ITEM 1. BUSINESS
 
GENERAL
 
     Apache Corporation (Apache or the Company), a Delaware corporation formed
in 1954, is an independent energy company that explores for, develops and
produces natural gas, crude oil and natural gas liquids. In North America,
Apache's exploration and production interests are focused on the Gulf of Mexico,
the Anadarko Basin, the Permian Basin, the Gulf Coast and the Western
Sedimentary Basin of Canada. Outside of North America, Apache has exploration
and production interests offshore Western Australia and in Egypt, and
exploration interests in Indonesia, offshore The People's Republic of China and
offshore the Ivory Coast. Apache common stock, par value $1.25 per share, has
been listed on the New York Stock Exchange since 1969, and on the Chicago Stock
Exchange since 1960.
 
     Apache holds interests in many of its U.S., Canadian and international
properties through operating subsidiaries, such as MW Petroleum Corporation
(MW), Apache Canada Ltd., DEK Energy Company (DEKALB, formerly known as DEKALB
Energy Company), Apache Energy Limited (AEL, formerly known as Hadson Energy
Limited), Apache International, Inc., Apache Overseas, Inc. and The Phoenix
Resource Companies, Inc. Properties referred to in this document may be held by
those subsidiaries. Apache treats all operations as one segment of business.
 
1996 RESULTS
 
     In 1996, Apache had net income of $121.4 million, or $1.42 per share, on
total revenues of $977.2 million. Net cash provided by operating activities
during 1996 was $490.5 million.
 
     The year 1996 was Apache's 19th consecutive year of production growth and
ninth consecutive year of oil and gas reserves growth. Apache's average daily
production was 53.2 Mbbls of oil and 561 MMcf of natural gas for the year.
Giving effect to 1996 acquisitions, dispositions and drilling activity, the
Company's estimated proved reserves increased by 85.6 MMboe in 1996 over the
prior year to 506.2 MMboe, of which approximately 54 percent of total reserves
was natural gas. Based on 420.6 MMboe reported at year-end 1995, Apache's
reserve growth during the year reflects replacement of 257 percent of the
Company's 1996 production, including approximately 179 percent through drilling,
revisions, recompletions, workovers and other production enhancement projects.
Apache's active drilling and production-enhancement program yielded 279 new
producing U.S. and Canadian wells out of 370 attempts and involved 344 major
North American workover and recompletion projects during the year.
 
     At December 31, 1996, Apache had interests in approximately 4,564 net oil
and gas wells and 1,523,405 net developed acres of oil and gas properties. In
addition, the Company had approximately 791,627 net undeveloped acres under U.S.
and Canadian leases and 6,881,900 net undeveloped acres under international
exploration and production rights.
 
APACHE'S GROWTH STRATEGY
 
     Apache's growth strategy is to increase oil and gas reserves, production,
and cash flow through a combination of exploratory drilling, development of its
inventory of existing projects and, principally in North America, tactical
acquisitions meeting defined financial parameters. The Company's drilling
program emphasizes reserve additions through exploratory drilling primarily on
its international interests, and moderate-risk drilling primarily on its North
American interests. The Company also emphasizes reducing operating costs per
unit produced and selling marginal and non-strategic properties in order to
increase its profit margins.
 
     Apache's international investments and exploration activities are an
important component of its long-term growth strategy. Although international
exploration is recognized as higher-risk than most of Apache's U.S. and Canadian
activities, it offers potential for greater rewards and significant reserve
additions. Apache directed its international efforts in 1996 toward development
of certain discoveries offshore Western Australia
 
                                        1
<PAGE>   4
 
and in Egypt, and toward further exploration efforts on its concessions in
Egypt, offshore The People's Republic of China, in Indonesia, and offshore the
Ivory Coast of western Africa. Apache believes that reserve additions in these
international areas may be made through higher-risk exploration and through
improved production practices and recovery techniques.
 
     For Apache, property acquisition is only one phase in a continuing cycle of
business growth. Apache's aim is to follow each acquisition with a cycle of
reserve enhancement, property consolidation and cash flow acceleration,
facilitating asset growth and debt reduction. This approach requires a
well-planned and carefully executed property development program and, where
appropriate, a selective program of property dispositions. It motivates Apache
to target acquisitions that have ascertainable additional reserve potential and
to apply an active drilling, workover and recompletion program to realize the
potential of the acquired undeveloped and partially developed properties. Apache
prefers to operate its properties so that it can best influence their
development; as a result, the Company operates properties accounting for over 75
percent of its production.
 
1996 ACQUISITIONS AND DISPOSITIONS
 
     The Company entered into the Agreement and Plan of Merger dated March 27,
1996 (the Merger Agreement) with The Phoenix Resource Companies, Inc. (Phoenix),
providing for a merger in which Phoenix would become a wholly owned subsidiary
of the Company (the Merger). On May 20, 1996, the transaction was approved by
the Phoenix shareholders and the Merger was consummated. Pursuant to the Merger
Agreement, each of the 16.2 million shares of Phoenix common stock then
outstanding was converted into the right to receive .75 shares of Apache common
stock, with any fractional shares paid in cash, without interest, and $4.00 in
cash, resulting in a total of 12.2 million shares of Apache common stock being
issued and approximately $65 million being paid in respect of the Phoenix common
stock.
 
     Phoenix's principal assets are its interest in the Khalda and Qarun oil and
gas concessions located in the Western Desert of Egypt, which in the aggregate
contain 18 oil fields and six gas fields. Phoenix's oil and gas operations are
currently conducted through Egyptian operating companies owned jointly by the
Egyptian General Petroleum Corporation (EGPC), Phoenix and certain other
participants, including the Company in the Qarun concession. In conjunction with
the Merger, George D. Lawrence Jr., former president and chief executive officer
of Phoenix, joined Apache's board of directors.
 
     During 1996, Apache also acquired oil and gas properties and seismic data
in North America and Egypt in transactions whose purchase prices totaled
approximately $115 million, the most significant of which was the purchase of
interests in offshore blocks in the Gulf of Mexico from Hall-Houston Oil Company
(Hall-Houston) and related entities in August for approximately $46 million. In
1996, Apache also disposed of oil and gas properties and gas plants in
transactions whose sales proceeds totaled approximately $30.1 million. In
addition, Apache monetized certain gas properties entitled to Internal Revenue
Code Section 29 Tax Credits in two transactions with the Apache Series 1996-A
Trust, whose managing trustee is Apache and whose non-managing trustee is FC
Energy Finance I, Inc. Total net proceeds from these two transactions were
approximately $23 million.
 
EXPLORATION AND PRODUCTION
 
     The Company's North American exploration and production activities are
divided into five operating regions Offshore, Midcontinent, Western, Gulf Coast
and Canadian regions. Approximately 82 percent of the Company's proved reserves
are located in the five North American regions. Following the Phoenix Merger,
Egypt became an important region for Apache. The Company's Egyptian operations
are headquartered in Cairo. Apache conducts its Australian exploration and
production and its Indonesian exploration through its Australian region.
Information concerning the amount of revenue, operating income and identifiable
assets attributable to U.S., Canadian and international operations,
respectively, is set forth in the Supplemental Oil and Gas Disclosures under
Item 8 below.
 
     Offshore. The Offshore region (referred to as the Gulf of Mexico region in
1995) includes all of Apache's interests in properties offshore Texas, Louisiana
and Alabama. In 1996, Offshore produced approximately 11.8 MMboe and $181
million in production revenue for the year. At December 31, 1996, the
 
                                        2
<PAGE>   5
 
Offshore region held 346,806 net acres, located in both state and federal
waters, and accounted for 45.8 MMboe, or nine percent, of the Company's year-end
1996 total estimated proved reserves. Apache's operations in the Offshore region
focused on workovers and recompletions, which totaled 33 in the region for 1996.
Apache participated in 19 wells which were drilled in the region during the
year, 10 of which were completed as producers. For 1996, Apache's gas production
from the Offshore region was approximately 61,554 MMcf.
 
     Midcontinent. Apache's Midcontinent region operates in Oklahoma, eastern
Texas and northern Louisiana. The region has focused operations on its sizable
position in the Anadarko Basin of western Oklahoma. Apache has drilled and
operated in the Anadarko Basin for nearly four decades, developing an extensive
database of geologic information and a substantial acreage position. The
Midcontinent region produced approximately 12 MMboe for the year, creating $167
million in production revenue for the Company.
 
     At December 31, 1996 Apache held an interest in 409,033 net acres in the
region, which accounted for approximately 106.5 MMboe, or 21 percent, of
Apache's total estimated proved reserves. Apache participated in drilling 103
wells in the Midcontinent region during the year, 85 of which were completed as
producing wells. The Company performed 26 major workover and recompletion
operations in the region during 1996.
 
     Western. The Western region includes assets in the Permian Basin of western
Texas and New Mexico, the Green River Basin of Colorado and Wyoming and the San
Juan Basin of New Mexico. The Western region was Apache's leading region for oil
and gas sales for 1996, producing approximately 10.4 MMboe and $185 million in
oil and gas revenue, 22 percent of the Company's production revenues during
1996. At December 31, 1996, the Company held 649,820 net acres in the region,
which accounted for 137.4 MMboe, or 27 percent, of the Company's total estimated
proved reserves. Apache participated in drilling 128 wells in the Western
region, 103 of which were productive wells. Apache performed 30 major workovers
and recompletions in the Western region during the year.
 
     Gulf Coast. The Gulf Coast region encompasses the Texas and Louisiana
coasts, central Texas and Mississippi. In 1996, the Gulf Coast region
contributed approximately $182 million in revenues from production of 9.9 MMboe
for the year. The region was one of the most active in the Company in the number
of workover and recompletion projects completed and the number of wells drilled.
The Company performed 226 major workover and recompletion operations during 1996
in the Gulf Coast region and participated in drilling 43 wells, 31 of which were
completed as producers. As of December 31, 1996, the region encompassed 273,568
net acres, and accounted for 69.5 MMboe, or 14 percent, of the Company's
year-end 1996 total estimated proved reserves.
 
     Canada. Exploration and development activity in the Canadian region is
concentrated in the Provinces of Alberta and British Columbia. The region
produced approximately 5.5 MMboe, 83 percent of which was natural gas, and
generated $48 million in oil, gas and natural gas liquids sales, six percent of
the Company's production revenues in 1996. Apache participated in drilling 77
wells in this region during the year, 50 of which were completed as producers.
The Company performed 29 workovers and recompletions on operated wells during
1996. At December 31, 1996, the region encompassed approximately 409,120 net
acres, and accounted for 57.1 MMboe, or 11 percent, of the Company's year-end
1996 total estimated proved reserves.
 
     Egypt. At year end, Apache held 6,051,867 net acres in Egypt, accounting
for 58.6 MMboe of estimated proved reserves or 12 percent of Apache's total
estimated proved reserves. As a result of the acquisition of Phoenix in May 1996
(see "1996 Acquisitions and Dispositions"), Apache owns a 75 percent interest in
the Qarun Block and a 40 percent interest in the Khalda Block, both in the
Western Desert of Egypt. At year end, the Qarun Block, which Apache operates,
consisted of approximately 1,927,000 acres, of which approximately 46,500 were
classified as developed. Currently, the Qarun Block is producing approximately
27,000 b/d from 13 wells, which is being sold to EGPC. The Khalda Block consists
of approximately 2,416,000 acres, of which approximately 318,500 were classified
as developed as of year end. The Khalda Block is currently producing
approximately 33,000 b/d from 78 wells, which is transported to market by
pipeline to a point west of Alexandria, Egypt. Future production of gas from
Khalda is expected to be delivered for sale to EGPC at a point west of
Alexandria, Egypt, via a 34-inch gas pipeline, construction of which is
scheduled to commence in
 
                                        3
<PAGE>   6
 
1997 and to be completed by 1999. The costs of building the pipeline will be
borne by Apache, the other Khalda participants and the owners of a neighboring
block. Construction costs paid by Apache and the other Khalda participants will
be recoverable from oil and gas production from the Khalda Block.
 
     Both the Khalda and Qarun Concession Agreements provide that Apache and its
partners in the concessions will pay all of the operating and capital costs for
developing the concessions, while the production will be split between EGPC and
the partners. Up to 40 percent of the oil and gas produced from each of the
concessions is available to the Company and its partners to recover operating
and capital costs for the applicable concession. To the extent eligible costs
exceed 40 percent of the oil and gas produced and sold from a concession in any
given quarter, such excess costs may be carried into future quarters without
limit. The remaining 60 percent of all oil and gas produced from the concessions
is divided between EGPC and Apache and its partners, with the percentage
received by Apache and its partners reducing as the gross daily average of oil
and gas produced on a quarterly basis increases. Under the Khalda Agreement,
capital costs are amortized over four years, while the Qarun agreement provides
for a five year amortization.
 
     In addition to the Qarun and Khalda Blocks, Apache holds a 50 percent
interest in 459,600 acres in the Darag Block in the northern Gulf of Suez, and a
50 percent interest in the 6,820,000 acre East Beni Suef Block immediately to
the south of the Qarun Block. Both the Darag and East Beni Suef Blocks are in
the early stages of evaluation, and exploratory drilling is expected to begin in
the latter part of 1997. In January 1997, Apache completed the purchase from
Mobil Exploration Egypt, Inc. of interests in three blocks in the Western Desert
of Egypt; a 24 percent interest in the 3,212,000-acre North East Abu Gharadig
Block, a 50 percent interest in the 1,384,000-acre East Bahariya Block, and a
one-third interest in the 3,100,000-acre West Mediterranean Block No. 1 (partly
onshore and partly offshore).
 
     Australia. Western Australia became an important region for Apache after
the 1993 acquisition of Hadson Energy Resources Corporation (subsequently known
as Apache Energy Resources Corporation or AERC). In 1996, the region generated
three percent of the Company's revenues for the year. Natural gas production in
the region increased by 45 percent from the prior year to approximately 13.9
MMcf/d in 1996. Average daily oil production decreased by 26 percent to
approximately 2,318 b/d in 1996, primarily as a result of natural depletion. As
of December 31, 1996, Apache held 64,410 net developed acres and 607,878 net
undeveloped acres in Western Australia. Apache acts as operator for most of its
properties in Western Australia through a wholly owned subsidiary, AEL.
 
     During 1996, Apache's estimated proved reserves in Australia increased by
60 percent to 31.3 MMboe, six percent of the Company's total estimated proved
reserves at year end. The increase in Australia reserves was primarily
attributable to natural gas reserves booked at the East Spar discovery which
were recorded only after the Company had entered into agreements for the sale
and delivery of such gas. Through AEL and its subsidiaries, Apache operates the
Harriet Gas Gathering Project, a gas processing and compression facility with a
throughput capacity of 100 MMcf/d, and a 60-mile, 12-inch offshore pipeline with
a throughput capacity of 175 MMcf/d. See "Oil and Natural Gas Marketing."
 
     Other International Operations. Outside of Canada, Egypt and Australia,
Apache currently has exploration interests in Indonesia, offshore The People's
Republic of China and offshore the Ivory Coast.
 
     In Indonesia, Apache holds a 39 percent interest in and operates the Bentu
Segat Block on Central Sumatra, on which an undeveloped gas field is located.
Negotiations with potential buyers for the gas are continuing.
 
     Apache is also the operator, with a 50 percent interest, of the Zhao Dong
Block in the Bohai Bay, offshore The People's Republic of China. In 1994 and
1995, discovery wells tested at rates between 1,300 and 4,000 b/d of oil. The
Company elected to proceed with the second exploration phase, commencing in May
1996, which involves a commitment to drill two additional exploratory wells. In
early 1997, a new well tested at rates up to 11,571 b/d of oil, and the Company
is currently evaluating the discovery areas for commercial potential. In March
1997, Apache gave XCL-China Ltd., which is the owner of the remaining 50 percent
interest in the Zhao Dong Block, default notices of nonpayment totaling
approximately $7.8 million (not including interest) owed on its share of joint
account expenses.

     In the Ivory Coast, Apache drilled an exploratory well in 1996 on the CI-27
offshore Block, confirming the existence of substantial reserves of gas in the
Foxtrot field and the produceability of some oil from the field's lower
horizons. Apache is the operator of the block, holding a 40 percent interest.
Discussions with potential gas buyers are taking place.
 
OIL AND NATURAL GAS MARKETING
 
     On October 27, 1995, wholly owned affiliates of each of Apache, Oryx Energy
Company and Parker & Parsley Petroleum Company formed Producers Energy
Marketing, LLC, a Delaware limited liability company (ProEnergy). ProEnergy
became fully operational on April 1, 1996, and markets substantially all of its
members' domestic natural gas pursuant to member gas purchase agreements having
an initial term of 10 years, subject to early termination following specified
events. The price of gas purchased by ProEnergy from its members is based upon
agreed to published indexes. ProEnergy also provides its members with certain
contract administration and other services.
 
     ProEnergy's limited liability company agreement provides that capital
funding obligations, allocations of profit and loss and voting rights are
calculated based upon the members' respective throughputs of natural gas sold to
ProEnergy. Each member's liability with respect to future capital funding
obligations is subject to certain limitations. Natural gas throughputs are
calculated, profit distributed, and/or capital called on a quarterly basis. As
of December 31, 1996, the Company held an approximate 44 percent interest in
ProEnergy.
 
     Apache is delivering natural gas under several long-term supply agreements
with terms greater than one-year. In connection with the acquisition of
substantially all of the oil and natural gas assets (the Aquila Assets) of
Aquila Energy Resources Corporation (Aquila) in September 1995, the Company
entered into a five-year, four-month premium-price gas contract under which
Aquila Energy Marketing Corporation agreed to purchase 20 to 25 MMcf of gas per
day from Apache at a price of $2.80 per Mcf in 1997, escalating to $3.20 per Mcf
in the year 2000. In December 1994, the Company signed a long-term gas contract
under which Apache received an advance payment of $67.4 million. Apache will
supply the purchaser with approximately 43 Bcf of gas over a six-year period
which began in January 1995, with volumes averaging 20 MMcf/d.
 
     Apache is also delivering natural gas under several such contracts with
various cogeneration facilities. One such agreement provides that Apache will
supply a minimum of 51.1 Bcf over 10 years for use in electric power generation
from a cogeneration facility located in northeast Texas. Under the agreement,
deliveries of approximately 20 MMcf/d began in early 1997. Another such
agreement, which expires at the end of September 2005, requires Apache to
deliver 20 MMcf/d to a cogeneration facility at a price escalating yearly. In
1996, the price under this agreement was $3.08 per MMcf. Apache is also a party
to an agreement that provides for delivery of up to 9.6 MMcf/d to a cogeneration
facility at a price that escalates yearly. As of the end of 1996, the price
under this agreement was $3.10 per MMcf. The final agreement, which will
terminate at the end of 2001, calls for Apache to supply up to 12 MMcf/d.
 
     Apache assumed its own U.S. crude oil marketing operations in 1992. Most of
Apache's crude oil production is sold through lease-level marketing to refiners,
traders and transporters, generally under 30-day contracts that renew
automatically until canceled.
 
     Oil produced from Canadian properties is sold to crude oil purchasers or
refiners at market prices which depend on world-wide crude prices adjusted for
transportation and crude quality. Natural gas produced from Canadian properties
is sold to major aggregators of natural gas, gas marketers and direct users
under long and short-term contracts. The oil and gas contracts provide for sales
at specified prices, or at prices which are subject to change due to market
conditions.
 
     The Company diversifies the markets for its Canadian gas production by
selling directly or indirectly to customers through aggregators and brokers in
the United States and Canada. Apache transports natural gas via the Company's
firm transportation contracts to California (12 MMcf/d) and to the Province of
Ontario, Canada (four MMcf/d) through end-users' firm transportation contracts.
Pursuant to an agreement entered into in 1994, the Company is also selling five
MMcf/d of natural gas to the Hermiston Cogeneration Project,
 
                                        5

located in the Pacific Northwest of the United States. In 1996, the Company
entered into an agreement with Westcoast Gas Services, Inc. for the sale of
5,000 MMBtu/d for delivery in the United States for a 10 year term. Sales under
the contract are contingent on regulatory approval of the required pipeline
expansion, and are expected to begin in 1998.
 
     In Australia, the Company has two contracts to deliver 32 Bcf of gas from
the East Spar field for industrial uses, including mining operations, a power
station and a nickel refinery. The contracts provide for an average daily rate
of 15 MMcf/d net to the Company. To provide deliveries under the contracts while
the East Spar development is under construction, the Harriet and East Spar joint
ventures, in both of which a subsidiary of the Company is a participant, entered
into a gas sales agreement under which the Harriet Joint Venture is supplying 42
MMcf of gas per day to East Spar's industrial customers. Apache operates the
Harriet Joint Venture and acts as contractor for the East Spar Joint Venture,
holding a 22.5 percent interest in Harriet and a 20 percent interest in East
Spar.
 
     In 1995, the Harriet Joint Venture entered into a take-or-pay contract to
supply natural gas under which AEL has committed 14 Bcf of reserves for delivery
over a 10-year period. Approximately 20 Bcf of AEL's proved gas reserves are
dedicated to the Gas Corporation of Western Australia, a corporation owned by
the government of Western Australia doing business as AlintaGas, under a
long-term contract which will expire in 2001. The agreement contains take-or-pay
provisions that require AlintaGas to purchase a minimum of 35 MMcf/d
(approximately eight MMcf/d net to AEL) through the remainder of the contract
term. Payments received under this contract are in Australian dollars.
 
     AEL marketed all oil and natural gas liquids produced from its interests in
the Harriet field during 1996 through a contract with Marubeni International
Petroleum (Singapore) Pte Limited (Marubeni). Pricing under the contract in 1996
represented a fixed premium to the quoted market prices of Tapis crude oil, with
payment made in U.S. dollars. In 1996, production sold under this contract
realized an average price of $22.33 per barrel (exclusive of the impact of
hedging activities). At the beginning of January 1997, the Marubeni contract was
terminated and replaced by a similar contract with Glencore International AG,
which includes East Spar liquids production.
 
     In Egypt, oil from the Qarun Block is delivered by pipeline to tanks owned
by the Company and its partners in the Qarun Concession at the Dashour pumping
station northeast of the Qarun Block or by truck to the Tebbin refinery south of
Alexandria, Egypt. At the discretion of the operator of the pipelines, oil from
the Qarun Block is put into the two 42-inch diameter SUMED pipelines, which
transport significant quantities of Egyptian and other crude oil from the Gulf
of Suez to Sidi Kherir, west of Alexandria, Egypt, on the Mediterranean Coast.
All Qarun and Khalda crude oil is currently sold to EGPC. In 1996, the Company
and its partners in the Khalda Block entered into a take or pay contract with
EGPC, which obligates EGPC to pay for 75 percent of 200 MMcf/d of future
production of gas from the Khalda Block. Sales of gas under the contract are
expected to begin in 1999 upon completion of the gas pipeline from the Khalda
Block.
 
OIL AND NATURAL GAS PRICES
 
     Natural gas prices remained volatile during 1996 with New York Mercantile
Exchange (NYMEX) spot-market prices at the Henry Hub ranging from $1.89 per
MMbtu in October to $3.61 per MMbtu in December. Fluctuations are largely due to
natural gas supply and demand perceptions. Apache's average realized gas price
of $2.02 per Mcf for 1996 increased 29 percent from the prior-year average of
$1.57 per Mcf. Apache's 1995 average realized natural gas price was 12 percent
lower than the 1994 average price of $1.78 per Mcf.
 
     Due to minimum price contracts which escalate at an average of 80 percent
of the Australian consumer price index, AEL's natural gas production in Western
Australia is not subject to the same degree of price volatility as Apache's U.S.
and Canadian gas production; however, natural gas sales under such Australian
minimum price contracts represent less than two percent of the Company's total
natural gas sales at the end of 1996. Total Australian gas sales in 1996,
including long-term contracts and spot sales averaged $1.96 per Mcf, a five
percent increase over the 1995 average of $1.86 per Mcf.
 
                                        6
<PAGE>   9
 
     In Egypt, all oil production from the Khalda and Qarun Blocks is currently
sold to EGPC on a spot basis at a "Western Desert" price which is applied to
virtually all production from the Western Desert and is announced from time to
time by EGPC. On December 31, 1996, that price was $23.74 per barrel.
Discussions with EGPC regarding the possibility of exporting Qarun oil
production are continuing. Once gas sales from the Khalda Block commence, the
gas is expected to be sold for a price which on a Btu basis is equivalent to 85
percent of the price of Suez Blend crude oil, FOB Mediterranean. Based on this
pricing formula, the price of Khalda gas per Mcf (at 1000 Btu per Mcf) would
have been roughly $3.80 at the end of 1996.
 
     Oil prices remained vulnerable to unpredictable political and economic
forces during 1996, but did not experience the wide fluctuations seen in natural
gas prices during the year. Apache believes that oil prices will continue to
fluctuate in response to changes in the policies of the Organization of
Petroleum Exporting Countries (OPEC), events in the Middle East and other
factors associated with the world political environment. As a result of the many
uncertainties associated with levels of production maintained by OPEC and other
oil producing countries, the availabilities of world-wide energy supplies and
the competitive relationships and consumer perceptions of various energy
sources, the Company is unable to predict what changes will occur in crude oil
and natural gas prices.
 
     Apache's worldwide crude oil price averaged $20.84 per barrel in 1996, up
22 percent from the average price of $17.09 per barrel in 1995, and 33 percent
higher than the average price of $15.65 per barrel in 1994. The Company's
average crude oil price for its Australian production, including production sold
under the Marubeni contract, was $22.33 per barrel in 1996, 20 percent higher
than the average price in 1995.
 
