CERTAIN DEFINITIONS
 
    As used herein, the following terms have the specific meanings set out:
'Bbl' means barrel. 'MBbl' means thousand barrels. 'MMBbl' means million
barrels. 'Mcf' means thousand cubic feet. 'MMcf' means million cubic feet. 'Bcf'
means billion cubic feet. 'BOE' means barrel of oil equivalent. 'MBOE' means
thousand barrels of oil equivalent and 'MMBOE' means million barrels of oil
equivalent. Natural gas volumes are converted to barrels of oil equivalent using
the ratio of 6.0 Mcf of natural gas to 1.0 barrel of crude oil. Unless otherwise
indicated, natural gas volumes are stated at the official temperature and
pressure basis of the area in which the reserves are located. 'Finding cost'
refers to a fraction, of which the numerator is equal to the costs incurred by
the Company for property acquisition, exploration and development and of which
the denominator is equal to proved reserve additions from extensions,
discoveries, improved recovery, acquisitions and revisions of previous
estimates. 'Improved recovery,' 'enhanced oil recovery' and 'EOR' include all
methods of supplementing natural reservoir forces and energy, or otherwise
increasing ultimate recovery from a reservoir, such as waterfloods, cyclic
steam, steam drive and CO2 (carbon dioxide) injection and fireflood projects.
'Heavy oil' is low gravity, high viscosity crude oil. 

ITEMS 1 AND 2.  BUSINESS AND PROPERTIES
 
GENERAL
 
    Santa Fe Energy Resources, Inc. ('Santa Fe' or the 'Company') is engaged in
the exploration, development and production of oil and natural gas in the
continental United States and in certain foreign areas. At December 31, 1993,
the Company had worldwide proved reserves totaling 292.0 MMBOE (consisting of
approximately 248.2 MMBbls of oil and approximately 263.0 Bcf of natural gas),
of which approximately 93% were domestic reserves and approximately 7% were
foreign reserves. During 1993, the Company's worldwide production aggregated
approximately 94.3 MBOE per day, of which approximately 71% was crude oil and
approximately 29% was natural gas. A substantial portion of the Company's
domestic oil production is in long-lived fields with well-established production
histories. With recent sales of non-core properties pursuant to the Company's
corporate restructuring program (see '-- Corporate Restructuring Program'), the
Company has focused its activities on its three domestic core areas -- the
Permian Basin in Texas and New Mexico, the offshore Gulf of Mexico and the San
Joaquin Valley of California -- as well as in Argentina and Indonesia.
 
    Santa Fe was incorporated in Delaware in 1971 as Santa Fe Natural Resources,
Inc., a wholly owned subsidiary of a predecessor of Santa Fe Pacific Corporation
('SFP'). SFP was formed as a result of a business combination on December 23,
1983, between Santa Fe Industries, Inc., the parent company of Santa Fe at that
time and Southern Pacific Company. On January 8, 1990, Santa Fe Energy Company,
which previously conducted a substantial portion of Santa Fe's domestic
exploration and development operations, merged into Santa Fe. Santa Fe
thereafter changed its name to Santa Fe Energy Resources, Inc. On March 8, 1990
Santa Fe sold 11,700,000 previously unissued shares of common stock in initial
public offerings. On December 4, 1990, SFP distributed all of the shares of
Santa Fe's common stock it held to its shareholders.
 
    In May 1992 Adobe Resources Corporation ('Adobe') was merged with and into
the Company (the 'Adobe Merger'). The location of the properties acquired in the
Adobe Merger (the 'Adobe Properties') enhanced the Company's existing domestic
operations and added significant international operations to the Company's
international program. See Note 3 to the Consolidated Financial Statements for
a further discussion of the Adobe Merger.
 
    For the five years ended December 31, 1993, the Company has replaced
approximately 172% of its production at an average finding cost of $4.80 per
BOE. Over the last four years, the Company has increased its overall production
by increasing production from its existing properties and through acquisitions
and has reduced its overall cost structure in order to enhance operating results
and to mitigate the Company's financial exposure in a low oil and natural gas
price environment. For example, over the four-year period ended December 31,
1993, Santa Fe has increased its average daily production from 69.1 MBOE to 94.3
MBOE (including 7.7 MBOE attributable to production from non-care assets sold
pursuant to the corporate restructuring program) and has reduced its average
production costs (including related production, severance and ad valorem taxes)
from $6.22 per BOE in 1990 to $5.39 per BOE in 1993.
 
    Most of the Company's domestic crude oil production is located in California
and Texas, while its domestic natural gas production comes primarily from the
Gulf of Mexico, New Mexico and Texas. During 1993, the Company's domestic daily
production averaged approximately 60.2 MBbls of crude oil and 165.0 MMcf of
natural gas. Substantially all of the Company's oil and gas production is sold
at market responsive prices. Pursuant to the corporate restructuring program,
during 1993 the Company sold properties having 1993 combined production of 4.1
MBbls per day and 21.7 MMcf per day and estimated proved reserves of
approximately 16.7 MMBOE. The domestic crude oil marketing activities of the
Company are conducted through its Santa Fe Energy Products Division ('Energy
 
                                       1
 
<PAGE>
Products'), which is also engaged in crude oil trading. Substantially all of the
Company's domestic natural gas production is currently marketed under the terms
of a sales contract with Hadson Corporation ('Hadson'). See '-- Current Markets
for Oil and Gas.'
 
    A substantial portion of the Company's domestic oil production is in
long-lived fields with well-established production histories and where EOR
methods are employed. As of December 31, 1993, approximately 69% of the
Company's domestic proved crude oil and liquids reserves and 50% of its 1993
average daily domestic production of crude oil and liquids were attributable to
the Midway-Sunset field in the San Joaquin Valley of California, where the
Company first began production in 1905. Nearly all of the reserves in this field
are heavy oil, the production of which depends primarily on steam injection. As
of December 31, 1993, an additional 21% of the Company's domestic proved crude
oil and liquids reserves and approximately 25% of its 1993 average daily
domestic production of crude oil and liquids were attributable to five other oil
producing properties: the Wasson and Reeves fields in the Permian Basin of west
Texas and the South Belridge, Kern River and Coalinga fields in the San Joaquin
Valley.
 
    The Company's foreign production is located in the El Tordillo field in
Argentina and in the Salawati Basin and Salawati Island area of Indonesia.
Production from the El Tordillo field averaged 2,400 barrels of oil per day in
1993 and production from the Indonesian operations averaged 4,100 barrels of oil
per day in 1993.
 
    The Company maintains an active exploration and development program, a
significant portion of which consists of EOR projects on the producing fields
discussed above. During 1993, Santa Fe spent a total of $100.2 million on EOR
and development programs and $50.5 million on exploration programs (including
$38.5 million of exploration costs, of which $31.0 million was charged to
expense, and $12.0 million of unproved property acquisition costs), and $32.6
million on proved property acquisitions. The Company has budgeted $240 million
of expenditures for 1994. However, as a result of depressed oil prices that have
prevailed since November 1993, the Company, consistent with industry practice,
is considering deferring some of its capital projects in order to prudently
manage its available cash flow in the near term. Based upon current market
conditions, the Company estimates that 1994 capital expenditures will total
between $100 million and $160 million, with the actual amount to be determined
by the Company based upon numerous factors outside its control, including,
without limitation, prevailing oil and natural gas prices and the outlook
therefor and the availability of funds.
 
    In the United States, at December 31, 1993, the Company held oil and gas
rights to approximately 0.8 million net undeveloped leasehold and fee acres in
14 states, excluding approximately 1.1 million net undeveloped acres sold to
Bridge under terms of a purchase agreement signed in December 1993 (expected to
close in April 1994) and 0.1 million net undeveloped fee acres sold to another
company in January 1994. See ' -- Corporate Restructuring Program.' Outside the
United States, at December 31, 1993, the Company held exploration rights with
respect to an aggregate of approximately 3.5 million net undeveloped acres in
Argentina, Bolivia, Canada, Gabon, Indonesia, Morocco, Myanmar and Papua New
Guinea.
 
CORPORATE RESTRUCTURING PROGRAM
 
    In October 1993 the Company's Board of Directors adopted a broad corporate
restructuring program designed to improve earnings and cash flow while
increasing production and replacing reserves in the long-term. The restructuring
program is the result of an intensive review of the Company's operations and
cash flows and focuses on capital spending in the Company's core operating areas
and the disposition of non-core assets. To provide additional funding for the
capital program, the Company also announced the elimination of the payment of
its $0.04 per share quarterly dividend on its common stock, which will make
available approximately $14 million annually. The dividend on the Company's
convertible preferred stock will remain at its current level.
 
                                       2
 
<PAGE>
 
    As a part of the Company's restructuring program, the Company intends to
concentrate its capital spending on its three domestic core areas -- the
Permian Basin in Texas and New Mexico, the offshore Gulf Coast and the
San Joaquin Valley of California -- as well as its productive
areas in Indonesia and Argentina. The domestic program includes
development activities in the Delaware formation in southeast New Mexico, a
development drilling program for the offshore Gulf of Mexico natural gas
properties and infill drilling in the San Joaquin Valley of California.
Internationally, the program includes development of the Company's Sierra Chata
discovery in Argentina with gas sales expected to commence in early 1995.
 
    The restructuring program includes an evaluation of the Company's capital
and cost structures to examine ways to increase flexibility and strengthen the
Company's financial performance. In this respect, in 1994 the Company intends to
refinance a portion of its existing long-term debt and is currently evaluating a
combination of debt and equity financing arrangements with which to effect the
refinancing.
 
    As a result of the dispositions described below (one of which is expected to
close in April 1994), the Company has sold properties having combined production
during 1993 of 4.1 MBbls per day and 21.7 MMcf per day and estimated proved
reserves of approximately 16.7 MMBOE for total proceeds of approximately $91.4
million, has sold its natural gas gathering and processing assets for Hadson
securities and has realized approximately $11.3 million from the sale of its
remaining Depositary Units in the Trust and $8.3 million from the sale of its
interest in certain other oil and gas properties. As a result of these
transactions, the Company has disposed of substantially all of its inventory of
non-core properties.
 
    SALE TO HADSON.  In December 1993 the Company completed a transaction with
Hadson under the terms of which the Company sold the common stock of Adobe Gas
Pipeline Company ('AGPC'), a wholly owned subsidiary, to Hadson in exchange for
Hadson 11.25% preferred stock with a face value of $52.0 million and 40% of
Hadson's common stock. In addition, the Company signed a seven-year gas sales
contract under the terms of which Hadson will market substantially all of the
Company's domestic natural gas production from specified existing wells and
certain domestic development and exploration wells. Pursuant to such contract,
Hadson will be required to pay the Company for all production delivered at a
price for such gas equal to stipulated published monthly index prices. See
'-- Current Markets for Oil and Gas'. The Company also designated one-half of
the members of the Hadson Board of Directors.
 
    AGPC's assets include approximately 630 miles of gathering and
transportation lines in Oklahoma, Texas and New Mexico with three processing
plants in west Texas and New Mexico and an intrastate pipeline system supplying
gas to commercial customers in Lubbock, Texas. Hadson's natural gas assets are
predominantly located in southeastern New Mexico and include two gas processing
facilities, a 12 Bcf natural gas storage facility and the 650-mile Llano
intrastate pipeline which has six connections to various interstate pipelines
serving strategic markets in the midwest, on the east coast and in southern
California.
 
    SALE TO VINTAGE.  In November 1993, the Company completed the sale of
certain southern California and Gulf Coast producing properties for net proceeds
totaling $41.3 million in cash. The transaction included most of the Company's
California interests outside its core area in the San Joaquin Valley as well as
certain onshore Gulf Coast properties in Texas, Louisiana and Mississippi.
Production from the properties sold to Vintage averaged approximately 2,800
barrels of oil per day and 6.5 MMcf of natural gas per day during 1993. During
1993 such properties contributed $2.7 million to the Company's income from
operations.
 
    SALE TO BRIDGE.  In December 1993, the Company signed a purchase agreement
with Bridge pursuant to which Bridge will purchase certain Mid-Continent and
Rocky Mountain producing and nonproducing oil and gas properties. The sales
price of $50.1 million, subject to certain adjustments, will be received by the
Company either in the form of cash plus 10% of the outstanding shares of
                                       
                                       3
 
<PAGE>
Bridge, following the contemplated public offering of that stock in the first
quarter of 1994, or entirely in cash. The transaction is expected to close in
April 1994.
 
    The transaction includes substantially all of the Company's assets in the
Anadarko Basin of Oklahoma and Texas as well as its interests in the Rocky
Mountain states, excluding its interests in the Canyon Creek natural gas field
in Wyoming. The undeveloped acreage includes approximately 1.7 million mineral
and leasehold acres and exploratory options on an additional 8.1 million acres.
Production from the properties to be sold to Bridge averaged approximately 1,300
barrels of oil per day and 15.2 MMcf of natural gas per day during 1993. During
1993 such properties contributed $5.8 million to the Company's income from
operations.

  (a) The information set forth under the column headed 'Changes in
      Ownership -- Partnership' reflects reserve additions attributable to the
      Company's increased ownership interest in Santa Fe Energy Partners, L.P.
      (the 'Partnership') caused by the reinvestment of distributions received
      by the Company in respect of its interest in the Partnership. At December
      31, 1993, the Company (through its subsidiaries) owned an aggregate 100%
      interest in the Partnership.

    Historically, the Company has utilized active development and exploration
programs as well as selected acquisitions to replace its reserves depleted by
production. The Company has increased its proved reserves (net of production) by
approximately 35% over the five years ended December 31, 1993. Most of such
increases are attributable to proved reserve additions from the Company's
producing oil properties in the San Joaquin Valley of California and the Permian
Basin in west Texas, proved reserves acquired in the Adobe Merger and other
purchases of oil and gas reserves. At December 31,

1993, the Company's reserves were 9.5 MMBOE lower than at December 31, 1992,
primarily reflecting the sale during 1993 of properties with reserves totaling
16.7 MMBOE partially offset by additions.

DOMESTIC DEVELOPMENT ACTIVITIES
 
    The Company is engaged in development activities primarily through the
application of thermal enhanced recovery techniques to its heavy oil properties
in the San Joaquin Valley, the use of secondary waterfloods and tertiary CO2
floods on its properties in other mature fields and the development of producing
properties acquired by the Company through its exploration successes and its
acquisition program. Thermal EOR operations involve the injection of steam into
a reservoir to raise the temperature and reduce the viscosity of the heavy oil,
facilitating the flow of the oil into producing wellbores. The Company has
operated thermal EOR projects in the San Joaquin Valley since the mid-1960s.
Similarly, the Company has extensive experience in the use of waterfloods, which
involve the injection of water into a reservoir to drive hydrocarbons into
producing wellbores. The Company has an interest in more than 50 waterflood
projects, and additional projects are planned for the future. Following the
waterflood phase, certain fields may continue to produce in response to tertiary
EOR projects, such as the injection of CO2 which mixes miscibly with the oil and
improves the displacement efficiency of the water injection. The Company's
principal CO2 floods are in the Wasson field and are operated by affiliates of
Shell Oil Company, ARCO and Amoco.
 
    Set forth below is a discussion of some of the Company's principal
development projects. The Company has operated in the Midway-Sunset and Wasson
fields since 1905 and 1939, respectively. The Company acquired interests in the
South Belridge field from Petro-Lewis in 1987 and in January 1991 expanded its
holdings in the field with the purchase of certain properties from Mission
Operating Partnership, L.P. The Company's interests in the Kern River and
Coalinga fields were acquired in 1905 and 1977, respectively. The Gulf of Mexico
fields were discovered on leases held by
 
                                       5
 
<PAGE>
the Company or acquired in the Adobe Merger, while the Delaware and Cisco
Canyon properties were acquired as undeveloped properties.
 
    SAN JOAQUIN VALLEY
 
    MIDWAY-SUNSET.  The Company owns a 100% working interest (92% average net
revenue interest) in over 10,000 gross acres and 2,200 active wells in the
Midway-Sunset field. Substantially all the oil produced from the Midway-Sunset
field is heavy crude oil produced principally by cyclic steam and steamflood
operations from Pleistocene and Miocene reservoirs at depths less than 2,000
feet. These steam stimulation operations were initiated in the field in the
mid-1960s. During 1993 the Midway-Sunset field accounted for approximately 50%
of the Company's domestic crude oil and liquids production.
 
    At December 31, 1993 the Midway-Sunset field accounted for approximately 69%
of the Company's domestic proved crude oil and liquid reserves. Reservoir
engineering studies prepared on behalf of the Company indicate significant
additions to its proved reserves in this field can continue to be made through
additional EOR and development projects. The Company has identified a
substantial number of locations that could be drilled in the field, depending in
part on future prices and economic conditions. The Company is pursuing
electrical cogeneration opportunities which could lower Midway-Sunset operating
costs.
 
    SOUTH BELRIDGE.  The South Belridge field is located approximately 15 miles
north of the Midway-Sunset field. The Company operates three leases in the field
which produce heavy oil from the shallow Tulare sands and lighter low viscosity
oil from the deeper Diatomite reservoirs. Steamflood operations in the lower
Tulare sands are in progress on one of these leases and plans call for flooding
the remaining Tulare sands on this lease and all Tulare sands on another lease
in the coming years. Waterflood operations in the Diatomite reservoir have been
initiated on two leases and the Company expects to expand these operations to
include the rest of the developed area.
 
    COALINGA.  The Coalinga field is located 55 miles southwest of Fresno,
California. Successful steamfloods and a pilot steamflood project have been
conducted in the Lower Temblor Sands on three of the six leases in which the
Company owns interests in the field. During the next several years, the Company
plans to expand the pilot steamflood project in the lower sands to cover the
remaining producing area and expand steam floods on the Upper Temblor Sands on
all leases after depletion of the lower zones. Most of the facilities required
for these projects are already in place as a result of the prior steamfloods.
 
    KERN RIVER.  The Kern River field is located near Bakersfield, California.
The Lower Kern River Series sands have been successfully steamflooded on three
of the leases in which the Company owns an interest. Over the next several years
steamflood operations will be sequentially redeployed in the upper sands of the
Kern River Series. Eventually the Company plans to flood all sands on its
remaining lease in several stages. The Company has installed and operates a
large steam generation plant on these properties.
 
    PERMIAN BASIN
 
    WASSON.  The Company's interests in the field principally consist of royalty
and working interests in three units which are presently under CO2 flood. Most
of the expenditures for plant, facilities, wells and equipment necessary for
such tertiary recovery projects have been made. In addition, while expenditures
relating to the purchase of CO2 for the Wasson field are expected to continue,
CO2 can be recycled and, therefore, such expenditures should decline in the
future.
 
    During 1993 the Wasson field accounted for approximately 9% of the Company's
domestic crude oil and liquids production and at December 31, 1993 the field
accounted for approximately 8% of the Company's domestic proved crude oil and
liquids reserves. Since initiation of CO2 flooding operations in 1984, the
field's previous production decline has been reversed. Reservoir engineering
studies
 
                                       6
 
<PAGE>
prepared on behalf of the Company indicate significant additions to proved
reserves can be made through additional EOR and development projects.
 
    REEVES.  The Company owns a 72% net interest in the Reeves field, seven
miles east of the large Wasson field in west Texas. The field has been under
waterflood since 1965. During 1993 six wells were drilled and 16 wells were
worked over as part of a program to delineate the extended productive limits of
the field, to evaluate the potential for infill drilling and to enhance current
waterflood operations. Based on the successes of the prior year's program, the
Company plans to initiate an infill drilling and workover program in this field
in the near future.
 
    NEW MEXICO.  During 1993 the Company increased its activity in the light-oil
Delaware play in Lea and Eddy Counties of southeast New Mexico. A total of 51
gross (18.1 net) development wells were completed in 1993 with a 100% success
rate and in December 1993 such wells produced approximately 1,400 barrels of oil
and 3.1 MMcf of natural gas per day. Net production from this area in December
1993 totaled approximately 1,500 barrels of oil and 4.0 MMcf of natural gas per
day. The Company plans to drill additional development wells in 1994.
 
    Also in southeastern New Mexico, the Company participated in five gross (2.8
net) wells in 1993 in the light oil and gas Cisco-Canyon project. Four wells
were completed as producers from the Cisco-Canyon zone by year end and a fifth
continued production testing. The Company plans to continue delineation of this
play which contains some 75 identified potential development locations.
 
    OFFSHORE GULF OF MEXICO
 
    At December 31, 1993, offshore Gulf of Mexico properties accounted for 39%
of the Company's proved natural gas reserves and during 1993 these properties
accounted for approximately 56% of the Company's natural gas production.
 
    In the Gulf Division, several new fields or field additions were placed on
production during 1993. Net production from these fields at year end averaged
approximately 29.0 MMcf of gas per day. Further development in these fields are
either planned or under study for 1994 and 1995. The Company's activities in the
offshore Gulf of Mexico are conducted in the shallow water (less than 300 feet),
where the costs of drilling, completion and production are not as uncertain as
are the costs in the Flextrend and Deepwater areas of the Gulf of Mexico. During
1993, the Company participated in the drilling of four gross (1.3 net)
exploratory wells and one gross (0.3 net) well was drilling at year end (which
well resulted in a discovery and a multiwell development program is expected to
commence in 1994). For a description of the Company's leasehold position in the
offshore Gulf of Mexico, see '-- Domestic Exploration Activities.'
 
DOMESTIC EXPLORATION ACTIVITIES
 
    The Company's domestic exploration focus continues to be in the Permian
Basin and the offshore Gulf of Mexico. Overall the Company participated in 22
gross (9.0 net) exploratory wells in 1993. A total of ten gross (3.6 net) were
completed as producers for a 40% net well success. At year end there were nine
gross (4.3 net) wells in some stage of drilling or completion.
 
    As of December 31, 1993, the Company held approximately 0.3 million net
undeveloped leasehold acres in 14 states and offshore areas, excluding
approximately 0.5 million net undeveloped leasehold acres committed to Bridge
under the terms of a Purchase and Sales Agreement signed in December 1993. The
primary terms of lease expire with respect to 24% of such acreage in 1994, 25%
in 1995, 15% in 1996, 10% in 1997 and the remainder thereafter. In addition, the
Company owns approximately 0.5 million net acres of undeveloped fee minerals in
Louisiana, Texas and California.
 
    The Company also controls the oil and gas rights on approximately 8.1
million net undeveloped acres in the western United States through direct
ownership and pursuant to lease option agreements from Santa Fe Pacific Railroad
Company and other former affiliates. These lands are located in high risk
exploration areas. Due to this risk, the Company has historically negotiated
with third parties to explore this acreage with the Company to receive a royalty
or carried interest in the exploration
 
                                       7
 
<PAGE>
phase. An agreement relating to substantially all of these oil and gas rights
has been entered into with Bridge. This agreement is intended to provide
incentive to Bridge to accelerate exploration activities on lands subject to
these rights. The Company will receive a small revenue interest in the event
such activities are successful.
 
    Set forth below is a brief discussion of some of the Company's principal
exploration programs.
 
    PERMIAN BASIN.  This area continues to be one of the Company's most active
and successful exploration areas. During 1993, the Company participated in 18
gross (7.7 net) exploratory wells. Eight gross (3.3 net) of these were completed
in 1993 as oil or gas discoveries. Additionally, eight gross (4.0 net) were in
some phase of drilling or completing at year end.
 
    Drilling objectives for the Company's exploratory program target oil and gas
zones at depths of between 2,500 to 15,000 feet. The shallower targets such as
the Delaware, and Cisco-Canyon formations are providing successful results. The
Delaware program in southeast New Mexico was the subject of seven gross (3.7
net) exploratory and 51 gross (18.1 net) development wells completed in 1993. A
success rate of 58% of the net exploratory wells and 100% of the net development
wells was achieved in this increasingly active light oil play. Currently the
Company has identified in excess of 150 development well locations and has 20
exploratory prospects in inventory to be drilled over the next several years.
 
    In the west Texas Permian Basin, the Company completed the shooting of 3-D
seismic over its 250 square mile block near Midland last fall. The joint venture
block contains over 100,000 net acres of lands owned or controlled by the
Company and its partners. Almost all of the Company's 25% interest in the 3-D
seismic was paid by a promoted partner. Drilling began in December 1993 on two
prospects identified in this program. Additional drilling is planned on a
variety of other prospects in 1994 at depths of 10,000 to 12,000 feet.
 
    OFFSHORE GULF OF MEXICO.  The Company participated in four gross (1.3 net)
exploratory wells in the offshore in 1993 and one gross (0.3 net) was drilling
at year end. One gross (0.3 net) well resulted in a discovery on which a
multiwell development program will commence in the second quarter of 1994.
 
    The Company acquired 3-D seismic coverage over 12 blocks during 1993 adding
to its extensive Gulf of Mexico seismic database which includes 3-D coverage on
57 blocks. Currently the Company has 35 exploratory prospects in inventory and
some 30 development locations identified a portion of which are exploratory
planned to be drilled in 1994.
 
    At year end the Company owned 179 blocks of acreage in the Gulf of Mexico
consisting of approximately 299,800 gross (147,400 net) undeveloped acres and
257,900 gross (79,000 net) developed acres.
 
INTERNATIONAL DEVELOPMENT ACTIVITIES
 
    INDONESIA.  The Company, through a wholly owned subsidiary, is engaged in
the production of crude oil in Indonesia through a joint venture (the 'Salawati
Basin Joint Venture') formed in 1970 to explore for and develop hydrocarbon
reserves in the Salawati Basin area of Irian Jaya. At December 31, 1993, the
Company held a 33 1/3% participation interest in, and acts as operator for, the
Salawati Basin Joint Venture. The Salawati Basin Joint Venture operates under a
production sharing contract (the 'PSC') with the Indonesia state oil agency
('Pertamina'), which had an initial term of 30 years and expires in the year
2000. The Company is currently negotiating with such state oil agency to extend
the contract for an additional 20 years. As of December 31, 1993, the contract
covered an area of approximately 235,000 acres. Production occurs from seven oil
and three gas condensate fields.
 
    The PSC entitles the Salawati Basin Joint Venture to recover all of its
expenditures related to the operation (the 'cost recovery amount') before any
additional production is shared with the Indonesian state oil agency, which
recovery is effected by allocating to the Salawati Basin Joint Venture a portion
of the crude oil production sufficient, at the Indonesia government official
crude oil price ('ICP'), to offset the cost recovery amount. The balance of
production after the cost recovery
 
                                       8
 
<PAGE>
amount is divided between the parties, with approximately 66% allocated to
Pertamina and 34% allocated to the Salawati Basin Joint Venture. However, 25% of
the 34% pre-tax portion (8.5% of total production) must be sold into the
Indonesian domestic market for $0.20 per barrel. The entire entitlement of the
Salawati Basin Joint Venture under the PSC, including the domestic market
obligation, averaged approximately 10.1 MBbls per day (approximately 3.4 MBbls
per day net to the Company) for the year ended December 31, 1993. The Salawati
Basin Joint Venture is required to pay Indonesian income taxes at the rate of
56%.
 
    The Company, through another subsidiary, has also entered into a joint
venture with Pertamina to explore the Salawati Island Block of Irian Jaya. The
effective date of this joint venture is April 23, 1990 with a term of 30 years.
At December 31, 1993, the Company held a 16 2/3% participation interest in the
block which covers 1.09 million acres. The Company and Pertamina (with its 50%
interest) jointly operate the contract area. In 1991, a successful exploratory
well tested at a combined rate of 3,568 barrels of oil per day and was followed
by two successful delineation wells. Pertamina declared the field commercial in
January 1993 and designated it as the Matoa Field. Sales of production began in
January of 1993. Development activities through 1993 have the Matoa field
producing approximately 5,600 barrels of oil per day from eight wells as of
December 31, 1993.
 
    Under the terms of the PSC, the joint venture participants are allowed to
recover the cost recovery amount, after an initial 20% portion (2.9% to the
joint venture participants and 17.1% to Pertamina) has been deducted, by
allocating to the joint venture participants a portion of the crude oil
production ('cost oil') sufficient to offset the cost recovery amount. All
unrecovered costs in any calendar year can be carried forward to future years.
The balance of production after allocation of cost oil is allocated
approximately 85.5% to Pertamina and 14.5% to the other Salawati Island Joint
Venture participants. However, 7.25% of the gross production allocated to the
joint venture participants must be sold into the Indonesian domestic market for
10% of ICP.
 
    ARGENTINA.  In 1991, the Company, through a wholly owned subsidiary,
acquired an 18% non-operated working interest (15.84% net interest) in the El
Tordillo field in Chubut Province, Argentina. At that time, the field was
producing approximately 10,500 barrels of oil per day. The Company has agreed to
spend approximately $16.7 million net during the period from July 1, 1992 to
July 1, 1996 on development and maintenance of the field which began with an
extensive workover and recompletion program. As of December 31, 1993 the El
Tordillo owners have completed 163 such workovers and drilled three new wells.
During that time production increased to approximately 16,000 barrels of oil per
day. The Company expects this program to continue through 1994 and anticipates
an expansion of the existing waterflood facilities.
 
    Under the terms of the contract with the Argentine national oil company, the
joint venture group is allowed to sell crude oil produced from this field into
the open market. There is a 12% royalty on gross production and the joint
venture is taxed at a 30% rate after deductions for capitalized costs and
expenses.
 
    In April 1993, the Company's subsidiary completed the Sierra Chata X-1 as a
successful exploratory test in Chihuidos Block, Neuquen Province, Argentina. The
well produced at a combined rate of 22.2 million cubic feet per day and 109
barrels of condensate per day. Carbon dioxide content of the natural gas was 6%.
Five successful delineation wells were drilled in 1993. Producing rates on these
wells varied from 3.2 to 27.6 million cubic feet per day. Engineering and
geological studies are presently being undertaken to develop the field through
additional drilling, with 4.0 gross (1.0 net) additional wells currently planned
for 1994. In addition, the Company and its partners intend to build a gas
processing facility and a 40-mile gathering pipeline during 1994 that will
transport production from the field and interconnect with a main transmission
line owned by a third party that transports gas to Buenos Aires and other major
markets. Construction of the gas processing facility and the pipeline and the
drilling of the development wells are estimated to cost an aggregate of $76.0
million gross ($17.2 million net to the Company's interest). The Company expects
that sales of production from the Sierra Chata discovery will commence in 1995.

INTERNATIONAL EXPLORATION ACTIVITIES
 
    In 1993, the Company had its most active year ever in the international
arena. The Company participated in six gross (1.8 net) exploratory wells of
which two gross (0.5 net) were completed as natural gas wells. Additionally,
four gross (1.2 net) wells were either drilling or completing at year end.
 
    The Company made one exploration discovery in 1993. The Sierra Chata natural
gas discovery in the Neuquen Basin of Argentina is being developed from
sandstone reservoirs at 6,000 feet. The Company has a 22.5% working interest
(20% net revenue interest) and is operator of this field. To date a total of
six gross (1.3 net) wells have been drilled with no dry holes. Combined gross
flow rates from these six wells are in excess of 100 million cubic feet of
gas and 500 barrels of condensate per day. Additional development drilling
will continue during 1994 to increase production capacity and further define
the limits of the field. See '-- International Development Activities.'
 
    The Company plans to drill eight gross (2.8 net) wells in 1994 in addition
to the four gross (1.2 net) wells which carried over from 1993 in either a
drilling or completing status. The 1994 drilling and exploratory activity will
be centered principally in Indonesia and South America. Of the total wells to be
completed in 1994, four gross (1.2 net) are in Indonesia, four gross (1.3 net)
are in Argentina and Bolivia, one gross (0.2 net) is in Papua New Guinea, two
gross (1.0 net) are in Canada and one gross (0.3 net) is in Gabon (West Africa).
 
    The Company holds exploration contracts totaling 3.5 million net acres in
eight foreign countries. The majority of acreage is in Indonesia (1.1 million
net acres) and South America (1.2 net million acres) with the balance in Canada,
Morocco, Myanmar, Papua New Guinea and Gabon.

CURRENT MARKETS FOR OIL AND GAS
 
    The revenues generated by the Company's operations are highly dependent upon
the prices of, and demand for, oil and gas. For the last several years, prices
of these products have reflected a worldwide surplus of supply over demand. The
price received by the Company for its crude oil and natural gas depends upon
numerous factors beyond the Company's control, including economic conditions in
the United States and elsewhere and the world political situation as it affects
OPEC, the Middle East (including the current embargo of Iraqi crude oil from
worldwide markets) and other producing countries, the actions of OPEC and
governmental regulation. The fluctuation in world oil prices continues to
reflect market uncertainty regarding OPEC's ability to control member country
production and underlying concern about the balance of world demand for and
supply of oil and gas. Decreases in the prices of oil and gas have had, and
could have in the future, an adverse effect on the Company's development and
exploration programs, proved reserves, revenues, profitability, cash flow and
dividend levels. See Item 7. 'Management's Discussion and Analysis of Financial
Condition and Results of Operations -- General.'
 
    The Company believes the market for heavy crude oil produced in California
differs substantially from the remainder of the domestic crude oil market. It is
necessary to heat or dilute heavy oil to make it flow, which increases
transportation and handling costs, and it is also more costly to refine. As a
result, the price paid for heavy crude oil is generally lower than the price
paid for light crudes. In addition, there is currently an oversupply of crude
oil in the California market that has had an adverse effect on the prices for
crude oil in that market. Although no assurance can be given, the Company
believes that such oversupply will not continue for the long term due to the
availability of crude oil pipelines to transport excess crude oils, including
blended oils, to markets in the midwest and west Texas, and due to the decline
of crude oil produced from the North Slope of Alaska.
 
    From time to time the Company has hedged a portion of its oil and natural
gas production to manage its exposure to volatility in prices of oil and natural
gas. The Company used several instruments whereby monthly settlements were based
on the difference between the price, or a range of prices, specified in the
instruments and the monthly average of the daily settlement prices of certain
West Texas Intermediate ('WTI') crude oil futures contracts or of certain
natural gas futures contracts quoted on the New York Mercantile Exchange. In
instances where the actual average of the daily settlement price was less than
the price specified in the contract, the Company received a settlement based on
the difference; in instances where the actual average of the daily settlement
price was higher than the specified price, the Company paid an amount based on
the difference. The instruments utilized by the Company differed from futures
contracts in that there was no contractual obligation which required or allowed
for the future delivery of the product. Settlements were included in revenues in
the period in which the oil and natural gas were sold.
 
    In 1990, oil hedges resulted in a $10.7 million reduction in oil revenues
and in 1991 and 1992 oil hedges resulted in an increase in oil revenues of $41.7
million and $9.7 million, respectively. The Company has had no oil hedging
contracts subsequent to 1992. In 1992 and 1993, natural gas hedges resulted in a
reduction in natural gas revenues of $0.5 million and $8.2 million,
respectively. The Company currently has six open natural gas hedging contracts
for approximately 24.6 MMcf per day during the seven month period beginning
March 1994. The 'approximate break-even price' (the average of the monthly
settlement prices of the applicable futures contracts which would result in no
settlement being due to or from the Company) with respect to such contracts is
approximately $1.88 per Mcf. In addition, a certain party holds an option on
a contract covering approximately 4.7 MMcf per day during the five month period
beginning May 1994 at an approximate break even price of $1.92 per Mcf. The
Company has no other outstanding natural gas hedging instruments.
 
    During 1993, affiliates of Shell Oil Company and Celeron Corporation
accounted for approximately 23% and 15% respectively, of the Company's domestic
crude oil and liquids and natural gas revenues. No other individual customer
accounted for more than 10% of such revenues during 1993. Substantially all of
the Company's oil and natural gas production is currently sold at market-
 
                                       13
 
<PAGE>
responsive prices that approximate spot prices. Availability of a ready market
for the Company's oil and gas production depends on numerous factors, including
the level of consumer demand, the extent of worldwide oil production, the cost
and availability of alternative fuels, the cost of and proximity of pipelines
and other transportation facilities, regulation by state and federal authorities
and the cost of complying with applicable environmental regulations.
 
    In December 1993, the Company signed a seven-year gas sales contract with
Hadson pursuant to the terms of which Hadson will market substantially all of
the Company's domestic natural gas production. Pursuant to such gas contract,
Santa Fe dedicated to Hadson all of its domestic natural gas production from
specified existing wells, which consist of essentially all of the Company's
domestic natural gas production, except to the extent such production was
dedicated under pre-existing contracts. Upon the expiration of any such
pre-existing contracts, that production shall also be dedicated to the Company.
 
    In addition to production from existing wells, such gas contract provides
for the dedication by the Company of gas production from certain domestic
development wells and exploration wells to the extent that the Company accepts
proposals from Hadson to gather and market production from such exploration
wells. Production from gas wells acquired by the Company pursuant to an
acquisition of producing oil and gas properties will not be dedicated under the
gas contract but may be dedicated by the mutual agreement of the Company and
Hadson.
 
    Pursuant to the gas contract, Hadson will be required to pay the Company for
all production delivered at a price for such gas equal to stipulated published
monthly index prices. Hadson is obligated to use its best efforts to receive gas
from the Company at delivery points so as to maximize the net price received by
the Company for such production. Payment for purchases by Hadson are to be made
in immediately available funds no later than the last working day of the month
following the month of production.
 
SANTA FE ENERGY TRUST
 
    In November 1992, 5,725,000 Depositary Units ('Depositary Units'), each
consisting of beneficial ownership of one unit of undivided interest in Santa Fe
Energy Trust (the 'Trust') and a $20 face amount beneficial ownership interest
in a $1,000 face amount zero coupon United States Treasury obligation maturing
on February 15, 2008, were sold in a public offering. The assets of the Trust
consist of certain oil and gas properties conveyed by the Company. A total of
$114.5 million was received from public investors, of which $38.7 million was
used to purchase the Treasury obligations and $5.7 million was used to pay
underwriting commissions and discounts. The Company received the remaining $70.1
million and retained 575,000 Depositary Units. A portion of the proceeds
received by the Company was used to retire $30.0 million of the debt incurred in
connection with the Merger and the remainder was used for general corporate
purposes. In the first quarter of 1994, the Company sold the remaining 575,000
Depositary Units it held for $11.3 million.
 
    The properties conveyed to the Trust consisted of two term royalty interests
in two production units in the Wasson field in west Texas and a net profits
royalty interest in certain royalty and working interests in a diversified
portfolio of properties located in twelve states. At December 31, 1993, 5.2
MMBOE of the Company's estimated proved reserves were subject to such net
profits interest. The reserve estimates included herein reflect the conveyance
of the Wasson term royalties to the Trust.
 
    For any calendar quarter ending on or prior to December 31, 2002, the Trust
will receive additional royalty payments to the extent that such payments are
required to provide distributions of $0.40 per Depositary Unit per quarter. Such
additional royalty payments, if needed, will come from the Company's remaining
royalty interest in one of the production units in the Wasson field described
above, and are non-recourse to the Company. If such additional payments are
made, certain proceeds otherwise payable to the Trust in subsequent quarters may
be reduced to recoup the amount of such additional payments. The aggregate
amount of the additional royalty payments (net
 
                                       14
 
<PAGE>
of any amounts recouped) will be limited to $20.0 million on a revolving basis.
The Company was required to make an additional royalty payment of $362,000 with
respect to the distribution made by the Trust for operations during the quarter
ended December 31, 1993. Based upon current prices, the Company believes that a
support payment will be required for the quarter ending March 31, 1994, the
amount of which has not been determined.
 
OTHER BUSINESS MATTERS
 
  COMPETITION
 
    The Company faces competition in all aspects of its business, including, but
not limited to, acquiring reserves, leases, licenses and concessions; obtaining
goods, services and labor needed to conduct its operations and manage the
Company; and marketing its oil and gas. The Company's competitors include
multinational energy companies, government-owned oil and gas companies,
other independent producers and individual producers and operators. The
Company believes that its competitive position is affected by price, its
geological and geophysical capabilities and ready access to markets
for production. Many competitors have greater financial and other
resources than the Company, more favorable exploration prospects and ready
access to move favorable markets for their production. The Company believes that
the well-defined nature of the reservoirs in its long-lived oil fields, its
expertise in EOR methods in these fields, its active development and
exploration position and its experienced management may give it a competitive
advantage over some other producers.
 
  REGULATION OF CRUDE OIL AND NATURAL GAS
 
    The petroleum industry is subject to various types of regulation throughout
the world, including regulation in the United States by state and federal
agencies. Domestic legislation affecting the oil and gas industry is under
constant review for amendment or expansion, frequently increasing the regulatory
burden. Also, numerous departments and agencies, both federal and state, are
authorized by statute to issue and have issued rules and regulations binding on
the oil and gas industry and its individual members, compliance with which is
often difficult and costly and which may carry substantial penalties for
non-compliance. Although the regulatory burden on the oil and gas industry
increases the cost of doing business and, consequently, affects profitability,
generally these burdens do not appear to affect the Company any differently or
to any greater or lesser extent than other companies in the industry with
similar types and quantities of production. While the Company is a party to
several regulatory proceedings before governmental agencies arising in the
ordinary course of business, management does not believe that the outcome of
such proceedings will have a material adverse affect on the operations or
financial condition of the Company. Set forth below is a general description of
certain state and federal regulations which have an effect on the Company's
operations.
 
    STATE REGULATION.  State statutes and regulations require permits for
drilling operations, drilling bonds and reports concerning operations. Most
states in which the Company operates also have statutes and regulations
governing the conservation of oil and gas and the prevention of waste, including
the unitization or pooling of oil and gas properties and rates of production
from oil and gas wells. Rates of production may be regulated through the
establishment of maximum daily production allowables on a market demand or
conservation basis or both.
 
    FEDERAL REGULATION.  A portion of the Company's oil and gas leases are
granted by the federal government and administered by the Bureau of Land
Management ('BLM') and the Minerals Management Service ('MMS'), both of which
are federal agencies. Such leases are issued through competitive bidding,
contain relatively standardized terms and require compliance with detailed BLM
and MMS regulations and orders (which are subject to change by the BLM and the
MMS). For offshore operations, lessees must obtain MMS approval for exploration
plans and development and production plans prior to the commencement of such
operations. In addition to permits required from other agencies (such as the
Coast Guard, Army Corps of Engineers and Environmental
 
                                       15
 
<PAGE>
Protection Agency), lessees must obtain a permit from the BLM or the MMS prior
to the commencement of drilling.
 
    The interstate transportation of natural gas is regulated by the Federal
Energy Regulatory Commission ('FERC') under the Natural Gas Act of 1938 and, to
a lesser extent, the Natural Gas Policy Act of 1978 (collectively, the 'Acts').
Numerous questions have been raised concerning the interpretation and
implementation of several significant provisions of the Acts, as well as the
regulations and policies promulgated by FERC thereunder. A number of lawsuits
and administrative proceedings have been instituted which challenge the validity
of regulations implementing the Acts. In addition, as described below, FERC
currently has under consideration various policies and proposals which will
affect the marketing of gas under new and existing contracts.
 
    Since 1991, FERC's regulatory efforts have centered largely around its
generic rulemaking proceedings, Order No. 636. Through Order No. 636 and
successor orders, FERC has undertaken to restructure the interstate pipeline
industry with the goal of providing enhanced access to, and competition among,
alternative gas suppliers. By requiring interstate pipelines to 'unbundle' their
sales services and to provide its customers with direct access to any upstream
pipeline capacity held by pipelines, Order No. 636 has enabled pipeline
customers to choose the levels of transportation and storage service they
require, as well as to purchase gas directly from third-party merchants other
than the pipelines.
 
    Although the implementation of Order No. 636 on individual interstate
pipelines is nearing completion, this process is not yet final. Moreover, nearly
all of these individual restructuring proceedings, as well as Order No. 636
itself and the regulations promulgated thereunder, are subject to pending
appellate review and could possibly be substantially modified by the courts.
Thus, while Order No. 636, if ultimately implemented without substantial change,
should generally facilitate the transportation of gas and the direct access to
end-user markets, the precise impact of these regulations on marketing
production cannot be predicted at this time.
 
    Beyond Order No. 636, FERC is now considering a number of other important
policies, all of which could significantly affect the marketing of gas. Some of
the more notable of these regulatory initiatives include FERC's rulemakings on
gathering and production-area rate design, regulation of pipeline marketing
affiliates under Order No. 497, and standards for pipeline electronic bulletin
boards and electronic data exchange.
 
    The U.S. Congress has historically been active in the area of oil and
natural gas regulation. Although no prediction can be made concerning future
regulation or legislation which may affect the competitive status of the
Company, or affect the prices at which it may sell its oil and gas, any
regulation or legislation that, directly or indirectly, lowers price levels for
oil and gas sold or increases the costs of production could have an adverse
effect on the Company's operations.
 
  ENVIRONMENTAL REGULATION
 
    Various federal, state and local laws and regulations covering the discharge
of materials into the environment, or otherwise relating to the protection of
the environment, may affect the Company's operations and costs. In particular,
the Company's oil and gas exploration, development, production and EOR
operations, its activities in connection with storage and transportation of
liquid hydrocarbons and its use of facilities for treating, processing,
recovering or otherwise handling hydrocarbons and wastes therefrom are subject
to stringent environmental regulation by governmental authorities. Such
regulation has increased the cost of planning, designing, drilling, installing,
operating and abandoning the Company's oil and gas wells and other facilities.
The Company has expended significant resources, both financial and managerial,
to comply with environmental regulations and permitting requirements and
anticipates that it will continue to do so in the future in order to comply with
stricter industry and regulatory safety standards such as those described below.
Although the Company believes that its operations and facilities are in general
compliance with applicable environmental regulations, risks of substantial costs
and liabilities are inherent in oil and gas
 
                                       16
 
<PAGE>
operations and there can be no assurance that significant costs and liabilities
will not be incurred in the future. Moreover, it is possible that other
developments, such as increasingly strict environmental laws, regulations and
enforcement policies thereunder, and claims for damages to property, employees,
other persons and the environment resulting from the Company's operations, could
result in substantial costs and liabilities in the future. Although the
resulting costs cannot be accurately estimated at this time, these requirements
and risks typically apply to companies with types and quantities of production
similar to those of the Company and to the oil and gas industry in general.
 
    OFFSHORE PRODUCTION.  Offshore oil and gas operations are subject to
regulations of the United States Department of the Interior, the Department of
Transportation, the United States Environmental Protection Agency ('EPA') and
certain state agencies. In particular, the Federal Water Pollution Act of 1972,
as amended ('FWPCA'), imposes strict controls on the discharge of oil and its
derivatives into navigable waters. The FWPCA provides for civil and criminal
penalties for any discharges of petroleum in reportable quantities and, along
with the Oil Pollution Act of 1990 and similar state laws, imposes substantial
liability for the costs of oil removal, remediation and damages.
 
    SOLID AND HAZARDOUS WASTE.  The Company currently owns or leases, and has in
the past owned or leased, numerous properties that have been used for production
of oil and gas for many years. Although the Company has utilized operating and
disposal practices that were standard in the industry at the time, hydrocarbons
or other solid wastes may have been disposed or released on or under the
properties owned or leased by the Company. State and federal laws applicable to
oil and gas wastes and properties have gradually become more strict. Under these
new laws, the Company has been, and in the future could be, required to remove
or remediate previously disposed wastes or property contamination (including
groundwater contamination) or to perform remedial plugging operations to prevent
future contamination.
 
    The Company generates hazardous and nonhazardous wastes that are subject to
the federal Resource Conservation and Recovery Act and comparable state
statutes. The EPA has limited the disposal options for certain hazardous wastes
and is considering the adoption of stricter disposal standards for nonhazardous
wastes. Furthermore, it is anticipated that additional wastes (which could
include certain wastes generated by the Company's oil and gas operations) will
in the future be designated as 'hazardous wastes,' which are subject to more
rigorous and costly disposal requirements. In response to the changing
regulatory environment, the Company has made certain changes in its operations
and disposal practices. For example, the Company has commenced remediation of
sites or replacement of facilities where its wastes have previously been
disposed.
 
    SUPERFUND.  The Comprehensive Environmental Response, Compensation and
Liability Act ('CERCLA'), also known as the 'superfund' law, imposes liability,
without regard to fault or the legality of the original conduct, on certain
classes of persons that contributed to the release of a 'hazardous substance'
into the environment. These persons include the owner or operator of a site and
companies that disposed or arranged for the disposal of the hazardous substance
found at a site. CERCLA also authorizes the EPA and, in some cases, third
parties to take actions in responses to threats to the public health or the
environment and to seek to recover from the responsible classes of persons the
costs they incur. In the course of its operations, the Company has generated and
will generate wastes that may fall within CERCLA's definition of 'hazardous
substances.' The Company may be responsible under CERCLA for all or part of the
costs to clean up sites at which such wastes have been disposed.
 
    The Company has been identified as one of over 250 potentially responsible
parties ('PRPs') at a superfund site in Los Angeles County, California. The site
was operated by a third party as a waste disposal facility from 1948 until 1983.
The EPA is requiring the PRPs to undertake remediation of the site in several
phases, which include site monitoring and leachate control, gas control and
final remediation. In 1989 the EPA and a group of the PRPs entered into a
consent decree covering the site monitoring and leachate control phase of
remediation. The Company is a member of the group that is
 
                                       17
 
<PAGE>
responsible for carrying out this first phase of work, which is expected to be
completed in five to eight years. The maximum liability of the group, which is
joint and several for each member of the group, for the first phase is $37.0
million, of which the Company's share is expected to be approximately $2.4
million ($1.3 million after recoveries from working interest participants in the
unit at which the wastes were generated) payable over the period that the phase
one work is performed. The EPA and a group of PRPs of which the Company is a
member have also entered into a subsequent consent decree (which has not yet
been finally entered by the court) with respect to the second phase of work (gas
control). The liability of this group has not been capped, but is estimated to
be $130 million. The Company's share of costs for this phase, however, is
expected to be approximately of the same magnitude as that of the first phase
because more parties are involved in the settlement. The Company has provided
for costs with respect to the first two phases, but it cannot currently estimate
the cost of any subsequent phases of work which may be required by the EPA.
 
    In 1989, Adobe received requests from the EPA for information pursuant to
Section 104(e) of CERCLA with respect to the D. L. Mud and Gulf Coast Vacuum
Services superfund sites located in Abbeville, Louisiana. The EPA has issued its
record of decision at the Gulf Coast Site and on February 9, 1993 the EPA issued
to all PRPs at the site a settlement order pursuant to Section 122 of CERCLA.
Earlier, an emergency order pursuant to Section 106 of CERCLA was issued on
December 11, 1992, for purposes of containment due to the Louisiana rainy
season. On December 15, 1993 the Company entered into a cost-sharing agreement
with other PRPs to participate in the final remediation of the Gulf Coast site
which is presently estimated to cost $15.0 million. The Company's share of the
remediation is approximately $600,000 and reflects its proportionate share of
the orphans' shares of this site. With respect to the D.L. Mud site, a former
site owner has already conducted remedial activities at the site under a state
agency agreement. To date the Company has not been requested to share in the
remediation costs. The extent, if any, of any further necessary remedial
activity at and the prospective PRPs and the Company's financial obligations
for, the D. L. Mud Site has not been finally determined.
 
    The Company has received a request for information from the EPA regarding
the Lee Acres Landfill CERCLA site in New Mexico. The Company advised the EPA
that it was not able to locate any information indicating that it had used that
facility. The Company is investigating its potential connection, if any, to this
facility and is not able to estimate its share of costs, if any, for the site at
this time.
 
    AIR EMISSIONS.  The operations of the Company, including most of its
operations in the San Joaquin Valley, are subject to local, state and federal
regulations for the control of emissions from sources of air pollution. Legal
and regulatory requirements in this area are increasing, and there can be no
assurance that significant costs and liabilities will not be incurred in the
future as a result of new regulatory developments. In particular, the 1990 Clean
Air Act amendments will impose additional requirements that may affect the
Company's operations, including permitting of existing sources and control of
hazardous air pollutants. However, it is impossible to predict accurately the
effects, if any, of the Clean Air Act Amendments on the Company at this time.
The Company has been and may in the future be subject to administrative
enforcement actions for failure to comply strictly with air regulations or
permits. These administrative actions are generally resolved by payment of a
monetary penalty and correction of any identified deficiencies. Alternatively,
regulatory agencies may require the Company to forego construction or operation
of certain air emission sources.
 
    OTHER.  The Company is subject to the requirements of the federal
Occupational Safety and Health Act ('OSHA') and comparable state statutes. The
OSHA hazard communication standard, the EPA community right-to-know regulations
under Title III of the federal Superfund Amendment and Reauthorization Act and
similar state statutes (such as California Proposition 65) require the Company
to organize information about hazardous materials used or produced in its
operations. Certain of this information must be provided to employees, state and
local governmental authorities
 
                                       18
 
<PAGE>
and local citizens. The Company's facilities in California are also subject to
California Proposition 65, which was adopted in 1986 to address discharges and
releases of, or exposures to, toxic chemicals in the environment. Proposition 65
makes it illegal to knowingly discharge a listed chemical if the chemical will
pass (or probably will pass) into any source of drinking water. It also
prohibits companies from knowingly and intentionally exposing any individual to
such chemicals through ingestion, inhalation or other exposure pathways without
first giving a clear and reasonable warning.
 
    Although generally less stringent, the Company's foreign operations are
subject to similar foreign laws respecting environmental and worker safety
matters.
 
  INSURANCE COVERAGE MAINTAINED WITH RESPECT TO OPERATIONS
 
    The Company maintains insurance policies covering its operations in amounts
and areas of coverage normal for a company of its size in the oil and gas
exploration and production industry. These coverages include, but are not
limited to, workers' compensation, employers' liability, automotive liability
and general liability. In addition, an umbrella liability and operator's extra
expense policies are maintained. All such insurance is subject to normal
deductible levels. The Company does not insure against all risks associated with
its business either because insurance is not available or because it has elected
not to insure due to prohibitive premium costs.
 
  EMPLOYEES
 
    As of December 31, 1993, the Company had approximately 777 employees, 210 of
whom were covered by a collective bargaining agreement which expires on January
31, 1996. The Company believes that its relations with its employees are
satisfactory.
 
ITEM 3.  LEGAL PROCEEDINGS
 
    The Company, its subsidiaries and other related companies are named
defendants in several lawsuits and named parties in certain governmental
proceedings arising in the ordinary course of business. For a description of
certain proceedings in which the Company is involved, see Items 1 and 2 '
Business and Properties -- Other Business Matters -- Environmental Regulation'
and Notes 12 and 13 to the Consolidated Financial Statements. While the outcome
of lawsuits or other proceedings against the Company cannot be predicted with
certainty, management does not expect these matters to have a material adverse
effect on the financial position or results of operations of the Company.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS
 
    For the year ended December 31, 1993 the Company reported a loss to common
shares of $84.1 million, or $0.94 per share. The loss for the year includes a
$99.3 million charge for the impairment of oil and gas properties (see
' -- Results of Operations') and a $38.6 million restructuring charge (see Items
1 and 2. 'Business and Properties -- Corporate Restructuring Program'). The
restructuring charge is comprised of losses on property dispositions of $27.8
million, long-term debt repayment penalties of $8.6 million and accruals for
certain personnel benefits and related costs of $2.2 million. At December 31,
1993 the Company's long-term debt totalled $449.7 million, a portion of
which the Company intends to refinance to reduce required debt amortization in
the near-term and provide additional financial flexibility in the current low
oil price environment.
 
GENERAL
 
    As an independent oil and gas producer, the Company's results of operations
are dependent upon the difference between the prices received for oil and gas
and the costs of finding and producing such resources. A substantial portion of
the Company's crude oil production is from long-lived fields where EOR methods
are being utilized. The market price of the heavy (i.e., low gravity, high
viscosity) and sour (i.e., high sulfur content) crude oils produced in these
fields is lower than sweeter, light (i.e., low sulfur and low viscosity) crude
oils, reflecting higher transportation and refining costs. The lower price
received for the Company's domestic heavy and sour crude oil is reflected in the
average sales price of the Company's domestic crude oil and liquids (excluding
the effect of hedging transactions) for 1993 of $12.70 per barrel, compared to
$16.94 per barrel for West Texas Intermediate crude oil (an industry posted
price generally indicative of spot prices for sweeter light crude oil). In
addition, the lifting costs of heavy crude oils are generally higher than the
lifting costs of light crude oils. As a result of these narrower margins, even
relatively modest changes in crude oil prices may significantly affect the
Company's revenues, results of operations, cash flows and proved reserves. In
addition, prolonged periods of high or low oil prices may have a material
effect on the Company's financial position.
 
    Crude oil prices are subject to significant changes in response to
fluctuations in the domestic and world supply and demand and other
market conditions as well as the world political situation
as it affects OPEC, the Middle East and other producing countries.
(See Items 1 and 2, "Business and Properties -- Current Markets for Oil and
Gas"). The period since mid-1990 has included some of the largest fluctuations
in oil prices in recent times, primarily due to the political unrest
in the Middle East. The actual average sales price (unhedged) received by
the Company ranged from a high of $23.92 per barrel in the fourth quarter of
1990 to a low of $9.83 per barrel for the two months ended February 28, 1994.
The Company's average sales price for its 1993 oil production was $12.93 per
barrel. Based on operating results of 1993, the Company estimates that a $1.00
per barrel increase or decrease in average sales prices would have resulted in a
corresponding $21.6 million change in 1993 income from operations and a $16.2
million change in 1993 cash flow from operating activities. The Company also
estimates that a $0.10 per Mcf increase or decrease in average sales prices
would have resulted in a corresponding $5.8 million change in 1993 income from
operations and a $4.4 million change in 1993 cash flow from operating
activities. The foregoing estimates do not give effect to changes in any other
factors, such as the effect of the Company's hedging program or depreciation and
depletion, that would result from a change in oil and natural gas prices.
 
    In the third quarter of 1990 the Company initiated a hedging program with
respect to its sales of crude oil and in the third quarter of 1992 a similar
program was initiated with respect to the Company's sales of natural gas. See
Items 1 and 2. 'Business and Properties -- Current Markets for Oil and Gas.'
 
    During 1992 and 1993, certain significant events occurred which affect the
comparability of prior periods, including the merger of Adobe with and into the
Company in May 1992, the formation of the Santa Fe Energy Trust in November 1992
and implementation of the corporate restructuring
 
                                       23
 
<PAGE>
program adopted in October 1993. The corporate restructuring program includes
(i) the concentration of capital spending in the Company's core operating areas,
(ii) the disposition of non-core assets, (iii) the elimination of the $0.04 per
share quarterly Common Stock dividend and (iv) the recognition of $38.6 million
of restructuring charges. See Note 2 to the Consolidated Financial Statements
and Items 1 and 2, 'Business and Properties -- Corporate Restructuring Program.'
In addition, the Company's results of operations for 1993 include a charge of
$99.3 million for the impairment of oil and gas properties.
 
    The Company's capital program will be concentrated in three domestic core
areas -- the Permian Basin in Texas and New Mexico, the offshore Gulf of Mexico
and the San Joaquin Valley of California -- as well as its productive areas in
Argentina and Indonesia. The domestic program includes development activities in
the Delaware and Cisco-Canyon formations in west Texas and southeast New Mexico,
a development drilling program for the offshore Gulf of Mexico natural gas
properties and relatively low risk infill drilling in the San Joaquin Valley of
California. Internationally, the program includes development of the Company's
Sierra Chata discovery in Argentina with gas sales expected to commence in early
1995 and the Salawati Basin Joint Venture in Indonesia. See Items 1 and 2.
'Business and Properties -- Domestic Development Activities' and
'--International Development Activities.'
 
    The Company's non-core asset disposition program includes the sale of its
natural gas gathering and processing assets to Hadson (completed in December
1993), the sale to Vintage of certain southern California and Gulf Coast oil and
gas producing properties (completed in November 1993) and the sale to Bridge of
certain Mid-Continent and Rocky Mountain oil and gas producing properties and
undeveloped acreage (expected to be completed during April 1994). See Items 1
and 2. 'Business and Properties -- Corporate Restructuring Program' for a
description of the transactions with Hadson, Vintage and Bridge. In the first
quarter of 1994, the Company sold the remaining 575,000 Depositary Units which
it held in Santa Fe Energy Trust (the 'Trust') for $11.3 million and its
interest in certain other oil and gas properties for $8.3 million. As a result
of the Vintage and Bridge dispositions, the Company has sold properties having
combined production during 1993 of 4.1 MBbls per day of oil and 21.7 MMcf per
day of natural gas and estimated proved reserves of approximately 16.7 MMBOE.
 
    The restructuring program also includes an evaluation of the Company's
capital and cost structures to examine ways to increase flexibility and
strengthen the Company's financial performance. In this respect, in 1994 the
Company intends to refinance a portion of its existing long-term debt and
is currently evaluating a combination of debt and equity financing arrangements
with which to effect the refinancing.
 
    In May, 1992, Adobe, an oil and gas exploration and production company, was
merged with and into the Company. The acquisition was accounted for as a
purchase and the results of operations of the properties acquired are included
in the Company's results of operations effective June 1, 1992. Pursuant to the
Adobe Merger, the Company issued 5,000,000 shares of its convertible preferred
stock and assumed approximately $175.0 million of long-term debt and other
liabilities. Pursuant to the Adobe Merger, the Company also acquired Adobe's
proved reserves and inventory of undeveloped acreage. As of December 31, 1991,
Adobe's estimated proved reserves totaled approximately 53.2 MMBOE (net of 6.9
MMBOE attributable to Adobe's ownership in certain gas plants), of which
approximately 58% was natural gas (approximately 66% of Adobe's estimated
domestic proved reserves were natural gas). Approximately 72% of the discounted
future net cash flow of Adobe's estimated domestic proved reserves was
concentrated in three areas of operation -- offshore Gulf of Mexico, onshore
Louisiana and in the Spraberry Trend in west Texas. In addition, Adobe's
international operations consisted of certain production sharing arrangements in
Indonesia, in respect of which approximately 6.0 MMBOE of estimated proved
reserves had been attributed to Adobe's interest as of December 31, 1991. The
location of the Adobe Properties enhanced the Company's
 
                                       24
 
<PAGE>
existing domestic operations and added significant operations to the Company's
international program.
 
    In November 1992, 5,725,000 Depositary Units consisting of interests in the
Trust were sold in a public offering. After payment of certain costs and
expenses, the Company received $70.1 million and 575,000 Depositary Units. For
any calendar quarter ending on or prior to December 21, 2002, the Trust will
receive additional royalty payments to the extent necessary to distribute $0.40
per Depositary Unit per quarter. The source of such payments, if needed, will be
limited to the Company's remaining royalty interest in certain of the properties
conveyed to the Trust. The aggregate amount of such payments will be limited to
$20.0 million on a revolving basis. The Company was required to make an
additional royalty payment of $362,000 with respect to the distribution made by
the Trust for operations during the quarter ended December 31, 1993. Based upon
current prices, the Company believes that a support payment will be required for
the quarter ending March 31, 1994, the amount of which has not been determined.
See Items 1 and 2. 'Business and Properties -- Santa Fe Energy Trust.'

  1993 COMPARED WITH 1992
 
    Total revenues increased approximately 2% from $427.5 million in 1992 to
$436.9 million in 1993 principally due to an increase in oil and natural gas
production offset by a decline in average oil prices. Average daily oil
production increased 7% from 62.5 MBbls in 1992 to 66.7 MBbls in 1993,
principally due to increased domestic and Indonesian production. The average
price realized per Bbl of oil during 1993 was $12.93, a decrease of 14% versus
the average price of $14.96 in 1992. Natural gas production increased 31% from
126.3 MMcf per day in 1992 to 165.4 MMcf per day in 1993, primarily reflecting
the effect of a full year's production from the Adobe Properties. Average
natural gas prices realized increased approximately 11% from $1.70 per Mcf in
1992 to $1.89 per Mcf in 1993.
 
    Production and operating costs increased $10.4 million in 1993, primarily
reflecting the effect of a full year's costs for the Adobe Properties; however,
on a BOE basis such costs declined from $5.02 per barrel in 1992 to $4.76 per
barrel in 1993. Exploration costs were $5.5 million higher than in 1992
primarily reflecting higher geological and geophysical costs and higher dry hole
costs. Depletion, depreciation and amortization ('DD&A') increased $6.4 million
in 1993 primarily reflecting a full year's expense on Adobe Properties partially
offset by reduced amortization rates with respect to certain unproved
properties. DD&A for 1993 includes $12.1 million with respect to the properties
sold to Vintage and Bridge. On a BOE basis, DD&A decreased by $0.35 per Bbl,
from $4.79 to $4.44 per Bbl. General and administrative costs increased $1.4
million principally due to a $1.8 million charge related to the adoption of
Statement of Financial Standards No. 112 -- 'Employer's Accounting for
Postemployment Benefits'. Taxes (other than income) increased by $3.0 million in
1993 primarily reflecting the effect of the Adobe Properties.
 
                                       25
 
<PAGE>
    Costs and expenses for 1993 also include $99.3 million in impairments of oil
and gas properties and $38.6 million in restructuring charges. The Company
estimates the impairments taken in 1993 will result in a reduction of DD&A in
1994 of approximately $20.0 million. The restructuring charges include losses on
property dispositions of $27.8 million, long-term debt repayment penalties of
$8.6 million and accruals of certain personnel benefits and related costs of
$2.2 million. In connection with the property dispositions effected during 1993
(See  '-- Liquidity and Capital Resources'), the Company sold properties having
combined production during 1993 of 4.1 MBbls per day of oil and 21.7 MMcf per
day of natural gas and combined estimated proved reserves of approximately 16.7
MMBOE. The Company's income from operations for 1993 includes $8.5 million with
respect to such operations.
 
    Interest income in 1993 includes $6.8 million related to a $10 million
refund received as a result of the completion of the audit of the Company's
federal income tax returns for 1971 through 1980. The decrease in interest
expenses during 1993 reflects a decrease in the Company's debt outstanding and a
$5.7 million credit related to a revision to a tax sharing agreement with the
Company's former parent. Other income and expenses of 1993 includes a $4.0
million charge related to the accrual of a contingent loss with respect to the
operations of a former affiliate of Adobe.
 
  1992 COMPARED WITH 1991
 
    Total revenues increased approximately 13% from $379.8 million in 1991 to
$427.5 million in 1992 principally due to an increase of approximately $53.2
million attributable to production from properties acquired in the Adobe Merger
and an increase of approximately $10.7 million and $10.2 million in revenues
from the Company's domestic and Argentine properties, respectively, offset in
part by a decline of $32.0 million in crude oil hedging revenues. Oil production
increased 13% from 55.5 MBbls per day in 1991 to 62.5 MBbls per day in 1992,
reflecting a 3.4 MBbl per day increase in domestic oil production and a 3.6 MBbl
per day increase in production in Argentina and Indonesia. The average price
realized per barrel of oil during 1992 decreased to $14.96, a decrease of 7%
versus the average price of $16.16 in 1991, primarily reflecting a $32.0 million
decrease in hedging revenues. Natural gas production increased 33% from 95.2
MMcf per day in 1991 to 126.3 MMcf per day in 1992 as a result of properties
acquired in the Adobe Merger. Average natural gas prices realized increased
approximately 14% from $1.49 per Mcf in 1991 to $1.70 per Mcf in 1992.
 
