          Effective August 1, 1997, the Company entered into an amended and 
restated credit agreement (the "Credit Agreement").  The Credit Agreement 
provides for an unsecured $250,000,000 revolving/term credit facility which 
will be fully revolving until July 1, 2000, after which the balance will 
be due in eight quarterly term loan installments, commencing October 31, 2000.
The amount that may be borrowed under the Credit Agreement may not exceed 
a borrowing base which is composed of both domestic and Thai properties less,
in certain circumstances, the present value of interest payments on a portion
of certain subordinated indebtedness, including the 2007 Notes.  
The domestic borrowing base is determined semi-annually by the lenders 
in accordance with the Credit Agreement, based primarily on the discounted 
present value of future net revenues from the Company's domestic oil and gas 
reserves.  The portion of the borrowing base which is composed of properties
located in the Kingdom of Thailand is also determined semi-annually, but may, 
at the lenders discretion, be redetermined once more during each semi-annual 
period. The value of this portion of the borrowing base is determined by the
lenders applying their usual and customary criteria for 
oil and gas evaluation.  As of August 1, 1997, the Company's total borrowing 
base, including both domestic and Thai properties, exceeded $250,000,000.  
The Credit Agreement is governed by various financial and other covenants, 
including requirements to maintain positive working capital (excluding 
current maturities of debt) and a fixed charge coverage ratio, and 
limitations on indebtedness, creation of liens, the prepayment of

subordinated debt, the payment of dividends, mergers and consolidations, 
investments and asset dispositions.  In addition, the Company is prohibited
from pledging borrowing base properties as security for other debt.  
Borrowings under the Credit Agreement currently bear interest at  a base 
(prime) rate or LIBOR plus 5/8%, at the Company's option.  A commitment fee 
on the unborrowed amount under the Credit Agreement is also charged.  The 
commitment fee is currently 0.25% per annum on the unborrowed amount under 
the Credit Agreement that is designated as "active" and 0.10% per annum 
on the unborrowed amount under the Credit Agreement that is designated as 
"inactive."  Of the $250,000,000 that is currently available under the 
Credit Agreement (subject to borrowing base limitations), $125,000,000 
is designated as "active" and $125,000,000 is designated as "inactive." 

          On May 22, 1997, the Company issued $100,000,000 of 8 3/4%
Senior Subordinated Notes due 2007 (the "2007 Notes").  The proceeds from
the issuance of the 2007 Notes were used to repay amounts outstanding under
the Company's bank revolving credit agreement, and to purchase short-term 
cash investments.  The 2007 Notes bear interest at a rate of 8 3/4%, 
payable semi-annually in arrears on May 15 and November 15 of each year, 
commencing November 15, 1997.  The 2007 Notes are general unsecured senior 
subordinated obligations of the Company and are subordinated in
right of payment to the Company's senior indebtedness, which currently 
includes its obligations under its bank revolving credit agreement and its
unsecured credit lines, but are senior in right of payment to the Company's 
subordinated indebtedness, which currently includes the 2006 Notes
and the 2004 Notes.  The Company, at its option, may redeem the 2007 Notes 
in whole or in part, at any time on or after May 15, 2002, at a redemption 
price of 104.375% of their principal value and decreasing percentages 
thereafter.  No sinking fund payments are required on the 2007 Notes.  The
2007 Notes are redeemable at the option of any holder, upon the occurrence 
of a change of control (as defined in the indenture governing the 2007 Notes),
at 101% of their principal amount.  The indenture governing the 2007 Notes 
also imposes certain covenants on the Company (as more fully described therein)
that are customary for senior subordinated indebtedness generally,
including covenants limiting: incurrence of indebtedness, including senior
indebtedness; restricted payments; the issuance and sales of restricted 
subsidiary capital stock; transactions with affiliates; liens; disposition 
of proceeds of asset sales; non-guarantor restricted subsidiaries; dividends 
and other payment restrictions affecting restricted subsidiaries; and mergers,
consolidations and the sale of assets.

          Refer to Note 3 of the Notes to Consolidated Financial
Statements included in the Company's latest annual report for a further
discussion of the bank revolving credit agreement, the 5 1/2% 
Convertible Subordinated Notes due 2004 (the "2004 Notes") and the 5 1/2% 
Convertible Subordinated Notes due 2006 (the "2006 Notes").

                    Management's Discussion and Analysis of
                 Financial Condition and Results of Operations

          This discussion should be read in conjunction
with Management's Discussion and Analysis of Financial
Condition and Results of Operations included in the
Company's annual report on Form 10-K for the year
ended December 31, 1996.  Certain statements contained herein are "Forward
Looking Statements" and are thus prospective.  As further discussed in the
Company's annual report on Form 10-K, such forward-looking statements are
subject to risks, uncertainties and other factors which could cause actual
results to differ materially from future results expressed or implied by
such forward-looking statements.
                                                   

RESULTS OF OPERATIONS --

INCOME AND REVENUE DATA

NET INCOME 
               
          The Company reported net income for the
second quarter of 1997 of $9,174,000 or $0.27 per share
($0.26 on a fully diluted basis) compared to net income
for the second quarter of 1996 of $8,116,000 or $0.24
per share ($0.23 on a fully diluted basis).  For the
first six months of 1997, the Company reported net
income of $21,992,000 or $0.64 per share ($0.62 on a fully diluted 
basis) compared to net income for the first six months
of 1996 of $14,381,000 or $0.42 per share (on both a primary and a 
fully diluted basis).  The Company recorded an extraordinary loss 
during the second quarter of 1996 of $821,000, or $0.02 per share 
related to early retirement of the Company's 2005 Debentures with 
the proceeds from the Company's issuance of its 2006 Notes on 
June 18, 1996.  Earnings per share are based on the
weighted average number of common and common
equivalent shares outstanding for the second quarter and 
first six months of 1997 of 34,153,000 and
34,165,000, respectively, compared to 33,976,000 and
33,905,000, respectively, for the second quarter and 
first six months of 1996.  The increases in the
weighted average number of common and common equivalent
shares outstanding for the 1997 periods, compared to  
the 1996 periods, resulted primarily from the issuance of 
shares of common stock  upon the exercise of stock options 
pursuant to the Company's stock option plans.  Earnings per share
computations on a fully diluted basis in the 1997 periods 
primarily reflect additional shares of common stock issuable 
upon the assumed conversion of the Company's 2004 Notes 
(the only convertible securities of the Company that were
dilutive during any of the periods presented) and the
elimination of related interest requirements, as adjusted for
applicable federal income taxes.  The weighted average
number of shares of common and common equivalent shares
outstanding on a fully diluted basis for the second 
quarter and first six months of 1997 were 38,054,000 and
38,058,000, respectively, compared to 37,899,000 and
37,821,000 respectively, for the second quarter and 
first six months of 1996.  Earnings applicable to common stock, 
assuming full dilution and, with respect to the 1996 periods, 
after giving effect to an extraordinary loss of $821,000, 
for the second quarter and first six months of
1997 were $9,945,000 and $23,533,000, respectively, 
compared to $8,887,000 and $15,923,000, respectively, for 
the second quarter and first six months of 1996.

   REVENUES
      
          TOTAL REVENUES  

          The Company's total revenues for the second
quarter of 1997 were $76,740,000, an increase of
approximately 49% compared to total revenues of
$51,543,000 for the second quarter of 1996. The 
Company's total revenues for the first six
months of 1997 were $138,054,000, an increase of approximately 39% 
compared to total revenues of $99,595,000 for the first six 
months of 1996. The increase in the Company's total revenues for 
the second quarter and first six months of 1997, compared to the 
second quarter and first six months of 1996, resulted primarily 
from increases in the the Company's natural gas and liquid hydrocarbon 
(including crude oil, condensate and natural gas liquid ("NGL")) 
production volumes, that were only partially offset by decreases in
the average price that the Company received for such production.  
In addition, the total revenues for the second quarter and first six 
months of 1997 were positively affected by a $1,600,000 non-recurring 
gain recorded in connection with the sale of certain excess equipment, 
while the Company's total revenues for the first six months of of 1996 
were adversely affected by a $165,000 loss resulting from the sale of a 
non-strategic property.
     
          OIL AND GAS REVENUES.  

          The following table reflects an analysis 
of differences in the Company's oil and gas revenues (expressed
in thousands of dollars) between the second quarter and

        NATURAL GAS PRICES.  Prices per thousand cubic feet ("Mcf") that 
the Company received for its natural gas production during the second 
quarter of 1997 averaged $2.14 per Mcf, a decrease of approximately 
7% from an average price of $2.31 per Mcf that the Company received for its
production during the second quarter of 1996.  Prices that the 
Company received for its natural gas production during
the first six months of 1997 averaged $2.34 per Mcf, a decrease 
of approximately 1% from an average price of $2.36 per Mcf that the 
Company received for its domestic natural gas production during the
first six months of 1996.   
     
        DOMESTIC PRICES.  prices that the Company received for its 
domestic natural gas 
production during the second quarter of 1997 averaged $2.15 per Mcf, 
a decrease of approximately 7% from an average price of $2.31 per Mcf 
that the Company received for its domestic natural gas production 
during the second quarter of 1996.  Prices that the 
Company received for its domestic natural gas production during
the first six months of 1997 averaged $2.41 per Mcf, an increase 
of approximately 2% from an average price of $2.36 per Mcf that the 
Company received for its domestic natural gas production during the
first six months of 1996.   
   
