaccuracies in such notice will not excuse the Lessee from
payment of the amount of Rent and the Quarterly Expense Charge, if any, due;
provided that if Lessee makes timely payment to Lessor in accordance with such
notice and the payment amount submitted by Lessor to Lessee is determined to be
inaccurate, the incorrect payment shall not constitute an Event of Default, as
long as the correct amount is paid in full within two (2) Business Days of the
date of an updated notice of Rent due.

     (b) In addition to the Rent and Quarterly Expense Charge, if any, the
Lessee will also pay, from time to time, upon demand of the Lessor, as
additional rent ("Additional Rent") to the 

                                     -11-

calculation of Rent or otherwise paid by the Lessee):

            (i)   All out-of-pocket costs and expenses reasonably incurred by

                  execution, delivery, performance and administration of this
                  Lease and the other Operative Documents (including, without
                  limitation, reasonable attorneys' fees and expenses). The
                  Lessee also shall pay all amounts payable by the Lessor with
                  respect to the transactions contemplated hereby and by the
                  Funding Agreement and the other Operative Documents in respect
                  of the following; (A) fees and expenses of the Lessor,
                  including, without limitation, reasonable attorneys' fees and

                  limitation, fees, indemnities, expenses and compensation in
                  respect of increased costs, capital adequacy or breakage of
                  any kind or description payable under the Funding Agreement or
                  any other Operative Document; (C) out-of-pocket costs and
                  expenses incurred by the Lessor after the date of this Lease
                  (including, without limitation, reasonable attorneys' fees and
                  expenses and other expenses and disbursements reasonably
                  incurred) associated with (x) negotiating and entering into,
                  or the giving or withholding of, any future amendments,
                  supplements, waivers or consents with respect to this Lease;
                  (y) any Casualty Occurrence or termination of this Lease; and
                  (z) any Event of Default and the enforcement of the rights or
                  remedies of the Lessor under this Lease and the other
                  Operative Documents.

            (ii)  All other amounts that the Lessee agrees herein to pay other
                  than Rent and amounts described in clause (i) above.

     (c) This Lease is a completely net lease, and Rent, Additional Rent and all
other sums payable by the Lessee hereunder shall be paid without notice except
as otherwise expressly provided herein, and the Lessee shall not be entitled to
any abatement, reduction, setoff, counterclaim, defense or deduction with
respect to any Rent, Additional Rent or other sum payable hereunder.  The
obligations of the Lessee to pay Rent, Additional Rent and all other sums
payable hereunder shall not be affected by any circumstance whatsoever,
including without limitation: (a) any damage to or destruction of the Leased
Property or any part thereof by any cause whatsoever (including, without
limitation, fire, casualty or act of God or enemy or any other force majeure
event); (ii) any condemnation, including, without limitation, a temporary
condemnation of the Leased Property or any portion thereof; (iii) any
prohibition, limitation, restriction or prevention of the Lessee's use,
occupancy or enjoyment of the Leased Property or any part thereof by any Person;
(iv) any matter affecting title to the Leased Property or any portion thereof;
(v) any eviction of the Lessee from, or loss of possession by the Lessee of, the
Leased Property or any portion thereof, by reason of title paramount or
otherwise; (vi) any default by the Lessor hereunder or under any other
agreement; (vii) the invalidity or unenforceability of any provision hereof or
the impossibility or illegality of performance by the Lessor or the Lessee or
both; (viii) any action of any federal, state or local governmental authority;
or (ix) any other cause or occurrence whatsoever, whether similar or dissimilar
to the foregoing.  The Lessee shall remain obliged under this Lease in
accordance with its terms and shall not take any action to terminate, rescind or
avoid this Lease, notwithstanding any bankruptcy, insolvency, reorganization,
liquidation, dissolution or other proceeding affecting the Lessor or any action
with respect to this Lease which may be taken by any trustee, receiver or

                                     -12-

liquidator or by any court.  The Lessee waives all rights to terminate or
surrender this Lease, or to any abatement or deferment of Rent, Additional Rent
or other sums payable hereunder.  The Lessee hereby waives any and all rights
now or hereafter conferred by law or otherwise to modify or to avoid strict
compliance with its obligations under this Lease.  All payments made to the
Lessor hereunder as required hereby shall be final and irrevocable, absent
manifest error, and the Lessee shall not seek to recover any such payment or any
part thereof for any reason whatsoever, absent manifest error.  All covenants
and agreements of Lessee herein shall be performed at its cost, expense and risk
unless expressly otherwise stated.  Nothing herein shall be construed as a
guaranty by the Lessee of any residual value in the Leased Property nor to
prevent the Lessee from asserting in any legal action any mandatory
counterclaim.

     (d) The Lessee agrees that it will promptly pay all Impositions imposed
upon or levied or assessed against or relating to (i) this Lease or any future
amendment, supplement, waiver or consent requested by Lessee with respect
thereto, or the execution, delivery or performance of any thereof or the
issuance, acquisition or subsequent transfer thereto,  (ii) the Leased Property
or any portion thereof, (iii) the manufacture, financing, construction,
purchase, acceptance, possession, rejections, ownership, delivery, nondelivery,
use, operation, leasing, subleasing, condition, maintenance, repair, sale,
control, return, transfer, abandonment, redelivery or other disposition of the
Leased Property, (iv) the Lessor (and its predecessors and its and their
successors and permitted assigns and their respective  partners, officers,
directors, employees and agents) in connection with the transactions
contemplated by this Lease and the Master Lease (including all obligations of
Lessor in respect of payments or otherwise hereunder or thereunder) or imposed
or levied upon, assessed against or measured by any Rent or other sum payable
hereunder, and will furnish to the Lessor upon request copies of official
receipts or other proof evidencing such payments; provided, however, that the
                                                  --------  -------          
Lessee shall not be obligated to pay (A) any sales Taxes or other Impositions to
the extent paid by the Lessor as part of the Property Cost of any Unit of Leased
Property and financed under the Funding Agreement, (B) any Impositions  which
are based upon or measured by the Lessor's net income, or which are in
substitution for, or relieve the Lessor from, any actual Imposition based upon
or measured by the Lessor's net income (excluding, however, Impositions imposed
with respect to the payment, receipt or accrual of any indemnity payment under
this Lease), or (C) Impositions characterized under local law as franchise Taxes
(excluding, however, any value-added, license, property or similar Imposition).
The Lessee further agrees that, subject to its rights under Section 13 hereof,
it will, at its expense, do all things required to be done by the Lessor in
connection with the levy, assessment, billing or payment of any such
Impositions, and is hereby authorized by the Lessor to act for and on behalf of
the Lessor in any and all such respects and to prepare and file, on behalf of
the Lessor all tax returns and reports required to be filed by the Lessor (other
than federal income tax returns and documents related thereto) concerning the
Leased Property.  The Lessee's payment obligations under this Section 3(d) shall
survive  the termination of this Lease.  In the event that any withholding or
deduction from any payment to be made by the Lessee hereunder is required in
respect of any Imposition pursuant to any Legal Requirement, then the Lessee
will

            (x)  pay directly to the relevant authority the full amount 
                 required to be so withheld or deducted;

            (y)  promptly forward to the Lessor an official receipt or other
                 documentation satisfactory to the Lessor evidencing such 
                 payment to such authority; and

                                     -13-
<PAGE>
 
            (z)  pay to the Lessor such additional amount or amounts as is 
            necessary to ensure that the net amount actually received by
            the Lessor will equal the full amount the Lessor would have
            received had no such withholding or deduction been required.

     (e)    Unless otherwise expressly provided, all payments by the Lessee
pursuant to this Lease shall be made by the Lessee to the Lessor.  All such
payments required to be made to the Lessor shall be made not later than 11:00
a.m., New York, New York time, on the date due, in immediately available funds,
to such account as the Lessor shall specify from time to time by notice to the
Lessee.  Funds received after that time shall be deemed to have been received by
the Lessor on the next succeeding Business Day.  Whenever any payment to be made
shall otherwise be due on a day which is not a Business Day, except as otherwise
expressly provided herein, such payment shall be made on the next succeeding
Business Day and such extension shall be included in computing Rent, interest
and fees, if any, in connection with such payment.

     The Lessee is entering into the Agency Agreement with the Lessor pursuant

provisions of this Lease.

Section 7.  Maintenance and Replacement of the Leased Property; Operations.
            -------------------------------------------------------------- 

     (a)    The Lessee shall, and it shall require and cause any and all 
employees, contractors, subcontractors, agents, representatives, affiliates,
consultants and occupants at the Lessee's own cost and expense to (i) cause the
Leased Property to be maintained in good operating order, repair and condition,
in accordance with prudent industry practice and any applicable manufacturer's
manuals or warranties, subject to normal wear and tear, and will take all
action, and will make all changes and repairs, structural and non-structural,
foreseen and unforeseen, ordinary and extraordinary, which are required pursuant
to any Legal Requirement or Insurance Requirement at any time in effect to
assure full compliance therewith; and (ii) cause the Leased Property to continue
to have at all times the capacity and functional ability to perform, on a
continuing basis (subject to normal interruption in the ordinary course of
business for maintenance, inspection, service, repair and testing) and in
commercial operation, the functions for which it was designed as specified in
the Project Plan.

     (b)     The Lessee shall, and it shall require and cause any and all 
employees, contractors, subcontractors, agents, representatives, affiliates,
consultants and occupants at the Lessee's own cost and expense to, promptly
replace, or cause to be replaced, all Units of Leased Property or parts thereof
which may from time to time be incorporated or installed in or attached to the
Leased Property and which may from time to time become worn out, lost, stolen,
destroyed, seized, confiscated, damaged beyond repair, obsolete or permanently
rendered unfit for use for any reason whatsoever. All replacement Units of
Leased Property or parts thereof shall be free and clear of all Liens other than
Permitted Liens, shall be of a type customarily used in the industry at such
time for such purpose, shall be in as good operating condition as, and shall
have a utility and useful life at least equal to, the Units of Leased Property
or parts replaced (assuming such replaced Units of Leased Property or parts were
in the condition and repair required to be maintained by the terms hereof) and
shall have a value at least equal to the Units of Leased Property or parts
replaced (assuming such replaced Units of Leased Property or parts were in the
condition and repair required to be maintained by the terms hereof). Each Unit
of Leased Property or part thereof at any time removed shall remain the property
of (and title thereto shall remain in) Lessor or its Funding Sources, no matter
where located, until such time as such Unit of Leased Property or part shall be
replaced by a replacement Unit of Leased Property or part and that meets the
requirements for replacement Units of Leased Property or parts thereof specified
above. Immediately upon any replacement Unit of Leased Property or part thereof
becoming incorporated or installed in or attached to the Leased Property as
above provided, without further act or instrument, subject to Permitted Liens,
(i) title to the removed Unit of Leased Property or part thereof shall thereupon
vest in Lessee, free and clear of all rights of Lessor, and shall no longer be
deemed a Unit of Leased Property or part thereof hereunder; (ii) title to such
replacement Unit of Leased Property or part thereof shall thereupon vest in
Lessor; and (iii) such replacement Unit of Leased Property or part thereof shall
become subject to this Lease and be deemed a part of the Leased Property for all
purposes hereof to the same extent as the Unit of Leased Property or part
thereof originally incorporated or installed in or attached to the Leased
Property. Within ten Business Days of the end of each calendar quarter, an
Authorized Officer of the Lessee shall deliver to the Lessor a Repair and
Replacement Schedule certifying to Lessor's satisfaction (i) the nature of
repairs and replacements of Units of Leased Property or any component that has a
cost of at least $1,000,000 at the time of replacement or repair made during
such calendar quarter and the Units of Leased Property so repaired or replaced
and (ii) that the Project continues to have the capacity and functional ability
to perform on a continuing basis (subject to normal interruption in the ordinary

                                     -15-
<PAGE>
 
course of business for maintenance, inspection, service, repair and testing) and
in commercial operation, the functions for which it was designed as specified in
the Project Plan.

     (c)     Notwithstanding the provisions of Section 8 and the foregoing
provisions of this Section  7, the Lessee shall not remove, replace or alter any
Unit of Leased Property or affix or place any  accessory, equipment, part or
device on any Unit of Leased Property, if such removal, replacement,  alteration
or addition would impair the originally intended function or use of such Unit of
Leased  Property so as to materially reduce the value of any Unit of Leased
Property or the value of all of the  Leased Property taken as a whole.

     (d)     The Lessor shall not be required in any way to maintain, repair or
rebuild any Unit of Leased Property or any portion thereof and the Lessee waives
any right it may now or hereafter have to make any repairs at the expense of the
Lessor pursuant to any Legal Requirement at any time in effect or otherwise.

     (e)     The Lessee shall, and it shall require and cause any and all 
employees, contractors, subcontractors, agents, representatives, affiliates,
consultants and occupants at the Lessee's own cost and expense to, (i) comply in
all material respects with all applicable Environmental Laws with regard to the
Leased Property and (ii) use, employ, process, emit, generate, store, handle,
transport, dispose of and/or arrange for the disposal of, any and all hazardous
substances in, on or, directly or indirectly, related to or in connection with
the Leased Property or any part thereof in a manner consistent with prudent
industry practice and in compliance in all material respects with any applicable
Environmental Law, and in a manner which does not have a material adverse effect
on the use, occupancy, possession, value or condition of the Leased Property or
any Unit of Leased Property and does not give rise to continuing liability to
the Lessee or the Lessor. The Lessor and the Lessee hereby acknowledge and agree
that the Lessee's obligations hereunder with respect to Environmental Laws are
intended to bind the Lessee with respect to matters and conditions involving the
Leased Property or any part thereof. The Lessee, at its expense, will register
and re-register the Leased Property when necessary under applicable Legal
Requirements.

Section 8.  Removals Without Replacement.
            ---------------------------- 

     (a)    The Lessee may, unless a Default or an Event of Default shall 
occur and be continuing, upon at least five Business Days' prior written notice
to the Lessor, remove any Unit of Leased Property or part thereof, at its own
expense without replacing it; provided that such Unit of Leased Property or part
thereof is not a Major Component of the Project and is no longer necessary for
the performance of the Project on a continuing basis in commercial operation of
the functions for which the Project was designed as specified in the Project
Plan; and provided, further, that such removal and nonreplacement do not in any
material respect (i) diminish or impair the value, utility and useful life of
the Leased Property (subject to normal interruption in the ordinary course of
business for maintenance, inspection, service, repair and testing) or (ii)
result in the Leased Property becoming "limited use property" within the meaning
of Rev. Proc. 76-30, 1976-2 C.B. 647 (assuming, in each case, the Leased
Property was then of the value, utility and useful life required to be
maintained hereunder). Title to any such removed Unit of Leased Property or part
thereof shall vest in Lessee, free and clear of all rights of Lessor.

     (b)     If the Lessee determines that any Unit of Leased Property or part
thereof may be removed in accordance with Section 8(a) hereof, then the Lessee
shall give the Lessor at least 30 

                                     -16-
<PAGE>
 
days' notice of such determination and shall not remove any such Unit of Leased 
Property unless and until the Lessor has received written confirmation from the
Technical Consultant of the Lessee's determination that such Unit of Leased
Property is no longer necessary for the performance of the Project on a
continuing basis in commercial operation of the function for which the Project
was designed as specified in the Project Plan; provided, however, that the
Lessee may remove from this Lease Units of Leased Property determined to be no
longer necessary for the performance of the Project as aforesaid at any one time
having aggregate book values not exceeding $5,000,000 or at all times during the
term of this Lease having aggregate book values not exceeding $10,000,000. Any
Unit of Leased Property removed in accordance with Section 8(a) hereof, which
has a de minimis value, may be disposed of by the Lessee without any obligation
or liability to the Lessor. Except as provided in the immediately preceding
sentence, any Unit of Leased Property removed by the Lessee in accordance with
Section 8(a) hereof shall remain the property of the Lessor and shall be
delivered to the Lessor as soon as practicable.

Section 9.  Required and Optional Alterations; Title to Alterations.
            ------------------------------------------------------- 

     (a)     Except as otherwise provided in Section 14 hereof, Lessee at its 
own cost and expense, shall make (or cause to be made) all Alterations to the
Leased Property as may be required from time to time to meet in all material
respects all Legal Requirements (regardless of the Person upon whom such
requirements, by their terms, are nominally imposed), except to the extent being
contested in accordance with Section 10 hereof.

     (b)     Unless an Event of Default shall have occurred and be continuing,
Lessee, at its own cost and expense, may from time to time make, subject to
obtaining all necessary authorization, consents or approvals of any Governmental
Authority and consents of third parties, such Alterations to the Leased Property
that are not required pursuant to Section 9(a) as Lessee may deem desirable in
the proper conduct of its business, provided that (i) such Alternation shall not
diminish or impair in any material respect the value, utility or useful life of
the Leased Property (subject to normal interruption, in the ordinary course of
business for maintenance, inspection, service, repair and testing), (ii) such
Alteration shall not cause the Leased Property to constitute "limited use
property" within the meaning of Rev. Proc. 76-30, 1976-2 C.B. 647 and (iii) no
Alterations, taken together or separately, shall violate the provisions of Rev.
Proc. 75-21, 1975-1 C.B. 715 or 79-48, 1979-1 C.B. 529.

     (c)     Title to each Alteration shall without further act or instrument 
vest in the Lessor and be deemed to constitute a part of the Leased Property and
be subject to this Lease, provided that any such Alteration is required pursuant
to Section 9(a) hereof or is a Nonseverable Alteration. Title to all other
Alterations shall vest in the Lessee or such other Person as the Lessee shall
select, and the Lessee may finance the acquisition thereof in whatever manner it
elects, secured or unsecured, provided that such financing does not and will not
result in any Lien (other than Permitted Liens) on or with respect to the Leased
Property or any part thereof. Any such Alteration may be removed by the Lessee
or any Person having a Lien thereon, at its own cost and expense, at any time
prior to the Stated Lease Termination Date if the conditions set forth in
clauses (i) and (ii) of the proviso contained in Section 9(b) hereof are met and
such removal will not cause any of the Leased Property to be in violation of any
applicable Legal Requirement. Any such Alteration may also be removed at the
Stated Lease Termination Date upon not less than 90 days' prior written notice
to Lessor, so long as the Leased Property is restored substantially to its
condition (normal wear and tear excepted) prior to the making of such
Alteration, provided that such removal does not diminish or impair the 

                                     -17-
<PAGE>
 
required performance of the Leased Property (as specified in the Project Plan)
at such time; and provided, further, that any Severable Alterations that are not
removed from the Leased Property at the time of its surrender by the Lessee
shall become the property of the Lessor.

Section 10.  Compliance with Legal Requirements and Insurance Requirements:
             --------------------------------------------------------------
             Related Contracts.
             ----------------- 

     The Lessee at its expense, except as otherwise permitted by the last
sentence of this Section 10, will comply with all Legal Requirements applicable
to the Leased Property or any portion thereof or the ownership, construction,
operation, mortgaging, occupancy, possession, use, non-use or condition of the
Leased Property or any portion thereof, all Insurance Requirements, and all
instruments, contracts or agreements affecting title to or ownership of the
Leased Property or any portion thereof.  In addition, the Lessee, so long as no
Default or Event of Default has occurred and is continuing, is hereby authorized
by the Lessor to, and shall, fully and promptly keep, observe, perform and
satisfy on behalf of the Lessor any and all obligations, conditions, covenants
and restrictions of or on the Lessor or the Lessee under any and all Related
Contracts so that there will be no default thereunder and so that the other
parties thereunder shall be and remain at all times obliged to perform their
obligations thereunder, and the Lessee, to the extent within its control, shall
not permit to exist any condition, event or fact that could allow or serve as a
basis or justification for any such Person to avoid such performance.
Notwithstanding the first sentence of this Section 10, if (i) a test, challenge,
appeal or proceeding for review of any applicable Legal Requirement relating to
the use, operation or maintenance of the Leased Property shall be prosecuted in
good faith by Lessee or (ii) compliance with such Legal Requirement shall have
been excused or exempted by a nonconforming use permit, waiver, extension or
forbearance excusing or exempting Lessee from such Legal Requirement, Lessee
shall not be required to comply with such Legal Requirement so long as such
test, challenge, appeal, proceeding or noncompliance shall not involve any
material risk of (A) the sale, forfeiture or loss of, or imposition of any Lien
(other than a Permitted Lien or Lien being contested pursuant to Section 13) on,
any part of the Leased Property, title thereto or any interest therein or in
this Lease or impairment of the use or operation of any part of the Leased
Property as required by the Project Plan, (B) any material Claim not indemnified
against by Lessee against Lessor or the Leased Property or (C) the nonpayment of
Rent.

THE LEASED PROPERTY OR ANY EQUIPMENT OR FIXTURE OR OTHER ITEM CONSTITUTING A
PORTION THEREOF, WHERE PATENT OR LATENT, THE LESSOR SHALL NOT HAVE ANY
RESPONSIBILITY OR LIABILITY WITH RESPECT THERETO. THE PROVISIONS OF THIS SECTION
11 HAVE BEEN NEGOTIATED AND ARE INTENDED TO BE A COMPLETE EXCLUSION AND NEGATION
OF ANY AND ALL WARRANTIES, EXPRESS OR IMPLIED, BY THE LESSOR, WITH RESPECT TO
THE LEASED PROPERTY OR ANY EQUIPMENT, FIXTURE OR OTHER ITEM CONSTITUTING A
PORTION THEREOF, WHETHER ARISING PURSUANT TO THE UCC OR ANY OTHER LAW NOW OR
HEREAFTER IN EFFECT.

     (b)     The Lessor hereby assigns to the Lessee until the termination 
hereof or the occurrence of a Default or Event of Default hereunder any and all
warranties and indemnities of and claims against any manufacturers or Vendors
relating to any Unit of Leased Property (including any labor, equipment or parts
supplied therewith), and to the extent assignment of the same is prohibited or
precludes enforcement of any such warranty or undertaking, the Lessor hereby
subrogates the Lessee to its rights in respect thereof. The Lessor hereby
authorizes the Lessee, at the Lessee's expense, to assert any and all claims and
to prosecute any and all suits, actions and proceedings, in its own name or in
the name of the Lessor, in respect of any such warranty or undertaking and prior
to the termination hereof or the occurrence of a Default or Event of Default
hereunder, to retain the proceeds received, and after the termination of this
Lease or the occurrence of a Default or Event of Default to pay the same in the
form received (with any necessary endorsement) to the Lessor.

     (c)     The Lessee may use the Leased Property for any lawful purpose
consistent with the Development Plan and the Project Plan provided that the
value of the Leased  Property is not diminished by any such use other than as a
result of normal wear and tear in the ordinary course of business.  During the
term of this Lease, the Lessor covenants that unless a Default or an Event of
Default has occurred and is continuing, the Lessor will not, and will not permit
any party claiming by, through or under the Lessor to, interfere with the
peaceful and quiet possession and enjoyment of the Leased Property by the
Lessee; provided, however, that the Lessor and its successors, assigns,
representatives and agents may, upon reasonable notice to the Lessee enter upon
and examine the Leased Property or any part thereof at reasonable times, subject
to the provisions of Section 19 hereof.  Any failure by the Lessor to comply
with the foregoing provisions of this Section 11(c) shall not give the Lessee
any right to cancel or terminate this Lease, or to abate, reduce or make
reduction from or offset against any Rent, Additional Rent or other sum payable
under this Lease, or to fail to perform or observe any other covenant, agreement
or obligation hereunder.  The Lessee will not do or fail to do, or permit or
suffer to exist any act or thing, which action or thing or failure might impair
the value or usefulness of the Leased Property for the production and safe and
lawful handling of hydrocarbons and other functions contemplated by the design
of such Leased Property, ordinary wear and tear excepted.

Section 12.  Liens.

                                     -19-
<PAGE>
 
     (a)  The Lessee will not directly or indirectly create or permit to be
created or to remain, and will discharge promptly, at the Lessee's expense, any
Lien upon the Lease or the Leased Property except (i) any Lien being contested
as permitted by Section 13 hereof, or (ii) Permitted Liens.  The Lessor agrees
that the Lessee shall have during the term of this Lease the exclusive right (so
long as no Default or Event of Default has occurred and is continuing) to grant,
create or suffer to exist Permitted Liens in accordance with prudent industry
practices, provided that the fair market value or use of the Leased Property or
the applicable portion thereof is not materially lessened thereby.  The Lessor
agrees to execute such documents and take all other actions as shall be
reasonably necessary, and otherwise to cooperate with the Lessee in connection
with the matters described above, provided that all reasonable out-of-pocket
costs and expenses (including, without limitation, reasonable attorneys' fees
and expenses) incurred by the Lessor in connection therewith shall be borne by
the Lessee, and the Lessor shall not be required to execute any document which
would, in the opinion of the Lessor, materially adversely affect the value or
use of the Leased Property or otherwise materially adversely affect the
interests of the Lessor.

     (b)  The Lessee will not directly or indirectly sell, transfer, or
otherwise dispose of, or create or permit to be created or to remain, and will
discharge, any Lien of any nature whatsoever on, in or with respect to, its
interest in the Leased Tracts, except Permitted Liens, sales of hydrocarbons
produced from the Leased Tracts in the ordinary course of business and sales or
other dispositions of interests in the Leased Tracts; provided that the Lessee
shall retain at least 25% of the working interest and maintain a net revenue
interest at least equal to 70% of its working interest in the Leased Tracts. The
Lessee shall at all times remain the operator under any operating agreement
governing operation on the Leased Tracts except that a Co-Lessee permitted by
the terms of this Lease and qualified under all Legal Requirements may serve as
the operator.

     (c)  The Lessee acknowledges and agrees that this Lease is subsequent,
inferior, junior and subordinate in all respects to the Security Instruments as
defined in the Funding Agreement.  The Lessee will not contest or otherwise
challenge through litigation or by any other means the superior right, title and
interest of the Lessor and its Funding Sources as the secured parties under the
Security Instruments as defined in the Funding Agreement in and to the Leased
Property to the right, title and interest of the Lessee under this Lease.