    Total operating expenses of the Company increased $54.6 million from $315.4
million in 1991 to $370.0 million in 1992 primarily reflecting costs associated
with the Adobe Merger. Production and operating costs in 1992 were $18.8 million
higher than in 1991, primarily reflecting costs related to the Adobe Properties
and increased fuel costs associated with the Company's EOR projects. On a BOE
basis, production and operating costs declined from $5.17 per barrel in 1991 to
$5.02 per barrel in 1992, primarily reflecting the lower cost structure of the
Adobe Properties. Exploration costs were $6.8 million higher than in 1991
primarily reflecting higher geological and geophysical costs with respect to
foreign projects. Depletion, depreciation and amortization costs were $39.7
million higher in 1992 due to the acquisition of the Adobe Properties and, to a
lesser extent, adjustments to oil and gas reserves with respect to certain
producing properties. General and administrative costs increased $3.1 million
principally due to a $1.2 million charge related to certain stock awards which
fully vested upon consummation of the Adobe Merger and certain other
merger-related costs. Taxes (other than income) decreased by $2.9 million in
1992, as a result of lower accruals with respect to property taxes. The $13.6
million gain on the disposition of properties in 1992 primarily relates to the
sale of certain royalty interest properties, in which the Company had no
remaining financial basis.
 
    The increase in interest expense during 1992 reflects the increase in debt
as a result of the Adobe Merger. Other income and expenses for 1992 includes a
$10.9 million charge for costs incurred by Adobe in connection with the Adobe
Merger and paid by Santa Fe.

LIQUIDITY AND CAPITAL RESOURCES
 
    Historically, the Company has generally funded capital and exploration
expenditures and working capital requirements from cash provided by operating
activities. Depending upon the future levels of operating cash flows, which are
significantly affected by oil and gas prices, the restrictions on additional
borrowings included in certain of the Company's debt agreements, together with
debt service requirements and dividends, may limit the cash available for future
exploration, development and acquisition activities. Net cash provided by
operating activities totaled $160.2 million in 1993, $141.5 million in 1992 and
$128.4 million in 1991; net cash used in investing activities in such periods
totaled $121.4 million, $15.9 million and $117.2 million, respectively.

     The Company's cash flow from operating activities is a function of the
volumes of oil and gas produced from the Company's properties and the sales
prices realized therefor. Crude oil and natural gas are depleting assets. Unless
the Company replaces over the long term the oil and natural gas produced from
the Company's properties, the Company's assets will be depleted over time
and its ability to service and incur debt at constant or declining prices
will be reduced. The Company's cash flow from operations for 1993 reflects an
average sales price (unhedged) for the Company's 1993 oil production of $12.93
per barrel. For the two months ended February 28, 1994, the average sales price
(unhedged) for the Company's 1994 oil production was $9.83 per barrel. If such
lower oil prices prevail throughout 1994, the Company's cash flow from operating
activities for 1994 will be significantly lower than that for 1993.
 
    In October 1993, the Company's Board of Directors adopted a broad corporate
restructuring program that focuses on the concentration of capital spending in
core areas and the disposition of non-core assets. The Company's asset
disposition program adopted in connection with the 1993 restructuring program
has been substantially completed by the asset sales to Hadson, Vintage and
Bridge (expected to close in April 1994), the sale of the 575,000 Depositary
Units in the Trust and the sale of its interest in certain other oil and gas
properties. As a result of such sales, the Company sold a total of 16.7 MMBOE of
proved reserves and undeveloped acreage for a total of approximately $111.0
million, and sold certain gas gathering and processing facilities for Hadson
securities.
 
    As a part of the 1993 restructuring program, the Company eliminated its
$0.04 per share quarterly dividend on its Common Stock and announced that it
might spend up to $240 million in 1994 on an accelerated capital program.
However, as a result of the depressed crude oil prices that have prevailed since
November 1993, the Company, consistent with industry practice, is considering
deferring some of its capital projects in order to prudently manage its cash
flow available in the near term. Based on current market conditions, the Company
estimates that 1994 capital expenditures may total between $100 million and $160
million, with the actual amount to be determined by the Company based upon
numerous factors outside its control, including, without limitation, prevailing
oil and natural gas prices and the outlook therefor.
 
    The Company is a party to several long-term and short-term credit agreements
which restrict the Company's ability to take certain actions, including
covenants that restrict the Company's ability to incur additional indebtedness
and to pay dividends on its capital stock. For a description of such existing
credit agreements, see Note 7 to the Consolidated Financial Statements.

    Effective March 16, 1994, the Company entered into an Amended and Restated
Revolving Credit Agreement (the "Bank Facility") which consists of a five year
secured revolving credit agreement maturing December 31, 1998 ("Facility A") and
and a three year unsecured revolving credit facility maturing December 31, 1996
("Facility B"). The aggregate borrowing limits under the terms of the Bank
Facility are $125.0 million (up to $90.0 million under Facility A and up to
$35.0 million under Facility B). Under certain circumstances, the aggregate
borrowing limits under the terms of the Bank Facility may be increased to $175.0
million (up to $90.0 million under Facility A and up to $85.0 million under
Facility B). Interest rates under the Bank Facility are tied to LIBOR or the
bank's prime rate with the actual interest rate reflecting certain ratios based
upon the Company's ability to repay its outstanding debt and the value and
projected timing of production of the Company's oil and gas reserves. These and
other similar ratios will also affect the Company's ability to borrow under the
Bank Facility and the timing and amount of any required repayments and
corresponding commitment reductions. The Bank Facility replaces the Revolving
and Term Credit Agreement discussed in Note 7 to the Consolidated Financial
Statements. 

EFFECTS OF INFLATION
 
    Inflation during the three years ended December 31, 1993 has had little
effect on the Company's capital costs and results of operations.
 
ENVIRONMENTAL MATTERS
 
    Almost all phases of the Company's oil and gas operations are subject to
stringent environmental regulation by governmental authorities. Such regulation
has increased the costs of planning, designing, drilling, installing, operating
and abandoning oil and gas wells and other facilities. The Company has expended
significant financial and managerial resources to comply with such regulations.
Although the Company believes its operations and facilities are in general
compliance with applicable environmental regulations, risks of substantial costs
and liabilities are inherent in oil and gas operations. It is possible that
other developments, such as increasingly strict environmental laws, regulations
and enforcement policies or claims for damages to property, employees, other
persons and the environment resulting from the Company's operations, could
result in significant costs and liabilities in the future. As it has done in the
past, the Company intends to fund its cost of environmental compliance from
operating cash flows. See also, Items 1 and 2. 'Business and Properties -- Other
Business Matters -- Environmental Regulation' and Note 12 to the Consolidated
Financial Statements.

DIVIDENDS
 
    Dividends on the Company's convertible preferred stock are cumulative at an
annual rate of $1.40 per share. No dividends may be declared or paid with
respect to the Company's common stock if any dividends with respect to the
convertible preferred stock are in arrears. As described elsewhere herein, the
Company has eliminated the payment of its $0.04 per share quarterly dividend on
its common stock. The determination of the amount of future cash dividends, if
any, to be declared and paid on the Company's common stock is in the sole
discretion of the Company's Board of Directors and will depend on dividend
requirements with respect to the convertible preferred stock, the Company's
financial condition, earnings and funds from operations, the level of capital
and exploration expenditures, dividend restrictions in financing agreements,
future business prospects and other matters the Board of Directors deems
relevant.

To the Board of Directors and Shareholders of
Santa Fe Energy Resources, Inc.
 
In our opinion, the consolidated financial statements listed in the index
appearing under Item 14(a)(1) and (2) on page 30 present fairly, in all material
respects, the financial position of Santa Fe Energy Resources, Inc. and its
subsidiaries at December 31, 1993 and 1992, and the results of their operations
and their cash flows for each of the three years in the period ended December
31, 1993, in conformity with generally accepted accounting principles. These
financial statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these statements in accordance with
generally accepted auditing standards which 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,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
(1)  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  PRINCIPLES OF CONSOLIDATION
 
    The consolidated financial statements of Santa Fe Energy Resources, Inc.
('Santa Fe' or the 'Company') and its subsidiaries include the accounts of all
wholly owned subsidiaries. The accounts of Santa Fe Energy Partners, L.P., (the
'Partnership') are included on a proportional basis until September 1993 when
Santa Fe purchased all the Partnership's outstanding Depositary Units and
undeposited LP Units other than those units held by Santa Fe and its affiliates.
 
    On September 27, 1993 the Company exercised its right under the Agreement of
Limited Partnership to purchase all of the Partnership's outstanding Depositary
Units and undeposited LP Units, other than those units held by the Company and
its affiliates, at a redemption price of $4.9225 per unit. Consideration for the
5,749,500 outstanding units totalled $28.3 million. The acquisition of the units
has been accounted for as a purchase and the results of operations of the
Partnership attributable to the units acquired is included in the Company's
results of operations with effect from October 1, 1993. The purchase price has
been allocated primarily to oil and gas properties.
 
    References herein to the 'Company' or 'Santa Fe' relate to Santa Fe Energy
Resources, Inc., individually or together with its consolidated subsidiaries;
references to the 'Partnership' relate to Santa Fe Energy Partners, L.P.
 
    All significant intercompany accounts and transactions have been eliminated.
Prior years' financial statements include certain reclassifications to conform
to current year's presentation.
 
  OIL AND GAS OPERATIONS
 
    The Company follows the successful efforts method of accounting for its oil
and gas exploration and production activities. Costs (both tangible and
intangible) of productive wells and development dry holes, as well as the cost
of prospective acreage, are capitalized. The costs of drilling and equipping
exploratory wells which do not find proved reserves are expensed upon
determination that the well does not justify commercial development. Other
exploratory costs, including geological and geophysical costs and delay rentals,
are charged to expense as incurred.
 
    Depletion and depreciation of proved properties are computed on an
individual field basis using the unit-of-production method based upon proved oil
and gas reserves attributable to the field. Certain other oil and gas properties
are depreciated on a straight-line basis. Individual proved properties are
reviewed periodically to determine if the carrying value of the field exceeds
the estimated undiscounted future net revenues from proved oil and gas reserves
attributable to the field. Based on this review and the continuing evaluation of
development plans, economics and other factors, if appropriate, the Company
records impairments (additional depletion and depreciation) to the extent that
the carrying value exceeds the estimated undiscounted future net revenues. Such
impairments totaled $99.3 million in 1993 and there were none in 1992 and 1991.
 
    The Company provides for future abandonment and site restoration costs with
respect to certain of its oil and gas properties. The Company estimates that
with respect to these properties such future costs total approximately $24.7
million and such amount is being accrued over the expected life of the
properties. At December 31, 1993 Accumulated Depletion, Depreciation,
Amortization and Impairment includes $14.6 million with respect to such costs.
 
    The value of undeveloped acreage is aggregated and the portion of such costs
estimated to be nonproductive, based on historical experience, is amortized to
expense over the average holding period. Additional amortization may be
recognized based upon periodic assessment of prospect evaluation results. The
cost of properties determined to be productive is transferred to proved
 
                                       36
 
<PAGE>
                        SANTA FE ENERGY RESOURCES, INC.
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
properties; the cost of properties determined to be nonproductive is charged to
accumulated amortization.
 
    Maintenance and repairs are expensed as incurred; major renewals and
improvements are capitalized. Gains and losses arising from sales of properties
are included in income currently.
 
  REVENUE RECOGNITION
 
    Revenues from the sale of petroleum produced are generally recognized upon
the passage of title, net of royalties and net profits interests. Crude oil
revenues include the effect of hedging transactions; see Note 12 -- Commitments
and Contingencies -- Crude Oil Hedging Program. Crude oil revenues also include
the value of crude oil consumed in operations with an equal amount charged to
operating expenses. Such amounts totalled $15.4 million in 1991, $4.8 million in
1992 and $1.2 million in 1993.
 
    Revenues from natural gas production are generally recorded using the
entitlement method, net of royalties and net profits interests. Sales proceeds
in excess of the Company's entitlement are included in Deferred Revenues and the
Company's share of sales taken by others is included in Other Assets. At
December 31, 1993 the Company's deferred revenues for sales proceeds received in
excess of the Company's entitlement was $6.8 million with respect to 5.2 MMcf
and the asset related to the Company's share of sales taken by others was $3.9
million with respect to 2.7 MMcf. Natural gas revenues are net of the effect of
hedging transactions; see Note 12 -- Commitments and Contingencies -- Natural
Gas Hedging Program.
 
    Revenues from crude oil marketing and trading represent the gross margin
resulting from such activities. Revenues from such activities are net of costs
of sales of $210.5 million in 1991, $247.3 million in 1992 and $225.9 million in
1993.
 
    Revenues from natural gas systems are net of the cost of natural gas
purchased and resold. Such costs totalled $43.8 million in 1992 and $49.9
million in 1993.
 
  EARNINGS PER SHARE
 
    Earnings per share are based on the weighted average number of common shares
outstanding during the year.
 
  ACCOUNTS RECEIVABLE
 
    Accounts Receivable relates primarily to sales of oil and gas and amounts
due from joint interest partners for expenditures made by the Company on behalf
of such partners. The Company reviews the financial condition of potential
purchasers and partners prior to signing sales or joint interest agreements. At
December 31, 1993 and 1992 the Company's allowance for doubtful accounts
receivable, which is reflected in the consolidated balance sheet as a reduction
in accounts receivable, totaled $6.3 million and $5.0 million, respectively.
Accounts receivable totalling $0.2 million, $1.1 million and $0.1 million were
written off as uncollectible in 1991, 1992 and 1993, respectively.
 
  INVENTORIES
 
    Inventories are valued at the lower of cost (average price or first-in,
first-out) or market. Crude oil inventories at December 31, 1993 and 1992 were
$1.1 million and $1.5 million, respectively, and materials and supplies
inventories at such dates were $7.6 million and $3.3 million, respectively.
 
  ENVIRONMENTAL EXPENDITURES
 
    Environmental expenditures relating to current operations are expensed or
capitalized, as appropriate, depending on whether such expenditures provide
future economic benefits. Liabilities are
 
                                       37
 
<PAGE>
                        SANTA FE ENERGY RESOURCES, INC.
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
recognized when the expenditures are considered probable and can be reasonably
estimated. Measurement of liabilities is based on currently enacted laws and
regulations, existing technology and undiscounted site-specific costs.
Generally, such recognition coincides with the Company's commitment to a formal
plan of action.
 
  INCOME TAXES
 
    The Company follows the asset and liability approach to accounting for
income taxes. Deferred tax assets and liabilities are determined using the tax
rate for the period in which those amounts are expected to be received or paid,
based on a scheduling of temporary differences between the tax bases of assets
and liabilities and their reported amounts. Under this method of accounting for
income taxes, any future changes in income tax rates will affect deferred income
tax balances and financial results.
 
(2) CORPORATE RESTRUCTURING PROGRAM
 
    In October 1993 the Company's Board of Directors endorsed a broad corporate
restructuring program that focuses on the disposition of non-core assets, the
concentration of capital spending in core areas, the refinancing of certain
long-term debt and the elimination of the payment of its $0.04 per share
quarterly dividend on common stock.
 
    In implementing the restructuring program the Company recorded a
nonrecurring charge of $38.6 million in 1993 comprised of (1) losses on property
dispositions of $27.8 million: (2) long-term debt repayment penalties of $8.6
million; and (3) accruals for certain personnel benefits and related costs of
$2.2 million.
 
    The Company's non-core asset disposition program includes the sale of its
natural gas gathering and processing assets to Hadson Corporation ('Hadson'),
the sale to Vintage Petroleum, Inc. of certain southern California and Gulf
Coast oil and gas producing properties and the sale to Bridge Oil (U.S.A.) Inc.
('Bridge') of certain Mid-Continent and Rocky Mountain oil and gas producing
properties and undeveloped acreage. The Company also plans to dispose of other
non-core oil and gas properties during 1994.
 
    In 1994 the Company intends to refinance a portion of its existing long-term
debt and is currently evaluating a combination of debt and equity financing
arrangements with which to effect the refinancing.
 
    SALE TO HADSON.  In December 1993 the Company completed a transaction with
Hadson under the terms of which the Company sold the common stock of Adobe Gas
Pipeline Company ('AGPC'), a wholly-owned subsidiary which held the Company's
natural gas gathering and processing assets, to Hadson in exchange for Hadson
11.25% preferred stock with a face value of $52.0 million and 40% of Hadson's
common stock. In addition, the Company signed a seven-year gas sales contract
under the terms of which Hadson will market substantially all of the Company's
domestic natural gas production at market prices as defined by published monthly
indices for relevant production locations.
 
    The Company accounted for the sale as a non-monetary transaction and the
investment in Hadson has been valued at $56.2 million, the carrying value of the
Company's investment in AGPC. The Company's investment in Hadson is being
accounted for on the equity basis. At December 31, 1993 the Company's investment
in Hadson's common stock exceeded the net book value attributable to such common
shares by approximately $11.3 million. The Company's income from operations for
1993 includes $1.6 million attributable to the assets sold to Hadson.
 
    SALE TO VINTAGE.  In November 1993 the Company completed the sale of certain
southern California and Gulf Coast producing properties for net proceeds
totalling $41.3 million in cash, $31.5
 
                                       38
 
<PAGE>
                        SANTA FE ENERGY RESOURCES, INC.
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
million of which was collected in 1993. The Company's income from operations for
1993 includes $2.7 million attributable to the assets sold to Vintage.
 
    SALE TO BRIDGE.  In December 1993 the Company signed a Purchase and Sales
Agreement with Bridge under the terms of which Bridge will purchase certain
Mid-Continent and Rocky Mountain producing and nonproducing oil and gas
properties. The sale price of $51.0 million, subject to certain adjustments,
will be received by the Company either in the form of cash plus 10% of the
outstanding shares of Bridge, following the contemplated public offering of that
stock in the first quarter of 1994, or entirely in cash. The transaction is
expected to close in the second quarter of 1994.
 
    The net book value of these assets is included in Assets Held for Sale at
December 31, 1993. The Company's income from operations for 1993 includes $5.8
million attributable to the assets to be sold to Bridge.
 
    OTHER DISPOSITIONS.  The Company has identified certain other oil and gas
properties which it plans to dispose of in 1994. The estimated realizable value
of these properties, $1.0 million, is included in Assets Held for Sale at
December 31, 1993. In the first quarter of 1994 the Company sold its interest in
certain other oil and gas properties for $8.3 million.
 
(3)  MERGER WITH ADOBE RESOURCES CORPORATION
 
    On May 19, 1992 Adobe Resources Corporation ('Adobe'), an oil and gas
exploration and production company, was merged with and into Santa Fe (the
'Merger'). The acquisition has been accounted for as a purchase and the results
of operations of the properties acquired (the 'Adobe Properties') are included
in Santa Fe's results of operations effective June 1, 1992.
 
    To consummate the Merger, the Company issued 24.9 million shares of common
stock valued at $205.5 million, 5.0 million shares of convertible preferred
stock valued at $80.0 million, assumed long-term bank debt and other liabilities
of $140.0 million and $35.0 million, respectively, and incurred $13.8 million in
related costs. The Company also recorded a $19.7 million deferred tax liability
with respect to the difference between the book and tax basis in the assets
acquired. Certain merger-related costs incurred by Adobe and paid by Santa Fe
totaling $10.9 million were charged to income in the second quarter of 1992.
 
    The Merger constituted a 'change of control' as defined in certain of the
Company's employee benefit plans and employment agreements (see Notes 10 and
12).
 
    In a separate transaction in January 1992, the Company purchased three
producing properties from Adobe for $14.2 million.
 
(4)  SANTA FE ENERGY TRUST
 
    In November 1992 5,725,000 Depository Units ('Trust Units'), each consisting
of beneficial ownership of one unit of undivided beneficial interest in the
Santa Fe Energy Trust (the 'Trust') and a $20 face amount beneficial ownership
interest in a $1,000 face amount zero coupon United States Treasury obligation
maturing on or about February 15, 2008, were sold in a public offering. The
Trust consists of certain oil and gas properties conveyed by Santa Fe. A total
of $114.5 million was received from public investors, of which $38.7 million was
used to purchase the Treasury obligations and $5.7 million was used to pay
underwriting commissions and discounts. Santa Fe received the remaining $70.1
million and 575,000 Trust Units. A portion of the proceeds received by the
Company was used to retire $30.0 million of the debt incurred in connection with
the Merger and the remainder will be used for general corporate purposes
including possible acquisitions.
 
    For any calendar quarter ending on or prior to December 31, 2002, the Trust
will receive additional royalty payments to the extent that it needs such
payments to distribute $0.40 per
 
                                       39
 
<PAGE>
                        SANTA FE ENERGY RESOURCES, INC.
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
Depository Unit per quarter. The source of such additional royalty payments, if
needed, will be limited to the Company's remaining royalty interest in certain
of the properties conveyed to the Trust. If such additional payments are made,
certain proceeds otherwise payable to the Trust in subsequent quarters may be
reduced to recoup the amount of such additional payments. The aggregate amount
of the additional royalty payments (net of any amounts recouped) will be limited
to $20.0 million on a revolving basis.
 
    At December 31, 1993 the Company held 575,000 Trust Units. At December 31,
1993 Accounts Receivable includes $0.2 million due from the Trust and Accounts
Payable includes $1.9 million due to the Trust. In the first quarter of 1994 the
Company sold the Trust Units for $11.3 million, the Company's investment in the
Trust Units, $10.4 million, is included in Assets Held for Sale at December 31,
1993.
 
(5)  ACQUISITIONS OF OIL AND GAS PROPERTIES
 
    In January 1991 the Company completed the purchase of Mission Operating
Partnership, L.P.'s ('Mission') interest in certain oil and gas properties,
effective from November 1, 1990, for approximately $55.0 million. The Company
formed a partnership, with an institutional investor as a limited partner, to
acquire and operate the properties. The investor contributed $27.5 million for a
50% interest in the partnership, which will be reduced to 15% upon the occurence
of payout. Payout will occur when the investor has received distributions from
the partnership totalling an amount equal to its original contribution plus a
12% rate of return on such contribution. Prior to payout, the Company will bear
100% of the capital expenditures of the partnership. Under the terms of the
partnership agreement a total of $36.8 million must be expended on development
of the property by the year 2000, $12.4 million of which had been expended
through the end of 1993.
 
    The Company funded $16.8 million of its share of the purchase of the
properties with the assumption of a term loan and paid the remainder from
working capital. The Company has given the lender the equivalent of an
overriding royalty interest in certain production from the properties. The
royalty is payable only if such production occurs and is limited to a maximum of
$3.0 million.
 
    In June 1991 the Company acquired a 10% interest in a producing field in
Argentina for approximately $18.3 million and in October 1991 purchased an
additional 8% interest in the field for approximately $15.7 million. The Company
financed $17.8 million of the total purchase price with loans from an Argentine
bank. The Company has agreed to spend approximately $16.7 million over a
five-year period on development and maintenance of the field.

    On April 11, 1990 SFER issued $365.0 million of serial unsecured Senior
Notes with interest rates averaging 10.35%. The Note Agreement pursuant to which
the Senior Notes were issued includes certain covenants which, among other
things, restrict the Company's ability to incur additional indebtedness and to
pay dividends. Under the terms of the Note Agreement, at December 31, 1993 the
Company had the ability to incur at least $64.0 million in additional long-term
debt and pay $26.0 million in dividends and other restricted payments. At
December 31, 1993 $340.0 million in Senior Notes were outstanding and are to be
repaid, $30.0 million in 1994 and 1995, $35.0 million in 1996 through 1998 and
$25.0 million per year in 1999 through 2005.
 
    In January 1991 the Company executed a $16.8 million term-loan agreement,
with interest at 9.0%, in connection with the purchase of certain producing
properties from Mission. At December 31, 1993 $12.6 million was outstanding
under the terms of the agreement and is to be repaid $1.2 million in 1994 and

    In June 1991 the Company borrowed $10.4 million from an Argentine bank in
connection with the purchase of an interest in a producing oil field in
Argentina. The loan bore interest at the higher of 12% or the interbank offering
rate plus 2%. In October 1991 the Company borrowed an additional $7.8 million in
connection with the purchase of an additional interest in the field. The second
loan bore interest at the higher of rates ranging from 13.4% to 14.0% or the
London Interbank Offering Rate ('LIBOR') plus 2%. During 1993 the two loans were
combined in a new loan which bears interest at the higher of 13.06% or LIBOR
plus 2%.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
    In connection with the Merger the Company entered into a $195.0 million
Revolving and Term Credit Agreement (the 'Credit Agreement') with a group of
banks. Upon consummation of the Merger the Company drew down the $145.0 million
available under the term loan feature of the Credit Agreement and repaid the
$140.0 million of long-term debt assumed in the Merger. The borrowings under the
term loan feature of the Credit Agreement are secured by properties acquired in
the Merger. Interest rates on borrowings are determined from time to time and at
December 31, 1993 amounts outstanding under the term loan feature bore interest
at an average of 5.5% per annum.
 
    In April 1993 the term loan feature was amended to allow the Company to make
voluntary prepayments and reborrowings. At December 31, 1993 the balance
outstanding under the term loan feature was $50.0 million and the total amount
available under the term loan feature, including amounts then outstanding, was
$87.7 million. The amount available will be reduced, in semi-annual increments,
to $48.6 million in December 31, 1994 and $24.3 million at December 31, 1995.
The Credit Agreement expires December 31, 1996. In certain circumstances,
primarily related to the sale of properties securing the loans, the amount
available may be reduced or the Company may be required to make mandatory
repayments. The Company is currently negotiating an amendment to the Credit
Agreement which would extend the maturities and under certain circumstances
increase the amount available for borrowings.
 
    Under the revolving credit feature of the Credit Agreement the Company may
borrow and issue letters of credit totalling up to $50.0 million. Borrowings
under the revolving credit feature are unsecured but are subject to compliance
with covenants identical to existing covenants under the Company's other
long-term debt agreeements including covenants related to debt incurrence,
dividends and other restricted payments, investments and limitations on liens,
mergers and sales of assets. In addition, the Company must comply annually with
certain borrowing base coverage ratios relating to projected cash flows from oil
and gas revenues. The amount available under the revolving credit feature will
be reduced to $10.0 million on February 28, 1994 and this feature expires on
February 28, 1995. At December 31, 1993, the Company had $8.7 million in letters
of credit outstanding under the revolving credit feature of the Credit
Agreement.
 
    The Company has two uncommitted lines of credit totalling $35.0 million
which is used to meet short-term cash needs. Interest rates on borrowings under
this line of credit is typically lower than rates paid under the Credit
Agreement. At December 31, 1993 no amounts were outstanding under these lines of
credit.
 
    In December 1991 the Partnership issued two promissory notes for a total of
$5.5 million in connection with the purchase of certain surface lands. The
notes, which bore interest at 10.0%, were retired in 1993. The Company's
proportionate share of such debt at December 31, 1992 was $4.2 million.
 
    At December 31, 1993 and 1992 the Partnership had $32.0 million and $44.0
million, respectively, outstanding under the terms of long-term credit agreement
which expires in 1997. The Company's proportionate share of such debt totaled
$40.6 million at December 31, 1992. Interest on 65% of principal amount
outstanding is fixed at 10.13% with interest on the remaining amount outstanding
at floating rates which averaged 4.3% in 1993 and 5.46% in 1992. The credit
agreement imposes certain restrictions on future indebtedness and the transfer
or sale of principal properties and requires the maintenance of certain
financial ratios to avoid collateralization or default.

purchaser would have a material adverse effect on its financial position since
the Company believes alternative sales arrangements could be made on relatively
comparable terms.

(9)  CONVERTIBLE PREFERRED STOCK
 
    The convertible preferred stock issued in connection with the Merger is
non-voting and entitled to receive cumulative cash dividends at an annual rate
equivalent to $1.40 per share. The holders of the convertible preferred shares
may, at their option, convert any or all such shares into 1.3913 shares of the
Company's common stock. The Company may, at any time after the fifth anniversary
of the effective date of the Merger and upon the occurrence of a 'Special
Conversion Event', convert all outstanding shares of convertible preferred stock
into common stock at the initial conversion rate of 1.3913 shares of common
stock, subject to certain adjustments, plus additional shares in respect to
accrued and unpaid dividends. A Special Conversion Event is deemed to have
occurred when the average daily closing price for a share of the Company's
common stock for 20 of 30 consecutive trading days equals or exceeds 125% of the
quotient of $20.00 divided by the then applicable conversion rate (approximately
$18.00 per share at a conversion rate of 1.3913).
 
    Upon the occurrence of the 'First Ownership Change' of Santa Fe, each holder
of shares of convertible preferred stock shall have the right, at the holder's
option, to elect to have all of such holder's shares redeemed for $20.00 per
share plus accrued and unpaid interest and dividends. The First Ownership Change
shall be deemed to have occurred when any person or group, together with any
affiliates or associates, becomes the beneficial owner of 50% or more of the
outstanding common stock of Santa Fe.
 
(10)  SHAREHOLDERS' EQUITY
 
  COMMON STOCK
 
    In 1991, 1992 and 1993 the Company issued 1.1 million previously unissued
shares of common stock in connection with certain employee benefit and
compensation plans. Also in 1992, the Company issued 24.9 million previously
unissued shares of common stock in connection with the Merger.
 
    The Company declared dividends to common shares of $0.16 per share in 1991
and 1992 and $0.12 per share in 1993.
 
  PREFERRED STOCK
 
    The Board of Directors of the Company is empowered, without approval of the
shareholders, to cause shares of preferred stock to be issued in one or more
series, and to determine the number of shares in each series and the rights,
preferences and limitations of each series. Among the specific matters which may
be determined by the Board of Directors are: the annual rate of dividends; the
redemption price, if any; the terms of a sinking or purchase fund, if any; the
amount payable in the event of any voluntary liquidation, dissolution or winding
up of the affairs of the Company; conversion rights, if any; and voting powers,
if any.
 
  ACCUMULATED DEFICIT
 
    At December 31, 1993 Accumulated Deficit included dividends in excess of
retained earnings of $89.8 million.
 
  1990 INCENTIVE STOCK COMPENSATION PLAN
 
    The Company has adopted the Santa Fe Energy Resources 1990 Incentive Stock
Compensation Plan (the 'Plan') under the terms of which the Company may grant
options and awards with respect to no more than 5,000,000 shares of common stock
to officers and key employees.
 
    Options granted in 1991 and prior are fully vested and expire in 2000.

percent two years after grant and as to the entire amount three years after
grant. The options granted in 1993 have a ten year term and vest as to 50
percent 5 years after grant, as to a cumulative 75 percent 6 years after grant
and as to the entire amount 7 years after grant. The options are exercisable on
an accelerated basis beginning one year and ending three years after grant in
certain circumstances. If the market value per share of the Company's common
stock (sustained in all events for at least 60 days) exceeds $15, 25 percent of
the options shall become exercisable; in the event the market value per share
exceeds $20, 50 percent of the options shall become exercisable; and in the
event the market value exceeds $25, 100 percent shall become exercisable.
Unexercised options would be forfeited in the event of voluntary or involuntary
termination. Vested options are exercisable for a period of one year following
termination due to death, disability or retirement. In the event of termination
by the Company for any reason there is no prorata vesting of unvested options.
 
    The following table reflects activity with respect to Non-Qualified Stock
Options during 1991 through 1993:

grants.
 
    A 'Phantom Unit' is the right to receive a cash payment in an amount equal
to the average trading price of the shares of common stock at the time the award
becomes payable. Awards are made for a specified period and are dependent upon
continued employment and the achievement of performance objectives established
by the Company. In December 1990 the Company awarded 211,362 Phantom Units and
in December 1991 313,262 shares of restricted stock were issued in exchange for
such units. Compensation expense is recognized over the period the awards are
earned based on the market price of the restricted stock on the date it was
issued ($8.00 per share). During 1990 and 1991 $0.2 million and $0.8 million,
respectively, were charged to expense with respect to such awards. The
unamortized portion of the award at December 31, 1991 ($1.4 million) was
reflected in Shareholders' Equity. The consummation of the Merger resulted in a
'change of control' as defined in the Plan and resulted in the vesting of the
awards and $1.4 million in compensation expense was recognized in 1992.
 
    In 1993 the Company issued 6,432 shares of restricted stock to certain
employees and 118,039 common shares in accordance with the terms of certain
other employee compensation plans.

(11)  PENSION AND OTHER EMPLOYEE BENEFIT PLANS
 
  PENSION PLANS
 
    Prior to the Spin-Off the Company was included in certain non-contributory
pension plans of SFP. The Santa Fe Pacific Corporation Retirement Plan (the 'SFP
Plan') covered substantially all of the Company's officers and salaried
employees who were not covered by collective bargaining agreements. The Santa Fe
Pacific Corporation Supplemental Retirement Plan was an unfunded plan which
provided supplementary benefits, primarily to senior management personnel.
 
    The Company adopted, effective as of the date of the Spin-Off, a defined
benefit retirement plan (the 'SFER Plan') covering substantially all salaried
employees not covered by collective bargaining agreements and a nonqualified
supplemental retirement plan (the 'Supplemental Plan'). The Supplemental Plan
will pay benefits to participants in the SFER Plan in those instances where the
SFER Plan formula produces a benefit in excess of limits established by ERISA
and the Tax Reform Act of 1986. Benefits payable under the SFER Plan are based
on years of service and compensation during the five highest paid years of
service during the ten years immediately preceding retirement. Benefits accruing
to the Company's employees under the SFP Plan have been assumed by the SFER
Plan. The Company's funding policy is to contribute annually not less than the
minimum required by ERISA and not more than the maximum amount deductible for
income tax purposes. In the fourth quarter of 1993 the Company established a new
pension plan with respect to certain persons employed in foreign locations.
 
    The following table sets forth the funded status of the SFER Plan and the
Supplemental Plan at December 31, 1993 and 1992 (in millions of dollars):

    The Company also sponsors a pension plan covering certain hourly-rated
employees in California (the 'Hourly Plan'). The Hourly Plan provides benefits
that are based on a stated amount for each year of service. The Company annually
contributes amounts which are actuarially determined to provide the Hourly Plan
with sufficient assets to meet future benefit payment requirements.
 
    The following table sets forth the components of pension expense for the
Hourly Plan for the years 1993, 1992 and 1991 (in millions of dollars):

  POSTRETIREMENT BENEFITS OTHER THAN PENSIONS
 
    The Company provides health care and life insurance benefits for
substantially all employees who retire under the provisions of a
Company-sponsored retirement plan and their dependents. Participation in the
plans is voluntary and requires a monthly contribution by the employee.
Effective January 1, 1993 the Company adopted the provisions of SFAS No.
106 -- 'Employers' Accounting for Postretirement Benefits Other Than Pensions'.
The Statement requires the accrual, during the years the employee renders
service, of the expected cost of providing postretirement benefits to the
employee and the employee's beneficiaries and covered dependents. The following
table sets forth the plan's funded status at December 31, 1993 and January 1,
1993 (in millions of dollars):

    The Company's net periodic postretirement benefit cost for 1993 includes the
following components (in millions of dollars):
 
Service costs----------------------------------------          0.3
Interest costs---------------------------------------          0.4
Amortization of unrecognized transition
  obligation-----------------------------------------          0.3

    In periods prior to 1993 the cost to the Company of providing health care
and life insurance benefits for qualified retired employees was recognized as
expenses when claims were paid. Such amounts totalled $0.4 million in 1991 and
$0.3 million in 1992.
 
    Estimated costs and liabilities have been developed assuming trend rates for
growth in future health care costs beginning with 10% for 1993 graded to 6%
(5.5% for post age 65) by the year 2000 and remaining constant thereafter.
Increasing the assumed health care cost trend rate by one percent each year
would increase the accumulated postretirement benefit obligation as of December
31, 1993 by $0.9 million and the aggregate of the service cost and interest cost
components of the net periodic postretirement benefit cost for 1994 by $0.2
million.
 
  SAVINGS PLAN
 
    The Company has a savings plan, which became effective November 1, 1990,
available to substantially all salaried employees and intended to qualify as a
deferred compensation plan under Section 401(k) of the Internal Revenue Code
(the '401(k) Plan'). The Company will match employee contributions for an amount
up to 4% of each employee's base salary. In addition, if at the end of each
 
                                       48

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
fiscal year the Company's performance for such year has exceeded certain
predetermined criteria, each participant will receive an additional matching
contribution equal to 50% of the regular matching contribution. The Company's
contributions to the 401(k) Plan, which are charged to expense, totaled $1.2
million in 1991, $1.3 million in 1992 and $1.5 million in 1993. In the fourth
quarter of 1993 the Company established a new savings plan with respect to
certain personnel employed in foreign locations.
 
  OTHER POSTEMPLOYMENT BENEFITS
 
    In the fourth quarter of 1993 the Company adopted SFAS No.
112 -- 'Employers' Accounting for Postemployment Benefits'. The Statement
requires the accrual of the estimated costs of benefits provided by an employer
to former or inactive employees after employment but before retirement. Such
benefits include salary continuation, supplemental unemployment benefits,
severance benefits, disability-related benefits, job training and counseling and
continuation of benefits such as health care and life insurance coverage. The
adoption of SFAS No. 112 resulted in a charge to earnings of $1.8 million in
1993.
 
(12)  COMMITMENTS AND CONTINGENCIES
 
  CRUDE OIL HEDGING PROGRAM
 
    In the third quarter of 1990, the Company initiated a hedging program
designed to provide a certain minimum level of cash flow from its sales of crude
oil. Settlements were included in oil revenues in the period the oil is sold. In
the year ended December 31, 1990 hedges resulted in a reduction in oil revenues
of $10.7 million; in 1991 hedges resulted in an increase in oil revenues of
$41.7 million and in 1992 hedges resulted in an increase in oil revenues of $9.7
million. The Company had no open crude oil hedging contracts during 1993.
 
  NATURAL GAS HEDGING PROGRAM
 
    In the third quarter of 1992 the Company initiated a hedging program with
respect to its sales of natural gas. The Company has used various instruments
whereby monthly settlements are based on the differences between the price or
range of prices specified in the instruments and the settlement price of certain
natural gas futures contracts quoted on the New York Mercantile Exchange. In
instances where the applicable settlement price is less than the price specified
in the contract, the Company receives a settlement based on the difference; in
instances where the applicable settlement price is higher than the specified
prices the Company pays an amount based on the difference. The instruments
utilized by the Company differ from futures contracts in that there is no
contractual obligation which requires or allows for the future delivery of the
product. In 1992 and 1993 hedges resulted in a reduction in natural gas revenues
of $0.5 million and $8.2 million, respectively.
 
    At December 31, 1993 the Company had two open natural gas hedging contracts
covering approximately 1.2 Bcf during the six month period beginning March 1994.
The 'approximate break-even price' (the average of the monthly settlement prices
of the applicable futures contracts which would result in no settlement being
due to or from the Company) with respect to such contracts is approximately
$1.82 per Mcf. In addition, certain parties hold options on contracts covering
approximately 4.8 Bcf during the seven month period beginning March 1994 at an
approximate break even price of $1.90 per Mcf. The Company has no other
outstanding natural gas hedging instruments.
 
  INDEMNITY AGREEMENT WITH SFP
 
    At the time of the Spin-Off, the Company and SFP entered into an agreement
to protect SFP from federal and state income taxes, penalties and interest that
would be incurred by SFP if the Spin-off were determined to be a taxable event
resulting primarily from actions taken by the Company during a one-year period
that ended December 4, 1991. If the Company were required to make
 
                                       49

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
payments pursuant to the agreement, such payments could have a material adverse
effect on its financial condition; however, the Company does not believe that it
took any actions during such one-year period that would have such an effect on
the Spin-Off.
 
  ENVIRONMENTAL REGULATION
 
    Federal, state and local laws and regulations relating to environmental
quality control affect the Company in all of its oil and gas operations. The
Company has been identified as one of over 250 potentially responsible parties
('PRPs') at a superfund site in Los Angeles County, California. The site was
operated by a third party as a waste disposal facility from 1948 until 1983. The
Environmental Protection Agency ('EPA') is requiring the PRPs to undertake
remediation of the site in several phases, which include site monitoring and
leachate control, gas control and final remediation. In 1989, the EPA and a
group of the PRPs entered into a consent decree covering the site monitoring and
leachate control phases of remediation. The Company is a member of the group
that is responsible for carrying out this first phase of work, which is expected
to be completed in five to eight years. The maximum liability of the group,
which is joint and several for each member of the group, for the first phase is
$37.0 million, of which the Company's share is expected to be approximately $2.4
million ($1.3 million after recoveries from working interest participants in the
unit at which the wastes were generated) payable over the period that the phase
one work is performed. The EPA and a group of PRPs of which the Company is a
member have also entered into a subsequent consent decree (which has not been
finally entered by the court) with respect to the second phase of work (gas
control). The liability of this group has not been capped, but is estimated to
be $130.0 million. The Company's share of costs of this phase, however, is
expected to be approximately of the same magnitude as that of the first phase
because more parties are involved in the settlement. The Company has provided
for costs with respect to the first two phases, but it cannot currently estimate
the cost of any subsequent phases of work or final remediation which may be
required by the EPA.
 
    In 1989, Adobe received requests from the EPA for information pursuant to
Section 104(e) of CERCLA with respect to the D. L. Mud and Gulf Coast Vacuum
Services superfund sites located in Abbeville, Louisiana. The EPA has issued its
record of decision at the Gulf Coast Site and on February 9, 1993 the EPA issued
to all PRP's at the site a settlement order pursuant to Section 122 of CERCLA.
Earlier, an emergency order pursuant to Section 106 of CERLA was issued on
December 11, 1992, for purposes of containment due to the Louisiana rainy
season. On December 15, 1993 the Company entered into a sharing agreement with
other PRP'S to participate in the final remediation of the Gulf Coast site. The
Company's share of the remediation is approximately $600,000 and includes its
proportionate share of those PRPs who do not have the financial resources to
provide their share of the work at the site. A former site owner has already
conducted remedial activities at the D. L. Mud Site under a state agency
agreement. The extent, if any, of any further necessary remedial activity at the
D. L. Mud Site has not been finally determined.
 
  EMPLOYMENT AGREEMENTS
 
    The Company has entered into employment agreements with certain key
employees. The initial term of each agreement expired on December 31, 1990 and,
on January 1, 1991 and beginning on each January 1 thereafter, is automatically
extended for one-year periods, unless by September 30 of any year the Company
gives notice that the agreement will not be extended. The term of the agreements
is automatically extended for 24 months following a change of control. The
consummation of the Merger constituted a change of control as defined in the
agreements.
 
    In the event that following a change of control employment is terminated for
reasons specified in the agreements, the employee would receive: (i) a lump sum
payment equal to two years' base salary; (ii) the maximum possible bonus under
the terms of the Company's incentive compensation plan;
 
                                       50
 
<PAGE>
                        SANTA FE ENERGY RESOURCES, INC.
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
(iii) a lapse of restrictions on any outstanding restricted stock grants and
full payout of any outstanding Phantom Units; (iv) cash payment for each
outstanding stock option equal to the amount by which the fair market value of
the common stock exceeds the exercise price of the option; and, (v) life,
disability and health benefits for a period of up to two years. In addition,
payments and benefits under certain employment agreements are subject to further
limitations based on certain provisions of the Internal Revenue Code.
 
  INTEREST RATE SWAPS
 
    Prior to the Merger, Adobe had entered into two interest rate swaps with a
bank with notional principal amounts of $15.0 mllion and $20.0 million. Under
the terms of the $20.0 million swap, which expires in April 1994, during any
quarterly period at the beginning of which a floating rate specified in the
agreement is less than 7.84%, the Company must pay the bank interest for such
period on the principal amount at the difference between the rates. Should the
floating rate be in excess of 7.84%, the bank must pay the Company interest for
such period on the principal amount at the difference between the rates. For the
period from the effective date of the Merger to December 31, 1992 the amount due
the bank in accordance with the terms of the $20.0 million swap totalled $0.6
million and the amount due the bank in 1993 totalled $0.9 million. For the
quarterly period which ends in April 1994, the amount due the bank is based on a
floating rate of 3.375%. The $15.0 million swap, which expired December 31,
1992, had terms similar to the $20.0 million swap and the amount due the bank
for the period subsequent to the Merger totaled $0.5 million.
 
  OPERATING LEASES
 
    The Company has noncancellable agreements with terms ranging from one to ten
years to lease office space and equipment. Minimum rental payments due under the
terms of these agreements are: 1994 -- $6.1 million, 1995 -- $6.0 million,
1996 -- $5.5 million, 1997 -- $5.2 million, 1998 -- $4.4 million and $4.7
million thereafter. Rental payments made under the terms of noncancellable
agreements totaled $4.0 million in 1991,$4.5 million in 1992 and $5.5 million in
1993.
 
  OTHER MATTERS
 
    The Company has several long-term contracts ranging up to fifteen years for
the supply and transportation of approximately 30 million cubic feet per day of
natural gas. In the aggregate, these contracts involve a minimum commitment on
the part of the Company of approximately $10 million per year.
 
    There are other claims and actions, including certain other environmental
matters, pending against the Company. In the opinion of management, the amounts,
if any, which may be awarded in connection with any of these claims and actions
could be significant to the results of operations of any period but would not be
material to the Company's consolidated financial position.
 
(13)  INCOME TAXES
 
    Effective January 1, 1993 the Company adopted the provisions of Statement of
Financial Accounting Standards No. 109 -- 'Accounting for Income Taxes'. The
adoption of SFAS No. 109 had no significant impact on the Company's provision
for income taxes.
 
    Through the date of the Spin-Off the taxable income or loss of the Company
was included in the consolidated federal income tax return filed by SFP. The
Company has filed separate consolidated federal income tax returns for periods
subsequent to the Spin-Off. The consolidated federal income tax returns of SFP
have been examined through 1988 and all years prior to 1981 are closed. Issues
relating to the years 1981 through 1985 are being contested through various
stages of administrative appeal. The Company is evaluating its position with
respect to issues raised in a 1986 through 1988

audit. The Company believes adequate provision has been made for any adjustments
which might be assessed for all open years.
 
    During 1989, the Company received a notice of deficiency for certain state
franchise tax returns filed for the years 1978 through 1983 as part of the
consolidated tax returns of SFP. The years subsequent to 1983 are still subject
to audit. At December 31, 1993 Other Long-Term Obligations includes $20.6
million with respect to this matter. The Company intends to contest this matter.
 
    With the Merger of Adobe the Company succeeded to a net operating loss
carryforward that is subject to Internal Revenue Code Section 382 limitations
which annually limit taxable income that can be offset by such losses. Certain
changes in the Company's shareholders may impose additional limitations as well.
Losses carrying forward of $133.3 million expire beginning in 1998.
 
    At date of the Merger, Adobe had ongoing tax litigation related to a refund
claim for carryback of certain net operating losses denied by the Internal
Revenue Service. During 1991 Adobe successfully defended its claim in Federal
District Court and prevailed again in 1992 in the United States Court of Appeals
for the Fifth Circuit. The Internal Revenue Service had no further recourse to
litigation and a $16.2 million refund was reflected as Income Tax Refund
Receivable at December 31, 1992 and collected in 1993.
 
    Pretax income from continuing operations for the years ended December 31,
1993, 1992 and 1991 was taxed under the following jurisdictions:
 
                                           1993       1992       1991

</TABLE> 
    The fair value of the Trust Units and convertible preferred stock is based
on market prices. The fair value of the Company's fixed-rate long-term debt is
based on current borrowing rates available for financings with similar terms and
maturities. With respect to the Company's floating-rate debt, the carrying
amount approximates fair value. The fair value of the interest rate swap
represents the estimated cost to the Company over the remaining life of the
contract.
 
    At December 31, 1993 the Company had two open natural gas hedging contracts
and options outstanding on five additional contracts (see Note 12 -- Commitments
and Contingencies -- Natural Gas Hedging Contracts). Based on the settlement
prices of certain natural gas futures contracts as quoted on the New York
Mercantile Exchange on December 30, 1993, assuming all options are exercised,
the cost to the Company with respect to such contracts during 1994 would be
approximately $0.6 million.

</TABLE>
    Proved reserves are estimated quantities of crude oil and natural gas which
geological and engineering data indicate with reasonable certainty to be
recoverable in future years from known reservoirs under existing economic and
operating conditions. Proved developed reserves are proved reserves which can be
expected to be recovered through existing wells with existing equipment and
operating methods.
 
    Indonesian reserves represent an entitlement to gross reserves in accordance
with a production sharing contract. These reserves include estimated quantities
allocable to the Company for recovery of operating costs as well as quantities
related to the Company's net equity share after recovery of costs. Accordingly,
these quantities are subject to fluctuations with an inverse relationship to the
price of oil. If oil prices increase, the reserve quantities attributable to the
recovery of operating costs decline. Although this reduction would be offset
partially by an increase in the net equity share, the overall effect would be a
reduction of reserves attributable to the Company. At December 31, 1993, the
quantities include 0.6 million barrels which the Company is contractually
obligated to sell for $.20 per barrel.
 
    At December 31, 1993 the Company's reserves were 6.9 million barrels of
crude oil and liquids and 14.5 Bcf of natural gas lower than at December 31,
1992, reflecting the sale in 1993 of properties with reserves totalling 8.7
million barrels of crude oil and liquids and 47.4 Bcf of natural gas.
 
    At December 31, 1993, 1.9 million barrels of crude oil reserves and 19.7
billion cubic feet of natural gas reserves were subject to a 90% net profits
interest held by Santa Fe Energy Trust.

</TABLE> 
    Estimated future cash flows represent an estimate of future net cash flows
from the production of proved reserves using estimated sales prices and
estimates of the production costs, ad valorem and production taxes, and future
development costs necessary to produce such reserves. No deduction has been made
for depletion, depreciation or any indirect costs such as general corporate
overhead or interest expense.
 
    The sales prices used in the calculation of estimated future net cash flows
are based on the prices in effect at year end. Such prices have been held
constant except for known and determinable escalations.
 
    Operating costs and ad valorem and production taxes are estimated based on
current costs with respect to producing oil and gas properties. Future
development costs are based on the best estimate of such costs assuming current
economic and operating conditions.
 
    Income tax expense is computed based on applying the appropriate statutory
tax rate to the excess of future cash inflows less future production and
development costs over the current tax basis of the properties involved. While
applicable investment tax credits and other permanent differences are considered
in computing taxes, no recognition is given to tax benefits applicable to future
exploration costs or the activities of the Company that are unrelated to oil and
gas producing activities.
 
    The information presented with respect to estimated future net revenues and
cash flows and the present value thereof is not intended to represent the fair
value of oil and gas reserves. Actual future sales prices and production and
development costs may vary significantly from those in effect at year-end and
actual future production may not occur in the periods or amounts projected. This
information is presented to allow a reasonable comparison of reserve values
prepared using standardized measurement criteria and should be used only for
that purpose.

                    AGREEMENT AND SECOND AMENDMENT
                TO REVOLVING AND TERM CREDIT AGREEMENT

     THIS AGREEMENT AND SECOND AMENDMENT TO REVOLVING AND TERM CREDIT
AGREEMENT, hereinafter referred to as this "AMENDMENT", dated as of
April 14, 1993, is made and entered into by and among SANTA FE ENERGY
RESOURCES, INC. (the "COMPANY"), a Delaware corporation; each of the
lenders which is a signatory hereto (individually a "BANK" and
collectively the "BANKS"); TEXAS COMMERCE BANK NATIONAL ASSOCIATION
("TCB"), a national banking association, as Administrative Agent for
the Banks (in such capacity, together with its successors in such
capacity, the "AGENT"); and TCB and NATIONSBANK OF TEXAS, N.A.
("NATIONSBANK"), a national banking association, as Co-Agents (in such
capacity, the "CO-AGENTS").

RECITALS:

     1.  The Company, the Agent, the Co-Agents and the Banks have
entered into a Revolving and Term Credit Agreement dated as of May 20,
1992 (which Revolving and Term Credit Agreement, as amended to the
date hereof, is herein called the "CREDIT AGREEMENT").

     2.  The parties hereto desire to amend the Credit Agreement in
certain respects to provide, among other things, that the Company,
subject to certain terms and conditions, may reborrow any amounts
prepaid on the unpaid principal balance of the Term Loans at the
option of the Company, all as is more fully provided hereinbelow.

AGREEMENTS:

     NOW, THEREFORE, in consideration of the premises and the mutual
agreements, representations and warranties herein set forth, and for
other good and valuable consideration, the receipt and sufficiency of
which are acknowledged, the parties hereto do hereby agree as follows: 

     SECTION 1.  DEFINITIONS DELETED. The Credit Agreement is hereby
amended by deleting in its entirety the definition of "Term Loan
Principal Installment" contained in Section 1.1 of the Credit
Agreement.

     SECTION 2.  DEFINITIONS AMENDED.

         (a) The definition of "Applicable Margin" contained in
Section 1.1 of the Credit Agreement is hereby amended by deleting the
following parenthetical phrase each place that it appears therein: 

     (assuming the Available Amount is fully drawn for determinations
     related to the Independent Engineering Report and on the basis of
     the actual aggregate amount of
<PAGE>
     outstanding Revolving Loans and Letter of Credit Liabilities for
     all other determinations)

and substituting therefor the following in each such place:

     (assuming the Available Amount is fully drawn and that the
     aggregate unpaid principal balance of the Term Notes is equal to
     the Term Loan Maximum Amount for determinations related to the
     Independent Engineering Report and on the basis of the actual
     aggregate amount of outstanding Revolving Loans, Term Loans and
     Letter of Credit Liabilities for all other determinations)

         (b) The definition of "Interest Period" contained in Section
1.1 of the Credit Agreement is hereby amended by deleting the phrase
"due date of the final Term Loan Principal Installment" where it

as of May 19, 1993, is by and among SANTA FE ENERGY RESOURCES, INC.
(the "COMPANY"), a Delaware corporation; each of the lenders which is

the "CO- AGENTS").

     The parties agree as follows:

     Section 1.     DEFINITIONS AND ACCOUNTING MATTERS.

     1.1  CERTAIN DEFINED TERMS.  As used herein, the following terms
shall have the following meanings: 

     "ADDITIONAL COSTS" shall have the meaning ascribed to such term
in SECTION 6.1.

     "ADOBE" shall mean Adobe Resources Corporation, a Delaware
corporation.

     "ADOBE PROPERTIES" shall mean oil, gas and mineral properties and
other assets owned by Adobe at the time of the Merger.      

     "AFFILIATE" shall mean, as to any Person, any other Person which
directly or indirectly controls, or is under common control with, or
is controlled by, such Person; and with respect to an individual,
"AFFILIATE" shall also mean any individual related to such individual
by blood or marriage.  As used in this definition, "CONTROLS",
"CONTROLLED BY" and "UNDER COMMON CONTROL WITH" shall mean possession,
directly or indirectly, of power to direct or cause the direction of
management or policies (whether through ownership of securities or
partnership or other ownership interests, by contract or otherwise). 

     "ALTERNATE ANNUAL DEBT SERVICE COVERAGE RATIO" shall mean, as of
any date of determination and for the Calculation Period in which such
date occurs and for each Calculation Period thereafter to and
including the Calculation Period including the Termination Date, the
lowest of the ratios obtained by dividing (a) Combined CFADS 
(calculated on the basis of the Most Recent Engineering Report) for
such Calculation Period by (b) Alternate Debt Service of the Company
and the Restricted Subsidiaries for such Calculation  

<PAGE>

Period PLUS, at all times and to the extent the Special Subsidiary
Qualifying conditions are met, the Special Subsidiary Percentage times
the Alternate Debt Service of the Special Subsidiary for such
Calculation Period (in each case calculated on the basis set forth in
the most recent Coverage Report delivered to the Agent pursuant to
SECTION 9.1 and taking into account any incurrence or prepayment of
Covered Debt by the Company or any of the Restricted Subsidiaries or
the Special Subsidiary since the date of such Coverage Report).

     "ALTERNATE BASE RATE" shall mean, for any date, a rate per annum
(rounded upwards, if necessary, to the next higher 1/100%) equal to
the greater of (a) the Prime Rate in effect on such day or (b) the Fed

Alternate Base Rate due to a change in the Fed Funds Rate shall be
effective on the effective date of such change in the Fed Funds Rate. 
If for any reason the Agent shall have determined (which determination
shall be conclusive absent manifest error) that it is unable to
ascertain the Fed Funds Rate for any reason, including the inability
or failure of the Agent to obtain sufficient bids or publications in
accordance with the terms hereof, the Alternate Base Rate shall be the
Prime Rate until the circumstances giving rise to such inability no
longer exist.

     "ALTERNATE DEBT SERVICE" shall mean, for any Calculation Period
and with respect to any Person, the total of principal payments in
respect of Covered Debt of such Person and the total of interest
payments (using, with respect to interest to accrue, the interest
rates set forth in the most recent Approved Assumptions for such
Covered Debt not bearing interest at a fixed rate; if some or all of
such Covered Debt bears interest at one or more fixed rates as of the
date of determination of Alternate Debt Service but such Covered Debt
will not bear interest at such fixed rate or rates to the end of such
Calculation Period, then interest payments in respect of Alternate
Debt Service with respect to such Covered Debt shall be calculated on
the basis of such fixed rate or rates for such time as the same shall
be applicable to such Covered Debt, and then at the interest rates set
forth in the most recent Approved Assumptions) in respect of Covered
Debt of such Person, in each case paid and scheduled to be paid during
such Calculation Period; PROVIDED that the principal amount of any
Covered Debt of such Person which by its terms matures on a date
within such Calculation Period but which may reasonably be expected to
be reborrowed in a Rollover on such date shall not be deemed, for
purposes of this definition, to be scheduled to be paid on such date;
and PROVIDED FURTHER that for purposes of this definition it shall be
assumed that (a) surety bonds for environmental purposes and letters
of credit issued for the account of a Person will be fully drawn upon 
their respective expiry dates, (b) the reimbursement obligations of a
Person with respect to all surety bonds for environmental purposes and
letters of credit issued for
                                  -2-

its account shall be satisfied immediately and considered as a
"principal payment" for purposes of this definition. 

     "ANNUAL DEBT SERVICE COVERAGE RATIO" shall mean, as of any date
of determination and for the Calculation Period in which such date
occurs and for each Calculation Period thereafter to and including the
Calculation Period including the Termination Date, the lowest of the
ratios obtained by dividing (a) Combined CFADS (calculated on the
basis of the Most Recent Engineering Report) for such Calculation
Period by (b) Debt Service of the Company and the Restricted
Subsidiaries for such Calculation Period PLUS, at all times and to the
extent the Special Subsidiary Qualifying Conditions are met, the
Special Subsidiary Percentage times the Debt Service of the Special
Subsidiary for such Calculation Period (in each case calculated on the
basis set forth in the most recent Coverage Report delivered to the
Agent pursuant to SECTION 9.1 and taking into account any incurrence
or prepayment of Covered Debt by the  Company and the Restricted 
Subsidiaries and the Special Subsidiary since the date of such
Coverage Report).

     "APPLICABLE ENVIRONMENTAL LAWS" shall mean all applicable
environmental or pollution-control Legal Requirements governing,
without limitation, wastewater effluent, solid and hazardous waste or
substances and air emissions, together with any other applicable
requirements for conducting, on a timely basis, reporting, record
keeping, periodic tests and monitoring for contamination of ground
water, surface water, air and land and for biological toxicity of the
aforesaid, including, without  limitation, the Resource Conservation

     Section 2.     COMMITMENTS.

     2.1  LETTERS OF CREDIT. (a) COMMITMENTS.  Subject to the terms
and conditions of this Agreement, the Agent agrees, upon receipt by
Agent of an Application therefor, to issue, and each Bank severally
agrees to purchase from the Agent a participation in (according to
such Bank's Commitment Percentage), letters of credit containing such
provisions not inconsistent with the terms of this Agreement as the
Company may reasonably request and such provisions

                                 -27-
<PAGE>

not inconsistent with the terms of this Agreement as the Banks may
reasonably require (together with the Existing Letters of Credit, the
"LETTERS OF CREDIT") for the account of the Company and on behalf of
the Company, or for the joint and several account of and on behalf of
the Company and one or more of its Subsidiaries, as follows. From time
to time on or after the conditions herein set forth to issue such
Letters of Credit have been satisfied, and prior to the Termination
Date, the Agent shall issue and/or may have outstanding Letters of
Credit under this SECTION 2.1 in an aggregate principal amount at any
one time outstanding (including all Letter of Credit Liabilities at
such time) up to but not exceeding the lesser of (1) $15,000,000 (as
adjusted downward from time to time in accordance herewith) or (2) the
Available Amount less the aggregate unpaid principal balance of the
Revolving Notes; PROVIDED, that the aggregate Letter of Credit
Liabilities at any one time outstanding together with the aggregate
principal amount of Revolving Loans at any time outstanding shall
never exceed the Available Amount and PROVIDED, that anything to the
contrary in this Agreement notwithstanding, the Agent shall have no
obligation to issue any Letter of Credit on or after the Termination
Date. Upon the date of the issuance of a Letter of Credit on or after
the date hereof, the Agent shall be deemed, without further action by
any party hereto, to have sold to each Bank, and each Bank shall be
deemed, without further action by any party hereto, to have purchased
from the Agent, a participation, to the extent of such Bank's
Commitment Percentage, in such Letter of Credit and the related Letter
of Credit Liabilities. No Letter of Credit issued pursuant to this
Agreement shall have an expiry date later than one year from date of
issuance. Each Bank has heretofore purchased participations in each of
the Existing Letters of Credit and the related Letter of Credit
Liabilities, to the extent of such Bank's Commitment Percentage. Such
participations are hereby ratified and confirmed and made subject
hereto. All provisions of this Agreement applicable to participations
in Letters of Credit hereunder shall be deemed to apply to
participations in the Existing Letters of Credit.

     (b)  ADDITIONAL PROVISIONS. The following additional provisions
shall apply to each Letter of Credit:

     (i)  The Company shall give the Agent and each other Bank at
least five Business Days' irrevocable prior notice (effective upon
receipt) specifying the date such Letter of Credit is to be issued and
describing the proposed terms of such Letter of Credit and the nature
of the transaction proposed to be supported thereby. The Company shall
furnish such additional information regarding such transaction as the
Agent may reasonably request. Upon receipt of such notice, the Agent
shall promptly notify each Bank of such Bank's Commitment Percentage
of the amount of the proposed Letter of Credit and not later than two
Business Days prior to the requested issuance date for such Letter of
Credit shall furnish to each Bank and the Company a proposed form of
an Application for
                                 -28-
<PAGE>

such Letter of Credit. The issuance by the Agent of each Letter of
Credit shall, in addition to the conditions precedent set forth in
SECTION 7, be subject to the conditions precedent that such Letter of
Credit shall be in such form and contain such terms as shall be
reasonably satisfactory to the Agent and that the Company shall have
executed and delivered to the Agent an Application and such other
instruments and agreements relating to such Letter of Credit not
inconsistent with terms of this Agreement as the Agent shall have
reasonably requested and are not inconsistent with the terms of this
Agreement.

     (ii) No Letter of Credit may be issued if after giving effect
thereto the sum of (a) the aggregate outstanding principal amount of
the Revolving Loans plus (b) the aggregate Letter of Credit
Liabilities would exceed the Available Amount. On each day during the
period commencing with the issuance of any Letter of Credit and until
such Letter of Credit shall have expired or been terminated, the
Revolving Commitment of each Bank shall be deemed to be utilized for
all purposes hereof in an amount equal to such Bank's Commitment
Percentage of the amount then or thereafter available for drawings
under such Letter of Credit.

     (iii)  In consideration of the issuance of each Letter of Credit
the Company agrees to pay to the Agent, for the ratable benefit of the
Banks, the Letter of Credit Fee. The Letter of Credit Fee shall be
payable concurrently with the issuance of each such Letter of Credit
and shall be separate from and in addition to interest on any
Reimbursement Obligation. The Agent will pay to each Bank, promptly
after receiving any payment in respect of Letter of Credit Fees, an
amount equal to such Bank's Commitment Percentage of such Letter of
Credit Fees.

     (iv)  Upon receipt from the beneficiary of any Letter of Credit
of any demand for payment thereunder, the Agent shall promptly notify
the Company and each Bank as to the amount to be paid as a result of
such demand and the payment date. If at any time the Agent shall have
made a payment to a beneficiary of a Letter of Credit in respect of a
drawing or in respect of an acceptance created in connection with a
drawing under such Letter of Credit, each Bank will pay to the Agent
immediately upon demand (or, if such demand is made after 1:00 p.m.,
on the next succeeding Business Day) by the Agent at any time during
the period commencing after such payment until reimbursement thereof
in full by the Company, an amount equal to such Bank's Commitment
Percentage of such payment, together with interest on such amount for
each day from the later of (x) the date such payment is due as
provided in the preceding sentence or (y) the date such payment is
made under such Letter of Credit to the date of payment by such Bank
of such amount at a rate of interest per annum equal to the Fed Funds
Rate for such period. No interest shall be due from any Bank that
makes full payment to the Agent on the date such payment is due.
Nothing herein shall be deemed to require any Bank to pay to the Agent
any
                                 -29-
<PAGE>

amount as reimbursement for any payment made by the Agent to acquire
(discount) for its own account prior to maturity thereof any
acceptance created under a Letter of Credit.

     (v)  The Company shall be irrevocably and unconditionally
obligated forthwith to reimburse the Agent for the account of each
Bank for any amount paid by the Agent or such Bank upon any drawing
under any Letter of Credit, without presentment, demand, protest or
other formalities of any kind all of which are hereby expressly waived
by the Company. Each drawing under any Letter of Credit shall bear
interest at the Post-Default Rate until the Company shall have made
reimbursement for such drawing. If the Company shall fail to make
reimbursement for any such drawing prior to noon on the second
Business Day after such notice is given, the Agent may in its
discretion and without the consent of (but with concurrent notice to)
the Company effect such reimbursement of any Letter of Credit, subject
to the satisfaction of the conditions in SECTION 7 of the Revolving
and Term Credit Agreement and to the existence of Revolving
Commitments, by borrowing of Revolving Loans and the application of
the proceeds thereof to the related Reimbursement Obligations.  The
Reimbursement Obligations shall survive the Termination Date and the
termination of this Agreement. The Agent will pay to each Bank such
Bank's Commitment Percentage of all amounts received from the Company
for application in payment, in whole or in part, of the Reimbursement
Obligation in respect of any Letter of Credit, but only to the extent
such Bank has made payment to the Agent in respect of such Letter of
Credit pursuant to CLAUSE (iv) above. Nothing herein shall be deemed to
require the Agent to pay to any Bank any part of the proceeds of
disposition (rediscount) by the Agent for its own account to any other
Person of any acceptance created under a Letter of Credit which is
acquired (discounted) by the Agent prior to the maturity thereof or to
require any Bank to reimburse the Agent for the consequences of the
Agent's own gross negligence or willful misconduct.