        THAILAND PRICES.  The Company's Tantawan Field located in the 
Kingdom of Thailand commenced production of natural gas and liquid 
hydrocarbons in February 
1997.  During the second quarter of 1997, the price that the Company 
received under its long term gas sales contract for natural gas production 
from the Tantawan Field averaged approximately 54 Thai Baht per Mcf.  
At the then prevailing currency exchange rates of approximately 25.5 Baht 
to the dollar, this equaled approximately $2.12 per Mcf.  In early July 
1997, the government of the Kingdom of Thailand announced that the value 
of the Baht would be set against the dollar and other currencies 
under a "managed float" arrangement.  Since that time, the value of the Baht 
has declined.  As of July 31, 1997, the prevailing currency exchange rate
was approximately 32 Baht to the dollar.  The Company cannot predict what
the Baht to dollar exchange rate may be in the future.  Moreover, it is 
anticipated that this exchange rate will remain volatile.
            
         NATURAL GAS PRODUCTION.  The Company's natural gas production 
during the second quarter of 1997 averaged 216.8 million cubic feet 
("MMcf") per day, an increase of approximately 103% from an average of 
106.6 MMcf per day that the Company produced during the second
quarter of 1996.  The Company's natural gas production 
during the first six months of 1997 averaged 173.5 MMcf 
per day, an increase of approximately 59% from an
average of 108.9 MMcf per day that the Company
produced during the first six months of 1996. 

         DOMESTIC PRODUCTION.  The Company's domestic natural gas 
production during the second quarter of 1997 averaged 177.8 MMcf per 
day, an increase of approximately 
67% from an average of 106.6 MMcf per day that the Company produced 
during the second quarter of 1996.  The Company's domestic natural gas 
production during the first six months of 1997 averaged 145.1 MMcf 
per day, an increase of approximately 33% from an average of 108.9 MMcf 
per day that the Company produced during the first six months of 1996. 
The increase in the Company's natural gas production during 
the second quarter and first six months of 1997, compared to 
the second quarter and first six months of 1996, was related in large 
measure to production from the Company's East Cameron Block 334 "E" platform, 
which commenced production in April 1997, and, to a lesser extent, the 
results of successful drilling in the Company's Lopeno Field in South Texas 
and its Eugene Island Block 261 field, that

was only partially offset by the anticipated decline from certain of the 
Company's properties.  As of August 1, 1997, the Company was not a party 
to any future natural gas sales contracts.

         THAILAND PRODUCTION.  The Company commenced production from 
its Tantawan Field early in 
February 1997.  Following a field startup phase which ended on 
March 15, 1997, production from the Tantawan Field stabilized.  During 
the second quarter of 1997, the Company's share of natural gas
production from the Tantawan Field averaged approximately 39 MMcf per day.
The Company anticipates that production will remain at approximately this 
level until October 1997, when, in accordance with the long term gas sales
contract with the Petroleum Authority of Thailand for the Tantawan Field, 
natural gas production from the field is anticipated to increase to 
approximately 45 MMcf per day (net to the Company's working interest).

         CRUDE OIL AND CONDENSATE PRICES.  Prices received by the Company for 
its crude oil and condensate production during the second quarter of 1997
averaged $18.35 per barrel, a decrease of approximately 19% from 
the average price of $22.58 per barrel that the Company 
received during the second quarter of 1996.  Prices that the
Company received for its crude oil and condensate production during 
the first six months of 1997 averaged $20.14 per barrel, a decrease of 
approximately 5% from an average price of $21.14 per barrel 
that the Company received during the first six months of 1996.  

         DOMESTIC PRICES.  Prices received by the Company for its domestic 
 crude oil and condensate production during the second quarter of 1997
averaged $18.54 per barrel, a decrease of approximately 18% from 
the average price of $22.58 per barrel that the Company 
received during the second quarter of 1996.  Prices that the
Company received for its domestic crude oil and condensate production during 
the first six months of 1997 averaged $20.40 per barrel, a decrease of 
approximately 4% from an average price of $21.14 per barrel 
that the Company received during the first six months of 1996.  

         THAILAND PRICES.  Since the inception of production from the 
Tantawan Field, crude 
oil and condensate has been stored in a Floating Production, Storage and 
Offloading System (the "FPSO") until an economic quantity was accumulated 
for offloading and sale.  The first such sale of crude oil and condensate 
from the Tantawan Field occurred in July 1997.  Prices that the Company 
recorded for its crude oil and condensate production stored on the FPSO 
for the second quarter and first six months of 1997, were $17.26 and 
$18.15, respectively.  Prices that the Company currently expects to receive 
for such production (and in fact did receive for its July 1997 sale) are 
based on world benchmark prices, which are denominated in dollars.

         CRUDE OIL AND CONDENSATE PRODUCTION.  The Company's crude oil and
condensate production during the second quarter of 1997 averaged 16,457 
barrels per day, an increase of approximately 23% from an average of 
12,605 barrels per day during the second quarter of 1996.  The Company's
crude oil and condensate production during the first six months of 1997
averaged 15,273 barrels per day, an increase of approximately 25% from 
an average of 12,247 barrels per day during the first six months of 1996.

         DOMESTIC PRODUCTION.  The Company's domestic crude oil and
condensate production during the second quarter of 1997 averaged 14,065 
barrels per day, an increase of approximately 12% from an average of 
12,605 barrels per day during the second quarter of 1996.  The Company's
domestic crude oil and condensate production during the first six months 
of 1997 averaged 13,531 barrels per day, an increase of approximately 25% 
from an average of 12,247 barrels per day during the first six months 
of 1996.  The increase in the Company's domestic crude oil and condensate
production during the second quarter and first six months of 1997, 
compared to the second quarter and first six months of 1996, resulted 
primarily from the success of the Company's ongoing development drilling
and workover program in the offshore and onshore Gulf of Mexico regions.

         THAILAND PRODUCTION.  The Company commenced production from its
Tantawan Field early in February 1997.  Following a field startup phase
which ended on March 15, 1997, production from the Tantawan Field 
stabilized.  During the second quarter of 1997, the Company's share of
crude oil and condensate production production from the Tantawan Field
averaged approximately 2,392 barrels per day.

          NGL PRODUCTION AND "OTHER" NET REVENUE ITEMS.  The Company's 
oil and gas revenues, and total liquid hydrocarbon 
production volumes reflect the production and sale of NGL by the Company.  
In addition, the Company's oil and gas revenues for the second quarter 
and first six months of 1997 and 1996 also reflect adjustments for 
various miscellaneous items of a non-recurring nature.  

          Liquid products are often extracted from its natural gas streams 
and sold separately as NGL.  All of the Company's NGL production comes 
from its domestic operations.  The prices that the Company typically 
receives for its NGL production is related to crude oil prices.  However, 
because NGL is extracted from liquid rich natural gas, the Company's NGL 
production volumes correlate most closely with increases (or decreases) 
from certain of the Company's natural gas fields.  Natural gas production
from the Company's East Cameron Block 334 "E" platform is considered
to be relatively rich in NGL.

          The Company's NGL and "other" net revenues for the second quarter 
and first six months of 1997 increased $2,336,000 and $2,038,000, 
from the second quarter and first six months of 1996, respectively. 
The increase in the Company's NGL and "other" net revenues for the second 
quarter and first six months of 1997, compared to the second quarter 
and first six months of 1996, was primarily related to an increase in 
the Company's NGL production from the Company's East Cameron 334 "E" platform, 
that was only partially offset by a decrease in the average price that the 
Company received for its NGL production. 

          TOTAL LIQUID HYDROCARBON PRODUCTION.  The Company's average 
liquid hydrocarbon (including crude oil, condensate and NGL) production 
during the second quarter of 1997 was 20,997 barrels per day, an increase of 
approximately 39% from an average liquid hydrocarbon production 
of 15,077 barrels per day during the second quarter of 1996.  
The Company's average liquid hydrocarbon production during the first six 
months of 1997 was 18,122 barrels per day, an increase of approximately
25% from an average liquid hydrocarbon production
of 14,475 barrels per day during the first six months of 1996.

OPERATING COSTS AND EXPENSES

         LEASE OPERATING EXPENSES

         Lease operating expenses for the second quarter of 
1997 were $16,191,000, an increase of approximately 76% from lease
operating expenses of $9,205,000 for the second quarter of 1996.  
Lease operating expenses for the first six months of 1997 were 
$28,488,000, an increase of approximately 58% from lease operating 
expenses of $18,080,000 for the first six months of 1996. 
The increases in lease operating expenses for the second quarter 
and first six months of 1997, compared to the second quarter 
and first six months of 1996, resulted primarily from 
expenses related to the leasing of equipment (principally the FPSO);
increased operating activity by the Company and its industry partners; 
and increased costs to the Company (and the entire offshore oil
industry) due to a shortage of qualified offshore
service contractors and equipment, which has permitted such contractors 
to increase the costs of their services.
   
         GENERAL AND ADMINISTRATIVE EXPENSES
    
         General and administrative expenses for the second 
quarter of 1997 were $5,121,000, an increase of approximately 17% from
general and administrative expenses of $4,383,000 for the second
quarter of 1996.  General and administrative expenses for 
the first six months of 1997 were $10,957,000, an increase of approximately 
12% from general and administrative expenses of $9,804,000 for the first 
six months of 1996.  The increases in general and administrative expenses
for the second quarter and first six months of 1997, compared with the 
second quarter and first six months of 1996,
were related to, among other things, an increase in the size of the Company's 
work force and leased office space in the United States and Bangkok, 
Thailand and normal salary and concomitant benefit expense adjustments that
were partially offset by decreases in miscellaneous general and administrative
expense items.
   
