ITEM 1. BUSINESS
 
GENERAL
 
  Enserch Exploration, Inc. ("EEX" or the "Company"), an 83.3% owned
subsidiary of ENSERCH Corporation ("ENSERCH"), has been engaged in the
exploration for and the development, production and sale of natural gas and
crude oil since 1918. From 1985 through December 30, 1994, this business was
conducted primarily through Enserch Exploration Partners, Ltd. ("EP"), a
limited partnership in which a minority interest (less than 1% since 1989) was
held by the public. At year-end 1994, pursuant to a plan for the
reorganization of EP ("Reorganization"), EEX acquired, through a series of
transactions, all of the operating properties of EP Operating Limited
Partnership ("EPO"), EP's 99%-owned operating partnership, in exchange for
shares of EEX common stock. On December 30, 1994, the Reorganization was
consummated, EPO was merged into EEX, EP was liquidated and the EEX common
stock held by EP was distributed to EP's limited and general partners in
accordance with their partnership interests.
 
  EEX is one of the largest independent exploration and production companies
in the United States, with a reserve base of 1,572 billion cubic feet of
natural gas equivalent ("Bcfe") at January 1, 1997, as estimated by DeGolyer
and MacNaughton ("D&M"), independent petroleum consultants. Approximately 77%
of these reserves consist of natural gas.
 
RECENT DEVELOPMENTS
 
  ENSERCH/Texas Utilities Company Merger. In April 1996, ENSERCH announced
that it had entered into a merger agreement with Dallas-based Texas Utilities
Company ("ENSERCH/TUC Merger"). Under the terms of the agreement, a new
holding company will acquire the businesses of ENSERCH, excluding the
businesses of EEX and Lone Star Energy Plant Operations, Inc. ("LSEPO").
 
  Immediately prior to the consummation of the ENSERCH/TUC Merger, and as a
condition thereof, EEX will be merged into LSEPO ("EEX/LSEPO Merger"), LSEPO
will change its name to "Enserch Exploration, Inc." ("New EEX"), shares of EEX
will automatically be converted into shares of New EEX on a one-for-one basis
in a tax-free transaction, and ENSERCH will distribute to its shareholders, on
a pro rata basis, all of the shares of New EEX common stock it owns
("Distribution"). LSEPO, a wholly owned subsidiary of ENSERCH, operates and
maintains, under long-term contracts, a 255-megawatt ("MW") cogeneration
facility located in Sweetwater, Texas, a 62-MW cogeneration facility located
in Buffalo, New York, and a 160-MW cogeneration facility located in
Bellingham, Washington. In the EEX/LSEPO Merger, ENSERCH will receive
approximately 778,000 shares of New EEX for the value of LSEPO.
 
  The mergers, including the transactions contemplated by the mergers, were
approved by the shareholders of EEX, ENSERCH and TUC, in separate meetings, on
November 15, 1996. All regulatory approvals have been received except for
approval by the Securities and Exchange Commission ("SEC") under the Public
Utility Holding Company Act of 1935 where the approval process is proceeding.
The Railroad Commission of Texas ("RRC") has indicated no objection to the
ENSERCH/TUC Merger, and the Antitrust Division of the U.S. Department of
Justice ("DOJ") has notified ENSERCH and TUC that its investigation of the
proposed merger has been closed without the DOJ taking any action or requiring
TUC or ENSERCH to take any action. ENSERCH has also announced receipt of a
favorable tax ruling from the Internal Revenue Service to the effect that
neither ENSERCH nor its shareholders will recognize taxable gain in the
Distribution.
 
  The merger and transactions related thereto are fully described in the
Company's Proxy Statement dated October 2, 1996, as filed with the SEC, which
is incorporated herein by reference.
 
  Management Changes. On January 13, 1997, EEX named Thomas M Hamilton
Chairman and President, Chief Executive Officer of the Company, David R.
Henderson as Executive Vice President, Worldwide
 
                                       1
<PAGE>
 
Exploration, and B. K. Irani as Executive Vice President, Production and
Engineering. Mr. Hamilton came to EEX from Pennzoil Company where he was
Executive Vice President and President of Pennzoil Exploration & Production
Company. He succeeded Frederick S. Addy, interim Chairman, President and Chief
Executive Officer, who continues to serve as a Director of the Company. Mr.
Henderson previously was Senior Vice President of worldwide exploration at
Pennzoil Exploration & Production Company. Mr. Irani has previously served as
Senior Vice President, Offshore and International of the Company.
 
  Core Areas. Mr. Hamilton has initiated a review of the Company's business
with a focus on enhancing performance from the Company's core areas of
activity and the development of plans for maximizing the value of non-core
assets through optimization of cash flow and the disposition of low-return,
high-cost properties. EEX operations will be focused on existing core areas of
East Texas, the Gulf of Mexico Continental Shelf and the deep water Gulf of
Mexico. EEX also intends to vigorously pursue international opportunities. The
existing core areas account for more than 75% of EEX's proved reserves and
approximately 50% of total production. More than 90% of the Company's total
probable reserves, as estimated by D&M, are in the existing core areas.
Operating costs for properties located in core areas are relatively lower than
the overall cost profile for the Company. Assets in non-core areas will be
traded or sold with proceeds reinvested into core areas or utilized to reduce
debt.
 
  Offshore Activities--The Cooper Project. Production began at the Cooper
Project in the Garden Banks area of the Gulf of Mexico in September 1995.
Considered a deep-water project by industry standards, the floating production
facility ("FPF") is moored in 2,200 feet of water on Block 388. A 24-slot
subsea template rests on the ocean floor directly under the FPF. The FPF is
capable of drilling and producing simultaneously and is designed to
accommodate up to 40 thousand barrels ("MBbls") of oil and 120 million cubic
feet ("MMcf") of gas per day. EEX is the operator and owns a 60% interest in
this project. An affiliate of Mobil Corporation has a 40% interest. At year-
end 1996, gross daily production at the project had reached approximately 10
MBbls of oil and condensate and 15 MMcf of natural gas per day. Additional
development and exploratory drilling of identified prospects is expected
during 1997 as a part of a long-term development plan for the Cooper Project.
 
  In late July 1996, it was announced that mechanical problems had prevented
completion of the A-1 development well at the Cooper Project. EEX and its
partner are evaluating alternate drilling strategies to develop the extensive
proven hydrocarbon column at this location.
 
  The A-2 development well reached total depth of 9,835 feet encountering
three pay zones in the 7,200-foot, 7,600-foot and 9,800-foot sands in January
1997. In March 1997, the well was initially completed in the 9,800-foot sand,
which has a total of 116 feet of oil pay.
 
  The SB-3 exploratory well on Garden Banks Block 387 was also completed in
March 1997. The well was drilled to a total depth of 19,000 feet and was
completed in a 50-foot sand interval at a depth of 18,170 feet. Based on
initial flow rates, the well is expected to initially produce at rates in the
range of 20 to 25 MMcf of gas per day with associated condensate.
 
  Offshore Activities--The Allegheny Project. This project comprises a four-
block unit in the Green Canyon area of the Gulf of Mexico and is located
approximately 150 miles south of New Orleans, Louisiana, in 2,200 to 3,400
feet of water. The Allegheny Project is located in an area of the Gulf where
there is a great deal of exploration and development activity. EEX is the
operator and has a 40% interest in this project, an affiliate of Mobil
Corporation has 40% and an affiliate of Reading & Bates Corporation has 20%.
 
  Prior to 1996, three wells and one sidetrack had been drilled on Green
Canyon Block 254 with gross proved reserves equivalent to approximately 72
million barrels ("MMBbls") of oil attributed by D&M. During 1996, a well was
drilled on Block 298, bottoming on Block 297, reaching a total depth of 16,500
feet (measured depth), encountering 350 gross feet of pay (measured depth).
Although the well extended the field 3,000 feet to the south, subsequent
interpretation of the data revealed thinning of some previously mapped
reservoirs which, coupled with the newly discovered sands, resulted in a 20
MMBbl downward revision of reserves to 52 MMBbl gross proved reserves.
 
 
                                       2
<PAGE>
 
  In 1996, EEX and its partners began to identify alternative development
scenarios for the Allegheny Project. A joint project team was formed to
evaluate alternatives that are currently available for the design and
construction of production facilities. The project team will also design and
implement a development plan to optimize production from this project. The
additional engineering study and design will delay the project from its
previously planned early 1999 start-up. However, the design changes should
favorably impact the project's economics.
 
  Rocky Mountain Properties. During 1996, EEX sold substantially all of its
Rocky Mountain area properties, which were in six states, aggregated over
250,000 net acres and had proved reserves of 148 Bcfe at January 1, 1996.
These properties were mostly acquired as part of the acquisition of DALEN
Corporation ("DALEN") in 1995 and were not considered a core area for EEX.
 
  International Operations. In the Mudi field on the island of Java in
Indonesia, where EEX owns a 25% working interest, a development plan was
approved in 1996. Five wells have been drilled and are expected to be
completed in this field, and a stepout delineation well is being drilled.
Production is expected to commence in late 1997 or early 1998 initially at an
estimated 20 MBbls of oil per day. Gross reserves are estimated to be40 MMBbls
of oil and condensate.
 
SALES INFORMATION
 
  Sales data are set forth under "Operating Data" included in Appendix A to
this report.
 
MAJOR CUSTOMERS
 
  EEX sells its gas under both long- and short-term contracts. EEX markets
most of its gas through third-party gas marketing organizations while
maintaining a core staff to ensure market prices are received. In 1996,
Enserch Energy Services, Inc. ("EES"), the ENSERCH natural-gas marketing
subsidiary, was EEX's largest gas customer, purchasing gas under two long-term
variable-price contracts which terminated December 31, 1996. A division of
ENSERCH, Lone Star Gas Company ("LSG"), purchases gas under a long-term fixed-
price service contract which ends in March 1997. In 1996, approximately 34%
and 6% of EEX's natural gas volumes were sold to EES and LSG, respectively.
The termination of these contracts will not have a material adverse effect on
EEX's results of operations.
 
  EEX sells its oil under contracts that are for one year or less. Prices
generally are based upon field posted prices plus negotiated bonuses.
 
  EEX utilizes futures contracts, commodity price swaps and other financial
instruments to reduce exposure of its gas and oil production to price
volatility. See "Financial Review--Gas and Oil Market Volatility" and Note 10
of the Notes to Consolidated Financial Statements included in Appendix A for
additional information on hedging activities.
 
COMPETITION
 
  All phases of the gas and oil industry are highly competitive. EEX competes
in the acquisition of properties, the search for and development of reserves,
the production and sale of gas and oil and the securing of the labor and
equipment required to conduct operations. EEX's competitors include major gas
and oil companies, other independent gas and oil concerns and individual
producers and operators. Many of these competitors have financial and other
resources that substantially exceed those available to EEX. Gas and oil
producers also compete with other industries that supply energy and fuel.
 
GOVERNMENT REGULATION
 
  The gas and oil industry is extensively regulated by federal, state and
local authorities. Legislation affecting the gas and oil industry is under
constant review for amendment or expansion. Numerous departments and
 
                                       3
<PAGE>
 
agencies, both federal and state, have issued rules and regulations binding on
the gas and oil industry and its individual members, some of which carry
substantial penalties for the failure to comply. Inasmuch as such laws and
regulations are frequently amended, reinterpreted or expanded, EEX is unable
to predict the future cost or impact of complying with such laws and
regulations.
 
  The RRC regulates the production of natural gas and oil by EEX in Texas.
Similar regulations are in effect in all states in which EEX 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.
 
  Environmental Matters. Gas and oil operations are subject to extensive
federal, state and local laws and regulations, including the Comprehensive
Environmental Response, Compensation and Liability Act ("CERCLA"), also known
as the "Superfund Law," and similar state statutes and, with respect to
federal leases, to interruption or termination by governmental authorities on
account of environmental and other considerations. Regulations of the
Department of the Interior currently impose absolute liability upon the lessee
under a federal lease for the costs to clean-up pollution resulting from a
lessee's operations, and such lessee may also be subject to possible legal
liability for pollution damages. EEX maintains insurance against costs of
clean-up operations, but is not fully insured against all such risks. A
serious incident of pollution may result in the Department of the Interior
requiring lessees under federal leases to suspend or cease operation in the
affected area. With respect to any EEX operations conducted on offshore
federal leases, liability may generally be imposed under the Outer Continental
Shelf Lands Act for costs of clean-up and damages caused by pollution
resulting from such operations, other than damages caused by acts of war or
the negligence of third parties.
 
  The Oil Pollution Act of 1990 and regulations thereunder impose a variety of
regulations on "responsible parties" (which includes owners and operators of
offshore facilities) related to the prevention of oil spills and liability for
damages resulting from such spills in the United States waters. In addition,
it imposes ongoing requirements on responsible parties, including proof of
financial responsibility to cover at least some costs in a potential spill.
 
  The operations of EEX are also subject to the Clean Water Act and the Clean
Air Act, as amended, and comparable state statutes. The EPA is currently
implementing regulations pursuant to the Clean Air Act, and the states are
also implementing programs. EEX may be required to incur certain capital
expenditures over the next five to ten years for air-pollution control
equipment.
 
  EEX's onshore operations are subject to numerous United States federal,
state and local laws and regulations controlling the discharge of materials
into the environment or otherwise relating to the protection of the
environment, including CERCLA. These regulations, among other things, impose
absolute liability on the lessee under a lease for the cost of clean-up of
pollution resulting from a lessee's operations, subject the lessee to
liability for pollution damages, may require suspension or cessation of
operations in affected areas and impose restrictions on the injection of
liquids into subsurface aquifers that may contaminate groundwater. Persons who
are or were responsible for releases of hazardous substances under CERCLA may
be subject to joint and several liability for the remediation and clean-up
costs and for damages to natural resources. EEX has been named as a
potentially responsible party at a Texas State Superfund site. However, EEX
does not believe that any liabilities in connection with such matters will
have a material adverse effect on its business or results of operations.
 
  For offshore operations, lessees must obtain the approval of the Mineral
Management Service ("MMS"), a federal agency, and various other federal and
state agencies' approval for exploration, development and production plans
prior to the commencement of such operations. Similarly, the MMS has
promulgated other regulations governing the plugging and abandoning of wells
located offshore and the removal of all production facilities. Under certain
circumstances, including but not limited to, conditions deemed to be a threat
or harm to the environment, the MMS may also require any EEX operation on
federal leases to be suspended or terminated in the affected area.
 
                                       4
<PAGE>
 
  Other Laws and Regulations. Various laws and regulations require permits for
drilling wells and the maintenance of bonding requirements in order to drill
or operate wells and also regulate the spacing and location of wells, the
method of drilling and casing wells, the surface use and restoration of
properties upon which wells are drilled, the plugging and abandoning of wells,
the prevention of waste of gas and oil, the prevention and cleanup of
pollutants, the maintenance of certain gas/oil ratios and other matters.
 
  EEX's operations are also subject to various conservation requirements.
These include the regulation of the size and shape of drilling and spacing
units or proration units, the density of wells which may be drilled, maximum
rates of production and unitization or pooling of oil and gas properties.
 
  In the aggregate, compliance with federal and state rules and regulations is
not expected to have a material adverse effect on EEX's operations.

FORWARD LOOKING STATEMENTS--UNCERTAINTIES AND RISKS
 
  Written statements throughout this report on Form 10-K relating to EEX
management's intentions, hopes, beliefs, expectations or predictions of the
future are forward-looking statements. It is important to note that EEX's
actual results could differ materially from those projected in such forward-
looking statements. Information concerning some of the factors that could
cause actual results to differ materially from those in the forward-looking
statements are described below.
 
  Estimating Reserves and Future Net Cash Flows. Uncertainties are inherent in
estimating quantities and values of reserves and in projecting rates of
production, net revenues and the timing of development expenditures. The
reserve data represent estimates only of the recovery of hydrocarbons from
underground accumulations and are often different from the quantities
ultimately recovered. Any downward adjustment in reserve estimates could
adversely affect EEX.
 
  Operational Risks and Hazards. EEX's operations are subject to the risks and
uncertainties associated with finding, acquiring and developing gas and oil
properties, and producing, transporting and selling gas and oil. Operations
may be materially curtailed, delayed or canceled as a result of numerous
factors, such as accidents, weather conditions, compliance with governmental
requirements and shortages or delays in the delivery of equipment. Drilling
may involve unprofitable efforts, not only with respect to dry wells, but also
with respect to wells that are productive but do not produce sufficient net
revenues to return a profit after drilling, operating and other costs. Various
field operating hazards such as fires, explosions, blow-outs, equipment
failures, abnormally pressured formations and environmental accidents may
adversely affect production from successful wells. EEX's ability to sell its
gas and oil production is dependent on the availability and capacity of
gathering systems, pipelines and other forms of transportation.
 
  Offshore Risks. EEX's offshore Gulf of Mexico gas and oil reserves include
properties located in water depths of 20 to 3,400 feet where operations are by
their nature more difficult than drilling operations conducted on land. Deep
water drilling and operations require the application of more advanced
technologies, involving a higher risk of mechanical failure and inevitably
resulting in significantly higher drilling and operating costs. Furthermore,
offshore operations require a significant amount of time between the time of
discovery and the time the gas or oil is actually marketed, increasing the
market risk involved with such operations.
 
                                       5
<PAGE>
 
  Volatility of Gas and Oil Markets. EEX's operations are highly dependent
upon the prices of, and demand for, gas and oil. These prices have been, and
are likely to continue to be, volatile. Prices are subject to fluctuations in
response to a variety of factors that are beyond the control of EEX, such as
worldwide economic and political conditions as they affect actions of OPEC and
Middle East and other producing countries, and the price and availability of
alternative fuels, EEX's hedging activities with respect to some of its
projected gas and oil production, which are designed to protect against price
declines, may prevent EEX from realizing the benefits of price increases above
the levels of the hedges and protect it from incurring the detriments of price
decreases below the level of hedges. Because EEX's reserve base is
approximately 80% natural gas on an energy equivalent basis, it is more
sensitive to fluctuations in the price of natural gas. EEX follows the full
cost method of accounting for gas and oil properties. A decline in gas and oil
prices could cause a future write-down of capitalized costs and a non-cash
charge against income. See "Financial Review--Capitalized Costs."
 
  Government Regulation. EEX's business is subject to certain federal, state
and local laws and regulations relating to the drilling for the production of
gas and oil, as well as environmental and safety matters. See "Business --
Government Regulation."
 
ITEM 2. PROPERTIES
 
  EEX's domestic activities were focused in four regions in 1996: the Gulf of
Mexico; East Texas; Mid-Continent and other; and the Gulf Coast Region of
Texas, Louisiana, Mississippi and Alabama. The following table sets forth

  EEX purchased about 252,000 net acres of leasehold interests in 1996, 99,000
of which were in the Gulf of Mexico. EEX's Gulf of Mexico holdings totaled
some 487,000 net acres, with an average working interest of 43% in 234 blocks
and an overriding royalty interest in 9 blocks. EEX operates 148 offshore
blocks. EEX also canceled or allowed to expire two Gulf of Mexico leases
during 1996 following review of drilling activity on or near these areas and
after analysis of geophysical and geological findings.
 
  EEX 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 as follows:

Note:
   Productive wells are either producing wells or wells capable of
   commercial production, although currently shut-in. The term "gross"
   refers to the wells in which a working interest is owned, and the term
   "net" refers to gross wells multiplied by the percentage of EEX's working
   interest owned therein.
 
  At December 31, 1996, EEX was participating in 71 wells (34 net), which were
either being drilled or in some stage of completion.
 
  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
correspond to capital expenditures, since SEC 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 the timing of construction of platforms, pipelines and other necessary
facilities.

(1) Options are exercisable in stages of 25% on the first through the fourth
    anniversaries of the grant. Options become fully vested in the event of a
    change in control as defined in the plan.
(2) Fair market value on the date of grant.
(3) Represents the hypothetical present value of the option determined using
    Black-Scholes Option Valuation Method based upon the terms of the option
    grant and the Company's stock price as of the date of the grant. The
    actual value, if any, an executive may realize will depend on the excess
    of the stock price over the exercise price on the date the option is
    exercised and there is no assurance that the value ultimately realized
    will be at or near the value estimated by the Black-Scholes Option
    Valuation Method. The assumptions used to arrive at the values shown are
    as follows: Risk Free Interest Rate of 5.99% for February 16, 1996, awards
    and 7.09% for September 10, 1996, awards, based on the ten-year Treasury
    bond rate on the date of the grant, Stock Price Volatility of 37.0% based
    on the historical return volatility using weekly stock prices over the
    prior three years, no dividend yield.
(4) Reflects Phantom Stock Units granted under the Phantom Stock Plan for non-
    employee Directors. For a discussion of the Phantom Stock Plan, see
    "Compensation of Directors."
(5) The options granted in 1996 were relinquished at Mr. Junco's severance on
    October 30, 1996.

    prior to vesting at the same rate as paid to all shareholders. All
    restrictions are lifted in the event of a change in control and are
    subject to allocation in the event of retirement, disability or death
    during the performance period.
(2) All shares are earned if at the end of the performance term the Company's
    total shareholder return is at or above 110% of the weighted average of
    the peer group. For each percentage point that the Company's total
    shareholder return is below 110% of the weighted average of the peer group
    but above 100%, 2.5% of the shares will be forfeited and for each
    percentage point below 100%, 5% of the shares will be forfeited with no
    shares earned below 85%.

(3) Shares earned at the end of the three-year performance period will remain
    restricted, subject to continued employment for two additional years.
(4) Approval by the Company's Board of Directors of the EEX/LSEPO Merger
    constituted a change in control as defined in the 1996 Plan. As a result,
    the forfeiture provisions with respect to these shares lapsed upon such
    approval.
(5) This restricted stock award was relinquished at the time of Mr. Junco's
    severance of employment.

(1) Highest average covered compensation over any consecutive five-year
    period.
 
  Covered compensation under the Program includes base wages and annual-
performance based bonuses. The credited years of service under the Program, as
of February 28, 1997, for Messrs. Junco, Irani, Kincheloe, McCormick and
Williams are 19.7, 22.1, 38.1, 5.6 and 0.6 years, respectively, and the
highest average covered compensation during any consecutive five-year period
for each of them is $357,698, $201,096, $240,984, $214,838 and $620,000,
respectively. In 1996, the Company did not make any contribution or incur any
charge regarding the retirement of Mr. Biegler. Mr. Addy waived participation
in the retirement plan. The normal retirement benefit is in the form of a
benefit guaranteed for ten years and life thereafter and is not subject to any
deduction for Social Security or other offset amounts.
 
COMPENSATION OF DIRECTORS
 
  Directors are compensated by an annual retainer fee of $25,000 plus $1,250
for each board or committee meeting attended. In addition, a $2,500 per annum
fee is paid for services on a Board Committee, with an additional $1,000 per
annum paid to the Chairman of a Board Committee. Directors who are also
officers of the Company do not receive fees.
 
  In 1996, the Company adopted a Phantom Stock Plan ("Director Plan") for non-
employee directors. The purpose of the Director Plan is to align the economic
interests of the Company's directors with those of shareholders by linking
part of the compensation of directors to increases in the value of the Company
and to provide a financial incentive that will help attract and retain
directors of outstanding competence. Phantom stock units were awarded to each
non-employee director (which by the terms of the Plan also included Mr. Addy
during his service as Interim Chairman and President, Chief Executive Officer
of the Company) except
 
                                      15
<PAGE>
 
D. W. Biegler, who was serving at the time the Director Plan first became
effective. Awards are also made to non-employee directors at the time they are
first elected to the Board of Directors, and thereafter to each non-employee
director elected to the Board at the Company's annual meeting of shareholders.
Each award consists of phantom stock units ("Units"), the number of which is
determined by dividing $20,000 by the value of the Company's common stock on
the date of the grant. A Unit account, which is maintained for each director,
is adjusted to reflect changes in corporate capitalization, a stock split, a
transaction which may involve the merger, consolidation, separation, including
a spinoff, or other distribution of stock or property of the Company, a
corporate reorganization or any partial or complete liquidation of the
Company. Units are fully vested at the earlier of the director's retirement
from the board, his death or a change in control of the Company, as defined in
the Director Plan. The aggregate value payable on an account when it is closed
is determined by multiplying the value of one share of the Company's common
stock by the number of Units in the account. The sum paid out is payable in
cash or in the Company's common stock, at the director's election, and may be
deferred for up to ten years with interest to accrue on the account balance at
the prime rate as published in "The Wall Street Journal." In 1996, awards
valued at $20,000 each resulted in the credit of 2,092 Units to each of the
following non-employee directors: F. S. Addy, B. A. Bridgewater, Jr., M. P.
Mallardi and W. C. McCord.
 
EMPLOYMENT CONTRACTS, TERMINATION OF EMPLOYMENT AND CHANGE-IN-CONTROL
ARRANGEMENTS
 
  Mr. Addy executed a Restricted Stock Agreement with the Company in
connection with his service as interim Chairman and Chief Executive Officer.
The agreement provides that Mr. Addy receive 10,000 restricted shares upon
execution of the agreement plus 2,500 shares of restricted stock for each full
quarter of service, with the 2,500 share award for a full quarter to be
prorated for services less than a full quarter. The restrictions may not be
removed until the first to occur of (a) September 10, 1999, (b) the date Mr.
Addy ceases to be a Director of the Company or (c) Mr. Addy's death. Mr. Addy
waived all employee benefits.
 
  Messrs. Junco, Kincheloe, Irani and McCormick have executed change-in-
control agreements with the Company that provide certain benefits in the event
their employment is terminated in connection with a change in control of the
Company (as defined in the agreements). The agreements are for continuous
three-year terms until terminated by the Company upon specified notice and
continue for three years following a change in control of the Company. The
agreements provide that if the officer is terminated or if the officer elects
to terminate employment under certain circumstances during the period of six
months preceding and within three years following a change in control of the
Company, the officer shall be entitled to a lump-sum severance payment of
three times the sum of the officer's base salary and target bonus (but not in
excess of the aggregate base salary that could be earned up to the officer's
normal retirement date), a prorated bonus in the year of termination, the
value over exercise price of certain unexercised stock options, a three-year
continuation of employee benefits, the equivalent of two years of service
credit under the retirement program, and reimbursement of certain legal fees,
expenses, and any excise taxes. Under the terms of such agreement, the vote of
the shareholders to approve the EEX/LSEPO Merger caused a change in control to
occur.
 
  Mr. Irani has entered into a retention bonus arrangement under which the
Company would pay a cash bonus of $210,000 upon the attainment of eighteen
months of continuous employment following the EEX/LSEPO Merger. The bonus
payment is payable on a prorated basis in the event that, on or prior to the
bonus payment date, the employee dies or becomes disabled, unless during such
period he is terminated for cause.
 
  Mr. Junco and the Company entered into an agreement in connection with his
October 30, 1996, termination as an officer of the Company. Under the
agreement, Mr. Junco received payment as described in Note 10 to the Summary
Compensation Table which included settlement of a change-in-control agreement.
The Company also agreed to maintain Mr. Junco's life, health, accident and
disability insurance for one year and reimburse amounts required for excise
tax payments, if any. Mr. Junco also relinquished all rights to options and
shares of restricted stock of the Company and ENSERCH Corporation held by him.
 
  Mr. Kincheloe and the Company entered into an agreement in connection with
his August 31, 1996 retirement. Under the agreement, which included settlement
of his change-in-control agreement, Mr. Kincheloe
 
                                      16

received $66,000 at his retirement, monthly payments of $20,000 for the months
of September 1996 through April 1997, the continued right to receive the net
value of options for Company common stock and ENSERCH common stock, based on
their highest value within six months prior to his retirement date and the
amount required for excise tax payments, if any.
 
BOARD COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION
 
                         COMPENSATION COMMITTEE REPORT
 
  In determining executive compensation, the Committee is guided by three
primary objectives:
 
  . Offer incentive for business success by putting a significant portion of
    each executive's total pay at risk, based on company performance
    observing, in the short term, desirable operating results and, in the
    long term, total shareholder return.
 
  . Attract and keep outstanding executives by providing compensation
    opportunities consistent with those in the Company's industry for similar
    positions.
 
  . Encourage career service by providing retirement income consistent with
    industry practice.
 
  The Committee's action regarding compensation of executives in the first
quarter of the year was consistent with past practices and the above stated
objectives. However, compensation matters were impacted by the announcement by
ENSERCH Corporation in April of 1996 of its intention to distribute to its
shareholders its 83.4% of the Company's shares, the issues that developed
while posturing the Company for the transition to a fully independent Company
and terminations that occurred during the year.
 
  Chief Executive Officer--Cash Compensation. Mr. J. T. Williams served as
Chief Executive Officer for the first month of 1996, having served in that
position since mid-1995 in association with the Company's acquisition of DALEN
Corporation for which he served as Chief Executive Officer, and his
compensation was negotiated as part of an employment contract concluded at the
time of purchase. Mr. Williams resigned from the Company on February 1, 1996,
and was paid severance in accordance with his employment contract and an
applicable severance plan continuing from DALEN. Mr. Biegler began serving as
Chairman and Chief Executive Officer on February 1, 1996, and served in that
capacity until September 10, 1996, when it was determined by the Board, with
Mr. Biegler's concurrence, that it would better facilitate the transition to
an independent company for the Board to select an interim Chairman and Chief
Executive Officer to serve until a permanent chief executive officer could be
found. Mr. F. S. Addy, one of the Company's outside directors, was selected to
serve as interim Chairman and Chief Executive Officer on September 10, 1996.
Other than the award of stock options and performance-based restricted stock
as described in the tables, Mr. Biegler was not compensated by the Company in
1996. However, as described in the table, a portion of Mr. Biegler's cash
compensation from ENSERCH Corporation was allocated to the Company in 1996 for
his services made to the Company. Mr. Addy received no cash compensation
during his service with the Company but was paid in Company restricted stock
at the rate of 2,500 shares for each quarter of service with proportionate
shares for partial quarters and with an initial award of 10,000 shares.
 
  Other Named Executive Officers--Cash Compensation. Salary levels for the
other named executive officers are based upon assessment of each individual's
performance, experience and value in attaining corporate financial and
strategic objectives and are set within salary ranges based on surveys of
prevailing practice with the mid-point targeted for the expected level of
performance, experience and value. The Committee compares the Company's annual
cash payments (both salary and annual incentive) for named executive officers
to recognized annual surveys of practice in its industry. Industry practice is
observed from surveys conducted by Organization Resources Counselors for the
"Energy 27" Comparator Group and William M. Mercer, Incorporated. Together
they constitute a statistically valid database for this purpose and the
Committee is guided by it. The industry specific surveys used include all but
one of those companies found in the performance graph's Dow Jones Oil-
Secondary Index. The sole use of the smaller number of companies in that peer
group produces
 
                                      17
<PAGE>
 
pay data comparisons that are not considered as statistically meaningful or
useful for the purpose of salary comparisons, and the group of companies in
that peer group does not include all of the companies that are the Company's
most direct competitors for executive talent.
 
  During 1996, the aggregate salaries of the named executive officers who were
still employed by the Company at year end, not including Mr. Addy, summed to
an amount equal to 14% above the sum of the size-adjusted median survey
salaries for their positions. One of the named executive officers received a
salary increase during 1996 which, on an annualized basis, amounted to 4.7% of
the named executive officer's salary.
 
  Incentive Plan Compensation. It is the practice of the Company, which is
endorsed and effected by the Committee, to encourage both desirable annual
operating results and long-term total shareholder return by annual incentive
opportunities that put an important portion of total pay at risk subject to
the achievement of financial and operating goals. The portion of compensation
at risk is intentionally higher at higher executive levels in the Company.
Consequently much of a named executive officer's compensation is at risk, with
potential annual and long-term incentives, at target levels, placing up to 50%
of total compensation opportunity at risk. The Committee also considers
comparative data when determining the potential size of both annual and long-
term incentive awards.
 
  By year end Messrs. Irani and McCormick were the only named executive
officers participating in the Company's Performance Incentive Plan. The level
of this opportunity is designed to be consistent with industry practice. Their
target awards in 1996 ranged from 35% to 40% of salary. In 1996, Plan awards
required the achievement of goals set by the Committee at the beginning of the
year including operating income attainment and reserve finding-cost
effectiveness. Funding, based on results, could have ranged from zero to 150%
of the target awards. However, after a review of 1996 operating results, the
various performance targets and the circumstances relating to the upcoming
spin off, the Committee determined that it would be appropriate to waive
previously approved performance factors and authorized individual participant
reviews to determine the extent to which 1996 goal achievement would be
recognized for purposes of 1996 bonus payouts. This resulted in awards for
Messrs. Irani and McCormick of 136% and 71%, respectively, of target.
 
  Stock Incentive Plan. In February of 1996, the Company offered additional
incentive for stock price growth and total shareholder return through the
award of Performance-Based restricted stock under the Company's Stock
Incentive Plan, in which Messrs. Biegler and Junco participated, and stock
options under the Company's Stock Incentive Plan, in which Messrs. Biegler,
Junco, Irani and McCormick participated. In addition, after a decision by the
full Board regarding the need to retain and extend additional incentives to
key executives in the face of certain disruptions occurring as a result of the
upcoming spin off, in September the Company made additional awards of
Performance-Based restricted stock and stock options to Messrs. Junco, Irani
and McCormick. The awards of Performance-Based restricted stock are subject to
forfeiture in whole or in part unless specific goals which have been
determined by the Compensation Committee are achieved. The goals compare the
three year total shareholder return of the Company to the Dow Jones Oil-
Secondary Index used in the performance graph in the Company's 1996 Form 10-K.
After the three year goals are met, the restricted stock is subject to an
additional requirement of continued employment for two more years. Awards are
made to achieve the earlier stated objective of causing a significant portion
of each executive's total pay to be at risk and dependent on total shareholder
return primarily through stock price growth as well as the objective of
keeping outstanding executives by providing compensation opportunities similar
to those provided in the Company's industry. The Committee considered the
objective that the executive have an important incentive for stock price gain.
In determining the size of Performance-Based restricted stock and stock option
awards, the Committee used its discretion and was not bound by any pre-adopted
formulas. Performance-Based restricted stock and stock option awards in 1996
and options held at year end are described in the tables.
 
  Change-in-control provisions of the Company's Stock Incentive Plan operated
in 1996 to lift the restrictions on Performance-Based restrictive stock held
by Messrs. Biegler and Junco as described in the table. Mr. Junco resigned his
position on October 31, 1996, and was paid a settlement that included
surrender of his stock options, restricted stock, rights under his change-in-
control agreement and other amounts owing to him.
 
                                      18
<PAGE>
 
  Retirement Plan. The Company encourages career employment and it is endorsed
by the Committee. Its retirement benefits are an essential part of that
policy. They are described, for the named executive officers, in the Pension
Plan Table. The Committee periodically reviews executive retirement benefits
to ensure that they continue to meet the Company's needs and are consistent
with good corporate practice.
 
  Section 162(m). No formal policy has been adopted by the Company with
respect to qualifying compensation paid to its executive officers for
deductibility under Section 162(m) of the Internal Revenue Code. In the event
that any new compensation programs are proposed in the future, it is expected
that they will be structured with a view toward qualifying for deductibility
just as were the amendments to the 1994 Stock Incentive Plan as approved by
shareholders in 1996. The Committee does not anticipate that current
compensation levels will result in loss of any tax deductibility.