     (vi) The obligations of the Company to pay Reimbursement
Obligations under this Agreement shall be absolute, unconditional and
irrevocable and shall be paid or performed strictly in accordance with
the terms of this Agreement under all circumstances whatsoever, 
including, without limitation, the following circumstances:

          (a)  any lack of legality, validity, regularity or
enforceability of this Agreement, any Letter of Credit, any
Application or any agreement or document related to any of the
foregoing;

          (b)  any amendment or waiver of (including any default), or
any consent to departure from, any Letter of Credit, this Agreement,
any Application or any agreement or document related to any of the
foregoing;
                                 -30-
<PAGE>
          (c)  the existence of any claim, set-off, defense or other
rights which the Company may have at any time against any beneficiary
or any transferee of any Letter of Credit (or any Persons or entities
for which such beneficiary or any such transferee may be acting), the
Agent, any Bank or any other Person, whether in connection with this
Agreement, any Letter of Credit, any Application or any agreement or
document related to any of the foregoing, the transactions
contemplated hereby or any unrelated transaction;

          (d)  any statement, certificate, draft or any other document
presented under any Letter of Credit proves to have been forged,
fraudulent, invalid or insufficient in any respect or any statement
therein proves to have been untrue or inaccurate in any respect
whatsoever;

          (e)  payment by the Agent under any Letter of Credit against
presentation of a draft or certificate which appears on its face to
comply but does not in fact comply with the terms of such Letter of
Credit;

          (f)  any defense based upon the failure of any beneficiary
or any transferee to receive all or any part of the proceeds of a draw
under any Letter of Credit transmitted by the Agent, or any
non-application or misapplication by any beneficiary or other
transferee of the proceeds of demand for payment under any Letter of
Credit; and

          (g)  any bankruptcy, insolvency, reorganization,
arrangement, assignment for the benefit of creditors, readjustment of
debt, dissolution, liquidation or other similar event with respect to
the Company.

PROVIDED, that no such payment shall impair any claim the Company may
have against the Agent or any Bank.

     (c)  ILLEGALITY. In the event that any restriction or limitation
is imposed upon or determined or held to be applicable to the Agent,
any Bank or the Company by, under or pursuant to any Legal
Requirement, which in the reasonable judgment of the Agent or any Bank
would prevent the Agent or such Bank from legally incurring liability
under or in respect of a Letter of Credit issued or proposed to be
issued hereunder, then the Agent shall give prompt written notice
thereof to the Company, whereupon the Agent and the Bank or Banks
affected shall have no obligation to issue or purchase participations
in any such Letter of Credit.

     2.2  AVAILABLE AMOUNT

          (a)  Concurrently with the delivery of each Independent
Engineering Report and related Coverage Report required or permitted
hereby, there shall be determined, based on the Most

                                 -31-
<PAGE>

Recent Engineering Report and Approved Assumptions, the total maximum
amount of Revolving Loans and Letters of Credit to be available to the
Company hereunder without violation of the Required Ratios. Upon each
such delivery, the Company may by notice to the Co-Agents designate as
the Available Amount any amount (not to exceed $50,000,000) equal to
or less than such total maximum amount. The Available Amount so
designated shall remain in effect as the Available Amount until the
next determination under this SECTION 2.2. If no different amount is
designated in accordance with this SECTION 2.2, the Available Amount
shall be the lesser of (a) the Preliminary Available Amount then in
effect or (b) such total maximum amount.

          (b)  Notwithstanding anything herein to the contrary, (1) no
Bank shall be required to have aggregate Letters of Credit Liabilities
at any one time outstanding in excess of such Bank's Commitment
Percentage of the lesser of (x) $15,000,000 and (y) the difference
between (i) the Available Amount and (ii) the aggregate Revolving
Loans, and (2) if a Bank fails to participate in a Letter of Credit as
and when required hereunder and the Company subsequently makes a
repayment on the Reimbursement Obligations with respect to such Letter
of Credit, such repayment shall be split among the non-defaulting
Banks ratably in accordance with their respective Commitment
Percentages until each Bank has its Commitment Percentage of all of
the outstanding Reimbursement Obligations, and the balance of such
repayment shall be divided among all of the Banks in accordance with
their respective Commitment Percentages.

          (c)  Notwithstanding anything in this Agreement to the
contrary, the Agent shall not be required to issue any Letter of
Credit during the existence of an Engineering Shortfall.

          (d)  The Company may from time to time at its option,
exercisable by giving written notice to the Co-Agents not more often
than once in any Calculation Period, provide to the Co-Agents an
Independent Engineering Report.  Upon the receipt of such notice, the
Co-Agents shall consult with the Company to determine new Approved
Assumptions, which shall be furnished to the Banks by a notice as
provided in the definition of "Approved Assumptions" and shall be
subject to the proviso therein. The Optional Reserve Report shall be
based on the new Approved Assumptions and shall be accompanied by a
Coverage Report as of the date such Report is furnished. The Annual
Debt Service Coverage Ratio, the Alternate Annual Debt Service
Coverage Ratio and the Life-of-Reserves Coverage Ratio shall each be
redetermined in accordance with this Agreement on the basis of each
such Optional Reserve Report and Coverage Report, and the Available
Amount recalculated as provided in this SECTION 2.2.

                                 -32-

          (e)  Notwithstanding any other provision of this Agreement
to the contrary, should both (x) the Company at any time designate as
the Available Amount an amount less than the maximum amount then
offered to it as the Available Amount by the Co-Agents and (y) as a
result the Company shall obtain the release of any Mortgaged
Properties under the Revolving and Term Credit Agreement, the
Available Amount may never thereafter exceed the amount so designated
by the Company.

     2.3  REDUCTIONS AND CHANGES OF COMMITMENTS.

     (a)  MANDATORY. On the Termination Date the aggregate Commitments
shall be terminated in their entirety.

     (b)  THE COMPANY'S OPTION. The Company shall have the right to
terminate or reduce the unused portion of the Commitments at any time
or from time to time; PROVIDED that: (i) the Company shall give notice
of each such termination or reduction to the Agent as provided in
SECTION 5.5; (ii) each such partial reduction shall be in minimum
increments equal to $5,000,000; and (iii) the Company may not cause
the Available Amount to be less than the aggregate principal amount of
the Revolving Loans then outstanding plus the Letter of Credit
Liabilities then outstanding. Any voluntary reduction in the Available
Amount prior to any scheduled reduction in the Available Amount shall
not affect the Available Amount after such scheduled reduction date
unless such voluntarily reduced Available Amount is less than the
amount scheduled to be the Available Amount after such scheduled
reduction date, in which case the Available Amount after such
scheduled reduction date shall be no greater than such voluntarily
reduced Available Amount.

     2.4  SEVERAL OBLIGATIONS. The failure of any Bank to participate
in any Letter of Credit shall not relieve any other Bank of its
obligation to participate in any Letter of Credit (the face amount of
which shall be reduced dollar for dollar by the amount of the share of
the Bank that failed to participate in such Letter of Credit) on such
date, but neither the Agent nor any Bank shall be responsible for the
failure of any other Bank to participate in any Letter of Credit.

     2.5  FEES. In consideration of the Commitments, the Company shall
pay to the Agent for the account of each Bank in accordance with its
Commitment Percentage commitment fees (the "COMMITMENT FEES") for the
period from the date of the execution of this Agreement to and
including the earlier of the date the Commitments are terminated or
the Termination Date at a rate per annum equal to 1/2% of the Unused
Commitment. The Company shall be entitled to credit on the Commitment
Fees any amount paid pursuant to SECTION 2.3 of the Revolving and Term
Credit Agreement. The Commitment Fees shall be computed for each day
and shall be based on the Unused Commitment for such day. Accrued
Commitment Fees shall be payable in arrears on the date of the initial
Letter of
                                 -33-
<PAGE>

Credit, within three days after demand therefor on or about the
Quarterly Dates, and within three days after demand therefor on or
about the Termination Date. All past due Commitment Fees shall bear
interest at the Post-Default Rate. Upon receipt, the Agent shall
disburse the Commitment Fees to the Banks in accordance with their
Commitment Percentages.

     Section 3.     PREPAYMENTS.

     3.1  (a)  COMMITMENT AMOUNT.  The Company shall from time to time
on demand by the Agent prepay the Revolving Loans or reduce Letter of
Credit Liabilities in such amounts as shall be necessary so that at
all times the aggregate outstanding principal amount of all Revolving
Loans and all Letter of Credit Liabilities hereunder shall not be in
excess of the aggregate of the Revolving Commitments and the
Commitments. Any such payment shall be allocated between Revolving
Loans, Letter of Credit Liabilities (and if to Letter of Credit
Liabilities, first, to Reimbursement Obligations) and other
obligations as the Company may elect.

     (b) AVAILABLE AMOUNT. The Company shall from time to time on
demand by the Agent and on the Termination Date prepay the Revolving
Loans or reduce Letter of Credit Liabilities in such amounts as shall
be necessary so that at all times the aggregate outstanding principal
amount of all Revolving Loans and all Letter of Credit Liabilities of
the Company hereunder shall be less than or equal to the Available
Amount. Any such payment shall be allocated between Revolving Loans,
Letter of Credit Liabilities (and if to Letter of Credit Liabilities,
first, to Reimbursement Obligations) and other obligations as the
Company may elect.

     Section 4.     PAYMENTS OF PRINCIPAL AND INTEREST.

     4.1  REPAYMENT OF REIMBURSEMENT OBLIGATIONS. The Company will pay
to the Agent for the account of each Bank the amount of each
Reimbursement Obligation forthwith upon its incurrence. The amount of
any Reimbursement Obligation may, if the applicable conditions
precedent specified in SECTION 7 of the Revolving and Term Credit
Agreement have been satisfied, be paid with the proceeds of Revolving
Loans.

     4.2  INTEREST.  Subject to SECTION 12.8, the Company will pay to
the Agent for the account of each Bank interest on the unpaid
principal amount of each Reimbursement Obligation owed to such Bank
for the period commencing on the date such Reimbursement Obligation
arises to but excluding the date such Reimbursement Obligation shall
be paid in full, at the Post-Default Rate.

     Accrued interest shall be due and payable from time to time on
demand of the Agent or the Required Banks (through the Agent).

                                 -34-
<PAGE>

     Section 5. PAYMENTS; PRO RATA TREATMENT; COMPUTATIONS, ETC.

     5.1  PAYMENTS. (a) Except to the extent otherwise provided
herein, all payments of principal of or interest on the Reimbursement
Obligations and other amounts to be made by the Company hereunder
shall be made in dollars, in immediately available funds, to the Agent
at its Principal Office (or in the case of a Successor Agent, at the
principal office of such successor Agent in the United States), not
later than 11:00 a.m. on the date on which such payment Shall become
due (each such payment made after such time on such due date to be
deemed to have been made on the next succeeding Business Day).

     (b) The Company shall, at the time of making each payment
hereunder, specify to the Agent the Reimbursement Obligations or other
amounts payable by the Company hereunder to which such payment is to
be applied (and in the event that it fails so to specify, such payment
shall be applied as the Agent may designate to the amounts then due
and payable); PROVIDED that if no Reimbursement Obligations are then
due and payable or an Event of Default has occurred and is continuing,
the Agent may apply such payment to the Obligations in such order as
it may elect in its sole discretion, but subject to the other terms
and conditions of this Agreement, including SECTION 5.2). Each payment
received by the Agent hereunder for the account of a Bank shall be
paid promptly to such Bank, in immediately available funds for the
account of such Bank's Applicable Lending Office.

     (c) If the due date of any payment hereunder falls on a day which
is not a Business Day, the due date for such payment shall be extended
to the next succeeding Business Day and interest shall be payable for
any principal so extended for the period of such extension.

     5.2  PRO RATA TREATMENT.  Except to the extent otherwise provided
herein, (a) each issuance of a Letter of Credit and each termination
or reduction of the Commitments of the Banks under SECTION 2.3 shall
be made PRO RATA according to the Banks' respective Commitments;
(b) each payment by the Company of principal of or interest on any
Reimbursement Obligation shall be made to the Agent for the account of
the Banks PRO RATA in accordance with the respective unpaid principal
amounts of such Reimbursement Obligation held by the Banks; and (c)
the Banks (other than the Agent) shall purchase from the Agent
participations in the Letters of Credit in accordance with their
respective Commitment Percentages.

     5.3  COMPUTATIONS. Interest based on the Alternate Base Rate (to
the extent determined by reference to the Prime Rate), and fees
hereunder, will be computed on the basis of 365 (or 366) days and
actual days elapsed (including the first day but excluding the last
day) occurring in the period for which payable. All other interest

                                 -35-

<PAGE>

shall be computed on the basis of a year of 360 days and actual days
elapsed (including the first day but excluding the last day) occurring
in the period for which payable, unless the effect of so computing
shall be to cause the rate of interest to exceed the Highest Lawful
Rate (in which event interest shall be calculated on the basis of the
actual number of days elapsed in a year composed of 365 or 366 days,
as the case may be).

     5.4 MINIMUM AND MAXIMUM AMOUNTS. Each Letter of Credit shall be
in a face amount at least equal to $100,000.

     5.5 CERTAIN ACTIONS, NOTICES, ETC. Notices to the Agent of any
termination or reduction of Commitments, prepayments under SECTION 3.1
and requests for the issuance of Letters of Credit shall be
irrevocable and shall be effective only if received by the Agent not
later than 11:00 a.m. on the number of Business Days prior to the date
of the relevant issuance, termination, reduction, and/or prepayment
specified below:
                              Number of Business
                                  Days Prior
                                    Notice
Termination or reduction
of Commitments                        10

Issuance of Letters of Credit          5

Prepayments                            1


Each such notice of termination or reduction shall specify the amount
of the Commitments to be terminated or reduced. Each such notice of
prepayment shall specify the amount to be prepaid (subject to SECTION
3.1) and the date of prepayment (which shall be a Business Day). The
Agent shall promptly notify the Banks of the contents of each such
notice or Application.  Notice of any prepayment having been given,
the principal amount specified in such notice, together with interest
thereon to the date of prepayment, shall be due and payable on such
prepayment date.

     5.6  NON-RECEIPT OF FUNDS BY THE AGENT.  Unless the Agent shall
have been notified by a Bank prior to noon on the date on which such
Bank is to make payment to the Agent of any amount to be paid by such
Bank to reimburse the Agent for a drawing under any Letter of Credit
or by the Company prior to the date on which the Company is to make a
payment to the Agent for the account of one or more of the Banks, as
the case may be (such Bank or the Company being herein called the
"PAYOR" and such payment being herein called the "REQUIRED PAYMENT"),
which notice shall be effective upon receipt, that the Payor does not
intend to make the Required Payment to the Agent, the Agent may assume
that the Required Payment has been made and may, in reliance upon such
assumption
                                 -36-
<PAGE>

(but shall not be required to), make the amount thereof available to
the intended recipient on the date that such Required Payment is to be
made. If the Payor is the Company and the Company has not in fact made
the Required Payment to the Agent on or before such date, the
recipient of such payment (or, if the recipient is the beneficiary of
a Letter of Credit, the Company, and, if the Company fails to pay the
amount thereof to the Agent on demand, then the Banks, to the extent
not already paid, ratably in proportion to their respective Commitment
Percentages) shall, on demand, pay to the Agent the amount made
available by the Agent, together with interest thereon from the date
such amount was so made available by the Agent until the date the
Agent recovers such amount at a rate per annum equal to the Fed Funds
Rate for the first three days and thereafter at the Fed Funds Rate
plus 2%. If the Payor is a Bank and such Bank has not in fact made the
Required Payment to the Agent on or before such date, then such Bank
shall pay to the Agent the amount made available by the Agent on
behalf of such Bank, together with interest thereon from the date such
amount was so made available by the Agent until the Agent recovers
such amount at a rate per annum equal to the Fed Funds Rate for the
first three days and thereafter at the Fed Funds Rate plus 2%.

     5.7 SHARING OF PAYMENTS, ETC. If a Bank or any participant of a
Bank shall obtain payment of any obligation to it under this
Agreement, through the exercise of any right of set-off, banker's
lien, counterclaim or similar right, or otherwise, then such Bank or
participant shall promptly purchase from the other Banks
participations in the Reimbursement Obligations or other obligations
held by the other Banks in such amounts, and make such other
adjustments from time to time as shall be equitable to the end that
all the Banks and participants shall share the benefit of such payment
(net of any expenses which may be incurred by such Bank or its
participant in obtaining or preserving such benefit) PRO RATA in
accordance with the unpaid principal and interest on such obligations
then due to each of them. To such end all the Banks and their
participants shall make appropriate adjustments among themselves (by
the resale of participations sold or otherwise) if such payment is
rescinded or must otherwise be restored.  The Company agrees, to the
fullest extent it may effectively do so under applicable law, that any
Bank so purchasing a participation in the Reimbursement Obligations or
other obligations held by other Banks may exercise all rights of
set-off, bankers' lien, counterclaims or similar rights with respect
to such participation as fully as if such Bank were a direct holder of
Reimbursement Obligations or other obligations in the amount of such
participation. Nothing contained herein shall require any Bank to
exercise any such right or shall affect the right of any Bank to
exercise, and retain the benefits of exercising, any such right with
respect to any other indebtedness or obligation of the Company.

     5.8  OTHER EXPENSES. The Company agrees to pay the Agent, for the
account of the Agent, the usual and customary charges of TCB for each
extension, amendment and wire advice of and drawing under the Letters
of Credit.

     Section 6.  YIELD PROTECTION AND ILLEGALITY.

     6.1  ADDITIONAL COSTS IN RESPECT OF LETTERS OF CREDIT. If as a
result of any Regulatory Change there shall be imposed, modified or
deemed applicable any tax, reserve, special deposit or similar
requirement against or with respect to or measured by reference to
Letters of Credit issued or to be issued hereunder and the result
shall be to increase the cost to the Agent or any Bank of issuing or
maintaining or participating in any Letter Of Credit or reduce any
amount receivable by the Agent or any Bank hereunder in respect of any
Letter of Credit or participation therein, then such Bank shall notify
the Company through the Agent, and upon demand therefor by such Bank
through the Agent, the Company (subject to SECTION 12.8) shall pay to
the Agent or such Bank, from time to time as specified by the Agent or
such Bank, such additional amounts as shall be sufficient to
compensate the Agent or such Bank for such increased costs or
reductions in amount. Before making such demand pursuant to this
SECTION 6.1, the Agent or such Bank will designate a different
available Applicable Lending Office for the Letter of Credit or
participation or take such other action as the Company may request, if
such designation or action will avoid the need for, or reduce the
amount of, such compensation and will not, in the sole opinion of the
Agent or such Bank, be disadvantageous to the Agent or such Bank. A
statement as to such increased costs or reductions in amount incurred
by the Agent or such Bank, submitted by the Agent or such Bank to the
Company, shall cover amounts accruing under this section with respect
to a period beginning not earlier than 120 days from the date thereof
and be conclusive as to the amount thereof, absent manifest error.

     In the event any Bank shall seek compensation pursuant to this
SECTION 6.1, the Company may give notice to such Bank (with copies to
the Agent) that it wishes to seek one or more Eligible Assignees
(which may be one or more of the Banks) to assume the Commitment of
such Bank and to purchase and assume its outstanding Letter of Credit
Liabilities. Each Bank requesting compensation pursuant to this
SECTION 6.1 agrees to sell its Commitment and interest in this
Agreement and in the Obligations and in the Revolving and Term Credit
Agreement pursuant to SECTION 12.6 (without recourse, representation
or warranty except as provided in SECTION 12.6) to any such Eligible
Assignee for an amount equal to the sum of the outstanding unpaid
principal of and accrued interest on such Obligations plus all other
fees and amounts (including any compensation claimed by such Bank
under this SECTION 6.1) owing to such Bank hereunder and under the
Revolving and Term Credit Agreement calculated, in each case, to the
date such Commitment, Obligations and interests are purchased,
whereupon such Bank shall

                                 -38-
<PAGE>

have no further Commitment or other obligation to the Company
hereunder or under the Revolving and Term Credit Agreement.

     6.2  CAPITAL ADEQUACY. If any Bank shall have determined that the
adoption after the date hereof or effectiveness after the date hereof
(regardless of whether previously announced) of any applicable Legal
Requirement or treaty regarding capital adequacy, or any change after
the date hereof in any existing or future Legal Requirement or treaty
regarding capital adequacy, or any change in the interpretation or
administration thereof after the date hereof by any Governmental
Authority or comparable agency charged with the interpretation or
administration thereof, or compliance by any Bank (or its Applicable
Lending Office) with any request or directive after the date hereof
regarding capital adequacy (whether or not having the force of law) of
any such Governmental Authority or comparable agency has or would have
the effect of reducing the rate of return on the capital of such Bank
(or any holding company of which such Bank is a part) as a consequence
of its obligations hereunder and under or in respect of the Letters of
Credit to a level below that which such Bank or holding company could
have achieved but for such adoption, change or compliance by an amount
deemed by such Bank to be material, then from time to time, upon
demand by such Bank (with a copy to the Agent), the Company (subject
to SECTION 12.8) shall pay to such Bank such additional amount or
amounts as will compensate such Bank or holding company for such
reduction. The certificate of any Bank setting forth such amount or
amounts as shall be necessary to compensate it and the basis therefor
shall cover amounts accruing under this SECTION 6.2 with respect to a
period beginning not earlier than 120 days from the date thereof and
shall be conclusive and binding, absent manifest error. The Company
shall pay the amount shown as due on any such certificate upon
delivery of such certificate.  In preparing such certificate, a Bank
may employ such assumptions and allocations of costs and expenses as
it shall in good faith deem reasonable and may use any reasonable
averaging and attribution method. In the event any Bank shall seek
compensation pursuant to this SECTION 6.2, the Company may give notice
to such Bank (with copies to the Agent) that it wishes to seek one or
more Eligible Assignees (which may be one or more of the Banks) to
assume the Commitment of such Bank and to purchase and assume its
outstanding Letter of Credit Liabilities. Each Bank requesting
compensation pursuant to this SECTION 6.2 agrees to sell its
Commitment and interest in this Agreement and in the Obligations and
in the Revolving and Term Credit Agreement pursuant to SECTION 12.6
(without recourse, representation or warranty except as provided in
SECTION 12.6) to any such Eligible Assignee for an amount equal to the
sum of the outstanding unpaid principal of and accrued interest on
such Obligations plus all other fees and amounts (including any
compensation claimed by such Bank under this SECTION 6.2) owing to
such Bank hereunder and under the Revolving and Term Credit Agreement
calculated, in each case, to the date such Commitment, Obligations,
and interests are purchased, whereupon such Bank shall

                                 -39-
<PAGE>

have no further Commitment or other obligation to the Company
hereunder or under the Revolving and Term Credit Agreement.

participate in Letters of Credit, the Company represents and warrants
(such representations and warranties to survive any investigation and
the issuance of Letters of Credit) to the Banks and the Agent as
follows:

     8.1  CORPORATE EXISTENCE. Each member of the Combined Group (a)
is duly organized, validly existing and in good standing under the
laws of the jurisdiction of its organization; (b) has all requisite
power, and has all licenses, permits, authorizations, consents and
approvals necessary, to own its property and carry on its business as
now being conducted, and (c) is qualified to do business, and is in
good standing, in (1) all jurisdictions in which any of the Recognized
Proved Reserves which it owns are located and (2) any other
jurisdiction in which the nature of the business conducted by it makes
such qualification necessary or advisable, unless (for purposes only
of this CLAUSE (2)) the failure to be so qualified or in good standing
would not individually or in the aggregate have a material adverse
effect on the business, financial condition or results of operations
of the Combined Group taken as a whole.

     8.2  INFORMATION.

     (a) (i) The most recent consolidated balance sheet of the Company
and its Subsidiaries and the related consolidated statements of
operations, changes in financial position and cash flows for the
period then ended, together with the respective notes thereto,
delivered to each of the Banks prior to the execution of this
Agreement (which financial statements are dated December 31, 1991) or
in accordance with the provisions of SECTION 9.1(a) or (b), as the
case may be (the latest of such financial statements and the notes
thereto being referred to herein as the "MOST RECENT FINANCIAL
STATEMENTS"), fairly present in all material respects the consolidated
financial position of the Company and its Subsidiaries as of such date
and their consolidated results of operations for the period then ended
in conformity with GAAP.

     (ii) The Company and its Subsidiaries did not on the date of the
Most Recent Financial Statements, and do not on the date as of which
this representation is made in accordance with the terms of this
Agreement, have any material contingent liabilities, material
liabilities for taxes, unusual and material forward or long-term
commitments or material unrealized or anticipated losses from any
commitments, except (A) as referred to or reflected or provided for in

     (b)  Since December 31, 1991, there has been no Material Adverse
Change.

     8.3  LITIGATION; COMPLIANCE.  Except as disclosed in the
Registration Statement, or as hereafter disclosed to the Banks in

or arbitral proceedings or any proceedings by or before any
Governmental Authority now pending, or, to the knowledge of the
Company, threatened, against or affecting the Company or any of its
Subsidiaries which, if adversely determined, would cause a Material
Adverse Change. The Company and its Subsidiaries comply in all
material respects with all applicable material (based on the Company
and its Subsidiaries taken as a whole) Legal Requirements other than
the Applicable Environmental Laws. Neither the Company nor any of its
Subsidiaries is in default in any material respect under or violation
of any material (based on the Company and its Subsidiaries taken as a
whole) judgment, order or decree of any Governmental Authority.

     8.4  NO BREACH.  None of the execution and delivery of the
Credit Documents, the consummation of the transactions therein
contemplated or compliance with the terms and provisions thereof will
conflict with or result in a breach of, or require any consent that
has not been obtained under, the Serial Note Agreement, the
Organizational Documents of the Company or any of its Subsidiaries or
any material Legal Requirement (including any securities law, rule or
regulation) applicable to the Company or any of its Subsidiaries or
(except for the Liens required or permitted by this Agreement) result
in the creation or imposition of any Lien upon any of the revenues or
property of the Company or any of its Subsidiaries. Such execution,
delivery, consummation and compliance do not and will not conflict
with or result in a breach of any material agreement or instrument to
which the Company is a party or by which the Company is bound or to
which it is subject, or constitute a default under any such agreement
or instrument.

     8.5  CORPORATE ACTION.  The Company has all necessary corporate
power and authority to execute, deliver and perform its obligations
under the Credit Documents. The execution, delivery and performance of
the Credit Documents by the Company have been duly authorized by all
necessary corporate action.  The Credit Documents have been duly and
validly executed and delivered by the Company and constitute the
legal, valid and binding obligations of the Company, enforceable in
accordance with their respective terms, except as the enforceability
thereof may be limited by bankruptcy, insolvency, fraudulent
conveyance, reorganization, moratorium or other similar laws relating
to the enforcement of creditors' rights generally and by general
equitable principles.

     8.6  APPROVALS.  All authorizations, approvals and consents of,
and all filings and registrations with, all Governmental Authorities
and each other Person necessary for the execution,       

                                 -43-

enforceability thereof, except for the filings and recordings of the
Liens created pursuant to the Security Documents under the Revolving
and Term Credit Agreement, have been obtained by the Company.

     8.7   REGULATIONS G, U AND X. Neither the Company nor any of its
Subsidiaries is engaged principally, or as one of its important
activities, in the business of extending credit for the purpose of
purchasing or carrying margin stock (within the meaning of Regulation
G, U or X of the Board) and no Letter of Credit hereunder will be used
to acquire or carry, directly or indirectly, any such margin stock.

     8.8  ERISA.  (a) The Company and each ERISA Affiliate have
fulfilled their contribution obligations under each Plan subject to
Title IV of ERISA and have fulfilled their obligations under the
minimum funding standards of ERISA and the Code with respect to each
Plan subject to Title IV of ERISA, and in all other regard with
respect to each Plan are in material compliance with the applicable
provisions of ERISA, the Code, and all other applicable laws,
regulations and rules, to the extent that noncompliance with such
provisions would result in a Material Adverse Change. (b) The Company
has no knowledge of any event with respect to each Plan which could
result in a Material Adverse Change.

     8.9  TAXES.  Each of the Company and its Subsidiaries has filed
all United States federal income tax returns and all other material
tax returns which are required to be filed by it and has paid all
taxes due pursuant to such returns or pursuant to any assessment
received by it, except to the extent the same may be contested in good
faith by appropriate proceedings diligently conducted for which
adequate reserves have been established in accordance with GAAP. The
charges, accruals and reserves on the books of the Company and its
Subsidiaries in respect of taxes and other governmental charges, as
made on a periodic basis, are adequate.

     8.10  SUBSIDIARIES. SCHEDULE I is a complete and correct list, as
of the date of this Agreement, of all Subsidiaries of the Company. All
shares or other indicia of equity interest of the Restricted
Subsidiaries and the Special Subsidiary directly or indirectly owned

validly issued, fully paid and non-assessable.

     8.11 INVESTMENT COMPANY ACT.  No member of the Combined Group is

     8.12 PUBLIC UTILITY HOLDING COMPANY ACT.  No member of the
Combined Group is a "public utility company", or, to the knowledge of

utility company", or a "holding company", or an "affiliate" or a
"subsidiary company" of a "holding company" or of a "subsidiary
company" of a "holding company", as such terms are defined in the

     8.13 ENVIRONMENTAL MATTERS.  Except as disclosed in the
Registration Statement, the Company and its Subsidiaries, and the
plants and sites of each, have complied with all Applicable
Environmental Laws, except, in any such case, where such failure to so
comply would not result in a Material Adverse Change. Without limiting
the generality of the preceding sentence, neither the Company nor any
of its Subsidiaries has received notice of or has actual knowledge of
any actual or claimed or asserted failure so to comply with Applicable
Environmental Laws or of any other Environmental Claim which alone or
together with all other such failures or Environmental Claims is
material and would result in a Material Adverse Change. Except as
disclosed in the Registration Statement, neither the Company nor any
of its Subsidiaries nor their plants or other sites manage, generate
or dispose of, or during their respective period of use, ownership,
occupancy or operation by the Company or its Subsidiaries have
managed, generated, released or disposed of, any hazardous wastes,
hazardous substances, hazardous materials, toxic substances or toxic
pollutants, as those terms are used or defined in the Applicable
Environmental Laws, in material violation of or in a manner which
would result in liability under the Applicable Environmental Laws or
any other applicable Legal Requirement, or in a manner which would
result in an Environmental Claim except where such noncompliance or
liability or Environmental Claim would not result in a Material
Adverse Change.  The representation and warranty contained in this
SECTION 8.13 is based in its entirety upon (a) current interpretations
and enforcement policies that have been publicly disseminated and are
used by Governmental Authorities charged with the enforcement of the
Applicable Environmental Laws or which apply to the Company or any of
its Subsidiaries with respect to any property or sites in a particular
jurisdiction and (b) current levels of publicly disseminated
scientific knowledge concerning the detection of, and the health and
environmental risks associated with the discharge of, substances and
pollutants regulated pursuant to the Applicable Environmental Laws.

otherwise dispose of all or substantially all of its assets subject to
the conditions and provisions specified in SECTIONS 9.7(c)(2) and (3);

      (4) any Restricted Subsidiary may merge into or consolidate with

Restricted Subsidiary;

      (5) any Restricted Subsidiary may permit any Person to be merged

or any state thereof and having at least 80% of its consolidated
assets located in the United States of America and Canada which
expressly assumes in writing the due and punctual performance of the
obligations of the Company under the Credit Documents, to the same
extent as if such successor or transferee corporation had originally
executed the Credit Documents in the place of the Company (it being
agreed that such assumption shall, upon the request of any Bank and at
the expense of such successor or transferee corporation, be evidenced
by the exchange of each outstanding Application for another
Application executed by such successor or transferee corporation, with
such changes in phraseology and form as may be appropriate but in
substance of like terms as the Application surrendered for such
exchange and of like unpaid principal amount, and that each
Application executed pursuant to this Agreement after such assumption
shall be executed by and in the name of such successor or transferee
corporation);

PROVIDED that for purposes of SECTIONS 9.7(e)(6) and (7) immediately
after such merger, consolidation, sale or other disposition, and after
giving effect thereto, (x) such successor or transferee Person could
incur at least $1.00 of additional Funded Debt without violation of

reasonable detail the
                                -60-
<PAGE>

proposed transaction, the date on which it is proposed to be
consummated and the identity, jurisdiction of organization, and
geographic composition of assets of the proposed successor or
transferee corporation.  No disposition by the Company of its assets
as an entirety or substantially as an entirety under SECTION 9.7(e)(7)
shall release the Company as the applicant under any Application from
its liability as obligor thereon.

application of any sales proceeds received in connection therewith,
Special Debt shall not exceed 10% of the Consolidated Net Tangible
Assets; or

      (2) the net sales proceeds received by the Company or a
Restricted Subsidiary in respect of the assets sold pursuant to such
Sale and Leaseback Transaction are greater than or equal to the fair
market value of the assets sold (which determination shall be based
upon a written opinion (the cost of which shall be borne exclusively
by the Company) as to valuation from an independent valuation expert
selected by the Company) and such proceeds are concurrently applied to
(A) the purchase, acquisition, development or construction of assets
having a value at least equal to such net proceeds, and to be used in
the Company's or such Restricted Subsidiary's business; PROVIDED that
no Liens shall at any time exist on such assets which secure any Debt
except as permitted by SECTION 9.7(a)(13); (B) the prepayment in
accordance with this Agreement of any aggregate principal amount of
all the Obligations (plus accrued interest and premium, if any) at
least equal to the amount of such net proceeds; or (C) the payment of
other Funded Debt (other than Funded Debt subordinate in right of
payment to the Obligations) in an aggregate principal amount at least
equal to the amount of such net sales proceeds; or

      (3) the Sale and Leaseback Transaction involves the sale of
assets by the Company to a wholly owned Restricted Subsidiary or by a
Restricted Subsidiary to the Company or to another wholly owned
Restricted Subsidiary; PROVIDED that if the Company is the seller
under any such Sale and Leaseback Transaction, its lease obligations
thereunder shall be subordinated to the Obligations represented by the
Applications upon terms set forth on SCHEDULE V.

    (g) INVESTMENTS IN THE SPECIAL SUBSIDIARY. Directly or indirectly
make an Investment in the Special Subsidiary after March 31, 1990,
unless (1) the aggregate amount of all other Investments in the
Special Subsidiary made, directly or indirectly, by the Company and
the Restricted Subsidiaries after March 31, 1990 shall not exceed the
aggregate amount of cash distributions received by the Company and the
Restricted Subsidiaries from the Special Subsidiary after March 31,
1990 or (2) in the opinion of

                                -61-
<PAGE>

the Board of Directors of the Company, the Investment would not impair
the ability of the Company to make when due any payment (including any
prepayment required by SECTION 3 of principal of or interest on the
Reimbursement Obligations.

    (h) TRANSACTIONS WITH AFFILIATES.  Directly or indirectly
purchase, acquire or lease any property from, or sell, transfer or
lease any property to, or otherwise deal with, in the ordinary course
of business or otherwise, (1) any Affiliate (except any employee
compensation benefit plan or any Restricted Subsidiary) or (2) any
Person (other than a Restricted Subsidiary) in which an Affiliate or
the Company (directly or indirectly)  owns, beneficially or of record,
5% or more of the outstanding voting stock or similar equity interest,
except that (A) any Affiliate may be a director, officer or employee
of the Company or any Restricted Subsidiary and may be paid reasonable
compensation in connection therewith and (B) subject to applicable
fiduciary standards with respect to the Special Subsidiary, acts and
transactions that would otherwise be prohibited by this Subsection may
be performed or engaged in if upon terms not less favorable to the
Company or any Restricted Subsidiary than if no relationship described
in CLAUSES (1) and (2) above existed.

    (i)  TAX CONSOLIDATION.  Except for the Tax Allocation Agreements,
the Company will not, and will not permit any of its Subsidiaries to,
file or consent to the filing of any consolidated income tax return
with any Person unless such other Person shall have agreed in writing
with the Company that the Company's or such Subsidiary's liability
with respect to taxes as a result of the filing of any such
consolidated income tax return with such Person shall not be
materially greater, nor the receipt of any tax benefits materially
less, than they would have been had the Company and its Subsidiaries
continued to file a consolidated income tax return with the Company as
the parent corporation.

    9.8  ISSUANCE OF STOCK BY RESTRICTED SUBSIDIARIES. The Company
covenants that it will not permit any Restricted Subsidiary (either
directly or indirectly, by the issuance of rights or options for, or
securities convertible into, such shares) to issue, sell or otherwise
dispose of any shares of any authorized but unissued or treasury class
of such Restricted Subsidiary's stock (other than directors'
qualifying shares) except to the Company or another Restricted
Subsidiary.

    9.9  COVERAGE RATIOS.  As of the end of each fiscal quarter of the
Company, and each delivery of a Required Reserve Report or Optional
Reserve Report, the Company shall be in compliance with all Required
Ratios (except for any noncompliance resulting solely from an
Engineering Shortfall, and then only during the cure period permitted
by Section 10.1(e)).

    Section 11.     THE AGENT.

    11.1  APPOINTMENT, POWERS AND IMMUNITIES.  Each Bank hereby
irrevocably appoints and authorizes the Agent to act as its Agent
under the Credit Documents and under the Letters of Credit with such
powers as are specifically delegated to the Agent by the terms
thereof, together with such other powers as are reasonably incidental
thereto. The Agent (which term as used in this SECTION 11 shall
include reference to its Affiliates and its own and its Affiliates'
officers, directors, employees and agents) shall (a) have no duties or
responsibilities except those expressly set forth in the Letters of
Credit and the Credit Documents, and shall not by reason of any Credit
Document be a trustee or fiduciary for any Bank; (b) not be
responsible to any Bank for any recitals, statements, representations
or warranties contained in any Credit Document, or in any certificate
or other document referred to or provided for in, or received by any
of them under, any Credit Document, or for the value, validity,
effectiveness, genuineness, enforceability or sufficiency of any
Credit Document or any other document referred to or provided for
therein or any property covered thereby or for any failure by the
Company or any other Person to perform any of its obligations
thereunder; (c) not be required to initiate or conduct any litigation
or collection proceedings hereunder or under any Credit Document
except to the extent requested by the Required Banks (and SECTION 11.7
shall apply), and (d) not be responsible for any action taken or
omitted to be taken by it under any Credit Document or any other
document or instrument referred to or provided for therein or in
connection therewith, including pursuant to its own negligence, except
for its own gross negligence or willful misconduct. The Agent may
employ agents and attorneys-in-fact and shall not be responsible for
the negligence or misconduct of any such agents or attorneys-in-fact
selected by it with reasonable care. Without in any way limiting any
of the foregoing, each Bank acknowledges that the Agent shall have no
greater responsibility in the operation of the Letters of Credit than
is specified in the Uniform Customs and Practice of Documentary
Credits (1983 Revision, International Chamber of Commerce Publication
No. 400).

    11.2  RELIANCE BY AGENT.  The Agent shall be entitled to rely upon
any certification, notice or other communication (including any
thereof by telephone, telex, telegram or cable) believed by it to be
genuine and correct and to have been signed or sent by or on behalf of
the proper Person or Persons, and upon advice and statements of legal
counsel (which may be counsel for the Company), independent
accountants and other experts selected by the Agent. As to any matters
not expressly provided for by any Credit Document, the Agent shall in
all cases be fully protected in acting, or in refraining from acting,
hereunder and thereunder in accordance with instructions of the
Required Banks, and any action taken or failure to act pursuant
thereto shall be binding on all of the Banks.

                                -67-
<PAGE>
     11.3  DEFAULTS.  The Agent shall not be deemed to have knowledge
of the occurrence of a Default (other than the non-payment of
principal of or interest on Reimbursement Obligations) unless it has
received notice from a Bank or the Company specifying such Default and
stating that such notice is a "Notice of Default". In the event that
the Agent receives such a notice of the occurrence of a Default, the
Agent shall give prompt notice thereof to the Banks (and shall give
each Bank prompt notice of each such non-payment). The Agent shall
(subject to SECTIONS 11.7 and 12.5) take such action with respect to
such Default as shall be directed by all Banks or the Required Banks,
as appropriate, and within its rights under the Credit Documents and
at law or in equity; PROVIDED that, unless and until the Agent shall
have received such directions, the Agent may (but shall not be
obligated to) take such action, or refrain from taking such action,
permitted hereby with respect to such Default as it shall deem
advisable in the best interests of the Banks and within its rights
under the Credit Documents, at law or in equity.
    
    11.4  RIGHTS AS A BANK.  With respect to their Commitments, the
Letters of Credit and the Reimbursement Obligations, TCB and
NationsBank in their capacities as Banks hereunder shall have the same
rights and powers hereunder as any other Bank and may exercise the
same as though they were not acting as the Agent or the Co-Agents, and
the term "Bank" or "Banks" shall, unless the context otherwise
indicates, include the Agent and the Co-Agents in their individual
capacity.  The Agent and the Co-Agents may (without having to account
therefor to any Bank) accept deposits from, lend money to and
generally engage in any kind of banking, trust, letter of credit,
agency or other business with the Company (and any of its Affiliates)
as if they were not acting as the Agent and the Co-Agents, and the
Agent and the Co-Agents may accept fees and other consideration from
the Company and its Affiliates (in addition to the fees heretofore
agreed to between the Company and the Agent or the Co-Agents) for
services in connection with this Agreement or otherwise without having
to account for the same to the Banks.

    11.5  INDEMNIFICATION.  The Banks agree to indemnify the Agent (to
the extent not reimbursed under SECTION 12.3 or 12.4, but without
limiting the obligations of the Company under said SECTIONS 12.3 and
12.4), ratably in accordance with their respective Commitments, for
any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any
kind and nature whatsoever (including the consequences of the
negligence of the Agent) which may be imposed on, incurred by or
asserted against the Agent in any way relating to or arising out of
any Credit Document or any other documents contemplated by or referred
to therein or the transactions contemplated thereby (including the
costs and expenses which the Company is obligated to pay under
SECTIONS 12.3 and 12.4 but excluding, unless a Default has occurred
and is continuing, normal administrative costs and expenses incident
to the performance of

                                 -68-
<PAGE>

its agency duties hereunder) or the enforcement of any of the terms
hereof or thereof or of any such other documents, including the
negligence of the Agent; PROVIDED that no Bank shall be liable for any
of the foregoing to the extent they arise from the gross negligence or
willful misconduct of the party to be indemnified. The obligations of
the Banks under this SECTION 11.5 shall survive the termination of
this Agreement.

    11.6  NON-RELIANCE ON THE AGENT AND OTHER BANKS.  Each Bank agrees
that it has received current financial information with respect to the
Company and that it has, independently and without reliance on the
Co-Agents or any other Bank and based on such documents and
information as it has deemed appropriate, made its own credit analysis
of the Company and decision to enter into this Agreement and that it
will, independently and without reliance upon the Co-Agents or any
other Bank, and based on such documents and information as it shall
deem appropriate at the time, continue to make its own analysis and
decisions in taking or not taking action under the Credit Documents.
The Co-Agents shall not be required to keep themselves informed as to
the performance or observance by the Company of any Credit Document or
any other document referred to or provided for therein or to inspect
the property or books of the Company or any other Person. Except for
notices, reports and other documents and information expressly
required to be furnished to the Banks by the Co-Agents under the
Credit Documents, the Co-Agents shall not have any duty or
responsibility to provide any Bank with any credit or other
information concerning the affairs, financial condition or business of
the Company (or any of its Affiliates) which may come into the
possession of the Co-Agents.
    
    11.7  FAILURE TO ACT.  Except for action expressly required of the
Agent under the Credit Documents, the Agent shall in all cases be
fully justified in failing or refusing to act hereunder and thereunder
unless it shall receive further assurances to its satisfaction by the
Banks of their indemnification obligations under SECTION 11.5 against
any and all liability and expense which may be incurred by it by
reason of taking or continuing to take any such action.

    11.8  RESIGNATION OR REMOVAL OF THE AGENT.  Subject to the
appointment and acceptance of a successor Agent as provided below, the
Agent may resign at any time by giving notice thereof to the Banks and
the Company, and the Agent may be removed at any time with or without
cause by the Required Banks.  Upon any such resignation or removal,
the Required Banks shall have the right to appoint a successor Agent.
If no successor Agent shall have been so appointed by the Required
Banks and shall have accepted such appointment within 30 days after
the retiring Agent's giving of notice of resignation or the Required
Banks' removal of the retiring Agent, then the retiring Agent may, on
behalf of the Banks, appoint a successor Agent. Any successor Agent
shall be a bank which has an office in the United States and a
combined

                                -69-
<PAGE>

capital and surplus of at least $250,000,000 and with its deposits
insured by the FDIC. Upon the acceptance of any appointment as the
Agent hereunder by a successor Agent, such successor Agent shall
thereupon succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Agent, and the retiring Agent
shall be discharged from its duties and obligations hereunder. Such
successor Agent shall promptly specify its Principal Office referred
to in SECTIONS 3.1 and 5.1 by notice to the Company. After any
retiring Agent's resignation or removal hereunder as the Agent, the
provisions of this SECTION 11 shall continue in effect for its benefit
in respect of any actions taken or omitted to be taken by it while it
was acting as the Agent.

    Section 12.  MISCELLANEOUS.

    2.1  WAIVER.  No waiver of any Default shall be a waiver of any
other Default. No failure on the part of the Agent or any Bank to
exercise and no delay in exercising, and no course of dealing with
respect to, any right, power or privilege under any Credit Document
shall operate as a waiver thereof, nor shall any single or partial
exercise of any right, power or privilege thereunder preclude any
other or further exercise thereof or the exercise of any other right,
power or privilege. The remedies provided in the Credit Documents are
cumulative and not exclusive of any remedies provided by law or in
equity.

   12.2  NOTICES.  All notices and other communications provided for
herein (including any modifications of, or waivers or consents under,
this Agreement) shall be given or made by telex, telegraph, telecopy
(confirmed by mail), cable or other writing and telexed, telecopied,

in respect of any Credit Document or any other document referred to

    12.4  INDEMNIFICATION.  The Company shall indemnify the Agent
(including the Agent when acting as issuer of the Letters of Credit),
the Co-Agents, the Banks, and each Affiliate thereof and their
respective directors, officers, employees, agents and counsel from,
and hold each of them harmless against, any and all losses,
liabilities, costs, expenses, claims or damages to which any of them
may become subject, regardless of and including losses arising from
the negligence of the Agent or the Co-Agents or the Banks or any other
indemnitee, (A) in connection with the execution and delivery or
transfer of or payment or failure to pay under any Letter of Credit,
including, without limitation, any claims, damages, losses,
liabilities, costs or expenses which the Agent, such Co-Agent or such
Bank, as the case may be, may incur (whether incurred as a result of
its own negligence or otherwise) by reason of or in connection with
the failure of any other Bank (whether as a result of its own
negligence or otherwise) to fulfill or comply with its obligations to
the Agent or such Bank, as the case may be, hereunder (but nothing
herein contained shall affect the rights the Company may have against
such defaulting Bank); and (B) insofar as such losses, liabilities,
costs, expenses, claims or damages arise out of or result from any (a)
actual or proposed use by the Company of the proceeds of any extension
of credit by the Agent or any Bank hereunder; (b) breach by the
Company of any Credit Document; (c) violation by the Company or any of
its Subsidiaries of any Legal Requirement including Applicable
Environmental Laws; (d) any Bank's or the Agent's or any Co-Agent's
being deemed an owner or operator of any assets of the Company or its
Subsidiaries by a court or other regulatory or administrative agency
or tribunal in circumstances in which neither the Agent, either
Co-Agent nor any of the Banks is generally operating or generally
exercising control over such assets, to the extent such losses,
liabilities, claims or damages arise out of or result from any Legal
Requirement including Applicable Environmental Laws pertaining to the
condition of such assets, (e) Environmental Claim or (f)
investigation, litigation or other proceeding (including any
threatened investigation or proceeding) relating to any of the
foregoing, and the Company shall reimburse the Agent, Co-Agent, each
Bank, and each Affiliate thereof and their respective directors,
officers, employees, agents and counsel, upon demand, for any expenses
(including reasonable legal fees) incurred in connection with any such
investigation or proceeding; but excluding any such losses,
liabilities, claims, damages, costs or expenses incurred by a Person
or any Affiliate thereof or their respective directors, officers,
employees, agents or counsel by reason of the gross negligence or
willful misconduct                                
                                 -71-
<PAGE>

of such Person, Affiliate director, officer, employee, agent or
counsel.  The obligation of the Company to provide indemnification
under this SECTION 12.4 for fees and expenses of counsel shall be
limited to the fees and expenses of one counsel in each jurisdiction
representing all of the Persons entitled to such indemnification,
except to the extent that, in the reasonable judgment of any such
indemnified Person, the existence of actual or potential conflicts of
interest make representation of all of such indemnified Persons by the
same counsel inappropriate; in such a case, the Person exercising such
judgment shall be indemnified for the reasonable fees and expenses of
its separate counsel to the extent provided in this SECTION 12.4
without giving effect to the first clause of this sentence.  Nothing
in this SECTION 12.4 is intended to limit the obligations of the
Company under any other provision of this Agreement.

    12.5  AMENDMENTS, ETC.  No amendment or waiver of any provision of
any Credit Document, nor any consent to any departure by the Company
therefrom, shall in any event be effective unless the same shall be
agreed or consented to by the Required Banks and the Company, and each
such waiver or consent shall be effective only in the specific
instance and for the specific purpose for which given; PROVIDED that
no amendment, waiver or consent shall, unless in writing and signed by
each Bank affected thereby, (a) increase the Commitment of any of the
Banks or subject the Banks to any additional obligations; (b) reduce
the principal of, or interest on, any Reimbursement Obligation, fee or
other sum to be paid under any Credit Document; (c) postpone any
scheduled date fixed for any payment of principal of, or interest on,
any Reimbursement Obligation, fee or other sum to be paid under any
Credit Document; (d) change the percentage of any of the Commitments,
or of the aggregate unpaid principal amount of the Reimbursement
Obligations, or the number of Banks which shall be required for the
Banks or any of them to take any action under this Agreement; (e)
change any provision contained in SECTIONS 2.3, 5.2, 5.7, 6, 12.3 or
12.4 or this SECTION 12.5, or in the definition of "Required Ratios".
Anything in this SECTION 12.5 to the contrary, no amendment, waiver or
consent shall be made with respect to SECTION 11 without the consent
of the Agent and the Co-Agents.

    12.6  SUCCESSORS AND ASSIGNS. (a) This Agreement shall be binding
upon and inure to the benefit of the Company, the Agent, the Co-Agents
and the Banks and their respective successors and assigns.  The
Company may not assign or transfer any of its rights or obligations
hereunder without the prior written consent of all of the Banks.

    (b) Each Bank may sell participations to any Person in all or part
of its Reimbursement Obligation, or all or part of its Commitment, in
which event, without limiting the foregoing, the provisions of SECTION
6 shall inure to the benefit of each purchaser of a participation and
the PRO RATA treatment of

                                -72-
<PAGE>

payments, as described in SECTION 5 2, shall be determined as if such
Bank had not sold such participation.  In the event any Bank shall
sell any participation, (1) the Company, the Agent, the Co-Agent and
the other Banks shall continue to deal solely and directly with such
selling Bank in connection with such selling Bank's rights and
obligations under the Credit Documents (including the Applications
held by such selling Bank); (2) such Bank shall retain the sole right
and responsibility to enforce the Reimbursement Obligations, including
the right to approve any amendment, modification or waiver of any
provision of this Agreement other than amendments, modifications or
waivers with respect to (A) any fees payable hereunder to the Banks,
and (B) the amount of principal or the rate of interest payable on, or
the dates fixed for the scheduled repayment of principal of, the
Reimbursement Obligations and other sums to be paid to the Banks
hereunder, and (3) the Company agrees, to the fullest extent it may
effectively do so under applicable law, that any participant of a Bank
may exercise all rights of set-off, bankers' lien, counterclaim or
similar rights with respect to such participation as fully as if such
participant were a direct holder of Reimbursement Obligations if such
Bank has previously given notice of such participation to the Company.

    (c) Each Bank may assign to one or more Banks or Eligible
Assignees all or a portion of its interests, rights and obligations
under this Agreement (including all or a portion of its Commitment and
the same portion of the related Reimbursement Obligations at the time
owing to it); PROVIDED (1) other than in the case of an assignment to
a Person at least 50% owned by the assignor Bank, or by a common
parent of both, or to another Bank, the Agent and the Company must
give their respective prior written consent, which consent will not be
unreasonably withheld; (2) the aggregate amount of the Commitment
and/or Reimbursement Obligations of the assigning Bank subject to each
such assignment (determined as of the date the Assignment Agreement
with respect to such assignment is delivered to the Agent) shall in no
event be less than $750,000 (or $75,000 in the case of an assignment
between Banks) (except for certain exceptions approved by the Company
and the Agent) and shall be in an amount that is an integral multiple
of $75,000; (3) the assigning Bank shall contemporaneously assign to
such assignee Bank or Eligible Assignee an equal percentage of the
assigning Bank's Revolving Commitment and Term Loan Commitment and all
assigning Bank's other rights and obligations under the Revolving and
Term Credit Agreement; and (4) the parties to each such assignment
shall execute and deliver to the Agent, for its acceptance and
recording in its records, an Assignment Agreement with blanks
appropriately completed, together with the Applications subject to
such assignment and a processing and recordation fee of $2,000 (for
which the Company shall have no liability except in the case of
assignments required by the Company pursuant to SECTION 6.1 or 6.2, in
which case such fee shall be paid by the Company). Upon such
execution, delivery, acceptance and recording, from and after the

                                -73-
<PAGE>

effective date specified in each Assignment Agreement, (A) the
assignee thereunder shall be a party hereto and, to the extent
provided in such Assignment Agreement, have the rights and obligations
of a Bank hereunder and (B) the Bank thereunder shall, to the extent
provided in such assignment, be released from its obligations under
this Agreement (and, in the case of an Assignment Agreement covering
all or the remaining portion of an assigning Bank's rights and
obligations under this Agreement, such Bank shall cease to be a party
hereto).

    (d) By executing and delivering an Assignment Agreement, the Bank
assignor thereunder and the assignee thereunder confirm to and agree
with each other and the other parties hereto as follows  (1) other
than the representation and warranty that it is the legal and
beneficial owner of the interest being assigned thereby, such assignor
Bank makes no representation or warranty and assumes no responsibility
with respect to any statements, warranties or representations made in
or in connection with any Credit Document or the execution, legality,
validity, enforceability, genuineness, sufficiency or value of any
Credit Document; (2) such assignor Bank makes no representation or
warranty and assumes no responsibility with respect to the financial
condition of the Company or the performance or observance by the
Company of any of its obligations under any Credit Document; (3) such
assignee confirms that it has received a copy of this Agreement,
together with copies of the financial statements of the Company
previously delivered in accordance herewith and such other documents
and information as it has deemed appropriate to make its own credit
analysis and decision to enter into such Assignment Agreement; (4)
such assignee will, independently and without reliance upon the Agent,
such assignor Bank or any other Bank and based on such documents and
information as it shall deem appropriate at the time, continue to make
its own credit decisions in taking or not taking action under the
Credit Documents; (5) such assignee appoints and authorizes the Agent
to take such action as agent on its behalf and to exercise such powers
under the Credit Documents as are delegated to the Agent by the terms
hereof, together with such powers as are reasonably incidental
thereto, and (6) such assignee agrees that it will perform in
accordance with their terms all obligations that by the terms of the
Credit Documents are required to be performed by it as a Bank.

    (e) The Agent shall maintain at its office a copy of each
Assignment Agreement delivered to it and a record of the names and
addresses of the Banks and the Commitment of, and principal amount of
the Reimbursement Obligations owing to, each Bank from time to time.
The entries in such record shall be conclusive, in the absence of
manifest error, and the Company, the Agent and the Banks say treat
each Person the name of which is recorded therein as a Bank hereunder
for all purposes of the Credit Documents. Such records shall be
available for inspection by the Company or any

                                -74-
<PAGE>

Bank at any reasonable time and from time to time upon reasonable
prior notice.

    (f) Upon its receipt of an Assignment Agreement executed by an
assigning Bank and the assignee thereunder together with the
Application subject to such assignment, the written consent to such
assignment and the fee payable in respect thereto, the Agent shall, if
such Assignment Agreement has been completed with blanks appropriately
filled, (1) accept such Assignment Agreement; (2) record the
information contained therein in its records, and (3) give prompt
notice thereof to the Company.

   (g) Any Bank may, in connection with any assignment or
participation or proposed assignment or participation pursuant to this
Section, disclose to the assignee or participant or proposed assignee
or participant, any information relating to the Company furnished to
such Bank by or on behalf of the Company.

   (h) Any assignment by a Bank pursuant to this SECTION 12.6 shall
not result in any single Bank holding in excess of 25% of the
aggregate of the Commitments at any one time.

   (i) Notwithstanding any other provision of this SECTION 12.6, TCB
and its Affiliates may not assign their rights hereunder unless, after
giving effect to such assignment, TCB and its Affiliates would have an
aggregate Commitment Percentage of at least 10%.

   (j) Notwithstanding anything herein to the contrary, each Bank may
pledge and assign all or any portion of its rights and interests under
the Credit Documents to any Federal Reserve Bank.

   12.7  SURVIVAL; TERM; REINSTATEMENT.  In addition to the other
provisions of this Agreement expressly stated to survive the
termination of this Agreement, the obligations of the Company under
SECTIONS 6, 12.3 and 12.4 and the last sentence of this SECTION 12.7
and the obligations of the Banks under SECTION 12.8 shall survive the
termination of this Agreement. The term of this Agreement shall be
until (a) the full and final payment of all Reimbursement Obligations,
(b) the expiry of all Letters of Credit, (c) the termination of all
Commitments and (d) the payment of all amounts due under the Credit
Documents. The Company agrees that if at any time all or any part of
any payment previously applied by any Bank to any Reimbursement
Obligation or other sum hereunder is or must be returned by or
recovered from such Bank for any reason (including the order of any
bankruptcy court), the Credit Documents shall automatically be
reinstated to the same effect as if the prior application had not been
made, and the Company hereby agrees to indemnify such Bank against,
and to save and hold such Bank harmless from, any required return by
or recovery from such Bank of any such payment because of its being
deemed preferential under applicable Legal Requirements, or for any
other reason.

                                -75-

     12.8  LIMITATION OF INTEREST.  The parties to this Agreement
intend to strictly comply with all applicable laws, including
applicable usury laws. Accordingly, the provisions of this Section
shall govern and control over every other provision of any Credit
Document which conflicts or is inconsistent with this Section, even if
such provision declares that it controls. As used in this SECTION
12.8, the term "interest" includes the aggregate of all charges, fees,
benefits or other compensation which constitute interest under
applicable law; PROVIDED that, to the maximum extent permitted by
applicable law, (a) any non-principal payment shall be characterized
as an expense or as compensation for something other than the use,
forbearance or detention of money, and not as interest and (b) all
interest at any time contracted for, reserved, charged or received
shall be amortized, prorated, allocated and spread, in equal parts
during the full term of this Agreement and the Commitments. In no
event shall the Company or any other Person be obligated to pay, or
the Agent or any Bank have any right or privilege to reserve, receive
or retain, (x) any interest in excess of the maximum amount of
nonusurious interest permitted under the laws of the State of Texas or
the applicable laws (if any) of the United States or of any other
state or (y) total interest in excess of the amount which the Agent or
such Bank could lawfully have contracted for, reserved, received,
retained or charged had the interest been calculated for the full term
of this Agreement at the Highest Lawful Rate.  On each day, if any,
that the interest rate (the "Stated Rate") called for under any Credit
Document exceeds the Highest Lawful Rate, the rate at which interest
shall accrue shall automatically be fixed by operation of this
sentence at the Highest Lawful Rate for that day, and shall remain
fixed at the Highest Lawful Rate for each day thereafter until the
total amount of interest accrued equals the total amount of interest
which would have accrued if there were no such ceiling rate as is
imposed by this sentence. Thereafter, interest shall accrue at the
Stated Rate unless and until the Stated Rate again exceeds the Highest
Lawful Rate when the provisions of the immediately preceding sentence
shall again automatically operate to limit the interest accrual rate.
The daily interest rates to be used in calculating interest at the
Highest Lawful Rate shall be determined by dividing the applicable
Highest Lawful Rate per annum by the number of days in the calendar
year for which such calculation is being made. None of the terms and
provisions contained in any Credit Document which directly or
indirectly relate to interest shall ever be construed without
reference to this Section, or be construed to create a contract to pay
for the use, forbearance or detention of money at an interest rate in
excess of the Highest Lawful Rate. If the term of this Agreement is
shortened by reason of acceleration of maturity as a result of any
Default or by any other cause, or by reason of any required or
permitted prepayment, and if for that (or any other) reason the Agent
or any Bank at any time, including the stated maturity, is owed or
receives (and/or has received) interest in excess of interest
calculated at the Highest Lawful Rate, then and in any such event all
of any such excess interest shall be

                                -76-
<PAGE>

canceled automatically as of the date of such acceleration, prepayment
or other event which produces the excess, and, if such excess interest
has been paid to the Agent or such Bank, it shall be credited PRO
TANTO against the then-outstanding principal balance of the Company's
obligations to the Agent or such Bank, effective as of the date or
dates when the event occurs which causes it to be excess interest,
until such excess is exhausted or all of such principal has been fully
paid and satisfied, whichever occurs first, and any remaining balance
of such excess shall be promptly refunded to its payor.

   12.9  CAPTIONS.  Captions and section headings appearing herein are
included solely for convenience of reference and are not intended to
affect the interpretation of any provision of this Agreement.

   12.10  COUNTERPARTS.  Each Credit Document may be executed in any
number of counterparts, all of which taken together shall constitute
one and the same agreement and any of the parties hereto may execute
such Credit Document by signing any such counterpart.

   12.11  GOVERNING LAW.  Except to the extent otherwise specified
therein, each Credit Document shall be governed by and construed in
accordance with the law of the State of Texas and the United States of
America. The Company hereby submits to the nonexclusive jurisdiction
of the United States District Court for the Southern District of Texas
and of any Texas state court sitting in Harris County, Texas for
purposes of all legal proceedings arising out of or relating to the
Credit Documents or the transactions contemplated thereby The Company
irrevocably waives, to the fullest extent permitted by law, any
objection which it may now or hereafter have to the laying of the
venue of any such proceeding brought in such a court and any claim
that any such proceeding brought in such a court has been brought in
an inconvenient forum.

   12.12  SEVERABILITY.  Whenever possible, each provision of the
Credit Documents shall be interpreted in such manner as to be
effective and valid under applicable law. If any provision of any
Credit Document shall be invalid, illegal or unenforceable in any
respect under any applicable law, the validity, legality and
enforceability of the remaining provisions of such Credit Document
shall not be affected or impaired thereby.

   12.13  CHAPTER 15 NOT APPLICABLE.  Chapter 15 of the Texas Credit
Code shall not apply to any Credit Document or to any Commitment or
Letter of Credit or Application or Reimbursement Obligation, nor shall
any Credit Document be governed by or be subject to the provisions of
such Chapter 15 in any manner whatsoever.

                                -77-

     IN WITNESS WHEREOF, the parties hereto have caused this Agreement
to be duly executed and delivered on May 20, 1992 but effective as of

the provisions of subsection (h) below, bear interest, payable on
demand, for each day until paid at a rate per annum equal to the sum
of 1% plus the Prime Rate for such day.

          (b)  Each CD Loan shall, subject to the provisions of
subsection (h) below, bear interest on the outstanding principal
amount thereof, for the Interest Period applicable thereto, at a rate
per annum equal to the applicable Fixed CD Rate; PROVIDED that if any
CD Loan or any portion thereof shall, as a result of clause (2)(b)(i)
of the definition of Interest Period, have an Interest Period of less
than 30 days, such portion shall bear interest during such Interest
Period at the rate applicable to Prime Loans during such period. Such
interest shall be payable for each Interest Period on the last day
thereof and, if such Interest Period is longer than 90 days, at
intervals of 90 days after the first day thereof. Any overdue
principal of and, to the extent permitted by law, overdue interest on
any CD Loan shall, subject to the provisions of subsection (h) below,
bear interest, payable on demand, for each day until paid at a rate
per annum equal to the sum of 1% plus the higher of (i) the Fixed CD
Rate applicable to such Loan and (ii) the Prime Rate for such day.

          The "Fixed CD Rate" applicable to any CD Loan for any
Interest Period means a rate per annum equal to the sum of 5/8 of 1%
plus the applicable Adjusted CD Rate.

          The "Adjusted CD Rate" applicable to any Interest Period
means a rate per annum determined pursuant to the following formula:

                                 -23- 
<PAGE>

                   {    CDBR    } *
        ACDR   =   { ---------- } + AR
                   { 1.00 - DRP }

        ACDR   =   Adjusted CD Rate
        CDBR   =   CD Base Rate                    1931
         DRP   =   Domestic Reserve Percentage
          AR   =   Assessment Rate

       ______________
       *  The amount in brackets being rounded upwards, if
       necessary, to the next higher of 1/100 of 1%.

          The "CD Base Rate" applicable to any Interest Period is the
rate of interest determined by the Agent to be the arithmetic average
(rounded upward, if necessary, to the next higher 1/100 of 1%) of the
prevailing rates per annum bid at 10:00 A.M. (New York City time) (or
as soon thereafter as practicable) on the first day of such Interest
Period by two or more New York certificate of deposit dealers of
recognized standing for the purchase at face value from each CD
Reference Bank of its certificates of deposit in an amount comparable
to the unpaid principal amount of the CD Loan of such CD Reference
Bank to which such Interest Period applies and having a maturity
comparable to such Interest Period.

          "Domestic Reserve Percentage" means for any day that
percentage (expressed as a decimal) which is in effect on such day, as
prescribed by the Board of Governors of the Federal Reserve System (or
any successor) for determining the maximum reserve requirement
(including without limitation any basic, supplemental or emergency
reserves) for a member bank of the Federal Reserve System in New York
City with deposits exceeding five billion dollars in respect of new
non-personal time deposits in dollars in New York City having a
maturity comparable to the related Interest Period and in an amount of
$100,000 or more.  The Fixed CD Rate shall be adjusted automatically
on and as of the effective date of any change in the Domestic Reserve
Percentage.

          "Assessment Rate" means for any Interest Period the net
annual assessment rate (rounded upwards, if necessary, to the next
higher 1/100 of 1%) actually incurred by Morgan Guaranty Trust Company
of New York to the Federal Deposit Insurance Corporation (or any
successor) for such Corporation's (or such successor's) insuring time
deposits at offices of Morgan Guaranty Trust Company of New York in
the United States during the most recent period for which such
                                 -24-

rate has been determined prior to the commencement of such Interest
Period.