         EXPLORATION EXPENSES
   
         Exploration expenses consist primarily of delay rentals and
geological and geophysical costs which are expensed as incurred.
Exploration expenses for the second quarter of 1997 were $4,053,000, an 
increase of approximately 1% from exploration expenses of $3,996,000 
for the second quarter of 1996.  The increase in exploration expenses
for the second quarter of 1997, compared to the second quarter of 1996,
resulted primarily from increased geophysical activity by the Company in 
the Gulf of Mexico and an increase in delay rentals, which was not entirely 
offset by a decrease in geophysical activity in other areas in which the 
Company is currently conducting geophysical operations.  Exploration 
expenses for the first six months of 1997 were $5,953,000, a decrease of 
approximately 24% from exploration expenses of $7,876,000 for the first 
six months of 1996.  The decrease in exploration expenses for the first
six months of 1997, compared to the first six months of 1996, resulted
primarily from a decrease in expenses resulting from the completion of 
a 3-D seismic survey by the Company on its leases in South Louisiana and 
East Texas in the first six months of 1996, which was partially offset
by increased expenses resulting from geophysical activity by the Company 
in the Gulf of Mexico; and also by increased delay rental payments.

         DRY HOLE AND IMPAIRMENT EXPENSES
   
         Dry hole and impairment expenses relate to costs of 
unsuccessful wells drilled, along with impairments due to decreases in
expected reserves from producing wells.  The Company's dry 
hole and impairment expenses for the second quarter of 1997 were 
$4,086,000, an increase of approximately 59% from dry hole and 
impairment expenses of $2,568,000 for the second quarter of 1996.  The
Company's dry hole and impairment expenses for the first six months of
1997 were $5,007,000, a decrease of approximately 2% from dry hole and
impairment expenses of $5,118,000 for the first six months of 1996.
   
         DEPRECIATION, DEPLETION AND AMORTIZATION EXPENSES
   
         The Company accounts for its oil and gas activities using the 
successful efforts method of accounting.  Under the successful
efforts method, lease acquisition costs and all development costs are
capitalized.  Unproved properties are reviewed whenever events or 
changes in circumstances indicate that the carrying amount of such asset
may not be recoverable.  Unproved properties are reviewed quarterly, with
any such impairment charged to expense in the period.  Exploratory drilling 
costs are capitalized until the results are determined.  If proved 
reserves are not discovered, the exploratory drilling costs are
expensed.  Other exploratory costs are expensed as incurred.

         The provision for depreciation, depletion and amortization 
("DD&A") is based on the capitalized costs, as determined in the preceding 
paragraph, plus future costs to abandon offshore wells and platforms, and
is determined on a cost center by cost center (generally, a field by field)
basis using the units of production method.  The Company's DD&A expense 
for the second quarter of
1997 was $28,457,000, an increase of approximately 80% from DD&A 
expense of $15,793,000 for the second quarter of 1996.  The Company's 
DD&A expense for the first six months of 1997 was $46,877,000, an 
increase of approximately 49% from DD&A expense of $31,506,000 for the 
first six months of 1996.  The increases in DD&A expense for the second
quarter and first six months of 1997, compared to the second 
quarter and first six months of 1996, resulted 
primarily from increased production of oil and gas from the Company's  
properties and, to a much lesser extent, a slight increase in the Company's 
composite DD&A rate.  The composite DD&A rate for all of the 
Company's producing fields for the second quarter of 1997 was $0.90
per equivalent Mcf ($5.38 per equivalent barrel), an increase of 
approximately 3% from a composite DD&A rate of $0.87 per equivalent 
Mcf ($5.22 per equivalent barrel) for the second quarter of 1996.  

         The composite DD&A rate for all of the Company's producing fields for
the first six months of 1997 was $0.90 per equivalent Mcf ($5.41 per equivalent
barrel), an increase of approximately 3% from a composite DD&A rate of $0.87 
per equivalent Mcf ($5.24 per equivalent barrel) for the first six 
months of 1996.  The increase in the composite DD&A rate for all of the 
Company's producing fields for the second quarter and the first six months 
of 1997, compared to the second quarter and 
first six months of 1996, resulted primarily from an increased percentage 
of the Company's production coming from certain of the Company's fields 
that have DD&A rates that are higher than the Company's recent historical 
composite rate and a corresponding decrease in the percentage of the 
Company's production coming from fields that have DD&A rates that are 
lower than the

Company's recent historical composite DD&A rate.  The 
Company produced 31,197,000 equivalent Mcf (5,200,000 equivalent
barrels) during the second quarter of 1997, an increase of approximately
74% from the 17,932,000 equivalent Mcf (2,989,000 equivalent barrels)
produced by the Company during the second quarter of 1996.  
The Company produced 51,178,000 equivalent Mcf (8,530,000 
equivalent barrels) during the first six months of 1997, an increase of
approximately 44% from the 35,628,000 equivalent Mcf (5,938,000 equivalent
barrels) produced by the Company during the first six months of 1996.
   
INTEREST 
   
         INTEREST CHARGES

         The Company incurred interest charges for the 
second quarter of 1997 of $5,536,000, an increase of approximately 75% 
from interest charges of $3,172,000 for the second quarter of 1996.  
Interest charges incurred by the Company for the first six months 
of 1997 were $9,831,000, an increase of approximately 59% from interest 
charges of $6,184,000 for the first six months of 1996.  
The increases in interest charges for the second quarter and first six 
months of 1997, compared to the second quarter and first six months of 1996, 
resulted primarily from an increase in the average amount of the Company's
outstanding debt and, to a lesser extent, increased amortization and debt
issuance expenses resulting from the issuance of the 2006 Notes, that were
partially offset by lower average interest rate levels on the debt 
outstanding (resulting primarily from the retirement of the 8% Debentures
and the issuance of the 2006 Notes that bear interest at a 5-1/2% annual
interest rate).

         CAPITALIZED INTEREST EXPENSE

         Capitalized interest expense for 
the second quarter of 1997 was $760,000, a decrease of approximately 
24% from capitalized interest expense of $1,004,000 for the first quarter 
of 1996.  The decrease in capitalized interest expense for the second 
quarter of 1997, compared to the second quarter of 1996, resulted 
primarily the cessation of the requirement to capitalize interest expense 
attributable to capital expenditures on properties once production 
commences from such properties.  A substantial percentage of the 
Company's capitalized interest
expense during 1996 and most of the first quarter of 1997 resulted
from capitalization of interest related to capital expenditures for the 
development of the Tantawan Field (which commenced production in early
February 1997) and the East Cameron Block 334 "E" platform field (which 
commenced production in early April 1997).  Capitalized interest expense 
for the first six months of 1997 was $2,630,000, an increase of 
approximately 44% from capitalized interest expense of $1,830,000 for the 
first six months of 1996.  For the reasons enumerated above, the increase 
in capitalized interest 
expense for the first six months of 1997, compared to the first six months 
of 1996, resulted primarily from the requirement to capitalize interest 
expense attributable to capital expenditures on non-producing properties, 
principally capital expenditures related to the Company's development of 
the Tantawan Field and the East Cameron Block 334 "E" platform during the
first quarter of 1997, which substantially exceeded the Company's capital
expenditures on non-producing properties (principally the Tantawan Field) 
during the first six months of 1996.

         As of August 1, 1997, the Company was a party to an interest rate
swap agreement.  The swap agreement, which terminates on March 10, 1998,
effectively changes the interest rate that the Company would pay on 
$5,000,000 of debt from a market based variable rate to a fixed rate of 7.2%.  

INCOME TAX EXPENSE
   
         Income tax expense for the second quarter of 1997 was 
$4,955,000, an increase of approximately 7% from income tax expense
of $4,647,000 for the second quarter of 1996.  Income tax expense 
for the first six months of 1997 was $11,708,000, an increase of 
approximately 50% from income tax expense of $7,794,000 for the 
first six months of 1996.  The increase in income tax expense for the
second quarter and first six months of 1997, compared to the second
quarter and first six months of 1996, resulted primarily
from increased pre-tax income.

LIQUIDITY AND CAPITAL RESOURCES --

CASH FLOWS
 
          The Company's Condensed Consolidated Statement of Cash Flows for 
the six months ended June 30, 1997, reflects net cash provided by operating 
activities of $73,807,000 (including an income tax refund of $7,037,000 
which was partially offset by a payment of estimated income taxes of 
$4,500,000).  In addition to net cash provided by operating
activities, the Company received net proceeds of $97,270,000 from the 
issuance of the 2007 Notes on May 22, 1997, $958,000 from the exercise 
of stock options and $100,000 from the sale of certain non-strategic 
properties.  

        During the first six months of 1997, the Company invested $112,617,000 
of such cash flow in capital projects, repaid a net $8,000,000 
under its revolving credit facility and paid $2,002,000 ($0.03 per share 
for each of the first two quarters of 1997) in cash dividends to 
holders of the Company's common stock.  Of the $112,617,000 
invested in capital projects, $56,961,000 was applicable to 1996 capital 
projects and $55,656,000 was applicable to 1997
capital projects.  As of June 30, 1997, the Company's cash and cash 
investments were $23,505,000 and its long-term debt stood at $338,205,000.

FUTURE CAPITAL REQUIREMENTS

         The Company's capital and exploration budget for 1997, which 
does not include any amounts that may be expended for the purchase of 
proved reserves or any interest which may be capitalized resulting from 
projects in progress, was established by the Company's Board of Directors
at $210,000,000.  In addition to anticipated 
capital and exploration expenses, other material 1997 cash requirements 
that the Company currently anticipates include ongoing operating, general 
and administrative, income tax, interest expense and the payment of 
dividends on its common stock, 
including a $.03 per share dividend on its common stock to be paid on 
August 22, 1997 to stockholders of record as of August 8, 1997.  
The Company currently anticipates that its available cash and cash 
investments, cash provided by operating 
activities and funds available under 
its revolving credit facility and

uncommitted lines of credit with banks will be sufficient to fund 
the Company's ongoing expenses, its 1997 capital and exploration 
budget, any currently anticipated costs associated with the Company's  
Thailand projects during 1997 and anticipated future 
dividend payments.  The declaration of future dividends will depend upon, 
among other things, the Company's future earnings and financial condition,
liquidity and capital requirements, the general economic and regulatory
climate and other factors deemed relevant by the Company's Board of
Directors.

