ITEMS 1. AND 2. BUSINESS AND PROPERTIES
 
Introduction
 
     El Paso Natural Gas Company, incorporated in Delaware in 1928, owns and
operates one of the nation's largest field and mainline natural gas transmission
systems, connecting natural gas supply regions in New Mexico, Texas, Oklahoma
and Colorado to markets in California, Nevada, Arizona, New Mexico, Texas and
northern Mexico. As used herein, "Company" refers to El Paso Natural Gas Company
and its subsidiaries and "EPG" refers to El Paso Natural Gas Company, unless the
context otherwise requires.
 
     At December 31, 1991, EPG was a wholly owned subsidiary of Burlington
Resources Inc. ("BR"). In March 1992, EPG completed an initial public offering
of approximately 15 percent of its common stock in the form of newly issued
shares (the "Offering"). On June 30, 1992, BR distributed all of EPG's common
shares it held to BR shareholders, the effect of which was to place all of EPG's
common stock in public ownership.
 
     El Paso Gas Marketing Company ("EPGM") was incorporated in October 1992 as
a wholly owned subsidiary of EPG. EPGM commenced operations on November 1, 1992,
for the purpose of conducting all of EPG's new gas marketing business, while
also acting as EPG's agent in winding down its remaining role as a natural gas
merchant.
 
     On June 1, 1993, the Company acquired from a wholly owned subsidiary of
Enron Corp., that subsidiary's 50 percent interest in Mojave Pipeline Company
("MPC"), a general partnership. This acquisition gives the Company 100 percent
ownership of MPC. MPC is a general partnership formed pursuant to the Uniform
Partnership Act of the State of Texas. MPC was formed for the construction,
ownership and operation of a federally regulated interstate natural gas pipeline
to serve the enhanced oil recovery operations and associated cogeneration
projects in the heavy oil fields in central California.
 
Regulatory Environment
 
     EPG's and MPC's pipeline facilities, services and rates are regulated by
the Federal Energy Regulatory Commission ("FERC") in accordance with the Natural
Gas Act of 1938 and the Natural Gas Policy Act of 1978. Prior to the mid-1980s,
EPG, as was the case with virtually all other interstate pipelines, was engaged
primarily in the business of purchasing gas from producers at the wellhead and
reselling such gas to local distribution companies, such as Southern California
Gas Company ("SoCal") and Pacific Gas & Electric Company ("PG&E"), for resale to
retail customers and to large industrial and electric generation concerns for
their own consumption. During this period, almost all of the gas that moved
through EPG's system was gas that EPG purchased for resale to its customers
("sales service"). Gas that EPG transported for others ("transportation
service") constituted a very small portion of EPG's total throughput.
 
     Since 1984, the natural gas transmission industry has undergone a major
transformation in response to sweeping changes in market conditions and
regulatory policies. These developments have resulted in: (i) the emergence of a
nationwide spot market for natural gas and increasing competition in natural gas
markets; (ii) a restructuring of the contractual relationships between pipelines
and their traditional customers resulting in an increasing displacement of sales
service by transportation service; and (iii) the renegotiation of gas purchase
contracts between pipelines and producers to reduce purchase obligations, reform
pricing provisions and settle take-or-pay claims.
 
     Beginning in April 1992, FERC issued a series of orders (the "Restructuring
Rules") directing a number of significant changes to the structure of the
services provided by interstate natural gas pipelines. The Restructuring Rules
are intended principally to assure "comparability" (i.e., that pipeline and
non-pipeline gas merchants are placed on an equal footing in competing for
sales), to provide a mechanism for the allocation of pipeline capacity and to
eliminate competitive distortions arising from rate design differences between
United States and Canadian pipelines. Under the Restructuring Rules' rate
design, all fixed pipeline costs (including return on equity and related income
taxes) are recovered through reservation charges which do not vary with actual
throughput. Under the previously required rate design, return on equity and
related taxes were excluded
 
                                        1
<PAGE>   4
 
from reservation charges but were recovered along with variable costs through
volumetric rates, which were rates paid for actual volumes transported on the
pipeline. Generally, under the Restructuring Rules' rate design volumetric rates
are considerably lower than under the previously required rate design, and
pipeline earnings are less sensitive to variations in actual throughput.
 
Components of Consolidated Revenues
 
     The following table sets forth the components of the Company's consolidated
revenues:

(a) Reservation revenue relates to the charge for firm transportation service
    or, prior to September 1991, firm sales service.
 
(b) Included in "All other" are revenues generated from gas gathering services
    on the field transmission systems.
 
     In 1993, natural gas deliveries to SoCal, PG&E and Southwest Gas
Corporation accounted for 26 percent, 19 percent and 10 percent, respectively,
of the Company's revenues. No other customer accounted for 10 percent or more of
the Company's consolidated revenues. The Company's revenues for volumes
transported to the Mexico border represented less than one percent of the
Company's operating revenues for each of 1993, 1992 and 1991.
 
EL PASO NATURAL GAS COMPANY
 
General
 
     EPG is directly connected to three of the nation's most prolific gas
producing areas -- the San Juan, Permian and Anadarko Basins. During 1993, EPG
delivered 1.3 trillion cubic feet ("Tcf") of natural gas, accounting for
approximately seven percent of estimated total 1993 United States consumption.
 
     EPG's system consists of approximately 17,000 miles of pipeline with 77
mainline compressor stations having an aggregate installed horsepower of
approximately 1.1 million. The system's present natural gas delivery capacity to
California and East-of-California markets, as discussed below, is approximately
4.6 billion cubic feet per day ("Bcf/d").
 
     EPG's present capacity to deliver natural gas to California, the second
largest natural gas market in the United States, is approximately 3.3 Bcf/d.
EPG's system currently provides 48 percent of the total interstate pipeline
capacity serving the state. In 1993, EPG delivered approximately 43 percent of
all the natural gas consumed in California.
 
     EPG is the principal interstate natural gas transmission system serving
Arizona, including the cities of Phoenix and Tucson; southern Nevada, including
Las Vegas; New Mexico; and El Paso, Texas. EPG's East-of-California market also
includes deliveries to the cities of Ciudad Juarez, Cananea and Hermosillo, in
northern Mexico, and the Samalayuca Power Plant outside of Ciudad Juarez. EPG's
delivery capacity to these East-of-California markets is approximately 1.3
Bcf/d.
 
     Since the late 1980s, in response to changing market demands, EPG has been
delivering substantial quantities of gas from the San Juan Basin to
interconnecting pipelines for ultimate redelivery to off-system markets on the
Gulf Coast and in the Midwest. This alternate routing has been effectuated by
exchanges ("back-hauls") between EPG and an interconnecting pipeline. Volumes of
gas which the interconnecting pipeline is otherwise scheduled to deliver to EPG
for redelivery in EPG's traditional markets are traded for
 
                                        2
<PAGE>   5
 
like volumes of San Juan gas which EPG has accepted for delivery to the
interconnecting pipeline. With EPG's 1992 completion of a system modification
which made an existing pipeline segment linking the San Juan Basin and Permian
Basin bi-directional, total delivery capacity to off-system markets east of
EPG's system can be as high as 1.1 Bcf/d depending on the level of demand
elsewhere on EPG's system. Although their contributions to revenues and earnings
are still comparatively small, off-system deliveries represent a strategic
long-term diversification of EPG's market base. Presently, EPG is the largest
provider of access to off-system markets for San Juan Basin producers.
 
     Set forth below is a breakdown of EPG's natural gas deliveries by market
area for the periods indicated (volumes shown are in million cubic feet per day
("MMcf/d")):

Gathering and Production Area Facilities
 
     On January 14, 1994, EPG filed an application with FERC seeking an order
which would terminate, effective January 1, 1996, certificates applicable to
certain gathering and production area facilities owned by EPG on the basis that
such facilities are not subject to FERC jurisdiction.
 
     EPG intends, effective January 1, 1996, to transfer all of its
nonjurisdictional gathering and production area facilities to a wholly owned
subsidiary of EPG. Such facilities are used for gathering and other
nonjurisdictional functions and are an inherent part of EPG's current gathering
operations. The facilities to be transferred consist of approximately 6,700
miles of various sized pipelines, compressors with horsepower of 40,600 and
various treating and processing plants. These nonjurisdictional facilities,
together with the facilities included in the January 14, 1994 FERC application,
constitute all of EPG's gathering and production area facilities.
 
Rate Matters
 
     On July 1, 1991, EPG filed for FERC approval of new system rates and placed
the proposed new rates into effect on January 1, 1992, subject to refund. On
July 31, 1992, EPG again filed for new system rates to recover increased costs
and return on rate base associated with EPG's expansion and modernization
projects. These rates became effective on February 1, 1993, subject to refund.
In the July 1992 filing, EPG's rate base increased from $752 million to
approximately $1.2 billion. EPG made its compliance filing on December 31, 1992,
in accordance with the Restructuring Rules.
 
     In January 1993, EPG, certain of its customers and FERC staff reached a
settlement agreement which led to the resolution of the above mentioned rate and
restructuring proceedings. The settlement agreement was filed in January 1993 to
supersede EPG's December 31, 1992 compliance filing. As required by FERC order,
EPG filed revised rates on September 14, 1993, which implemented the settlement
agreement effective October 1, 1993.
 
     The settlement agreement provides for the accelerated recovery of a
substantial portion of EPG's investment in its underground storage facility.
This is being recovered by a demand charge mechanism over the period from
October 1, 1993 through December 31, 1996. The amount recovered through December
31, 1993 was $19 million. The outstanding balance was $37 million at December
31, 1993. The settlement agreement also established new depreciation rates for
certain of EPG's facilities effective January 1, 1992.

Producer Settlement and Cost Recovery
 
     Since 1987, EPG has incurred approximately $1.5 billion in buy-out and
buy-down costs to resolve past and future take-or-pay exposure, to terminate and
reform gas purchase contracts, to amend pricing and take provisions of gas
purchase contracts and to settle related litigation. Pursuant to FERC orders,
EPG has absorbed approximately 25 percent of such costs and is entitled to
recover the balance. Such recovery is made through direct billing of EPG's
customers of 25 percent of the $1.5 billion and through a surcharge on all
throughput volumes for the remaining 50 percent of such amount. EPG has filed to
recover $1.1 billion of its buy-out and buy-down costs under FERC cost recovery
procedures. The collection period for the direct bill portion of the take-or-pay
buy-out and buy-down costs extends through May 1994. The collection period for
the volumetric surcharge portion of such costs extends through March 1996.
Through December 31, 1993, EPG had recovered approximately $1.0 billion; of that
recovery, $361 million was collected by direct bill and $682 million by
volumetric surcharge. EPG has established a reserve for that portion of the
volumetric surcharge receivables balance which is unlikely to be collected over
the period through March 1996, based on current throughput projections. The
balance of this reserve was $19 million at December 31, 1993.
 
     Under FERC procedures, take-or-pay cost recovery filings may be challenged
by pipeline customers on prudence and certain other grounds. In October 1992,
FERC approved an order, subject to rehearing, resolving all but one of the
outstanding issues regarding EPG's take-or-pay proceedings. The remaining issue
involves the claim by several customers that EPG has sought to recover an
excessive amount for the value of certain production properties which were
transferred to a producer as part of a 1989 take-or-pay settlement. On March 8,
1993, an initial decision from the presiding Administrative Law Judge ("ALJ")
was rendered which, if adopted without changes by FERC, would require EPG to
refund to or forgo collection from its customers of up to $30 million, plus
interest. Exceptions to this initial decision were filed with FERC by both
parties on April 7, 1993. On April 27, 1993, briefs opposing exceptions were
filed by the same parties as well as by FERC staff. EPG has established adequate
reserves for this issue and does not believe that the ultimate outcome will have
a materially adverse effect on the Company's financial condition or results of
operations.
 
     On January 14, 1992, EPG completed a sale of substantially all of its
remaining take-or-pay buy-out and buy-down receivables. See "Management's
Discussion and Analysis of Financial Condition and Results of
Operations -- Financial Condition and Liquidity -- Take-or-pay Settlements."
 
Gas Supply
 
     During 1993, approximately 270 wells first delivered gas into EPG's system.
The total gas well availability physically connected to EPG's gathering systems
was approximately 1.5 Bcf/d at year-end 1993. During 1993, EPG received an
average of 1.8 Bcf/d from physical points interconnected with other pipelines or
from receipt points pursuant to transportation and exchange agreements. EPG's
maximum mainline system inlet capacity is 4.7 Bcf/d.
 
System Expansions
 
     In April 1992, EPG completed the addition of 400 MMcf/d of mainline
capacity from the San Juan Basin to the California border. This addition is
committed pursuant to firm long-term contracts with fixed reservation charges.
EPG also completed a system modification making an existing pipeline segment
linking the San Juan Basin and Permian Basin bi-directional to allow for the
eastward movement of up to 435 MMcf/d, of which 255 MMcf/d is committed pursuant
to firm contracts. The total cost of the expansion and modification projects was
approximately $250 million.
 
     On July 7, 1992, EPG filed an application with FERC, which was amended on
November 27, 1992, to expand the delivery capacity of its system in the vicinity
of Yuma, Arizona and, through an extension of its system south to San Luis Rio
Colorado, Sonora, Mexico, to serve northern Mexican markets. The proposed
expansion would provide shippers the opportunity to deliver natural gas to
Mexican markets in northern Baja California via new pipeline capacity of 348
MMcf/d. This project is expected to cost approximately
 
                                        4
<PAGE>   7
 
$71 million and will be financed through internally generated funds or through
short-term borrowings. On November 29, 1993, FERC issued an order which approved
the siting, construction and operation of facilities necessary for a border
crossing facility in Yuma, Arizona which would connect the proposed extension
with pipeline facilities in Mexico. The order also made a preliminary
determination on environmental issues. FERC is deferring action on the remainder
of the July 7, 1992 filing until EPG demonstrates that it has long-term executed
contracts or binding precedent agreements for a substantial amount of the firm
capacity of the proposed facilities.
 
     EPG is a member of a five-company consortium that plans to build the
proposed Samalayuca II Power Plant near Ciudad Juarez, Mexico. On December 17,
1992, an award for construction was granted to the consortium by Comision
Federal de Electricidad, the Mexican government-owned utility. On March 16,
1993, EPG filed an application with FERC to expand its system in order to
provide natural gas service to the proposed Samalayuca II Power Plant and to an
existing power plant in the same location. The proposed expansion would provide
an additional 300 MMcf/d of capacity at a cost of approximately $57 million and
will be financed through internally generated funds or through short-term
borrowings. In the November 29, 1993 order, FERC also approved the proposed
border crossing facility south of Clint, Texas which would connect EPG's
facilities with facilities in Mexico. FERC is deferring action on the remainder
of the March 16, 1993 filing until EPG demonstrates that it has long-term
executed contracts or binding precedent agreements for a substantial amount of
the firm capacity of the proposed facilities.
 
     On December 29, 1993, PG&E, SoCal and the California Public Utilities
Commission ("CPUC") jointly filed a motion with FERC seeking clarification or
rehearing of the November 29, 1993 FERC order for both the Yuma, Arizona and the
Samalayuca II Power Plant projects discussed above.
 