          (c)  Each Euro-Dollar Loan shall, subject to the provisions
of subsection (h) below, bear interest on the outstanding principal
amount thereof, for the Interest Period applicable thereto, at a rate
per annum equal to the sum of 1/2 of 1% plus the applicable London
Interbank Offered Rate. Such interest shall be payable for each
Interest Period on the last day thereof and, if such Interest Period
is longer than three months, at intervals of three months after the
first day thereof.

          The "London Interbank Offered Rate" applicable to any
Interest Period means the average (rounded upward, if necessary, to
the next higher 1/16 of 1%) of the respective rates per annum at which
deposits in dollars are offered to each of the Euro-Dollar Reference
Banks in the London inter-bank market at approximately 11:00 A.M.
(London time) two Euro-Dollar Business Days before the first day of
such Interest Period in an amount approximately equal to the principal
amount of the Euro-Dollar Loan of such Euro-Dollar Reference Bank to
which such Interest Period is to apply (or, if applicable, the
principal amount of the Loan to be made pursuant to Section 2.12) and
for a period of time comparable to such Interest Period.
                                       
          (d)  Any overdue principal of and, to the extent permitted
by law, overdue interest on any Euro-Dollar Loan shall, subject to the
provisions of subsection (h) below, bear interest, payable on demand,
for each day from and including the date payment thereof was due to
but excluding the date of actual payment, at a rate per annum equal to
the sum of 1 1/2% plus the average (rounded upward, if necessary, to
the next higher 1/16 of 1%) of the respective rates per annum at which
one day (or, if such amount due remains unpaid more than three Euro-
Dollar Business Days, then for such other period of time not longer
than six months as the Agent may elect) deposits in dollars in an
amount approximately equal to such overdue payment due to each of the
Euro-Dollar Reference Banks are offered to such Euro-Dollar Reference
Bank in the London interbank market for the applicable period
determined as provided above (or, if the circumstances described in
clause (a) or (b) of Section 8.01 shall exist, at a rate per annum
equal to the sum of 1% plus the rate applicable to Prime Loans for
such day).

          (e)  Each Tranche B Loan shall, subject to the provisions of
subsection (h) below, bear interest on the
                                 -25-
<PAGE>

outstanding principal amount thereof, for each day from the date such
Loan is made until it becomes due, at 9.63% per annum, except that any
Tranche B Loan made pursuant to Section 2.12 shall bear interest on
the outstanding principal amount thereof at the rate set forth on the
addendum hereto and in the Note relating to such Loan.  Any overdue
principal of, premium (if any) under Section 2.07 or 6.04, and, to the
extent permitted by law, overdue interest on any Tranche B Loan shall,
subject to the provisions of subsection (h) below, bear interest,
payable on demand, for each day until paid at a rate per annum equal
to the sum of 1% plus the rate specified in the previous sentence. 
Such interest shall be payable in arrears on each March 31, June 30,
September 30 and December 31, commencing September 30, 1987.

          (f)  The Agent shall determine each interest rate applicable
to the Tranche A Loans hereunder.  The Agent shall give prompt notice
to the Borrower and the Tranche A Lenders by telex or telecopy of each
rate of interest so determined, and its determination thereof shall be
conclusive in the absence of manifest error.

          (g)  Each Reference Bank agrees to use its best efforts to
furnish quotations to the Agent as contemplated hereby.  If any
Reference Bank does not furnish a timely quotation, the Agent shall
determine the relevant interest rate on the basis of the quotation or
quotations furnished by the remaining Reference Bank or Banks or, if
none of such quotations is available on a timely basis, the provisions
of Section 8.01 shall apply.

          (h)  Notwithstanding the foregoing provisions, the
APPLICABLE RATE OF INTEREST per annum on each Loan outstanding shall
be, for each day, if the aggregate ownership by Santa Fe Southern
Pacific AND its WHOLLY-OWNED Subsidiaries of limited partnership
interests in Energy Partners, as a percentage of the total outstanding
limited partnership interests in Energy Partners, on such day is (i)
less than 50% but greater than or equal to 25%, increased by 1/8 of 1%
per annum, (ii) less than 25% but greater than or equal to 10%,
increased by 1/4 of 1% per annum, or (iii) LESS THAN 10%, INCREASED BY
1/2 OF 1% PER ANNUM.

          SECTION 2.06.  MANDATORY TERMINATION OR REDUCTION OF TRANCHE
A COMMITMENTS.  (a)  The Tranche A Commitments shall terminate on
December 31, 1997, and any Tranche A Loans then outstanding (together
with accrued interest thereon) shall be due and payable on such date.

                                 -26-
<PAGE>
          (b)  On any date after the date of the first Borrowing on
which the Commitment of any Tranche A Lender shall be greater than the
principal amount of the Loan of such Tranche A Lender outstanding on
such date (after giving effect to any repayment, prepayment and
borrowing on such date), the Commitment of such Lender shall be
automatically reduced to an amount equal to such outstanding principal
amount.

          (c)  The aggregate Tranche A Commitments shall be further
reduced (and the Commitment of each Tranche A Lender shall be
correspondingly reduced on a pro rata basis), on each Reduction Date
in each year as follows:

                                  REDUCTION ON EACH
        YEAR                       REDUCTION DATE

        1990                        $1,377,777.78

        1997                        $  688,888.88

PROVIDED that (i) any reduction of the Commitments pursuant to
subsection (b) shall reduce the amount of subsequent mandatory
reductions of Commitments pursuant to this subsection (c) as directed
by the Borrower in a notice (which shall be irrevocable once given) to
the Agent on or prior to the date of such reduction of the Commitments
pursuant to subsection (b); (ii) if any Tranche A Loan is made
pursuant to Section 2.12, the amount of each of the remaining
reductions of Commitments pursuant to this subsection (c) shall be
ratably increased in proportion to the increase in the aggregate
Tranche A Commitments hereunder; and (iii) the schedule of mandatory
reductions of Commitments pursuant to this subsection (c) may be
adjusted from time to time as contemplated by Section 5.08(a)

          (d)  On each Reduction Date, the Borrower shall repay such
principal amount (together with accrued interest thereon) of each
Tranche A Lender's outstanding Loan, if any, as may be necessary so
that after such repayment, the unpaid principal amount of such
Lender's Loan does not exceed the amount of such Lender's Commitment
as then reduced.

          SECTION 2.07.  PREPAYMENTS.  (a)  The Borrower may, subject
to the provisions of subsection (c) below, prepay any Prime Borrowing
in whole at any time, or from time to time in part.

          (b)  Except as provided in Section 8.02 the Borrower may not
prepay all or any portion of the principal amount of any Fixed Rate
Loan prior to the maturity thereof.

          (c) (i)  If (x) the Borrower determines to reduce the
aggregate principal amount of Loans outstanding hereunder and such
reduction is not called for by the provisions of Section 2.04(b) and
Section 2.06(c) and (d) (any such reduction herein referred to as a
"Prepayment"), or (y) the Borrower determines to increase, on a
prospective basis pursuant to Section 5.08(a), the amount of scheduled
reductions on a Reduction Date of the aggregate principal amount of
Loans outstanding hereunder called for by the provisions of Section
2.04(b) and Section 2.06(c) and (d) (any such increase in such
scheduled reduction for such Reduction Date herein referred to as a
"Prospective Prepayment"), then, it shall give the Agent notice (a
"Notice of Prepayment" or "Notice of Prospective Prepayment") of such
determination not less than 15 days prior to the date on which it
wishes to (i) make such Prepayment or (ii) adjust the amounts of the
installments to be due under Section 2.04(b) and the amounts of the
reductions in Commitments under Section 2.06(c) to give effect to such
Prospective Prepayment.  Such date shall, in the case of a Prepayment,
be a Domestic Business Day, and, if the Tranche A Loans then
outstanding are Fixed Rate Loans, the last day of the then current
Interest Period (other than an Interest Period provided for in clause
(l)(c)(i) or (2)(b)(i) of the definition of "Interest Period").  Each
Prepayment shall be of an amount equal to (x) $5,000,000 or a larger
multiple of $1,000,000, (y) such amount as will effect the restoration
of the Coverage Ratios to their required levels under Section 5.08, or
(z) the aggregate principal amount of Loans outstanding.  Each
Prospective Prepayment under this Section shall be in such amount as
will, when taken together with other related adjustments being made to
the scheduled reductions of Loans outstanding hereunder, restore the
Annual Coverage Ratio to its required level under Section 5.08(a). 
Each Notice of Prepayment and Notice of Prospective Prepayment shall
specify how the amount of such Prepayment or Prospective Prepayment is
to be allocated, on an aggregate basis for both Tranche A and Tranche
B Loans, to the remaining scheduled reductions in the Loans under
Section 2.04(b) and Section 2.06(c) and (d).

                                 -28-

             (ii) Unless the aggregate amount of all prior Prepayments
and Prospective Prepayments as to which notice has been given under
this Section exceeds $20,000,000, each Tranche B Lender shall, not
less than 7 days after the date of a Notice of Prepayment or Notice of
Prospective Prepayment, as relevant, advise the Agent whether it
wishes to be included in the portion of such Prepayment or Prospective
Prepayment which, together with all such prior Prepayments and
Prospective Prepayments, does not exceed $20,000,000.  Based on such
notices given to the Agent, which the Agent shall forward to the
Borrower, the Borrower shall:

          (x)  in the case of a Prepayment, prepay on the date
     specified in the Notice of Prepayment the Tranche B Loans of the
     Tranche B Lenders, if any, participating in such Prepayment and
     prepay the Prime Loans on such date or give a Notice of Borrowing
     with respect to a reborrowing of the Tranche A Loans due on such
     date such that the portion of such Prepayment which, together
     with all such prior Prepayments and Prospective Prepayments, does
     not exceed $20,000,000 shall, after giving effect to any
     repayment, prepayment and reborrowing of Loans on such day,
     assuming the conditions precedent set forth in Section 3.02 are
     met on such day, have been applied pro rata (based on the then
     outstanding amounts of the Loans) to the Loans of the Tranche B
     Lenders, if any, participating in such Prepayment and the Tranche
     A Lenders; or

          (y)   in the case of a Prospective Prepayment, the Agent
     shall make such changes in the amounts of the scheduled
     installments due on the Tranche B Loans under Section 2.04(b) and
     the reductions of the Commitments under Section 2.06(c) scheduled
     to occur on the relevant Reduction Date, such that, after giving
     effect to any repayment, prepayment and reborrowing of Loans on
     such day, assuming the conditions precedent set forth in Section
     3.02 are met on such day, the portion of such Prospective
     Prepayment which, together with all such prior Prepayments and
     Prospective Prepayments, does not exceed $20,000,000, shall have
     been applied pro rata (based on the then outstanding amounts of
     the Loans) to the Loans of the Tranche B Lenders, if any,
     participating in such Prospective Prepayment and the Tranche A
     Lenders.
                                 -29-

            (iii) In the case of any Prepayment or Prospective
Prepayment, or a portion thereof, which, together with all prior
Prepayments and Prospective Prepayments as to which notice has been
given under this Section, exceeds $20,000,000, the Borrower shall:

          (x) in the case of a Prepayment, prepay on the date
     specified in the Notice of Prepayment the Tranche B Loans of the
     Tranche B Lenders and prepay the Prime Loans on such date or give
     a Notice of Borrowing with respect to a reborrowing of the
     Tranche A Loans due on such date such that the portion of such
     Prepayment which, together with all such prior Prepayments and
     Prospective Prepayments, exceeds $20,000,000 shall, after giving
     effect to any repayment, prepayment and reborrowing of Loans on
     such day, assuming the conditions precedent set forth in Section
     3.02 are met on such day, have been applied pro rata (based on
     the then outstanding amounts of the Loans) to all of the Loans of
     the Lenders; or
          
          (y) in the case of a Prospective Prepayment, the Agent shall
     make such changes in the amounts of the scheduled installments
     due on the Tranche B Loans under Section 2.04(b) and the
     reductions of the Commitments under Section 2.06(c) scheduled to
     occur on the relevant Reduction Date, such that, after giving
     effect to any repayment, prepayment and reborrowing of Loans on
     such day, assuming the conditions precedent set forth in Section
     3.02 are met on such day, the portion of such Prospective
     Prepayment which, together with all such prior Prepayments and
     Prospective Prepayments, exceeds $20,000,000, shall have been
     applied pro rata (based on the then outstanding amounts of the
     Loans) to all of the Loans of the Lenders.

          (d)  Upon receipt of a Notice of Prepayment or Notice of
Prospective Prepayment pursuant to this Section, the Agent shall
promptly notify each Lender of the contents thereof, and such notice
shall not thereafter be revocable by the Borrower.  The Agent shall
promptly advise each Lender of the portion of any Prepayment or
Prospective Prepayment which is applicable to its Loan determined in
accordance with subsection (c) above and shall also advise such Lender
of the corresponding adjustments in the remaining scheduled reductions
of such Loan under Section 2.04(b) or Section 2.06(c) and (d) as
relevant.  With respect to any prepayment of a

                                 -30-
<PAGE>

Tranche B Loan made as part of a Prepayment or as to the portion of
any installment of a Tranche B Loan which is attributable to a
Prospective Prepayment, the amount of each scheduled installment of
such Loan which would have been required to be paid on a subsequent
Reduction Date but for such Prepayment or Prospective Prepayment shall
be for purposes of this Section 2.07 referred to as an "Eliminated
Payment"; PROVIDED that the "Eliminated Payments" associated with any
prepayment of a Tranche B Loan shall also include the reductions (if
any) in Eliminated Payments occurring under subsection (e)(iii) below
as a consequence of such prepayment.

          (e)  (i) Any prepayment of Prime Loans or Tranche B Loans
under subsection (c)(ii)(x) or subsection (c)(iii)(x) above shall be
effected by payment by the Borrower to the Agent for the accounts of
the relevant Lenders of the principal amount to be prepaid together
with accrued interest thereon to the date of prepayment and, in the
case of the portion of any Tranche B Loans prepaid pursuant to
subsection (c)(iii)(x) above, an amount equal to the excess, if any,
of (x) the net present value, at the time of such prepayment, of all
future scheduled payments of principal and interest with respect to
the corresponding Eliminated Payments, calculated as if such
prepayment were not being made and using a discount rate equal to the
yield, which shall be imputed by linear interpolation from the yields
(as most recently published in Federal Reserve Statistical Release
H.15 (519) or any successor publication thereto) of those United
States Treasury notes which have maturities as close as practicable to
the remaining weighted average life of such Eliminated Payments; OVER
(y) the amount of such prepayment.

         (ii)  If any portion of an installment of any Tranche B Loan
due on a Reduction Date pursuant to Section 2.04(b) is payable due to
a Prospective Prepayment (or portion thereof) described in subsection
(c)(iii)(y) above, the Borrower shall also pay to the Agent for the
account of the relevant Tranche B Lender an amount equal to the
excess, if any, of (x) the net present value, at the time of such
payment, of all future scheduled payments of principal and interest
with respect to the corresponding Eliminated Payments, calculated as
if such Prospective Prepayment (or portion thereof) had not occurred
and using a discount rate equal to the yield, which shall be imputed
by linear interpolation from the yields (as most recently published in
Federal Reserve Statistical Release H.15 (519) or any successor
publication thereto) of those United States Treasury notes which have
maturities as close as practicable to the remaining weighted average
life of such
                                 -31-
<PAGE>

Eliminated Payments; OVER (y) such portion of such installment.

        (iii)  For purposes hereof, any reduction of a scheduled
installment of a Tranche B Loan under Section 2.04 attributable to a
prepayment of such Tranche B Loan under subsection (c)(iii)(x) shall
be applied at the time of such prepayment first to reduce the portion,
if any, of such installment which is then attributable to Prospective
Prepayments described in subsection (c)(iii)(y) above and shall also
reduce (on a pro rata basis, if there is more than one such Eliminated
Payment) the corresponding Eliminated Payments associated with such
portion of such installment.

          SECTION 2.08.  GENERAL PROVISIONS AS TO PAYMENTS. The
Borrower shall make each payment of principal of, and interest on, the
Loans hereunder not later than 11:00 A.M. (New York City time) on the
date when due, in Federal or other funds immediately available in New
York City, to the Agent at its address referred to in Section 9.01. 
The Agent will wire transfer to each Lender, in accordance with the
most recent wire transfer instructions previously delivered by such
Lender to the Agent, the amount of each such payment received by the
Agent for the account of such Lender.  If such payment is received by
the Agent at or before 11:00 A.M. (New York City time) on any date,
such wire transfer shall be made by the Agent on such date.  If such
payment is received after 11:00 A.M. (New York City time), such wire
transfer shall be made by the Agent on the next succeeding Domestic
Business Day.  Whenever any payment of principal of, or interest on,
the Domestic Loans or the Tranche B Loans shall be due on a day which
is not a Domestic Business Day, the date for payment thereof shall be
extended to the next succeeding Domestic Business Day.  Whenever any
payment of principal of, or interest on, the Euro-Dollar Loans shall
be due on a day which is not a Euro-Dollar Business Day, the date for
payment thereof shall be extended to the next succeeding Euro-Dollar
Business Day unless such Euro-Dollar Business Day falls in another
calendar month, in which case the date for payment thereof shall be
the next preceding Euro-Dollar Business Day.  If the date for any
payment of principal is extended by operation of law or otherwise,
interest thereon shall be payable for such extended time.

          SECTION 2.09.  FUNDING LOSSES.  If the Borrower makes any
payment of principal with respect to any Fixed Rate Loan (pursuant to
Article VI or VIII or otherwise) on any day other than the last day of
the Interest Period applicable thereto, or the end of an applicable
period fixed pursuant to
                                 -32-
<PAGE>

Section 2.05(d), or if the Borrower fails to borrow any Fixed Rate
Loans after notice has been given to any Lender in accordance with
Section 2.02(b) or fails to borrow Loans to be advanced under Section
2.12, the Borrower shall reimburse each Lender on demand for any
resulting loss or expense incurred by it (or by any existing or
prospective participant in the related Loan), including (without
limitation) any loss incurred in liquidating or employing deposits
from third parties, but excluding loss of margin for the period after
any such payment or failure to borrow, PROVIDED that such Lender shall
have delivered to the Borrower a certificate as to the amount of such
loss or expense, which certificate shall be conclusive in the absence
of manifest error.

          SECTION 2.10.  COMPUTATION OF INTEREST AND FEES. Interest on
Domestic Loans based on the Prime Rate shall be computed on the basis
of a year of 365 days (or 366 days in a leap year) and paid for the
actual number of days elapsed (including the first day but excluding
the last day).  Interest on Domestic Loans based on the Adjusted CD
Rate and interest on Euro-Dollar Loans shall be computed on the basis
of a year of 360 days and paid for the actual number of days elapsed,
calculated as to each Interest Period or period fixed pursuant to
Section 2.05(d) from and including the first day thereof to but
excluding the last day thereof.  Interest on Tranche B Loans shall be
computed on the basis of a year of 360 days, consisting of 12 months
of 30 days each.

          SECTION 2.11.  REGULATION D COMPENSATION.  Each Tranche A
Lender may require the Borrower to pay, contemporaneously with each
payment of interest on the Tranche A Loans, additional interest on the
Euro-Dollar Loans of such Tranche A Lender at a rate per annum equal
to the excess of (i)(A) the applicable London Interbank Offered Rate
divided by (B) one MINUS the Euro-Dollar Reserve Percentage over (ii)
the rate specified in clause (i)(A).  Any Tranche A Lender wishing to
require payment of such additional interest (x) shall so notify the
Borrower and the Agent, in which case such additional interest on the
Euro-Dollar Loans of such Tranche A Lender shall be payable to such
Tranche A Lender at the place indicated in such notice with respect to
each Interest Period commencing at least five Domestic Business Days
after the giving of such notice and (y) shall notify the Borrower at
least five Domestic Business Days prior to each date on which interest
is payable on the Tranche A Loans of the amount then due it under this
Section.

          SECTION 2.12.  INCREASE OF AGGREGATE LOANS. (a) The
aggregate Commitments and Loans hereunder may from time to

                                 -33-
<PAGE>

time after the first Borrowing be increased by the addition of a new
Lender and its commitment to this facility or by increasing the
Commitment of any existing Lender under this facility, in the manner
described in this Section.

          (b)  At any time that the Borrower desires to increase the
aggregate Commitments and Loans hereunder, it shall give notice
thereof to the Agent, and shall specify whether it wishes such
Commitments and Loans to be Tranche A Commitments and Loans or
Tranche B Commitments and Loans or some combination thereof.  In the
case of any proposed increase in Tranche B Commitments and Loans
hereunder, the Borrower shall, in such notice, state the interest rate
per annum at which such Loans shall be made.  The Agent shall promptly
advise the Lenders of any such notice it receives from the Borrower. 
With respect to any proposed increase in Tranche A Commitments and
Loans hereunder, each existing Tranche A Lender shall, within ten
Domestic Business Days, advise the Agent as to whether it is willing
to provide its share of such increase pro rata in proportion to the
existing Commitments of the Tranche A Lenders.  With respect to any
proposed increase in Tranche B Commitments and Loans hereunder, each
existing Tranche B Lender shall, within ten Domestic Business Days,
advise the Agent as to whether it is willing to provide its share of
such increase pro rata in proportion to the existing Commitments of
the Tranche B Lenders.  If any existing Tranche A or Tranche B Lenders
hereunder are not willing to provide the full amounts of their shares
of any such increase in the Commitments and Loans hereunder, the
resulting shortfall shall be allocated among the remaining Tranche A
or Tranche B Lenders, as relevant, as determined by the Borrower and
the Agent, or the Borrower may designate one or more new Lenders,
satisfactory to the Agent, to provide one or more new Commitments and
Loans hereunder in the amount of such shortfall, and, in the case of
Tranche B Loans, at the rate of interest per annum specified in the
notice of the Borrower to the Agent described above.

          (e)  The increase in existing Commitments or the addition of
Commitments of new Lenders hereunder shall be effected by execution of
an addendum to this Agreement as provided in Section 9.05. 
Simultaneously with the execution of such an addendum, the Borrower
shall execute and deliver to the Agent a Euro-Dollar Note and a
Domestic Note for each Lender that is a new Tranche A Lender, or a
Tranche B Note for each Lender that is a Tranche B Lender making a new
Loan under this Section, in each case dated the date of such addendum,
and shall, in any case, execute and deliver such documents as the
Agent may reasonably request relating to the authorization

                                 -34-
<PAGE>

for and validity of such addendum and, if relevant, such new Note or
Notes.  If the Borrower shall have provided security under Section
5.08 or 5.11, the documents relating to such security shall be amended
as necessary or advisable to take account of the increased Commitments
and Loans hereunder.

          (d)  The Lender executing such addendum shall, not later
than 11:00 A.M. (New York City time) on the date specified in such
addendum, advance a Loan to the Borrower in an amount equal to, in the
case of a new Lender, its Commitment, or, in the case of an existing
Lender, the increase in its Commitment by making such amount
available, in Federal or other funds immediately available in New York
City, to the Agent at its address specified in or pursuant to Section
9.01. If such Loan is a Tranche A Loan, it shall be of the same type
(Prime, CD or Euro-Dollar) as the then-outstanding Tranche A Loans and
the Interest Period for such Tranche A Loan shall commence on such
date and end on the last day of the then current Interest Period for
the then-outstanding Tranche A Loans.  Such Tranche A Loan shall
mature, and the principal amount thereof be due and payable, on the
last day of the Interest Period applicable thereto.  If such Loan is a
Tranche B Loan, the principal thereof shall be payable and interest
thereon shall accrue and be payable as provided in Sections 2.04(b)
and 2.05(e).

          (e)  The borrowing of any Loan by the Borrower under this
Section shall constitute a representation and warranty by the Borrower
to all of the Lenders that:

          (i)  immediately after such borrowing, no Default shall have
     occurred and be continuing; and

          (ii) the fact that the representations and warranties of the
     Borrower contained in this Agreement (except the representation
     and warranty set forth in Section 4.04(d) as to any material
     adverse change which has theretofore been disclosed in writing by
     the Borrower to the Lenders) are true on and as of the date of
     such borrowing.

and do not contravene, or constitute a default under, any provision of
applicable law or regulation or of either Partnership Agreement or of
any other agreement, judgment, injunction, order, decree or other

information and other documents furnished by or on behalf of the
Borrower or any of its Affiliates to the Lenders in connection with

                                 -38-
<PAGE>
any untrue statement of material fact or omit to state a material
fact necessary in order to make the statements contained therein not
misleading.

     (b)  The balance sheet of Energy Partners as of December 31, 1986
and the related statements of income, changes in financial position
and changes in partners' capital for the fiscal year then ended,
reported on by Price Waterhouse and set forth in the 1986 annual
report on Form 10-K for Energy Partners, as filed with the Securities
and Exchange Commission, a copy of which has been delivered to each of
the Lenders, fairly present, in conformity with generally accepted
accounting principles, the financial position of Energy Partners as of
such date and its results of operations and changes in financial
position for such fiscal year.

     (c)  The unaudited balance sheet of Energy Partners as of March
31, 1987 and the related unaudited statements of income, changes in
financial position and changes in partners' capital for the three
months then ended, set forth in the quarterly report of Energy
Partners for the fiscal quarter ended March 31, 1987 as filed with the

change in the business, properties, financial position, results of
operations or current operating environment of Energy Partners or of
the Borrower.

     SECTION 4.05.  LITIGATION.  There is no action, suit or
proceeding pending against, or to the knowledge of the Borrower
threatened against or affecting, the Borrower or any of its Affiliates
before any court or arbitrator or any governmental body, agency or
official in which there is a reasonable possibility of an adverse
decision which could materially adversely affect the Borrower's
ability to perform its obligations under this Agreement or which in
any manner draws into question the validity of this Agreement, the
Notes or the Mortgages.

     SECTION 4.06.  COMPLIANCE WITH ERISA.  (a)  Each ERISA
Obligor has fulfilled in all material respects its

                                 -39-

obligations under the minimum funding standards of ERISA and the Code
with respect to each Plan and is in compliance in all material

Code, and with respect to each Plan there is not outstanding any
material liability currently payable (other than premium payments
outstanding for 60 days or less) to the PBGC or a Plan under Title IV
of ERISA.

     (b)  As of the date of this Agreement, the sum, for all Excluded

assets of such Excluded Plan (excluding for these purposes any accrued
but unpaid contributions) does not exceed $22,000,000.

States Federal income tax information returns and all other material
tax returns which are required to be filed by them and have paid all
taxes due pursuant to such returns or pursuant to any assessment
received by either of them (other than such taxes as are being
contested in good faith in appropriate proceedings).  The charges,
accruals and reserves on the books of the Borrower and on the books of
Energy Partners in respect of taxes or other governmental charges are,
in the opinion of the Borrower, adequate.

     SECTION 4.08.  TITLE TO ASSETS.  The Borrower has, to the best of
its knowledge, valid and defensible title to the Petroleum Properties,
subject to no Liens other than Liens permitted under Section 5.10, and
the Borrower's net revenue interests in the various Petroleum
Properties are as shown in the Most Recent Engineering Report.  Except
for instances which do not in the aggregate materially detract from
the value of such leases or materially impair the use thereof in the
operation of its business, the Borrower enjoys peaceful, lawful and
undisturbed possession under all leases included in the Petroleum
Properties and such leases are valid, subsisting, in full force and
effect, and are not subject to any

                                 -40-
<PAGE>

terms which are not usual and customary in similar transactions
negotiated on an arms-length basis.

Event, or an event described in clause (II) or (III) of Section
5.11(a), has occurred until it has complied with Section 5.11(a) or
such compliance is, pursuant to a waiver granted under Section 5.11(b)
or pursuant to the provisions of Section 5.11(c), no longer required. 
For purposes of this Section, a Rollover shall not be deemed an
incurrence of Debt.

     SECTION 5.08.  COVERAGE RATIOS; SECURITY  (a)  If the
Life-of-Reserves Coverage Ratio set forth in any certificate delivered
pursuant to Section 5.01(c) or Coverage Report delivered pursuant to

then, within 60 days of the date of such report, the Borrower shall
(i) reduce Debt, (ii) in accordance with Section 2.07(c), adjust the
amounts of installments of Tranche B Loans under Section 2.04(b) and
the amounts of mandatory reductions of Commitments under Section
2.06(c) so that amounts scheduled to be paid under such Sections are
reduced for later Reduction Dates and increased (by an equal amount in
aggregate) for earlier Reduction Dates or (iii) acquire additional
Recognized Proved Reserves (acceptable to the Required Lenders and

Engineer and delivered to the Lenders within such 60-day period, to
the Most Recent Engineering Report) such that, based on a new Coverage
Report delivered to the Lenders within such 60-day period, the
Life-of-Reserves Coverage Ratio is equal to or greater than 1.75 and
the Annual Coverage Ratio is equal to or greater than 1.20; PROVIDED
that, if a Triggering Event, or an event described in clause (II) or
(III) of Section 5.11(a), has occurred, the Life-of-Reserves Coverage
Ratio shall not on any day be less than 1.90 unless the Borrower has
complied with Section 5.11(a) or such compliance is, pursuant to a
waiver granted under Section 5.11(b) or pursuant to the provisions of
Section 5.11(c), no longer required.

     (b)  If, on any day, the Life-of-Reserves Coverage Ratio is less
than the Collateral Threshold on such day, the Borrower shall, not
later than 60 days thereafter, either (i) have delivered to the Agent
evidence satisfactory to the Agent (which shall include opinions of
counsel) that Mortgages have been executed and recorded as necessary
to perfect for the benefit of the Lenders liens having first priority
(except for Permitted Liens), securing payment of principal of and
interest on the Notes and all other amounts payable by the Borrower
under this Agreement and covering the lesser of (x) the Lenders' Pro
Rata Share of 80% (in Relative Value) of

                                 -46-

the Petroleum Properties not subject to Liens described in Section
5.10(a) and (y) such Petroleum Properties (l) the Cash Flow Available
for Debt Service from which for the period of twenty fiscal years
commencing with the fiscal year in which the date of determination
occurs equals or exceeds (2) 190% of the sum of the aggregate
outstanding principal amount of the Loans and interest scheduled to
accrue on the Loans (using the interest rates for the Loans as set
forth in the most recent Approved Assumptions) or (ii) reduce Debt or
acquire additional Recognized Proved Reserves (acceptable to the
Required Lenders and included in a supplement, prepared by an
Independent Petroleum Engineer and delivered to the Lenders within
such 60-day period, to the then Most Recent Engineering Report) such
that, based on a new Coverage Report delivered to the Lenders within
such 60-day period, the Life-of-Reserves Coverage Ratio is equal to or
greater than the Collateral Threshold; PROVIDED that if the
Life-of-Reserves Coverage Ratio, after giving effect to any incurrence
of Debt, Restricted Payment or sale or other disposition of assets
(including any exchange of Petroleum Properties for other oil and gas
properties) by the Borrower, would be less than the Collateral
Threshold, the Borrower shall, as a precondition to such incurrence of
Debt, Restricted Payment or sale (or exchange) or other disposition of
assets, comply with clause (b)(i) above.

     (c)  If the Borrower provides security pursuant to clause (b)(i)
above, it shall at all times thereafter maintain a perfected first
priority (except as aforesaid) lien for the benefit of the Lenders
covering the lesser of (l) the Lenders' Pro Rata Share (as calculated
from time to time) of 80% (in Relative Value) of the Petroleum
Properties not subject to Liens described in Section 5.10(a) and (2)
such Petroleum Properties (x) the Cash Flow Available for Debt Service
from which for the period of twenty fiscal years commencing with the
fiscal year in which the date of determination occurs equals or
exceeds (y) 190% of the sum of the aggregate outstanding principal
amount of the Loans and interest scheduled to accrue on the Loans
(using the interest rates for the Loans as set forth in the most
recent Approved Assumptions).

     (d)  The "Pro Rata Share" of any holder of any Debt of the
Borrower (other than Debt of the Borrower Guaranteed by another
Person, Subordinated Debt, Debt secured by any Lien on any asset of
the Borrower pursuant to Section 5.10(a) or (e), or Debt incurred in
violation of this Agreement) at any time is the then outstanding
principal amount of such Debt as a percentage of the then outstanding
total principal amount of the Borrower's Debt other than (w) Debt of
the Borrower

Guaranteed by another Person, (x) Subordinated Debt, (y) Debt secured
by a Lien on any asset of the Borrower pursuant to Section 5.10(a) or
(e) and (z) Debt incurred in violation of this Agreement; and the
"Collateral Threshold" is, if Santa Fe Southern Pacific and its
Wholly-Owned Subsidiaries' aggregate ownership of limited partnership
units of Energy Partners is, as a percentage of total outstanding
limited partnership units of Energy Partners, (i) greater than or
equal to 50%, 1.90, (ii) less than 50% but greater than or equal to
25%, 2.15, or (iii) less than 25%, 2.65.

declare or make any Restricted Payments if (a) after giving effect to
such Restricted Payment, a Default shall have occurred and be
continuing, or (b) Santa Fe Southern Pacific and its Wholly-Owned
Subsidiaries own in aggregate, less than 50% of the outstanding
limited partnership units of Energy Partners and the Life-of-Reserves
Ratio is, after giving effect to such Restricted Payment, less than
2.05. Furthermore, the Borrower shall not, after a Triggering Event,
or an event described in clause (II) or (III) of Section 5.11(a), has
occurred, make any Restricted Payment until it has complied with
Section 5.11(a) or such compliance is, pursuant to a waiver granted
under Section 5.11(b) or pursuant to Section 5.11(c), no longer
required.

     SECTION 5.10.  NEGATIVE PLEDGE.  The Borrower will not create,
assume or suffer to exist any Lien on any asset now owned or hereafter
acquired by it, except:

          (a)  any Lien existing on any oil and gas interest, property
     or prospect acquired by the Borrower which Lien was in existence
     prior to such acquisition and was not created in contemplation of
     such acquisition; PROVIDED that no more than one-third (in
     Relative Value) of the Petroleum Properties shall at any time be
     subject to such Liens;

          (b)  Permitted Liens;

          (c)  (i) Liens securing the Loans and any other obligations
     of the Borrower under this Agreement and (ii) so long as such
     Liens described in clause (i) exist, Liens on Petroleum
     Properties securing other Debt of the Borrower (other than Debt
     of the Borrower Guaranteed by another Person, Subordinated Debt,
     Debt secured by any Lien on any asset of the Borrower pursuant to
     Section 5.10(a) or (e), or Debt incurred in violation of this
     Agreement); PROVIDED
                                 -48-
<PAGE>
     that the Relative Value of such Petroleum Properties, in relation
     to all Petroleum Properties subject to Liens described in this
     clause (c), does not exceed the Pro Rata Share of the holders of
     such other Debt;

          (d)  any Lien arising pursuant to any order of attachment,
     distraint or similar legal process arising in connection with
     court proceedings so long as the execution or other enforcement
     thereof is effectively stayed and the claims secured thereby are
     being contested in good faith by appropriate proceedings; and
          
          (e)  Liens on assets which do not (directly or indirectly)
     constitute oil and gas interests, properties or prospects,
     PROVIDED that aggregate principal amount of Debt secured thereby
     does not at any time exceed $10,000,000.

     SECTION 5.11.  PROVISION OF SECURITY UPON TRIGGERING EVENT. 
(a) Subject to the provisions of subsection (c) below, if (I) a
Triggering Event shall have occurred or (II) there shall be any change
in the identity of the Managing General Partner or of the Special
General Partner of either of the Borrower or Energy Partners or (III)
an event described in the definition of "Triggering Event" (for these
purposes replacing "Santa Fe Energy" whenever it occurs with "Santa Fe
Natural Resources") shall have occurred, the Borrower shall, not later
than 60 days after such event, (if it has not theretofore provided
security pursuant to Section 5.08(a) or is not at such time
maintaining such security in accordance with Section 5.08(c)) have
delivered to the Agent evidence satisfactory to the Agent (which shall
include opinions of counsel) that Mortgages have been executed and
recorded as necessary to perfect for the benefit of the Lenders liens
having first priority (except for Permitted Liens), securing payment
of principal of and interest on the Notes and all other amounts
payable by the Borrower under this Agreement and covering the lesser
of (l) the Lenders' Pro Rata Share of 80% (in Relative Value) of the
Petroleum Properties not subject to Liens described in Section 5.lO(a)
and (2) such Petroleum Properties (x) the Cash Flow Available for Debt
Service from which for the period of twenty fiscal years commencing
with the fiscal year in which the date of determination occurs equals
or exceeds (y) 190% of the aggregate outstanding principal amount of
the Loans.
                                 -49-
<PAGE>
     (b)  The Borrower shall, if required to provide security pursuant
to subsection (a) above, at all times there after (unless the Required
Lenders waive such requirement, the consent of the Lenders to a
request for such waiver not to be unreasonably withheld in light of,
among other things, the considerations identified in clause (ii) of
subsection (c) below) maintain a perfected first priority (except as
aforesaid) lien for the benefit of the Lenders covering the lesser of
(1) the Lenders' Pro Rata Share (as calculated from time to time) of
80% (in Relative Value) of the Petroleum Properties not subject to
Liens described in Section 5.10(a) and (2) such Petroleum Properties
(x) the Cash Flow Available for Debt Service from which for the period

date of determination occurs equals or exceeds (y) 190% of the
aggregate outstanding principal amount of the Loans.

     (c)  The Borrower need not comply with the provisions of
subsection (a) above, if, within the 60-day period referred to

Fe Pacific Exploration is the Managing General Partner, a new board of
directors of Santa Fe Pacific Exploration is elected which is
comprised entirely of persons who are not employees, officers,
directors or affiliates of Santa Fe Natural Resources or of any
affiliate of Santa Fe Natural Resources (other than Santa Fe Pacific
Exploration) and (ii) in any case, the Required Lenders have not
determined, taking into account the composition of the board of
directors of the Managing General Partner, that such event may result
in a change of management policy that may adversely affect the
interests of the Lenders.  Each Lender agrees to respond to the Agent
with respect to any request for a determination under clause (ii)
above within five Domestic Business Days of such Lender's receipt of
such request.

     SECTION 5.12.  MERGER; SALE OR ABANDONMENT OF ASSETS: RELEASE OF
COLLATERAL. (a)  The Borrower will not merge or consolidate with any
other Person unless the surviving Person is the Borrower or is a
Person directly or indirectly controlling, controlled by or under
common control with Santa Fe Southern Pacific (the word "control"
having for purposes hereof the meaning assigned thereto in the
definition of Affiliate) and unless, after giving effect thereto, no
Default shall have occurred and be continuing.  The Borrower will not
sell, assign, lease or otherwise transfer or abandon any Petroleum
Properties or any proceeds thereof or rights with respect thereto
without the prior written consent of the Required Lenders except that
(i) the Borrower may sell Hydrocarbons after severance in the ordinary
course of its
                                 -50-
<PAGE>

business; (ii) the Borrower may sell, in any period of twelve months,
Petroleum Properties having an aggregate fair market value not in
excess of $25,000,000, PROVIDED that (A) the aggregate fair market
value of all Petroleum Properties sold pursuant to this clause (ii)
during the term of this Agreement shall not exceed $50,000,000 and (B)
no sale of Petroleum Properties may be made under this clause (ii) if,
after giving effect to such sale and the use of proceeds thereof,
(1) a Default would exist, or (2) the Life-of-Reserves Coverage Ratio
would be less than 1.75 or the Annual Coverage Ratio would be less
than 1.20; (iii) the Borrower may exchange any Petroleum Properties
for any other oil and gas properties having an equivalent fair market
value provided such exchange is otherwise permitted by this Agreement
and PROVIDED that, after giving effect thereto, (x) no Default would
exist, and (y) the Life-of-Reserves Coverage Ratio would equal or
exceed 1.75 and the Annual Coverage Ratio would equal or exceed 1.20;
(iv) the Borrower may sell, lease or otherwise transfer (through

and gas property which the Managing General Partner has determined in
good faith (and, if such property consists of one or more line items
in the Most Recent Engineering Report, so certified to the Agent) is
incapable of producing Hydrocarbons at a level sufficient to produce
gross revenues in excess of the sum of associated royalties, operating
costs and windfall profits, production, ad valorem, severance and
income taxes.

     (b)  If, at any time, the Borrower is required at such time
pursuant to Sections 5.08(c) and/or 5.11(b) to maintain security
theretofore provided under Sections 5.08(b) and/or 5.11(a), the Agent

whether immediate, incidental or ultimate, of purchasing or carrying
any "margin stock" within the meaning of Regulation G or Regulation U.

be, and the Notes shall thereupon become, immediately due and payable
without presentment, demand, protest or other notice of any kind, all
of which are

                                 -54-

TRANCHE A LOANS.  If, on the last day of any Interest Period, the
Borrower fails to borrow Tranche A Loans in accordance with the Notice
of Borrowing required to be given with respect to a Borrowing on such

presentment, demand, protest or notice of any kind, all of which are
hereby waived by the Borrower.

     SECTION 6.04.  ADDITIONAL AMOUNT PAYABLE WITH RESPECT TO TRANCHE
B LOANS.  Together with any payment of any Tranche B Loan pursuant to
Section 6.01 or 6.03 above, the Borrower shall pay to the relevant
Tranche B Lender an amount equal to the excess, if any, of (x) all
future scheduled payments of principal and interest with respect to
the corresponding Eliminated Payments, calculated as if such payment
were not being made and using a discount rate equal to the yield,
which shall be imputed by linear interpolation from the yields (as
most recently published in Federal Reserve Statistical Release H.15
(519) or any successor publication thereto) of those United States
Treasury notes which have maturities as close as practicable to the
remaining weighted average life of such Eliminated Payments; over (y)
the amount of such payment. With respect to any such payment pursuant
to Section 6.01 or 6.03 above of a Tranche B Loan, the corresponding
"Eliminated Payments" shall mean all scheduled installments of such
Loan which would have been required to be paid on subsequent Reduction
Dates but for such payment pursuant to Section 6.01 or 6.03 above;
PROVIDED that the "Eliminated Payments" associated with any such
payments shall also include the Eliminated Payments (as defined in
Section 2.07(d) associated with any portion of any such scheduled
installment which is then
                                 -55-

attributable to Prospective Prepayments described in Section
2.07(c)(iii)(y).

this Agreement or any Mortgage or any borrowing hereunder; (ii) the
performance or observance of any of the covenants or agreements of the
Borrower; (iii) the satisfaction of any condition specified in Article
III or Section 2.12, except receipt of items required to be delivered

signed by the proper party or parties.

     SECTION 7.06.  INDEMNIFICATION.  Each Lender shall, ratably in
accordance with its outstanding Loans, indemnify the Agent (to the
extent not reimbursed by the Borrower) against any cost, expense

loss or liability (except such as result from the Agent's gross
negligence or willful misconduct) that the Agent may suffer or incur
in connection with this Agreement or any action taken or omitted by
the Agent hereunder.

     SECTION 7.07.  CREDIT DECISION.  Each Lender acknowledges that it
has, independently and without reliance upon the Agent or any other
Lender, and based on such documents and information as it has deemed
appropriate, made its own credit analysis and decision to enter into
this Agreement. Each Lender also acknowledges that it will,
independently and without reliance upon the Agent or any other sender,
and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in
taking or not taking any action under this Agreement. 

     SECTION 7.08.  FEES.  The Borrower shall pay to the Agent the
arrangement and commitment fee set forth in the letter from the Agent
to the Borrower dated June 8, 1987, and shall pay to the Agent on the
date of the first Borrowing and on each anniversary thereof, so long
as any Loan remains outstanding, an agency and engineering fee of
$30,000.                                 -57-

                             ARTICLE VIII

          CHANGE IN CIRCUMSTANCES AFFECTING TRANCHE A LENDERS

     SECTION 8.01.  BASIS FOR DETERMINING INTEREST RATE INADEQUATE OR
UNFAIR.  If on or prior to the first day of any Interest Period:

          (a)  the Agent is advised by the Reference Banks that
     deposits in dollars (in the applicable amounts) are not being
     offered to the Reference Banks in the relevant market for such
     Interest Period, or 

          (b)  Tranche A Lenders having 66 2/3% or more of the
     aggregate amount of the Tranche A Commitments advise the Agent
     that the Adjusted CD Rate or the London Interbank Offered Rate,
     as the case may be, as determined by the Agent will not
     adequately and fairly reflect the cost to such Tranche A Lenders
     of funding their Fixed Rate Loans for such Interest Period,

the Agent shall forthwith give notice thereof to the Borrower and the
Tranche A Lenders, whereupon until the Agent notifies the Borrower
that the circumstances giving rise to such suspension no longer exist,
the obligations of the Tranche A Lenders to make CD Loans or
Euro-Dollar Loans, as the case may be, shall be suspended. Unless the
Borrower notifies the Agent at least two Domestic Business Days before
the date of any Fixed Rate Borrowing for which a Notice of Borrowing
has previously been given that it elects not to borrow on such date,
such Borrowing shall instead be made as a Prime Borrowing.

     SECTION 8.02.  ILLEGALITY. If, after the date of this Agreement,
the adoption of any applicable law, rule or regulation, or any change
therein, or any change in the interpretation or administration thereof
by any governmental authority, central bank or comparable agency
charged with the interpretation or administration thereof, or
compliance by any Tranche A Lender (or its Euro-Dollar Lending Office)
with any request or directive (whether or not having the force of law)
of any such authority, central bank or comparable agency shall make it
unlawful or impossible for any Tranche A Lender (or its Euro-Dollar
Lending Office) to make, maintain or fund its Euro-Dollar Loans and
such Tranche A Lender shall so notify the Agent, the Agent shall
forthwith give notice thereof to

                                 -58-
<PAGE>

the other Tranche A Lenders and the Borrower, whereupon until such
Tranche A Lender notifies the Borrower and the Agent that the
circumstances giving rise to such suspension no longer exist, the
obligation of such Tranche A Lender to make Euro-Dollar Loans shall be
suspended. Before giving any notice to the Agent pursuant to this
Section, such Tranche A Lender shall designate a different Euro-Dollar
Lending Office if such designation will avoid the need for giving such
notice and will not, in the judgment of such Tranche A Lender, be
otherwise materially disadvantageous to such Tranche A Lender. If such
Tranche A Lender shall determine that it may not lawfully continue to
maintain and fund any of its outstanding Euro-Dollar Loans to maturity
and shall so specify in such notice, the Borrower shall immediately
prepay in full the then outstanding principal amount of each such
Euro-Dollar Loan, together with accrued interest thereon. Concurrently
with prepaying each such Euro-Dollar Loan, the Borrower shall borrow a
Prime Loan in an equal principal amount from such Tranche A Lender (on
which interest and principal shall be payable contemporaneously with
the related Euro-Dollar Loans of the other Tranche A Lenders), and
such Tranche A Lender shall make such a Prime Loan. 

     SECTION 8.03.  INCREASED COST AND REDUCED RETURN.  (a)  If after
the date hereof, the adoption of any applicable law, rule or
regulation, or any change therein, or any change in the interpretation
or administration thereof by any governmental authority, central bank
or comparable agency charged with the interpretation or administration
thereof, or compliance by any Tranche A Lender (or its Lending Office)
with any request or directive (whether or not having the force of law)
of any such authority, central bank or comparable agency:

          (i)  shall subject any Tranche A Lender (or its Lending
     Office) to any tax, duty or other charge with respect to its
     Fixed Rate Loans, its Notes or its obligation to make Fixed Rate
     Loans, or shall change the basis of taxation of payments to any
     Tranche A Lender (or its Lending Office) of the principal of or
     interest on its Fixed Rate Loans or any other amounts due under
     this Agreement in respect of its Fixed Rate Loans or its
     obligation to make Fixed Rate Loans (except for changes with
     respect to tax on net income or any tax computed by reference to
     net income of such Tranche A Lender or its applicable Lending
     Office imposed by the jurisdiction in which such Tranche A
     Lender's principal executive office or applicable Lending Office
     is located); or

                                 -59-
<PAGE>

          (ii)  shall impose, modify or deem applicable any reserve,
     special deposit or similar requirement (including, without
     limitation, any such requirement imposed by the Board of
     Governors of the Federal Reserve System, but excluding (A) with
     respect to any CD Loan any such requirement included in an
     applicable Domestic Reserve Percentage and (B) with respect to
     any Euro-Dollar Loan any such requirement for which such Tranche
     A Lender is entitled to compensation during the relevant Interest
     Period pursuant to Section 2.11) against assets of, deposits with
     or for the account of, or credit extended by, any Tranche A
     Lender (or its Lending Office) or shall impose on any Tranche A
     Lender (or its Lending Office) or on the United States market for
     certificates of deposit or the London interbank market any other
     condition affecting its Fixed Rate Loans, its Notes or its
     obligation to make Fixed Rate Loans;

and the result of any of the foregoing is to increase the cost to such
Tranche A Lender (or its Lending Office) of making or maintaining any
Fixed Rate Loan, or to reduce the amount of any sum received or
receivable by such Tranche A Lender (or its Lending Office) under this
Agreement or under its Notes with respect thereto, by an amount deemed
by such Tranche A Lender to be material, such Tranche A Lender shall
promptly after its determination of such occurrence give notice
thereof to the Agent (which shall promptly give notice to the
Borrower), and the Borrower shall pay to such Tranche A Lender from
time to time, within 30 days of demand, such amount as such Tranche A
Lender certifies to be the amount that will compensate it for such
increased costs, provided that the Borrower's obligation to pay such
Tranche A Lender shall be limited to the increased costs that are
attributable to the period of time commencing with the date 30 days
prior to the date on which such Tranche A Lender's notice is received
by the Borrower.

          (b)  If after the date hereof, any Tranche A Lender shall
     have determined that the adoption of any applicable law, rule or
     regulation regarding capital adequacy, or any change therein, or
     any change in the interpretation or administration thereof by any
     governmental authority, central bank or comparable agency charged     
     with the interpretation or administration thereof, or compliance
     by any Tranche A Lender (or its Lending Office) with any request
     or directive regarding capital adequacy (whether or not having
     the force of law)

                                 -60-
<PAGE>

     of any such authority, central bank or comparable agency, has or
     would have the effect of reducing the rate of return on such
     Tranche A Lender's capital as a consequence of its obligations
     hereunder to a level below that which such Tranche A Lender could
     have achieved but for such adoption, change or compliance (taking
     into consideration such Tranche A Lender's policies with respect
     to capital adequacy) by an amount deemed by such Tranche A Lender
     to be material, such Tranche A Lender shall promptly after its
     determination of such occurrence give notice thereof to the Agent
     (which will promptly give notice to the Borrower), and the
     Borrower shall pay to such Tranche A Lender from time to time,
     within 30 days of demand, such amount as such Tranche A Lender
     certifies to be the amount that will compensate it for such
     reduction provided that the Borrower's obligation to pay such
     Tranche A Lender shall be limited to the reduction that is
     attributable to the period of time commencing with the date 30
     days prior to the date on which such Tranche A Lender's notice is
     received by the Borrower.

          (c)  Each Tranche A Lender will promptly notify the Borrower
     and the Agent of any event of which it has knowledge, occurring
     after the date hereof, which will entitle such Tranche A Lender
     to compensation pursuant to this Section and will designate a
     different Lending Office if such designation will avoid the need
     for, or reduce the amount of, such compensation and will not, in
     the judgment of such Tranche A Lender, be otherwise materially
     disadvantageous to such Tranche A Lender. A certificate of any
     Tranche A Lender claiming compensation under this Section and
     setting forth the additional amount or amounts to be paid to it
     hereunder shall be conclusive in the absence of manifest error.
     In determining such amount, such Tranche A Lender may use any
     reasonable averaging and attribution methods.

     SECTION 8.04.  PRIME LOANS SUBSTITUTED FOR AFFECTED FIXED RATE
LOANS.  If (i) the obligation of any Tranche A Lender to make
Euro-Dollar Loans has been suspended pursuant to Section 8.02 or (ii)
any Tranche A Lender has demanded compensation under Section 8.03(a)
and the Borrower shall, by at least five Euro-Dollar Business Days'
prior notice to such Tranche A Lender through the Agent, have elected
that the provisions of this Section shall apply to such Tranche A
Lender, then, unless and until such Tranche A Lender notifies the
Borrower that the circumstances giving rise to such suspension or
demand for compensation no longer apply:

          (a)  all Loans which would otherwise be made by such Tranche
     A Lender as CD Loans or Euro-Dollar

                                 -61-
<PAGE>

     Loans, as the case may be, shall be made instead as Prime Loans
     (on which interest and principal shall be payable
     contemporaneously with the related Fixed Rate Loans of the other
     Tranche A Lenders), and 

          (b)  after each of its CD Loans or Euro-Dollar Loans, as the
     case may be, has been repaid, all payments of principal which
     would otherwise be applied to repay such Fixed Rate Loans shall     
     be applied to repay its Prime Loans instead.

     SECTION 8.05.  SUBSTITUTION OF LENDER.  If (i) the obligation of
any Tranche A Lender to make Euro-Dollar Loans has been suspended
pursuant to Section 8.02 or (ii) any Tranche A Lender has demanded
compensation under Section 8.03, the Borrower shall have the right,
with the assistance of the Agent, to seek a mutually satisfactory (to
the Borrower and the Agent) substitute lender or lenders (which may be
one or more of the Lenders) to purchase the Notes and assume the
Tranche A Commitment of such Tranche A Lender.

                              ARTICLE IX

                             MISCELLANEOUS

     SECTION 9.01.  NOTICES.  All notices, requests and other
communications to any party hereunder shall be in writing (including
bank wire, telex, telecopy or similar writing) and shall be given to
such party at its address or telex or telecopy number set forth on the
signature pages hereof or such other address or telex or telecopy
number as such party may hereafter specify for the purpose by notice
to the Agent and the Borrower. Each such notice, request or other
communication shall be effective (i) if given by telex or telecopy,
when such telex or telecopy is transmitted to the telex or telecopy
number specified in this Section and, in the case of a telex, the
appropriate answerback is received, (ii) if given by mail, 72 hours
after such communication is deposited in the mails with first class
postage prepaid, addressed as aforesaid or (iii) if given by any other
means, when delivered at the address specified in this Section;
PROVIDED that notices to the Agent under Article II and requests to
the Lenders under Section 5.11(c)(ii) shall not be effective until
received.

                                 -62-
<PAGE>

     SECTION 9.02.  NO WAIVERS.  No failure or delay by the Agent or
any Lender in exercising any right, power or privilege hereunder or
under any Note or any Mortgage shall operate as a waiver thereof nor
shall any single or partial exercise thereof preclude any other or
further exercise thereof or the exercise of any other right, power or
privilege. The rights and remedies herein provided shall be cumulative
and not exclusive of any rights or remedies provided by law.

     SECTION 9.03.  EXPENSES; DOCUMENTARY TAXES.  The Borrower shall
pay (i) all reasonable out-of-pocket expenses of the Agent, including
reasonable fees and disbursements of special counsel for the Lenders
and the Agent, in connection with the preparation of this Agreement,
any waiver or consent hereunder or any amendment hereof or any Default
or alleged Default hereunder, (ii) all out-of-pocket expenses of the
Agent, including fees and disbursements of counsel for the Lenders and
the Agent, in connection with the preparation, execution, recordation,
or administration of any Mortgage and (iii) if an Event of Default
occurs, all out-of-pocket expenses incurred by the Agent or any
Lender, including fees and disbursements of counsel, in connection
with such Event of Default and collection and other enforcement
proceedings resulting therefrom. The Borrower shall indemnify each
Lender against any transfer taxes, recording taxes, documentary taxes,
assessments or charges made by any governmental authority by reason of
the execution and delivery of this Agreement or the Notes or of the
execution and recordation of any Mortgage.

     SECTION 9.04.  SHARING OF SET-OFFS.  Each Lender agrees that if
it shall, by exercising any right of set-off or counterclaim or
otherwise, receive payment of a proportion of the aggregate amount of
principal and interest due with respect to any Note held by it which
is greater than the proportion received by any other Lender in respect
of the aggregate amount of principal and interest due with respect to
any Note held by such other Lender, the Lender receiving such
proportionately greater payment shall purchase such participations in
the Notes held by the other Lenders, and such other adjustments shall
be made, as may be required so that all such payments of principal and
interest with respect to the Notes held by the Lenders shall be shared
by the Lenders pro rata; PROVIDED that nothing in this Section shall
impair the right of any Lender to exercise any right of set-off or
counterclaim it may have and to apply the amount subject to such
exercise to the payment of indebtedness of the Borrower other than its
indebtedness under the Notes. The Borrower

                                 -63-
<PAGE>

agrees, to the fullest extent it may effectively do so under
applicable law, that any holder of a participation in a Note, whether
or not acquired pursuant to the foregoing arrangements, may exercise
rights of set-off or counterclaim and other rights with respect to
such participation as fully as if such holder of a participation were
a direct creditor of the Borrower in the amount of such participation. 

     SECTION 9.05.  AMENDMENTS AND WAIVERS.  Any provision of this
Agreement or the Notes or the Mortgage may be amended or waived if,
but only if, such amendment or waiver is in writing and is signed by
the Borrower and the Required Lenders (and, if the rights or duties of
the Agent are affected thereby, by the Agent); PROVIDED that no such
amendment or waiver shall, unless signed by all the Lenders, (i)
increase the Commitment of any Lender or subject any Lender to any
additional obligation, except as contemplated by Section 2.12 and the
further PROVISO below, (ii) reduce the principal of or rate of
interest on any Loan or any fees hereunder, (iii) effect any amendment
in the provisions of Section 2.07, 6.03, 6.04 or 9.04, (iv) effect any
amendment in Section 5.08 or 5.11 or permit the release of any
Mortgage except pursuant to a waiver granted under Section 5.11(b) or
pursuant to the provisions of Section 5.12(b), (v) postpone the date
fixed for any payment of principal of or interest on any Loan or any
fees hereunder or (vi) change the percentage of the Commitments or of
the aggregate unpaid principal amount of the Notes which shall be
required for the Lenders or any of them to take any action under this
Section or any other provision of this Agreement; PROVIDED FURTHER
that the signature pages hereof may be amended to include a new Lender
and to set forth its Commitment or to increase the Commitment of an
existing Lender (as contemplated by Section 2.12) and to reflect the
resulting increase in the aggregate Commitments by execution of an
addendum hereto by the Borrower, the Agent and such Lender, and all
references herein, or in any other document, to this Agreement shall
thereafter be deemed to refer to this Agreement as amended by such
addendum. The Agent shall promptly give notice to the Borrower and all
Lenders of any amendment or waiver of this Agreement or the Notes or
any Mortgage.

     SECTION 9.06.  SUCCESSORS AND ASSIGNS.  (a)  The provisions of
this Agreement shall be binding upon and inure to the benefit of the
parties hereto and their respective successors and assigns, except
that (i) the Borrower may not assign or otherwise transfer any of its
rights under this Agreement and (ii) no Tranche A Lender may, without
the prior written consent of the Borrower, assign any Tranche A Loan

                                 -64-
<PAGE>

hereunder; PROVIDED that nothing herein shall be deemed to prohibit
the granting by any Tranche A Lender of participation in any Tranche A
Loan hereunder or the sale, assignment, pledge or other transfer by
any Tranche A Lender of its Notes and its rights thereunder to any
Federal Reserve Bank. 

     (b)  The Agent and the Borrower may, for all purposes of this
Agreement, treat any Lender as the holder of any Note drawn to it or
its order (and owner of the Loans evidenced thereby)  until written
notice of assignment, participation or other transfer shall have been
received by them and reflected on the Borrower's books; PROVIDED that
no Tranche A Lender or participant shall give any such written notice
with respect to any participation referred to in the PROVISO contained
in subsection (a) prior to the occurrence of an Event of Default. The
Borrower shall promptly record on its books all notices it receives
under this subsection (b). In the case of any transfer of a Tranche B
Note, the Borrower shall execute and deliver a new Tranche B Note
payable to the transferee upon surrender of the old Tranche B Note
duly endorsed or accompanied by a written instrument of transfer duly
executed by the registered holder of the old Tranche B Note. Such new
Tranche B Note shall be dated and bear interest from the date to which
interest has been paid on the surrendered Tranche B Note or from the
date of the surrendered Note if no interest has been paid thereon. 

     (c)  No assignee, participant or other transferee of any Tranche
A Lender's rights shall be entitled to receive any greater payment
under Section 8.03 than such Lender would have been entitled to
receive with respect to the rights transferred, except in the case of
an assignment made with the Borrower's prior written consent or by
reason of the provisions of Section 8.02 or 8.03 requiring such Lender
to designate a different Lending Office under certain circumstances or
at a time when the circumstances giving rise to such greater payment
did not exist.

     (d)  If any Reference Bank assigns its Notes to an unaffiliated
institution, the Agent shall, in consultation with the Borrower and
with the consent of the Tranche A Lenders, appoint another bank to act
as a Reference Bank hereunder.

     SECTION 9.07.  COLLATERAL.  Each of the Lenders represents to the
Agent and each of the other Lenders that it in good faith is not
relying upon any "margin stock" (as defined in Regulation G and
Regulation U)  as collateral in the

                                 -65-
<PAGE>

extension or maintenance of the credit provided for in this Agreement. 

     SECTION 9.08.  REPRESENTATIONS OF LENDERS.  Each Tranche A Lender
represents that it is making its Loan in the ordinary course of its
commercial banking business and not with a view toward distribution
thereof, and each Tranche B Lender represents that it is acquiring its
Tranche B Note for investment for its own account and not with a view
toward distribution thereof, subject, nevertheless, to any requirement
of law that the disposition of its property shall at all times be
within its control.

     SECTION 9.09.  CONFIDENTIALITY.  Any information which any of the
Lenders receives from the Borrower which is designated proprietary or
confidential at the time of receipt thereof by such Lender shall not
be disclosed by such Lender to any other Person, if such information
is not otherwise in the public domain, other than (i) to its
independent accountants and legal counsel, (ii) pursuant to statutory
and regulatory requirements, (iii) pursuant to any mandatory court
order, or (iv) to any other Lender or, subject to an agreement
containing provisions substantially the same as those of this Section,
to any participant in or assignee of, or prospective participant in or
assignee of, any Loan.
     SECTION 9.10.  NEW YORK LAW.  This Agreement and each Note shall
be construed in accordance with and governed by the law of the State
of New York.

     SECTION 9.11.  COUNTERPARTS; EFFECTIVENESS.  This Agreement may
be signed in any number of counterparts, each of which shall be an
original, with the same effect as if the signatures thereto and hereto
were upon the same instrument. This Agreement shall become effective
when the Agent shall have received counterparts hereof signed by all
of the parties hereto.

     SECTION 9.12. NON-RECOURSE TO PARTNERS.  No recourse shall be had
for the payment of the principal of or interest on any Loan, or for
any claim based thereon, or otherwise in respect thereof, or with
respect to any other obligation hereunder, against any past, present
or future partner of the Borrower or any partner thereof (including,
without limitation, Santa Fe Pacific Exploration and Santa Fe Energy),
and in no event shall any such Person be held liable, personally or
otherwise with respect to the indebtedness evidenced by the Notes or
for any obligations under this Agreement, whether by virtue of any
statute or rule of law, or

                                 -66-
<PAGE>

by the enforcement of any assessment or penalty or otherwise, all such
liability being expressly waived and released by the Agent and each
Lender.

     IN WITNESS WHEREOF, the parties hereto have caused this Agreement
to be duly executed by their respective authorized officers as of the
day and year first above written.

       also provide Highly Paid Employees the opportunity to receive a

       compensation in excess of that which is covered under the
       Company's Savings Plan.

II.    EFFECTIVE DATE

       Except as provided in Section XIV, the Plan became effective as

IV.    PARTICIPANTS

       Each member of the Board of Directors and each Eligible
       Employee,
<PAGE>
       including each Highly Paid Employee, shall be eligible to
       participate in the Plan. A Highly Paid Employee shall be
       eligible to make an election with respect to his Compensation
       or his Excess Compensation or both. In the event that an       
       employee makes an election to participate in the Plan for a
       particular year believing such employee is an Eligible Employee
       (or Highly Paid Employee, as the case may be), and it is
       subsequently determined that such employee's Compensation at
       the Entry Date does not exceed ten times the amount specified
       in Section 402(g)(1) (or, with respect to a Highly Paid
       Employee, Section 401(a)(17)) of the Code as adjusted for that
       year, any amounts deferred by such employee under the Plan (or,
       if applicable, Excess Contributions made) for such year shall
       be returned to the employee as soon as practicable and no
       further deferrals (or Excess Contributions, as the case may be)
       shall be made for such employee with respect to such year.

V.     MANNER OF ELECTING DEFERRALS

       An Eligible Employee may elect to defer all or a part of his or
       her Compensation for a specified year by giving written notice
       to the Company setting forth the Participant's election as to:

           (a) the percentage (in multiples of 5% of Compensation, up
               to 100% thereof) of the Participant's Compensation to
               be deferred for such year; and

           (b) the Payment Date, as described in Section VII(A), for
               distribution of that year's Deferral Account.

       In addition, a Highly Paid Employee, who has made an election
       under the Savings Plan to contribute the maximum amount
       permitted under Section 402(g)(1) of the Code for that year,
       may elect, either in lieu of or in addition to an election made
       with respect to his Compensation, to defer part of his Excess
       Compensation for such year (an "Excess Contribution") by giving
       written notice to the Company setting forth the Participant's
       election as to:

           (x) the percentage (either 1%, 2%, 3% or 4%) of the
<PAGE>
               Participant's Excess Compensation to be deferred for
               such year; and

           (y) the Payment Date, as described in Section VII(A), for
               distribution of that year's Matching Account and Excess
               Account.

       If, however, during a year a Highly Paid Employee reduces his
       election under the Savings Plan to less than the maximum amount
       permitted by Section 402(g)(1) of the Code, the Participant
       shall automatically cease making Excess Contributions
       thereunder.

       In order to participate in the Plan for a specified year, a
       Participant must deliver an executed deferred compensation
       election to the Company, on the form prescribed by the Company
       for that purpose, prior to the Entry Date for such year.

       The elections described in this Section shall pertain only to
       the year for which they are made and shall apply to all
       Compensation and/or Excess Compensation, if applicable, payable
       for such year. If no election is made for a year, no elective
       deferral of Compensation or Excess Compensation will be made
       for such year. All elections shall be irrevocable except to the
       extent the Committee, in its sole discretion, permits a
       Participant to terminate or change a deferral election. Such
       termination or change shall be effective only with respect to
       Compensation or Excess Compensation earned after the date such
       termination or change of election is approved by the Committee.

VI.    ACCOUNTS

       A.  DEFERRAL ACCOUNTS.  A separate Deferral Account shall be
           established and maintained for each Eligible Employee who
           elects to be a Participant for a year reflecting the amount
           of Compensation electively deferred for that year by the
           Participant and the interest credited thereon as provided
           in D. below. In the event two or more Deferral Accounts of
           a Participant are to be paid on the same Payment Date, all
           such Deferral Accounts shall be aggregated into a single
           Deferral Account for such Participant. At the end of each
           month, an

<PAGE>

           amount shall be credited to the appropriate Deferral
           Account of each Participant to reflect the Compensation
           otherwise payable during said month but deferred pursuant
           to the Plan by the Participant.