PERFORMANCE GRAPH
 
  Set forth below is a line graph comparing the percentage change in the
cumulative total shareholder return on the Company's Common Stock against the
cumulative total return of the S&P 500 Composite Stock Index and the Dow Jones
Oil-Secondary Index since the Company's stock first began trading. The graph
assumes that the value of the investment in the Company's Common Stock and
each index was $100 at January 3, 1995, the date the Company's stock first
began trading, and that all dividends are reinvested. The publicly traded
units of EP for the period prior to 1995 are not included in the performance
graph because such partnership interest was valued on a different basis from
the Common Stock currently traded and any comparisons would be inappropriate.

            SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE
 
  Section 16(a) of the Securities Exchange Act of 1934 requires the officers
and directors of the Company, and persons who own more than 10% of a
registered class of the equity securities of the Company, to file reports of
beneficial ownership and changes in beneficial ownership with the SEC and the
New York Stock Exchange. Based solely on its review of the copies of such
reports received by it, or written representations from certain reporting
persons that no Forms 5 were required for those persons, the Company believes
that during 1996, its officers, directors and greater than 10% shareholders
complied with all applicable filing requirements.

                               FINANCIAL REVIEW
 
1996 RESULTS OF OPERATIONS COMPARED WITH 1995
 
  Net income was $10.8 million ($.09 per share) for 1996, compared with a net
loss of $12.5 million ($.11 per share) for 1995. Results for 1996 were
adversely impacted by nonrecurring charges of $2.8 million after tax ($4.3
million pre-tax) related to the Company's pending separation from ENSERCH
Corporation (ENSERCH) and associated management changes. The year to year
improvement is primarily attributable to higher commodity prices in 1996 and a
full year's contribution to production volumes from properties acquired in
1995 and the Cooper Project. Operating income was $36.8 million in 1996,
compared with an operating loss of $6.2 million in 1995.
 
  Revenues for 1996 were $330 million, a $110 million (50%) increase from
1995, reflecting a $64 million (41%) increase in natural gas revenues, and a
$46 million (72%) improvement in oil and other revenues. The average natural
gas sales price per thousand cubic feet (Mcf) was $2.20 in 1996 compared with
$1.74 in 1995. Natural gas production increased to 101 billion cubic feet
(Bcf) in 1996, 11% higher than in 1995. The higher natural gas volumes
primarily resulted from 1996 operations containing a full year of production
from the properties acquired in the acquisition of DALEN Corporation in June
1995. Higher oil revenues in 1996 reflect a 15% improvement in the average
sales price and a 52% increase in sales volumes due primarily to the continued
development of the Cooper Project and the DALEN acquisition.
 
  Production and operating expenses for 1996 were $24 million (49%) higher
than in 1995, primarily due to a full year's activity from the Cooper Project
(up $15 million), and the properties acquired in the DALEN acquisition.
Exploration expenses were slightly higher in 1996, reflecting increased costs
from international exploration activity. General and administrative expenses
increased $5.1 million from 1995, reflecting a full year's impact of the DALEN
acquisition and $3.4 million for costs associated with the Company's pending
separation from ENSERCH and related management changes.
 
  The depreciation and amortization rate per thousand cubic feet of natural
gas equivalent (Mcfe) increased to $1.11 in 1996, from $1.03 in 1995,
principally due to the downward reserve revisions in two offshore deep water
projects.
 
  EEX sold substantially all of its Rocky Mountain area properties in 1996.
Sales proceeds of $116.5 million, less $5.5 million in closing costs and
income from the April 1, 1996 effective date to the closing dates, were
received and used to reduce bank borrowings. The properties sold contributed
$1.6 million to 1996 operating income, with total revenues of $22.2 million
and operating expenses of $20.6 million. Natural gas revenues were $15.2
million on sales of 10.8 Bcf, and oil and natural gas liquids revenues totaled
$7.0 million on sales of 504 thousand barrels (MBbls).
 
  Interest and other financing costs for 1996 were $23 million, compared with
$15 million in 1995. Interest in 1996 includes a full year's impact from the
debt incurred to finance the DALEN acquisition in June 1995 and the Cooper
Project capital lease, partially offset by the reduction in debt from proceeds
of property sales. Interest on the Cooper Project capital lease was deferred
through September 1995, the date of first production.
 
  The pro forma incremental impact on 1997's results of operations, compared
with 1996, of refinancing the Cooper Project equipment and facilities in
December 1996 and capitalization of the associated operating sublease will be
a reduction in production and operating expense of some $15 million, an
increase in the amortization rate of approximately $0.05 per Mcfe, and an
increase in interest costs of some $10 million.
 
  For the year ended December 31, 1996 the Cooper Project added $1.2 million
to operating income, but detracted $2.6 million from net income. Operating
results in 1996 were negatively impacted when the A-1 development well
encountered mechanical difficulties which prevented completion. Two additional
wells, the
 
                                      A-4
<PAGE>
 
SB-3 exploratory well on Garden Banks Block 387 and the A-2 development well
on Garden Banks Block 388 have been completed with first production expected
in the first quarter of 1997. See Item 1: Business, for additional
information.
 
1995 RESULTS OF OPERATIONS COMPARED WITH 1994
 
  EEX had a net loss of $12.5 million ($.11 per share) for 1995, compared with
pro forma net income of $7.5 million ($.07 per share) in 1994 after income
taxes on partnership operations. Results for 1994 benefitted from a $4.9
million after tax ($7.6 million pre-tax) gain from the sale of assets. There
was an operating loss of $6.2 million in 1995, compared with operating income
of $32 million in 1994.
 
  DALEN's operations are included since their acquisition on June 8, 1995 and
contributed 1995 operating income of $6.9 million, with revenues of $70.4
million and operating expenses of $63.5 million. Natural gas revenues were $49
million on sales of 31 Bcf at an average sales price of $1.60 per Mcf. Oil and
other revenues totaled $21 million; the average sales price for oil was $16.61
per barrel (Bbl), and oil sales volumes were 1.1 million barrels (MMBbls).
 
  The following comparisons of 1995 and 1994 operating results exclude the
impact of DALEN in 1995 and the previously noted unusual item in 1994. There
was an operating loss for 1995 of $13 million, compared with income of $24
million for 1994. Revenues for 1995 were $29 million (16%) lower than in 1994,
reflecting a $37 million (25%) decrease in natural gas revenues, but an $8
million (23%) improvement in oil and other revenues. The average natural gas
sales price per Mcf of $1.82 in 1995, excluding DALEN, declined 15% from the
1994 average of $2.15, causing a $23 million decline in revenues. Natural gas
sales volumes of 59 Bcf, excluding DALEN, were 12% less than in 1994, reducing
revenues by $14 million. The lower volumes primarily resulted from less
capital spending to replace gas production due to low gas prices and the
normal decline in production from several mature fields and the Mississippi
Canyon Block 441 in the Gulf of Mexico. Higher oil revenues reflect a 10%
improvement in the average sales price and a 12% increase in sales volumes
from the start-up of production from the Cooper Project in late September, and
increased production from exploration and development activities in Hardeman
and Shackelford counties in North Texas.
 
  Production and operating expenses for 1995, excluding DALEN, were $5.1
million (16%) higher than in 1994, primarily due to expenses of $4.4 million
for the Cooper Project and higher maintenance costs. The commencement of sales
from the Cooper Project in late September detracted from 1995 results,
producing an operating loss of $1.9 million, as fixed operating costs exceeded
revenues from the initial levels of production. Exploration expenses were $1.9
million higher than in the 1994 period due to increased international
exploration activity. General and administrative expenses increased $5.3
million from 1994, with 1995 expenses including a $1.8 million provision for
injuries and damages claims and a $1.0 million charge for severance costs
related to the DALEN acquisition, while 1994 expenses benefited from credits
of $2.0 million associated with litigation accruals.
 
  The total amortization rate per Mcfe was $1.03 in 1995, compared with $1.00
in 1994. The increase in 1995 over 1994 was primarily due to the conversion of
a part of the Cooper Project lease from an operating to a capital lease in
connection with the year end 1994 reorganization, partially offset by a
benefit resulting from reserve additions for the Allegheny Project and DALEN.
Excluding DALEN, a lower level of production caused depreciation and
amortization to be less in 1995 than in 1994.
 
  Interest and other financing costs for 1995 were $15 million, compared with
$21 million for 1994. The 1995 costs are primarily associated with the DALEN
acquisition. Interest for 1994 related to debt assumed by ENSERCH companies in
connection with the reorganization.
 
  The pro forma impact on 1994's net income as shown on EEX's Statements of
Consolidated Operations of the incorporation of EP and the assumption of debt
by ENSERCH companies, would be to decrease interest $20.9
 
                                      A-5
<PAGE>
 
million and increase income taxes a total of $11.6 million, $4.3 million on
partnership operations and $7.3 million on the interest reduction.
 
RESERVES
 
  EEX's natural gas reserves, as estimated by DeGolyer and MacNaughton,
independent petroleum consultants (D&M), at January 1, 1997 were 1.22 trillion
cubic feet (Tcf), compared with 1.36 Tcf the year earlier. Additions to and
purchases of natural gas reserves in 1996 replaced gas produced from retained
properties after adjusting for the sale of 124 Bcf of gas reserves. As a
result, natural gas reserves at year end 1996 for retained properties were
little changed from the year earlier. Oil and condensate reserves, including
natural gas liquids, were 59 MMBbls, down 8.6 MMBbls compared with the year
earlier level of 71 MMBbls after adjusting for the sale of 3.7 MMBbls,
additions at 102% of 1996 adjusted production and downward revisions of 8.2
MMBbls at the Company's deep water projects in the Gulf of Mexico. The
downward revisions resulted from the performance of two producing wells at the
Cooper Project and the thinning of some previously mapped reservoirs as a
result of additional drilling at the Allegheny Project.
 
GAS AND OIL MARKET VOLATILITY
 
  Results of operations are largely dependent upon the difference between the
prices received for gas and oil produced and the costs of finding and
producing such resources. On an energy equivalent basis, gas reserves at
January 1, 1997 constituted approximately 80% of total reserves, and gas
production accounted for approximately 77% of total production for 1996.
Accordingly, variations in gas prices have a more significant impact on
operations than variations in oil prices. Gas production as a percentage of
total production is expected to decrease as a result of the development of the
offshore Gulf of Mexico properties.
 
  A portion of the risk associated with fluctuations in the price of natural
gas and oil is managed through the use of hedging techniques such as gas and
oil swaps, collars and futures agreements. EEX fixed the price on 1996
production volumes of 43 Bcf of natural gas (43% of production) at an average
price of $2.11 per Mcf and 2.7 MMBbls of oil (52% of production) at an average
price of $19.58 per Bbl. In total, gas and oil price hedging activities
decreased 1996 revenues by $20.3 million and increased 1995 and 1994 revenues
by $.1 million and $4.3 million, respectively. At December 31, 1996, EEX had
outstanding swaps, collars and futures agreements that were entered into as
hedges extending through December 31, 1997 to exchange payments on 32 Bcf of
natural gas and 365 MBbls of oil. At December 31, 1996 there were $3.0 million
of net unrealized and unrecognized hedging gains based on the difference
between the strike price and the New York Mercantile Exchange futures price
for the applicable trading month. In addition, there were $5.1 million of
realized losses on hedging activities which were deferred and will be applied
as a reduction in revenues in January 1997, the month of physical sale of
production.
 
CAPITALIZED COSTS
 
  At January 1, 1997, estimated future net cash flows, before income taxes,
from EEX's owned proved oil and gas reserves, based on average December 1996
prices of $3.37 per Mcf of natural gas and $23.33 per barrel of oil were $3.9
billion. The net present value of such cash flows after income taxes and
discounted at 10%, was $1.7 billion, which is the basis for the SEC-prescribed
cost center ceiling for the full cost accounting method. The margin between
the cost center ceiling and the unamortized capitalized costs of U.S. oil and
gas properties was about $540 million at December 31, 1996.
 
  Product prices, production rates, levels of reserves and estimates of future
development costs all influence the calculation of the cost center ceiling,
making it difficult to project. Gas and oil prices are subject to seasonal and
other fluctuations and, from time to time, may vary significantly. Product
prices generally have the greatest impact on the cost center ceiling. At
December 31, 1996, a $0.10 per Mcf change in the price of natural gas has
about a $45 million impact on the cost center ceiling; a $1.00 per barrel
change in the oil price has about a $20 million impact.
 
                                      A-6
<PAGE>
 
  The SEC-prescribed full cost accounting rules require registrants to
calculate the cost center ceiling limitation at the end of each quarter using
current prices and costs. Prices for natural gas and oil have declined sharply
since the end of 1996. If there is not a substantial improvement in prices or
mitigating changes in the other factors involved in the calculation by the end
of the first quarter, the carrying value of EEX's oil and gas properties
almost certainly will be above the SEC-prescribed cost center ceiling. Such
conditions would necessitate a significant write-down of gas and oil
properties and a non-cash charge against earnings for the quarter. Based on
circumstances existing in March 1997 and without any pricing improvement or
mitigating changes, such a write-down could range from $225 to $250 million
after tax.
 
  Management believes the low prices required to be used in the calculation
are not representative of the prices EEX will receive for its production in
the future. A non-cash write-down of oil and gas properties will reduce future
depreciation and amortization expense but will not impact future cash flows.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  During 1996, EEX took certain actions to assure its liquidity and access to
financial resources to fund its investment and growth opportunities. EEX
renewed its $350 million revolving credit facility extending it to five years.
At December 31, 1996, $235 million was unused. EEX converted its Cooper
Project equipment leases, which had been with an ENSERCH affiliate, to fifteen
year leveraged leases with third party financial institutions for $229
million. EEX also arranged a $200 million, seven year operating lease
commitment from a group of banks to finance the construction of its share of
the Allegheny Project offshore equipment and facilities, of which $182 million
was unused at year end. EEX made minor changes in other facilities to ensure
continued availability of its financial resources to meet its planned
activities. See Note 7 of the Notes to Consolidated Financial Statements for
additional information.
 
CASH FLOWS
 
  EEX funded the 1996 business plan and reduced financings by $74 million,
primarily from operations and monetization of non-core assets. Net cash flows
from operating activities increased $51 million to $135 million, compared with
$84 million in 1995 and $62 million in 1994. Investing activities required net
cash flows of $63 million in 1996, compared with $388 million in 1995 and $109
million in 1994. The 1995 requirement included $333 million required for the
DALEN acquisition and $86 million provided by the collection of a note
receivable from an affiliated company. Proceeds from the disposition of
property, plant and equipment in 1996 include amounts received from the sale
of the Rocky Mountain area and other properties. In 1995, proceeds include
amounts received from the sale of interests in the Cooper and Allegheny
projects. Capital expenditures of $204 million in 1996 increased $15 million
from 1995, principally related to normal exploration and development
activities.
 
  EEX intends to utilize substantially all of its internally generated cash
flows for growth of the business and expects to have ample cash flow from
operations and the continuous monetization of non-core assets to fund its
business plans. Borrowings under EEX's credit facilities may be used to
supplement temporary cash flow needs. EEX does not anticipate paying cash
dividends in the foreseeable future.
 
CAPITAL STRUCTURE
 
  Debt and preferred securities of a subsidiary represented 35% of total
capitalization of $1.5 billion for December 31, 1996, compared to 30% of total
capitalization of $1.3 billion for December 31, 1995. This increase was due
primarily to the conversion of the operating sublease to a capital lease when
the Cooper Project leases were refinanced, offset by reduced bank borrowings
and improved shareholders' equity. See Note 7 of the Notes to Consolidated
Financial Statements for additional information.

CAPITAL BUDGET
 
  Planned 1997 capital expenditures will range from $175 million to $200
million, compared with actual expenditures of $204 million in 1996 and $189
million in 1995. Capital expenditure amounts exclude costs of offshore
equipment and facilities financed under operating lease arrangements of $25
million in 1996, $24 million in 1995, and are expected to be minimal in 1997.
 
FOURTH QUARTER RESULTS
 
  Fourth quarter 1996 net income was $3.3 million ($.03 per share), compared
with a net loss of $5.4 million ($.04 per share) for the 1995 fourth quarter.
Operating income for the 1996 fourth quarter was $7.8 million versus an
operating loss of $4.7 million for the same period of 1995. The increased
fourth quarter 1996 income reflects a 44% increase in the average sales prices
per Mcfe from 1995 to 1996, partially offset by costs related to the Company's
pending separation from ENSERCH and associated management changes, and
increased amortization expense as previously noted.

                         INDEPENDENT AUDITORS' REPORT
 
To the Shareholders and Board of Directors of Enserch Exploration, Inc.:
 
  We have audited the accompanying consolidated balance sheets of Enserch
Exploration, Inc. and subsidiaries (the "Company") as of December 31, 1996 and
1995, and the related statements of consolidated operations, cash flows and
owners' equity for each of the three years in the period ended December 31,
1996. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the 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 consolidated financial position of the Company at December 31,
1996 and 1995, and the results of their operations and their cash flows for
each of the three years in the period ended December 31, 1996, in conformity
with generally accepted accounting principles.

  Management has established and maintains internal accounting controls that
provide reasonable assurance as to the integrity and reliability of the

                           ENSERCH EXPLORATION, INC.
 
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
  Enserch Exploration, Inc. (EEX), a natural gas and oil exploration and
production company with activities focused in Texas and the Gulf of Mexico, is
83.3% owned by ENSERCH Corporation (ENSERCH) at year end 1996. All dollar
amounts, except per share amounts, in the notes to consolidated financial
statements are stated in thousands unless otherwise indicated.
 
1. ORGANIZATION AND BASIS OF PRESENTATION
 
  Prior to December 30, 1994, the operations of EEX, a corporation, were
conducted through Enserch Exploration Partners, Ltd. (EP), a partnership. EP
was a publicly traded entity with published financial statements. On December
30, 1994, through a series of transactions, EEX acquired all of the
partnership interests of EP Operating Limited Partnership (EPO), the 99% owned
operating partnership of EP, and EP received common stock of EEX. Certain
affiliates of ENSERCH other than EEX (collectively, the "ENSERCH Companies")
also received EP's interest in and assumed EP's obligations under certain
equipment lease arrangements (the equipment was simultaneously subleased to
EEX) and assumed approximately $395 million principal amount of EP's
indebtedness, plus accrued interest.
 
  In 1995, EEX acquired the international gas and oil and SACROC operations
from ENSERCH in exchange for cash and EEX Common Stock. ENSERCH's historical
carrying value of the assets acquired and liabilities assumed has been
recorded by EEX.
 
  The financial statements of EEX for periods prior to December 30, 1994
include the assets, liabilities, operations and cash flows of EP, restated to
include the international gas and oil operations and the SACROC operations in
a manner similar to a pooling-of-interests since the operations were under the
common control of ENSERCH prior to the establishment of EEX. No recognition
was given to income taxes in the financial statements of EP. EEX, as a
corporation, is a taxable entity. Pro forma information for the change in tax
status includes an adjustment for income taxes on the partnerships' operations
at the applicable statutory rate.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  The consolidated financial statements include the accounts of EEX and its
subsidiaries. The preparation of financial statements requires the use of
significant estimates and assumptions by management; actual results could
differ from those estimates.
 
  Earnings per share applicable to common stock are based on the weighted
average number of common shares outstanding during the period, including
common equivalent shares when dilutive.
 
  Gas and Oil Properties--The full cost accounting method as prescribed by the
Securities and Exchange Commission (SEC) is followed for gas and oil
properties. Under this method, all acquisition, exploration and development
costs incurred, including salaries, benefits and other internal costs directly
attributable to these activities, are capitalized. All costs associated with
production and general corporate activities are expensed in the period
incurred. Costs directly associated with the acquisition and evaluation of
unproved gas and oil 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. Amortization of evaluated gas and oil
properties, including assets acquired under capital leases, 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. At
December 31, 1996, estimates of future site restoration, dismantlement and
abandonment costs, as assessed on an overall cost center basis, were less than
estimates of future salvage values. Therefore, no accruals were required.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  Derivative Instruments--The Company frequently enters into swaps, futures,
options and other derivative contracts to hedge the impact of market
fluctuations in gas and oil prices on anticipated future gas and oil
production. The Company defers the impact of changes in the market value of
the contracts that serve as hedges until the related transaction is completed.
The Company also enters into interest rate swaps to manage risk associated
with interest rates and reduce the Company's exposure to interest rate
fluctuations. Interest rate swaps are valued on a periodic basis, with
resulting differences recognized as an adjustment to interest and other
financing costs over the term of the agreement.
 
  Stock Based Employee Compensation--Statement of Financial Accounting
Standards No. 123, "Accounting for Stock Based Compensation," (SFAS123)
encourages, but does not require companies to record compensation cost for
stock based employee compensation plans at fair value. EEX has chosen to
continue to account for stock based compensation using the intrinsic value
method prescribed in Accounting Principles Board Opinion No. 25, "Accounting
for Stock Issued to Employees," and related Interpretations. Accordingly,
compensation cost for stock options is measured as the excess, if any, of the
quoted market price of EEX's stock at the date of the grant over the amount an
employee must pay to acquire the stock. The final compensation cost for
restricted stock awards is based on the quoted market price of EEX's stock at
the date the award becomes vested (See Note 9).
 
3. SUPPLEMENTAL CASH FLOW INFORMATION
 
  Cash paid for interest, net of amounts capitalized, was $23,422 in 1996,
$11,890 in 1995 and $20,248 in 1994. Net cash income taxes paid were $1,530 in
1996 and $6,011 in 1995.

4. MERGER WITH LONE STAR ENERGY PLANT OPERATIONS, INC.
 
  On April 15, 1996, ENSERCH announced that it had entered into a merger
agreement with Texas Utilities Company (TUC), subject to shareholder and
regulatory approval. The merger is to be preceded by the distribution of
ENSERCH's approximate 83% interest in EEX to the ENSERCH shareholders.
 
  In connection with this distribution, EEX will merge with Lone Star Energy
Plant Operations, Inc. (LSEPO), a subsidiary of ENSERCH. LSEPO operates and
maintains, under long term contracts, three cogeneration facilities. The value
of LSEPO was fixed at $7.0 million, which includes an ENSERCH working capital
guarantee of $3.5 million. The number of shares issued by the merged entity in
exchange for the outstanding LSEPO common stock will be determined by dividing
$7 million by the average of the closing sales price of EEX common stock for
the 15 trading days preceding the fifth trading day prior to the effective
time of the merger. An average market price for EEX shares of $9.00 per share
(778,000 shares) was assumed to determine the pro forma shares outstanding and
pro forma earnings per share of the combined entities.

                           ENSERCH EXPLORATION, INC.
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  On November 15, 1996, in separate meetings, the shareholders of TUC, ENSERCH
and EEX approved the mergers and the related distribution. All regulatory
approvals have been received except for the approval by the Securities and
Exchange Commission under the Public Utility Holding Company Act of 1935 where
the approval process is proceeding. The Antitrust Division of the U.S.
Department of Justice (DOJ) has notified ENSERCH and TUC that its
investigation of the proposed merger has been closed without the DOJ taking
any action or requiring ENSERCH or TUC to take any action. In a private letter
ruling, the Internal Revenue Service notified ENSERCH that neither ENSERCH nor
its shareholders will recognize taxable gain in the distribution of EEX stock.
 
  Following is a summary of pro forma combined results of operations of EEX
and LSEPO:

5. DALEN ACQUISITION
 
  On June 8, 1995, EEX acquired all the capital stock of DALEN Corporation
(DALEN) for cash of $340 million and assumed DALEN's bank debt of $115
million. The acquisition was accounted for as a purchase. The assets acquired
and the liabilities assumed were recorded at their estimated fair values.
Essentially all of the valuation adjustment was assigned to gas and oil
properties.
 
  Assuming the DALEN acquisition had occurred at the beginning of 1995, EEX
pro forma 1995 results of operations would include revenues of $269,175; an
operating loss of $5,746; a net loss of $22,201 and a net loss per share of
$0.20.
 
6. BORROWINGS AND CREDIT AGREEMENTS
 
  EEX has a $350 million revolving credit line with a group of banks that
matures on August 1, 2001, of which $235 million was unused at December 31,
1996. The revolving credit agreement limits, at all times, total debt, as
defined, to the lesser of 60% of capitalization, as defined, or $900 million,
and prohibits liens on property except under certain circumstances. The
interest rate ranges from the London Inter-Bank Offered Rate (LIBOR) (5.61% in
effect at December 31, 1996) plus .35% to .75% per annum, plus a facility fee
of from .15% to .25% per annum, depending upon the consolidated capitalization
ratio.
 
  EEX has a $50 million borrowing arrangement with ENSERCH to meet short term
cash needs. Under this arrangement, ENSERCH may advance funds to EEX, and EEX
may advance funds to ENSERCH. At December 31, 1996, EEX had a receivable from
ENSERCH of $13 million under this arrangement with interest based on LIBOR
(5.6% at December 31, 1996). This agreement will terminate upon the merger of
ENSERCH and TUC.

7. LEASE COMMITMENTS
 
  The equipment and facilities used in developing and producing reserves in
the Mississippi Canyon Block 441 and the Cooper Project were originally
financed under equipment leases between certain financial institutions and
EPO. In connection with the merger of EPO into EEX, the leases were assigned
to and assumed by Enserch Exploration Holdings, Inc. (EEH), wholly owned by
ENSERCH. EEX entered into three subleases with EEH for such offshore
facilities. For accounting purposes, one of the leases was an operating lease,
and two were capital leases.
 
  A component of the payments to be made by EEX under the subleases was based
on a floating interest rate of LIBOR plus 1.50% per annum. However, effective
November 1995, ENSERCH entered into an interest rate swap on a notional amount
of $150 million to fix its costs and agreed to fix the interest rate to EEX
accordingly at 7.2% (see Note 10).
 
  In October 1996, the Mississippi Canyon Block 441 equipment and facilities
were refinanced through certain financial institutions. EEX simultaneously
entered into a lease of the facilities which extends through October 2001. For
accounting purposes, this lease is classified as a capital lease. EEX has an
option to purchase the facilities for a fixed amount at the early buy-out date
of July 22, 2000, or for fair market value at the end of the lease term. There
are no renewal options. Interest on the lease was fixed at 6.97%.
 
  In December 1996, the Cooper Project equipment and facilities were
refinanced through certain financial institutions. EEX simultaneously entered
into two leases of the facilities extending through December 30, 2010, with
the option to renew the leases, with the consent of the lessors, for up to
five years. For accounting purposes, these leases are classified as capital
leases. The Company has the option to purchase the facilities for fair market
value on any renewal date, or for fixed amounts or fair market value at the
end of the initial lease term. The leases also contain two early buy-out
option dates on which the Company may purchase the facilities for fixed
amounts, and other special purchase options. Interest on the leases was fixed
at 6.51%. EEX is currently required to maintain a $65 million letter of credit
in support of the equity owners of the leased facilities.
 
  In June 1996, EEX entered into an operating lease arrangement to provide
financing for the offshore platform and related facilities of its 40% owned
Green Canyon 254 (Allegheny) project. The lessor will fund the construction
cost of the facilities quarterly, up to a maximum of $200 million. As of
December 31, 1996, a total of $18 million had been advanced to EEX under the
lease as agent for the lessor, $5.5 million of which was unexpended and
reflected as a current liability. EEX will lease the facilities for an initial
period through June 29, 2003, with the option to renew the lease, with the
consent of the lessor, for up to three successive three year periods. EEX, as
agent for the lessors, will acquire, construct, and operate the leased
property and has guaranteed completion of construction of the facilities. EEX
has the option to purchase the facilities at the end of the initial lease term
and has guaranteed an estimated residual value of approximately $160 million,
assuming the full lease amounts are advanced and expended, should the lease
not be renewed. Lease payments are being deferred during the construction
period and will be amortized when production begins.
 
  EEX also leases buildings and office space under noncancelable operating
leases that expire at various dates through 2002.

8. COMPANY-OBLIGATED MANDATORILY REDEEMABLE PREFERRED SECURITIES
 
  On August 4, 1995, a subsidiary (Issuer), whose common equity interests are
wholly owned by EEX Capital L.L.C. (Capital), a limited liability company
wholly owned by EEX, completed the private placement of $150 million of
adjustable rate mandatorily redeemable preferred securities. Issuer is a
special purpose finance subsidiary and neither Issuer nor Capital has
operations independent from EEX. The proceeds were loaned, under a Demand
Note, by Issuer to Capital. Capital used the proceeds to purchase preferred
stock from EEX and EEX repaid the bridge loan. In 1996 EEX repurchased at par
the fifteen shares held by Capital for $150 million through the issuance of a
demand note in that amount. This demand note is eliminated in consolidation.
Issuer's preferred securities are reflected on the balance sheet as "Company-
obligated mandatorily redeemable preferred securities of subsidiary." Interest
payments on the EEX demand note support the interest payments due under the
Demand Note loan agreement which, in turn, support the dividend requirements
of Issuer's preferred securities. Dividends on Issuer's preferred securities
are based on LIBOR plus 0.5% to 1.0% per annum and are reflected in interest
and other financing costs in the statements of consolidated operations. In
late 1995, EEX entered into an interest rate swap which effectively fixes the
rate for the dividend on these preferred securities at 6.37% as of December
31, 1996 (see Note 10). EEX has guaranteed Capital's obligations under the
Demand Note. The mandatory redemption date for Issuer's preferred securities
is the earlier of August 4, 2005 or the Demand Note repayment date.
 
9. STOCK PLANS
 
  The Company's Revised and Amended 1996 Stock Incentive Plan (the "Plan"),
provides for awards to officers, directors and key employees of restricted
stock, stock options to purchase shares of common stock of

EEX, or a combination of both. EEX has reserved 3,698,500 shares of its common
stock for issuance under the Plan. Options granted under the Plan have an
exercise price of not less than the fair market value of the common stock on
the grant date. Options become exercisable over four years and expire after
ten years. The terms for the release of restrictions on awards of restricted
stock may be performance based, time based, or a combination of both, and each
award may have different restrictions and conditions.

  The weighted average grant date fair value of restricted stock awarded
during 1996 was $9.36. Fair value is equal to the common stock fair market
value on the grant date. On September 10, 1996, the Board of Directors
approved the Preliminary Plan of Merger with LSEPO. As a result, all
restrictions on outstanding shares awarded prior to that date were lifted.
 
  In 1996 the Company adopted the Employee Stock Option Plan for eligible
employees not covered by the Plan described above. Stock options granted to
purchase shares of EEX common stock have an exercise price of not less than

1.3 million shares for issuance under this plan. Options become exercisable

Company granted 1,102,450 options at a weighted average exercise price of
$11.00. No options were exercised or canceled in 1996 and none were
exercisable at December 31, 1996. Exercise prices range from $10.69 to $11.25

  Total compensation cost recognized in income for 1996 and 1995 for stock

  The effects of applying SFAS123 in this pro forma disclosure are not
indicative of future amounts as additional awards in future years are
anticipated.
 
  The weighted average grant date fair value of options granted during 1996
was $4.72. Fair value of options was calculated by using the Black-Scholes
options pricing model using the following weighted average assumptions for
1996 activity: risk free interest rate of 6.17%, expected life of 6 years,
expected volatility of 37% and no dividend yield.
 
10. FINANCIAL INSTRUMENTS AND RISK MANAGEMENT
 
  The Company's operations involve managing market risks related to changes in
interest rates and commodity prices. Derivative financial instruments,
specifically swaps, futures, options and other contracts, are used to reduce
and manage those risks.
 
  Interest Rate Swaps--In November 1995, the Company entered into an interest
rate swap on a notional amount of $150 million to fix the interest rate
associated with the company-obligated mandatorily redeemable preferred
securities of subsidiary (see Note 8). The notional amount declines on a
schedule that parallels the estimated redemption of the securities and
terminates in July 2000. Under the swap agreement, EEX is to receive interest
on the outstanding notional amount at a rate (5.53% in effect at December 31,
1996) based on LIBOR, reset quarterly, and is to pay a fixed rate of 5.8%. The
net effect of the swap fixes the rate on the preferred dividends at 6.37% at
December 31, 1996. The Company is exposed to market risk under this swap
agreement due to the possibility of exchanging a lower interest rate for a
higher interest rate. The counter-parties are major financial institutions,
and the risk of incurring losses related to credit risk is considered by the
Company to be remote.
 
  In December 1996, in connection with the refinancing of the Cooper Project
leasing arrangements (See Note 7), the Company recognized a $1.4 million after
tax ($2.2 million pre-tax) gain on the settlement of the related interest rate
swap which had been in effect since December 1995 on a notional amount of $150
million.
 
  Commodity Hedging Activities--The Company enters into swaps, futures and
other derivative contracts to hedge the price risks associated with a portion
of anticipated future gas and oil production. Under these agreements, payments
are received or made based on the differential between a fixed and a variable
product price. These agreements are settled in cash at or prior to expiration
or exchanged for physical delivery contracts. The Company does not obtain
collateral to support the agreements but monitors the financial viability of
counter-parties and believes its credit risk is minimal on these transactions.
In the event of nonperformance by

                           ENSERCH EXPLORATION, INC.
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
counter-parties, the Company would be exposed to price risk. The Company has
some risk of accounting loss since the price received for the product at the
actual physical delivery point may differ from the prevailing price at the
delivery point required for settlement of the hedging transaction.
 
  Gas and oil hedging activities reduced revenues $20 million in 1996 and
increased revenues $.1 million and $4.3 million in 1995 and 1994,
respectively.
 
  At December 31, 1996, EEX had outstanding swaps, collars and futures
agreements that were entered into as hedges extending through December 31,
1997 to exchange payments on 32 Bcf of natural gas and 365 MBbls of oil. The
weighted average strike price and market price per Mcf of natural gas was
$2.47 and $2.37, respectively, and the weighted average strike price and
market price per barrel of oil was $25.00 and $25.32, respectively. At
December 31, 1996 there were $3.0 million of net unrealized and unrecognized
hedging gains based on the difference between the strike price and the New
York Mercantile Exchange futures price for the applicable trading month. In
addition, there were $5.1 million of realized losses on hedging activities
which were deferred and will be applied as a reduction in revenues in January
1997, the month of physical sale of production.
 
  Fair Value of Financial Instruments--At December 31, 1996, the estimated
proceeds the Company would have received to terminate or otherwise settle gas
and oil swaps, collars and futures agreements were $3.0 million and interest
rate swaps were $.9 million, which represented their fair value. The fair
value of all other financial instruments at December 31, 1996 and 1995,
including the revolving credit agreement and the company-obligated mandatorily
redeemable preferred securities of subsidiary, approximated carrying value.
 
11. INCOME TAXES
 
  For periods prior to 1995, except for international and SACROC operations,
the Company operated as a partnership, and the income or loss of the
partnership was includable in the tax returns of the individual partners.
Accordingly, no recognition was given to income taxes on partnership
operations. EEX, as a corporation, is a taxable entity; its operations are
included in ENSERCH's consolidated federal income tax return. Pursuant to a
tax sharing agreement, EEX and ENSERCH make or receive payments determined as
though EEX and its subsidiaries filed a separate consolidated federal income
tax return. The accompanying statements of operations for periods prior to
1995 include a pro forma provision for income taxes on the partnership
operations based on the applicable corporate federal statutory rate.

12. EMPLOYEE BENEFIT PLANS
 
  At December 31, 1996, substantially all employees were covered by an ENSERCH
pension plan, and some retirees are eligible for varying levels of health care
and life insurance benefits. Employees hired after July 1, 1989 are not
eligible for medical benefits when they retire. The allocation of the costs of
these plans is actuarially determined. As a result of ENSERCH's pending
distribution of EEX stock to ENSERCH Corporation shareholders (see Note 4),
the Company intends to establish new plans which will provide substantially
the same benefits as the ENSERCH plans.