Master Separation Agreement
 
     In contemplation of the separation of EPG from all other BR-controlled
entities, EPG, BR and Meridian Oil Holding Inc. ("Meridian"), a wholly owned
subsidiary of BR, engaged in a comprehensive review of business and contractual
relationships necessary and appropriate for the efficient and effective business
operations and long-term planning of both EPG and Meridian. These business
relationships are addressed in detail in a Master Separation Agreement (the
"Separation Agreement"), dated January 15, 1992, and related operative
agreements provided for therein.
 
     The Separation Agreement and related operative agreements provide for
specific and detailed operating agreements, transportation service agreements,
natural gas liquids marketing agreements and gas supply arrangements between EPG
and Meridian, including Meridian's affiliates, which are appropriate to
facilitate stand-alone operations by the companies. The Separation Agreement
also provides to Meridian certain defined preferential purchase rights,
extending for a period of five years, with respect to EPG's San Juan Basin
gathering system which is of significant importance to the business activities
of both EPG and Meridian. In addition, the Separation Agreement specifically
addresses matters relating to the allocation of pension fund assets and
liabilities, tax sharing and allocation, right-of-way access and usage, and
indemnification rights and obligations, among other things. The contractual and
business arrangements, insofar as they relate to FERC jurisdictional service
provided by EPG to Meridian, are representative of arrangements with respect to
FERC jurisdictional services which EPG can offer to non-affiliated companies
situated similarly to Meridian. In instances where Meridian may have a right to
acquire certain assets from EPG under the Separation Agreement, including any
acquisition of the San Juan Basin gathering system, Meridian would pay EPG the
fair market value for such assets. The foregoing discussion is only a summary of
certain provisions of the Separation Agreement and the related operative
agreements provided for therein and is qualified in its entirety by reference to
the Separation Agreement and such operative agreements.
 
MOJAVE PIPELINE COMPANY
 
General
 
     In 1990, FERC issued orders authorizing MPC to construct and operate its
pipeline facilities, which commenced operations on March 1, 1992. MPC's system
consists of approximately 400 miles of pipeline with
 
                                        5
<PAGE>   8
 
one mainline compressor station. The system's present natural gas delivery
capacity is 400 MMcf/d. MPC's only business is natural gas transportation.
 
     Set forth below are MPC's natural gas deliveries for the periods indicated:

     Included in throughput for May 1993 through December 1993 are 19 MMcf/d of
intercompany transportation volumes. Only revenues associated with the
throughput for May 1993 through December 1993, other than intercompany
throughput, are included in the Company's consolidated results of operations.
Revenues related to throughput associated with the Company's previously owned 50
percent equity interest in MPC are included in other-net in the accompanying
Consolidated Statement of Income.
 
     Mojave Pipeline Operating Company ("MPOC"), a wholly owned subsidiary of
MPC, is a Texas corporation. MPOC serves as MPC's agent in the management of the
pipeline facilities and the design and construction of future pipeline
expansions.
 
Rate Matters
 
     Pursuant to the Restructuring Rules, MPC filed its restructuring plan on
November 3, 1992. On March 2, 1993, FERC issued an order essentially approving
MPC's compliance filing, subject to changes, which were made in an amended
restructuring plan on March 29, 1993. Several of MPC's customers filed protests
and requests for rehearing of the March 2, 1993 FERC order. The rehearing
requests were denied, and FERC approved the amended restructuring plan on July
9, 1993, with an effective date of August 1, 1993. On October 15, 1993, FERC
issued an order which denied requests for rehearing of the July 9, 1993 order.
Several of MPC's customers have filed petitions for review of the March 2, 1993,
July 9, 1993, and October 15, 1993 orders with the United States Court of
Appeals, which are currently pending.
 
     The primary issues on appeal pertain to FERC's requirement that MPC's rates
for firm transportation service be based upon Straight Fixed Variable ("SFV")
rate design rather than Modified Fixed Variable ("MFV") rate design. The
application of SFV rates requires MPC's existing firm shippers to pay a higher
proportion of their total transportation rate in the reservation component of
the rate, and this increases aggregate transportation charges for low load
factor shippers. Such shippers have contended that FERC's application of SFV
rate design to MPC unlawfully abrogates the rate provisions of MPC's service
agreements and constitutes an unlawful rate increase. MPC believes the United
States Court of Appeals will uphold SFV rates as applied to MPC.
 
Gas Supply
 
     At certain times during 1993, MPC received as much as 360 MMcf/d at
physical points of interconnection with other pipelines pursuant to
transportation agreements. MPC's maximum mainline system inlet capacity is 400
MMcf/d.
 
System Expansion
 
     On March 17, 1993, MPC filed an application, which was amended on November
8, 1993, for a certificate of public convenience and necessity to build and
operate a 475 MMcf/d expansion of its existing system. The proposed expansion
will extend from MPC's existing east lateral located near Bakersfield,
California approximately 352 miles northward to the vicinity of Sacramento and
the East Bay area near San Francisco. The expansion will also include 56 miles
of looping of the existing pipeline along with 207 miles of laterals. The
estimated cost of the entire system is $467 million which is expected to be
funded primarily through project financing. MPC expects to receive its FERC
certificate in early 1994 and put the expansion into service in January 1996.
 
                                        6
<PAGE>   9
 
     On December 16, 1993, FERC held a public conference to examine a
jurisdictional question raised by the CPUC and PG&E regarding MPC's system
expansion. The primary issue is whether FERC or CPUC should have jurisdiction
over the proposed expansion. Written comments were filed by interested parties
on January 10, 1994, with a final decision by FERC expected in early 1994.
 
EL PASO GAS MARKETING COMPANY
 
     EPGM buys and sells natural gas under both short-term and long-term
market-sensitive transactions, capitalizing on the strength of EPG's traditional
market areas, as well as the new markets developing in the southwestern United
States and northern Mexico.
 
     As EPG's agent, EPGM is responsible for managing EPG's certificated sales
arrangements with West Coast and Southwestern utilities and municipalities. EPGM
is also responsible for managing EPG's remaining long-term gas purchase
agreements which will decline to a level of 58 MMcf/d in 1994 and continue to
decline in subsequent years. Based on the contract pricing provisions of these
remaining gas supply commitments, EPGM expects that it will experience no
difficulty in continuing to contract for the sale of such gas.
 
OTHER MATTERS
 
  Competition
 
     Currently, EPG faces competition from other companies which transport
natural gas to the California market. Competition generally occurs on the basis
of price, quality and reliability of service.
 
     The total present interstate pipeline capacity for delivering natural gas
to the California border is approximately 6.9 Bcf/d. In addition to EPG, three
other major interstate pipelines presently deliver natural gas to California.
Transwestern Pipeline Company ("Transwestern") has the capacity to deliver
approximately 1.1 Bcf/d from Permian, Anadarko and San Juan Basin supply
sources; Pacific Gas Transmission Company ("PGT") has the capacity to deliver
about 1.8 Bcf/d of Canadian gas; and Kern River Gas Transmission ("Kern River")
has the capacity to deliver approximately 700 MMcf/d from Rocky Mountain supply
sources. PGT completed a 755 MMcf/d expansion of its California capacity on
November 1, 1993. In 1992, Kern River held an open season to determine interest
in expanding capacity to California by 200 MMcf/d; however, no planned
expansions have since been announced.
 
     Demand for natural gas in the California market is projected to be less
than capacity for some time to come. EPG maintains a strong competitive position
in the market by virtue of the fact that its pipeline is, and expects to remain,
the lowest-cost transporter of natural gas to California and the principal means
of moving gas from the San Juan Basin to the California border. EPG's pipeline
capacity to California is fully subscribed under long-term contracts which
provide for the payment of fixed reservation charges.
 
     EPG's largest single contract for interstate capacity to California is its
1,450 MMcf/d contract with SoCal, which has a primary term ending August 31,
2006. In 1992, SoCal relinquished 300 MMcf/d pursuant to this contract (out of
an original contract demand quantity of 1,750 MMcf/d), all of which was
subsequently subscribed by new firm shippers under long-term contracts. Pursuant
to this contract, SoCal has the option to relinquish an additional 300 MMcf/d of
capacity during the first quarter of 1996. PG&E has a contract for 1,140 MMcf/d
of firm capacity rights on EPG's system. This contract has a primary term ending
December 31, 1997. CPUC has directed PG&E to maintain 600 MMcf/d of capacity on
EPG's system to service PG&E's core and core subscription service customers. EPG
expects to offset potential future reductions in capacity commitments through
new contracts with various natural gas users in California which are now served
indirectly through SoCal and PG&E, as well as through the development of
additional East-of-California and northern Mexico markets.
 
     In general, natural gas faces varying degrees of competition from
electricity, coal and oil. Competitive pressure from alternative fuels is less
prevalent in EPG's market area due to strict environmental regulations in
California.

  Environmental Compliance
 
     Accruals for environmental compliance costs are established when
environmental assessments and/or remediation are probable, and when costs can be
reasonably estimated. As of December 31, 1993, EPG had a reserve of $38 million
for the following environmental contingencies with income statement impact:
 
     1 -- EPG has been conducting remediation of polychlorinated biphenyl
     ("PCB") contamination at its facilities. The majority of the required PCB
     remediation has been completed. Future PCB remediation costs are estimated
     to range between $8 million and $11 million over the next five years.
 
     2 -- EPG executed an Administrative Order on Consent with the United States
     Environmental Protection Agency ("EPA") on June 25, 1993 to conduct a
     Remedial Investigation/Feasibility Study ("RI/FS") for a Burlington
     Industries, Inc. ("BI") site located in Statesville, North Carolina, that
     has been identified for cleanup. BI and EPG have entered into an agreement
     to jointly fund the RI/FS for the site. EPG's share of the potential
     remediation costs is estimated to be between $17 million and $20 million
     over a 30 year period.
 
     3 -- On November 2, 1993, in accordance with an EPA order, EPG and Atlantic
     Richfield Company ("ARCO") submitted work plans for remediation of the
     subsurface at the Prewitt Refinery in McKinley County, New Mexico. EPG and
     ARCO have a cost sharing agreement to each pay one-half of any remediation
     costs at this site. EPG's share of the remediation costs is estimated to be
     between $10 million and $20 million over a 30 year period.
 
     4 -- EPG is involved in other environmental assessment and remediation
     activities which include two additional Comprehensive Environmental
     Response, Compensation and Liability Act of 1980 ("CERCLA") sites 
     (Fountain Inn, South Carolina and Odessa, Texas) and one state Superfund
     site (Etowah, Tennessee). The amount reserved as of December 31, 1993 will
     cover these and other small environmental assessments and other    
     remediation projects.
 
EPG also has potential expenditures, of a capital nature, for the following
environmental projects:
 
     1 -- EPG has analyzed the Clean Air Act Amendments of 1990 ("CAAA"), and
     believes that these rules will impact the Company's operations primarily in
     the following areas: (i) potential required reductions in the emissions of
     nitrogen oxides ("NOx") in non-attainment areas; (ii) the requirement for
     air emissions permitting of existing facilities; and (iii) enhanced
     monitoring of air emissions. The Company anticipates capitalizing the
     equipment costs associated with complying with CAAA and estimates that
     approximately $5 million to $27 million will be spent during the 1995
     through 1997 time frame. However, EPA's proposed enhanced monitoring rules,
     when finalized, could potentially impose greater costs to the Company.
 
     2 -- EPG has been conducting remediation of mercury contamination at
     certain facilities and is replacing mercury containing meters with dry flow
     devices. The remaining remediation costs are estimated to be between $8
     million and $12 million, most of which will be incurred over the next two
     years. EPG will close and retire about 5,400 earthen siphon/dehydration
     pits in the San Juan Basin as recently required by certain environmental
     regulations. EPG estimates costs of approximately $17 million to $25
     million to retire these pits over the next two years. The mercury
     remediation and pit closure costs, which are associated with the retirement
     of equipment, will be recorded as adjustments to accumulated depreciation,
     as required by regulatory accounting.
 
     On December 21, 1993, EPA issued EPG a Notice of Liability for the Colorado
School of Mines Research Institute ("CSMRI") site in Golden, Colorado. Because
EPA has not yet determined the volume of hazardous substances sent to the site
by all parties, there is no way to estimate EPG's potential share of remediation
costs. However, based on the volumes EPA presently lists as contributed by EPG
and other potentially responsible parties, it appears that EPG is a minor
contributor.
 
     It is possible that new information or future developments could require
the Company to reassess its potential exposure related to environmental matters.
As such information or developments occur, contingency amounts will be adjusted
accordingly.

ITEM 3.  LEGAL PROCEEDINGS
 
     In El Paso Natural Gas Company and Meridian Oil Gathering Inc. v. Amoco
Production Company, filed in Delaware Chancery Court on May 8, 1991, Amoco
Production Company ("Amoco") alleged breaches by EPG and a then affiliated
company, Meridian Oil Gathering Inc. ("MOGI"), of certain gas purchase,
gathering and transportation agreements pertaining to natural gas produced by
Amoco in the San Juan Basin. Amoco alleged breach of "favored nations"
contractual provisions regarding services to be performed by EPG, including
those relating to transportation capacity and rates, and has sought a court
order requiring specific performance by EPG and MOGI with respect to future
transportation services and an award of monetary damages of an undetermined
amount for alleged past breaches of contract. On March 4, 1992, the Court issued
a Memorandum Opinion which, among other things, denied Amoco's motion for
partial summary judgment and concluded that the Amoco contracts at issue do not
contain the general "favored nations" rights claimed by Amoco. The court further
concluded that EPG's and MOGI's motions for summary judgment, seeking dismissal
of Amoco's counterclaim against MOGI, should be granted. Conoco Inc. ("Conoco")
asserted claims similar to Amoco's original claims, involving lesser quantities
of gas, in a separate Delaware Chancery Court proceeding filed on December 30,
1991, Conoco Inc. v. El Paso Natural Gas Company. In August 1992, the Amoco and
Conoco cases were consolidated, MOGI was dismissed as a party, and Amoco and
Conoco filed amended pleadings to restate their claims in lights of the court's
March 4, 1992 ruling. EPG and Conoco concluded a settlement agreement which
resulted in dismissal of the Conoco claims. Trial of the Amoco claims concluded
on July 15, 1993; however, the court's decision has not yet been issued.
Post-trial briefing and oral arguments concluded in early November 1993, and the
decision of the court is expected in early 1994. Management does not expect the
outcome of this matter to have a materially adverse effect on the Company's
financial condition.
 
     The Company is a named defendant in numerous lawsuits and a named party in
numerous governmental proceedings arising in the ordinary course of business.
While the outcome of such lawsuits or other proceedings against the Company
cannot be predicted with certainty, management does not expect these matters to
have a materially adverse effect on the Company's financial condition.
 
ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
 
     During the fourth quarter of 1993, no matters were submitted to a vote of
security holders.