     Terms of the acquisition of MW from Amoco Production Company (Amoco)
included an oil and gas price sharing provision under which certain price
sharing payments may be payable to Amoco. Under this provision, to the extent
that oil prices exceed specified reference prices that rise to $33.12 per barrel
over the eight-year period ending June 30, 1999, and to the extent that gas
prices exceeded specified reference prices that rose to $2.68 per Mcf over the
five-year period ended June 30, 1996, Apache will share the excess price
realization with Amoco on a portion of the MW production. Apache was not
required to make any price sharing payments to Amoco in 1996.
 
     From time to time, Apache buys or sells contracts to hedge a limited
portion of its future oil and gas production against exposure to spot market
price changes. See Note 9 to the Company's consolidated financial statements
under Item 8 below.
 
     The Company's business has been and will continue to be affected by future
worldwide changes in oil and gas prices and the relationship between the prices
of oil and gas. No assurance can be given as to the trend in, or level of,
future oil and gas prices.
 
RESERVE VALUE CEILING TEST
 
     Under the full cost accounting rules of the Securities and Exchange
Commission (SEC), the Company reviews the carrying value of its oil and gas
properties each quarter on a country-by-country basis. Under full cost
accounting rules, capitalized costs of oil and gas properties may not exceed the
present value of estimated future net revenues from proved reserves, discounted
at 10 percent, plus the lower of cost or fair market value of unproved
properties, as adjusted for related tax effects and deferred income taxes.
Application of these rules generally requires pricing future production at the
unescalated oil and gas prices in effect at the end of each fiscal quarter and
requires a write-down if the "ceiling" is exceeded, even if prices declined for
only a short period of time. If a write-down is required, the one-time charge to
earnings would not impact cash flow from operating activities. The Company had
no write-downs due to ceiling test limitations during 1996.
 
GOVERNMENT REGULATION OF THE OIL AND GAS INDUSTRY
 
     The Company's exploration, production and marketing operations are
regulated extensively at the federal, state and local levels, as well as by
other countries in which the Company does business. Oil and gas exploration,
development and production activities are subject to various laws and
regulations governing a wide variety of matters. For example,
hydrocarbon-producing states have statutes or regulations addressing
 
                                        7
<PAGE>   10
 
conservation practices and the protection of correlative rights, and such
regulations may affect Apache's operations and limit the quantity of
hydrocarbons Apache may produce and sell. Other regulated matters include
marketing, pricing, transportation, and valuation of royalty payments.
 
     At the U.S. federal level, the Federal Energy Regulatory Commission (FERC)
regulates interstate transportation of natural gas under the Natural Gas Act.
Effective January 1, 1993, the Natural Gas Wellhead Decontrol Act deregulated
natural gas prices for all "first sales" of natural gas, which includes all
sales by Apache of its own production. As a result, all sales of the Company's
natural gas produced in the U.S. may be sold at market prices, unless otherwise
committed by contract.
 
     Apache's gas sales are affected by regulation of intrastate and interstate
gas transportation. In an attempt to promote competition, the FERC has issued a
series of orders which have altered significantly the marketing and
transportation of natural gas. The effect of these orders has been to enable the
Company to market its natural gas production to purchasers other than the
interstate pipelines located in the vicinity of its producing properties. The
Company believes that these changes have generally improved the Company's access
to transportation. To date, Apache has not experienced any material adverse
effect on its gas marketing activities as a result of these FERC orders;
however, the Company cannot predict what new regulations may be adopted by the
FERC and other regulatory authorities, or what effect subsequent regulations may
have on its future gas marketing activities.
 
ENVIRONMENTAL MATTERS
 
     Apache, as an owner or lessee and operator of oil and gas properties, is
subject to various federal, provincial, state, local and foreign country laws
and regulations relating to discharge of materials into, and protection of, the
environment. These laws and regulations may, among other things, impose
liability on the lessee under an oil and gas lease for the cost of pollution
clean-up resulting from operations, subject the lessee to liability for
pollution damages, and require suspension or cessation of operations in affected
areas.
 
     Apache maintains insurance coverage which it believes is customary in the
industry, although it is not fully insured against all environmental risks. The
Company is not aware of any environmental claims existing as of December 31,
1996, which would have a material impact upon the Company's financial position
or results of operations.
 
     Apache has made and will continue to make expenditures in its efforts to
comply with these requirements, which it believes are necessary business costs
in the oil and gas industry. The Company has established policies for continuing
compliance with environmental laws and regulations, including regulations
applicable to its operations in Canada, Australia and other countries. Apache
also has established operational procedures and training programs designed to
minimize the environmental impact of its field facilities. The costs incurred by
these policies and procedures are inextricably connected to normal operating
expenses such that the Company is unable to separate the expenses related to
environmental matters; however, the Company does not believe any such additional
expenses are material to its financial position or results of operations.
 
     Although environmental requirements have a substantial impact upon the
energy industry, generally these requirements do not appear to affect Apache any
differently, or to any greater or lesser extent, than other companies in the
industry. Apache does not believe that compliance with federal, state, local or
foreign country provisions regulating the discharge of materials into the
environment, or otherwise relating to the protection of the environment, will
have a material adverse effect upon the capital expenditures, earnings or
competitive position of the Company or its subsidiaries; however, there is no
assurance that changes in or additions to laws or regulations regarding the
protection of the environment will not have such an impact.
 
COMPETITION
 
     The oil and gas industry is highly competitive. Because oil and gas are
fungible commodities, the principal form of competition with respect to product
sales is price competition. Apache strives to maintain the lowest finding and
production costs possible to maximize profits.
 
                                        8
<PAGE>   11
 
     As an independent oil and gas company, Apache frequently competes for
reserve acquisitions, exploration leases, licenses, concessions and marketing
agreements against companies with substantially larger financial and other
resources than Apache possesses. Moreover, many competitors have established
strategic long-term positions and maintain strong governmental relationships in
countries in which the Company may seek new entry. Apache expects this high
degree of competition to continue.
 
INSURANCE
 
     Exploration for and production of oil and natural gas can be hazardous,
involving unforeseen occurrences such as blowouts, cratering, fires and loss of
well control, which can result in damage to or destruction of wells or
production facilities, injury to persons, loss of life or damage to property or
the environment. The Company maintains insurance against certain losses or
liabilities arising from its operations in accordance with customary industry
practices and in amounts that management believes to be prudent; however,
insurance is not available to the Company against all operational risks.
 
EMPLOYEES
 
     On December 31, 1996, Apache had 1,256 employees.
 
OFFICES
 
     Apache's principal executive offices are located at One Post Oak Central,
2000 Post Oak Boulevard, Suite 100, Houston, Texas 77056-4400. At year-end 1996,
the Company maintained regional exploration and production offices in Tulsa,
Oklahoma; Houston, Texas; Calgary, Alberta; Cairo, Egypt; and Perth, Western
Australia.

ESTIMATED RESERVES AND RESERVE VALUE INFORMATION
 
     The following information relating to estimated reserve quantities, reserve
values and discounted future net revenues is derived from, and qualified in its
entirety by reference to, the more complete reserve and revenue information and
assumptions included in the Company's supplemental oil and gas disclosures under
Item 8 below. The Company's estimates of proved reserve quantities of its U.S.,
Canadian and certain international properties have been subject to review by
Ryder Scott Company Petroleum Engineers, while the proved reserve quantities of
the Company's Egyptian properties are reviewed by Netherland, Sewell &
Associates, Inc. There are numerous uncertainties inherent in estimating
quantities of proved reserves and projecting future rates of production and
timing of development expenditures. The following reserve

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS
 
OVERVIEW
 
     Apache's results of operations and financial position during 1996 were
significantly impacted by the following factors:
 
     Commodity Prices -- Higher oil and natural gas prices contributed to record
earnings and cash flow in 1996. Apache's average realized natural gas price for
1996 was up 29 percent over 1995, favorably impacting revenues by $93.4 million.
The Company's average realized oil price for 1996 increased 22 percent from
1995, contributing $73.0 million to the increase in revenues.
 
     Phoenix Acquisition -- On May 20, 1996, Apache acquired Phoenix, through a
merger which resulted in Phoenix becoming a wholly owned subsidiary of Apache.
The assets acquired in the Phoenix acquisition contributed 6,260 b/d of oil
production during 1996.
 
     Debt Refinancing -- During 1996, Apache offered three issues of senior
unsecured notes and debentures with principal amounts of $100 million in
February, $180 million in April and $150 million in November. In October 1996,
Apache replaced its existing $1 billion revolving bank credit facility with a
global credit arrangement (global credit facility) that provides Apache with
greater borrowing availability, increased tax efficiency and a lower cost of
bank debt. Additionally, in September and October 1996, Apache received rating
upgrades on its long-term debt from Moody's Investors Service and Duff and
Phelps.
 
RESULTS OF OPERATIONS
 
NET INCOME AND REVENUE
 
     Apache reported 1996 net income of $121.4 million, up from $20.2 million in
1995. Net income per common share rose to $1.42, a five-fold increase from $.28
a year earlier, despite additional shares outstanding. Higher oil and gas prices
and increased oil production drove the increase in earnings but were partially
offset by lower natural gas production and higher lease operating expenses.
Additionally, 1995 results were negatively impacted by a one-time after-tax
charge of $8.7 million, or $.12 per share, associated with merger costs.
 
     Revenues increased 30 percent in 1996 to $977.2 million as compared to
$750.7 million for the same period in 1995. Crude oil and natural gas production
revenue increased 28 percent compared to 1995 with crude oil contributing 49
percent and natural gas contributing 50 percent of total oil and gas production
revenue.

     Natural gas sales for 1996 of $415.7 million increased $85.0 million, or 26
percent, when compared to 1995, as the impact of favorable natural gas prices
more than offset production declines. A $.53 per Mcf increase in realized price
attributable to United States natural gas production, which comprised 84 percent
of the Company's worldwide gas production, contributed $92.0 million to the
increase in sales. Offsetting this increase was a $16.2 million reduction in
sales due to a decline in United States production compared to the same period
in 1995, due primarily to the natural decline of older properties in the
Company's Offshore and Gulf Coast regions and the sale of producing properties
in late 1995. Canadian and Australian gas sales contributed $5.3 million and
$3.5 million, respectively, to the increase in revenue as a result of higher
realized prices and increased production in both countries. The Company's net
hedging activity, including fixed-price physical contracts and financial
contracts, reduced realized prices by $.09 per Mcf during the year ended
December 31, 1996, compared to a $.07 per Mcf gain during 1995. The 1995 gain
was driven substantially by higher margins on the Company's premium-price gas
contracts, given low spot market prices during 1995.

<PAGE>   20
 
     For the year ended December 31, 1996, oil sales increased 30 percent to
$405.7 million due primarily to the assets acquired in the Phoenix Merger.
Egyptian oil sales contributed $64.6 million, or 70 percent, of the increase in
oil sales compared to 1995, and comprised 16 percent of total oil production.
United States oil sales were favorably impacted by a 22 percent increase in
realized prices, which contributed $54.5 million to the increase in revenue
compared to 1995. Partially offsetting the impact due to higher realized
domestic prices was a 10 percent decline in domestic oil production resulting
from property sales in late 1995, which reduced revenues by $27.1 million.
Canadian oil sales contributed $2.7 million of the increase in oil sales
compared to 1995 due primarily to higher realized prices. Australian oil sales
were impacted by a 26 percent decline in production compared to 1995, partially
offset by higher realized prices, resulting in a net decrease in revenue of $2.2
million.
 
     For 1996, natural gas liquid revenues increased 27 percent to $11.7
million. Compared to the prior year, realized prices increased 36 percent,
contributing $3.1 million to the increase in revenues, while production declined
seven percent, decreasing revenues $.6 million.
 
OTHER REVENUES AND OPERATING EXPENSES
 
     During 1996, Apache's gas gathering, processing and marketing revenues
increased 47 percent to $142.9 million driven primarily by increased product
prices. Although revenues have increased with respect to these activities, lower
margins were realized for the year ended December 31, 1996 compared to the same
period in 1995.
 
     For 1996, other revenue of $1.4 million included a gain on the sale of
stock held for investment of $.8 million and Canadian royalty credits of $1.2
million. Offsetting these revenues was the impact of $.9 million of currency
transaction loss related to Canadian exchange rate fluctuations. Prior year
other revenue was $1 million lower than 1996 and included $4.3 million in
proceeds received from settlements, $2.2 million in gains from the sales of
non-oil and gas assets, $1.1 million of Canadian royalty credits and $2.1
million of other income, offset by $9.3 million in losses from the decoupling of
NYMEX and wellhead prices.
 
     The Company's depreciation, depletion and amortization (DD&A) expense for
1996 totaled $315.1 million up from $297.5 million in 1995. On an equivalent
barrel basis, full cost DD&A expense increased $.12 per boe, from $5.32 per boe
in 1995 to $5.44 per boe in 1996.
 
     Operating costs totaled $225.5 million in 1996, an increase of $13.8
million, or seven percent, from 1995. Lease operating expense (LOE), excluding
severance taxes, totaled $186.4 million, a 2.9 percent increase from 1995. On an
equivalent barrel basis, LOE for the year ended December 31, 1996, averaged
$3.43 per boe, a three percent increase from $3.34 per boe in 1995. The increase
was driven by a flat cost structure with declining production in the Gulf Coast
region and the impact of the Phoenix acquisition, partially offset by decreasing
LOE per boe in the Midcontinent region resulting from incremental production
added through the drillbit.
 
     Administrative, selling and other costs in 1996 decreased $.6 million, or
two percent. The decline is a result of the Company's continuing efforts to
control costs and its ability to integrate the assets and operations acquired in
1995 and 1996 with a minimal increase in administrative staff. On an equivalent
barrel basis, general and administrative expense declined two percent from 1995
to $.66 per boe in 1996.
 
     Net financing costs for 1996 decreased $9.0 million, or 13 percent, from
the prior year due to higher amounts of capitalized interest, partially offset
by higher gross interest costs. Capitalized interest, which is based on the
carrying value of unproved properties, increased $11.7 million for 1996 due to
the acquisitions made in 1995 and 1996 and the resulting increase in the
unproved property base. Gross interest incurred increased $1.8 million for 1996
as compared to 1995. Average corporate debt increased $78.8 million compared to
1995, increasing interest expense by $6.1 million. Offsetting this increase was
a decline of .36 percent in Apache's weighted average interest rate, resulting
in a decrease in interest expense of $4.3 million.

HEDGING ACTIVITY
 
     The Company periodically enters into hedging activities with respect to a
portion of its projected oil and natural gas production through a variety of
financial and physical arrangements intended to support oil and natural gas
prices at targeted levels and to manage its exposure to oil and gas price
fluctuations. Apache uses futures contracts, swaps, options and fixed-price
physical contracts to hedge its commodity prices. Realized gains or losses from
the Company's price risk management activities are recognized in oil and gas
production revenues when the associated production occurs.
 
     In 1996, Apache recognized net losses from hedging activities, including
both financial and fixed price physical gas contracts, which decreased oil and
gas production revenues by approximately $5.1 million and $18.7 million,
respectively. These losses decreased the Company's average realized oil and
natural gas prices in 1996 by $.26 per barrel and $.09 per Mcf, respectively.
 
PRIOR-YEAR COMPARATIVE INFORMATION
 
     Apache reported net income for 1995 of $20.2 million, or $.28 per share,
compared with $45.6 million, or $.65 per share in 1994. The decline was due to
lower natural gas realizations and non-recurring charges. Absent one-time
after-tax charges for merger costs of $8.7 million and losses recognized in
connection with the decoupling of NYMEX and wellhead prices of $5.9 million
($9.3 million before tax), 1995 earnings would have totaled $.48 per share.
 
     Revenues increased 27 percent in 1995 to $750.7 million as compared to
$592.6 million in 1994. Crude oil and natural gas production revenue increased
21 percent compared to 1994, with crude oil contributing 48 percent and natural
gas contributing 51 percent of total oil and gas production revenues.
 
     Natural gas sales for 1995 of $330.7 million increased five percent from
1994 as production gains from acquisitions and drilling more than offset the
impact of a $.21 per Mcf decline in the Company's average realized gas price.
Acquisitions boosted Apache's 1995 gas production by 92 MMcf/d, while drilling
additions outpaced the impact of property divestitures and natural depletion.
Apache realized production gains in each of its three operating areas: the
United States, Canada and Australia. In addition to production gains from
drilling, the Australian sales benefited from new markets for its natural gas.
The Company's average realized natural gas price declined 12 percent from 1994,
decreasing sales by approximately $44 million.
 
     Reflecting an increase in both production and prices, oil sales increased
45 percent in 1995 to $313.2 million. Apache's oil production rose 12.4 Mb/d, or
33 percent, from 1994 as property divestitures and natural depletion partially
offset the 17 Mb/d of production added through acquisitions. The Company's
average realized oil price increased nine percent in 1995 to $17.09 per barrel.
 
     Revenues from the sale of natural gas liquids totaled $9.2 million in 1995,
up 13 percent from 1994 due to higher prices and a slight increase in volumes.
 
     During 1995, Apache's gas gathering, processing and marketing revenues more
than doubled from 1994 to $97.2 million. Revenues increased in 1995 with respect
to these activities due to increased volumes; however, margins were lower due to
the sale of the Company's interest in the Little Knife gas plant as part of
Apache's divestiture of Rocky Mountain properties in September 1995.
 
     Other revenues in 1995 of $.4 million reflects $4.3 million of settlement
income, $2.2 million in gains from the sale of non-oil and gas assets, $1.1
million of Canadian royalty credits and $2.1 million of other income, offset by
a $9.3 million loss from the decoupling of NYMEX futures and wellhead prices.
 
     The Company's DD&A expense for 1995 totaled $297.5 million compared to
$257.8 million in 1994. On an equivalent barrel basis, full cost DD&A declined
six percent to $5.32 per boe, due to the favorable impact of reserve additions
and revisions.
 
     Operating costs totaled $211.7 million in 1995, an increase of $62.3
million or 42 percent from 1994. LOE, excluding severance taxes, totaled $181.1
million, an increase of $55.8 million from 1994. On an equivalent unit of
production basis, LOE for the year ended December 31, 1995, averaged $3.34 per
boe, a
 
                                       19
<PAGE>   22
 
17 percent increase from $2.85 per boe in 1994. The increase in unit cost
reflects the high percentage of oil properties comprising the Texaco
acquisition, as oil properties typically have a higher per-unit cost than gas
properties.
 
     Administrative, selling and other costs in 1995 decreased $2.2 million, or
six percent, due primarily to the elimination of duplicate administrative
functions following the merger of DEKALB into Apache. On an equivalent unit of
production basis, general and administrative expenses declined 24 percent from
1994 to $.67 per boe.
 
     Net financing costs of $70.6 million were more than double the 1994 amount
due to increased debt levels from acquisitions and higher interest rates.
Apache's average interest rate increased from 6.3 percent in 1994 to 7.4 percent
in 1995 due to higher market rates and Apache's higher debt to total
capitalization rate following the acquisition of properties from Texaco.
 
CASH FLOW, LIQUIDITY AND CAPITAL RESOURCES
 
CAPITAL COMMITMENTS
 
     Apache's primary needs for cash are for exploration, development and
acquisition of oil and gas properties, repayment of principal and interest on
outstanding debt, payment of dividends, and capital obligations for affiliated
ventures. The Company generally funds its exploration and development activities
through internally generated cash flows. Apache budgets its capital expenditures
based upon projected cash flows and routinely adjusts its capital expenditures
in response to changes in oil and natural gas prices and corresponding changes
in cash flow. The Company is not in a position to predict future product prices.
 
     Capital Expenditures -- A summary of oil and gas capital expenditures over
the last three years is presented below:

</TABLE>
 
     Expenditures for exploration and development totaled $493.7 million in 1996
compared to $312.2 million in 1995. Apache's drilling program in 1996 added 98
MMboe of reserves (including revisions), replacing 179 percent of production. In
the United States, Apache completed 229 gross wells as producers out of 293
gross wells drilled during the year, compared with 138 gross producers out of
174 gross wells drilled in 1995. In Canada, Apache completed 50 gross wells as
producers out of 77 gross wells drilled during the year, compared with 30 gross
producers out of 48 gross wells drilled in 1995.
 
     Internationally, the Company completed 24 gross producers of 36 gross wells
drilled in 1996, compared to 12 gross producers out of 26 gross wells in 1995.
The international wells drilled in 1996 included 19 successful wells in Egypt
and five successful wells in Australia.
 
     United States and Canadian expenditures for exploration and development in
1997 operations, are expected to exceed the 1996 expenditures by approximately
$60 million. The Company expects its other international exploration and
development expenditures in 1997, exclusive of facilities, to total
approximately $220 million.
 
     Acquisition costs of oil and gas properties, including the value assigned
to shares issued and issuable and liabilities assumed in the Phoenix merger,
totaled $446.2 million in 1996 compared to $820.9 million in 1995.
 
                                       20
<PAGE>   23
 
Property acquired in the Phoenix merger totaled $386.2 million of which $331.2
million related to oil and gas properties and $55.0 million to facilities.
Apache also acquired $115.0 million of other oil and gas properties during 1996,
primarily representing tactical acquisitions of properties in the Company's
existing focus areas, including the purchase of certain oil and gas properties
from Hall-Houston for $46 million in cash. Funds for the acquisitions were
obtained principally from borrowings under the Company's revolving bank credit
facilities.
 
     Cash expenditures for acquisitions of oil and gas properties during 1995
totaled $820.9 million as the Company added 156 MMboe of oil and gas reserves
through purchases. The most significant of the 59 transactions Apache completed
during 1995 were the Company's acquisitions of properties from Texaco and
Aquila.
 
     On March 1, 1995, Apache purchased certain United States oil and gas
properties from Texaco for approximately $567 million in cash, subject to
adjustment. Funds for the Texaco transaction were obtained from several sources,
including increased borrowing capacity under the Company's revolving bank credit
facility and proceeds of Apache's $172.5 million 6 percent Convertible
Subordinated Debentures due 2002 (6 percent debentures), which were issued on
January 4, 1995.
 
     In September 1995, Apache acquired the Aquila Assets for approximately $210
million. The oil and gas properties included approximately 107,000 developed and
49,000 undeveloped net acres located primarily in Apache's Anadarko Basin and
Gulf of Mexico core areas. Also included in the transaction was the purchase of
a five-year, four-month premium-price gas contract and interests in four gas
processing plants.
 
     Cash expenditures for 1994 acquisitions, excluding AERC, totaled $180.7
million. The most significant acquisition that Apache closed during 1994 was the
purchase of substantially all of the United States oil and gas properties of
Crystal Oil Company for $95.8 million. Apache also acquired approximately $84.9
million of other oil and gas properties through a number of separate
transactions during 1994. Funds for the 1994 acquisitions were obtained
principally from borrowings under the Company's revolving bank credit facility.
 
     Debt and Interest Commitments -- At December 31, 1996, Apache had
outstanding debt of $376.5 million under its global credit facility and an
aggregate of $861.2 million of other debt, comprised principally of notes and
debentures maturing in the years 1997 through 2096. Debt outstanding at December
31, 1996 of $1.2 billion was up 15 percent over the $1.1 billion outstanding at
December 31, 1995. The increase reflects the Phoenix Merger and other 1996
property acquisitions. Although debt increased, the Company's debt-to-
capitalization ratio decreased from 49.6 percent at December 31, 1995 to 44.9
percent at December 31, 1996.
 
     During 1996, the Company significantly extended maturity dates of its
long-term debt with long-term offerings and reduced outstanding balances of its
shorter-term, variable-rate debt. In February, Apache issued $100 million
principal amount of 7.7 percent notes due 2026. In April, $180 million principal
amount of 7.95 percent notes due 2026 was issued and, in November, Apache
completed the issuance of 7.625 percent debentures due 2096 for a principal
amount of $150 million. Interest payments on the Company's outstanding debt
obligations during 1997 are projected (using weighted average balances for
floating rate obligations) to be approximately $99.5 million, while scheduled
principal payments for 1997 total $77 million. However, the $75 million
principal amount of 3.93 percent convertible notes due in November 1997 is not
reflected as current maturities in the Company's consolidated balance sheet, as
such notes are expected to be refinanced with long-term debt if not converted
into Apache common stock.
 
     Dividend Payments -- Dividends paid during 1996 totaled $23.4 million, up
24 percent from 1995, primarily due to the issuance of 12.2 million shares of
Apache common stock in connection with the May 1996 acquisition of Phoenix. The
Company has paid cash dividends on its common stock for 120 consecutive quarters
through December 31, 1996, and expects to continue payment of dividends at
current levels, although future dividend payments will depend on the Company's
level of earnings, financial requirements and other relevant factors.

CAPITAL RESOURCES AND LIQUIDITY
 
     The Company's primary capital resources are net cash provided by operating
activities, proceeds from financing activities and proceeds from sales of
non-strategic assets.
 
     Net Cash Provided by Operating Activities -- Apache's net cash provided by
operating activities during 1996 totaled $490.5 million, an increase of 48
percent from the $332.1 million provided in 1995. This increase was due
primarily to higher product prices during 1996. Net cash provided by operating
activities in 1995 was down $25.6 million from 1994 primarily due to the
prior-year amounts including a $67.4 million advance of future gas deliveries.
 
     Long-Term Borrowings -- During February 1996, Apache completed the issuance
of $100 million principal amount, $99.6 million after discount, of senior
unsecured 7.7 percent notes due March 15, 2026. In April 1996, the Company
issued $180 million principal amount, $178.5 million net of discount, of senior
unsecured 7.95 percent notes due on April 15, 2026. In November 1996, Apache
completed the issuance of $150 million, $149.2 million after discount, of senior
unsecured 7.625 percent debentures due November 1, 2096. The proceeds from these
issuances were used to repay a portion of the Company's revolving bank credit
facility and for general corporate purposes.
 