NEW DEBT INSTRUMENTS

2007 NOTES

         On May 22, 1997, the Company issued $100,000,000 of 8 3/4%
Senior Subordinated Notes due 2007 (the "2007 Notes").  The proceeds from
the issuance of the 2007 Notes were used to repay amounts outstanding under
the Company's bank revolving credit agreement, and to purchase short-term 
cash investments.  The 2007 Notes bear interest at a rate of 8 3/4%, 
payable semi-annually in arrears on May 15 and November 15 of each year, 
commencing November 15, 1997.  The 2007 Notes are general unsecured senior 
subordinated obligations of the Company and are subordinated in
right of payment to the Company's senior indebtedness, which currently 
includes its obligations under its bank revolving credit agreement and its
unsecured credit lines, but are senior in right of payment to its 
subordinated indebtedness, which currently includes the 2006 Notes
and the 2004 Notes.  The Company, at its option, may redeem the 2007 Notes 
in whole or in part, at any time on or after May 15, 2002, at a redemption 
price of 104.375% of their principal value and decreasing percentages 
thereafter.  No sinking fund payments are required on the 2007 Notes.  The
2007 Notes are redeemable at the option of any holder, upon the occurrence 
of a change of control (as defined in the indenture governing the 2007 Notes),
at 101% of their principal amount.  The indenture governing the 2007 Notes 
also imposes certain covenants on the Company (as more fully described therein)
that are customary for senior subordinated indebtedness generally,
including covenants limiting: incurrence of indebtedness, including senior
indebtedness; restricted payments; the issuance and sales of restricted 
subsidiary capital stock; transactions with affiliates; liens; disposition 
of proceeds of asset sales; non-guarantor restricted subsidiaries; dividends 
and other payment restrictions affecting restricted subsidiaries; and mergers,
consolidations and the sale of assets.
   
AMENDED AND RESTATED CREDIT AGREEMENT
         
          Effective August 1, 1997, the Company entered into an amended and 
restated credit agreement (the "Credit Agreement").  The Credit Agreement 
provides for an unsecured $250,000,000 revolving/term credit facility which 
will be fully revolving until July 1, 2000, after which the balance will 
be due in eight quarterly term loan installments, commencing October 31, 2000.
The amount that may be borrowed under the Credit Agreement may not exceed 
a borrowing base which is composed of both domestic and Thai properties less,
in certain circumstances, the present value of interest payments on a portion
of certain subordinated indebtedness, including the 2007 Notes.  
The domestic borrowing base is determined semi-annually by the lenders 
in accordance with the Credit Agreement, based primarily on the discounted 
present value of future net revenues from the Company's domestic oil and gas 
reserves.  The portion of the borrowing base which is composed of properties

located in the Kingdom of Thailand is also determined semi-annually, but may, 
at the lenders discretion, be redetermined once more during each semi-annual 
period. The value of this portion of the borrowing base is determined by the
lenders applying their usual and customary criteria for 
oil and gas evaluation.  As of August 1, 1997, the Company's total borrowing 
base, including both domestic and Thai properties, exceeded $250,000,000.  
The Credit Agreement is governed by various financial and other covenants, 
including requirements to maintain positive working capital (excluding 
current maturities of debt) and a fixed charge coverage ratio, and 
limitations on indebtedness, creation of liens, the prepayment of 
subordinated debt, the payment of dividends, mergers and consolidations, 
investments and asset dispositions.  In addition, the Company is prohibited
from pledging borrowing base properties as security for other debt.  
Borrowings under the Credit Agreement currently bear interest at  a base 
(prime) rate or LIBOR plus 5/8%, at the Company's option.  A commitment fee 
on the unborrowed amount under the Credit Agreement is also charged.  The 
commitment fee is currently 0.25% per annum on the unborrowed amount under 
the Credit Agreement that is designated as "active" and 0.10% per annum 
on the unborrowed amount under the Credit Agreement that is designated as 
"inactive."  Of the $250,000,000 that is currently available under the 
Credit Agreement (subject to borrowing base limitations), $125,000,000 
is designated as "active" and $125,000,000 is designated as "inactive."

                         W  I  T  N  E  S  S  E  T  H :

       WHEREAS, the Borrower, the Lenders, the Agent and the Co-Agent entered
into that certain Credit Agreement dated as of September 23, 1992, which Credit

<PAGE>
                                   ARTICLE I

                        DEFINITIONS AND ACCOUNTING TERMS

       SECTION 1.1.  Defined Terms.  The following terms (whether or not
underscored) when used in this Agreement, including its preamble and recitals,
shall, except where the context otherwise requires, have the following meanings
(such meanings to be equally applicable to the singular and plural forms
thereof):


       "Activation Amount" means, in each case, any portion of the Inactive
Revolving Loan Commitment Amount that is converted to Active Revolving Loan
Commitment Amount by the Borrower following notice to the Agent in connection
with any Borrowing pursuant to Section 2.3 or, if not in connection with a
Borrowing, in a notice to the Agent pursuant to Section 11.2.  Each Activation
Amount shall be in an amount equal to an integral multiple of $12,500,000.

       "Active Revolving Loan Commitment Amount" means, on any date,
$125,000,000, plus the net amount of all Activation Amounts, as such Active
Revolving Loan Commitment Amount may be changed from time to time pursuant to
Section 2.2.

       "Additional Costs" is defined in Section 4.3.

       "Affiliate" of any Person means any other Person which, directly or
indirectly, controls, is controlled by or is under common control with such
Person (excluding any trustee under, or any committee with responsibility for
administering, any Plan).  A Person shall be deemed to be "controlled by" any
other Person if such other Person possesses, directly or indirectly, power

              (a)    to vote 10% or more of the securities (on a fully diluted
       basis) having ordinary voting power for the election of directors or
       managing general partners; or

              (b)    to direct or cause the direction of the management and
       policies of such Person whether by contract or otherwise.

       "Agent" is defined in the preamble and includes each other Person as
shall have subsequently been appointed as the successor Agent pursuant to
Section 10.4.

       "Agreement" means, on any date, this Credit Agreement as originally in
effect on the Effective Date and as thereafter from time to time amended,
supplemented, amended and restated, or otherwise modified and in effect on such
date.

       "Alternate Reserve Report" means, as the context requires, either the
Alternate Thailand Reserve Report or the Alternate U.S. Reserve Report and,
when used in the plural, shall mean both such reserve reports.





                                       2
<PAGE>
       "Alternate Thailand Reserve Report" means a report, in form and detail
satisfactory to the Agent and the Required Lenders, on reserves updated
internally by the Borrower making adjustments for any changes in production
volumes, expenses, Applicable Prices and for dispositions of properties in the
six-month period subsequent to the immediately preceding Reserve Report Date
and based upon the immediately preceding Thailand Reserve Report and , at the
Borrower's option, for any acquisitions of properties not included in the
immediately preceding Thailand Reserve Report or the restoration to the
Thailand Borrowing Base of properties previously removed from the Thailand
Borrowing Base by the Borrower.

       "Alternate U.S. Reserve Report" means a report, in form and detail
satisfactory to the Agent and the Required Lenders, on reserves updated
internally by the Borrower making adjustments for any changes in production
volumes, expenses, Applicable Prices and for dispositions of properties in the
six-month period subsequent to the immediately preceding Reserve Report Date
and based upon the immediately preceding U.S. Reserve Report and, at the
Borrower's option, for any acquisitions of properties not included in the
immediately preceding U.S. Reserve Report or the restoration to the U.S.
Borrowing Base of properties previously removed from the U.S. Borrowing Base by
the Borrower.  If any report which purports to be an Alternate U.S. Reserve
Report and which is delivered by the Borrower pursuant to the terms of this
Agreement is unsatisfactory in substance, form or detail to Lenders with an
aggregate Percentage of at least 75%, or if Lenders with an aggregate
Percentage of 75% or more disagree with the estimate of Proved Reserves insofar
as such estimate reflects internal work by the Borrower rather than estimates
by independent engineers in the preceding U.S. Reserve Report, the Borrower
shall as promptly as practicable but in any event within 90 days provide to the
Agent and the Lenders an Alternate Reserve Report Review.  Such Alternate U.S.
Reserve Report so reviewed pursuant to the Alternate Reserve Report Review
shall qualify as an Alternate U.S. Reserve Report for purposes of this
Agreement.

       "Alternate Reserve Report Review" means a review of any Alternate
Reserve Report by Ryder Scott Company Petroleum Engineers or other independent
petroleum engineers (provided that such other engineers are satisfactory to the
Borrower, the Agent and the Required Lenders), which engineer shall, as a part
of such review, certify that the estimates in the Alternate Reserve Report are
reasonable estimates using generally accepted petroleum engineering and
evaluation principles and that the methods and procedures used in preparing the
Alternate Reserve Report are reasonable.  The principles to be utilized are
those set forth in the Standards Pertaining to the Estimating and Auditing of
Oil and Gas Reserve Information promulgated by the Society of Petroleum
Engineers.

       "Applicable Gas Price" means the average (rounded to the nearest $.01)
of the natural gas prices being used (including prices for future periods) by
the Agent and the Co-Agent for evaluation of oil and gas reserve lending
transactions in accordance with the Agent's and the Co-Agent's customary
standards (which prices, other than those fixed by contract and subject to BTU
adjustment to reflect the liquids content of Borrower's natural gas, will be
consistent with those then being applied to other borrowers of the Agent or Co-
Agent generally) as of each January 1 or July 1, as applicable; provided,
however, that for purposes of determining the Borrowing Base, production





                                       3
<PAGE>
volumes hedged under fixed price contracts or production volumes committed
under long-term sales contracts (in each case with counterparties acceptable to
the Agent and the Co-Agent) will be included in the Reserve Reports at the
contracted price and the Applicable Gas Price will be BTU-adjusted to reflect
the liquids content of Borrower's natural gas.