Section 13.  Permitted Contests.
             ------------------ 

     After prior notice to the Lessor and provided there is no material risk of
sale, forfeiture or loss of any Unit of Leased Property, the Lessee may at its
expense contest any Imposition which it is required to pay hereunder, by
appropriate proceedings conducted in good faith and with due diligence, so long
as such proceedings are effective to prevent the collection of such Imposition
from the Lessor or any Funding Source (as it relates to any financing in
connection with the Funding Agreement) or against the Leased Property or any
portion thereof; provided, however, that the actions of the Lessee as authorized
by this Section 13 shall be subject to the express written consent of the Lessor
if such actions would subject the Lessor or any Funding Source to any liability
or sanction, criminal or otherwise, for failure to pay any such Imposition.  The
Lessee will pay, and save the Lessor and each such Funding Source harmless
against, all losses, Judgments, decrees and reasonable costs, including
attorneys' fees and expenses, in connection with any such contest and will,
promptly after the final determination of such contest, pay and discharge the
amounts which shall be imposed or determined to be payable therein, together
with all penalties, costs and expenses incurred in connection therewith.  The
Lessee shall prevent any foreclosure, judicial sale or 

                                    - 20 -
<PAGE>
 
forfeiture of the Leased Property or any portion thereof, or any interference
with or deductions from any Rent, Additional Rent or any other sum required to
be paid by the Lessee hereunder by reason of such nonpayment or nondischarge of
an Imposition. The Lessor shall cooperate with the Lessee in any contest and
shall allow the Lessee to conduct such contest (in the name of the Lessor, if
necessary) at the Lessee's sole cost and expense. The Lessee shall notify the
Lessor of each such proceeding within 10 days after the commencement thereof,
which notice shall describe such proceeding in reasonable detail.

Section 14.  Insurance, etc.
             -------------- 

     (a)  The Lessee will, at its own expense, purchase and maintain or cause to
be purchased and maintained throughout the term of this Lease insurance with
respect to its business and the Leased Property in accordance with the
requirements of Schedule 7 hereto.

     (b)  The Lessee shall bear all risk of loss, whether by casualty, theft,
taking or other confiscation, with respect to each Unit of Leased Property or
any portion thereof, at all times during the term of this Lease until possession
of any Unit of Leased Property has been accepted by the Lessor upon the return
of any such Unit of Leased Property to Lessor pursuant to Section 17 hereof.

     (c)  So long as no Default or Event of Default has occurred and is
continuing, any payments, whether constituting insurance proceeds, amounts paid
by any Governmental Authority or otherwise, received by the Lessee or the Lessor
upon the occurrence of any loss with respect to any Unit of Leased Property or
portion thereof (other than a Casualty Occurrence), whether as a result of
casualty, theft, taking or other confiscation, shall be applied in payment for
necessary repairs and replacement to the Leased Property in accordance with
Section 7 hereof or, to the extent the costs of such repairs and replacement
shall have been paid by the Lessee, to reimburse the Lessee.  The Lessee shall
be entitled to retain any excess funds remaining after necessary repairs and
replacements have been completed and all costs therefor paid in full.

     (d)  Upon a Casualty Occurrence, the Lessee shall give prompt notice
thereof to the Lessor and shall within 30 days of the date of such Casualty
Occurrence provide the Lessor with a plan acceptable to the Technical Consultant
setting forth how the Lessee shall replace, or cause to be replaced, at the
Lessee's own cost and expense, within 180 days after the date of such Casualty
Occurrence, any Unit of Leased Property the subject of a Casualty Occurrence;
provided, however, that the Lessee may remove from this Lease any Unit of Leased
Property the subject of a Casualty Occurrence if following such removal the
Lessee would be in compliance with Section 9(b) as if an Alteration were being
made. Within 60 days of the date of the Casualty Occurrence, the Lessee shall
have commenced repairs or replacements as specified in such a plan. After
completion of the repairs and replacements, the Lessee shall demonstrate to the
satisfaction of the Technical Consultant that operations and production from the
Project have been restored. This test must be satisfactorily completed within
180 days after the date of such Casualty Occurrence. All replacement Units of
Leased Property shall be free and clear of all Liens except Permitted Liens, and
shall be in as good operating condition as, and shall have a value and utility
at least equal to, the Unit of Leased Property replaced immediately prior to the
Casualty Occurrence to which such Unit of Leased Property was subject. For
purposes of this Lease (including without limitation this Section 14(d) and
Section 7), Fixed Charges paid, the Property Cost, and the Stipulated Loss Value
of the replacement Unit of Leased Property shall be deemed to equal the Fixed
Charges paid, the Property Cost and the Stipulated Loss Value of the Unit of
Leased Property replaced thereby. All Units of 

                                    - 21 -
<PAGE>
 
Leased Property at any time removed from this Lease pursuant to this Section
14(d) and Section 7 shall remain the property of the Lessor, no matter where
located, until such time as insurance proceeds have been received by the Lessor
at least equal to the Stipulated Loss Value of such Units of Leased Property or
such Units of Leased Property shall be replaced by Units of Leased Property
which have been incorporated or installed on or attached to Leased Property
located on the Project and which meet the requirements specified above.
Immediately upon any replacement Unit of Leased Property becoming incorporated
or installed on or attached to Leased Property located on the Project as
provided above, without further act, such replacement Unit of Leased Property
shall become subject to this Lease and be deemed part of the Leased Property for
all purposes hereof to the same extent as any other Units of Leased Property.
All amounts of insurance proceeds for property losses and all other proceeds
(whether resulting from damage or destruction or from condemnation, confiscation
or seizure) relating to the applicable Unit or Units of Leased Property shall be
deposited into the Restoration Account from any losses exceeding $5,000,000 per
occurrence and held and released as hereinafter provided. So long as no Default
or Event of Default shall have occurred and be continuing, and provided that the
Lessor shall have received a written application of the Lessee accompanied by a
certificate of an Authorized Officer of the Lessee showing in reasonable detail
the nature of any necessary repair, rebuilding and restoration, the actual cash
expenditures necessary for such repair, rebuilding and restoration, the expected
total expenditures required to complete such work and evidence that sufficient
funds are available to complete such work on a timely basis (such certificate to
be acceptable to the Lessor in all respects), then the amounts available in the
Restoration Account shall be released by the Lessor from time to time on each
Rent Payment Date during the period of repair, rebuilding and restoration in
payment therefor against presentation to the Lessor of a certificate executed by
an Authorized Officer of the Lessee to the effect that expenditures have been
made, or costs incurred, by or for the account of the Lessee or are reasonably
anticipated to be made during the immediately following Billing Period in a
specified amount for the purposes of making repairs, rebuilding and restoration
in the amounts specified, that no Default or Event of Default exists and all
conditions precedent herein provided relating to such withdrawal and payment
have been satisfied. Upon the occurrence of any Event of Default, the Lessor
shall be entitled to retain all amounts in the Restoration Account for
application to the obligations of the Lessee hereunder.

Section 15.  Termination; Surrender of Leased Property.
             ----------------------------------------- 

     (a)  In addition to any other rights provided to Lessor hereunder, Lessor
shall have the right to terminate this Lease upon delivery to Lessee of a notice
that Lessor has determined to exercise its rights to purchase the Leased Tracts
under that certain lease agreement, dated as of even date herewith, between
Lessor and Lessee relating to Garden Banks 388 Lease No. 2.  Following the
delivery of such notice the Term shall be deemed to have ended upon the date of
exercise of the foregoing option.

     (b)  Unless all right, title and interest in the Leased Property shall have
been or is being transferred to Lessee or unless Lessee shall have paid
Stipulated Loss Value with respect to the Leased Property, in each case,
pursuant to this Lease, Lessee shall, upon the expiration of the Term or the
earlier termination of the Lease as provided herein, return the Leased Property
to Lessor or to any transferee or assignee of Lessor and deliver therewith a
complete set, current as of the date of such return, of all customary operating
manuals, logs and plans and specifications necessary or appropriate for the
proper operation and maintenance of the Leased Property, together with all
maintenance and repair reports prepared during the Term in respect of such
Leased Property.  At the 

                                    - 22 -
<PAGE>
 
time of such return, the Leased Property (i) shall be, at a minimum, in the
condition required by Section 7, (ii) shall be in good working order and shall
include all Alterations made by Lessee to the extent such Alterations become the
property of Lessor pursuant to Section 9, and (iii) shall not be "limited use
property" within the meaning of Rev. Proc. 76-30, 1976-2 C.B. 647. Lessee shall
assign to Lessor all warranties, registrations, licenses and permits, to the
extent permitted under Applicable Law, required to be possessed by Lessee or
Lessor with respect to the Leased Property.

Section 16.  Lessee's Renewal Option.
             ----------------------- 

     Upon expiration of the Basic Term, if no Event of Default, Casualty
Occurrence or Constructive Total Loss shall have occurred and be continuing,
Lessee may, upon at least 60 days' irrevocable prior written notice to Lessor,
elect to renew the Lease upon the same terms and conditions for a period of five
years (the "Fair Market Renewal Term"); provided that Rent during such Fair
Market Renewal Term shall be determined by reference to a Fixed Charge Balance
which reflects the Fair Market Rental Value as determined at the commencement of
such Fair Market Renewal Term.

     return the Leased Property promptly to Lessor in the manner and condition
     required by, and otherwise in accordance with the provisions of, this Lease

     Lessor shall not be liable for the reimbursement of Lessee for any costs
     and expenses incurred by Lessee in connection therewith, and (B) take

     of damage to property caused by such taking or otherwise, except damage
     caused by Lessor's negligence or willful misconduct;

          (iii) Whether or not any action has been taken under clause (i) or
     (ii) above, Lessor may sell the Leased Property or any part thereof at

     Lessee or of any Person claiming by, through or under Lessee and without
     any duty to account to Lessee with respect to such sale or any proceeds
     with respect thereto (except to the extent required by clause (v) or (vi)

     event Lessee's obligation to pay Rent hereunder for periods commencing
     after the date of such sale shall be terminated (except to the extent that

     to any Person claiming by, through or under Lessee with respect to such
     action or inaction or for any proceeds with respect to such action or
     inaction, except that Lessee's obligation to pay Rent for periods
     commencing after Lessee shall have been deprived of use of the Leased
     Property pursuant to this clause (iv) shall be reduced by the net proceeds,
     if any, received by Lessor from leasing the Leased Property to any Person
     other than Lessee for the same periods or any portion thereof;

          (v)   Lessor may, whether or not Lessor shall have exercised or shall

     Rent Payment Date specified in such notice plus whichever of the following
     amounts Lessor, in its sole discretion, shall specify in such notice

          specified in such notice;

                (B)  if Lessor takes possession of the Leased Property, an
          amount equal to the excess of (1) the present value as of the Rent

          Rent until the end of the Basic Term or the Fair Market Renewal Term,
          as the case may be, discounted semiannually at a rate of 10% per
          annum, over (2) the present value as of such payment date of the Fair
          Market Rental Value of the Leased Property until the end of the Basic
          Term or the Fair Market Renewal Term, as the case may be, discounted

     unpaid Rent due through such Rent Payment Date, plus the amount of any
     deficiency between Stipulated Loss Value, computed as of such Rent Payment
     Date, and the net proceeds of such sale, together with interest at the 
     Post-Default Rate on the amount of such Rent and such deficiency from the

may be exercised from time to time and as often and in such order as may be

other right, power or remedy.  No delay or omission by Lessor in the exercise of
any right, power or remedy shall restrict Lessor from exercising the same or any
other right, power or remedy thereafter nor be construed to be a waiver of any

Lessor's sole discretion, may be necessary or appropriate therefor and, upon the
occurrence and during the continuance of a Triggering Event, may enter upon the
Leased Property for such purpose and take all such action thereon as, at the
Lessor's sole discretion, may be necessary or appropriate therefor.  No such
entry shall be deemed an eviction of the Lessee.  All sums so paid by the Lessor

demand as Additional Rent.

Section 21.  Participation by Co-Lessees or Sublessees.

this Lease to its Funding Sources to secure the obligation of the Lessor under
the Funding Agreement.

     (b)  The Lessor and the Lessee may from time to time, so long as no Default
or Event of Default shall have occurred and be continuing, enter into
documentation amending this Lease and, as necessary, the Operative Documents, to

certain obligations of the Lessee and the attendant reduction in the obligations
of the Lessee hereunder, subject in every case to the prior written approval of
the Lessor acting in its sole and unfettered discretion in approving said Co-
Lessee and the documentation amending this Lease and the Operative Documents, it
being understood that the Lessor may for any reason whatsoever elect not to
grant such approval, in which case this Lease shall not be amended.

     (c)  The Lessee may from time to time with the written consent of Lessor,
so long as no Default or Event of Default shall have occurred and be continuing,
enter into a sublease and such other documentation as may be necessary with one

by the Lessee in connection with the subletting of the Leased Property (i) shall
expressly state that such sublease is subject and subordinate to the terms of
this Lease and the Security Instruments and (ii) shall not provide for a
sublease term ending after the then current Stated Lease Termination Date.  Upon
request of the Lessor, the Lessee will furnish to the Lessor copies of all
subleases and related documentation entered into by the Lessee from time to
time.  No sublease permitted by the terms hereof will reduce in any respect the
obligations of the 

                                    - 28 -

Lessee hereunder, it being the intent of the Lessee and the Lessor that the

Property at the end of the Term is at least 10% of the useful life of the Leased
Property determined as of the Delivery Date, and that the Fair Value of such
Unit of Leased Property at the end of the Term determined as of the Delivery
Date is at least 10% of the Leased Property Cost.

  (c) Insurance Endorsements - Any insurance carried in accordance herewith
shall, except as hereinafter permitted, provide or be endorsed to provide that:

      (i) the Lessor and the Agent on behalf of the Lenders, as their interests
  may appear, shall be included as additional insureds or named as loss payees
  except as respects coverages required by Paragraphs (a)(ii), (a)(iv),
  (b)(ii)(1) and (b)(ii)(3), with the understanding that any obligation imposed
  upon the insured (including, without limitation, the liability to pay
  premiums) under any policy required by this Schedule shall be the obligation
  of the Lessee (or, if appropriate, Special General Partner and its Affiliates)
  and not that of the Lessor, the Agent or any Lender;

      (ii) losses, if any, under any property insurance with respect to the
  Project shall be adjusted as provided in Paragraph (d), and insurance proceeds
  with respect to losses, if any, in excess of $5,000,000 per occurrence
  (including such amount) in respect of the Project shall be paid into the
  Restoration Account, and insurance proceeds with respect to other losses in
  respect of the Facility shall be payable to the Lessee;

      (iii) except with respect to the coverage required by Paragraphs (a)(i),
  (a)(ii), (a)(iv), (a)(vi), (b)(i), (b)(ii)(1) and (b)(ii)(3), a cross-
  liability and severability of interest endorsement providing that to the
  extent the policy is written to cover more than one insured, all terms,
  conditions, insuring agreements and endorsements, with the exception of limits
  of liability and deductibles, shall operate in the same manner as if there
  were a separate policy covering each insured;

      (iv) the insurer thereunder waives all rights of subrogation against the
  Lessor, the Agent or the Lenders;

      (v) such insurance shall be primary without right of contribution of any
  other insurance carried by or on behalf of the Lessor, the Agent or the
  Lenders with respect to its or their interests in the Project;

      (vi) if such insurance is cancelled for any reason whatsoever (including,
  without limitation, nonpayment of premium) or any material change is made in
  the coverage that affects the interests of the Lessor, the Agent or the
  Lenders, such cancellation or change shall not be effective as to the Lessor,
  the Agent and the Lenders for 10 days for nonpayment of premiums and otherwise
  for 45 days, in both cases after receipt by the Lessor and the Agent (at the
  address provided pursuant to Section 22 of the Lease) of written notice sent
  by certified mail from such insurer of such cancellation or change; and

      (vii) Any insurance carried in accordance with clauses (a)(ii)(y),
  (a)(iii)(y) and (a)(v)(y) of this Schedule shall contain essentially the same
  endorsements as are set forth in clauses (c)(i), (c)(iv), (c)(v) and (c)(vi)
  in favor of the Lessee rather than the Lessor, the Agent and the Lenders.
<PAGE>
 
  (d) Adjustment of Property Losses - The loss, if any, under any property
insurance covering the Project required to be carried by this Schedule shall be
adjusted with the insurance companies or otherwise collected, including, without
limitation, the filing of appropriate proceedings, by the Lessee in consultation
with the Lessor and the Agent.

  (e) Reinstatement of Limits - The Lessee shall, or shall cause its insurance
broker to, notify promptly the Lessor and the Agent at any time when the limits
of the excess commercial liability insurance required by Paragraphs (a)(v) or
(b)(ii)(4) shall have been reduced, either by reason of payments of, or the
establishment of reserves for the ultimate payment of, claims which have been
asserted during the term of such insurance, by an aggregate amount in excess of
$10,000,000.  At such time, the Lessee shall, if so requested by the Lessor, use
its best efforts to reinstate such insurance so as to comply with the requisite
limits prescribed herein.

  (f) Upon request, the Lessee will furnish the Lessor and the Agent copies of
all insurance policies, binders and cover notes or other evidence of such
insurance relating to the Project, as the case may be.

  (g) Additional Insurance by the Lenders or the Lessee - Nothing in this
Schedule shall prohibit the Lessor, the Agent, any Lender or the Lessee or any
of its Partners, as their respective interests may appear, from maintaining for
its own account, at the expense of the Person purchasing such insurance,
additional insurance on or with respect to the Project, or any part thereof,
with coverage exceeding that otherwise required under this Schedule, unless such
insurance would conflict with or limit the insurance otherwise required under
this Schedule.

Section 2.  Lease of Leased Property.
            ------------------------ 

        Subject to the terms and conditions of this Lease, on the Lease
Commencement Date, and subsequently upon the Delivery Date of any additional
Units of Leased Property, Lessor agrees to lease to Lessee, and Lessee agrees to
lease from Lessor, the Leased Property as identified from time to time in the
Leased Property Inventory Schedule, for the Basic Term, and subject to the
exercise by Lessee of its rights provided in Section 16 hereof, for the Fair
Market Renewal Term.

Section 3.  Payments.
            -------- 

        (a) The Lessee shall pay to the Lessor on the Rent Payment Date for
each Billing Period the amount of Rent and the Quarterly Expense Charge, if any,
due for such Billing Period.  At least three (3) Business Days before the Rent
Payment Date for each Billing Period, the Lessor shall deliver to the Lessee a
Lessor Payment Notice, in the form of Schedule 2A, reflecting the Rent and the
Quarterly Expense Charge, if any, due for such Billing Period.  If the Quarterly
Rent Charge as of any Rent Payment Date differs from the rate applied on the
immediately preceding Rent Payment Date, the Lessor shall deliver to the Lessee
an amended Rent Schedule which shall reflect the effect of such Quarterly Rent
Charge on all remaining payments of Rent up to and including the expiration date
of the current Term.  The Lessee shall complete the Leased Property Inventory
Schedule for such Billing Period and deliver the same to the Lessor on the Rent
Payment Date and shall pay to the Lessor on the Rent Payment Date the amount of
Rent and the Quarterly Expense Charge, if any, specified by Lessor in its notice
to the Lessee, unless Lessor shall have notified Lessee that a different amount
of Rent and the Quarterly Expense Charge, if any, is due, in which case Lessee
shall pay such corrected amount of Rent within two (2) Business Days of the date
of the updated notice.  Failure to deliver such written notice or inaccuracies
in such notice will not excuse the Lessee from payment of the amount of Rent and
the Quarterly Expense Charge, if any, due; provided that if Lessee makes timely
payment to Lessor in accordance with such notice and the payment amount
submitted by Lessor to Lessee is determined to be inaccurate, the incorrect
payment shall not constitute an Event of Default, as long as the correct amount
is paid in full within two (2) Business Days of the date of an updated notice.

        (b) In addition to the Rent and Quarterly Expense Charge, if any, the
Lessee will also pay, from time to time, upon demand of the Lessor, as
additional rent ("Additional Rent") to the Lessor the following (but without
duplication of any amounts included in the calculation of Rent or otherwise paid
by the Lessee):

            (i) All out-of-pocket costs and expenses reasonably incurred by the
                Lessor in connection with the preparation, negotiation,
                execution, delivery, performance and administration of this
                Lease and the other Operative Documents (including, without
                limitation, reasonable attorneys' fees and expenses). The Lessee
                also shall pay all amounts payable by the Lessor with respect to
                the transactions contemplated hereby and by the Funding
                Agreement and the other Operative Documents in respect of the
                following; (A) fees and expenses of the Lessor, including,
                without limitation, reasonable 

                                     -11-
<PAGE>
 
                attorneys' fees and expenses; (B) all other amounts, including,
                without limitation, fees, indemnities, expenses and compensation
                in respect of increased costs, capital adequacy or breakage of
                any kind or description payable under the Funding Agreement or
                any other Operative Document; (C) out-of-pocket costs and
                expenses incurred by the Lessor after the date of this Lease
                (including, without limitation, reasonable attorneys' fees and
                expenses and other expenses and disbursements reasonably
                incurred) associated with (x) negotiating and entering into, or
                the giving or withholding of, any future amendments,
                supplements, waivers or consents with respect to this Lease; (y)
                any Casualty Occurrence or termination of this Lease; and (z)
                any Event of Default and the enforcement of the rights or
                remedies of the Lessor under this Lease and the other Operative
                Documents.

           (ii) All other amounts that the Lessee agrees herein to pay other
                than Rent and amounts described in clause (i) above.

        (c) This Lease is a completely net lease, and Rent, Additional Rent
and all other sums payable by the Lessee hereunder shall be paid without notice
except as otherwise expressly provided herein, and the Lessee shall not be
entitled to any abatement, reduction, setoff, counterclaim, defense or deduction
with respect to any Rent, Additional Rent or other sum payable hereunder.  The
obligations of the Lessee to pay Rent, Additional Rent and all other sums
payable hereunder shall not be affected by any circumstance whatsoever,
including without limitation: (a) any damage to or destruction of the Leased
Property or any part thereof by any cause whatsoever (including, without
limitation, fire, casualty or act of God or enemy or any other force majeure
event); (ii) any condemnation, including, without limitation, a temporary
condemnation of the Leased Property or any portion thereof; (iii) any
prohibition, limitation, restriction or prevention of the Lessee's use,
occupancy or enjoyment of the Leased Property or any part thereof by any Person;
(iv) any matter affecting title to the Leased Property or any portion thereof;
(v) any eviction of the Lessee from, or loss of possession by the Lessee of, the
Leased Property or any portion thereof, by reason of title paramount or
otherwise; (vi) any default by the Lessor hereunder or under any other
agreement; (vii) the invalidity or unenforceability of any provision hereof or
the impossibility or illegality of performance by the Lessor or the Lessee or
both; (viii) any action of any federal, state or local governmental authority;
or (ix) any other cause or occurrence whatsoever, whether similar or dissimilar
to the foregoing.  The Lessee shall remain obliged under this Lease in
accordance with its terms and shall not take any action to terminate, rescind or
avoid this Lease, notwithstanding any bankruptcy, insolvency, reorganization,
liquidation, dissolution or other proceeding affecting the Lessor or any action
with respect to this Lease which may be taken by any trustee, receiver or
liquidator or by any court.  The Lessee waives all rights to terminate or
surrender this Lease, or to any abatement or deferment of Rent, Additional Rent
or other sums payable hereunder.  The Lessee hereby waives any and all rights
now or hereafter conferred by law or otherwise to modify or to avoid strict
compliance with its obligations under this Lease.  All payments made to the
Lessor hereunder as required hereby shall be final and irrevocable, absent
manifest error, and the Lessee shall not seek to recover any such payment or any
part thereof for any reason whatsoever, absent manifest error.  All covenants
and agreements of Lessee herein shall be performed at its cost, expense and risk
unless expressly otherwise stated.  Nothing herein shall be construed as a
guaranty by the Lessee of any residual value in the Leased Property nor to
prevent the Lessee from asserting in any legal action any mandatory
counterclaim.

                                     -12-

        (d) The Lessee agrees that it will promptly pay all Impositions imposed
upon or levied or assessed against or relating to (i) this Lease or any future
amendment, supplement, waiver or consent requested by Lessee with respect
thereto, or the execution, delivery or performance of any thereof or the
issuance, acquisition or subsequent transfer thereto, (ii) the Leased Property
or any portion thereof, (iii) the manufacture, financing, construction,
purchase, acceptance, possession, rejections, ownership, delivery, nondelivery,
use, operation, leasing, subleasing, condition, maintenance, repair, sale,
control, return, transfer, abandonment, redelivery or other disposition of the
Leased Property, (iv) the Lessor (and its predecessors and its and their
successors and permitted assigns and their respective partners, officers,
directors, employees and agents) in connection with the transactions
contemplated by this Lease and the Master Lease (including all obligations of
Lessor in respect of payments or otherwise hereunder or thereunder) or imposed
or levied upon, assessed against or measured by any Rent or other sum payable
hereunder, and will furnish to the Lessor upon request copies of official
receipts or other proof evidencing such payments; provided, however, that the
                                                  --------  -------
Lessee shall not be obligated to pay (A) any sales Taxes or other Impositions to
the extent paid by the Lessor as part of the Property Cost of any Unit of Leased
Property and financed under the Funding Agreement, (B) any Impositions which are
based upon or measured by the Lessor's net income, or which are in substitution
for, or relieve the Lessor from, any actual Imposition based upon or measured by
the Lessor's net income (excluding, however, Impositions imposed with respect to
the payment, receipt or accrual of any indemnity payment under this Lease), or
(C) Impositions characterized under local law as franchise Taxes (excluding,
however, any value-added, license, property or similar Imposition). The Lessee
further agrees that, subject to its rights under Section 13 hereof, it will, at
its expense, do all things required to be done by the Lessor in connection with
the levy, assessment, billing or payment of any such Impositions, and is hereby
authorized by the Lessor to act for and on behalf of the Lessor in any and all
such respects and to prepare and file, on behalf of the Lessor all tax returns
and reports required to be filed by the Lessor (other than federal income tax
returns and documents related thereto) concerning the Leased Property. The
Lessee's payment obligations under this Section 3(d) shall survive the
termination of this Lease. In the event that any withholding or deduction from
any payment to be made by the Lessee hereunder is required in respect of any
Imposition pursuant to any Legal Requirement, then the Lessee will

            (x) pay directly to the relevant authority the full amount required
            to be so withheld or deducted;

            (y) promptly forward to the Lessor an official receipt or other
            documentation satisfactory to the Lessor evidencing such payment to
            such authority; and

            (z) pay to the Lessor such additional amount or amounts as is
            necessary to ensure that the net amount actually received by the
            Lessor will equal the full amount the Lessor would have received had
            no such withholding or deduction been required.