       B.  EXCESS ACCOUNTS. A separate Excess Account shall be
           established and maintained for each Highly Paid Employee
           who elects to be a Participant for a year reflecting the
           amount of Excess Compensation electively deferred for that
           year by the Participant and the interest credited thereon
           as provided in D. below. In the event two or more Excess
           Accounts of a Participant are to be paid on the same
           Payment Date, all such Excess Accounts shall be aggregated
           into a single Excess Account for such Participant. At the
           end of each month, an amount shall be credited to the
           appropriate Excess Account of each Participant to reflect
           the Excess Compensation otherwise payable during said month
           but deferred pursuant to the Plan by the Participant.

       C.  COMPANY ACCOUNTS. A separate Company Account shall be
           established and maintained each year for each Highly Paid
           Employee who makes an Excess Contribution such year
           reflecting the amount of Company Matching Contributions
           credited on his behalf that year, if any, and the interest
           credited thereon as provided in D. below. In the event two
           or more Company Accounts of a Participant are to be paid on
           the same Payment Date, all such Company Accounts shall be
           aggregated into a single Company Account for such
           Participant. At the end of each month, an amount shall be
           credited to the appropriate Company Account of each
           Participant who is a Highly Paid Employee to reflect the
           Company Matching Contribution, if any, credited for said
           month on behalf of the Participant.

       D.  INTEREST. Each Account shall be credited with interest as
           of the last day of each month based upon the balance in
           such Account on such date after first reducing the Account
           balance to reflect any distributions made during such month
           from such Account and before crediting to the Account any
           new deferrals made or Company Matching Contributions
           credited, as the case may be,

<PAGE>

           for such month. Interest for each month shall be computed
           by using the interest rate earned for such month by the
           Fixed Interest Fund of the Savings Plan.

       E.  VESTING. A Participant shall at all times be 100% vested
           (possess a nonforfeitable interest) in his Participant and
           Excess Accounts and shall be vested in his Company           
           Accounts, if any, on any date to the same extent that he is
           vested in his Employers Contributions Account under the
           Savings Plan on such date.

VII. DISTRIBUTION OF ACCOUNTS

       A.  ELECTED DISTRIBUTION DATE. Except as provided below, a
           Participant's Accounts shall be valued as of the end of the
           month coinciding with or immediately preceding the Payment
           Date elected by the Participant with respect to such
           Account and shall be paid in a single, lump-sum
           distribution (by Company check) to the Participant as soon
           as is reasonably practicable after such Payment Date.

           Each year a Participant elects to defer Compensation and/or
           Excess Compensation, the Participant shall elect (at the
           time of the deferral and prior to the Entry Date) from
           among the following alternatives (to the extent applicable)
           the Payment Date applicable with respect to his deferrals
           for such year:

               OPTION 1: January 1 of any specified year, but not
                         later than the January 1 on or next following
                         (i) with respect to an Eligible Employee, the
                         later of the Participant's (a) 70th birthday
                         or (b) termination of his employment with the
                         Company and its Subsidiaries or (ii) the
                         Participant's ceasing to be a director, as
                         the case may be;

               OPTION 2: If an Eligible Employee, as soon as
                         practicable after the Participant's
                         "Retirement Date" under the Santa Fe Energy
                         Resources Retirement Income Plan 
<PAGE>

                         (the "Pension Plan");

               OPTION 3: If an Eligible Employee, January 1 after the
                         year in which the Participant's "Retirement
                         Date" under the Pension Plan occurs; or

               OPTION 4: If an Eligible Employee, one month prior to
                         the Participant's "Retirement Date" under the
                         Pension Plan.

       B.  DISTRIBUTION UPON DEATH OR DISABILITY OF PARTICIPANT. If a
           Participant dies or becomes disabled (I.E., is receiving
           benefits under the Company's long-term disability plan or
           Social Security), the Participant's Accounts shall be
           valued as of the end of the month in which the Participant
           dies or becomes disabled, as the case may be, and shall be
           paid to the Participant's estate, in the event of death, or
           to the Participant, in the event of his disability, as the
           case may be, in a single lump-sum (by Company check) as
           soon as is reasonably practicable after such date of death
           or disability.

       C.  EARLY TERMINATION OF EMPLOYMENT. If a Participant
           terminates employment (for reasons other than death or
           Disability) with the Company and its Subsidiaries prior to
           attaining his early retirement date under the Pension Plan,
           then notwithstanding his election of a later Payment Date
           to the contrary, his Accounts shall be valued as of the end
           of the month coinciding with or immediately preceding the
           date of such termination of employment and, to the extent           
           vested, shall be paid to the Participant in a single
           lump-sum (by Company check) as soon as is reasonably
           practicable thereafter. Any nonvested Company Account
           balances shall be immediately forfeited on his termination
           of employment.

       D.  HARDSHIP DISTRIBUTIONS. In the event of an unforeseen and
           immediate financial emergency of a Participant which is
           beyond his control, the Committee may, in its sole
           discretion, upon a written request of a participant, direct
           the acceleration of such vested portion of the
           Participant's Accounts as may be
<PAGE>

           necessary to meet such emergency. The Committee shall
           require the Participant to furnish the Committee with proof
           of such emergency and the Participant's other financial
           resources as the Committee may deem necessary to evaluate a
           Participant's written request for accelerated payment.

VIII.  PARTICIPANTS' RIGHT

       Establishment of the Plan shall not be construed to give any
       Eligible Employee the right to be retained in the service of
       the Company or a Subsidiary. A Participant shall not have any
       interest in the amounts credited to his Accounts until such
       Accounts are distributed in accordance with the Plan. With
       respect to amounts deferred or otherwise held in an Account for
       a Participant, the Participant shall be an unsecured general
       creditor of the Company.

IX.    NON-ALIENABILITY AND NON-TRANSFERABILITY

       No Participant may borrow against his Accounts; no Account
       shall be subject in any manner to anticipation, alienation,
       sale, transfer, assignment, pledge, encumbrance, charge,
       garnishment, execution or levy of any kind, whether voluntary
       or involuntary. However, if a former spouse of a Participant is
       awarded an interest in a Participant's Accounts through a
       judgment or order of a court, the Committee may, in its sole
       discretion, direct that the payment of such interest awarded to
       the former spouse be paid (valued as of the end of the month
       that the Company received written notice of such award) to the
       former spouse in a lump sum; thereafter, the Participant's
       Accounts shall be reduced for all Plan purposes by the amount
       of any such payment.

X.     STATEMENT OF ACCOUNT

       Statements will be sent to Participants as soon as practicable
       after the end of each year as to the balance in their Accounts
       as of the end of such year.

XI.    ADMINISTRATION

<PAGE>

       The Committee shall have the authority to adopt rules and
       regulations for carrying out the Plan and to interpret,
       construe and implement the provisions thereof. Any decision or
       interpretation of any provision of the Plan adopted by the
       Committee shall be final and conclusive. The individuals
       serving as the Committee shall be fully indemnified (to the
       extent permitted by law) by the Company for all claims, losses,
       damages or expenses incurred by them for any act, omission or
       construction made in connection with the Plan. The Committee is       
       expressly authorized to direct at any time that the Accounts of
       a Participant that are fully vested and payable at the same
       Payment Date be aggregated for recordkeeping purposes.

XII.   AMENDMENT AND TERMINATION

       The Plan may, at any time, be amended, modified or terminated
       by the Board of Directors. In addition, the Committee may amend
       or modify the Plan provided that no such amendment or
       modification made by the Committee can materially increase the
       obligations of the Company under the Plan. Any such amendment,
       modification or termination requires the affirmative approval
       of a majority of the members constituting a quorum and shall be
       evidenced by a written resolution or other document signed by
       the Board of Directors or the Committee, as the case may be. No
       amendment, modification or termination of the Plan shall,
       without the consent of a Participant, adversely affect such
       Participant's rights with respect to amounts accrued in his
       Accounts. Notwithstanding anything in the Plan to the contrary,
       all Accounts shall become immediately payable in full upon the
       termination of the Plan.

XIII.  UNFUNDED STATUS OF THE PLAN

       Except as provided below, any and all payments made to the
       Participant pursuant to the Plan shall be made only from the
       general assets of the Company. All Accounts under the Plan
       shall be for bookkeeping purposes only and shall not represent
       a claim against specific assets of the Company. Nothing
       contained in this Plan shall be deemed to create a trust of any
       kind or create any fiduciary relationship between the Company
       and the Participant. The Company, in its sole discretion, may
       establish a grantor trust to provide for all or part of such
       Accounts, provided that the assets

<PAGE>

       of such grantor trust at all times remain subject to the claims
       of the general creditors of the Company.

XIV.   SFP PLAN TRANSFERRED ACCOUNTS

       Effective with the corporate spinoff of the Company by Santa Fe
       Pacific Corporation ("SFP") the deferred accounts of any
       Eligible Employee under a similar SFP deferred compensation
       plan were transferred from such SFP plan to this Plan and such
       transferred accounts shall continue to be held hereunder
       pursuant to the elections made by the Participants under the
       SFP plan and shall be invested as provided in this Plan and
       paid pursuant to the Participant's distribution election(s)
       made under the SFP plan. Further, any deferral election made
       under such SFP plan with respect to compensation otherwise to
       be earned by the Eligible Employee after the date of the
       corporate spinoff shall be deemed to be a continuing election,
       without interruption or change, under this Plan for the
       remainder of the year in which such corporate spinoff occurs.

XV.    GENERAL PROVISIONS

       A.  NOTICES. All notices to the Company hereunder shall be
           delivered to the attention of the Secretary of the Company.

           shown on the postmark or the receipt for registration or
           certification.

       B.  CONTROLLING LAW. Except to the extent superseded by

           shall be controlling in all matters relating to the Plan.

           the Company under the Plan shall be by resolution of its
           Board of Directors or any person or persons authorized by
           its Board of Directors with respect to such matters. 

       E.  FACILITY OF PAYMENT. Any amounts payable hereunder to any
           person under legal disability or who, in the judgment of
           the Committee, is unable to properly manage his financial
           affairs may be paid to the legal representative of such

           any manner which the Committee may select.

       F.  WITHHOLDING OF TAXES. The Company shall withhold from such
           Compensation and Excess Compensation when deferred, or from

           case may be, any taxes required to be withheld therefrom
           for federal, state or local government purposes.

       G.  SEVERABILITY. Whenever possible, each provision of the Plan
           shall be interpreted in such manner as to be effective and
           valid under applicable law (including the Code), but if any
           provision of the Plan shall be held to be prohibited by or
           invalid under applicable law, then (i) such provision shall
           be deemed amended to, and to have contained from the outset

           objectives of the provision and (ii) all other provisions
           of the Plan shall remain in full force and effect.

           or procedure established by the Committee.

       I.  SUCCESSORS. The provisions of the Plan shall bind and inure

quantities of Seller's Gas, Seller shall give Buyer notice as soon as
reasonably practicable under the circumstances.  Each curtailment
notice shall be in writing and shall identify the quantities of
Seller's Gas that Seller intends to curtail or shut-in and the
expected duration of such curtailment or shut-in period.  Seller shall
not, however, shut in or
                                  -6-
<PAGE>

curtail any quantities of Seller's Gas solely for inadequate price
during any Month in which such quantities of Seller's Gas have been
represented as being available for sale to Buyer in Seller's Estimate
given three (3) Days prior to Buyer's Transporter's nomination
deadline for such Month. If Seller returns to production during the
middle of any Month any quantities of Seller's Gas shut-in or
curtailed due to inadequate price, Seller shall give prior written
notice to Buyer and Buyer shall have the right, but not the
obligation, to purchase such Seller's Gas for the balance of such
Month at the gas price determined under Section 8.4.  If Buyer elects
to not purchase such Seller's Gas for the balance of such Month,
Seller may sell such Seller's Gas not purchased by Buyer to any third
party.  At the end of such Month, Buyer shall resume purchasing under
the terms of this Agreement all such Seller's Gas nominated under
Section 4.1.

    2.5   PROCESSING OF GAS.  Seller reserves the right to process
Seller's Gas either prior to the Delivery Points or after delivery to
Buyer at the Delivery Points.  Seller's Gas may be processed to
extract liquid and liquefiable hydrocarbons, together with any methane
unavoidably contained in the ethane or heavier hydrocarbons.  Such
processing will not render the total heating value to be less than the
requirements of the transporter or otherwise cause Seller's Gas to not
meet the quality specifications of the transporter.  All liquid and
liquefiable hydrocarbons so recovered shall belong to Seller.  If
Seller's Gas is processed by Seller after delivery to the Delivery
Points, Seller shall be paid by Buyer for the volumes of residue gas
remaining after processing and Seller shall be responsible for charges
of Buyer's Transporter for the transportation to the processing plant
of fuel and plant volume reduction resulting from such processing.  If
Seller's Gas is processed under percentage of proceeds-type contracts
or other agreements that do not provide for the residue gas
attributable to Seller's Gas to be returned in kind at the tailgate of
the processing plant, Buyer shall
                                  -7-
<PAGE>

release such Seller's Gas from this Agreement in writing upon written
request by Seller.  

    2.6   RELEASE OF CERTAIN PROPERTIES.  Buyer shall, if requested by
Seller, promptly release from commitment and dedication hereunder all
Seller's Gas produced from any Seller's Wells if (i) Seller commits to
sell or exchange such Seller's Wells under a written agreement with a
third party which is not an affiliate of Seller and (ii) under such
agreement the average amount of the consideration to be received by
Seller for the gas reserves attributable to Seller's interests in each
such Seller's Well is less than  $250,000 per Seller's Well.  If Seller
desires to sell to a third party and have released from this Agreement
any Seller's Wells that do not meet the requirements of the preceding
sentence, Seller may substitute for such Seller's Wells like
quantities of gas delivered to delivery points reasonably acceptable
to Buyer and with daily deliverabilities during the term of this
Agreement similar to the Seller's Wells which Seller proposes to sell. 
Buyer shall release from commitment under this Agreement such Seller's
Wells effective as of the date such substitute wells become subject to
this Agreement.

    2.7   RELEASE OF CERTAIN NONOPERATED WELLS.  If the Imbalance
Penalties paid or incurred by Seller under this Agreement for any
Seller's Gas produced from any nonoperated Seller's Well become
excessive in Seller's reasonable opinion, Buyer shall, upon written
request by Seller, release such Seller's Gas from commitment under
this Agreement unless Buyer agrees to be responsible for and bear such
Imbalance Penalties for such Seller's Well.  

    2.8   OPERATIONAL RESERVATIONS.  Seller hereby reserves and
excepts the following rights and quantities of Seller's Gas from the
provisions of this Agreement:

    (i)   The right to use Seller's Gas produced from any lease or
    field for Seller's requirements in the development and operation
    of such leases and fields including, but not limited to, use of
    Seller's Gas for drilling, enhanced recovery

                                  -8-
<PAGE>
    operations, workover operations, treating, gas lifting oil wells
    for repressuring, recycling, or pressure maintenance purposes,    
    and compressor fuel, and to otherwise operate such leases and
    fields free from any control by Buyer.  Subject to Section 2.9,
    Seller will not, however, use any Seller's Gas for enhanced oil
    recovery operations in California other than Seller's Gas that is
    produced in California.  

    (ii)  Seller's Gas which is delivered to others under Seller's
    leases, Seller's agreements for easements, unit agreements, unit
    operating agreements, operating agreements, or other similar
    agreements affecting Seller's Wells.

    (iii)    All liquids, liquid hydrocarbons, oil, and condensate
    removed from Seller's Gas prior to the Delivery Points.

    (iv)  The right to pool or unitize Seller's leases with other
    leases of Seller or others located in the field in which Seller's
    Wells are located.  

    (v)   The right to operate Seller's leases and Seller's Wells in
    such manner as Seller, in Seller's discretion, deems advisable,
    including the right to drill new wells, to rework Seller's Wells,
    to renew in whole or in part any leases, and to abandon any
    Seller's Well or surrender, release, or terminate any lease, in
    Seller's discretion.

    (vi)  Seller's Gas delivered to others under gas balancing
    agreements or similar arrangements affecting any of Seller's
    Wells.

    2.9   EOR OPERATIONS.  At any time after twenty-four (24) Months
after the Effective Date and upon forty-five (45) Days' prior written
notice from Seller, Buyer shall release from commitment under this
Agreement up to 30,000 MMBtu's per Day of Seller's Gas for use by
Seller in Seller's enhanced oil recovery operations in California or
in exchange for other gas to be used in such operations ("EOR Gas"). 
Buyer shall, at the request of Seller, arrange for the transportation
of EOR Gas from the Delivery Points to Seller's enhanced oil recovery
operations in California using
                                  -9-
<PAGE>

either Seller's transportation rights or Buyer's transportation
rights, as directed by Seller.  Seller shall be responsible for
transportation charges to transport EOR Gas to its enhanced oil
recovery operations in California.  In consideration of Buyer
releasing and arranging such transportation for EOR Gas, Seller shall
pay Buyer each Month a handling fee of five cents (5 cents) for each MMBtu
released under this Section 2.9.  EOR Gas shall become recommitted to
this Agreement on the first day of the Month following the date Seller
permanently ceases to use EOR Gas in its California enhanced oil
recovery operations.  Seller shall give Buyer at least fifteen (15)
Days' notice prior to the first day of the Month in which EOR Gas will
become recommitted to this Agreement.

    2.10  ACQUISITION PROPERTIES.  Buyer recognizes that all gas
produced from wells or properties acquired by Seller after the
Effective Date in connection with or as part of the acquisition or
purchase of producing oil and gas properties shall not be subject to
or committed to this Agreement.

    2.11  PREEXISTING CONTRACTS.  Upon the expiration of or
termination of any Preexisting Contract, any Seller's Gas subject to
or covered by such Preexisting Contract shall become committed to this
Agreement without further action of the Parties.  Buyer shall notify
Seller in writing no less than thirty (30) Days before the date each
Preexisting Contract expires or terminates based on the information in
Exhibit C.  If Buyer timely gives Seller such notice, Seller will
exercise its rights to terminate each Preexisting Contract at the end
of its primary term unless the failure to extend the term of any such
Preexisting Contract would cause Seller to pay penalties or to
otherwise incur any costs or expenses for failing to extend the term
of such Preexisting Contract.  Seller shall not, however, have any
obligation to Buyer, and this provision does not create any obligation
upon Seller, to cause the early termination or expiration of any
Preexisting Contract.  
                                 -10-
<PAGE>
    2.12  POWER TEX CONTRACT.  Buyer shall, for a period ending not
later than twenty-four (24) Months after the Effective Date and upon
not less than ten (10) days' prior written notice by Seller, release
from commitment under this Agreement up to 4,500 MMBtu's per Day of
Seller's Gas to allow Seller to supply gas under that certain Gas
Sales Agreement between Adobe Gas Marketing Co. and the City of
Lubbock, dated May 9, 1991 (the "Power Tex Contract").  Any such
released Seller's Gas shall become recommitted to this Agreement at
the beginning of the first Month following the end such twenty-four
(24) Month period.

                               ARTICLE 3
                               QUANTITY

    3.1   PURCHASE AND SALE OBLIGATION.  Commencing on the Effective
Date and continuing through the term hereof, Seller agrees, subject to
the other provisions hereof, to sell and deliver, or cause to be
delivered and sold, to Buyer at the Delivery Points the quantity of
Seller's Gas nominated each Month by Seller under Article 4.  Seller
shall use its reasonable efforts to deliver the gas at uniform hourly
and daily rates of flow.  Buyer agrees to take and purchase all of
Seller's Gas delivered each Month at the Delivery Points.

    3.2   FAILURE TO DELIVER OR TAKE.  If for any reason other than
Force Majeure either Party fails in any Month to perform its
obligation to deliver or take Seller's Gas under this Agreement, the
other Party shall use its reasonable efforts to mitigate the effect of
such failure to perform, which includes attempting to secure an
alternate interruptible supply or interruptible market, as the case
may be, at reasonable prices.

    3.3   PARTIAL MONTHLY PRODUCTION.  If Seller delivers to any
Delivery Point after the first day of any Month any quantity of
Seller's Gas that was not previously delivered at any time in such
Month due to Force Majeure affecting Seller or that is

                                 -11-
<PAGE>

attributable to the recompletion of an Existing Well or the completion
or recompletion of any Development Well or Exploration Well, Buyer
shall have the obligation to take and purchase such Seller's Gas
during such Month, but only to the extent Buyer is able to arrange
transportation for such Seller's Gas in such Month.  If Buyer is
unable to arrange transportation for such Seller's Gas in such Month,
Seller may sell such Seller's Gas to any third parties during such
Month.  

                               ARTICLE 4
            SCHEDULING AND TRANSPORTATION OF DAILY VOLUMES

    4.1 GAS SCHEDULING.  At least three (3) Days prior to Buyer's
Transporter's nomination deadline for the first Day of the following
Month, Seller shall provide Buyer a written report by telecopy showing
Seller's Estimate for each Delivery Point for the following Month. 
Seller shall use its reasonable efforts to provide along with Seller's
Estimate for each Month a description of any planned or foreseeable
events which will materially affect deliveries during the following
Month, including workovers and new Seller's Wells beginning
production.  If the quantity of Seller's Gas delivered to one or more
Delivery Points differs from Seller's Estimate by more than the
transporter's tolerance level for such Delivery Points for any Day or
Days, Seller shall so notify Buyer immediately after becoming aware of
such change by telephone, and shall provide Buyer with a revised
written Seller's Estimate for such Delivery Points for the remainder
of the Month by telecopy as soon as reasonably practicable.  As of the
Effective Date, Buyer shall notify Seller in writing of the Daily and
Monthly tolerance levels for Imbalance Penalties for each transporter
for each Delivery Point.  Such tolerance levels shall remain in effect
until Seller is otherwise notified by Buyer.

                                 -12-
<PAGE>
    4.2 TRANSPORTATION CAPACITY.  Buyer shall arrange for and
maintain all necessary transportation downstream of the Delivery
Points to ensure that Seller's Gas flows without interruption, except
in the case of Force Majeure.  

    4.3 TRANSPORTATION IMBALANCES.  

        (a)  AVOIDANCE.  Buyer and Seller shall use all reasonable
    efforts to avoid the imposition of Daily or Monthly Imbalance
    Penalties by any transporter and each Party agrees to cooperate
    with the other Party to resolve and eliminate, to the extent
    reasonably practicable, any Imbalance Penalties.

        (b)  RESPONSIBILITY.  If any Imbalance Penalties are incurred
    or payable to a transporter with respect to Seller's Gas
    delivered to any Delivery Point as a result of Seller's actions,
    including Seller's failure to give Buyer timely notice of any
    increase or decrease in Daily quantities to be delivered at such
    Delivery Point from Seller's Estimate for such Delivery Point,
    Seller shall be responsible for such Imbalance Penalties.  If any
    Imbalance Penalties are incurred or payable to a transporter with
    respect to Seller's Gas delivered to any Delivery Point as a
    result of Buyer's actions, including Buyer's failure to give
    timely notice to such transporter of any change in Seller's
    Estimate for such Delivery Point after receiving timely notice
    from Seller of such change, Buyer shall be responsible for such
    Imbalance Penalties.

        (c)  TIMELY NOTICE.  For the purpose of this Section 4.3,
    Seller's notice will be deemed timely if, under the
    circumstances, it gives Buyer reasonably sufficient time to
    notify the transporter of such changes to Seller's Estimate by
    the time required under the terms of such transporter's Tariff to
    avoid the imposition of such Imbalance Penalties.

        (d)  SELLER'S CREDIT.  In determining the amount of any
    Imbalance Penalties due by Seller hereunder in any Month, Buyer
    shall aggregate the Cashout Costs for which Seller is responsible
    and which were incurred by Buyer
                                 -13-
<PAGE>
    for all  transporters for such Month.  Buyer shall, for each such
    Month, credit all such Cashout Costs that resulted in Buyer
    selling gas at a price higher than the applicable Index Price or
    that resulted in Buyer buying gas at a price lower than the
    applicable Index Price ("Buyer's Monthly Gain") against all such
    Cashout Costs that resulted in Buyer buying gas at a price higher
    than the applicable Index Price or that resulted in Buyer selling    
    gas at a price lower than the applicable Index Price ("Buyer's
    Monthly Loss") to arrive at an aggregate net Imbalance Penalty
    for such Month.  If, for any Month, Buyer's Monthly Gain for such
    Month exceeds Buyer's Monthly Loss for such Month, Buyer shall
    have no obligation to refund the difference to Seller.

        (e)  BUYER'S CREDIT.  In determining the amount of any
    Imbalance Penalties due by Buyer hereunder, Seller shall
    aggregate all Cashout Costs for which Buyer is responsible and
    which were incurred by Seller in any Month under operational
    balancing agreements, operating agreements, or other agreements
    covering any Seller's Well.  Seller shall, for each such Month,
    credit all such Cashout Costs that resulted in Seller selling gas
    at a price higher than the applicable Index Price ("Seller's
    Monthly Gain") against all such Cashout Costs that resulted in
    Seller selling gas at a price lower than the applicable Index Price
    or that resulted from Seller buying gas ("Seller's Monthly Loss")
    to arrive at an aggregate net Imbalance Penalty for such Month. 
    If, for any Month, Seller's Monthly Gain exceeds Seller's Monthly
    Loss, Seller shall have no obligation to refund the difference to
    Buyer.

        (f)  LLANO SYSTEM.  Seller shall not be responsible for any
    Imbalance Penalties for Seller's Gas gathered on the Llano
    System.

        (g)  NO LIMIT.  The provisions of this Section 4.3 do not in
    any way waive, limit, or alter either Party's obligation under
    Section 3.1.
                                 -14-
<PAGE>
    4.4 ASSIGNMENT OF GATHERING CONTRACTS.  As of the Effective Date,
Seller shall assign to Buyer, to the extent Seller has the contractual
right to do so, any agreements entered into prior to the Effective
Date with third parties for the gathering of Seller's Gas.  If Seller
is required to obtain the consent or approval of any third party to
assign any or all of such agreements to Buyer, Seller shall use its
reasonable efforts to obtain any and all third-party consents and
approvals as quickly as reasonably practicable.  If Seller does not
have the legal right to assign any such agreement, then Seller shall
authorize Buyer to act as Seller's agent under such agreements.  Buyer
shall administer all such agreements so that they remain valid and
enforceable in accordance with their terms.  Buyer shall obtain the
consent of Seller prior to releasing, amending, or otherwise modifying
such agreements.  Upon termination or expiration of this Agreement,
Buyer shall reassign to Seller or its designee all such agreements
that remain in effect.

    4.5 DELIVERY POINTS.  As of the Effective Date, Buyer and Seller
have agreed that Seller's Gas will be delivered and accepted at the
Delivery Points described in Exhibit A.  The parties shall mutually
agree to the Delivery Point for each Development Well or Exploration
Well which subsequently produces Seller's Gas subject to this
Agreement and the Parties may at any time otherwise agree to change,
add to, or delete from the Delivery Points shown in Exhibit A.  Any
supplement or amendment to Exhibit A shall be in writing and executed
by both Parties.

    4.6 DELIVERY DIFFERENCES.  If at the end of the first six (6)
Months of this Agreement, the aggregate quantity of Seller's Gas
delivered by Buyer for each Month to any interstate pipeline has been
materially different from Seller's Estimate for such Seller's Gas made
by Seller three (3) Days prior to the nomination deadline of the
applicable Buyer's Transporter for each such Month, except as allowed
under the provisions of this Agreement, Seller shall, upon Buyer's
written request, use all reasonable efforts to promptly correct such
differences in the following two (2)

                                 -15-
<PAGE>

Months.  If Seller fails to correct such differences in the following
two (2) Months, Buyer may request the renegotiation of Buyer's payment
hereunder of the Index Price for such differences and allocation among
the Parties of any benefits or costs to Buyer arising out of such
differences for the remaining term of this Agreement.  If Buyer and
Seller are unable to mutually agree on the price to be paid for such
differences and such allocation, such matter may be submitted by
either Party to Arbitration as a Dispute under Article 9.

                              ARTICLE 5 
                           BUYER'S SERVICES

    5.1 CONNECTION OF GATHERING SYSTEMS - EXPLORATION WELLS.  Within
thirty (30) Days of the drilling and completion of any well producing
commercial quantities of gas on the Exploration Lands, Seller shall
notify Buyer of the completion of such well and provide Buyer with all
available well test data including, without limitation, all well logs,
drill stem tests, well potential tests, and Seller's estimate of well
deliverability and ultimate recoverable reserves.  Within twenty (20)
Days after receipt of Seller's notice, Buyer shall submit to Seller,
in writing, for Seller's review, Buyer's recommendation of the most
economical and efficient method of gathering and transporting the gas
produced from such well, whether by Buyer, Seller, or third parties
("Buyer's Gathering Proposal").  Seller may, in its discretion, either
accept or reject Buyer's Gathering Proposal by giving written notice
to Buyer.  If Seller accepts Buyer's Gathering Proposal, Buyer shall
promptly commence and diligently complete the work necessary to
implement Buyer's Gathering Proposal, and, upon completion of such
gathering system, Seller will sell the gas produced from such well to
either Buyer or a third party, as provided in Buyer's Gathering
Proposal.  If the gas produced from such well is sold to Buyer under
this Agreement, such well shall become committed to this Agreement as
an Exploration Well.  If Seller rejects

                                 -16-
<PAGE>

Buyer's Gathering Proposal, Seller may contract with any third parties
to gather and purchase the gas produced from such well without any
obligation to Buyer under this Agreement.  

    5.2 DEVELOPMENT WELLS.  Upon completion of each Development Well,
Buyer shall, if requested by Seller, recommend the most economical
method of gathering the gas produced from such Development Well.

    5.3 MARKETING UPDATES.  Buyer shall, upon request, provide Seller
written updates and verbal briefings on gas market trends including,
but not limited to, the development of new natural gas markets or
expansion of existing markets, changes in the relative wellhead values
of gas in different regions of the country due to the construction of
new pipelines or other developments, and supply and demand forecasts. 
In addition, Buyer shall periodically provide written updates on
regulatory trends and developments in both the domestic and
international gas market that could impact Seller.

    5.4 SUPPLY OF GAS UNDER POWER TEX CONTRACT.  Upon request by
Seller, during the first twenty-four (24) Months of this Agreement,
Buyer will, as agent for Seller, purchase and deliver the gas required
to be delivered under the Power Tex Contract upon terms mutually
acceptable to Buyer and Seller.                               
                               
                               ARTICLE 6
                        QUALITY AND MEASUREMENT

    6.1 BUYER'S TRANSPORTER.  The rules, guidelines, and policies of
Buyer's Transporter, as may be changed from time to time, shall govern
the units of measurement, measurement specifications, quality, heating
value, and testing specifications of Seller's Gas delivered to each
Delivery Point.  

    6.2 QUALITY.  Seller's Gas shall meet the quality specifications
of Buyer's Transporter at each Delivery Point.  If all or any portion
of the Seller's Gas does not
                                 -17-
<PAGE>

meet the quality specifications of Buyer's Transporter, Buyer at its
option may at any time refuse to accept any or all such Seller's Gas
("Subquality Gas").  Acceptance of any or all Subquality Gas that
fails to conform to the quality specifications of this Agreement shall
not be deemed a waiver of Seller's obligations hereunder with respect
to such Subquality Gas or with respect to any future deliveries of
Subquality Gas.  All Subquality Gas which Buyer fails to take under
this Section 6.2 may be sold to any third parties free from any
obligation under this Agreement during the period Buyer refuses to
accept such Subquality Gas.  SELLER MAKES NO OTHER WARRANTIES,
EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, INCLUDING WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, ABOUT SELLER'S
GAS.  

                               ARTICLE 7
                         OWNERSHIP AND CONTROL

    7.1 DELIVERY.  Gas sold and delivered hereunder shall be
delivered by Seller to Buyer at the Delivery Points.  Title and risk
of loss to all Seller's Gas shall pass from Seller to Buyer at the
Delivery Points.  If Seller elects under Section 2.5 to process any
quantities of Seller's Gas after the Delivery Points, the risk of loss
for such Seller's Gas shall pass from Buyer to Seller where such
Seller's Gas enters the facilities of the party processing such
Seller's Gas.  The risk of loss to the residue gas resulting from
processing such Seller's Gas shall pass to Buyer where it enters the
facilities of Buyer's transporter at or near the tailgate of such
processing facilities.

    7.2 CONTROL.  As between the Parties hereto, Seller shall be
deemed to be in control and possession of Seller's Gas and shall be
fully responsible for and shall defend and indemnify Buyer, its
successors and assigns, against any damages or injury resulting from
the operation of facilities used to deliver gas at the Delivery
Points, or the possession and handling of such Seller's Gas, until
delivered to Buyer or
                                 -18-
<PAGE>

Buyer's Transporter at the Delivery Points and during the period such
Seller's Gas, if processed, is in the facilities of the processor. 
Except as provided in the preceding sentence, Buyer shall be deemed to
be in control of Seller's Gas and shall be responsible for and shall
defend and indemnify Seller, its successors and assigns, against any
and all damages or injury resulting from the transportation, handling,
or use of Seller's Gas after it is delivered to Buyer, or Buyer's
Transporter, at the Delivery Points.

                                 PRICE

    8.1 MONTHLY GAS PRICES.  Except as otherwise provided in this
Article 8, for all Seller's Gas delivered to each Delivery Point each
Month, Buyer shall pay Seller a gas price per MMBtu equal to the Index
Price for each such Delivery Point for such Month less Transportation
Expenses, if any, for such Seller's Gas for such Month.

    8.2 PRICING COMBINATION.  Buyer shall, for each Month, use its
best efforts to obtain for Seller at each Delivery Point the Index
Price, Pricing Point, and Transportation Expenses for Seller's Gas
delivered to each such Delivery Point in such Month that result in the
highest net back price to Seller under Section 8.1 for such Delivery
Point, giving consideration to and consistent with Buyer's obligation
under Section 3.1 to purchase and take all of Seller's Gas delivered
to each such Delivery Point in such Month.
  
    8.3 DELIVERY.  Subject to the other provisions of this Agreement,
Seller shall be responsible for, and shall pay all costs and expenses
of, all arrangements necessary to deliver Seller's Gas to the Delivery
Points and Buyer shall be responsible for, and shall pay all costs and
expenses of, all arrangements necessary to receive Seller's Gas
delivered hereunder at the Delivery Points.  

                                 -19-
<PAGE>
    8.4 PARTIAL MONTHLY PRODUCTION.  For all Seller's Gas taken by
Buyer at any Delivery Point under Section 3.3 and for all Seller's Gas
returned to production in the middle of a Month under Section 2.4
after being shut-in or curtailed due to inadequate price, the average
of the high and low prices per MMBtu published in the table "Daily
Price Survey" in GAS DAILY for the first Day of deliveries for the
region of production for such Delivery Point shall be substituted for
the Index Price in determining the price to be paid by Buyer to Seller
for such Seller's Gas under Section 8.1.

    8.5 LLANO SYSTEM TRANSPORTATION RATE.  The Transportation
Expenses for Seller's Gas gathered on the Llano System shall never
exceed in any Month the lowest transportation rate charged by Buyer to
other shippers on the Llano System in the prior six (6)-Month period,
except for any such rate which may be agreed to by Llano Inc., in its
discretion, as part of the settlement of any claim made against Llano
Inc. or its affiliates.

    8.6 TRANSPORTATION EXPENSES.  Buyer shall, for each Delivery
Point, use its best efforts each Month to obtain for Seller the lowest
reasonably available transportation rates on Buyer's Transporter for
Seller's Gas, consistent with reliability and giving consideration to
Buyer's obligation to purchase and take all of Seller's Gas at such
Delivery Point and to Seller's right to shut-in or curtail production
of Seller's Gas hereunder.

    8.7 PUBLICATION OF INDEX PRICE.  If INSIDE FERC or any
replacement publication or other information source then in effect to
determine the Index Price ceases to be available, substantially alters
the method by which the referenced prices are calculated, or otherwise
substantially alters the referenced prices, the Parties shall mutually
agree in writing on a replacement publication or information source. 
If the Parties are unable to mutually agree on a replacement
publication or information source, the matter may be submitted by

                              ARBITRATION

    9.1 RESOLUTION OF DISPUTES.  Except as provided in the following
sentence, any action, dispute, claim, or controversy arising between
the Parties under this Agreement (each a "Dispute") shall be resolved
by arbitration ("Arbitration") in accordance with the procedures set
forth below.  Any dispute, claim, or controversy arising under Article
12 shall not be a subject to arbitration under this Article 9.  If a
Dispute is not resolved by the Parties after negotiation among
themselves, either Party may invoke Arbitration by providing written
notice to the other Party of its intent to submit the Dispute to
Arbitration hereunder.  Either Party may bring an action to compel the
Arbitration of any Dispute.

    9.2 SELECTION OF THE ARBITRATOR.  Not later than ten (10) Working
Days following the receipt of notice from either Party notifying the
other Party of its intent to submit a Dispute to Arbitration, Buyer
and Seller shall mutually select and appoint an arbitrator (the
"Arbitrator") to resolve the Dispute.  If at the end of such ten (10)
Working-Day period the Arbitrator has not been selected and appointed,
then each Party shall, within five (5) Working Days, thereafter,
select an arbitrator.  The two arbitrators shall then jointly select a
third arbitrator (each an "Arbitrator") within ten (10) Working Days
after the appointment of the second Arbitrator.  Any Arbitrator acting
hereunder shall be a qualified neutral third party not having any
prior, current, or known or anticipated future affiliation or
association with Seller or Buyer.  If the Dispute involves a pricing
matter hereunder, each Arbitrator shall have a minimum of ten (10)
years' (immediately prior to the appointment) general experience in
the purchase and sale of natural gas.

    9.3 ARBITRATION.  Upon selection and appointment of the
Arbitrators, each Party shall deliver to the other Party and to the
Arbitrators, within ten (10) Working

                                 -21-
<PAGE>

Days of the appointment of the Arbitrators, a written proposal stating
its proposed outcome together with supporting materials and
documentation.  Each Party may submit its written counterproposal
together with supporting materials and documentation, within ten (10)
Working Days of receipt of the written proposal from the other Party,
to both that Party and the Arbitrators.  The Arbitrators may request
additional information or documentation from either Party, which
information or documentation shall be timely provided.  No later than
twenty (20) Working Days after the counterproposals are submitted, the
Arbitrators shall select and adopt either the outcome desired by
Seller or the outcome desired by Buyer, without modification or
compromise.  All Arbitrations shall take place in Houston, Harris
County, Texas.

    9.4 PRICING INSTRUCTIONS.  If the Dispute involves the
determination of the Index Price, the Arbitrators shall be given the
following instructions, unless the Parties agree in writing upon other
instructions:

        (i)      In determining the Index Price, the Arbitrators will
    recognize that the Parties selected INSIDE FERC as representative
    of the fair market value of Seller's Gas at each Pricing Point on
    the Effective Date;  

        (ii)     The Index Price shall be reported on a Monthly basis
    from a publication or other information source publicly
    available; and
        
        (iii)    The Arbitrators shall determine the Index Price by
    selecting either the Index Price proposed by Seller or the Index
    Price proposed by Buyer, without modification or compromise.

    9.5 PRICE PAYABLE DURING ARBITRATION.  If the Dispute relates to
the publication or other information source then being used to
determine the Index Price, the price paid during the Arbitration shall
be determined from such publication or information source or, if such
publication or information source is no longer available, the price
shall be determined from the last such publication or information
source that was
                                 -22-
<PAGE>

available.  Upon the conclusion of the Arbitration, the price paid by
Buyer to Seller for such Seller's Gas shall be adjusted retroactively
to the date the Arbitration was invoked.  The Party owing the other
Party as a result of such retroactive adjustment shall pay to such
other Party the amounts due under the redetermined Index Price within
ten (10) Working Days following the Arbitrator's decision.

    9.6 FINALITY OF AWARD AND COSTS OF ARBITRATION.  The
determination of the Arbitrators shall be final and binding on the
Parties, except in the event of manifest material error or misconduct
by the Arbitrators.  Each Party shall bear its own costs and expenses
and share equally the costs and expenses of the Arbitrators and the
arbitration.

    9.7 SUPPLEMENTAL ARBITRATION RULES.  Each Arbitration shall be
administered in accordance with the terms of this Article 9 and the
Commercial Arbitration Rules of the American Arbitration Association. 
Judgment on any award rendered by the Arbitrators may be entered in
any court having jurisdiction.

purchased and sold hereunder is inclusive of all production,
severance, ad valorem, and/or similar taxes levied on the production
of Seller's Gas prior to the Delivery Points, and all such taxes shall
be borne and paid by Seller.  If state law requires Buyer to remit
such taxes to the collecting authority, then Buyer shall do so and
deduct the taxes so paid on Seller's behalf from payments otherwise
due to Seller hereunder.  Buyer shall pay and be responsible for all
federal, Indian, state or local sales, use, consumption, and/or
similar taxes which may now or hereafter be imposed on the transfer of
title or possession of Seller's Gas.

                                PAYMENT

    11.1     MONTHLY PAYMENT.  Not later than the fifteenth (15th) day
of each Month, Seller shall provide Buyer with a statement setting
forth the volumes of gas delivered at the Delivery Points in the prior
Month along with an invoice for payment based thereon.  If actual
volumes at the Delivery Points are not available by the fifteenth
(15th) day of the Month, Seller may furnish statements and invoices
based on Seller's Estimate.  By no later than the last Working Day of
the Month following the production Month, Buyer shall make payment of
the amount set forth in Seller's statement by wire transfer into
Seller's account in accordance with Seller's instructions.  Buyer
shall submit to Seller with each Monthly payment a schedule showing,
for each Delivery Point for such Month, the quantity of Seller's Gas
delivered to such Delivery Point, the Pricing Point, the Index Price,
and any Transportation Expenses and Imbalance Penalties attributable
to Seller's Gas from such Delivery Point.  If requested by Seller,
payment to Seller hereunder shall be made through a bank or escrow
account established, funded, and maintained in a manner acceptable to
Seller in all respects.  

    11.2     PAYMENT DEFAULT.  If Buyer fails to pay Seller for
Seller's Gas for any Month within three (3) Working Days of the date
required under Section 11.1, Seller may, at its option, either,
singularly or in combination, (i) immediately terminate this
Agreement, or (ii) suspend performance under this Agreement until all
indebtedness under this Agreement is paid in full.  

    11.3     ERRORS.  If an error is discovered in any invoice
rendered hereunder (including reconciliations for actual deliveries of
any payments made by Buyer based on Seller's Estimate), such error
shall be adjusted within thirty (30) Days after notice of the
discovery of the error.  If a dispute arises as to the amount payable
pursuant to any invoice rendered hereunder, Buyer shall nevertheless
pay when due the amount
                                 -24-
<PAGE>

not in dispute under such invoice.  Such payment shall not be deemed
to be a waiver of the right by Buyer to recoup any overpayment, nor
shall acceptance of any payment be deemed to be a waiver by Seller of
any underpayment.

    11.4     OVERDUE PAYMENTS.  If Buyer fails to pay the entire
amount due to Seller when same is due, interest on any unpaid portion
shall accrue at a rate equal to the lesser of (i) three percent (3%)
above the rate of interest then most recently announced by Texas
Commerce Bank, National Association as its "prime rate" and (ii) the
maximum non-usurious rate of interest allowed by applicable law.

    11.5     AUDITING.   Each Party shall keep and maintain true and
correct books, records, files, and accounts of all information
reasonably related to the transactions contemplated by this Agreement
(the "Records"), including all measurement records, all information
used to determine prices and calculate invoices, and all invoices,
statements, and payment records.  All such Records shall be maintained
for at least forty-eight (48) Months after the Month to which they
pertain.  Either Party may, at its own expense, audit, and copy the
other Party's Records at any time during normal business hours upon at
least fifteen (15) Days' written notice.  No adjustment to any payment
made by Buyer to Seller for Seller's Gas sold hereunder shall be made
after the lapse of eighteen (18) Months from the date of any such
payment, except for any adjustments to such payments due to volume
adjustments of Seller's Gas delivered at the Delivery Points.

obligation to make payments due under this Agreement, if either Party
fails to observe or perform any of the covenants or obligations herein
imposed upon it and such failure shall have been occasioned by, in

the above requirement of the use of

or order which materially and adversely affects the rights or ability
to perform of either Party, then the affected Party may terminate this
Agreement by giving sixty (60) Days' written notice to the other

enforceable against Seller in accordance with their respective terms,
except that such enforceability may be limited by applicable

Permitted Encumbrance in accordance with PARAGRAPH (g) of the
definition thereof.

       5.6. LEGAL PROCEEDINGS. Except as otherwise set forth in
SCHEDULE 5.6, there are no Proceedings pending or, to Seller's
knowledge, overtly threatened against or involving Seller which might
result in the impairment or loss of title to any of the Oil and Gas

Oil and Gas Properties or that, if adversely determined, would delay
or prevent the consummation of the transactions contemplated hereby.

       5.7. COMPLIANCE WITH LAWS. Except as set forth in SCHEDULE 5.7,
Seller is not in violation of or in default under any Applicable Law
relating to the ownership or operation of the Oil and Gas Properties,

the commitment or investment of funds (other than routine expenses
incurred in the normal operation of existing wells on such Oil and Gas

Gas Property listed on SCHEDULE B, Seller has the right to explore

Properties, the representations and warranties in this SECTION 5.10

advised in writing by any other party to an Applicable Contract of
such party's intention or desire to terminate or modify in any
material respect such Applicable Contract (exclusive, however, of any
such termination or modification permitted in SECTION 7.1).

virtue of a prepayment arrangement, "take or pay" arrangement,

shown on SCHEDULE 5.12, Seller is not currently paying more than the
percentage of operating and other costs for each well listed on

such well and Seller is current for all costs and expenses pertaining
thereto for which it has been billed.

       5.13. PAYMENT OF EXPENSES. All expenses, (including, without
limitation, all bills for labor, materials and supplies used or
furnished for use in connection with the Oil and Gas Properties, and

the Properties that are not terminable on notice of sixty (60) days or
less;
       (g) (i) not sell, farmout, transfer, release, abandon (in each

       (j) promptly notify Buyer of any destruction of or damage to
any of the Oil and Gas Properties which Seller reasonably estimates to

<PAGE>
       (q) not decline to participate in or not refuse to consent to
an activity or project with respect to any of the Oil and Gas
Properties, whether by action or inaction, such that the Seller's net
revenue interest in such properties is diminished or reduced, except
where such election or refusal is as a result of an election of Buyer
not to approve an AFE which requires its consent pursuant to CLAUSE
(m) above or not to grant its consent under PARAGRAPH (n) above (and
the failure of Buyer to notify Seller of its consent within five days
(or such shorter time as specified by Seller, if the applicable
agreements or other exigent circumstances outside of Seller's control
so require) following prompt written notice of such AFE from Seller
(in the case of PARAGRAPH (m)) or following a prompt written request
therefor from Seller (in the case of PARAGRAPH (n)) shall be deemed to
constitute its disapproval);

       (r) except as permitted by SECTION 15.3 and as provided with
respect to the "Master Gas Purchase Agreement" described below, not

the costs and revenues of the Properties after the Effective Date,

affiliate of Seller relating to the Properties;

       (s) comply with all Applicable Laws pertaining to the
Properties;

       (t) cause all delay rentals, shut-in royalties, minimum

to be timely and properly paid (subject, however, to the limitations
described below in this SECTION 7.1); and

       (u) not acquire any additional interests in the Oil and Gas
Properties or lands adjoining the Oil and Gas Properties.

Notwithstanding the other provisions of this SECTION 7.1: (i) Seller
may take any actions it determines to be reasonably necessary under
emergency circumstances and provided Buyer is notified as soon
thereafter as possible; and (ii) Seller shall have no liability to
Buyer for the incorrect payments under PARAGRAPH (t) above or for any
failure to make any such payments, except in those instances in which
Seller is contractually obligated to make such payments and such
contractual obligations have not been assumed by another party. Any
consent requested of Buyer with respect to the matters covered by this
SECTION 7.1 shall not be unreasonably withheld or action with respect
thereto unduly delayed. Buyer agrees that Seller is authorized to
execute and deliver that certain Master Gas Purchase Agreement by and
among SFER, SFEOP and Adobe Gas Pipeline Company, in the form of the
agreement attached as an exhibit to that certain Agreement of Merger
dated July 28, 1993, by and among SFER, Adobe Gas Pipeline

                                  21
<PAGE>
Company and Hadson Corporation, and (subject to the consummation of
the transactions contemplated hereby) Buyer agrees to expressly assume
SFER's obligations thereunder to the extent applicable to the Oil and
Gas Properties conveyed hereunder.

       In connection with the provisions described in PARAGRAPHS (m),
(n) and (a) above, Seller and Buyer further agree as follows. If an
activity or other project is proposed with respect to an Oil and Gas
Property for which Seller is required to obtain Buyer's consent
pursuant to either PARAGRAPH (m) or PARAGRAPH (n) above, and (x) Buyer
declines to give its consent and (y) Seller, at the time of requesting
Buyer's consent, notifies Buyer that Seller desires to participate in
the proposed activity or other project (and to pay the costs
attributable to Seller's interest with respect thereto), then such Oil
and Gas Property will be excluded from the transactions contemplated
hereby (and will be deemed to be an Excluded Asset) and the Cash
Portion of the Purchase Price will be reduced by the amount allocated
to such Oil and Gas Property in SCHEDULE A or B. If an activity or
other project is proposed with respect to an Oil and Gas Property for
which Seller is required to obtain Buyer's prior consent pursuant to
either PARAGRAPH (m) or PARAGRAPH (n) above, and (x) Seller, at the
time of requesting Buyer's consent, informs Buyer in writing that
Seller would not recommend participation in such operation or
activity, (y) Seller is nonetheless required to participate in the
proposed activity or project pursuant to the provisions of PARAGRAPH
(q) above, and (z) the transactions contemplated by this Agreement are
not consummated and this Agreement is terminated pursuant to ARTICLE
XI, then, promptly after the point in time when this Agreement is so
terminated, Buyer shall purchase from Seller, and Seller shall convey
and assign to Buyer (without any warranties, of title or otherwise),
such Oil and Gas Property for an amount equal to the amount allocated
to such Oil and Gas Property in SCHEDULE A or B. In connection with
PARAGRAPH (u) above, Seller and Buyer further agree as follows. If
Seller is offered an additional interest in an Oil and Gas Property or
lands adjoining any Oil and Gas Property, Seller shall give prompt
notice to that effect to Buyer, which notice shall describe in
reasonable detail the interest involved, shall set forth the amount of
the proposed purchase price and any other obligations and commitments,
shall set forth whether Seller desires to acquire such interest for
its own account and shall set forth the time by which Buyer must
notify Seller as to whether or not Buyer consents to such acquisition.
If Buyer declines to grant its consent to the acquisition (or fails to
give a timely response) and Seller had indicated that it desired to
purchase the interest for its own account, then Seller may so purchase
such interest for its own account free and clear of any obligations to
Buyer hereunder. If Buyer grants its consent to the acquisition and
the transactions contemplated hereby are consummated, then Seller
shall convey such interest to Buyer at Closing and Buyer shall
reimburse Seller at the Closing for the amount of the purchase price
paid by Seller therefor and assume Seller's obligations and
commitments therewith. If Buyer grants its consent to the acquisition,
Seller had indicated it did not desire to purchase the interest for
its own account and the transactions contemplated hereby are not
consummated and this Agreement is terminated pursuant to ARTICLE XI,
then promptly after the 
                                  22
<PAGE>
point in time when this Agreement is so terminated, Seller shall
convey such interest to Buyer (without any warranties of title or
otherwise) and Buyer shall reimburse Seller for the amount of the
purchase price therefor and assume Seller's obligations and
commitments therewith. Notwithstanding the foregoing or anything else
herein to the contrary (including specifically PARAGRAPH (u) above,
Santa Fe shall be permitted to make an acquisition of additional
interests in Oil and Gas Properties and/or the lands adjoining the Oil
and Gas Properties and shall have no obligations or duties to Buyer
hereunder with respect thereto, provided that such additional
interests comprise 20% or less of the total value of the oil and gas
properties and other interests to be acquired by Seller in connection
with such acquisition.

       7.2. CONDUCT OF BUYER'S BUSINESS PRIOR TO CLOSING. During the
period from the date hereof to the Closing, Buyer (a) shall conduct
its business and operations in accordance in all material respects
with the conduct of its business and operations as described in the
Initial Registration Statement and in compliance with all Applicable
Laws; (b) shall use its reasonable best efforts to preserve, maintain,
and protect its properties; and (c) shall use its reasonable best
efforts to preserve intact its business organization, to keep
available the services of its officers and employees, and to maintain
existing relationships with licensors, licensees, suppliers,
contractors, distributors, customers, and others having business
relationships with it. Without limiting the generality of the
foregoing, and except as otherwise expressly contemplated in this
Agreement or as described in the Initial Registration Statement, prior
to the Closing, Buyer shall not, without the prior written consent of
Seller:
        (i) amend its charter or bylaws;

       (ii) (A) issue, sell, or deliver (whether through the issuance
or granting of options, warrants, commitments, subscriptions, rights
to purchase, or otherwise) any shares of its capital stock of any
class or any other securities or equity equivalents; or (B) amend in
any respect any of the terms of any such securities outstanding as of
the date hereof; or

       (iii) (A) split, combine, or reclassify any shares of its
capital stock; (B) declare, set aside, or pay any dividend or other
distribution (whether in cash, stock, or property or any combination
thereof) in respect of its capital stock; (C) repurchase, redeem, or
otherwise acquire any of its securities; or (D) adopt a plan of
complete or partial liquidation or resolutions providing for or
authorizing a liquidation, dissolution, merger, consolidation,
restructuring, recapitalization, or other reorganization of Buyer.

       7.3. ACCESS TO INFORMATION. Between the date hereof and the
Closing, (a) Seller shall give Buyer and its authorized
representatives reasonable access to the offices, properties, records,
marketing agreements, files, seismic data, engineering reports and
evaluations, books of account, computer records and all other
information of Seller pertaining to the Properties, including all 
                                  23
<PAGE>
land material, for the investigation of the Properties, the status
thereof and the title thereto, through Buyer's employees, attorneys,
independent public accountants or outside consultants and (b) Buyer
shall give Seller and its authorized representatives reasonable access
to the offices, properties, records, marketing arrangements, files,
etc. of Buyer; provided, however, that such investigations shall be
conducted during normal business hours and in a manner that does not
unreasonably interfere with Seller's or Buyer's, as the case may be,
normal operations and employee relationships. Each party shall cause
its personnel to assist the other party in making such investigation
and transferring the Properties, and the operations thereof, and shall
cause its counsel, accountants, employees and other representatives to
be reasonably available to the other party for such purposes. During
such investigation, each party shall have the right to make copies of
such records, files and other materials of the other party as such
party may deem advisable.

       7.4.  CONFIDENTIALITY. The confidentiality agreements (a) dated
October 8, 1993, between Seller and Buyer and (b) dated October 1,
1993, between Seller and Parent, as each are modified by that certain
letter dated October 8, 1993, among Seller, Buyer and Parent, shall
remain in full force and effect.

       7.5. HSR ACT NOTIFICATION. To the extent required by the HSR
Act, each of the parties hereto shall (a) file or cause to be filed,
as promptly as practicable but in no event later than 15 days after
the execution and delivery of this Agreement, with the Federal Trade
Commission and the United States Department of Justice, all reports
and other documents required to be filed by such party under the HSR
Act concerning the transactions contemplated hereby and (b) use its
reasonable best efforts to promptly comply with or cause to be
complied with any requests by the Federal Trade Commission or the
United States Department of Justice for additional information
concerning such transactions, in each case so that the waiting period
applicable to this Agreement and the transactions contemplated hereby
under the HSR Act shall expire as soon as practicable after the
execution and delivery of this Agreement. Each party hereto agrees to
request, and to cooperate with the other party or parties in
requesting, early termination of any applicable waiting period under
the HSR Act.
       7.6. PUBLIC OFFERING. Buyer agrees that within ten days after
the execution and delivery of this Agreement, Buyer shall file a
registration statement (such registration statement, plus all
incorporated documents, exhibits and financial statements, and any
amendments thereto, being called the "REGISTRATION STATEMENT") with
the SEC in contemplation of a public offering of not less than
$75,000,000 of Bridge Common Stock. Buyer will use its best efforts to
cause the Registration Statement to become effective and to sell the
registered shares in the above contemplated public offering not later
than March 31, 1994, to realize aggregate proceeds therefrom in an
amount not less than $75,000,000 (prior to underwriting discounts and
payment of expenses attributable to the Offering) and to realize
proceeds, after deducting therefrom all amounts paid or, at the
Closing Date, anticipated to be paid to Parent out of such proceeds, in 
                                  24
<PAGE>
an amount not less than $25,000,000 (prior to underwriting discounts
and payment of expenses attributable to the Offering); provided, that
Buyer shall not be required to consummate such offering if it
determines in its sole and absolute discretion that the price per
share of Bridge Common Stock which would otherwise be received in
connection therewith is not an acceptable price per share of Bridge
Common Stock or that such offering is otherwise not in the best
interests of Buyer or Parent. If Buyer makes a determination not to
consummate the above contemplated public offering, it shall as
promptly as possible give written notice to that effect to Seller
(such notice being called the "OFFERING TERMINATION NOTICE") which
notice shall be given to Seller no later than March 31,1994; provided,
that if such offering is not consummated on or before March 31, 1994,
and if Seller has not otherwise received an Offering Termination
Notice by March 31, 1994, then Buyer shall be deemed to have given
Seller an Offering Termination Notice on March 31,1994. Seller will
cooperate with Buyer in the preparation of the Registration Statement
and will furnish or make available all information, including
financial information, with respect to the Properties which Buyer
reasonably requests for inclusion therein in order to comply with
Applicable Laws. Buyer will furnish to Seller a copy of the Initial
Registration Statement and each amendment or supplement thereto. Buyer
shall keep Seller informed from time to time as to the status of the
Registration Statement and in any event shall inform Seller (a) upon
the effectiveness of the Registration Statement under the Securities
Act, (b) upon pricing of the securities under the Registration
Statement or (c) upon receipt by Buyer of notice from the SEC of
notice of the issuance of a stop order with respect to the
Registration Statement. Seller and Buyer agree that a preliminary
closing of the transactions contemplated hereby shall be held on or
about one business day prior to the date on which the public offering
contemplated by the Registration Statement is consummated. At any such
preliminary closing, the closing documents under this Agreement shall
be presented and examined by Buyer and Seller and all documents deemed
satisfactory shall be held in escrow until the Closing.

       7.7. REGISTRATION RIGHTS AGREEMENT. Seller and Buyer shall
enter into a "REGISTRATION RIGHTS AGREEMENT" (as herein called) at

the Closing Seller acquires Bridge Common Stock as provided in ARTICLE III).

       7.8. INVESTMENT AGREEMENT. Seller, Buyer and Parent shall enter
into an "Investment Agreement" (as herein called) at (and subject to
the occurrence of) the Closing in substantially the form of such

       7.9. EXPLORATION AGREEMENT. SFEOP and Buyer shall enter into an

                                  25
<PAGE>
       7.10. NOTICE OF LITIGATION. Until the Closing, (a) Buyer, upon
learning of the same, shall promptly notify Seller of any Proceeding
which is commenced or threatened against Buyer and which affects this
Agreement or the transactions contemplated hereby and (b) Seller, upon
learning of the same, shall promptly notify Buyer of any Proceeding
which is commenced or threatened against Seller and which affects this
Agreement or the transactions contemplated hereby.

       7.11. NOTIFICATION OF CERTAIN MATTERS. Seller shall give prompt
notice to Buyer of (a) the occurrence or nonoccurrence of any event
the occurrence or nonoccurrence of which would be likely to cause any
representation or warranty contained in ARTICLE V to be untrue or
inaccurate at or prior to the Closing and (b) any failure of Seller to
comply with or satisfy any covenant, condition, or agreement to be
complied with or satisfy any covenant, condition, or agreement to be
complied with or satisfied by Seller hereunder. Buyer shall give
prompt notice to Seller of (i) the occurrence or nonoccurrence of any
event the occurrence or nonoccurrence of which would be likely to
cause any representation or warranty contained in ARTICLE VI to be
untrue or inaccurate at or prior to the Closing and (ii) any failure
of Buyer to comply with or satisfy any covenant, condition, or
agreement to be complied with or satisfied by Buyer hereunder. The
delivery of any notice pursuant to this Section shall not be deemed to
(A) modify the representations or warranties hereunder of the party
delivering such notice, (B) modify the conditions set forth in
ARTICLES IX and X, or (C) limit or otherwise affect the remedies
available hereunder to the party receiving such notice.

       7.12. PREFERENTIAL RIGHT TO PURCHASE. Seller shall request,
from the appropriate parties (and in accordance with the documents
creating such rights or requirements), waivers of the preferential
rights to purchase, or requirements that consent to assignments be
obtained, which exist with respect to the transfer by Seller to Buyer
of any of the Oil and Gas Properties. Seller shall have no obligation
hereunder other than to so request such waivers (I.E., Seller shall
have no obligation to assure that such waivers are obtained), and if
any such waiver is not obtained, Buyer may treat such failure to
obtain such waiver as a matter which constitutes a Title Defect;
provided, however, that if the third party holding a preferential
right to purchase exercises such right and completes the purchase of
the subject Oil and Gas Property prior to the Closing, such Oil and
Gas Property shall be excluded from the transactions contemplated
hereby (and shall be deemed to be an Excluded Asset) and the Cash
Portion of the Purchase Price shall be reduced by the amount allocated
to such Oil and Gas Property on SCHEDULE A or B; provided, further,
that if a third party holding a right to consent to an assignment of
an Oil and Gas Property listed in SCHEDULE A or B, which consent was
not obtained prior to Closing and was not treated as a Title Defect,
notifies Buyer or Seller after the Closing but prior to the second
anniversary date of the Closing Date that such third party objects to
the transfer of such Oil and Gas Property to Buyer, Buyer and Seller
shall take either of the following actions, as mutually determined:
(a) title to such Oil and Gas Property shall be reassigned to Seller
as of the Effective Date, Seller shall pay to Buyer an amount equal to
the amount allocated to such Oil and Gas Property on 

                                  26
<PAGE>
SCHEDULE A or B, and Buyer shall account to Seller for all revenues
and costs attributable to such Oil and Gas Property from and after the
Effective Date until the date of reassignment and tender to Seller the
amount of net income attributable to such Oil and Gas Property from
the Effective Date to the date of reassignment; or (b) title to such
Oil and Gas Property shall be reassigned to Seller, and Buyer and
Seller shall enter into a written arrangement on terms mutually
acceptable to the both of them the purpose of which will be to provide
Buyer the same economic benefits from such Oil and Gas Property as if
title to such Oil and Gas Property were still held by it.

       7.13. PUBLIC ANNOUNCEMENTS. The parties hereto agree that prior
to making any public announcement or statement with respect to the
transactions contemplated by this Agreement, the party desiring to
make such public announcement or statement shall consult with the
other party hereto and exercise its reasonable best efforts to (a)
agree upon the text of a joint public announcement or statement to be
made by both or such parties or (b) obtain approval of the other party
hereto to the text of a public announcement or statement to be made
solely by Seller or Buyer, as the case may be. Nothing contained in
this Section shall be construed to require either party to obtain
approval of the other party hereto to disclose information with
respect to the transactions contemplated by this Agreement to any
state or federal governmental authority or agency to the extent
required by Applicable Laws or necessary to comply with the disclosure
requirements of any stock exchange having jurisdiction over the
disclosing party.

       7.14. FILING AND RECORDING OF ASSIGNMENTS, ETC. Buyer shall be
solely responsible for all filings and recording of assignments and
other documents related to the Properties and for all fees connected
therewith, and Buyer shall furnish Seller with pertinent recording
data. Seller shall not be responsible for any loss to Buyer because of
Buyer's failure to file or record documents correctly or promptly.
Bearer shall promptly file all appropriate forms, declarations or
bonds with federal and state agencies relative to its assumption of
operations and Seller shall cooperate with Buyer in connection with
such filings.

       7.15. ACCESS TO RECORDS AFTER CLOSING. Buyer agrees to maintain
the files and records of Seller that are acquired pursuant to this
Agreement until the fourth anniversary of the Closing Date (or for
such longer period of time as Seller shall advise Buyer is necessary
in order to have records available with respect to open years for tax
audit purposes), or, if any of such records pertain to any claim or
dispute pending on the fourth anniversary of the Closing Date, Buyer
shall maintain any of such records designated by Seller until such
claim or dispute is finally resolved and the time for all appeals has
been exhausted. Buyer shall provide Seller and its representatives
reasonable access to and the right to copy such files and records for
the purposes of (a) preparing and delivering any accounting provided
for under this Agreement and adjusting, prorating and settling the
charges and credits provided for in this Agreement, (b) complying with
any law, rule or regulation affecting Seller's interest in the
Properties prior to the Closing Date, (c) preparing any audit of the

<PAGE>
prior to the Closing Date or responding to any audit prepared by such
third parties, (d) preparing tax returns, (e) responding to or
disputing any tax audit or (f) asserting, defending or otherwise
dealing with any claim or dispute under this Agreement. In no event
shall Buyer destroy any such files and records without giving Seller
sixty (60) days advance written notice thereof and the opportunity, at
Seller's expense, to obtain such files and records prior to their
destruction.
       7.16.  TRANSFER OF GEOSCIENCE DATA. The parties hereto
acknowledge and agree that Seller shall be required to transfer the
Geoscience Data to the extent that if, in Seller's reasonable opinion
at the Closing, it can do so without incurring liability by violating
the terms of a third-party agreement; provided, however, that in those
instances in which Seller can avoid such liability by obtaining the
consent of a third party, it will use its reasonable efforts (without
any obligation to pay additional fees or incur any significant or
undue cost or expense) to do so; provided, further, that to the extent
that a transfer of such data is prohibited, but the review by Buyer of
such data is not, then Seller shall (without obligation to pay
additional fees or incur any substantial or undue cost or expense)
maintain such data which shall be maintained in Houston, Texas, as
long as Seller or any affiliate of Seller maintains an office in
Houston, Texas, and thereafter at Seller's principal place of business
for five years following the Closing and Buyer shall have the
continuing right to review such data.

       7.17.  SANTA FE SEPARATE DISCLOSURE SCHEDULE. As promptly as
reasonably practicable and in any event no later than December 20,
1993, Seller shall deliver to Buyer a schedule or schedules setting
forth: (a) a list of all Applicable Contracts in effect on the
Effective Date and all Applicable Contracts in effect on the date of
this Agreement; (b) a list of all preferential rights of purchase that
exist with respect to the transfer by Seller to Buyer of the Oil and
Gas Properties; and (c) a list of all consents of third parties that
exist with respect to the transfer by Seller to Buyer of the Oil and
Gas Properties. Such schedule or schedules shall be herein called the
"SANTA FE SEPARATE DISCLOSURE SCHEDULE."