     The offerings of the two 30-year notes and the 100-year debentures were
placed during periods when 30-year interest rates on Treasury bonds were near
historic 20-year lows. Further, the 100-year debentures were issued following
recent upgrades of the Company's long-term debt ratings which resulted in a
significant narrowing in the spread over the Treasury bond yields. In addition
to the benefits of securing longer-term financing at favorable interest rates
and reducing Apache's exposure to future adverse interest rate fluctuations, the
issuance of the 30-year notes improved the Company's liquidity as the borrowing
base under the Company's global credit facility was reduced by an amount less
than the net proceeds received from issuing the notes.
 
     On October 31, 1996, Apache replaced its existing $1 billion revolving bank
credit facility with a global credit facility that provides Apache with greater
borrowing availability, increased tax efficiency and a lower cost of bank debt.
Consisting of three separate bank facilities tied together by an intercreditor
agreement, the new global credit facility adds Apache's oil and gas reserve
values in Australia and Canada to those in the United States in determining the
Company's borrowing capacity. The facilities consist of $125 million of credit
commitments each in Australia and Canada, and a $750 million credit commitment
in the United States. In connection with securing the global credit facility,
the Company repaid certain of its subsidiary debt, including DEKALB's 10 percent
notes, the Apache Canada Ltd. facility (the Bank of Montreal facility) and the
AEL acceptance facility, all of which had higher interest rates than those under
the global credit facility. As of December 31, 1996, Apache's borrowing base
under the global credit facility was $947 million, of which defined borrowing
base debt was $733 million, leaving $214 million available for additional
borrowings.
 
     During September 1996, Moody's Investor's Service upgraded the Company's
senior long-term debt rating from Baa3 to Baa1. Historically, such a two-notch
rating improvement for an existing investment grade company is uncommon. In
addition, Apache's subordinated debt rating was raised three levels, to Baa2
from Ba2. According to Moody's, the upgrade was the result of several recent
developments, including the Company's lower debt-to-equity ratio, higher
earnings and cash flow, lower interest expense, successful expansion in Egypt
and Western Australia, and a shift in the Company's strategy toward growing
reserves and production primarily through drilling. Also in September 1996,
Standard & Poor's revised its outlook to "positive" from "stable" on Apache's
long-term debt. Standard & Poor's subsequently upgraded the Company's senior
long-term debt from BBB to BBB+ and subordinated debt from BBB- to BBB in
January 1997.
 
     In October 1996, Duff & Phelps Credit Rating Co. upgraded the Company's
senior long-term debt from BBB+ to A-, its 6 percent subordinated debentures
from BBB to BBB+, and its commercial paper from D-2 to D-1-(D-One-Minus).
 
                                       22
<PAGE>   25
 
     In January 1997, the Company established a $300 million commercial paper
program. The program allows Apache to borrow funds for up to 270 days at
attractive interest rates. The commercial paper program is supported by
availability under the $750 million United States portion of the global credit
facility.
 
     Stock Transactions -- On May 20, 1996, Apache acquired Phoenix. Pursuant to
the Merger Agreement, each share of Phoenix common stock then outstanding, and
outstanding Phoenix stock options (which were assumed by Apache) were converted
into the right to receive (a) .75 shares of Apache common stock with any
fractional shares paid in cash, without interest, and (b) $4.00 in cash. As a
result, 12.2 million shares of Apache common stock, valued at $26.00 per share,
were issued in exchange for outstanding Phoenix stock with an additional .8
million shares issuable under options assumed.
 
     On September 27, 1995, Apache closed an equity offering of 7.45 million
shares of Apache common stock. Net proceeds of approximately $195.5 million were
used to repay existing indebtedness under the Company's revolving bank credit
facility, to finance the Aquila transaction and for general corporate purposes.
 
     Asset Sales -- During 1996, Apache received $30.1 million from the sale of
non-strategic oil and gas properties in a number of separate transactions. In
early 1995, Apache announced plans to accelerate the disposition of lower-margin
and non-strategic properties, including the sale of a substantial portion of its
Rocky Mountain properties. During 1995, Apache received $271.9 million from the
sale of such properties, utilizing the proceeds to reduce bank debt. Apache
received $19.5 million from the sale of non-strategic oil and gas properties
during 1994.
 
     Liquidity -- The Company had $13.2 million in cash and cash equivalents on
hand at December 31, 1996, down slightly from the $13.6 million at December 31,
1995. Apache's ratio of current assets to current liabilities decreased slightly
from .90:1 at December 31, 1995, to .87:1 at December 31, 1996.
 
     Management believes that cash on hand, net cash generated from operations
and unused committed borrowing capacity under its global credit facility will be
adequate to satisfy the Company's financial obligations to meet future liquidity
needs for at least the next two fiscal years.
 
FUTURE TRENDS
 
     Apache's growth strategy is to increase oil and gas reserves, production,
and cash flow through a combination of exploratory drilling, development of its
inventory of existing projects and, principally in North America, tactical
acquisitions meeting defined financial parameters. The Company's drilling
program emphasizes reserve additions through exploratory drilling primarily on
its international interests, and moderate-risk drilling primarily on its North
American interests. The Company also emphasizes reducing operating costs per
unit produced and selling marginal and non-strategic properties in order to
increase its profit margins.
 
     Apache's international investments and exploration activities are an
important component of its long-term growth strategy. Although international
exploration is recognized as higher-risk than most of Apache's U.S. and Canadian
activities, it offers potential for greater rewards and significant reserve
additions. Apache directed its international efforts in 1996 toward development
of certain discoveries offshore Western Australia and in Egypt, and toward
further exploration efforts on its concessions in Egypt, offshore The People's
Republic of China, in Indonesia and offshore the Ivory Coast of western Africa.
Apache believes that reserve additions in these international areas may be made
through higher-risk exploration and through improved production practices and
recovery techniques.
 
     For Apache, property acquisition is only one phase in a continuing cycle of
business growth. Apache's aim is to follow each acquisition with a cycle of
reserve enhancement, property consolidation and cash flow acceleration,
facilitating asset growth and debt reduction. This approach requires a
well-planned and carefully executed property development program and, where
appropriate, a selective program of property dispositions. It motivates Apache
to target acquisitions that have ascertainable additional reserve potential and
to apply an active drilling, workover and recompletion program to realize the
potential of the acquired undeveloped and partially developed properties. Apache
prefers to operate its properties so that it can best influence their
development; as a result, the Company operates properties accounting for over 75
percent of its production.
 
                                       23
<PAGE>   26
 
     In 1997, Apache expects North American exploration and development outlays
to increase from 1996 levels as the Company focuses on increasing reserves,
production and cash flow through exploratory drilling and development of its
existing inventory. Internationally, the Company projects capital expenditures
to nearly double from 1996 as Apache continues to exploit its concessions in
Egypt, Western Australia, China and Indonesia. Proposed exploration and
development expenditures in 1997 will be reviewed at least every quarter in
light of fluctuating product prices and Apache's objective to fund operations
through internally generated cash flow.
 
     On October 31, 1996, subject to shareholder approval, Apache's Board of
Directors adopted the 1996 Share Price Appreciation Plan for officers and
certain key employees. The plan provides for awards denominated in shares of
Apache common stock to become payable upon attainment of share price goals of
$50 and $60 per share, respectively, before January 1, 2000. Between 30 and 50
percent of the number of shares awarded will be paid in cash at the market value
of the stock on the date of payments, and the balance (up to a total of
2,000,000 shares in the aggregate) will be issued in Apache common stock.
Generally, any payments will be made in three installments over 36 months. When
and if payments are made, the Company will recognize compensation expense over
the 36 month vesting period equal to the value of the stock issued on the date
the share price goal is attained (i.e., $50 or $60, as appropriate) and the
actual amount of cash paid.

          The following reports on Form 8-K were filed by Apache during the
     fiscal quarter ended December 31, 1996:
 
          October 31, 1996 -- Item 5. Other Events -- Apache amended and
     restated its main revolving credit facility on October 31, 1996, to provide
     for a new global credit facility consisting of three principal agreements,
     with an aggregate credit commitment, subject to borrowing base
     availability, of $1 billion. The global credit facility adds Apache's oil
     and gas reserve values in Canada and Australia to those in the United
     States in determining Apache's global borrowing base. Also, on October 25,
     1996, Apache announced a purchase/sale program for odd-lot shareholders.
 
          October 31, 1996 -- Item 5. Other Events -- Offering to the public of
     $150 million principal amount of Apache's 7.625% Debentures due 2096,
     issuable under an indenture, dated February 15, 1996 and supplemented
     November 5, 1996, and registered pursuant to Apache's Registration
     Statement on Form S-3 (File No. 333-12669).

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
TO THE SHAREHOLDERS OF APACHE CORPORATION:
 
     We have audited the accompanying consolidated balance sheet of Apache
Corporation (a Delaware corporation) and Subsidiaries as of December 31, 1996
and 1995, and the related statements of consolidated income, shareholders'
equity, and cash flows for each of the three years in the period ended December
31, 1996. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits. We did not audit the financial statements of
DEKALB Energy Company, a company acquired during 1995 in a transaction accounted
for as a pooling of interests, for the year ended December 31, 1994, as
discussed in Note 2. Such financial statements are included in the consolidated
financial statements of Apache Corporation and Subsidiaries and reflect total
revenues of eight percent of the related consolidated total for the year ended
December 31, 1994, after restatement to reflect certain adjustments as set forth
in Note 2. The financial statements of DEKALB Energy Company, prior to those
adjustments, were audited by other auditors whose report has been furnished to
us and our opinion, insofar as it relates to 1994 amounts included for DEKALB
Energy Company, is based solely upon the report of the other auditors.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits, and the report of other auditors, provide a
reasonable basis for our opinion.
 
     In our opinion, based on our audits and the report of other auditors, the
consolidated financial statements referred to above present fairly, in all
material respects, the financial position of Apache Corporation and Subsidiaries
as of December 31, 1996 and 1995, and the results of their operations and their
cash flows for each of the three years in the period ended December 31, 1996, in
conformity with generally accepted accounting principles.

                                AUDITORS' REPORT
 
TO THE SHAREHOLDERS AND BOARD OF DIRECTORS OF DEKALB ENERGY COMPANY:
 
     We have audited the consolidated balance sheet of DEKALB Energy Company as
at December 31, 1994 and the consolidated statements of operations,
shareholders' equity and cash flows for the year ended December 31, 1994. These
consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform an audit to obtain
reasonable assurance whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
 
     In our opinion, these consolidated financial statements present fairly, in
all material respects, the consolidated financial position of DEKALB Energy
Company as at December 31, 1994 and the consolidated results of its operations
and its cash flows for the year ended December 31, 1994, in accordance with
United States generally accepted accounting principles.

                              REPORT OF MANAGEMENT
 
     The financial statements and related financial information of Apache
Corporation and Subsidiaries were prepared by and are the responsibility of
management. The statements have been prepared in conformity with generally
accepted accounting principles and include amounts that are based on
management's best estimates and judgments.
 
     Management maintains and places reliance on systems of internal control
designed to provide reasonable assurance, weighing the costs with the benefits
sought, that all transactions are properly recorded in the Company's books and
records, that policies and procedures are adhered to, and that assets are
safeguarded. The systems of internal controls are supported by written policies
and guidelines, internal audits and the selection and training of qualified
personnel.
 
     The financial statements of Apache Corporation and Subsidiaries, except for
DEKALB Energy Company prior to 1995, have been audited by Arthur Andersen LLP,
independent public accountants. The financial statements of DEKALB Energy
Company and its subsidiaries for 1994 were audited by Coopers & Lybrand. Their
audits included developing an overall understanding of each Company's accounting
systems, procedures and internal controls and conducting tests and other
auditing procedures sufficient to support their opinions on the fairness of the
respective consolidated financial statements.
 
     The Apache Corporation Board of Directors exercises its oversight
responsibility for the financial statements through its Audit Committee,
composed solely of directors who are not current or former employees of Apache.
The Audit Committee meets periodically with management, internal auditors and
the independent public accountants to ensure that they are successfully
completing designated responsibilities. The internal auditors and independent
public accountants have open access to the Audit Committee to discuss auditing
and financial reporting issues.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Nature of Operations -- Apache Corporation (Apache or the Company) is an
independent energy company that explores for, develops and produces natural gas,
crude oil and natural gas liquids. The Company's North American exploration and
production activities are divided into four U.S. operating regions (Offshore,
Midcontinent, Gulf Coast and Western), plus a Canadian region. Approximately 82
percent of the Company's proved reserves are located in North America.
Internationally, Apache has exploration and production interests offshore
Western Australia and in Egypt, and exploration interests offshore The People's
Republic of China, in Indonesia and offshore the Ivory Coast. Apache treats all
operations as one segment of business.
 
     The Company's future financial condition and results of operations will
depend upon prices received for its oil and natural gas production and the costs
of finding, acquiring, developing and producing reserves. A substantial portion
of the Company's production is sold under market-sensitive contracts. Prices for
oil and natural gas are subject to fluctuations in response to changes in
supply, market uncertainty and a variety of other factors beyond the Company's
control. These factors include worldwide political instability (especially in
the Middle East), the foreign supply of oil and natural gas, the price of
foreign imports, the level of consumer demand, and the price and availability of
alternative fuels. With natural gas accounting for 63 percent of Apache's 1996
production on an energy equivalent basis, the Company was affected more by
fluctuations in natural gas prices than in oil prices.
 
     Principles of Consolidation -- The accompanying consolidated financial
statements include the accounts of Apache and its subsidiaries after elimination
of intercompany balances and transactions. The Company's interests in oil and
gas ventures and partnerships are proportionately consolidated. Certain
reclassifications have been made to the Consolidated Financial Statements for
prior years to conform with the current presentation. Apache's investment in
Producers Energy Marketing LLC (ProEnergy), a jointly-owned marketing company,
is accounted for using the equity method.
 
     Cash Equivalents -- The Company considers all highly liquid debt
instruments purchased with an original maturity of three months or less to be
cash equivalents. These investments are carried at cost, which approximates
market.
 
     Inventories -- Inventories consist principally of tubular goods and
production equipment, stated at the lower of weighted average cost or market,
and oil produced but not sold, stated at current market value net of costs to
sell.
 
     Property and Equipment -- The Company uses the full cost method of
accounting for its investment in oil and gas properties. Under this method, the
Company capitalizes all acquisition, exploration and development costs incurred
for the purpose of finding oil and gas reserves, including salaries, benefits
and other internal costs directly attributable to these activities. Exclusive of
field-level costs, Apache capitalized $12.8 million, $12.5 million and $14.6
million of internal costs in 1996, 1995 and 1994, respectively. Costs associated
with production and general corporate activities are expensed in the period
incurred. Internal costs attributable to the management of the Company's
producing properties, before recoveries from industry partners, totaled $17.0
million, $16.3 million and $13.2 million in 1996, 1995, and 1994, respectively,
and are included in operating costs in the Company's Statement of Consolidated
Income. Interest costs related to unproved properties and properties under
development are also capitalized to oil and gas properties. Unless a significant
portion of the Company's reserve volumes are sold (greater than 25 percent),
proceeds from the sale of oil and gas properties are accounted for as reductions
to capitalized costs, and gains or losses are not recognized.
 
     Apache computes the provision for depreciation, depletion and amortization
(DD&A) of oil and gas properties on a quarterly basis using the
unit-of-production method based upon production and estimates of proved reserve
quantities. Unevaluated costs and related capitalized interest costs are
excluded from the

                      APACHE CORPORATION AND SUBSIDIARIES
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
amortization base until the properties associated with these costs are
evaluated. The amortizable base includes estimated future development costs and
dismantlement, restoration and abandonment costs, net of estimated salvage
values. These future costs are generally estimated by engineers employed by
Apache.
 
     Apache limits, on a country-by-country basis, the capitalized costs of
proved oil and gas properties, net of accumulated DD&A, to the estimated future
net cash flows from proved oil and gas reserves, net of related tax effects,
discounted at 10 percent. If capitalized costs exceed this limit, the excess is
charged to DD&A expense. Included in the estimated future net cash flows are
Canadian provincial tax credits expected to be realized beyond the date at which
the legislation, under its provisions, could be repealed. To date, the Canadian
provincial government has not indicated an intention to repeal this legislation.
 
     The costs of certain unevaluated leasehold acreage, wells being drilled and
international concession rights are not being amortized. Costs not being
amortized are periodically assessed for possible impairments or reductions in
value. If a reduction in value has occurred, costs being amortized are increased
or a charge is made against earnings for those international operations where a
reserve base is not yet established.
 
     Buildings, equipment and gas gathering, transmission and processing
facilities are depreciated on a straight-line basis over the estimated useful
lives of the assets, which range from two to 20 years. Accumulated depreciation
for these assets totaled $36.6 million and $26.3 million at December 31, 1996
and 1995, respectively.
 
     Accounts Payable -- Included in accounts payable at December 31, 1996 and
1995, are liabilities of approximately $36.5 million and $48 million,
respectively, representing the amount by which checks issued, but not presented
to the Company's banks for collection, exceeded balances in applicable bank
accounts.
 
     Revenue Recognition -- Apache uses the sales method of accounting for
natural gas revenues. Under this method, revenues are recognized based on actual
volumes of gas sold to purchasers. The volumes of gas sold may differ from the
volumes to which Apache is entitled based on its interests in the properties.
Differences between volumes sold and volumes based on entitlements create gas
imbalances which are generally reflected as adjustments to reported gas reserves
and future cash flows in the Company's supplemental oil and gas disclosures.
Adjustments for gas imbalances totaled less than one percent of Apache's proved
gas reserves at December 31, 1996. Revenue is deferred and a liability is
recorded for those properties where the estimated remaining reserves will not be
sufficient to enable the underproduced owner to recoup its entitled share
through production.
 
     Hedging Activities -- Apache periodically enters into commodity derivatives
contracts and fixed-price physical contracts to manage its exposure to oil and
gas price volatility. Commodity derivatives contracts, which are usually placed
with major financial institutions that the Company believes are minimal credit
risks, may take the form of futures contracts, swaps or options. Realized gains
and losses from the Company's price risk management activities are recognized in
oil and gas production revenues when the associated production occurs. Estimates
of future cash flows related to derivatives contracts, based upon year-end
prices, and fixed-price physical contracts are reflected in future cash inflows
from proved reserves in the Company's supplemental oil and gas disclosures.
 
     The Company enters into various interest rate cap and swap agreements from
time to time with major financial institutions to manage its exposure to
fluctuations in market interest rates. Gains and losses on these activities are
recognized in interest expense in the period hedged by the agreements.
 
     Income Taxes -- The Company follows the liability method of accounting for
income taxes under which deferred tax assets and liabilities are recognized for
the future tax consequences of (i) temporary differences between the tax bases
of assets and liabilities and their reported amounts in the financial statements
and (ii) operating loss and tax credit carryforwards for tax purposes. Deferred
tax assets are reduced by a valuation

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
allowance when, based upon management's estimates, it is more likely than not
that a portion of the deferred tax assets will not be realized in a future
period.
 
     Foreign Currency Translation -- The U.S. dollar is considered the
functional currency for each of the Company's international operations, except
for the Canadian subsidiary whose functional currency is the Canadian dollar.
Translation adjustments resulting from translating the Canadian subsidiary's
foreign currency financial statements into U.S. dollar equivalents are reported
separately and accumulated in a separate component of shareholders' equity. For
other international operations, transaction gains or losses are recognized in
current net income and were not material in any of the periods presented.
 
     Net Income Per Common Share -- Amounts are based on the weighted average
number of shares of common stock outstanding. The effects of common stock
equivalents, which would include shares from the assumed conversion of the 3.93
percent notes, were either immaterial or not dilutive for each of the periods
presented. Furthermore, fully diluted net income per share, assuming conversion
of certain of the convertible debentures, was not significantly different than
primary net income per share for all periods presented.
 
     Stock-Based Compensation -- The Company accounts for employee stock-based
compensation using the intrinsic value method prescribed by Accounting
Principles Board (APB) Opinion No. 25, "Accounting for Stock Issued to
Employees" and related Interpretations. Accordingly, the issuance by the
Financial Accounting Standards Board of Statement of Financial Accounting
Standards (SFAS) No. 123, "Accounting for Stock-Based Compensation" in 1996 had
no effect on the Company's results of operations.
 
     Use of Estimates -- The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.
Significant estimates with regard to these financial statements include the
estimate of proved oil and gas reserve volumes and the related present value of
estimated future net revenues therefrom (see supplemental oil and gas
disclosures).
 
2. ACQUISITIONS AND DIVESTITURES
 
ACQUISITIONS
 
     On May 20, 1996, Apache acquired, for approximately $396.3 million, The
Phoenix Resource Companies, Inc. (Phoenix), an oil and gas company operating
primarily in the Arab Republic of Egypt, through a merger (Merger) which
resulted in Phoenix becoming a wholly-owned subsidiary of Apache. Pursuant to
the Merger Agreement, shares of Phoenix common stock then outstanding and
outstanding Phoenix stock options (which were assumed by Apache) were converted
into the right to receive (a) .75 shares of Apache common stock with any
fractional shares paid in cash, without interest, and (b) $4.00 in cash. As a
result, 12.2 million shares of Apache common stock, valued at $26 per share,
were issued and approximately $65 million was paid to former Phoenix
shareholders.
 
     In 1996, the Company also completed 62 tactical regional acquisitions for
cash consideration totaling $115.0 million. These acquisitions added
approximately 18.9 MMboe to the Company's reserves.
 
     In September 1995, Apache acquired substantially all of the oil and gas
assets of Aquila Energy Resources Corporation (Aquila) for approximately $210
million. The acquired assets included proved reserves totaling an estimated 157
Bcf of gas equivalent, approximately 107,000 developed and 49,000 undeveloped
net acres located primarily in Apache's Anadarko Basin and Gulf of Mexico core
areas, a five-year, four-month premium-price gas contract effective September 1,
1995, and non-operated interests in four gas processing plants. The gas contract
calls for Aquila Energy Marketing Corporation, a wholly owned subsidiary of

UtiliCorp United Inc., to purchase 20 to 25 MMcf of gas per day from Apache at a
price of $2.70 per Mcf in 1996, escalating to $3.20 per Mcf in the year 2000.
 
     On May 17, 1995, Apache acquired DEKALB Energy Company (DEKALB, now known
as DEK Energy Company), an oil and gas company engaged in the exploration for,
and the development of, crude oil and natural gas in Canada, through a merger
which resulted in DEKALB becoming a wholly owned subsidiary of Apache. Pursuant
to the merger agreement, 8.4 million shares of Apache common stock were
exchanged for the outstanding DEKALB stock and DEKALB employee stock options.
Merger costs of approximately $10 million were charged to expense in the second
quarter of 1995. The merger was accounted for as a "pooling of interests" and,
as a result, the Company's consolidated financial statements for periods prior
to the merger have been restated to include combined results with DEKALB.
 
     In connection with the DEKALB merger, the methods used by Apache and DEKALB
in computing DD&A expense of proved oil and gas properties were conformed to the
units-of-production method using physical units. This method was previously used
by DEKALB and in conforming the methods used, Apache adopted the
units-of-production method in lieu of the future gross revenue method. The
conforming adjustments for DD&A expense have been reflected retroactively in the
accompanying consolidated financial statements along with an adjustment to
DEKALB's previously recorded deferred tax valuation allowance for U.S. operating
loss carryforwards expected to be utilized by Apache in future periods. All
other adjustments are reclassifications to conform financial statement
presentation. Apache and DEKALB had no significant intercompany transactions
prior to the merger.
 
     A reconciliation of the previously separate results of Apache and DEKALB to
the restated combined results for 1994 is as follows:

     On March 1, 1995, Apache completed the acquisition of 315 oil and gas
fields from Texaco Exploration and Production Inc. (Texaco) for an adjusted
purchase price of $567 million. The Texaco properties included estimated proved
reserves at the effective date, after adjustment for the exercise of
preferential rights and properties excluded following due diligence, of
approximately 105 MMboe.
 
     In December 1994, Apache purchased substantially all of the U.S. oil and
gas properties of Crystal Oil Company (Crystal) for approximately $95.8 million.
The producing oil and gas properties acquired from Crystal are located primarily
along the Arkansas-Louisiana border and southern Louisiana. The acquisition also
included approximately 32,000 net undeveloped mineral acres in southern
Louisiana.
 
     Except for the DEKALB transaction, each transaction described above has
been accounted for using the purchase method of accounting and has been included
in the financial statements of Apache since the dates of acquisition.

DIVESTITURES
 
     In 1996, Apache received $30.1 million from the sale of non-strategic oil
and gas properties in a number of separate transactions.
 
     In September 1995, Apache closed the sale of non-strategic oil and gas
properties in its Rocky Mountain region for approximately $140 million net to
Apache. The assets included Apache's interests in 138 fields with approximately
1,600 active wells in Colorado, Montana, North and South Dakota, Utah and
Wyoming. The Company retained its interests in the Green River Basin of Colorado
and Wyoming and in the San Juan Basin of Colorado and New Mexico. Proceeds from
the sale of all oil and gas properties sold during 1995 totaled $271.9 million.
 
3. INVESTMENTS IN EQUITY SECURITIES
 
     At December 31, 1996, Apache had no investments in equity securities.
 
     The Company realized gross gains totaling $.8 million, $.9 million and $2.2
million from the sale of equity securities during 1996, 1995 and 1994,
respectively. Apache utilizes the average cost method in computing realized
gains or losses, which are included in other revenues in the accompanying
statement of consolidated income.