  The assumed health care cost trend rate is 6.5% for 1996, declining
gradually to 4.5% after 1999, and remaining at that level thereafter. If the
health care cost trend rate were increased by 1%, the accumulated
postretirement benefit obligation of ENSERCH as of December 31, 1996 and the
net periodic postretirement benefit costs of ENSERCH for 1996 would be
increased by $4.2 million and $.3 million, respectively.
 
  Investment Plan--At December 31, 1996 ENSERCH provided a voluntary
contributory investment plan that was available to substantially all employees
of the Company. The Company's share of costs under the plan was

$425, $304 and $236 in 1996, 1995 and 1994, respectively. The Company intends
to establish a new plan with substantially the same provisions as the ENSERCH
plan.
 
13. RELATED PARTY TRANSACTIONS
 
  In the ordinary course of business, the Company engages in various
transactions with ENSERCH and its affiliates. The Company is charged for
direct costs incurred by ENSERCH Companies that are associated with managing
the Company's business and operations. Additionally, the Company is charged
for indirect costs including the general and administrative staff costs
incurred by ENSERCH in performing accounting, treasury, internal audit, income
tax planning and compliance, legal, information systems, human resources and
other functions. Prior to July 1, 1994, the Company was not charged for the
cost of ENSERCH elected officer management of these functions. Costs are
determined on a basis that reasonably reflects the actual costs of services
performed for EEX and may include allocations based on such factors as net
capital employed, the number of employees or the percentage of time spent on
projects or services. ENSERCH charges for all indirect costs amounted to
$4,510, $2,725 and $2,162 in 1996, 1995 and 1994, respectively. Effective
January 1, 1997 responsibility for all management and administrative functions
previously performed by ENSERCH, along with selected ENSERCH employees, were
transferred to EEX and the ENSERCH allocations were discontinued.
 
  The Company had sales to certain ENSERCH companies (Enserch Energy Services,
Inc., Lone Star Gas Company and Enserch Processing Company) that aggregated
$86,235, $87,002 and $110,036 in 1996, 1995 and 1994, respectively.
 
  EEX incurred interest costs, including amounts capitalized, of $72, $3,389
and $21,579 in 1996, 1995 and 1994, respectively, on borrowings from ENSERCH
Companies.
 
  Interest income on notes receivable from ENSERCH Companies was $66, $1,027
and $671 in 1996, 1995 and 1994, respectively.
 
  See Note 1 for information concerning transactions with ENSERCH companies in
connection with the organization of the Company and Note 7 for information
concerning lease transactions with affiliates.
 
14. CONTINGENT LIABILITIES
 
  Legal Proceedings--On March 23, 1994, a lawsuit was brought in the 299th
District Court of Harris County, Texas against EPO (the Company's predecessor)
and five other defendants by 19 royalty owners under leases contained within
the Corby Gas Unit in Leon County, Texas. Defendants are working interest
owners and lessees under the leases. The plaintiffs allege causes of action
involving breach of express and implied obligations under the leases,
drainage, failure to explore and develop for gas and oil under the leases,
civil conspiracy, tortious interference with contractual relationships,
specific performance, negligence and conversion. The plaintiffs seek to
recover alleged actual damages in excess of $5.4 million, punitive damages of
at least ten times the actual damages, if any, found by a jury, interest and
attorneys' fees. The Company owned a 7.1% interest in these leases.
 
  A lawsuit was filed against ENSERCH, its utility division, EPO and EPO's
managing general partner 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.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  A lawsuit was filed on February 24, 1987, in the 112th Judicial District of
Sutton County, Texas, against certain subsidiaries and affiliates of ENSERCH,
including predecessors of EEX. The plaintiffs initially 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. Under amended pleadings filed in January, 1997,
plaintiffs have added allegations of negligence and gross negligence in
connection with the measurement of gas, and conversion. 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 April 17, 1996, a subsidiary of EEX was made a third party defendant in a
lawsuit filed in the United States District Court for the Central Division of
Utah. The original suit was instituted to quiet title to an oil and gas lease
in Carbon County, Utah, which had been assigned to the plaintiffs by the
subsidiary. The defendants, previous assignees of the lease, are seeking
damages of $10 million from the subsidiary in the event the defendants lose
their rights to the lease.
 
  Management believes that the named defendants have meritorious defenses to
the claims made in these and other actions brought in the ordinary course of
business. In the opinion of management, the Company will incur no liability
from these and all other pending claims and suits that is material for
financial reporting purposes.
 
  Environmental Matters--The Company is subject to federal, state and local
environmental laws and regulations that regulate the discharge of materials
into the environment. Environmental expenditures are expensed or capitalized
depending on their future economic benefit. The level of future expenditures
for environmental matters, including costs of obtaining operating permits,
equipment monitoring and modifications under the Clean Air Act and cleanup
obligations, cannot be fully ascertained until the regulations that implement
the applicable laws have been approved and adopted. It is management's opinion
that all such costs, when finally determined, will not have a material adverse
effect on the consolidated financial position or results of operations of the
Company.

  Approximately 51% of excluded costs relates to offshore activities in the
Gulf of Mexico, about 45% is domestic onshore exploration activities and the

exploratory and development activities continue, which are 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.

Proved reserves for all periods were undeveloped.
 
  Standardized Measure of Discounted Future Net Cash Flows Relating to Proved
Gas and Oil Reserve Quantities (Unaudited)--has been prepared 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 and 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: Gas (per Mcf) $3.37 in 1996, $2.19 in 1995, and $2.29 in 1994; Oil (per
barrel) $23.33 in 1996, $16.91 in 1995, and $14.07 in 1994.

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

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

     Section 10. The Chairman and President shall preside at all meetings of
the shareholders.  In his absence, an officer of the corporation designated by
the Board of Directors shall preside and perform the duties of the Chairman and
President 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,
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,

                                       3
<PAGE>
 
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

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 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

                                       4
<PAGE>
 
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 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.

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 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.  If
the employment of an officer or employee of the corporation who is also a
Director of the corporation is terminated due to disability, retirement,
resignation, action of the Board or otherwise, then such person shall be deemed
to have contemporaneously tendered his or her resignation as a Director unless
otherwise determined by the Board of Directors.

     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

<PAGE>
 
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 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

of Incorporation or the Bylaws, exercise the authority of the Board of Directors

member or alternate members of such committee; or (12) altering or repealing any
resolution of the Board of Directors that by its terms provides that it shall
not be so amendable or repealable; and, unless such resolution designating a
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.

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 and President or, in the event of the inability of the Chairman and
President to act, the Corporate Secretary in like manner and on like notice on
the written request of two Directors. Neither the business to be transacted at,
nor 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
business and the act of a majority of the Directors present at any meeting at
which there is a quorum shall be the act of the Board of Directors.  Any action
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 signed by all members of the Board of Directors.  If a quorum shall
not be present at any meeting of Directors, the Directors present thereat may
adjourn the meeting from time to time, without notice other than announcement at
the meeting, until a quorum shall be present.

                                    NOTICES

     Section 1.  Whenever under the provisions of the statutes or of the
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
United States mails as aforesaid.

     Section 2.  Whenever any notice is required to be given to any shareholder
or Director of the corporation under the provisions of the statutes or of the
Articles of Incorporation, or of these Bylaws, a waiver thereof in writing
signed by the person or persons entitled to such notice, whether before or after
the time stated in such notice, shall be equivalent to the giving of 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 the meeting, of objecting to the transaction of any
business on the grounds that the meeting is not lawfully called or held.

                       RESTRICTIONS ON FOREIGN OWNERSHIP

     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
corporation or any interest therein or right thereof are or are to be held and
as to whether or not such persons are Eligible Citizens.

     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.

     Section 4. REDEMPTION. If at any time (i) the corporation is named, 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 the then
Current Market Price and upon such terms as shall be determined by the Board of
Directors, in their sole discretion.

                                       15

     Section 5. DEFINITIONS. "Current Market Price" per share of capital stock
of the corporation on any date is the average of the Quoted Prices of such class
of capital stock during the four trading weeks before the date in question. In
the absence of one or more such quotations, the Board of Directors shall
determine the current market price on the basis of such quotations as it
considers appropriate.

     "Eligible Citizen" means any person (including a corporation, partnership
or other entity) whose ownership, holding or control of shares in the
corporation would not, by reason of such person's citizenship or the citizenship
of its members or owners or otherwise, (1) disqualify the corporation or any of
its Subsidiaries from owning, acquiring, holding, possessing, or leasing oil,
gas or other minerals, mineral deposits, land, vessels or any 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, (2) violate any other
qualifications as the Board of Directors deems in its reasonable discretion are
necessary or appropriate to permit the corporation and its Subsidiaries to
engage in any other business activities for which there may be qualifications or
restrictions on shareholders of the corporation or any of its Subsidiaries
applicable under federal or state law. 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 or
otherwise qualifies as a United States citizen; (2) for a corporation, that is
organized or existing under the laws of the United States, a state, the District
of Columbia or 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 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,
the mean between the closing bid and asked prices for such shares as published
by NASDAQ or in the absence of any of the foregoing, the fair market value as
determined by the Board of Directors.

stock of which is owned by the corporation or any Subsidiary of the corporation.

rights of any nature whatsoever in federal lands or leases under federal laws

Agreement as provided in Section 12.06(b), to and up to, but excluding, the

                                       14
<PAGE>
 
Commitments.  Subject to the terms of this Agreement, during the period from the
Effective Date to and up to, but excluding, the Revolving Credit Termination
Date, any Obligor may borrow, repay and reborrow the amount described in this
Section 2.01.

   (b) Limitation on Types of Loans.  Subject to the other terms and provisions
of this Agreement, at the option of the Company, the Committed Loans may be Base
Rate Loans or Eurodollar Loans; provided that, without the prior written consent
of the Majority Lenders, no more than seven (7) Eurodollar Loans which are
Committed Loans to any or all Obligors by any Lender may be outstanding at any
time.

   Section 2.02  Borrowings, Continuations and Conversions of Committed Loans.

   (a) Borrowings.  An Obligor shall cause the Company to give the
Administrative Agent (which shall promptly notify the Lenders) advance notice as
hereinafter provided of each Borrowing of a Committed Loan hereunder, which
shall specify the name of the Obligor making such Borrowing; the aggregate
amount of such Borrowing, the Type and the date (which shall be a Business Day)
of the Committed Loans to be borrowed and (in the case of Eurodollar Loans) the
duration of the Interest Period therefor.

   (b) Minimum Amounts.  All Borrowings of Base Rate Loans shall be in amounts
of at least $10,000,000 or the remaining balance of the Aggregate Commitments,
if less, or any whole multiple of $1,000,000 in excess thereof, and all
Borrowings in the form of Eurodollar Loans shall be in amounts of at least
$10,000,000 or any whole multiple of $1,000,000 in excess thereof.

   (c) Notices.  All Borrowings, continuations and conversions of Committed
Loans shall require advance written notice to the Administrative Agent (which

Administrative Agent not later than 10:00 a.m. Central time on the Business Day
of each Base Rate Loan borrowing and three Business Days prior to the date of
each Eurodollar Loan borrowing, continuation or conversion.  Without in any way
limiting the Company's obligation to confirm in writing any telephonic notice,
the Administrative Agent may act without liability upon the basis of telephonic
notice believed by the Administrative Agent in good faith to be from the Company
prior to receipt of written confirmation.  In each such case, each Obligor
hereby waives the right to dispute the Administrative Agent's record of the
terms of such telephonic notice except in the case of gross negligence or
willful misconduct by the Administrative Agent.

                                       15

   (d) Continuation Options.  With respect to Committed Loans and subject to the
provisions made in this Section 2.02(d), the Company on behalf of an Obligor may
elect to continue all or any part of any Borrowing of Eurodollar Loans beyond
the expiration of the then current Interest Period relating thereto by giving
advance notice as provided in Section 2.02(c) to the Administrative Agent (which
shall promptly notify the Lenders) of such election, specifying the amount of
such Loan to be continued and the Interest Period therefor.  In the absence of
such a timely and proper election, the Company on behalf of an Obligor shall be
deemed to have elected to convert such Eurodollar Loan to a Base Rate Loan
pursuant to Section 2.02(e).  All or any part of any Eurodollar Loan may be
continued as provided herein, provided that (i) any continuation of any such
Loan shall be (as to each Borrowing as continued for an applicable Interest
Period) in amounts of at least $10,000,000 or any whole multiple of $1,000,000
in excess thereof and (ii) no Default shall have occurred and be continuing.  If
a Default shall have occurred and be continuing, each Eurodollar Loan shall be
converted to a Base Rate Loan on the last day of the Interest Period applicable
thereto.

   (e) Conversion Options.  With respect to Committed Loans, the Company on
behalf of an Obligor may elect to convert all or any part of any Eurodollar Loan
on the last day of the then current Interest Period relating thereto to a Base
Rate Loan by giving notice as provided in Section 2.02(c) to the Administrative
Agent (which shall promptly notify the Lenders) of such election.  Subject to
the provisions made in this Section 2.02(e), the Company on behalf of an Obligor
may elect to convert all or any part of any Base Rate Loan at any time and from
time to time to a Eurodollar Loan by giving advance notice as provided in
Section 2.02(c) to the Administrative Agent (which shall promptly notify the
Lenders) of such election.  All or any part of any outstanding Base Rate Loan
may be converted as provided herein, provided that (i) any conversion of any
Base Rate Loan into a Eurodollar Loan shall be (as to each such Borrowing into
which there is a conversion for an applicable Interest Period) in amounts of at
least $10,000,000 or any whole multiple of $1,000,000 in excess thereof and (ii)
no Default shall have occurred and be continuing.  If a Default shall have
occurred and be continuing, no Base Rate Loan may be converted into a Eurodollar
Loan.

   (f) Advances.  Not later than 1:00 p.m. (Central time) on the date
specified for each Borrowing hereunder, each Lender shall make available the
amount of the Committed Loan to be made by it on such date to the Administrative
Agent, to an account which the Administrative Agent shall specify, in
immediately available funds, for the account of the Company. The amounts so
received by the Administrative Agent shall, subject to the terms and conditions
of this Agreement, be made available to the Company on behalf of an Obligor by
depositing the same, in immediately available funds, in an account of the
Company, designated by the Company on behalf of an Obligor and maintained at the
Principal Office, or to be deposited at the direction of the Company on behalf
of an Obligor.

termination or reduction, which notice shall specify the effective date thereof

administration fee of $25,000.00 per annum payable on the Closing Date and each
anniversary of the Closing Date during the term of this Agreement.

   Section 2.05  Several Obligations.  The failure of any Lender to make any
Loan to be made by it on the date specified therefor shall not relieve any other
Lender of its obligation to make its Loan on such date, but no Lender shall be
responsible for the failure of any other Lender to make a Loan to be made by
such other Lender.

   Section 2.06  Notes.

   (a) The Committed Loans made by each Lender to an Obligor shall be evidenced

the principal

                                       17
<PAGE>
 
thereof, shall be recorded by such Lender on its books for its Committed Note,
and, prior to any transfer, endorsed by such Lender on the schedule attached to
such Committed Note or any continuation thereof.  Failure to make any such
notation shall not affect the Obligor's obligations in respect of such Loans, or
affect the validity of such transfer by any Lender of such Note.

   (b) The Competitive Loans made by each Lender to an Obligor shall be
evidenced by a single promissory note of such Obligor in substantially the form
of Exhibit B, dated (i) the Closing Date or (ii) the effective date of an
Assignment pursuant to Section 12.06(b) or (iii) the date that the Company

Interest Period of each Competitive Loan made by each Lender, and all payments
made on account of the principal thereof, shall be recorded by such Lender on
its books for its Competitive Note, and, prior to any transfer, endorsed by such
Lender on the schedule attached to such Competitive Note or any continuation
thereof.  Failure to make any such notation shall not affect the Obligor's
obligations in respect of such Loans, or affect the validity of such transfer by
any Lender of such Note.

   Section 2.07  Prepayments.

   (a) Any Obligor may prepay its Base Rate Loans upon prior notice to the
Administrative Agent (which shall promptly notify the Lenders), which notice

of the prepayment (which shall be at least $5,000,000 or any whole multiple of
$1,000,000 in excess thereof or the remaining aggregate principal balance
outstanding on the Notes) and shall be irrevocable and effective only upon
receipt by the Administrative Agent, provided that interest on the principal
prepaid, accrued to the prepayment date, shall be paid on the prepayment date.
Any Obligor may prepay its Eurodollar Loans and Fixed Rate Loans on the same
condition as for Base Rate Loans and in addition such prepayments of Eurodollar
Loans and Fixed Rate Loans shall be subject to the terms of Section 5.05 and
shall be in an amount equal to all of the Eurodollar Loans and Fixed Rate Loans
for such Obligor for the Interest Period prepaid.

   (b) If, after giving effect to any termination or reduction of the Aggregate
Commitments pursuant to Section 2.03, the outstanding aggregate principal amount
of the Loans exceeds the Aggregate Commitments, the Obligors shall prepay the
Loans on the date of such termination or reduction in an aggregate principal
amount equal to the excess, together with interest on the principal amount paid
accrued to the date of such prepayment.

   Section 2.09  Competitive Loans.

   (a) In accordance with the terms, conditions and procedures set forth in this
Section 2.09, the Company on behalf of any Obligor may on any Business Day prior
to the Revolving Credit Termination Date request Competitive Bids.

  (i)  Provided, however, no Lender shall be obligated to make Competitive Loans
to an Obligor unless such Lender has irrevocably offered to make such a
Competitive Loan pursuant to Section 2.09(c); and, provided, further, the
aggregate principal amount of all Competitive Loans to any or all Obligors at
any one time outstanding shall not, at any date, exceed an amount equal to (A)
the Aggregate Commitments as of such date, less (B) the aggregate principal
amount of the Committed Loans to any or all Obligors outstanding as of such
date.  For purposes of determining the amount to be calculated pursuant to the
foregoing sentence, any Committed Loans that the Company on behalf of an Obligor
has requested be made, which have not yet been made, shall be given effect as if
made in the full requested amount with respect thereto.

  (ii)  Notwithstanding the limitations on the aggregate amount of Competitive
Loans that the Obligors may borrow under this Agreement set forth in clause (i)
of this Section 2.09(a), the making of any Competitive Loan to an Obligor by any
Lender shall not be deemed to be a utilization of such Lender's Commitment
(although it shall be deemed to be a utilization of the Aggregate Commitments
for all purposes of this Agreement).

   (b) In order to request Competitive Bids, the Company on behalf of an Obligor
shall hand deliver, telex or telecopy to the Administrative Agent and the
Auction Agent a duly completed request substantially in the form of Exhibit C,
with the blanks appropriately completed (a "Competitive Bid Request"), to be

proposed Competitive Loan, and (ii) in the case of Fixed Rate Loans, not later
than 9:00 a.m. (Central time) one (1) Business Day before the date specified for
a proposed Competitive Loan.  No Base Rate Loan shall be requested in, or made
pursuant to, a Competitive Bid Request.  A Competitive Bid Request that does not
conform substantially to the format of Exhibit C may be rejected at the Auction
Agent's sole

                                       19
<PAGE>
 
discretion, and the Auction Agent shall promptly notify the Company of such
rejection by telex or telecopier.  Each Competitive Bid Request shall in each
case refer to this Agreement and specify (A) whether the Competitive Loans then
being requested are to be Eurodollar Loans or Fixed Rate Loans, (B) the date of
such Competitive Loans (which shall be a Business Day), (C) the aggregate
principal amount thereof (which shall not be less than $10,000,000 and shall be
an integral multiple of $1,000,000), and (D) the Interest Period with respect
thereto.  Promptly after its receipt of a Competitive Bid Request that is not
rejected as aforesaid, the Auction Agent shall invite by telex or telecopier (in
substantially the form set forth in Exhibit D) the Lenders to bid, on the terms
and conditions of this Agreement, to make Competitive Loans pursuant to such
Competitive Bid Request.  Notwithstanding the foregoing, the Auction Agent shall
have no obligation to invite any Lender to make a Competitive Bid pursuant to
this Section 2.09(b) until such Lender has delivered a properly completed
Competitive Bid Administrative Questionnaire to the Auction Agent.

   (c) Each Lender may, in its sole discretion, make one or more Competitive
Bids to an Obligor responsive to each Competitive Bid Request. Each Competitive
Bid by a Lender must be received by the Auction Agent via telex or telecopier,
in the form of Exhibit E, (i) in the case of Eurodollar Loans, not later than
8:30 a.m. (Central time) three (3) Business Days before the date specified for a
proposed Competitive Loan and (ii) in the case of Fixed Rate Loans, not later
than 8:30 a.m. (Central time) on the date specified for a proposed Competitive
Loan.  Competitive Bids that do not conform substantially to the format of
Exhibit E may be rejected by the Auction Agent after conferring with, and upon
the instruction of, the Company on behalf of an Obligor, and the Auction Agent
shall notify the applicable Lender of such rejection as soon as practicable.
Each Competitive Bid shall refer to this Agreement and (A) specify the principal
amount (which shall be in a minimum principal amount of $10,000,000 and in an
integral multiple of $1,000,000 and which may equal the entire aggregate
principal amount of the Competitive Loan requested by the Company on behalf of
an Obligor) of the Competitive Loan that the applicable Lender is willing to
make to such Obligor, (B) specify the Competitive Bid Rate at which such Lender
is prepared to make such Competitive Loan and (C) confirm the Interest Period
with respect thereto specified by the Company on behalf of an Obligor in its
Competitive Bid Request.  If any Lender shall elect not to make a Competitive
Bid, such Lender shall so notify the Auction Agent via telex or telecopier in
the case of Fixed Rate Loans, not later than 8:30 a.m. (Central time) on the
date of the proposed Competitive Loan and in the case of Eurodollar Loans, not
later than 8:30 a.m. (Central time) three (3) Business Days before the date
specified for a proposed Competitive Loan; provided, however, that failure by
any Lender to give such notice shall not cause such Lender to be obligated to
make any Competitive Loan.  A Competitive Bid submitted by a Lender pursuant to
this Subsection 2.09(c) shall be irrevocable.

                                       20
<PAGE>
 
   (d) The Auction Agent shall promptly notify the Company by telex or
telecopier of all the Competitive Bids made, the Competitive Bid Rate and the
maximum principal amount of each Competitive Loan in respect of which a
Competitive Bid was made and the identity of the Lender that made each
Competitive Bid.  The Auction Agent shall send a copy of all Competitive Bids to
the Company for its records as soon as practicable after completion of the
bidding process set forth in this Section 2.09.

   (e) The Company on behalf of an Obligor may in the sole and absolute
discretion of the applicable Obligor, subject only to the provisions of this
Section 2.09(e), accept or reject any Competitive Bid referred to in Section
2.09(d); provided, however, that the aggregate amount of the Competitive Bids so
accepted by the Company on behalf of an Obligor may not exceed the principal
amount of the Competitive Loan requested by the Company on behalf of an Obligor.
The Company on behalf of an Obligor shall notify the Auction Agent by telex or
telecopier whether and to what extent the Obligor has decided to accept or
reject any or all of the Competitive Bids referred to in Section 2.09(d), (i) in
the case of Eurodollar Loans, not later than 9:30 a.m. (Central time) three (3)
Business Days before the date specified for a proposed Competitive Loan, and
(ii) in the case of Fixed Rate Loans, not later than 9:30 a.m. (Central time) on
the date specified for a proposed Competitive Loan; provided, however, that (A)
the failure by the Company on behalf of an Obligor to give such notice shall be
deemed to be a rejection of all the Competitive Bids referred to in Section
2.03(c), (B) the Company on behalf of an Obligor shall not accept a Competitive
Bid made at a particular Competitive Bid Rate if the Company on behalf of an
Obligor has decided to reject a Competitive Bid made at a lower Competitive Bid
Rate, (C) if the Company on behalf of an Obligor shall accept Competitive Bids
made at a particular Competitive Bid Rate but shall be restricted by other
conditions hereof from borrowing the maximum principal amount of Competitive
Loans in respect of which Competitive Bids at such Competitive Bid Rate have
been made, then the Company on behalf of an Obligor shall accept a pro rata
portion of each Competitive Bid made at such Competitive Bid Rate based as
nearly as possible on the respective maximum principal amounts of Competitive
Loans for which such Competitive Bids were made and (D) no Competitive Bid shall
be accepted for a Competitive Loan unless such Competitive Loan is in a minimum
principal amount of $10,000,000 and an integral multiple of $1,000,000.
Notwithstanding the foregoing, if it is necessary for the Company on behalf of
an Obligor to accept a pro rata allocation of the Competitive Bids made in
response to a Competitive Bid Request (whether pursuant to the events specified
in clause (C) above or otherwise) and the available principal amount of
Competitive Loans to be allocated among the Lenders is not sufficient to enable
Competitive Loans to be allocated to each Lender in a minimum principal amount
of $10,000,000 and in integral multiples of $1,000,000, then the Company on
behalf of an Obligor shall select the Lenders to be allocated such Competitive
Loans and shall round allocations up or down to the next higher or lower
multiple of $1,000,000 as it shall deem appropriate.  In addition, the Company
on behalf of an Obligor shall

                                       21
<PAGE>
 
be permitted under the foregoing procedures to accept a Competitive Bid or
Competitive Bids in a principal amount of less than $10,000,000 (i) in order to
enable the Company on behalf of an Obligor to accept Competitive Bids equal to
(but not in excess of) the principal amount of the Competitive Loan requested by
the Company on behalf of an Obligor or (ii) in order to enable the Company on
behalf of an Obligor to accept all remaining Competitive Bids, or all remaining
Competitive Bids at a particular Competitive Bid Rate.  A notice given by the
Company on behalf of an Obligor pursuant to this Subsection (e) shall be
irrevocable.

   (f) The Auction Agent shall promptly notify each bidding Lender by telex or
telecopy whether or not its Competitive Bid has been accepted (and if so, in
what amount and at what Competitive Bid Rate). Each successful bidder will
thereupon become bound, subject to the other applicable conditions hereof, to
make the Competitive Loan in respect of which its Competitive Bid has been
accepted.  After completing the notifications referred to in the immediately
preceding sentence, the Auction Agent shall notify each Lender and the
Administrative Agent of the aggregate principal amount of all Competitive Bids
accepted.

   (g) Upon receipt from the Administrative Agent of the notice of Eurodollar
Rate applicable to any Eurodollar Loan to be made by any Lender pursuant to a
Competitive Bid that has been accepted by the Company on behalf of an Obligor
pursuant to Section 2.03(e), the Auction Agent shall notify such Lender of (i)
the applicable Eurodollar Rate and (ii) the sum of the applicable Eurodollar
Rate plus the Margin bid by such Lender.

   (h) No Competitive Loan shall be made within five (5) Business Days of the
date of any other Competitive Loan, unless the Company and the Auction Agent
shall mutually agree otherwise.

   (i) If the Auction Agent shall at any time have a Commitment hereunder and
shall elect to submit a Competitive Bid in its capacity as a Lender, it shall
submit such Competitive Bid directly to the Company on behalf of an Obligor one
quarter of an hour earlier than the time at which the other Lenders are required
to submit their Competitive Bids to the Auction Agent pursuant to Section
2.09(c).

   (j) All notices required by this Section 2.09 shall be made in accordance
with Section 12.02 and the Competitive Bid Administrative Questionnaire most
recently placed on file by each Lender with the Auction Agent.

   (k) No Competitive Loan may be continued or converted, except to the extent
converted to a Base Rate Loan pursuant to Section 5.04; provided, however, a
Competitive Loan may be repaid with the proceeds of a Borrowing of Competitive
Loans or Committed Loans made pursuant to the terms of this Agreement, and the
Administrative Agent is authorized to net the Borrowing and repayments for
convenience.

                                       22
<PAGE>
 
   (l) Not later than 12:00 noon (Central time) on the date specified for each
Borrowing hereunder, each Lender that is a successful bidder shall make
available the amount of the Competitive Loan to be made by it on such date to
the Administrative Agent, to an account which the Administrative Agent shall
specify, in immediately available funds, for the account of the Company on
behalf of an Obligor.  The amounts so received by the Administrative Agent
shall, subject to the terms and conditions of this Agreement, be made available
to the Company on behalf of an Obligor by depositing the same, in immediately
available funds, in an account of the Company on behalf of an Obligor,
designated by the Company on behalf of an Obligor and maintained at the
Principal Office.

   Section 2.10  Designated Subsidiaries.  The Company may from time to time
designate one or more of its Subsidiaries to have the right to borrow both
Committed Loans and Competitive Loans by sending to the Administrative Agent a
Notice of Designation of a Designated Subsidiary and otherwise complying with
Section 6.03.  Each Designated Subsidiary shall be liable for (i) the principal
and interest on Loans made to it as requested in any Borrowing Request or
Competitive Bid Requests signed by it or the Company on its behalf, (ii) all
fees, indemnities and reimbursement obligations as set forth in this Agreement
and (iii) to the extent the Designated Subsidiary is a Guarantor pursuant to
Section 8.08, the obligations set forth in its Subsidiary Guaranty Agreement. No
Designated Subsidiary shall be liable for any principal or interest on any Loan
to another Obligor except to the extent that such Designated Subsidiary is a
Guarantor pursuant to Section 8.08.  The Company shall be liable for all
Indebtedness of all Obligors as set forth either in this Agreement or the Parent
Guaranty Agreement.  As agreed to in each Notice of Designation of Designated
Subsidiary executed and delivered by the Company and each Designated Subsidiary,
each Designated Subsidiary appoints the Company as its agent to execute all
Borrowing Requests and Competitive Bid Requests, give and receive all notices on
its behalf and take whatever other action is required of it under the Loan
Documents, and the Agents and Lenders are entitled to fully rely on all action
taken and notices given by the Company on behalf of any Designated Subsidiary.

                                  ARTICLE III

                      PAYMENTS OF PRINCIPAL AND INTEREST

   Section 3.01  Repayment of Loans.  Each Obligor will pay to the
Administrative Agent, for the account of each applicable Lender, the principal
payments required by this Section 3.01.  On the last day of the Interest Period
for each Competitive Loan to an Obligor, such Obligor shall repay the
outstanding aggregate principal and accrued and unpaid interest on such Loan. On
the Revolving Credit Termination Date each Obligor shall repay the outstanding
aggregate principal and accrued and unpaid interest under its Notes.

                                       23
<PAGE>
 
   Section 3.02  Interest.  Each Obligor will pay to the Administrative Agent,
for the account of each Lender, interest on the unpaid principal amount of each
Loan made by such Lender to such Obligor for the period commencing on the date
such Loan is made to but excluding the date such Loan shall be paid in full, at
the following rates per annum:

   (a) if such Loan is a Committed Loan and a Base Rate Loan, the Base Rate (as
in effect from time to time), but in no event to exceed the Highest Lawful Rate;

   (b) if such Loan is a Committed Loan and a Eurodollar Loan, for each Interest
Period relating thereto, the Eurodollar Rate for such Loan plus the Applicable
Margin, but in no event to exceed the Highest Lawful Rate;

   (c) if such Loan is a Competitive Loan and a Eurodollar Loan, for each
Interest Period relating thereto, the Eurodollar Rate for such Loan plus or
minus the Margin as accepted by the Company on behalf of an Obligor, but in no
event to exceed the Highest Lawful Rate; and

   (d) if such Loan is a Competitive Loan and a Fixed Rate Loan, for each
Interest Period relating thereto, the fixed rate per annum offered by the
respective Lender in its Competitive Bid and accepted by the Company on behalf
of an Obligor pursuant to Section 2.09, but in no event to exceed the Highest
Lawful Rate.

Notwithstanding the foregoing, each Obligor will pay to the Administrative
Agent, for the account of each applicable Lender interest at the applicable
Post-Default Rate on any principal of any Loan made by such Lender to such
Obligor, which shall not be paid in full when due (whether at stated maturity,
by acceleration or otherwise), for the period commencing on the due date thereof
until the same is paid in full.  To the fullest extent permitted by law, each
Obligor will pay to the Administrative Agent for the account of each applicable
Lender interest at the Base Rate on interest and any other amount payable by
such Obligor hereunder other than principal on the Loans, under any other Loan
Document or under any Note held by such Lender to or for the account of such
Lender, which shall not be paid in full when due (whether at stated maturity, by
acceleration or otherwise), for the period commencing on the due date thereof
until the same is paid in full.

    Accrued interest on Base Rate Loans shall be payable on each Quarterly Date
commencing on June 30, 1995, and accrued interest on each Eurodollar Loan and
Fixed Rate Loan shall be payable on the last day of the Interest Period therefor
and, if such Interest Period is longer than three months at three-month
intervals following the first day of such Interest Period, except that interest
payable at the Post-Default Rate or otherwise accruing on past due amounts shall
be payable from time to time on demand and interest on any Eurodollar Loan or
Fixed Rate Loan that is converted into a Base Rate Loan (pursuant to Section
5.04) shall be payable on the date of conversion (but only to the extent so
converted).

                                       24
<PAGE>
 
   Promptly after the determination of any interest rate provided for herein or
any change therein, the Administrative Agent or the Auction Agent shall notify
the Lenders to which such interest is payable and the Company thereof. Each
determination by the Administrative Agent or the Auction Agent of an interest
rate or fee hereunder shall, except in cases of manifest error, be final,
conclusive and binding on the parties.

                                  ARTICLE IV

               PAYMENTS; PRO RATA TREATMENT; COMPUTATIONS; ETC.

   Section 4.01  Payments.  Except to the extent otherwise provided herein, all
payments of principal, interest and other amounts to be made by each Obligor
under this Agreement and the Notes shall be made in Dollars, in immediately
available funds, to the Administrative Agent at such account as the
Administrative Agent shall specify by notice to the Company on behalf of each
Obligor from time to time, not later than 1:00 p.m. (Central time) on the date
on which such payments shall become due (each such payment made after such time
on such due date to be deemed to have been made on the next succeeding Business
Day).  Such payments shall be made without (to the fullest extent permitted by
applicable law) defense, set-off or counterclaim.  Each payment received by the
Administrative Agent under this Agreement or any Note for the account of a
Lender shall be paid promptly to such Lender in immediately available funds. If
the due date of any payment under this Agreement or any Note would otherwise
fall on a day which is not a Business Day such date shall be extended to the
next succeeding Business Day and interest shall be payable for any principal so
extended for the period of such extension.  At the time of each payment to the
Administrative Agent of any principal of or interest on any Borrowing, the
Company on behalf of the Obligors shall notify the Administrative Agent of the
Loans to which such payment shall apply.  In the absence of such notice the
Administrative Agent may specify the Loans to which such payment shall apply,
but to the extent possible such payment or prepayment will be applied first to
the Loans comprised of Base Rate Loans.

   Section 4.02  Pro Rata Treatment.  Except to the extent otherwise provided
herein each Lender agrees that:  (i) each Borrowing from the Lenders under
Section 2.01 shall be made from the Lenders pro rata in accordance with their
Percentage Share, each payment of facility fees under Section 2.04(a) shall be
made for the account of the Lenders pro rata in accordance with their Percentage
Share, and each termination or reduction of the amount of the Aggregate
Commitments under Section 2.03(a) shall be applied to the Commitment of each
Lender, pro rata according to the amounts of its respective Commitment; (ii)
each payment of principal of Loans by the Company on behalf of an Obligor shall
be made for the account of the Lenders pro rata in accordance with the
respective unpaid principal amount of the Loans held by the Lenders due or past
due on such date or intended to be prepaid by the Company on behalf of such
Obligor;  and (iii) each payment of interest on Loans by the Company on behalf
of an Obligor shall be

                                       25
<PAGE>
 
made for the account of the Lenders pro rata in accordance with the amounts of
interest due and payable to the respective Lenders.