       7.18. SALES AND OTHER TAXES. Buyer shall bear and timely pay
(a) upon receipt of the invoice of Seller thereof, all state or local
government sales taxes incident to the transfer of the Properties to
Buyer, (b) all documentary, transfer and other similar state and local
government taxes incident to the transfer of the Properties to Buyer
and (c) all costs or fees required to obtain consents to assign any
Federal or state leases included in the Properties.

       7.19.  FEES AND EXPENSES. Except as otherwise expressly
provided in this Agreement, all fees and expenses, including fees and
expenses of counsel, financial advisors, and accountants, incurred in
connection with this Agreement and the transactions contemplated
hereby shall be paid by the party incurring such fee or expense,
whether or not the Closing shall have occurred.

       7.20.  BROKERS. Seller agrees to indemnify and hold harmless
Buyer (without regard to the limitations set forth in ARTICLE XII)
from and against any and all losses, claims, damages,

                                  28
<PAGE>
costs and expenses, including, without limitation, reasonable
attorneys' fees and expenses, Buyer may sustain or incur as a result
of any claim for a commission or fee by a broker or finder acting on
behalf of Seller. Buyer agrees to indemnify and hold harmless (without
regard to the limitations set forth in ARTICLE XII) Seller from and
against any and all losses, claims, damages, costs and expenses,
including, without limitation, reasonable attorneys' fees and
expenses, Seller may sustain or incur as a result of any claim for a
commission or fee by a broker or finder acting on behalf of Buyer.

       7.21. OVER-ALLOTMENT OPTION AFTER CLOSING. If the Underwriters
exercise the over-allotment option granted to them by Buyer under the
Underwriting Agreement and the number of shares of Bridge Common Stock
has not been reduced to zero pursuant to ARTICLE III, Buyer shall,
within 15 days after the exercise of such option, deliver to Seller a
certificate or certificates representing shares (the "ADDITIONAL
SHARES") of Bridge Common Stock in an amount such that the sum of (a)
the shares of Bridge Common Stock tendered to Seller pursuant to
ARTICLE III plus (b) the Additional Shares, shall equal 10% of all
issued and outstanding shares of Bridge Common Stock excluding any
shares of Bridge Common Stock issued under the Bridge Oil & Gas Inc.
1993 Stock Option Plan in the amount and as described in the Initial
Registration Statement (but taking into account the exercise by the
Underwriters of such over-allotment option). In consideration therefor
and simultaneously therewith, Seller shall, in the event and to the
extent that the Initial Stock Value is less than $36,000,000, deliver
to Buyer cash in an amount equal to the number of Additional Shares
multiplied by the Offering Price.

       7.22. AGREEMENT TO CONVEY. Except for any interest in any well,
which interest is burdened by the net profits interest conveyed to the
Royalty Trust, or except for any well located in any of the counties
listed in SCHEDULE 7.22, Seller agrees that to the extent not
otherwise conveyed to Buyer at the Closing, Seller will convey and
assign to Buyer any interest which Seller owns as of as of the date
hereof (exclusive of any interest disposed of by Seller in accordance
with SECTION 7.1) in any well that, under Applicable Law, is located
within one legal location of, and in the same reservoir as, any well
or unit listed on SCHEDULE A-1 or any proposed unit for an undrilled
well listed on SCHEDULE A-1.

       7.23. BRITT RANCH IMBALANCE. Upon the consummation of the
transactions contemplated hereby, Buyer shall succeed to the position
of Seller with respect to the Imbalances. As a result of such
succession, Buyer shall (a) be entitled to receive any and all
benefits, including payments of proceeds of production in excess of
amounts which it would otherwise be entitled to produce and receive by
virtue of ownership of the Oil and Gas Properties, which Seller would
have been entitled to receive by virtue of such positions and (b)
shall be obligated to suffer any detriments (whether the same be in
the form of obligations to deliver production which would have
otherwise been attributable to its ownership of the Oil and Gas
Properties without receiving full payment therefor, or be in the form
of the obligation to make payment in cash) which Seller would have
been obligated to suffer by virtue of such positions. Notwithstanding
the foregoing or anything
                                  29
<PAGE>
else herein to the contrary, Buyer and Seller agree that Buyer shall
pay to Seller, and Seller shall be entitled to receive from Buyer, 75%
of all amounts that Buyer or its assigns hereafter receives that is
attributable to the "under-produced" position of Seller with respect
to the Oil and Gas Property identified on SCHEDULE 5.21 as (and herein
called) "Britt Ranch." Buyer agrees that from and after the Closing it
will use and will cause its assigns to use its reasonable best efforts
to collect all amounts due and owing it attributable to the above-described
underproduction and to otherwise enforce all rights and
privileges under the applicable gas balancing provisions governing
Britt Ranch. Payment of amounts due and owing Seller under this
SECTION 7.23 shall be made by Buyer promptly after receipt of the
underlying funds in which Seller is accorded the above described
rights. All payments to Seller under this Section shall be accompanied
by a schedule prepared by Buyer that sets forth a reasonably detailed
description of the facts and circumstances giving rise to such payment
and the manner in which the amount paid to Seller was calculated.
Buyer agrees to provide Seller and its representatives with reasonable
access during Buyer's normal business hours to Buyer's books and
records maintained in connection with the Imbalance on Britt Ranch and
to such other information in Buyer's possession as Seller may
reasonably request with respect thereto.
       7.24. WYOMING AD VALOREM TAX. Seller and Buyer specifically
agree that all ad valorem taxes in respect of the Properties imposed
by the State of Wyoming that are due and payable in calendar year 1994
and thereafter, shall be the sole responsibility of Buyer (and Seller
shall have no liability with respect thereto) and shall not be
included in the adjustments to the Purchase Price under ARTICLE XIV. 

       7.25. PURCHASE OF TAYLORCO NPI. If, prior to the transfer
hereunder by Seller to Buyer of an Oil and Gas Property that is
burdened with a net profits interest in favor of Taylorco pursuant to
the Taylorco Purchase Agreement, Taylorco elects to sell such net
profits interest to Seller pursuant to Section 4.8(b) of the Taylorco
Purchase Agreement at a price satisfactory to Buyer, Buyer shall
reimburse Seller at Closing for the amount paid by Seller to Taylorco.

       7.26. FURTHER ASSURANCES. After the Closing each of the parties
will execute, acknowledge and deliver to the other such further
instruments, and take such other action, as may be reasonably
requested in order to more effectively assure to said party all of the
respective properties, rights, titles, interests, estates, and
privileges intended to be assigned, delivered or inuring to the
benefit of such party in consummation of the transactions contemplated
hereby.

    VIII. TITLE DEFECTS AND RELATED PURCHASE PRICE ADJUSTMENTS

       8.1. NOTICE OF TITLE DEFECTS. Buyer shall, by no later than
December 27, 1993, give Seller written notice of any claimed Title
Defect, which notice shall set forth (a) a brief description of the
matter constituting the claimed Title Defect; (b) supporting documents
reasonably necessary for Seller to verify the claimed Title Defect;
(c) the identity of the Oil and Gas Property that is affected by the
claimed Title Defect; and (d) any claimed Purchase Price reduction
attributable to the claimed Title Defect. Buyer shall be deemed to
have waived all Title Defects of which Seller has not been given such
notice by such date. Seller shall have the right, but not the
obligation, to attempt to cure any claimed Title Defect within 20 days
after Seller receives Buyer's notice of Title Defect. Buyer shall be
obligated to notify Seller in writing of Buyer's acceptance or
rejection of the result obtained by Seller in its efforts to cure any
claimed Title Defects not more than five days after Seller notifies
Buyer in writing of such result. If Seller disagrees that a Title
Defect exists or is uncured or disagrees with the amount of the
related Purchase Price reduction claimed by Buyer in any notice given
in accordance with this SUBSECTION (A), then Buyer and Seller shall
promptly meet and negotiate in good faith in an attempt to resolve the
disagreement. If Buyer and Seller are unable to resolve their
disagreement and if the item is not waived by Buyer as a Title Defect
prior to Closing, then, for purposes hereof, the item which is the
subject of disagreement shall be deemed to be a Title Defect.

       8.2. PURCHASE PRICE REDUCTIONS FOR TITLE DEFECTS. With respect
to any uncured Title Defect determined to exist pursuant to SECTION
8.1 and not waived by Buyer prior to the Closing, the amount allocated
to any Title Defect shall be determined as follows:

          (a) If the Title Defect results in a complete failure of
     Seller's title to any Oil and Gas Property listed on SCHEDULE A-1,
     the amount allocated to that Title Defect shall equal the
     dollar amount allocated to that Oil and Gas Property as set forth
     in SCHEDULE A-1 attached hereto.

          (b) If the Title Defect does not result in a complete
     failure of Seller's title to any Oil and Gas Property listed on
     SCHEDULE A-1 but results in a decrease in the net revenue
     interest for that Oil and Gas Property from that shown in     
     SCHEDULE A-1, then the amount allocated to that Title Defect
     shall be equal to the product of the dollar amount allocated to
     that Oil and Gas Property as set forth in SCHEDULE A-1 multiplied
     by a fraction the numerator of which is the difference between
     (A) the net revenue interest for that Oil and Gas Property set
     forth in SCHEDULE A-1 and (B) the actual net revenue interest of
     Seller in that Oil and Gas Property, and the denominator of which
     is the net revenue interest for that Oil and Gas Property set
     forth in SCHEDULE A-1.

          (c) If the Title Defect does not result in a complete
     failure of Seller's title to any Oil and Gas Property listed on
     SCHEDULE A-1 that is not a "composite property" (as

                                  31
<PAGE>

     reflected in such Schedule) but results in an increase in the
     working interest for that Oil and Gas Property from that shown in
     SCHEDULE A-1, then the amount allocated to such Title Defect
     shall be an amount equal to the present value as of the Effective
     Date (discounted at 10% compounded annually) of the future costs
     and expenses related to the maintenance, development and
     operation of such Oil and Gas Property which are forecasted in
     the Reserve Report, multiplied by the amount (expressed in terms
     of a percentage) that the increase in working interest in such
     Oil and Gas Property exceeds any corresponding increase in net
     revenue interest in such Oil and Gas Property from that shown in
     SCHEDULE A-1.

          (d) If the Title Defect results in a complete failure of
     Seller's title to any Oil and Gas Property listed on SCHEDULE B,
     then the amount allocated to such Title Defect shall be an amount
     equal to the product of the dollar amount per acre set forth in
     SCHEDULE B for that Oil and Gas Property multiplied by the number
     of net acres set forth in SCHEDULE B for that Oil and Gas
     Property.

          (e) If the Title Defect does not result in a complete
     failure of Seller's title to any Oil and Gas Property listed on
     SCHEDULE B but results in a reduction in the number of net acres
     for that Oil and Gas Property from that shown in SCHEDULE B, then
     the amount allocated to such Title Defect shall be an amount
     equal to the product of the dollar amount per acre set forth in
     SCHEDULE B for that Oil and Gas Property multiplied by the
     difference between (A) the number of net acres set forth in
     SCHEDULE B for that Oil and Gas Property and (B) the actual
     number of net acres of Seller in that Oil and Gas Property.

The sum of the amounts allocated to the Title Defects described above
shall be herein called the "PURCHASE PRICE REDUCTIONS." If a Title
Defect that is not waived by Buyer prior to Closing results in a
complete failure of Seller's title to an Oil and Gas Property, such
Oil and Gas Property shall be excluded from the transactions
contemplated hereby. If a Title Defect that is not waived by Buyer
prior to Closing does not result in a complete failure of Seller's
title to an Oil and Gas Property, that portion of such Oil and Gas
Property that is affected by the Title Defect shall be excluded from
the transactions contemplated hereby to the extent practicable.

       8.3. PURCHASE PRICE INCREASES. Seller shall, by no later than
December 27, 1993, give Buyer written notice of any matters of the
type described in SUBSECTIONS (A) through (C) below, which Seller
believes should result in an increase in the Purchase Price. Such
notice shall set forth: (a) a brief description of the matter giving
rise to the claimed increase in the Purchase Price; (b) supporting
documents reasonably necessary for Buyer to verify the claimed
increase in Purchase Price; (c) the identity of the Oil and Gas
Property that is affected by the claimed increase in Purchase Price;
and (d) the amount of the claimed increase in Purchase Price. If Buyer
disagrees that a claimed increase in Purchase Price is warranted or
disagrees with the

                                  32

<PAGE>

amount of the related increase in the Purchase Price claimed by Seller
in any notice given in accordance with this SECTION 8.3, then Buyer
and Seller shall promptly meet and negotiate in good faith in an
attempt to resolve the disagreement. If Buyer and Seller are unable to
resolve their disagreement and if Seller does not waive its claim for
an increase in the Purchase Price prior to the Closing, then, for
purposes hereof, the matter which is the subject of disagreement shall
result in an increase in the Purchase Price. The Purchase Price shall,
in any event, be increased in the event the circumstances described in
SUBSECTION (D) below are operative. An increase in the Purchase Price,
to the extent not waived by Seller prior to the Closing, shall be
determined as follows:

          (a) If it is determined that the ownership by Seller of an
     Oil and Gas Property listed in SCHEDULE A-1 entitles Seller to a
     net revenue interest in that Oil and Gas Property in excess of
     that shown in SCHEDULE A-1, then the amount of the increase to
     the Purchase Price shall equal the product of the dollar amount
     allocated to that Oil and Gas Property as set forth on SCHEDULE
     A-1 multiplied by a fraction, the numerator of which is the
     difference between (a) the actual net revenue interest of Seller
     for that Oil and Gas Property and (B) the net revenue interest
     for that Oil and Gas Property set forth in SCHEDULE A-1 and the
     denominator of which is the net revenue interest for that Oil and
     Gas Property set forth in SCHEDULE A-1.

          (b) If it is determined that with respect to an Oil and Gas
     Property listed in SCHEDULE A-1 (other than a "composite
     property" as reflected thereon) that Seller's working interest
     for that Oil and Gas Property is less than that shown on SCHEDULE
     A-1, then the amount of the increase in the Purchase Price shall
     be an amount equal to the present value as of the Effective Date
     (discounted at 10% compounded annually) of the future costs and
     expenses related to the maintenance, development and operation of
     such Oil and Gas Property which are forecasted in the Reserve
     Report, multiplied by the amount (expressed in terms of a
     percentage) that the decrease in working interest in such Oil and
     Gas Property exceeds any corresponding decrease in net revenue
     interest in such Oil and Gas Property from that shown in SCHEDULE
     A-1.

          (c) If it is determined that the ownership by Seller of an
     Oil and Gas Property listed in SCHEDULE B entitles Seller to net
     acres in that Oil and Gas Property in excess of that shown in
     SCHEDULE B, then the amount of the increase in the Purchase Price
     shall equal the product of the dollar amount set forth in
     SCHEDULE B for that Oil and Gas Property multiplied by the
     difference between (A) the actual number of net acres of Seller
     in that Oil and Gas Property and (B) the number of net acres set
     forth in SCHEDULE B for that Oil and Gas Property.

          (d) If (i) Seller owns a well that is not an Oil and Gas
     Property and that, under Applicable Law, is more than one legal
     location removed from and in the same reservoir
                                  33
<PAGE>

     as a well or unit that is listed on SCHEDULE A-1 or any proposed
     unit for an undrilled well listed on SCHEDULE A-1, and with
     respect to which Seller elects to offer to Buyer for inclusion
     with the Properties to be conveyed hereunder and (ii) Seller and
     Buyer mutually agree upon the purchase price for such well and to
     include it with the Properties to be conveyed, then the Purchase
     Price shall be increased by the amount of the mutually agreed
     upon purchase price.

The sum of the increases in the Purchase Price described above shall
be herein called the "PURCHASE PRICE INCREASES."

       8.4. ADJUSTMENT TO PURCHASE PRICE. If the Purchase Price
Reductions are greater than the Purchase Price Increases, then the
Cash Portion of the Purchase Price payable by Buyer at Closing shall
be reduced to the extent of the difference between such amounts. If
the Purchase Price Increases are greater than the Purchase Price
Reductions, then the Cash Portion of the Purchase Price shall be
increased to the extent of the difference between A and B, where A is
the difference between the Purchase Price Increases and the Purchase
Price Reductions, and where B is $400,000.

       8.5. RIGHT TO TERMINATE. If the amount of the reduction or
increase to the Cash Portion of the Purchase Price determined pursuant
to SECTION 8.4 equals or exceeds $1,000,000, then, subject to
SUBSECTIONS (b) and (c) below of SECTION 8.6, either Seller or Buyer
shall have the right to terminate this Agreement.

       8.6. CERTAIN AGREEMENTS REGARDING DISPUTES.

          (a) If (i) neither party has the right to terminate this
     Agreement pursuant to SECTION 8.5, (ii) the parties hereto were
     unable to resolve their disagreement over any Claimed Defects or
     any Claimed Increases pursuant to the terms hereof and (iii) the
     Closing occurs, then, (A) at the Closing, the Cash Portion of the
     Purchase Price shall be reduced by the amount of Agreed Defects
     and increased by the amount of Agreed Increases and (B) within
     five days after the Closing, either party hereto may submit its
     disagreement over any Claimed Defects or any Claimed Increases
     for resolution pursuant to the provisions of SUBSECTION (d)
     below.

          (b) If (i) either party has the right to terminate this
     Agreement pursuant to SECTION 8.5, and (ii) the parties hereto
     were unable to resolve their disagreement over Claimed Defects or
     Claimed Increases pursuant to the terms hereof, then, upon the
     election of Buyer, Seller shall forfeit its right to terminate
     this Agreement pursuant to SECTION 8.5, provided, that (A) at the
     Closing, the Cash Portion of the Purchase Price shall be reduced
     by the amount of Agreed Defects and increased by the amount of
     Agreed Increases (provided, that in no event can the Cash Portion
     of the Purchase Price be

                                  34
<PAGE>

     reduced by more than $1,000,000), (B) within five days after the
     Closing, either party hereto may submit its disagreement over
     such Claimed Defects or Claimed Increases for resolution pursuant
     to the provisions of SUBSECTION (D) below and (C) in no event can
     the amount of the reduction to the Purchase Price, giving effect
     to all Agreed Defects and Agreed Increases and after operation of
     SUBSECTION (d) below, exceed $1,000,000.
          (c) If (i) either party has the right to terminate this
     Agreement pursuant to SECTION 8.5 and (ii) the parties hereto
     were unable to resolve their disagreement over Claimed Defects or
     Claimed Increases pursuant to the terms hereof, then, upon the
     election of Seller, Buyer shall forfeit its right to terminate
     this Agreement pursuant to SECTION 8.5, provided that (A) at the
     Closing, the Cash Portion of the Purchase Price shall be reduced
     by the amount of Agreed Defects and increased by the amount of
     Agreed Increases (provided that in no event can the Cash Portion
     of the Purchase Price be increased by more than $1,000,000) and
     (B) within five days after the Closing, either party hereto shall
     submit its disagreement over such Claimed Defects or Claimed
     Increases for resolution pursuant to SUBSECTION (d) below and (C)
     in no event can the amount of the increase to the Purchase Price,
     giving effect to Agreed Defects and Agreed Increases and after
     operation of SUBSECTION (d) below, exceed $1,000,000.

          (d) Any disagreement between the parties hereto of the type
     referenced in SUBSECTION (A), SUBSECTION (B) or SUBSECTION (C)
     above, shall be finally settled by arbitration conducted in
     accordance with the Commercial Arbitration Rules of the American
     Arbitration Association, except as such rules may conflict with
     the provisions of this SUBSECTION (D) (in which event the
     provisions of this SUBSECTION (D) shall control). Each party
     shall choose one arbitrator and a third arbitrator shall be
     selected by mutual agreement of the party-appointed arbitrators
     within 30 days after the date of the last party-appointed
     arbitrator. If for any reason a vacancy occurs in the panel of
     arbitrators, a replacement arbitrator shall be appointed by the
     party who selected the predecessor arbitrator (or, if the
     predecessor arbitrator was appointed by the party-appointed
     arbitrators, the party-appointed arbitrators shall appoint the
     replacement arbitrator). Any decision of the arbitrators shall be
     final and binding upon the parties hereto. If, as a result of the
     decision of the arbitrators, the Cash Portion of the Purchase
     Price should be reduced, Seller shall pay to Buyer in cash by
     wire transfer of immediately available funds, within two business
     days after the decision of the arbitrators, an amount equal to
     such reduction with interest thereon from the Closing Date until
     payment at the lower of the prime rate of interest charged by
     Bank of Montreal (as adjusted from time to time to reflect
     changes in such rate) or the highest lawful rate permitted by
     applicable law. If, as a result of the decision of the
     arbitrators, the Cash Portion of the Portion Price should be
     increased, Buyer shall pay to Seller in cash by wire transfer of
     immediately available funds, within two business days after the
     decision of the arbitrators, an amount equal to such increase
     with interest thereon from the Closing Date until payment at the

                                  35
<PAGE>

     lower of the prime rate of interest charged by Bank of Montreal
     (as adjusted from time to time to reflect changes in such rate)
     or the highest lawful rate permitted by applicable law. The fees
     of the arbitrators and the costs of the arbitration shall be
     shared equally by the parties hereto.

       8.7. ALLOCATIONS. It is hereby agreed that the dollar amount
allocated to any Oil and Gas Property on either SCHEDULE A or SCHEDULE
B shall be used only for the purposes set forth in SECTION 7.1, in
this ARTICLE VIII and for purposes of determining value in the event
of the exercise of any preferential right of purchase relating to any
of the Oil and Gas Properties, and is not intended as a measure of
value for any other or general purpose.
               IX. CONDITIONS TO OBLIGATIONS OF SELLER

                    (i) the Closing shall not have occurred on or
               before April 11, 1994, unless such failure to close
               shall be due to a breach of this Agreement by the party
               seeking to terminate this Agreement pursuant to this
               CLAUSE (i); or

                    (ii) there shall be any statute, rule, or
               regulation that makes consummation of the transactions
               contemplated hereby illegal or otherwise prohibited or

               decree, or ruling or taken any other action permanently
               restraining, enjoining, or otherwise prohibiting the
               consummation of the transactions contemplated hereby,
               and such order, decree, ruling, or other action shall
               have become final and nonappealable; or

               (c) by either Seller or Buyer as the case may be, as

               (d) by Buyer, as provided in ARTICLE XIII.

In the event of the termination of this Agreement pursuant to this

in this Section and in SECTIONS 7.4, 7.13 and 7.19 and 7.20 shall
survive the termination hereof. Nothing contained in this Section
shall relieve any party from liability for any breach of this
Agreement.

instrument in writing signed by or on behalf of all the partieshereto.

       11.3. WAIVER. Each of Seller and Buyer may (a) waive any

contained herein or in any document, certificate, or writing delivered
pursuant hereto or (b) waive compliance by the other with any of the

obligations contained herein. Any agreement on the part of a party

                                  38
<PAGE>

instrument in writing signed by or on behalf of such party. No failure
or delay by a party hereto in exercising any right, power, or
privilege hereunder shall operate as a waiver thereof nor shall any
single or partial exercise thereof preclude any other or further
exercise thereof or the exercise of any other right, power, or
privilege.


           XII. SURVIVAL OF REPRESENTATIONS; INDEMNIFICATION

       12.1. SURVIVAL. The representations, and warranties of the
parties hereto contained in this Agreement or in any certificate,
instrument, or document delivered pursuant hereto and the covenants of
the parties shall not survive the Closing, regardless of any
investigation made by or on behalf of any party, except as hereinafter

Environmental Claim (as defined below), in which case such
representations and warranties shall survive until the fifth
anniversary of the Closing Date, (b) the representations and
warranties of Seller and Buyer contained in SECTIONS 5.23 and 6.8
shall survive until the expiration of the limitation period under the
applicable statute of limitations, (c) the representations and

7.26 shall survive the Closing Date (each such anniversary and time of
expiration, if any, a "SURVIVAL DATE"). From and after a Survival
Date, no party hereto or any shareholder, director, officer, employee,
or affiliate of such party shall be under any liability whatsoever
(whether pursuant to this SECTION 12.1 or otherwise with respect to
any representation, warranty or covenant to which such Survival Date
relates unless before the Survival Date for such representation or
warranty it shall have received from the party seeking indemnification
written notice of the existence of the claim for or in respect of
which indemnification is sought. Such notice shall set forth with
reasonable specificity, to the extent then known (i) the basis under
this Agreement, and the facts that otherwise form the basis, of such
claim, (ii) an estimate of the amount of such claim (which estimate
shall not be conclusive of the final amount of such claim) and an
explanation of the calculation of such estimate, including a statement
of any significant assumptions employed therein, and (iii) the date on
and manner in which the party delivering such notice became aware of
the existence of such claim. As used herein, "ENVIRONMENTAL CLAIM"
shall mean any claim, action, suit or proceeding made, brought or
filed, as the case may be, by a Governmental Entity or other third
party against Buyer, arising out of or relating to a condition
existing as of the Closing or an event occurring prior to the Closing
that is in contravention of or in breach of any of the representations
and warranties made by Seller in SECTION 5.22 as of the date hereof or
as of the Closing.

       12.2. INDEMNIFICATION BY SELLER. Subject to the terms and
conditions of this ARTICLE XII, Seller shall indemnify, defend, and

damages, liabilities, judgments, settlements, penalties, costs, and

nature whatsoever (collectively, "DAMAGES"), asserted against,

               (a) any inaccuracy in or breach of any representation
          or warranty of Seller contained in this Agreement which
          survives the Closing Date;

               (b) any breach by Seller of any of its covenants or
          agreements contained in this Agreement which survives the
          Closing Date;

               (c) any claim, action or proceeding made or brought by
          a third party arising out of or attributable to the
          ownership or operation of the Properties prior to the
          Closing Date (other than matters covered in the
          representations of Seller in SECTION 5.9 and described in
          CLAUSE (D) below) and then only if Buyer gives notice to
          Seller of the claim of Buyer for such indemnification prior
          to the second anniversary of the Closing Date; and

               (d) any Environmental Claim.

hold harmless Seller, its affiliates, their respective directors,
officers, employees, and agents, and each of the heirs, legal

(collectively, the "SELLER GROUP"), from and against any and all

any member of the Seller Group, directly or indirectly, by reason of
or resulting from:

               (a) any inaccuracy in or breach of any representation
          or warranty of Buyer contained in this Agreement which
          survives the Closing Date;

               (b) any breach by Buyer of any of its covenants or
          agreements contained in this Agreement which survives the
          Closing Date; and

               (c) any claim, action or proceeding made or brought by

                                  40
<PAGE>
       12.4. CERTAIN LIMITATIONS ON SELLER'S LIABILITY.
Notwithstanding anything in this ARTICLE XII or elsewhere in this
Agreement to the contrary:

          (a) No indemnification shall be required to be made by
     Seller pursuant to SECTIONS 12.2(A), (B) and (C), until and
     except to the extent that the aggregate amount of Damages
     thereunder exceeds $1,000,000.

          (b) The indemnification obligation of Seller under SECTION
     12.2(d) shall be subject to the following. No indemnification
     shall be required to be made by Seller pursuant to SECTION
     12.2(d), until and except to the extent that the aggregate amount
     of Damages thereunder exceeds $1,000,000 (the "THRESHOLD
     AMOUNT"). Thereafter, Seller shall be required to indemnify the
     Buyer Group for all Damages under SECTION 12.2(d) in excess of
     the Threshold Amount until that point in time when Seller has
     indemnified the Buyer Group for Damages in an aggregate amount
     equal to $2,000,000 (the "SPLIT POINT"). From and after the Split
     Point, Seller shall be required to indemnify the Buyer Group for
     (i) 75% of all Damages under SECTION 12.2(d), to the extent that
     Buyer gives notice to Seller of the claim of Buyer for such
     indemnification prior to the second anniversary of the Closing
     Date and (ii) 50% of all Damages under SECTION 12.2(d), to the
     extent that Buyer gives notice to Seller of the claim of Buyer
     for such indemnification on or after the second anniversary of
     the Closing Date but prior to the fifth anniversary of the
     Closing Date. Seller shall have no further liability under
     Environmental Laws with respect to the Oil and Gas Properties as
     to any claims in connection therewith arising after the fifth
     anniversary of the Closing Date.

          (c) The amount of Damages required to be paid by Seller to
     indemnify the Buyer Group pursuant to this ARTICLE XII shall be
     reduced to the extent of any amounts in excess of $1,000,000
     actually received by any member of the Buyer Group after the
     Closing Date pursuant to the terms of the insurance policies (if
     any) covering the subject claim.

       12.5. PROCEDURE FOR INDEMNIFICATION. Within ten days after
receipt by an indemnified party under SECTION 12.2 or 12.3 of notice
of the commencement of any action, such indemnified party shall, if a
claim in respect thereof is to be made against an indemnifying party
under such Section, give written notice to the indemnifying party of
the commencement thereof, but the failure so to notify the
indemnifying party shall not relieve it of any liability that it may
have to any indemnified party except to the extent the indemnifying
party demonstrates that the defense of such action is materially
prejudiced thereby. In case any such action shall be brought against
an indemnified party and it shall give written notice to the
indemnifying party of the commencement thereof, the indemnifying party
shall be entitled to participate therein and, to the extent that it
may wish, to assume the defense thereof with counsel reasonably
satisfactory to such indemnified party. If the indemnifying party
elects to assume the defense of such action,

                                  41
<PAGE>

the indemnified party shall have the right to employ separate counsel
at its own expense and to participate in the defense thereof. If the
indemnifying party elects not to assume (or fails to assume) the
defense of such action, the indemnified party shall be entitled to
assume the defense of such action with counsel of its own choice, at
the expense of the indemnifying party. If the action is asserted
against both the indemnifying party and the indemnified party and
there is a conflict of interests which renders it inappropriate for
the same counsel to represent both the indemnifying party and the
indemnified party, the indemnifying party shall be responsible for
paying for separate counsel for the indemnified party; provided,
however, that if there is more than one indemnified party, the
indemnifying party shall not be responsible for paying for more than
one separate firm of attorneys to represent the indemnified parties,
regardless of the number of indemnified parties. If the indemnifying
party elects to assume the defense of such action, (a) no compromise
or settlement thereof may be effected by the indemnifying party
without the indemnified party's written consent (which shall not be
unreasonably withheld) unless the sole relief provided is monetary
damages that are paid in full by the indemnifying party and (b) the
indemnifying party shall have no liability with respect to any
compromise or settlement thereof effected without its written consent
(which shall not be unreasonably withheld).


                 XIII. CASUALTY LOSS AND CONDEMNATION

       If after the Effective Date and prior to the Closing, any part
of the Properties shall be destroyed by fire or any other cause (but
not to a substantial extent) or shall be taken by condemnation or the
exercise of eminent domain (but not to a substantial extent), then if
Closing occurs, Seller shall pay at Closing to Buyer all proceeds of
insurance or condemnation (to the extent then received and not subject
to payment or reimbursement by Seller or its affiliates) which were
paid in respect of such loss or taking; if any proceeds of insurance
or condemnation, to the extent not subject to payment or reimbursement
by Seller or its affiliates, are received by Seller after the Closing,
Seller shall promptly tender such proceeds to Buyer. In the event that
either so much of the Properties are damaged or destroyed by fire or
other event or taken by condemnation or purchase in lieu thereof,
after the Effective Date but before the Closing, to the extent that
the value allocated to all those Properties so affected, as set forth
on SCHEDULE A, exceeds $5,000,000, then the Properties shall be deemed
to have been destroyed or harmed to a substantial extent for the
purpose of this ARTICLE XIII. If the Properties are destroyed or
harmed to a substantial extent as above described, then Buyer shall
have the right to elect either (a) to close this transaction as if the
Properties had not been destroyed or harmed to a substantial extent,
whereupon Seller shall make the payments described in the first
sentence of this ARTICLE XIII, or (b) to terminate this Agreement,
whereupon Seller and Buyer shall be released and relieved of all
further obligation hereunder, as provided in ARTICLE XI.

                  XIV. CERTAIN ACCOUNTING ADJUSTMENTS


      14.1. ADJUSTMENTS. Except as otherwise provided herein, (x) all
costs and revenues attributable to the Properties and the operations
thereon prior to the Effective Date shall be the obligation of and for
the benefit of Seller and (y) all costs and revenues attributable to
the Properties and the operations thereon after the Effective Date
shall be the obligation of and for the benefit of Buyer. The Purchase
Price shall be adjusted upward by the following: (i) the value of all
merchantable, allowable oil in storage on the Effective Date at the
location of each Property that is credited to the Property, based upon
the actual prices being paid less the cost of transportation, however
paid, and less taxes and other expenses, if any, deducted by the
purchaser of the oil; and (ii) the amount (less amounts which have
been collected from others in reimbursement of the following direct
expenditures) of all actual expenditures of Seller (including
royalties, delay rentals and other charges, and ad valorem, property,
production, excise, severance, windfall profit and other taxes (other
than income taxes), based upon or measured by the ownership of
property or the production of Hydrocarbons or the receipt of proceeds
therefrom), expenses, including drilling and completion expenses,
billed under applicable operating agreements and, in the absence of an
operating agreement, expenses of the sort customarily billed under
such agreements, but excluding any of Seller's or any of its
affiliate's overhead and administrative expenses or office lease
expenses, paid by or on behalf of Seller and to the extent, in
accordance with generally accepted accounting principles, in
connection with the Properties in the ordinary course of business
after the Effective Date, plus an amount calculated at the rate of
$40,000 per month to the Closing as the sole compensation to Seller
for its overhead and administrative expenses and office lease expenses
in connection with supervising the Properties, plus the amount of any
expenditures attributable to the Oil and Gas Properties prior to the
Effective Date with respect to the projects or other activities listed
on SCHEDULE 14.1 or hereafter approved by Buyer.

      The Purchase Price shall be adjusted downward by the following:
(A) the proceeds received by Seller in connection with the Properties
to the extent, in accordance with generally accepted accounting
principles, attributable to the period after the Effective Date,
including income resulting from combined fixed rate overhead charges
under applicable operating agreements and the proceeds received by
Seller from the disposition after the Effective Date (with or without
the prior consent from Buyer as provided in SECTION 7.1) of all or any
portion of the Properties; (B) an amount equal to all ad valorem,
property, production, excise, severance, windfall profit and similar
taxes and assessments (but not including income taxes) based upon or
measured by the ownership of property or the production of
Hydrocarbons or the receipt of proceeds therefrom accruing or relating
to the Properties prior to the Effective Date to the extent not paid
by Seller before the Closing Date and thereafter assumed by Buyer; (C)
the amount of all actual direct expenditures of Seller (including
royalties, rentals and other charges, expenses, including drilling and
completion expenses, billed under applicable operating agreements and,
in the absence of an operating agreement, expenses of the sort
customarily billed under such

                                  43
<PAGE>

agreements), that are, in accordance with generally accepted
accounting principles, attributable to the ownership or the operation
of the Properties before the Effective Date, to the extent not paid by
the Seller before the Closing Date and thereafter assumed by Buyer;
(D) all amounts collected by Seller as operator (or otherwise) from
other working interest owners attributable to such parties' shares of
the costs and expenses of an operation or operations after the
Effective Date for which (and to the extent) Seller has not yet
actually paid such costs and expenses; and (E) the proceeds received
by Seller in connection with the Properties described in SCHEDULE 14.1
attributable to the period prior to the Effective Date.

       14.2. ACCOUNTING. No later than 15 days prior to Closing,
Seller shall furnish Buyer with an estimated accounting showing in
reasonable detail the adjustments described in and subject to SECTION
14.1. If pursuant to such estimated accounting either Seller or Buyer
shall owe any obligation to the other, then the Cash Portion of the
Purchase Price paid at Closing shall be adjusted to reflect such
charges and credits which are necessary to accomplish such adjustment.
Promptly after the Closing Date (but not later than one hundred eighty
(180) days thereafter), Seller shall furnish Buyer with a final
accounting showing in reasonable detail the adjustments described in
and subject to SECTION 14.1. For a period of 90 days following receipt
by Buyer of such accounting, Seller shall provide Buyer and its
representatives with access to all records reasonably required to
compute all adjustments pursuant to this ARTICLE XIV. If within ninety
(90) days after Seller furnishes such final accounting to Buyer, Buyer
and Seller are unable to agree on such final accounting, then either
Seller or Buyer may submit such dispute to the accounting firm of
Arthur Andersen & Co. and the determination made as to such dispute by
such accounting firm shall be final and binding upon Seller and Buyer.
Final settlement shall be made within thirty (30) days following
agreement by the Buyer and Seller or final determination by said
accounting firm. The fees charged by said accounting firm for making
determinations under this SECTION 14.2 shall be paid one-half (1/2) by
Buyer and one-half (l/2) by Seller. The parties agree that if actual
ad valorem taxes on the Oil and Gas Properties for a particular state
for calendar year 1993 are still not known at the time of the final
accounting, appropriate adjustments consistent with SECTION 14.1 will
be made to reflect such actual ad valorem taxes after the final
accounting, provided such adjustments are made within one year after
the Closing.

     This Amended and Restated Revolving Credit Agreement (as amended,
modified, supplemented and restated from time to time, this
"AGREEMENT") dated as of March 16, 1994, is by and among SANTA FE
ENERGY RESOURCES, INC. (the "COMPANY"), a Delaware corporation; each
of the lenders which is or which may from time to time become a
signatory hereto (individually a "BANK" and collectively the "BANKS");
TEXAS COMMERCE BANK NATIONAL ASSOCIATION ("TCB"), a national banking

together with its successors in such capacity, the "AGENT"); and TCB
and NATIONSBANK OF TEXAS, N.A. ("NATIONSBANK"), a national banking
association, as Co-Agents (in such capacity, the "CO-AGENTS").

INTRODUCTION.

     The Company, the Banks, the Agent and the Co-Agents entered into
that certain Revolving and Term Credit Agreement dated as of May 20,
1992.  They now wish to amend and restate that agreement as it has
been amended prior to the date hereof.

AGREEMENTS.

     The parties agree as follows:

     Section 1.  DEFINITIONS AND ACCOUNTING MATTERS.

     1.1. CERTAIN DEFINED TERMS.  As used herein, the following terms
shall have the following meanings:

     "ACHIEVEMENT DATE" shall mean the first date on which both (a)
the aggregate minimum Qualifying Amount of Junior Securities to be
used in determining the applicable table on EXHIBIT E for the Facility
A Maximum Amount and the applicable table on EXHIBIT F for the
Preliminary Available Amount has been issued and the gross proceeds
thereof received by the Company and (b) all Designated Debt for the
aggregate Qualifying Amount of Junior Securities actually issued, as
shown on SCHEDULE X, shall have been repaid or Defeased.  In
determining any Achievement Date, the Qualifying Amounts of Junior
Securities issued on such date, on the Qualifying Date and on each
additional date, if any, on which Junior Securities have been issued
shall be aggregated.  For example, if there is only one issuance of
Junior Securities and such issuance is in a Qualifying Amount of
$75,000,000, the Facility A Maximum Amount will thereafter be

<PAGE>

determined according to Table Four of EXHIBIT E, the Preliminary
Available Amount will thereafter be determined according to Table Four
of EXHIBIT F, and the Qualifying Date and the Achievement Date will be
the same.  For example, if there are two issuances of Junior
Securities, one in the amount of $75,000,000 and a later one in the
amount of $50,000,000, the Qualifying Date will be the date of the
first issuance, which will also be the Achievement Date for the
$75,000,000 level in both EXHIBIT E and EXHIBIT F, and the Facility A
Maximum Amount will be determined according to Table Four of EXHIBIT E
and the Preliminary Available Amount will be determined according to
Table Four of EXHIBIT F until the date of the second issuance; the
date of the second issuance will be the Achievement Date for the
$125,000,000 level in both EXHIBIT E and EXHIBIT F, and the Facility A
Maximum Amount will thereafter be determined according to Table Two of
EXHIBIT E and the Preliminary Available Amount will thereafter be
determined according to Table Two of EXHIBIT F.  An Achievement Date
must occur, if at all, prior to July 1, 1994.

     "ADDITIONAL COSTS" shall have the meaning ascribed to such term
in SECTION 6.1.

     "ADOBE" shall mean Adobe Resources Corporation, formerly a
Delaware corporation.

     "ADOBE PROPERTIES" shall mean oil, gas and mineral properties and
other assets owned by Adobe at the time of the Merger.

directly or indirectly controls, or is under common control with, or
is controlled by, such Person; and with respect to an individual,
"AFFILIATE" shall also mean any individual related to such individual
by blood or marriage.  As used in this definition, "CONTROLS",
"CONTROLLED BY" and "UNDER COMMON CONTROL WITH" shall mean possession,

     Section 2.  COMMITMENTS.

     2.1. LOANS.  Each Bank severally agrees, subject to the terms and
conditions of this Agreement, to make Loans as follows:

     (a)  FACILITY A LOANS.

          (1)  On the date hereof, each Bank shall make to the Company
(and the Company shall borrow from each Bank) a Loan under this
SECTION 2.1(a) in an amount not to exceed such Bank's Facility A
Commitment then in effect. The aggregate of the Facility A Commitments
on the date hereof is $90,000,000.

          (2)  From time to time after the date hereof and prior to
the Facility A Termination Date, each Bank shall readvance Facility A
Optional Prepayments under this SECTION 2.1(a) to the Company in an
aggregate principal amount at any one time outstanding up to but not
exceeding such Bank's Commitment Percentage of the Facility A  Unused
Commitment then in effect.  Each Facility A Readvance shall be in an
amount that is an integral multiple of $1,000,000.  Subject to the
conditions herein, any such Facility A Optional Prepayment made prior
to the Facility A Termination Date may be reborrowed pursuant to the
terms of this Agreement; PROVIDED, that any and all Facility A Loans
shall be due and payable in full at the Facility A Maturity Date.

          (3)  Notwithstanding anything in this Agreement to the
contrary, (A) no Bank shall be required to make any Facility A
Readvance if by virtue thereof the aggregate of the Facility A
Readvances of such Bank at any one time outstanding would exceed such
Bank's Commitment Percentage of the Facility A Unused Commitment then
in effect, and (B) if a Bank fails to make a Facility A Readvance as
and when required hereunder and the Company subsequently makes a
repayment on the Facility A Notes, such repayment shall be split among
the non-defaulting Banks ratably in accordance with their respective
Commitment Percentages until each Bank has its Commitment Percentage
of all of the outstanding Facility A Loans, and the balance of such
repayment shall be divided among all of the Banks in accordance with
their respective Commitment Percentages. 

          (4)  Notwithstanding anything in this Agreement to the
contrary, no Bank shall be required to make a Facility A Readvance
(but each Bank shall permit Rollovers) during the existence of an
Engineering Shortfall.

                                 -42-
<PAGE>

     (b)  FACILITY B LOANS.

          (1)  Subject to the conditions herein (including CLAUSE (6)
of this section), from time to time on or after the date hereof and
prior to the Facility B Termination Date, each Bank shall make Loans
under this SECTION 2.1(b) to the Company in an aggregate principal
amount at any one time outstanding up to but not exceeding such Bank's
Facility B Commitment; PROVIDED HOWEVER, that the foregoing
notwithstanding, prior to the Qualifying Date or, if no Qualifying
Date occurs, July 1, 1994, the aggregate Facility B Loans shall never
exceed the aggregate of the Facility B Commitments of all Banks minus
the Unavailable Commitment.  Subject to the conditions herein
(including CLAUSE (6) of this section), any such Facility B Loan
repaid prior to the Facility B Termination Date may be reborrowed
pursuant to the terms of this Agreement; PROVIDED, that any and all
such Facility B Loans shall be due and payable in full on the
Facility B Maturity Date.

          (2)  Concurrently with the delivery of each Independent
Engineering Report and related Coverage Report required or permitted
hereby, there shall be determined, based on the Most Recent
Engineering Report and Approved Assumptions, the total maximum amount
of Facility B Loans and Letters of Credit to be available to the
Company hereunder and under the Letter of Credit Agreement without
violation of any Required Ratio.  Upon each such delivery, the Company
may by notice to the Co-Agents designate as the Available Amount any
amount (not to exceed the Preliminary Available Amount as of the most
recent Achievement Date (or, if no Achievement Date occurs, the
Preliminary Available Amount then in effect) according to the
applicable table in EXHIBIT F) equal to or less than such total
maximum amount.  The Available Amount so designated shall remain in
effect as the Available Amount until the next determination under this
SECTION 2.1(b)(2).  If no amount lesser than (a) or (b) in this
sentence is designated in accordance with this SECTION 2.1(b)(2), the
Available Amount shall be the lesser of (a) the Preliminary Available
Amount then in effect according to the applicable table in EXHIBIT F
or (b) such total maximum amount.

          (3)  Notwithstanding anything in this Agreement to the
contrary, (A) no Bank shall be required to make Facility B Loans at
any one time outstanding in excess of such Bank's Commitment
Percentage of the lesser of (x) the aggregate of the Facility B
Commitments of all Banks then in effect (minus, prior to the
Qualifying Date or, if no Qualifying Date occurs, July 1, 1994, the
Unavailable Commitment) and (y) the difference between (i) the
Available Amount and (ii) the aggregate Letter of Credit Liabilities,
and (B) if a Bank fails to make a Facility B Loan as and when required
hereunder and the Company subsequently makes a 

                                 -43-
<PAGE>

repayment on the Facility B Notes, such repayment shall be split among
the non-defaulting Banks ratably in accordance with their respective
Commitment Percentages until each Bank has its Commitment Percentage
of all of the outstanding Facility B Loans, and the balance of such
repayment shall be divided among all of the Banks in accordance with
their respective Commitment Percentages.

          (4)  Notwithstanding anything in this Agreement to the
contrary, no Bank shall be required to make Facility B Loans (but each
Bank shall permit Rollovers) during the existence of an Engineering
Shortfall.

          (5)  Upon each delivery of the financial statements required
by SECTION 9.1(b) and the Independent Engineering Report required by
SECTION 9.1(g), the Company may request the Banks to extend the
Facility B Termination Date then in effect by a period not to exceed
one year (but in no event later than December 31, 1998).  Such request
shall be made by giving its written request to the Agent specifying
the date to which the Facility B Termination Date is to be extended. 
The Agent, the Co-Agents and the Banks shall consider any such request
in a timely fashion and in good faith and in light of all relevant
facts and circumstances at the time of such request, but the granting
of any such extension shall be at all times within the sole and
absolute discretion of the Agent, the Co-Agents and the Banks.  The
granting of any such extension would require the unanimous consent of
the Agent, the Co-Agents and the Banks and may be conditional on such
terms and conditions as the Agent, the Co-Agents and the Banks may in
their discretion propose.  Failure to obtain such an extension shall
not IPSO FACTO either constitute or excuse a Default or an Event of
Default.

          (6)  Notwithstanding anything contained in this Section,
except in the case of a Rollover or a Facility B Loan to satisfy a
Reimbursement Obligation pursuant to SECTION 4.1, the Company may not
obtain Facility B Loans at any time unless the Facility A Unused
Commitment is equal to zero at such time.

     2.2. TERMINATIONS, REDUCTIONS AND CHANGES OF COMMITMENTS AND
FACILITY A MAXIMUM AMOUNTS.

     (a)  MANDATORY.  (1)  On the Facility A Termination Date, all
Facility A Commitments shall be terminated in their entirety.  On the
Facility B Termination Date, all Facility B Commitments shall be
terminated in their entirety.

          (2)  In the event that the Company is required to make a
prepayment of the Facility A Loans pursuant to SECTION 3.2(b)(2)(A) or
3.2(b)(2)(B), the Facility A Maximum Amount for the Applicable 

                                 -44-
<PAGE>

Period then in effect shall be reduced by the amount of such
prepayment and an amount equal to such prepayment shall be deducted
from the Facility A Maximum Amounts for each subsequent Applicable
Period PRO RATA according to their respective amounts in effect
immediately prior to such reduction; PROVIDED, that if such PRO RATA
deduction does not result in compliance by the Company with all
Required Ratios, such amount shall be reallocated among such
subsequent Applicable Periods (and, if necessary, to the aggregate
Facility B Commitments) as the Company shall direct to the extent
necessary to bring the Company into compliance with all Required
Ratios.

          (3)  The Company shall from time to time reduce the
aggregate Facility B Commitments for present and future Applicable
Periods (and, if necessary, the Facility A Maximum Amount) to the
extent necessary to bring the Company into compliance with all
Required Ratios.  Any such reduction or termination of Commitments
shall be made against the Facility B Commitments; PROVIDED, that if
the Company can comply with all Required Ratios only by reducing the
Facility A Maximum Amount, the Company may reduce or terminate the
Facility A Maximum Amount, but only to the extent necessary to achieve
such compliance.  Any such reduction shall be accomplished within 10
Business Days after demand therefor by the Agent; PROVIDED, that in
the case of any noncompliance with Required Ratios resulting solely
from an Engineering Shortfall, the Company shall remedy such
noncompliance, but no Event of Default shall occur until the
expiration of the cure period provided in SECTION 10.1(e).

          (4)  In addition, in the event the Company is required to
make a prepayment of Facility A Loans pursuant to SECTION 3.2(b)(3),
an amount equal to such prepayment shall be deducted from the Facility
A Maximum Amounts for present and future Applicable Periods (and, if
necessary, to the aggregate Facility B Commitments) in such manner as
the Company may direct to the extent necessary to bring the Company
into compliance with all Required Ratios.

          (5)  Except where reductions in the Facility A Maximum
Amounts for the Applicable Periods are made PRO RATA pursuant to
SECTION 2.2(a)(2), if at any time the Facility A Maximum Amount is
reduced for any future Applicable Period pursuant to
SECTION 2.2(a)(2), 2.2(a)(3) or 2.2(a)(4) to bring the Company in
compliance with all Required Ratios, the Facility A Maximum Amount for
the Applicable Period in effect at such time and each Applicable
Period subsequent thereto and prior to such future Applicable Period
shall be reduced by a like amount.

                                 -45-
<PAGE>

     (b)  THE COMPANY'S OPTION.

          (1)  The Company shall have the right to terminate or reduce
the unused portion of the Facility B Commitments at any time or from
time to time; PROVIDED that (A) the Company shall give notice of each
such termination or reduction to the Agent as provided in SECTION 5.5;
(B) each such partial reduction shall be in an integral multiple of
$5,000,000, and (C) the Company may not cause the Available Amount to
be less than the aggregate principal amount of the Facility B Loans
then outstanding plus the Letter of Credit Liabilities then
outstanding.  No voluntary reduction in the Available Amount prior to
any scheduled reduction in the Available Amount shall affect the
Available Amount after such scheduled reduction date unless such
voluntarily reduced Available Amount is less than the amount scheduled
to be the Available Amount after such scheduled reduction date, in
which case the Available Amount after such scheduled reduction date
shall be no greater than such voluntarily reduced Available Amount. 
Reference is made to SECTION 2.8 for restrictions on the Company's
right to increase the Available Amount under certain circumstances.

          (2)  The Company shall have the right to (A) terminate or
reduce the Facility A Unused Commitment at any time or from time to
time or (B) reduce the Facility A Maximum Amount for any particular
Applicable Period at any time or from time to time; PROVIDED that (i)
the Company shall give notice of each such termination or reduction to
the Agent as provided in SECTION 5.5, (ii) each such partial reduction
shall be in an integral multiple of $5,000,000, (iii) the Company may
not cause the Facility A Maximum Amount to be less than the aggregate
principal amount of the Facility A Loans then outstanding; and (iv)
the Company shall not terminate or reduce the Facility A Unused
Commitment unless at the same time the aggregate Facility B
Commitments are terminated or reduced by the same amount.  Reductions
in the Facility A Maximum Amount may be applied to any Applicable
Period at the option of the Company PROVIDED that after such
application the Company is in compliance with all Required Ratios.  

     (c)  NO REINSTATEMENT.  NO reduction in or termination of the
Commitments pursuant to SECTION 2.2 and no reduction in any Facility A
Maximum Amount may be reinstated without the written approval of the
Agent and all Banks.

     2.3. FEES.  (a) In consideration of the Commitments, the Company
shall pay to the Agent for the account of each Bank in accordance with
its Commitment Percentage commitment fees (the "COMMITMENT FEES") for
the period from the date of the effectiveness of this Agreement to and
including the date the last of the Commitments are terminated at a
rate per annum equal to the 

                                 -46-
<PAGE>

sum of (a) 1/2% of the unused portion of the Available Commitment and
(b) 1/4% of the Unavailable Commitment.  The Commitment Fees shall be
computed for each day and shall be based on the unused portion of the
Available Commitment and the Unavailable Commitment for such day. 
Accrued Commitment Fees shall be payable in arrears on the date of the
initial Loans or Facility A Readvances, within three days after demand
therefor on or about the Quarterly Dates, and within three days after
demand therefor on or about the relevant Termination Date.  

     (b)  In consideration of the Commitments and of the agreement of
the Banks to enter into this Agreement, the Company shall pay to the
Agent for the account of each Bank in accordance with its Commitment
Percentage a facility fee in an amount equal to .125% of such Bank's
Commitment Percentage of the Unavailable Commitment.  Such facility
fee shall be due on the Qualifying Date and will never be due if the
Qualifying Date does not occur.  

     (c) All past due fees payable pursuant to this section shall bear
interest at the Post-Default Rate.  Upon receipt, the Agent shall
disburse such fees to the Banks in accordance with their Commitment
Percentages.

     2.4. AFFILIATES; LENDING OFFICES.

     (a)  Any Bank may, if it so elects, fulfill its Commitment as to
any Eurodollar Loan by causing a branch, foreign or otherwise, or
Affiliate of such Bank to make such Loan and may transfer and carry
such Loan at, to or for the account of any branch office or Affiliate
of such Bank; PROVIDED that in such event, for the purposes of this
Agreement, such Loan shall be deemed to have been made by such Bank
and the obligation of the Company to repay such Loan shall
nevertheless be to such Bank and shall be deemed to be held by such
Bank, to the extent of such Loan, for the account of such branch or
Affiliate.

     (b)  Notwithstanding any provision of this Agreement to the
contrary, each Bank shall be entitled to fund and maintain its funding
of all or any part of its Loans hereunder in any manner it sees fit,
it being understood, however, that for the purposes of this Agreement
all determinations hereunder shall be made as if such Bank had
actually funded and maintained each Eurodollar Loan during each
Interest Period through the purchase of deposits having a maturity
corresponding to such Interest Period and bearing an interest rate
equal to the applicable Eurodollar Base Rate for such Interest Period.

     2.5. SEVERAL OBLIGATIONS.  The failure of any Bank to make any
Loan to be made by it on the date specified therefor shall not 

                                 -47-
<PAGE>

relieve any other Bank of its obligation to make its Loan on such
date, but neither the Agent nor any Bank shall be responsible for the
failure of any other Bank to make a Loan to be made by such other
Bank.

     2.6. NOTES.  The Loans made by each Bank shall be evidenced by a
single Facility A Note or Facility B Note, as the case may be, of the
Company (each, together with all renewals, extensions, modifications
and replacements thereof and substitutions therefor, a "NOTE") dated
the date hereof, payable to the order of such Bank in a principal
amount equal to the Commitment of such Class of such Bank as
originally in effect and otherwise duly completed.  Each Bank is
hereby authorized by the Company to endorse on the schedule (or a
continuation thereof) attached to each Note of such Bank, to the
extent applicable, the date, amount and Type of and the Interest
Period for each Loan made by such Bank to the Company hereunder, and
the amount of each payment or prepayment of principal of such Loan
received by such Bank; PROVIDED that any failure by such Bank to make
any such endorsement shall not affect the obligations of the Company
under such Note, in respect of such Loan, or hereunder.

     2.7. OPTIONAL RESERVE REPORT.  The Company may from time to time
at its option, exercisable by giving written notice to the Co-Agents
not more often than once in any Calculation Period, provide to the
Co-Agents an Independent Engineering Report.  Upon the receipt of such
notice, the Co-Agents shall consult with the Company to determine new
Approved Assumptions, which shall be furnished to the Banks by a
notice as provided in the definition of "Approved Assumptions" and
shall be subject to the approval by Banks with aggregate Commitment
Percentages of 75% or more as provided therein.  The Optional Reserve
Report shall be based on the new Approved Assumptions and shall be
accompanied by a Coverage Report as of the date such Optional Reserve
Report is furnished.  The Annual Debt Service Coverage Ratio, the
Alternate Annual Debt Service Coverage Ratio, the TLOR Coverage Ratio
and the SLOR Coverage Ratio (and the Applicable Margin) shall each be
redetermined in accordance with this Agreement on the basis of each
such Optional Reserve Report and Coverage Report, and the Available
Amount recalculated as provided in SECTION 2.1(b)(2). 

     2.8. RELEASE OF MORTGAGES.  The Company shall be entitled to a
release of the Mortgaged Properties from the liens, assignments and
security interests of the Deed of Trust and the other Mortgages,
PROVIDED that (a) immediately before and immediately after giving
effect to such release, no Default shall have occurred and be
continuing; and (b) the Annual Debt Service Coverage Ratio and the
SLOR Coverage Ratio (each calculated assuming the Available Amount is
fully drawn and that the aggregate unpaid principal 

                                 -48-
<PAGE>

balance of the Facility A Notes is equal to the Facility A Maximum
Amount) immediately before and immediately after giving effect to any
such release shall be at least 1.25 to 1.00 and 2.00 to 1.00,
respectively.  At any time on or after the Qualifying Date, but prior
to July 1, 1994, the Company may choose not more often than once by
giving written notice to the Co-Agents to recalculate the Annual Debt
Service Coverage Ratio and the SLOR Coverage Ratio to determine if the
Company qualifies for release of the Mortgaged Properties pursuant to
this section; such recalculation shall be based on new Approved
Assumptions to be determined in connection with such recalculation by
Banks with Commitment Percentages of 75% or more and using the
Independent Engineering Report most recently furnished in accordance
with this Agreement.  Notwithstanding any other provision of this
Agreement to the contrary, should both (x) the Company at any time
designate as the Available Amount an amount less than the maximum
amount then offered to it as the Available Amount and (y) as a result
the Company shall obtain the release of any Mortgaged Properties, the
Available Amount may never thereafter exceed the amount so designated
by the Company.

     2.9. USE OF PROCEEDS.  The proceeds of the Loans shall be used by
the Company for working capital and for general corporate purposes and
may not be utilized (a) to pay dividends other than usual dividends in
the ordinary course of business or (b) for the buyout or acquisition
of any business unless the board of directors of such Person or any
other similar body has first approved such buyout or acquisition.

     2.10.     ORIGINAL CREDIT DOCUMENTS NOT TERMINATED.  The
execution and delivery of this Agreement and the other Credit
Documents in connection with this Agreement, including the Notes, does
not and shall not constitute payment, prepayment or novation of any
indebtedness outstanding under the Revolving and Term Credit Agreement
dated as of May 20, 1992, by and among the parties hereto, as amended,
or the notes outstanding thereunder on the date hereof (the "ORIGINAL
NOTES").  The Original Notes have been marked "renewed" rather than
"paid".  All Liens securing the Original Notes as amended and modified
from time to time by the Credit Documents executed and delivered
concurrently with this Agreement are hereby ratified, confirmed,
extended, renewed and brought forward as security for the Notes and
all other Obligations of the Company described therein as being
secured thereby.

     2.11.     SALE OF CERTAIN PROPERTIES.  Notwithstanding the
provisions of SECTIONS 2.2, 2.8 and 3.2, the sale of the properties by
the Company pursuant to the agreement dated December 2, 1993 by and
among the Company, Santa Fe Energy Operating Partners, L.P. and Bridge

                                 -49-
<PAGE>

agreement dated October 26, 1993, by and among the Company, Santa Fe
Energy Operating Partners, L.P., Santa Fe Oil Company and Vintage
Petroleum, Inc. shall be made with a release from the Liens of the
Security Documents, without any required prepayment and without
reducing either any Facility A Maximum Amount or any Preliminary
Available Amount.

     Section 3.  BORROWINGS, PREPAYMENTS AND SELECTION OF INTEREST
RATES.

     3.1. BORROWINGS.  The Company shall give the Agent notice of each
borrowing to be made hereunder as provided in SECTION 5.5.  Each
borrowing shall be in an amount of $1,000,000 or any integral multiple
thereof.  Not later than 1:00 p.m. on the date specified for each such
borrowing hereunder, each Bank shall make available the amount of the
Loan, if any, to be made by it on such date to the Agent, at its
Principal Office, in immediately available funds, for the account of
the Company.  The amount so received by the Agent shall, subject to
the terms and conditions of this Agreement, be made available to the
Company by depositing the same, in immediately available funds, in an
account designated by the Company and maintained with the Agent at its
Principal Office.

     3.2. PREPAYMENTS.

     (a)  OPTIONAL PREPAYMENTS.  Except as provided in SECTIONS 3,
4.2(c), 5 and 6, the Company shall have the right to prepay, on any
Business Day, in whole or in part, without the payment of any penalty
or fee, Loans at any time or from time to time; PROVIDED that the
Company shall give the Agent notice of each such prepayment as
provided in SECTION 5.5.  Eurodollar Loans may be prepaid on the last
day of an Interest Period applicable thereto.  Eurodollar Loans may
not be otherwise prepaid unless prepayment is accompanied by payment
of all compensation required by SECTION 6.5.  All optional prepayments
shall be applied to Facility B Loans and Reimbursement Obligations
until all such Facility B Loans and Reimbursement Obligations have
been repaid, then to Facility A Loans.

     (b)  MANDATORY PREPAYMENTS.  (1) The Company shall from time to
time on demand by the Agent prepay the Facility B Loans in such
amounts as shall be necessary (A) so that at all times the aggregate
outstanding principal amount of the Facility B Loans and Letter of
Credit Liabilities shall not be in excess of the Available Amount or
(B) to comply with SECTION 9.9.  Any such payment shall be allocated
between Facility B Loans and Letter of Credit Liabilities and, if to
Letter of Credit Liabilities, first to Reimbursement Obligations and
then to other obligations as the Company may elect.

                                 -50-
<PAGE>
     In addition, the Company shall from time to time on demand by the
Agent prepay the Facility A Loans in such amounts as shall be
necessary (A) so that at all times the aggregate outstanding principal
amount of the Facility A Loans (including Facility A Readvances) shall
not be in excess of the Facility A Maximum Amount or (B) to comply
with SECTION 9.9.  


          (2)  (A) Upon any sale for cash or cash equivalent
consideration of any Proved Reserves included in the Adobe Properties
in excess of $1,000,000 in any one transaction or $5,000,000 for all
transactions, the Company shall prepay on the Business Day following
the date of such sale for application to the unpaid principal balance
of the Facility A Notes an amount equal to the greater of (i) 100% of
the total proceeds of such sale or (ii) 58% of the present worth
assigned to the property sold in the Most Recent Engineering Report.

               (B)  Except as otherwise permitted by the Mortgages,
Mortgaged Properties cannot be sold for consideration other than cash
without the approval of all Banks.  Upon any sale of any Proved
Reserves included in the Adobe Properties (other than Mortgaged
Properties) for consideration other than cash which causes the
aggregate net present value (at the discount rate included in the
Approved Assumptions on the date of each such sale) of all Adobe
Properties sold for consideration other than cash (determined in
accordance with the applicable Most Recent Engineering Report) in any
one Calculation Period to exceed $5,000,000, the Company shall prepay
on the Business Day following the date of such sale for application to
the unpaid principal balance of the Facility A Notes an amount equal
to 100% of the net present value (at the discount rate included in the
Approved Assumptions in effect on the date of such sale) of the Adobe
Properties so sold (determined in accordance with the Most Recent
Engineering Report).

               (C)  All amounts prepaid pursuant to
SECTION 3.2(b)(2)(A) or (B) shall be applied to the unpaid principal
balance of the Facility A Notes.  The Company may in its discretion
defer making the prepayment required by SECTION 3.2(b)(2) (A) or (B)
until the earlier of (i) the time the aggregate amount of such
prepayments so deferred equals or exceeds $1,000,000 or (ii) one month
after the date the first such prepayment would otherwise be due.

          (3)  Concurrently with any sale of any Proved Reserves
(whether or not included in the Adobe Properties) which would cause
the aggregate amount of such sales since the effective date of the
last calculation of compliance with the Required Ratios to exceed

                                 -51-
<PAGE>

$20,000,000 in the aggregate, each of the Annual Debt Service Coverage
Ratio and the Alternate Annual Debt Service Coverage Ratio shall be
redetermined for the Calculation Period in which such sales occur and
for each Calculation Period thereafter to and including December 31,
1998 and the SLOR Coverage Ratio and the TLOR Coverage Ratio shall be
redetermined, in each case to the effective date of the sale on the
basis of the most recent Approved Assumptions and the Most Recent
Engineering Report and the most recent Coverage Report delivered to
the Agent pursuant to SECTION 9.1.  In making such redeterminations,
(a) the Proved Reserves (whether or not included in the Adobe
Properties) described in the Most Recent Engineering Report which are
no longer owned by members of the Combined Group (the "SOLD
PROPERTIES") shall be identified; (b) there shall be determined the
gross and net volumes of Hydrocarbons projected in the Most Recent
Engineering Report to be produced from the Petroleum Properties
(including the Sold Properties) minus the gross and net volumes of
Hydrocarbons projected in the Most Recent Engineering Report to be
produced from the Sold Properties; (c) there shall be determined by
calendar years the Net Oil and Gas Income shown in the Most Recent
Engineering Report as attributable to the Petroleum Properties
(including the Sold Properties) of members of the Combined Group minus
the Net Oil and Gas Income shown in the Most Recent Engineering Report
as attributable to the Sold Properties; and (d) the discount rate and
other factors set forth in the most recent Approved Assumptions shall
be used.  In addition to any prepayments required by SECTION
3.2(b)(2)(A) and (B), if the Company upon any such redetermination
shall not be in compliance with all Required Ratios, the Company shall
prepay on the Business Day following the date of such sale an amount
of the proceeds of all sales of any Adobe Properties not previously
prepaid for application to the unpaid principal balance of the
Facility A Notes.  The Company may in its discretion defer making the
prepayments required by the preceding sentence until the earlier of
(a) the time the aggregate amount of such prepayments so deferred
equals or exceeds $1,000,000 or (b) one month after the date the first
such prepayment would otherwise be due.

          (4)  The Company shall maintain records of all sales of
Proved Reserves, shall clearly designate each such sale as a sale of
an Adobe Property or other property, and shall otherwise maintain
books and records which enable it to comply, and to demonstrate to the
Agent on request compliance, with the obligations of the Company in
this SECTION 3.2(b).