     On October 31, 1996, Apache replaced its existing $1 billion revolving bank
credit facility with a global credit arrangement (global credit facility) that
provides Apache with greater borrowing availability, increased tax efficiency
and a lower cost of bank debt. Consisting of three separate bank facilities tied
together by an intercreditor agreement, the new global credit facility adds
Apache's oil and gas reserve values in Australia and Canada to those in the U.S.
in determining the Company's borrowing capacity. The facilities consist of a
$125 million facility in each of Australia and Canada, and a $750 million
facility in the United States. In connection with securing the global credit
facility, the Company terminated the AEL acceptance facility and the Bank of
Montreal facility using funds available under the new facility. The maximum
amount available is subject to periodic redetermination of a borrowing base,
determined solely at the discretion of the banks, predicated upon the Company's
oil and gas reserve values and forecast rate of production. As of December 31,
1996, the borrowing base was $947 million and, adjusted for certain specified
debt balances totaling $733 million, the available borrowing capacity under its
global credit facility totaled $214 million. Under the terms of the global
credit facility as of December 31, 1996, the Company must (i) maintain a minimum
tangible net worth of $880 million, which is adjusted quarterly for subsequent
earnings and securities transactions, and (ii) maintain a ratio of (a) earnings
before interest, taxes, depreciation, depletion and

amortization to (b) consolidated interest expense of not less than 3.7:1. The
Company was in compliance with all financial covenants at December 31, 1996.
 
     The global credit facility is scheduled to mature on October 31, 2001, and
the agreement provides for perpetual one-year extensions as requested by the
Company, subject to the approval of the lenders. At the Company's option, the
interest rate is based on (i) the First National Bank of Chicago's base rate,
(ii) the London Interbank Offered Rate (LIBOR) plus a margin determined by the
Company's senior debt rating and its ratio of debt to total capitalization, or
(iii) the LIBOR rate plus a margin that is determined by competitive bids from
the participating banks. At December 31, 1996, the margin for committed loans
was .25 percent. The Company also pays an annual facility fee of .10 percent on
the total amount of each of the three facilities, which varies based upon the
Company's public senior debt rating.
 
     In November 1996, Apache issued $150 million principal amount, $149.2
million net of discount, of senior unsecured 7.625 percent debentures maturing
on November 1, 2096. The debentures are not redeemable prior to maturity.
However, Apache has the right to advance maturity, under certain conditions.
These debentures are governed by the same indenture that governs the Company's
two issues of 30 year notes.
 
     During February 1996, Apache issued $100 million principal amount, $99.6
million net of discount, of senior unsecured 7.7 percent notes due March 15,
2026. During April 1996, Apache issued an additional $180 million principal
amount, $178.5 million net of discount, of senior unsecured 7.95 percent notes
maturing on April 15, 2026. Neither issue of notes is redeemable prior to
maturity. The indenture governing the notes imposes certain restrictions on the
Company, including limits on Apache's ability to incur debt secured by certain
liens and its ability to enter into certain sale and leaseback transactions.
 
     The 6 percent convertible subordinated debentures due 2002 totaling $172.5
million were issued by Apache in January 1995 and are convertible at the option
of the holder into Apache common stock at a price of $30.68 per share, subject
to adjustment under certain circumstances.
 
     The 9.25 percent notes totaling $100 million were issued by Apache in May
1992 and are not redeemable prior to their maturity in June 2002. In December
1992, Apache issued the 3.93 percent convertible notes. The 3.93 percent notes
mature in November 1997, and are not redeemable prior to maturity; however, they
are convertible into Apache common stock at $27 per share, subject to adjustment
under certain circumstances. The 3.93 percent notes are classified as long-term
debt in the accompanying consolidated balance sheet, as the Company has the
ability and intent to replace them with additional long-term debt if they are
not converted into Apache common stock.
 
     The indentures for the 9.25 percent and 3.93 percent notes impose
substantially similar restrictions on the Company, including limits on the
Company's ability to incur debt secured by certain liens and on its ability to
enter into certain sale and leaseback transactions. Upon certain changes in
control of the Company, both issues are subject to mandatory repurchase (or
conversion at the option of the noteholders in the case of the 3.93 percent
notes).
 
     At December 31, 1996, the Company also had certain uncommitted money market
lines of credit which are used from time to time for working capital purposes.
As of December 31, 1996, an aggregate of $2 million was outstanding under such
credit lines.
 
     The DEKALB 9.875 percent notes mature on July 15, 2000. On October 25,
1996, Apache redeemed, at par, $22.1 million principal amount of DEKALB 10
percent notes. Such notes were due in 1998 and were redeemed using borrowings
under the Company's revolving bank credit facility.
 
     In 1996, the Company, acting through two of its Egyptian subsidiaries,
established $75 million of secured credit facilities with the International
Finance Corporation to finance development of its Qarun Concession in Egypt.
During the pre-completion phase of development operations, the Company
guarantees the credit facilities; following completion, the facilities are
secured only by assets associated with the Qarun Concession.

Interest is assessed at LIBOR plus a margin determined by several factors,
including the Company's public senior debt ratings, the Company's
debt-to-capitalization ratio, and whether or not development operations are in
the pre-completion phase. At December 31, 1996, outstanding borrowings under
these facilities totaled $54.75 million and the applicable margin over LIBOR was
..875 percent. A commitment fee equal to one-half of one percent per annum is
payable on the unused portion of the facilities. Repayment of amounts
outstanding under the facilities is contractually scheduled to commence on June
15, 1998, with semi-annual installments thereafter ending on December 15, 2002.
 
     In 1992, Apache established a $35 million banking facility on behalf of
Apache Offshore Investment Partnership. At December 31, 1996, the amount
outstanding under such facility was $2.35 million, of which Apache's share was
$.6 million. On January 31, 1997, the loan was repaid by the Partnership and the
facility terminated.
 
     As of December 31, 1996 and 1995, the Company had approximately $20.3
million and $19.3 million, respectively, of unamortized costs associated with
its various debt obligations. These costs are reflected as deferred charges in
the accompanying consolidated balance sheet and are being amortized over the
life of the related debt.
 
     In January 1997, the Company established a $300 million commercial paper
program. The program allows Apache to borrow funds for up to 270 days at
attractive interest rates. The commercial paper program is supported by
availability under the $750 million U.S. portion of the global credit facility.

     U.S. deferred taxes have not been provided on foreign earnings totaling
$104 million, which are permanently reinvested abroad. Presently, limited
foreign tax credits are available to reduce the U.S. taxes on such amounts if
repatriated.
 
     At December 31, 1996, the Company had U.S. Federal net operating loss
carryforwards of $179.1 million that will expire beginning in 1997, foreign net
operating loss carryforwards of $6.5 million that can be carried forward
indefinitely, and U.S. and foreign statutory depletion carryforwards totaling
$13.4 million that can be carried forward indefinitely. The Company has
alternative minimum tax (AMT) credit carryforwards of $9.1 million that can be
carried forward indefinitely but which can be used only to reduce regular tax
liabilities in excess of AMT liabilities. The Company has investment and other
tax credit carryforwards of $.9 million that will expire beginning in 1997,
which have been fully reserved through the valuation allowance.
 
6. ADVANCE FROM GAS PURCHASER
 
     In December 1994, Apache received $67.4 million from a purchaser as an
advance payment for future natural gas deliveries of 20,000 MMBtu per day over a
six-year period commencing January 1995. As a condition of the arrangement with
the purchaser, Apache entered into a gas price swap contract with a third party
under which Apache became a fixed price payor at identical volumes and at prices
starting at $1.81 per MMBtu in 1995 and escalating at $.10 per MMBtu per year
through the year 2000. The net result of these related transactions is that gas
delivered to the purchaser will be reported as revenue at prevailing spot prices
in the future with Apache realizing a $.05 per MMBtu premium associated with a
monthly fee to be paid by the purchaser. The Company, through its marketing
subsidiaries, may purchase gas from third parties to satisfy gas delivery
requirements of this arrangement. Contracted volumes relating to this
arrangement are included in the Company's supplemental oil and gas disclosures.
 
     This payment has been classified as an advance on the balance sheet and is
being reduced as gas is delivered to the purchaser under the terms of the
contract. At December 31, 1996 and 1995, $51.8 million and $60.3 million,
respectively, were still outstanding. Gas volumes delivered to the purchaser are
reported as revenue at prices used to calculate the amount advanced, before
imputed interest, minus or plus amounts paid or received by Apache applicable to
the price swap agreement. Interest expense is recorded based on a rate of 9 1/2
percent.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     Public Equity Offering -- In September 1995, Apache completed a public
offering of approximately 7.5 million shares of Apache common stock for net
proceeds of $195.5 million.
 
     Stock Option Plans -- At December 31, 1996, officers and certain key
employees have been granted options to purchase the Company's common stock under
employee stock option plans adopted in 1990 and 1995 and under certain
predecessor plans (collectively, the Stock Option Plans). Under the Stock Option
Plans, the exercise price of each option equals the market price of Apache's
common stock on the date of grant. Options generally become exercisable ratably
over a four-year period and expire after ten years. The Company may issue up to
4,119,163 shares of common stock under the Stock Option Plans, of which options
to acquire 1,231,050 shares of common stock remained available for grant at
December 31, 1996.
 
     On October 31, 1996, the Company established the 1996 Performance Stock
Option Plan (the Performance Plan) for substantially all full-time employees,
excluding officers and certain key employees. Under the Performance Plan, the
exercise price of each option equals the market price of Apache common stock on
the date of grant. All options become exercisable after nine and one-half years
and expire ten years from the date of grant; however, exercisability will be
accelerated if share price goals of $50 and $60 per share, respectively, are
attained before January 1, 2000. The Company may issue up to 1,300,000 shares of
common stock under the Performance Plan, of which options to acquire 272,190
shares of common stock remained available for grant at December 31, 1996.
 
     A summary of the status of the plans described above as of December 31,
1996, 1995, and 1994 and changes during the years then ended is presented in the
table and narrative below (shares in thousands):

    interest rates of 6.19 and 6.47 percent; (ii) expected lives of five years
    for the Stock Option Plans in both 1996 and 1995, and 2.5 years for the
    Performance Plan in 1996, (iii) expected volatility of 30.50 and 35.75
    percent, and (iv) expected dividend yields of 0.85 and 1.04 percent.

     The Company accounts for its stock-based compensation plans under APB
Opinion No. 25 and related Interpretations, under which no compensation cost has
been recognized for the Stock Option Plans or the Performance Plan. If
compensation costs for these plans had been determined in accordance with SFAS
No. 123, the Company's net income and net income per common share would
approximate the following pro forma amounts:

     The pro forma amounts shown above may not be representative of future
results because the SFAS No. 123 method of accounting has not been applied to
options granted prior to January 1, 1995.
 
     On October 31, 1996, subject to shareholder approval, the Company adopted
the 1996 Share Price Appreciation Plan (the Appreciation Plan) for officers and
certain key employees. The Appreciation Plan provides for awards denominated in
shares of Apache common stock to become payable upon attainment of share price
goals of $50 and $60 per share, respectively, before January 1, 2000. Between 30
and 50 percent of the award will be paid in cash at the market value of the
stock on the date of payment, and the balance (up to a total of 2,000,000 shares
in the aggregate) will be issued in Apache common stock. Generally, any payments
will be made in three installments over 36 months. When and if payments are
made, the Company will recognize compensation expense over the 36 month vesting
period equal to the value of the stock issued on the date the share price goal
is attained (i.e., $50 or $60 per share, as appropriate) and the actual amount
of cash paid. No compensation expense related to the Appreciation Plan has been
included in the pro forma amounts shown above. Additionally, the shares of
Apache common stock contingently issuable under the Appreciation Plan will be
excluded from the computation of net income per common share until the stated
share price goals of $50 and $60 per share, respectively, are attained.
 
     Preferred Stock -- The Company has five million shares of no par preferred
stock authorized, of which 25,000 shares have been "designated" Series A Junior
Participating Preferred Stock and authorized for issuance pursuant to certain
rights that trade with Apache common stock. There are no shares of preferred
stock issued and outstanding; however, shares of preferred stock are reserved
for issuance upon the exercise of the preferred stock purchase rights discussed
below.

     Rights to Purchase Preferred Stock -- In December 1995, the Company
declared a dividend of one right (a Right) for each outstanding share of Apache
common stock effective on January 31, 1996. Each Right entitles the registered
holder to purchase from the Company one ten-thousandth (1/10,000) of a share of
Series A Junior Participating Preferred Stock at a price of $100 per one
ten-thousandth of a share, subject to adjustment. The Rights are exercisable 10
calendar days following a public announcement that certain persons or groups
acquired 20 percent or more of the outstanding shares of Apache common stock or
10 business days following commencement of an offer for 30 percent or more of
the outstanding shares of Apache common stock. Unless and until the Rights
become exercisable, they will be transferred with and only with the shares of
Apache common stock. If the Company engages in certain business combinations or
a 20 percent shareholder engages in certain transactions with the Company, the
Rights become exercisable for Apache common stock or common stock of the
corporation acquiring the Company (as the case may be) at 50 of the then-market
price. Any Rights that are or were beneficially owned by a person who has
acquired 20 percent or more of the outstanding shares of Apache common stock and
who engages in certain transactions or realizes the benefits of certain
transactions with the Company will become void. The Company may redeem the
Rights at $.01 per Right at any time until 10 business days after public
announcement that a person has acquired 20 percent or more of the outstanding
shares of Apache common stock. The Rights will expire on January 31, 2006,
unless earlier redeemed by the Company. Unless the Rights have been previously
redeemed, all shares of Apache common stock issued by the Company will include
Rights.

(1) Includes $10.7 million and $(7.9) million at December 31, 1996 and 1995,
    respectively, for fixed-to-floating price swaps where there is an offsetting
    position with a physical contract. See Commodity Price Hedges below.
 
     The following methods and assumptions were used to estimate the fair value
of the financial instruments summarized in the table above. The carrying values
of trade receivables and trade payables included in the accompanying
Consolidated Balance Sheet approximated market value at December 31, 1996 and
1995.
 
     Cash and Cash Equivalents -- The carrying amounts approximated fair value
due to the short maturity of these instruments.
 
     Investment Securities -- The fair value of investments is based on quoted
market prices at year end.
 
     Long-Term Debt -- The fair values of the 9.25 percent, 9.875 percent and
7.95 percent notes and the 7.625 percent debentures are based on the quoted
market prices for those issues. The fair values of the 3.93 percent convertible
notes and the 7.7 percent notes are estimated based on quotes obtained from
private investment firms. The fair value of the six percent convertible
subordinated debentures is based upon estimates provided to the Company by
independent sources. The carrying amount of the bank debt approximates fair
value because the interest rates are variable and reflective of market rates.
 
     Interest Rate Instruments -- The Company periodically enters into various
financial instruments to manage its interest rate exposure. At December 31,
1996, the Company did not have any outstanding interest rate swap agreements.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     Foreign Currency Rate Contracts -- The Company periodically enters into
forward foreign currency exchange contracts to reduce the impact of foreign
currency fluctuations on operating results. At December 31, 1996, Apache did not
have any open forward foreign currency exchange contracts.
 
     Commodity Price Hedges -- Apache periodically enters into commodity
derivative contracts and fixed-price physical contracts to manage its exposure
to oil and gas price volatility. Commodity derivatives contracts, which are
usually placed with major financial institutions that the Company believes are
minimal credit risks, may take the form of futures contracts, swaps or options.
The derivative contracts call for Apache to receive, or make, payments based
upon the differential between a fixed and a variable commodity price as
specified in the contract. As a result of these activities, Apache recognized
hedging losses in 1996 and 1995 of $23.0 and $4.3 million, respectively, while
recognizing a gain of $5.7 million in 1994. The 1995 loss reflected a $9.3
million pre-tax charge to earnings resulting from the loss of correlation of New
York Mercantile Exchange (NYMEX) prices from actual wellhead prices for certain
positions in January through March 1996 production, reported as a reduction of
other revenues, offset by $5 million of commodity pricing gains which increased
1995 oil and gas production revenues. The 1996 hedging loss and the 1994 hedging
gain were recognized in oil and gas production revenues during each of the
respective years.
 
     Apache's consolidated balance sheet includes deferred credits totaling $3.2
million and $4.8 million at December 31, 1996 and 1995, respectively, for gains
realized on the early termination of commodity derivative contracts in 1996 and
prior years. These gains will be recognized as oil and gas production revenues
over periods ranging from one to 48 months as the hedged production occurs.
 
     The following table and notes thereto cover the Company's pricing and
notional volumes on open natural gas commodity derivative contracts as of
December 31, 1996:

(1) The Company has various contracts to supply gas at fixed prices. In order to
    lock in a margin on a portion of the volumes, the Company is a fixed price
    payor on swap transactions. The average physical contract price ranges from
    $2.34 in 1997 to $2.78 in 2000. The fair value of these hedges was $10.7
    million at December 31, 1996, with $1.7 million of this value relating to
    the arrangement discussed in Note 6.
 
     The Company had, as of December 31, 1996, entered into price swaps on oil
production under which the Company will receive a NYMEX fixed price, averaging
$21.09 per barrel, on 800 barrels of daily crude oil production over a
twelve-month period ending December 31, 1997. The fair value of oil hedges was a
$.4 million loss at December 31, 1996.
 
     In connection with the purchase of MW Petroleum Corporation in mid-1991,
the Company and Amoco Production Company (Amoco) entered into a hedging
agreement. Under the terms of this agreement, Amoco receives payments in the
event oil prices rise above specified reference prices for any year during the
eight-year period ending June 30, 1999, or in the event gas prices exceeded
specified reference prices for any year during the five-year period ending June
30, 1996. In the event price sharing payments are due to Amoco, the volumes
listed below would be doubled until Amoco recovers its net payments previously
made to Apache ($5.8 million through the contract year ended June 30, 1996) plus
interest.

10. COMMITMENTS AND CONTINGENCIES
 
     Litigation -- The Company is involved in litigation and is subject to
governmental and regulatory controls arising in the ordinary course of business.
It is the opinion of the Company's management that all claims and litigation
involving the Company are not likely to have a material adverse effect on its
financial position or results of operations.
 
     Environmental -- Apache, as an owner and operator of oil and gas
properties, is subject to various federal, state, local and foreign country laws
and regulations relating to discharge of materials into, and protection of, the
environment. These laws and regulations may, among other things, impose
liability on the lessee under an oil and gas lease for the cost of pollution
clean-up resulting from operations, subject the lessee to liability for
pollution damages and impose restrictions on the injection of liquids into
subsurface strata. Apache maintains insurance coverage which it believes is
customary in the industry, although it is not fully insured against all
environmental risks.
 
     As part of the Company's due diligence review for acquisitions, Apache
conducts an extensive environmental evaluation of purchased properties.
Depending on the extent of an identified environmental problem, the Company may
exclude a property from the acquisition, or agree to assume liability for
remediation of the property. As of December 31, 1996, Apache had a reserve for
environmental remediation of approximately $6.6 million. The Company is not
aware of any environmental claims existing as of December 31, 1996, which have
not been provided for or would otherwise have a material impact on its financial
position or results of operations. There can be no assurance, however, that
current regulatory requirements will not change, or past non-compliance with
environmental laws will not be discovered on the Company's properties.
 
     International Commitments -- The Company, through its subsidiaries, has
acquired or has been conditionally or unconditionally granted exploration rights
in Australia, Egypt, The People's Republic of China, Indonesia and the Ivory
Coast. In order to comply with the contracts and agreements granting these
rights, the Company, through various wholly owned subsidiaries, is committed to
expend approximately $306.0 million through 2000.
 
     Retirement and Deferred Compensation Plans -- The Company provides a
retirement/401(k) savings plan and a non-qualified retirement/savings plan for
employees. These plans allow participating employees to elect to contribute up
to 10 percent of their salaries, with Apache making matching contributions up to
a maximum of six percent of each employee's salary. In addition, the Company
annually contributes a percentage of each participating employee's compensation,
as defined, to the plan. Vesting in the Company's contributions occurs at the
rate of 20 percent per year. Additionally, DEKALB maintains a separate
retirement plan. Total expenses under all plans were $6.3 million, $7 million
and $5.8 million for 1996, 1995 and 1994, respectively. The unfunded liability
for all plans has been accrued in the consolidated balance sheet.

     Lease Commitments -- The Company has leases for office space and equipment
with varying expiration dates through 2007. Net rental expense was $6.5 million,
$5.2 million and $4.4 million for 1996, 1995 and 1994, respectively.
 
     ProEnergy -- ProEnergy's limited liability company agreement provides that
capital funding obligations, allocations of profit and loss and voting rights
are calculated based upon the members' respective throughputs of natural gas
sold to ProEnergy. Each member's liability with respect to future capital
funding obligations is subject to certain limitations. Natural gas throughputs
are calculated, profit distributed, and/or capital called on a quarterly basis.
As of December 31, 1996, the Company held an approximate 44 percent interest in
ProEnergy.
 
     As of December 31, 1996, minimum rental commitments under long-term
operating leases and long-term pipeline transportation commitments, ranging from
15 to 27 years, are as follows:

11. CUSTOMER INFORMATION
 
     Major Purchasers -- ProEnergy purchases accounted for 35 percent of the
Company's oil and gas revenues in 1996. Beginning with April 1996 production,
ProEnergy was the principal purchaser of Apache's domestic natural gas
production.
 
     Natural Gas Clearinghouse (NGC) was the principal purchaser of Apache's
spot market gas production from April 1990 through September 30, 1995. Sales to
NGC accounted for 27 percent and 37 percent of the Company's oil and gas
revenues in 1995 and 1994, respectively.
 
     Concentration of Credit Risk -- The Company's revenues are derived
principally from uncollateralized sales to customers in the oil and gas
industry; therefore, customers may be similarly affected by changes in economic
and other conditions within the industry. Apache has not experienced significant
credit losses on such sales.
 
     Sales of natural gas by Apache to ProEnergy are similarly uncollateralized.
Apache and the other members of ProEnergy have agreed to fund the reasonably
anticipated future capital needs of ProEnergy. In addition, effective January
31, 1996, ProEnergy entered into a $150 million, three-year revolving credit
facility with a syndicate of banks to finance its operations. ProEnergy is,
however, subject to the risks inherent in the natural gas marketing industry.

     Oil and Gas Reserve Information -- Proved oil and gas reserve quantities
are based on estimates prepared by the Company's engineers in accordance with
guidelines established by the Securities and Exchange Commission (SEC). The
Company's estimates of proved reserve quantities of its U.S., Canadian and
certain international properties are subject to review by Ryder Scott Company
Petroleum Engineers, independent petroleum engineers, while the proved reserve
quantities of the Company's Egyptian properties are reviewed by Netherland,
Sewell & Associates, Inc., independent petroleum engineers.
 
     There are numerous uncertainties inherent in estimating quantities of
proved reserves and projecting future rates of production and timing of
development expenditures. The following reserve data represents estimates only
and should not be construed as being exact.

     Future Net Cash Flows -- Future cash inflows are based on year-end prices
except in those instances where the sale of natural gas or oil is covered by
physical or derivative contract terms providing for higher or lower amounts.
Operating costs, production and ad valorem taxes and future development costs
are based on current costs with no escalation.
 
     The following table sets forth unaudited information concerning future net
cash flows for oil and gas reserves, net of income tax expense. Income tax
expense has been computed using expected future tax rates and giving effect to
tax deductions and credits available, under current laws, and which relate to
oil and gas producing activities. This information does not purport to present
the fair market value of the Company's oil and gas assets, but does present a
standardized disclosure concerning possible future net cash flows that would
result under the assumptions used.

     Impact of Pricing -- The estimates of cash flows and reserve quantities
shown above are based on year-end oil and gas prices, except in those cases
where future gas sales are covered by contracts at specified prices. Estimates
of future liabilities and receivables applicable to oil and gas commodity hedges
are reflected in future cash flows from proved reserves with such estimates
based on prices in effect as of the date of the reserve report. Fluctuations are
largely due to supply and demand perceptions for natural gas and volatility in
oil prices.
 
     Under SEC rules, companies that follow full cost accounting methods are
required to make quarterly "ceiling test" calculations. Under this test,
capitalized costs of oil and gas properties may not exceed the present value of
estimated future net revenues from proved reserves, discounted at 10 percent,
plus the lower of cost or fair market value of unproved properties, as adjusted
for related tax effects and deferred income taxes. Application of these rules
generally requires future production to be priced at the unescalated oil and gas
prices in effect at the end of each fiscal quarter and requires a writedown if
the "ceiling" is exceeded, even if prices declined for only a short period of
time.
 
     Many full cost companies, including Apache, are concerned about the impact
of prolonged unfavorable gas prices on their ceiling test calculations. A
deterioration of gas or oil prices from year-end levels could result in the
Company recording a non-cash charge to earnings related to its oil and gas
properties. The SEC may permit the exclusion of capitalized costs and present
value of recently acquired properties in performing ceiling test calculations.
Pursuant thereto, Apache, in 1995, requested waivers and the SEC granted two
separate one-year waivers with respect to the properties acquired from Texaco
and Aquila. Such waivers expired in 1996.

This Agreement is made this _____ day of __________, 1993, by and between the
Arab Republic of Egypt (hereinafter referred to as "A.R.E.") or as the
"GOVERNMENT"), THE EGYPTIAN GENERAL PETROLEUM CORPORATION, a legal entity
created by law No. 167 of 1958 as amended (hereinafter referred to as

                                   WITNESSETH

WHEREAS, the Arab Republic of Egypt, the Egyptian General Petroleum Corporation
and Phoenix Resources Company of Qarun and Apache Oil Egypt, Inc. have entered
into a Concession Agreement





<PAGE>   3


signed by virtue of law No. 113 of 1993 for Petroleum Exploration and
Exploitation in the Qarun Area, Western Desert.

WHEREAS, Contractor has applied for an amendment of the natural gas and LPG
Pricing provisions under such Concession agreement; and

WHEREAS, the Board of Directors of E.G.P.C., has approved such amendment, and
agreed to take the legal procedures required therefor.