   Section 4.03  Computations.  Interest on Eurodollar Loans and Fixed Rate
Loans shall be computed on the basis of a year of 360 days and actual days
elapsed (including the first day but excluding the last day) occurring in the
period for which such interest is payable, unless such calculation would exceed
the Highest Lawful Rate, in which case interest shall be calculated on the per
annum basis of a year of 365 or 366 days, as the case may be.  Interest on Base
Rate Loans and fees shall be computed on the basis of a year of 365 or 366 days,
as the case may be, and actual days elapsed (including the first day but
excluding the last day) occurring in the period for which such interest or fee
is payable.

   Section 4.04  Non-receipt of Funds by the Administrative Agent. Unless the
Administrative Agent shall have been notified by a Lender or the Company on
behalf of an Obligor prior to the date on which such notifying party is
scheduled to make payment to the Administrative Agent (in the case of a Lender)
of the proceeds of a Loan to be made by it hereunder or (in the case of an
Obligor) a payment to the Administrative Agent for the account of one or more of
the Lenders hereunder (such payment being herein called the "Required Payment"),
which notice shall be effective upon receipt, that it does not intend to make
the Required Payment to the Administrative Agent, the Administrative Agent may
assume that the Required Payment has been made and may, in reliance upon such
assumption (but shall not be required to), make the amount thereof available to
the intended recipient(s) on such date and, if such Lender or the Company on
behalf of an Obligor (as the case may be) has not in fact made the Required
Payment to the Administrative Agent, the recipient(s) of such payment shall, on
demand, repay to the Administrative Agent the amount so made available together
with interest thereon in respect of each day during the period commencing on the
date such amount was so made available by the Administrative Agent until but
excluding the date the Administrative Agent recovers such amount at a rate per
annum which, for any Lender as recipient, will be equal to the Federal Funds
Rate, and for an Obligor as recipient, will be equal to the Post-Default Rate.

   Section 4.05  Sharing of Payments, Etc.  If after an Event of Default and
during its continuance any Lender shall obtain payment of any principal of or
interest on any Loan made by it to an Obligor under this Agreement through
whatever means other than an assignment pursuant to Section 12.06(b), and, as a
result of such payment, such Lender shall have received a greater percentage of
the principal or interest then due hereunder by such Obligor to such Lender than
the percentage received by any other Lenders, it shall promptly (i) notify the
Administrative Agent and each other Lender thereof and (ii) purchase from such
other Lenders participations in (or, if and to the extent specified by such
Lender, direct interests in) the Loans made by such other Lenders (or in
interest due thereon, as the case may be) in such amounts, and make such other
adjustments from time to time as shall be equitable, to the end that all the
Lenders shall share the benefit of such excess payment (net of any expenses
which may be incurred by such Lender in obtaining or preserving such excess
payment) pro rata in accordance with

                                       26
<PAGE>
 
the unpaid principal and/or interest on the Loans to such Obligor held by each
of the Lenders.  To such end all the Lenders shall make appropriate adjustments
among themselves (by the resale of participations sold or otherwise) if such
payment is rescinded or must otherwise be restored.

   Section 4.06  Taxes.

   (a) Payments Free and Clear.  Any and all payments by an Obligor hereunder
shall be made, in accordance with Section 4.01, free and clear of and without
deduction for any and all present or future taxes, levies, imposts, deductions,
charges or withholdings, and all liabilities with respect thereto, excluding, in
the case of each Lender and the Administrative Agent, taxes imposed on its
income, and franchise or similar taxes imposed on it, by (i) any jurisdiction
(or political subdivision thereof) of which the Administrative Agent or such
Lender, as the case may be, is a citizen or resident or in which such Lender has
an Applicable Lending Office, (ii) the jurisdiction (or any political
subdivision thereof) in which the Administrative Agent or such Lender is
organized, or (iii) any jurisdiction (or political subdivision thereof) in which
such Lender or the Administrative Agent is presently doing business which taxes
are imposed solely as a result of doing business in such jurisdiction (all such
non-excluded taxes, levies, imposts, deductions, charges, withholdings and
liabilities being hereinafter referred to as "Taxes").  If an Obligor shall be
required by law to deduct any Taxes from or in respect of any sum payable
hereunder to the Lenders or the Administrative Agent (i) the sum payable shall
be increased by the amount necessary so that after making all required
deductions (including deductions applicable to additional sums payable under
this Section 4.06) such Lender or the Administrative Agent (as the case may be)
shall receive an amount equal to the sum it would have received had no such
deductions been made, (ii) such Obligor shall make such deductions and (iii)
such Obligor shall pay the full amount deducted to the relevant taxing authority
or other Governmental Authority in accordance with applicable law.

   (b) Other Taxes.  In addition, to the fullest extent permitted by applicable
law, each Obligor agrees to pay any present or future stamp or documentary taxes
or any other excise or property taxes, charges or similar levies that arise from
any payment made hereunder or from the execution, delivery or registration of,
or otherwise with respect to, this Agreement, any Assignment or any other Loan
Document (hereinafter referred to as "Other Taxes").

   (c) INDEMNIFICATION.  TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, EACH
OBLIGOR WILL INDEMNIFY EACH LENDER AND THE AGENTS FOR THE FULL AMOUNT OF TAXES
AND OTHER TAXES (INCLUDING, BUT NOT LIMITED TO, ANY TAXES OR OTHER TAXES IMPOSED
BY ANY GOVERNMENTAL AUTHORITY ON AMOUNTS PAYABLE UNDER THIS SECTION 4.06) PAID
BY SUCH LENDER OR ANY AGENT (ON THEIR BEHALF OR ON BEHALF OF ANY LENDER), AS THE
CASE MAY BE, AND ANY LIABILITY (INCLUDING PENALTIES, INTEREST AND EXPENSES)
ARISING THEREFROM OR WITH RESPECT

                                       27
<PAGE>
 
   THERETO, WHETHER OR NOT SUCH TAXES OR OTHER TAXES WERE CORRECTLY OR LEGALLY
ASSERTED UNLESS THE PAYMENT OF SUCH TAXES WAS NOT CORRECTLY OR LEGALLY ASSERTED
AND SUCH LENDER'S PAYMENT OF SUCH TAXES OR OTHER TAXES WAS THE RESULT OF ITS
GROSS NEGLIGENCE OR WILLFUL MISCONDUCT.  ANY PAYMENT PURSUANT TO SUCH
INDEMNIFICATION SHALL BE MADE WITHIN THIRTY (30) DAYS AFTER THE DATE ANY LENDER
OR ANY AGENT, AS THE CASE MAY BE, MAKES WRITTEN DEMAND THEREFOR.  IF ANY LENDER
OR ANY AGENT RECEIVES A REFUND OR CREDIT IN RESPECT OF ANY TAXES OR OTHER TAXES
FOR WHICH SUCH LENDER OR SUCH AGENT HAS RECEIVED PAYMENT FROM AN OBLIGOR IT
SHALL PROMPTLY NOTIFY THE COMPANY ON BEHALF OF SUCH OBLIGOR OF SUCH REFUND OR
CREDIT AND SHALL, IF NO DEFAULT HAS OCCURRED AND IS CONTINUING, WITHIN THIRTY
(30) DAYS AFTER RECEIPT OF A REQUEST BY THE COMPANY ON BEHALF OF SUCH OBLIGOR
(OR PROMPTLY UPON RECEIPT, IF THE COMPANY ON BEHALF OF SUCH OBLIGOR HAS
REQUESTED APPLICATION FOR SUCH REFUND OR CREDIT PURSUANT HERETO), PAY AN AMOUNT
EQUAL TO SUCH REFUND OR CREDIT TO THE COMPANY ON BEHALF OF SUCH OBLIGOR WITHOUT
INTEREST (BUT WITH ANY INTEREST SO REFUNDED OR CREDITED), PROVIDED THAT SUCH
OBLIGOR, UPON THE REQUEST OF SUCH LENDER OR SUCH AGENT, AGREES TO RETURN SUCH
REFUND OR CREDIT (PLUS PENALTIES, INTEREST OR OTHER CHARGES) TO SUCH LENDER OR
SUCH AGENT IN THE EVENT SUCH LENDER OR SUCH AGENT IS REQUIRED TO REPAY SUCH
REFUND OR CREDIT.

   (d)  Lender Representations.

  (i) Each Lender represents that it is either (i) a corporation organized under
the laws of the United States of America or any state thereof or (ii) it is
entitled to complete exemption from United States withholding tax imposed on or
with respect to any payments, including fees, to be made to it pursuant to this
Agreement (A) under an applicable provision of a tax convention to which the
United States of America is a party or (B) because it is acting through a
branch, agency or office in the United States of America and any payment to be
received by it hereunder is effectively connected with a trade or business in
the United States of America.  Each Lender that is not a corporation organized
under the laws of the United States of America or any state thereof agrees to
provide to the Company and the Administrative Agent on the Closing Date, or on
the date of its delivery of the Assignment pursuant to which it becomes a
Lender, and at such other times as required by United States law or as the
Company or the Administrative Agent shall reasonably request, two accurate and
complete original signed copies of either (A) Internal Revenue Service Form 4224
(or successor form) certifying that all payments to be made to it hereunder will
be effectively connected to a United States trade or business (the "Form 4224
Certification") or (B) Internal Revenue Service Form 1001 (or successor form)
certifying that it is entitled to the benefit of a provision of a tax convention
to which the United States of America is a party which completely exempts from
United States withholding tax all payments to be made to it hereunder (the "Form
1001

                                       28
<PAGE>
 
   Certification").  In addition, each Lender agrees that if it previously filed
a Form 4224 Certification, it will deliver to the Company and the Administrative
Agent a new Form 4224 Certification prior to the first payment date occurring in
each of its subsequent taxable years; and if it previously filed a Form 1001
Certification, it will deliver to the Company and the Administrative Agent a new
certification prior to the first payment date falling in the third year
following the previous filing of such certification.  Each Lender also agrees to
deliver to the Company and the Administrative Agent such other or supplemental
forms as may at any time be required as a result of changes in applicable law or
regulation in order to confirm or maintain in effect its entitlement to
exemption from United States withholding tax on any payments hereunder, provided
that the circumstances of such Lender at the relevant time and applicable laws
permit it to do so.  If a Lender determines, as a result of any change in either
(i) a Governmental Requirement or (ii) its circumstances, that it is unable to
submit any form or certificate that it is obligated to submit pursuant to this
Section 4.06, or that it is required to withdraw or cancel any such form or
certificate previously submitted, it shall promptly notify the Company and the
Administrative Agent of such fact.  If a Lender is organized under the laws of a
jurisdiction outside the United States of America, unless the Company and the
Administrative Agent have received a Form 1001 Certification or Form 4224
Certification satisfactory to them indicating that all payments to be made to
such Lender hereunder are not subject to United States withholding tax, the
Company on behalf of each Obligor shall withhold taxes from such payments at the
applicable statutory rate. Each Lender agrees to indemnify and hold harmless
from any United States taxes, penalties, interest and other expenses, costs and
losses incurred or payable by (i) the Administrative Agent as a result of such
Lender's failure to submit any form or certificate that it is required to
provide pursuant to this Section 4.06 or (ii) the Company or the Administrative
Agent as a result of their reliance on any such form or certificate which such
Lender has provided to them pursuant to this Section 4.06.

  (ii) For any period with respect to which a Lender required to do so has
failed to provide the Company with the form required pursuant to this Section
4.06, if any (other than if such failure is due to a change in a Governmental
Requirement occurring subsequent to the date on which a form originally was
required to be provided), such Lender shall not be entitled to indemnification
under Section 4.06 with respect to taxes imposed by the United States which
taxes would not have been imposed but for such failure to provide such forms;
provided, however, that should a Lender, which is otherwise exempt from or
subject to a reduced rate of withholding tax, becomes subject to taxes because
of its failure to deliver a form required hereunder, the Company on behalf of
each Obligor shall take such steps as such Lender shall reasonably request to
assist such Lender to recover such taxes.

                                       29
<PAGE>
 
   (iii) Any Lender claiming any additional amounts payable pursuant to this
Section 4.06 shall use reasonable efforts (consistent with legal and regulatory
restrictions) to file any certificate or document requested by the Company or
the Administrative Agent or to change the jurisdiction of its Applicable Lending
Office or to contest any tax imposed if the making of such a filing or change or
contesting such tax would avoid the need for or reduce the amount of any such
additional amounts that may thereafter accrue and would not, in the sole
determination of such Lender, be otherwise disadvantageous to such Lender.

                                   ARTICLE V

                   CAPITAL ADEQUACY, ADDITIONAL COSTS, ETC.

   Section 5.01  Additional Costs.

   (a) Regulatory Changes.  In the event of any introduction of and/or any
change in any applicable law, rule, regulation (including Regulation D),
official interpretation thereof or official directive after the date of this
Agreement (whether or not having the force of law) which will result in an
increase in the cost to any Lender of making or maintaining the Loans by reason
of reserve or similar requirements, or which will result in a reduction of
amounts otherwise receivable by any Lender from any Obligor of principal,
interest or other fees and charges thereunder by reason of a tax, levy, impost,
fee, charge, withholding or similar requirements of any kind, or modifies any
capital adequacy or similar requirement (including, without limitation, a
requirement which affects any Lender's or its parent's or its holding company's
allocation of capital resources to its obligations or commitments) and, as a
result, the cost to such Lender or its parent or holding company of making or
maintaining amounts available under this Agreement is increased or the Lender's
or its parent's or holding company's return under this Agreement or on all or
any of its capital is reduced, the Obligors will pay to the Administrative Agent
for such Lender upon notice as provided in Section 5.01(b) an amount equal to
such actual increased cost or reduction of yield allocable to this facility.

   (b) Compensation Procedure.  Any Lender notifying the Company of the
incurrence of additional costs under this Section 5.01 shall in such notice to
the Company and the Administrative Agent set forth in reasonable detail the
basis and amount of its request for compensation.  Determinations and
allocations by each Lender for purposes of this Section 5.01 of the effect of
any Regulatory Change pursuant to Section 5.01(a) on its costs or rate of return
of maintaining Loans or its obligation to make Loans, or on amounts receivable
by it in respect of Loans, and of the amounts required to compensate such Lender
under this Section 5.01, shall be conclusive and binding for all purposes,
provided that such determinations and

                                       30
<PAGE>
 
allocations are made on a reasonable basis.  Any request for additional
compensation under this Section 5.01 shall be paid by each Obligor to the
Administrative Agent for the applicable Lender within thirty (30) days of the
receipt by the Company of the notice described in this Section 5.01(b).

   Section 5.02  Limitation on Eurodollar Loans.  Anything herein to the
contrary notwithstanding, if, on or prior to the determination of any Eurodollar
Rate for any Interest Period:

   (i) the Administrative Agent determines (which determination shall be
conclusive, absent manifest error) that quotations of interest rates for the
relevant deposits referred to in the definition of "Eurodollar Rate" in Section
1.02 are not being provided in the relevant amounts or for the relevant
maturities for purposes of determining rates of interest for Eurodollar Loans as
provided herein; or

   (ii) the Administrative Agent determines (which determination shall be
conclusive, absent manifest error) that the relevant rates of interest referred
to in the definition of "Eurodollar Rate" in Section 1.02 upon the basis of
which the rate of interest for Eurodollar Loans for such Interest Period is to
be determined are not sufficient to adequately cover the cost to the Lenders of
making or maintaining Eurodollar Loans;

then the Administrative Agent shall give the Company prompt notice thereof, and
so long as such condition remains in effect, the Lenders shall be under no
obligation to make additional Eurodollar Loans or continue or convert into
Eurodollar Loans.

   Section 5.03  Illegality.  Notwithstanding any other provision of this
Agreement, in the event that it becomes unlawful or legally restricted for any
Lender or its Applicable Lending Office to honor its obligation to make or
maintain, continue or convert into Eurodollar Loans or Fixed Rate Loans
hereunder, then such Lender shall promptly notify the Company thereof and such
Lender's obligation to make, continue or convert into Eurodollar Loans or Fixed
Rate Loans shall be suspended until such time as such Lender may again make and
maintain, continue or convert into Eurodollar Loans or Fixed Rate Loans (in
which case the provisions of Section 5.04 shall be applicable).

   Section 5.04  Base Rate Loans Pursuant to Sections 5.02 and 5.03.  If the
obligation of any Lender to make, continue or convert into Eurodollar Loans or
Fixed Rate Loans shall be suspended pursuant to Sections 5.02 or 5.03 ("Affected
Loans"), all Affected Loans which would otherwise be made by such Lender shall
be made instead as Base Rate Loans (and, if an event referred to in Section 5.03
has occurred and such Lender so requests by notice to the Administrative Agent
and the Company, all Affected Loans of such Lender then outstanding shall be
automatically converted into Base Rate Loans on the date specified by such
Lender in such notice) and, to the extent that Affected Loans are so made as (or
converted into) Base Rate Loans, all payments of principal which would

                                       31
<PAGE>
 
otherwise be applied to such Lender's Affected Loans shall be applied instead to
its Base Rate Loans.

   Section 5.05  Compensation.  Each Obligor shall pay to the Administrative
Agent for each Lender within thirty (30) days of receipt of written request of
such Lender to the Administrative Agent and the Company (which request shall set
forth, in reasonable detail, the basis for requesting such amounts and which
shall be conclusive and binding for all purposes provided that such
determinations are made on a reasonable basis), such amount or amounts as shall
compensate it for any loss, cost, expense or liability which such Lender
determines are attributable to:

   (i) any payment, prepayment or conversion of a Eurodollar Loan or Fixed Rate
Loan properly made by such Lender or such Obligor for any reason (including,
without limitation, the acceleration of the Loans pursuant to Section 10.01) on
a date other than the last day of the Interest Period for such Loan; or

   (ii) any failure by such Obligor for any reason (including but not limited
to, the failure of any of the conditions precedent specified in Article VI to be
satisfied) to borrow, continue or convert into a Eurodollar Loan that is a
Committed Loan or to borrow a Competitive Loan from such Lender on the date for
such Borrowing, continuation or conversion specified in the relevant notice
given pursuant to Section 2.02 or Section 2.09.

                                  ARTICLE VI

                             CONDITIONS PRECEDENT

   Section 6.01  Initial Funding.

   The obligation of the Lenders to make the Initial Funding is subject to the
receipt by the Administrative Agent and the Lenders of all fees payable pursuant
to Section 2.04 on or before the Closing Date and the receipt by the
Administrative Agent of the following documents and satisfaction of the other
conditions provided in this Section 6.01:

   (a) A certificate of the Secretary or an Assistant Secretary of the Company
setting forth (i) resolutions of its board of directors with respect to the
authorization of the Company to execute and deliver the Loan Documents to which
it is a party and to enter into the transactions contemplated in those
documents, (ii) the officers of the Company (y) who are authorized to sign the
Loan Documents to which the Company is a party and (z) who will, until replaced
by another officer or officers duly authorized for that purpose, act as its

                        REPRESENTATIONS AND WARRANTIES

   The Company represents and warrants to the Administrative Agent and the
Lenders that (each representation and warranty herein is given as of the Closing
Date and shall be deemed repeated and reaffirmed on the dates of each Borrowing
as provided in Section 6.02):

   Section 7.01  Corporate Existence.  Each of the Company and each Designated
Subsidiary and each Subsidiary Guarantor:  (i) is a corporation duly organized,
legally existing and in good standing under the laws of the jurisdiction of its
incorporation; (ii) has all requisite corporate power, and has all material
governmental licenses, authorizations, consents and approvals necessary to own
its assets and carry on its business as now being or as proposed to be
conducted; and (iii) is qualified to do business in all

                                       34
<PAGE>
 
jurisdictions in which the nature of the business conducted by it makes such
qualification necessary and where failure so to qualify would have a Material
Adverse Effect.

   Section 7.02  Financial Condition.  The audited balance sheet of the Company
as at December 31, 1994 and the related statements of operations, cash flows and
changes in partners' capital and common shareholders' equity of the Company and
its predecessor for each of the three years in the period ended on said date,
with the opinion thereon of Deloitte & Touche LLP heretofore furnished to each
of the Lenders, are complete and correct and fairly present the financial
condition of the Company as at said date and the results of operations and cash
flows of the Company and its predecessor for the stated periods then ended, all
in accordance with GAAP. Neither the Company nor any Subsidiary has on the
Closing Date any material Debt, contingent liabilities, liabilities for taxes,
unusual forward or long-term commitments or unrealized or anticipated losses
from any unfavorable commitments, except as referred to or reflected or provided
for in the Financial Statements or in Schedule 7.02. Since December 31, 1994 to
the Closing Date, there has been no change or event having a Material Adverse
Effect.  Since the date of the Financial Statements to the Closing Date, neither
the business nor the Properties of the Company or any Subsidiary have been
materially and adversely affected as a result of any fire, explosion,
earthquake, flood, drought, windstorm, accident, strike or other labor
disturbance, embargo, requisition or taking of Property or cancellation of
contracts, permits or concessions by any Governmental Authority, riot,
activities of armed forces or acts of God or of any public enemy.

   Section 7.03  Litigation.  As of the Closing Date, except as disclosed to the
Lenders in Schedule 7.03, there is no litigation, legal, administrative or
arbitral proceeding, investigation or other action of any nature pending or, to
the knowledge of the Company threatened against or affecting the Company or any
Subsidiary which involves the possibility of any judgment or liability against
the Company or any Subsidiary not fully covered by insurance (except for normal
deductibles), and which would have a Material Adverse Effect.

   Section 7.04  No Breach.  Neither the execution and delivery of the Loan
Documents, nor compliance with the terms and provisions hereof will conflict
with or result in a breach of, or require any consent which has not been
obtained as of the Closing Date under, the respective charter or by-laws of the
Company or any Subsidiary, or any Governmental Requirement or any agreement or
instrument for borrowed money to which the Company or any Subsidiary is a party
or by which it is bound or to which it or its Properties are subject, or
constitute a default under any such agreement or instrument, or result in the
creation or imposition of any Lien upon any of the revenues or assets of the
Company or any Subsidiary pursuant to the terms of any such agreement or
instrument other than the Liens created by the Loan Documents.

   Section 7.05  Authority.  The Company and each Subsidiary have all necessary
corporate power and authority to execute, deliver and perform its obligations
under the Loan Documents to which it is a party; and the execution, delivery and
performance by the

                                       35
<PAGE>
 
Company and each Subsidiary of the Loan Documents to which it is a party, have
been duly authorized by all necessary corporate action on its part; and the Loan
Documents constitute the legal, valid and binding obligations of the Company and
each Subsidiary, enforceable in accordance with their terms, except to the
extent that enforcement may be limited by bankruptcy, insolvency or similar laws
affecting the enforcement of creditor's rights generally.

   Section 7.06  Approvals.  No authorizations, approvals or consents of, and no
filings or registrations with, any Governmental Authority are necessary for the
execution, delivery or performance by the Company or any Subsidiary of the Loan
Documents or for the validity or enforceability thereof.

   Section 7.07  Use of Loans.  The proceeds of the Loans shall be used for
acquisition funding, working capital or general corporate purposes of the
Company.  Neither the Company nor any Designated Subsidiary is engaged
principally, or as one of its important activities, in the business of extending
credit for the purpose, whether immediate, incidental or ultimate, of buying or
carrying margin stock (within the meaning of Regulation G, U or X of the Board
of Governors of the Federal Reserve System).  Following application of the
proceeds of each Borrowing, not more than 25 percent of the value of the assets
(either of each Obligor only or of the Company and its Subsidiaries on a
consolidated basis), which are subject to any arrangement with the
Administrative Agent or any Lender (herein or otherwise) whereby the Company's
or any Subsidiary's right or ability to sell, pledge or otherwise dispose of
assets is in any way restricted, will be margin stock (within the meaning of
Regulation U of the Board of Governors of the Federal Reserve System).

   Section 7.08  ERISA.  As of the Closing Date, except as would not have a
Material Adverse Effect:

   (a)  The Company, the Subsidiaries and each ERISA Affiliate have complied in
all material respects with ERISA and, where applicable, the Code regarding each
Plan.

   (b) No act, omission or transaction has occurred which could result in
imposition on the Company, any Subsidiary or any ERISA Affiliate (whether
directly or indirectly) of (i) either a material civil penalty assessed pursuant
to subsections (c), (i) or (l) of section 502 of ERISA or a tax imposed pursuant
to Chapter 43 of Subtitle D of the Code or (ii) breach of fiduciary duty
liability damages under section 409 of ERISA.

   (c) No liability to the PBGC (other than for the payment of current premiums
which are not past due) by the Company, any Subsidiary or any ERISA Affiliate
has been or is expected by the Company, any Subsidiary or any ERISA Affiliate to
be incurred with respect to any Plan.  No ERISA Event with respect to any Plan
has occurred which could result in a liability of the Company, any Subsidiary or
any ERISA Affiliate.

                                       36
<PAGE>
 
   (d) Full payment when due has been made of all amounts which the Company, the
Subsidiaries or any ERISA Affiliate is required under the terms of each Plan or
applicable law to have paid as contributions to such Plan as of the date hereof,
and no accumulated funding deficiency (as defined in section 302 of ERISA and
section 412 of the Code), whether or not waived, exists with respect to any
Benefit Plan.

   (e) The actuarial present value of the benefit liabilities under each Benefit
Plan which is subject to Title IV of ERISA does not, as of the end of the
Company's most recently ended fiscal year, exceed the current value of the
assets (computed on a plan termination basis in accordance with Title IV of
ERISA) of such Benefit Plan allocable to such benefit liabilities.  The term
"actuarial present value of the benefit liabilities" shall have the meaning
specified in section 4041 of ERISA.

   (f) Neither the Company, the Subsidiaries nor any ERISA Affiliate has
received any notification (or has knowledge of any reason to expect) that any
Multiemployer Plan is in reorganization, is insolvent or has been terminated,
within the meaning of Title IV of ERISA.

   (g) Neither the Company, the Subsidiaries nor any ERISA Affiliate is required
to provide security under section 401(a)(29) of the Code due to a Plan amendment
that results in an increase in current liability for the Plan.

   Section 7.09  Taxes.  Except as set out in Schedule 7.09, each of the Company
and its Subsidiaries has filed all United States Federal income tax returns and
all other tax returns which are required to be filed by them and has paid all
material taxes due pursuant to such returns or pursuant to any assessment
received by the Company or any Subsidiary except for any such tax, assessment,
charge or levy the payment of which is being contested in good faith and by
proper proceedings and against which adequate reserves are being maintained.
The charges, accruals and reserves on the books of the Company and its
Subsidiaries in respect of taxes and other governmental charges are, in the
opinion of the Company, adequate. No tax lien has been filed and, to the
knowledge of the Company, no claim is being asserted with respect to any such
tax, fee or other charge.

   Section 7.10  Titles, etc.  To the best of the Company's knowledge:

   (a) Except as set out in Schedule 7.10, each of the Company and the
Designated Subsidiaries and Subsidiary Guarantors has good and defensible title
to its material (individually or in the aggregate) Properties in all material
respects, free and clear of all Liens except Liens permitted by Section 9.02.

   (b) All leases and agreements necessary for the conduct of the business of
the Company and the Designated Subsidiaries and Subsidiary Guarantors are valid
and subsisting, in full force and effect and there exists no default or event or
circumstance which with the giving of notice or the passage of time or both
would

                                       37
<PAGE>
 
give rise to a default under any such lease or leases, which would affect in any
material respect the conduct of the business of the Company and the Designated
Subsidiaries and Subsidiary Guarantors.

   (c) The rights, properties and other assets presently owned, leased or
licensed by the Company and the Designated Subsidiaries and Subsidiary
Guarantors including, without limitation, all easements and rights of way,

and the Designated Subsidiaries and Subsidiary Guarantors to conduct their
business in all material respects in the same manner as its business has been
conducted prior to the Closing Date.

furnished to the Agents or the Lenders by or on behalf of the Company or any
Subsidiary in connection with the negotiation and administration of this
Agreement contains any material misstatement of fact or omits to state a
material fact necessary in order to make the statements contained therein not
misleading.

which the

<PAGE>
 
Company or any Subsidiary is a party or by which the Company or any Subsidiary

agents, accountants, attorneys and experts and shall not be responsible for the
negligence or misconduct of any such agents, accountants, attorneys or experts
selected by it in good faith or any action taken or omitted to be taken in good
faith by it in accordance with the advice of such agents, accountants, attorneys
or experts.  Each Agent may deem and treat the payee of any Note as the holder
thereof for all purposes hereof unless and until a written notice of the
assignment or transfer thereof permitted hereunder shall have been filed with
the Administrative Agent.

Loans made by it, each Agent (and any successor acting as an Agent) in its
capacity as a Lender hereunder shall have the same rights and powers hereunder
as any other Lender and may exercise the same as though it were not acting as an
Agent, and the term "Lender" or "Lenders" shall, unless the context otherwise
indicates, include each Agent in its individual capacity.  Each Agent (and any
successor acting as an Agent) and its Affiliates may (without having to account
therefor to any Lender) accept deposits from, lend money to and generally engage
in any kind of banking, trust or other business with the Company (any and of its
Affiliates) as if it were not acting as an Agent, and each Agent and its
Affiliates may accept fees and other consideration from the Company for services

Company (or any of its Affiliates) which may come into the possession of any
Agent, or any of its Affiliates.

   Section 11.07  Action by Agent.  Except for action or other matters expressly
required of the Administrative Agent or Auction Agent hereunder, the
Administrative Agent or Auction Agent shall in all cases be fully justified in
failing or refusing to act hereunder unless it shall (i) receive written
instructions from the Majority Lenders (or if this Agreement requires, all of
the Lenders) specifying the action to be taken, and (ii) be indemnified to its
satisfaction by the Lenders against any and all liability and expenses which may
be incurred by it by reason of taking or continuing to take any such action
except for gross negligence or wilful misconduct.  The instructions of the
Majority Lenders (or if this Agreement requires, all of the Lenders) and any
action taken or failure to act pursuant thereto by the Administrative Agent or
Auction Agent shall be binding on all of the Lenders.  If a Default has occurred
and is continuing, the Administrative Agent or Auction Agent shall take such
action with respect to such Default as shall be directed by the

                                       54
<PAGE>
 
Majority Lenders (or if this Agreement requires, all of the Lenders) in the
written instructions (with indemnities) described in this Section 11.07,
provided that, unless and until the Administrative Agent or Auction Agent shall
have received such directions, the Administrative Agent or Auction Agent may
(but shall not be obligated to) take such action, or refrain from taking such
action, with respect to such Default as it shall deem advisable in the best
interests of the Lenders.  In no event, however, shall any Agent be required to
take any action which exposes such Agent to personal liability or which is
contrary to this Agreement and the other Loan Documents or applicable law.

   Section 11.08  Resignation or Removal of the Agents.  Subject to the
appointment and acceptance of a successor as provided below, the Administrative
Agent or Auction Agent may resign at any time by giving notice thereof to the
Lenders and the Company, and the Administrative Agent or Auction Agent may be
removed at any time with or without cause by the Majority Lenders.  Upon any
such resignation or removal, the Majority Lenders shall have the right to
appoint a successor Administrative Agent or Auction Agent as the case may be. If
no successor Administrative Agent or Auction Agent shall have been so appointed
by the Majority Lenders and shall have accepted such appointment within thirty
(30) days after the retiring Administrative Agent's or Auction Agent's giving of
notice of resignation or the Majority Lenders' removal of the retiring
Administrative Agent or Auction Agent, then the retiring Administrative Agent or
Auction Agent, as the case may be, may, on behalf of the Lenders, appoint a
respective successor Administrative Agent or Auction Agent.  Upon the acceptance
of such appointment hereunder by a successor Administrative Agent or Auction
Agent, such successor Administrative Agent or Auction Agent shall thereupon
succeed to and become vested with all the rights, powers, privileges and duties
of the retiring Administrative Agent or Auction Agent, as the case may be, and
the retiring Administrative Agent or Auction Agent shall be discharged from its
duties and obligations hereunder.  After any retiring Administrative Agent's or
Auction Agent's resignation or removal hereunder as Administrative Agent or
Auction Agent, the provisions of this Article XI and Section 12.03 shall
continue in effect for its benefit in respect of any actions taken or omitted to
be taken by it while it was acting as the Administrative Agent or Auction Agent.

                                  ARTICLE XII

                                 MISCELLANEOUS

   Section 12.01  Waiver.  No failure on the part of any Agent or any Lender to
exercise and no delay in exercising, and no course of dealing with respect to,
any right, power or privilege under any of the Loan Documents shall operate as a
waiver thereof, nor shall any single or partial exercise of any right, power or
privilege under any of the Loan Documents preclude any other or further exercise
thereof or the exercise of any other right, power or privilege. The remedies
provided herein are cumulative and not exclusive of any remedies provided by
law.

REQUIREMENT, (V) ANY INACCURACY OF ANY REPRESENTATION OR ANY BREACH OF ANY
WARRANTY OF THE COMPANY SET FORTH IN ANY OF THE LOAN DOCUMENTS, (VI) ANY
ASSERTION THAT THE LENDERS WERE NOT ENTITLED TO RECEIVE THE PROCEEDS RECEIVED
PURSUANT TO THE LOAN DOCUMENTS OR (VII) ANY OTHER ASPECT OF THE LOAN DOCUMENTS,

BUT EXCLUDING ALL INDEMNITY MATTERS ARISING SOLELY BY REASON OF CLAIMS BETWEEN
THE LENDERS OR ANY LENDER AND ANY AGENT OR A LENDER'S SHAREHOLDERS AGAINST ANY
AGENT OR LENDER OR BY REASON OF THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT ON
THE PART OF SUCH INDEMNIFIED PARTY; AND

   (c) TO INDEMNIFY AND HOLD HARMLESS FROM TIME TO TIME EACH INDEMNIFIED PARTY

ADMINISTRATIVE ORDERS OR PROCEEDINGS, DAMAGES AND LIABILITIES TO WHICH ANY SUCH
PERSON MAY BECOME SUBJECT (I) UNDER ANY ENVIRONMENTAL LAW APPLICABLE TO THE

FORECLOSURE, AS MORTGAGEE-IN-POSSESSION OR OTHERWISE).

   (d) No Indemnified Party may settle any claim to be indemnified without the
consent of the indemnitor, such consent not to be unreasonably withheld;
provided, that the indemnitor may not reasonably withhold consent to any
settlement that an Indemnified Party proposes, if the indemnitor does not have
the financial ability to pay all its obligations outstanding and asserted
against the indemnitor at

                                       57
<PAGE>
 
that time, including the maximum potential claims against the Indemnified Party
to be indemnified pursuant to this Section 12.03.

   (e)  In the case of any indemnification hereunder, the Administrative Agent
or a Lender, as appropriate shall give notice to the Company of any such claim
or demand being made against such Indemnified Party and the Company shall have
the non-exclusive right to join in the defense against any such claim or demand
provided that if the Company provides a defense, such Indemnified Party shall
bear its own cost of defense unless there is a conflict between the Company and
such Indemnified Party.