        (e) Unless otherwise expressly provided, all payments by the Lessee
pursuant to this Lease shall be made by the Lessee to the Lessor.  All such
payments required to be made to the Lessor shall be made not later than 11:00
a.m., New York, New York time, on the date due, in immediately available funds,
to such account as the Lessor shall specify from time to time by notice to the
Lessee.  Funds received after that time shall be deemed to have been received by
the Lessor on the next succeeding Business Day.  Whenever any payment to be made
shall otherwise be due on a day which is not a Business Day, except as otherwise
expressly provided herein, such payment 

                                     -13-
<PAGE>
 
shall be made on the next succeeding Business Day and such extension shall be
included in computing Rent, interest and fees, if any, in connection with such
payment.

Section 4.  Agency Agreement.

        The Lessee is entering into the Agency Agreement with the Lessor
pursuant to which the Lessee will act as the construction agent for the Lessor

Units of Leased Property shall be subject to the terms and conditions of this
Lease. Certain of the Units of Leased Property shall be purchased, manufactured
or assembled pursuant to Related Contracts entered into by the Lessee pursuant
to the Agency Agreement. After a funding pursuant to the Funding Agreement of an
initial payment under any Related Contract, the rights of the Lessee held for
the benefit of the Lessor under such Related Contract shall become subject to
the provisions of this Lease.

Section 5.  Leased Property Records.
            ----------------------- 

        The Lessee shall maintain, on a current basis, books of proper record

        Except as otherwise specified in Sections 7(b), 8(a) (in respect of
removals) and Section 9(c) (in respect of certain Alterations), the Lessor or
its Funding Sources shall own 100% of the legal and beneficial interest in each
Unit of Leased Property, and all accessories, equipment, parts and devices
affixed or placed on any Unit of Leased Property from time to time by the Lessee
if required to achieve Completion shall be and become part of such Unit of
Leased Property for the purposes of this Lease and shall be property of the
Lessor or its Funding Sources subject to the terms of this Lease.

Section 7.  Maintenance and Replacement of the Leased Property; Operations.
            -------------------------------------------------------------- 

        (a) The Lessee shall, and it shall require and cause any and all
employees, contractors, subcontractors, agents, representatives, affiliates,
consultants and occupants at the Lessee's own cost and expense to (i) cause the
Leased Property to be maintained in good operating order, repair and condition,
in accordance with prudent industry practice and any applicable manufacturer's
manuals or warranties, subject to normal wear and tear, and will take all
action, and will make all changes and repairs, structural and  non-structural,
foreseen and unforeseen, ordinary and extraordinary, which are required pursuant
to  any Legal Requirement or Insurance Requirement at any time in effect to
assure full compliance  therewith; and (ii) cause the Leased Property to
continue to have at all times the capacity and  functional ability to perform,
on a continuing basis (subject to normal interruption in the ordinary  course of
business for maintenance, inspection, service, repair and 

                                     -14-
<PAGE>
 
testing) and in commercial operation, the functions for which it was designed as
specified in the Project Plan.

        (b) The Lessee shall, and it shall require and cause any and all
employees, contractors,  subcontractors, agents, representatives, affiliates,
consultants and occupants at the Lessee's own cost  and expense to, promptly
replace, or cause to be replaced, all Units of Leased Property or parts  thereof
which may from time to time be incorporated or installed in or attached to the
Leased  Property and which may from time to time become worn out, lost, stolen,
destroyed, seized,  confiscated, damaged beyond repair, obsolete or permanently
rendered unfit for use for any reason  whatsoever.  All replacement Units of
Leased Property or parts thereof shall be free and clear of all  Liens other
than Permitted Liens, shall be of a type customarily used in the industry at
such time for  such purpose, shall be in as good operating condition as, and
shall have a utility and useful life at  least equal to, the Units of Leased
Property or parts replaced (assuming such replaced Units of  Leased Property or
parts were in the condition and repair required to be maintained by the terms
hereof) and shall have a value at least equal to the Units of Leased Property or
parts replaced  (assuming such replaced Units of Leased Property or parts were
in the condition and repair required  to be maintained by the terms hereof).
Each Unit of Leased Property or part thereof at any time removed shall remain
the property of (and title thereto shall remain in) Lessor or its Funding
Sources, no matter where located, until such time as such Unit of Leased
Property or part shall be replaced by a replacement Unit of Leased Property or
part and that meets the requirements for replacement Units of Leased Property or
parts thereof specified above.  Immediately upon any replacement Unit of Leased
Property or part thereof becoming incorporated or installed in or attached to
the Leased Property as above provided, without further act or instrument,
subject to Permitted Liens, (i) title to the removed Unit of Leased Property or
part thereof shall thereupon vest in Lessee, free and clear of all rights of
Lessor, and shall no longer be deemed a Unit of Leased Property or part thereof
hereunder; (ii) title to such replacement Unit of Leased Property or part
thereof shall thereupon vest in Lessor; and (iii) such replacement Unit of
Leased Property or part thereof shall become subject to this Lease and be deemed
a part of the Leased Property for all purposes hereof to the same extent as the
Unit of Leased Property or part thereof originally incorporated or installed in
or attached to the Leased Property.  Within ten Business Days of the end of each
calendar quarter,  an Authorized Officer of the Lessee shall deliver to the
Lessor a Repair and Replacement Schedule  certifying to Lessor's satisfaction
(i) the nature of repairs and replacements of Units of Leased  Property or any
component that has a cost of at least $1,000,000 at the time of replacement or
repair  made during such calendar quarter and the Units of Leased Property so
repaired or replaced and (ii)  that the Project continues to have the capacity
and functional ability to perform on a continuing basis  (subject to normal
interruption in the ordinary course of business for maintenance, inspection,
service, repair and testing) and in commercial operation, the functions for
which it was designed as  specified in the Project Plan.

        (c) Notwithstanding the provisions of Section 8 and the foregoing
provisions of this Section  7, the Lessee shall not remove, replace or alter any
Unit of Leased Property or affix or place any  accessory, equipment, part or
device on any Unit of Leased Property, if such removal, replacement,  alteration
or addition would impair the originally intended function or use of such Unit of
Leased  Property so as to materially reduce the value of any Unit of Leased
Property or the value of all of the  Leased Property taken as a whole.

        (d) The Lessor shall not be required in any way to maintain, repair or
rebuild any Unit of Leased Property or any portion thereof and the Lessee waives
any right it may now or hereafter

                                     -15-
<PAGE>
 
have to make any repairs at the expense of the Lessor pursuant to any Legal
Requirement at any time in effect or otherwise.

        (e) The Lessee shall, and it shall require and cause any and all
employees, contractors, subcontractors, agents, representatives, affiliates,
consultants and occupants at the Lessee's own cost and expense to, (i) comply in
all material respects with all applicable Environmental Laws with regard to the
Leased Property and (ii) use, employ, process, emit, generate, store, handle,
transport, dispose of and/or arrange for the disposal of, any and all hazardous
substances in, on or, directly or indirectly, related to or in connection with
the Leased Property or any part thereof in a manner consistent with prudent
industry practice and in compliance in all material respects with any applicable
Environmental Law, and in a manner which does not have a material adverse effect
on the use, occupancy, possession, value or condition of the Leased Property or
any Unit of Leased Property and does not give rise to continuing liability to
the Lessee or the Lessor.  The Lessor and the Lessee hereby acknowledge and
agree that the Lessee's obligations hereunder with respect to Environmental Laws
are intended to bind the Lessee with respect to matters and conditions involving
the Leased Property or any part thereof.  The Lessee, at its expense, will
register and re-register the Leased Property when necessary under applicable
Legal Requirements.

Section 8.  Removals Without Replacement.
            ---------------------------- 

        (a) The Lessee may, unless a Default or an Event of Default shall occur
and be continuing, upon at least five Business Days' prior written notice to the
Lessor, remove any Unit of Leased Property or part thereof, at its own expense
without replacing it; provided that such Unit of Leased Property or part thereof
is not a Major Component of the Project and is no longer necessary for the
performance of the Project on a continuing basis in commercial operation of the
functions for which the Project was designed as specified in the Project Plan;
and provided, further, that such removal and nonreplacement do not in any
material respect (i) diminish or impair the value, utility and useful life of
the Leased Property (subject to normal interruption in the ordinary course of
business for maintenance, inspection, service, repair and testing) or (ii)
result in the Leased Property becoming "limited use property" within the meaning
of Rev. Proc. 76-30, 1976-2 C.B. 647 (assuming, in each case, the Leased
Property was then of the value, utility and useful life required to be
maintained hereunder). Title to any such removed Unit of Leased Property or part
thereof shall vest in Lessee, free and clear of all rights of Lessor.

        (b) If the Lessee determines that any Unit of Leased Property or part
thereof may be removed in accordance with Section 8(a) hereof, then the Lessee
shall give the Lessor at least 30 days' notice of such determination and shall
not remove any such Unit of Leased Property unless and until the Lessor has
received written confirmation from the Technical Consultant of the Lessee's
determination that such Unit of Leased Property is no longer necessary for the
performance of the Project on a continuing basis in commercial operation of the
function for which the Project was designed as specified in the Project Plan;
provided, however, that the Lessee may remove from this Lease Units of Leased
Property determined to be no longer necessary for the performance of the Project
as aforesaid at any one time having aggregate book values not exceeding
$5,000,000 or at all times during the term of this Lease having aggregate book
values not exceeding $10,000,000.  Any Unit of Leased Property removed in
accordance with Section 8(a) hereof, which has a de minimis value, may be
disposed of by the Lessee without any obligation or liability to the Lessor.
Except as provided in the immediately preceding sentence, any Unit of Leased
Property removed 

                                     -16-
<PAGE>
 
by the Lessee in accordance with Section 8(a) hereof shall remain the property
of the Lessor and shall be delivered to the Lessor as soon as practicable.

Section 9.  Required and Optional Alterations; Title to Alterations.
            ------------------------------------------------------- 

        (a) Except as otherwise provided in Section 14 hereof, Lessee at its
own cost and expense, shall make (or cause to be made) all Alterations to the
Leased Property as may be required from time to time to meet in all material
respects all Legal Requirements (regardless of the Person upon whom such
requirements, by their terms, are nominally imposed), except to the extent being
contested in accordance with Section 10 hereof.

        (b) Unless an Event of Default shall have occurred and be continuing,
Lessee, at its own cost and expense, may from time to time make, subject to
obtaining all necessary authorization, consents or approvals of any Governmental
Authority and consents of third parties, such Alterations to the Leased Property
that are not required pursuant to Section 9(a) as Lessee may deem desirable in
the proper conduct of its business, provided that (i) such Alternation shall not
diminish or impair in any material respect the value, utility or useful life of
the Leased Property (subject to normal interruption, in the ordinary course of
business for maintenance, inspection, service, repair and testing), (ii) such
Alteration shall not cause the Leased Property to constitute "limited use
property" within the meaning of Rev. Proc. 76-30, 1976-2 C.B. 647 and (iii) no
Alterations, taken together or separately, shall violate the provisions of Rev.
Proc. 75-21, 1975-1 C.B. 715 or 79-48, 1979-1 C.B. 529.

        (c) Title to each Alteration shall without further act or instrument
vest in the Lessor and be deemed to constitute a part of the Leased Property and
be subject to this Lease, provided that any such Alteration is required pursuant
to Section 9(a) hereof or is a Nonseverable Alteration.  Title to all other
Alterations shall vest in the Lessee or such other Person as the Lessee shall
select, and the Lessee may finance the acquisition thereof in whatever manner it
elects, secured or unsecured, provided that such financing does not and will not
result in any Lien (other than Permitted Liens) on or with respect to the Leased
Property or any part thereof.  Any such Alteration may be removed by the Lessee
or any Person having a Lien thereon, at its own cost and expense, at any time
prior to the Stated Lease Termination Date if the conditions set forth in
clauses (i) and (ii) of the proviso contained in Section 9(b) hereof are met and
such removal will not cause any of the Leased Property to be in violation of any
applicable Legal Requirement. Any such Alteration may also be removed at the
Stated Lease Termination Date upon not less than 90 days' prior written notice
to Lessor, so long as the Leased Property is restored substantially to its
condition (normal wear and tear excepted) prior to the making of such
Alteration, provided that such removal does not diminish or impair the required
performance of the Leased Property (as specified in the Project Plan) at such
time; and provided, further, that any Severable Alterations that are not removed
from the Leased Property at the time of its surrender by the Lessee shall become
the property of the Lessor.


Section 10.  Compliance with Legal Requirements and Insurance Requirements:
             --------------------------------------------------------------
             Related Contracts.
             ----------------- 

        The Lessee at its expense, except as otherwise permitted by the last
sentence of this Section 10, will comply with all Legal Requirements applicable
to the Leased Property or any portion thereof or the ownership, construction,
operation, mortgaging, occupancy, possession, use, non-use or condition of the
Leased Property or any portion thereof, all Insurance Requirements, and 

                                     -17-
<PAGE>
 
all instruments, contracts or agreements affecting title to or ownership of the
Leased Property or any portion thereof. In addition, the Lessee, so long as no
Default or Event of Default has occurred and is continuing, is hereby authorized
by the Lessor to, and shall, fully and promptly keep, observe, perform and
satisfy on behalf of the Lessor any and all obligations, conditions, covenants
and restrictions of or on the Lessor or the Lessee under any and all Related
Contracts so that there will be no default thereunder and so that the other
parties thereunder shall be and remain at all times obliged to perform their
obligations thereunder, and the Lessee, to the extent within its control, shall
not permit to exist any condition, event or fact that could allow or serve as a
basis or justification for any such Person to avoid such performance.
Notwithstanding the first sentence of this Section 10, if (i) a test, challenge,
appeal or proceeding for review of any applicable Legal Requirement relating to
the use, operation or maintenance of the Leased Property shall be prosecuted in
good faith by Lessee or (ii) compliance with such Legal Requirement shall have
been excused or exempted by a nonconforming use permit, waiver, extension or
forbearance excusing or exempting Lessee from such Legal Requirement, Lessee
shall not be required to comply with such Legal Requirement so long as such
test, challenge, appeal, proceeding or noncompliance shall not involve any
material risk of (A) the sale, forfeiture or loss of, or imposition of any Lien
(other than a Permitted Lien or Lien being contested pursuant to Section 13) on,
any part of the Leased Property, title thereto or any interest therein or in
this Lease or impairment of the use or operation of any part of the Leased
Property as required by the Project Plan, (B) any material Claim not indemnified
against by Lessee against Lessor or the Leased Property or (C) the nonpayment of
Rent.

        (a) THE LEASED PROPERTY IS LEASED AS IS, WHERE IS, AND WITH ALL FAULTS
AND IN THE CONDITION THEREOF AND SUBJECT TO THE RIGHTS OF ANY PARTIES IN
POSSESSION THEREOF, THE STATE OF THE TITLE THERETO, AND THE RIGHTS OF OWNERSHIP
THEREIN, IN EACH CASE AS IN EXISTENCE WHEN THE SAME FIRST BECOMES SUBJECT TO
THIS LEASE, WITHOUT REPRESENTATIONS AND WARRANTIES OF ANY KIND AS TO TITLE BY
THE  LESSOR, OR ANY PERSON ACTING ON BEHALF OF ANY OF THEM.  THE  LESSEE
ACKNOWLEDGES AND AGREES THAT THE LESSOR IS NOT A MANUFACTURER OF, OR VENDOR OF,
OR MERCHANT WITH RESPECT TO, ANY OF SUCH EQUIPMENT OR ANY PROPERTY OF SUCH KIND
AND HAS NOT MADE NOR IS MAKING ANY WARRANTY, EXPRESS OR IMPLIED, RELATING TO THE
LEASED PROPERTY, INCLUDING WITHOUT LIMITATION, WITH RESPECT TO MERCHANTABILITY,

DEFECT OR DEFICIENCY OF ANY NATURE IN THE LEASED PROPERTY OR ANY EQUIPMENT OR
FIXTURE OR OTHER ITEM CONSTITUTING A PORTION THEREOF, WHERE PATENT OR LATENT,

EQUIPMENT, FIXTURE OR OTHER ITEM CONSTITUTING A PORTION THEREOF, WHETHER ARISING
PURSUANT TO THE UCC OR ANY OTHER LAW NOW OR HEREAFTER IN EFFECT.

        (b) The Lessor hereby assigns to the Lessee until the termination
hereof or the occurrence of a Default or Event of Default hereunder any and all
warranties and indemnities of and claims against any manufacturers or Vendors
relating to any Unit of Leased Property (including any labor, equipment or parts
supplied therewith), and to the extent assignment of the same is prohibited or
precludes enforcement of any such warranty or undertaking, the Lessor hereby
subrogates the Lessee to its rights in respect thereof.  The Lessor hereby
authorizes the Lessee, at the Lessee's expense, to assert any and all claims and
to prosecute any and all suits, actions and proceedings, in its own name or in
the name of the Lessor, in respect of any such warranty or undertaking and prior
to the termination hereof or the occurrence of a Default or Event of Default
hereunder, to retain the proceeds received, and after the termination of this
Lease or the occurrence of a Default or Event of Default to pay the same in the
form received (with any necessary endorsement) to the Lessor.

        (c) The Lessee may use the Leased Property for any lawful purpose
consistent with the Development Plan and the Project Plan provided that the
value of the Leased  Property is not diminished by any such use other than as a
result of normal wear and tear in the ordinary course of business.  During the
term of this Lease, the Lessor covenants that unless a Default or an Event of
Default has occurred and is continuing, the Lessor will not, and will not permit
any party claiming by, through or under the Lessor to, interfere with the
peaceful and quiet possession and enjoyment of the Leased Property by the
Lessee; provided, however, that the Lessor and its successors, assigns,
representatives and agents may, upon reasonable notice to the Lessee enter upon
and examine the Leased Property or any part thereof at reasonable times, subject
to the provisions of Section 19 hereof.  Any failure by the Lessor to comply
with the foregoing provisions of this Section 11(c) shall not give the Lessee
any right to cancel or terminate this Lease, or to abate, reduce or make
reduction from or offset against any Rent, Additional Rent or other sum payable
under this Lease, or to fail to perform or observe any other covenant, agreement
or obligation hereunder.  The Lessee will not do or fail to do, or permit or
suffer to exist any act or thing, which action or thing or failure might impair
the value or usefulness of the Leased Property for the production and safe and
lawful handling of hydrocarbons and other functions contemplated by the design
of such Leased Property, ordinary wear and tear excepted.

Section 12.  Liens.
             ----- 

        (a)  The Lessee will not directly or indirectly create or permit to be
created or to remain, and will discharge promptly, at the Lessee's expense, any
Lien upon the Lease or the Leased Property except (i) any Lien being contested
as permitted by Section 13 hereof, or (ii) Permitted Liens.  The Lessor agrees
that the Lessee shall have during the term of this Lease the exclusive right (so
long as no Default or Event of Default has occurred and is continuing) to grant,
create or suffer to exist Permitted Liens in accordance with prudent industry
practices, provided that the fair market value or use of the Leased Property or
the applicable portion thereof is not materially lessened thereby.  The Lessor
agrees to execute such documents and take all other actions as shall be
reasonably necessary, and otherwise to cooperate with the Lessee in connection
with the matters described above, provided that all reasonable out-of-pocket
costs and expenses (including, without limitation, reasonable attorneys' fees
and expenses) incurred by the Lessor in connection therewith 

                                     -19-
<PAGE>
 
shall be borne by the Lessee, and the Lessor shall not be required to execute
any document which would, in the opinion of the Lessor, materially adversely
affect the value or use of the Leased Property or otherwise materially adversely
affect the interests of the Lessor.

        (b)  The Lessee will not directly or indirectly sell, transfer, or
otherwise dispose of, or create or permit to be created or to remain, and will
discharge, any Lien of any nature whatsoever on, in or with respect to, its
interest in the Leased Tracts, except  Permitted Liens, sales of hydrocarbons
produced from the Leased Tracts in the ordinary course of business and sales or
other dispositions of interests in the Leased Tracts; provided that the Lessee
shall retain at least 25% of the working interest and maintain a net revenue
interest at least equal to 70% of its working interest in the Leased Tracts.
The Lessee shall at all times remain the operator under any operating agreement
governing operation on the Leased Tracts except that a Co-Lessee permitted by
the terms of this Lease and qualified under all Legal Requirements may serve as
the operator.

        (c)  The Lessee acknowledges and agrees that this Lease is subsequent,
inferior, junior and subordinate in all respects to the Security Instruments as
defined in the Funding Agreement.  The Lessee will not contest or otherwise
challenge through litigation or by any other means the superior right, title and
interest of the Lessor and its Funding Sources as the secured parties under the
Security Instruments as defined in the Funding Agreement in and to the Leased
Property to the right, title and interest of the Lessee under this Lease.

Section 13.  Permitted Contests.
             ------------------ 

        After prior notice to the Lessor and provided there is no material
risk of sale, forfeiture or loss of any Unit of Leased Property, the Lessee may
at its expense contest any Imposition which it is required to pay hereunder, by
appropriate proceedings conducted in good faith and with due diligence, so long
as such proceedings are effective to prevent the collection of such Imposition
from the Lessor or any Funding Source (as it relates to any financing in
connection with the Funding Agreement) or against the Leased Property or any
portion thereof; provided, however, that the actions of the Lessee as authorized
by this Section 13 shall be subject to the express written consent of the Lessor
if such actions would subject the Lessor or any Funding Source to any liability
or sanction, criminal or otherwise, for failure to pay any such Imposition.  The
Lessee will pay, and save the Lessor and each such Funding Source harmless
against, all losses, Judgments, decrees and reasonable costs, including
attorneys' fees and expenses, in connection with any such contest and will,
promptly after the final determination of such contest, pay and discharge the
amounts which shall be imposed or determined to be payable therein, together
with all penalties, costs and expenses incurred in connection therewith. The
Lessee shall prevent any foreclosure, judicial sale or forfeiture of the Leased
Property or any portion thereof, or any interference with or deductions from any
Rent, Additional Rent or any other sum required to be paid by the Lessee
hereunder by reason of such nonpayment or nondischarge of an Imposition. The
Lessor shall cooperate with the Lessee in any contest and shall allow the Lessee
to conduct such contest (in the name of the Lessor, if necessary) at the
Lessee's sole cost and expense. The Lessee shall notify the Lessor of each such
proceeding within 10 days after the commencement thereof, which notice shall
describe such proceeding in reasonable detail.

Section 14.  Insurance, etc.
             -------------- 

        (a) The Lessee will, at its own expense, purchase and maintain or cause
to be purchased and maintained throughout the term of this Lease insurance with
respect to its business and the Leased Property in accordance with the
requirements of Schedule 7 hereto.

        (b) The Lessee shall bear all risk of loss, whether by casualty, theft,
taking or other confiscation, with respect to each Unit of Leased Property or
any portion thereof, at all times during the term of this Lease until possession
of any Unit of Leased Property has been accepted by the Lessor upon the return
of any such Unit of Leased Property to Lessor pursuant to Section 17 hereof.

        (c)  So long as no Default or Event of Default has occurred and is
continuing, any payments, whether constituting insurance proceeds, amounts paid
by any Governmental Authority or otherwise, received by the Lessee or the Lessor
upon the occurrence of any loss with respect to any Unit of Leased Property or
portion thereof (other than a Casualty Occurrence), whether as a result of
casualty, theft, taking or other confiscation, shall be applied in payment for
necessary repairs and replacement to the Leased Property in accordance with
Section 7 hereof or, to the extent the costs of such repairs and replacement
shall have been paid by the Lessee, to reimburse the Lessee.  The Lessee shall
be entitled to retain any excess funds remaining after necessary repairs and
replacements have been completed and all costs therefor paid in full.

        (d)  Upon a Casualty Occurrence, the Lessee shall give prompt notice
thereof to the Lessor and shall within 30 days of the date of such Casualty
Occurrence provide the Lessor with a plan acceptable to the Technical Consultant
setting forth how the Lessee shall replace, or cause to be replaced, at the
Lessee's own cost and expense, within 180 days after the date of such Casualty
Occurrence, any Unit of Leased Property the subject of a Casualty Occurrence;
provided, however, that the Lessee may remove from this Lease any Unit of Leased
Property the subject of a Casualty Occurrence if following such removal the
Lessee would be in compliance with Section 9(b) as if an Alteration were being
made.  Within 60 days of the date of the Casualty Occurrence, the Lessee shall
have commenced repairs or replacements as specified in such a plan.  After
completion of the repairs and replacements, the Lessee shall demonstrate  to the
satisfaction of the Technical Consultant that operations and production from the
Project have been restored. This test must be satisfactorily completed within
180 days after the date of such Casualty Occurrence. All replacement Units of
Leased Property shall be free and clear of all Liens except Permitted Liens, and
shall be in as good operating condition as, and shall have a value and utility
at least equal to, the Unit of Leased Property replaced immediately prior to the
Casualty Occurrence to which such Unit of Leased Property was subject. For
purposes of this Lease (including without limitation this Section 14(d) and
Section 7), Fixed Charges paid, the Property Cost, and the Stipulated Loss Value
of the replacement Unit of Leased Property shall be deemed to equal the Fixed
Charges paid, the Property Cost and the Stipulated Loss Value of the Unit of
Leased Property replaced thereby. All Units of Leased Property at any time
removed from this Lease pursuant to this Section 14(d) and Section 7 shall
remain the property of the Lessor, no matter where located, until such time as
insurance proceeds have been received by the Lessor at least equal to the
Stipulated Loss Value of such Units of Leased Property or such Units of Leased
Property shall be replaced by Units of Leased Property which have been
incorporated or installed on or attached to Leased Property located on the
Project and which meet the requirements specified above. Immediately upon any
replacement Unit of Leased Property becoming incorporated or installed on or
attached to Leased Property located on the Project as provided above, without
further act, such replacement Unit of Leased Property shall 

                                     -21-
<PAGE>
 
become subject to this Lease and be deemed part of the Leased Property for all
purposes hereof to the same extent as any other Units of Leased Property. All
amounts of insurance proceeds for property losses and all other proceeds
(whether resulting from damage or destruction or from condemnation, confiscation
or seizure) relating to the applicable Unit or Units of Leased Property shall be
deposited into the Restoration Account from any losses exceeding $5,000,000 per
occurrence and held and released as hereinafter provided. So long as no Default
or Event of Default shall have occurred and be continuing, and provided that the
Lessor shall have received a written application of the Lessee accompanied by a
certificate of an Authorized Officer of the Lessee showing in reasonable detail
the nature of any necessary repair, rebuilding and restoration, the actual cash
expenditures necessary for such repair, rebuilding and restoration, the expected
total expenditures required to complete such work and evidence that sufficient
funds are available to complete such work on a timely basis (such certificate to
be acceptable to the Lessor in all respects), then the amounts available in the
Restoration Account shall be released by the Lessor from time to time on each
Rent Payment Date during the period of repair, rebuilding and restoration in
payment therefor against presentation to the Lessor of a certificate executed by
an Authorized Officer of the Lessee to the effect that expenditures have been
made, or costs incurred, by or for the account of the Lessee or are reasonably
anticipated to be made during the immediately following Billing Period in a
specified amount for the purposes of making repairs, rebuilding and restoration
in the amounts specified, that no Default or Event of Default exists and all
conditions precedent herein provided relating to such withdrawal and payment
have been satisfied. Upon the occurrence of any Event of Default, the Lessor
shall be entitled to retain all amounts in the Restoration Account for
application to the obligations of the Lessee hereunder.