        "Applicable Margin" means, at any time that the Borrower's Implied
Senior Debt Rating is equal to any rating set forth below, the percentage per
annum set forth opposite such Implied Senior Debt Rating in the column that is
applicable at that time, determined by reference to the percentage of the
Borrowing Base that the outstanding Loans represent at that time; provided,
that for purposes of determining the Applicable Margin if the Borrower's
Implied Senior Debt Rating shall change at any time for purposes of the grid
set forth below, such new Implied Senior Debt Rating  shall become effective on
the immediately next Quarterly Payment Date:

       "Updated Reserve Report" means a reserve report prepared internally by
the Borrower and which shall have been reviewed by Ryder Scott Company
Petroleum Engineers or another independent petroleum engineer satisfactory to
the Agent and the Required Lenders who shall have certified that the estimates
in the Updated Reserve Report are reasonable estimates using generally accepted
petroleum engineering and evaluation principles and that the methods and
procedures used in preparing the Updated Reserve Report are reasonable.  The
principles to be utilized are those set forth in the Standards Pertaining to
the Estimating and Auditing of Oil and Gas Reserve Information promulgated by
the Society of Petroleum Engineers.  If any report which purports to be an
Updated Reserve Report and which is delivered by the Borrower pursuant to the
terms of this Agreement is unsatisfactory in substance, form or detail to
Lenders with an aggregate Percentage of at least 75%, or if Lenders with an
aggregate Percentage of 75% or more disagree with the estimate of Proved
Reserves, the Borrower shall, as promptly as practicable but in any event
within 90 days deliver to the Agent and the Lenders an Audited Reserve Report
of independent petroleum engineers (other than the engineers which reviewed the
report previously deemed unsatisfactory by such Lenders) which engineers are
satisfactory to the Borrower and the Agent.  The Updated Reserve Report so
certified or revised by the Audited Reserve Report shall qualify as an Updated
Reserve Report for the purposes of this Agreement.

       "U.S. Borrowing Base" means, at any time, that amount, determined in

Net Income for each category of Proved Reserves located in the United States
multiplied by (b) the relevant Applicable Percentage for each category of such
Proved Reserves, and (ii) the product of 10/7 times sixty-five percent (65%) of
the Discounted Present Value of Future Net Income attributable to the Proved
Developed Producing Reserves located in the United States.  During the period
from August 1, 1997, to the date of the next determination of the U.S.
Borrowing Base pursuant to the provisions of Section 7.2, the amount of the
U.S. Borrowing Base shall be One Hundred and Seventy-Four Million, Nine Hundred
Thousand Dollars ($174,900,000).

       "U.S. Reserve Report" means a report of Ryder Scott Company Petroleum
Engineers or other independent petroleum engineers satisfactory to the Agent
and the Required Lenders showing, in form and detail satisfactory to the Agent
and Required Lenders, such engineers' estimate of the Proved Reserves on the
Borrowing Base Properties located in the United States and the future Gross
Revenue and Future Net Income to be derived from such Proved Reserves as of the
Reserve Report Date for each year.  The Reserve Report shall estimate the
Proved Reserves and income data for the Proved Developed Producing Reserves,
the Proved Developed Shut-In Reserves, the Proved Developed Behind Pipe
Reserves and the Proved Undeveloped Reserves, and shall, in each case,





                                       24
<PAGE>
report only the Proved Reserves and income data attributable to Borrower's
working interest percentage in or Borrower's pro rata share of, as the case may
be, any Proved Reserves located on the Borrowing Base Properties located in the
United States, less the Borrower's obligations or pro rata share of such
obligations, as the case may be, for advance payments for each such property.
All calculations including the calculation of Applicable Prices in the Reserve
Report shall be made on a property-by-property and an interest-by-interest
basis in order to reflect the varying royalties, costs and expenses, working
interests and advance payments applicable to the various Borrowing Base
Properties covered by the Reserve Report.  Except as otherwise specifically
required herein, the Reserve Report shall be prepared and presented in
accordance with the requirements of the S.E.C. from time to time in effect.  If
any report which purports to be a Reserve Report and which is delivered by the
Borrower pursuant to the terms of this Agreement is unsatisfactory in
substance, form or detail to Lenders with an aggregate Percentage of at least
75%, or if Lenders with an aggregate Percentage of 75% or more disagree with
the engineers' estimate of Proved Reserves, the Borrower shall, as promptly as
practicable but in any event within 90 days of notice to the Borrower by the
Agent that such report is not satisfactory, deliver to the Agent and the
Lenders an Audited Reserve Report of independent petroleum engineers (other
than the engineers which prepared the report previously deemed unsatisfactory
by such Lenders) which engineers are satisfactory to the Borrower and the
Agent.  The Reserve Report so certified or revised by the Audited Reserve
Report shall qualify as a Reserve Report for the purposes of this Agreement.

       "Welfare Plan" means a "welfare plan", as such term is defined in
section 3(1) of ERISA.

       SECTION 1.2.  Use of Defined Terms.  Unless otherwise defined or the

Agreement shall have such meanings when used in the Disclosure Schedule and in
each Note, Borrowing Request, Continuation/Conversion Notice, Loan Document,
notice and other communication delivered from time to time in connection with
this Agreement or any other Loan Document.

specified, all accounting terms used herein or in any other Loan Document shall
be interpreted, all accounting determinations and computations hereunder or
thereunder (including under Section 8.4) shall be made, and all financial

in accordance with, those generally accepted accounting principles ("GAAP")
applied in the preparation of the financial statements referred to in Section
6.5.

                                   ARTICLE II

                  COMMITMENTS, BORROWING PROCEDURES AND NOTES

       SECTION 2.1.  Commitments.  On the terms and subject to the conditions
of this Agreement (including Article V), each Lender severally agrees to make
Loans pursuant to the Commitments described in this Section 2.1.

       SECTION 2.1.1.       Revolving Loan Commitment.  From time to time on
any Business Day occurring prior to the Revolving Loan Commitment Termination
Date, each Lender will make revolving loans (relative to such Lender, its
"Revolving Loan") to the Borrower equal to such Lender's Percentage of the
aggregate amount of the Borrowing requested by the Borrower to be made on such
day.  The Commitment of each Lender described in this Section 2.1.1 is herein
referred to as its "Revolving Loan Commitment".  On the terms and subject to
the conditions hereof, the Borrower may from time to time borrow, prepay and
reborrow Revolving Loans.

       SECTION 2.1.2.       Term Loan Commitment.  On the Revolving Loan
Commitment Termination Date (unless such date shall occur as a result of clause
(c) of the definition thereof), each Lender will make one term loan (relative
to such Lender its "Term Loan") to the Borrower equal to the lesser of the then
outstanding principal amount of its Revolving Loan and the amount described in
Section 2.1.3(b).  The Commitment of each Lender described in this Section
2.1.2 is herein referred to as its "Term Loan Commitment".  No amounts paid or
prepaid with respect to the Term Loan may be reborrowed.  Fixed Rate Loans for
which the Interest Period shall not have terminated as of the Revolving Loan
Commitment Termination Date shall be continued as Fixed Rate Loans for the
applicable Interest Period and Prime Rate Loans shall be continued as Prime
Rate Loans after the Revolving Loan Commitment Termination Date, unless the
Borrower shall have elected otherwise by delivery of a Continuation/Conversion
Notice pursuant to Section 2.4; provided that such Fixed Rate Loans which shall
have converted to Term Loans shall be in a minimum amount of $5,000,000 and an
integral multiple of $1,000,000.  Any principal repayments received on the
Revolving Loan Commitment Termination Date for Revolving Loans not converted
into Term Loans shall be applied first to Prime Rate Loans and, after Prime
Rate Loans have been paid in full, to Fixed Rate Loans, unless the Borrower
shall have otherwise instructed the Agent in writing.  Upon a Lender making
such Term Loan, its Term Loan Commitment shall terminate and it shall have no
further Commitment to make Loans.

       SECTION 2.1.3.       Lenders Not Permitted or Required To Make Loans in
Excess of Commitment.  No Lender shall be permitted or required to make any
Loan if, after giving effect thereto,

              (a)    in the case of Revolving Loans, the aggregate outstanding
       principal amount of all Revolving Loans outstanding would exceed the
       lesser of (i) the Revolving Loan Commitment Amount and (ii) the
       Borrowing Base then in effect minus all other Senior Debt outstanding;





                                       26
<PAGE>
              (b)    in the case of Term Loans, the aggregate original
       principal amount of all Term Loans would exceed the Term Loan Commitment
       Amount;

              (c)    in the case of Revolving Loans, the aggregate outstanding
       principal amount of all Revolving Loans of any such Lender would exceed
       such Lender's Percentage of the Revolving Loan Commitment Amount; or

              (d)    in the case of Term Loans, the aggregate outstanding
       principal amount of the Term Loan of any such Lender would exceed such
       Lender's Percentage of the Term Loan Commitment Amount.

       SECTION 2.2.  Termination, Reduction, Redesignation and Extension of the
Commitment Amounts.  Each of the Commitment Amounts is subject to reduction
from time to time pursuant to this Section 2.2.