   (f)  THE FOREGOING INDEMNITIES SHALL EXTEND TO THE INDEMNIFIED PARTIES
NOTWITHSTANDING THE NEGLIGENCE OF EVERY KIND OR CHARACTER WHATSOEVER, WHETHER
ACTIVE OR PASSIVE, WHETHER AN AFFIRMATIVE ACT OR AN OMISSION, INCLUDING WITHOUT
LIMITATION, ALL TYPES OF NEGLIGENT CONDUCT IDENTIFIED IN THE RESTATEMENT
(SECOND) OF TORTS OF ONE OR MORE OF THE INDEMNIFIED PARTIES OR BY REASON OF
STRICT LIABILITY IMPOSED WITHOUT FAULT ON ANY ONE OR MORE OF THE INDEMNIFIED
PARTIES.  TO THE EXTENT THAT AN INDEMNIFIED PARTY IS FOUND TO HAVE COMMITTED AN
ACT OF GROSS NEGLIGENCE OR WILLFUL MISCONDUCT, THIS CONTRACTUAL OBLIGATION OF
INDEMNIFICATION SHALL CONTINUE BUT SHALL ONLY EXTEND TO THE PORTION OF THE CLAIM
THAT IS DEEMED TO HAVE OCCURRED BY REASON OF EVENTS OTHER THAN THE GROSS
NEGLIGENCE OR WILLFUL MISCONDUCT OF THE INDEMNIFIED PARTY.

   (g) Each Obligor's obligation under this Section 12.03 shall survive any

thirty (30) days of the receipt by the Company of notice of the amount due.

   Section 12.04  Amendments, Etc.  Any provision of this Agreement or any other
Loan Document may be amended, modified or waived with the Company's and the
Majority Lenders' prior written consent; provided that (i) no amendment,
modification or waiver which extends the maturity of the Loans, or the interest
or fee payment dates,  increases the Aggregate Commitments, forgives the
principal amount of any Indebtedness outstanding under this Agreement, reduces
the interest rate applicable to the Loans or the fees payable to the Lenders
generally, affects this Section 12.04 or Section 12.06(a) or modifies the
definition of "Majority Lenders" or any provision which by its terms requires
the consent or approval of all of the Lenders shall be effective without consent
of all Lenders; (ii) no amendment, modification or waiver which increases or
extends the Commitment of any Lender shall be effective without the consent of
such Lender; and (iii) no amendment, modification or waiver which modifies the
rights, duties or obligations of the Administrative Agent, Auction Agent or the
Syndication Agent shall be effective without the consent of such Agent.

   Section 12.05  Successors and Assigns.  This Agreement shall be binding upon
and inure to the benefit of the parties hereto and their respective successors
and permitted assigns.

   Section 12.06  Assignments and Participations.

   (a) No Obligor may assign its rights or obligations hereunder or under the
Notes without the prior consent of all of the Lenders and the Agents.

   (b) Any Lender may, upon the written consent of the Company (which consent
shall not be unreasonably withheld) assign to one or more assignees all or a
portion of its rights and obligations under this Agreement and the other Loan
Documents pursuant to an Assignment Agreement substantially in the form of
Exhibit K (an "Assignment") provided, however, that (i) any such assignment
shall be in the amount of at least $10,000,000 or such lesser amount to which
the Company has consented and (ii) the assignor or assignee shall pay to the
Administrative Agent a processing and recordation fee of $2500 for each
assignment.  Any such assignment will become effective upon the execution and
delivery to the Administrative Agent of the Assignment and the written consent
of the Company.  Promptly after receipt of an executed Assignment, the
Administrative Agent shall send to the Company a copy of such executed
Assignment.  Upon receipt of such executed Assignment, the Company, will, at its
own expense, execute and deliver new Notes to the assignor and/or assignee, as
appropriate, in accordance with their respective interests as they appear.  Upon
the effectiveness of any assignment pursuant to this Section 12.06(b), the
assignee will become a "Lender," if not already a "Lender," for all purposes of
this Agreement and the other Loan Documents.  The assignor shall be relieved of
its obligations hereunder to the extent of such assignment (and if the assigning
Lender no longer holds any rights or obligations under this Agreement, such
assigning Lender shall cease to be a "Lender" hereunder except that its rights
under Sections 4.06, 5.01, 5.05 and 12.03 shall not be affected).  The
Administrative Agent will prepare on the last Business Day of each month during
which an assignment has become effective pursuant to this Section 12.06(b), a
new Annex 1 giving effect to all such assignments effected during such month,
and will promptly provide the same to the Company and each of the Lenders.

   (c) Each Lender may transfer, grant or assign participations in all or any
part of such Lender's interests, rights and obligations hereunder pursuant to
this Section 12.06(c) to any Person, provided that: (i) such Lender shall remain
a "Lender" for all purposes of this Agreement and the transferee of such
participation shall not constitute a "Lender" hereunder; and (ii) no participant
under any such participation shall have rights to approve any amendment to or
waiver of any of the Loan Documents except to the extent such amendment or
waiver would (x) extend the Revolving Credit Termination Date, (y) reduce the
interest rate (other than as a result of waiving the applicability of any post-
default increases in interest rates) or fees applicable to any of the
Commitments or Loans in which such participant is

                                       59
<PAGE>
 
participating, or postpone the payment of any thereof, or (z) release all or
substantially all of the collateral (except as expressly provided in the other
Loan Documents) supporting any of the Commitments or Loans in which such
participant is participating.  In the case of any such participation, the
participant shall not have any rights under this Agreement or any of the other
Loan Documents (the participant's rights against the granting Lender in respect
of such participation to be those set forth in the agreement with such Lender
creating such participation), and all amounts payable by the Company hereunder
shall be determined as if such Lender had not sold such participation, provided
that such participant shall be entitled to receive additional amounts under
Article V on the same basis as if it were a Lender and be indemnified under
Section 12.03 as if it were a Lender.  In addition, each agreement creating any
participation must include an agreement by the participant to be bound by the
provisions of Section 12.15.

   (d) The Lenders may furnish any information concerning the Company in the
possession of the Lenders from time to time to assignees and participants
(including prospective assignees and participants); provided such Persons agree
in writing to be bound by the provisions of Section 12.15.

   (e) Notwithstanding anything in this Section 12.06 to the contrary, any
Lender may assign and pledge its Note to any Federal Reserve Bank or the United
States Treasury as collateral security pursuant to Regulation A of the Board of
Governors of the Federal Reserve System and any operating circular issued by
such Federal Reserve System and/or such Federal Reserve Bank.  No such
assignment and/or pledge shall release the assigning and/or pledging Lender from
its obligations hereunder.

   (f) Notwithstanding any other provisions of this Section 12.06, no transfer
or assignment of the interests or obligations of any Lender or any grant of
participations therein shall be permitted if such transfer, assignment or grant
would require the Company to file a registration statement with the SEC or to
qualify the Loans under the "Blue Sky" laws of any state.

   Section 12.07  Invalidity.  In the event that any one or more of the
provisions contained in any of the Loan Documents shall, for any reason, be held
invalid, illegal or unenforceable in any respect, such invalidity, illegality or
unenforceability shall not affect any other provision of the Notes, this
Agreement or any other Loan Document.

   Section 12.08  Counterparts.  This Agreement may be executed in any number of
counterparts, all of which taken together shall constitute one and the same
instrument and any of the parties hereto may execute this Agreement by signing
any such counterpart.

   Section 12.09  References.  The words "herein," "hereof," "hereunder" and
other words of similar import when used in this Agreement refer to this
Agreement as a whole, and not to any particular article, section or subsection.
Any reference herein to a

unless otherwise stated herein.  Any reference herein to an exhibit or schedule
shall be deemed to refer to the applicable exhibit or schedule attached hereto
unless otherwise stated herein.

   Section 12.10  Survival. The obligations of the parties under Section 4.06,
Article V, and Sections 11.05 and 12.03 shall survive the repayment of the Loans
and the termination of the Commitments.  To the extent that any payments on the
Indebtedness or proceeds of any collateral are subsequently invalidated,
declared to be fraudulent or preferential, set aside or required to be repaid to
a trustee, debtor in possession, receiver or other Person under any bankruptcy
law, common law or equitable cause, then to such extent, the Indebtedness so
satisfied shall be revived and continue as if such payment or proceeds had not
been received and the Administrative Agent's and the Lenders' Liens, security
interests, rights, powers and remedies under this Agreement and each other Loan
Document shall continue in full force and effect.  In such event, each Loan
Document shall be automatically reinstated and the Company shall take such
action as may be reasonably requested by the Administrative Agent and the
Lenders to effect such reinstatement.

   Section 12.11  Captions.  Captions and section headings appearing herein and
the table of contents hereto are included solely for convenience of reference

Agreement.

   Section 12.12  NO ORAL AGREEMENTS.  THE LOAN DOCUMENTS EMBODY THE ENTIRE
AGREEMENT AND UNDERSTANDING BETWEEN THE PARTIES AND SUPERSEDE ALL OTHER
AGREEMENTS AND UNDERSTANDINGS BETWEEN SUCH PARTIES RELATING TO THE SUBJECT
MATTER HEREOF AND THEREOF.  THE LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT
BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR,
CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.  THERE ARE NO
UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

   Section 12.13  GOVERNING LAW; SUBMISSION TO JURISDICTION.

   (A) THIS AGREEMENT AND THE NOTES SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF TEXAS EXCEPT TO THE EXTENT THAT UNITED
STATES FEDERAL LAW PERMITS ANY LENDER TO CHARGE INTEREST AT THE RATE ALLOWED BY
THE LAWS OF THE STATE WHERE SUCH LENDER IS LOCATED.  TEX. REV. CIV. STAT. ANN.
ART. 5069, CH. 15 (WHICH REGULATES CERTAIN REVOLVING CREDIT LOAN ACCOUNTS AND
REVOLVING TRI-PARTY ACCOUNTS) SHALL NOT APPLY TO THIS AGREEMENT OR THE NOTES.

   (B) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THE LOAN DOCUMENTS MAY BE
BROUGHT IN THE COURTS OF THE STATE OF TEXAS OR OF THE UNITED STATES OF AMERICA
FOR THE SOUTHERN DISTRICT OF TEXAS, AND, BY EXECUTION AND DELIVERY OF THIS
AGREEMENT, THE COMPANY HEREBY ACCEPTS FOR ITSELF AND (TO THE EXTENT PERMITTED BY
LAW) IN RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, THE JURISDICTION
OF THE AFORESAID COURTS.

                                       61
<PAGE>
 
THE COMPANY HEREBY IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING, WITHOUT
LIMITATION, ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF
FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY
SUCH ACTION OR PROCEEDING IN SUCH RESPECTIVE JURISDICTIONS.  THIS SUBMISSION TO
JURISDICTION IS NON-EXCLUSIVE AND DOES NOT PRECLUDE THE ADMINISTRATIVE AGENT OR
ANY LENDER FROM OBTAINING JURISDICTION OVER THE COMPANY IN ANY COURT OTHERWISE
HAVING JURISDICTION.

   (C)  NOTHING HEREIN SHALL AFFECT THE RIGHT OF THE ADMINISTRATIVE AGENT OR ANY
LENDER OR ANY HOLDER OF A NOTE TO SERVE PROCESS IN ANY MANNER PERMITTED BY LAW
OR TO COMMENCE LEGAL PROCEEDINGS OR OTHERWISE PROCEED AGAINST THE COMPANY IN ANY
OTHER JURISDICTION.

   (D) EACH OF THE COMPANY AND EACH LENDER HEREBY (I) IRREVOCABLY AND
UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, TRIAL BY JURY IN
ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER LOAN
DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN; (II) IRREVOCABLY WAIVES, TO THE
MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER
IN ANY SUCH LITIGATION ANY SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL
DAMAGES, OR DAMAGES OTHER THAN, OR IN ADDITION TO, ACTUAL DAMAGES; (III)
CERTIFIES THAT NO PARTY HERETO NOR ANY REPRESENTATIVE OR AGENT OF COUNSEL FOR
ANY PARTY HERETO HAS REPRESENTED, EXPRESSLY OR OTHERWISE, OR IMPLIED THAT SUCH
PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING
WAIVERS, AND (IV) ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO ENTER INTO THIS
AGREEMENT, THE OTHER LOAN DOCUMENTS AND THE TRANSACTIONS CONTEMPLATED HEREBY AND
THEREBY BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS CONTAINED
IN THIS SECTION 12.13.

   Section 12.14  Interest.  It is the intention of the parties hereto that each
Lender shall conform strictly to usury laws applicable to it. Accordingly, if
the transactions contemplated hereby would be usurious as to any Lender under
laws applicable to it (including the laws of the United States of America and
the State of Texas or any other jurisdiction whose laws may be mandatorily
applicable to such Lender notwithstanding the other provisions of this
Agreement), then, in that event, notwithstanding anything to the contrary in any
of the Loan Documents or any agreement entered into in connection with or as
security for the Notes, it is agreed as follows:  (i) the aggregate of all
consideration which constitutes interest under law applicable to any Lender that
is contracted for, taken, reserved, charged or received by such Lender under any
of the Loan Documents or agreements or otherwise in connection with the Notes
shall under no circumstances exceed the maximum amount allowed by such
applicable law, and any excess shall be cancelled automatically and if
theretofore paid shall be credited by such Lender on the principal amount of the
Indebtedness (or, to the extent that the principal amount of the Indebtedness
shall have been or would thereby be paid in full, refunded by such Lender to the
Company);

                                       62
<PAGE>
 
and (ii) in the event that the maturity of the Notes is accelerated by reason of
an election of the holder thereof resulting from any Event of Default or
otherwise, or in the event of any required or permitted prepayment, then such
consideration that constitutes interest under law applicable to any Lender may
never include more than the maximum amount allowed by such applicable law, and
excess interest, if any, provided for in this Agreement or otherwise shall be
cancelled automatically by such Lender as of the date of such acceleration or
prepayment and, if theretofore paid, shall be credited by such Lender on the
principal amount of the Indebtedness (or, to the extent that the principal
amount of the Indebtedness shall have been or would thereby be paid in full,
refunded by such Lender to the Company).  All sums paid or agreed to be paid to
any Lender for the use, forbearance or detention of sums due hereunder shall, to
the extent permitted by law applicable to such Lender, be amortized, prorated,
allocated and spread throughout the full term of the Loans evidenced by the
Notes until payment in full so that the rate or amount of interest on account of
any Loans hereunder does not exceed the maximum amount allowed by such
applicable law.  If at any time and from time to time (i) the amount of interest
payable to any Lender on any date shall be computed at the Highest Lawful Rate
applicable to such Lender pursuant to this Section 12.14 and (ii) in respect of
any subsequent interest computation period the amount of interest otherwise
payable to such Lender would be less than the amount of interest payable to such
Lender computed at the Highest Lawful Rate applicable to such Lender, then the
amount of interest payable to such Lender in respect of such subsequent interest
computation period shall continue to be computed at the Highest Lawful Rate
applicable to such Lender until the total amount of interest payable to such
Lender shall equal the total amount of interest which would have been payable to
such Lender if the total amount of interest had been computed without giving
effect to this Section 12.14.  To the extent that Article 5069-1.04 of the Texas
Revised Civil Statutes is relevant for the purpose of determining the Highest
Lawful Rate, such Lender elects to determine the applicable rate ceiling under
such Article by the indicated weekly rate ceiling from time to time in effect.

   Section 12.15  Confidentiality.   In the event that the Company provides to
the Agents or the Lenders written confidential information belonging to the
Company, if the Company shall denominate such information in writing as
"confidential", the Agents and the Lenders shall thereafter maintain such
information in confidence in accordance with the standards of care and diligence
that each utilizes in maintaining its own confidential information.  This
obligation of confidence shall not apply to such portions of the information
which (i) are in the public domain, (ii) hereafter become part of the public
domain without the Agents or the Lenders breaching their obligation of
confidence to the Company, (iii) are previously known by the Agents or the
Lenders from some source other than the Company, (iv) are hereafter developed by
the Agents or the Lenders without using the Company's information, (v) are
hereafter obtained by or available to the Agents or the Lenders from a third
party who owes no obligation of confidence to the Company with respect to such
information or through any other means other than through disclosure by the
Company, (vi) are disclosed with the Company's consent, (vii) must be disclosed
either pursuant to any Governmental Requirement or to Persons regulating the
activities of the Agents or the Lenders, or (viii) as may be required by law or
regulation or order of any
                                       63
<PAGE>
 
Governmental Authority in any judicial, arbitration or governmental proceeding.
Further, an Agent or a Lender may disclose any such information to any other
Lender, any Affiliate of such Agent or Lender, any independent petroleum
engineers or consultants, any independent certified public accountants, any
legal counsel employed by such Person in connection with this Agreement or any
other Loan Document, including without limitation, the enforcement or exercise
of all rights and remedies thereunder, or any assignee or participant (including
prospective assignees and participants) in the Loans; provided, however, that
such Agent or Lender imposes on the Person to whom such information is disclosed
the same obligation to maintain the confidentiality of such information as is
imposed upon it hereunder.  Notwithstanding anything to the contrary provided
herein, this obligation of confidence shall cease three (3) years from the date
the information was furnished, unless the Company requests in writing at least
thirty (30) days prior to the expiration of such three year period, to maintain
the confidentiality of such information for an additional three year period. The
Company waives any and all other rights it may have to confidentiality as
against the Agents and the Lenders arising by contract, agreement, statute or
law except as expressly stated in this Section 12.15.

   Section 12.16  Effectiveness.  This Agreement shall not be effective until
executed by all parties hereto and delivered to and accepted by the
Administrative Agent, and the other conditions listed in the definition of
"Effective Date" have occurred.

   Section 12.17  EXCULPATION PROVISIONS.  EACH OF THE PARTIES HERETO
SPECIFICALLY AGREES THAT IT HAS A DUTY TO READ THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS AND AGREES THAT IT IS CHARGED WITH NOTICE AND KNOWLEDGE OF THE TERMS
OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; THAT IT HAS IN FACT READ THIS

IV.   BONUS POOL
      ----------
 
      Awards shall be made at the discretion of the Company from a Bonus Pool,
the maximum amount of which shall be determined by the NPV of exploratory and
exploitation reserve additions as follows:

         $XXXXX per million dollars of incremental NPV which results from
         reserve additions, technology applications, or expense reduction.
 
      The actual amount of the Bonus Pool will be equal to or less than the
maximum set above, with the amount awarded based upon management assessment of
relevant factors in evaluating overall team performance.  Among the factors
which will be considered are the following:

      1.   Value added - did the team make a material contribution in an area
           such as enticing a submittal, trading the deal, originating a
           geologic concept, putting a land deal together, etc. which
           represented an extraordinary contribution to the viability of the
           project?

      2.   Originality - was the project the result of a new concept or an
           extension of a proven concept?

      3.   Technical difficulty - did the project involve a unique application
           of technology or leverage technical expertise from prior experience?

V.    TYPES OF AWARDS
      ---------------

      A.  Team Awards
          -----------

          A portion of each Bonus Pool will be made available for awards to
          project team members responsible for the initiation of a project which
          adds economic reserves and thereby enhances the value of the Company
          as measured by NPV analysis .

          Eighty shares, as defined in Section VI, of a given Bonus Pool arising
          out of an NPV addition as previously defined will be allocated for
          individual awards to applicable team members as described in Section
          VI.,A.

          (1)  Onshore
               -------

               a.  Primary Awards - will be based on the expected NPV of the
                   well or wells in the calendar year in which first production
                   occurs.

               b.  Subsequent Awards - subsequent NPV will be established at the
                   end of the second calendar year after the year of the Primary
                   Award evaluation and not later than five years after the year
                   of the Primary Award evaluation. Awards after the Primary
                   Award will be based on NPV enhancement for the project beyond
                   that which was the basis for prior awards.

          (2)  Offshore/International
               ----------------------

               a.  Primary Awards - will be evaluated at the end of the calendar
                   year in which the DOCD is filed with the MMS or international
                   project development approval is given and will be based on
                   the projected NPV proven at that time.

               b.  Subsequent Awards - will be based on the expected incremental
                   NPV of the "project" beyond that serving as the basis of the
                   Primary Award. These will be awarded at the end of the
                   calendar year in which (a) project startup occurs (initial
                   production); and (b) two years after project startup.

B.    District Awards
      ---------------

      A portion of each Bonus Pool awarded within a district will be made
      available at the discretion of the Company for awards to eligible district
      employees for contribution to the achievement of district operating goals

      Awards to be granted, all district operating goals and objectives must
      have been achieved. District Awards will be funded through the

                                       4
<PAGE>
 
      allocation of a portion of each Bonus Pool generated through an NPV
      increase as described in Section IV. Any such funding for District Awards
      will either be granted in accordance with this provision or will expire on
      an annual basis. No such pool will carry over from year to year with
      respect to District Awards.

      Twenty shares, as defined in Section VI, of any Bonus Pool created during
      a given budget year will be eligible for allocation for discretionary
      awards to eligible district employees as described in Section VI.,B.

VI.   BONUS AWARDS
      ------------

      Individual bonus awards shall be based upon the number of bonus "shares"
which are awarded to each Participant.  Each Bonus Pool shall be divided into
100 equal shares, and shall be allocated for either Team or District Awards.
The value of each share shall be the total value of that Bonus Pool divided by
100.

      A.  Team Bonus Share Distribution
          -----------------------------

          The final team bonus share distribution will be determined by the
          President, Enserch Exploration, Inc. in consultation with the Regional
          Director or Vice President, Production. Team members, including the
          Team Leader, who are Participants in a Bonus Pool will be provided a
          confidential envelope addressed to the Controller, ENSERCH
          Corporation. Each team member will individually suggest a bonus share
          distribution for the pool. These suggestions will be tabulated and
          provided anonymously to the President, Enserch Exploration, Inc. who
          will consider them along with the recommendation of the Regional
          Director or Vice President, Production in determining the actual bonus
          share distribution.

      B.  District Bonus Share Distribution
          ---------------------------------

          The final district bonus share distribution will be determined by the
          President, Enserch Exploration, Inc. in consultation with the Regional
          Director or Vice President, Production.

          District bonus awards shall be totally discretionary. The Regional
          Director and VP, Production may make recommendations as to both
          participants and individual awards based upon individual contribution
          to the achievement of district operating goals and objectives. They
          may solicit input as appropriate from district operating personnel.
          These recommendations will be submitted to the President, Enserch
          Exploration, Inc. who will determine the actual bonus share
          distribution.

      C.  Credited Awards
          ---------------

          An award shall be "credited" at the time a determination is made as to
          the Participants, the Bonus Pool, and the bonus share distribution,
          upon authorization by the President, Enserch Exploration, Inc. Rights
          to payments are "earned" at the time the payment is made.

                                       5
<PAGE>
 
VII.  PAYMENTS
      --------

      Each award shall be paid in equal annual payments over a three-year period
                                  ----------------------------------------------
subject to the following limitations:

      A.  The first payment due a Participant under an award will be made prior
          to April 1 of the calendar year following the year of the Primary
          Award or any Subsequent Award. Equal annual payments due will be made
          by April 1 of subsequent calendar years.

      B.  Annual payments under the Plan will be limited to a maximum of 100
          percent of a Participant's annualized base salary (exclusive of
          employee benefits and any other compensation). For example, a
          Participant earning an annual salary of $50,000 would not receive an
          annual award payment in excess of $50,000. If any Participant earns
          awards greater than his or her annualized base salary in an award
          year, or has cumulative awards which if paid would result in an amount
          greater than the annualized base salary, that portion of the award or
          awards shall be carried forward into succeeding calendar years such
          that in no calendar year will cumulative awards exceed 100 percent of
          the Participant's annualized base salary. Any such award carried
          forward into a succeeding calendar year will be treated the same as a
          subsequent award with respect to its being "credited."

      C.  To be eligible for receipt of any payment, a Participant must continue
          to be employed by the Corporation at the time each payment is to be
          paid unless the Participant's employment terminates by reason of
          retirement, death, or disability as described below:

          Effect of Termination of Employment, Retirement or Death
          --------------------------------------------------------

          1.  Participants who voluntarily terminate their employment, excluding
              normal retirement, or who are terminated by the Corporation for
              cause will not be eligible to receive any bonus payments under the
              terms of this Plan.
 
          2.  Any Participant who takes normal retirement at age 65 or above in
              accordance with the Corporation's approved retirement plan,
              becomes disabled and receives disability benefits in accordance
              with the Corporation's long-term disability plan, or is terminated
              at the Corporation's motion not for cause shall be eligible to
              receive all bonus awards credited under this Plan during his or
              her active employment. Any such credited but unpaid awards will be
              pooled and paid out in three (3) equal installments over the three
              (3) years following such retirement, disability, or termination.

          3.  Any Participant who voluntarily retires after age 60 but prior to
              age 65 or above shall be eligible to petition

                                       6
<PAGE>
 
              for payment of any credited but unpaid awards with the decision
              regarding such payment to be at the discretion of the President,
              Enserch Exploration, Inc.

          4.  In the event of a Participant's death, all bonus awards which have
              been credited to such Participant prior to the date of death but
              remain unpaid and which would otherwise have been received will be
              paid to the designated beneficiary, or if no beneficiary is
              designated, to the employee's estate, in one lump sum as soon as
              is practicable but no later than six months following the death of
              the employee.

          5.  In the event that ENSERCH Corporation shall, pursuant to action by
              its Board, at any time propose to merge into, consolidate with,
              sell, or otherwise transfer all or substantially all of the assets
              of Enserch Exploration, Inc., to another non-related or non-
              affiliated corporation, all bonus awards which have been credited
              but remain unpaid shall be immediately paid to the Participant,
              and the Participant shall not be required to be employed by the
              Corporation in order to receive payment.

VIII. PROVEN RESERVES
      ---------------

      Any awards shall be based on the discounted NPV of the proven reserves, as
determined and defined by DeGolyer and MacNaughton, at the time of the
evaluation, attributable to the Company's net revenue interest in each well.
The Company retains total discretion over which investments or sales it shall
make or not make which may affect this NPV.

IX.   ADMINISTRATIVE PROVISIONS
      -------------------------

      A.  Compensation Committee
          ----------------------

          The Compensation Committee of the Board of Directors of ENSERCH
          Corporation must approve any award for any Participant whose total
          annual compensation, including such bonus, would exceed $150,000.

      B.  Discretionary
          -------------

          Notwithstanding any calculation of bonus in accordance with the
          foregoing provisions, the President of ENSERCH Corporation may within
          his sole discretion alter or eliminate any bonus award developed under
          this Plan in order to achieve equity in the administration of the Plan
          within ENSERCH Corporation as a whole.

      C.  No Contract
          -----------

          Nothing in this Bonus Incentive Plan shall be deemed by implication or
          otherwise to constitute a contract of employment or otherwise to
          impose any limitation on any right of the

                                       7
<PAGE>
 
          Corporation nor any of its operating units to terminate a
          Participant's employment at any time.

      D.  Termination of Plan
          -------------------

          This Plan may be terminated by the Company at any time, either in its
          entirety or with respect to individual Participants. Plan termination
          will not prevent payment of bonuses already credited but unpaid as of
          the date of Plan termination.

      E.  Statement of Policies
          ---------------------

          If at any time an eligible Participant

          1.   is determined to be in violation of the statement of policies of
               ENSERCH Corporation, including but not limited to the Employee
               Statement of Acknowledgement, Disclosure and Commitment or,

          2.   engages in the employment, consultation, or representation of any
               corporation, partnership, individual, political subdivision, or
               any enterprise that is engaged in any action or proceeding that
               the Corporation considers adverse to or in competition with the
               interests of the Corporation,

          the Participant and his or her beneficiaries or heirs shall forfeit
          all rights to receive payments or bonus awards provided under this
          Plan regardless of whether or not such payments had been previously
          approved by the Corporation except that before any such termination
          under this section of the Participant's right to receive payments, the
          Corporation shall notify the Participant in writing of this opinion
          about the adverse situation, after which time the Participant shall
          have a period of fifteen (15) days to correct the situation to the
          satisfaction of the Corporation as to preclude benefit termination.

maintain on its books a Deferral Account for each Eligible Employee employed by
such Employer who elects to participate in this Plan. Each such Deferral Account
shall be designated by the name of the Participant for whom it is established.
The amount of any base salary and/or cash bonus from an Employer for a Plan Year
that is deferred for a Participant pursuant to Section 3.1 and/or Section 3.2
shall be credited by such Employer to such Participant's Deferral Account as of
the date such amount would otherwise have been paid to such Participant by such
Employer. An Employer shall continue maintaining a Deferral Account as long as a
positive balance remains credited to such Deferral Account.

     Section 3.4 Deferral Account Adjustments. As of each Adjustment Date, the
amount credited to a Deferral Account shall be adjusted to reflect such gain,
loss and/or expenses incurred based on the experience of the investments
selected by the Participant prior to the date prescribed by the Administrative
Committee for the investment of his or her Deferral Account and taking into
account additional deferrals credited to and distributions made from such
Deferral Account since the last Adjustment Date. The Administrative Committee
shall have sole and absolute discretion with respect to the number and type of
investment choices made available for selection by Participants pursuant to this
Section, the timing of Participant elections and the method by which adjustments
are made. The designation of investment choices by the Administrative Committee
shall be for the sole purpose of adjusting Deferral Accounts pursuant to this
Section and this provision shall not obligate the Employers to invest or set
aside any assets for the payment of benefits hereunder; provided, however, that
an Employer may invest a portion of its general assets in investments, including
investments which are the same as or similar to the investment choices
designated by the Administrative Committee and selected by Participants, but any
such investments shall remain part of the general assets of such Employer and
shall not be deemed or construed to grant a property interest of any kind to any
Participant, designated beneficiary or estate. The Administrative Committee
shall notify the Participants of the
<PAGE>
 
investment choices available and the procedures for making and changing
investment elections.

     Section 3.5 Vesting. Subject to Section 4.6, all amounts credited to a
Participant's Deferral Account shall be fully vested and nonforfeitable at all
times.


                                  ARTICLE IV.

                                   BENEFITS

     Section 4.1 Source of Benefit Payments. Benefit payments to be made with
respect to a Participant's Deferral Account maintained pursuant to the Plan will
be paid in cash and will be the obligation solely of the Employer maintaining
such Deferral Account; provided, however, that whenever a payment hereunder is
to be made by an Employer, the Company may, in its discretion, satisfy such
payment obligation on behalf of such Employer, and the Company will be obligated
to satisfy any such payment obligation in the event the Employer otherwise
liable therefor fails to pay such amount when due for any reason.

     Section 4.2 Amount of Benefit Payments. The amount payable from a
Participant's Deferral Account shall be determined based upon the amount
credited to such Deferral Account as of the Adjustment Date last preceding the
date of payment plus any deferrals credited to and less any distributions made
from such Deferral Account since such Adjustment Date. The amount of each
payment made with respect to a Deferral Account and any forfeiture amounts
applied pursuant to Section 4.6 shall be deducted from the balance credited to
such Deferral Account at the time of payment or forfeiture.

     Section 4.3  Early Termination.  Upon a Participant's termination of
employment with an Employer or Affiliated Company prior to the date which is ten
years prior to such Participant's Retirement Age for any reason other than
death, Disability or transfer to employment with another Employer or Affiliated
Company, the amount payable from such Participant's Deferral Account, as
determined in accordance with Section 4.2, shall be paid by the Employer to such
Participant in a single lump sum as soon as practicable following such
termination of employment.

     Section 4.4  Death.  Upon a Participant's termination of employment by
reason of death, the amount payable from such Participant's Deferral Account, as
determined in accordance with Section 4.2, shall be paid by the Employer to the
beneficiary or beneficiaries designated by such Participant pursuant to Section
4.7 in one of the following forms as elected by the Participant during the
Participant's initial Election Period:

          (a) a single lump sum to be paid as soon as practicable following
     the Participant's death; or

          (b) if the amount payable from a Deferral Account is $50,000 or
     more as of the date of the Participant's death, annual installments over
     the period certain selected by the Participant not to exceed 15 years
     commencing in payment as soon as practicable following the Participant's
     death with each annual installment equal
<PAGE>
 
     to the Deferral Account balance multiplied by a fraction the numerator of
     which is one and the denominator of which is the number of payments
     remaining;

provided, however, that if a beneficiary of a deceased Participant who is
entitled to installment payments hereunder encounters an unforeseeable emergency
(as determined in accordance with Section 4.8 hereof), the Administrative
Committee, in its absolute discretion, may direct the Employer to accelerate
such portion of the installment payments as the Administrative Committee shall
determine to be necessary to alleviate the severe financial hardship of the
beneficiary caused by such unforeseeable emergency.

     Section 4.5 Retirement or Disability. Upon a Participant's termination of
employment with an Employer or Affiliated Company (i) on or after the date which
is ten years prior to such Participant's Retirement Age for any reason other
than death or transfer to employment with another Employer or Affiliated Company
or (ii) on account of his or her Disability, the amount payable from such
Participant's Deferral Account, as determined in accordance with Section 4.2,
shall be paid by the Employer to such Participant (or, in the event of his or
her subsequent death, to the beneficiary or beneficiaries designated by such
Participant pursuant to Plan Section 4.7) in one of the following forms as
elected by the Participant during the Participant's initial Election Period:

          (a)  a single lump sum to be paid as soon as practicable following the
     Participant's termination of employment or, in the case of termination of
     employment on account of Disability or prior to Retirement Age and the
     Participant so elects, the Participant's Retirement Age; or

          (b) if the amount payable from a Deferral Account is $50,000 or more
     as of the date of the Participant's termination of employment, annual
     installments over the period certain selected by the Participant not to
     exceed 15 years commencing in payment as soon as practicable following the
     Participant's termination of employment or, in the case of termination of
     employment on account of Disability or prior to Retirement Age and the
     Participant so elects, the Participant's Retirement Age, with each annual
     installment equal to the Deferral Account balance multiplied by a fraction
     the numerator of which is one and the denominator of which is the number of
     payments remaining;

provided, however, that if a Participant who is entitled to a delayed lump sum
or installment payments hereunder encounters an unforeseeable emergency (as
determined in accordance with Section 4.8 hereof), the Administrative Committee,
in its absolute discretion, may direct the Employer to accelerate such portion
of the lump sum or installment payments as the Administrative Committee shall
determine to be necessary to alleviate the severe financial hardship of the
Participant caused by such unforeseeable emergency.

     Section 4.6   Option to Request Immediate Payout.  In lieu of any
other benefits or payments to be made pursuant to this Plan, each Participant
(or beneficiary in the case of a deceased Participant) shall have the right at
any time to elect a lump sum payment in an amount equal to:
<PAGE>
 
          (a) the amount payable from the Participant's Deferral Account,
     determined in accordance with Section 4.2, minus
                                                -----

          (b)  a forfeiture amount equal to 20% of (a) above, provided, however,
     that if the election is made on or within two years following the date a
     Change of Control occurs, such forfeiture amount shall be determined
     substituting 10% for 20%.

A Participant's election for an immediate payout pursuant to this Section must
be in the form of a written notice provided to the Administrative Committee.
The Administrative Committee shall notify any Employer maintaining a Deferral
Account with respect to such Participant of the election and the amount so
determined shall be paid to the Participant (or, in the case of a deceased
Participant, to the beneficiary or beneficiaries designated by such Participant
pursuant to Plan Section 4.7) by the Employers no later than fifteen days
following receipt of notice by the Administrative Committee.  Any amount
remaining credited to the Participant's Deferral Account shall be forfeited at
the time payment is made.