Section 15.  Surrender of Leased Property.
             ---------------------------- 

        Unless all right, title and interest in the Leased Property shall have
been or is being transferred to Lessee or unless Lessee shall have paid
Stipulated Loss Value with respect to the Leased Property, in each case,
pursuant to this Lease, Lessee shall, upon the expiration of the Term or the
earlier termination of the Lease as provided herein, return the Leased Property
to Lessor or to any transferee or assignee of Lessor and deliver therewith a
complete set, current as of the date of such return, of all customary operating
manuals, logs and plans and specifications necessary or appropriate for the
proper operation and maintenance of the Leased Property, together with all
maintenance and repair reports prepared during the Term in respect of such
Leased Property. At the time of such return, the Leased Property (i) shall be,
at a minimum, in the condition required by Section 7, (ii) shall be in good
working order and shall include all Alterations made by Lessee to the extent
such Alterations become the property of Lessor pursuant to Section 9, and (iii)
shall not be "limited use property" within the meaning of Rev. Proc. 76-30, 1976
2 C.B. 647. Lessee shall assign to Lessor all warranties, registrations,
licenses and permits, to the extent permitted under Applicable Law, required to
be possessed by Lessee or Lessor with respect to the Leased Property.

        Upon the expiration of the Basic Term, and if no Event of Default,

continuing, Lessee may, upon at least 30 and not more than 60 days' irrevocable
prior written notice to Lessor, elect to renew the Lease upon the same terms and
conditions for a period of five years (the "Fair Market Renewal Term"); provided

        shall have the right, upon at least 30 and not more than 60 days'
        irrevocable prior written notice to Lessor, to purchase from Lessor (the
        "Lessee Purchase Option") all of the Leased Property upon the expiration
        of the Basic Term for an amount equal to $46,170,000, such amount to be
        adjusted to account for any Leased Property added to the Lease after the
        Lease Commencement Date.

             (ii) Lessee shall pay the purchase price to Lessor on the date
        fixed for such purchase and Lessee shall simultaneously pay to Lessor
        all Rent and all other amounts, if any, due or accrued through such
        purchase date, whereupon Lessor shall transfer its right, tile and
        interest to the Leased Property to Lessee free and clear of all Liens
        (except Permitted Liens) but otherwise without representation or
        warranty, expressed or implied, and the Term shall end.

        (c)  Lessor Purchase Option.
             ---------------------- 

             (i) (x) Upon expiration of the Basic Term in the event that either
        (A) Lessee has not provided notice of its intention to exercise the
        Lessee Renewal Option in accordance with Section 16(a) or (B) that
        Lessee has not provided notice of its intention to exercise the Lessee
        Purchase Option in accordance with Section 16(b), (y) upon the expiry of
        the Fair Market Renewal Term, or (z) upon the termination of the Lease
        or the repossession of Leased Property by Lessor following an Event of
        Default, Lessor shall have the right to purchase (the "Lessor Purchase
        Option") in accordance with the Facilities Agreements, Lessee's interest
        in the Garden Banks Block 388 Unit as identified in Schedules F, G and H
        hereto at a purchase price equal to the fair market value of such
        interest as of the date of such purchase, as determined in accordance
        with accepted industry standards by an independent appraiser having a
        national reputation and experience in appraising the value of oil and
        gas reserves and offshore production facilities, chosen by mutual
        agreement between Lessor and Lessee. The parties hereby agree to use
        their best efforts to obtain such appraisal as soon as is reasonably
        practical after the occurrence of either of the events in clauses (x),
        (y) or (z) above.

            (ii) Lessor shall pay the amount due to Lessee on the date fixed for

            (x) ENSERCH Corporation shall cease to own, directly or indirectly,
                the majority of the outstanding shares of the Lessee.

        (b) If an Event of Default shall have occurred and be continuing, Lessor
may, at its option, by notice to Lessee declare this Lease to be in default, and
at any time thereafter Lessor may exercise one or more of the following as
Lessor in its sole discretion shall elect:

            (i) Lessor may, by notice to Lessee, rescind or terminate this Lease
        and all rights of Lessee hereunder to the use and possession of the
        Leased Property;

           (ii) Lessor may (A) demand that Lessee, and thereupon Lessee shall,
        return the Leased Property promptly to Lessor in the manner and
        condition required by, and otherwise in accordance with the provisions
        of, this Lease as if the Leased Property were being returned at the end
        of the Term and Lessor shall not be liable for the reimbursement of
        Lessee for any costs and expenses incurred by Lessee in connection
        therewith, and (B) take immediate possession of (to the exclusion of
        Lessee) the Leased Property, by summary proceedings or otherwise, all
        without liability of Lessor to Lessee (or to any Person claiming by,
        through or under Lessee) for or by reason of such entry or taking of
        possession, whether for the restoration of damage to property caused by
        such taking or otherwise, except damage caused by Lessor's negligence or
        willful misconduct;

          (iii) Whether or not any action has been taken under clause (i) or
        (ii) above, Lessor may sell the Leased Property or any part thereof at
        public or private sale, as Lessor may determine, with or without notice
        to Lessee, advertisement or publication, free and clear of any rights of
        Lessee or of any Person claiming by, through or under Lessee and without
        any duty to account to Lessee with respect to such sale or any proceeds
        with respect thereto (except to the extent required by clause (v) or
        (vi) below if Lessor shall elect to exercise its 

                                     -25-
<PAGE>
 
rights thereunder), in which event Lessee's obligation to pay Rent hereunder 
for periods commencing after the date of such sale shall be terminated (except 
to the extent that Rent is to be included in computations under clause (v) or 
(vi) below if Lessor shall elect to exercise its rights thereunder);


     (iv)  Lessor may hold, keep idle, use, operate or lease to others all
or any part of the Leased Property as Lessor in its sole discretion may
determine, free and clear of any rights of Lessee (or any Person claiming by,
through or under Lessee) and without any duty to account to Lessee or to any
Person claiming by, through or under Lessee with respect to such action or
inaction or for any proceeds with respect to such action or inaction, except
that Lessee's obligation to pay Rent for periods commencing after Lessee shall
have been deprived of use of the Leased Property pursuant to this clause (iv)
shall be reduced by the net proceeds, if any, received by Lessor from leasing
the Leased Property to any Person other than Lessee for the same periods or any
portion thereof;

     (v)   Lessor may, whether or not Lessor shall have exercised or shall
thereafter at any time exercise its rights under clause (ii), (iii) or (iv)
above, demand, by written notice to Lessee specifying a payment date which shall
be a Rent Payment Date not earlier than 10 days after the date of such notice,
that Lessee pay to Lessor, and Lessee shall pay to Lessor, on the Rent Payment
Date specified in such notice, as liquidated damages for loss of a bargain and
not as a penalty (in lieu of Rent due after the Rent Payment Date specified in
such notice), any unpaid Rent due through the Rent Payment Date specified in
such notice plus whichever of the following amounts Lessor, in its sole
discretion, shall specify in such notice (together with interest on such amount
at the Post-Default Rate from the Rent Payment Date specified in such notice to
the date of actual payment);

           (A)  if Lessor takes possession of the Leased Property, an amount 
     equal to the excess, if  any, of such Stipulated Loss Value over the Fair 
     Value of Leased Property as of the Rent Payment Date specified in such 
     notice;

           (B)  if Lessor takes possession of the Leased Property, an amount
     equal to the excess of (1) the present value as of the Rent Payment Date
     specified in such notice of all remaining installments of Rent until the
     end of the Basic Term or the Fair Market Renewal Term, as the case may be,
     discounted semiannually at a rate of 20% per annum, over (2) the present
     value as of such payment date of the Fair Market Rental Value of the Leased
     Property until the end of the Basic Term or the Fair Market Renewal Term,
     as the case may be, discounted semiannually at a rate of 20% per annum; or

           (C)  an amount equal to the Stipulated Loss Value, computed as of the
     Rent Payment Date specified in such notice and upon payment thereof and all
     other amounts then due by Lessee hereunder, Lessor shall transfer all of
     its right, title and interest in the Leased Property to Lessee, free and
     clear of all Liens (except Permitted Liens), but otherwise without
     representations or warranties, expressed or implied;

     (vi)  If Lessor shall have sold all the Leased Property pursuant to
clause (iii) above, Lessor, in lieu of exercising its rights under clause (v)
above with respect to the 

                                     -26-
<PAGE>
 
     Leased Property, may (but shall not be obligated to) demand that Lessee pay
     to Lessor and Lessee shall pay to Lessor on the date of such sale, as
     liquidated damages for loss of a bargain and not as a penalty (in lieu of
     Rent due for periods commencing after the next Rent Payment Date following
     the date of such sale), any unpaid Rent due through such Rent Payment Date,
     plus the amount of any deficiency between Stipulated Loss Value, computed
     as of such Rent Payment Date, and the net proceeds of such sale, together
     with interest at the Post-Default Rate on the amount of such Rent and such
     deficiency from the date of such sale until the date of actual payment; or

          (vii)   Lessor may exercise any other right or remedy that may be
     available to it under applicable law or proceed by appropriate court 
     action to enforce the terms hereof or to recover damages for the breach 
     hereof.

     (c)  In addition to the foregoing, Lessee shall be and remain liable
for paying or reimbursing Lessor for (i) any and all Rent and other amounts due
and payable under this Lease prior to any such Event of Default, and (ii) all
costs and expenses incurred by Lessor (including reasonable fees and expenses of
counsel) in connection with any exercise of its remedies provided in Section
17(b).

     (d)  No rescission or termination of this Lease, in whole or in part,
or repossession of the Leased Property or exercise of any remedy under Section
17(b) shall, except as specifically provided therein, relieve Lessee of any of
its liabilities and obligations hereunder.  In addition, Lessee shall be liable,
except as otherwise provided above, for any and all unpaid Rent due hereunder
before, after or during the exercise of any of the foregoing remedies, including
all reasonable legal fees and other costs and expenses incurred by Lessor by
reason of the occurrence of any Event of Default or the exercise of Lessor's
remedies with respect thereto and including all costs and expenses incurred in
connection with the return of the Leased Property in the manner and condition
required by, and otherwise in accordance with the provisions of, this Lease as
if the Leased Property were being returned at the end of the Term. At any sale
of the Leased Property or any part thereof pursuant to Section 17(b), Lessor may
bid for and purchase such property.

     (e)  To the extent permitted by, and subject to the mandatory Section 
17(b) or otherwise available to Lessor shall be cumulative and shall be in
addition to every other right, power and remedy, and each and every right, power
and remedy may be exercised from time to time and as often and in such order as
may be deemed expedient by Lessor, and the exercise or the beginning of exercise
of any such right, power or remedy shall not exhaust the same or be construed to
be a waiver of the right to exercise at the same time or thereafter the same or
any other right, power or remedy. No delay or omission by Lessor in the exercise
of any right, power or remedy shall restrict Lessor from exercising the same or
any other right, power or remedy thereafter nor be construed to be a waiver of
any Event of Default or to be an acquiescence therein. No express or implied
waiver by Lessor of any Event of Default shall in any way be, or be construed to
be, a waiver of any future or subsequent Event of Default.

Section 19.  Inspection; Right to Enter Premises of the Lessee.
             ------------------------------------------------- 

        The Lessor, or its respective authorized representatives may (but
without any obligation to do so) (i) enter upon the Leased Property or any
premises of the Lessee at reasonable times upon reasonable advance notice in
order to inspect the Leased Property (subject to the availability thereof for
inspection) and to inspect, audit and make copies of all documents and
instruments in the possession of the Lessee that are reasonably necessary or
appropriate for the Lessor or such authorized representatives to determine the
truth and accuracy of any schedule, annex, exhibit or representation delivered
or made hereunder, or compliance by the Lessee with any of the agreements herein
contained, and (ii) discuss the condition and performance of the Leased Property
with the responsible officers of the Lessor.  Such inspections of the Leased
Property located in the Gulf of Mexico shall be subject to Lessee's reasonable
discretion as operator to bar access to the Units of Leased Property for safety
reasons.  Such inspections of Leased Property located in the Gulf of Mexico
shall be performed under Lessee's supervision as operator.

Section 20.  Right to Perform the Lessee's Covenants.
             --------------------------------------- 

        Subject to Section 13 hereof, if the Lessee shall fail to make any
payment or perform any act required to be made or performed by it hereunder, the
Lessor, upon notice to or demand upon the Lessee but without waiving or
releasing any obligation or default, may (but shall be under no obligation to)
at any time thereafter make such payment or perform such act (other than
entering upon the Leased Property) for the account and at the expense of the
Lessee as, at the Lessor's sole discretion, may be necessary or appropriate
therefor and, upon the occurrence and during the continuance of a Triggering
Event, may enter upon the Leased Property for such purpose and take all such
action thereon as, at the Lessor's sole discretion, may be necessary or
appropriate therefor.  No such entry shall be deemed an eviction of the Lessee.
All sums so paid by the Lessor and all costs and expenses (including, without
limitation, reasonable attorneys' fees and expenses so incurred) shall be paid
by the Lessee to the Lessor on demand as Additional Rent.

Section 21.  Participation by Co-Lessees or Sublessees.
             ----------------------------------------- 

        (a)  Except as otherwise permitted in this Section 21 or in the
Declaration, the Lessee may not assign its rights or obligations under this
Lease without the prior consent of the Lessor.  The Lessor has granted a Lien on
this Lease to its Funding Sources to secure the obligation of the Lessor under
the Funding Agreement.

        (b)  The Lessor and the Lessee may from time to time, so long as no
Default or Event of Default shall have occurred and be continuing, enter into
documentation amending this Lease and, as necessary, the Operative Documents, to
evidence the undertaking of a Person (a "Co-Lessee") to be responsible for
certain obligations of the Lessee and the attendant reduction in the obligations
of the Lessee hereunder, subject in every case to the prior written approval of
the Lessor acting in its sole and unfettered discretion in approving said Co-
Lessee and the documentation amending this Lease and the Operative Documents, it
being understood that the Lessor may for any reason whatsoever elect not to
grant such approval, in which case this Lease shall not be amended.

        (c)  The Lessee may from time to time with the written consent of
Lessor, so long as no Default or Event of Default shall have occurred and be
continuing, enter into a sublease and such other documentation as may be
necessary with one or more Persons (each a "Sublessee").  In any 

                                     -28-
<PAGE>
 
event, any documentation executed by the Lessee in connection with the
subletting of the Leased Property (i) shall expressly state that such sublease
is subject and subordinate to the terms of this Lease and the Security
Instruments and (ii) shall not provide for a sublease term ending after the then
current Stated Lease Termination Date. Upon request of the Lessor, the Lessee
will furnish to the Lessor copies of all subleases and related documentation
entered into by the Lessee from time to time. No sublease permitted by the terms
hereof will reduce in any respect the obligations of the Lessee hereunder, it
being the intent of the Lessee and the Lessor that the Lessee be and remain
directly and primarily liable as a principal for its obligations hereunder. Any
sublease made otherwise than as expressly permitted by this Section 21(c) shall
be null and void and of no force or effect.

 may appear, shall be included as additional insureds or named as loss payees
 except as respects coverages required by Paragraphs (a)(ii), (a)(iv),
 (b)(ii)(1) and (b)(ii)(3), with the understanding that any obligation imposed
 upon the insured (including, without limitation, the liability to pay premiums)
 under any policy required by this Schedule shall be the obligation of the
 Lessee (or, if appropriate, Special General Partner and its Affiliates) and not
 that of the Lessor, the Agent or any Lender;

    (ii) losses, if any, under any property insurance with respect to the 
 Project shall be adjusted as provided in Paragraph (d), and insurance proceeds
 with respect to losses, if any, in excess of $5,000,000 per occurrence
 (including such amount) in respect of the Project shall be paid into the
 Restoration Account, and insurance proceeds with respect to other losses in
 respect of the Facility shall be payable to the Lessee;

   (iii) except with respect to the coverage required by Paragraphs (a)(i),
 (a)(ii), (a)(iv), (a)(vi), (b)(i), (b)(ii)(1) and (b)(ii)(3), a cross-liability
 and severability of interest endorsement providing that to the extent the
 policy is written to cover more than one insured, all terms, conditions,
 insuring agreements and endorsements, with the exception of limits of liability
 and deductibles, shall operate in the same manner as if there were a separate
 policy covering each insured;

 other insurance carried by or on behalf of the Lessor, the Agent or the Lenders
 with respect to its or their interests in the Project;

 without limitation, nonpayment of premium) or any material change is made in

 Lenders, such cancellation or change shall not be effective as to the Lessor,
 the Agent and the Lenders for 10 days for nonpayment of premiums and otherwise
 for 45 days, in both cases after receipt by the Lessor and the Agent (at the
 address provided pursuant to Section 22 of the Lease) of written notice sent by
 certified mail from such insurer of such cancellation or change; and

   (vii) Any insurance carried in accordance with clauses (a)(ii)(y),
 (a)(iii)(y) and (a)(v)(y) of this Schedule shall contain essentially the same
 endorsements as are set forth in clauses (c)(i), (c)(iv), (c)(v) and (c)(vi) in
 favor of the Lessee rather than the Lessor, the Agent and the Lenders.
<PAGE>
 
   (d) Adjustment of Property Losses - The loss, if any, under any property
 insurance covering the Project required to be carried by this Schedule shall be
 adjusted with the insurance companies or otherwise collected, including,
 without limitation, the filing of appropriate proceedings, by the Lessee in
 consultation with the Lessor and the Agent.

   (e)  Reinstatement of Limits - The Lessee shall, or shall cause its insurance
 broker to, notify promptly the Lessor and the Agent at any time when the limits
 of the excess commercial liability insurance required by Paragraphs (a)(v) or
 (b)(ii)(4) shall have been reduced, either by reason of payments of, or the
 establishment of reserves for the ultimate payment of, claims which have been
 asserted during the term of such insurance, by an aggregate amount in excess of
 $10,000,000.  At such time, the Lessee shall, if so requested by the Lessor,
 use its best efforts to reinstate such insurance so as to comply with the
 requisite limits prescribed herein.

   (f) Upon request, the Lessee will furnish the Lessor and the Agent copies of
 all insurance policies, binders and cover notes or other evidence of such
 insurance relating to the Project, as the case may be.

   (g) Additional Insurance by the Lenders or the Lessee - Nothing in this
 Schedule shall prohibit the Lessor, the Agent, any Lender or the Lessee or any
 of its Partners, as their respective interests may appear, from maintaining for
 its own account, at the expense of the Person purchasing such insurance,
 additional insurance on or with respect to the Project, or any part thereof,
 with coverage exceeding that otherwise required under this Schedule, unless
 such insurance would conflict with or limit the insurance otherwise required
 under this Schedule.

     is commercially feasible, that the useful life of such Equipment at the end
     of the Term will be at least 20% of the useful life of the Equipment
     determined as of the Delivery Date, and that the Fair Value of such Unit of
     Equipment at the end of the Term determined as of the Delivery Date will be
     approximately 20% or greater of the Equipment Cost (determined (i) without
     including in such fair value any increase or decrease for inflation or
     deflation during the Term and (ii) after subtracting from such fair value
     any cost to Lessor for delivery of possession of the Unit of Equipment to
     Lessor at the end of the Term), which certification shall be signed by the
     manufacturer, engineer, property manager or the appraiser which determines
     the Stipulated Loss Value Schedule for such Unit of Equipment. The cost of

     (a)  Lessee covenants to pay to Lessor on the Rent Payment Date for each

schedule(s), Lessee shall complete and deliver to Lessor the Equipment Inventory
Schedule for such Billing Period. Payment by Lessee of the Rent indicated on the
Rent Schedule shall be deemed to be payment of the Rent due on the applicable
Rent Payment Date; provided, however, that any errors in the computation of Rent

may be corrected by submission of a revised Lessor Expense Schedule or a revised

debited, respectively, to the Rent due on the next Rent Payment Date. On or
before the applicable Rent Payment Date, Lessee shall deliver to Lessor one copy
of the signed and completed Rent Schedule and Equipment

on demand of Lessor, as additional rent ("Additional Rent") to Lessor or other
Persons entitled to receive the same the following:

          (i)  Lessee also shall pay out-of-pocket costs and expenses incurred
               by Lessor after the date hereof (including, without limitation,
               reasonable legal fees, expenses and disbursements reasonably
               incurred) associated with (A) negotiating and entering into, or
               giving or withholding of, any future amendments, supplements,
               waivers or consents with respect to this Lease, (B) any Casualty
               Occurrence or termination of this Lease and (C) any Event of
               Default and the enforcement of the rights or remedies of Lessor
               under this Lease. Nothing herein shall reduce or otherwise limit
               Lessee's obligations to Lessor pursuant to the indemnity
               provisions contained in Section 21 of this Lease.

          (ii) All other amounts that Lessee agrees herein to pay, including
               without limitation, interest at the Overdue Rate on any amounts
               not paid when due.

     In the event of any failure by Lessee to pay any Additional Rent hereunder,
Lessor shall have all the rights, powers and remedies as in the case of failure
to pay Rent.

     (c) This Lease is a completely net lease and Rent, Additional Rent and all
other sums payable by Lessee hereunder shall be paid without notice, demand,
counterclaim, setoff, deduction or defense and without abatement, suspension,
deferment, diminution or reduction of any kind whatsoever, except as herein
expressly otherwise provided. The preceding sentence shall not be construed as a
waiver of any counterclaim or defense which Lessee may be able to assert in a
proceeding at law or in equity. The obligations of Lessee to pay Rent,
Additional Rent and all other sums payable hereunder shall be absolute,
unconditional and irrevocable and shall continue unaffected by any event or
circumstance whatsoever including, without limitation: (i) any damage to or
loss, theft or destruction of the Equipment or any part thereof by any cause
whatsoever (including, without limitation, fire, casualty or act of God or enemy
or any other force majeure event); (ii) any requisition, taking or condemnation,
including, without limitation, a temporary requisition, taking or condemnation

(viii) any action of any Federal, state or local governmental authority; (ix)
any removal, abandonment, shutdown, salvage, or scrapping of the Equipment or
any part thereof; (x) to the maximum extent permitted by law, any insolvency,
bankruptcy, reorganization or similar proceeding by or against Lessee or Lessor
or any other Person; (xi) any lack of right, power or authority of Lessor or
Lessee to enter into this Lease or to perform the obligations hereunder, or any
doctrine of force majeure, impossibility, frustration, failure of consideration,
or any similar legal or equitable doctrine that Lessee's obligation to pay Rent
and all other sums payable by Lessee hereunder is excused because Lessee has not
received or will not receive the benefit for which it bargained, it being the
intent of Lessee to assume all risks from all causes whatsoever that it does not
receive such benefit; (xii) the breach or failure of any warranty,
representation or certification made in this Lease or any other instrument,
document or certificate delivered or to be delivered in connection herewith by
Lessor; or (xiii) any other cause or occurrence whatsoever, whether similar or
dissimilar to the foregoing, and shall be separate and independent covenants and
agreements, and all sums payable by Lessee hereunder shall be payable
unconditionally in all events, unless the requirement to pay or perform the same
shall have been modified or terminated pursuant to an express provision of this
Lease. Except as expressly provided herein, Lessee waives all rights now or
hereafter conferred by statute or otherwise to quit, terminate, modify or
surrender this Lease or any portion thereof, or to any abatement, suspension,
deferment, diminution or reduction of any sum payable by Lessee hereunder. All
covenants and agreements of the Lessee herein shall be performed at its cost,
expense and risk unless expressly otherwise stated. Nothing herein shall be
construed as a guaranty by the Lessee of any residual value in the Equipment nor
prevent the Lessee from asserting in any legal action any mandatory
counterclaim.

sales taxes and any net income, excess profits or with holding or franchise
taxes against Lessor on or measured by any monies payable hereunder or the net
income therefrom (including, without limitation, any payments made pursuant to
this sentence or pursuant to this Lease hereof and including, without
limitation, any personal property taxes on the Equipment and all other costs
assessed against Lessor on account of its acquisition, ownership, leasing or
disposing of the Equipment) (such Impositions other than those excluded by

provided, however, that Lessee shall not be obligated to pay (i) any Impositions

paid by Lessor as part of the Equipment Cost of any Unit of Equipment, (ii) any
Impositions which are based upon or measured by Lessor's net income, or which
are in substitution for, or relieve Lessor from, any actual Imposition based
upon or measured by Lessor's net income (excluding, however, Impositions imposed
with respect to the payment, 

                                      11
<PAGE>
 
receipt or accrual of any indemnity payment under this Lease) or (iii)
Impositions characterized under local law as franchise taxes (excluding,
however, any value-added, license, property or similar Impositions). Lessee
further agrees that, subject to its rights under Section 12 hereof, it will, at
its expense, do all things required to be done by Lessor in connection with the
levy, assessment, billing or payment of any such Impositions, and is hereby
authorized by Lessor to act for and on behalf of Lessor in any and all such
respects and to file, on behalf of Lessor, all tax returns and reports required
to be filed by Lessor (other than Federal income tax returns and documents
related thereto) concerning the Equipment. Lessee's payment obligations under
this Section 3(d) shall survive the termination of this Lease.

     (e)  (i)  In the event that any withholding or deduction from any payment
to be made by the Lessee hereunder is required in respect of any Taxes pursuant
to any applicable law, rule or regulation, then the Lessee will

          (x) pay directly to the relevant authority the full amount required to
          be so withheld or deducted;

          (y)  promptly forward to the Lessor an official receipt or other
          documentation satisfactory to the Lessor evidencing such payment to
          such authority; and

          (z)  pay to the Lessor such additional amount or amounts as is
          necessary to ensure that the net amount actually received by Lessor
          will equal the full amount Lessor would have received had no such
          withholding or deduction been required.