Now, therefore, the parties hereto agree as follows:

                                   ARTICLE I

Article VII (c) (2) of the Concession Agreement signed by virtue of Law No. 113
of 1993 for Petroleum Exploration and Exploitation in the Qarun Area, Western
Desert, shall be deleted in its entirety, and shall be replaced by the
following:

         2-      Gas and LPG
         (i)     The Cost Recovery and Profit Shares of Gas subject to a Gas
                 Sales Agreement between E.G.P.C. and CONTRACTOR (as sellers)
                 and E.G.P.C. (as buyer) entered into pursuant to Article VII
                 (e) shall be valued, delivered to and purchased by E.G.P.C. at
                 a price determined monthly according to the following formula:

                 PG = 0.85 x     F     x H
                            -----------
                                      6
                            42.96 x 10
                 Where:
                 PG = the value of the Gas in U.S. Dollars per thousand cubic
                      feet (MCF).  
                 F =  a value in U.S. Dollars per metric ton of the Crude of 
                      Gulf of Suez blend "FOB Ras Shukheir" calculated

                      by referring to "Platt's Oilgram Price Report" during a
                      month under the heading "Spot Crude Price Assessment for
                      Suez Blend."  This value reflects the total averages of
                      the published high and low values for a barrel during such
                      month divided by the number of days in such month for
                      which such values were quoted.  The value per metric ton
                      shall be calculated on the basis of a conversion factor to
                      be agreed upon annually between E.G.P.C. and CONTRACTOR.

                 H =  the number of British Thermal Units (BTUs) per thousand 
                      cubic feet (MCF) of Gas.

                 In the event that the value of F cannot be determined because
                 Platt's Oilgram Price Report is not published at all during a
                 month, the Parties shall meet and agree the value of F by
                 reference to other published sources.  In the event that there
                 are no such published sources or if the value of F cannot be
                 determined pursuant to the foregoing for any other reason, the
                 Parties shall meet and agree a value of F.

                 Such evaluation of Gas under a formula providing for a fifteen
                 (15) percent discount is based upon delivery at the delivery
                 point specified in Article VII (e) 2(ii) below, and is to
                 enable E.G.P.C. to finance and maintain the portions of the
                 pipeline distribution system to be provided by E.G.P.C.

         (ii)    The Cost Recovery and Profit Shares of LPG produced from a
                 plant constructed and operated by or on behalf of E.G.P.C. and
                 CONTRACTOR shall be separately valued for Propane and Butane
                 at the outlet of such LPG plant according to the following
                 formula (unless otherwise agreed between E.G.P.C. and
                 CONTRACTOR):

                 PLPG =  0.95 PR - (J x 0.85     F     )
                                            -----------

                 Where:
                 PLPG =  LPG price (separately determined for Propane and 
                         Butane) in U.S. Dollars per metric ton. 
                 PR =    the average over a period of a month of the figures 
                         representing the mid-point between the high and low
                         prices in U.S. Dollars per metric ton quoted in
                         "Platt's LPGaswire" during such month for Propane and
                         Butane FOB Ex-Ref/Stor. West Mediterranean.

                 J =     BTU's removed from the Gas Stream by the LPG plant 
                         per metric ton of LPG produced.
                 F =     the same value as F under sub-paragraph (i) above.

                 In the event that Platt's LPGaswire is issued on certain days
                 during a month but not on others, the value of PR shall be
                 calculated using only those issued which are published during
                 such month.  In the event that the value of PR cannot be
                 determined because Platt's LPGaswire is not published at all
                 during a month, the Parties shall meet and agree the value of
                 PR by reference to other published sources.  In the event that
                 there are no other such published sources or if the value of
                 PR cannot be determined pursuant to the foregoing for any
                 other reason, the Parties shall meet and agree the value of PR
                 by reference to the value of LPG (Propane and Butane)
                 delivered FOB from the Mediterranean Area.

                 Such value of LPG is based upon delivery at the delivery point
                 specified in Article VII (e)(2)(iii) below.

         (iii)   The Prices of Gas and LPG so calculated shall apply during the
                 same month.

         (iv)    The Cost Recovery and Profit Shares of Gas and LPG disposed of
                 by E.G.P.C. and CONTRACTOR other than to E.G.P.C.  pursuant to
                 Article VII(e) shall be valued at their actual realized price.

                                   ARTICLE II

Except as amended by this Agreement, the Concession Agreement signed by virtue
of Law No. 113 of 1993, shall continue in full force and effect in accordance
with its terms.

               APACHE CORPORATION RETIREMENT/401(k) SAVINGS PLAN

     Apache Corporation ("Apache") maintains the Apache Corporation
Retirement/401(k) Savings Plan (the "Plan").  Pursuant to section 10.4 of the
Plan, Apache has retained the right to amend the Plan.  Apache hereby exercises
that right by substituting the following Appendix G for the existing Appendix G
to the Plan, effective as of January 1, 1996.

                                   Appendix G

                               Citation Oil & Gas

                                  Introduction

     Apache Corporation, MW Petroleum Corporation, and Apache Energy Resources
Corporation (collectively, "Apache Companies") and Citation 1994 Investment
Limited Partnership ("Citation 1994 Limited") entered into a certain purchase
and sale agreement entitled "Purchase and Sale Agreement by and between Apache
Corporation, MW Petroleum Corporation, and Apache Energy Resources Corporation
(Sellers) and Citation 1994 Investment Limited Partnership (Buyer)" whereby
Apache Companies sold certain properties to Citation 1994 Limited.  In
connection with this transaction, Citation 1994 Limited, through its general
partner, Citation Oil & Gas Corporation ("Citation"), hired certain employees
of Apache effective September 1, 1995 ("Transferred Employees").  In connection
with this transaction, certain Apache employees were terminated by Apache, but
were not hired by Citation ("Terminated Employees").

     This Appendix contains special provisions that apply to the Transferred
Employees and the Terminated Employees.  Capitalized terms in this Appendix
have the same meanings as those given them in the Plan.

                                    Vesting

     The Accounts of the Transferred Employees and the Terminated Employees
shall be fully vested as of September 1, 1995.

                                 Participation

     Notwithstanding section 2.1, if a Transferred Employee is rehired by
Apache or any Affiliated Entity, the Transferred Employee shall be eligible to
begin to make Participant Before-Tax Contributions, and shall be eligible to
participate in the Plan with respect to the 6% Company Mandatory Contribution,
on the date he or she again becomes a Covered Employee.  Notwithstanding
paragraph 3.1(b)(i), a sale of Company Stock from a Transferred Employee's
Accounts before he or she is rehired shall not, by itself, cause the
Transferred Employee's matching percentage to be less than 100%.

                                 Distributions

     While a Transferred Employee is employed by Citation or by any business
then treated as a single employer with Citation pursuant to Code section
414(b), 414(c), 414(m), or 414(o) (a "Current Citation Employee"), the Current
Citation Employee shall be treated as a Participant who has terminated
employment with Apache and Affiliated Entities for purposes of determining his
or her withdrawal options from his or her Company Contributions Account.  A
Current Citation Employee shall be treated as an Employee for purposes of
determining his or her withdrawal options from his or her Participant Before-
Tax Contributions Account.
<PAGE>   2
                                     Loans

     A Current Citation Employee may borrow from the Plan pursuant to section
7.2 only if he or she is a party in interest (within the meaning of ERISA
section 3(14)) with respect to the Plan.


                            -- END OF APPENDIX G --

               APACHE CORPORATION RETIREMENT/401(k) SAVINGS PLAN

     Apache Corporation ("Apache") maintains the Apache Corporation
Retirement/401(k) Savings Plan (the "Plan").  Pursuant to section 10.4 of the
Plan, Apache has retained the right to amend the Plan.  Apache hereby exercises
that right by amending the Plan, by adding the following Appendix H to the
Plan, effective as of January 1, 1996.

                                   Appendix H

                           Producers Energy Marketing

                                  Introduction

     Producers Energy Marketing LLC ("ProEnergy") was formed in 1995 to market
the production of Apache and other independent oil companies.  Initially,
Apache owned approximately 57% of ProEnergy.  Several employees of Apache were
transferred to ProEnergy between January 1, 1996 and March 31, 1996
("Transferred Employees").

     This Appendix contains special provisions that apply only to the
Transferred Employees.  Capitalized terms in this Appendix have the same
meanings as those given them in the Plan.

                                    Vesting

     The Accounts of each Transferred Employee shall be fully vested as of the
date he or she was transferred to ProEnergy.  If a Transferred Employee is
rehired by Apache or an Affiliated Entity, a new Company Contributions Account
shall be established for all Company Matching Contributions (other than QMACs)
and all Company Mandatory Contributions (other than QNECs) that are made on
behalf of the Participant as of any date after his or her rehire by Apache or
an Affiliated Entity.  Whenever any Participant becomes fully vested in two
separate Company Contributions  Accounts, those Accounts shall be merged into
one Company Contributions Account.

                                 Participation

     Notwithstanding section 2.1, if a Transferred Employee is rehired by
Apache or any Affiliated Entity, the Transferred Employee shall be eligible to
begin to make Participant Before-Tax Contributions, and shall be eligible to
participate in the Plan with respect to the 6% Company Mandatory Contribution,
on the date he or she again becomes a Covered Employee.  Notwithstanding
paragraph 3.1(b)(i), a sale of Company Stock from a Transferred Employee's
Accounts before he or she is rehired shall not, by itself, cause the
Transferred Employee's matching percentage to be less than 100%.

                              Transfer of Accounts

     The Committee is authorized to transfer the Accounts of any or all
Transferred Employees, without the consent of any Transferred Employee,
directly to a plan sponsored by ProEnergy that is designed to satisfy the
requirements of Code section 401(a).  The Committee is also authorized to
transfer the Accounts of any Participant who becomes employed by ProEnergy or
by any business then treated as a single employer with ProEnergy pursuant to

                                 Distributions

     While a Transferred Employee is employed by ProEnergy or by any business
then treated as a single employer with ProEnergy pursuant to Code section
414(b), 414(c), 414(m), or 414(o) (a "Current ProEnergy Employee"), the Current
ProEnergy Employee shall be treated as a Participant who has terminated
employment with Apache and Affiliated Entities for purposes of determining his
or her withdrawal options from his or her Company Contributions Account.  A
Current ProEnergy Employee shall be treated as an Employee for purposes of
determining his or her withdrawal options from his or her Participant
Before-Tax Contributions Account.

                                     Loans

     A Current ProEnergy Employee may borrow from the Plan pursuant to section
7.2 only if he or she is a party in interest (within the meaning of ERISA
section 3(14)) with respect to the Plan.  (Note:  a Current ProEnergy Employee
is a party-in-interest with respect to the Plan while Apache and Affiliated
Entities own, directly or indirectly, 50% or more of ProEnergy.)
Notwithstanding subsection 7.2(e), the loan repayments shall be not
accelerated, and the loan shall not be payable in full on the date the Borrower
ceases to be a party-in-interest, if the reason that the Borrower ceases to be
a party-in-interest is because Apache and Affiliated Entities decrease their
ownership of ProEnergy and its affiliated entities.

                     NON-QUALIFIED RETIREMENT/SAVINGS PLAN
                                       OF
                               APACHE CORPORATION



         Apache Corporation ("Apache") established the Non-Qualified
Retirement/Savings Plan of Apache Corporation (the "Plan") effective as of
November 16, 1989.  Apache is now restating the Plan in its entirety as of
January 1, 1997.

         Apache has also established the Apache Corporation Retirement/401(k)
Savings Plan, (the "Retirement/Savings Plan"), a profit sharing plan that
satisfies the qualification requirements of section 401(a) of the Internal
Revenue Code of 1986, as amended (the "Code"), and which contains a cash or
deferred arrangement that satisfies the requirements of Code section 401(k).

         Apache intends for this Plan to provide a select group of management
or highly compensated employees of the Company (as that term is defined in
Article I) with deferred retirement benefits, in addition to the retirement
benefits provided under the Retirement/Savings Plan, in consideration of the
valuable services provided by such employees to the Company and to induce such
employees to remain in the employ of the Company.  The Company intends that the
Plan shall not be treated as a "funded" plan for purposes of either the Code or
the Employee Retirement Income Security Act of 1974, as amended ("ERISA").


                                  ARTICLE I

1.02     Affiliated Entity

         "Affiliated Entity" means any legal entity that is treated as a single

1.03     Committee

2.01     Eligibility and Participation

         The Committee shall from time to time in its sole discretion select
         those employees of the Company who are eligible to participate in the
         Plan from those employees who are among a select group of management

2.02     Enrollment

         Employees who have been selected by the Committee to participate in
         the Plan shall complete the enrollment procedure specified by the
         Committee.  The enrollment procedure may include form(s) for the
         employee to (a) designate his beneficiary (pursuant to Section 5.03),
         (b) provide instructions regarding the investment of his Account
         (pursuant to Section 4.01), (c) make Deferred Contributions by
         entering into an Enrollment Agreement with the Company (pursuant to

         The Committee shall have the authority to determine that a Participant
         is no longer eligible to participate in the Plan.  No Company

         from an employee's Compensation after the Participant ceases to be
         eligible to participate in the Plan.  The determination of the
         Committee with respect to the termination of participation in the Plan
         shall be final and binding on all





                                      4
<PAGE>   8
         parties affected thereby.  Any benefits accrued hereunder, however, at
         the time the Participant becomes ineligible to continue participation,
         shall be distributable in accordance with the provisions of the Plan.


                                  ARTICLE III
                            CONTRIBUTION DEFERRALS

3.01     Participant Deferrals

         (a)     General.  A Participant may elect to defer a portion of his
                 Compensation by filing the appropriate Enrollment Agreement
                 with the Committee.  Deferred Contributions shall be deducted
                 through payroll withholding from the Participant's cash
                 Compensation payable by the Company.  Deferred Contributions
                 shall be credited to the Participant's Account on or about the
                 date the amount is withheld from the Participant's
                 Compensation.

         (b)     Initial Enrollment.  When an employee first becomes eligible
                 to participate in the Plan, pursuant to Section 2.01, the
                 Committee shall provide him with an enrollment form, which,
                 when properly completed and timely returned to the Committee
                 shall constitute an Enrollment Agreement.  To be effective,
                 the Enrollment Agreement must be completed and returned to the
                 Committee before the 31st day after the employee becomes
                 eligible to participate in the Plan.  The employee may elect
                 to defer up to 50% of each pay period's Compensation
                 (excluding bonuses) to this Plan (in addition to his
                 contributions to the Retirement/Savings Plan).  The Enrollment
                 Agreement shall be effective on the first day of the payroll
                 period after the Committee receives the completed Enrollment
                 Agreement.  The Enrollment Agreement shall be irrevocable for
                 the remainder of the Plan Year, except as provided in
                 Subsections 3.01(e) through 3.01(g).

         (c)     Continuing Enrollment.  An eligible employee may enter into a
                 new Enrollment Agreement for each Plan Year.  To be effective,
                 the Enrollment Agreement must be completed and returned to the
                 Committee by the deadline established by the Committee.  The
                 deadline must be before the first day of the Plan Year.  The
                 employee may elect to defer up to 50% of each pay period's
                 Compensation (excluding bonuses) to this Plan (in addition to
                 his contributions to the Retirement/Savings Plan).  The
                 Participant may also elect to defer an additional amount equal
                 to any corrective distribution made to him during the Plan
                 Year by the Retirement/Savings Plan, pursuant to the terms of
                 Article III of that plan.  The Enrollment Agreement shall be
                 irrevocable for the Plan Year, except as provided in
                 Subsections 3.01(e) through 3.01(g).  If a Participant fails
                 to timely complete a new Enrollment Agreement for the
                 following Plan Year, the Participant's old Enrollment
                 Agreement shall be extended for another Plan Year.

         (d)     Deferrals from Bonuses.  In addition to the Deferred
                 Contributions that are provided for in Subsections 3.01(b) and
                 3.01(c) above, a Participant may also elect to defer up to 75%
                 of any performance bonus by filing an Enrollment Agreement
                 with the Committee.  The Committee must receive the
                 Participant's signed Agreement by the date specified by the
                 Committee, which date shall be no later than the day before
                 the size of the bonus is determined.

         (e)     Suspension of Deferred Contributions Following a Hardship
                 Withdrawal.  A Participant's Deferred Contributions shall be
                 suspended as specified in Section 5.04 following a hardship
                 withdrawal from this Plan and shall also be suspended, for the
                 number of months required by Section 7.1 of the
                 Retirement/Savings Plan, following a hardship withdrawal from
                 that plan.  If the suspension extends beyond the end of the
                 Plan Year, the Participant may enter into an Enrollment
                 Agreement for the remainder of the following Plan Year,
                 provided that he completes the Enrollment Agreement and
                 returns it to the Committee before his suspension has ended.
                 If he does not timely complete a new Enrollment Agreement, his
                 prior Enrollment Agreement shall be reinstated for the
                 remainder of the new Plan Year.

         (f)     Participant Becomes Ineligible.  A Participant's Enrollment
                 Agreement shall be canceled immediately when he becomes
                 ineligible to participate in the Plan.

         (g)     Committee-Initiated Changes in Enrollment Agreement.  The
                 Committee may adjust any Participant's Enrollment Agreement
                 for the remainder of any Plan Year by reducing the amount of
                 the Participant's future Deferred Contributions, provided that
                 the Committee believes that such reduction will assist the
                 Retirement/Savings Plan in satisfying any legal requirement.

3.02     Company Deferrals

         The Company shall credit to a Participant's Account a matching
         contribution for each payroll period and a retirement-6 contribution
         for the Plan Year.  The matching contributions shall be credited on
         the last day of each pay period.  The retirement-6 contribution shall
         be credited on the last day of the Plan Year.  Company Deferrals shall
         begin to share in the investment earnings (or losses) at the time
         specified in Article IV.

         (a)     Matching Contribution.  The matching contribution for this
                 Plan shall be calculated each pay period, after the
                 Retirement/Savings Plan's matching contribution is calculated.
                 The "total match" each pay period shall be equal to the
                 "applicable percentage" multiplied by the Participant's "total
                 deferrals" for the pay period; the maximum total match for a
                 pay period is 6% of the pay period's Compensation.

                 The "total match" is equal to the matching contribution to the
                 Participant's Account in this Plan plus the Company Matching
                 Contribution allocated to the Participant's accounts in the
                 Retirement/Savings Plan.





                                      6
<PAGE>   10
                 The "applicable percentage" is equal to that pay period's
                 matching percentage in the Retirement/Savings Plan, as
                 determined under paragraph 3.1(b)(i) of that plan.

                 The "total deferrals" for a pay period are equal to (i) the
                 Participant's Deferred Contributions for the pay period,
                 including any Deferred Contributions from a bonus paid during
                 the pay period, plus (ii) the Participant's salary deferrals
                 to the Retirement/Savings Plan for the pay period.

         (b)     Retirement-6.  In order to receive an allocation of the
                 retirement-6 contribution, an employee must be eligible to
                 participate in the Plan on the last day of the Plan Year.  The
                 retirement-6 contribution shall be calculated each Plan Year
                 after the Company Mandatory Contribution is calculated in the
                 Retirement/Savings Plan for the Plan Year.  The sum of the
                 Participant's retirement-6 contribution in this Plan and his
                 Company Mandatory Contribution in the Retirement Savings Plan
                 shall be equal to 6% of the Participant's Compensation for the
                 Plan Year.


                                   ARTICLE IV
                    INVESTMENT OF DEFERRALS AND ACCOUNTING

4.01     Investments

         All amounts credited to a Participant's Account, together with the
         earnings thereon, shall be credited with income and loss as if
         invested in one or more investment alternatives selected by the
         Committee.  At such times and under such procedures as the Committee
         shall designate, each Participant shall have the right to elect among
         investment alternatives made available by the Committee, including
         without limitation the right to transfer all or a portion of the funds
         in the Participant's Account among such available investment
         alternatives.  The Committee shall give written notice to the
         Participants of the investment alternatives, if any, available to them
         for election.  The Committee may change, add to or subtract from the
         investment alternatives available at any time.  Nothing contained in
         this Section shall be construed to give any Participant any power or
         control to make investment directions or otherwise influence in any
         manner the investment and reinvestment of assets contained within any
         investment alternative, such control being at all times retained in
         the full discretion of the Committee.  Nothing contained in this
         Section shall be construed to require the Committee to make investment
         choices available to Participants, and in lieu thereof the investment
         alternative may be selected by the Committee.  Company Deferrals and
         Deferred Contributions may be deemed to remain uninvested for a
         reasonable period of time following payroll withdrawal, as determined
         from time to time by the Committee, without interest. Nothing
         contained in this Section shall be construed to require the Company or
         the Committee to fund any Participant's Account, and the investment
         alternatives discussed herein may be used solely as a means to
         establish income and loss without the actual funding of the
         Participants' Accounts.

         (c)     A Participant shall be fully vested in the portion of his Plan
                 Account that is attributable to Company Deferrals in the
                 following circumstances.

                 (i)      The Participant shall be fully vested if he attains
                          age 65 while employed by the Company or an Affiliated
                          Entity.

                 (ii)     The Participant shall be fully vested if he is hired
                          by the Company after attaining age 65.

                 (iii)    The Participant shall be fully vested if he incurs a
                          Disability while employed by the Company or an
                          Affiliated Entity.

                 (iv)     The Participant shall be fully vested if he dies
                          while employed by the Company or an Affiliated
                          Entity.

                 (v)      All Participants shall be fully vested if a "Change
                          in Control" occurs.  A "Change of Control" occurs
                          when an individual or legal entity, together with all
                          individuals and legal entities acting in concert with
                          such individual or legal entity, or any or all of
                          them, acquires more than 20% of Apache's outstanding
                          voting securities; except that a Change of Control
                          does not occur if, prior to the acquisition of more
                          than 20% of the voting securities, Apache's Board of
                          Directors by majority vote designates the individual
                          or legal entity as an approved

                          acquiror and resolves that a Change of Control will
                          not have occurred for purposes of this Plan.

                 (vi)     All Participants in the Plan who were employed by the
                          Company on July 1, 1992 became 100% vested with
                          respect to all Company Deferrals made to the Plan
                          prior to or as of July 1, 1992.  If a Participant was
                          not previously 100% vested, then the amount that
                          becomes 100% vested pursuant to this paragraph shall
                          be allocated to a special account and a new account
                          shall be established for all Company Deferrals made
                          with respect to such Participant subsequent to July
                          1, 1992.  Once any Participant becomes 100% vested in
                          both such accounts, the two separate accounts shall
                          be merged into one account.

                 (vii)    All Participants who were transferred to Producers
                          Energy Marketing LLC prior to April 1, 1996 became
                          fully vested.  This special vesting rule applies only
                          to the Participant's Account at the time of his
                          transfer.  If such a Participant was not previously
                          fully vested, returns to employment with the Company,
                          and recommences participation in the Plan, then the
                          amount that became 100% vested pursuant to this
                          paragraph shall be allocated to a special account and
                          a new account shall be established for all Company
                          Deferrals made with respect to such Participant after
                          his reemployment.  Once a Participant becomes 100%
                          vested in both such accounts, the two separate
                          accounts shall be merged into one account.

         (d)     When a Participant terminates employment, the portion of his
                 Account that is not then vested shall be forfeited
                 immediately.

5.02     Distribution After Termination of Employment

         While a Participant is employed by the Company or an Affiliated
         Entity, the only available distribution is a hardship withdrawal
         pursuant to Section 5.04.  Distributions after the Participant's death
         are discussed in Section 5.03.  All other distributions are discussed
         in this Section.

         (a)     Timing.  The Participant's vested Account shall be distributed
                 after the Participant terminates employment with the Company
                 and all Affiliated Entities.  If the Participant terminates
                 employment before July 1, distribution shall commence in the
                 Plan Year of employment termination, as soon as
                 administratively convenient after the termination of
                 employment.  If the Participant terminates employment on or
                 after July 1, distribution shall commence in the Plan Year
                 after the termination of employment, as soon as
                 administratively convenient.





                                      9
<PAGE>   13
         (b)     Form of Distribution.  The Participant's entire vested Account
                 shall be paid in one payment if (i) the vested Account is less
                 than $100,000 when the Participant terminated employment, or
                 (ii) the Participant terminates employment in 1996 or 1997.
                 Otherwise, the distribution shall be paid in one to ten annual
                 installments, as elected by the Participant subject to the
                 following restrictions.  The Participant shall make his
                 distribution election when he initially enrolls in the Plan,
                 except that Participants prior to January 1, 1997 shall make
                 their election no later than December 31, 1996.  Regardless of
                 the Participant's election, the minimum annual installment
                 payment shall be $100,000, or, if less, the Participant's
                 remaining Account balance.  Each installment will be equal to
                 the greater of (i) the minimum installment, or (ii) the vested
                 Account balance at the beginning of the Plan Year divided by
                 the number of remaining annual installments, except for the
                 final installment, which will be equal to the remaining
                 Account balance.  Installments will be paid as soon as
                 administratively convenient during the Plan Year.

                 For example, if the Participant had chosen 5 annual
                 installments, and terminates employment in February of 1999,
                 the unvested account balance shall be forfeited immediately;
                 his 1999 installment will be one-fifth of his January 1, 1999
                 vested Account balance; his 2000 installment will be
                 one-fourth of his January 1, 2000 Account balance; his 2001
                 installment will be one-third of his January 1, 2001 Account
                 balance; his 2002 installment will be one-half of his January
                 1, 2002 Account balance; and his final installment in 2003
                 will be the remainder of his Account balance.

         (c)     Reemployment.  If a Participant is reemployed by the Company
                 or an Affiliated Entity before he is paid his entire vested
                 Account balance, his payments from the Plan shall be
                 suspended.  Payments will resume after he again terminates
                 employment.  The number of remaining payments shall be the
                 number of annual payments originally chosen, less the number
                 of payments received before he was reemployed.  If the
                 Participant dies before receiving all installments, Section
                 5.03 shall apply.

5.03     Distributions After Participant's Death

         (a)     Each Participant shall designate one or more persons, trusts
                 or other entities as his beneficiary (the "Beneficiary") to
                 receive any amounts distributable hereunder at the time of the
                 Participant's death.  In the absence of an effective
                 beneficiary designation as to part or all of a Participant's
                 interest in the Plan, such amount shall be distributed to the
                 Participant's surviving spouse, if any, otherwise to the
                 personal representative of the Participant's estate.