       SECTION 2.2.1.Optional.  The Borrower may, from time to time on
any Business Day occurring after the time of the initial Borrowing hereunder,
voluntarily reduce the amount of any Commitment Amount; provided, however, that
all such reductions shall require at least three Business Days' prior notice to
the Agent and specifying whether such reduction is a permanent reduction or
whether it is in connection with a redesignation of a portion of the Active
Revolving Loan Commitment Amount or the Inactive Revolving Loan Commitment
Amount, whether, if permanent,  the reduction relates to the Active Revolving
Loan Commitment Amount or the Inactive Revolving Loan Commitment Amount, and
the amount by which such Commitment Amount is being reduced or redesignated
which amount shall be limited as follows:

              (a)    with respect to any reduction or redesignation of the
       Active Revolving Loan Commitment Amount, (i) if such reduction is a
       permanent reduction, such reduction shall be in a minimum amount of
       $5,000,000 and in increments of $1,000,000, and (ii) if such reduction
       is a redesignation by the Borrower of a portion of the Active Revolving
       Loan Commitment Amount as a part of the Inactive Revolving Loan
       Commitment Amount, then (A) such reduction shall be in a minimum amount
       of $12,500,000 and in increments of $12,500,000 and (B) such reduction
       shall never result in the Active Revolving Loan Commitment Amount being
       less than $100,000,000; and

              (b)    with respect to any reduction or redesignation of the
       Inactive Revolving Loan Commitment Amount, (i) if such reduction is a
       permanent reduction, such reduction shall be in a minimum amount of
       $5,000,000 and in increments of $2,500,000 and (ii) if such reduction is
       a redesignation by the Borrower of a portion of the Inactive Revolving
       Loan Commitment Amount into a part of the Active Revolving Loan
       Commitment Amount as part of a Activation Amount, then such reduction
       shall be in a minimum amount of $12,500,000 and in increments of
       $12,500,000.





                                       27

              SECTION 2.2.2.       Mandatory as to Revolving Loans.  The
       Revolving Loan Commitment Amount shall be reduced or terminated as
       described below:

              (a)    Each Lender's Revolving Loan Commitment shall be
       automatically terminated on the Revolving Loan Commitment Termination
       Date.

              (b)    Each reduction in the Revolving Loan Commitment Amount
       hereunder shall be made ratably among the Lenders in accordance with
       their respective Percentages.  The Borrower shall pay to the Agent for
       the account of the Lenders, on the date of each termination or
       reduction, the Commitment Fees accrued pursuant to Section 3.4.1 on the
       amount of Commitments so terminated or reduced through the date of such
       termination or reduction.

              (c)    Should the Commitment Amount exceed the Borrowing Base at
       any time, the Commitment Amount shall be reduced to the Borrowing Base
       that is then in effect.  Such reduction in Commitments shall be
       allocated first to the Inactive Revolving Credit Commitment Amount until
       such Inactive Revolving Credit Commitment Amount is reduced to zero and
       thereafter to the Active Revolving Credit Commitment Amount.

       SECTION 2.2.3.Mandatory as to Term Loans.  The Term Loan
Commitment Amount shall be reduced or terminated as described below:

              (a)    Each Lender's Term Loan Commitment shall be automatically
       terminated on the Term Loan Commitment Termination Date.

              (b)    Each reduction in the Term Loan Commitment Amount
       hereunder shall be made ratably among the Lenders in accordance with
       their respective Percentages.

       SECTION 2.3.  Borrowing Procedure.  The Borrower may from time to time
irrevocably request that a Borrowing be made in a minimum amount of (i)
$1,000,000 for Prime Rate Loans and (ii) $5,000,000 for LIBO Rate Loans, and in
an integral multiple of $1,000,000 or in the case of a Revolving Loan, in the
unused amount of the Revolving Loan Commitment Amount.  Such request shall be
made by delivering a Borrowing Request to the Agent on or before 10:00 a.m.
United States Central time, (x) on the Business Day of such Borrowing in the
case of a Prime Rate Borrowing and (y) on a Business Day not less than three
Business Days in advance of a LIBO Rate Borrowing.  On the terms and subject to
the conditions of this Agreement, each Borrowing shall be comprised of the Type
of Loans, and shall be made on the Business Day, specified in such Borrowing
Request.  With respect to any Borrowing, the Agent shall have given each of the
Lenders notice of such Borrowing on or before 10:30 a.m. United States Central
time on the date of such Borrowing and on or before 11:00 a.m. United States
Central time on such Business Day each Lender shall deposit with the Agent same
day funds in an amount equal to such Lender's Percentage of the requested
Borrowing.  Such deposit will be made to an account which the Agent shall
specify from time to time by notice to the Lenders.  To the extent funds are
received from the Lenders, the Agent shall make such funds





                                       28
<PAGE>
available to the Borrower by wire transfer to the accounts the Borrower shall
have specified in its Borrowing Request.  No Lender's obligation to make any
Loan shall be affected by any other Lender's failure to make any Loan.

       SECTION 2.4.  Continuation and Conversion Elections.  The Borrower may
from time to time irrevocably elect that all, or any portion in an aggregate
minimum amount of $5,000,000 and an integral multiple of $1,000,000, of any
Borrowing be, in the case of Prime Rate Loans, converted into Fixed Rate Loans
or, in the case of Fixed Rate Loans, be converted into Prime Rate Loans or
continued as Fixed Rate Loans of the same or different Type.  Such request for
a continuation or conversion of a Borrowing shall be made by delivering a
Continuation/Conversion Notice to the Agent on or before 10:00 a.m., United
States Central time, on a Business Day, such Continuation/Conversion Notice to
be delivered at least three Business Days in advance for any Borrowing
continued as or converted into a LIBO Rate Loan. In the absence of delivery of
a Continuation/Conversion Notice with respect to any LIBO Rate Loan at least
three Business Days before the last day of the then current Interest Period
with respect thereto, such Fixed Rate Loan shall, on such last day,
automatically convert to a Prime Rate Loan. Notwithstanding the above, no
portion of the outstanding principal amount of any Loans may be continued as,
or be converted into, Fixed Rate Loans when any Default has occurred and is
continuing.

       SECTION 2.5.  Funding.  Each Lender may, if it so elects, fulfill its
obligation to make, continue or convert Fixed Rate Loans hereunder by causing
one of its foreign branches or Affiliates (or an international banking facility
created by such Lender) to make or maintain such Fixed Rate Loan; provided,
however, that such Fixed Rate Loan shall nonetheless be deemed to have been
made and to be held by such Lender, and the obligation of the Borrower to repay
such Fixed Rate Loan shall nevertheless be to such Lender for the account of
such foreign branch, Affiliate or international banking facility.  In addition,
the Borrower hereby consents and agrees that, for purposes of any determination
to be made for purposes of Sections 4.1, 4.2, 4.3 or 4.4, it shall be
conclusively assumed that each Lender elected to fund all Fixed Rate Loans by
purchasing Dollar deposits in its LIBO Office's interbank Eurodollar market.

       SECTION 2.6.  Determination of Borrowing Base.  Upon delivery of a
Reserve Report or Alternate Reserve Report pursuant to Section 7.2 hereof and
provided, that (i) such delivery shall be on or before the dates required
therein and (ii) such Reserve Report or Alternate Reserve Report shall not have
been found unsatisfactory in substance, form or detail, or unsatisfactory by
reason of the estimates of Proved Reserves contained therein, by Lenders with
an aggregate Percentage of at least 75%, then:

              (a)    With respect to the annual or semi-annual, as the case may
       be, determination of the U.S. Borrowing Base, the Agent will notify the
       Borrower of the new U.S. Borrowing Base on or before (i) the next April
       30th, in the case of a U.S. Reserve Report and (ii) the next October
       31st, in the case of an Alternate U.S. Reserve Report, which U.S.
       Borrowing Base shall remain in effect until the next October 31st or
       April 30th (subject to delivery of an Updated Reserve Report pursuant to
       Sections 3.1.2 or 3.1.3 and the





                                       29
<PAGE>
       determination of a Revised Borrowing Base); provided that, if pursuant
       to  Reserve Reports dated January 1st of any year the ratio of (x)
       Borrowing Base to (y) Commitment Amount plus the amount of Senior Debt
       (other than the Loans) that is outstanding on such date which is
       permitted pursuant to Section 8.2(a)(ii) is at least 1.5 to 1.0, then
       the Agent shall not redetermine the U.S. Borrowing Base pursuant to the
       Alternate U.S. Reserve Report and shall not notify the Borrower of any
       redetermination of the U.S. Borrowing Base pursuant to the Alternate
       U.S. Reserve Report dated as of July 1st of such year.  Notwithstanding
       the foregoing, if any Reserve Report or Alternate Reserve Report
       pursuant to which a Borrowing Base is to be determined shall have been
       unsatisfactory in form, substance or detail, or unsatisfactory by reason
       of the estimates of Proved Reserves therein, to Lenders with an
       aggregate Percentage of at least 75%, then the Borrowing Base in effect
       as of the Reserve Report Date of such Reserve Report or Alternate
       Reserve Report shall remain in effect until (i) the Borrower shall have
       delivered to the Agent and the Lenders an Audited Reserve Report or the
       results of an Alternate Reserve Report Review, as the case may be, which
       report shall be delivered within 90 days of notice from the Agent to the
       Borrower that the Reserve Report or Alternate Reserve Report, as the
       case may be, was not satisfactory, and (ii) the Agent shall have
       notified the Borrower of the new Borrowing Base, which notification
       shall be made within 5 Business Days of the delivery of such Audited
       Reserve Report or the results of such Alternate Reserve Report Review.