ITEM 5.  MARKET FOR REGISTRANT'S COMMON EQUITY
         AND RELATED STOCKHOLDER MATTERS
 
     All outstanding common stock of EPG was owned by BR until March 1992. In
March 1992, EPG completed the Offering. On June 30, 1992, BR distributed its
31.4 million shares of EPG common stock, which represented approximately 85
percent of EPG's outstanding common stock, to BR shareholders. As a result, BR
no longer retains an ownership interest in EPG.
 
     EPG's common stock is traded on the New York Stock Exchange. As of January
14, 1994 the approximate number of holders of record of common stock was 25,673.
This does not include individual participants on whose behalf a clearing agency
or its nominee holds EPG's common stock.
 
     The following table reflects the high and low sales prices for and cash
dividends declared on EPG's common stock based on the daily composite listing of
stock transactions for the New York Stock Exchange.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS
 
FINANCIAL CONDITION AND LIQUIDITY
 
     Cash provided by operating activities was $236 million for 1993 compared
with $334 million for 1992. The decrease from the previous year was primarily
due to proceeds received in 1992 from the sale of the direct bill portion of the
take-or-pay receivables, lower take-or-pay collections in 1993, rate refund
payments resulting from the settlement agreement and costs incurred to repair
flood damaged pipelines (see Other of this section), partially offset by
decreased tax payments in 1993.
 
     Cash provided by continuing operating activities was $334 million for 1992
compared with $249 million for 1991. The increase was primarily due to proceeds
from the sale of the direct bill portion of the take-or-pay receivables, the
1991 net cash payments made in connection with the August 14, 1991 FERC order
(see Rates and Regulatory Matters of this section), the decrease in take-or-pay
expenditures and a decrease in interest payments. The increase was partially
offset by a reduction in volumetric take-or-pay receivable collections and a
decrease in accruals for regulatory issues.
 
Acquisition
 
     On June 1, 1993, the Company acquired from a wholly owned subsidiary of
Enron Corp., that subsidiary's 50 percent interest in MPC, for approximately $40
million in cash, representing the approximate book value of the investment. The
acquisition, which was funded by internally generated cash flow, gives the
Company 100 percent ownership of MPC. The acquisition was accounted for using
the purchase method.
 
     In conjunction with the acquisition, the following liabilities were
assumed:

  Gathering and Production Area Facilities
 
     On January 14, 1994, EPG filed an application with FERC seeking an order
which would terminate, effective January 1, 1996, certificates applicable to
certain gathering and production area facilities owned by EPG on the basis that
such facilities are not subject to FERC jurisdiction.
 
     EPG intends, effective January 1, 1996, to transfer all of its
nonjurisdictional gathering and production area facilities to a wholly owned
subsidiary of EPG. Such facilities are used for gathering and other
nonjurisdictional functions and are an inherent part of EPG's current gathering
operations. The facilities to be transferred consist of approximately 6,700
miles of various sized pipelines, compressors with horsepower of 40,600 and
various treating and processing plants. These nonjurisdictional facilities,
together with the facilities included in the January 14, 1994 FERC application,
constitute all of EPG's gathering and production area facilities.
 
  Rates and Regulatory Matters
 
     On July 1, 1991, EPG filed for FERC approval of new system rates and placed
the proposed new rates into effect on January 1, 1992, subject to refund. On
July 31, 1992, EPG again filed for new system rates to recover increased costs
and return on rate base associated with EPG's expansion and modernization
projects. These rates became effective on February 1, 1993, subject to refund.
In the July 1992 filing, EPG's rate base increased from $752 million to
approximately $1.2 billion. EPG made its compliance filing on December 31, 1992
in accordance with the Restructuring Rules.
 
     In January 1993, EPG, certain of its customers and FERC staff reached a
settlement agreement which led to the resolution of the above mentioned rate and
restructuring proceedings. The settlement agreement was filed in January 1993 to
supersede EPG's December 31, 1992 compliance filing. As required by FERC order,
EPG filed revised rates on September 14, 1993, which implemented the settlement
agreement effective October 1, 1993. Under the settlement agreement, EPG
refunded a total of approximately $56 million, inclusive of interest, in the
fourth quarter of 1993. EPG had provided for these rate refunds as revenues were
collected.
 
     The settlement agreement provides for the accelerated recovery of a
substantial portion of EPG's investment in its underground storage facility.
This is being recovered by a demand charge mechanism over the period from
October 1, 1993 through December 31, 1996. The amount to be recovered was
approximately $56.7 million plus interest accruing beginning February 1, 1993 at
the FERC allowed rate, which approximates the prime rate. The amount recovered
through December 31, 1993 was $19 million. The outstanding balance at December
31, 1993 was $37 million, of which $12 million is included in other current
assets and $25 million is included in other assets in the accompanying
Consolidated Balance Sheet. The settlement agreement also established new
depreciation rates for certain of EPG's facilities effective January 1, 1992.
 
     On August 14, 1991, FERC approved an order resolving all of the issues in
EPG's December 1987 rate case filing and certain other pending matters which
became effective on September 1, 1991. The order provided for: (i) the
establishment of revised rate levels for the period July 1, 1988 through the
effective date of EPG's next rate change, which occurred on January 1, 1992; and
(ii) payment of certain refunds for the
 
                                       14
<PAGE>   17
 
period July 1, 1988 through August 31, 1991. EPG disbursed to its customers $252
million in October 1991 in accordance with the order. The total refund
obligation at September 1, 1991 was $369 million before certain offsets,
including an unbilled portion of the $169 million of recoverable excess gas
costs. The net refund obligation and the remaining balance of the recoverable
excess gas costs, $25 million, were recorded against previously established
accruals.
 
     Pursuant to the Restructuring Rules, MPC filed its restructuring plan on
November 3, 1992. On March 2, 1993, FERC issued an order essentially approving
MPC's compliance filing, subject to changes, which were made in an amended
restructuring plan on March 29, 1993. Several of MPC's customers filed protests
and requests for rehearing of the March 2, 1993 FERC order. The rehearing
requests were denied, and FERC approved the amended restructuring plan on July
9, 1993, with an effective date of August 1, 1993. On October 15, 1993, FERC
issued an order which denied requests for rehearing of the July 9, 1993 order.
Several of MPC's customers have filed petitions for review of the March 2, 1993,
July 9, 1993 and October 15, 1993 orders with the United States Court of Appeals
which are currently pending.
 
     The primary issues on appeal pertain to FERC's requirement that MPC's rates
for firm transportation service be based upon SFV rate design rather than MFV
rate design. The application of SFV rates requires MPC's existing firm shippers
to pay a higher proportion of their total transportation rate in the reservation
component of the rate, and this increases aggregate transportation charges for
low load factor shippers. Such shippers have contended that FERC's application
of SFV rate design to MPC unlawfully abrogates the rate provisions of MPC's
service agreements and constitutes an unlawful rate increase. MPC believes the
United States Court of Appeals will uphold SFV rates as applied to MPC.
 
  Take-or-Pay Settlements
 
     Since 1987, EPG has made, or has committed to make, buy-out and buy-down
payments totaling $1.5 billion to resolve past and future take-or-pay exposure,
to terminate and reform gas purchase contracts, to amend pricing and take
provisions of gas purchase contracts and to settle related litigation. In
certain cases, EPG resolved claims by making recoupable prepayments. At December
31, 1993 and December 31, 1992, the recoupable prepayment balances were $9
million and $19 million, respectively. These payments resolved virtually all the
outstanding producer claims asserted against EPG and terminated or prospectively
reformed substantially all of EPG's remaining gas purchase contracts, with the
result that EPG no longer has any material take-or-pay exposure.
 
     EPG has filed to recover $1.1 billion of its buy-out and buy-down costs
under FERC cost recovery procedures. The collection period for the direct bill
portion of the take-or-pay buy-out and buy-down costs extends through May 1994.
The collection period for the volumetric surcharge portion of such costs extends
through March 1996. Through December 31, 1993, EPG had recovered approximately
$1.0 billion; of that recovery, $361 million was collected by direct bill and
$682 million by volumetric surcharge. EPG has established a reserve for that
portion of the volumetric surcharge receivables balance which is unlikely to be
collected over the period through March 1996, based on current throughput
projections. The balance of this reserve was $19 million at December 31, 1993.
 
     Under FERC procedures, take-or-pay cost recovery filings may be challenged
by pipeline customers on prudence and certain other grounds. In October 1992,
FERC approved an order, subject to rehearing, resolving all but one of the
outstanding issues regarding EPG's take-or-pay proceedings. The remaining issue
involves the claim by several customers that EPG has sought to recover an
excessive amount for the value of certain production properties which were
transferred to a producer as part of a 1989 take-or-pay settlement. On March 8,
1993, an initial decision from the presiding ALJ was rendered which, if adopted
without changes by FERC, would require EPG to refund to or forgo collection from
its customers of up to $30 million, plus interest. Exceptions to this initial
decision were filed with FERC by both parties on April 7, 1993. On April 27,
1993, briefs opposing exceptions were filed by the same parties as well as by
FERC staff. EPG has established adequate reserves for this issue and does not
believe that the ultimate outcome will have a materially adverse effect on the
Company's financial condition or results of operations.

     On January 14, 1992, EPG completed a sale of substantially all of its
remaining take-or-pay buy-out and buy-down receivables. The sale totaled $325
million, including $305 million of cash received at closing, which was used to
repay $300 million of a payable to BR. The receivables sold in this transaction
included $104 million which was recovered through direct bill and $221 million
to be recovered through volumetric surcharge. The volumetric surcharge portion
of the sale has been accounted for as a financing transaction because EPG is
subject to certain recourse provisions related to such receivables. At December
31, 1993 and December 31, 1992, $87 million and $125 million, respectively, of
the volumetric surcharge portion of the receivables sold remained outstanding.
Amounts collected related to the take-or-pay receivables sold are remitted to
the purchasers of the receivables.
 
  Restructuring and Financing Transactions
 
     In February 1992, EPG established a $300 million revolving credit facility
with a group of banks which expires in March 1996. As of December 31, 1993,
there were no borrowings outstanding under this facility. Approximately $1
million of commercial paper was outstanding as of December 31, 1993.
 
     During 1992 and 1991, EPG completed several transactions in preparation for
its separation from BR. Among these transactions was the transfer of the net
assets of El Paso Production Company ("EPPC") and Meridian Oil Hydrocarbons Inc.
("Hydrocarbons"), collectively, the Company's Oil and Gas Operations Segment,
which is reported as discontinued operations.
 
     In December 1991, EPG declared and paid a dividend to BR of $55 million. In
January and February 1992, EPG declared and paid dividends totaling $274 million
to BR. These dividends were paid from the balance owed to EPG under an
intercorporate cash management arrangement.
 
     In March 1992, EPG completed the Offering. The proceeds from the Offering,
net of related costs, totaled approximately $96 million. On June 30, 1992, BR
distributed its 31.4 million shares of EPG's common stock to BR shareholders,
which represented approximately 85 percent of EPG's outstanding common stock. As
a result, BR no longer retains an ownership interest in EPG.
 
     EPG had a Commitment Agreement with BR under which it could borrow up to
$300 million and Loan Agreements for borrowings up to $500 million. At December
31, 1991, outstanding borrowings under the Commitment and Loan Agreements were
$300 million and $325 million, respectively. In January 1992, additional
borrowings of $109 million were made under the Loan Agreements to purchase the
notes and debentures described below.
 
     EPG also undertook certain transactions to establish an appropriate capital
structure for its post-separation operations. In December 1991 and January 1992,
EPG purchased notes and debentures totaling $253 million and $134 million,
respectively. Funds were provided by proceeds from borrowings under the BR Loan
Agreements. In addition, all of the outstanding 9 5/8% debentures were called
for redemption at 106.84 percent of their principal amount. In January 1992, EPG
received net proceeds of $569 million from the issuance of new debt securities.
The proceeds were used for repayment of borrowings under the Loan Agreements
with BR, redemption of debentures and payment of general corporate costs.
 
     EPG repaid its outstanding commercial paper in December 1991 with
borrowings under the Commitment Agreement with BR. The proceeds from the sale of
the take-or-pay receivables, previously discussed herein, were used to repay the
borrowings under the Commitment Agreement with BR.
 
     The Commitment Agreement and the Loan Agreements with BR were terminated
prior to the completion of the Offering.
 
  Competition
 
     Currently, EPG faces competition from other companies which transport
natural gas to the California market. Competition generally occurs on the basis
of price, quality and reliability of service.
 
     The total present interstate pipeline capacity for delivering natural gas
to the California border is approximately 6.9 Bcf/d. In addition to EPG, three
other major interstate pipelines presently deliver natural
 
                                       16
<PAGE>   19
 
gas to California. Transwestern has the capacity to deliver approximately 1.1
Bcf/d from Permian, Anadarko and San Juan Basin supply sources; PGT has the
capacity to deliver about 1.8 Bcf/d of Canadian gas; and Kern River has the
capacity to deliver approximately 700 MMcf/d from Rocky Mountain supply sources.
PGT completed a 755 MMcf/d expansion of its California capacity on November 1,
1993. In 1992, Kern River held an open season to determine interest in expanding
capacity to California by 200 MMcf; however, no planned expansions have since
been announced.
 
     Demand for natural gas in the California market is projected to be less
than capacity for some time to come. EPG maintains a strong competitive position
in the market by virtue of the fact that its pipeline is, and expects to remain,
the lowest-cost transporter of natural gas to California and the principal means
of moving gas from the San Juan Basin to the California border. EPG's pipeline
capacity to California is fully subscribed under long-term contracts which
provide for the payment of fixed reservation charges.
 
     EPG's largest single contract for interstate capacity to California is its
1,450 MMcf/d contract with SoCal, which has a primary term ending August 31,
2006. In 1992, SoCal relinquished 300 MMcf/d pursuant to this contract (out of
an original contract demand quantity of 1,750 MMcf/d), all of which was
subsequently subscribed by new firm shippers under long-term contracts. Pursuant
to this contract, SoCal has the option to relinquish an additional 300 MMcf/d of
capacity during the first quarter of 1996. PG&E has a contract for 1,140 MMcf/d
of firm capacity rights on EPG's system. This contract has a primary term ending
December 31, 1997. CPUC has directed PG&E to maintain 600 MMcf/d of capacity on
EPG's system to service PG&E's core and core subscription service customers. EPG
expects to offset potential future reductions in capacity commitments through
new contracts with various natural gas users in California which are now served
indirectly through SoCal and PG&E, as well as through the development of
additional East-of-California and northern Mexico markets.
 
     In general, natural gas faces varying degrees of competition from
electricity, coal and oil. Competitive pressure from alternative fuels is less
prevalent in EPG's market area due to strict environmental regulations in
California.
 
  Environmental
 
     Accruals for environmental compliance costs are established when
environmental assessments and/or remediation are probable, and when costs can be
reasonably estimated. As of December 31, 1993, EPG had a reserve of $38 million
for the following environmental contingencies with income statement impact:
 
     1 -- EPG has been conducting remediation of PCB contamination at its
     facilities. The majority of the required PCB remediation has been
     completed. Future PCB remediation costs are estimated to range between $8
     million and $11 million over the next five years.
 