         (b)     A beneficiary designation may be changed by the Participant at
                 any time and without the consent of any previously designated
                 Beneficiary.  However, if the Participant is married, his
                 spouse shall be his Beneficiary unless such spouse has





                                      10
<PAGE>   14
                 consented to the designation of a different beneficiary.  To
                 be effective, the spouse's consent must be in writing,
                 witnessed by a notary public, and filed with the Committee.
                 If a Participant has designated his spouse as a Beneficiary or
                 as a contingent beneficiary, and the Participant and that
                 spouse subsequently divorce, then the beneficiary designation
                 shall be void and of no effect with respect to such spouse on
                 the day such divorce is final.

         (c)     When a Participant dies, his remaining vested Account balance
                 shall be distributed to his Beneficiary as soon as
                 administratively possible after his death, regardless of the
                 payment schedule the Participant elected, and regardless of
                 whether installment payments had begun.

5.04     Hardship Distributions

         A Participant may request, and the Committee may approve or disapprove
         in its sole discretion, a withdrawal of part or all of the vested
         portion of the Participant's Account, subject to the following:

         (a)     The Participant must file a written request for withdrawal
                 with the Committee, along with such information as the
                 Committee may request for this purpose.  The Committee shall
                 review the information filed as soon as practicable after it
                 is received and shall promptly inform the Participant of the
                 results of the Committee's determination.

         (b)     Such withdrawal may be made only for the purpose of meeting an
                 unforeseeable emergency, which shall be defined as a severe
                 financial hardship to the Participant resulting from a sudden
                 and unexpected illness or accident of the Participant or of a
                 dependent (as defined in Section 152 of the Code) of the
                 Participant, loss of the Participant's property due to
                 casualty, or other similar extraordinary and unforeseeable
                 circumstances arising as a result of events beyond the control
                 of the Participant, and only if and to the extent other
                 resources which could alleviate such need are not reasonably
                 available to the Participant.

         (c)     An unforeseeable emergency shall be determined to exist by the
                 Committee based on all relevant facts and circumstances.

         (d)     If the Committee determines that a hardship exists, the
                 Participant must represent to the Committee by written
                 certification that the need cannot be relieved through
                 reimbursement or compensation by insurance or otherwise; by
                 liquidation of the Participant's assets, to the extent that
                 liquidation of such assets would not itself cause severe
                 financial hardship; or by cessation of deferrals under the
                 Plan and any other plans maintained by the Company.

         (e)     If the Committee is satisfied that the foregoing requirements
                 are satisfied and determines, in its sole discretion, to
                 permit a hardship withdrawal, it will





                                      11
<PAGE>   15
                 determine the amount of hardship withdrawal necessary to
                 satisfy the need of the Participant and will distribute such
                 amount to the Participant.

         (f)     The Participant's Deferred Contributions shall be suspended
                 for six months following the date of his hardship withdrawal
                 from this Plan.  If a Participant makes a hardship withdrawal
                 from this Plan and also makes a hardship withdrawal from the
                 Retirement/Savings Plan, the suspension period under this Plan
                 shall run concurrently with the suspension period under the
                 Retirement/Savings Plan, if any, and the suspension period
                 under this Plan shall be the longer of the suspension period
                 provided under the Retirement/Savings Plan or the six-month
                 suspension provided by this Plan.

5.05     Withholding

         The Plan shall withhold any taxes or other amounts that it is required
         to withhold pursuant to any applicable law.  The Committee may direct
         the Plan to withhold additional amounts from any payment, either
         because the Participant so requested or to repay the Participant's
         debt or obligation to the Company or Affiliated Entities.


                                  ARTICLE VI
                                ADMINISTRATION

6.01     The Committee -- Plan Administrator

         The Committee members for the Plan shall be the same committee members
         as for the Retirement/Savings Plan.

6.02     Committee to Administer and Interpret Plan

         The Committee shall administer the Plan and shall have all discretion
         and powers necessary for that purpose, including, but not by way of
         limitation, full discretion and power to interpret the Plan, to
         determine the eligibility, status and rights of all persons under the
         Plan and, in general, to decide any dispute.  The Committee shall
         direct the Company, the Trustee, or both, as the case may be,
         concerning distributions in accordance with the provisions of the
         Plan.  The Committee shall maintain all Plan records except records of
         any Trust.

6.03     Organization of Committee

         The Committee shall adopt such rules as it deems desirable for the
         conduct of its affairs and for the administration of the Plan.  It may
         appoint agents (who need not be members of the Committee) to whom it
         may delegate such powers as it deems appropriate, except that any
         dispute shall be determined by the Committee.  The Committee may make
         its determinations with or without meetings.  It may authorize one or
         more of its members or





                                      12
<PAGE>   16
         agents to sign instructions, notices and determinations on its behalf.
         The action of a majority of the Committee shall constitute the action
         of the Committee.

6.04     Indemnification

         The Committee and all of the agents and representatives of the
         Committee shall be indemnified and saved harmless by the Company
         against any claims, and the expenses of defending against such claims,
         resulting from any action or conduct relating to the administration of
         the Plan, except claims judicially determined to be attributable to
         gross negligence or willful misconduct.

6.05     Agent for Process

         The Committee shall appoint an agent of the Plan for service of all
         process.

6.06     Determination of Committee Final

         The decisions made by the Committee shall be final and conclusive on 
         all persons.


                                 ARTICLE VII
                                    TRUST

7.01     Trust Agreement

         The Company may, but shall not be required to, adopt a separate Trust
         Agreement for the holding, investment and administration of the funds
         contributed to Accounts under the Plan.  The Trustee shall maintain
         and allocate assets to a separate account for each Participant under
         the Plan.  The assets of any such Trust shall remain subject to the
         claims of the Company's general creditors in the event of the
         Company's insolvency.

7.02     Expenses of Trust

         The parties expect that any Trust created pursuant to Section 7.01
         will be treated as a "grantor" trust for federal and state income tax
         purposes and that, as a consequence, such Trust will not be subject to
         income tax with respect to its income.  However, if the Trust should
         be taxable, the Trustee shall pay all such taxes out of the Trust.
         All expenses of administering any such Trust shall be a charge against
         and shall be paid from the assets of such Trust.

                          AMENDMENT AND TERMINATION

8.01     Termination of Plan

         The Company expects to continue the Plan indefinitely, but each
         Company may terminate its participation in the Plan at any time, and
         Apache may terminate the entire Plan at any time.

8.02     Amendment

         Apache may amend the Plan at any time and from time to time,
         retroactively or otherwise, on behalf of all Companies, but no
         amendment shall reduce any vested benefit that has accrued on the
         effective date of the amendment.

         Each amendment shall be in writing.  Each amendment shall be approved
         by Apache's Board of Directors or by an officer of Apache Corporation
         who is authorized by Apache's Board of Directors to amend the Plan.
         Each amendment shall be executed by an officer of Apache to whom
         Apache's Board of Directors has delegated the authority to execute the
         amendment.


                                  ARTICLE IX
                                MISCELLANEOUS

9.01     Funding of Benefits -- No Fiduciary Relationship

         All benefits payable under the Plan shall be distributed in cash or in
         kind, in the discretion of the Committee.  Benefits shall be paid
         either out of the Trust or, if no Trust is in existence or if the
         assets in the Trust are insufficient to provide fully for such
         benefits, then such benefits shall be distributed by the Company out
         of its general assets.  Nothing contained in the Plan shall be deemed
         to create any fiduciary relationship between the Company and the
         Participants.  Notwithstanding anything herein to the contrary, to the
         extent that any person acquires a right to receive benefits under the
         Plan, such right shall be no greater than the right of any unsecured
         general creditor of the Company, except to the extent provided in the
         Trust Agreement, if any.

9.02     Right to Terminate Employment

         The Company may terminate the employment of any Participant as freely
         and with the same effect as if the Plan were not in existence.





                                      14
<PAGE>   18
9.03     Inalienability of Benefits

         No Participant shall have the right to assign, transfer, hypothecate,
         encumber or anticipate his interest in any benefits under the Plan,
         nor shall the benefits under the Plan be subject to any legal process
         to levy upon or attach the benefits for payment for any claim against
         the Participant or his spouse.  If, notwithstanding the foregoing
         provision, any Participant's benefits are garnished or attached by the
         order of any court, the Company may bring an action for declaratory
         judgment in a court of competent jurisdiction to determine the proper
         recipient of the benefits to be distributed pursuant to the Plan.
         During the pendency of the action, any benefits that become
         distributable shall be paid into the court as they become
         distributable, to be distributed by the court to the recipient it
         deems proper at the conclusion of the action.

9.04     Claims Procedure

         (a)     All claims shall be filed in writing by the Participant, his
                 spouse or the authorized representative of the claimant, by
                 completing such procedures as the Committee shall require.
                 Such procedures shall be reasonable and may include the
                 completion of forms and the submission of documents and
                 additional information.

         (b)     If a claim is denied, notice of denial shall be furnished by
                 the Committee to the claimant within 90 days after the receipt
                 of the claim by the Committee, unless special circumstances
                 require an extension of time for processing the claim, in
                 which event notification of the extension shall be provided to
                 the Participant or beneficiary and the extension shall not
                 exceed 90 days.

         (c)     The Committee shall provide adequate notice, in writing, to
                 any claimant whose claim has been denied, setting forth the
                 specific reasons for such denial, specific reference to
                 pertinent Plan provisions, a description of any additional
                 material or information necessary for the claimant to perfect
                 his claims and an explanation of why such material or
                 information is necessary, all written in a manner calculated
                 to be understood by the claimant.  Such notice shall include
                 appropriate information as to the steps to be taken if the
                 claimant wishes to submit his claim for review.  The claimant
                 or the claimant's authorized representative may request such
                 review within the reasonable period of time prescribed by the
                 Committee.  In no event shall such a period of time be less
                 than 60 days.  A decision on review shall be made not later
                 than 60 days after the Committee's receipt of the request for
                 review.  If special circumstances require a further extension
                 of time for processing, a decision shall be rendered not later
                 than 120 days following the Committee's receipt of the request
                 for review.  If such an extension of time for review is
                 required, written notice of the extension shall be furnished
                 to the claimant prior to the commencement of the extension.
                 The decision on review shall be furnished to the claimant.
                 Such decision shall be in writing and shall include specific
                 reasons for the decision, written in a manner calculated to be





                                      15
<PAGE>   19
                 understood by the claimant, as well as specific references to
                 the pertinent Plan provisions on which the decision is based.

9.05     Disposition of Unclaimed Distributions

         Each Participant must file with the Company from time to time in
         writing his post office address and each change of post office
         address.  Any communication, statement or notice addressed to a
         Participant at his last post office address on file with the Company,
         or if no address is filed with the Company, then at his last post
         office address as shown on the Company's records, will be binding on
         the Participant and his spouse for all purposes of the Plan.  The
         Company shall not be required to search for or locate a Participant or
         his spouse.

9.06     Distributions Due Infants or Incompetents

         If any person entitled to a distribution under the Plan is an infant,
         or if the Committee determines that any such person is incompetent by
         reason of physical or mental disability, whether or not legally
         adjudicated an incompetent, the Committee shall have the power to
         cause the distributions becoming due to such person to be made to
         another for his or her benefit, without responsibility of the
         Committee to see to the application of such distributions.
         Distributions made pursuant to such power shall operate as a complete
         discharge of the Company, the Trustee, if any, and the Committee.

9.07     Use and Form of Words

         When any words are used herein in the masculine gender, they shall be
         construed as though they were also used in the feminine gender in all
         cases where they would so apply, and vice versa.  Whenever any words
         are used herein in the singular form, they shall be construed as
         though they were also used in the plural form in all cases where they
         would so apply, and vice versa.

9.08     Headings

         Headings of Articles and Sections are inserted solely for convenience
         and reference, and constitute no part of the Plan.





                                      16
<PAGE>   20
9.09     Governing Law

         The Plan shall be construed in accordance with ERISA, the Code, and,
         to the extent applicable, the laws of the State of Texas excluding any
         conflicts-of-law provisions.

                              PLAN ADMINISTRATION

The Plan shall be administered by the Committee.  In accordance with the
provisions of the Plan, the Committee shall, in its sole discretion, select the
Participants from among the Eligible Employees, determine the Options to be
granted pursuant to the Plan, the time at which such Options are to be granted,
and establish such other terms and requirements as the Committee may deem

                                       3
<PAGE>   7



terms of the Plan.  The Committee shall determine the form or forms of the
Option Agreements with Participants which shall evidence the particular
provisions, terms, conditions, rights and duties of the Company and the
Participants with respect to Options granted pursuant to the Plan, which
provisions need not be identical except as may be provided herein.  The
Committee may from time to time adopt such rules and regulations for carrying
out the purposes of the Plan as it may deem proper and in the best interests of
the Company.  The Committee may correct any defect, supply any omission or
reconcile any inconsistency in the Plan, or in any agreement entered into
hereunder, in the manner and to the extent it shall deem expedient and it shall
be the sole and final judge of such expediency.  No member of the Committee
shall be liable for any action or determination made in good faith.  The
determinations, interpretations and other actions of the Committee pursuant to
the provisions of the Plan shall be binding and conclusive for all purposes and
on all persons.


                                   SECTION 4

                           STOCK SUBJECT TO THE PLAN

4.1      Number of Shares.  Subject to Section 7.1 and Section 4.3, one million
three hundred thousand (1,300,000) shares of Stock are authorized for issuance
under the Plan in accordance with its terms and subject to such restrictions or
other provisions as the Committee may from time to time deem necessary.  This
authorization may be increased from time to time by approval of the Board and
the stockholders of the Company if, in the opinion of counsel for the Company,
such stockholder approval is required.  Shares of Stock which may be issued
pursuant to the terms of the Options granted hereunder shall be applied to
reduce the maximum number of shares of Stock remaining available for use under
the Plan.  The Company shall at all times during the term of the Plan and while
any Options are outstanding retain as authorized and unissued Stock and/or
Stock in the Company's treasury, at least the number of shares from time to
time required under the provisions of the Plan, or otherwise assure itself of
its ability to perform its obligations hereunder.

4.2      Other Shares of Stock.  Any shares of Stock that are subject to an
Option which expires, is forfeited, is canceled, or for any reason is
terminated, and any shares of Stock that for any other reason are not issued to
a Participant or are forfeited shall automatically become available for use
under the Plan.

4.3      Adjustments for Stock Split, Stock Dividend, etc.  If the Company
shall at any time increase or decrease the number of its outstanding shares of
Stock or change in any way the rights and privileges of such shares by means of
the payment of a Stock dividend or any other distribution upon such shares
payable in Stock, or through a Stock split,





                                       4
<PAGE>   8



subdivision, consolidation, combination, reclassification or recapitalization
involving the Stock, then in relation to the Stock that is affected by one or
more of the above events, the numbers, rights and privileges of the following
shall be increased, decreased or changed in like manner as if they had been
issued and outstanding, fully paid and nonassessable at the time of such
occurrence: (i) the shares of Stock as to which Options may be granted under
the Plan; and (ii) the shares of the Stock then included in each outstanding
Option granted hereunder.

4.4      Dividend Payable in Stock of Another Corporation.  If the Company
shall at any time pay or make any dividend or other distribution upon the Stock
payable in securities or other property (except money or Stock), a
proportionate part of such securities or other property shall be set aside and
delivered to any Participant then holding an Option for the particular type of
Stock for which the dividend or other distribution was made, upon exercise
thereof.  Prior to the time that any such securities or other property are
delivered to a Participant in accordance with the foregoing, the Company shall
be the owner of such securities or other property, and in all other respects
shall be treated as the owner.  If securities or other property which have been
set aside by the Company in accordance with this Section are not delivered to a
Participant because an Option is not exercised, then such securities or other
property shall remain the property of the Company and shall be dealt with by
the Company as it shall determine in its sole discretion.

4.5      Other Changes in Stock.  In the event there shall be any change, other
than as specified in Sections 4.3 and 4.4 hereof, in the number or kind of
outstanding shares of Stock or of any stock or other securities into which the
Stock shall be changed or for which it shall have been exchanged, and if the
Committee shall in its discretion determine that such change equitably requires
an adjustment in the number or kind of shares subject to outstanding Options or
which have been reserved for issuance pursuant to the Plan but are not then
subject to an Option, then such adjustments shall be made by the Committee and
shall be effective for all purposes of the Plan and on each outstanding Option
that involves that particular type of stock for which a change was effected.

4.6      Rights to Subscribe.  If the Company shall at any time grant to the
holders of its Stock rights to subscribe pro rata for additional shares thereof
or for any other securities of the Company or of any other corporation, there
shall be reserved with respect to the shares then under Option to any
Participant of the particular class of Stock involved the Stock or other
securities which the Participant would have been entitled to subscribe for if
immediately prior to such grant the Participant had exercised his entire
Option.  If, upon exercise of any such Option, the Participant subscribes for
the additional shares or other securities, the Option Price shall be increased
by the amount of the price that is payable by the Participant for such
additional shares or other securities.





                                       5
<PAGE>   9



4.7      General Adjustment Rules.  No adjustment or substitution provided for
in this Section 4 shall require the Company to sell a fractional share of Stock
under any Option, or otherwise issue a fractional share of Stock, and the total
substitution or adjustment with respect to each Option shall be limited by
deleting any fractional share.  In the case of any such substitution or
adjustment, the total Option Price for the shares of Stock then subject to the
Option shall remain unchanged but the Option Price per share under each such
Option shall be equitably adjusted by the Committee to reflect the greater or
lesser number of shares of Stock or other securities into which the Stock
subject to the Option may have been changed.

4.8      Determination by the Committee, etc.  Adjustments under this Section 4
shall be made by the Committee, whose determinations with regard thereto shall
be final and binding upon all parties thereto.


                                   SECTION 5

                         REORGANIZATION OR LIQUIDATION

In the event that the Company is merged or consolidated with another
corporation and the Company is not the surviving corporation, or if all or
substantially all of the assets or more than 20 percent of the outstanding
voting stock of the Company is acquired by any other corporation, business
entity or person, or in case of a reorganization (other than a reorganization
under the United States Bankruptcy Code) or liquidation of the Company, and if
the provisions of Section 8 hereof do not apply, the Committee, or the board of
directors of any corporation assuming the obligations of the Company, shall, as
to the Plan and outstanding Options either (i) make appropriate provision for
the adoption and continuation of the Plan by the acquiring or successor
corporation and for the protection of any such outstanding Options by the
substitution on an equitable basis of appropriate stock of the Company or of
the merged, consolidated or otherwise reorganized corporation which will be
issuable with respect to the Stock, provided that no additional benefits shall
be conferred upon the Participants holding such Options as a result of such
substitution, and the excess of the aggregate Fair Market Value of the shares
subject to such Options immediately after such substitution over the Option
Price thereof is not more than the excess of the aggregate Fair Market Value of
the shares subject to such Options immediately before such substitution over
the Option Price thereof, or (ii) upon written notice to the Participants,
provide that all unexercised Options shall be exercised within a specified
number of days of the date of such notice or such Options will be terminated.
In the latter event, the Committee shall accelerate the exercise dates of
outstanding Options so that all Options become fully vested prior to any such
event.

                                   SECTION 6

                                 PARTICIPATION

Participants in the Plan receiving First Category Options may be any Eligible
Employee in the discretion of the Committee.  Participants in the Plan
receiving Second Category Options shall be those Eligible Employees who, in the
judgment of the Committee, are performing, or during the term of their
incentive arrangement are expected to perform, important services in the
management, operation and development of the Company or an Affiliated
Corporation, and contribute, or are expected to contribute, to the achievement
of the Company's long-term corporate economic objectives.  Upon determination
by the Committee that an Option is to be granted to a Participant, written
notice shall be given to such person, specifying the terms, conditions, rights
and duties related thereto.  Options shall be deemed to be granted as of the
date specified in the granting resolution of the Committee, which date also
shall be the date of the Option Agreement with the Participant.  In the event
of any inconsistency between the provisions of the Plan and any Option
Agreement, the provisions of the Plan shall govern.


                                   SECTION 7

                                    OPTIONS

7.1      Grants.  Each Participant may be granted only one Option under this
Plan.  Each Option granted by the Committee shall be evidenced by a written
agreement entered into by the Company and the Participant to whom the Option is
granted (the "Option Agreement"), which shall contain the terms and conditions
set out in this Section 7, as well as such other terms and conditions, not
inconsistent therewith, as the Committee may consider appropriate.

7.2      Option Agreements.  There shall be two categories of Options issued
under this Plan as follows:

         (a)     The first category of Option ("First Category") shall have a
total of two hundred (200) shares of Stock issuable to a Participant upon
exercise; and

         (b)     The second category of Option ("Second Category") shall vary
by Participant and, as to any Participant, shall have a total number of shares
of Stock issuable upon exercise which equals the sum of the Initial Amount and
the Final Amount.

For purposes of this Plan, the term "Initial Amount" means such number of
shares (rounded to the nearest full share) which equals not more than one (1)
times such





                                       7
<PAGE>   11



Participant's Base Salary divided by the difference between $50 and the Option
Price.  The term "Final Amount" means such number of shares (rounded to the
nearest full share) which equals not more than one and one-half (1.5) times
such Participant's Base Salary divided by the difference between $60 and the
Option Price.

7.3      Common Terms.  Subject to Section 7.2 and Section 7.5, each Option
Agreement entered into by the Company and the Participants shall contain at
least the following terms and conditions:

         (a)     Number of Shares.  Each Option Agreement shall set forth a
specified number of shares of Stock issuable upon exercise of the Option, as
determined by the Committee pursuant to Section 7.2 hereof.

         (b)     Price.  The exercise price (the "Option Price") at which each
share of Stock covered by an Option may be purchased shall be the price
specified in the granting resolution of the Committee.

         (c)     Duration.  Each Option Agreement shall state the period of
time, determined by the Committee, within which the Option may be exercised
(the "Option Period"), which in no event may be greater than ten (10) years.

         (d)     Vesting.  Subject to the provisions of Section 7.3(e) and
Section 7.3(f), each Option shall become exercisable in full on the date
occurring nine years and six months from the date of grant or such earlier date
as the Committee may determine.

         (e)     Acceleration.  Each Option may become exercisable earlier, in
increments, upon the occurrence of a Price Threshold Date as follows:

                 (i)      If the Initial Price Threshold Date occurs prior to
January 1, 2000:

                          (A)     One-half of the shares of Stock subject to
the First Category Options become immediately exercisable as of such date, and

                          (B)     The Initial Amount of shares of Stock subject
to each Second Category Option become immediately exercisable as of such date.

                 (ii)     If the Final Price Threshold Date occurs prior to
January 1, 2000, the remaining portion of shares of Stock under each category
of Option becomes immediately exercisable as of such date.

         (f)     Termination of Employment, Death, Disability, etc.  Subject to
the following provisions, each Option Agreement shall state that each Option
and the right to





                                       8
<PAGE>   12



acquire stock thereunder shall be subject to the condition that the Participant
has remained a full-time employee of the Company from the date of grant of an
Option until the applicable exercise date:

                 (i)      If the employment of the Participant by the Company
is terminated (which for this purpose means that the Participant is no longer
employed by the Company or by an Affiliated Corporation) within the Option
Period for any reason other than cause, the Participant's retirement on or
after attaining age 60, or the Participant's disability or death, the Option
may be exercised by the Participant within three months following the date of
such termination (provided that such exercise must occur within the Option
Period), but not thereafter.  In any such case, the Option may be exercised
only as to the shares as to which the Option had become exercisable on or
before the date of termination of the Participant's employment.  If the
employment of the Participant is terminated within the Option Period for cause,
as determined by the Company, any portion of any Option not previously
exercised in accordance with this Section 7 shall thereafter be void for all
purposes.  As used in this subsection, "cause" shall mean a gross violation, as
determined by the Company, of the Company's established policies and
procedures, provided that the effect of this subsection 7.3(f) shall be limited
to determining the consequences of a termination and that nothing in this
subsection shall restrict or otherwise interfere with the Company's discretion
with respect to the termination of any employee.

                 (ii)     If the Participant retires from employment by the
Company on or after attaining age 60, the Option may be exercised by the
Participant within 36 months following his or her retirement (provided that
such exercise must occur within the Option Period), but not thereafter.  In the
event of the Participant's death during such 36-month period, each Option may
be exercised by those entitled to do so in the manner referred to in (iv)
below.  In any such case:

                          (A)     If the Participant is holding a First
Category Option and the Participant's retirement occurs on or after January 1,
2000, the Option may be exercised as to all shares of Stock which are subject
to the Option, including an increment of the Option, if any, which had not
otherwise become exercisable on or before the date of the Participant's
retirement, or

                          (B)     If the Participant is holding a First
Category Option and the Participant's retirement occurs prior to January 1,
2000, the Option may be exercised only as to the shares of Stock as to which
the Option had become exercisable on or before the date of the Participant's
retirement, or





                                       9
<PAGE>   13



                          (C)     If the Participant is holding a Second
Category Option, the Option may be exercised only as to the shares of Stock as
to which the Option had become exercisable on or before the date of the
Participant's retirement.

                 (iii)    If the Participant becomes disabled (as determined
pursuant to the Company's Long-Term Disability Plan or any successor plan),
during the Option Period while still employed, or within the 36-month period
referred to in (ii) above, the Option may be exercised by the Participant or by
his or her guardian or legal representative, within twelve months following the
Participant's disability, or within the 36-month period referred to in (ii) if
applicable and if longer (provided that such exercise must occur within the
Option Period), but not thereafter.  In the event of the Participant's death
during such twelve-month period, each Option may be exercised by those entitled
to do so in the manner referred to in (iv) below.  In any such case, the Option
may be exercised only as to the shares of Stock as to which the Option had
become exercisable on or before the date of the Participant's disability.