     Section 4.7  Designation of Beneficiaries.  Any amount payable under
this Plan on account of the death of a Participant shall be paid when otherwise
due hereunder to the beneficiary or beneficiaries designated by such
Participant.  Such designation of beneficiary or beneficiaries shall be made in
writing on a form prescribed by and filed with the Administrative Committee and
shall remain in effect until changed by such Participant by the filing of a new
beneficiary designation form with the Administrative Committee.  If a
Participant fails to so designate a beneficiary, or in the event all of the
designated beneficiaries are individuals who either predecease the Participant
or survive the Participant but die prior to receiving the full amount payable
under this Plan, any remaining amount payable under this Plan shall be paid to
such Participant's estate when otherwise due hereunder.

     Section 4.8  Hardship Distributions.  If a Participant encounters an
unforeseeable emergency, the Administrative Committee in its absolute discretion
may direct the Employer maintaining such Deferral Account to pay to such
Participant and deduct from such Deferral Account such portion of the amount
then credited to such Deferral Account (including, if appropriate, the entire
amount determined in accordance with Section 4.2) as the Administrative
Committee shall determine to be necessary to alleviate the severe financial
hardship of such Participant caused by such unforeseeable emergency.  For this
purpose, an "unforeseeable emergency" shall be a severe financial hardship to
the Participant resulting from a sudden and unexpected illness or accident of
the Participant or of a dependent of the Participant, loss of the Participant's
property due to casualty, or other similar extraordinary and unforeseeable
circumstances arising as a result of events beyond the control of the
Participant.  The circumstances that will constitute an unforeseeable emergency
will depend upon the facts of each case, but in any case, payment may not be
made to the extent that such hardship is or may be relieved (i) through
reimbursement or compensation by insurance or otherwise, (ii) by liquidation of
the Participant's assets, to the extent liquidation of such assets would not
itself cause severe financial hardship, or (iii) by cessation of deferrals under
the Plan.  No distribution shall be made to a Participant pursuant to this
Section 4.8 unless such Participant requests such a distribution in writing and
provides to the Administrative Committee
<PAGE>
 
such information and documentation with respect to his or her unforeseeable
emergency as may be requested by the Administrative Committee.

     Section 4.9  Change of Distribution Form.  Each Participant may elect
at any time after a Participant's initial Election Period, but no more often
than once during each calendar year, to change the distribution forms elected
with respect to all amounts credited to such Participant's Deferral Account;
provided, however, that such election shall not be effective unless made by the
end of the second calendar year preceding the calendar year in which
distributions are to be made or commence to such Participant pursuant to
Sections 4.4 or 4.5 hereof.


                                  ARTICLE V.

                           AMENDMENT AND TERMINATION

     Section 5.1  Amendment and Termination.  The Compensation Committee
shall have the right and power at any time and from time to time to amend this
Plan, in whole or in part, on behalf of all Employers, and the Board shall have
the right and power at any time to terminate this Plan or any Employer's
participation hereunder.  Any amendment to or termination of this Plan shall be
made by or pursuant to a resolution duly adopted by the Compensation Committee
or the Board, as the case may be, and shall be evidenced by such resolution or
by a written instrument executed by such person as the Compensation Committee or
the Board, as the case may be, shall authorize for such purpose.  Any provision
of this Plan to the contrary notwithstanding, no amendment to or termination of
this Plan shall reduce the amounts actually credited to a Participant's Deferral
Accounts as of the date of such amendment or termination, or further defer the
dates for the payment of such amounts, without the consent of the affected
Participant.  Upon termination of this Plan, the Board, in its sole discretion,
may require the Administrative Committee to calculate final Deferral Account
balances as of such Adjustment Date as it may prescribe, and direct each
Employer to make immediate lump sum payments to each Participant (or beneficiary
in the case of a deceased Participant) with respect to which such Employer
maintains a Deferral Account in the amount determined to be credited to such
Participant's Deferral Account as of such final Adjustment Date.

     Section 5.2  Change of Control.  The preceding provisions of this
Article to the contrary notwithstanding, no action taken on or within two years
following a Change of Control to amend or terminate this Plan shall be effective
unless written consent thereto is obtained from a majority of the Participants.


                                  ARTICLE VI.

                           MISCELLANEOUS PROVISIONS

     Section 6.1  Nature of Plan and Rights.  This Plan is unfunded and
maintained by the Employers primarily for the purpose of providing deferred
compensation for a select group of management or highly compensated employees of
the Employers.  The Deferral Accounts established and maintained under this Plan
by an Employer are for its accounting purposes only and shall not be deemed or
construed to create a trust fund or
<PAGE>
 
security interest of any kind for or to grant a property interest of any kind to
any Participant, designated beneficiary or estate.  The amounts credited by an
Employer to Deferral Accounts maintained under this Plan are and for all
purposes shall continue to be a part of the general assets and liabilities of
such Employer, and to the extent that a Participant, designated beneficiary or
estate acquires a right to receive a payment from such Employer pursuant to this
Plan, such right shall be no greater than the right of any unsecured general
creditor of such Employer.

     Section 6.2  Spendthrift Provision.  No Deferral Account balance or
other right or interest under this Plan of a Participant, designated beneficiary
or estate may be assigned, transferred or alienated, in whole or in part, either
directly or by operation of law, and no such balance, right or interest shall be
liable for or subject to any debt, obligation or liability of such Participant,
designated beneficiary or estate.

     Section 6.3  Employment Noncontractual.  The establishment of this
Plan shall not enlarge or otherwise affect the terms of any Participant's
employment with an Employer, and such Employer may terminate the employment of
such Participant as freely and with the same effect as if this Plan had not been
established.

     Section 6.4  Adoption by Other Employers.  With the consent of the
Compensation Committee, this Plan may be adopted by any Affiliated Company, such
adoption to be effective as of the date specified by such Affiliated Company at
the time of adoption.

     Section 6.5  Claims Procedure.  If any person (hereinafter called the
"Claimant") feels that he or she is being denied a benefit to which he or she is
entitled under this Plan, such Claimant may file a written claim for said
benefit with the Administrative Committee.  Within sixty days following the
receipt of such claim the Administrative Committee shall determine and notify
the Claimant as to whether he or she is entitled to such benefit.  Such
notification shall be in writing and, if denying the claim for benefit, shall
set forth the specific reason or reasons for the denial, make specific reference
to the pertinent provisions of this Plan, and advise the Claimant that he or she
may, within sixty days following the receipt of such notice, in writing request
to appear before the Administrative Committee or its designated representative
for a hearing to review such denial.  Any such hearing shall be scheduled at the
mutual convenience of the Administrative Committee or its designated
representative and the Claimant, and at any such hearing the Claimant and/or his
or her duly authorized representative may examine any relevant documents and
present evidence and arguments to support the granting of the benefit being
claimed.  The final decision of the Administrative Committee with respect to the
claim being reviewed shall be made within sixty days following the hearing
thereon, and Administrative Committee shall in writing notify the Claimant of
said final decision, again specifying the reasons therefor and the pertinent
provisions of this Plan upon which said final decision is based.  The final
decision of the Administrative Committee shall be conclusive and binding upon
all parties having or claiming to have an interest in the matter being reviewed.

     Section 6.6  Reimbursement of Expenses.  In the event that a dispute
arises between a Participant or beneficiary and the Participant's Employer or
the Company with respect to the payment of benefits hereunder and the
Participant or beneficiary is successful in pursuing a benefit to which he
<PAGE>
 
or she is entitled under the terms of the Plan against the Participant's
Employer, the Company or any other party in the course of litigation or
otherwise and incurs attorneys' fees, expenses and costs in connection
therewith, the Participant's Employer and the Company shall reimburse the
Participant or beneficiary for the full amount of any such attorneys' fees,
expenses and costs.

     Section 6.7  Withholding Tax.  There shall be deducted from all
amounts paid under this Plan any taxes required to be withheld by any Federal,
state, local or other government.  The Participant and/or his or her beneficiary
(including his or her estate) shall bear all taxes on amounts paid under this
Plan to the extent that no taxes are withheld, irrespective of whether
withholding is required.

     Section 6.8  Applicable Law.  This Plan shall be governed and
construed in accordance with the internal laws (and not the principles relating
to conflicts of laws) of the State of Texas, except where superseded by federal
law.

     IN WITNESS WHEREOF, this Plan has been executed on this 30th day of
September, 1994 to be effective as of October 1, 1994.

                          DEFERRED COMPENSATION PLAN


     Pursuant to the provisions of Section 5.1 thereof, the ENSERCH Corporation

Deferred Compensation Plan (the "Plan") is hereby amended in the following

respect only:

     Article III of the Plan is hereby amended effective as of January 1, 1995
by adding the following new Section to the end thereof:

          Section 3.6 Deferred Compensation Awards. Effective as of January 1,
     1995, the President of ENSERCH Corporation may enter into "Deferred
     Compensation Award Agreements" with such Eligible Employees as may from
     time to time be approved by the Compensation Committee. Such Agreements
     shall provide for the grant of a deferred compensation award, either fixed
     as to amount or determinable pursuant to a formula, to the Eligible
     Employee subject to such vesting requirements, including performance
     criteria, as shall be approved by the Compensation Committee. The amount of
     any deferred compensation award which vests pursuant to the terms of a
     Deferred Compensation Award Agreement entered into with an Eligible
     Employee shall be credited to such Participant's Deferral Account as of the
     date of such vesting, if such individual is an Eligible Employee as of the
     date of vesting, and any such vested award so credited to a Deferral
     Account shall for all purposes be considered to be, and shall be treated in
     the same manner as, a deferral credited to such Deferral Account. The
     Administrative Committee may maintain separate subaccounts within a
     Participant's Deferral Account for amounts attributable to deferrals and
     deferred compensation awards if separate identification is desired, but the
     amounts credited to any subaccounts shall be treated the same for all
     purposes of this Plan.

     IN WITNESS WHEREOF, this Amendment has been executed this 28th day of
March, 1995.

     In addition to the above, an Eligible Employee may elect to have the

     and President of the Corporation, designated by the Chairman of the
     Compensation Committee) deferred for payment in the manner and at the time

     effective for federal income tax purposes resulting in recognition by
     Participant for federal income tax purposes of an amount credited to
     Participant's Deferral Account hereunder (the "Reclassified Amount")
     earlier than the time payment otherwise would be made to the Participant
     pursuant to this Plan, then the Administrative Committee shall direct the
     Employer maintaining such Participant's Deferral Account to pay to such
     Participant and deduct from such Deferral Account the Reclassified Amount.
     No payment made to a Participant pursuant to this Section 4.10 shall be
     subject to forfeiture as provided in Section 4.6 hereof.

     IN WITNESS WHEREOF, this Amendment has been executed this 23rd day of
September, 1996.

     EIGHTH: Effective as of the date of the distribution of all shares of stock

of Enserch Exploration, Inc. owned by ENSERCH Corporation to the shareholders of

                              ENSERCH CORPORATION
                          DEFERRED COMPENSATION TRUST
                          ---------------------------

     This Trust Agreement made this 30th day of September, 1994, by and between
ENSERCH Corporation, a Texas corporation (the "Company") and Texas Commerce Bank
National Association, a national banking association ( the "Trustee");

          WHEREAS, the Company and certain Affiliated Companies have adopted
     nonqualified deferred compensation plans known as the ENSERCH Corporation
     Deferred Compensation Plan (the "Executive Plan") and the ENSERCH
     Corporation Deferred Compensation Plan for Directors (the "Directors'
     Plan") (collectively hereinafter referred to as the "Plan" or "Plans"); and

          WHEREAS, the Company has incurred or expects to incur liability under
     the terms of such Plans with respect to the individuals participating in
     such Plans; and

          WHEREAS, the Company wishes to establish a trust (hereinafter called
     the "Trust") and to contribute to the Trust assets that shall be held
     therein, subject to the claims of the Company's creditors in the event of
     the Company's Insolvency, as herein defined, until paid to Plan
     Participants and their beneficiaries in such manner and at such times as
     specified in the Plans; and

          WHEREAS, it is the intention of the parties that this Trust shall
     constitute an unfunded arrangement and shall not affect the status of the
     Plans as unfunded plans maintained for the purpose of providing deferred
     compensation for a select group of management or highly compensated
     employees for purposes of Title I of the Employee Retirement Income
     Security Act of 1974; and

          WHEREAS, it is the intention of the Company to make contributions to
     the Trust to provide itself with a source of funds to assist it in the
     meeting of its liabilities under the Plans;

     NOW, THEREFORE, the parties do hereby establish the Trust and agree
that the Trust shall be comprised, held and disposed of as follows:
<PAGE>
 
     Section 1.  Establishment Of Trust.
                 ---------------------- 

     (a) The Company hereby deposits with the Trustee in trust $1,000.00, which
shall become the principal of the Trust to be held, administered and disposed of
by the Trustee as provided in this Trust Agreement.

     (b) The Trust hereby established shall be irrevocable.

     (c) The Trust is intended to be a grantor trust, of which the Company is
the grantor, within the meaning of subpart E, part I, subchapter J, chapter 1,
subtitle A of the Internal Revenue Code of 1986, as amended, and shall be
construed accordingly.

     (d) The principal of the Trust, and any earnings thereon shall be held
separate and apart from other funds of the Company and shall be used exclusively
for the uses and purposes of Plan Participants and general creditors as herein
set forth.  Plan Participants and their beneficiaries shall have no preferred
claim on, or any beneficial ownership interest in, any assets of the Trust.  Any
rights created under the Plans and this Trust Agreement shall be mere unsecured
contractual rights of Plan Participants and their beneficiaries against the
Company.  Any assets held by the Trust will be subject to the claims of the
Company's general creditors under federal and state law in the event of
Insolvency, as defined in Section 4(a) herein.

     (e)  The Company, in its sole discretion, may at any time, or from time to
time, make additional deposits of cash or other property in trust with the
Trustee to augment the principal to be held, administered and disposed of by the
Trustee as provided in this Trust Agreement; provided, however, that the Company
shall contribute to the Trust each calendar year an amount of cash or property
at least equal in value to the total amount of deferrals credited to the
Deferral Accounts of Participants pursuant to the Executive Plan and the
Accounts of Participants pursuant to the Directors' Plan during such calendar
year.

     (f) Any provision of this Trust Agreement to the contrary notwithstanding,
upon a Change of Control, as defined in the Plans, the Company shall (i) as soon
as possible, but in no event more than 30 days following the date of such Change
of Control, make an irrevocable contribution to the Trust in an amount, as
determined by an Independent Committee, as defined below, which when added to
the total value of the assets of the Trust at such time equals the total amount
credited to all Deferral Accounts
<PAGE>
 
under the Executive Plan and all Accounts under the Directors' Plan as of the
date on which the Change of Control occurred, and (ii) during the two-year
period following the date of the Change of Control, make monthly contributions
to the Trust in amounts sufficient, as determined by the Independent Committee,
to maintain the total value of the Trust assets at an amount equal to the total
amount credited to all Deferral Accounts under the Executive Plan and all
Accounts under the Directors' Plan.

     Section 2.  Payments to Plan Participants and their Beneficiaries.
                 ----------------------------------------------------- 

     (a)  The Administrative Committee shall deliver to the Trustee a schedule
(the "Payment Schedule") that indicates the amounts payable with respect to each
Plan Participant (and his or her beneficiaries), that provides a formula or
other instructions acceptable to the Trustee for determining the amounts so
payable, the form in which such amount is to be paid (as provided for or
available under the Plan), and the time of commencement for payment of such
amounts, if known. An updated Payment Schedule shall be provided by the
Administrative Committee to the Trustee periodically, but no less frequently
than once each calendar year. Except as otherwise provided herein, the Trustee
shall make payments to the Plan Participants and their beneficiaries in
accordance with such Payment Schedule. The Trustee shall make provision for the
reporting and withholding of any federal, state or local taxes that may be
required to be withheld with respect to the payment of benefits pursuant to the
terms of the Plans and shall pay amounts withheld to the appropriate taxing
authorities or determine that such amounts have been reported, withheld and paid
by an Employer under the Executive Plan or by the Company under the Directors'
Plan.

     (b) The entitlement of a Plan Participant or his or her beneficiaries to
benefits under the Plan shall be determined by the Administrative Committee or
such other party as may be designated under the Plan, and any claim for such
benefits shall be considered and reviewed under the procedures set out in the
Plan.

     (c) Employers participating in the Executive Plan or the Company with
respect to the Directors' Plan may make payments of benefits directly to Plan
Participants or their beneficiaries as they become due under the terms of the
Plan in lieu of payment from the Trust. The Administrative Committee shall
notify the Trustee of an Employer's or the Company's decision to make payments
of benefits directly prior to the time amounts are
<PAGE>
 
payable to Participants or their beneficiaries.  In addition, if the Trust
assets are not sufficient to make payments of benefits in accordance with the
terms of the Plans, the Company shall make the balance of each such payment as
it falls due.  The Trustee shall notify the Company immediately when Trust
assets are not sufficient to satisfy all payments due.

     (d) Any provision of this Section 2 to the contrary notwithstanding, upon
and after a Change of Control, the Trustee shall make payments to Plan
Participants or their beneficiaries in accordance with the direction of the
Independent Committee rather than the Administrative Committee, regardless of
whether the Trustee has received a Payment Schedule or any other form of
direction from the Administrative Committee to make such payments.

     Section 3. Appointment of Independent Committee. Any provision of this
Trust Agreement to the contrary notwithstanding, upon a Change of Control, an
Independent Committee consisting of at least three members shall be appointed by
the Compensation Committee of the Board of Directors of the Company subject to
the approval of a majority of the Participants of the Plans on the date of such
Change of Control. The Independent Committee shall:

          (a) determine the amount of the irrevocable contributions to be made
     by the Company pursuant to Section 1(f) hereof;

          (b) determine in accordance with the Plans the amounts payable with
     respect to each Plan Participant (and his or her beneficiaries), the form
     in which such amounts are to be paid, and the time of commencement for
     payment of such amounts pursuant to Section 2(a) hereof;

          (c) determine the entitlement of Plan Participants and beneficiaries
     to benefits under the terms of the Plans pursuant to Section 2(b) hereof;

          (d) direct the Trustee to make payments to Plan Participants and their
     beneficiaries pursuant to Section 2 hereof; and

          (e) select a successor Trustee for the Trust if a Trustee resigns or
     is removed on or within two years following the date of a Change of Control
     pursuant to Section 12.
<PAGE>
 
     Section 4. Trustee Responsibility Regarding Payments to Trust Beneficiary
                --------------------------------------------------------------
when the Company Is Insolvent.
- -----------------------------

     (a) The Trustee shall cease payment of benefits to Plan Participants and
their beneficiaries if the Company is Insolvent. The Company shall be considered
"Insolvent" for purposes of this Trust Agreement if (i) the Company is unable to
pay its debts as they become due, or (ii) the Company is subject to a pending
proceeding as a debtor under the United States Bankruptcy Code.

     (b) At all times during the continuance of this Trust, as provided in
Section 1(d) hereof, the principal and income of the Trust shall be subject to
claims of general creditors of the Company under federal and state law as set
forth below.

          (1) The Board of Directors and the Chief Executive Officer of the
     Company shall have the duty to inform the Trustee in writing of the
     Company's Insolvency. If a person claiming to be a creditor of the Company
     alleges in writing to the Trustee that the Company has become Insolvent,
     the Trustee shall determine whether the Company is Insolvent and, pending
     such determination, the Trustee shall discontinue payment of benefits to
     Plan Participants or their beneficiaries.

          (2) Unless the Trustee has actual knowledge of the Company's
     Insolvency, or has received notice from the Company or a person claiming to
     be a creditor alleging that the Company is Insolvent, the Trustee shall
     have no duty to inquire whether the Company is Insolvent. The Trustee may
     in all events rely on such evidence concerning the Company's solvency as
     may be furnished to the Trustee and that provides the Trustee with a
     reasonable basis for making a determination concerning the Company's
     solvency.

          (3) If at any time the Trustee has determined that the Company is
     Insolvent, the Trustee shall discontinue payments to Plan Participants or
     their beneficiaries and shall hold the assets of the Trust for the benefit
     of the Company's general creditors. Nothing in this Trust Agreement shall
     in any way diminish any rights of Plan Participants or their beneficiaries
     to pursue their rights as general creditors of the Company with respect to
     benefits due under the Plan or otherwise.

          (4) The Trustee shall resume the payment of benefits to Plan
     Participants or their beneficiaries in accordance
<PAGE>
 
     with Section 2 of this Trust Agreement only after the Trustee has
     determined that the Company is not Insolvent (or is no longer Insolvent).

     (c) Provided that there are sufficient assets, if the Trustee discontinues
the payment of benefits from the Trust pursuant to Section 4(b) hereof and
subsequently resumes such payments, the first payment following such
discontinuance shall include the aggregate amount of all payments due to Plan
Participants or their beneficiaries under the terms of the Plans for the period
of such discontinuance, less the aggregate amount of any payments made to Plan
Participants or their beneficiaries by the Employers participating in the
Executive Plan or by the Company with respect to the Directors' Plan in lieu of
the payments provided for hereunder during any such period of discontinuance.

     Section 5.  Payments to the Company.
                 ----------------------- 

     (a) Except as provided in Sections 4 and 5(b) hereof, the Company shall
have no right or power to direct the Trustee to return to the Company or to
divert to others any of the Trust assets before payment of all benefits have
been made to Plan Participants and their beneficiaries pursuant to the terms of
the Plans.

     (b) To the extent that the Administrative Committee determines that the
value of the assets in the Trust based upon information provided to the
Administrative Committee by the Trustee, at any time, exceeds 110% of the
amounts credited to Participants' Deferral Accounts under the Executive Plan and
Accounts under the Directors' Plan as of the most recent Adjustment Date plus
any deferrals made since such date, the Trustee shall pay such excess to the
Company upon receipt of written request therefor from the Company; provided,
however, that no such payment of excess assets to the Company shall be made on
or within two years following the date of a Change of Control.

     Section 6.  Investment Authority.
                 -------------------- 

     (a) The Trustee shall have full power and authority to invest and reinvest
the Trust assets, or any part thereof, in such stocks (common or preferred),
bonds, mortgages, notes, interest-bearing deposits (including such deposits with
any corporate trustee acting hereunder), options and contracts for the future or
immediate receipt or delivery of property of any
<PAGE>
 
kind, or other securities, producing or nonproducing oil and gas royalties and
payments and other producing and nonproducing interests in minerals, or in
commodities, life insurance policies, annuity contracts or other property of any
kind or nature whatsoever, whether real, personal or mixed, as the Trustee, in
the Trustee's absolute discretion and judgment, deems appropriate for the Trust,
and to hold cash uninvested at any time and from time to time in such amounts
and to such extent as the Trustee, in the Trustee's absolute discretion and
judgment, deems appropriate for the Trust.  The Trustee shall have full power
and authority to manage, handle, invest, reinvest, sell for cash or credit, or
for part cash or part credit, exchange, hold, dispose of, lease for any period
of time (whether or not longer than the life of the Trust), improve, repair,
maintain, work, develop, use, operate, mortgage, or pledge, all or any part of
the assets and property from time to time constituting any part of the trust
funds held in trust under the Trust; borrow or loan money or securities; write
options and sell securities or other property short or for future delivery;
engage in hedging procedures; buy and sell futures contracts; execute
obligations, negotiable and nonnegotiable; vote shares of stock in person and by
proxy, with or without power of substitution; register investments in the name
of a nominee; sell, convey, lease and/or otherwise deal with any producing or
nonproducing oil, gas and mineral leases or mineral rights, payments and
royalties; pay all reasonable expenses; execute and deliver any deeds,
conveyances, leases, contracts, or written instruments of any character
appropriate to any of the powers or duties of the Trustee, and shall, in
general, have as broad power respecting the management, operation and handling
of the Trust assets and property as if the Trustee were the owner of such assets
and property in the Trustee's own right.  The preceding provisions of this
paragraph to the contrary notwithstanding, the Company shall have the right and
power at any time and from time to time to give the Trustee broad guidelines
within which it shall invest the assets of the Trust; provided, however, that
upon a Change of Control and continuing for two years thereafter, the
Independent Committee, rather than the Company, shall have the sole authority to
exercise such right.

     (b) All rights associated with assets of the Trust shall be exercised by
the Trustee or the person designated by the Trustee, and shall in no event be
exercisable by or rest with Plan Participants.

     (c) The Company shall have the right, at any time, and from time to time in
its sole discretion, to substitute assets of
<PAGE>
 
equal fair market value for any asset held by the Trust; provided, however, that
effective upon a Change in Control and for a period of two years thereafter, any
assets transferred to the Trust in substitution for assets held by the Trust
must consist of cash or marketable securities and the fair market value of the
respective assets shall be determined by the Trustee.  This right is exercisable
by the Company in a nonfiduciary capacity without the approval or consent of any
person in a fiduciary capacity.

     Section 7.  Disposition of Income.  During the term of this Trust, all
                 ---------------------                                     
income received by the Trust, net of expenses and taxes, shall be accumulated
and reinvested.

     Section 8. Accounting by Trustee. The Trustee shall keep accurate and
                ---------------------
detailed records of all investments, receipts, disbursements, and all other
transactions required to be made, including such specific records as shall be
agreed upon in writing between the Company and the Trustee. Within 30 days
following the close of each calendar year and within 30 days after the removal
or resignation of the Trustee, the Trustee shall deliver to the Company a
written account of its administration of the Trust during such year or during
the period from the close of the last preceding year to the date of such removal
or resignation, setting forth all investments, receipts, disbursements and other
transactions effected by it, including a description of all securities and
investments purchased and sold with the cost or net proceeds of such purchases
or sales (accrued interest paid or receivable being shown separately), and
showing all cash, securities and other property held in the Trust at the end of
such year or as of the date of such removal or resignation, as the case may be.

     Section 9.  Responsibility of the Trustee.
                 ----------------------------- 

     (a) The Trustee shall act with the care, skill, prudence and diligence
under the circumstances then prevailing that a prudent person acting in like
capacity and familiar with such matters would use in the conduct of an
enterprise of a like character and with like aims; provided, however, that the
Trustee shall incur no liability to any person for any action taken pursuant to
a direction, request or approval given by the Company which is contemplated by,
and in conformity with, the terms of the Plan or this Trust and is given in
writing by the Company. In the event of a dispute between the Company and a
party, the Trustee may apply to a court of competent jurisdiction to resolve the
dispute.
<PAGE>
 
     (b) If the Trustee undertakes or defends any litigation arising in
connection with this Trust, the Company agrees to indemnify the Trustee against
the Trustee's costs, expenses and liabilities (including, without limitation,
attorneys' fees and expenses) relating thereto and to be primarily liable for
such payments. If the Company does not pay such costs, expenses and liabilities
in a reasonably timely manner, the Trustee may obtain payment from the Trust.

     (c) The Trustee may consult with legal counsel (who may also be counsel for
the Company generally) with respect to any of its duties or obligations
hereunder.

     (d) The Trustee may hire agents, accountants, actuaries, investment
advisors, financial consultants or other professionals to assist it in
performing any of its duties or obligations hereunder.

     (e) The Trustee shall have, without exclusion, all powers conferred on
trustees by applicable law, unless expressly provided otherwise herein;
provided, however, that except as provided in Sections 5(b) and 6(c) hereof, if
an insurance policy is held as an asset of the Trust, the Trustee shall have no
power to name a beneficiary of the policy other than the Trust, to assign the
policy (as distinct from conversion of the policy to a different form) other
than to a successor Trustee, or to loan to any person the proceeds of any
borrowing against such policy.

     (f) Notwithstanding any powers granted to the Trustee pursuant to this
Trust Agreement or applicable law, the Trustee shall not have any power that
could give this Trust the objective of carrying on a business and dividing the
gains therefrom, within the meaning of section 301.7701-2 of the Procedure and
Administrative Regulations promulgated pursuant to the Internal Revenue Code.

     Section 10. Compensation and Expenses of the Trustee. The Trustee shall be
                 ----------------------------------------
paid such reasonable compensation commensurate with the services and
responsibilities involved hereunder as shall from time to time be agreed upon by
the Trustee and the Company. The Company shall pay all administrative and the
Trustee's fees and expenses, but, if not so paid, the fees and expenses shall be
paid from the Trust.

     Section 11.  Resignation and Removal of the Trustee.
                  -------------------------------------- 
<PAGE>
 
     (a) The Trustee may resign at any time by written notice to the Company,
which shall be effective 30 days after receipt of such notice unless the Company
and the Trustee agree otherwise.

     (b) The Trustee may be removed by the Company on 30 days notice or upon
shorter notice accepted by the Trustee; provided, however, that the Trustee may
not be removed by the Company on or within two years following a Change of
Control except with the written consent of a majority of the Participants
entitled to payment of benefits pursuant to the terms of the Plans on the date
of such Change of Control.

     (c) Upon resignation or removal of the Trustee and appointment of a
successor Trustee, all assets shall subsequently be transferred to the successor
Trustee. The transfer shall be completed within 30 days after receipt of notice
of resignation, removal or transfer, unless the Company extends the time limit.

     (d) If the Trustee resigns or is removed, a successor shall be appointed,
in accordance with Section 12 hereof, by the effective date of resignation or
removal under paragraph(s) (a) or (b) of this section. If no such appointment
has been made, the Trustee may apply to a court of competent jurisdiction for
appointment of a successor or for instructions. All expenses of the Trustee in
connection with the proceeding shall be allowed as administrative expenses of
the Trust.

     Section 12.  Appointment of Successor.
                  ------------------------ 

     (a) If the Trustee resigns or is removed in accordance with Section 11(a)
or (b) hereof, the Company may appoint any third party, such as a bank trust
department or other party that may be granted corporate trustee powers under
state law, as a successor to replace the Trustee upon resignation or removal;
provided, however, that if the Trustee resigns or is removed on or within two
years following the date of a Change of Control, the Independent Committee shall
select a successor Trustee in accordance with this Section 12. The appointment
shall be effective when accepted in writing by the new Trustee, who shall have
all of the rights and powers of the former Trustee, including ownership rights
in the Trust assets. The former Trustee shall execute any instrument necessary
or reasonably requested by the Company or the successor Trustee to evidence the
transfer.

     (b) The successor Trustee need not examine the records and acts of any
prior Trustee and may retain or dispose of existing
<PAGE>
 
Trust assets, subject to Sections 8 and 9 hereof.  The successor Trustee shall
not be responsible for and the Company shall indemnify and defend the successor
Trustee from any claim or liability resulting from any action or inaction of any
prior Trustee or from any other past event, or any condition existing at the
time it becomes successor Trustee.

     Section 13. Amendment or Termination.
                 ------------------------ 

     (a) This Trust Agreement may be amended by a written instrument executed by
the Trustee and a representative of the Company so authorized by the
Compensation Committee of the Board of Directors of the Company. Notwithstanding
the foregoing, no such amendment shall conflict with the terms of the Plans or
shall make the Trust revocable.

     (b) The Trust shall not terminate until the date on which Plan Participants
and their beneficiaries are no longer entitled to benefits pursuant to the terms
of the Plans. Upon termination of the Trust any assets remaining in the Trust
shall be returned to the Company.

     (c) Upon written approval of at least two-thirds of the Participants and
beneficiaries entitled to payment of benefits pursuant to the terms of the
Plans, the Company may terminate this Trust prior to the time all benefit
payments under the Plans have been made. All assets in the Trust at termination
shall be returned to the Company.

     (d) This Trust Agreement may not be amended by the Company on or within two
years following the date of a Change of Control, without the written consent of
a majority of the Participants entitled to payment of benefits pursuant to the
terms of the Plans on the date of such Change of Control.

     Section 14.  Miscellaneous.
                  ------------- 

     (a) Any provision of this Trust Agreement prohibited by law shall be
ineffective to the extent of any such prohibition, without invalidating the
remaining provisions hereof.

     (b) Benefits payable to Plan Participants and their beneficiaries under
this Trust Agreement may not be anticipated, assigned (either at law or in
equity), alienated, pledged, encumbered or subjected to attachment, garnishment,
levy, execution or other legal or equitable process.
<PAGE>
 
     (c) This Trust Agreement shall be governed and construed in accordance with
the internal laws (and not the principles relating to conflicts of laws) of the
State of Texas, except where superseded by federal law.

     (d) Unless the context clearly indicates otherwise, when used in this Trust
Agreement:

          (i) "Administrative Committee" shall mean the "Administrative
     Committee" appointed pursuant to each of the Plans.

          (ii) "Participant" shall mean each "Participant" as that term is
     defined in the Executive Plan and each Director who has an amount credited
     to his or her Account under the Directors' Plan or who has elected to have
     all or any portion of his or her Annual Fee deferred under the terms of
     that Plan.

     (e) Except where otherwise defined, capitalized terms used herein shall
have the meaning given to them in the Plans.

     (f) In the event that a dispute arises between a Plan Participant or
beneficiary and the Participant's Employer, the Company or the Trustee with
respect to the payment of amounts from the Trust and the Participant or
beneficiary is successful in pursuing a benefit to which he or she is entitled
under the terms of the Plans and this Trust against the Participant's Employer,
the Company, the Trustee or any other party in the course of litigation or
otherwise and incurs attorneys' fees, expenses and costs in connection
therewith, the Company shall reimburse the Plan Participant or beneficiary for
the full amount of any such attorneys' fees, expenses and costs.

     IN WITNESS WHEREOF, this Agreement has been executed this 30th day of
September, 1994, to be effective as of October 1, 1994.

                          DEFERRED COMPENSATION TRUST

     Pursuant to the provisions of Section 13(a) thereof, the ENSERCH

following respects only:
 
     FIRST: Section l(f) of the Trust is hereby amended by restatement in its
entirety to read as follows:

          (f) Any provision of this Trust Agreement to the contrary
     notwithstanding, upon a Change of Control, as defined in the Plans, the
     Company shall (i) as soon as possible, but in no event more than 30 days
     following the date of such Change of Control, make an irrevocable
     contribution to the Trust in an amount, as determined by an Independent
     Committee, as defined below, which when added to the total value of the
     assets of the Trust at such time equals the total amount credited to all
     Deferral Accounts under the Executive Plan and all Accounts under the
     Directors' Plan as of the date on which the Change of Control occurred, and
     (ii) on and after the date of the Change of Control, make monthly
     contributions to the Trust in amounts sufficient, as determined by the
     Independent Committee, to maintain the total value of the Trust assets at
     an amount equal to the total amount credited to all Deferral Accounts under
     the Executive Plan and all Accounts under the Directors' Plan. Any
     provision of this Trust Agreement to the contrary notwithstanding, on and
     after the date of a Change of Control, the assets of this Trust, including
     any additional contributions made by the Company in accordance with this
     Section l(f) for the period following such Change of Control and any

     the date immediately prior to the date of such Change of Control, subject
     to the claims of general creditors of the Company under federal and state
     law as set forth below.
<PAGE>
 
     SECOND: Section 3 of the Trust is hereby amended by restatement in its
entirety to read as follows:

     Section 3. Appointment of Independent Committee.

          (a) Any provision of this Trust Agreement to the contrary
     notwithstanding, upon a Change of Control, an Independent Committee
     consisting of at least three members shall be appointed by the Board
     subject to the written approval of a majority of the Participants in the
     Plans on the date of such Change of Control. The Independent Committee
     shall:

              (i) determine the amount of the irrevocable contributions to be
          made by the Company pursuant to Section l(f) hereof;

              (ii) determine in accordance with the Plans the amounts payable
          with respect to each Plan Participant (and his or her beneficiaries),
          the form in which such amounts are to be paid, and the time of
          commencement for payment of such amounts pursuant to Section 2(a)
          hereof;

              (iii) determine the entitlement of Plan Participants and
          beneficiaries to benefits under the terms of the Plans pursuant to
          Section 2(b) hereof;

              (iv) direct the Trustee to make payments to Plan Participants and
          their beneficiaries pursuant to Section 2 hereof; and

              (v) select a successor Trustee for the Trust if a Trustee resigns
          or is removed on or after the date of a Change of Control pursuant to
          Section 12.