              (b)    With respect to the semi-annual redetermination of the
       Thailand Borrowing Base, the Agent will propose to the Lenders a
       Thailand Borrowing Base for acceptance by the Majority Borrowing Base
       Lenders.  If such Thailand Borrowing Base, as proposed by the Agent is
       accepted by the Majority Borrowing Base Lenders, then such agreed
       Thailand Borrowing Base shall be communicated by the Agent to the
       Borrower on or before (i) the next April 30th, in the case of a Thailand
       Reserve Report and (ii) the next October 31st, in the case of an
       Alternate Thailand Reserve Report, and shall remain in effect until the
       next October 31st or April 30th; provided that if such proposed Thailand
       Borrowing Base is not approved by the Majority Borrowing Base Lenders
       prior to the applicable date then, within thirty (30) days following the
       applicable date, the Majority Borrowing Base Lenders will establish and
       agree to a Thailand Borrowing Base, and such amount will be promptly
       communicated to the Borrower; provided that the then current Thailand
       Borrowing Base shall remain in effect until the Borrower is notified of
       the new Thailand Borrowing Base.  The Thailand Borrowing Base, as
       determined and established pursuant to this Section 2.6(b) shall be
       subject, at all times, to the determination of a Revised Borrowing Base
       as a result of (A) the delivery by the Borrower, and approval by the
       Majority Borrowing Base Lenders, of an Updated Reserve Report pursuant
       to Sections 3.1.2 or 3.1.3 or (B) a Non-Standard Determination.

              (c)    With respect to a redetermination of the Thailand
       Borrowing Base resulting from a Non-Standard





                                       30
<PAGE>
       Determination, the Agent or the Required Lenders shall have the right,
       but not the obligation on no more than one occasion during each six
       month period ending on April 30th and October 31st, to notify the
       Borrower of its intent to perform a Non-Standard Determination of the
       Thailand Borrowing Base.  As part of such Non-Standard Determination,
       the Agent shall propose, and the Majority Borrowing Base Lenders shall
       agree to and approve, a new Thailand Borrowing Base which shall become
       effective upon receipt by the Borrower of notice of such new Thailand
       Borrowing Base until such new Thailand Borrowing Base may be
       redetermined as a result of (i) a semi-annual determination of the
       Thailand Borrowing Base pursuant to Section 2.6(b) or (ii) the delivery
       by the Borrower, and approval by the Majority Borrowing Base Lenders, of
       an Updated Reserve Report pursuant to Sections 3.1.2 or 3.1.3.

       SECTION 2.7.  Notes.  Each of the Lenders' Loans under a Commitment
shall be evidenced by a Note payable to the order of such Lender in a maximum
principal amount equal to such Lender's Percentage of the original applicable
Commitment Amount.  The Borrower hereby irrevocably authorizes each Lender to
make (or cause to be made) appropriate notations on the grid attached to such
Lender's Note (or on any continuation of such grid), which notations, if made,
shall evidence, inter alia, the date of, the outstanding principal of, and the
interest rate and Interest Period applicable to the Loans evidenced thereby.
Such notations shall be conclusive and binding on the Borrower absent manifest
error; provided, however, that the failure of any Lender to make any such
notations shall not limit or otherwise affect any Obligations of the Borrower.

                                  ARTICLE III

                   REPAYMENTS, PREPAYMENTS, INTEREST AND FEES

       SECTION 3.1.  Repayments and Prepayments.   The Borrower shall make
mandatory repayments and prepayments and may also make voluntary prepayments
from time to time pursuant to this Section 3.1.  Each prepayment of any Loans
made pursuant to this Section shall be without premium or penalty, except as
may be required by Section 4.4.

       SECTION 3.1.1.Repayments.  To the extent that Term Loans are made
to the Borrower on the Revolving Loan Commitment Termination Date, such Term
Loans shall be deemed to be for repayment of the principal of Revolving Loans
outstanding as of the Revolving Loan Commitment Termination Date.  The Borrower
shall repay in full the unpaid aggregate principal amount of each Loan upon the
Stated Maturity Date therefor.  Prior thereto, the Borrower shall, on each
Quarterly Payment Date occurring after the Revolving Loan Commitment
Termination Date, make a scheduled repayment of the outstanding principal
amount of the Term Loans (i) on each of the first four Quarterly Payment Dates
following the Revolving Loan Commitment Termination Date (or if any such day is
not a Business Day, the next succeeding Business Day), each in an amount equal
to 15% of the original principal amount of the Term Loan and (ii) on each of
the next four Quarterly Payment Dates thereafter, in an amount equal to 10% of
the original principal amount of the Term Loan; provided that, in the event
that the first Quarterly Payment Date falls on a date that is less than eighty-
eight (88) days after conversion of a Revolving Loan to a Term Loan, the first
Quarterly Payment Date for such Term Loan shall be the next succeeding
Quarterly Payment Date and provided further





                                       31
<PAGE>
that, the final scheduled repayment shall be in an amount necessary to repay in
full the unpaid principal of the Term Loan.
                     
       SECTION 3.1.2. Mandatory Prepayments on Revolving Loans.  If at
any time prior to the Revolving Loan Commitment Termination Date, the aggregate
principal amount of all Senior Debt outstanding shall exceed the Borrowing Base
then in effect, the Borrower shall, at the Borrower's option, either (i)
forthwith repay the Revolving Loans in an aggregate amount equal to such excess
or (ii) prepay the Revolving Loans, in no more than five substantially equal
monthly installments, in an amount such that upon the conclusion of such
mandatory prepayments, the aggregate principal amount of all outstanding Senior
Debt will not exceed the Borrowing Base.

              (a)    If the Thailand Borrowing Base as redetermined pursuant to
       a Non-Standard Determination decreases by an amount equal to or greater
       than $25,000,000 and the aggregate principal amount of all Senior Debt
       outstanding exceeds the Borrowing Base because of a redetermination of
       the Thailand Borrowing Base pursuant to a Non-Standard Determination
       thereby resulting in the commencement of a Deficiency Period, then the
       first payment pursuant to Clause (ii) above shall be due within 90 days
       after the date on which the Borrower is notified of the amount of the
       new Thailand Borrow Base as determined pursuant to such Non-Standard
       Determination, and the remaining payments shall be due on the
       numerically corresponding day of each of the subsequent months.  If a
       subsequent month does not contain a numerically corresponding day, the
       Borrower shall make such payment on the last Business Day of such month,
       or if the numerically corresponding day is not a Business Day, such
       payment will be due on the preceding Business Day.

              (b)    Except as provided in Section 3.1.2(c) below, if the
       aggregate principal amount of all Senior Debt outstanding exceeds the
       Borrowing Base at any time for any other reason other than as described
       in Section 3.1.2(a) above, the first such payment pursuant to Clause
       (ii) above shall be due within 30 days after the commencement date of a
       Deficiency Period (or the date on which the Borrower is notified of a
       new Thailand Borrowing Base pursuant to a Non-Standard Determination, if
       such Non-Standard Determination results in the commencement of a
       Deficiency Period), and the remaining payments shall be due on the
       numerically corresponding day of each of the subsequent months.  If a
       subsequent month does not contain a numerically corresponding day, the
       Borrower shall make such payment on the last Business Day of such month,
       or if the numerically corresponding day is not a Business Day, such
       payment will be due on the preceding Business Day.

              (c)    If any Reserve Report or Alternate Reserve Report, which
       pursuant to Section 2.6,  serves as the basis for the redetermination of
       the Borrowing Base, shall be found unsatisfactory in substance, form or
       detail, or unsatisfactory by reason of the estimate of Proved Reserves,
       by Lenders having an aggregate Percentage of at least 75% and, upon the
       delivery of an Audited





                                       32
<PAGE>
       Reserve Report or the results of an Alternate Reserve Report Review, as
       the case may be, by the Borrower, the aggregate principal amount of all
       Senior Debt outstanding exceeds the Borrowing Base then in effect
       determined pursuant to such Audited Reserve Report or Alternate Reserve
       Report Review, then the Deficiency Period shall be deemed to have begun
       on (i)(A) the April 30th or (B) the May 30th (if the Borrowing Base
       determination is delayed by the Lenders pursuant to Section 2.6(b))
       following the date of an Audited Reserve Report relating to a Reserve
       Report (or the first date thereafter on which  Senior Debt outstanding
       shall have exceeded the Borrowing Base as determined pursuant to the
       Audited Reserve Report) or (ii) (A) the October 31st or (B) the November
       30th  (if the Borrowing Base determination is delayed by the Lenders
       pursuant to Section 2.6(b)) following the date of an Alternate Reserve
       Report so reviewed pursuant to the Alternate Reserve Report Review (or
       the first date thereafter on which Senior Debt outstanding shall have
       exceeded the Borrowing Base as determined pursuant to such Alternate
       Reserve Report Review) and, upon notification by the Agent of the new
       Borrowing Base, any and all mandatory prepayments of principal which,
       pursuant to the immediately preceding paragraph, would have been due and
       payable on or prior to the date of such notice from the Agent during the
       Deficiency Period beginning on the date so deemed the beginning date for
       such Deficiency Period, together with accrued interest thereon, shall be
       immediately due and payable.

              (d)     During any Deficiency Period, the Borrower may deliver to
       the Lenders an Updated Reserve Report. If the Updated Reserve Report (i)
       reflects a revised U.S. Borrowing Base or results in the Majority
       Borrowing Base Lenders approving an increase in the Thailand Borrowing
       Base  ( as so revised and increased, the "Revised Borrowing Base"), (ii)
       is satisfactory in form, substance and detail and as to the estimates of
       Proved Reserves located in the United States, to the Lenders and/or the
       Agent as required by the definition of "Updated Reserve Report" and
       (iii) such Updated Reserve Report evidences an increase in Proved
       Reserves located in the United States over those shown in the Reserve
       Reports or Alternate Reserve Reports, as applicable, most recently
       previously delivered pursuant to Section 7.2 or, with respect to the
       Thailand Borrowing Base, such Updated Reserve Report results in the
       Majority Borrowing Base Lenders agreeing to increase the Thailand
       Borrowing Base from the then current amount (such determination whether
       to increase the Thailand Borrowing Base from its then current amount,
       and if so determined, the amount by which such Thailand Borrowing Base
       is to be increased, to be made by the Majority Borrowing Base Lenders
       within thirty (30) days after receipt of an Updated Reserve Report
       relating to Borrowing Base Properties located in the Kingdom of
       Thailand) as previously determined by the Majority Borrowing Base
       Lenders pursuant to Sections 2.6(b) or 2.6(c), the installment payments
       otherwise required pursuant to this Section 3.1.2 shall be reduced or
       eliminated, as the case may be, to the extent that the aggregate
       principal amount of all Senior Debt does not exceed the Revised
       Borrowing Base.