     2 -- EPG executed an Administrative Order on Consent with EPA on June 25,
     1993 to conduct a RI/FS for a BI site located in Statesville, North
     Carolina, that has been identified for cleanup. BI and EPG have entered
     into an agreement to jointly fund the RI/FS for the site. EPG's share of
     the potential remediation costs is estimated to be between $17 million and
     $20 million over a 30 year period.
 
     3 -- On November 2, 1993, in accordance with an EPA order, EPG and ARCO
     submitted work plans for remediation of the subsurface at the Prewitt
     Refinery in McKinley County, New Mexico. EPG and ARCO have a cost sharing
     agreement to each pay one-half of any remediation costs at this site. EPG's
     share of the remediation costs is estimated to be between $10 million and
     $20 million over a 30 year period.
 
     4 -- EPG is involved in other environmental assessment and remediation
     activities which include two additional CERCLA sites (Fountain Inn, South
     Carolina and Odessa, Texas) and one state Superfund site (Etowah,
     Tennessee). The amount reserved as of December 31, 1993 will cover these
     and other small environmental assessments and other remediation projects.
 
                                       17
<PAGE>   20
 
EPG also has potential expenditures, of a capital nature, for the following
environmental projects:
 
     1 -- EPG has analyzed CAAA, and believes that these rules will impact the
     Company's operations primarily in the following areas: (i) potential
     required reductions in the emissions of NOx in non-attainment areas; (ii)
     the requirement for air emissions permitting of existing facilities; and
     (iii) enhanced monitoring of air emissions. The Company anticipates
     capitalizing the equipment costs associated with complying with CAAA and
     estimates that approximately $5 million to $27 million will be spent during
     the 1995 through 1997 time frame. However, EPA's proposed enhanced
     monitoring rules, when finalized, could potentially impose greater costs to
     the Company.
 
     2 -- EPG has been conducting remediation of mercury contamination at
     certain facilities and is replacing mercury containing meters with dry flow
     devices. The remaining remediation costs are estimated to be between $8
     million and $12 million, most of which will be incurred over the next two
     years. EPG will close and retire about 5,400 earthen siphon/dehydration
     pits in the San Juan Basin as recently required by certain environmental
     regulations. EPG estimates costs of approximately $17 million to $25
     million to retire these pits over the next two years. The mercury
     remediation and pit closure costs, which are associated with the retirement
     of equipment, will be recorded as adjustments to accumulated depreciation,
     as required by regulatory accounting.
 
     On December 21, 1993, EPA issued EPG a Notice of Liability for the CSMRI
site in Golden, Colorado. Because EPA has not yet determined the volume of
hazardous substances sent to the site by all parties, there is no way to
estimate EPG's potential share of remediation costs. However, based on the
volumes EPA presently lists as contributed by EPG and other potentially
responsible parties, it appears that EPG is a minor contributor.
 
     It is possible that new information or future developments could require
the Company to reassess its potential exposure related to environmental matters.
As such information or developments occur, contingency amounts will be adjusted
accordingly.
 
  Common Stock Transactions Subsequent to the Offering
 
     For the year ended December 31, 1993, EPG paid approximately $40 million in
dividends. On January 14, 1994, EPG's Board of Directors declared a quarterly
dividend of $0.3025 per share on EPG's common stock, payable on April 4, 1994 to
shareholders of record on March 11, 1994.
 
     On October 22, 1992, EPG's Board of Directors authorized the repurchase of
up to two million shares of EPG's outstanding common stock from time to time in
the open market. Shares repurchased are held in EPG's treasury and are expected
to be used in connection with employee stock option plans to minimize dilution
to existing shareholders. During 1992, EPG acquired 812,773 shares of its common
stock for an aggregate value of $24 million and in the fourth quarter reissued,
in connection with employee stock option plans, 628,258 shares of common stock
out of treasury stock for an aggregate value of $11 million. The 184,515
remaining shares were reissued through April 1993, in connection with employee
stock option plans, for an aggregate value of $5 million.
 
     During 1993, EPG acquired 509,095 shares of its common stock for an
aggregate value of $18 million and subsequently reissued, in connection with
employee stock option plans, 22,734 shares of its common stock out of treasury
stock for an aggregate value of $0.5 million. As of December 31, 1993, EPG had
486,361 shares of treasury stock. In addition, from April 1993 through December
1993, EPG issued 43,394 shares of common stock in connection with employee stock
option plans.
 
     A total of 2,300 and 132,700 restricted shares of EPG's common stock were
granted to certain employees for 1993 and 1992, respectively. The market value
of such shares awarded was approximately $0.1 million and $2.8 million in 1993
and 1992, respectively.
 
Capital Expenditures
 
     The Company's planned capital expenditures for 1994 of approximately $210
million are primarily for maintenance of business, system expansion and system
enhancement. These expenditures are expected to be
 
                                       18
<PAGE>   21
 
financed through internally generated funds. Capital expenditures for 1993 were
$164 million compared to $246 million for 1992. The decrease was due primarily
to the 1992 completion of system expansion and enhancement projects.
 
     On July 7, 1992, EPG filed an application with FERC, which was amended on
November 27, 1992, to expand the delivery capacity of its system in the vicinity
of Yuma, Arizona and, through an extension of its system south to San Luis Rio
Colorado, Sonora, Mexico, to serve northern Mexican markets. The proposed
expansion would provide shippers the opportunity to deliver natural gas to
Mexican markets in northern Baja California via new pipeline capacity of 348
MMcf/d. This project is expected to cost approximately $71 million and will be
financed through internally generated funds or through short-term borrowings. On
November 29, 1993, FERC issued an order which approved the siting, construction
and operation of facilities necessary for a border crossing facility in Yuma,
Arizona which would connect the proposed extension with pipeline facilities in
Mexico. The order also made a preliminary determination on environmental issues.
FERC is deferring action on the remainder of the July 7, 1992 filing until EPG
demonstrates that it has long-term executed contracts or binding precedent
agreements for a substantial amount of the firm capacity of the proposed
facilities.
 
     EPG is a member of a five-company consortium that plans to build the
proposed Samalayuca II Power Plant near Ciudad Juarez, Mexico. On December 17,
1992, an award for construction was granted to the consortium by the Comision
Federal de Electricidad, the Mexican government-owned utility. On March 16,
1993, EPG filed an application with FERC to expand its system in order to
provide natural gas service to the proposed Samalayuca II Power Plant and to an
existing power plant in the same location. The proposed expansion would provide
an additional 300 MMcf/d of capacity at a cost of approximately $57 million and
will be financed through internally generated funds or through short-term
borrowings. In the November 29, 1993 order, FERC also approved the proposed
border crossing facility south of Clint, Texas which would connect EPG's
facilities with facilities in Mexico. FERC is deferring action on the remainder
of the March 16, 1993 filing until EPG demonstrates that it has long-term
executed contracts or binding precedent agreements for a substantial amount of
the firm capacity of the proposed facilities.
 
     On December 29, 1993, PG&E, SoCal and the CPUC jointly filed a motion with
FERC seeking clarification or rehearing of the November 29, 1993 FERC order for
both the Yuma, Arizona and the Samalayuca II Power Plant projects discussed
above.
 
     On March 17, 1993, MPC filed an application, which was amended on November
8, 1993, for a certificate of public convenience and necessity to build and
operate a 475 MMcf/d expansion of its existing system. The proposed expansion
will extend from MPC's existing east lateral located near Bakersfield,
California approximately 352 miles northward to the vicinity of Sacramento and
the East Bay area near San Francisco. The expansion will also include 56 miles
of looping of the existing pipeline along with 207 miles of laterals. The
estimated cost of the entire system is $467 million which is expected to be
funded primarily through project financing. MPC expects to receive its FERC
certificate in early 1994 and put the expansion into service in January 1996.
 
     On December 16, 1993, FERC held a public conference to examine a
jurisdictional question raised by CPUC and PG&E regarding MPC's system
expansion. The primary issue is whether FERC or CPUC should have jurisdiction
over the proposed expansion. Written comments were filed by interested parties
on January 10, 1994, with a final decision by FERC expected in early 1994.
 
Other
 
     In January 1993, EPG experienced flood damage to its pipeline system in the
Gila, Arizona area due to heavy rain. Since that time, EPG has been incurring
costs for repairs and expects to be reimbursed through its property insurance
policies once all repairs have been completed.
 
RESULTS OF OPERATIONS
 
 Year Ended December 31, 1993 Compared to Year Ended December 31, 1992
 
     Operating revenues for the year ended December 31, 1993 were $106 million
higher than for the same period of 1992. New system rates and a new rate design
placed into effect February 1, 1993, resulted in a $41 million increase in
revenues which was comprised of an increase in reservation revenues of $111
million
 
                                       19
<PAGE>   22
 
offset by a decrease in transportation revenues of $70 million. The
consolidation of MPC contributed $27 million to the increase. Higher production
area rates and volumes increased revenues by $3 million and $7 million,
respectively. Higher sales rates increased revenues by $34 million; however,
lower sales volumes offset that increase by $5 million. In addition, the sale of
gas in storage contributed $18 million to the increase in revenues; this
increase is offset in operating charges. Offsetting the increase in operating
revenues was a decrease of $13 million due to lower transportation volumes, a
decrease in return on take-or-pay receivables of $4 million and a decrease in
liquid revenues of $2 million.
 
     Operating charges were $62 million higher for the year ended December 31,
1993 compared to the same period for 1992. Higher average cost of gas
contributed $39 million to the increase. In addition, the sale of gas in storage
contributed $18 million to the increase in operating charges; this increase is
offset in operating revenues. Higher operation and maintenance costs of $26
million were due primarily to an accrual for estimated take-or-pay
undercollections, the consolidation of MPC and increases in employee benefit
costs and outside contractors fees, primarily related to environmental clean-up.
This increase is partially offset by lower stock related benefit costs. An
increase of $3 million in other taxes is primarily due to the consolidation of
MPC and an increase in ad valorem taxes. The increase in operating charges was
partially offset by lower depreciation rates after giving effect to the rate
settlement. Additionally, lower gas sales volumes resulted in a decrease in
operating charges of $4 million.
 
     EPG's throughput for 1993 was 1,306 Bcf compared to 1,357 Bcf in 1992. This
decrease is due to lower deliveries to the utility electric generation market
resulting from the availability of excess hydroelectric power in the California
markets. The lower deliveries to California were partially offset by higher
throughput to off-system markets.
 
     Interest and debt expense for the year ended December 31, 1993 was $7
million higher than for the same period of 1992 due primarily to the
consolidation of MPC.
 
     Allowance for funds used during construction ("AFUDC") was $2 million lower
for the year ended December 31, 1993 than for the same period in 1992 due to a
decrease in expansion project expenditures during 1993.
 
     Other-net was $6 million higher for the year ended December 31, 1993
compared to the same period for 1992. Contributing to the higher expense was a
$6 million increase related to environmental accruals; a $4 million reduction in
direct bill interest income; and a $4 million reduction in partnership earnings
due to the consolidation of MPC. The increase was offset by lower interest
expense of $4 million on tax adjustments and $3 million of interest income
related to the recovery of EPG's investment in its underground storage facility.
 
 Year Ended December 31, 1992 Compared to Year Ended December 31, 1991
 
     Operating revenues for 1992 were $68 million higher than 1991. The overall
increase in revenues was due primarily to new rates placed into effect on
January 1, 1992. The new rates resulted in a $156 million increase in
reservation revenues, which reflects the shift from firm sales service to firm
transportation service. By unbundling its sales service, the Company's sales
occur at the mainline receipt point as opposed to the delivery point. Lower
accruals for regulatory issues resulted in an increase in revenues of $42
million. Higher sales volumes resulted in increased revenues of $88 million;
however, lower sales rates offset that increase by $23 million. Also offsetting
the increases were lower transportation rates which resulted in decreased
revenues of $113 million. Other decreases affecting the improved 1992 results
were a $30 million decrease in production area revenues resulting from the sale
of certain gathering and processing facilities and lower rates, a $28 million
decrease in return on take-or-pay receivables, an $11 million decrease in liquid
revenues and a $6 million decrease in interest on receivables from customers.
 
     Operating charges were $68 million higher for 1992 compared to 1991. The
increase was primarily due to higher purchased gas costs. Higher sales volumes
resulted in a $72 million increase in purchased gas costs; however, this
increase was partially offset by a $15 million decrease due to lower gas
purchase prices. A $12 million increase in depreciation and a $7 million
increase in taxes, other than income taxes, both resulting from system
expansions, also contributed to the increase in operating charges. An $8 million
decrease in operation and maintenance costs was principally due to reductions in
fees paid to outside operators and
 
                                       20
<PAGE>   23
 
contractors, partially offset by additional costs allocated to the Company from
BR resulting from the separation of the two companies.
 
     Throughput for 1992 was 1,357 Bcf compared to 1,409 Bcf in 1991. The
decrease in throughput was principally due to increased competition in the
California markets. Lower deliveries to California were partially offset by
higher throughput to the East-of-California and off-system markets.
 
     Interest and debt expense was $68 million for 1992 compared with $98
million for 1991. The decrease was primarily due to a $18 million reduction in
interest on commercial paper, which balance was repaid in December 1991, and a
$17 million reduction in interest on rate refund, which refund was made in
October 1991. These decreases were partially offset by an $8 million increase
resulting from the cost of the take-or-pay receivables sale.
 
     Interest income from BR was $2 million for 1992 compared with $38 million
for 1991. This decrease was due to the dividends declared and paid to BR in
December 1991 and in January and February 1992, from the balance owed by BR to
EPG under the intercorporate cash management arrangement.
 
     Reported as other-net was $2 million expense for 1992 compared with $12
million income for 1991. Contributing to lower income in 1992 was a $5 million
decrease in net gains on dispositions of facilities; a $7 million reduction in
MPC partnership earnings resulting from a non-recurring income adjustment in
1991; and a $6 million increase in other interest. A $6 million increase in
income from temporary investments and other interest income partially offset the
lower income.
 
OTHER
 
     The Financial Accounting Standards Board issued Statement of Financial
Accounting Standards No. 106 ("SFAS 106") requiring companies to account for
other post-retirement employee benefits ("OPEBs") (principally retiree medical
costs) on an accrual basis versus the pay-as-you-go basis traditionally followed
by most United States companies. The Company adopted SFAS 106 effective January
1, 1993.
 
     The Company provides a non-contributory defined benefit postretirement
medical plan that covers employees who retired on or before March 1, 1986 and
limited postretirement life insurance for employees who retire after January 1,
1985. As such, the Company's obligation to accrue for OPEBs is primarily limited
to the fixed population of retirees who retired on or before March 1, 1986. The
medical plan is funded to the extent employer contributions are recoverable
through rates.
 
     EPG began recovering through its rates the OPEB costs included in the
settlement agreement. To the extent actual OPEB costs exceed the amounts
reflected in the settlement agreement, a regulatory asset has been recorded.
Management expects such amounts to be fully recovered through its rates.
 