          (b) Each member of the Independent Committee so appointed shall serve
     in such office until his or her death, resignation or removal. The Board
     may remove any member of the Independent Committee by giving written notice
     thereof to all Plan Participants and all members of the Independent
     Committee; provided, however, that no member of the Independent Committee
     may be removed by the Board on or after a Change of Control except with the
     written consent of a majority of the Plan Participants. Vacancies on the
     Independent Committee shall be filled from time to time by
<PAGE>
 
     the Board subject to the written approval of a majority of the Participants
     in the Plans on the date such vacancy is filled.

          (c) The Independent Committee shall act by a majority of its members
     at the time in office and such action may be taken either by a vote at a
     meeting or in writing without a meeting. The Independent Committee may by
     such majority action authorize any one or more of its members to execute
     any document or documents on behalf of the Independent Committee, in which
     event the Independent Committee shall notify the Trustee in writing of such
     action and the name or names of its member or members so authorized to act.
     Every interpretation, choice, determination or other exercise by the
     Independent Committee of any power or discretion given either expressly or
     by implication to it shall be conclusive and binding upon all parties
     having or claiming to have an interest under the Trust or otherwise
     directly or indirectly affected by such action, without restriction,
     however, on the right of the Independent Committee to reconsider and
     redetermine such action.

          (d) Any provision of this Trust Agreement to the contrary
     notwithstanding, in the event that (i) the Board shall not appoint an
     Independent Committee within 30 days following a Change of Control or a
     majority of the Participants in the Plans do not approve in writing at
     least three members selected by the Board to serve on an Independent
     Committee within such 30-day period or (ii) the Board does not fill a
     vacancy on the Independent Committee within 30 days of the date such office
     becomes vacant or a majority of the Participants in the Plans do not
     approve in writing the Board's selection to fill a vacancy on the
     Independent Committee within such 30-day period, then the Participants in
     the Plans shall elect, by majority vote, up to three individuals to the
     extent necessary to ensure that the Independent Committee consists of three
     members.

     THIRD: Section 5(b) of the Trust is hereby amended by restatement in its
entirety to read as follows:

          (b) To the extent that the Administrative Committee determines that
     the value of the assets in the Trust based upon information provided to the
     Administrative Committee by the Trustee, at any time, exceeds 110% of the
     amounts credited to Participants' Deferral Accounts under the
<PAGE>
 
     Executive Plan and Accounts under the Directors' Plan as of the most recent
     Adjustment Date plus any deferrals made since such date, the Trustee shall
     pay such excess to the Company upon receipt of written request therefor
     from the Company; provided, however, that no such payment of excess assets
     to the Company shall be made on or after the date of a Change of Control
     without the written approval of the Plan Participants.

     FOURTH: Section 6(a) of the Trust is hereby amended by restating the last
sentence thereof in its entirety to read as follows:

     The preceding provisions of this paragraph to the contrary notwithstanding,
     the Company shall have the right and power at any time and from time to
     time to give the Trustee broad guidelines within which it shall invest the
     assets of the Trust; provided, however, that on and after the date of a
     Change of Control, the Independent Committee, rather than the Company,
     shall have the sole authority to exercise such right.

     FIFTH: Section 6(c) of the Trust is hereby amended by restating the first
sentence thereof in its entirety to read as follows:

     The Company shall have the right, at any time, and from time to time in its
     sole discretion, to substitute assets of equal fair market value for any
     asset held by the Trust; provided, however, that on and after the date of a
     Change of Control, any assets transferred to the Trust in substitution for
     assets held by the Trust must consist of cash or marketable securities
     acceptable to the Independent Committee and the fair market value of the
     respective assets shall be determined by the Trustee.

     SIXTH: Section 10 of the Trust is hereby amended by restating the last
sentence thereof in its entirety to read as follows:
<PAGE>
 
     The Company shall pay all administrative and the Trustee's fees and
     expenses, but, if not so paid, such fees and expenses shall be paid from
     the Trust; provided, however, that in the event any such fees and expenses
     are paid from the Trust, the Trustee shall notify the Company in writing
     that such payment has been made and the Company shall reimburse the Trust
     for such payment within 15 days from the date of such notice.

     SEVENTH: Section ll(b) of the Trust is hereby amended by restatement in its

                       RETIREMENT INCOME RESTORATION PLAN
                             OF ENSERCH CORPORATION
                     AND PARTICIPATING SUBSIDIARY COMPANIES

         ENSERCH Corporation, a Texas corporation having its principal
executive office in Dallas, Texas, and its subsidiary, Ebasco Services
Incorporated, hereinafter referred to collectively as the "Companies," hereby
adopt the Retirement Income Restoration Plan of ENSERCH Corporation and
Participating Subsidiary Companies, hereinafter referred to as the "Plan,"
effective January 1, 1984, as follows:

                              Article I
                              ---------
                             Definitions
                             -----------

         Unless qualified by the context or otherwise defined herein, the terms
used herein shall have the meanings assigned to them as applicable under the
provisions of the Retirement and Death Benefit Program of 1969 of ENSERCH
Corporation and Participating Subsidiary Companies and the Ebasco Services
Incorporated Pension Plan for Salaried Employees, as now in effect and as may be
amended hereafter from time to time, hereinafter referred to collectively as the
"Basic Plans" and individually as the "Basic P]an."

         "Limitations" shall mean the reductions imposed on the benefits
provided under the Basic Plans in order to comply with Sections 415 and
401(a)(17) of the Internal Revenue Code of 1986.

         A "Participating Employee" is an employee who is entitled to benefits
under this Plan as a result of Limitations.

         The terms "Change in Control," "Cause," and "Good Reason" shall have
the meanings assigned to them under the provisions of the change in control
agreements dated December 13, 1988, between Messrs. R. G. Fowler, W. T.
Satterwhite, et. al., and the Corporation.

         "Service" shall have the meaning assigned to the terms Benefit Service
or Credited Service in and by the Basic Plans.

                                   Article II
                                   ----------
                                    Purpose
                                    -------
<PAGE>
 
         The purposes of this Plan are (a) to restore benefits to those
employees and their designated beneficiaries who are entitled to receive
benefits under the Basic Plans to the extent that those benefits are, or will
be, reduced by Limitations, and (b) if a Participating Employee's employment is
terminated by the Corporation without Cause or by the Participating Employee for
Good Reason within three years of a Change in Control of the Corporation, to
provide increased retirement benefits as set forth in Section 4.1.

                             Article III
                             -----------
                            Administration
                            --------------

         This Plan shall be administered by the Compensation Committee of the
Board of Directors of ENSERCH Corporation, hereinafter referred to as the
"Committee."  Subject to the provisions of Article VI hereof, the Committee
shall administer this Plan in a manner consistent with the administration of the
1969 Plan, as from time to time amended and in effect, except that this Plan
shall be administered as a plan that is not intended to meet the requirements of
Section 401(a) of the Internal Revenue Code of 1954.  The Committee shall have
full power and authority to interpret, construe, and administer this P]an, and
the Committee's interpretations and constructions hereof, and its actions
hereunder, including all determinations of the amounts and the recipients of
payments to be made hereunder, shall be binding and conclusive with respect to
all persons for all purposes.  No member of the Committee shall be liable to any
person for any action taken or omitted in connection with the interpretation and
administration of this Plan unless attributable to his own willful misconduct or
lack of good faith.

                                   Article IV
                                   ----------
                                    Benefits
                                    --------

         Section 4.1 Amount of Benefits. Subject to the provisions of Section
                     ------------------                                     
4.3 hereof any employee or beneficiary who is entitled to receive a benefit
under a Basic Plan shall be entitled to receive a benefit hereunder equal to the
excess, if any, of:

          (i) the amount of such employee's or beneficiary's benefit under the
              Basic Plan, determined without regard to the Limitations, plus the
              additional benefit that would be payable under the Basic Plan if
              an increase in his Service pursuant to Section 4.2 below is
              applicable, less
<PAGE>
 
          (ii) the amount of the benefit actually payable to the employee or
               beneficiary under the Basic Plan and the amount of reduction of
               Plan payments described in the agreement or agreements between
               the Corporation and the employee relating to any individual
               annuity contracts purchased on behalf of the employee by the
               Corporation.

         Section 4.2 Additional Service. In the event a Participating
                     ------------------                              
Employee's employment is terminated within three (3) years after a Change in
Control of the Corporation by the Corporation without Cause or by the
Participating Employee for Good Reason, his years of Service for purposes of
Section 4.1 shall mean his actual years of Service plus

         (a) in the case of the Chief Executive Officer of the Corporation and
             Participating Employees reporting directly to him, 3 additional
             years of Service; and

         (b) in the case of Participating Employees other than the Chief
             Executive Officer and Participating Employees reporting directly to
             him, 2 additional years of Service;

provided further that (i) in no case shall any Participating Employee as a
result of this Change in Control provision be deemed to have more years of
Service than he would have had if his employment had terminated on the first of
the month coinciding with or Next following his sixty-fifth (65) birthday, and
(ii) the foregoing clauses (a) and (b) shall have no effect on the computation
of a Participating Employee's Average Monthly Earnings or are for purposes of
determining any amounts payable to him under the Basic Plan.

          Section 4. 3 Payment of Benefits. Payment of benefits to an employee
                       -------------------                                   
or beneficiary under this Plan shall be coincident with the payment of benefits
made to the employee or beneficiary under the Basic Plan.

          Section 4.4 Employee's Rights to Benefits. An employee's rights under
                      -----------------------------                           
this Plan, including his rights to vested benefits, shall be the same as his
rights under the Basic Plan, except that no payments due under this Plan shall
be paid from any fund maintained under the Basic Plan.  In no event shall an
individual who is not entitled to benefits under the Basic Plan be entitled to a
benefit under this Plan.  Benefits under this Plan shall be paid sole]y from the
general assets of the Companies, and no
<PAGE>
 
employee or beneficiary shall have any title to or beneficial interest in any
assets of the Companies as a result of this Plan.

                                   Article V
                                   ---------
                           Amendment and Termination
                           -------------------------

         While the Companies intend to maintain this Plan in conjunction with
the Basic Plans for as long as necessary, the Board of Directors of ENSERCH
Corporation reserves the right to amend or terminate this Plan if, in its sole
judgment, amendment or termination is appropriate. However, if the Board should
amend or discontinue this Plan, the Companies shall be liable for all benefits
accrued under this Plan as of the date of such action (determined on the basis
of the assumption that on such date each employee's employment terminated).

                                   Article XI
                                   ----------
                              Rights of Employees
                              -------------------

         The Companies may, but are not required to, set aside funds for their
convenience in order to facilitate the payment of any benefits that may be due
hereunder.  However, in the event that the Companies set aside funds, no
employee or beneficiary shall have any right, title or interest in such funds
while held by the Companies. Any employee or beneficiary who is entitled to
receive a benefit under this Plan shall have the rights solely of a general and
unsecured creditor.

                                  Article VII
                                  -----------
                                 Miscellaneous
                                 -------------

         Section 7.1 Assignment. The interest of an employee or beneficiary may
                     ----------
not be sold, transferred, assigned, or encumbered in any manner, either
voluntarily or involuntarily, and any attempt so to anticipate, alienate sell,
transfer, assign, pledge, encumber, or charge the same shall be null and void;
neither shall the benefits hereunder be liable for or subject to the debts,
contracts, liabilities, engagements, or torts of any person to whom such
benefits or funds are payable, nor shall they be subject to garnishment,
attachment, or other legal or equitable process nor shall they be an asset in
bankruptcy, except that no amount shall be payable hereunder until and unless
any and all amounts representing debts or other obligations owed to any Company
by the individual to whom such amount would otherwise be payable shall have been
fully paid and satisfied.
<PAGE>
 
         Section 7.2  No Employment Rights.  Nothing contained herein shall be
                       --------------------                                    
construed as conferring upon any employee the right to continue in the employ of
the Companies in any capacity.

         Section 7.3 Binding on Companies, Employees and Their Successors. The
                      ----------------------------------------------------    
Plan shall be binding upon and inure to the benefit of the Companies, their

to, the Plan or any modification thereof, including any claim for benefits,
shall be settled by arbitration in Dallas, Texas (or, if applicable law requires
some other forum, then such other forum) in accordance with the rules then
obtaining of the American Arbitration Association. The District Court of Dallas
County, Texas or, as the case may be, the United States District Court for the
Northern District of Texas shall have jurisdiction for all purposes in
connection with arbitration.  Any process or notice of motion or other
application to either of said courts, and any paper in connection with
arbitration, may be served by certified mail, return receipt requested, or by
personal service or in such other manner as may be permissible under the rules
of the applicable court or arbitration tribunal, provided a reasonable time for
appearance is allowed.  Arbitration proceedings must be instituted within one
year after the claimed breach occurred, and the failure to institute arbitration
proceedings within such period shall constitute an absolute bar to the
institution of any proceedings, and a waiver of all claims, with respect to such
breach.

         Section 7.5  Withholding Tax.  There shall be deducted from all
                      ---------------                                  
amounts paid under this Plan any taxes required to be withheld by any Federal,

with and governed by the laws of the State of Texas.

                             OF ENSERCH CORPORATION
                     AND PARTICIPATING SUBSIDIARY COMPANIES


         Pursuant to the provisions of Article V thereof, the Retirement Income
Restoration Plan of ENSERCH Corporation and Participating Subsidiary Companies
(the "Plan") is hereby amended in the following respects only:

         Each of the definitions of "Change in Control," "Cause," and "Good
Reason" is hereby amended as of February 13, 1996 by restatement each in its
entirety to read as follows:

              "Change in Control" or "Change in Control of the Corporation"
         shall mean a change in control of a nature that would be required to be
         reported in response to Item l(a) of the Current Report on Form 8-K, as
         in effect on February 13, 1996, pursuant to Section 13 or 15(d) of the
         Securities Exchange Act of 1934, as amended ("Exchange Act") or would
         have been required to be so reported but for the fact that such event
         had been "previously reported" as that term is defined in Rule 12b-2 of
         Regulation 12B of the Exchange Act; provided that, without limitation
         such a Change in Control
<PAGE>
 
         shall be deemed to have occurred if (a) any Person is or becomes the
         beneficial owner (as defined in Rule 13d-3 under the Exchange Act),
         directly or indirectly, of securities of the Corporation representing
         20% or more of the combined voting power of the Corporation's then
         outstanding securities ordinarily (apart from rights accruing under
         special circumstances) having the right to vote at Sections of
         directors ("Voting Securities"), or (b) individuals who constitute the
         Board on February 13, 1996 (the "Incumbent Board") cease for any reason
         to constitute at least two-thirds thereof, provided that any person
         becoming a director subsequent to February 13, 1996 whose election, or
         nomination for election by the Corporation's shareholders, was approved
         by a vote of at least three-quarters of the directors comprising the
         Incumbent Board (either by a specific vote or by approval of the proxy
         statement of the Corporation in which such person is named as a nominee
         for director, without objection to such nomination) shall be, for
         purposes of this clause (b), considered as though such person were a
         member of the Incumbent Board, or (c) a recapitalization of the
         Corporation occurs which results in either a decrease by 33% or more in
         the aggregate percentage ownership of Voting Securities held by
         Independent Shareholders (on a primary basis or on a fully diluted
         basis
<PAGE>
 
         after giving effect to the exercise of stock options and warrants) or
         an increase in the aggregate percentage ownership of Voting Securities
         hod by non-Independent Shareholders (on a primary basis or on a fully
         diluted basis after giving effect to the exercise of stock options and
         warrants) to greater than 50%, or (d) the shareholders of the
         Corporation have 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 Corporation's assets (including a
         plan of liquidation). For purposes of this definition, the term
         "Person" shall mean and include any individual, corporation,
         partnership, group, association or other "person," as such term is used
         in Section 14(d) of the Exchange Act, other than the Corporation, a
         subsidiary of the Corporation or any employee benefit plan(s) sponsored
         or maintained by the Corporation or any subsidiary thereof, and the
         term "Independent Shareholder" shall mean any shareholder of the
         Corporation except any employee(s) or director(s) of the Corporation or
         any employee benefit plan(s) sponsored or maintained by the Corporation
         or any subsidiary thereof.

              "Cause" or "termination of employment by the Corporation for
         Cause" shall mean termination upon (A) the
<PAGE>
 
         willful and continued failure by a Participating Employee substantially
         to perform his or her duties with the Corporation (other than any such
         failure resulting from his or ha incapacity due to physical or mental
         illness), after a demand for substantial performance is delivered to
         him or her by the Chairman or President of Corporation which
         specifically identifies the manner in which such executive believes
         that he or she has not substantially performed his or her duties, and a
         reasonable period of opportunity for such substantial performance is
         provided, or

              (B) the willful engaging by the Participating Employee in illegal
         misconduct materially and demonstrably injurious to the Corporation.
         For purposes of this paragraph, no act, or failure to act, on the part
         of a Participating Employee shall be considered "willful" unless done,
         or omitted to be done, by the Participating Employee not in good faith
         and without reasonable belief that his or her action or omission was in
         the best interest of the Corporation. Any act, or failure to act, based
         upon authority given pursuant to a resolution duly adopted by the Board
         or based upon the advice of counsel for the Corporation shall be
         conclusively presumed to be done, or omitted to be done, by the
         Participating Employee in good faith and in the best
<PAGE>
 
         interest of the Corporation. Notwithstanding the foregoing, the
         Participating Employee shall not be deemed to have been terminated for
         Cause unless and until there shall have been delivered to him or her a
         copy of a resolution duly adopted by the affirmative vote of not less
         than three-quarters of the entire membership of the Board at a meeting
         of the Board called and held for that purpose (after reasonable notice
         to the Participating Employee and an opportunity for the Participating
         Employee, together with his or her counsel, to be heard before the
         Board), finding that in the good faith opinion of the Board the
         Participating Employee was guilty of conduct set forth above in clauses
         (A) or (B) in this paragraph and specifying the particulars thereof in
         detail.

              "Good Reason" for a Participating Employee to terminate his or her
         employment shall mean:

                  (A) an adverse change in status or position(s) of a
              Participating Employee as an executive of the Corporation as in
              effect immediately prior to a Change in Control, including,
              without limitation, any adverse change in the status or position
              of such Participating Employee as a result of a material
              diminution in his or her duties or responsibilities (other than,
              if
<PAGE>
 
              applicable, any such change directly attributable to the fact that
              less than 50% of the Corporation's voting securities are publicly
              owned or the fact that his or her position becomes a position with
              a subsidiary or division), or a material change in his or her
              business location or the assignment to the Participating Employee
              of any duties or responsibilities which are inconsistent with such
              status or position(s), or a substantial increase in his or her
              business travel or any removal of the Participating Employee from
              or any failure to reappoint or reelect the Participating Employee
              to such position(s) (except in connection with the termination of
              his or her employment for Cause, Disability or Retirement or as a
              result of his or her death or by the Participating Employee other
              than for Good Reason);

                  (B) a reduction by the Corporation in base salary of a
              Participating Employee as in effect immediately prior to the
              Change in Control or in the number of vacation days to which the
              Participating Employee is then entitled under the Corporation's
              normal vacation policy as in effect immediately prior to the
              Change in Control;
<PAGE>
 
                  (C) the taking of any action by the Corporation (including the
              elimination of a plan without providing substitutes therefor or
              the reduction of awards thereunder) that would diminish or the
              failure by the Corporation to take any action which would maintain
              the aggregate projected value of the awards of a Participating
              Employee under the Corporation's bonus, stock option or management
              incentive unit plans in which the Participating Employee was
              participating at the time of a Change in Control of the
              Corporation;

                  (D) the taking of any action by the Corporation that would
              diminish or the failure by the Corporation to take any action
              which would maintain the aggregate value of the benefits provided
              a Participating Employee under the Corporation's medical, health,
              dental, accident, disability, life insurance, stock purchase or
              retirement plans in which the Participating Employee was
              participating at the time of a Change in Control of the
              Corporation;

                  (E) the taking of any action by the Corporation that would
              diminish or the failure of the Corporation
<PAGE>
 
              to take any action that would maintain indemnification or
              insurance for officers' liability; or

                  (F) a failure by the Corporation to obtain from any Successor
              (as defined in a Participating Employee's Change in Control
              Agreement) the assent to such Change in Control Agreement
              contemplated by Section 7 thereof; or

                  (G) any purported termination by the Corporation of the
              employment of a Participating Employee that is not effected
              pursuant to a Notice of Termination satisfying the requirements of
              paragraph (iv) (and, if applicable, paragraph (ii)) of Section 3
              of such Participating Employee's Change in Control Agreement .

          IN WITNESS WHEREOF, this Amendment has been executed as of 13th day of
     February, 1996.

                                     TO THE
                       RETIREMENT INCOME RESTORATION PLAN
                           OF ENSERCH CORPORATION AND
                       PARTICIPATING SUBSIDIARY COMPANIES

         Pursuant to the provisions of Article V thereof, the Retirement Income
Restoration Plan of ENSERCH Corporation and Participating Subsidiary Companies
(the "Plan") is hereby amended in the following respects only:

         FIRST: Article V of the Plan is hereby amended by restatement in its
entirety to read as follows:
                                   Article V
                           Amendment and Termination

             While the Companies intend to maintain this Plan in conjunction
         with the Basic Plans for as long as necessary, the Board of Directors
         of ENSERCH Corporation reserves the right to amend or terminate this
         Plan if, in its sole judgment, amendment or termination is appropriate;
         provided, however, that if the Board should amend or terminate this
         Plan, the Companies shall be liable for all benefits accrued under this
         Plan as of the date of such action determined on the basis of the
         assumption that on such date each employee's employment terminated; and
         provided further, that (i) no amendment may be made to Section 4.2 of
         this Plan within three years after a Change in Control of the
<PAGE>

         and (ii) in the event of a termination of this Plan within three years
         after a Change in Control of the Corporation each Participating
         Employee's benefit hereunder shall be calculated as if such
         Participating Employee's employment was terminated under circumstances
         qualifying him for the additional years of Service provided in Section
         4.2 .

         SECOND: Article VII of the Plan is hereby amended by adding the
following new Section 7.7 to the end thereof:

              Section 7.7 Reimbursement of Expenses. In the event that a dispute
         arises with respect to the payment of benefits hereunder and the
         Participating Employee (or his beneficiary) is successful in pursuing a
         benefit to which he is entitled under the terms of the Plan in the
         course of litigation or otherwise and incurs attorneys' fees, expenses
         and costs in connection therewith, the Companies shall provide
         reimbursement to the Participating Employee (or his beneficiary) for
         the full amount of any such attorneys' fees, expenses and costs.

         THIRD: The Plan is hereby amended by spinning off to a new plan to be
known as the Retirement Income Restoration Plan of Enserch Exploration, Inc. and
Participating Subsidiary Companies, the benefits attributable to employees and
former employees of Enserch Exploration, Inc. effective as of the date of the

                              ENSERCH CORPORATION
                      RETIREMENT INCOME RESTORATION TRUST
                      -----------------------------------


     This Trust Agreement made this 30th day of September, 1994, by and between
ENSERCH Corporation, a Texas corporation (the "Company"), Enserch Exploration,
Inc., a Delaware corporation, New Enserch Exploration, Inc., a Texas
corporation, Enserch Development Corporation, a Texas corporation, Lone Star
Energy Company, a Texas corporation, and Enserch Gas Company, a Texas
Corporation, and Texas Commerce Bank National Association, a national banking
association (the "Trustee");

          WHEREAS, the Company and the participating subsidiaries enumerated on
     the attached Appendix A (the Company and such participating subsidiaries
     are hereinafter referred to as the "Employers") have adopted or may adopt a
     nonqualified deferred compensation plan known as the Retirement Income
     Restoration Plan of ENSERCH Corporation and Participating Subsidiary
     Companies (the "Plan"); and

          WHEREAS, the Employers have incurred or expect to incur liability
     under the terms of such Plan with respect to their respective eligible
     employees participating in such Plan and their beneficiaries; and

          WHEREAS, the Employers wish to establish a trust (hereinafter called
     "Trust"), pursuant to which each Employer will contribute assets that shall
     be held therein in a Separate Account, as herein defined, subject to the
     claims of such Employer's creditors in the event of the Employer's
     Insolvency, as herein defined, until paid to Plan Participants and their
     beneficiaries in such manner and at such times as specified in the Plan;
     and

          WHEREAS, it is the intention of the parties that this Trust shall
     constitute an unfunded arrangement and shall not affect the status of the
     Plan as an unfunded plan maintained for the purpose of providing deferred
     compensation for a select group of management or highly compensated
     employees for purposes of Title I of the Employee Retirement Income
     Security Act of 1974; and
<PAGE>
 
          WHEREAS, it is the intention of the Employers to make contributions to
     the Trust to provide a source of funds to assist them in the meeting of
     their liabilities under the Plan;

     NOW, THEREFORE, the parties do hereby establish the Trust and agree that
the Trust shall be comprised, held and disposed of as follows:

     Section 1.  Establishment Of Trust.
                 ---------------------- 

     (a) The Employers hereby deposit with the Trustee in trust $1,000.00, which
shall become the principal of the Trust to be held, administered and disposed of
by the Trustee as provided in this Trust Agreement.

     (b) The Trust hereby established shall be irrevocable.

     (c) The Trust is intended to be a grantor trust, of which each Employer is
the grantor with respect to its Separate Account, within the meaning of subpart
E, part I, subchapter J, chapter 1, subtitle A of the Internal Revenue Code of
1986, as amended, and shall be construed accordingly.

     (d) The principal of the Trust, and any earnings thereon shall be held
separate and apart from other funds of the Employers and shall be used
exclusively for the uses and purposes of Plan Participants and general creditors
as herein set forth. Plan Participants and their beneficiaries shall have no
preferred claim on, or any beneficial ownership interest in, any assets of the
Trust.  Any rights created under the Plan and this Trust Agreement shall be mere
unsecured contractual rights of Plan Participants and their beneficiaries
against the Employers.  Any assets held in an Employer's Separate Account under
the Trust will be subject to the claims of such Employer's general creditors
under federal and state law in the event of Insolvency, as defined in Section
4(a) herein.

     (e)  The Employers, in their sole discretion, may at any time, or from time
to time, make additional deposits of cash or other property in trust with the
Trustee to augment the principal to be held, administered and disposed of by the
Trustee as provided in this Trust Agreement.  Neither the Trustee nor any Plan
Participant or beneficiary shall have any right to compel such additional
deposits.
<PAGE>
 
     (f) Any provision of this Trust Agreement to the contrary notwithstanding,
upon a Change of Control of the Company, as defined in the Plan, each Employer
shall (i) as soon as possible, but in no event more than 30 days following the
date of such Change of Control, make an irrevocable contribution to the Trust in
an amount, as determined by an Independent Committee, as defined below, which
when added to the total value of the assets of the Employer's Separate Account
under the Trust at such time equals the total present value of all benefits
accrued under the Plan with respect to such Employer's respective Plan
Participants and beneficiaries as of the date on which the Change of Control
occurred, and (ii) during the two-year period following the date of the Change
of Control, make monthly contributions to the Trust in amounts sufficient, as
determined by the Independent Committee, to maintain the total value of the
assets in the Employer's Separate Account under the Trust at an amount equal to
the total present value of all benefits accrued under the Plan with respect to
such Employer's respective Plan Participants and beneficiaries.

     (g)  Any provision of this Trust Agreement to the contrary notwithstanding,
in the event that a Participant transfers employment between Employers
participating in this Trust, (i) the Employer from which the Participant is
transferred shall as soon as possible, but in no event more than 30 days
following the date of such transfer, make an irrevocable contribution to the
Trust in an amount, as determined by the Company, which equals the total present
value of the benefits accrued under the Plan with respect to such transferring
Participant as of the date on which the transfer occurred or, if less, an amount
equal to the total present value of all benefits accrued under the Plan with
respect to such Employer's respective Plan Participants and beneficiaries, and
(ii) immediately following the Employer's contribution described in (i), the
Trustee shall transfer assets from the transferring Employer's Separate Account
to the Separate Account of the Employer to which the Participant is being
transferred in an amount equal to the total present value of the benefits
accrued under the Plan with respect to such transferring Participant as of the
date on which the transfer occurred.

     Section 2.  Payments to Plan Participants and their Beneficiaries.
                 ----------------------------------------------------- 

     (a) The Company shall deliver to the Trustee a schedule (the "Payment
Schedule") that indicates the amounts payable with respect to each Plan
Participant (and his or her beneficiaries) and the Separate Account of the
Employer from which such amounts
<PAGE>
 
are payable, that provides a formula or other instructions acceptable to the
Trustee for determining the amounts so payable, the form in which such amount is
to be paid (as provided for or available under the Plan), and the time of
commencement for payment of such amounts.  An updated Payment Schedule shall be
provided by the Company to the Trustee periodically, but no less frequently than
once each calendar year.  Except as otherwise provided herein, the Trustee shall
make payments to the Plan Participants and their beneficiaries in accordance
with such Payment Schedule.  The Trustee shall make provision for the reporting
and withholding of any federal, state or local taxes that may be required to be
withheld with respect to the payment of benefits pursuant to the terms of the
Plan and shall pay amounts withheld to the appropriate taxing authorities or
determine that such amounts have been reported, withheld and paid by the
Employer.

     (b) The entitlement of a Plan Participant or his or her beneficiaries to
benefits under the Plan shall be determined by the Company or such other party
as may be designated under the Plan, and any claim for such benefits shall be
considered and reviewed under the procedures set out in the Plan.

     (c) The Employers may make payments of benefits directly to Plan
Participants or their beneficiaries as they become due under the terms of the
Plan in lieu of payment from the Trust.  The Company shall notify the Trustee of
an Employer's decision to make payments of benefits directly prior to the time
amounts are payable to Participants or their beneficiaries.  In addition, if the
assets of an Employer's Separate Account under the Trust are not sufficient to
make payments of benefits to its respective Plan Participants and beneficiaries
in accordance with the terms of the Plan, such Employer shall make the balance
of each such payment as it falls due, and the Separate Accounts of other
Employers hereunder shall not be liable for the payment of such benefits.  The
Trustee shall notify the Company immediately when the assets in an Employer's
Separate Account under the Trust are not sufficient to satisfy all payments due.

     (d) Any provision of this Section 2 to the contrary notwithstanding, upon
and after a Change of Control of the Company, the Trustee shall make payments to
Plan Participants or their beneficiaries in accordance with the direction of the
Independent Committee rather than the Company, regardless of whether the Trustee
has received a Payment Schedule or any other form of direction from the Company
to make such payments.
<PAGE>
 
     Section 3.  Appointment of Independent Committee.  Any provision of this
                 ------------------------------------                        
Trust Agreement to the contrary notwithstanding, upon a Change of Control of the
Company, an Independent Committee consisting of at least three members shall be
appointed by the Compensation Committee of the Board of Directors of the Company
(the "Compensation Committee") subject to the approval of a majority of the
Participants in the Plan on the date of such Change of Control.  The Independent
Committee shall:

          (a) determine the amount of the irrevocable contributions to be made
     by each Employer pursuant to Section 1(f) hereof;

          (b) determine in accordance with the Plan the amounts payable with
     respect to each Plan Participant (and his or her beneficiaries), the form
     in which such amounts are to be paid, and the time of commencement for
     payment of such amounts pursuant to Section 2(a) hereof;

          (c) determine the entitlement of Plan Participants and beneficiaries
     to benefits under the terms of the Plan pursuant to Section 2(b) hereof;

          (d) direct the Trustee to make payments to Plan Participants and their
     beneficiaries pursuant to Section 2 hereof; and

          (e) select a successor Trustee for the Trust if a Trustee resigns or
     is removed on or within two years following the date of a Change of Control
     of the Company pursuant to Section 12.

     Section 4.  Trustee Responsibility Regarding Payments to Trust Beneficiary
                 --------------------------------------------------------------
when an Employer Is Insolvent.
- ----------------------------- 

     (a) The Trustee shall cease payment of benefits to Plan Participants and
their beneficiaries if the Participants' Employer is Insolvent.  An Employer
shall be considered "Insolvent" for purposes of this Trust Agreement if (i) the
Employer is unable to pay its debts as they become due, or (ii) the Employer is
subject to a pending proceeding as a debtor under the United States Bankruptcy
Code.

     (b) At all times during the continuance of this Trust, as provided in
Section 1(d) hereof, the principal and income of each Employer's Separate
Account under the Trust shall be subject to
<PAGE>
 
claims of general creditors of the Employer under federal and state law as set
forth below.

          (1) The Board of Directors and the Chief Executive Officer of an
     Employer shall have the duty to inform the Trustee in writing of the
     Employer's Insolvency. If a person claiming to be a creditor of an Employer
     alleges in writing to the Trustee that the Employer has become Insolvent,
     the Trustee shall determine whether the Employer is Insolvent and, pending
     such determination, the Trustee shall discontinue payment of benefits to
     the Employer's respective Plan Participants or their beneficiaries.

          (2) Unless the Trustee has actual knowledge of an Employer's
     Insolvency, or has received notice from the Employer or a person claiming
     to be a creditor alleging that the Employer is Insolvent, the Trustee shall
     have no duty to inquire whether the Employer is Insolvent. The Trustee may
     in all events rely on such evidence concerning the Employer's solvency as
     may be furnished to the Trustee and that provides the Trustee with a
     reasonable basis for making a determination concerning the Employer's
     solvency.

          (3) If at any time the Trustee has determined that an Employer is
     Insolvent, the Trustee shall discontinue payments to the Employer's
     respective Plan Participants or their beneficiaries and shall hold the
     assets of the Employer's Separate Account under the Trust for the benefit
     of the Employer's general creditors. Nothing in this Trust Agreement shall
     in any way diminish any rights of Plan Participants or their beneficiaries
     to pursue their rights as general creditors of an Employer with respect to
     benefits due under the Plan or otherwise.

          (4) The Trustee shall resume the payment of benefits to an Employer's
     respective Plan Participants or their beneficiaries in accordance with
     Section 2 of this Trust Agreement only after the Trustee has determined
     that the Employer is not Insolvent (or is no longer Insolvent).

     (c) Provided that there are sufficient assets in an Employer's Separate
Account under the Trust, if the Trustee discontinues the payment of benefits
from the Trust pursuant to Section 4(b) hereof and subsequently resumes such
payments, the first payment following such discontinuance shall include the
aggregate amount of all payments due to Plan Participants or their beneficiaries
under the terms of the Plan for the period of
<PAGE>
 
such discontinuance, less the aggregate amount of any payments made to Plan
Participants or their beneficiaries by the Employer in lieu of the payments
provided for hereunder during any such period of discontinuance.

     Section 5.  Payments to the Employers.
                 ------------------------- 

     (a) Except as provided in Sections 4 and 5(b) hereof, the Employers shall
have no right or power to direct the Trustee to return to the Employers or to
divert to others any of the Trust assets before payment of all benefits have
been made to Plan Participants and their beneficiaries pursuant to the terms of
the Plan.

     (b) To the extent that an Employer determines that the value of the assets
in its Separate Account under the Trust based upon information provided to the
Employer by the Trustee, at any time, exceeds 110% of the present value of the
benefits accrued under the Plan by the Employer's respective Plan Participants,
the Trustee shall pay such excess to the Employer upon receipt of written
request therefor from the Company; provided, however, that no such payment of
excess assets to the Employer shall be made on or within two years following the
date of a Change of Control of the Company.