Moreover, if any Taxes are directly asserted against the Lessor with respect to
any payment received by the Lessor hereunder, the Lessor may pay such Taxes and
the Lessee will promptly pay such additional amounts (including any penalties,
interest or expenses) as is necessary in order that the net amount received by
such Person after the payment of such Taxes (including any Taxes on such
additional amount) shall equal the amount such Person would have received had
not such Taxes been asserted.

          (ii) If the Lessee fails to pay any Taxes when due to the appropriate
          taxing authority or fails to remit to the Lessor the required receipts
          or other required documentary evidence, the Lessee shall indemnify the
          Lessor for any incremental Taxes, interest or penalties that may
          become payable by Lessor as a result of any such failure.

     (f) Unless otherwise expressly provided, all payments by the Lessee
pursuant to this Lease shall be made by Lessee to the Lessor.  All such payments
required to be made to the Lessor shall be made, without setoff, deduction or
counterclaim, not later than 11:00 a.m., New York, New York time, on the date
due, in immediately available funds, to such account as the Lessor shall specify
from time to time by notice to Lessee.   Funds received after that time shall be
deemed to have been received by the Lessor on the next succeeding Business Day.
Whenever any 

                                      12
<PAGE>
 
payment to be made shall otherwise be due on a day which is not a Business Day,
such payment shall be made on the next succeeding Business Day and such
extension shall be included in computing Rent, Additional Rent, interest and
fees, if any, in connection with such payment.

     (g) Any payment of Rent or the Quarterly Expense Charge that is not paid
when due shall (to the fullest extent permitted by law) bear interest from and
including the date when due to but excluding the date of payment thereof at a
rate per annum equal to the Overdue Rate, payable upon demand.

Section 4.  Equipment Records and Schedules.
            ------------------------------- 

     Lessee shall maintain, on a current basis, books of proper record and
account in conformity with GAAP (to the extent applicable) which books shall
include, without limitation, (a) copies of all related contracts and any
amendments thereto, (b) the manufacturer, model and identification number, as
applicable, of each Unit of Equipment, (c) the location of each Unit of
Equipment, (d) the Equipment Cost of each Unit of Equipment, and (e) a copy of
the purchase invoice for each Unit of Equipment.

Section 5.  True Lease; Power of Attorney.
            ----------------------------- 

     (a) This Lease is an agreement of lease and does not convey to Lessee any
right, title or interest in the Equipment except as a lessee.

     (b) Pursuant to the terms of the Special Power of Attorney, Lessor or its
Funding Sources has designated Lessee as its attorney-in-fact for Equipment
Management and in respect of certain matters under the Facility Agreements.
Such Special Power of Attorney shall not amend, modify or supersede any of the
terms or provisions of this Lease in any way and, except as expressly permitted
by the terms of this Lease, does not and shall not be deemed to permit Lessee
(i) to abandon, salvage, dispose, bargain, sell, convey or contract for the sale
or conveyance of Units of Equipment, (ii) to demand, sue for, collect, recover
or receive any moneys or sums in the name of Lessor or any Person, or (iii)
execute any instrument or document on behalf of Lessor or any Person.

Section 6.  Removals Without Replacements.
            ----------------------------- 

     Unless, an Event of Default shall occur and be continuing, Lessee may, upon
at least 10 Business Days' prior written notice to Lessor, remove any Unit of
Equipment or part thereof at its own expense without replacing it (provided that
such Unit of Equipment or part thereof is inappropriate or no longer
functionally useful to Lessee for the intended use of the Equipment by Lessee),
and title to such Unit of Equipment or part thereof shall vest in Lessee free
and clear of all rights of Lessor, provided that such removal and nonreplacement
does not in any material respect (i) diminish or impair the value, utility and
useful life of the Equipment (subject to normal interruption in the ordinary
course of business for maintenance, inspection, service, repair and testing) or

                                      13

(ii) result in the Equipment becoming "limited use property" within the meaning
of Rev. Proc. 76-30, 1976-2 C.B. 647 (assuming, in each case, the Equipment was
then of the value, utility and useful life required to be maintained hereunder).
Lessee shall give prompt notice to Lessor of any warranty claim made by Lessee
against any manufacturer, supplier, contractor, or Vendor of any Unit of
Equipment.

 
Section 7.  Payment of Impositions; Further Assurances.
            ------------------------------------------ 

     (a) Subject to Section 12 hereof, Lessee will pay all Impositions before
any fine, penalty, interest or cost may be added thereto for nonpayment and
before nonpayment might result in a Lien or Judgment, and will furnish to
Lessor, upon request, copies of official receipts or other satisfactory proof
evidencing such payment.

     (b)  Lessee, at its expense, shall execute, acknowledge and deliver from
time to time such further counterparts of this Lease or such affidavits,
certificates, certificates of title, bills of sale, financing and continuation
statements, consents and other instruments as may be reasonably requested by
Lessor in order to evidence Lessor's or its Funding Sources' title to the Units
of Equipment and Lessor's interests in this Lease, and shall at Lessor's request
and at Lessee's expense cause such documents to be recorded, filed or registered
in such places as Lessor may request and to be re-recorded, refiled or re-
registered in such places at such times as may be required by applicable law in
order to maintain and continue in effect the recordation, filing or registration
thereof.  Unless an Event of Default shall have occurred and be continuing,
Lessor or its Funding Sources shall not grant or create any Lien on any Unit of
Equipment to any Person, except the Operator's Lien under the Facility
Agreements securing amounts not then due and payable.

     (c)  Lessee shall keep all Units of Equipment in the Mississippi Canyon
Blocks 441, 442 and 485 and Ewing Bank Block 482 Offshore Louisiana, Gulf of
Mexico, or in Lessee's facility located in LaFourche Parish, Louisiana (except
for Units of Equipment that are in transit to such Blocks in the Gulf of Mexico
or to such facility of Lessee); and except for Units of Equipment having an
aggregate value (such value being the Stipulated Loss Value of such Unit of
Equipment), as to Lessor's or its Funding Sources' interest, of less than
$375,000, and any parts of any Units of Equipment having an individual value
(such value being the original cost of such part), as to Lessor's or its Funding
Sources' interest, of less than $75,000, that are removed from such Blocks for
repairs in the ordinary course of business), or, upon 30 days' prior written
notice to the Lessor, at such other places such that all action required or
requested pursuant to Section 7(b) shall have been taken with respect to the
Equipment; provided, however, that no Equipment shall be located in, on or above
           --------  -------                                                    
or used in connection with any oil or gas reserves other than the Reserves,
except that the foregoing proviso shall not prohibit the Equipment being used to
produce additional reserves other than the Reserves so long as such production
does not interfere 

                                      14

with production of the Reserves and such production of the Reserves continues.

Section 8.  Compliance with Insurance Requirements and Facility Agreements.
            -------------------------------------------------------------- 

     Lessee at its expense will promptly comply with all Insurance Requirements,
and any other instruments, contracts or agreements affecting title to or
ownership of the Equipment.  The Lessee shall, and (so long as no Event of
Default has occurred) is hereby authorized by Lessor to, fully and promptly
keep, observe, perform and satisfy, on behalf of Lessor, and on behalf of itself
as Operator under the Operating Agreements and as a party thereto, any and all
obligations, conditions, covenants and restrictions of or on the Lessor or
itself, as the case may be, under any and all Facility Agreements so that there
will be no breach or default thereunder and so that the other parties thereunder
shall be and remain at all times obliged to perform their obligations
thereunder, and the Lessee, to the extent within its control, shall not permit
to exist any condition, event or fact that could allow or serve as a basis or
justification for any such Person to avoid such performance. Lessee shall
further pay all costs, taxes and amounts from time to time required to be paid
under or pursuant to any of the Facility Agreements and will not amend any
Facility Agreement in any way which would have a material adverse effect upon
the ability of Lessor or Lessee to perform its respective agreements under this
Lease or in any way which would have a material adverse effect on the rights of
the Lessor under this Lease or in any way which would create or purport to
create any liability on the part of the Lessor under any Facility Agreement
without the prior written consent of the Lessor.

Section 9.  Condition and Use of Equipment; Assignment of Warranties, Etc.;
            ---------------------------------------------------------------
            Quiet Enjoyment; Leasehold and Other Interests.
            ---------------------------------------------- 

     (a)  The Equipment is leased AS IS, WHERE IS, AND WITH ALL FAULTS and in
the condition thereof and subject to the rights of any parties in possession
thereof, the state of the title thereto, and the rights of ownership therein,
including, without limitation, pursuant to the Facility Agreements, in each case
as in existence when the same first becomes subject to this Lease, without
representations and warranties of any kind as to title by Lessor,  its Funding
Sources or any Person acting on behalf of any of them.  LESSEE ACKNOWLEDGES AND
AGREES THAT LESSOR HAS LEASED TO LESSEE AN UNDIVIDED PERCENTAGE INTEREST IN THE
EQUIPMENT AND THAT LESSOR (i) IS NOT A MANUFACTURER OF, OR VENDOR OF, OR
MERCHANT WITH RESPECT TO, ANY OF THE EQUIPMENT OR ANY PROPERTY OF SUCH KIND,

FITNESS FOR A PARTICULAR PURPOSE OR OTHERWISE, DESIGN, CONDITION, QUALITY OF
MATERIAL OR WORKMANSHIP, CONFORMITY TO SPECIFICATIONS, FREEDOM FROM PATENT OR
TRADEMARK INFRINGEMENT, ABSENCE OF ANY LATENT OR OTHER DEFECTS, WHETHER OR NOT
DISCOVERABLE, WHETHER ARISING PURSUANT TO THE UNIFORM COMMERCIAL CODE OR ANY
OTHER PRESENT OR FUTURE LAW OR OTHERWISE, AND 

                                      15

(iii) SHALL NOT BE LIABLE FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES (INCLUDING
LIABILITY IN TORT, STRICT OR OTHERWISE). LESSEE ACKNOWLEDGES AND AGREES THAT (a)
EACH UNIT OF EQUIPMENT IS OF A SIZE, DESIGN, CAPACITY AND MANUFACTURE
SATISFACTORY TO LESSEE, AND (b) LESSEE IS SATISFIED THAT THE SAME IS SUITABLE
FOR ITS PURPOSES.

     (b)  Lessor hereby assigns to Lessee any and all warranties and indemnities
of and claims against any manufacturers or Vendors relating to any Unit of
Equipment (including any equipment or parts supplied therewith), and to the
extent assignment of the same is prohibited or precludes enforcement of any such
warranty or undertaking, Lessor hereby subrogates Lessee to its rights in
respect thereof; provided, that such assignment shall remain in effect only so
                 --------                                                     
long as no Event of Default has occurred and is continuing and no condition,
occurrence or event exists or has occurred which, after notice or lapse of time
or both, would constitute an Event of Default.  Lessor hereby authorizes Lessee,
at Lessee's expense, to assert any and all claims, to prosecute any and all
suits, actions and proceedings, in its own name or in the name of Lessor, in
respect of any such warranty or undertaking and to retain the proceeds received.
Notwithstanding anything else in this Section 9(b), Lessor shall have the rights
conferred on Lessee in this Section 9(b) if Lessor incurs any unindemnified
damage or liability relating to or in connection with any manufacturer's or
Vendor's warranty or undertaking.

     (c)  The following provisions relate to each contract, permit and license
(an "Instrument") necessary in connection with the ownership and operation of
the Equipment:

          (i)   The Lessee covenants and agrees to perform and to observe all of
                the terms, covenants, provisions, conditions and agreements of
                the underlying Instruments including, without limitation,
                payment of all rent, additional rent and other charges payable
                under the Instrument.

          (ii)  Lessee covenants and agrees that it will not do, or cause to be
                done or suffer or permit, any act or thing to be done which
                would or might cause such Instrument to be terminated or make
                the Lessor liable for any losses, costs, liabilities, damages,
                claims, penalties or other expenses arising out of or related to
                such Instrument.

          (iii) If any Instrument shall expire, terminate or otherwise be
                extinguished, the Lessee shall notify Lessor of any such
                occurrence, describing the nature, scope, and extent of the
                Instrument so expired, terminated or extinguished, then the
                Lessee shall promptly replace, at its sole cost and expense,
                such Instrument with a new instrument granting, in all material
                respects, the same rights under the expired, terminated or
                extinguished Instrument.

<PAGE>
 
     (d)  As between Lessee and Lessor, so long as no Event of Default shall
have occurred and be continuing and no condition, occurrence or event exists or
has occurred which, after notice or lapse of time or both, would constitute an
Event of Default, Lessee shall have the right, subject to the terms and
provisions of the Facility Agreements, to exclusive possession and use of the
Equipment as to its proportionate interest therein.

     (e)  Lessee will not do or fail to do, or knowingly permit, any act or
thing which action or thing or failure might impair the value or usefulness of
the Equipment as an integrated system for the production and safe and lawful
handling of hydrocarbons and other functions contemplated by the design of such
Equipment, ordinary wear and tear excepted.

Section 10.  Maintenance and Replacement of the Equipment; Operations.
             -------------------------------------------------------- 

     (a)  Lessee, at its own expense, will cause the Equipment to be maintained
in good operating order, repair and condition, in accordance with prudent
industry practice and any applicable manufacturers' manuals or warranties,
subject to normal wear and tear, and will use best efforts to comply with all
governmental laws, rules and regulations from time to time applicable to the
maintenance and operation of the Equipment and will comply with all governmental
laws, rules and regulations from time to time applicable to the maintenance and
operation of the Equipment the noncompliance with which would result in any
material liability of Lessor or any criminal liability of any of Lessor, or any
of Lessor's officers, directors, incorporators, shareholders, controlling
Persons, employees or agents.  Lessee shall maintain the Units of Equipment at
its own expense as a prudent operator in the same or similar circumstances and
in accordance with its obligations under the Facility Agreements.  Lessee at its
own expense will cause the Equipment to continue to have at all times the
capacity and functional ability to perform, on a continuing basis (subject to
normal interruption in the ordinary course of business for maintenance,
inspection, service, repair and testing) and in commercial operation, the
functions for which it was designed.

     (b)  Lessee, at its own cost and expense, will promptly replace, or cause
to be replaced, all Units of Equipment or parts thereof which may from time to
time be incorporated or installed in or attached to the Equipment and which may
from time to time become worn out, lost, stolen, destroyed, seized, confiscated,
damaged beyond repair or permanently rendered unfit for use for any reason
whatsoever.  All replacement Units of Equipment or parts thereof shall be free
and clear of all Liens (other than Permitted Liens), shall be in as good
operating condition as, and shall have a utility at least equal to, the Units of
Equipment or parts thereof replaced (assuming such replaced parts were in the
condition and repair required to be maintained by the terms hereof) and shall
have a value at least equal to the Units of Equipment or parts replaced
(assuming such replaced parts and the Equipment were in the condition and repair
required to be maintained by the terms hereof).

                                      17
<PAGE>
 
     (c)  All Units of Equipment or parts at any time removed from the Equipment
shall remain the property of (and title thereto shall remain in) Lessor or its
Funding Sources, no matter where located, until such time as such  Units of
Equipment or parts shall be replaced by replacement  Units of Equipment or parts
which have been incorporated or installed in or attached to the Equipment and
which meet the requirements for replacement  Units of Equipment or parts
specified above.  Immediately upon any replacement part becoming incorporated or
installed in or attached to the Equipment as above provided, without further act
or instrument, (i) title to the removed Equipment or part thereof shall
thereupon vest in Lessee, free and clear of all rights of Lessor, and shall no
longer be deemed Equipment hereunder; (ii) title to such replacement Equipment
or part shall thereupon vest in Lessor; and (iii) such replacement Unit of
Equipment or part shall become subject to this Lease and be deemed part of the
Equipment for all purposes hereof to the same extent as the Units of Equipment
or parts thereof originally incorporated or installed in or attached to the
Equipment prior thereto.

     (d)  The Lessee shall, and it shall require and ensure that any and all
employees, contractors, subcontractors, agents, representatives, affiliates,
consultants, occupants and any and all other Persons, at Lessee's expense, (i)
comply in all material respects with all applicable Environmental Laws, and (ii)
use, employ, process, emit, generate, store, handle, transport, dispose of
and/or arrange for the disposal of, any and all Hazardous Materials in, on or,
directly or indirectly, related to or in connection with the Equipment or any
part thereof in a manner consistent with prudent industry practice and in
compliance in all material respects with any applicable Environmental Law, and
in a manner which does not pose a significant risk to human health or the
environment.  Lessor and Lessee hereby acknowledge and agree that Lessee's
obligations hereunder with respect to Hazardous Materials and Environmental Laws
are intended to bind the Lessee with respect to matters and conditions in, on,
under, beneath, with respect to, affecting, related to, in connection with or
involving the Equipment or any part thereof.  Lessee, at its expense, will
register and re-register the Equipment when necessary under applicable law.

     (e)  Lessee will, at its expense, maintain or cause to be maintained and
shall permit Lessor to inspect any records, logs and other materials required by
any Facility Agreement or any governmental authority having jurisdiction to be
maintained or filed in respect of the Equipment.

     (f)  Notwithstanding the provisions of Section 6 and the foregoing
provisions of this Section 10, Lessee shall not remove, replace or alter any
Unit of Equipment or affix or place any accessory, equipment or device on any
Unit of Equipment, if such removal, replacement, alteration or addition would
impair the originally intended function or use of such Unit of Equipment so as
to materially reduce the value of the Equipment, taken as a whole.

clauses (ii) and (iii) of the proviso of the penultimate sentence of Section
3(d)) or any Lien of the type described in Section 11(a)(iii) hereof; provided,

subject to the express written consent of Lessor if such actions would subject
Lessor or its Funding Sources to any criminal liability or sanction for failure
to pay any such Imposition or Lien. Lessee will pay, and save Lessor and its
Funding Sources harmless against, all losses, judgments, decrees and reasonable
costs, including attorneys' fees and expenses, in connection with any such

foregoing coverages in a manner and to the extent such self-insurance is
consistent with the self-insurance practices of other companies of the same size
or credit rating of Lessee in the off-shore energy exploration and production
industry.

     If self-insurance is not utilized, such insurance shall be written by
companies selected by the Lessee and acceptable to the Lessor and, with respect
to the insurance specified in clause (iii) shall include Lessor and its Funding
Sources as additional insureds to the extent Lessee has agreed to indemnify such
herein, and with respect to the insurance specified in clauses (i) and (ii)
shall include Lessor and its Funding Sources as loss payees as their interests
may appear.

     (b)  The property insurance referred to in subparagraph (a)(i) for the
Equipment and builder's risk insurance referred to in subparagraph (a)(ii) may
be a blanket policy and (i) shall at all times be in an amount at least equal to
the Stipulated Loss Value for each Unit of Equipment and (ii) any loss or damage
under such property insurance 

                                      20
<PAGE>
 
policy and builder's risk insurance policy other than proceeds representing
compensation for business interruption shall be payable to the Lessor to be held
and applied pursuant to the terms of this Lease. Every policy required under
paragraph (a) shall (i) expressly provide that it will not be canceled or
terminated due to a lapse for non-payment of premium except upon thirty (30)
days' written notice to the Lessor and the Lessee; (ii) intentionally omitted;
(iii) intentionally omitted; (iv) include a waiver of all rights of subrogation
against the Lessor and its Funding Sources and any recourse against Lessor and
its Funding Sources for payment of any premiums or assessments under any policy;
and (v) not contain a provision relieving the insurer thereunder of liability
for any loss by reason of the existence of other policies of insurance covering
the Equipment or any part thereof against the peril involved (unless Lessee
shall not have any such other policies), whether collectible or not, if such
other policies do not name Lessor and its Funding Sources as additional
insureds. The Lessee shall advise the Lessor promptly of any policy cancellation
or any change adversely affecting the coverage provided thereby.

     (c)  On or before the Lease Commencement Date (or such other later date as
Lessee and Lessor shall agree upon in writing), where self-insurance is not
utilized, Lessee will provide Lessor with insurance certificates from insurance
brokers in respect of the insurance required by Section 13(a), and thereafter,
as appropriate, Lessee will give notice as to any material change in the nature
of such coverage. The Lessee shall notify Lessor of any nonrenewal of any policy
required hereunder. The Lessee shall not obtain or carry separate insurance
concurrent in form, or contributing in the event of loss, with that required by
Section 13(a)(i) or (ii) unless the Lessor is included as additional loss payee
therein, with loss payable as provided in this Lease. The Lessee shall
immediately notify the Lessor whenever any such separate insurance is obtained
and shall deliver to the Lessor the certificates of insurance evidencing the
same as is required hereunder. Any insurance required hereunder may be provided
under Lessee's blanket policies; provided that the coverage allocable to the
Equipment is not less than the coverage required by this Section as separately
stated.


Section 14.  Required and Optional Alterations; Title to Alterations.
             ------------------------------------------------------- 

     (a)  Lessee at its own cost and expense, shall make (or cause to be made)
all Alterations to the Equipment as may be required from time to time to meet in
all material respects all requirements under applicable law (regardless of the
Person upon whom such requirements, by their terms, are nominally imposed),
except to the extent being contested in accordance with Section 12 hereof.

     (b)  Unless an Event of Default shall have occurred and be continuing,
Lessee, at its own cost and expense, may from time to time make, subject to
obtaining all necessary authorizations, consents or approvals of any
governmental authority and consents of Third Parties, such Alterations to the
Equipment that are not required pursuant to Section 14(a) hereof as Lessee may
deem desirable in the proper conduct 

                                      21
<PAGE>
 
of its business, provided that (i) such Alteration shall not diminish or impair
in any material respect the value, utility or useful life of the Equipment
(subject to normal interruption, in the ordinary course of business for
maintenance, inspection, service, repair and testing), (ii) such Alteration
shall not cause the Equipment to constitute "limited use property" within the
meaning of Rev. Proc. 76-30, 1976-2 C.B. 647 and (iii) no Alterations, taken
together or separately, shall violate the provisions of Rev. Proc. 75-21, 1975-1
C.B. 715 or 79-48, 1979-1 C.B. 529.

     (c)  Title to each Alteration shall without further act or instrument vest
in the Lessor and be deemed to constitute a part of the Equipment and be subject
to this Lease, provided that any such Alteration is required pursuant to Section
14(a) hereof or is a Nonseverable Alteration.  Title to all other Alterations
shall vest in the Lessee or such other Person as the Lessee shall select, and
the Lessee may finance the acquisition thereof in whatever manner it elects,
secured or unsecured, provided that such financing does not and will not result
in any Lien (other than Permitted Liens) on or with respect to the Equipment or
any part thereof. Any such Alteration may be removed by the Lessee or any Person
having a Lien thereon, at its own cost and expense, at any time prior to the
Stated Lease Termination Date if the conditions set forth in clauses (i) and
(ii) of the proviso contained in Section 14(b) hereof are met and such removal
will not cause any of the Equipment to be in violation of any applicable legal
requirement. Any such Alteration may also be removed at the Stated Lease
Termination Date upon not less than 90 days' prior written notice to Lessor, so
long as the Equipment is restored substantially to its condition (normal wear
and tear excepted) prior to the making of such Alteration, provided that such
removal does not diminish or impair the performance of the Equipment at such
time; and provided, further, that any Severable Alterations that are not removed
from the Equipment at the time of its surrender by the Lessee shall become the
property of the Lessor.