     3.3. SELECTION OF INTEREST RATES.  Subject to SECTIONS 5, 6 and
12.8, the Company shall have the right, by giving written notice to
the Agent as provided in SECTION 5.5, either to convert any Loan (in
whole or in part) into a Loan of another Type or to 

                                 -52-
<PAGE>

continue such Loan (in whole or in part) as a Loan of the same Type. 
Any such notice of conversion of a Loan into, or continuation of a
Loan as, a Eurodollar Loan shall specify the new Interest Period.  In
the event the Company fails to so give such notice prior to the end of
any Interest Period for any Eurodollar Loan, such Loan shall become an
Alternate Base Rate Loan on the last day of such Interest Period.  No
more than 10 Eurodollar Interest Periods shall be in effect at any
time.  Except as otherwise provided herein, each designation of an
interest rate with respect to the Facility A Notes or Facility B Notes
shall apply to all Facility A Notes and Facility B Notes ratably in
accordance with their respective outstanding principal balances.  If
any Bank assigns an interest in any of its Notes when any Eurodollar
Loan is outstanding with respect thereto, the assignee shall have its
ratable interest in such Eurodollar Loan.

     Section 4.  PAYMENTS OF PRINCIPAL AND INTEREST.

     4.1. REPAYMENT OF LOANS. (a) The Company will pay to the Agent
for the account of each Bank the principal of each Loan made by such
Bank on the dates provided in the respective Notes and herein and the
amount of each Reimbursement Obligation forthwith upon its incurrence. 
The amount of any Reimbursement Obligation may, if the applicable
conditions precedent specified in SECTION 7 (other than any Default
resulting solely from the nonpayment of such Reimbursement Obligation)
have been satisfied, be paid with the proceeds of Loans.

     (b)  Subject to SECTIONS 3.2 and 10.1, the Company shall pay the
outstanding principal amount of all Facility A Loans on the Facility A
Maturity Date and the outstanding principal amount of all Facility B
Loans on the Facility B Maturity Date.

     4.2. INTEREST.  (a) Subject to SECTION 12.8, the Company will pay
to the Agent for the account of each Bank interest on the unpaid
principal amount of each Loan made by such Bank for the period
commencing on the date of such Loan to but excluding the date such
Loan shall be paid in full, at the lesser of (1) the following rates
per annum:

     (A)  if such Loan is an Alternate Base Rate Loan, the Alternate
Base Rate PLUS the Applicable Margin for Alternate Base Rate Loans; or

     (B)  if such Loan is a Eurodollar Loan, the applicable Eurodollar
Rate PLUS the Applicable Margin for Eurodollar Loans; or

(2) the Highest Lawful Rate.

                                 -53-
<PAGE>

     (b)  Notwithstanding any of the foregoing but subject to
SECTION 12.8, the Company will pay to the Agent for the account of
each Bank interest at the applicable Post-Default Rate on any
principal of any Loan made by such Bank and on any other amount
payable by the Company hereunder to or for the account of such Bank
(but, if such amount is interest, only to the extent legally
enforceable), which shall not be paid in full when due (whether at
stated maturity, by acceleration or otherwise), for the period
commencing on the due date thereof through and including the date the
same is paid in full.  

     (c)  Accrued interest shall be due and payable on the applicable
Interest Payment Dates, except that (1) accrued  interest payable at
the Post-Default Rate shall be due and payable from time to time on
demand of the Agent or the Required Banks (through the Agent), (2)
accrued interest on any amount converted from one Type of Loan to
another Type of Loan shall be paid on the amount so converted at the
time of such conversion, and (3) accrued interest on any Eurodollar
Loan paid or prepaid shall be due at the time of such payment or
prepayment.  

     Section 5.  PAYMENTS; PRO RATA TREATMENT; COMPUTATIONS, ETC.

     5.1. PAYMENTS.  (a) Except to the extent otherwise provided
herein, all payments of principal of or interest on the Loans and
other amounts to be made by the Company hereunder and under the Notes
and the Security Documents shall be made in dollars, in immediately
available funds, to the Agent at its Principal Office (or in the case
of a successor Agent, at the principal office of such successor Agent
in the United States), not later than 11:00 a.m. on the date on which
such payment shall become due (each such payment made after such time
on such due date to be deemed to have been made on the next succeeding
Business Day).

     (b)  The Company shall, at the time of making each payment
hereunder or under any Note or any Security Document, specify to the
Agent the Loans or other amounts payable by the Company hereunder or
thereunder to which such payment is to be applied (and in the event
that it fails so to specify, such payment shall be applied as the
Agent may designate to the Loans or other amounts then due and
payable); PROVIDED that if no Loans are then due and payable or an
Event of Default has occurred and is continuing, the Agent may apply
such payment to the Obligations in such order as it may elect in its
sole discretion, but subject to the other terms and conditions of this
Agreement, including SECTION 5.2).  Each payment received by the Agent
hereunder or under any Note or any Security Document for the account
of a Bank shall be paid promptly to such Bank, in immediately
available funds for the account of such Bank's Applicable Lending
Office.

                                 -54-
<PAGE>

     (c)  If the due date of any payment hereunder or under any Note
or Security Document falls on a day which is not a Business Day, the
due date for such payment (subject to the definition of Interest
Period) shall be extended to the next succeeding Business Day and
interest shall be payable for any principal so extended for the period
of such extension.

     5.2. PRO RATA TREATMENT.  Except to the extent otherwise provided
herein, (a) each borrowing from the Banks hereunder, each payment of
Commitment Fees and other fees and each termination or reduction of
the Commitments of the Banks under SECTION 2.3 shall be made PRO RATA
according to the Banks' respective Commitments, and (b) each payment
by the Company of principal of or interest on Loans of a particular
Type shall be made to the Agent for the account of the Banks PRO RATA
in accordance with the respective unpaid principal amounts of such
Loans held by the Banks (subject to SECTION 6.4).

     5.3. COMPUTATIONS.  Interest based on the Alternate Base Rate (to
the extent determined by reference to the Prime Rate), and fees
hereunder, will be computed on the basis of 365 (or 366) days and
actual days elapsed (including the first day but excluding the last
day) occurring in the period for which payable.  All other interest
shall be computed on the basis of a year of 360 days and actual days
elapsed (including the first day but excluding the last day) occurring
in the period for which payable, unless the effect of so computing
shall be to cause the rate of interest to exceed the Highest Lawful
Rate (in which event interest shall be calculated on the basis of the
actual number of days elapsed in a year composed of 365 or 366 days,
as the case may be).

     5.4. MINIMUM AND MAXIMUM AMOUNTS.  Except for prepayments made
pursuant to SECTION 3.2(b), each borrowing and repayment of principal
of Loans, each optional prepayment and each conversion of Type shall
be in an aggregate principal amount equal to $1,000,000, or an
integral multiple thereof (borrowings or prepayments of Loans of
different Types or, in the case of Eurodollar Loans, having different
Interest Periods at the same time hereunder, to be deemed separate
borrowings and prepayments for purposes of the foregoing, one for each
Type or Interest Period), and each termination or reduction of
Commitments shall be in an aggregate principal amount equal to
$5,000,000 or an integral multiple thereof.  Upon any mandatory
prepayment that would reduce Eurodollar Loans having the same Interest
Period to less than $1,000,000, such Loans shall automatically be
converted into Alternate Base Rate Loans.

     5.5. CERTAIN ACTIONS, NOTICES, ETC.  Notices to the Agent of any
termination or reduction of Commitments, prepayments of Loans and of
the duration of Interest Periods and Requests for Extension 

                                 -55-
<PAGE>

of Credit shall be irrevocable and shall be effective only if received
by the Agent not later than 11:00 a.m. on the number of Business Days
prior to the date of the relevant termination, reduction, borrowing
and/or prepayment specified below:

                                        Number of Business
                                             Days Prior   
                                               Notice     

     Termination or reduction
     of Commitments                          10

     Borrowing or prepayment
     of or conversion into
     Alternate Base Rate Loans              same day

     Borrowing or prepayment
     of or conversion into or
     continuance of Eurodollar
     Loans                                    3

     Prepayments required
     pursuant to SECTION 3.2                  1

Each such notice of termination or reduction shall specify the amount
of the Commitment to be terminated or reduced.  Each such notice of
prepayment or Request for Extension of Credit shall specify the
amount, Class and Type of the Loans to be borrowed or prepaid (subject
to SECTIONS 3.2(a) and 5.4), the date of borrowing or prepayment
(which shall be a Business Day) and, in the case of Eurodollar Loans,
the duration of the Interest Period therefor (subject to the
definition of Interest Period).  Any such notice of conversion of a
Loan into a Loan of another Type shall identify such Loan (or portion
thereof) being converted and specify the Type of Loan into which such
Loan is being converted (subject to SECTION 5.4) and the date for
conversion (which shall be a Business Day) and, unless such Loan is
being converted into an Alternate Base Rate Loan, the duration
(subject to the definition of Interest Period) of the Interest Period
therefor which is to commence as of the last day of the then current
Interest Period therefor (or the date of conversion, if such Loan is
being converted from an Alternate Base Rate Loan).  Each such notice
of continuation of a Loan (or portion thereof) as the same Type of
Loan shall identify such Loan (or portion thereof) being continued
(subject to SECTION 5.4) and the duration (subject to the definition
of Interest Period) of the Interest Period therefor which is to
commence as of the last day of the then current Interest Period
therefor.  The Agent shall promptly notify the Banks of the contents
of each such notice or Request for Extension of Credit.  

                                 -56-
<PAGE>

Notice of any prepayment having been given, the principal amount
specified in such notice, together with interest thereon to the date
of prepayment, shall be due and payable on such prepayment date.

     5.6. NON-RECEIPT OF FUNDS BY THE AGENT.  Unless the Agent shall
have been notified by a Bank prior to noon on the date on which such
Bank is to make payment to the Agent of the proceeds of a Loan to be
made by it hereunder or by the Company prior to the date on which the
Company is to make a payment to the Agent for the account of one or
more of the Banks, as the case may be (such Bank or the Company being
herein called the "PAYOR" and such payment being herein called the
"REQUIRED PAYMENT"), which notice shall be effective upon receipt,
that the Payor does not intend to make the Required Payment to the
Agent, the Agent may assume that the Required Payment has been made
and may, in reliance upon such assumption (but shall not be required
to), make the amount thereof available to the intended recipient on
the date that such Required Payment is to be made.  If the Payor is
the Company and the Company has not in fact made the Required Payment
to the Agent on or before such date, the recipient of such payment
shall, on demand, pay to the Agent the amount made available by the
Agent, together with interest thereon from the date such amount was so
made available by the Agent until the date the Agent recovers such
amount at a rate per annum equal to the Fed Funds Rate for the first
three days after demand and thereafter at the Fed Funds Rate plus 2%. 
If the Payor is a Bank and such Bank has not in fact made the Required
Payment to the Agent on or before such date, then such Bank shall pay
to the Agent the amount made available by the Agent on behalf of such
Bank, together with interest thereon from the date such amount was so
made available by the Agent until the Agent recovers such amount at a
rate per annum equal to the Fed Funds Rate for the first three days
and thereafter at the Fed Funds Rate plus 2%.

     5.7. SHARING OF PAYMENTS, ETC.  If a Bank or any participant of a
Bank shall obtain payment of any obligation to it under this
Agreement, through the exercise of any right of set-off, banker's
lien, counterclaim or similar right, or otherwise, then such Bank or
participant shall promptly purchase from the other Banks participa-
tions in the Loans made or other obligations held by the other Banks
in such amounts, and make such other adjustments from time to time as
shall be equitable to the end that all the Banks and participants
shall share the benefit of such payment (net of any expenses which may
be incurred by such Bank or its participant in obtaining or preserving
such benefit) PRO RATA in accordance with the unpaid principal and
interest then due to each of them.  To such end all the Banks and
their participants shall make appropriate adjustments among themselves
(by the resale of participations sold or otherwise) if such payment is
rescinded or 

                                 -57-
<PAGE>

must otherwise be restored.  The Company agrees, to the fullest extent
it may effectively do so under applicable law, that any Person so
purchasing a participation in the Loans made or other obligations held
by other Banks may exercise all rights of set-off, bankers' lien,
counterclaim or similar rights with respect to such participation as
fully as if such Bank were a direct holder of Loans or other
obligations in the amount of such participation.  Nothing contained
herein shall require any Bank to exercise any such right or shall
affect the right of any Bank to exercise, and retain the benefits of
exercising, any such right with respect to any other indebtedness or
obligation of the Company.

     Section 6.  YIELD PROTECTION AND ILLEGALITY.  

     6.1. ADDITIONAL COSTS.

     (a)  Subject to SECTION 12.8, the Company shall pay to the Agent,
on demand for the account of such Bank, from time to time such amounts
as any Bank may reasonably determine to be necessary to compensate it
for any costs incurred by such Bank which such Bank reasonably
determines are attributable to its making or maintaining of any
Eurodollar Loan hereunder or its obligation to make or maintain any
such Loan hereunder, or any reduction in any amount receivable by such
Bank hereunder in respect of any of such Loans or such obligation
(such increases in costs and reductions in amounts receivable being
herein called "ADDITIONAL COSTS"), in each case resulting from any
Regulatory Change which:

          (1)  subjects such Bank (or makes it apparent that such Bank
is subject) to any tax (including any United States interest equali-
zation tax), levy, impost, duty, charge or fee (collectively,
"TAXES"), or any deduction or withholding for any Taxes on or from the
payment due under any Eurodollar Loan or other amounts due hereunder,
other than income and franchise taxes of the jurisdiction (or any
subdivision thereof) in which such Bank has an office or its
Applicable Lending Office; or

          (2)  changes the basis of taxation of any amounts payable to
such Bank under this Agreement or its Notes in respect of any of such
Loans, other than changes which affect taxes measured by or imposed on
the overall net income or franchise taxes of such Bank or of its
Applicable Lending Office for any of such Loans by the jurisdiction
(or any subdivision thereof) in which such Bank has an office or such
Applicable Lending Office; or

          (3)  imposes or modifies or increases or deems applicable
any reserve, special deposit or similar requirement (including any
such requirement imposed by the Board) relating to any extensions of
credit or other assets of, or any deposits with or other 

                                 -58-
<PAGE>

liabilities of, such Bank or loans made by such Bank, or against any
other funds, obligations or other property owned or held by such Bank; or

          (4)  imposes any other condition affecting this Agreement
(or any of such extensions of credit or liabilities).

Each Bank will notify the Company through the Agent of any event
occurring after the date of this Agreement which will entitle such
Bank to compensation pursuant to this section as promptly as
practicable after it obtains knowledge thereof and determines to
request such compensation, and (if so requested by the Company through
the Agent) will designate a different available Applicable Lending
Office for the Eurodollar Loans of such Bank or take such other action
as the Company may reasonably request if such designation or action is
consistent with the internal policy of such Bank and legal and
regulatory restrictions, can be undertaken at no additional cost, will
avoid the need for, or reduce the amount of, such compensation and
will not, in the sole opinion of such Bank, be disadvantageous to such
Bank (PROVIDED that such Bank shall have no obligation so to designate
an Applicable Lending Office located in the United States of America). 
Each Bank will furnish the Company with a statement setting forth the
basis and amount of each request by such Bank for compensation under
this section, with each such statement to cover amounts accruing under
this section with respect to a period beginning not earlier than 120
days from the date thereof and using any reasonable averaging and
attribution methods.

     (b)  Without limiting the effect of the foregoing provisions of
this section, in the event that, by reason of any Regulatory Change,
any Bank either (1) incurs Additional Costs based on or measured by
the excess above a specified level of the amount of a category of
deposits or other liabilities of such Bank which includes deposits by
reference to which the interest rate on Eurodollar Loans is determined
as provided in this Agreement or a category of extensions of credit or
other assets of such Bank which includes Eurodollar Loans or (2)
becomes subject to restrictions on the amount of such a category of
liabilities or assets which it may hold, then, if such Bank so elects
by notice to the Company (with a copy to the Agent), the obligation of
such Bank to make Eurodollar Loans hereunder shall be suspended until
the date such Regulatory Change ceases to be in effect (in which case
the provisions of SECTION 6.4 shall be applicable).

     (c)  Determinations and allocations by any Bank for purposes of
this section of the effect of any Regulatory Change on its costs of
maintaining its obligations to make Loans or of making or maintaining
Loans or on amounts receivable by it in respect of 

                                 -59-
<PAGE>

Loans, and of the additional amounts required to compensate such Bank
in respect of any Additional Costs, shall be conclusive, absent
manifest error, and may be prepared using any reasonable averaging and
attribution methods.

     (d)  In the event any Bank shall seek compensation pursuant to
this SECTION 6.1, the Company may give notice to such Bank (with
copies to the Agent) that it wishes to seek one or more Eligible
Assignees (which may be one or more of the Banks) to purchase and
assume the Commitments, Loans, Notes and Letter of Credit Liabilities
of such Bank.  Each Bank requesting compensation pursuant to this
SECTION 6.1 agrees to sell its Commitments, Loans, Notes, Letter of
Credit Liabilities and interests in this Agreement and in the Letter
of Credit Agreement pursuant to SECTION 12.6 (without recourse,
representation or warranty except as provided in SECTION 12.6) to any
such Eligible Assignee for an amount equal to the sum of the
outstanding unpaid principal of and accrued interest on such Loans,
Notes and Letter of Credit Liabilities plus all other fees and amounts
(including any compensation claimed by such Bank under this
SECTION 6.1) owing to such Bank hereunder and under the Letter of
Credit Agreement calculated, in each case, to the date such
Commitments, Loans, Notes, Letter of Credit Liabilities and interests
are purchased, whereupon such Bank shall have no further Commitment or
other obligation to the Company hereunder or under any Note or under
the Letter of Credit Agreement.

     6.2. LIMITATION ON TYPES OF LOANS.  Anything herein to the
contrary notwithstanding, if, with respect to any Eurodollar Loans:

     (a)  the Agent determines (which determination shall be
conclusive absent manifest error) that quotations of interest rates
for the relevant deposits referred to in the definition of "Eurodollar
Base Rate" in SECTION 1.1 are not being provided in the relevant
amounts or for the relevant maturities for purposes of determining the
rate of interest for such Loans for Interest Periods therefor as
provided in this Agreement; or

     (b)  the Required Banks determine (which determination shall be
conclusive absent manifest error) and notify the Agent that the
relevant rates of interest referred to in the definition of "Eurodol-
lar Base Rate" in SECTION 1.1 upon the basis of which the rates of
interest for such Loans are to be determined do not accurately reflect
the cost to such Banks of making or maintaining such Loans for any
proposed Interest Periods therefor; or

     (c)  the Agent determines (which determination shall be
conclusive absent manifest error) that by reason of circumstances
affecting the Eurodollar interbank market generally, deposits in
dollars in the relevant Eurodollar interbank market are not being 

                                 -60-

offered for the applicable Interest Period and in an amount equal to
the amount of the Eurodollar Loan requested by the Company;

then the Agent shall promptly notify the Company and each Bank
thereof, and, so long as such condition remains in effect, the Banks
shall be under no obligation to make Eurodollar Loans (but shall
maintain until the end of the Interest Period then in effect the
Eurodollar Loans then outstanding).

     6.3. ILLEGALITY.  Notwithstanding any other provision of this
Agreement to the contrary, if by reason of (x) the adoption of any
applicable Legal Requirement or any change in any applicable Legal
Requirement or in the interpretation or administration thereof by any
Governmental Authority or compliance by any Bank with any request or
directive (whether or not having the force of law) of any central bank
or other Governmental Authority or (y) circumstances affecting the
relevant Eurodollar interbank market or the position of a Bank
therein, it shall at any time be unlawful or impracticable in the sole
discretion of a Bank for such Bank or its Applicable Lending Office to
(a) honor its obligation to permit the establishment of Eurodollar
Loans hereunder or (b) maintain Eurodollar Loans hereunder, then such
Bank through the Agent shall promptly notify the Company thereof and
the obligation of such Bank to establish or maintain Eurodollar Loans
hereunder shall be suspended until such time as such Bank may again
establish and maintain Eurodollar Loans, in which case the provisions
of SECTION 6.4 shall be applicable.  Before giving such notice
pursuant to this section, such Bank will designate a different
available Applicable Lending Office for the Eurodollar Loans of such
Bank or take such other action as the Company may reasonably request
if such designation or action is consistent with the internal policy
of such Bank and legal and regulatory restrictions, can be undertaken
at no additional cost, will avoid the need to suspend such Bank's
obligation to make Eurodollar Loans hereunder and will not, in the
sole opinion of such Bank, be disadvantageous to such Bank (PROVIDED
that such Bank shall have no obligation so to designate an Applicable
Lending Office located in the United States of America).  In the event
any Bank shall seek to invoke the benefits of this section, the
Company may give notice to such Bank (with copies to the Agent) that
it wishes to seek one or more Eligible Assignees (which may be one or
more of the Banks) to purchase and assume the Commitments, Loans,
Notes and Letter of Credit Liabilities of such Bank.  Each Bank
requesting to invoke the benefits of this SECTION 6.3 agrees to sell
its Commitments, Loans, Notes, Letter of Credit Liabilities and
interests in this Agreement and in the Letter of Credit Agreement
pursuant to SECTION 12.6 (without recourse, representation or warranty
except as provided in SECTION 12.6) to any such Eligible Assignee for
an amount equal to the sum of the outstanding unpaid principal of and

                                 -61-
<PAGE>

accrued interest on such Loans, Notes and Letter of Credit Liabilities
plus all other fees and amounts owing to such Bank hereunder and under
the Letter of Credit Agreement calculated, in each case, to the date
such Commitments, Loans, Notes, Letter of Credit Liabilities and
interests are purchased, whereupon such Bank shall have no further
Commitment or other obligation to the Company hereunder or under any
Note or under the Letter of Credit Agreement.

     6.4. SUBSTITUTE ALTERNATE BASE RATE LOANS.  If the obligation of
any Bank to make or maintain Eurodollar Loans shall be suspended
pursuant to SECTION 6.1, 6.2 or 6.3, all Loans which would otherwise
be made by such Bank as Eurodollar Loans shall be made instead as
Alternate Base Rate Loans (and, if an event referred to in
SECTION 6.1(b) or 6.3 has occurred and such Bank so requests by notice
to the Company with a copy to the Agent, each Eurodollar Loan of such
Bank then outstanding shall be automatically converted into an
Alternate Base Rate Loan on the date specified by such Bank in such
notice) and, to the extent that such Loans are so made as (or
converted into) Alternate Base Rate Loans, all payments of principal
which would otherwise be applied to such Loans shall be applied
instead to such Alternate Base Rate Loans.

     6.5. COMPENSATION.  Subject to SECTION 12.8, the Company shall
pay to the Agent for the account of each Bank, within two Business
Days after demand therefor by such Bank through the Agent, such amount
or amounts as shall be sufficient (in the reasonable opinion of such
Bank) to compensate it for any loss, cost or expense incurred by it as
a result of:

     (a)  any payment, prepayment or conversion of a Eurodollar Loan
made by such Bank on a date other than the last day of an Interest
Period for such Loan; or

     (b)  any failure by the Company to borrow a Eurodollar Loan to be
made by such Bank on the date for such borrowing specified in the
relevant notice of borrowing under SECTION 5.5 or to convert an 
Alternate Base Rate Loan into a Eurodollar Loan on such date after
giving notice of such conversion or to continue a Eurodollar Loan
after giving notice of such continuance; or

     (c)  any cessation of the Eurodollar Rate to apply to any Loan or
any part thereof;

such compensation to include, without limitation, an amount equal to
the excess, if any, as reasonably determined by each Bank, of (1) its
cost of obtaining the funds for the Loan being paid, prepaid or
converted or not borrowed, converted or continued (assumed to be the
applicable Eurodollar Base Rate) for the period 

                                 -62-
<PAGE>
from the date of such payment, prepayment or conversion or failure to
borrow convert or continue to the last day of the Interest Period for
such Loan (or, in the case of a failure to borrow, convert or continue
the Interest Period for the Loan which would have commenced on the
date of such failure to borrow convert or continue) over (2) the
amount of interest (as reasonably determined by such Bank) that would
be realized by such Bank in reemploying the funds so paid, prepaid or
converted or not borrowed, converted or continued for such period or
Interest Period, as the case may be.  Each determination of the amount
of such compensation by a Bank shall be conclusive and binding, absent
manifest error, and may be computed using any reasonable averaging and
attribution method.

     6.6. CAPITAL ADEQUACY.  If any Bank shall have determined that
the adoption after the date hereof or effectiveness after the date
hereof (regardless of whether previously announced) of any applicable
Legal Requirement or treaty regarding capital adequacy, or any change
after the date hereof in any existing or future Legal Requirement or
treaty regarding capital adequacy, or any change in the interpretation
or administration thereof after the date hereof by any Governmental
Authority or comparable agency charged with the interpretation or
administration thereof, or compliance by any Bank (or its Applicable
Lending Office) with any request or directive after the date hereof
regarding capital adequacy (whether or not having the force of law) of
any such Governmental Authority or comparable agency has or would have
the effect of reducing the rate of return on the capital of such Bank
(or any holding company of which such Bank is a part) as a consequence
of its obligations hereunder and under or in respect of the Notes held
by it to a level below that which such Bank or holding company could
have achieved but for such adoption, change or compliance by an amount
deemed by such Bank to be material, then from time to time, upon
demand by such Bank (with a copy to the Agent), the Company (subject
to SECTION 12.8) shall pay to such Bank such additional amount or
amounts as will compensate such Bank or holding company for such
reduction.  The certificate of any Bank setting forth such amount or
amounts as shall be necessary to compensate it and the basis therefor
shall cover amounts accruing under this section with respect to a
period beginning not earlier than 120 days from the date thereof and
shall be conclusive and binding, absent manifest error.  The Company
shall pay the amount shown as due on any such certificate upon
delivery of such certificate.  In preparing such certificate, a Bank
may employ such assumptions and allocations of costs and expenses as
it shall in good faith deem reasonable and may use any reasonable
averaging and attribution method.  In the event any Bank shall seek
compensation pursuant to this section, the Company may give notice to
such Bank (with copies to the Agent) that it wishes to seek one or
more Eligible Assignees (which may be 

                                 -63-
<PAGE>

one or more of the Banks) to purchase and assume the Commitments,
Loans, Notes and Letter of Credit Liabilities of such Bank.  Each Bank
requesting compensation pursuant to this section agrees to sell its
Commitments, Loans, Notes, Letter of Credit Liabilities and interests
in this Agreement and in the Letter of Credit Agreement pursuant to
SECTION 12.6 (without recourse, representation or warranty except as
provided in SECTION 12.6) to any such Eligible Assignee for an amount
equal to the sum of the outstanding unpaid principal of and accrued
interest on such Loans, Notes and Letter of Credit Liabilities plus
all other fees and amounts (including any compensation claimed by such
Bank under this section owing to such Bank hereunder and under the
Letter of Credit Agreement calculated, in each case, to the date such
Commitments, Loans, Notes, Letter of Credit Liabilities and interests
are purchased, whereupon such Bank shall have no further Commitment or
other obligation to the Company hereunder or under any Note or the
Letter of Credit Agreement.

the additional conditions precedent that, as of the date of such Loan,
and after giving effect thereto:  

     (a)  no Default shall have occurred and be continuing (PROVIDED,

warranties made in each Credit Document shall be true and correct in

shall include a representation and warranty by the Company to the
effect set forth in SUBSECTIONS (a) through (e) (if applicable) of
this SECTION 7.2 (both as of the date of such notice and, unless the
Company otherwise notifies the Agent prior to the date of such
borrowing, as of the date of such borrowing).  Except in the case of
Loans on the date hereof, such representation and warranty shall be
accompanied by a certificate of the President or chief financial
officer of the Company setting forth in reasonable detail the

business, and is in good standing, in (1) all jurisdictions in which
any of the Recognized Proved Reserves which it owns are located and
(2) any other jurisdiction in which the nature of the business
conducted by it makes such qualification necessary or advisable,
unless (for purposes only of this CLAUSE (2)) the failure to be so
qualified or in good standing would not individually or in the
aggregate have a material adverse effect on the business, financial
condition or results of operations of the Combined Group taken as a
whole.

     8.2. INFORMATION.

     (a)  (1)  The most recent consolidated balance sheet of the
Company and its Subsidiaries and the related consolidated statements

Legal Requirement (including any securities law, rule or regulation)
applicable to the Company or any of its Subsidiaries or (except for
the Liens required or permitted by this Agreement and the Security
Documents) result in the creation or imposition of any Lien upon any
of the revenues or property of the Company or any of its Subsidiaries. 
Such execution, delivery, consummation and compliance do not and will

the Agent prior to the date hereof, the Company and its Subsidiaries,
and the plants and sites of each, have complied with all Applicable
Environmental Laws, except, in any such case, where such failure to so

limiting the generality of the preceding sentence, neither the Company
nor any of its Subsidiaries has received notice of or has actual
knowledge of any actual or claimed or asserted failure so to comply
with Applicable Environmental Laws or of any other Environmental Claim
which alone or together with all other such failures or Environmental
Claims is material and would result in a Material Adverse Change. 
Except as disclosed in writing to the Agent prior to the date hereof,
neither the Company nor any of its Subsidiaries nor their plants or

Environmental Laws or any other applicable Legal Requirement, or in a
manner which would result in an Environmental Claim except where such
noncompliance or liability or Environmental Claim would not result in
a Material Adverse Change.  The representation and warranty contained
in this section is based in its entirety upon (a) current

sites in a particular jurisdiction and (b) current levels of publicly
disseminated scientific knowledge concerning the detection of, and the
health and environmental risks associated with the discharge of,
substances and pollutants regulated pursuant to the Applicable

     (c)  The Company has full right, power and authority to execute,
deliver and perform the Security Documents with respect to all such
properties and to convey, assign and mortgage the same, without the
necessity of any consent, approval or other action of any kind of or
by any other Person, failure to obtain which could cause a Material
Adverse Change, and such execution, delivery and performance will not
result in the breach of or constitute a default under any agreement,
instrument, judgment, license, order or permit to which the Company is
a party or by which the Company  or any of its property may be bound,
which together with all other such breaches and defaults could cause a
Material Adverse Change. 

     (d)  All oil, gas and mineral leases and leasehold estates, gas
purchase and sales contracts, and other agreements comprising or
relating to any of such properties are valid and subsisting and in
full force and effect, except for those leases, estates, contracts,

material to oil, gas and mineral properties included in the Adobe
Properties in the Most Recent Engineering Report furnished to the
Banks, taken as a whole.

     (e)  All rights, permits, easements, servitudes and
rights-of-way, failure to have or maintain which would materially
interfere with the development, maintenance and operation of such
properties so as to cause a Material Adverse Change, have been
obtained by the Company and are in full force and effect.

     (f)  Each of the Security Documents creates or will create, when
executed and delivered, a valid Lien upon the Property therein
described.

     Section 9.  COVENANTS.  The Company agrees with the Banks and the

which expressly assumes in writing the due and punctual performance of
the obligations of the Company under the Credit Documents, to the same
extent as if such successor or transferee corporation had originally
executed the Credit Documents in the place of the Company (it being
agreed that such assumption shall, upon the request of any Bank and at

and form 

                                 -88-

shall give written notice thereof to each Bank describing in
reasonable detail the proposed transaction, the date on which it is
proposed to be consummated and the identity, jurisdiction of
organization, and geographic composition of assets of the proposed
successor or transferee corporation.  No disposition by the Company of

amount of such net sales proceeds; or

          (3)  the Sale and Leaseback Transaction involves the sale of
assets by the Company to a wholly owned Restricted Subsidiary or by a
Restricted Subsidiary to the Company or to another wholly owned
Restricted Subsidiary; PROVIDED that if the Company is the seller
under any such Sale and Leaseback Transaction, its lease obligations
thereunder shall be subordinated to the Funded Debt represented by the

compensation in connection therewith and (B) subject to applicable
fiduciary standards with respect to the Special Subsidiary, acts and
transactions that would otherwise be prohibited by this Subsection may
be performed or engaged in if upon terms not less favorable to the
Company or any Restricted Subsidiary than if no relationship described

     (i)  TAX CONSOLIDATION.  Except for the Tax Allocation
Agreements, the Company will not, and will not permit any of its
Subsidiaries to, file or consent to the filing of any consolidated
income tax return with any Person unless such other Person shall have
agreed in writing with the Company that the Company's or such
Subsidiary's liability with respect to taxes as a result of the filing
of any such consolidated income tax return with such Person 

                                 -90-

Subsidiary.

permitted by SECTION 10.1(e)).

Company or any ERISA Affiliate; PROVIDED, however, any amounts owing
by Santa Fe Pacific Corporation pursuant to the ERISA Indemnification
Agreement between Santa Fe Pacific Corporation and the Company shall
first be offset against the dollar threshold amounts set forth above
before any such condition or event constitutes an event of default
under this paragraph; or

     (q)  one or more demands for payment is made upon the Company by

the aggregate; or 

     (r)  any Change of Control shall occur; or

     (s)  any Event of Default shall occur and be continuing under the
Letter of Credit Agreement,

THEREUPON:  (I) the Agent may (and, if directed by the Required Banks,
shall) do any or all of the following: (a) declare the Commitments
terminated (whereupon the Commitments shall be terminated); and (b)
declare the principal amount then outstanding of and the accrued
interest on the Loans and all fees and all other amounts payable
hereunder and under the Notes to be forthwith due and payable, where-
upon such amounts shall be and become immediately due and payable,
without notice (including notice of acceleration and notice of intent
to accelerate), presentment, demand, protest or other formalities of
any kind, all of which are hereby expressly WAIVED by the Company;
PROVIDED that in the case of the occurrence of an Event of Default
with respect to the Company referred to in SECTION 10.1(g) through
(l), the Commitments shall be automatically terminated and the prin-
cipal amount then outstanding of and the accrued interest on the Loans
and fees and all other amounts payable hereunder and under the Notes
shall be and become automatically and immediately due and payable,
without notice (including notice of intent to accelerate and notice of
acceleration) and without presentment, demand, protest or other for-
malities of any kind, all of which are hereby expressly WAIVED by the
Company; (II) each Bank may exercise its rights of offset against each
account and all other property of the Company in the possession of
such Bank, which right is hereby granted by the Company to the Banks; 
                                 -95-

and (III) the Agent and each Bank may exercise any and all other
rights pursuant to the Credit Documents, at law and in equity. 

     Section 11.  THE AGENT.

     11.1.     APPOINTMENT, POWERS AND IMMUNITIES.  Each Bank hereby
irrevocably appoints and authorizes the Agent to act as its Agent
under the Credit Documents with such powers as are specifically
delegated to the Agent by the terms thereof, together with such other
powers as are reasonably incidental thereto, including the execution
and delivery of the First Amendment to Deed of Trust.  The Agent
(which term as used in this section shall include reference to its
Affiliates and its own and its Affiliates' officers, directors,
employees and agents) shall (a) have no duties or responsibilities
except those expressly set forth in the Credit Documents, and shall
not by reason of any Credit Document be a trustee or fiduciary for any
Bank; (b) not be responsible to any Bank for any recitals, statements,
representations or warranties contained in any Credit Document, or in
any certificate or other document referred to or provided for in, or
received by any of them under, any Credit Document, or for the value,
validity, effectiveness, genuineness, enforceability or sufficiency of
any Credit Document or any other document referred to or provided for
therein or any property covered thereby or for any failure by the
Company or any other Person to perform any of its obligations
thereunder; (c) not be required to initiate or conduct any litigation
or collection proceedings hereunder or under any Credit Document
except to the extent requested by the Required Banks (and SECTION 11.7
shall apply), and (d) not be responsible for any action taken or
omitted to be taken by it under any Credit Document or any other
document or instrument referred to or provided for therein or in
connection therewith, including pursuant to its own negligence, except
for its own gross negligence or willful misconduct.  The Agent may
employ agents and attorneys-in-fact and shall not be responsible for
the negligence or misconduct of any such agents or attorneys-in-fact
selected by it with reasonable care.  In any foreclosure proceeding
concerning any collateral for the Notes or other obligations of the
Company hereunder, each holder of a Note or other obligations of the
Company hereunder if bidding for its own account or for its own
account and the accounts of other Banks is prohibited from including
in the amount of its bid an amount to be applied as a credit against
its Notes or the Notes of the other Banks; instead, such holder must
bid in cash only.  

     11.2.     RELIANCE BY AGENT.  The Agent shall be entitled to rely
upon any certification, notice or other communication (including any
thereof by telephone, telex, telegram or cable) believed by it to be
genuine and correct and to have been signed or sent by or on behalf of
the proper Person or Persons, and upon 

                                 -96-
<PAGE>

advice and statements of legal counsel (which may be counsel for the
Company), independent accountants and other experts selected by the
Agent.  As to any matters not expressly provided for by any Credit
Document, the Agent shall in all cases be fully protected in acting,
or in refraining from acting, hereunder and thereunder in accordance
with instructions of the Required Banks, and any action taken or
failure to act pursuant thereto shall be binding on all of the Banks. 
Pursuant to instructions of all Banks or the Required Banks, as
appropriate, the Agent shall have the authority to execute releases of
the Security Documents on behalf of the Banks without the joinder of
any Bank.

     11.3.     DEFAULTS.  The Agent shall not be deemed to have know-
ledge of the occurrence of a Default (other than the non-payment of
principal of or interest on Loans) unless it has received notice from
a Bank or the Company specifying such Default and stating that such
notice is a "Notice of Default".  In the event that the Agent receives
such a notice of the occurrence of a Default, the Agent shall give
prompt notice thereof to the Banks (and shall give each Bank prompt
notice of each such non-payment).  The Agent shall (subject to
SECTIONS 11.7 and 12.5) take such action with respect to such Default
as shall be directed by all Banks or the Required Banks, as
appropriate, and within its rights under the Credit Documents and at
law or in equity; PROVIDED that, unless and until the Agent shall have
received such directions, the Agent may (but shall not be obligated
to) take such action, or refrain from taking such action, permitted
hereby with respect to such Default as it shall deem advisable in the
best interests of the Banks and within its rights under the Credit
Documents, at law or in equity.

     11.4.     RIGHTS AS A BANK.  With respect to their Commitments
and Loans, TCB and NationsBank in their capacities as Banks hereunder
shall have the same rights and powers hereunder as any other Bank and
may exercise the same as though they were not acting as the Agent or
the Co-Agents, and the term "Bank" or "Banks" shall, unless the
context otherwise indicates, include the Agent and the Co-Agents in
their individual capacity.  The Agent and the Co-Agents may (without
having to account therefor to any Bank) accept deposits from, lend
money to and generally engage in any kind of banking, trust, letter of
credit, agency or other business with the Company (and any of its
Affiliates) as if they were not acting as the Agent and the Co-Agents,
and the Agent and the Co-Agents may accept fees and other considera-
tion from the Company and its Affiliates (in addition to the fees
heretofore agreed to between the Company and the Agent or the
Co-Agents) for services in connection with this Agreement or otherwise
without having to account for the same to the Banks.

                                 -97-
<PAGE>

     11.5.     INDEMNIFICATION.  THE BANKS AGREE TO INDEMNIFY THE
AGENT (TO THE EXTENT NOT REIMBURSED UNDER SECTION 12.3 OR 12.4, BUT
WITHOUT LIMITING THE OBLIGATIONS OF THE COMPANY UNDER SAID
SECTIONS 12.3 AND 12.4), RATABLY IN ACCORDANCE WITH THEIR RESPECTIVE
COMMITMENTS, FOR ANY AND ALL LIABILITIES, OBLIGATIONS, LOSSES,
DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES OR
DISBURSEMENTS OF ANY KIND AND NATURE WHATSOEVER (INCLUDING THE
CONSEQUENCES OF THE NEGLIGENCE OF THE AGENT) WHICH MAY BE IMPOSED ON,
INCURRED BY OR ASSERTED AGAINST THE AGENT IN ANY WAY RELATING TO OR
ARISING OUT OF ANY CREDIT DOCUMENT (AS DEFINED HEREIN) OR ANY OTHER
DOCUMENTS CONTEMPLATED BY OR REFERRED TO THEREIN OR THE TRANSACTIONS
CONTEMPLATED THEREBY (INCLUDING THE COSTS AND EXPENSES WHICH THE
COMPANY IS OBLIGATED TO PAY UNDER SECTIONS 12.3 AND 12.4 BUT
EXCLUDING, UNLESS A DEFAULT HAS OCCURRED AND IS CONTINUING, NORMAL
ADMINISTRATIVE COSTS AND EXPENSES INCIDENT TO THE PERFORMANCE OF ITS
AGENCY DUTIES HEREUNDER) OR THE ENFORCEMENT OF ANY OF THE TERMS HEREOF
OR THEREOF OR OF ANY SUCH OTHER DOCUMENTS, INCLUDING THE NEGLIGENCE OF
THE AGENT; PROVIDED THAT NO BANK SHALL BE LIABLE FOR ANY OF THE
FOREGOING TO THE EXTENT THEY ARISE FROM THE GROSS NEGLIGENCE OR
WILLFUL MISCONDUCT OF THE PARTY TO BE INDEMNIFIED.  The obligations of
the Banks under this SECTION 11.5 shall survive the termination of
this Agreement.

     11.6.     NON-RELIANCE ON THE AGENT AND OTHER BANKS.  Each Bank
agrees that it has received current financial information with respect
to the Company and that it has, independently and without reliance on
the Agent, the Co-Agents or any other Bank and based on such documents
and information as it has deemed appropriate, made its own credit
analysis of the Company and decision to enter into this Agreement and
that it will, independently and without reliance upon the Agent, the
Co-Agents or any other Bank, and based on such documents and
information as it shall deem appropriate at the time, continue to make
its own analysis and decisions in taking or not taking action under
the Credit Documents.  The Agent and the Co-Agents shall not be
required to keep themselves informed as to the performance or
observance by the Company of any Credit Document or any other document
referred to or provided for therein or to inspect the property or
books of the Company or any other Person.  Except for notices, reports
and other documents and information expressly required to be furnished
to the Banks by the Agent and the Co-Agents under the Credit
Documents, the Agent and the Co-Agents shall not have any duty or
responsibility to provide any Bank with any credit or other
information concerning the affairs, financial condition or business of
the Company (or any of its Affiliates) which may come into the
possession of the Agent or either Co-Agent.

     11.7.     FAILURE TO ACT.  Except for action expressly required
of the Agent under the Credit Documents, the Agent shall 

                                 -98-
<PAGE>

in all cases be fully justified in failing or refusing to act
hereunder and thereunder unless it shall receive further assurances to
its satisfaction by the Banks of their indemnification obligations
under SECTION 11.5 against any and all liability and expense which may
be incurred by it by reason of taking or continuing to take any such
action.

     11.8.     RESIGNATION OR REMOVAL OF THE AGENT.  Subject to the
appointment and acceptance of a successor Agent as provided below, the
Agent may resign at any time by giving notice thereof to the Banks and
the Company, and the Agent may be removed at any time with or without
cause by the Required Banks.  Upon any such resignation or removal,
the Required Banks shall have the right to appoint a successor Agent. 
If no successor Agent shall have been so appointed by the Required
Banks and shall have accepted such appointment within 30 days after
the retiring Agent's giving of notice of resignation or the Required
Banks' removal of the retiring Agent, then the retiring Agent may, on
behalf of the Banks, appoint a successor Agent.  Any successor Agent
shall be a bank which has an office in the United States and a
combined capital and surplus of at least $250,000,000 and with its
deposits insured by the FDIC.  Upon the acceptance of any appointment
as the Agent hereunder by a successor Agent, such successor Agent
shall thereupon succeed to and become vested with all the rights,
powers, privileges and duties of the retiring Agent, and the retiring
Agent shall be discharged from its duties and obligations hereunder. 
Such successor Agent shall promptly specify its Principal Office
referred to in SECTIONS 3.1 and 5.1 by notice to the Company.  After
any retiring Agent's resignation or removal hereunder as the Agent,
the provisions of this SECTION 11 shall continue in effect for its
benefit in respect of any actions taken or omitted to be taken by it
while it was acting as the Agent.

     Section 12.  MISCELLANEOUS.

     12.1.     WAIVER.  No waiver of any Default shall be a waiver of
any other Default.  No failure on the part of the Agent or any Bank to
exercise and no delay in exercising, and no course of dealing with
respect to, any right, power or privilege under any Credit Document
shall operate as a waiver thereof, nor shall any single or partial
exercise of any right, power or privilege thereunder preclude any
other or further exercise thereof or the exercise of any other right,
power or privilege.  The remedies provided in the Credit Documents are
cumulative and not exclusive of any remedies provided by law or in
equity.

    12.2. NOTICES.  All notices and other communications provided for
herein (including any modifications of, or waivers or consents under,
this Agreement) shall be given or made by telex, telegraph,

in the case of a mailed notice, upon receipt, in each case given or
addressed as aforesaid.

     12.3.     EXPENSES, ETC.  Whether or not any Loan is ever made,
the Company shall pay or reimburse on demand each of the Banks, the
Agent and the Co-Agents for paying:  (a) the reasonable fees and
expenses of Liddell, Sapp, Zivley, Hill & LaBoon, L.L.P., special
counsel to the Agent, and of local counsel to the Agent in the States
of Louisiana, Oklahoma and Alabama in connection with (1) the
preparation, execution and delivery of the Credit Documents (including
the exhibits and schedules hereto), the making of the Loans hereunder
and (2) any modification, supplement or waiver of any of the terms of
any Credit Document; (b) all reasonable out-of-pocket costs and expen-
ses of the Banks, the Agent and the Co-Agents (including costs of
preparing an Independent Engineering Report and reasonable counsels'
fees) in connection with any Event of Default under or the enforcement
of any Credit Document; (c) all transfer, stamp, documentary or other
similar taxes, assessments or charges levied by any governmental or
revenue authority in respect of any Credit Document or any other

assessments and other charges incurred in connection with any filing,
registration, recording or perfection of any security interest
contemplated by this Agreement, any Security Document or any document
referred to herein or therein; and (e) reasonable expenses of due
diligence and syndication, and mutually agreed advertising and
marketing costs.

     12.4.     INDEMNIFICATION.  THE COMPANY SHALL INDEMNIFY THE
AGENT, THE CO-AGENTS, THE BANKS, AND EACH AFFILIATE THEREOF AND THEIR
RESPECTIVE DIRECTORS, OFFICERS, EMPLOYEES, AGENTS AND COUNSEL FROM,
AND HOLD EACH OF THEM HARMLESS AGAINST, ANY AND ALL LOSSES,
LIABILITIES, COSTS, EXPENSES, CLAIMS OR DAMAGES TO WHICH ANY OF THEM
MAY BECOME SUBJECT, REGARDLESS OF AND INCLUDING LOSSES, LIABILITIES,
COSTS, EXPENSES, CLAIMS AND DAMAGES ARISING FROM THE NEGLIGENCE OF THE
AGENT OR THE CO-AGENTS OR THE BANKS OR ANY OTHER INDEMNITEE, INSOFAR
AS SUCH LOSSES, LIABILITIES, COSTS, EXPENSES, CLAIMS OR DAMAGES ARISE
OUT OF OR RESULT FROM ANY (A) ACTUAL OR PROPOSED USE BY THE COMPANY OF
THE PROCEEDS OF ANY EXTENSION OF CREDIT BY ANY BANK HEREUNDER;
(B) BREACH BY THE COMPANY OF ANY CREDIT DOCUMENT (AS DEFINED HEREIN);
(C) VIOLATION BY THE COMPANY 

                                 -100-
<PAGE>

OR ANY OF ITS SUBSIDIARIES OF ANY LEGAL REQUIREMENT INCLUDING, WITHOUT
LIMITATION, APPLICABLE ENVIRONMENTAL LAWS; (D) ANY BANK'S OR THE
AGENT'S OR ANY CO-AGENT'S BEING DEEMED AN OWNER OR OPERATOR OF ANY
ASSETS OF THE COMPANY OR ITS SUBSIDIARIES BY A COURT OR OTHER
REGULATORY OR ADMINISTRATIVE AGENCY OR TRIBUNAL IN CIRCUMSTANCES IN
WHICH NEITHER THE AGENT, EITHER CO-AGENT NOR ANY OF THE BANKS IS
GENERALLY OPERATING OR GENERALLY EXERCISING CONTROL OVER SUCH ASSETS,
TO THE EXTENT SUCH LOSSES, LIABILITIES, CLAIMS OR DAMAGES ARISE OUT OF
OR RESULT FROM ANY LEGAL REQUIREMENT INCLUDING, WITHOUT LIMITATION,
APPLICABLE ENVIRONMENTAL LAWS PERTAINING TO THE CONDITION OF SUCH
ASSETS, (E) ENVIRONMENTAL CLAIMS OR (F) ANY INVESTIGATION, LITIGATION
OR OTHER PROCEEDING (INCLUDING ANY THREATENED INVESTIGATION OR
PROCEEDING) RELATING TO ANY OF THE FOREGOING, and the Company shall
reimburse the Agent, each Co-Agent, each Bank, and each Affiliate
thereof and their respective directors, officers, employees, agents
and counsel, upon demand, for any expenses (including legal fees)
incurred in connection with any such investigation or proceeding; but
excluding any such losses, liabilities, claims, damages, costs or
expenses incurred by a Person or any Affiliate thereof or their
respective directors, officers, employees, agents or counsel by reason
of the gross negligence or willful misconduct of such Person,
Affiliate, director, officer, employee, agent or counsel.  The
obligation of the Company to provide indemnification under this
section for fees and expenses of counsel shall be limited to the fees
and expenses of one counsel in each jurisdiction representing all of
the Persons entitled to such indemnification, except to the extent
that, in the reasonable judgment of any such indemnified Person, the
existence of actual or potential conflicts of interest make
representation of all of such indemnified Persons by the same counsel
inappropriate; in such a case, the Person exercising such judgment
shall be indemnified for the reasonable fees and expenses of its
separate counsel to the extent provided in this Section without giving
effect to the first clause of this sentence.  Nothing in this
SECTION 12.4 is intended to limit the obligations of the Company under
any other provision of this Agreement.

     12.5.     AMENDMENTS, ETC.  No amendment or waiver of any
provision of any Credit Document, nor any consent to any departure by
the Company therefrom, shall in any event be effective unless the same
shall be agreed or consented to by the Required Banks and the Company,
and each such waiver or consent shall be effective only in the
specific instance and for the specific purpose for which given;
PROVIDED that no amendment, waiver or consent shall, unless in writing
and signed by each Bank affected thereby, (a) increase any Commitment
of any of the Banks or subject the Banks to any additional obliga-
tions; (b) reduce the principal of, or interest on, any Loan, fee or
other sum to be paid under any Credit Document; (c) postpone any
scheduled date fixed for any payment of 

                                 -101-
<PAGE>

principal of, or interest on, any Loan, fee or other sum to be paid
under any Credit Document; (d) change the percentage of any of the
Commitments, or of the aggregate unpaid principal amount of any of the
Loans, or the number of Banks which shall be required for the Banks or
any of them to take any action under this Agreement; (e) change any
provision contained in SECTIONS 2.5, 5.2, 5.7, 6, 12.3 or 12.4 or this
SECTION 12.5, or in the definition of "Required Ratios", or (f) except
as provided in the Credit Documents, release any material part of the
security for the obligations of the Company under any Credit Document. 
Except as permitted by the Mortgages, Mortgaged Properties cannot be
sold for consideration other than cash without the approval of all
Banks.  Anything in this SECTION 12.5 to the contrary, no amendment,
waiver or consent shall be made with respect to SECTION 11 without the
consent of the Agent and the Co-Agents.

     12.6.     SUCCESSORS AND ASSIGNS.  (a)  This Agreement shall be
binding upon and inure to the benefit of the Company, the Agent, the
Co-Agents and the Banks and their respective successors and assigns. 
The Company may not assign or transfer any of its rights or
obligations hereunder without the prior written consent of all of the
Banks.

     (b)  Each Bank may sell participations to any Person in all or
part of any Loan, or all or part of its Notes or Commitments, in which
event, without limiting the foregoing, the provisions of SECTION 6
shall inure to the benefit of each purchaser of a participation and
the PRO RATA treatment of payments, as described in SECTION 5.2, shall
be determined as if such Bank had not sold such participation.  In the
event any Bank shall sell any participation, (1) the Company, the
Agent, the Co-Agents and the other Banks shall continue to deal solely
and directly with such selling Bank in connection with such selling
Bank's rights and obligations under the Credit Documents (including
the Notes held by such selling Bank); (2) such Bank shall retain the
sole right and responsibility to enforce the obligations of the
Company relating to the Loans, including the right to approve any
amendment, modification or waiver of any provision of this Agreement
other than amendments, modifications or waivers with respect to (A)
any fees payable hereunder to the Banks, (B) the amount of principal
or the rate of interest payable on, or the dates fixed for the
scheduled repayment of principal of, the Loans and other sums to be
paid to the Banks hereunder, and (C) the release or termination of all
or substantially all of the security for the Loans, and (3) the
Company agrees, to the fullest extent it may effectively do so under
applicable law, that any participant of a Bank may exercise all rights
of set-off, bankers' lien, counterclaim or similar rights with respect
to such participation as fully as if such 

                                 -102-
<PAGE>

participant were a direct holder of Loans if such Bank has previously
given notice of such participation to the Company.

     (c)  Each Bank may assign to one or more Banks or Eligible
Assignees all or a portion of its interests, rights and obligations
under this Agreement (including all or a portion of its Commitments
and the same portion of the related Loans at the time owing to it and
the related Note held by it); PROVIDED (1) other than in the case of
an assignment to a Person at least 50% owned by the assignor Bank, or
by a common parent of both, or to another Bank, the Agent and the
Company must give their respective prior written consent, which
consent will not be unreasonably withheld; (2) the aggregate amount of
the Commitments and/or Loans of the assigning Bank subject to each
such assignment (determined as of the date the Assignment Agreement
with respect to such assignment is delivered to the Agent) shall in no
event be less $10,000,000 (or $1,000,000 in the case of an assignment
between Banks) (except for certain exceptions approved by the Company
and the Agent or where all of a Bank's Commitments and Loans are being
assigned) and shall be in an amount that is an integral multiple of
$1,000,000 (except for certain exceptions approved by the Company and
the Agent or where all of a Bank's Commitments and Loans are being
assigned); (3) the assigning Bank shall contemporaneously assign to
such assignee Bank or Eligible Assignee an equal percentage of the
assigning Bank's Letter of Credit Commitment and all of the assigning
Bank's other rights and obligations under the Letter of Credit
Agreement; and (4) the parties to each such assignment shall execute
and deliver to the Agent, for its acceptance and recording in its
records, an Assignment Agreement with blanks appropriately completed,
together with the Notes subject to such assignment and a processing
and recordation fee of $2,000 (for which the Company shall have no
liability except in the case of assignments required by the Company
pursuant to SECTION 6.1, 6.3 or 6.6, in which case such fee shall be
paid by the Company).  Upon such execution, delivery, acceptance and
recording, from and after the effective date specified in each
Assignment Agreement, (A) the assignee thereunder shall be a party
hereto and, to the extent provided in such Assignment Agreement, have
the rights and obligations of a Bank hereunder, and (B) the Bank
making such assignment shall, to the extent provided in such
assignment, be released from its obligations under this Agreement
(and, in the case of an Assignment Agreement covering all or the
remaining portion of an assigning Bank's rights and obligations under
this Agreement, such Bank shall cease to be a party hereto).

     (d)  By executing and delivering an Assignment Agreement, the
Bank assignor thereunder and the assignee thereunder confirm to and
agree with each other and the other parties hereto as follows:  (1)
other than the representation and warranty that it is the legal and
beneficial owner of the interest being assigned thereby, such 

                                 -103-
<PAGE>

assignor Bank makes no representation or warranty and assumes no
responsibility with respect to any statements, warranties or
representations made in or in connection with any Credit Document or
the execution, legality, validity, enforceability, genuineness,
sufficiency or value of any Credit Document; (2) such assignor Bank
makes no representation or warranty and assumes no responsibility with
respect to the financial condition of the Company or the performance
or observance by the Company of any of its obligations under any
Credit Document; (3) such assignee confirms that it has received a
copy of this Agreement, together with copies of the financial
statements of the Company previously delivered in accordance herewith
and such other documents and information as it has deemed appropriate
to make its own credit analysis and decision to enter into such
Assignment Agreement; (4) such assignee will, independently and
without reliance upon the Agent, such assignor Bank or any other Bank
and based on such documents and information as it shall deem appropri-
ate at the time, continue to make its own credit decisions in taking
or not taking action under the Credit Documents; (5) such assignee
appoints and authorizes the Agent to take such action as agent on its
behalf and to exercise such powers under the Credit Documents as are
delegated to the Agent by the terms hereof, together with such powers
as are reasonably incidental thereto, and (6) such assignee agrees
that it will perform in accordance with their terms all obligations
that by the terms of the Credit Documents are required to be performed
by it as a Bank.

     (e)  The Agent shall maintain at its office a copy of each
Assignment Agreement delivered to it and a record of the names and
addresses of the Banks and the Commitments of, and principal amount of
the Loans owing to, each Bank from time to time.  The entries in such
record shall be conclusive, in the absence of manifest error, and the
Company, the Agent and the Banks may treat each Person the name of
which is recorded therein as a Bank hereunder for all purposes of the
Credit Documents.  Such records shall be available for inspection by
the Company or any Bank at any reasonable time and from time to time
upon reasonable prior notice.

     (f)  Upon its receipt of an Assignment Agreement executed by an
assigning Bank and the assignee thereunder together with the Note
subject to such assignment, the written consent to such assignment and
the fee payable in respect thereto, the Agent shall, if such
Assignment Agreement has been completed with blanks appropriately
filled, (1) accept such Assignment Agreement; (2) record the
information contained therein in its records, and (3) give prompt
notice thereof to the Company.  Contemporaneously with the receipt by
the Agent of an Assignment Agreement, the Company, at its own expense,
shall execute and deliver to the Agent in exchange for each
surrendered Note a new Note payable to the order 

                                 -104-
<PAGE>

of such assignee in an amount equal to the Commitments and/or Loans
assumed by it pursuant to such Assignment Agreement and, if the
assignor Bank has retained Commitments and/or Loans hereunder, new
Notes payable to the order of the assignor Bank in an amount equal to
the Commitments and/or Loans retained by it.  Such new Notes shall be
in an aggregate principal amount equal to the principal amount of each
surrendered Note, shall be dated the effective date of such Assignment
Agreement and shall otherwise be in substantially the form of the
surrendered Notes.  Thereafter, each surrendered Note shall be marked
cancelled and returned to the Company.

     (g)  Any Bank may, in connection with any assignment or
participation or proposed assignment or participation pursuant to this
Section, disclose to the assignee or participant or proposed assignee
or participant any information relating to the Company furnished to
such Bank by or on behalf of the Company.

     (h)  Any assignment by a Bank pursuant to this SECTION 12.6 shall
not result in any single Bank holding in excess of 25% of the
Aggregate Commitment at any one time.

     (i)  Notwithstanding any other provision of this SECTION 12.6,
TCB and its Affiliates may not assign their rights hereunder unless,
after giving effect to such assignment, TCB and its Affiliates would
have an aggregate Commitment Percentage of at least 10%.

     (j)  Notwithstanding anything herein to the contrary, each Bank
may pledge and assign all or any portion of its rights and interests
under the Credit Documents to any Federal Reserve Bank.

     12.7.     SURVIVAL; TERM; REINSTATEMENT.  In addition to the
other provisions of this Agreement expressly stated to survive the
termination of this Agreement, the obligations of the Company under
SECTIONS 6, 12.3 and 12.4 and the last sentence of this SECTION 12.7
and the obligations of the Banks under SECTION 12.8 shall survive the
termination of this Agreement.  The term of this Agreement shall be
until (a) the full and final payment of all Notes, (b) the termination
of all Commitments and (c) the payment of all amounts due under the
Credit Documents.  The Company agrees that if at any time all or any
part of any payment previously applied by any Bank to any Loan or
other sum hereunder is or must be returned by or recovered from such
Bank for any reason (including the order of any bankruptcy court), the
Credit Documents shall automatically be reinstated to the same effect
as if the prior application had not been made, and the Company hereby
agrees to indemnify such Bank against, and to save and hold such Bank
harmless from, any required return by or recovery from such Bank of

                                 -105-
<PAGE>

any such payment because of its being deemed preferential under
applicable Legal Requirements, or for any other reason.  

     12.8.     LIMITATION OF INTEREST.  The parties to this Agreement
intend to strictly comply with all applicable laws, including
applicable usury laws.  Accordingly, the provisions of this
SECTION 12.8 shall govern and control over every other provision of
any Credit Document which conflicts or is inconsistent with this
Section, even if such provision declares that it controls.  As used in
this Section, the term "interest" includes the aggregate of all
charges, fees, benefits or other compensation which constitute
interest under applicable law; PROVIDED that, to the maximum extent
permitted by applicable law, (a) any non-principal payment shall be
characterized as an expense or as compensation for something other
than the use, forbearance or detention of money, and not as interest
and (b) all interest at any time contracted for, taken, reserved,
retained, charged or received shall be amortized, prorated, allocated
and spread, in equal parts during the full term of the Loans and the
Commitments.  In no event shall the Company or any other Person be
obligated to pay, or the Agent or any Bank have any right or privilege
to reserve, receive or retain, (x) any interest in excess of the
maximum amount of nonusurious interest permitted under the laws of the
State of Texas or the applicable laws (if any) of the United States or
of any other state or (y) total interest in excess of the amount which
the Agent or such Bank could lawfully have contracted for, taken,
reserved, received, retained or charged had the interest been
calculated for the full term of the Loans at the Highest Lawful Rate. 
On each day, if any, that the interest rate (the "STATED RATE") called
for under any Credit Document exceeds the Highest Lawful Rate, the
rate at which interest shall accrue shall automatically be fixed by
operation of this sentence at the Highest Lawful Rate for that day,
and shall remain fixed at the Highest Lawful Rate for each day
thereafter until the total amount of interest accrued equals the total
amount of interest which would have accrued if there were no such
ceiling rate as is imposed by this sentence.  Thereafter, interest
shall accrue at the Stated Rate unless and until the Stated Rate again
exceeds the Highest Lawful Rate when the provisions of the immediately
preceding sentence shall again automatically operate to limit the
interest accrual rate.  The daily interest rates to be used in
calculating interest at the Highest Lawful Rate shall be determined by
dividing the applicable Highest Lawful Rate per annum by the number of
days in the calendar year for which such calculation is being made. 
None of the terms and provisions contained in any Credit Document
which directly or indirectly relate to interest shall ever be
construed without reference to this Section, or be construed to create
a contract to pay for the use, forbearance or detention of money at an
interest rate in excess of the Highest Lawful Rate.  If 

                                 -106-
<PAGE>

the term of any of the Notes is shortened by reason of acceleration of
maturity as a result of any Default or by any other cause, or by
reason of any required or permitted prepayment, and if for that (or
any other) reason the Agent or any Bank at any time, including the
stated maturity, is owed or receives (and/or has received) interest in
excess of interest calculated at the Highest Lawful Rate, then and in
any such event all of any such excess interest shall be cancelled
automatically as of the date of such acceleration, prepayment or other
event which produces the excess, and, if such excess interest has been
paid to the Agent or such Bank, it shall be credited PRO TANTO against
the then-outstanding principal balance of the Company's obligations to
the Agent or such Bank, effective as of the date or dates when the
event occurs which causes it to be excess interest, until such excess
is exhausted or all of such principal has been fully paid and
satisfied, whichever occurs first, and any remaining balance of such
excess shall be promptly refunded to its payor.

     12.9.     CAPTIONS.  Captions and section headings appearing
herein are included solely for convenience of reference and are not
intended to affect the interpretation of any provision of this
Agreement.

     12.10.    COUNTERPARTS.  Each Credit Document may be executed in
any number of counterparts, all of which taken together shall consti-
tute one and the same agreement and any of the parties hereto may
execute such Credit Document by signing any such counterpart.

     12.11.    GOVERNING LAW.  EXCEPT TO THE EXTENT OTHERWISE
SPECIFIED THEREIN, EACH CREDIT DOCUMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF TEXAS AND THE
UNITED STATES OF AMERICA.  THE COMPANY HEREBY SUBMITS TO THE
NONEXCLUSIVE JURISDICTION OF THE UNITED STATES DISTRICT COURT FOR THE
SOUTHERN DISTRICT OF TEXAS AND OF ANY TEXAS STATE COURT SITTING IN
HARRIS COUNTY, TEXAS FOR PURPOSES OF ALL LEGAL PROCEEDINGS ARISING OUT
OF OR RELATING TO THE CREDIT DOCUMENTS OR THE TRANSACTIONS
CONTEMPLATED THEREBY.  THE COMPANY IRREVOCABLY WAIVES, TO THE FULLEST
EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER
HAVE TO THE LAYING OF THE VENUE OF ANY SUCH PROCEEDING BROUGHT IN SUCH
A COURT AND ANY CLAIM THAT ANY SUCH PROCEEDING BROUGHT IN SUCH A COURT
HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.

     12.12.    SEVERABILITY.  Whenever possible, each provision of the
Credit Documents shall be interpreted in such manner as to be
effective and valid under applicable law.  If any provision of any
Credit Document shall be invalid, illegal or unenforceable in any
respect under any applicable law, the validity, legality and 

                                 -107-
<PAGE>

enforceability of the remaining provisions of such Credit Document
shall not be affected or impaired thereby.

     12.13.    CHAPTER 15 NOT APPLICABLE.  Chapter 15 of the Texas
Credit Code shall not apply to any Credit Document or to any
Commitment or Loan, nor shall any Credit Document be governed by or be
subject to the provisions of such Chapter 15 in any manner whatsoever.

                                 -108-

     IN WITNESS WHEREOF, the parties hereto have caused this Agreement

                      LETTER OF CREDIT AGREEMENT


     This Letter of Credit Agreement (as amended, modified,
supplemented and restated from time to time, this "AGREEMENT") dated as
of March 16, 1994, is by and among SANTA FE ENERGY RESOURCES, INC.
(the "COMPANY"), a Delaware corporation; each of the lenders which is
or which may from time to time become a signatory hereto (individually
a "BANK" and collectively the "BANKS"); TEXAS COMMERCE BANK NATIONAL
ASSOCIATION ("TCB"), a national banking association, as Administrative
Agent for the Banks (in such capacity, together with its successors in
such capacity, the "AGENT"); and TCB and NATIONSBANK OF TEXAS, N.A., a
national banking association, as Co-Agents (in such capacity, the "CO-
AGENTS").

     The parties agree as follows:

     Section 1.  DEFINITIONS AND ACCOUNTING MATTERS.