     The Financial Accounting Standards Board issued Statement of Financial
Accounting Standards No. 112 ("SFAS 112") which requires companies to account
for benefits to former or inactive employees after employment but before
retirement (referred to in SFAS 112 as "postemployment benefits"). SFAS 112 is
effective for the fiscal years beginning after December 15, 1993. Postemployment
benefits include every form of benefit provided to former or inactive employees,
their beneficiaries and covered dependents. Benefits include, but are not
limited to salary continuation, supplemental unemployment benefits, severance
benefits, disability-related benefits (including workers' compensation), job
training and counseling and continuation of benefits such as health care
benefits and life insurance coverage. The cumulative effect at January 1, 1994
of adopting SFAS 112 is estimated to be approximately $8 million. Management
expects to fully recover its postemployment benefit costs through rates.
 
     The Revenue Reconciliation Act of 1993, enacted in August 1993, changed the
corporate income tax rate from 34 to 35 percent effective January 1, 1993. As a
result, the Company's current year provision for income tax expense was adjusted
in the third quarter of 1993 by approximately $1 million, of which $0.5 million
is related to the balance of deferred income taxes at December 31, 1992. In
addition, the balance of accumulated deferred income taxes at January 1, 1993
was increased $5 million in accordance with Statement of Financial Accounting
Standards No. 109 ("SFAS 109"), and a corresponding regulatory asset was
recorded. Management expects such amounts to be fully recovered through its
rates.
 
     Deferred credits, in the accompanying Consolidated Balance Sheet, include
excess deferrals resulting from the reduction of the statutory federal tax rate
from 46 to 34 percent on July 1, 1987.

                              ACCOUNTING POLICIES
 
PRESENTATION AND PRINCIPLES OF CONSOLIDATION
 
     The consolidated financial statements include the accounts of the Company.
All significant intercompany transactions of continuing operations are accounted
for at market prices and have been eliminated in consolidation. The financial
statements for previous periods include certain reclassifications that were made
to conform to the current presentation. Such reclassifications have no impact on
reported income or stockholders' equity.
 
     On June 1, 1993, the Company acquired from a wholly owned subsidiary of
Enron Corp., that subsidiary's 50 percent interest in MPC, a general
partnership. This acquisition gives the Company 100 percent ownership of MPC.
The operating results of MPC are included in the Company's consolidated results
of operations for the months of May 1993 through December 1993. The Company's
previously owned 50 percent equity interest in MPC is included in other-net in
the accompanying Consolidated Statement of Income.
 
     In September 1991, a dividend of the common stock of EPG's Oil and Gas
Operations Segment was made by EPG to its then parent company, TEPCO. The
accompanying financial statements and notes reflect the discontinuance of the
Oil and Gas Operations Segment.
 
CASH AND TEMPORARY CASH INVESTMENTS
 
     Short-term investments purchased with an original maturity of three months
or less are considered cash equivalents. Through December 31, 1991, cash and
temporary cash investments also included excess cash advanced by the Company to
its then parent company, BR, under an intercorporate cash management
arrangement.
 
ACCUMULATED PROVISION FOR UNCOLLECTIBLE ACCOUNTS RECEIVABLE
 
     The Company has established a provision for losses on trade accounts
receivable which may become uncollectible. Collectibility of trade receivables
is reviewed regularly, and the allowance for bad debts is adjusted as necessary
under the specific identification method. The balance of this provision at
December 31, 1993 and 1992 was $3.9 million and $5.1 million, respectively.
 
ACCOUNTING FOR REGULATED OPERATIONS
 
     EPG and MPC are subject to the regulations and accounting procedures of
FERC and therefore, continue to follow the reporting and accounting requirements
of Statement of Financial Accounting Standards No. 71 ("SFAS 71"). Accounting
methods for companies subject to cost-of-service regulation may differ from
those used by non-regulated companies. However, when the accounting method
prescribed by the regulatory authority is used for rate-making, such accounting
conforms to the generally accepted accounting principle of matching costs
against the revenues to which they apply.
 
     Transactions which have been recorded differently than a non-regulated
entity include the following: (i) take-or-pay payments recoverable from
customers, based upon transportation volumes, have been recorded as an asset,
net of allowance; (ii) losses on reacquired debt have been recorded in other
assets and are being amortized over the life of the original or replacement
debt; (iii) revenue related to the implementation of SFAS 109 has been recorded
as a deferred credit and is being amortized into income; (iv) adjustment to
reflect the increase in the federal income tax rate has been recorded in other
regulatory assets to be recovered in future rates; (v) excess amounts of OPEB
costs have been recorded in other regulatory assets to be recovered in future
rates; (vi) a portion of EPG's investment in its underground storage facility
has been recorded as an asset and is being recovered in accordance with the
settlement agreement; (vii) the cost of equity funds used during construction
has been capitalized; (viii) MPC's excess amounts due to straight-line
depreciation rates versus approved depreciation rates have been recorded as
other regulatory assets to be

recovered in future rates and (ix) MPC's deferred taxes on the equity portion of
AFUDC have been recorded in other regulatory assets to be recovered in future
rates.
 
ACCOUNTING FOR GAS IMBALANCES
 
     EPG currently accounts for gas imbalances due to or due from shippers and
operators. Gas imbalance payables and receivables are maintained at a net legal
entity basis in accordance with Statement of Financial Accounting Standards No.
105. Gas imbalances prior to October 1, 1993 are valued at the 1992 average El
Paso System index price as prescribed in EPG's tariff. Gas imbalances subsequent
to October 1, 1993 are valued at the current quarterly average El Paso System
index price.
 
     The Company has established a provision for gas imbalances which may become
uncollectible. Collectibility of gas imbalances is reviewed regularly and the
provision is adjusted as necessary under the specific identification method. The
balance of the provision at December 31, 1993 and 1992 was $5.6 million and
$12.1 million, respectively.
 
INCOME TAXES
 
     Income taxes are based on income reported for tax return purposes and a
provision for deferred income taxes. Deferred income taxes are provided to
reflect the tax consequences in future years of differences between the
financial statement and tax bases of assets and liabilities at each year end.
Tax credits are accounted for under the flow-through method, which reduces the
provision for income taxes in the year the tax credits first become available.
 
     Pursuant to a tax sharing agreement between EPG and BR covering periods
prior to July 1992, EPG is responsible for its tax liabilities and those of its
subsidiaries. EPG is required to pay BR its allocable portion of the
consolidated federal tax liability and combined state income tax liability.
 
PROPERTY, PLANT AND EQUIPMENT
 
     Included in the Company's property, plant and equipment is construction
work in progress of approximately $53 million and $93 million at December 31,
1993 and 1992, respectively. An allowance for both debt and equity funds used
during construction is included in the cost of the Company's property, plant and
equipment.
 
     EPG's properties are depreciated using the composite method. Straight-line
depreciation rates for 1993 and 1991 were 1.6 percent for transmission
facilities. For 1992, the depreciation rate for transmission facilities was 2.67
percent adjusted to 1.6 percent in accordance with the settlement agreement. The
depreciation rate for gathering facilities was 3.5 percent for 1993, 1992 and
1991.
 
     MPC's depreciation rates reflect a levelized cost-of-service approach and a
25-year depreciation life. MPC's depreciation rate for its plant during the
first 15 years increases gradually from 1.48 percent in 1992 to 8.76 percent in
2007. The depreciation rates are designed to recover approximately 80 percent of
MPC's plant balance by March 1, 2007. The depreciation rate related to years 16
through 25 will be determined in future rate proceedings. (See "Accounting for
Regulated Operations" of Accounting Policies.)
 
     Additional acquisition cost assigned to utility plant represents EPG's
portion of the excess of allocated acquisition cost over historical cost that
resulted from the 1983 acquisition of EPG's former parent, TEPCO, by BR's former
parent, BNI. These costs are being amortized on a straight-line basis over the
estimated remaining life of the properties.

                        ACCOUNTING POLICIES (CONTINUED)
 
     Costs of properties that are not operating units, as defined by FERC, which
are retired, sold or abandoned are charged or credited, net of salvage, to
accumulated depreciation and amortization. Gains or losses on sales of operating
units are credited or charged to income.
 
INVENTORIES
 
     Inventories are carried on either the first-in first-out or average cost
method at the lower of cost or market. Gas in storage inventories at December
31, 1992 were carried at cost determined on a last-in first-out basis. During
1993, EPG sold its gas in storage inventory in accordance with the settlement
agreement with EPG's customers and FERC staff. Inventories at December 31, 1993
and 1992 consist of the following components:

</TABLE>
 
RECOVERABLE EXCESS GAS COSTS
 
     The cash flow statement for 1991 shows recoveries of recoverable excess gas
costs. These costs represent the cumulative excess of actual purchased gas costs
over the average of these costs included in EPG's gas sales rates. FERC's August
14, 1991 order provided for a portion of the September 1, 1991 recoverable
excess gas costs balance to be offset against refund obligations. The remainder
of the costs, $25 million, was recorded against previously established accruals.
Effective with the implementation of the 1991 order, EPG no longer records
recoverable excess gas costs.
 
TAKE-OR-PAY SETTLEMENTS
 
     Assets resulting from the resolution of take-or-pay obligations include
recoupable take-or-pay prepayments and take-or-pay buy-out and buy-down
receivables. Recoupable prepayments result when EPG pays for, but does not
physically receive, gas and retains the right to take such gas in the future,
generally over five years. Take-or-pay buy-outs and buy-downs represent costs
paid to natural gas producers for the termination or modification of gas
purchase contracts. In exchange for EPG's agreement to absorb 25 percent of its
take-or-pay buy-out and buy-down costs, FERC regulations provide for the direct
billing of 25 percent of such costs to EPG's customers. In addition, such
regulations allow EPG to recover the remaining 50 percent of its buy-out and
buy-down costs through a surcharge added to its transportation rates.
 
EARNINGS PER SHARE
 
     Earnings per share of common stock is based on the weighted average number
of shares of common stock outstanding during the year. The weighted average
number of shares of common stock outstanding for 1993, 1992 and 1991 were
37,212,192, 36,049,135 and 31,421,731, respectively. Stock options are the only
common stock equivalents and are currently not dilutive.

 1.  RATES AND REGULATORY MATTERS
 
  General Rate Filings and Other
 
     On July 1, 1991, EPG filed for FERC approval of new system rates and placed
the proposed new rates into effect on January 1, 1992, subject to refund. On
July 31, 1992, EPG again filed for new rates to recover increased costs and
return on rate base associated with EPG's expansion and modernization projects.
These rates were effective on February 1, 1993, subject to refund. In the July
1992 filing, EPG's rate base increased from $752 million to approximately $1.2
billion. EPG made its compliance filing on December 31, 1992, in accordance with
the Restructuring Rules.
 
     In January 1993, EPG, certain of its customers and FERC staff reached a
settlement agreement which led to the resolution of the above mentioned rate and
restructuring proceedings. The settlement agreement was filed in January 1993 to
supersede EPG's December 31, 1992 compliance filing. As required by FERC order,
EPG filed revised rates on September 14, 1993, which implemented the settlement
agreement effective October 1, 1993. Under the settlement agreement, EPG
refunded a total of approximately $56 million, inclusive of interest, in the
fourth quarter of 1993. EPG had provided for these rate refunds as revenues were
collected.
 
     The settlement agreement provides for the accelerated recovery of a
substantial portion of EPG's investment in its underground storage facility.
This is being recovered by a demand charge mechanism over the period from
October 1, 1993 through December 31, 1996. The amount to be recovered was
approximately $56.7 million plus interest accruing beginning February 1, 1993 at
the FERC allowed rate, which approximates the prime rate. The amount recovered
through December 31, 1993 was $19 million. The outstanding balance at December
31, 1993 was $37 million, of which $12 million is included in other current
assets and $25 million is included in other assets in the accompanying
Consolidated Balance Sheet. The settlement agreement also established new
depreciation rates for certain of EPG's facilities effective January 1, 1992.
 
     On August 14, 1991, FERC approved an order resolving all of the issues in
EPG's December 1987 rate case filing and certain other pending matters which
became effective on September 1, 1991. The order provided for: (i) the
establishment of revised rate levels for the period July 1, 1988 through the
effective date of EPG's next rate change, which occurred on January 1, 1992; and
(ii) payment of certain refunds for the period July 1, 1988 through August 31,
1991. EPG disbursed to its customers $252 million in October 1991 in accordance
with the order. The total refund obligation at September 1, 1991 was $369
million before certain offsets, including an unbilled portion of the $169
million of recoverable excess gas costs. The net refund obligation and the
remaining balance of the recoverable excess gas costs, $25 million, were
recorded against previously established accruals.
 
     Pursuant to the Restructuring Rules, MPC filed its restructuring plan on
November 3, 1992. On March 2, 1993, FERC issued an order essentially approving
MPC's compliance filing, subject to changes, which were made in an amended
restructuring plan on March 29, 1993. Several of MPC's customers filed protests
and requests for rehearing of the March 2, 1993 FERC order. The rehearing
requests were denied, and FERC approved the amended restructuring plan on July
9, 1993, with an effective date of August 1, 1993. On October 15, 1993, FERC
issued an order which denied requests for rehearing of the July 9, 1993 order.
Several of MPC's customers have filed petitions for review of the March 2, 1993,
July 9, 1993, and October 15, 1993 orders with the United States Court of
Appeals which are currently pending.
 
     The primary issues on appeal pertain to FERC's requirement that MPC's rates
for firm transportation service be based upon SFV rate design rather than MFV
rate design. The application of SFV rates requires MPC's existing firm shippers
to pay a higher proportion of their total transportation rate in the reservation
component of the rate, and this increases aggregate transportation charges for
low load factor shippers. Such

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
shippers have contended that FERC's application of SFV rate design to MPC
unlawfully abrogates the rate provisions of MPC's service agreements and
constitutes an unlawful rate increase. MPC believes the United States Court of
Appeals will uphold SFV rates as applied to MPC.
 
  Take-or-Pay Settlements
 
     Since 1987, EPG has made, or has committed to make, buy-out and buy-down
payments totaling $1.5 billion to resolve past and future take-or-pay exposure,
to terminate and reform gas purchase contracts, to amend pricing and take
provisions of gas purchase contracts and to settle related litigation. In
certain cases, EPG resolved claims by making recoupable prepayments. At December
31, 1993 and December 31, 1992, the recoupable prepayment balances were $9
million and $19 million, respectively. These payments resolved virtually all the
outstanding producer claims asserted against EPG and terminated or prospectively
reformed substantially all of EPG's remaining gas purchase contracts, with the
result that EPG no longer has any material take-or-pay exposure.
 
     EPG has filed to recover $1.1 billion of its buy-out and buy-down costs
under FERC cost recovery procedures. The collection period for the direct bill
portion of the take-or-pay buy-out and buy-down costs extends through May 1994.
The collection period for the volumetric surcharge portion of such costs extends
through March 1996. Through December 31, 1993, EPG had recovered approximately
$1.0 billion; of that recovery, $361 million was collected by direct bill and
$682 million by volumetric surcharge. EPG has established a reserve for that
portion of the volumetric surcharge receivables balance which is unlikely to be
collected over the period through March 1996, based on current throughput
projections. The balance of this reserve was $19 million at December 31, 1993.
 