                 (iv)     In the event of the Participant's death while still
employed by the Company, each Option of the deceased Participant may be
exercised by those entitled to do so under the Participant's will or under the
laws of descent and distribution within twelve months following the
Participant's death (provided that in any event such exercise must occur within
the Option Period), but not thereafter, as to all shares of Stock which are
subject to such Option, including any increment of the Option, if any, which
has not yet become exercisable at the time of the Participant's death.  In the
event of the Participant's death within the 36-month period referred to in (ii)
above or within the twelve-month period referred to (iii) above, each Option of
the deceased Participant that is exercisable at the time of death may be
exercised by those entitled to do so under the Participant's will or under the
laws of descent and distribution within twelve months following the
Participant's death or within the 36-month period referred to in (ii), if
applicable and if longer (provided that in any event such exercise must occur
within the Option Period).

         (g)     Transferability.  Each Option Agreement shall state that the
Option granted thereunder is not transferable by the Participant, except by
will or pursuant to the laws of descent and distribution, and that such Option
is exercisable during the Participant's lifetime only by him or her, or in the
event of the Participant's disability or incapacity, by his or her guardian or
legal representative.

         (h)     Exercise, Payments, etc.

                 (i)      Each Option Agreement shall provide that the method
for exercising the Option granted therein shall be by delivery to the Office of
the Secretary of the Company of written notice specifying the number of shares
of Stock with respect to





                                       10
<PAGE>   14



which such Option is exercised and payment of the Option Price.  Such notice
shall be in a form satisfactory to the Committee and shall specify the
particular Option (or portion thereof) which is being exercised and the number
of shares of Stock with respect to which the Option is being exercised.  The
exercise of the Option shall be deemed effective on the date such notice is
received by the Office of the Secretary and payment is made to the Company of
the Option Price (the "Exercise Date").  If requested by the Company, such
notice shall contain the Participant's representation that he or she is
purchasing the Stock for investment purposes only and his or her agreement not
to sell or otherwise distribute any Stock so purchased in any manner that is in
violation of the Securities Act of 1933, as amended, or any applicable state
law.  Such restriction, or notice thereof, shall be placed on the certificates
representing the Stock so purchased.  The purchase of such Stock shall take
place at the principal offices of the Company upon delivery of such notice, at
which time the Option Price shall be paid in full by any of the methods or any
combination of the methods set forth in (ii) below.  A properly executed
certificate or certificates representing the Stock shall be issued by the
Company and delivered to the Participant.  If certificates representing the
Stock are used to pay all or part of the Option Price, separate certificates
for the same number of shares of Stock shall be issued by the Company and
delivered to the Participant representing each certificate used to pay the
Option Price, and an additional certificate shall be issued by the Company and
delivered to the Participant representing the additional shares of Stock, in
excess of the Option Price, to which the Participant is entitled as a result of
the exercise of the Option.

                 (ii)     the Option Price shall be paid by any of the
following methods or any combination of the following methods:

                          (A)     in cash;

                          (B)     by personal, certified or cashier's check 
payable to the order of the Company;

                          (C)     by delivery to the Company of certificates
representing a number of shares of Stock then owned by the Participant, the
Fair Market Value of which equals the Option Price of the Stock purchased
pursuant to the Option, properly endorsed for transfer to the Company;
provided, however, that shares of Stock used for this purpose must have been
held by the Participant for such minimum period of time as may be established
from time to time by the Committee; for purposes of this Plan, the Fair Market
Value of any shares of Stock delivered in payment of the Option Price upon
exercise of the Option shall be the Fair Market Value as of the Exercise Date;
or

                          (D)     by delivery to the Company of a properly
executed notice of exercise together with irrevocable instructions to a broker
to deliver to the Company





                                       11
<PAGE>   15



promptly the amount of the proceeds of the sale of all or a portion of the
Stock or of a loan from the broker to the Participant necessary to pay the
Option Price.

7.4      Tax Withholding.  Each Option Agreement shall provide that, upon
exercise of the Option, the Participant shall make appropriate arrangements
with the Company to provide for the amount of additional tax withholding
required by Sections 3102 and 3402 or any successor section(s) of the Internal
Revenue Code and applicable state income tax laws.

7.5      Subsequent Option Agreements.  Following the initial grant of Options
in 1996, additional Participants may be designated by the Committee for grant
of Options substantially in accordance with the above terms and conditions,
subject to such changes and modifications to reflect the circumstances of any
subsequent grant as the Committee, in its discretion, deems appropriate.

7.6      Stockholder Privileges.  No Participant shall have any rights as a
stockholder with respect to any shares of Stock covered by an Option until the
Participant becomes the holder of record of such Stock. No adjustments shall be
made for dividends or other distributions or other rights as to which there is
a record date preceding the date on which such Participant becomes the holder
of record of such Stock.


                                   SECTION 8

                               CHANGE IN CONTROL

8.1      In General.  In the event of a change in control of the Company as
defined in Section 8.3 hereof, then the Committee may, in its sole discretion,
without obtaining stockholder approval, to the extent permitted in Section 12
hereof, take any or all of the following actions:

         (a)     accelerate the dates on which any outstanding Options become
exercisable or make all such Options fully vested and exercisable;

         (b)     grant a cash bonus award to any Participant in an amount
necessary to pay the Option Price of all or any portion of the Options then
held by such Participant;

         (c)     pay cash to any or all Participants in exchange for the
cancellation of their outstanding Options in an amount equal to the difference
between the Option Price of such Options and the greater of the tender offer
price for the underlying Stock or the Fair Market Value of the Stock on the
date of the cancellation of the Options; and

         (d)     make any other adjustments to the outstanding Options.





                                       12
<PAGE>   16



8.2      Limitation on Payments.  If the provisions of this Section 8 would
result in the receipt by any Participant of a payment within the meaning of
Section 280G or any successor section(s) of the Internal Revenue Code, and the
regulations promulgated thereunder, and if the receipt of such payment by any
Participant would, in the opinion of independent tax counsel of recognized
standing selected by the Company, result in the payment by such Participant of
any excise tax provided for in Sections 280G and 4999 or any successor
section(s) of the Internal Revenue Code, then the amount of such payment shall
be reduced to the extent required, in the opinion of independent tax counsel,
to prevent the imposition of such excise tax; provided, however, that the
Committee, in its sole discretion, may authorize the payment of all or any
portion of the amount of such reduction to the Participant.

8.3      Definition.  For purposes of the Plan, a "change in control" shall
mean any of the events specified in the Company's Income Continuance Plan or
any successor plan which constitute a change in control within the meaning of
such plan.


                                   SECTION 9

                       RIGHTS OF EMPLOYEES, PARTICIPANTS

9.1      Employment.  Nothing contained in the Plan or in any Option granted
under the Plan shall confer upon any Participant any right with respect to the
continuation of his or her employment by the Company or any Affiliated
Corporation, or interfere in any way with the right of the Company or any
Affiliated Corporation, subject to the terms of any separate employment
agreement to the contrary, at any time to terminate such employment or to
increase or decrease the level of the Participant's compensation from the level
in existence at the time of the grant of an Option.  Whether an authorized
leave of absence, or absence in military or government service, shall
constitute a termination of employment shall be determined by the Committee at
the time.

9.2      Nontransferability.  No right or interest of any Participant in an
Option granted pursuant to the Plan shall be assignable or transferable during
the lifetime of the Participant, either voluntarily or involuntarily, or
subjected to any lien, directly or indirectly, by operation of law, or
otherwise, including execution, levy, garnishment, attachment, pledge or
bankruptcy.  In the event of a Participant's death, a Participant's rights and
interests in Options shall, to the extent provided in Section 7 hereof, be
transferable by testamentary will or the laws of descent and distribution, and
payment of any amounts due under the Plan shall be made to, and exercise of any
Options may be made by, the Participant's legal representatives, heirs or
legatees.  If in the opinion of the Committee a person entitled to payments or
to exercise rights with respect to the Plan is





                                       13
<PAGE>   17



disabled from caring for his or her affairs because of mental condition,
physical condition or age, payment due such person may be made to, and such
rights shall be exercised by, such person's guardian, conservator or other
legal personal representative upon furnishing the Committee with evidence
satisfactory to the Committee of such status.


                                   SECTION 10

                              GENERAL RESTRICTIONS

10.1     Investment Representations.  The Company may require a Participant, as
a condition of exercising an Option, to give written assurances in substance
and form satisfactory to the Company and its counsel to the effect that such
person is acquiring the Stock subject to the Option for his own account for
investment and not with any present intention of selling or otherwise
distributing the same, and to such other effects as the Company deems necessary
or appropriate in order to comply with federal and applicable state securities
laws.

10.2     Compliance with Securities Laws.  Each Option shall be subject to the
requirement that, if at any time counsel to the Company shall determine that
the listing, registration or qualification of the shares of Stock subject to
such Option upon any securities exchange or under any state or federal law, or
the consent or approval of any governmental or regulatory body, is necessary as
a condition of, or in connection with, the issuance or purchase of shares of
Stock thereunder, such Option may not be accepted or exercised in whole or in
part unless such listing, registration, qualification, consent or approval
shall have been effected or obtained on conditions acceptable to the Committee.
Nothing herein shall be deemed to require the Company to apply for or to obtain
such listing, registration, qualification, consent or approval.


                                   SECTION 11

                            OTHER EMPLOYEE BENEFITS

The amount of any compensation deemed to be received by a Participant as a
result of the exercise of an Option shall not constitute "earnings" with
respect to which any other employee benefits of such Participant are
determined, including without limitation benefits under any pension, profit
sharing, life insurance or salary continuation plan.

                                   SECTION 12

                  PLAN AMENDMENT, MODIFICATION AND TERMINATION

The Board may at any time terminate, and from time to time may amend or modify
the Plan provided, however, that no amendment or modification may become
effective without approval of the amendment or modification by the Company's
stockholders if stockholder approval is required to enable the Plan to satisfy
any applicable statutory or regulatory requirements, or if the Company, on the
advice of counsel, determines that stockholder approval is otherwise necessary.

No amendment, modification or termination of the Plan shall in any manner
adversely affect any Option theretofore granted under the Plan, without the
consent of the Participant holding such Option.


                                   SECTION 13

                                  WITHHOLDING

13.1     Withholding Requirement.  The Company's obligations to deliver shares
of Stock upon the exercise of an Option shall be subject to the Participant's
satisfaction of all applicable federal, state and local income and other tax
withholding requirements.

13.2     Withholding with Stock.  At the time the Committee grants an Option,
it may, in its sole discretion, grant the Participant an election to pay all
such amounts of tax withholding, or any part thereof, by the transfer to the
Company, or to have the Company withhold from shares of Stock otherwise
issuable to the Participant upon the exercise of an Option, shares of Stock
having a value equal to the amount required to be withheld or such lesser
amount as may be elected by the Participant.  All such elections shall be
subject to the approval or disapproval of the Committee.  The value of shares
of Stock to be withheld shall be based on the Fair Market Value of the Stock on
the Exercise Date.  Any such elections by Participants to have shares of Stock
withheld for this purpose will be subject to the following restrictions:

         (a)     All elections shall be made on or prior to the Exercise Date.

         (b)     All elections shall be irrevocable.

         (c)     If, subsequent to the date of grant, the Participant becomes
an officer or director of the Company within the meaning of Section 16 or any
successor section(s) ("Section 16") of the Securities Exchange Act of 1934, as
amended (the "1934 Act"), the





                                       15
<PAGE>   19



Participant must satisfy the requirements of such Section 16 and any applicable
rules and regulations thereunder with respect to the use of Stock to satisfy
such tax withholding obligation.


                                   SECTION 14

                              REQUIREMENTS OF LAW

14.1     Requirements of Law.  The issuance of Stock and the payment of cash
pursuant to the Plan shall be subject to all applicable laws, rules and
regulations.

14.2     Federal Securities Laws Requirements.  If, subsequent to the date of
grant, a Participant becomes an officer or director of the Company within the
meaning of Section 16, Options granted hereunder shall be subject to all
conditions required under Rule 16b- 3, or any successor rule(s) promulgated
under the 1934 Act, to qualify the Option for any exemptions from the
provisions of Section 16 available under such Rule.  Such conditions are hereby
incorporated herein by reference and shall be set forth in the agreement with
the Participant which describes the Option.

14.3     Governing Law.  The Plan and all Option Agreements hereunder shall be
construed in accordance with and governed by the laws of the State of Texas.


                                   SECTION 15

                              DURATION OF THE PLAN

The Plan shall terminate at such time as may be determined by the Board, and no
Option shall be granted after such termination.  If not sooner terminated under
the preceding sentence, the Plan shall fully cease and expire at midnight on
December 31, 1998.  Options outstanding at the time of the Plan termination
shall continue to be exercisable in accordance with the Option Agreement
pertaining to such Option.

                        1990 EMPLOYEE STOCK OPTION PLAN

                                       OF

                      THE PHOENIX RESOURCE COMPANIES, INC.

                           (EFFECTIVE APRIL 9, 1990)

                     AS AMENDED THROUGH SEPTEMBER 29, 1995

     (AMENDED TO REFLECT JANUARY 1995 & SEPTEMBER 1995 TWO-FOR-ONE SPLITS)

1.       Purpose of the Plan.

         This 1990 Employee Stock Option Plan (the "Plan") is intended as an
         employment incentive, to retain in the employ of The Phoenix Resource
         Companies, Inc., a Delaware corporation (the "Company"), and any
         Parent or Subsidiary of the Company (within the meaning of Section
         425(e) or (f) of the Internal Revenue Code of 1986, as amended
         ("Code")), persons of training, experience and ability, to attract new
         employees, to encourage the sense of proprietorship of such persons
         and to stimulate the active interest of such persons in the
         development and financial success of the Company.  It is further
         intended that the options granted under the Plan will not be incentive
         stock options as that term is defined in Section 422A of the Code.

2.       Administration of the Plan.

         The Plan shall be administered by the Board of Directors, which shall
         serve as the Stock Option Committee (the "Committee"); provided,
         however, that any member of the Board of Directors who is eligible to
         receive options under the Plan, or any member of the Board of
         Directors who has, during the year preceding, been eligible to receive
         options under the Plan, shall not be a member of the Committee.  A
         majority of the Committee and a majority of the directors acting on
         any matter related to the Plan shall not have been eligible to
         participate in the Plan or any other plan of the Company or its
         affiliates which entitles participants to acquire stock, stock
         appreciation rights or stock options of the Company or its affiliates,
         other than the Company's 1990 Nonemployee Director Stock Option Plan
         (the "Director Plan"), at any time within the preceding twelve (12)
         months.  A majority of the Committee and a majority of the directors
         acting on any matter relating to the Plan shall not be eligible to
         receive stock options under this Plan ("Options") or any other plan of
         the Company or its affiliates which entitles participants to acquire
         stock, stock appreciation rights or stock options of the Company or
         its affiliates, other than the Director Plan, while serving on the
         Committee.  No director who is eligible to participate in the Plan
         shall take part in any Committee deliberations or action respecting
         the Plan related to such director.  The Committee shall have full
         power and authority to designate participants, to determine the terms
         and provisions of respective option agreements (which need not be
         identical) and to interpret the provisions and supervise the
         administration of the Plan.  All decisions and selections made by the
         Committee pursuant to the provisions of this Plan shall be made by a
         majority of its members.  Any decision reduced to writing and signed
         by all the members shall be fully effective as if it had been made by
         a majority at a meeting duly held.  The Committee shall have the
         authority to grant in its discretion to the holder of an outstanding
         Option in exchange for the surrender and cancellation of such Option,
         a new Option having a purchase price per share lower than provided in
         the Option so
<PAGE>   2
         surrendered and cancelled and containing such other terms and
         conditions as the Committee may prescribe in accordance with the
         provisions of the Plan.  All Options granted under this Plan are
         subject to, and may not be exercised before, the approval of the Plan
         by the stockholders of the Company pursuant to Rule 16b-3 of the
         Securities Exchange Act of 1934, as amended (the "Exchange Act").  For
         purposes of compliance with such rule, the entry of an order of
         confirmation of the bankruptcy plan of reorganization respecting the
         Company will constitute such stockholder approval.

3.       Designation of Participants.

         The persons eligible for participation in the Plan as recipients of
         Options shall include only employees of the Company or of any Parent
         or wholly-owned subsidiary of the Company.  Directors of the Company
         shall not be eligible to participate in the Plan as directors, but
         Directors otherwise qualified shall be eligible to participate.  An
         employee who has been granted an Option hereunder ("Optionee") may be
         granted an additional Option or Options, if the Committee shall so
         determine.

4.       Stock Reserved for the Plan.

         Subject to adjustment as provided in Paragraph 9 hereof, a total of
         one million, six hundred thousand (1,600,000) shares of Common Stock,
         par value $.01 per share ("Stock"), of the Company shall be subject to
         this Plan.  Pursuant to Amendment Number One of the Plan, approved by
         the stockholders at its 1995 Annual Meeting, an additional 600,000
         shares of Common Stock, par value $.01 per share, of the Company shall
         be subject to this Plan, subject to adjustment as provided in
         Paragraph 9 hereof.  The Shares subject to this Plan shall consist of
         unissued shares or previously issued shares reacquired and held by the
         Company, or any Parent or wholly-owned subsidiary of the Company, and
         such amount of shares shall be and is hereby reserved for such
         purpose.  Any of such shares which may remain unsold and which are not
         subject to outstanding Options at the termination of this Plan shall
         cease to be reserved for the purpose of this Plan, but until
         termination of this Plan the Company shall at all times reserve a
         sufficient number of shares to meet the requirements of this Plan.
         Should any Option expire or be cancelled prior to its exercise or
         relinquishment in full, the shares theretofore subject to such Option,
         to the extent it had not been exercised, may again be subjected to an
         Option under the Plan.

5.       Option Price.

         (a)     The purchase price of each share of Stock subject to an Option
                 shall be determined by the Committee prior to granting the
                 Option and shall not be less than the fair market value per
                 share of Stock on the date of the grant.

         (b)     The fair market value of a share on a particular date shall be
                 deemed to be (i) in the event the Stock is not listed on a
                 stock exchange or traded in the over-the-counter market, the
                 value determined in good faith by the Board of Directors of
                 the Company, which determination shall be conclusive, (ii) in
                 the event the Stock is listed on a national or regional stock
                 exchange, the closing sales price per share of the Stock on
                 such exchange on the date, or, if there shall have been no
                 sale on that date, on the last preceding date on which such a
                 sale or sales were so reported (the "Sale Date") or (iii) if
                 the Stock is traded in the over-the-counter market, the mean
                 between the highest closing bid and lowest




                                      2
<PAGE>   3
                 closing asked price for the Stock as reported by the National
                 Association of Securities Dealers Automated Quotation System
                 on the Sale Date, or if not reported by such system, the mean
                 between the closing bid and asked price on the Sale Date as
                 quoted by such quotation source as shall be designated by the
                 Committee.

6.       Option Period.

         Any Option granted under this Plan shall terminate and be of no force
         and effect with respect to any securities not previously taken up by
         the Optionee thereunder upon the expiration of the term of such Option
         as specified in the option agreement relating thereto, which term
         shall not exceed ten (10) years from the date of grant of such Option.

7.       Exercise of Options.

         (a)     The Committee, in granting Options hereunder, shall have
                 discretion to determine the terms upon which such Options
                 shall be exercisable, subject to the applicable provisions of
                 the Plan.  The Committee may determine to permit any Option
                 granted hereunder to be exercisable at any time after six (6)
                 months from the date of grant of such Option.

         (b)     Options may be exercised solely by the Optionee during his
                 lifetime or after his death by the personal representative of
                 the Optionee's estate or the person or persons entitled
                 thereto under his will or under the laws of descent and
                 distribution.

         (c)     The purchase price of the shares as to which an Option is
                 exercised shall be paid in full at the time of the exercise.
                 Such purchase price shall be payable in cash, or at the option
                 of the holder of such Option, in Stock theretofore owned by
                 such holder (or any combination of cash and such Stock).  For
                 purposes of determining the amount, if any, of the purchase
                 price satisfied by payment in Stock, such Stock shall be
                 valued at its fair market value on the date of exercise in
                 accordance with Paragraph 5(b) hereof.  Any Stock delivered in
                 satisfaction of all or a portion of the purchase price shall
                 be appropriately endorsed for transfer and assignment to the
                 Company.  No holder of an Option shall be, or have any of the
                 rights or privileges of, a stockholder of the Company in
                 respect of any shares purchasable upon the exercise of any
                 part of an Option unless and until certificates representing
                 such shares shall have been issued by the Company to such
                 holders.  The Company may make loans to the Optionees the
                 proceeds of which will be used to exercise the Options granted
                 pursuant to the Plan.  Although the terms of any such loans
                 will be determined on an individual basis, such loans will be
                 secured by a lien on the Stock to be purchased by the Optionee
                 and will bear interest at an interest rate to be determined on
                 the date the loan is made that is sufficient to avoid the
                 classification of the loan as a below-market loan under
                 Section 7872 of the Code.

8.       Relinquishment of Options; Assignability.

         (a)     The Committee, in granting Options hereunder, shall have
                 discretion to determine whether or not Options shall include a
                 right of relinquishment as hereinafter provided by this
                 Paragraph 8. The Committee shall also have discretion to
                 determine whether an option agreement evidencing an Option
                 granted by the Committee shall be amended or supplemented to
                 include such a right of relinquishment.  Neither the Committee
                 nor the Company shall be under any obligation or incur any
                 liability to any person by reason of





                                      3
<PAGE>   4
                 the Committee's refusing to grant or include a right of
                 relinquishment in any Option granted hereunder or in any
                 option agreement evidencing the same.  Subject to the
                 Committee's determining in any case that the grant by it of a
                 right of relinquishment is consistent with Paragraph 1 hereof,
                 any Option granted under the Plan, and the option agreement
                 evidencing such Option, may provide:

                 (i)      That the Optionee, or his heirs or other legal
                          representatives to the extent entitled to exercise
                          the Option under the terms thereof, in lieu of
                          purchasing the entire number of shares subject to
                          purchase thereunder, shall have the right to
                          relinquish all or any part of the then unexercised
                          portion of the Option (to the extent exercisable as
                          provided in (iv) hereinbelow) for a number of shares
                          of Stock, for an amount of cash or for a combination
                          of Stock and cash, to be determined as follows:

                          (A)     The written notice of exercise of such right
                                  of relinquishment, provided for in clause
                                  (ii) of this subparagraph (a), shall state
                                  the percentage, if any, of the Appreciated
                                  Value (as defined below), that such Optionee
                                  elects to receive in cash (which percentage
                                  is called the "Cash Percentage"), such Cash
                                  Percentage to be in increments of 10% of such
                                  Appreciated Value up to 100% thereof;

                          (B)     The number of shares of Stock of the Company,
                                  if any, issuable pursuant to such
                                  relinquishment shall be the number of such
                                  shares, rounded to the next greater number of
                                  full shares, as shall be equal to: 100% of
                                  the Appreciated Value less the Cash
                                  Percentage, multiplied by the excess of (1)
                                  the aggregate current market value of the
                                  shares of Stock covered by the Option or the
                                  portion thereof so relinquished over (2) the
                                  aggregate purchase price for such shares
                                  specified in such Option (which excess is
                                  called the "Appreciated Value"), divided by
                                  the then-current market value per share of
                                  such Stock; and

                          (C)     The amount of cash payable pursuant to such
                                  relinquishment shall be an amount equal to
                                  the Appreciated Value less the aggregate
                                  current market value of the Stock issued
                                  pursuant to such relinquishment, if any,
                                  which cash shall be paid by the Company
                                  subject to such conditions as are deemed
                                  advisable by the Committee to permit
                                  compliance by the Company with the
                                  withholding provisions applicable to
                                  employers under the Code (and under any
                                  applicable State income tax law);

                 (ii)     That such right of relinquishment may be exercised
                          only upon receipt by the Company of a written notice
                          of such relinquishment which shall be dated the date
                          of election to make such relinquishment; and that,
                          for the purposes of the Plan, such date of election
                          shall be deemed to be the date when such notice is
                          sent by registered or certified mail, or when receipt
                          is acknowledged by the Company, if mailed by other
                          than registered or certified mail or if delivered by
                          hand or by any telegraphic communications equipment
                          of the sender or otherwise delivered, provided that,
                          in the event the method described above for
                          determining such date of election shall not be or
                          remain consistent with provisions of Section 16(b) of
                          the Exchange Act or the rules and regulations adopted
                          by the Securities and

                          Exchange Commission thereunder, as presently existing
                          or as may be hereafter amended, which exempt from the
                          operation of said Section 16(b) in whole or in part
                          any such relinquishment transaction, then such date
                          of election shall be determined by such other method
                          consistent with said Section 16(b) or rules or
                          regulations as the Committee shall in its discretion
                          select and apply;

                 (iii)    That the "current market value" of a share on a
                          particular date shall be deemed to be its fair market
                          value on that date as determined in accordance with
                          Paragraph 5(b) hereof; and

                 (iv)     That the Option, or any portion thereof, may be
                          relinquished only to the extent that (A) it is
                          exercisable on the date written notice of
                          relinquishment is received by the Company and (B) the
                          Committee, subject to the provisions of Paragraph
                          8(b) hereof, shall consent to the election of the
                          holder of such Option to relinquish such Option as
                          set forth in such written notice of relinquishment,
                          and (C) the holder of such Option pays, or makes
                          provision satisfactory to the Company for the payment
                          of, any taxes which the Company is obligated to
                          collect with respect to such relinquishment.

         (b)     The Committee shall have sole discretion to consent to or
                 disapprove any election of a holder of an Option to relinquish
                 such Option for Stock and cash as provided in Paragraph 8(a)
                 hereof.  Neither the Committee nor the Company shall be under
                 any liability to any person by reason of the Committee's
                 disapproval of any election pursuant to this subparagraph (b).