     Section 6.  Investment Authority.
                 -------------------- 

     (a)  The Trustee shall establish and maintain a separate account within the
Trust for each Employer (the "Separate Account").  All amounts deposited with
the Trustee by an Employer shall be allocated to such Employer's Separate
Account.  The Trustee shall invest, reinvest and administer the assets allocated
to each Employer's Separate Account under the Trust as an individual, separate
fund.  At the end of each calendar year and at such other times as the Company
may determine, the Trustee shall determine the fair market value of the assets
of each Employer's Separate Account.  The Separate Account of each Employer
shall be adjusted to reflect the income collected, realized and unrealized
profits and losses, expenses and all other transactions affecting such Separate
Account for the valuation period then ended.

     (b) The Trustee shall have full power and authority to invest and reinvest
the assets of each Employer's Separate Account, or any part thereof, in such
stocks (common or preferred), bonds, mortgages, notes, interest-bearing deposits
(including such deposits with any corporate trustee acting
<PAGE>
 
hereunder), options and contracts for the future or immediate receipt or
delivery of property of any kind, or other securities, producing or nonproducing
oil and gas royalties and payments and other producing and nonproducing
interests in minerals, or in commodities, life insurance policies, annuity
contracts or other property of any kind or nature whatsoever, whether real,
personal or mixed, as the Trustee, in the Trustee's absolute discretion and
judgment, deems appropriate for the Trust, and to hold cash uninvested at any
time and from time to time in such amounts and to such extent as the Trustee, in
the Trustee's absolute discretion and judgment, deems appropriate for the Trust.
The Trustee shall have full power and authority to manage, handle, invest,
reinvest, sell for cash or credit, or for part cash or part credit, exchange,
hold, dispose of, lease for any period of time (whether or not longer than the
life of the Trust), improve, repair, maintain, work, develop, use, operate,
mortgage, or pledge, all or any part of the assets and property from time to
time constituting any part of the trust funds held in trust under the Trust;
borrow or loan money or securities; write options and sell securities or other
property short or for future delivery; engage in hedging procedures; buy and
sell futures contracts; execute obligations, negotiable and nonnegotiable; vote
shares of stock in person and by proxy, with or without power of substitution;
register investments in the name of a nominee; sell, convey, lease and/or
otherwise deal with any producing or nonproducing oil, gas and mineral leases or
mineral rights, payments and royalties; pay all reasonable expenses; execute and
deliver any deeds, conveyances, leases, contracts, or written instruments of any
character appropriate to any of the powers or duties of the Trustee, and shall,
in general, have as broad power respecting the management, operation and
handling of the Trust assets and property as if the Trustee were the owner of
such assets and property in the Trustee's own right.  The preceding provisions
of this paragraph to the contrary notwithstanding, the Company shall have the
right and power at any time and from time to time to give the Trustee broad
guidelines within which it shall invest the assets of the Trust; provided,
however, that upon a Change of Control of the Company and continuing for two
years thereafter, the Independent Committee, rather than the Company, shall have
the sole authority to exercise such right.

     (c) All rights associated with assets of the Trust shall be exercised by
the Trustee or the person designated by the Trustee, and shall in no event be
exercisable by or rest with Plan Participants.
<PAGE>
 
     (d) Each Employer shall have the right, at any time, and from time to time
in its sole discretion, to substitute assets of equal fair market value for any
asset held in its Separate Account under the Trust provided, however, that
effective upon a Change of Control of the Company and for a period of two years
thereafter, any assets transferred to the Trust in substitution for assets held
in an Employer's Separate Account under the Trust must consist of cash or
marketable securities and the fair market value of the respective assets shall
be determined by the Trustee.  This right is exercisable by the Employer in a
nonfiduciary capacity without the approval or consent of any person in a
fiduciary capacity.

     Section 7.  Disposition of Income.  During the term of this Trust, all
                 ---------------------                                     
income received by the Trust, net of expenses and taxes, shall be accumulated
and reinvested.

     Section 8.  Accounting by Trustee.  The Trustee shall keep accurate and
                 ---------------------                                      
detailed records of all investments, receipts, disbursements, and all other
transactions required to be made, including such specific records as shall be
agreed upon in writing between the Company and the Trustee.  Within 30 days
following the close of each calendar year and within 30 days after the removal
or resignation of the Trustee, the Trustee shall deliver to the Company a
written account of its administration of the Trust and to each Employer a
written account of its administration of the Employer's Separate Account during
such year or during the period from the close of the last preceding year to the
date of such removal or resignation, setting forth all investments, receipts,
disbursements and other transactions effected by it, including a description of
all securities and investments purchased and sold with the cost or net proceeds
of such purchases or sales (accrued interest paid or receivable being shown
separately), and showing all cash, securities and other property held in the
Trust at the end of such year or as of the date of such removal or resignation,
as the case may be.

     Section 9.  Responsibility of the Trustee.
                 ----------------------------- 

     (a) The Trustee shall act with the care, skill, prudence and diligence
under the circumstances then prevailing that a prudent person acting in like
capacity and familiar with such matters would use in the conduct of an
enterprise of a like character and with like aims; provided, however, that the
Trustee shall incur no liability to any person for any action taken pursuant to
a direction, request or approval given by an Employer
<PAGE>
 
which is contemplated by, and in conformity with, the terms of the Plan or this
Trust and is given in writing by the Employer. In the event of a dispute between
an Employer and a party, the Trustee may apply to a court of competent
jurisdiction to resolve the dispute.

     (b) If the Trustee undertakes or defends any litigation arising in
connection with this Trust, the Employers agree to indemnify the Trustee against
the Trustee's costs, expenses and liabilities (including, without limitation,
attorneys' fees and expenses) relating thereto and to be primarily liable for
such payments.  If the Employers do not pay such costs, expenses and liabilities
in a reasonably timely manner, the Trustee may obtain payment from the Trust.

     (c) The Trustee may consult with legal counsel (who may also be counsel for
the Employers generally) with respect to any of its duties or obligations
hereunder.

     (d) The Trustee may hire agents, accountants, actuaries, investment
advisors, financial consultants or other professionals to assist it in
performing any of its duties or obligations hereunder.

     (e) The Trustee shall have, without exclusion, all powers conferred on
trustees by applicable law, unless expressly provided otherwise herein;
provided, however, that except as provided in Sections 5(b) and 6(d) hereof, if
an insurance policy is held as an asset of the Trust, the Trustee shall have no
power to name a beneficiary of the policy other than the Trust, to assign the
policy (as distinct from conversion of the policy to a different form) other
than to a successor Trustee, or to loan to any person the proceeds of any
borrowing against such policy.

     (f) Notwithstanding any powers granted to the Trustee pursuant to this
Trust Agreement or applicable law, the Trustee shall not have any power that
could give this Trust the objective of carrying on a business and dividing the
gains therefrom, within the meaning of section 301.7701-2 of the Procedure and
Administrative Regulations promulgated pursuant to the Internal Revenue Code.

     Section 10.  Compensation and Expenses of the Trustee.  The Trustee shall
                  ----------------------------------------                    
be paid such reasonable compensation commensurate with the services and
responsibilities involved hereunder as shall from time to time be agreed upon by
the Trustee and the Company.  The Employers shall pay all administrative and the
<PAGE>
 
Trustee's fees and expenses, but, if not so paid, the fees and expenses shall be
paid from the Trust.

     Section 11.  Resignation and Removal of the Trustee.
                  -------------------------------------- 

     (a) The Trustee may resign at any time by written notice to the Company,
which shall be effective 30 days after receipt of such notice unless the Company
and the Trustee agree otherwise.

     (b) The Trustee may be removed by the Company on 30 days notice or upon
shorter notice accepted by the Trustee; provided, however, that the Trustee may
not be removed by the Company on or within two years following a Change of
Control of the Company except with the written consent of a majority of the
Participants entitled to payment of benefits pursuant to the terms of the Plan
on the date of such Change of Control.

     (c) Upon resignation or removal of the Trustee and appointment of a
successor Trustee, all assets shall subsequently be transferred to the successor
Trustee.  The transfer shall be completed within 30 days after receipt of notice
of resignation, removal or transfer, unless the Company extends the time limit.

     (d) If the Trustee resigns or is removed, a successor shall be appointed,
in accordance with Section 12 hereof, by the effective date of resignation or
removal under paragraph(s) (a) or (b) of this section.  If no such appointment
has been made, the Trustee may apply to a court of competent jurisdiction for
appointment of a successor or for instructions.  All expenses of the Trustee in
connection with the proceeding shall be allowed as administrative expenses of
the Trust.

     Section 12.  Appointment of Successor.
                  ------------------------ 

     (a) If the Trustee resigns or is removed in accordance with Section 11(a)
or (b) hereof, the Company may appoint any third party, such as a bank trust
department or other party that may be granted corporate trustee powers under
state law, as a successor to replace the Trustee upon resignation or removal;
provided, however, that if the Trustee resigns or is removed on or within two
years following the date of a Change of Control of the Company, the Independent
Committee shall select a successor Trustee in accordance with this Section 12.
The appointment shall be effective when accepted in writing by the new Trustee,
who shall have all of the rights and powers of the former Trustee, including
ownership rights in the Trust assets.  The former Trustee shall execute any
instrument necessary or
<PAGE>
 
reasonably requested by the Company or the successor Trustee to evidence the
transfer.

     (b) The successor Trustee need not examine the records and acts of any
prior Trustee and may retain or dispose of existing Trust assets, subject to
Sections 8 and 9 hereof.  The successor Trustee shall not be responsible for and
the Employers shall indemnify and defend the successor Trustee from any claim or
liability resulting from any action or inaction of any prior Trustee or from any
other past event, or any condition existing at the time it becomes successor
Trustee.

     Section 13.  Amendment or Termination.
                  ------------------------ 

     (a) This Trust Agreement may be amended by a written instrument executed by
the Trustee and the Company. Notwithstanding the foregoing, no such amendment
shall conflict with the terms of the Plan or shall make the Trust revocable.

     (b) The Trust shall not terminate until the date on which Plan Participants
and their beneficiaries are no longer entitled to benefits pursuant to the terms
of the Plan.  Upon termination of the Trust any assets remaining in an
Employer's Separate Account under the Trust shall be returned to such Employer.

     (c) Upon written approval of at least two-thirds of the Participants and
beneficiaries entitled to payment of benefits pursuant to the terms of the Plan,
the Company may terminate this Trust prior to the time all benefit payments
under the Plan have been made.  All assets in an Employer's Separate Account
under the Trust at termination shall be returned to such Employer.

     (d) The Company may terminate this Trust with respect to the Separate
Account of any Employer with the written approval of at least two-thirds of the
Employer's respective Plan Participants and beneficiaries who are entitled to
payment of benefits pursuant to the terms of the Plan.  All assets in an
Employer's Separate Account under the Trust on the date of such termination
shall be returned to such Employer.

     (e) This Trust Agreement may not be amended by the Company on or within two
years following the date of a Change of Control of the Company, without the
written consent of a majority of the Participants entitled to payment of
benefits pursuant to the terms of the Plan on the date of such Change of
Control.
<PAGE>
 
     Section 14.  Miscellaneous.
                  ------------- 

     (a) Any provision of this Trust Agreement prohibited by law shall be
ineffective to the extent of any such prohibition, without invalidating the
remaining provisions hereof.

     (b) Benefits payable to Plan Participants and their beneficiaries under
this Trust Agreement may not be anticipated, assigned (either at law or in
equity), alienated, pledged, encumbered or subjected to attachment, garnishment,
levy, execution or other legal or equitable process.

     (c) This Trust Agreement shall be governed and construed in accordance with
the internal laws (and not the principles relating to conflicts of laws) of the
State of Texas, except where superseded by federal law.

     (d) Except where otherwise defined, capitalized terms used herein shall
have the meaning given to them in the Plan.

     (e) In the event that a dispute arises between a Plan Participant or
beneficiary and the Participant's Employer, the Company or the Trustee with
respect to the payment of amounts from the Trust and the Participant or
beneficiary is successful in pursuing a benefit to which he or she is entitled
under the terms of the Plan and this Trust against the Participant's Employer,
the Company, the Trustee or any other party in the course of litigation or
otherwise and incurs attorneys' fees, expenses and costs in connection
therewith, the Participant's Employer shall reimburse the Plan Participant or
beneficiary for the full amount of any such attorneys' fees, expenses and costs.

     (f) Upon the written consent of the Company delivered to the Trustee, any
other affiliate of the Company which adopts the Plan may become a party to this
Trust by delivering to the Trustee a certified copy of a resolution of its board
of directors or other governing authority adopting this Trust.  For purposes of
this Trust, any such affiliate which adopts this Trust with the written consent
of the Company shall be an Employer hereunder.

                              ENSERCH CORPORATION
                      RETIREMENT INCOME RESTORATION TRUST

     Pursuant to the provisions of Section 13(a) thereof, the ENSERCH
Corporation Retirement Income Restoration Trust (the "Trust") is hereby amended
in the following respects only: FIRST: Section l(f) of the Trust is hereby
amended by restatement in its entirety to read as follows:

          (f) Any provision of this Trust Agreement to the contrary
     notwithstanding, upon a Change of Control of the Company, as defined in the
     Plan, each Employer shall (i) as soon as possible, but in no event more
     than 30 days following the date of such Change of Control, make an
     irrevocable contribution to the Trust in an amount, as determined by an
     Independent Committee, as defined below, which when added to the total
     value of the assets of the Employer's Separate Account under the Trust at
     such time equals the total present value of all benefits accrued under the
     Plan with respect to such Employer's respective Plan Participants and
     beneficiaries as of the date on which the Change of Control occurred, and
     (ii) on and after the date of the Change of Control, make monthly
     contributions to the Trust in amounts sufficient, as determined by the
     Independent Committee, to maintain the total value of the assets in the
     Employer's Separate Account under the Trust at an amount equal to the total
     present value of all benefits accrued under the Plan with respect to such
     Employer's respective Plan Participants and beneficiaries. Any provision of
     this Trust Agreement to the contrary notwithstanding, on and after the date
     of a Change of Control of the Company, such portion of the assets in each
     Separate Account of an Employer under this Trust as of the date of the
     Change of Control equal in value to the total present value of such
     Employer's Plan Participants' accrued benefits under the Plan as of such
     date shall be segregated into a subaccount of such Separate Account to be
     used and held exclusively for the benefit of such Employer's Plan
     Participants (and their beneficiaries) as of the date immediately prior to
     the date of such Change of Control, subject to the claims of general
<PAGE>
 
     creditors of the Employer under federal and state law as set forth below.

     SECOND: Section 3 of the Trust is hereby amended by restatement in its 
entirety to read as follows:

     Section 3. Appointment of Independent Committee.

          (a) Any provision of this Trust Agreement to the contrary
     notwithstanding, upon a Change of Control of the Company, an Independent
     Committee consisting of at least three members shall be appointed by the
     Board of Directors of ENSERCH Corporation (the "Board") subject to the
     written approval of a majority of the Plan Participants. The Independent
     Committee shall:

               (i) determine the assumptions to be used in calculating present
          values of benefits accrued for purposes of this Trust;

               (ii) determine the amount of the irrevocable contributions to be
          made by each Employer pursuant to Section l(f) hereof;

               (iii) determine in accordance with the Plan the amounts payable
          with respect to each Plan Participant (and his or her beneficiaries),
          the form in which such amounts are to be paid, and the time of
          commencement for payment of such amounts pursuant to Section 2(a)
          hereof;

               (iv) determine the entitlement of Plan Participants and
          beneficiaries to benefits under the terms of the Plan pursuant to
          Section 2(b) hereof;

               (v) direct the Trustee to make payments to Plan Participants and
          their beneficiaries pursuant to Section 2 hereof; and

               (vi) select a successor Trustee for the Trust if a Trustee
          resigns or is removed on or after the date of a Change of Control of
          the Company pursuant to Section 12.

          (b) Each member of the Independent Committee so appointed shall serve
     in such office until his or her death, resignation or removal. The Board
     may remove any member of the Independent Committee by giving written notice
     thereof to all Plan
<PAGE>
 
     Participants and all members of the Independent Committee; provided,
     however, that no member of the Independent Committee may be removed by the
     Board on or after a Change of Control of the Company except with the
     written consent of a majority of the Plan Participants. Vacancies on the
     Independent Committee shall be filled from time to time by the Board
     subject to the written approval of a majority of the Plan Participants on
     the date such vacancy is filled.

          (c) The Independent Committee shall act by a majority of its members
     at the time in office and such action may be taken either by a vote at a
     meeting or in writing without a meeting. The Independent Committee may by
     such majority action authorize any one or more of its members to execute
     any document or documents on behalf of the Independent Committee, in which
     event the Independent Committee shall notify the Trustee in writing of such
     action and the name or names of its member or members so authorized to act.
     Every interpretation, choice, determination or other exercise by the
     Independent Committee of any power or discretion given either expressly or
     by implication to it shall be conclusive and binding upon all parties
     having or claiming to have an interest under the Trust or otherwise
     directly or indirectly affected by such action, without restriction,
     however, on the right of the Independent Committee to reconsider and
     redetermine such action.

          (d) Any provision of this Trust Agreement to the contrary
     notwithstanding, in the event that (i) the Board shall not appoint an
     Independent Committee within 30 days following a Change of Control of the
     Company or a majority of the Participants in the Plan do not approve in
     writing at least three members selected by the Board to serve on an
     Independent Committee within such 30-day period or (ii) the Board does not
     fill a vacancy on the Independent Committee within 30 days of the date such
     office becomes vacant or a majority of the Participants in the Plan do not
     approve in writing the Board's selection to fill a vacancy on the
     Independent Committee within such 30-day period, then the Participants in
     the Plan shall elect, by majority vote, up to three individuals to the
     extent necessary to ensure that the Independent Committee consists of three
     members.

     THIRD: Section 5(b) of the Trust is hereby amended by restatement in its

<PAGE>
 
          (b) To the extent that an Employer determines that the value of the
     assets in its Separate Account under the Trust based upon information
     provided to the Employer by the Trustee, at any time, exceeds 110` of the
     present value of the benefits accrued under the Plan by the Employer's
     respective Plan Participants, the Trustee shall pay such excess to the
     Employer upon receipt of written request therefor from the Company;
     provided, however, that no such payment of excess assets to the Employer
     shall be made on or after the date of a Change of Control of the Company
     without the written approval of the Participants in the Plan.

     FOURTH: Section 6(b) of the Trust is hereby amended by restating the last
sentence thereof in its entirety to read as follows:

     the Company shall have the right and power at any time and from time to
     time to give the Trustee broad guidelines within which it shall invest the
     assets of the Trust; provided, however, that on and after the date of a
     Change of Control of the Company, the Independent Committee, rather than
     the Company, shall have the sole authority to exercise such right.

     FIFTH: Section 6(d) of the Trust is hereby amended by restating the first
sentence thereof in its entirety to read as follows:

     Each Employer shall have the right, at any time, and from time to time in
     its sole discretion, to substitute assets of equal fair market value for
     any asset held in its Separate Account under the Trust; provided, however,
     that on and after the date of a Change of Control of the Company, any
     assets transferred to the Trust in substitution for assets held in an
     Employer's Separate Account under the Trust must consist of cash or
     marketable securities acceptable to the Independent Committee and the fair
     market value of the respective assets shall be determined by the Trustee.

     in writing that such payment has been made and the Employers shall
     reimburse the Trust for such payment within 15 days from the date of such

     SEVENTH: Section 10 of the Trust is hereby amended by restating the last
sentence thereof in its entirety to read as follows:

     the Trust; provided, however, that in the event any such fees and expenses
     are paid from the Trust, the Trustee shall notify the Employers in writing
     that such payment has been made and the Employers shall reimburse the Trust
     for such payment within 15 days from the date of such notice.

     of Control of the Company except with the written consent of a majority of
     the Plan Participants.

     NINTH: Section 12(a) of the Trust is hereby amended by restating the first
sentence thereof in its entirety to read as follows:

     under state law, as a successor to replace the Trustee upon resignation or
     removal; provided, however, that if the Trustee resigns or is removed on or
     after the date of a Change of Control of the Company, the Independent
     Committee shall select a successor Trustee in accordance with this Section
     12.

     TENTH: Section 13(e) of the Trust is hereby amended by restatement in its

                              EMPLOYMENT AGREEMENT

     THIS AGREEMENT by and between ENSERCH EXPLORATION, INC. (the "Company") and
____________________ the "Executive") is entered into on this
_____________________, 19______.

                                  WITNESSETH:
                                  -----------

     WHEREAS, the Company desires to employ the Executive, and the Executive is
willing to serve in the employ of the Company, upon the terms and conditions
provided in this Agreement;

     WHEREAS, the Board recognizes that, as is the case with many corporations,
there exists the possibility of a change of control of the Company, and that
such possibility, and the uncertainty and questions which it may raise, may
result in the distraction of key management personnel to the detriment of the
Company and its affiliates and shareholders, and the Board has determined that
appropriate steps should be taken as set forth in this Agreement to reinforce
and encourage the Executive's continued attention and dedication of his assigned
duties without distraction in the face of potentially disturbing circumstances
arising from the possibility of a change of control;

     NOW, THEREFORE, in consideration of the mutual covenants contained in this
Agreement, the parties agree as follows:

                                   ARTICLE I

                                  DEFINITIONS

the Executive has not substantially performed his duties, and a reasonable
period of opportunity for such
<PAGE>
 
substantial performance is provided, or (B) the willful engaging by the
Executive in illegal misconduct materially and demonstrably injurious to the
Company.  For purposes of this paragraph, no act, or failure to act, on the
Executive's  part shall be considered "willful" unless done, or omitted to be
done, by the Executive not in good faith and without reasonable belief that his
action or omission was in the best interest of the Company. Any act, or failure
to act, based upon authority given pursuant to a resolution duly adopted by the
Board or based upon the advice of counsel for the Company shall be conclusively
presumed to be done, or omitted to be done, by the Executive in good faith and
in the best interest of the Company.  Notwithstanding the foregoing, the
Executive shall not be deemed to have been terminated for Cause unless and until
there shall have been delivered to the Executive a copy of a resolution duly
adopted by the affirmative vote of not less than three-quarters of the entire
membership of the Board, excluding the Executive, at a meeting of the Board
called and held for that purpose (after reasonable notice to the Executive and
an opportunity for the Executive, together with his counsel, to be heard before
the Board), finding that in the good faith opinion of the Board the Executive

Board.

     1.7  "CONFLICT OF INTEREST" means a condition where the loyalty of the

interest of the Company.

     1.8  "DISABILITY" means the Executive's incapacity resulting from injury or
illness, whether mental or physical, which prevents the Executive from

the condition is to be determined by an independent physician selected by mutual
agreement of the Company and the Executive.

     decision by the Board to separate the office of Chairman and President
     shall not be
<PAGE>
 
     considered an adverse change as set forth in this Section 1.11(a) as long
     as the Executive remains as the Chief Executive Officer of the Company with
     duties and responsibilities customarily associated with that office;

          (b) a reduction by the Company in the Executive's Minimum Annual
     Salary or in the number of vacation days to which the Executive is entitled
     hereunder;

          (c) the taking of any action by the Company (including the elimination
     of a plan without providing substitutes therefor or the reduction of the
     Executive's awards thereunder) that would diminish or the failure by the
     Company to take any action which would maintain the aggregate projected
     value of the Executive's awards under the Company's bonus or stock option
     or management incentive unit plans in which the Executive participates;

          (d) the taking of any action by the Company that would diminish or the

     purchase or retirement plans in which the Executive participates or as
     otherwise provided in this Agreement;

age (not less than 65 years of age) established by the Board for his retirement
in accordance with the Company's general policy for retirement of executives,
provided that for purposes of the change of control provisions referred to in

executive capacity as Chairman and President, Chief Executive Officer of the
Company.

                                   ARTICLE V

                               EXTENT OF SERVICE

     The Executive is employed on a full time basis. Therefore, during the
period of his employment, except for illness, reasonable vacation periods and
reasonable leaves of absence, the Executive shall devote all of his business
time, attention, skill and efforts to the faithful performance of his duties
under this Agreement. However, the Executive may devote a small but reasonable
amount of time to pursue and monitor personal investments and charitable or
community services and, with the approval of the Board, from time to time, the
Executive may serve or continue to serve on the boards of directors of and hold
any other offices or position in companies or organizations that in the Board's
reasonable judgment will not present any Conflict of Interest with the Company
or any of its Affiliates
<PAGE>
 
or materially affect the performance of the Executive's duties under this
Agreement.

                                   ARTICLE VI

                                  COMPENSATION

     For services rendered by the Executive under this Agreement the Company
agrees to pay and provide to the Executive compensation and benefits
commensurate with his position and experience level within the oil and gas
industry, which compensation and benefits (i) initially shall be as set forth in
this Article VI and (ii) shall not at any time during the term of this Agreement
be less than as set forth in this Article VI.

     6.1 MINIMUM ANNUAL SALARY.  During each calendar year the Company shall pay
the Executive base compensation in equal semi-monthly installments based upon
the minimum annual salary for the Executive of $500,000, subject to annual
review by the Board and which may be increased but not decreased by the Board on
the basis of such review.  The term "Minimum Annual Salary" as used in this
Agreement shall include all increases granted by the Board.

     6.2 CASH INCENTIVE COMPENSATION.  For each calendar year during the term of
this Agreement the Executive shall be entitled to earn a bonus of between 0% and
90% of the Executive's Minimum Annual Salary for such year upon attaining goals
established annually by the Compensation Committee. The goals shall be
established by the Compensation Committee, after consultation with the
Executive, shall be consistent with the Company's standards, and shall be
established to produce a reasonable expectation in the sole judgment of the
Compensation Committee that the Executive will receive a target bonus for each
year equal to 60% of the Executive's Minimum Annual Salary for such year.  Bonus
factors and other provisions related to the bonus for calendar year 1997 (which
will be consistent with the Executive's position in the Company and with other
executives) will be addressed by the Compensation Committee at its meeting on
February 11, 1997.  The Cash Incentive Compensation earned by the Executive for
any calendar year to the extent not deferred pursuant to Section 6.3, will be
paid to the Executive within 90 days following the end of such calendar year.

     6.3 DEFERRAL ARRANGEMENT.  The Executive will be permitted to defer some or
all of the Cash Incentive Compensation and up to 50% of the Minimum Annual
Salary under the ENSERCH Corporation Deferred Compensation Plan (or comparable
plan of the Company), the terms of which have been provided to the Executive.

     6.4 STOCK OPTIONS.  On or promptly after the Effective Date, the Company
shall grant to the Executive an initial signing bonus award of Stock Options to
acquire 1,000,000 shares of the common stock of the Company with an exercise
price based on the average of the high and low prices on the date of grant and
granted as follows:  An option for 500,000 of the shares will be granted by the
Compensation Committee pursuant to the Stock Incentive Plan and shall be
conditioned upon the execution by the Executive of a stock option agreement
substantially in the form as attached hereto as Exhibit A, and an option with
substantially identical terms for the remaining 500,000 shares will be granted
by the Board by special award and shall be conditioned upon the execution by the
Executive of a stock
<PAGE>
 
option agreement substantially in the form as attached hereto as Exhibit B. Not
later than sixty (60) days following each anniversary of the Effective Date
during the term of this Agreement (provided the Executive continues to be
employed by the Company), the Company shall grant to the Executive a Stock
Option to acquire a number of additional shares of the common stock of the
Company with the grant in 1998 to be calculated as follows:  at least the number
derived from dividing three (3) times the Executive's Minimum Annual Salary by
the fair market value on the last trading date preceding the day that the
Compensation Committee or Board takes action to grant the Option. Grants in
subsequent years shall be made in an amount equal to 115% of the Executive's
Minimum Annual Salary, in accordance with a valuation methodology selected by
the Compensation Committee, after consultation with the Executive and which
appropriately aligns the compensation that the Executive may receive through
stock price growth with the value received by shareholders from the Company's
performance.  The exercise price per share under such option shall be the fair
market value of the stock as of the date of the grant of such option.  The
Options granted to the Executive during the term of this Agreement beyond the
initial grant shall be Non-Qualified Stock Options and shall be pursuant to, and
conditioned upon the execution by the Executive of, stock option agreements with
terms and conditions consistent with those between the Company's other senior
executives and the Company and substantially in the form as attached hereto as
Exhibit C.  No Stock Options shall be granted subsequent to termination of
employment.  The Company shall use its best efforts to cause a registration
statement on form S-8 (or comparable successor form) covering all shares subject
to Stock Options granted to the Executive to remain effective until sixty (60)
days after the later of exercise or termination of all Stock Options granted to
the Executive.

     6.5 RESTRICTED STOCK BONUSES.  On or promptly after the Effective Date, the
Company shall award to the Executive an initial Restricted Stock Bonus for
100,000 shares of performance-based restricted stock of the Company pursuant to
its Stock Incentive Plan and conditioned upon the execution by the Executive of
a Restricted Stock Agreement substantially in the form attached hereto as
Exhibit D.  Not later than sixty (60) days following each anniversary of the
Effective Date during the term of this Agreement (provided the Executive
continues to be employed by the Company), the Company shall award to the
Executive a Restricted Stock Bonus for additional shares of performance-based
restricted stock of the Company having a value equal to 35% of the Executive's
Minimum Annual Salary (with performance requirements as determined by the
Compensation Committee that may vary from the initial award but that are
consistent with performance requirements for awards of performance-based
restricted stock to other senior executives of the Company).  Such shares shall
be restricted so that no share may be transferred or alienated in any way
(except through passage under will or by the laws of descent and distribution
upon the Executive's death) until the shares are vested, at which time the
restriction will lapse with respect to the vested shares.  Such awards shall be
granted pursuant to, and conditioned upon, execution by the Executive of
restricted stock agreements with terms and conditions consistent with those of
other senior executives of the Company and substantially in the form attached
hereto as Exhibit E.  No Restricted Stock Bonuses shall be granted subsequent to
termination of employment.  The Company shall use its best efforts to cause a
registration statement on form S-8 (or comparable successor form) covering all
shares of restricted stock granted to the Executive as Restricted Stock Bonuses
to remain effective until sixty (60)
<PAGE>
 
days after the lapse of all restrictions on the shares of restricted stock
granted to the Executive as Restricted Stock Bonuses.

     6.6 LONG TERM INCENTIVE AWARDS.  The Executive shall be entitled to
participate in any other long term incentive award program as is approved in the
future by the Compensation Committee.

     6.7 OTHER COMPANY COMPENSATION PROGRAMS.  The Executive shall be entitled
to participate at an appropriate level in all other compensation programs
adopted by the Company.

     6.8 LOAN.  Within 30 days following the date that the Executive (i) makes a
Section 83(b) election with respect to any Restricted Stock Bonus received by
the Executive or (ii) such Restricted Stock Bonus becomes fully vested, upon
request by the Executive the Company will lend the Executive an amount equal to
the estimated federal, state and local tax liability the Executive will incur in
connection with making a Section 83(b) election or becoming fully vested in any
Restricted Stock Bonus.  The loan will be on a full recourse basis and secured
in  accordance with the terms of a security agreement (in a form mutually agreed
upon by the Executive and Company) collateralized with Restricted Stock Bonuses,
Stock Options to acquire Company stock, deferred compensation and other amounts
owing but unpaid by the Company to the Executive.  The loan will bear interest
at the prime rate in effect at that time at the Chase Manhattan Bank or other
comparable bank as approved by the Compensation Committee.

                                  ARTICLE VII

                                FRINGE BENEFITS

with the Company pursuant to this Agreement, with the following fringe benefits
at a level commensurate with his position with the Company:

          (c) four weeks paid vacation yearly; and

          (d) a customary benefit and perquisite package for a senior executive
              in his position, provided however, that such package will include
              at least (i) medical and dental coverage, (ii) disability
              insurance covering 60% of Minimum Annual Salary, (iii) provided
              that the Executive is insurable, life insurance equal to four-
              times Minimum Annual Salary through the initial three-year term of
              this Agreement, reduced to three-times Minimum Annual Salary until
              age 60, and reduced to two-times Minimum Annual Salary thereafter,
              and provided that, when authorized by the Compensation Committee,
              the Company may self-insure such amount that may exceed limits of
              the Company's group life insurance policy, and (iv) an excess
              pension plan providing retirement benefits that the Executive
              would have received under the Company's qualified retirement plans
              taking into account the Executive's Minimum Annual Salary and Cash
<PAGE>
 
          Incentive Compensation (regardless of whether or not the Executive
          elects to defer any such amounts under Section 6.3) but for the
          limitations on compensation and benefits under Sections 415 and
          401(a)(17) of the Internal Revenue Code of 1986 relating to qualified
          plans.

                                  ARTICLE VIII

                               WORKING FACILITIES

     The Company shall furnish the Executive with a private office and a private
secretary and all other assistance and accommodations as are suitable to the
character of the Executive's position with the Company and adequate for the
performance of his duties under this Agreement.

                                   ARTICLE IX

                                    EXPENSES

     (a) The Executive is authorized to incur reasonable expenses for the
promotion of the business of the Company including expenses for entertainment,
travel and other similar items. The Company shall pay or reimburse the Executive
for all reasonable items of expense incurred by the Executive in performing his
obligations under this Agreement.  The Executive must, however, in each case
provide the Company adequate substantiation of the expense that has been
incurred by the Executive.

     (b) The Executive shall be provided temporary living and commuting expenses
for six months following the Effective Date.

     (c) In addition to the Company's employee relocation assistance program
which is hereby extended to the Executive, the Company will pay to the Executive
$10,000 to use at his discretion to offset costs associated with the acquisition
of a new home (such as loan origination fees, points, etc.).

     with Good Reason during the initial three-year term of this Agreement, the
     Company shall pay the Executive, within 30 days, a cash sum equal to his
     then Minimum Annual Salary times the number of years (including portions
     thereof) remaining in the initial three-year term of this Agreement, plus
     earned but unpaid Cash Incentive Compensation for the previous year, if
     any, plus the Cash Incentive Compensation that would have accrued to the
     Executive (calculated at the target level of 60 % of the Executive's
     Minimum Annual Salary immediately prior to termination) through the number
     of years (including portions thereof) remaining in the initial three-year
     term of this Agreement; provided, however, that in no event shall the
     Executive be paid less than his Minimum Annual Salary times one, plus the

Disability, the Company shall pay the Executive his then Minimum Annual Salary
for one year from the date of his Disability.  In addition, the Executive shall
be entitled to receive pay for vested but unused vacation on the date of

     10.6 TERMINATION FOR DEATH.  If the Executive dies while in the employ of
the Company, the Company shall pay and provide to the Executive's estate the

entitled to the benefits provided herein and in the Change in Control Agreement,
provided that in the event the terms of this Agreement and the Change in Control
Agreement provide for the same type of benefit or payment based on the same
operative event or facts then the Executive shall be entitled to the higher
benefit or payment under the agreements but not duplicate benefits or payments;
it being specifically agreed that if the Change in Control and the qualifying
termination of employment occurs prior to the end of the initial three-year term
of this Agreement, the Executive will be entitled to the greater of the payments
of salary under this Agreement for the remainder of such initial three-year term
or the payment of three (3) times the Executive's salary under Section 4(iii)(c)
of the Change in Control Agreement.

     10.8 RETIREMENT.  Upon Retirement, the Company shall pay the Executive his

              perform this Agreement in the same manner and to the same extent