     Under FERC procedures, take-or-pay cost recovery filings may be challenged
by pipeline customers on prudence and certain other grounds. In October 1992,
FERC approved an order, subject to rehearing, resolving all but one of the
outstanding issues regarding EPG's take-or-pay proceedings. The remaining issue
involves the claim by several customers that EPG has sought to recover an
excessive amount for the value of certain production properties which were
transferred to a producer as part of a 1989 take-or-pay settlement. On March 8,
1993, an initial decision from the presiding ALJ was rendered which, if adopted
without changes by FERC, would require EPG to refund to or forgo collection from
its customers of up to $30 million, plus interest. Exceptions to this initial
decision were filed with FERC by both parties on April 7, 1993. On April 27,
1993, briefs opposing exceptions were filed by the same parties as well as by
FERC staff. EPG has established adequate reserves for this issue and does not
believe that the ultimate outcome will have a materially adverse effect on the
Company's financial condition or results of operations.
 
     On January 14, 1992, EPG completed a sale of substantially all of its
remaining take-or-pay buy-out and buy-down receivables. The sale totaled $325
million, including $305 million of cash received at closing, which was used to
repay $300 million of a payable to BR. The receivables sold in this transaction
included $104 million which was recovered through direct bill and $221 million
to be recovered through volumetric surcharge. The volumetric surcharge portion
of the sale has been accounted for as a financing transaction because EPG is
subject to certain recourse provisions related to such receivables. At December
31, 1993 and December 31, 1992, $87 million and $125 million, respectively, of
the volumetric surcharge portion of the receivables sold remained outstanding.
Amounts collected related to the take-or-pay receivables sold are remitted to
the purchasers of the receivables.
 
 2.  ACQUISITION
 
     On June 1, 1993, the Company acquired from a wholly owned subsidiary of
Enron Corp., that subsidiary's 50 percent interest in MPC for approximately $40
million in cash, representing the approximate book value of

flow, gives the Company 100 percent ownership of MPC. The acquisition was
accounted for using the purchase method.
 
     In conjunction with the acquisition, the following liabilities were
assumed:

     On December 5, 1991, EPG commenced a tender offer with respect to the 9.45%
Notes and 8 5/8% Debentures. Pursuant to the tender offer, in December 1991, EPG
purchased $207 million aggregate principal amount of the 9.45% Notes for $228
million and $93 million aggregate principal amount of 8 5/8% Debentures for $93
million. In January 1992, EPG purchased an additional $46 million and $41
million of aggregate principal amounts of the 9.45% Notes and 8 5/8% Debentures,
respectively. Funds for these purchases were provided by proceeds from
borrowings under the BR Loan Agreements described below. In addition, on
December 19, 1991, EPG called for redemption, on January 23, 1992, of all the
outstanding 9 5/8% Debentures ($100 million aggregate principal amount) at a
price equal to 106.84 percent of their principal amount.
 
     EPG had a Commitment Agreement with BR under which it could borrow up to
$300 million. EPG also maintained Loan Agreements with BR under which it could
borrow up to $500 million. As of December 31, 1991, $300 million was outstanding
under the Commitment Agreement and $325 million was outstanding under the Loan
Agreements. In January 1992, EPG borrowed an additional $109 million under the
Loan Agreements. Borrowings under the Loan Agreements were used to pay for the
purchase of the 9.45% Notes and the 8 5/8% Debentures in December 1991 and
January 1992 and the payment of related transaction costs.
 
     In January 1992, EPG issued $575 million principal amount of new debt
securities consisting of $100 million of 6.90% Notes due 1997, $215 million of
7 3/4% Notes due 2002 and $260 million of 8 5/8% Debentures

due 2022. The net proceeds of $569 million received from such issuance were used
to repay $434 million of borrowings under the Loan Agreements with BR, to redeem
$107 million of 9 5/8% Debentures and for general corporate purposes ($28
million) including costs related to the transactions discussed above.
 
     EPG repaid its outstanding commercial paper in December 1991 with
borrowings under the Commitment Agreement with BR. The proceeds from the sale of
the take-or-pay receivables were used to repay the borrowings under the
Commitment Agreement with BR.
 
     The Commitment Agreement and the Loan Agreements with BR were terminated
prior to the completion of the Offering. In February 1992, EPG established a
$300 million revolving credit facility with a group of banks which facility
expires in March 1996. As of December 31, 1993, there were no borrowings
outstanding under this facility. Approximately $1 million of commercial paper
was outstanding as of December 31, 1993.
 
     EPG must comply with various restrictive covenants contained in its debt
agreements which include, among others, maintaining consolidated tangible net
worth (as defined in the agreements) of at least $400 million. Also, EPG's
consolidated debt and guaranties to capitalization ratio cannot exceed 70
percent. Furthermore, certain EPG subsidiaries (other than any project financing
subsidiary, as defined in the agreements) may not incur debt obligations which
would exceed $75 million in the aggregate. As of December 31, 1993, EPG's
consolidated tangible net worth exceeded the minimum restrictive covenant
requirement by $298 million, its consolidated debt and guaranties to
capitalization ratio was 47 percent and there were no subsidiary debt
obligations of those subsidiaries limited by the debt agreements.
 
     On September 30, 1991, MPC entered into a credit agreement ("Credit
Agreement") with a group of banks which provided a 15 year project financing
loan to MPC of up to $180 million. Total outstanding loan balances under the
Credit Agreement were $165 million and $170 million at December 31, 1993 and
1992, respectively. The loan is repayable in semiannual installments over the
period to March 31, 2007. Interest on the loan is payable quarterly.
 
     MPC has entered into interest rate swap agreements which effectively
convert $114.3 million of the current loan balance from floating-rate debt to
fixed-rate debt. MPC makes payments to counterparties at fixed rates and in
return receives payments at floating rates. Substantially all of the remaining
$50.5 million of loan principal had interest rates ranging from 3.9 percent to
4.3 percent during 1993. With the impact of the interest rate swap agreements,
the overall effective rate on the loan was approximately 7.6 percent during 1993
and 1992.
 
     Borrowings under the Credit Agreement are collateralized by a priority
interest in the Company's partnership interests and certain other distributed
and undistributed partnership property. The Credit Agreement also contains

4. ENVIRONMENTAL
 
     Accruals for environmental compliance costs are established when
environmental assessments and/or remediation are probable, and when costs can be
reasonably estimated. As of December 31, 1993, EPG had a reserve of $38 million
for the following environmental contingencies with income statement impact:
 
     1 -- EPG has been conducting remediation of PCB contamination at its
     facilities. The majority of the required PCB remediation has been
     completed. Future PCB remediation costs are estimated to range between $8
     million and $11 million over the next five years.
 
     2 -- EPG executed an Administrative Order on Consent with EPA on June 25,
     1993 to conduct a RI/FS for a BI site located in Statesville, North
     Carolina, that has been identified for cleanup. BI and EPG have entered
     into an agreement to jointly fund the RI/FS for the site. EPG's share of
     the potential remediation costs is estimated to be between $17 million and
     $20 million over a 30 year period.
 
     3 -- On November 2, 1993, in accordance with an EPA order, EPG and ARCO
     submitted work plans for remediation of the subsurface at the Prewitt
     Refinery in McKinley County, New Mexico. EPG and ARCO have a cost sharing
     agreement to each pay one-half of any remediation costs at this site. EPG's
     share of the remediation costs is estimated to be between $10 million and
     $20 million over a 30 year period.
 
     4 -- EPG is involved in other environmental assessment and remediation
     activities which include two additional CERCLA sites (Fountain Inn, South
     Carolina and Odessa, Texas) and one state Superfund site (Etowah,
     Tennessee). The amount reserved as of December 31, 1993 will cover these
     and other small environmental assessments and other remediation projects.
 
EPG also has potential expenditures, of a capital nature, for the following
environmental projects:
 
     1 -- EPG has analyzed CAAA, and believes that these rules will impact the
     Company's operations primarily in the following areas: (i) potential
     required reductions in the emissions of NOx in non-attainment areas; (ii)
     the requirement for air emissions permitting of existing facilities; and
     (iii) enhanced monitoring of air emissions. The Company anticipates
     capitalizing the equipment costs associated with complying with CAAA and
     estimates that approximately $5 million to $27 million will be spent during
     the 1995 through 1997 time frame. However, EPA's proposed enhanced
     monitoring rules, when finalized, could potentially impose greater costs to
     the Company.
 
     2 -- EPG has been conducting remediation of mercury contamination at
     certain facilities and is replacing mercury containing meters with dry flow
     devices. The remaining remediation costs are estimated to be between $8
     million and $12 million, most of which will be incurred over the next two
     years. EPG will close and retire about 5,400 earthen siphon/dehydration
     pits in the San Juan Basin as recently required by certain environmental
     regulations. EPG estimates costs of approximately $17 million to $25
     million to retire these pits over the next two years. The mercury
     remediation and pit closure costs, which are associated with the retirement
     of equipment, will be recorded as adjustments to accumulated depreciation,
     as required by regulatory accounting.
 
     On December 21, 1993, EPA issued EPG a Notice of Liability for the CSMRI
site in Golden, Colorado. Because EPA has not yet determined the volume of
hazardous substances sent to the site by all parties, there is no way to
estimate EPG's potential share of remediation costs. However, based on the
volumes EPA presently lists as contributed by EPG and other potentially
responsible parties, it appears that EPG is a minor contributor.
 
     It is possible that new information or future developments could require
the Company to reassess its potential exposure related to environmental matters.
As such information or developments occur, contingency amounts will be adjusted
accordingly.

5. CORPORATE REORGANIZATION
 
     During 1992 and 1991, EPG completed several transactions in preparation for
its separation from BR. Among these transactions was the transfer of the net
assets of the Company's Oil and Gas Operations Segment to TEPCO, which is
reported as discontinued operations.
 
     In May 1991, EPG declared and paid a dividend of $175 million to TEPCO.
Effective August 31, 1991, EPG contributed its oil and gas cost-of-service
production properties to EPPC. In September 1991, EPG declared a dividend of all
its Oil and Gas Operations Segment to TEPCO. The total amount of that dividend
was $925 million, $500 million of which was a return of capital and,
accordingly, reduced additional paid-in-capital. TEPCO declared a dividend of
100 percent of the common stock of EPG to BR, TEPCO's parent company, effective
September 2, 1991.
 
     In December 1991, EPG declared and paid a dividend to BR of $55 million. In
January and February 1992, EPG declared and paid dividends totaling $274 million
to BR. These dividends were paid from the balance owed to EPG under an
intercorporate cash management arrangement.
 
     In March 1992, EPG completed the Offering. The proceeds from the Offering,
net of related costs, totaled approximately $96 million. On June 30, 1992, BR
distributed its 31.4 million shares of EPG's common stock, which represented
approximately 85 percent of EPG's outstanding common stock, to BR shareholders.
As a result, BR no longer retains an ownership interest in EPG.
 
  Discontinued Operations
 
     The following results of operations of the Oil and Gas Operations Segment
are presented as income from discontinued operations, net of income taxes, in
the accompanying Consolidated Statement of Income:

     The operations of EPG's cost-of-service production properties that were
contributed to EPPC on August 31, 1991, were reflected in the Company's Natural
Gas Operations Segment and are therefore not included in income from
discontinued operations. The net book value of the production properties was
$197 million on August 31, 1991. The earnings related to the cost-of-service
production properties are included in income from continuing operations and are
not material.
 
6. CAPITAL STOCK
 
     Under EPG's employee stock option plans, options may be granted to officers
and key employees at fair market value on the date of grant, exercisable in
whole or part by the optionee after completion of one to three years of
continuous employment from the grant date. Options are also granted to Directors
at fair market value on the date of grant and are exercisable immediately. Under
the terms of these plans, EPG may grant stock appreciation rights ("SARs") to
certain holders of stock options. SARs are subject to the same terms and
conditions as the related stock options. The stock option holder who has been
granted tandem SARs can elect to exercise either an option or a SAR. SARs
entitle an option holder to receive a payment equal to the difference between
the option price and the fair market value of the common stock of EPG at the
date of

exercise of the SAR. To the extent a SAR is exercised, the related option is
cancelled, and to the extent an option is exercised, the related SAR is
cancelled.
 
     On January 15, 1992, the Board of Directors of EPG granted options
exercisable for 722,300 shares of common stock effective upon the closing of the
Offering. One-third of the options became exercisable on December 19, 1992;
one-third became exercisable on January 15, 1994; and one-third will become
exercisable on January 15, 1995. On January 12, 1993, EPG's Board of Directors
granted stock options exercisable for 554,000 shares of common stock at $30.81
per share. The stock options vested on January 12, 1994. On March 18, 1993,
3,000 stock options were granted at $36.19 per share and became exercisable
immediately. On May 1, 1993, 3,000 stock options were granted at $38.19 per
share and became exercisable immediately. On July 22, 1993, 15,000 stock options
were granted at $37.25 per share and vested on January 22, 1994. On January 14,
1994, EPG's Board of Directors granted stock options exercisable for 655,100
shares of common stock at $36.875 per share which will vest on January 14, 1995.
In addition, stock options were granted for 3,000 shares of common stock at
$36.875 per share, which became exercisable immediately.
 
     After the Offering, 597,838 BR stock options and 100,730 BR SARs, at prices
ranging from $25.50 to $44.75 per share, were converted to EPG stock options and
SARs at prices ranging from $13.51 to $22.91 per share.

     At December 31, 1993, 321,286 stock options and 70,154 SARs were
exercisable at prices ranging from $13.51 to $38.19 per share. At December 31,
1992, 568,422 stock options and 105,203 SARs were exercisable at prices ranging
from $13.51 to $25.69 per share.
 
     SARs shown as cancelled in the table above were cancelled when the
underlying stock options were exercised. Stock options shown as cancelled in the

     The maximum number of shares for which stock options may be granted under
EPG's stock option plans are approximately seven million shares of common stock,
to be issued from shares held in EPG's treasury or out of authorized but
unissued shares of EPG's common stock, or partly out of each, as shall be
determined by EPG's Board of Directors.
 
     On October 22, 1992, EPG's Board of Directors authorized the repurchase of
up to two million shares of EPG's outstanding shares of common stock from time
to time in the open market. Shares repurchased are held in EPG's treasury and
are expected to be used in connection with EPG employee stock option plans to
minimize dilution to existing shareholders. During 1992, EPG acquired 812,773
shares of its common stock

for an aggregate value of $24 million and in the fourth quarter reissued, in
connection with EPG's employee stock option plans, 628,258 shares of common
stock out of treasury stock for an aggregate value of $11 million. The 184,515
remaining shares were reissued through April 1993, in connection with employee
stock option plans, for an aggregate value of $5 million.
 
     During 1993, EPG acquired 509,095 shares of its common stock for an
aggregate value of $18 million and subsequently reissued, in connection with
employee stock option plans, 22,734 shares of its common stock out of treasury
stock for an aggregate value of $0.5 million. As of December 31, 1993, EPG had
486,361 shares of treasury stock. In addition, from April 1993 through December
1993, EPG issued 43,394 shares of common stock in connection with EPG's employee
stock option plans.
 