Section 15.  Events of Default and Remedies.
             ------------------------------ 

     (a)  Each of the following acts or occurrences shall constitute an "Event
of Default" hereunder:

          (i)   default in the payment of Rent and Additional Rent when due and
                the continuance of such default for 5 days thereafter (the
                Lessor shall use reasonable efforts to give notice to Lessee of
                such default, but failure by the Lessor to give such notice
                shall in no way constitute a default by the Lessor under this
                Lease); or

          (ii)  default in the payment of any other amount payable by Lessee to
                Lessor hereunder for 15 days after notice to Lessee of such

          (iii) default by Lessee in the performance of any other covenant,
                liability or obligation of Lessee to Lessor

<PAGE>
 
                and the continuance of such default for 30 days after notice to
                Lessee of such default from Lessor; or

          (iv)  any representation or warranty made by Lessee herein or
                otherwise in writing in connection with or pursuant to this
                Lease shall be false or misleading in any material adverse
                respect on the date as of which made or reaffirmed and not cured
                for 30 days after any such representation or warranty is
                discovered by Lessee to have been false or misleading on the
                date made or reaffirmed; or

          (v)   Lessee shall (A) voluntarily commence any proceeding or file any
                petition seeking relief under Title 11 of the United States Code
                or any other Federal or state bankruptcy, insolvency or similar
                law, (B) consent to the institution of any such proceeding or
                the filing of any such petition, (C) apply for or consent to the
                appointment of a receiver, trustee, custodian, sequestrator or
                similar official for Lessee or for a substantial part of its
                property, (D) file an answer admitting the material allegations
                of a petition filed against it in any such proceeding, (E) make
                a general assignment for the benefit of creditors, (F) admit in
                writing its inability or fail generally to pay its debts as they
                become due, or (G) take partnership or corporate action for the
                purpose of effecting any of the foregoing; or

          (vi)  an involuntary proceeding shall be commenced or an involuntary
                petition shall be filed in a court of competent jurisdiction
                seeking (A) relief in respect of Lessee or of a substantial part
                of its property, under Title 11 of the United States Code or any
                other Federal or state bankruptcy, insolvency or similar law,
                (B) the appointment of a receiver, trustee, custodian,
                sequestrator or similar official for Lessee or for a substantial
                part of its property or (C) the winding-up or liquidation of
                Lessee; and such proceeding or petition shall continue
                undismissed for 60 days and the Lessor determines in its sole
                discretion that such proceeding or petition is not frivolous and
                notifies the Lessee of such determination (it being understood
                that Lessor need not make any investigation), or an order or
                decree approving or ordering any of the foregoing shall continue
                unstayed and in effect for 60 days; or

          (vii) an event of default as defined in any mortgage, indenture,
                instrument, or loan agreement under which at the time of such
                event of default there has been issued, or by which there has
                been secured or evidenced, any indebtedness of Lessee for money
                borrowed or for the deferred purchase price of 

                                      23
<PAGE>
 
                property, shall occur and shall result in indebtedness in excess
                of $25,000,000 in the aggregate becoming due and payable prior
                to the due date thereof, or any such event of default shall
                occur thereunder (including the giving of notice and lapse of
                grace period, if any) which would permit the holder of such
                indebtedness to declare the same due and payable prior to its
                stated maturity or due date and such event shall continue for
                more than the period of grace, if any, therein specified and a
                valid waiver shall not be in effect; or

         (viii) Lessee shall default in the payment when due (subject to any
                applicable grace period) whether by acceleration or otherwise,
                of any obligations (a) for borrowed money or (b) for the
                deferred purchase price of property, or a default shall occur in
                the performance or observance of any covenant, agreement or
                condition with respect to any of the obligations described in
                clauses (a)or (b) above if the effect of such default is to
                accelerate the maturity or term of any such obligation or such
                default shall continue unremedied for any applicable period of
                time sufficient to permit the holder or holders of such
                obligation, or any trustee or agent for such holders, to cause
                such obligation to become due and payable prior to its expressed
                maturity or term; or

         (ix)   Lessee shall receive notice from the Pension Benefit Guaranty
                Corporation indicating that it has made a determination that it
                will invoke its right under Section 4042(a) of the Employee
                Retirement Income Security Act of 1974 ("ERISA") to terminate
                any employee pension benefit plan ("Plan") maintained by Lessee
                for its employees and covered by Title IV of ERISA and such
                determination is not being contested in good faith and by proper
                proceedings by Lessee within 60 days following the receipt of
                such notice, or the Pension Benefit Guaranty Corporation
                institutes proceedings to terminate, or in connection with
                proceedings to terminate has a trustee appointed to administer
                any Plan maintained by Lessee, and such proceedings to terminate
                are not stayed or dismissed within 60 days following their
                institution, or Lessee becomes subject to employer liability
                under Sections 4062, 4063 or 4064 of ERISA in connection with a
                Plan maintained by Lessee; or

         (x)    The occurrence of any environmental event involving, or the
                discovery of any environmental condition in, on, beneath or
                involving, any Unit of the Equipment (including, but not limited
                to, the presence, emission or release of Hazardous Materials or
                the violation of any applicable Environmental Law) that

                would have a material adverse effect on the use, occupancy,
                possession, value or condition of any Unit of Equipment or which
                would reasonably be expected to have a material adverse effect
                on the financial condition, operations, assets, business,
                properties or prospects of Lessee and which is not remedied
                within sixty days after the occurrence or discovery of such
                event or condition; or

         (xi)   INTENTIONALLY OMITTED

         (xii)  Lessee shall cease for any reason to be the operator under each
                of the Operating Agreements; or

         (xiii) An application is filed with the Minerals Management Service,
                U.S. Department of Interior (or any successor thereto), to
                abandon any Unit of Equipment; or

         (xiv)  Lessee shall withdraw from any Operating Agreement; or

         (xv)   Any party to any Operating Agreement shall commence enforcement
                of a lien granted by Lessee in its capacity as operator or
                interest owner pursuant to such Operating Agreement; or

         (xvi)  Lessee's Articles of Incorporation or Bylaws shall be amended,
                supplemented or otherwise modified, or any provision thereof
                shall be waived, or Lessee shall attempt to amend, supplement
                or otherwise modify its Articles of Incorporation or Bylaws or
                waive any provision thereof, which amendment, supplement,
                modification or waiver would, in the reasonable opinion of
                Lessor, have a material adverse effect on the Lessee's ability
                to perform its obligations under and in connection with this
                Lease; or

         (xvii) Any Operating Agreement shall be amended, supplemented or
                otherwise modified, or any provision thereof shall be waived,
                which amendment, supplement, modification or waiver would, in
                the reasonable opinion of Lessor, (a) have a material adverse
                effect on the Lessee's ability to perform its obligations under
                and in connection with this Lease or (b) create or purport to
                create, any liability in respect of Lessor or its Funding
                Sources.

     (b) If an Event of Default shall have occurred and be continuing, Lessor
may, at its option, by notice to Lessee declare this Lease to be in default, and
at any time thereafter Lessor may exercise one or more of the following as
Lessor in its sole discretion shall elect:

                                      25

          (i)   Lessor may, by notice to Lessee, rescind or terminate this Lease
     and all rights of Lessee hereunder to the use and possession of the
     Equipment;

          (ii)  Lessor may (A) demand that Lessee, and thereupon Lessee shall,
     return the Equipment promptly to Lessor in the manner and condition
     required by, and otherwise in accordance with the provisions of, this Lease
     as if the Equipment were being returned at the end of the Term and Lessor
     shall not be liable for the reimbursement of Lessee for any costs and
     expenses incurred by Lessee in connection therewith, (B) take immediate
     possession of (to the exclusion of Lessee) the Equipment, by summary
     proceedings or otherwise, all without liability of Lessor to Lessee (or to
     any Person claiming by, through or under Lessee) for or by reason of such
     entry or taking of possession, whether for the restoration of damage to
     property caused by such taking or otherwise, except damage caused by
     Lessor's negligence or willful misconduct, and (C) have the option to
     exercise the Lessor Purchase Option (and any amounts owed to Lessee
     pursuant to such exercise shall be, at Lessor's option, either remitted to
     Lessee or applied by Lessor to offset amounts owed by Lessee hereunder);

          (iii) Whether or not any action has been taken under clause (i) or
     (ii) above, Lessor may sell the Equipment or any part thereof at public or
     private sale, as Lessor may determine, with or without notice to Lessee,
     advertisement or publication, free and clear of any rights of Lessee or of
     any Person claiming by, through or under Lessee and without any duty to
     account to Lessee with respect to such sale or any proceeds with respect
     thereto (except to the extent required by clause (v) or (vi) below if
     Lessor shall elect to exercise its rights thereunder), in which event
     Lessee's obligation to pay Rent hereunder for periods commencing after the
     date of such sale shall be terminated (except to the extent that Rent is to
     be included in computations under clause (v) or (vi) below if Lessor shall
     elect to exercise its rights thereunder);

          (iv)  Lessor may hold, keep idle, use, operate or lease to others all
     or any part of the Equipment as Lessor in its sole discretion may
     determine, free and clear of any rights of Lessee (or any Person claiming

     to any Person claiming by, through or under Lessee with respect to such
     action or inaction or for any proceeds with respect to such action or
     inaction, except that Lessee's obligation to pay Rent for periods
     commencing after Lessee shall have been deprived of use of the Equipment
     pursuant to this clause (iv) shall be reduced by the net proceeds, if any,
     received by Lessor from leasing the Equipment to any Person other than
     Lessee for the same periods or any portion thereof;

          (v)   Lessor may, whether or not Lessor shall have exercised or shall
     thereafter at any time exercise its rights under clause (ii), (iii) or (iv)
     above, demand, by written notice to Lessee specifying a payment date which
     shall be a Rent Payment Date not earlier than 10 days after the date of
     such notice, that Lessee 

                                      26

     pay to Lessor, and Lessee shall pay to Lessor, on the Rent Payment Date
     specified in such notice, as liquidated damages for loss of a bargain and
     not as a penalty (in lieu of Rent due after the Rent Payment Date specified
     in such notice), any unpaid Rent due through the Rent Payment Date
     specified in such notice plus whichever of the following amounts Lessor, in
     its sole discretion, shall specify in such notice (together with interest
     on such amount at the Overdue Rate from the Rent Payment Date specified in
     such notice to the date of actual payment);

                (A) if Lessor takes possession of the Equipment, an amount equal
          to the excess, if any, of such Stipulated Loss Value over the Fair
          Value of the Equipment as of the Rent Payment Date specified in such
          notice;

                (B) if Lessor takes possession of the Equipment, an amount equal
          to the excess of (1) the present value as of the Rent Payment Date
          specified in such notice of all remaining installments of Rent until
          the end of the Basic Term or Fair Market Renewal Term, as the case may
          be, discounted semiannually at a rate of 10% per annum, over (2) the
          present value as of such payment date of the Fair Market Rental Value
          of the Equipment until the end of the Basic Term or the Fair Market
          Renewal Term, as the case may be, discounted semiannually at a rate of
          10% per annum; or

                (C) an amount equal to the Stipulated Loss Value, computed as of
          the Rent Payment Date specified in such notice, and upon payment
          thereof and all other amounts then due by Lessee hereunder, Lessor
          shall Transfer the Equipment to Lessee;

          (vi)  If Lessor shall have sold all the Equipment pursuant to clause
     (iii) above, Lessor, in lieu of exercising its rights under clause (v)
     above with respect to the Equipment, may (but shall not be obligated to)
     demand that Lessee pay to Lessor and Lessee shall pay to Lessor on the date
     of such sale, as liquidated damages for loss of a bargain and not as a
     penalty (in lieu of Rent due for periods commencing after the next Rent
     Payment Date following the date of such sale), any unpaid Rent due through
     such Rent Payment Date, plus the amount of any deficiency between
     Stipulated Loss Value, computed as of such Rent Payment Date, and the net
     proceeds of such sale, together with interest at the Overdue Rate on the
     amount of such Rent and such deficiency from the date of such sale until
     the date of actual payment; or

          (vii)   Lessor may exercise any other right or remedy that may be
     available to it under applicable law or proceed by appropriate court action
     to enforce the terms hereof or to recover damages for the breach hereof.

     (c)  In addition to the foregoing, Lessee shall be and remain liable for
paying or reimbursing Lessor for (i) any and all Rent and other amounts due and
payable under this Lease prior to any such Event 

                                      27
<PAGE>
 
of Default, and (ii) all costs and expenses incurred by Lessor (including
reasonable fees and expenses of counsel) in connection with any exercise of its
remedies provided in this Section 15(c).

     (d)  No rescission or termination of this Lease, in whole or in part, or
repossession of the Equipment or exercise of any remedy under Section 15(b)
shall, except as specifically provided therein, relieve Lessee of any of its
liabilities and obligations hereunder.  In addition, Lessee shall be liable,
except as otherwise provided above, for any and all unpaid Rent due hereunder
before, after or during the exercise of any of the foregoing remedies, including
all reasonable legal fees and other costs and expenses incurred by Lessor by
reason of the occurrence of any Event of Default or the exercise of Lessor's
remedies with respect thereto and including all costs and expenses incurred in
connection with the return of the Equipment in the manner and condition required
by, and otherwise in accordance with the provisions of, this Lease as if the
Equipment were being returned at the end of the Term. At any sale of the
Equipment or any part thereof pursuant to Section 15(b), Lessor may bid for and
purchase such property.

     (e)  To the extent permitted by, and subject to the mandatory requirements
of, applicable law, each and every right, power and remedy under Section 15(b)
or otherwise available to Lessor shall be cumulative and shall be in addition to
every other right, power and remedy, and each and every right, power and remedy
may be exercised from time to time and as often and in such order as may be
deemed expedient by Lessor, and the exercise or the beginning of exercise of any
such right, power or remedy shall not exhaust the same or be construed to be a
waiver of the right to exercise at the same time or thereafter the same or any
other right, power or remedy.  No delay or omission by Lessor in the exercise of
any right, power or remedy shall restrict Lessor from exercising the same or
any other right, power or remedy thereafter nor be construed to be a waiver of
any Event of Default or to be an acquiescence therein.  No express or implied
waiver by Lessor of any Event of Default shall in any way be, or be construed to
be, a waiver of any future or subsequent Event of Default.

Lessor and its Funding Sources and as otherwise may be reasonably requested),
(i) within 90 days after the end of each quarter of each fiscal year of Lessee,
a statement, executed by an Authorized Officer of Lessee, certifying (A) the
dates to which the sums payable hereunder have been paid, that this Lease is
unmodified and in full force and effect (or, if there have been modifications
thereto, that this Lease is in full force and effect as modified), (B) that no
Event of Default and, to the best of the knowledge of Lessee, no event which,
with the giving of notice or the lapse of time, or both, would become such an
Event of Default, has occurred and is continuing (or specifying the nature and
period of existence of any thereof and what action Lessee is taking or proposes
to take with respect thereto), and (C) that the representations and warranties
of Lessee set forth in Section 20 hereof are true with the same effect as though
such representations and warranties had been made on the date of such statement
(except for any such representations and warranties which expressly relate to an
earlier date), it being intended that any such statement may be relied upon by
Lessor, and (ii) promptly upon acquiring actual knowledge of the occurrence of
an Event of Default or the occurrence or existence of any condition, occurrence
or event which, after notice or lapse of time or both, would constitute an Event
of Default, written notice specifying the nature and period of existence thereof

     (b)  Lessee will deliver to Lessor (in as many copies as to provide one for
Lessor and its Funding Sources and as Lessor may otherwise reasonably request)
with all reasonable promptness, such other information respecting the condition
or operations, financial or otherwise, of the Lessee, as the Lessor may from
time to time reasonably request in order to evaluate the Lessee's ability from
time to time to fulfill its obligations under the Lease so long as the Lessor
states at the time that the Lessor believes the Lessee may be unable ultimately
to fulfill such obligations.

"Reserves") attributable to the oil and gas leases and the lands affected
thereby (as more fully described on Schedule F hereto) on which any Unit of
Equipment is located or in connection with which any Unit of Equipment is
purchased, leased or used and a projection of future production, associated
costs, future net revenue and present value in respect of such Reserves; such

officer of Lessee as to the status of the Equipment, containing a brief
description and the value of any Units of Equipment replaced, or any part

Section 7(c) herein  on the Equipment since the Lease Commencement Date, or
since the date of the prior report delivered by Lessor to its Funding Sources
and certifying that the Equipment is in good operating order, repair and
condition and that Lessee has complied with all other covenants and agreements
of Lessee set forth in Section 10 hereof.

     (f)  Lessor shall use reasonable efforts to deliver to Lessee, upon
Lessee's request (such request to be made no more than once to Lessor in any
calendar year) a certificate substantially in the form of Schedule K hereto;
provided, however, that failure by Lessor to deliver such certificate shall in
- --------  -------                                                             
no way constitute a default by Lessor hereunder and shall in no way relieve
Lessee of its obligations hereunder.

     (g)  Lessee shall deliver to Lessor concurrently with the annual report
referred to in Section 17(e) above, (1) certificates of insurance (or other
evidence acceptable to Lessor) setting forth the nature and extent of insurance
maintained by Lessee in accordance with Section 13 and (2) a certificate from

     Lessor and its Funding Sources or their authorized representatives may (i)
enter, at its own risk, the premises of Lessee at reasonable times upon
reasonable advance notice in order to inspect the Equipment (subject to the

all documents and instruments in the possession of Lessee that are reasonably
necessary or appropriate for Lessor or such authorized representatives to
determine the truth and accuracy of any schedule, annex, exhibit or
representation delivered or made hereunder or compliance by Lessee with any of
the agreements herein contained and (ii) discuss the condition and performance
of the Equipment with the responsible officers of the Lessee, and Lessee agrees
to take such reasonable and customary steps as are appropriate to facilitate
such inspections and discussions. Lessor and its Funding Sources shall not incur
any liability or obligation for not making any such inspection or for not
conducting any such discussion. Notwithstanding the provisions of Section 18,
such inspections of the Equipment located in the Gulf of Mexico shall be at the
sole cost, risk and expense of Lessor and its Funding Sources and subject to
Lessee's discretion as operator to bar access to the Units of Equipment for
safety reasons. Such inspections of Equipment located in the Gulf of Mexico

perform any act required to be made or performed by it hereunder, Lessor, upon
notice to or demand upon Lessee but without waiving or releasing any obligation
or default, may (but shall be under no obligation to) at any time thereafter
make such payment or perform such act for the account and at the expense of
Lessee.  All payments and expenses (including, without limitation, reasonable
attorneys' fees and expenses) made or incurred by Lessor in connection with such
payment or performance shall be remitted by Lessee to Lessor upon its demand
therefor.

this Lease) require the consent, approval, authorization of any Person or
governmental authority, body or agency except any consent, approval or
authorization

not and will not contravene any provision of any law, rule, regulation, decree,
ruling, judgment, order or injunction currently applicable to or binding upon
Lessee, and (iii) do not and will not contravene, or result in the creation or
imposition of any Lien on any property of Lessee or on any Unit of Equipment

Equipment.

     (h)  To the best of Lessee's knowledge, after reasonable investigation, (i)
all facilities and property (including underlying groundwater) owned, leased, or
operated by Lessee have been, and continue to be, owned, leased or operated by
Lessee in material compliance with all Environmental Laws as they exist on the
date hereof such that any event or occurrence of non-compliance with any
Environmental Law, singly or in the aggregate, does not have, and may not
reasonably be expected to have, a material adverse effect on the financial
condition, operations, assets, business, properties or prospects of Lessee, (ii)
there have been no past, and there are no pending or threatened, claims,
complaints, notices or inquiries to, or requests for information received by,

liability under, any Environmental Law which has, or which may reasonably be
expected to have, a material adverse effect on the financial condition,
operations, assets, business, properties or prospects of Lessee, and (iii) no
environmental condition exists which would have a material adverse effect on the
financial condition, operations, assets, business, properties or prospects of
Lessee.

factual information hereafter furnished by or on behalf of Lessee or any to
Lessor will be, true and accurate in every material respect on the date as of
which such information is dated or certified and as of the date of execution and
delivery of this Lease by Lessor, and such information is not, or shall not be,
as the case may be, incomplete by omitting to state any material fact necessary
to make such information not misleading.

     (j)  Lessee will, after giving effect to the acquisition of each Unit of
Equipment by the Lessor and the leasing of such Equipment by

Minerals Management Service, U.S. Department of the Interior or any successor
thereto and Lessee will comply with the requirements of the affected oil and gas
leases and all permits, rights-of-way, easements, consents, certificates and
licenses affecting the Units of Equipment and the Reserves. Without limiting the
generality of the foregoing, all insurance and other evidence of financial
responsibility maintained by Lessee meets or exceeds all Federal, State and

     (m)  The execution and delivery of, and performance and compliance with,
this Lease and the acquisitions and ownership of the Equipment by Lessor do not

obtained by a Lessor as a result of Lessor's legal or regulatory status.

     (n)  Lessee is not engaged in the business of extending credit for the
purposes of purchasing or carrying margin stock, and no advances by Lessor to
Lessee pursuant to this Lease will be used for a purpose which violates, or
would be inconsistent with, Regulation G, U or X of the Board of Governors of
the Federal Reserve System or any successor thereto.  Terms for which meanings
are provided in Regulation G, U or X or any regulations substituted therefor, as
from time to time in effect, are used in this Section with such meanings.

     (o)  The Operating Agreements and other contracts identified on Schedule H
hereto constitute all of the material contracts relating to or affecting the
Units of Equipment and the exploration, development and production of the
Reserves, other than contracts relating to the acquisition, use, construction or
fabrication of the Equipment entered into with one or more Vendors and other
than contracts relating to the transportation or marketing of oil and gas.

Section 21.  Indemnification by Lessee.
             ------------------------- 

     Lessee shall pay, and shall protect, indemnify and save harmless Lessor and
its officers, directors, partners, employees and agents (individually an
"Indemnified Party" and collectively, the "Indemnified Parties") from and

causes of action, suits, costs and expenses (including, without limitation,
reasonable attorneys' fees and expenses), including liabilities, taxes, losses,
obligations, claims, damages, penalties, causes of action, suits, costs, and
expenses arising from their own negligence, and judgments of any nature,
irrespective of whether any such Indemnified Party is a party to the action for

Risks") arising from or relating to (i) Lessee's respective agreements or
obligations contained in this Lease or the Master Lease Agreement (including all
obligations in respect of payments or otherwise hereunder or thereunder), (ii)
Lessor's and its Funding Sources' ownership and leasing of any and all Units of
Equipment during the term of this Lease, (iii) all acts or omissions of Lessee
or any sublessee or bailee of any Unit of Equipment, (iv) any failure by Lessee
to comply with all govern mental rules and regulations applicable to the

enforcement thereof, (viii) any Imposition, Lien, Judgment, tax, or other
payment which Lessee is obligated to discharge or pay to any Person other than
Lessor, or (ix) any action or omission of Lessee pursuant to the Special Power
of Attorney, except to the extent that a court of competent jurisdiction in a
final judgment determines that an Indemnified Risk resulted from the gross
negligence or willful misconduct of such Indemnified Party and except that this
Section 21 shall not limit the effect of the proviso in Section 3(d) hereof. If
any claim, action, suit or proceeding arising from any of the foregoing is
brought against Lessor or any other Indemnified Party, Lessee will have the
right, at Lessee's expense, to resist and defend such action, suit or proceeding
or cause the same to be resisted and defended, provided, that (a) counsel
                                               --------------
designated by Lessee is reasonably acceptable to the Indemnified Party, (b)
Lessee will have acknowledged in writing that this Section 21 will cover any
Indemnified Risks in any such claim, action, suit or proceeding, (c) in the sole
determination of such Indemnified Party, Lessee has the financial ability to pay
such Indemnified Risks and (d) Lessee shall thereafter consult with the
Indemnified Party upon such party's request for consultation from time to time
with respect to such claim, action, suit or proceeding, but such Indemnified
Party shall be entitled (but not obligated) to participate jointly in such
defense, in which case (x) if all conditions

                                      36
<PAGE>
 
in clauses (a), (b), (c), and (d) of the foregoing proviso have been satisfied
(as determined by the Indemnified Party in its discretion), then such
Indemnified Party will be responsible for its own legal fees or other expenses,
if any, related to such defense incurred subsequent to the joint participation
by such party in such defense other than the reasonable costs of investigation,
or (y) if any condition in clause (a), (b), (c) or (d) of the foregoing proviso
has not been satisfied (as determined by the Indemnified Party in its
discretion), then Lessee will be responsible for the Indemnified Party's
reasonable legal fees and other expenses, if any, related to such defense
incurred subsequent to the joint participation by such Indemnified Party in such
defense, including the reasonable costs of investigation. If an Indemnified Risk
shall be fully covered by valid and collectible insurance provided pursuant to
Section 13 hereof, Lessee or its counsel shall have full power and authority to
litigate, compromise or settle such Risk; provided that Lessee or its counsel
shall not enter into any compromise or settlement of any non-monetary claims
without the Indemnified Party's prior written consent. The obligations of Lessee
under this Section 21 shall survive any termination of this Lease, in whole or
in part.

Section 22.  No Merger.
             --------- 

     There shall be no merger of this Lease or of the leasehold interest created
by this Lease with the absolute ownership interest in the Equipment by reason of
the fact that the same entity may acquire or own or hold, directly or indirectly
(a) this Lease or the leasehold interest created by this Lease or any interest
in this Lease or in such leasehold interest and (b) the absolute ownership or
any other interest in any Equipment, and no such merger shall occur unless and
until all entities having any interest in (i) this Lease or the leasehold
interest created by this Lease and (ii) the absolute ownership or other interest
in the Equipment shall join in an instrument effecting such merger and shall
duly record the same.

Section 23.  Notices.
             ------- 

          All notices, demands, instructions and other communications required

     To ask for, demand, collect, and recover, each in the name of Lessee, any
     and all sums that may be due on account of any damage that may have arisen

                            PARTICIPATION AGREEMENT
                            -----------------------



     This PARTICIPATION AGREEMENT ("Agreement") is entered into by and between
EP Operating Limited Partnership ("EPO"), by Enserch Exploration, Inc., its
Managing General Partner, 4849 Greenville Avenue, Suite 1200, Dallas, Texas
75206 and Mobil Producing Texas & New Mexico Inc. ("Mobil"), 1250 Poydras Plaza,
New Orleans, Louisiana 70113-1892.  EPO and Mobil collectively may be referred
to herein as "Parties" or individually as "Party".


                                    RECITALS
                                    --------

     EPO is the owner of an interest in certain Federal oil and gas leases
("Leases") located on the Outer Continental Shelf, Offshore Louisiana.  The
Leases are dedicated to a Federal Exploratory Unit for the exploration and
production of oil and gas ("Garden Banks 388 Unit" or "Unit").  The Leases and
the Garden Banks 388 Unit are more particularly described in Exhibit "A".  EPO's
exploration, development and production operations associated with the Unit may
be collectively referred to herein as the "Garden Banks 388 Project" or
"Project".

     Due to the magnitude of the anticipated risks and costs related to the
exploration and development operations in the Unit, the Parties deem it
necessary to join together under the terms of the Agreement, for the purpose of
sharing said risks and minimizing the individual expenses and investments
related to the proper exploration and development of the Unit.

     EPO and its predecessors in interest have drilled certain oil and gas wells
and installed certain equipment on the Leases.  These wells and the equipment
associated with these wells ("Wells and Equipment") are described in Exhibit
"B".

     EPO has proposed drilling an exploratory well ("GB 387 #3 Well") to test
for additional oil and gas reserves on the Leases.  In addition, both EPO and
Mobil have expressed an interest in conducting 3-D seismic exploration of the
Garden Banks 388 Unit and the surrounding area.

     EPO has designed and is in the process of constructing and installing a
deep water production system ("Production System") to develop and produce the
oil and gas reserves that may be located on the Leases.  The deep water
production system consists of a Floating Production and Drilling Facility, 24
Slot Template, Subsea Systems, Export and Gathering Pipelines and a Shallow
Water Processing Platform (collectively referred to as the "Production System").
The Production System is more particularly described in the Project Plan
documents ("Project Plan") identified in Exhibit "C".

     Mobil has expressed an interest in participating in the Garden Banks 388
Project.  EPO has offered to allow Mobil to acquire an interest in the Leases,
Unit, Wells and Equipment and
<PAGE>
 
Production System by: (1) acquiring a license to certain seismic data for the
benefit of EPO;  (2) by participating in the GB 387 #3 Well;  and (3) by
participating in the design, construction and installation of the Production
System.  Mobil's participation in the Garden Banks 388 Project shall be
conducted in accordance with this Agreement and the associated operating
agreements governing the conduct of operations on the Unit.

     In consideration of the foregoing,  EPO and Mobil agree as follows:


                                   PHASE ONE
                                   ---------

     The obligations of the Parties to participate in Phase One are effective
upon execution of this Agreement.


                               I.  SEISMIC SURVEY

     The Garden Banks 388 Unit is comprised of Garden Banks Blocks 388, 387, 386
and 344.  Garden Banks Blocks 342, 343, 345 and 389 directly offset the Unit.
These offsetting blocks are more particularly described in Exhibit "D"
("Offsetting Blocks").  EPO and Mobil desire to conduct 3-D seismic exploration
of the Unit and the Offsetting Blocks ("Seismic").  The Unit and the Offsetting
Blocks shall be referred to hereinafter as the "Joint Survey Area".

     Mobil has contracted with Western Geophysical Division of Western Atlas
International Inc. ("Western") to conduct a long cable 3-D seismic survey of the
Joint Survey Area and other lease blocks in the Gulf of Mexico ("Seismic
Survey"). A copy of the seismic contract dated May 25, 1994 is attached hereto
as Exhibit "E".  On or before August 15, 1994, Mobil shall cause the Seismic
Survey to be commenced in accordance with such contract.