     1.1  CERTAIN DEFINED TERMS.  As used herein, the following terms
shall have the following meanings:

     "ACHIEVEMENT DATE" shall mean the first date on which both (a)
the aggregate minimum Qualifying Amount of Junior Securities to be
used in determining the applicable table on EXHIBIT C for the
Preliminary Available Amount has been issued and the gross proceeds
thereof received by the Company and (b) all Designated Debt for the
aggregate Qualifying Amount of Junior Securities actually issued, as
shown on SCHEDULE X, shall have been repaid or Defeased.  In
determining any Achievement Date, the Qualifying Amounts of Junior
Securities issued on such date, on the Qualifying Date and on each
additional date, if any, on which Junior Securities have been issued
shall be aggregated.  For example, if there is only one issuance of
Junior Securities and such issuance is in a Qualifying Amount of
$75,000,000, the Preliminary Available Amount will thereafter be
determined according to Table Four of EXHIBIT C, and the Qualifying
Date and the Achievement Date will be the same.  For example, if there
are two issuances of Junior Securities, one in the amount of
$75,000,000 and a later one in the amount of $50,000,000, the
Qualifying Date will be the date of the first issuance, which will
also be the Achievement Date for the $75,000,000 level in EXHIBIT C,
and the Preliminary Available Amount will be determined according to
Table Four of EXHIBIT C until the date of the second issuance; the
date of the second issuance will be the Achievement Date for the
$125,000,000 level EXHIBIT C, and the Preliminary Available Amount
will thereafter be determined according to Table Two of EXHIBIT F.  An
Achievement Date must occur, if at all, prior to July 1, 1994.

such Calculation Period by (b) the sum of (1) the Alternate Debt
Service of the Company and the Restricted Subsidiaries for such
Calculation Period PLUS (2), at all times and to the extent the
Special Subsidiary Qualifying Conditions are met, the Special
Subsidiary Percentage times the Alternate Debt Service of the Special
Subsidiary for such Calculation Period (in each case calculated on the
basis set forth in the most recent Coverage Report delivered to the
Agent pursuant to SECTION 9.1 and taking into account any incurrence
or prepayment of Covered Debt by the Company or any of the Restricted
Subsidiaries or the Special Subsidiary since the date of such Coverage
Report).

     "ALTERNATE BASE RATE" shall mean, for any date, a rate per annum
(rounded upwards, if necessary, to the next higher 1/100%) equal to
the greater of (a) the Prime Rate in effect on such day or (b) the Fed

Alternate Base Rate due to a change in the Fed Funds Rate shall be
effective on the effective date of such change in the Fed Funds Rate. 
If for any reason the Agent shall have determined (which determination
shall be conclusive absent manifest error) that it is unable to
ascertain the Fed Funds Rate for any reason, including the inability
or failure of the Agent to obtain sufficient bids or publications in
accordance with the terms

hereof, the Alternate Base Rate shall be the Prime Rate until the
circumstances giving rise to such inability no longer exist.

     "ALTERNATE DEBT SERVICE" shall mean, for any Calculation Period
and with respect to any Person, the total of principal payments in
respect of Covered Debt of such Person and the total of interest
payments (using, with respect to interest to accrue, the interest

such Covered Debt bears interest at one or more fixed rates as of the
date of determination of Alternate Debt Service but such Covered Debt
will not bear interest at such fixed rate or rates to the end of such
Calculation Period, then interest payments in respect of Alternate
Debt Service with respect to such Covered Debt shall be calculated on
the basis of such fixed rate or rates for such time as the same shall
be applicable to such Covered Debt, and then at the interest rates set

Debt of such Person, in each case paid and scheduled to be paid during
such Calculation Period; PROVIDED that the principal amount of any
Covered Debt of such Person which by its terms matures on a date

of credit issued for the account of a Person will be fully drawn upon
their respective expiry dates, (b) the reimbursement obligations of a

of determination and for the Calculation Period in which such date
occurs and for each Calculation Period thereafter to and including the
Calculation Period including the Termination Date, the lowest of the

basis of the Most Recent Engineering Report) for such Calculation
Period by (b) the sum of (1) the Debt Service of the Company and the
Restricted Subsidiaries for such Calculation Period PLUS (2), at all
times and to the extent the Special Subsidiary Qualifying Conditions
are met, the Special Subsidiary Percentage times the Debt Service of
the Special Subsidiary for such Calculation Period (in each case
calculated on the basis set forth in the most recent Coverage Report
delivered to the Agent pursuant to SECTION 9.1 and taking into account

     Section 2.  COMMITMENTS.

     2.1  LETTERS OF CREDIT.  (a)  COMMITMENTS.  Subject to the terms
and conditions of this Agreement, the Agent agrees, upon receipt by
Agent of an Application therefor, to issue, and each Bank severally
agrees to purchase from the Agent a participation in (according to
such Bank's Commitment Percentage), letters of credit containing such
provisions not inconsistent with the terms of this Agreement as the
Company may reasonably request and such provisions not inconsistent
with the terms of this Agreement as the Banks may reasonably require
(together with the Existing Letters of Credit, the "LETTERS OF
CREDIT") for the account of the Company and on behalf of the Company,
or for the joint and several account of and on behalf of the Company
and one or more of its Subsidiaries, as follows.  From time to time on
or after the conditions herein set forth to issue such Letters of
Credit have been satisfied, and prior to the Termination Date, the
Agent shall issue and/or may have outstanding Letters of Credit under
this SECTION 2.1 in an aggregate principal amount at any one time
outstanding (including all Letter of Credit Liabilities at such time)
up to but not exceeding the lesser of (1) $15,000,000 (as adjusted
downward from time to time in accordance herewith) or (2) the lesser
of (I) the Available Amount and (II) the aggregate Facility B
Commitments less (in each case of (I) and (II)) the aggregate unpaid
principal balance of the Facility B Notes; PROVIDED, that the
aggregate Letter of Credit Liabilities at any one time outstanding
together with the aggregate principal amount of Facility B Loans at
any time outstanding shall never exceed the Available Amount then in
effect and PROVIDED, that anything to the contrary in this Agreement
notwithstanding, the Agent shall have no obligation to issue any
Letter of Credit on or after the Termination Date.  Upon the date of
the issuance of a Letter of Credit on or after the date hereof, 

                                 -32-
<PAGE>

the Agent shall be deemed, without further action by any party hereto,
to have sold to each Bank, and each Bank shall be deemed, without
further action by any party hereto, to have purchased from the Agent,
a participation, to the extent of such Bank's Commitment Percentage,
in such Letter of Credit and the related Letter of Credit Liabilities. 
No Letter of Credit issued pursuant to this Agreement shall have an
expiry date later than one year from date of issuance.  Each Bank has
heretofore purchased participations in each of the Existing Letters of
Credit and the related Letter of Credit Liabilities, to the extent of
such Bank's Commitment Percentage.  Such participations are hereby
ratified and confirmed and made subject hereto.  All provisions of
this Agreement applicable to participations in Letters of Credit
hereunder shall be deemed to apply to participations in the Existing
Letters of Credit.

     (b)  ADDITIONAL PROVISIONS.  The following additional provisions
shall apply to each Letter of Credit:

     (i)  The Company shall give the Agent and each other Bank at
least five Business Days' irrevocable prior notice (effective upon
receipt) specifying the date such Letter of Credit is to be issued and
describing the proposed terms of such Letter of Credit and the nature
of the transaction proposed to be supported thereby.  The Company
shall furnish such additional information regarding such transaction
as the Agent may reasonably request.  Upon receipt of such notice, the
Agent shall promptly notify each Bank of such Bank's Commitment
Percentage of the amount of the proposed Letter of Credit and not
later than two Business Days prior to the requested issuance date for
such Letter of Credit shall furnish to each Bank and the Company a
proposed form of an Application for such Letter of Credit.  The
issuance by the Agent of each Letter of Credit shall, in addition to
the conditions precedent set forth in SECTION 7, be subject to the
conditions precedent that such Letter of Credit shall be in such form
and contain such terms as shall be reasonably satisfactory to the
Agent and that the Company shall have executed and delivered to the
Agent an Application and such other instruments and agreements
relating to such Letter of Credit not inconsistent with terms of this
Agreement as the Agent shall have reasonably requested and are not
inconsistent with the terms of this Agreement.  

     (ii) No Letter of Credit may be issued if after giving effect
thereto the sum of (a) the aggregate outstanding principal amount of
the Facility B Loans plus (b) the aggregate Letter of Credit
Liabilities would exceed the Available Amount.  On each day during the
period commencing with the issuance of any Letter of Credit and until
such Letter of Credit shall have expired or been terminated, the
Facility B Commitment of each Bank shall be deemed to be utilized for
all purposes hereof in an amount equal to such Bank's Commitment
Percentage of the amount then or thereafter available for drawings
under such Letter of Credit.

                                 -33-
<PAGE>

     (iii) In consideration of the issuance of each Letter of Credit
the Company agrees to pay to the Agent, for the ratable benefit of the
Banks, the Letter of Credit Fee.  The Letter of Credit Fee shall be
payable concurrently with the issuance of each such Letter of Credit
and shall be separate from and in addition to interest on any
Reimbursement Obligation.  The Agent will pay to each Bank, promptly
after receiving any payment in respect of Letter of Credit Fees, an
amount equal to such Bank's Commitment Percentage of such Letter of
Credit Fees.

     (iv) Upon receipt from the beneficiary of any Letter of Credit of
any demand for payment thereunder, the Agent shall promptly notify the
Company and each Bank as to the amount to be paid as a result of such
demand and the payment date.  If at any time the Agent shall have made
a payment to a beneficiary of a Letter of Credit in respect of a
drawing or in respect of an acceptance created in connection with a
drawing under such Letter of Credit, each Bank will pay to the Agent
immediately upon demand (or, if such demand is made after 1:00 p.m.,
on the next succeeding Business Day) by the Agent at any time during
the period commencing after such payment until reimbursement thereof
in full by the Company, an amount equal to such Bank's Commitment
Percentage of such payment, together with interest on such amount for
each day from the later of (x) the date such payment is due as
provided in the preceding sentence or (y) the date such payment is
made under such Letter of Credit to the date of payment by such Bank
of such amount at a rate of interest per annum equal to the Fed Funds
Rate for such period.  No interest shall be due from any Bank that
makes full payment to the Agent on the date such payment is due. 
Nothing herein shall be deemed to require any Bank to pay to the Agent
any amount as reimbursement for any payment made by the Agent to
acquire (discount) for its own account prior to maturity thereof any
acceptance created under a Letter of Credit.

     (v)  The Company shall be irrevocably and unconditionally
obligated forthwith to reimburse the Agent for the account of each
Bank for any amount paid by the Agent or such Bank upon any drawing
under any Letter of Credit, without presentment, demand, protest or
other formalities of any kind all of which are hereby expressly waived
by the Company.  Each drawing under any Letter of Credit shall bear
interest at the Post-Default Rate until the Company shall have made
reimbursement for such drawing.  If the Company shall fail to make
reimbursement for any such drawing prior to noon on the second
Business Day after such notice is given, the Agent may in its
discretion and without the consent of (but with concurrent notice to)
the Company effect such reimbursement of any Letter of Credit, subject
to the satisfaction of the conditions in SECTION 7 of the Amended and
Restated Revolving Credit Agreement and to the existence of Facility B
Commitment, by borrowing of Facility B Loans and the application of
the proceeds thereof to the related Reimbursement Obligations.  The
Reimbursement Obligations shall survive the Termination Date and the
termination of this 

                                 -34-
<PAGE>

Agreement.  The Agent will pay to each Bank such Bank's Commitment
Percentage of all amounts received from the Company for application in
payment, in whole or in part, of the Reimbursement Obligation in
respect of any Letter of Credit, but only to the extent such Bank has
made payment to the Agent in respect of such Letter of Credit pursuant
to CLAUSE (iv) above.  Nothing herein shall be deemed to require the
Agent to pay to any Bank any part of the proceeds of disposition
(rediscount) by the Agent for its own account to any other Person of
any acceptance created under a Letter of Credit which is acquired
(discounted) by the Agent prior to the maturity thereof or to require
any Bank to reimburse the Agent for the consequences of the Agent's
own gross negligence or willful misconduct.

     (vi) The obligations of the Company to pay Reimbursement
Obligations under this Agreement shall be absolute, unconditional and
irrevocable and shall be paid or performed strictly in accordance with
the terms of this Agreement under all circumstances whatsoever,
including, without limitation, the following circumstances:

          (a)  any lack of legality, validity, regularity or
enforceability of this Agreement, any Letter of Credit, any
Application or any agreement or document related to any of the
foregoing; 

          (b)  any amendment or waiver of (including any default), or
any consent to departure from, any Letter of Credit, this Agreement,
any Application or any agreement or document related to any of the
foregoing;

          (c)  the existence of any claim, set-off, defense or other
rights which the Company may have at any time against any beneficiary
or any transferee of any Letter of Credit (or any Persons or entities
for which such beneficiary or any such transferee may be acting), the
Agent, any Bank or any other Person, whether in connection with this
Agreement, any Letter of Credit, any Application or any agreement or
document related to any of the foregoing, the transactions
contemplated hereby or any unrelated transaction;

          (d)  any statement, certificate, draft or any other document
presented under any Letter of Credit proves to have been forged,
fraudulent, invalid or insufficient in any respect or any statement
therein proves to have been untrue or inaccurate in any respect
whatsoever;

          (e)  payment by the Agent under any Letter of Credit against
presentation of a draft or certificate which appears on its face to
comply but does not in fact comply with the terms of such Letter of
Credit; 

                                 -35-
<PAGE>

          (f)  any defense based upon the failure of any beneficiary
or any transferee to receive all or any part of the proceeds of a draw
under any Letter of Credit transmitted by the Agent, or any non-
application or misapplication by any beneficiary or other transferee
of the proceeds of demand for payment under any Letter of Credit; and

          (g)  any bankruptcy, insolvency, reorganization,
arrangement, assignment for the benefit of creditors, readjustment of
debt, dissolution, liquidation or other similar event with respect to
the Company.

PROVIDED, that no such payment shall impair any claim the Company may
have against the Agent or any Bank.

     (c)  ILLEGALITY.  In the event that any restriction or limitation
is imposed upon or determined or held to be applicable to the Agent,
any Bank or the Company by, under or pursuant to any Legal
Requirement, which in the reasonable judgment of the Agent or any Bank
would prevent the Agent or such Bank from legally incurring liability
under or in respect of a Letter of Credit issued or proposed to be
issued hereunder, then the Agent shall give prompt written notice
thereof to the Company, whereupon the Agent and the Bank or Banks
affected shall have no obligation to issue or purchase participations
in any such Letter of Credit.

     2.2  AVAILABLE AMOUNT.

          (a)  Concurrently with the delivery of each Independent

Upon each such delivery, the Company may by notice to the Co-Agents
designate as the Available Amount any amount (not to exceed the
Preliminary Available Amount as of the most recent Achievement Date

then in effect), according to the applicable table in EXHIBIT C equal
to or less than such total maximum amount.  The Available Amount so
designated shall remain in effect as the Available Amount until the
next determination under this SECTION 2.2.  If no amount lesser than
(a) or (b) in this sentence is designated in accordance with this
SECTION 2.2, the Available Amount shall be the lesser of (a) the
Preliminary Available Amount then in effect according to the
applicable table in EXHIBIT C or (b) such total maximum amount.

          (b)  Notwithstanding anything in this Agreement to the
contrary, (1) no Bank shall be required to have aggregate Letters of
Credit Liabilities at any one time outstanding in excess of such
Bank's Commitment Percentage of the lesser of (x) $15,000,000 and 

                                 -36-
<PAGE>

(y) the difference between (i) the Available Amount and (ii) the
aggregate Facility B Loans, and (2) if a Bank fails to participate in
a Letter of Credit as and when required hereunder and the Company
subsequently makes a repayment on the Reimbursement Obligations with
respect to such Letter of Credit, such repayment shall be split among
the non-defaulting Banks ratably in accordance with their respective
Commitment Percentages until each Bank has its Commitment Percentage
of all of the outstanding Reimbursement Obligations, and the balance
of such repayment shall be divided among all of the Banks in
accordance with their respective Commitment Percentages. 

          (c)  Notwithstanding anything in this Agreement to the
contrary, the Agent shall not be required to issue any Letter of
Credit during the existence of an Engineering Shortfall.

          (d)  The Company may from time to time at its option,
exercisable by giving written notice to the Co-Agents not more often

Assumptions, which shall be furnished to the Banks by a notice as
provided in the definition of "Approved Assumptions" and shall be
subject to the approval by Banks with aggregate Commitment Percentages
of 75% or more as provided therein.  The Optional Reserve Report shall
be based on the new Approved Assumptions and shall be accompanied by a
Coverage Report as of the date such Optional Reserve Report is
furnished.  The Annual Debt Service Coverage Ratio, the Alternate
Annual Debt Service Coverage Ratio, the TLOR Coverage Ratio and the
SLOR Coverage Ratio shall each be redetermined in accordance with this
Agreement on the basis of each such Optional Reserve Report and
Coverage Report, and the Available Amount recalculated as provided in
this SECTION 2.2.

          (e)  Notwithstanding any other provision of this Agreement
to the contrary, should both (x) the Company at any time designate as
the Available Amount an amount less than the maximum amount then
offered to it as the Available Amount by the Co-Agents and (y) as a
result the Company shall obtain the release of any Mortgaged
Properties under the Amended and Restated Revolving Credit Agreement,
the Available Amount may never thereafter exceed the amount so
designated by the Company.

     2.3  REDUCTIONS AND CHANGES OF COMMITMENTS.

     (a)  MANDATORY.  On the Termination Date the aggregate
Commitments shall be terminated in their entirety.

     (b)  THE COMPANY'S OPTION.  The Company shall have the right to
terminate or reduce the unused portion of the Commitments at any time
or from time to time; PROVIDED that:  (i) the Company shall give
notice of each such termination or reduction to the Agent as 

                                 -37-
<PAGE>

provided in SECTION 5.5; (ii) each such partial reduction shall be in
minimum increments equal to $5,000,000; and (iii) the Company may not
cause the Available Amount to be less than the aggregate principal
amount of the Facility B Loans then outstanding plus the Letter of
Credit Liabilities then outstanding.  Any voluntary reduction in the
Available Amount prior to any scheduled reduction in the Available
Amount shall not affect the Available Amount after such scheduled
reduction date unless such voluntarily reduced Available Amount is
less than the amount scheduled to be the Available Amount after such
scheduled reduction date, in which case the Available Amount after
such scheduled reduction date shall be no greater than such
voluntarily reduced Available Amount.  Reference is made to
SECTION 2.8 of the Amended and Restated Revolving Credit Agreement for
restrictions on the Company's right to increase the Available Amount
under certain circumstances.

     (c)  NO REINSTATEMENT.  No reduction in or termination of
Commitments pursuant to this Section may be reinstated without the
written approval of the Agent and all Banks.

     2.4  SEVERAL OBLIGATIONS.  The failure of any Bank to participate
in any Letter of Credit shall not relieve any other Bank of its
obligation to participate in any Letter of Credit (the face amount of
which shall be reduced dollar for dollar by the amount of the share of
the Bank that failed to participate in such Letter of Credit) on such
date, but neither the Agent nor any Bank shall be responsible for the
failure of any other Bank to participate in any Letter of Credit.

     2.5  FEES.  In consideration of the Commitments, the Company
shall pay to the Agent for the account of each Bank in accordance with
its Commitment Percentage commitment fees (the "COMMITMENT FEES") for

Commitment.  The Company shall be entitled to credit on the Commitment
Fees any amount paid pursuant to SECTION 2.3 of the Amended and
Restated Revolving Credit Agreement.  The Commitment Fees shall be
computed for each day and shall be based on the Unused Commitment for
such day.  Accrued Commitment Fees shall be payable in arrears on the
date of the initial Letter of Credit, within three days after demand
therefor on or about the Quarterly Dates, and within three days after
demand therefor on or about the Termination Date.  All past due
Commitment Fees shall bear interest at the Post-Default Rate.  Upon
receipt, the Agent shall disburse the Commitment Fees to the Banks in
accordance with their Commitment Percentages.

     3.1  (a)  COMMITMENT AMOUNT.  The Company shall from time to time
on demand by the Agent prepay the Facility B Loans or reduce 
                                 -38-
<PAGE>

Letter of Credit Liabilities in such amounts as shall be necessary (A)
so that at all times the aggregate outstanding principal amount of all
Facility B Loans and all Letter of Credit Liabilities hereunder shall
not be in excess of the aggregate of the Available Amount or (B) to
comply with SECTION 9.9.  Any such payment shall be allocated between
Facility B Loans, Letter of Credit Liabilities (and if to Letter of
Credit Liabilities, first, to Reimbursement Obligations) and other
obligations as the Company may elect.

     (b)  AVAILABLE AMOUNT.  The Company shall from time to time on
demand by the Agent and on the Termination Date prepay the Facility B
Loans or reduce Letter of Credit Liabilities in such amounts as shall
be necessary so that at all times the aggregate outstanding principal
amount of all Facility B Loans and all Letter of Credit Liabilities of
the Company hereunder shall be less than or equal to the Available
Amount.  Any such payment shall be allocated between Facility B Loans,
Letter of Credit Liabilities (and if to Letter of Credit Liabilities,
first, to Reimbursement Obligations) and then to other obligations as
the Company may elect.

     Section 4.  PAYMENTS OF PRINCIPAL AND INTEREST.

     4.1  REPAYMENT OF REIMBURSEMENT OBLIGATIONS.  The Company will
pay to the Agent for the account of each Bank the amount of each
Reimbursement Obligation forthwith upon its incurrence.  The amount of
any Reimbursement Obligation may, if the applicable conditions
precedent specified in SECTION 7 of the Amended and Restated Revolving
Credit Agreement have been satisfied, be paid with the proceeds of
Facility B Loans.  

     4.2  INTEREST.  Subject to SECTION 12.8, the Company will pay to
the Agent for the account of each Bank interest on the unpaid
principal amount of each Reimbursement Obligation owed to such Bank
for the period commencing on the date such Reimbursement Obligation
arises to but excluding the date such Reimbursement Obligation shall
be paid in full, at the Post-Default Rate.

     Accrued interest shall be due and payable from time to time on
demand of the Agent or the Required Banks (through the Agent).

     Section 5.  PAYMENTS; PRO RATA TREATMENT; COMPUTATIONS, ETC.

     5.1  PAYMENTS.  (a)  Except to the extent otherwise provided
herein, all payments of principal of or interest on the Reimbursement
Obligations and other amounts to be made by the Company hereunder
shall be made in dollars, in immediately available funds, to the Agent
at its Principal Office (or in the case of a successor Agent, at the
principal office of such successor Agent in the United States), not
later than 11:00 a.m. on the date on which such payment shall become
due (each such payment made after such time on such due date to be
deemed to have been made on the next succeeding Business Day).

                                 -39-
<PAGE>

     (b)  The Company shall, at the time of making each payment
hereunder, specify to the Agent the Reimbursement Obligations or other
amounts payable by the Company hereunder to which such payment is to
be applied (and in the event that it fails so to specify, such payment
shall be applied as the Agent may designate to the amounts then due
and payable); PROVIDED that if no Reimbursement Obligations are then
due and payable or an Event of Default has occurred and is continuing,
the Agent may apply such payment to the Obligations in such order as
it may elect in its sole discretion, but subject to the other terms
and conditions of this Agreement, including SECTION 5.2).  Each
payment received by the Agent hereunder for the account of a Bank
shall be paid promptly to such Bank, in immediately available funds
for the account of such Bank's Applicable Lending Office.  

     (c)  If the due date of any payment hereunder falls on a day
which is not a Business Day, the due date for such payment shall be
extended to the next succeeding Business Day and interest shall be
payable for any principal so extended for the period of such
extension.

     5.2  PRO RATA TREATMENT.  Except to the extent otherwise provided
herein, (a) each issuance of a Letter of Credit and each termination
or reduction of the Commitments of the Banks under SECTION 2.3 shall
be made PRO RATA according to the Banks' respective Commitments; (b)
each payment by the Company of principal of or interest on any
Reimbursement Obligation shall be made to the Agent for the account of
the Banks PRO RATA in accordance with the respective unpaid principal
amounts of such Reimbursement Obligation held by the Banks; and (c)
the Banks (other than the Agent) shall purchase from the Agent
participations in the Letters of Credit in accordance with their
respective Commitment Percentages.

     5.3  COMPUTATIONS.  Interest based on the Alternate Base Rate (to
the extent determined by reference to the Prime Rate), and fees
hereunder, will be computed on the basis of 365 (or 366) days and
actual days elapsed (including the first day but excluding the last
day) occurring in the period for which payable.  All other interest
shall be computed on the basis of a year of 360 days and actual days
elapsed (including the first day but excluding the last day) occurring
in the period for which payable, unless the effect of so computing
shall be to cause the rate of interest to exceed the Highest Lawful
Rate (in which event interest shall be calculated on the basis of the
actual number of days elapsed in a year composed of 365 or 366 days,
as the case may be).

     5.4  MINIMUM AND MAXIMUM AMOUNTS.  Each Letter of Credit shall be
in a face amount at least equal to $100,000.

     5.5  CERTAIN ACTIONS, NOTICES, ETC.  Notices to the Agent of any
termination or reduction of Commitments, prepayments under

                                 -40-
<PAGE>

SECTION 3.1 and requests for the issuance of Letters of Credit shall
be irrevocable and shall be effective only if received by the Agent
not later than 11:00 a.m. on the number of Business Days prior to the
date of the relevant issuance, termination, reduction, and/or
prepayment specified below:

                                   Number of Business
                                        Days Prior   
                                          NOTICE     

     Termination or reduction
     of Commitments                         10

     Issuance of Letters of Credit           5

     Prepayments                             1

Each such notice of termination or reduction shall specify the amount
of the Commitments to be terminated or reduced.  Each such notice of
prepayment shall specify the amount to be prepaid (subject to SECTION
3.1) and the date of prepayment (which shall be a Business Day).  The
Agent shall promptly notify the Banks of the contents of each such
notice or Application.  Notice of any prepayment having been given,
the principal amount specified in such notice, together with interest
thereon to the date of prepayment, shall be due and payable on such
prepayment date.

     5.6  NON-RECEIPT OF FUNDS BY THE AGENT.  Unless the Agent shall
have been notified by a Bank prior to noon on the date on which such
Bank is to make payment to the Agent of any amount to be paid by such
Bank to reimburse the Agent for a drawing under any Letter of Credit
or by the Company prior to the date on which the Company is to make a
payment to the Agent for the account of one or more of the Banks, as
the case may be (such Bank or the Company being herein called the
"PAYOR" and such payment being herein called the "REQUIRED PAYMENT"),
which notice shall be effective upon receipt, that the Payor does not
intend to make the Required Payment to the Agent, the Agent may assume
that the Required Payment has been made and may, in reliance upon such
assumption (but shall not be required to), make the amount thereof
available to the intended recipient on the date that such Required
Payment is to be made.  If the Payor is the Company and the Company
has not in fact made the Required Payment to the Agent on or before
such date, the recipient of such payment (or, if the recipient is the
beneficiary of a Letter of Credit, the Company, and, if the Company
fails to pay the amount thereof to the Agent on demand, then the
Banks, to the extent not already paid, ratably in proportion to their
respective Commitment Percentages) shall, on demand, pay to the Agent
the amount made available by the Agent, together with interest thereon
from the date such amount was so made available by the Agent until the
date the Agent recovers such amount at a rate per annum equal to the
Fed Funds Rate for the first three days 

                                 -41-
<PAGE>

after demand and thereafter at the Fed Funds Rate plus 2%.  If the
Payor is a Bank and such Bank has not in fact made the Required
Payment to the Agent on or before such date, then such Bank shall pay
to the Agent the amount made available by the Agent on behalf of such
Bank, together with interest thereon from the date such amount was so
made available by the Agent until the Agent recovers such amount at a
rate per annum equal to the Fed Funds Rate for the first three days
and thereafter at the Fed Funds Rate plus 2%.

     5.7  SHARING OF PAYMENTS, ETC.  If a Bank or any participant of a
Bank shall obtain payment of any obligation to it under this
Agreement, through the exercise of any right of set-off, banker's
lien, counterclaim or similar right, or otherwise, then such Bank or
participant shall promptly purchase from the other Banks participa-
tions in the Reimbursement Obligations or other obligations held by
the other Banks in such amounts, and make such other adjustments from
time to time as shall be equitable to the end that all the Banks and
participants shall share the benefit of such payment (net of any
expenses which may be incurred by such Bank or its participant in
obtaining or preserving such benefit) PRO RATA in accordance with the
unpaid principal and interest on such obligations then due to each of
them.  To such end all the Banks and their participants shall make
appropriate adjustments among themselves (by the resale of
participations sold or otherwise) if such payment is rescinded or must
otherwise be restored.  The Company agrees, to the fullest extent it
may effectively do so under applicable law, that any Bank so
purchasing a participation in the Reimbursement Obligations or other
obligations held by other Banks may exercise all rights of set-off,
bankers' lien, counterclaims or similar rights with respect to such
participation as fully as if such Bank were a direct holder of
Reimbursement Obligations or other obligations in the amount of such
participation.  Nothing contained herein shall require any Bank to
exercise any such right or shall affect the right of any Bank to
exercise, and retain the benefits of exercising, any such right with
respect to any other indebtedness or obligation of the Company.

     5.8  OTHER EXPENSES.  The Company agrees to pay the Agent, for
the account of the Agent, the usual and customary charges of TCB for
each extension, amendment and wire advice of and drawing under the
Letters of Credit.

     Section 6.  YIELD PROTECTION AND ILLEGALITY.  

     6.1  ADDITIONAL COSTS IN RESPECT OF LETTERS OF CREDIT.  If as a
result of any Regulatory Change there shall be imposed, modified or
deemed applicable any tax, reserve, special deposit or similar
requirement against or with respect to or measured by reference to
Letters of Credit issued or to be issued hereunder and the result
shall be to increase the cost to the Agent or any Bank of issuing or
maintaining or participating in any Letter of Credit or reduce 

                                 -42-
<PAGE>

any amount receivable by the Agent or any Bank hereunder in respect of
any Letter of Credit or participation therein, then such Bank shall
notify the Company through the Agent, and upon demand therefor by such
Bank through the Agent, the Company (subject to SECTION 12.8) shall
pay to the Agent or such Bank, from time to time as specified by the
Agent or such Bank, such additional amounts as shall be sufficient to
compensate the Agent or such Bank for such increased costs or
reductions in amount.  Before making such demand pursuant to this
SECTION 6.1, the Agent or such Bank will designate a different
available Applicable Lending Office for the Letter of Credit or
participation or take such other action as the Company may request, if
such designation or action will avoid the need for, or reduce the
amount of, such compensation and will not, in the sole opinion of the
Agent or such Bank, be disadvantageous to the Agent or such Bank.  A
statement as to such increased costs or reductions in amount incurred
by the Agent or such Bank, submitted by the Agent or such Bank to the
Company, shall cover amounts accruing under this section with respect
to a period beginning not earlier than 120 days from the date thereof
and be conclusive as to the amount thereof, absent manifest error.

     In the event any Bank shall seek compensation pursuant to this
SECTION 6.1, the Company may give notice to such Bank (with copies to
the Agent) that it wishes to seek one or more Eligible Assignees
(which may be one or more of the Banks) to assume the Commitment of
such Bank and to purchase and assume its outstanding Letter of Credit
Liabilities.  Each Bank requesting compensation pursuant to this
SECTION 6.1 agrees to sell its Commitment and interest in this
Agreement and in the Obligations and in the Amended and Restated
Revolving Credit Agreement pursuant to SECTION 12.6 (without recourse,
representation or warranty except as provided in SECTION 12.6)  to any
such Eligible Assignee for an amount equal to the sum of the
outstanding unpaid principal of and accrued interest on such
Obligations plus all other fees and amounts (including any
compensation claimed by such Bank under this SECTION 6.1) owing to
such Bank hereunder and under the Amended and Restated Revolving
Credit Agreement calculated, in each case, to the date such
Commitment, Obligations and interests are purchased, whereupon such
Bank shall have no further Commitment or other obligation to the
Company hereunder or under the Amended and Restated Revolving Credit
Agreement.

     6.2  CAPITAL ADEQUACY.  If any Bank shall have determined that
the adoption after the date hereof or effectiveness after the date
hereof (regardless of whether previously announced) of any applicable
Legal Requirement or treaty regarding capital adequacy, or any change
after the date hereof in any existing or future Legal Requirement or
treaty regarding capital adequacy, or any change in the interpretation
or administration thereof after the date hereof by any Governmental
Authority or comparable agency charged with the interpretation or
administration thereof, or compliance by any Bank (or its Applicable
Lending Office) with any request or directive 

                                 -43-
<PAGE>

after the date hereof regarding capital adequacy (whether or not
having the force of law) of any such Governmental Authority or
comparable agency has or would have the effect of reducing the rate of
return on the capital of such Bank (or any holding company of which
such Bank is a part) as a consequence of its obligations hereunder and
under or in respect of the Letters of Credit to a level below that
which such Bank or holding company could have achieved but for such
adoption, change or compliance by an amount deemed by such Bank to be
material, then from time to time, upon demand by such Bank (with a
copy to the Agent), the Company (subject to SECTION 12.8) shall pay to
such Bank such additional amount or amounts as will compensate such
Bank or holding company for such reduction.  The certificate of any
Bank setting forth such amount or amounts as shall be necessary to
compensate it and the basis therefor shall cover amounts accruing
under this SECTION 6.2 with respect to a period beginning not earlier
than 120 days from the date thereof and shall be conclusive and
binding, absent manifest error.  The Company shall pay the amount
shown as due on any such certificate upon delivery of such
certificate.  In preparing such certificate, a Bank may employ such
assumptions and allocations of costs and expenses as it shall in good
faith deem reasonable and may use any reasonable averaging and
attribution method.  In the event any Bank shall seek compensation
pursuant to this SECTION 6.2, the Company may give notice to such Bank
(with copies to the Agent) that it wishes to seek one or more Eligible
Assignees (which may be one or more of the Banks) to assume the
Commitment of such Bank and to purchase and assume its outstanding
Letter of Credit Liabilities.  Each Bank requesting compensation
pursuant to this SECTION 6.2 agrees to sell its Commitment and
interest in this Agreement and in the Obligations and in the Amended
and Restated Revolving Credit Agreement pursuant to SECTION 12.6
(without recourse, representation or warranty except as provided in
SECTION 12.6) to any such Eligible Assignee for an amount equal to the
sum of the outstanding unpaid principal of and accrued interest on
such Obligations plus all other fees and amounts (including any
compensation claimed by such Bank under this SECTION 6.2) owing to
such Bank hereunder and under the Amended and Restated Revolving
Credit Agreement calculated, in each case, to the date such
Commitment, Obligations, and interests are purchased, whereupon such
Bank shall have no further Commitment or other obligation to the
Company hereunder or under the Amended and Restated Revolving Credit
Agreement.

would not individually or in the aggregate have a material adverse
effect on the business, financial condition or results of operations
of the Combined Group taken as a whole.

     8.2  INFORMATION.

     (a)  (i)  The most recent consolidated balance sheet of the
Company and its Subsidiaries and the related consolidated statements

there are no legal or arbitral proceedings or any proceedings by or

Legal Requirement (including any securities law, rule or regulation)
applicable to the Company or any of its Subsidiaries or (except for
the Liens required or permitted by this Agreement) result in the
creation or imposition of any Lien upon any of the revenues or

which it is subject, or constitute a default under any such agreement
or instrument.

of the Credit Documents by the Company have been duly authorized by
all necessary corporate action.  The Credit Documents have been duly
and validly executed and delivered by the Company and constitute the
legal, valid and binding obligations of the Company, enforceable in

conveyance, reorganization, moratorium or other similar laws relating
to the enforcement of creditors' rights generally and by general
equitable principles.

to acquire or carry, directly or indirectly, any such margin stock.

     8.8  ERISA.  The Company and each ERISA Affiliate have fulfilled
their contribution obligations under each Plan subject to Title IV of
ERISA and have fulfilled their obligations under the minimum funding
standards of ERISA and the Code with respect to each Plan subject to
Title IV of ERISA, and in all other regard with respect to each Plan
are in material compliance with the applicable provisions of ERISA,
the Code, and all other applicable laws, regulations and rules, to the
extent that noncompliance with such provisions would result in a
Material Adverse Change.  The Company has no knowledge of any event
with respect to each Plan which could result in a Material Adverse
Change.

     8.9  TAXES.  Each of the Company and its Subsidiaries has filed
all United States federal income tax returns and all other material
tax returns which are required to be filed by it and has paid all
taxes due pursuant to such returns or pursuant to any assessment

assets by the Company to a wholly owned Restricted Subsidiary or by a
Restricted Subsidiary to the Company or to another wholly owned
Restricted Subsidiary; PROVIDED that if the Company is the seller
under any such Sale and Leaseback Transaction, its lease obligations
thereunder shall be subordinated to the Obligations represented by the

Subsidiary's liability with respect to taxes as a result of the filing
of any such consolidated income tax return with such Person 

                                 -67-

protest or other formalities of any kind, all of which are hereby
expressly WAIVED by the Company; PROVIDED that in the case of the

     Section 11.  THE AGENT.

     11.1 APPOINTMENT, POWERS AND IMMUNITIES.  Each Bank hereby
irrevocably appoints and authorizes the Agent to act as its Agent
under the Credit Documents and under the Letters of Credit with such
powers as are specifically delegated to the Agent by the terms
thereof, together with such other powers as are reasonably incidental
thereto, including the execution and delivery of the First Amendment
to Deed of Trust (as that term is defined in the Amended and Restated
Revolving Credit Agreement).  The Agent (which term as used in this
SECTION 11 shall include reference to its Affiliates and its own and
its Affiliates' officers, directors, employees and agents) shall (a)
have no duties or responsibilities except those expressly set forth in
the Letters of Credit and the Credit Documents, and shall not by
reason of any Credit Document be a trustee or fiduciary for any Bank;
(b) not be responsible to any Bank for any recitals, statements,
representations or warranties contained in any Credit Document, or in
any certificate or other document referred to or provided for in, or
received by any of them under, any Credit Document, or for the value,
validity, effectiveness, genuineness, enforceability or sufficiency of
any Credit Document or any other document referred to or provided for
therein or any property covered thereby or for any failure by the
Company or any other Person to perform any of its obligations
thereunder; (c) not be required to initiate or conduct any litigation
or collection proceedings hereunder or under any Credit Document
except to the extent requested by the Required Banks (and SECTION 11.7
shall apply), and (d) not be responsible for any action taken or
omitted to be taken by it under any Credit Document 

                                 -72-
<PAGE>

or any other document or instrument referred to or provided for
therein or in connection therewith, including pursuant to its own
negligence, except for its own gross negligence or willful misconduct. 
The Agent may employ agents and attorneys-in-fact and shall not be
responsible for the negligence or misconduct of any such agents or
attorneys-in-fact selected by it with reasonable care.  Without in any
way limiting any of the foregoing, each Bank acknowledges that the
Agent shall have no greater responsibility in the operation of the
Letters of Credit than is specified in the Uniform Customs and
Practice of Documentary Credits (1993 Revision, International Chamber
of Commerce Publication No. 500).

     11.2 RELIANCE BY AGENT.  The Agent shall be entitled to rely upon
any certification, notice or other communication (including any
thereof by telephone, telex, telegram or cable) believed by it to be
genuine and correct and to have been signed or sent by or on behalf of
the proper Person or Persons, and upon advice and statements of legal
counsel (which may be counsel for the Company), independent
accountants and other experts selected by the Agent.  As to any
matters not expressly provided for by any Credit Document, the Agent
shall in all cases be fully protected in acting, or in refraining from
acting, hereunder and thereunder in accordance with instructions of
the Required Banks, and any action taken or failure to act pursuant
thereto shall be binding on all of the Banks.  

     11.3 DEFAULTS.  The Agent shall not be deemed to have knowledge
of the occurrence of a Default (other than the non-payment of
principal of or interest on Reimbursement Obligations) unless it has
received notice from a Bank or the Company specifying such Default and
stating that such notice is a "Notice of Default".  In the event that
the Agent receives such a notice of the occurrence of a Default, the
Agent shall give prompt notice thereof to the Banks (and shall give
each Bank prompt notice of each such non-payment).  The Agent shall
(subject to SECTIONS 11.7 and 12.5) take such action with respect to
such Default as shall be directed by all Banks or the Required Banks,
as appropriate, and within its rights under the Credit Documents and
at law or in equity; PROVIDED that, unless and until the Agent shall
have received such directions, the Agent may (but shall not be
obligated to) take such action, or refrain from taking such action,
permitted hereby with respect to such Default as it shall deem
advisable in the best interests of the Banks and within its rights
under the Credit Documents, at law or in equity.

     11.4 RIGHTS AS A BANK.  With respect to their Commitments, the
Letters of Credit and the Reimbursement Obligations, TCB and
NationsBank in their capacities as Banks hereunder shall have the same
rights and powers hereunder as any other Bank and may exercise the
same as though they were not acting as the Agent or the Co-Agents, and
the term "Bank" or "Banks" shall, unless the context otherwise
indicates, include the Agent and the Co-Agents in their 

                                 -73-
<PAGE>

individual capacity.  The Agent and the Co-Agents may (without having
to account therefor to any Bank) accept deposits from, lend money to
and generally engage in any kind of banking, trust, letter of credit,
agency or other business with the Company (and any of its Affiliates)
as if they were not acting as the Agent and the Co-Agents, and the
Agent and the Co-Agents may accept fees and other consideration from
the Company and its Affiliates (in addition to the fees heretofore
agreed to between the Company and the Agent or the Co-Agents) for
services in connection with this Agreement or otherwise without having
to account for the same to the Banks.

     11.5 INDEMNIFICATION.  THE BANKS AGREE TO INDEMNIFY THE AGENT (TO
THE EXTENT NOT REIMBURSED UNDER SECTION 12.3 OR 12.4, BUT WITHOUT
LIMITING THE OBLIGATIONS OF THE COMPANY UNDER SAID SECTIONS 12.3 AND
12.4), RATABLY IN ACCORDANCE WITH THEIR RESPECTIVE COMMITMENTS, FOR
ANY AND ALL LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES,
ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES OR DISBURSEMENTS OF ANY
KIND AND NATURE WHATSOEVER (INCLUDING THE CONSEQUENCES OF THE
NEGLIGENCE OF THE AGENT) WHICH MAY BE IMPOSED ON, INCURRED BY OR
ASSERTED AGAINST THE AGENT IN ANY WAY RELATING TO OR ARISING OUT OF
ANY CREDIT DOCUMENT (AS DEFINED HEREIN) OR ANY OTHER DOCUMENTS
CONTEMPLATED BY OR REFERRED TO THEREIN OR THE TRANSACTIONS CONTEM-
PLATED THEREBY (INCLUDING THE COSTS AND EXPENSES WHICH THE COMPANY IS
OBLIGATED TO PAY UNDER SECTIONS 12.3 AND 12.4 BUT EXCLUDING, UNLESS A
DEFAULT HAS OCCURRED AND IS CONTINUING, NORMAL ADMINISTRATIVE COSTS
AND EXPENSES INCIDENT TO THE PERFORMANCE OF ITS AGENCY DUTIES
HEREUNDER) OR THE ENFORCEMENT OF ANY OF THE TERMS HEREOF OR THEREOF OR
OF ANY SUCH OTHER DOCUMENTS, INCLUDING THE NEGLIGENCE OF THE AGENT;
PROVIDED THAT NO BANK SHALL BE LIABLE FOR ANY OF THE FOREGOING TO THE
EXTENT THEY ARISE FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF
THE PARTY TO BE INDEMNIFIED.  THE OBLIGATIONS OF THE BANKS UNDER THIS
SECTION 11.5 SHALL SURVIVE THE TERMINATION OF THIS AGREEMENT.

     11.6 NON-RELIANCE ON THE AGENT AND OTHER BANKS.  Each Bank agrees
that it has received current financial information with respect to the
Company and that it has, independently and without reliance on the
Agent, the Co-Agents or any other Bank and based on such documents and
information as it has deemed appropriate, made its own credit analysis
of the Company and decision to enter into this Agreement and that it
will, independently and without reliance upon the Agent, the Co-Agents
or any other Bank, and based on such documents and information as it
shall deem appropriate at the time, continue to make its own analysis
and decisions in taking or not taking action under the Credit
Documents.  The Agent and the Co-Agents shall not be required to keep
themselves informed as to the performance or observance by the Company
of any Credit Document or any other document referred to or provided
for therein or to inspect the property or books of the Company or any
other Person.  Except for notices, reports and other documents and
information expressly required to be furnished to the Banks by the
Agent and the Co-Agents under the Credit Documents, the Agent and the
Co-

                                 -74-
<PAGE>

Agents shall not have any duty or responsibility to provide any Bank
with any credit or other information concerning the affairs, financial
condition or business of the Company (or any of its Affiliates) which
may come into the possession of the Agent or either Co-Agent.

     11.7 FAILURE TO ACT.  Except for action expressly required of the
Agent under the Credit Documents, the Agent shall in all cases be
fully justified in failing or refusing to act hereunder and thereunder
unless it shall receive further assurances to its satisfaction by the
Banks of their indemnification obligations under SECTION 11.5 against
any and all liability and expense which may be incurred by it by
reason of taking or continuing to take any such action.

     11.8 RESIGNATION OR REMOVAL OF THE AGENT.  Subject to the
appointment and acceptance of a successor Agent as provided below, the
Agent may resign at any time by giving notice thereof to the Banks and
the Company, and the Agent may be removed at any time with or without
cause by the Required Banks.  Upon any such resignation or removal,
the Required Banks shall have the right to appoint a successor Agent. 
If no successor Agent shall have been so appointed by the Required
Banks and shall have accepted such appointment within 30 days after
the retiring Agent's giving of notice of resignation or the Required
Banks' removal of the retiring Agent, then the retiring Agent may, on
behalf of the Banks, appoint a successor Agent.  Any successor Agent
shall be a bank which has an office in the United States and a
combined capital and surplus of at least $250,000,000 and with its
deposits insured by the FDIC.  Upon the acceptance of any appointment
as the Agent hereunder by a successor Agent, such successor Agent
shall thereupon succeed to and become vested with all the rights,
powers, privileges and duties of the retiring Agent, and the retiring
Agent shall be discharged from its duties and obligations hereunder. 
Such successor Agent shall promptly specify its Principal Office
referred to in SECTIONS 3.1 and 5.1 by notice to the Company.  After
any retiring Agent's resignation or removal hereunder as the Agent,
the provisions of this SECTION 11 shall continue in effect for its
benefit in respect of any actions taken or omitted to be taken by it
while it was acting as the Agent.

     Section 12.  MISCELLANEOUS.

     12.1 WAIVER.  No waiver of any Default shall be a waiver of any
other Default.  No failure on the part of the Agent or any Bank to
exercise and no delay in exercising, and no course of dealing with
respect to, any right, power or privilege under any Credit Document
shall operate as a waiver thereof, nor shall any single or partial
exercise of any right, power or privilege thereunder preclude any
other or further exercise thereof or the exercise of any other right,
power or privilege.  The remedies provided in the 

                                 -75-
<PAGE>

Credit Documents are cumulative and not exclusive of any remedies
provided by law or in equity.

    12.2  NOTICES.  All notices and other communications provided for
herein (including any modifications of, or waivers or consents under,
this Agreement) shall be given or made by telex, telegraph, telecopy

telegraphed, cabled, mailed or delivered to the intended recipient at
the "Address for Notices" specified below its name on the signature
pages hereof; or, as to any party, at such other address as shall be
designated by such party in a notice to the Company and the Agent
given in accordance with this Section.  Except as otherwise provided
in this Agreement, all such communications shall be deemed to have
been duly given when transmitted by telex or telecopier, delivered to
the telegraph or cable office or personally delivered or, in the case
of a mailed notice, upon receipt, in each case given or addressed as
aforesaid.

     12.3 EXPENSES, ETC.  Whether or not any Letter of Credit is ever

Banks, the Agent and the Co-Agents for paying:  (a) the reasonable

special counsel to the Agent, in connection with (1) the preparation,
execution and delivery of the Credit Documents (including the exhibits
and schedules hereto), the issuance of the Letters of Credit hereunder
and (2) any modification, supplement or waiver of any of the terms of
any Credit Document; (b) all reasonable out-of-pocket costs and expenses
of the Banks, the Agent and the Co-Agents (including costs of
preparing an Independent Engineering Report and reasonable counsels'
fees) in connection with any Event of Default under or the enforcement
of any Credit Document; (c) all transfer, stamp, documentary or other
similar taxes, assessments or charges levied by any governmental or
revenue authority in respect of any Credit Document or any other
document referred to therein; and (d) reasonable expenses of due
diligence and syndication, and mutually agreed advertising and
marketing costs.

     12.4 INDEMNIFICATION.  THE COMPANY SHALL INDEMNIFY THE AGENT
(INCLUDING THE AGENT WHEN ACTING AS ISSUER OF THE LETTERS OF CREDIT),
THE CO-AGENTS, THE BANKS, AND EACH AFFILIATE THEREOF AND THEIR
RESPECTIVE DIRECTORS, OFFICERS, EMPLOYEES, AGENTS AND COUNSEL FROM,
AND HOLD EACH OF THEM HARMLESS AGAINST, ANY AND ALL LOSSES,
LIABILITIES, COSTS, EXPENSES, CLAIMS OR DAMAGES TO WHICH ANY OF THEM
MAY BECOME SUBJECT, REGARDLESS OF AND INCLUDING LOSSES ARISING FROM
THE NEGLIGENCE OF THE AGENT OR THE CO-AGENTS OR THE BANKS OR ANY OTHER
INDEMNITEE, (A) IN CONNECTION WITH THE EXECUTION AND DELIVERY OR
TRANSFER OF OR PAYMENT OR FAILURE TO PAY UNDER ANY LETTER OF CREDIT,
INCLUDING, WITHOUT LIMITATION, ANY CLAIMS, DAMAGES, LOSSES,
LIABILITIES, COSTS OR EXPENSES WHICH THE AGENT, SUCH CO-AGENT OR SUCH
BANK, AS THE CASE MAY BE, MAY INCUR (WHETHER INCURRED AS A RESULT OF
ITS OWN NEGLIGENCE OR OTHERWISE) BY REASON 

                                 -76-
<PAGE>

OF OR IN CONNECTION WITH THE FAILURE OF ANY OTHER BANK (WHETHER AS A
RESULT OF ITS OWN NEGLIGENCE OR OTHERWISE) TO FULFILL OR COMPLY WITH
ITS OBLIGATIONS TO THE AGENT OR SUCH BANK, AS THE CASE MAY BE,
HEREUNDER (BUT NOTHING HEREIN CONTAINED SHALL AFFECT THE RIGHTS THE
COMPANY MAY HAVE AGAINST SUCH DEFAULTING BANK); AND (B) INSOFAR AS
SUCH LOSSES, LIABILITIES, COSTS, EXPENSES, CLAIMS OR DAMAGES ARISE OUT
OF OR RESULT FROM ANY (A) ACTUAL OR PROPOSED USE BY THE COMPANY OF THE
PROCEEDS OF ANY EXTENSION OF CREDIT BY THE AGENT OR ANY BANK HEREUNDER;
(B) BREACH BY THE COMPANY OF ANY CREDIT DOCUMENT (AS DEFINED
HEREIN); (C) VIOLATION BY THE COMPANY OR ANY OF ITS SUBSIDIARIES OF
ANY LEGAL REQUIREMENT INCLUDING APPLICABLE ENVIRONMENTAL LAWS; (D) ANY
BANK'S OR THE AGENT'S OR ANY CO-AGENT'S BEING DEEMED AN OWNER OR
OPERATOR OF ANY ASSETS OF THE COMPANY OR ITS SUBSIDIARIES BY A COURT
OR OTHER REGULATORY OR ADMINISTRATIVE AGENCY OR TRIBUNAL IN CIRCUMSTANCES
IN WHICH NEITHER THE AGENT, EITHER CO-AGENT NOR ANY OF THE
BANKS IS GENERALLY OPERATING OR GENERALLY EXERCISING CONTROL OVER SUCH
ASSETS, TO THE EXTENT SUCH LOSSES, LIABILITIES, CLAIMS OR DAMAGES
ARISE OUT OF OR RESULT FROM ANY LEGAL REQUIREMENT INCLUDING APPLICABLE
ENVIRONMENTAL LAWS PERTAINING TO THE CONDITION OF SUCH ASSETS, (E)
ENVIRONMENTAL CLAIM OR (F) INVESTIGATION, LITIGATION OR OTHER PROCEEDING
(INCLUDING ANY THREATENED INVESTIGATION OR PROCEEDING) RELATING TO
ANY OF THE FOREGOING, and the Company shall reimburse the Agent,
Co-Agent, each Bank, and each Affiliate thereof and their respective
directors, officers, employees, agents and counsel, upon demand, for
any expenses (including legal fees) incurred in connection with any
such investigation or proceeding; but excluding any such losses,
liabilities, claims, damages, costs or expenses incurred by a Person
or any Affiliate thereof or their respective directors, officers,
employees, agents or counsel by reason of the gross negligence or
willful misconduct of such Person, Affiliate, director, officer,
employee, agent or counsel.  The obligation of the Company to provide
indemnification under this SECTION 12.4 for fees and expenses of
counsel shall be limited to the fees and expenses of one counsel in
each jurisdiction representing all of the Persons entitled to such
indemnification, except to the extent that, in the reasonable judgment
of any such indemnified Person, the existence of actual or potential
conflicts of interest make representation of all of such indemnified
Persons by the same counsel inappropriate; in such a case, the Person
exercising such judgment shall be indemnified for the reasonable fees
and expenses of its separate counsel to the extent provided in this
SECTION 12.4 without giving effect to the first clause of this
sentence.  Nothing in this SECTION 12.4 is intended to limit the
obligations of the Company under any other provision of this
Agreement.

     12.5 AMENDMENTS, ETC.  No amendment or waiver of any provision of
any Credit Document, nor any consent to any departure by the Company
therefrom, shall in any event be effective unless the same shall be
agreed or consented to by the Required Banks and the Company, and each
such waiver or consent shall be effective only in the specific
instance and for the specific purpose for which given; 

                                 -77-
<PAGE>


PROVIDED that no amendment, waiver or consent shall, unless in writing
and signed by each Bank affected thereby, (a) increase the Commitment
of any of the Banks or subject the Banks to any additional obligations;
(b) reduce the principal of, or interest on, any Reimbursement
Obligation, fee or other sum to be paid under any Credit Document; (c)
postpone any scheduled date fixed for any payment of principal of, or
interest on, any Reimbursement Obligation, fee or other sum to be paid
under any Credit Document; (d) change the percentage of any of the
Commitments, or of the aggregate unpaid principal amount of the
Reimbursement Obligations, or the number of Banks which shall be
required for the Banks or any of them to take any action under this
Agreement; (e) change any provision contained in SECTIONS 2.3, 5.2,
5.7, 6, 12.3 or 12.4 or this SECTION 12.5, or in the definition of
"Required Ratios".  Anything in this SECTION 12.5 to the contrary, no
amendment, waiver or consent shall be made with respect to SECTION 11
without the consent of the Agent and the Co-Agents.

     12.6 SUCCESSORS AND ASSIGNS.  (a)  This Agreement shall be
binding upon and inure to the benefit of the Company, the Agent, the
Co-Agents and the Banks and their respective successors and assigns. 
The Company may not assign or transfer any of its rights or
obligations hereunder without the prior written consent of all of the
Banks.

     (b)  Each Bank may sell participations to any Person in all or
part of its Reimbursement Obligation, or all or part of its
Commitment, in which event, without limiting the foregoing, the
provisions of SECTION 6 shall inure to the benefit of each purchaser
of a participation and the PRO RATA treatment of payments, as
described in SECTION 5.2, shall be determined as if such Bank had not
sold such participation.  In the event any Bank shall sell any
participation, (1) the Company, the Agent, the Co-Agent and the other
Banks shall continue to deal solely and directly with such selling
Bank in connection with such selling Bank's rights and obligations
under the Credit Documents (including the Applications held by such
selling Bank); (2) such Bank shall retain the sole right and
responsibility to enforce the Reimbursement Obligations, including the
right to approve any amendment, modification or waiver of any
provision of this Agreement other than amendments, modifications or
waivers with respect to (A) any fees payable hereunder to the Banks,
and (B) the amount of principal or the rate of interest payable on, or
the dates fixed for the scheduled repayment of principal of, the
Reimbursement Obligations and other sums to be paid to the Banks
hereunder, and (3) the Company agrees, to the fullest extent it may
effectively do so under applicable law, that any participant of a Bank
may exercise all rights of set-off, bankers' lien, counterclaim or
similar rights with respect to such participation as fully as if such
participant were a direct holder of Reimbursement Obligations if such
Bank has previously given notice of such participation to the Company.


                                 -78-
<PAGE>

     (c)  Each Bank may assign to one or more Banks or Eligible
Assignees all or a portion of its interests, rights and obligations
under this Agreement (including all or a portion of its Commitment and
the same portion of the related Reimbursement Obligations at the time
owing to it); PROVIDED (1) other than in the case of an assignment to
a Person at least 50% owned by the assignor Bank, or by a common
parent of both, or to another Bank, the Agent and the Company must
give their respective prior written consent, which consent will not be
unreasonably withheld; (2) the aggregate amount of the Commitment
and/or Reimbursement Obligations of the assigning Bank subject to each
such assignment (determined as of the date the Assignment Agreement
with respect to such assignment is delivered to the Agent) shall in no
event be less than $750,000 (or $75,000 in the case of an assignment
between Banks) (except for certain exceptions approved by the Company
and the Agent) and shall be in an amount that is an integral multiple
of $75,000; (3) the assigning Bank shall contemporaneously assign to
such assignee Bank or Eligible Assignee an equal percentage of the
assigning Bank's Facility B Commitment and Facility A Commitment (as
that term is defined in the Amended and Restated Revolving Credit
Agreement) and all of the assigning Bank's other rights and
obligations under the Amended and Restated Revolving Credit Agreement;
and (4) the parties to each such assignment shall execute and deliver
to the Agent, for its acceptance and recording in its records, an
Assignment Agreement with blanks appropriately completed, together
with the Applications subject to such assignment and a processing and
recordation fee of $2,000 (for which the Company shall have no liability
except in the case of assignments required by the Company pursuant
to SECTION 6.1 or 6.2, in which case such fee shall be paid by the
Company).  Upon such execution, delivery, acceptance and recording,
from and after the effective date specified in each Assignment
Agreement, (A) the assignee thereunder shall be a party hereto and, to
the extent provided in such Assignment Agreement, have the rights and
obligations of a Bank hereunder, and (B) the Bank making such
assignment shall, to the extent provided in such assignment, be
released from its obligations under this Agreement (and, in the case
of an Assignment Agreement covering all or the remaining portion of an
assigning Bank's rights and obligations under this Agreement, such
Bank shall cease to be a party hereto).

     (d)  By executing and delivering an Assignment Agreement, the
Bank assignor thereunder and the assignee thereunder confirm to and
agree with each other and the other parties hereto as follows:  (1)
other than the representation and warranty that it is the legal and
beneficial owner of the interest being assigned thereby, such assignor
Bank makes no representation or warranty and assumes no responsibility
with respect to any statements, warranties or representations made in
or in connection with any Credit Document or the execution, legality,
validity, enforceability, genuineness, sufficiency or value of any
Credit Document; (2) such assignor Bank makes no representation or
warranty and assumes no responsibility with respect to the financial
condition of the Company or the 
                                 -79-
<PAGE>

performance or observance by the Company of any of its obligations
under any Credit Document; (3) such assignee confirms that it has
received a copy of this Agreement, together with copies of the
financial statements of the Company previously delivered in accordance
herewith and such other documents and information as it has deemed
appropriate to make its own credit analysis and decision to enter into
such Assignment Agreement; (4) such assignee will, independently and
without reliance upon the Agent, such assignor Bank or any other Bank
and based on such documents and information as it shall deem appropriate
at the time, continue to make its own credit decisions in taking
or not taking action under the Credit Documents; (5) such assignee
appoints and authorizes the Agent to take such action as agent on its
behalf and to exercise such powers under the Credit Documents as are
delegated to the Agent by the terms hereof, together with such powers
as are reasonably incidental thereto, and (6) such assignee agrees
that it will perform in accordance with their terms all obligations
that by the terms of the Credit Documents are required to be performed
by it as a Bank.

     (e)  The Agent shall maintain at its office a copy of each
Assignment Agreement delivered to it and a record of the names and
addresses of the Banks and the Commitment of, and principal amount of
the Reimbursement Obligations owing to, each Bank from time to time. 
The entries in such record shall be conclusive, in the absence of
manifest error, and the Company, the Agent and the Banks may treat
each Person the name of which is recorded therein as a Bank hereunder
for all purposes of the Credit Documents.  Such records shall be
available for inspection by the Company or any Bank at any reasonable
time and from time to time upon reasonable prior notice.

     (f)  Upon its receipt of an Assignment Agreement executed by an
assigning Bank and the assignee thereunder together with the
Application subject to such assignment, the written consent to such
assignment and the fee payable in respect thereto, the Agent shall, if
such Assignment Agreement has been completed with blanks appropriately
filled, (1) accept such Assignment Agreement; (2) record the
information contained therein in its records, and (3) give prompt
notice thereof to the Company.  

     (g)  Any Bank may, in connection with any assignment or
participation or proposed assignment or participation pursuant to this
Section, disclose to the assignee or participant or proposed assignee
or participant, any information relating to the Company furnished to
such Bank by or on behalf of the Company.

     (h)  Any assignment by a Bank pursuant to this SECTION 12.6 shall
not result in any single Bank holding in excess of 25% of the
Aggregate Commitment at any one time.

                                 -80-

     (i)  Notwithstanding any other provision of this SECTION 12.6,
TCB and its Affiliates may not assign their rights hereunder unless,
after giving effect to such assignment, TCB and its Affiliates would
have an aggregate Commitment Percentage of at least 10%.

     (j)  Notwithstanding anything herein to the contrary, each Bank
may pledge and assign all or any portion of its rights and interests
under the Credit Documents to any Federal Reserve Bank.

     12.7 SURVIVAL; TERM; REINSTATEMENT.  In addition to the other
provisions of this Agreement expressly stated to survive the
termination of this Agreement, the obligations of the Company under
SECTIONS 6, 12.3 and 12.4 and the last sentence of this SECTION 12.7
and the obligations of the Banks under SECTION 12.8 shall survive the
termination of this Agreement.  The term of this Agreement shall be
until (a) the full and final payment of all Reimbursement Obligations,
(b) the expiry of all Letters of Credit, (c) the termination of all
Commitments and (d) the payment of all amounts due under the Credit
Documents.  The Company agrees that if at any time all or any part of
any payment previously applied by any Bank to any Reimbursement
Obligation or other sum hereunder is or must be returned by or
recovered from such Bank for any reason (including the order of any
bankruptcy court), the Credit Documents shall automatically be
reinstated to the same effect as if the prior application had not been
made, and the Company hereby agrees to indemnify such Bank against,
and to save and hold such Bank harmless from, any required return by
or recovery from such Bank of any such payment because of its being
deemed preferential under applicable Legal Requirements, or for any
other reason.  

     12.8 LIMITATION OF INTEREST.  The parties to this Agreement
intend to strictly comply with all applicable laws, including
applicable usury laws.  Accordingly, the provisions of this Section
shall govern and control over every other provision of any Credit
Document which conflicts or is inconsistent with this Section, even if
such provision declares that it controls.  As used in this SECTION
12.8, the term "interest" includes the aggregate of all charges, fees,
benefits or other compensation which constitute interest under
applicable law; PROVIDED that, to the maximum extent permitted by
applicable law, (a) any non-principal payment shall be characterized
as an expense or as compensation for something other than the use,
forbearance or detention of money, and not as interest and (b) all
interest at any time contracted for, taken, reserved, retained,
charged or received shall be amortized, prorated, allocated and
spread, in equal parts during the full term of this Agreement and the
Commitments.  In no event shall the Company or any other Person be
obligated to pay, or the Agent or any Bank have any right or privilege
to reserve, receive or retain, (x) any interest in excess of the
maximum amount of nonusurious interest permitted under the laws of the
State of Texas or the applicable laws (if any) of the United States or
of any other state 

                                 -81-
<PAGE>

or (y) total interest in excess of the amount which the Agent or such
Bank could lawfully have contracted for, taken, reserved, received,
retained or charged had the interest been calculated for the full term
of this Agreement at the Highest Lawful Rate.  On each day, if any,
that the interest rate (the "STATED RATE") called for under any Credit
Document exceeds the Highest Lawful Rate, the rate at which interest
shall accrue shall automatically be fixed by operation of this
sentence at the Highest Lawful Rate for that day, and shall remain
fixed at the Highest Lawful Rate for each day thereafter until the
total amount of interest accrued equals the total amount of interest
which would have accrued if there were no such ceiling rate as is
imposed by this sentence.  Thereafter, interest shall accrue at the
Stated Rate unless and until the Stated Rate again exceeds the Highest
Lawful Rate when the provisions of the immediately preceding sentence
shall again automatically operate to limit the interest accrual rate. 
The daily interest rates to be used in calculating interest at the
Highest Lawful Rate shall be determined by dividing the applicable
Highest Lawful Rate per annum by the number of days in the calendar
year for which such calculation is being made.  None of the terms and
provisions contained in any Credit Document which directly or
indirectly relate to interest shall ever be construed without
reference to this Section, or be construed to create a contract to pay
for the use, forbearance or detention of money at an interest rate in
excess of the Highest Lawful Rate.  If the term of this Agreement is
shortened by reason of acceleration of maturity as a result of any
Default or by any other cause, or by reason of any required or
permitted prepayment, and if for that (or any other) reason the Agent
or any Bank at any time, including the stated maturity, is owed or
receives (and/or has received) interest in excess of interest
calculated at the Highest Lawful Rate, then and in any such event all
of any such excess interest shall be canceled automatically as of the
date of such acceleration, prepayment or other event which produces
the excess, and, if such excess interest has been paid to the Agent or
such Bank, it shall be credited PRO TANTO against the then-outstanding
principal balance of the Company's obligations to the Agent or such
Bank, effective as of the date or dates when the event occurs which
causes it to be excess interest, until such excess is exhausted or all
of such principal has been fully paid and satisfied, whichever occurs
first, and any remaining balance of such excess shall be promptly
refunded to its payor.

     12.9 CAPTIONS.  Captions and section headings appearing herein
are included solely for convenience of reference and are not intended

     12.10     COUNTERPARTS.  Each Credit Document may be executed in

EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER
HAVE TO THE LAYING OF THE VENUE OF ANY SUCH PROCEEDING BROUGHT IN SUCH
A COURT AND ANY CLAIM THAT ANY SUCH PROCEEDING BROUGHT IN SUCH A COURT
HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.

     12.12     SEVERABILITY.  Whenever possible, each provision of the
Credit Documents shall be interpreted in such manner as to be
effective and valid under applicable law.  If any provision of any
Credit Document shall be invalid, illegal or unenforceable in any
respect under any applicable law, the validity, legality and
enforceability of the remaining provisions of such Credit Document
shall not be affected or impaired thereby.

     12.13     CHAPTER 15 NOT APPLICABLE.  Chapter 15 of the Texas
Credit Code shall not apply to any Credit Document or to any
Commitment or Letter of Credit or Application or Reimbursement
Obligation, nor shall any Credit Document be governed by or be subject
to the provisions of such Chapter 15 in any manner whatsoever.