     A total of 2,300 and 132,700 restricted shares of EPG's common stock were
granted to certain employees for 1993 and 1992 respectively. The market value of
such shares awarded was approximately $0.1 million and $2.8 million in 1993 and
1992, respectively.
 
     EPG has 25,000,000 shares of authorized preferred stock, par value $0.01
per share, none of which have been issued.
 
     For the year ended December 31, 1993, primary earnings per share of common
stock was $2.46 per share. If stock options exercised in 1993 had been exercised
on January 1, 1993, earnings per share would have remained at the same level.
For the year ended December 31, 1992, primary earnings per share of common stock
was $2.12 per share. If stock options exercised in December 1992 had been
exercised on January 1, 1992, earnings per share of common stock for 1992 would
have been $2.08.

     The Revenue Reconciliation Act of 1993, enacted in August 1993, changed the
corporate income tax rate from 34 to 35 percent effective January 1, 1993. As a
result, the Company's current year provision for income tax expense was adjusted
in the third quarter of 1993 by approximately $1 million, of which $0.5 million
is related to the balance of deferred income taxes at December 31, 1992. In
addition, the balance of accumulated deferred income taxes at January 1, 1993
was increased $5 million in accordance with SFAS 109, and a corresponding
regulatory asset was recorded. Management expects such amounts to be fully
recovered through its rates.
 
     Deferred credits, in the accompanying Consolidated Balance Sheet, include
excess deferrals resulting from the reduction of the statutory federal tax rate
from 46 to 34 percent on July 1, 1987.
 
 9.  PENSION PLANS
 
     The Company previously participated in BR's pension plans, which were
non-contributory defined benefit plans covering substantially all employees. The
benefits were based on the number of years of credited service and the highest
five-year average compensation levels. Contributions to the plans were
determined by BR and were limited to amounts that were deductible for tax
purposes.
 
     In January 1992, the Company established its own pension plans with
provisions similar to those of the BR plans. Upon separation from BR, the
Company's qualified pension plan received assets equal to the accumulated
benefit obligation relating to the Company's employees.

The 1993 weighted average discount rate and rate of increase in future
compensation levels used in determining the actuarial present value of the
projected benefit obligation were 7.5 percent and 5.0 percent, respectively. The
1993 weighted average expected long-term rate of return on plan assets was 9.0
percent. The 1992 weighted average discount rate and rate of increase in future
compensation levels used in determining the actuarial present value of the
projected benefit obligation were 8.5 percent and 5.0 percent, respectively. The
1992 weighted average expected long-term rate of return on plan assets was 9.0
percent. Contributions to the plans are limited to amounts currently deductible
for tax purposes. The accumulated vested benefit obligation is the actuarial
present value of the vested benefits to which the employee is currently
entitled, but it is based on the employee's expected date of termination.
 
10.  POSTRETIREMENT AND POSTEMPLOYMENT BENEFITS OTHER THAN PENSIONS
 
     The Financial Accounting Standards Board issued SFAS 106 requiring
companies to account for OPEBs, (principally retiree medical costs) on an
accrual basis versus the pay-as-you-go basis traditionally followed by most
United States companies. The Company adopted SFAS 106 effective January 1, 1993.
 
     The Company provides a non-contributory defined benefit postretirement
medical plan that covers employees who retired on or before March 1, 1986 and
limited postretirement life insurance for employees who retire after January 1,
1985. As such, the Company's obligation to accrue for OPEBs is primarily limited
to the fixed population of retirees who retired on or before March 1, 1986. The
medical plan is funded to the extent employer contributions are recoverable
through rates.

     EPG began recovering through its rates the OPEB costs included in the
settlement agreement. To the extent actual OPEB costs exceed the amounts
reflected in the settlement agreement, a regulatory asset has been recorded.
Management expects such amounts to be fully recovered through its rates.

     A 13.5 percent annual rate of increase in the per capita costs of covered
health care benefits was assumed for 1994, gradually decreasing to 6 percent by
the year 2002. Increasing the assumed health care cost trend rates by one
percentage point in each year would increase the accumulated postretirement
benefit obligation as of December 31, 1993 by approximately $13.9 million and
increase the interest cost components of net periodic postretirement benefit
cost for 1993 by approximately $1 million. A discount rate of 7.5 percent was
used to determine the accumulated postretirement benefit obligation.
 
     The Financial Accounting Standards Board issued SFAS 112 which requires
companies to account for benefits to former or inactive employees after
employment but before retirement (referred to in SFAS 112 as "postemployment
benefits"). SFAS 112 is effective for the fiscal years beginning after December
15, 1993. Postemployment benefits include every form of benefit provided to
former or inactive employees, their beneficiaries and covered dependents.
Benefits include, but are not limited to salary continuation, supplemental
unemployment benefits, severance benefits, disability-related benefits
(including workers' compensation), job training and counseling, and continuation
of benefits such as health care benefits and life insurance coverage. The
cumulative effect at January 1, 1994 of adopting SFAS 112 is estimated to be
approximately $8 million. Management expects to fully recover its postemployment
benefits costs through rates.

14.  RELATED PARTY TRANSACTIONS
 
     In 1991 and for the first six months of 1992, BR and Meridian were
considered related parties of EPG. Through February 1992, EPG participated in an
intercorporate cash management arrangement with BR, pursuant to which excess
cash balances from each of BR's operating subsidiaries were advanced to BR on a
daily basis and cash requirements of BR's operating subsidiaries were funded
daily through advances from BR. Balances under the arrangement accrued interest
at rates approximating short-term market rates. In January and February 1992,
EPG declared and paid dividends totaling $274 million to BR from the balance
owed to EPG under the intercorporate cash management arrangement.
 
     On April 8, 1992, EPG's Board of Directors declared a quarterly dividend on
common stock of $0.25 per share to the June 1, 1992 stockholders of record. EPG
paid the dividend on June 19, 1992, in the amount of $9.3 million, $8 million of
which was paid to BR.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
     Revenues associated with the transportation of gas for Meridian by EPG were
$15 million for the six months ended June 30, 1992, and $47 million for the year
ended December 31, 1991.
 
     Operating revenues include $26 million related to transactions with the
discontinued Oil and Gas Operations Segment in 1991. Operating charges related
to transactions with the discontinued segment were less than $1 million in 1991.
In May 1991, EPG declared and paid a dividend to TEPCO of $175 million and in
December 1991 declared and paid a $55 million dividend to BR.
 
     Certain BR corporate overhead expenses were allocated to EPG. The allocated
amounts were not material and management believes the allocation methodology was
appropriate.
 
15.  FINANCIAL INSTRUMENTS
 
  Fair Value
 
     The following disclosure of the estimated fair value of financial
instruments was made in accordance with the requirements of Statement of
Financial Accounting Standards No. 107 ("SFAS 107"). The estimated fair value
amounts have been determined by the Company using available market information
and valuation methodologies.
 
     As of December 31, 1993, the carrying amounts of the various financial
instruments employed by the Company, including cash, cash equivalents,
short-term borrowings, and trade receivables and payables are representative of
fair value because of the short maturity of these instruments. The carrying
amounts and estimated fair values of the Company's other financial instruments
at December 31, 1993 are as follows:

</TABLE>
 
     The fair value of the Company's long-term debt has been estimated based on
quoted market prices for the same or similar issues. The fair value of interest
rate swap agreements is the amount at which they could be settled, based on
estimates obtained from dealers.
 
  Off-Balance Sheet Risk
 
     During 1993, EPG and EPGM entered into certain price swap agreements to, in
effect, hedge the market risk caused by fluctuations in the price of natural
gas. The agreements call for EPG and EPGM to make payments to or receive
payments from the other parties based upon the differential between a fixed and
a variable price for natural gas as specified by the contract. The current price
swap agreements run for periods of up to five years and had a notional contract
amount of approximately $30 million at December 31, 1993. While EPG and EPGM's
notional contract amounts are used to express the magnitude of price swap
agreements, the amounts potentially subject to credit risk, in the event of
non-performance by the other parties, are substantially smaller. EPG and EPGM do
not anticipate non-performance by the other parties.
 
     MPC has entered into interest rate swap agreements which effectively
convert $114.3 million of floating-rate debt to fixed-rate debt. MPC makes
payments to counterparties at fixed rates and in return receives payments at
floating rates.

to such notice, whether before or after the time stated therein, shall be
deemed equivalent to the giving of such notice.

       4.3.2.  The attendance of a stockholder at a meeting shall constitute a
waiver of notice of such meeting, except when a stockholder attends a meeting
for the express purpose of objecting, at the beginning of the meeting, to the
transaction of any business because the meeting is not lawfully called or
convened.

SECTION 5.  Fixing of Record Date for Determining Stockholders.

       5.1  Meetings.  For the purpose of determining stockholders entitled to
notice of or to vote at any meeting of stockholders or any adjournment thereof,
the Board may fix a record date, which record date shall not precede the date
upon which the resolution fixing the record date is adopted by the Board, and
which record date shall not be more than sixty nor less than ten days before
the date of such meeting.  If no record date is fixed by the Board, the record
date for determining stockholders shall be at the close of business on the day
next preceding the day on which notice is given, or, if notice is waived, at
the close of business on the day next preceding the day on which the meeting is
held.  A determination of stockholders of record entitled to notice of or to
vote at the meeting of stockholders shall apply to any adjournment of the
meeting; provided, however, that the Board may fix a new record date for the

        5.2 Dividends, Distributions and Other Rights.  For the purpose of
determining stockholders entitled to receive payment of any dividend or other
distribution or allotment of any rights or the stockholders entitled to
exercise any rights in respect of any change, conversion or exchange of stock,
or for the purpose of any other lawful action, the Board may fix a record date,
which record date shall not precede the date upon which the resolution fixing
the record date is adopted, and which record date shall be not more than sixty
days prior to such action.  If no record date is fixed, the record date for
determining stockholders for any such purpose shall be at the close of business
on the day on which the Board adopts the resolution relating thereto.

        SECTION 6.  Quorum.

        A majority of the outstanding shares of stock of the corporation
entitled to vote,  present in person or represented by proxy, shall constitute
a quorum at a meeting of the stockholders; provided that where a separate vote
by a class or classes or by a series of a class is required, a majority of the
outstanding shares of such class or classes or of such series of a class,
present in person or represented by proxy at the meeting, shall constitute a
quorum entitled to take action with respect to the vote on that matter. Shares
of stock will be counted toward a quorum if they are either (i) present in
person at the meeting or (ii) represented at the meeting by a valid proxy,
whether the instrument granting such proxy is marked as casting a vote or
abstaining, is left blank or does not empower such proxy to vote with respect
to some or all matters to be voted upon at the meeting.  If less than a
majority of the outstanding shares entitled to vote are represented at a
meeting, a majority of the shares so represented may adjourn the meeting from
time to time without further notice.  If a quorum is present or represented at
a reconvened meeting following such an adjournment, any business may be
transacted that might have been transacted at the meeting as originally called.
The stockholders present at a duly organized meeting may continue to
transact business until adjournment, notwithstanding the withdrawal of enough
stockholders to leave less than a quorum.

SECTION 7.  Organization.

        At each meeting of the stockholders, the Chairman of the Board, or in
his absence the President and Chief Executive Officer or, if both of the said
officers are absent, a person designated by the Board, the Chairman of the
Board or the President and Chief Executive Officer, or in the absence of such
designated person, a person elected by the holders of a majority in number of
shares of stock present in person or represented by proxy and entitled to vote,
shall act as chairman of the meeting.

        The Secretary, or in his absence or in the event he shall be presiding
over the meeting in accordance with the provisions of this Section, an
Assistant Secretary or, in the absence of the Secretary and all of the
Assistant Secretaries, any person appointed by the chairman of the meeting,
shall act as secretary of the meeting.

SECTION 8.  Voting.

       8.1  General Provisions.  Unless otherwise provided in the Restated
Certificate of Incorporation or a resolution of the Board creating a series of
stock, at each meeting of the stockholders, each holder of any share of any
series or class of stock entitled to vote at such meeting shall be entitled to
one vote for each share of stock having voting power in respect of each matter
upon which a vote is to be taken, standing in his name on the stock ledger of
the corporation on the record date fixed as provided in these By-laws for
determining the stockholders entitled to vote at such meeting.   In all
matters other than the election of Directors, if a quorum is present, the
affirmative vote of the majority of the shares present in person or represented
by proxy at the meeting and entitled to vote on the subject matter shall be the
act of the stockholders, unless the vote of a greater number is required by
these By-laws, the Restated Certificate of Incorporation or the General
Corporation Law of the State of Delaware.  In determining the number of votes
cast for or against a proposal, shares abstaining from voting on a matter
(including elections) will not be treated as a vote for or against the
proposal.  A non-vote by a broker will be treated as if the broker never voted,
but a non-vote by a stockholder will be counted as a vote "for" the
management's position.  Where a separate vote by a class or classes or by a
series of a class is required, if a quorum is present, the affirmative vote of
the majority of shares of such class or classes or series of a class present in
person or represented by proxy at the meeting shall be the act of such class or
classes or series of a class. The provisions of this Section will govern with
respect to all votes of stockholders except as otherwise provided for in these
By-laws, the Restated Certificate of Incorporation or the General Corporation
Law of the State of Delaware.

       8.2 Voting for Directors.  At each election of Directors the voting
shall be by written ballot.  Directors shall be elected by a plurality of the
votes of the shares present in person or represented by proxy at the meeting
and entitled to vote on the election of Directors.

       8.3 Shares Held or Controlled by the Corporation.  Shares of its own
capital stock belonging to the corporation, or to another corporation if a
majority of the shares entitled to vote in the election of Directors of such
other corporation is held by the corporation, shall neither be entitled to
vote nor counted for quorum purposes.

       8.4 Proxies.  A stockholder may vote by proxy executed in writing by the
stockholder or by his attorney-in-fact.  Such proxy shall be filed with the
Secretary of the corporation before or at the time of the meeting.  A
stockholder may revoke any proxy which is not irrevocable by attending the
meeting and voting in person or by filing an instrument in revoking the proxy
or another duly executed proxy bearing a later date with the Secretary of the
corporation.  A proxy shall become invalid three years after the date of its
execution, unless otherwise provided in the proxy.  A proxy with respect to a
specified meeting shall entitle the holder thereof to vote at any reconvened
meeting following adjournment of such meeting but shall not be valid after the
final adjournment thereof.



                                     - 4 -

       SECTION 9. Inspectors.

       Prior to each meeting of stockholders, the Board shall appoint two
Inspectors who are not Directors, candidates for Directors or officers of the
corporation, who shall receive and determine the validity of proxies and the
qualifications of voters, and receive, inspect, count and report to the meeting
in writing the votes cast on all matters submitted to a vote at such meeting.
In case of failure of the Board to make such appointments or in case of failure
of any Inspector so appointed to act, the Chairman of the Board shall make such
appointment or fill such vacancies. Each Inspector, immediately before entering
upon his duties, shall subscribe to an oath or affirmation faithfully to
execute the duties of Inspector at such meeting with strict impartiality and
according to the best of his ability.

       SECTION 10. List Of Stockholders.