         (c)     The Committee, in granting Options hereunder, shall have
                 discretion to determine the terms upon which such Options
                 shall be relinquishable, subject to the applicable provisions
                 of the Plan, and including such provisions as are deemed
                 advisable to permit the exemption from the operation from
                 Section 16(b) of the Exchange Act in whole or in part of any
                 such transaction involving such relinquishment, and Options
                 outstanding, and option agreements evidencing such Options,
                 may be amended, if necessary, to permit such exemption.  If an
                 Option is relinquished, such Option shall be deemed to have
                 been exercised to the extent of the number of shares of Stock
                 covered by the Option or part thereof which is relinquished,
                 and no further Options may be granted covering such shares of
                 Stock.

         (d)     Neither any Option nor any right to relinquish the same to the
                 Company as contemplated by this Paragraph 8 shall be
                 assignable or otherwise transferable except by will or the
                 laws of descent and distribution.

         (e)     No right of relinquishment may be exercised within the first
                 six months of the date of grant of such right; provided,
                 however, that this limitation shall not apply in the event of
                 death or disability.

9.       Capital Change of the Company; Certain Corporate Transactions.

         (a)     The existence of this Plan and Options granted hereunder shall
                 not affect in any way the right or power of the Company or its
                 stockholders to make or authorize any or all adjustments,
                 recapitalizations, reorganizations or other changes in the
                 Company's capital

                 structure or its business, or any merger or consolidation of
                 the Company, or any issue of bonds, debentures, preferred or
                 prior preference stocks ahead of or affecting the Company's
                 Stock or the rights thereof, or the dissolution or liquidation
                 of the Company, or any sale or transfer of all or any part of
                 its assets or business, or any other corporate act or
                 proceeding, whether of a similar character or otherwise.

         (b)     The shares with respect to which Options may be granted
                 hereunder are shares of the Stock of the Company as presently
                 constituted.  If, and whenever, prior to the delivery by the
                 Company of all of the shares of the Stock that are subject to
                 Options granted hereunder, the Company shall effect a
                 subdivision or consolidation of shares or other capital
                 readjustment, the payment of a stock dividend, a stock split,
                 combination of shares or recapitalization or other increase or
                 reduction of the number of shares of the Stock outstanding
                 without receiving compensation therefor in money, services or
                 property, the number of shares of Stock available under the
                 Plan and the number of shares of Stock with respect to which
                 Options granted hereunder may thereafter be exercised shall
                 (i) in the event of an increase in the number of outstanding
                 shares, be proportionately increased, and the cash
                 consideration payable per share with respect to Options then
                 issued and outstanding shall be proportionately reduced; and
                 (ii) in the event of a reduction in the number of outstanding
                 shares, be proportionately reduced, and the cash consideration
                 payable per share with respect to Options then issued and
                 outstanding shall be proportionately increased.

         (c)     Except as expressly provided herein, the issue by the Company
                 of shares of stock of any class, or securities convertible
                 into shares of stock of any class, for cash or property, or
                 for labor or services, either upon direct sale or upon the
                 exercise of rights or warrants to subscribe therefor, or upon
                 conversion of shares or obligations of the Company convertible
                 into such shares or other securities, shall not affect, and no
                 adjustment by reason thereof shall be made with respect to,
                 the number of shares of Stock subject to Options granted
                 hereunder.

         (d)     If the Company is reorganized, or merged or consolidated or
                 party to a plan of exchange with another corporation pursuant
                 to which reorganization, merger, consolidation, or plan of
                 exchange stockholders of the Company receive any shares of
                 Stock or other securities or if the Company shall distribute
                 ("Spin Off") securities of another corporation to its
                 stockholders, there shall be substituted for the shares
                 subject to the unexercised portions of outstanding Options an
                 appropriate number of shares of (i) each class of stock or
                 other securities which were distributed to the stockholders of
                 the Company in respect of such shares in the case of a
                 reorganization, merger, consolidation, or plan of exchange, or
                 (ii) in the case of a Spin Off, the securities distributed to
                 stockholders of the Company together with shares of Stock,
                 such number of shares or securities to be determined in
                 accordance with the provisions of Section 425 of the Code (or
                 other applicable provisions of the Code or regulations issued
                 thereunder which may from time to time govern the treatment of
                 incentive stock options in such a transaction).
                 Notwithstanding the foregoing, any unmatured installments of
                 the Options shall be accelerated and the Option shall
                 thereupon be exercisable in full without regard to any
                 installment exercise provision in the event of a Change of
                 Control (as defined below).

                 (i)      For purposes of this Plan, a Change of Control will 
                          occur when

                          (A)     any "person," including a "group" as
                                  determined in accordance with Section

                                  stockholders of the Company on April 9, 1990,
                                  or their respective affiliates within the

         alteration shall be made which, without the approval of the

                  1990 NONEMPLOYEE DIRECTOR STOCK OPTION PLAN

                                       OF

                      THE PHOENIX RESOURCE COMPANIES, INC.

                           (EFFECTIVE APRIL 9, 1990)

                     AS AMENDED THROUGH SEPTEMBER 29, 1995

     (AMENDED TO REFLECT JANUARY 1995 & SEPTEMBER 1995 TWO-FOR-ONE SPLITS)

1.       Purpose of the Plan.

         This 1990 Nonemployee Director Stock Option Plan (the "Plan") is
         intended as an incentive to retain as independent directors on the
         Board of Directors of The Phoenix Resource Companies, Inc., a Delaware
         corporation (the "Company"), persons of training, experience and
         ability, to attract new directors whose services are considered
         unusually valuable, to encourage the sense of proprietorship of such
         persons and to stimulate the active interest of such persons in the
         development and financial success of the Company.  It is further
         intended that the options issued pursuant to this Plan will not be
         incentive stock options as that term is defined in Section 422A of the
         Internal Revenue Code.

2.       Administration of the Plan.

         The Plan shall be administered by the Board of Directors, which shall
         serve as the Stock Option Committee (the "Committee").  No member of
         the Committee shall have been eligible to participate in any plan of
         the Company or its affiliates other than this Plan which entitles
         participants to acquire stock, stock appreciation rights or stock
         options of the Company or its affiliates at any time within the
         preceding twelve (12) months.  No member of the Committee shall be
         eligible to receive stock options under any other plan of the Company
         or its affiliates which entitles participants to acquire stock, stock
         appreciation rights or stock options of the Company or its affiliates
         while serving on the Committee, other than the options received under
         this Plan ("Options").  The Committee, exclusive of the Optionee (as
         defined below) with respect to such grant, shall have power, subject
         to the provisions of the Plan, to grant options under this Plan,
         determine the terms and provisions of respective option agreements
         (which need not be identical) and interpret the provisions and
         supervise the administration of the Plan.  All decisions and
         selections made by the Company pursuant to the provisions of the Plan
         shall be made by a majority of its members.  Any decision reduced to
         writing and signed by all of the members shall be fully effective as
         if it had been made by a majority at a meeting duly held.  The
         Committee shall have the authority to grant to all the holders of an
         outstanding Option in exchange for the surrender and cancellation of
         such Option, a new Option having a purchase price lower than provided
         in the Option so surrendered and cancelled and containing such other
         terms and conditions as the Committee may prescribe in accordance with
         the provisions of this Plan.  All Options granted under this Plan are
         subject to, and may not be exercised before, the approval of the Plan
         by the stockholders of the Company pursuant to Rule 16b-3 of the
         Securities Exchange Act of 1934, as amended (the "Exchange Act").

3.       Designation of Participants; Grant of Options.

         (a)     Each director of the Company who is not otherwise an employee
                 of the Company or of any Parent or Subsidiary ("Optionees")
                 shall be granted Options as described in this Plan.

         (b)     Each Optionee serving as a director of the Company immediately
                 following the 1994 Annual Meeting of Stockholders shall
                 automatically be granted Options to purchase 16,000 shares of
                 Stock.

         (c)     Each Optionee elected as a new member of the Board of
                 Directors of the Company subsequent to the 1994 Annual Meeting
                 of Stockholders shall automatically be granted Options to
                 purchase 12,000 shares of Stock.

         (d)     If at any time any Optionee owns Options to purchase less than
                 12,000 shares of Stock, then such Optionee shall automatically
                 be granted Options covering a sufficient number of shares of
                 Stock so that after such grant such Optionee would hold in the
                 aggregate, including all Options previously granted to such
                 Optionee that remain outstanding, Options covering 12,000
                 shares of Stock.

4.       Stock Reserved for the Plan.

         Subject to adjustment as provided in Paragraph 9 hereof, shares of
         Common Stock, par value $.001 per share ("Stock"), of the Company
         shall be subject to this Plan.  The Stock subject to this Plan shall
         consist of unissued shares or previously issued shares reacquired and
         held by the Company, or any Parent or wholly-owned subsidiary of the
         Company.  Initially, Three Hundred Thousand (300,000) shares of Stock
         shall be and are hereby reserved for such purpose.  Any of such shares
         that may remain unsold and that are not subject to outstanding Options
         at the termination of this Plan shall cease to be reserved for the
         purpose of the Plan, but until termination of the Plan the Company
         shall at all times reserve a sufficient number of shares to meet the
         requirements of the Plan.  Should any Option expire or be cancelled
         prior to its exercise or relinquishment in full, the shares
         theretofore subject to such Option may again be subjected to an Option
         under the Plan.

5.       Option Price.

         (a)     The purchase price of each share subject to a nonqualified
                 stock option under this Plan shall be the fair market value of
                 each share on the date the Option is granted.

         (b)     The fair market value of a share on a particular date shall be
                 deemed to be (i) in the event the Stock is not listed on a
                 stock exchange or traded in the over-the-counter market, the
                 value determined in good faith by the Board of Directors of
                 the Company, which determination shall be conclusive, (ii) in
                 the event the Stock is listed on a national or regional stock
                 exchange, the closing sales price per share of the Stock on
                 such exchange on the date, or, if there shall have been no
                 sale on that date, on the last preceding date on which such a
                 sale or sales were so reported (the "Sale Date") or (iii) if
                 the Stock is traded in the over-the-counter market, the mean
                 between the highest closing bid and lowest closing asked price
                 for the Stock as reported by the National Association of
                 Securities Dealers Automated Quotation System on the Sale
                 Date, or if not reported by such system,

                 the mean between the closing bid and asked price on the Sale
                 Date as quoted by such quotation source as shall be designated
                 by the Committee.

6.       Option Period.

         Options granted under this Plan shall terminate and be of no force and
         effect with respect to any shares not previously taken up by the
         Optionee upon the earliest to occur of the following: (a) the
         expiration of ten (10) years from the date of granting of each Option;
         (b) one year after the Optionee ceases to be a Director of the Company
         by reason of death or Disability (as hereinafter defined) of the

         Director of the Company for any reason other than death or Disability.
         For purposes of this Plan, Disability shall mean the inability of the
         Optionee for a period of six (6) months, or the expected inability of
         the Optionee for a period of six (6) months, substantially to perform
         his duties to the Company.

                 name of a deceased Optionee shall thereupon be exercisable in
                 full without regard to any installment exercise provisions.

         (e)     In the event the Optionee ceases his service as a Director of
                 the Company because of his attainment of age seventy (70) or
                 completion of ten (10) years of service as a Director
                 ("Retirement") while Options granted hereunder are still in
                 force and unexpired under the terms of Paragraph 6 hereof, any
                 unmatured installments of the Options shall be accelerated as
                 of the date of Retirement and the Option shall thereupon be
                 exercisable in full without regard to any installment exercise
                 provision.

         (f)     The purchase price of the shares as to which an Option is
                 exercised shall be paid in full at the time of the exercise.
                 Such purchase price shall be payable in cash, or at the option
                 of the holder of such Option, in Stock theretofore owned by
                 such holder (or any combination of cash and such Stock).  For
                 purposes of determining the amount, if any, of the purchase
                 price satisfied by payment in Stock, such Stock shall be
                 valued at its fair market value on the date of exercise in
                 accordance with Paragraph 5(b) hereof.  Any Stock delivered in
                 satisfaction of all or a portion of the purchase price shall
                 be appropriately endorsed for transfer and assignment to the
                 Company.  No holder of an Option shall be, or have any of the
                 rights or privileges of, a stockholder of the Company in
                 respect of any shares purchasable upon the exercise of any
                 part of an Option unless and until certificates representing
                 such shares shall have been issued by the Company to such
                 holders.  The Company may make loans to the Optionees the
                 proceeds of which will be used to exercise the Options granted
                 pursuant to the Plan.  Although the terms of any such loans
                 will be determined on an individual basis, such loans will be
                 secured by a lien on the Stock to be purchased by the Optionee
                 and will bear interest at an interest rate to be determined on
                 the date the loan is made that is sufficient to avoid the
                 classification of the loan as a below-market loan under
                 Section 7872 of the Internal Revenue Code of 1986, as amended
                 (the "Code").

8.       Relinquishment of Options; Assignability.

         (a)     Options granted hereunder shall include a right of
                 relinquishment as hereinafter provided by this Paragraph 8.
                 Any Option granted under the Plan, and the option agreement
                 evidencing such Option, shall provide:

                 (i)      That the Optionee, or his heirs or other legal
                          representatives to the extent entitled to exercise
                          the Option under the terms thereof, in lieu of
                          purchasing the entire number of shares subject to
                          purchase thereunder, shall have the right to
                          relinquish all or any part of the then unexercised
                          portion of the Option (to the extent exercisable as
                          provided in (iv) hereinbelow) for a number of shares
                          of Stock, to be determined as follows: The number of
                          shares of Stock of the Company, if any, issuable
                          pursuant to such relinquishment shall be the number
                          of such shares, rounded to the next greater number of
                          full shares, as shall be equal to: the Appreciated
                          Value, multiplied by the excess of (A) the aggregate
                          current market





                                      4
<PAGE>   5
                          value of the shares of Stock covered by the Option or
                          the portion thereof so relinquished over (B) the
                          aggregate purchase price for such shares specified in
                          such Option (which excess is called the "Appreciated
                          Value"), divided by the then-current market value per
                          share of such Stock; and

                 (ii)     That such right of relinquishment may be exercised
                          only upon receipt by the Company of a written notice
                          of such relinquishment which shall be dated the date
                          of election to make such relinquishment; and that,
                          for the purposes of the Plan, such date of election
                          shall be deemed to be the date when such notice is
                          sent by registered or certified mail, or when receipt
                          is acknowledged by the Company, if mailed by other
                          than registered or certified mail or if delivered by
                          hand or by any telegraphic communications equipment
                          of the sender or otherwise delivered, provided that,
                          in the event the method described above for
                          determining such date of election shall not be or
                          remain consistent with provisions of Section 16(b) of
                          the Exchange Act or the rules and regulations adopted
                          by the Securities and Exchange Commission thereunder,
                          as presently existing or as may be hereafter amended,
                          which exempt from the operation of said Section 16(b)
                          in whole or in part any election shall be determined
                          by such other method consistent with said Section
                          16(b) or rules or regulations as the Committee shall
                          in its discretion select and apply;

                 (iii)    That the "current market value" of a share on a
                          particular date shall be deemed to be its fair market
                          value on that date as determined in accordance with
                          Paragraph 5(b) hereof; and

                 (iv)     That the Option, or any portion thereof, may be
                          relinquished only to the extent that (A) it is
                          exercisable on the date written notice of
                          relinquishment is received by the Company and (B) the
                          holder of such Option pays, or makes provision
                          satisfactory to the Company for the payment of, any
                          taxes which the Company is obligated to collect with
                          respect to such relinquishment.

             (b) The Committee, in granting Options hereunder, shall have the
         power to amend any Options outstanding and option agreements
         evidencing such Options to include such provisions as are deemed
         advisable to permit the exemption from the operation from Section
         16(b) of the Exchange Act in whole or in part of any such transaction
         involving such relinquishment.  If an Option is relinquished, such
         Option shall be deemed to have been exercised to the extent of the
         number of shares of Stock covered by the Option or part thereof which
         is relinquished, and no further Options may be granted covering such
         shares of Stock.

             (c) Neither any Option nor any right to relinquish the same to the
         Company as contemplated by this Paragraph 8 shall be assignable or
         otherwise transferable except by will or the laws of descent and
         distribution.

9.       Capital Change of the Company; Certain Corporate Transactions.

         (a)     The existence of this Plan and Options granted hereunder shall
                 not affect in any way the night or power of the Company or its
                 stockholders to make or authorize any or all adjustments,
                 recapitalizations, reorganizations or other changes in the
                 Company's capital structure or its business, or any merger or
                 consolidation of the Company, or any issue of





                                      5
<PAGE>   6
                 bonds, debentures, preferred or prior preference stocks ahead
                 of or affecting the Company's Stock or the rights thereof, or
                 the dissolution or liquidation of the Company, or any sale or
                 transfer of all or any part of its assets or business, or any
                 other corporate act or proceeding, whether of a similar
                 character or otherwise.

         (b)     The shares with respect to which Options may be granted
                 hereunder are shares of the Stock of the Company as presently
                 constituted.  If, and whenever, prior to the delivery by the
                 Company of all of the shares of the Stock that are subject to
                 Options granted hereunder, the Company shall effect a
                 subdivision or consolidation of shares or other capital
                 readjustment, the payment of a stock dividend, a stock split,
                 combination of shares or recapitalization or other increase or
                 reduction of the number of shares of the Stock outstanding
                 without receiving compensation therefor in money, services or
                 property, the number of shares of Stock available under the
                 Plan and the number of shares of Stock with respect to which
                 Options granted hereunder may thereafter be exercised shall
                 (i) in the event of an increase in the number of outstanding
                 shares, be proportionately increased, and the cash
                 consideration payable per share with respect to Options then
                 issued and outstanding shall be proportionately reduced; and
                 (ii) in the event of a reduction in the number of outstanding
                 shares, be proportionately reduced, and the cash consideration
                 payable per share with respect to Options then issued and
                 outstanding shall be proportionately increased.

         (c)     Except as expressly provided herein, the issue by the Company
                 of shares of stock of any class, or securities convertible
                 into shares of stock of any class, for cash or property, or
                 for labor or services, either upon direct sale or upon the
                 exercise of rights or warrants to subscribe therefor, or upon
                 conversion of shares or obligations of the Company convertible
                 into such shares or other securities, shall not affect, and no
                 adjustment by reason thereof shall be made with respect to,
                 the number of shares of Stock subject to Options granted
                 hereunder.

         (d)     If the Company is reorganized, or merged or consolidated or
                 party to a plan of exchange with another corporation pursuant
                 to which reorganization, merger, consolidation, or plan of
                 exchange stockholders of the Company receive any shares of
                 Stock or other securities or if the Company shall distribute
                 ("Spin Off") securities of another corporation to its
                 stockholders, there shall be substituted for the shares
                 subject to the unexercised portions of outstanding Options an
                 appropriate number of shares of (i) each class of stock or
                 other securities which were distributed to the stockholders of
                 the Company in respect of such shares in the case of a
                 reorganization, merger, consolidation, or plan of exchange, or
                 (ii) in the case of a Spin Off, the securities distributed to
                 stockholders of the Company together with shares of Stock,
                 such number of shares or securities to be determined in
                 accordance with the provisions of Section 425 of the Code (or
                 other applicable provisions of the Code or regulations issued
                 thereunder which may from time to time govern the treatment of
                 incentive stock options in such a transaction).
                 Notwithstanding the foregoing, any unmatured installments of
                 the Options shall be accelerated and the Option shall be
                 exercisable in full without regard to any installment exercise
                 provision in the event of a Change of Control (as defined
                 below).

                 (i)      For purposes of this Plan, a Change of Control will 
                          occur when

                          (A)     any "person," including a "group" as
                                  determined in accordance with Section
                                  13(d)(3) of the Exchange Act is, or becomes
                                  the beneficial owner, directly or indirectly,
                                  of securities of the Company representing a
                                  Control Percentage (as defined below) of the
                                  combined voting power of the then outstanding
                                  securities of the Company;

                          (B)     as a result of, or in connection with, any
                                  tender offer or exchange offer, merger or
                                  other business combination, sale of assets or
                                  contested election, or any combination of the
                                  foregoing transactions (a "Transaction"), the
                                  persons who were Directors of the Company
                                  before the Transaction shall cease to
                                  constitute a majority of the Board of
                                  Directors of the Company, or any successor to
                                  the Company;

                          (C)     the Company is merged or consolidated with
                                  another corporation and as a result of such
                                  merger or consolidation a Control Percentage
                                  of the outstanding voting securities of the
                                  surviving or resulting corporation shall no
                                  longer be owned in the aggregate by the
                                  stockholders of the Company on April 9, 1990,
                                  or their respective affiliates within the
                                  meaning of the Exchange Act;

                          (D)     the Company transfers substantially all of
                                  its assets to another corporation that is not
                                  an affiliate of the Company.

                 (ii)     The term "Control Percentage" shall mean at least 25%
                          in the event the applicable securities are registered
                          under the Exchange Act or at least 40% in the event
                          the applicable securities are not registered under
                          the Exchange Act.

10.      Purchase for Investment.

         Unless the Options and shares covered by the Plan have been registered
         under the Securities Act of 1933, as amended, or the Company has
         determined that such registration is unnecessary, each person
         exercising an Option under the Plan may be required by the Company to
         give a representation in writing that he is acquiring such shares for
         his own account for investment and not with a view to, or for sale in
         connection with, the distribution of any part thereof.

11.      Taxes.

         The Company may make such provisions as it may deem appropriate for
         the withholding of any taxes which it determines is required in
         connection with any Options granted under the Plan.  In the event such
         provisions for withholding shall not be or remain consistent with
         provisions of Section 16(b) of the Exchange Act or the rules and
         regulations adopted by the Securities and Exchange Commission
         thereunder, as now existing or as may be hereafter amended, then
         provisions for withholding shall be determined by such other method
         consistent with the provisions of Section 16(b) or rules or
         regulations as the Committee shall select and apply.

12.      Effective Date of Plan.

         The Plan shall be effective as of April 9, 1990.

13.      Amendments or Termination.

         The Board of Directors may amend, alter or discontinue the Plan,
         except that no amendment or alteration shall be made which would
         impair the rights of any Optionee under any Option theretofore
         granted, without his consent, and except that no amendment or
         alteration shall be made which, without the approval of the
         stockholders, would:

       (a)       Increase or decrease the number of shares subject to Option or
                 the schedule of grants provided for in Paragraph 3; or

       (b)       Extend the option period provided for in Paragraph 6; or

       (c)       Materially increase the benefits accruing to Optionees under 
                 the Plan; or

       (d)       Materially modify the requirements as to eligibility for
                 participation in the Plan.

14.      Government Regulations.

         The Plan, and the granting and exercise of Options thereunder, and the
         obligation of the Company to sell and deliver shares under such
         Options, shall be subject to all applicable laws, rules and

         7.      Restrictive Covenant.  The Executive agrees that so long as
this Agreement is in full force and effect, he will not, directly or
indirectly, either as principal, agent, stockholder, or in any other capacity,
engage in or have a financial interest in, any business which is competitive to
the business of the Company and its subsidiaries, except that nothing contained
herein shall preclude the Executive from purchasing or owning stock in any such
business, providing that his holdings do not exceed one percent of the issued
and outstanding capital stock.  For the purposes hereof, a business will be
deemed competitive if it involves the production, manufacture or distribution
of any product similar to those produced, manufactured or distributed by the
company or any of its subsidiaries, or the rendering of any services similar to
those offered or rendered by the Company or any of its subsidiaries to members
of the public.  The Executive expressly agrees that upon a breach or violation

calculated on the basis of the compensation payable to the Executive under this
Agreement at the date of his death.  Such payments shall be made in equal
monthly installments over a period of five years from the date of the death of
the Executive.  If the Executive has no surviving spouse, then such amount
shall be paid to the Executive's estate in a lump sum.  If the Executive's
spouse survives him but dies before all of the aforementioned monthly payments
have been made, then the balance of such payments shall be paid to such
spouse's estate in a lump sum.

form of public insurance or benefit plan available to the Executive without
payment of premiums.

         13.     Successors. etc., of the Company.  This Agreement shall inure
to the benefit of and be binding upon the Company, its successors, and assigns,
including without limitation any person, partnership or corporation which may

                               FIRST AMENDMENT TO
                         RESTATED EMPLOYMENT AGREEMENT
                                       OF
                                 RAYMOND PLANK



         This First Amendment to that certain Restated Employment Agreement
dated December 5, 1990 (the "Restated Agreement"), by and between APACHE
CORPORATION, a Delaware corporation, with its principal offices located at 2000
Post Oak Boulevard, Suite 100, Houston, Texas  77056-4400 (hereinafter called
"Company"), and RAYMOND PLANK (hereinafter called the "Executive"), is made
this 4th day of April, 1996.




                                  WITNESSETH:


         WHEREAS, the Company and the Executive entered into a Restated
Agreement dated December 5, 1990; and

         WHEREAS, the parties desire to amend the terms and conditions of that
Restated Agreement;

         NOW, THEREFORE, it is mutually agreed by and between the parties
hereto that paragraph 9 of the Restated Agreement shall be deleted and replaced
in its entirety as follows:

         9.       Death.  In the event of the death of the Executive, the
                  Company shall pay to his designee, if any, or to his estate,
                  the amount of $750,000.00 in equal monthly installments over
                  10 years ($6,250.00 per month), commencing the first day of
                  the first month following the death of the Executive.  The
                  Executive may designate the recipient of these payments by
                  delivering to the Company, his written designation prior to
                  his death.  Such designation may be changed by the Executive
                  at any time prior to his death by executing and delivering to
                  the Company a subsequent written designation of recipient.
                  If the Executive has made no designation, then such amount
                  shall be paid to the Executive's estate in a lump sum.  If
                  the Executive's designee survives him, but dies before the
                  entire balance of monthly payments have been made, then the
                  balance shall be paid to such designee's estate in a lump
                  sum.