     Mobil shall bear one hundred percent (100%) of the cost, risk and expense
of the Seismic Survey which is currently estimated to cost two million eight
hundred thirty-three thousand seven hundred sixty dollars ($2,833,760).
Additionally, because of derrick barge activity in the Unit during the Seismic
acquisition, Western has added an additional charge of five hundred ninety-four
thousand dollars ($594,000) to the cost of the Seismic because of the need to
run short lines.  Mobil shall pay 100% of this cost ("Seismic Short Lines").  In
addition to the cost of the Seismic Survey, Mobil shall pay 100% of the one
hundred forty thousand dollars ($140,000) cost of early processing so that the
data from the Seismic Survey shall have priority over the processing of other
data by Western ("Early Processing"). Upon completion of the Seismic Survey,
Mobil shall pay to Western one hundred percent (100%) of four hundred and five
thousand dollars ($405,000) to acquire a license ("License") to the data
generated by the Seismic Survey, insofar as such data covers and pertains to the
Joint Survey Area.  The License shall be acquired for the benefit of, and in the
name of, EPO and shall be in addition to the license that Mobil receives for its
own benefit from Western as a result of the Seismic Survey.  EPO

                                       2
<PAGE>
 
acknowledges and agrees that Mobil makes no representation or warranty as to the
accuracy or completeness of the data generated by the Seismic Survey.

     MOBIL HEREBY AGREES TO PROTECT, DEFEND, INDEMNIFY, AND HOLD EPO HARMLESS
FROM ANY AND ALL DEMANDS, CLAIMS, CAUSES OF ACTION, OR LAWSUITS ARISING FROM
MOBIL'S AND WESTERN'S ACTIVITIES PURSUANT TO THE SEISMIC SURVEY FOR THE DURATION
OF THE SURVEY.


                           II.  EXPLORATORY DRILLING

     EPO has been approved as Operator of the Garden Banks 388 Unit by the
Minerals Management Service of the U.S. Department of the Interior ("MMS").
Upon execution of this Agreement, EPO shall submit the documentation required by
the MMS to qualify Mobil as operator ("Operator") for the limited purpose of
drilling, testing and temporarily suspending operations on a new exploratory
well with two bottomhole objectives to be designated as the OCS-G 7485 #3 and
the OCS-G 10350 #1 (collectively referred to herein as the "GB 387 #3 Well" or
"Well") by the MMS.  Mobil's operation of the GB 387 #3 Well shall terminate and
EPO shall assume operations upon release of the rig that drilled the Well.  EPO
shall at all times be operator of the remainder of the Unit and the Production
System.

     The Parties shall, as soon as practicable but no later than, July 15, 1994,
execute a  Well Operating Agreement ("WOA").  Mobil shall be designated the
Operator of the GB 387 #3 Well in the WOA.  The WOA shall be incorporated by
reference in this Agreement.  In the event of a conflict between the WOA and
this Agreement, this Agreement shall control.

     Subject to the approval of Mobil as Operator by the MMS, on or before
September 15, 1994, Mobil shall commence or cause to be commenced drilling of
the GB 387 #3 Well.  The contracting of a rig capable of drilling the well shall
constitute the commencement of operations.  Operations shall be governed by the
WOA.

     The Well shall have a surface location 3,553' FNL and 2,821' FWL and a
bottomhole location at Total Depth of 4,569'' FNL and 1,981'' FWL of Garden
Banks Block 387.  The Well shall be drilled in accordance with the Well Plan
attached hereto as Exhibit "F".  The Well shall be drilled to a total depth of
12,000' TVD to test the 11,200' Sand amplitude anomaly ("Total Depth").  The
11,200' Sand amplitude anomaly is identified as the stratigraphic equivalent of
that certain formation which appears in the interval between 16,100' and 16,300'
on the IES/SFL log of the OCS-G 8232  #1 well located on Garden Banks Block 344.
Unless otherwise agreed to by the Parties, the Well shall be drilled by Mobil to
a depth of 12,000' TVD and not deeper.  (Notwithstanding the foregoing, if no
gravel pack flow test will be conducted, EPO may direct that the Well be drilled
deeper in accordance with Step 5 of the Well Plan.)

     Upon reaching Total Depth, Mobil shall conduct logging, coring and testing
operations (other than a gravel pack flow test) in accordance with the Well Plan
and the WOA.  After all

                                       3
<PAGE>
 
logging, coring and testing operations have been completed, the GB 387 #3 Well
shall be cased to Total Depth, in accordance with Step 5 of the Well Plan.

     If prior to reaching Total Depth, the GB 387 #3 Well encounters horizon(s)
which qualify the well as producible in paying quantities in accordance with 30
CFR 250.11 ("Producible Well"), after running casing in the hole Mobil may
conduct a gravel pack flow test of the potentially productive zones.  If a
gravel pack flow test is conducted, the Parties shall not conduct deeper
drilling operations in the Well.

     Mobil shall bear sixty percent (60%) and EPO shall bear forty percent (40%)
of all cost, risk and expense to reach Total Depth including, but not limited
to, the cost to drill, log, test (including gravel pack flow test), core and set
7" or 9 5/8ths" casing to Total Depth and the cost to temporarily suspend
operations on the Well.  Mobil shall pay sixty percent (60%) and EPO shall pay
forty percent (40%) of all sidetracking costs conducted pursuant to the Well
Plan or otherwise mutually agreed upon by the Parties.  EPO shall be credited
with all hydrocarbons produced during the gravel pack flow test, if any, and
forty percent (40%) of the net proceeds from the sale of the produced
hydrocarbons shall be subtracted from the Work Commitment (as hereinafter
defined).

     If operations are proposed to be conducted that have not been agreed upon
in the Well Plan, and the non-proposing Party elects to participate, Mobil shall
bear sixty percent (60%) and EPO shall bear forty percent (40%) of the cost of
such operations.  If the non-proposing Party elects not to participate in such
operation, the proposing party may conduct such operation at its sole cost, risk
and expense ("Sole Risk Operation") subject to the terms provided hereunder in
the section titled "Work Commitment".  Any well information acquired as a result
of a Sole Risk Operation shall be disclosed to the non-participating Party at
the time of its acquisition.  Sole Risk Operations do not include the option of
deepening the well beyond Total Depth other than to extend the depth at which
intermediate casing may be set in preparation for deepening as described in Step
5 of the Well Plan.

     If upon reaching Total Depth the GB 387 #3 Well does not qualify as a
Producible Well, operations shall be temporarily suspended so that the well may
be re-entered and deepened at a later date or the Well shall be plugged and
abandoned, at EPO's option.  The rig shall be released after temporary
suspension operations have been completed or upon plugging and abandonment,
whichever is applicable.  After March 1, 1995, EPO shall have the right to
propose to Mobil deepening the Well ("Deepening").  The Deepening shall be
required to be commenced on or before December 31, 1995.  If Mobil elects to
participate in the Production System as described in Phase Two below, Mobil may
elect to participate or not participate in such Deepening pursuant to the Unit
Operating Agreement (as hereinafter defined).  In either case, Mobil shall pay
100% of the cost to mobilize and demobilize the rig that conducts the Deepening
operations up to a total cost of $500,000.  This cost shall not be credited
against Mobil's Work Commitment.

                                       4
<PAGE>
 
                                 III.  SUBSTITUTE WELL

     If prior to the completion of the operations described above for the GB 387
#3 Well, Mobil encounters downhole mechanical conditions, which in the opinion
of a reasonably prudent operator under the same or similar conditions would
render further drilling or other operations impracticable or hazardous, and such
conditions prevent the completion of the operations described above, Mobil shall
commence a "Substitute Well". The actual drilling of the Substitute Well shall
be commenced within thirty (30) days after release of the drilling rig used for
the GB 387 #3 Well subject to rig availability. The Substitute Well shall be
drilled, tested and temporarily suspended on the same terms as are provided for
herein for the GB 387 #3 Well. The Substitute Well shall be deemed to be the GB
387 #3 Well for purposes of this Agreement.

     If Mobil encounters impenetrable substances or other geologic conditions,
which in the opinion of a reasonably prudent operator under the same or similar
conditions would render further drilling or other operations impracticable or
hazardous, and such conditions prevent the completion of the operations
described above, Mobil shall be released from the obligation to drill the GB 387
#3 Well, however, Mobil shall forfeit the opportunity to participate in Phase
Two as described herein. Mobil shall remain obligated to perform in accordance
with the other terms and conditions set forth herein.


                     IV.  PROJECT COORDINATOR AND STAFFING
Project Coordinator and Mobil Observer(s)
- -----------------------------------------

     During Phase One, EPO will assist Mobil in its assessment of the Garden
Banks 388 Project. EPO shall provide sufficient office space at its Houston
Project Office to accommodate an individual to be designated Mobil's Project
Coordinator ("Project Coordinator") and, as available, additional office space
for other Mobil employees ("Mobil Observer(s)"). EPO shall provide basic office
furniture and a telephone for the Project Coordinator and each Mobil Observer
assigned to the Project. Mobil shall be responsible for providing any other
equipment required, including computers. Access to copying facilities shall be
provided. EPO shall not be required to provide secretarial support. The Project
Coordinator and Mobil Observer(s) shall have access to the Project Office during
normal business hours and at such other times as may be necessary due to the
occurrence of critical events.

     The Mobil Observer(s) shall have reasonable access to members of EPO's
project staff in order to observe and evaluate the progress of operations. Both
EPO and Mobil shall encourage the free flow of information between the project
staff and the Project Coordinator. The Project Coordinator may participate in
meetings in which key decisions regarding the Project are discussed and the
Project Coordinator may contribute information and opinions in such meetings,
however, decision making shall be the sole responsibility of EPO's project
staff. The Project Coordinator may attend meetings between representatives of
EPO and the MMS or

                                       5
<PAGE>
 
other regulatory agencies as an observer.  Any questions regarding access,
responsibilities or decision making shall be brought to the attention of, and
resolved by, EPO's Project Director in consultation with the Project
Coordinator.

     Mobil shall have reasonable access during normal business hours to records
relating to the Unit in EPO's possession in Houston and Dallas, including
contract files, lease files, well files and financing documents. Insofar as EPO
has the ability to do so, EPO shall assist Mobil in acquiring access during
normal business hours to facilities where the components of the Production
System are being fabricated. EPO shall provide Mobil a monthly report regarding
commitments, expenditures, and estimated final costs of the Units of Leased
Property funded under the Master Lease Financing (as hereinafter defined) and
other development cost authorizations.

     Other than the cost of office space, furniture and telephone service
described above, Mobil shall bear one hundred percent (100%) of the cost of the
Project Coordinator's and the Mobil Observer(s)' evaluation of the Project and
all access to the facilities of EPO, its contractors or vendors shall be at
Mobil's sole cost, risk and expense. Mobil's costs shall not be deducted from
the Work Commitment.

Seconded Staff
- --------------

     Mobil shall be invited by EPO to participate in remaining engineering or
operational activities where Mobil can add value to the project in either Phase
One or Phase Two. This may occur in circumstances where Mobil employee(s) have
particular expertise in an area. If Mobil employee(s) are assigned to EPO's
project staff as technical employees of the Project, EPO and Mobil shall enter
into a contract for the services of such employee(s) prior to such employee(s)'
dedication to the Project ("Contract"). Prior to making the Participation
Election, Mobil shall periodically invoice EPO for sixty percent (60%) of the
reasonable salaries, benefits and expenses of such employee(s). If Mobil makes
the Participation Election, the reasonable salaries, benefits, and expenses of
such employee(s) shall be charged to the joint account pursuant to the Unit
Operating Agreement (as hereinafter defined). If Mobil fails to make the
Participation Election, Mobil shall invoice EPO for 100% of all reasonable
salaries, benefits, and expenses of such employee(s) under contract. Such
employee(s) shall remain dedicated to the Project through completion of the
Project Plan unless otherwise provided in the Contract.


                                   PHASE TWO
                                   ---------

     The obligations of the Parties to participate in Phase Two are contingent
upon the Participation Election of Mobil.

                                       6
<PAGE>
 
                          V.  PARTICIPATION ELECTION

     On or before March 1, 1995, Mobil may elect either to participate for a
forty percent (40%) interest in the design, construction and installation of the
Production System or to withdraw from the project. Such election shall be made
in writing in accordance with the notice provisions contained herein. A failure
timely to make the required election shall be deemed an election not to
participate. Such election is contingent upon the receipt of approval by the
requisite level(s) of Mobil's management, none of which shall have any
obligation to be reasonable or not be arbitrary, and upon resolution to Mobil's
satisfaction of all outstanding issues concerning EPO's and/or Mobil's financing
of the Production System ("Participation Election").

     If Mobil fails to make the Participation Election, Mobil shall earn no
interest in the GB 387 #3 Well, the Leases, the Production System or the Unit.
Mobil shall bear no additional costs other than costs associated with its
assumption of the cost, risk and expense of the operations in which it
participated and Mobil shall not be obligated for any future GB 387 #3 Well
abandonment and plugging costs (other than the mobilization and demobilization
costs associated with Deepening operations described above) that are incurred
after March 1, 1995.

     If Mobil makes the Participation Election, EPO shall deliver to Mobil an
accounting for Mobil's forty percent (40%) of the costs incurred as of the last
day of the month prior to the date of the Participation Election in designing,
constructing and installing the Production System. The costs that shall be
included in the accounting are the costs EPO incurs that are funded pursuant to
the Master Lease Financing plus any other costs that are directly attributable
to the design, construction or installation of the Production System including
the cost of EPO's project office and project management. If Mobil elects to
participate in the Master Lease Financing, the accounting shall establish the
amount of Mobil's obligation to the Banks (as hereinafter defined) through the
closing date of the accounting. If Mobil elects not to participate in the Master
Lease Financing, the accounting shall serve as an invoice to Mobil that shall be
payable by Mobil to the Banks within thirty (30) days after its receipt. The
Banks shall be instructed by EPO and Mobil to apply Mobil's payment at the next
interest payment date to the outstanding principal balance under the Master
Lease Financing. Regardless of whether Mobil elects to participate in the Master
Lease Financing, if the cost of the Production System exceeds the amount funded
pursuant to the Master Lease Financing, Mobil shall pay forty percent (40%) of
such costs to EPO at the time of its Participation Election. Thereafter, Mobil
shall pay to EPO as Operator, its proportionate share of current joint interest
billing obligations pursuant to the UOA.


                          VI.  MASTER LEASE FINANCING

     EPO, the Garden Banks Trust and Chase Manhattan Bank, N.A. have entered
into a Master Lease Agreement and a Funding Agreement, each of which is dated
effective September 30, 1992. The Master Lease Agreement and Funding Agreement
are collectively referred to

                                       7
<PAGE>
 
herein as the Master Lease Financing.  The defined term Master Lease Financing
includes the various associated contracts which establish the lease structure
and which are referred to in the Master Lease Agreement and Funding Agreement.
A copy has been provided to Mobil prior to execution of this Agreement.

     Pursuant to the Master Lease Financing, a syndicate of banks ("Banks") has
agreed to purchase certain Notes and Certificates in the amount of $235,000,000.
The proceeds from the sale of the Notes and Certificates are being used to fund
the design, construction and installation of the Production System. Pursuant to
the Master Lease Financing, the Garden Banks Trust is the owner of the
Production System. The Garden Banks Trust, as Lessor, has leased the Production
System to EPO. EPO has the right to quiet enjoyment of the Production System
during the term of the Master Lease Financing. The Master Lease Financing
establishes the Chase Manhattan Bank, N.A. as the Agent of the Garden Banks
Trust for the purposes of managing the financing transaction.

     If Mobil elects to participate in the Production System, Mobil may
participate in the Master Lease Financing with EPO to the extent of its forty
percent (40%) interest as a co-lessee pursuant to Section 21 of the Master
Lease. An election by Mobil to participate as a co-lessee shall be subject to
approval by the Banks. Mobil shall provide notice to EPO of its desire to
participate in the financing no later than the date upon which it makes its
Participation Election.

     Alternatively, Mobil may elect to internally fund or otherwise finance its
share of the Production System costs outside of the Master Lease Financing in
which case Mobil may require, subject to approval by the Banks, a collateral
sharing agreement with the Banks and/or other financial institutions, along the
lines of the indicative Term Sheet "B" submitted by Chase Manhattan Bank, N.A.
on June 30, 1994, as attached hereto as Exhibit "J". EPO shall, if requested by
Mobil, explore other financing options with Mobil, including a co-lessor option
which may also require a collateral sharing agreement with the Banks and/or
other financial institutions. All costs and expenses incurred by EPO in
terminating the Master Lease Financing (unless the Master Lease Financing is
terminated in order to arrange mutually acceptable financing, in which case such
termination costs shall be paid sixty (60%) by EPO and forty percent (40%) by
Mobil) and in negotiating and entering into alternatives to the Master Lease
Financing structure shall be borne one hundred percent (100%) by Mobil and shall
not be credited against the Work Commitment except that Mobil shall not be
responsible for any prepayment penalties which relate to any termination or
paydown of the Master Lease Financing, in whole or in part, except those costs
related to yield maintenance.

     IF EITHER PARTY DEFAULTS OR CAUSES A DEFAULT UNDER THE MASTER LEASE
FINANCING OR ANY OTHER FINANCING PROGRAM FOR THE PRODUCTION SYSTEM, THE
DEFAULTING PARTY, ITS GENERAL PARTNER, PARENT AND\OR SUBSIDIARIES SHALL PROTECT,
DEFEND, INDEMNIFY, AND HOLD THE NON-DEFAULTING PARTY HARMLESS FROM ANY AND ALL
DEMANDS, CLAIMS, CAUSES OF ACTION, OR LAWSUITS ARISING FROM THE DEFAULTING
PARTY'S PERFORMANCE OR NON-PERFORMANCE OF ITS

                                       8
<PAGE>
 
OBLIGATIONS HEREUNDER, OR ARISING FROM THE DEFAULTING PARTY'S FAILURE TO COMPLY
WITH ANY EXPRESS OR IMPLIED COVENANT OF THE FINANCING DOCUMENTS, OR ARISING OUT
OF ACTS OF THE DEFAULTING PARTY WHICH CAUSE THE LENDING INSTITUTION IN THE
AFFECTED FINANCING PROGRAM TO EXERCISE ITS REMEDIES UNDER SUCH FINANCING
PROGRAM, AND THE DEFAULTING PARTY SHALL PAY ALL OF THE NON-DEFAULTING PARTY'S
EXPENSES AND ATTORNEY'S FEES IF THE DEFAULTING PARTY FAILS TO DEFEND OR IF IT IS
NECESSARY TO BRING SUIT TO ENFORCE THIS INDEMNITY PROVISION.


                               VII.  ASSIGNMENT

     If Mobil makes the Participation Election and otherwise fulfills its
obligations pursuant to this Agreement, within 30 days following payment by
Mobil of its share of project costs as described in the preceding sections, EPO
shall assign to Mobil an undivided forty percent (40%) interest in: (1) the GB
387 #3 Well; and, (2) all existing Wells and Equipment on the Unit; and, (3) the
Garden Banks 388 Unit; and, (4) an undivided forty percent (40%) record title
interest in the Leases; and, (5) an undivided forty percent (40%) of EPO's
interest in any additional leases added to the Unit prior to Mobil's
Participation Election (collectively "Assigned Premises"). (If Mobil owns an
interest in leases added to the Unit prior to Mobil's Participation Election,
the assignment from EPO shall be reduced so that the resulting ownership ratio
shall be sixty percent (60%) EPO and forty percent (40%) Mobil). Mobil shall
bear its proportionate share of an outstanding 2.59489% of 8/8ths overriding
royalty burdening the Leases in favor of EPO's predecessors in title and its
proportionate share of any overriding royalties or other burdens created by
EPO's predecessors in title to leases assigned to Mobil that lie outside the
Unit.

     The Assignment and Bill of Sale which shall convey title to the Assigned
Premises, both real and personal, moveable and immoveable, to Mobil shall be
substantially in the form of Exhibit "G".  Upon execution, it shall be recorded
by EPO in the three upland parishes that are adjacent to the Unit and it shall
be filed by EPO with the Minerals Management Service of the U.S. Department of
the Interior.


                            VIII.  WORK COMMITMENT

     If Mobil elects to participate by making the Participation Election, Mobil
shall perform a $25,000,000 work commitment in favor of EPO ("Work Commitment").

     At the time of its Participation Election, Mobil shall have paid one
hundred percent (100%) of the cost of EPO's License to the data from the Seismic
Survey, one hundred percent (100%) of the Early Processing fee, one hundred
percent (100%) of the Seismic Short Lines and sixty percent (60%) of the costs
of the GB 387 #3 Well, and Mobil may have undertaken other

                                       9
<PAGE>
 
operations including drilling, testing and temporarily suspending a Substitute
Well.  A total of $1,083,000 for EPO's License, the Early Processing fee, and
Seismic Short Line cost, plus all other actual costs of operations attributable
to the Project in excess of Mobil's forty percent (40%) interest in the Garden
Banks 388 Project shall be credited against the Work Commitment.  The Work
Commitment shall be increased by the amount of all costs of operations including
the drilling, testing, and completion of wells on the Unit, and lease
acquisition costs, borne by EPO after the spud date of the GB 387 #3 Well,
insofar as such costs exceed EPO's sixty percent (60%) interest in the project.
(Notwithstanding the foregoing, seven subsea spool tree assemblies and three
satellite well flow spools and their associated connector systems may be
acquired by EPO for future well completions on the Unit prior to the spud date
of the GB 387 #3 Well.  These items are not currently included in the Master
Lease Financing.  At the time of its Participation Election, EPO shall invoice
Mobil for one hundred percent (100%) of the cost of this completion equipment.
Mobil shall make payment to EPO within 30 days of receipt of said invoice.  Upon
payment, Mobil's Work Commitment shall be credited with sixty percent (60%) of
such payment.   No payment by Mobil will be due for this equipment if Mobil does
not elect to participate.)  After March 1, 1995, Mobil shall pay one hundred
percent (100%) of the cost to drill and complete new wells and the cost to
complete existing wells.  Sixty percent (60%) of such expenditures shall be
credited against the Work Commitment. When the Work Commitment is reduced to
zero, Mobil shall be obligated to bear only its proportionate share of future
costs pursuant to the Unit Operating Agreement.

     If a Sole Risk Operation is conducted by Mobil in the GB 387 #3 Well and
Mobil makes the Participation Election, the Work Commitment shall be reduced by
sixty percent (60%) of the cost of the Sole Risk Operation. If a Sole Risk
Operation is conducted by EPO in the GB 387 #3 Well and Mobil makes the
Participation Election, the Work Commitment shall be increased by forty percent
(40%) of the cost of the Sole Risk Operation.

     Within fifteen (15) business days after the close of each quarter,
beginning April 1, 1995, EPO will provide a status accounting of the remaining
Work Commitment balance owed by Mobil to EPO as of the close of the quarter.
Included in the status report will be the opening balance owed to EPO as of the
last report, a summary list of credits or debits to the Work Commitment and the
current balance owed as of the closing date of the report.

     If on July 1, 1997, Mobil has not completed its Work Commitment, it shall
on that date pay the outstanding balance to EPO in cash. After such a payment,
Mobil shall be obligated to bear only its proportionate share of costs pursuant
to the UOA.


                         IX.  UNIT OPERATING AGREEMENT

     After execution of this Agreement, the Parties shall enter into
negotiations regarding the contents of a Unit Operating Agreement ("UOA") that
will govern operations conducted on the Garden Banks 388 Unit if, and when,
Mobil makes the Participation Election. EPO shall be designated Operator under
the UOA.

                                       10
<PAGE>
 
                              X.  UNIT AGREEMENT

     The Minerals Management Service of the United States Department of the
Interior has approved formation of the Garden Banks 388 Unit. Such approval was
effective January 1, 1991, and assigned Unit Agreement No. 754391006. Upon
receipt of the Assignments provided for herein, Mobil shall execute and deliver
to the MMS a ratification of the Unit Agreement for the Garden Banks 388 Unit
and a Designation of Operator form designating EPO as Operator of the Unit.


                              GENERAL PROVISIONS

described in Articles I., II., III. and IV. herein. EPO hereby agrees to
protect, indemnify and hold Mobil harmless from any and all demands, claims,
causes of actions or lawsuits arising from EPO's activities prior to Mobil's
Participation Election except that prior to Mobil's Participation Election and
subject to the limitations on liability contained in the WOA, Mobil shall bear
that portion of the cost, risk, expense and liability associated with each
operation conducted on the GB 387 #3 Well in proportion to the percentage cost
assumed by Mobil for that operation. Mobil's Project Coordinator and the Mobil
Observer(s) shall at all times remain Mobil employees and the costs of such
employees shall not be charged to the Project.

          by EPO as contemplated hereunder.

     (c)  This Agreement, and the execution and delivery hereof by EPO, do not,
          and the consummation of the transaction contemplated hereunder will
          not, violate any provision of, or constitute a default under the
          partnership agreement establishing EP Operating Limited Partnership as
          a Limited Partnership or any law or regulation to which EPO is
          subject, or any provision of any indenture, mortgage, lien, lease,
          agreement, instrument, order, arbitration award, judgment, or decree
          to which EPO is a party or by which EPO or any of its assets or
          properties is bound.  Enserch Exploration, Inc. is the Managing
          General Partner of EP Operating Limited Partnership.

     (d)  EPO has not incurred any liability, contingent or otherwise, for
          brokers' or finders' fees relating to the transaction contemplated
          hereunder for which EPO or Mobil shall have any responsibility
          whatsoever.

     (e)  EPO has the right to assign the Assigned Premises on and from the date
          of this Agreement.  All requisite third party consents and approvals,
          including, without limitation, any preferential rights of purchase,
          any restrictions on sale, assignment, or transfer of the Assigned
          Premises, and any necessary governmental consents or approvals (except
          those governmental consents or approvals customarily obtained after an
          Assignment is made) have been secured by EPO.

     (f)  To the best of EPO's knowledge, information and belief, EPO has
          conducted its ownership of the Assigned Premises in compliance with
          all applicable federal, state, or local laws, codes or ordinances,
          rules and regulations, including those relating to the protection of
          the environment and in compliance with all material contracts, leases
          and permits.

     (g)  To the best of EPO's knowledge, information and belief, there are no
          pending claims, lawsuits, administrative proceedings, or governmental
          investigations or inquiries involving the Assigned Premises, including
          notices of violation from the EPA, and/or state and local
          environmental agencies except those claims, lawsuits, administrative
          proceedings, and governmental investigations and inquiries that EPO
          has disclosed to Mobil in writing which are listed in the Exhibits
          hereto.