      The Secretary or other officer or agent having charge of the stock ledger
of the corporation shall prepare and make, at least ten days before every
meeting of stockholders, a complete list of the stockholders entitled to vote
at said meeting, arranged in alphabetical order and showing the address of each
stockholder and the number of shares of each class and series registered in the
name of each such stockholder. Such list shall be open to the examination of
any stockholder, for any purpose germane to the meeting, during ordinary
business hours, for a period of at least ten days prior to the meeting, either
at a place within the city where the meeting is to be held, which place shall
be specified in the notice of the meeting, or, if not so specified, at the
place where the meeting is to be held. Such list shall also be produced and
kept at the time and place of the meeting during the whole time thereof, and
may be inspected by any stockholder who is present. The stock ledger shall be
the only evidence as to who are the stockholders entitled to examine the stock
ledger, the list required by this section, or the books of the corporation, or
to vote in person or by proxy at any such meeting.

      SECTION 11. Stockholder Proposals.

      Stockholder proposals for inclusion in any proxy statement to be issued
in connection with the annual meeting of stockholders must be mailed to the
Corporate Secretary, El Paso Natural Gas Company, P.O. Box 1492, El Paso, Texas
79978, and must be received by the Corporate Secretary at least by the 150th

for stockholder proposals is set forth in the corporation's proxy statement.

<PAGE>   9
shall from time to time by a vote of a majority of the Directors then in office
fix the specific number of Directors to constitute the Board. At each annual
meeting of stockholders a Board shall be elected by the stockholders for a term
of one year. Each Director shall serve until his successor is duly elected and
shall qualify.

      SECTION 2. Vacancies.

      Vacancies in the Board and newly created directorships resulting from any
increase in the authorized number of Directors may be filled by a vote of the
majority of the Directors then in office, although less than a quorum, or by a
sole remaining Director, at any regular or special meeting of the Board.

      SECTION 3. Resignations.

      Any Director may resign at any time upon written notice to the Board, the
Chairman of the Board, the President and Chief Executive Officer or the
Secretary of the corporation. Such resignation shall take effect on the date of
receipt of such notice or at any later time specified therein; and the
acceptance of such resignation, unless otherwise required by the terms thereof,
shall not be necessary to make it effective. When one or more Directors shall
resign effective at a future date, a majority of the Directors then in office,
including those who have resigned, shall have power to fill such vacancy or
vacancies to take effect when such resignation or resignations shall become
effective.

      SECTION 4. Removals.

      Any Director may be removed, with or without cause, at any special
meeting of the stockholders called for that purpose, by the affirmative vote of
the holders of a majority in number of shares of the corporation entitled to
vote for the election of such Director, and the vacancy in the Board caused by
any such removal may be filled by the stockholders at such a meeting.

      SECTION 5. Place of Meetings; Books and Records.

      The Board may hold its meetings, and have an office or offices, at such
place or places within or without the State of Delaware as the Board from time
to time may determine.

      The Board, subject to the provisions of applicable statutes, may
authorize the books and records of the corporation, and offices or agencies for
the issue, transfer and registration of the capital stock of the corporation,
to be kept at such place or places outside of the State of Delaware as, from
time to time, may be designated by the Board.

      SECTION 6. Annual Meeting of the Board.

      The first meeting of each newly elected Board, to be known as the Annual
Meeting of the Board, for the purpose of electing officers, designating
committees and the transaction of such other business as may come before the
Board, shall be held as soon as practicable after the

                                    - 6 -
<PAGE>   10
adjournment of the annual meeting of stockholders, and no notice of such
meeting shall be necessary to the newly elected Directors, provided a quorum
shall be present. In the event such meeting is not held due to the absence of a
quorum, the meeting may be held at such time and place as shall be specified in
a notice given as hereinafter provided for special meetings of the Board, or as
shall be specified in a written waiver signed by all of the newly elected
Directors.

      SECTION 7. REGULAR MEETINGS.

person or persons calling the meeting shall deem appropriate in the
circumstances. Notice of each such special meeting shall be mailed to each
Director or delivered to him by telephone, telegraph or any other means of
electronic communication, in each case addressed to his residence or usual
place of business, or delivered to him in person or given to him orally. The
notice of meeting shall state the time and place of the meeting but need not
state the purpose thereof. Whenever any notice is required to be given to any
Director under the provisions of these By-laws, the Restated Certificate of
Incorporation or the General Corporation Law of the State of Delaware, a waiver
thereof in writing, signed by the person or persons entitled to such notice,
whether before or after the time stated therein, shall be deemed equivalent to
the giving of such notice. Neither the business to be transacted at, nor the
purpose of, any regular or special meeting of the Board or any committee
appointed by the Board need be specified in the waiver of notice of such
meeting. Attendance of a Director at any meeting shall constitute a waiver of
notice of such meeting except when a Director attends a meeting for the express
purpose of objecting to the transaction of any business because the meeting was
not lawfully called or convened.

      SECTION 9. Quorum and Manner of Acting.

      Except as otherwise provided by statute, the Restated Certificate of
Incorporation, or these By-laws, the presence of a majority of the total number
of Directors shall constitute a quorum for the transaction of business at any
regular or special meeting of the Board, and the act of a majority of the
Directors present at any such meeting at which a quorum is present shall be the
act of the Board. In the absence of a quorum, a majority of the Directors
present may adjourn the meeting, from time to time, until a quorum is present.
Notice of any such adjourned meeting need not be given.

      SECTION 10. Organization.

      At every meeting of the Board, the Chairman of the Board or in his
absence the President and Chief Executive Officer or, if both of the said

                                    - 7 -
<PAGE>   11
officers are absent, a chairman chosen by a majority of the Directors present
shall act as chairman of the meeting. The Secretary, or in his absence, an
Assistant Secretary, or in the absence of the Secretary and all the Assistant
Secretaries, any person appointed by the chairman of the meeting, shall act as
secretary of the meeting.

      SECTION 11. Consent of Directors in Lieu of Meeting.

      Unless otherwise restricted by the Restated Certificate of Incorporation
or by these By-laws, any action required or permitted to be taken at any
meeting of the Board, or any committee designated by the Board, may be taken
without a meeting if all members of the Board or committee consent thereto in
writing, and such written consent is flied with the minutes of the proceedings
of the Board or committee.

      SECTION 12. Telephonic Meetings.

      Members of the Board, or any committee designated by the Board, may
participate in any meeting of the Board or committee by means of conference
telephone or similar communications equipment by means of which all persons
participating in the meeting can hear each other, and participation in such a
meeting shall constitute presence in person at such meeting.

      SECTION 13. Compensation.

      Each Director, who is not a full-time salaried officer of the corporation
or any of its wholly owned subsidiaries, when authorized by resolution of the
Board, may receive as a Director a stated salary or an annual retainer, and any
other benefits as the Board may determine, and in addition may be allowed a
fixed fee or reimbursement of his reasonable expenses for attendance at each
regular or special meeting of the Board or any committee thereof.

      SECTION 14. Interested Directors.

      No contract or transaction between the corporation and one or more of its
Directors or officers, or between the corporation and any other corporation,
partnership, association or other organization in which one or more of its
Directors or officers are Directors or officers of this corporation, or have a
financial interest in such contract or transaction, shall be void or voidable
solely for this reason, or solely because the Director or officer is present at
or participates in the meeting of the Board or committee thereof which
authorizes the contract or transaction, or solely because his or their votes
are counted for such purpose, if: (1) the material facts as to his relationship
or interest and as to the contract or transaction are disclosed or are known to
the Board or the committee, and the Board or committee in good faith authorizes
the contract or transaction by the affirmative votes of a majority of the
disinterested Directors, even though the disinterested Directors be less than a
quorum; or (2) the material facts as to his relationship or interest and as to
the contract or transaction are disclosed or are known to the stockholders
entitled to vote thereon, and the contract or transaction is specifically
approved in good faith by

                                    - 8 -
<PAGE>   12
vote of the stockholders; or (3) the contract or transaction is fair as to the
corporation as of the time it is authorized, approved or ratified by the Board,
a committee thereof or the stockholders.  Common or interested Directors may be
counted in determining the presence of a quorum at a meeting of the Board or of
a committee which authorizes the contract or transaction.

          (g)   To approve in emergency situations commitments in excess of the
     above-described limits provided they are in the interests of the

                                  ARTICLE VIII

                                INDEMNIFICATION

      SECTION 1.  Right to Indemnification.

      Each person who was or is made a party or is threatened to be made a
party to or is involved (including, without limitation, as a witness) in





                                      -17-

<PAGE>   21





any actual or threatened action, suit or proceeding, whether civil, criminal,
administrative or investigative (hereinafter a "proceeding"), by reason of the
fact that he is or was a Director, officer or employee of the corporation or
is or was serving at the request of the corporation as a Director, officer,
employee or agent of another corporation or of a partnership, joint venture,
trust or other enterprise, including service, with respect to an employee
benefit plan (hereinafter an "indemnitee"), whether the basis of such
proceeding is alleged action in an official capacity as a Director, officer,
employee or agent or in any other capacity while serving as such a Director,
officer, employee or agent, shall be indemnified and held harmless by the
corporation to the full extent authorized by the General Corporation Law of
the State of Delaware, as the same exists or may hereafter be amended (but, in
the case of any such amendment, only to the extent that such amendment permits
the corporation to provide broader indemnification rights than said law
permitted the corporation to provide prior to such amendment), or by other
applicable law as then in effect, against all expense, liability and loss
(including attorneys' fees, judgments, fines, ERISA excise taxes or penalties
and amounts to be paid in settlement) actually and reasonably incurred or
suffered by such indemnitee in connection therewith and such indemnification
shall continue as to an indemnitee who has ceased to be a Director, officer,
employee or agent and shall inure to the benefit of the indemnitee's heirs,
executors and administrators; provided, however, that except as provided in
Section 2 of this Article with respect to proceedings seeking to enforce
rights to indemnification, the corporation shall indemnify any such indemnitee
seeking indemnification in connection with a proceeding (or part thereof)
initiated by such indemnitee only if such proceeding (or part thereof) was
authorized by the Board of the corporation. The right to indemnification
conferred in this Section shall be a contract right and shall include the
right to be paid by the corporation the expenses incurred in defending any
such proceeding in advance of its final disposition (hereinafter an
"advancement of expenses"); further provided, however, that, if the General
Corporation Law of the State of Delaware requires, an advancement of expenses
incurred by an indemnitee in his capacity as a Director, officer or employee
(and not in any other capacity in which service was or is rendered by such
indemnitee while a Director, officer or employee, including, without
limitation, service to an employee benefit plan) shall be made only upon
delivery to the corporation of an undertaking, by or on behalf of such
indemnitee, to repay all amounts so advanced if it shall ultimately be
determined that such indemnitee is not entitled to be indemnified under this
Section 1, or otherwise.

      SECTION 2.  Right of Indemnitee to Bring Suit.

      If a claim under Section 1 of this Article is not paid in full by the
corporation within sixty days after a written claim has been received by the
corporation, except in the case of a claim for an advancement of expenses, in
which case the applicable period shall be twenty days, the indemnitee may at
any time thereafter bring suit against the corporation to recover the unpaid
amount of the claim and, to the extent successful in whole or in part, the
indemnitee shall be entitled to be paid also the expense of prosecuting such
suit. The indemnitee shall be presumed to be





                                      -18-

<PAGE>   22





entitled to indemnification under this Article upon submission of a written
claim (and, in an action brought to enforce a claim for an advancement of
expenses, where the required undertaking, if any is required, has been
tendered to the corporation), and thereafter the corporation shall have the
burden of proof to overcome the presumption that the indemnitee is not so
entitled.  Neither the failure of the corporation (including its Board,
independent legal counsel, or its stockholders), to have made a determination
prior to the commencement of such suit that indemnification of the indemnitee
is proper in the circumstances, nor an actual determination by the corporation
(including its Board, independent legal counsel or its stockholders) that the
indemnitee is not entitled to indemnification, shall be a defense to the suit
or create a presumption that the indemnitee is not so entitled.

      SECTION 3.  Nonexclusivity of Rights.

      The rights to indemnification and to the advancement of expenses
conferred in the Article shall not be exclusive of any other right which any
person may have or hereafter acquire under any statute, provision of the
Restated Certificate of Incorporation, By-law, agreement, vote of stockholders
or disinterested Directors or otherwise.

      SECTION 4.  Insurance, Contracts and Funding.

      The corporation may maintain insurance, at its expense, to protect
itself and any Director, officer, employee or agent of the corporation or
another corporation, partnership, joint venture, trust or other enterprise
against any expense, liability or loss, whether or not the corporation would
have the power to indemnify such person against such expense, liability or
loss under the General Corporation Law of the State of Delaware. The
corporation may enter into contracts with any indemnitee in furtherance of the
provisions of this Article and may create a trust fund, grant a security
interest or use other means (including, without limitation, a letter of
credit) to ensure the payment of such amounts as may be necessary to effect
indemnification as provided in this Article.

      SECTION 5.  Wholly Owned Subsidiaries.

      Any person who is or was serving as a Director of a wholly owned
subsidiary of the corporation shall be deemed, for purposes of this Article
only, to be a Director, officer or employee of the corporation entitled to
indemnification under this Article.

      SECTION 6.  Indemnification of Agents of the Corporation.

      The corporation may, by action of the Board from time to time, grant
rights to indemnification and advancement of expenses to agents of the
corporation with the same scope and effect as the provisions of this Article
with respect to the indemnification and advancement of expenses of Directors,
officers and employees of the corporation.

         SECTION 1. Checks, Drafts, Etc.: Loans.

         All checks, drafts, or other orders for the payment of money, notes or
other evidences of indebtedness issued in the name of the corporation shall be
signed by such officer or officers, agent or agents of the corporation and in
such manner as shall, from time to time, be determined by resolution of the
Board.  No loans shall be contracted on behalf of the corporation unless

circumstances.

         SECTION 2.  Deposits.

         All funds of the corporation shall be deposited, from time to time, to
the credit of the corporation in such banks, trust companies or other
depositories as the Board may select, or as may be selected by any officer or
officers, agent or agents of the corporation to whom such power may, from time
to time, be delegated by the Board; and, for the purpose of such deposit, the
President and Chief Executive Officer, any Executive Vice President, any Senior
Vice President, any Vice President, the Treasurer or any Assistant Treasurer,
or any other officer or agent to whom such power may be delegated by the Board,
may endorse, assign and deliver checks, drafts and other order for the payment
of money which are payable to the order of the corporation.

                                  ARTICLE XII

                                   AMENDMENTS

         These By-laws may be altered or repeated and new By-laws may be made
by the affirmative vote, at any meeting of the Board, of a majority of the
entire Board, subject to the rights of the stockholders of the corporation to
amend or repeal By-laws made or amended by the Board by the affirmative vote of
the holders of record of a majority in number of shares of the outstanding
stock of the corporation present or represented at any meeting of the
stockholders and entitled to vote thereon, provided that notice of the proposed
action be included in the notice of such meeting.

                                  ARTICLE XIII

                                 MISCELLANEOUS

         All references and uses herein of the masculine pronouns "he" or "his"
shall have equal applicability to and shall also mean their feminine 
counterpart pronouns, such as "she" or "her."