     (h)  If EPO assigns the Assigned Premises to Mobil, such Assignment shall

          (except lessor's royalty), except as may be disclosed in this
          Agreement.

          production from any part of the Assigned Premises in which any third
          party is granted a call on EPO's interest in oil and/or gas production
          or the right to purchase such oil and/or gas for a period in excess of
          thirty (30) days.  EPO has contracts in place with Sea Robin Pipeline
          Company to transport gas produced from the Unit.

     (j)  To the best of EPO's knowledge, information and belief, no "Adverse
          Environmental Condition" exists with respect to the Assigned Premises
          except those disclosed in the Exhibits hereto.  For purposes of the
          agreement, an "Adverse Environmental Condition" is defined as any
          contamination or condition that is the result of any discharge,
          release, disposal, production, storage or treatment on or in the

          from the Assigned Premises to any other land or body of water,

Four elections are designated during the well plan:
1.   Elect whether to install an 11 3/4" casing string or 9 5/8".
2.   Elect to install the production casing string.
3.   Elect the zone to be the Primary Completion.
4.   Elect whether to complete a second interval and flow test it.

All intervals will be evaluated with MWD and if found hydrocarbon bearing,
formation evaluations with electric wire line logs will be performed.
Additional operations to obtain RFT pressure and fluid samples and SWC's will be
designed based on the results of the electric logging.

Accommodations for two Enserch employees will be made available on the drilling
rig at all times.  Additional Enserch employees may be accommodated on the rig
as space permits and, if space is not available, such additional employees may
be present on the rig on a day trip basis.
<PAGE>
 
Mobil will install a real time drilling data acquisition system at Enserch's
office in Dallas, Texas for the duration of the drilling operations.

Fluid sample acquisition, transfer, transport and analysis will be performed
using a Mobil prescribed procedure which is not elaborated in detail in this
Exhibit.

The DST program details and durations will be defined as a result of the
formation evaluation and the zone selection.  The flow test(s) will not exceed a
10 day flow duration each.


Step 1 - 7,600' Sand
The well will be drilled vertically to a depth sufficient to set 13 3/8" casing.
A deviated hole will be drilled to the 7,600' sand using a MWD tool assembly.

7,600' Sand Evaluation Program
The open hole formation interval will be evaluated with MWD and wire line
formation tests to determine the reservoir pressure, pressure gradients and to
obtain fluid samples.  Side wall cores will be obtained.  If wire line
operations are not feasible, the evaluation tools may be run on drill pipe.

Electric logs will be run across the interval only if the MWD results indicate
the presence of hydrocarbons and the hole conditions permit.

In the Event of the 7,600' Sand Being Non-productive
In the event the 7,600' sand is wet, Mobil shall have the option, in its sole
discretion to cancel the evaluation program described in the previous paragraph.
The well plan will continue with "Step 2".

In the event of the 7,600' sand being potentially productive the well plan will
continue with "Step 2".


Step 2 - 7,600' Sand Side Track #1
The open hole section drilled in "Step 1" will be abandoned and the well side
tracked to the 7,600' S/T location in a vertical hole.  A MWD tool in a
configuration which will provide the formation evaluation in close proximity to
the bit will be used.

7,600' Sand S/T Evaluation Program
After determination that the 7,600' sand has been penetrated, a Baker Hydrolift
coring assembly will be run and coring operations will commence until the base
of 7,600' sand has been reached or on-site Mobil and Enserch experts determine
that coring operations should be stopped.

An electric logging program will be run across the interval.

                                       2
<PAGE>
 
The 7,600' sand interval will be evaluated with wire line formation tests to
determine the reservoir pressure, pressure gradients and to obtain fluid
samples.  Side wall cores will be obtained.  If wire line operations are not
feasible, the evaluation tools may be run on drill pipe.

In the Event of the 7,600' Sand Side Track Being Non-productive
In the event the MWD results obtained upon penetration of the 7,600' Sand
indicate this interval to be wet, the coring operations will not be conducted.
The 7,600' Sand electric logging program shall  be conducted, unless the parties
mutually agree otherwise based on the MWD results.   The well plan will continue
with "Step 3".


Step 3 - Casing Program, 11 3/4" String Election
If after evaluation of the 7,600' Sand results, Mobil is unable to commit to a
gravel pack flow test or if adverse hole conditions are present, Mobil shall set
11 3/4" casing at the proper depth.  It is anticipated that if the 7,600' sand
is productive and the pressure regimes are not excessive, the 11 3/4" casing
string will not be installed and a 9 5/8" casing string will be installed at the
proper depth.


Step 4 - 9,800' Sand & 11,200' Sand Drilling
The well will be drilled using the MWD assembly described in "Step 2" to the
9,800' and 11,200' sand locations.  Conventional core samples will be obtained
in each as described below.

9,800' and 11,200' Sand Evaluation Programs
As the MWD response indicates each sand is penetrated, three trips will be made
with a Baker Hydrolift coring assembly using a thirty foot long core barrel
with aluminum inner sleeve in each trip.

The MWD assembly will be used to drill through each interval.

An electric logging program will be run across each interval.

The intervals will be evaluated with wire line formation tests to determine the
reservoir pressure, pressure gradients and to obtain fluid samples.  Side wall
cores will be obtained.  If wire line operations are not feasible, the
evaluation tools may be run on drill pipe.

In the Event of 9,800' or 11,200' Sand Being Non-productive
In the event that either sand is determined to be wet, the coring operations
will not be conducted.  The 9,800' and 11,200' Sand electric logging program
shall  be conducted unless the parties mutually agree otherwise based upon the
MWD results.  The well plan will continue with "Step 5".

                                       3
<PAGE>
 
Step 5 - Production Casing Election
Upon completion of evaluations in "Step 4", Mobil shall notify EPO whether it
will conduct a gravel pack flow test of the 9,800' Sand or the 11,200' Sand.  If
11 3/4" casing was set in Step #3 above and if Mobil will conduct any gravel
pack flow test in the well, Mobil shall have the option, in its sole discretion,
to run 9 5/8" casing or 7" production casing to Total Depth.  If Mobil will not
conduct any gravel pack flow test in the well, EPO shall have the option, in its
sole discretion, to direct that Mobil run 9 5/8" casing, 7" casing or no casing
to Total Depth.  In addition, if no gravel pack flow test will be conducted, EPO
may direct that Mobil continue drilling the well deeper until such time as the
mud weight reaches 1/2 PPG less than the previous casing shoe test.  The purpose
of such deeper drilling shall be to extend the depth at which intermediate
casing may be set in preparation for Deepening operations to be conducted at a
later date. Such deeper drilling shall be conducted as a Sole Risk Operation for
EPO. Mobil shall remain obligated for its share of casing costs to 12,000'.

Prior to setting casing, if hole conditions permit, 200' of "rat hole" will be
drilled below the deepest known hydrocarbon interval.


Step 6 - Completion and Flow Tests
If the MWD indicates the presence of hydrocarbons in the well, Mobil may elect
that at least one zone but no more than two will be completed and flow tested.
An election will be made whether to complete and flow a second interval.  Mobil
will designate which zone is the "Primary Completion".

If a second zone is recommended for completion and flow testing by Mobil or
Enserch, the other party may elect not to participate.  In this event, the cost
of the second zone operations will be Sole Risk Operations and added or
subtracted from the Mobil Work Commitment according to the Participation
Agreement.  Both parties will fund the costs of the Primary Completion and its
flow test.  Any mob or de-mob and operational setup charges for the completion
and flow test operations will be carried by the Primary Completion operation and
not factored for inclusion in the charges for the second interval completion and
flow testing.

The cost of the second completion and flow test will not be included in the
initial AFE.

The completion(s) will be gravel packed with 3 1/2" i.d. production tubing if
the casing program permits.

The flow test(s) will not exceed a 10 day flow duration each.


Step 7 - TP&A Well
The well will be TP&A'ed upon completion of the flow test(s).  If no gravel pack
flow tests are conducted, EPO may, it its sole discretion, direct that Mobil
permanently plug and abandon the well.

1.   GENERAL PROVISIONS

     1.1  Designation of Documents. This exhibit is referred to in, and is part
     of, that Agreement identified above and, if so provided, a part of any
     agreement to which the Agreement is an exhibit. Such agreement(s)
     (including all exhibits thereto, other than this exhibit) shall be
     hereinafter referred to as the "Agreement"; and this exhibit is hereinafter
     referred to as the "Exhibit." Except as may be otherwise provided in this
     Exhibit, terms defined and used in the Agreement shall have the same
     meaning when used herein.
 
     1.2  Relationship of the Parties. The parties to this Agreement shall be
     hereinafter referred to as "Party" or collectively as "Parties." The
     Parties understand and agree that the arrangement and undertakings
     evidenced by the Agreement result in a partnership for purposes of Federal
     income taxation and certain State income tax laws which incorporate or
     follow Federal income tax principles as to tax partnerships. Such
     partnership for tax purposes is hereinafter referred to as the
     "Partnership." For every other purpose of the Agreement the Parties
     understand and agree that: (i) their legal relationship to each other under
     applicable State law with respect to all property subject to the Agreement
     is one of tenants in common, or undivided interest owners, or lessee(s)-
     sublessee(s), and not a partnership; (ii) that the inabilities of the
     Parties shall be several and not joint or collective; and (iii) that each
     Party shall be responsible solely for its obligations.

     1.3  Priority of Provisions of this Exhibit. If there is a conflict or
     inconsistency, whether direct or indirect, actual or apparent, between the
     terms and conditions of this Exhibit and the terms and conditions of the
     Agreement, or any other exhibit or any part thereof, the terms and
     conditions of this Exhibit shall govern and control.

     1.4  Survivorship.

          1.4.1 Any termination of the Agreement shall not affect the
          continuing application of the Partnership provisions for termination
          and liquidation.

          1.4.2 Any termination of the Agreement shall not affect the continuing
          application of the Partnership provisions for the resolution of all
          matters regarding Federal and State income reporting.
<PAGE>
 
          1.4.3 These Partnership provisions shall inure to the benefit of, and
          be binding upon, the Parties hereto and their successors and assigns.

     1.5  Term.  The effective date of the Partnership shall be the effective

     effect from and after such date, until termination and liquidation.

2.   INCOME TAX COMPLIANCE AND CAPITAL ACCOUNTS

     2.1  Tax Returns. The Tax Matters Partner ("TMP"), as designated in (S)
     3.1, shall prepare and file all required Federal and State partnership
     income tax returns. In preparing such returns the TMP shall use its best
     efforts and in doing so shall incur no liability to any other Party. Not
     less than thirty (30) days prior to the return due date (including
     extensions) the TMP shall submit to each Party for review a copy of the
     return as proposed.

     2.2  Fair Market Value Capital Accounts. The TMP shall establish and
     maintain for each Party fair market value ("FMV") capital accounts and tax
     basis capital accounts. Upon request, the TMP shall submit to each Party
     along with a copy of any proposed partnership income tax return an
     accounting of such Party's FMV capital accounts as of the end of the return
     period.

     2.3  Information Requests. Each Party agrees to furnish to the TMP not
     later than sixty (60) days before the return due date (including
     extensions) such information relating to the operations conducted under
     this Agreement as may be required for the proper preparation of such
     returns and capital accounts.

3.   TAX MATTERS PARTNER

     3.1  Tax Matters Partner. The Operator is designated TMP as defined in
     Internal Revenue Code (the "Code") (S) 6231 (a)(7). In the event of any
     change in the TMP, the Party serving as TMP at the beginning of a given
     taxable year shall continue as TMP with respect to all matters concerning
     such year. The TMP and other Parties shall use their best efforts to comply
     with responsibilities outlined in this section and Code (S)(S) 6222 through
     6233 and 6050K (and the Treasury Regulations thereunder) and in doing so
     shall incur no liability to any other Party. Notwithstanding the TMP's
     obligation to use its best efforts in the fulfillment of its
     responsibilities, the TMP shall not be required to incur any expenses for
     the preparation for, or pursuance of, administrative or judicial
     proceedings, unless the Parties agree on a method for sharing such
     expenses.

     3.2   Information Request by the TMP. The Parties shall furnish the TMP,
     within two weeks from the receipt of the request, the information
     (including information specified in Code  (S)(S) 6230(e) on partner
     identification and 6050K for transfers of partnership

                                       2
<PAGE>
 
     interests) the TMP may reasonably request to comply with the requirements
     on furnishing information to the Internal Revenue Service.

     3.3  TMP Agreements with IRS.

          3.3.1  The TMP shall not agree to any extension of the statute of
          limitations for making assessments on behalf of the Partnership
          without first obtaining the written consent of all Parties. The TMP
          shall not bind any other Party to a settlement agreement in tax audits
          without obtaining the written concurrence of any such Party.

          3.3.2  Any other Party who enters in a settlement agreement with the
          Secretary of the Treasury with respect to any partnership items, as
          defined in Code (S) 6231(a)(3), shall notify the other Parties of the
          terms within ninety (90) days from the date of such settlement.

     3.4  Inconsistent Treatment of Partnership Items.  If any Party intends to
     file a notice of inconsistent treatment under Code (S) 6222(b), such
     Party shall, prior to the filing of such notice, notify the TMP of the
     (actual or potential) inconsistency of the Party's intended treatment of a
     partnership item with the treatment of that item by the Partnership. Within
     one week of receipt the TMP shall remit copies  of such notification to the
     other Parties. If an inconsistency notice is filed solely because a Party
     has not received a Schedule K-1 in time for the filing of its income tax
     return, the TMP need not be notified.

     3.5  Request for Administrative Adjustment. No Party shall file pursuant to
     Code (S) 6227 a request for an administrative adjustment of partnership
     items without first notifying all other parties. If all other Parties agree
     with the requested adjustment. the TMP shall file the request on behalf of
     the Partnership. If unanimous consent is not obtained within thirty (30)
     days from such notice, or within the period required to timely file the
     request, if shorter, any Party, including the TMP, may file a request for
     administrative adjustment on its own behalf.

     3.6   Judicial Proceedings.  Any Party intending to file a petition under
     Code (S) 6226, 6228, or any other Code section with respect to any
     partnership item, or other tax matters involving the Partnership, shall
     notify the other Parties prior to such filing of the nature of the
     contemplated proceeding. In the case where the TMP is the Party intending
     to file such petition, such notice shall be given within a reasonable time
     to allow the other Parties to participate in the choice of the forum for
     such petition.  If the Parties do not agree on the appropriate forum, then
     the forum shall be chosen by majority vote. Each Party shall have a vote in
     accordance with its percentage interest in the Partnership for the year
     under audit.  If a majority cannot agree, the TMP shall choose the forum.  
     If a Party intends to seek review of any court decision rendered as a

                                       3
<PAGE>
 
     result of such proceeding, the Party shall notify the other Parties prior
     to seeking such review.

4.   TAX AND FMV CAPITAL ACCOUNT ELECTIONS

     4.1.  General Elections. For both income tax return and capital account
     purposes, the Partnership shall elect:

          (a)  to deduct currently intangible drilling and development costs
               ("ID");

          (b)  to use the maximum allowable accelerated tax method and the
               shortest permissible tax life for depreciation;
 
          (c)  to use the accrual method of accounting;
 
          (d)  to report income on a calendar year basis;

               of property and in Code (S) 743 for a transfer of a partnership
               interest. In the case of a distribution of property the TMP shall
               adjust all tax basis capital accounts. In the case of a transfer
               of a partnership interest the acquiring party(ies) shall
               establish and maintain its (their) tax basis capital account(s).

     4.2  Depletion.  Solely for FMV capital account purposes, depletion shall
     be calculated by using simulated percentage depletion within the meaning of
     Treas. Reg. (S) 1.704-1 (b)(2)(iv)(k)(2).  For purposes of a simulated
     percentage depletion calculation the depletion rate shall be the rate
     specified in Code (S) 613A(c)(1).

     4.3  Election Out Under Code (S) 761(a).  The TMP shall notify all Parties
     of an intended election to be excluded from the application of Subchapter K
     of Chapter 1 of the Code not later than sixty (60) days prior to the
     filing date or the due date (including extensions) for the Federal
     partnership income tax return, whichever comes earlier. Any Party that does
     not consent must provide the TMP with written objection within thirty (30)
     days of such notice.

     4.4  Other Tax or FMV Capital Account Elections or Consents.  Any election
     other than those referenced above must be approved by the affirmative vote
     of two (2) or more Parties owning a Majority Working Interest based upon
     post-Payout ownership.

5.   CAPITAL CONTRIBUTIONS AND FMV CAPITAL ACCOUNTS

     Party to the Partnership shall be (a) each Party's interest in the oil and

     connection with the acquisition, exploration, development, and operation of
     the lease(s), and all other costs characterized as contributions or
     expenses borne by such Party under the Agreement. The contribution of the
     leases and any other properties committed to the Partnership shall be made

     leases or other property as nominee of the Partnership.

     decreased as follows:

          5.2.1  The FMV capital accounts shall be increased by:  (i) the amount
                                                   ---------                    
          of money and the fair market value of any property contributed by each
          Party to the Partnership (net of liabilities assumed by the
          Partnership or to which the contributed property is subject); (ii) a
          Party's (S) 6.1 allocated share of Partnership income and gain, or
          items thereof; and (iii) that Party's share of Code (S) 705(a)(1)(B)
          items.

          5.2.2  The FMV capital accounts shall be decreased by:  (i) the amount
                                                   ---------

     if checked below:

     5.3  FMV Capital Account Revaluation. The FMV capital accounts will be
     revalued to reflect revaluation of partnership property according to Treas.
     Reg. (S) 1.704-1(b)(2)(iv)(9) if the Parties agree pursuant to (S) 4.4.

6.   PARTNERSHIP ALLOCATIONS

     6.1  FMV Capital Account Allocations. Each item of income, gain, loss, or
     deduction shall be allocated to each party as follows:

          6.1.1  Actual or deemed income from the sale, exchange, distribution
          or other disposition of production shall be allocated to the Party
          entitled to such production or the proceeds from the sale of such
          production. The amounts received from the sale of production and of
          the fair market value of production taken in kind by the Parties are
          deemed to be identical; accordingly, such items may be omitted from
          the adjustments made to the Parties' FMV capital accounts.

          6.1.2  Exploration cost, ID, and operating and maintenance cost shall
          be allocated to each Party in accordance with its respective
          contribution, or obligation to contribute, to such cost.

          6.1.3  Depreciation shall be allocated to each Party in accordance
          with its contribution, or obligation to contribute, to the cost of the
          underlying asset.

          6.1.4  Simulated depletion shall be allocated to each Party in
          accordance with its FMV capital account adjusted basis in each oil and
          gas property of the Partnership.

          6.1.5  Loss (or simulated loss) upon the sale, exchange, distribution,
          abandonment or other disposition of depreciable or depletable property
          shall be allocated to the Parties in the ratio of their respective FMV
          capital account adjusted basis in the depreciable or depletable
          property.

          6.1.6  Gain (or simulated gain) upon the sale, exchange, distribution,
          abandonment or other disposition of depreciable or depletable property
          shall be allocated to the Parties so that the FMV capital account
          balances of the Parties will most closely reflect their respective
          percentage or fractional interests under the Agreement. However, as
          provided in Treas. Reg. (S) 1.704-1(b)(4)(v) for oil and gas
          properties, the amount realized is allocated as follows: (i) first, an
          amount that represents recovery of adjusted simulated depletion basis
          is allocated (without being credited to the capital accounts) to the
          Parties in the same proportion as the aggregate simulated depletion
          basis was allocated to such Parties under this section; (ii) next,
          from the remainder of the amount realized, if any,

                                       6
<PAGE>
 
          an amount up to any remaining pre-contribution gain under Code 
          (S) 704(c), but only to the extent not included in the allocation
          under the first allocation step, is allocated to the Parties having
          contributed the respective property; and (iii) finally, any amount of
          realization remaining after the allocations under (i) and (ii) is
          allocated in accordance with the first sentence of this (S) 6.1.6.

          6.1.7  Costs or expenses of any other kind shall be allocated to each
          Party in accordance with its respective contribution, or obligation to
          contribute, to such costs or expenses.

          6.1.8  Any other income item shall be allocated to the Parties in
          accordance with the manner in which such income is realized by each
          Party.

     6.2  Tax Return and Tax Basis Capital Account Allocations

          6.2.1  Unless otherwise expressly provided in this (S) 6.2, the
          allocations of partnership items of income, gain, loss, or deduction
          for tax return and tax basis capital account purposes shall follow the
          principles of the allocations under (S) 6.1. However, the
          partnership's gain or loss on the taxable disposition of a partnership
          property in excess of the gain or loss under (S) 6.1, if any, is
          allocated to the contributing Party to the extent of such Party's pre-
          contribution gain or loss.

          6.2.2  The Parties recognize that under Code (S) 613A(c)(7)(D) the
          depletion allowance is to be computed separately by each Party. For
          this purpose, each Party's share of the adjusted tax basis in each oil
          and gas property shall be equal to its contribution to the adjusted
          tax basis of such property.

          6.2.3  The Parties recognize that under Code (S) 613A(c)(7)(D) the
          computation of gain or loss on the disposition of an oil and gas
          property is to be computed separately by each Party.

          6.2.4  Depreciation shall be allocated to each Party in accordance
          with its contribution to the adjusted tax basis of the depreciable
          asset.

          6.2.5  Any recapture of depreciation, ID, and any other item of
          deduction or credit shall, to the extent possible, be allocated among
          the Parties in accordance with their sharing of the depreciation, ID,
          or other item of deduction or credit which is recaptured.

          6.2.6  Any recapture of depletion shall be computed separately by each
          Party, in accordance with its depletion allowance computed pursuant to
          (S) 6.2.2.

                                       7
<PAGE>
 
          6.2.7  For partnership properties with FMV capital account values
          different from their adjusted tax bases the Parties intend that the
          allocations described in this (S) 6.2 constitute a "reasonable method"
          of allocating gain or loss under Treas. Reg. (S) 1.704-3(a)(1).

          6.2.8  Take-in-kind:

               6.2.8.1  Unless checked below, the income attributable to take-
               in-kind production will not be reflected on the tax return.

               6.2.8.2  The provision for taking production in-kind, as provided
               in the Agreement, is recognized as each Party's right to
               determine the market for its proportionate share of production.
               All items of income, deductions, and credits arising from such
               marketing of production shall be recognized by the Partnership
               and shall be allocated to each Party who designated such a
               market.

7.   TERMINATION AND LIQUIDATING DISTRIBUTION

     7.1  Termination of the Partnership. Termination shall occur on the earlier
     of the events described in Code (S) 708(b)(1)(A) or (B).

          7.1.1  Upon termination under Code (S) 708(b)(1)(B), each Party's FMV
          capital account shall be adjusted as provided in Treas. Reg. (S)1.704-
          1(b)(2)(iv)(l) and (S) 7.3. The distributions provided in (S)(S) 7.2
          through 7.4 shall be deemed to have occurred with the Partnership cash
          and properties deemed contributed to a new Partnership to which this
          Exhibit also applies.

          7.1.2 Upon termination under Code (S) 708(b)(1)(A), the business shall
          be wound-up and concluded, and the assets shall be distributed to the
          Parties as described below by the end of such calendar year (or, if
          later, within ninety (90) days after the date of such termination).
          The assets shall be valued and distributed to the parties in the order
          provided in  (S)(S) 7.2 through 7.4.

     7.2  Reversion. First, all cash representing unexpended contributions by
     any Party and any property in which no interest has been earned by any
     other Party under the Agreement shall be returned to the contributor.

     7.3  Balancing. Second, the FMV capital accounts of the Parties shall be
     determined as described hereafter. The TMP shall take the actions specified
     under this (S)7.3 in order to cause the ratios of the Parties' FMV capital
     accounts to reflect as closely as possible their interests under the
     Agreement. The ratio of a Party's FMV capital account is represented by a
     fraction, the numerator of which is the Party's FMV capital account balance
     and the denominator of which is the sum of all Parties' FMV capital account

                                       8
<PAGE>
 
     balances. This is hereafter referred to as the "balancing of the FMV
     capital accounts" and, when completed, the FMV capital accounts of the
     Parties shall be referred to as "balanced."

          7.3.1  The fair market value of ail Partnership properties shall be
          determined and the gain or loss for each property, which would have
          resulted if sold at such fair market value, shall be allocated in
          accordance with (S)(S)6.1.5 and 6.1.6. If hereafter any Party has a
          negative FMV capital account balance, that is a balance of less than
          zero, in accordance with Treas. Reg. (S)1.704-1(b)(2)(ii)(b)(3) such
          Party is obligated to contribute an amount of money to the Partnership
          sufficient to achieve a zero balance FMV capital account (the "Deficit
          Make-Up Obligation"). Moreover, any Party may contribute an amount of
          cash to the Partnership to facilitate the balancing of the FMV capital
          accounts. If after these adjustments the FMV capital accounts are not
          balanced,  (S)(S) 7.3.2 and 7.3.3 shall apply.

          7.3.2  If all Parties agree, any cash or an undivided interest in
          certain selected properties shall be distributed to one or more
          Parties as necessary for the purpose of balancing the FMV capital
          accounts.

          7.3.3  Unless (S) 7.3.2 applies, an undivided interest in each and
          every property shall be distributed to one or more Parties in
          accordance with the ratios of their FMV capital accounts.

          7.3.4  If a property is to be valued under (S) 7.3.1 or distributed
          pursuant to  (S)(S) 7.3.2 or 7.3.3 the Parties must first attempt to
          agree on the FMV of the property; failing such an agreement, the TMP
          shall cause a nationally recognized independent engineering firm to
          prepare an appraisal of the FMV of such property.

     7.4   Final Distribution. After the FMV capital accounts of the Parties
     have been adjusted pursuant to (S) 7.3, all remaining property and
     interests then held by the Partnership shall be distributed to the Parties
     in accordance with their positive FMV capital account balances.

8.   TRANSFERS, INDEMNIFICATION, AND CORRESPONDENCE

     8. 1   Transfer of Partnership Interests. Transfers of Partnership
     interests shall be governed by the Agreement. A Party transferring its
     interest, or any part thereof, shall notify the TMP in writing within two
     weeks after such transfer.

          8.2  Indemnification. This agreement does not provide for any
          indemnification to protect Parties against any tax cost from a Code
          (S)708(b)(1)(B) termination. If the Parties desire such
          indemnification, it must be expressly stipulated as a variation from
          this Exhibit.