       SECTION 3.1.3. Mandatory Prepayments on Term Loans.  If at any
time after the making of the Term Loans, the ratio of (a) the Discounted
Present Value of Future Net Income attributable to Proved Reserves located in
the United States (provided that at least 7/10 times such Discounted Present
Value of Future Net Income is attributable to the Proved Developed Producing
Reserves) (based on the data in the Reserve Report or Alternate Reserve Report,
as the case may be), to (b) the difference of the outstanding principal amount
of the Senior Debt less the Thailand Borrowing Base





                                       33
<PAGE>
(as last determined by the Required Lenders pursuant to Sections 2.6(b) or
2.6(c)) shall at any time be less that 1.5 to 1.0, the Borrower shall, at the
Borrower's option, either (i) forthwith repay Term Loans in an aggregate amount
equal to such deficiency, or (ii) prepay the Term Loans, in no more than five
substantially equal monthly installments, in an amount such that, upon the
conclusion of such mandatory prepayments, such ratio would be at least 1.5 to
1.0.  The first such payment pursuant to clause(ii) above shall be due within
30 days after the date on which it is first determined that such ratio is less
than 1.5 to 1.0, and the remaining payments shall be due on the numerically
corresponding day of each of the subsequent months.  If a subsequent month does
not contain a numerically corresponding day, the Borrower shall make such
payment on the last Business Day of such month, or if the numerically
corresponding day is not a Business Day, such payment will be due on the
preceding Business Day.

              (a)    If any Reserve Report or Alternate Reserve Report which,
       pursuant to Section 2.6, serves as the basis for the redetermination of
       the Borrowing Base shall be found unsatisfactory in substance, form or
       detail, or unsatisfactory by reason of the estimate of Proved Reserves,
       by Lenders having an aggregate Percentage of at least 75% and, upon the
       delivery of an Audited Reserve Report or the results of an Alternate
       Reserve Report Review, as the case may be, by the Borrower, the ratios
       set forth in Clauses (a) and (b) of the preceding paragraph are not
       satisfied, then the Deficiency Period shall be deemed to have begun on
       the April 30th or (B) May 30th  (if the Borrowing Base determination is
       delayed by the Lenders pursuant to Section 2.6(b)) following the date of
       such Audited Reserve Report relating to a Reserve Report (or the first
       date thereafter on which the ratios set forth in Clauses (a) and (b) of
       the preceding paragraph are not satisfied) or (ii)(A) the October 31st
       or (B) November 30th (if the Borrowing Base determination is delayed by
       the Lenders pursuant to Section 2.6(b)) following the date of an
       Alternate Reserve Report so reviewed by an Alternate Reserve Report
       Review relating to an Alternate Reserve Report  (or the first date
       thereafter on which the ratios set forth in Clauses (a) and (b) of the
       preceding paragraph are not satisfied) and, upon notification by the
       Agent of the new Borrowing Base, any mandatory prepayments of principal
       which, pursuant to the immediately preceding paragraph, would have been
       due and payable on or prior to the date of such notice from the Agent
       during the Deficiency Period beginning on the date so deemed the
       beginning date for such Deficiency Period, together with accrued
       interest thereon, shall be immediately due and payable.

              (b)    Mandatory prepayments pursuant to this Section 3.1.3 shall
       be in addition to and not in lieu of payments required pursuant to
       Section 3.1.1.  Mandatory prepayments pursuant to this Section 3.1.3
       shall be applied to the next scheduled repayment or repayments required
       pursuant to Section 3.1.1 if, as of such repayment date, after giving
       effect to such scheduled repayment, the ratios set forth in clauses (a)
       and (b) of the first paragraph of this Section 3.1.3 are satisfied,
       however, the repayments pursuant to Section 3.1.1 shall always be
       required.

              (c)    During any Deficiency Period, the Borrower may deliver to
       the Lenders an Updated Reserve Report. If the Updated Reserve Report (i)
       reflects a Revised Borrowing





                                       34
<PAGE>
       Base (ii) is satisfactory in form, substance and detail, and as to
       estimates of Proved Reserves located in the United States, to the
       Lenders and/or Agent as required by the definition of "Updated Reserve
       Report" and (iii) such Updated Reserve Report evidences an increase in
       Proved Reserves located in the United States over those shown in the
       Reserve Reports or Alternate Reserve Reports, as applicable, most
       recently previously delivered pursuant to Section 7.2, the installment
       payments otherwise required pursuant to this Section 3.1.3 shall be
       reduced or eliminated, as the case may be, provided that after such
       reduction or elimination, the ratios set forth in this Section 3.1.3
       shall be satisfied as of the next installment payment date.

       SECTION 3.1.4. Repayment Upon Acceleration.  The Borrower shall,
immediately upon any acceleration of the Stated Maturity Date of any Loans
pursuant to Section 9.2 or 9.3, repay all Loans.

       SECTION 3.2.  Voluntary Prepayments.  The Borrower may, from time to
time on any Business Day prior to the Stated Maturity Date, make a voluntary
prepayment, in whole or in part, of the outstanding principal amount of all
Loans comprising the same Borrowing; provided, however, that

              (i)    any such prepayment shall be made pro rata among the
       Lenders with respect to Loans of the same Type and, if applicable,
       having the same Interest Period;

              (ii)   no such prepayment of any Fixed Rate Loan may be made on
       any day other than the last day of the Interest Period for such Loan;

              (iii)  all such voluntary prepayments of Fixed Rate Loans shall
       require at least one but no more than five Business Days' prior written
       notice to the Agent and the Lenders and all such voluntary prepayments
       of Prime Rate Loans shall require prior written notice to the Agent on
       or before 10:00 a.m. United States Central Time on the Business Day of
       such voluntary repayment; and

              (iv)   all such voluntary partial prepayments shall be in a
       minimum amount equal to $1,000,000 for Prime Rate Loans and $5,000,000
       for Fixed Rate Loans, and an integral multiple of $1,000,000.

No voluntary prepayment of principal of any Revolving Loan shall cause a
reduction in the Revolving Loan Commitment Amount.  No voluntary prepayment of
principal of any Term Loan may be reborrowed.  All voluntary prepayments of
Term Loans shall be applied to scheduled repayments as the Borrower may direct
by written notice to the Agent.

       SECTION 3.3.  Interest Provisions.  Interest on the outstanding
principal amount of Loans shall accrue and be payable in accordance with this
Section 3.3.





                                       35
<PAGE>
       SECTION 3.3.1. Rates.  Pursuant to an appropriately delivered
Borrowing Request or Continuation/Conversion Notice, the Borrower may elect
that Loans comprising a Borrowing accrue interest at a rate per annum:

              (a)    on that portion maintained from time to time as a Prime
       Rate Loan, equal to the Prime Rate from time to time in effect; and

              (b)    on that portion maintained as a LIBO Rate Loan, during
       each Interest Period applicable thereto, equal to the sum of the LIBO
       Rate for such Interest Period plus the Applicable Margin.

The LIBO Rate for any Interest Period for LIBO Rate Loans will be determined by
the Agent on the basis of the applicable rates furnished to and received by the
Agent from the Reference Banks, two Business Days before the first day of such
Interest Period.  All Fixed Rate Loans shall bear interest from and including
the first day of the applicable Interest Period to (but not including) the last
day of such Interest Period at the interest rate determined as applicable to
such Fixed Rate Loan.

       SECTION 3.3.2. Post-Maturity Rates.  After the date any principal
amount of any Loan is due and payable (whether on the Stated Maturity Date,
upon acceleration or otherwise), or after any other monetary Obligation of the
Borrower shall have become due and payable, the Borrower shall pay interest
(after as well as before judgment) on such amounts at a rate per annum equal to
the Prime Rate plus a margin of 2%.

       SECTION 3.3.3. Payment Dates.  Interest accrued on each Loan shall
be payable, without duplication:

              (a)    on the Stated Maturity Date therefor;

              (b)    on the date of any payment or prepayment, in whole or in
       part, of principal outstanding on such Loan;

              (c)    with respect to Prime Rate Loans, on each Quarterly
       Payment Date occurring after the date of the initial Borrowing
       hereunder;

              (d)    with respect to Fixed Rate Loans, the last day of each
       applicable Interest Period (and, if such Interest Period shall exceed 90
       days, on the 90th day of such Interest Period);

              (e)    with respect to any Prime Rate Loans converted into Fixed
       Rate Loans on a day when interest would not otherwise have been payable
       pursuant to clause (c), on the date of such conversion; and





                                       36
<PAGE>
              (f)    on any Loans the Stated Maturity Date of which is
       accelerated pursuant to Section 9.2 or Section 9.3, immediately upon
       such acceleration.

Interest accrued on Loans or other monetary Obligations arising under this
Agreement or any other Loan Document after the date such amount is due and
payable (whether on the Stated Maturity Date, upon acceleration or otherwise)
shall be payable upon demand.  Notwithstanding clauses (a) and (b) above,
except as otherwise provided in this Section 3.3.3, no accrued interest shall
be due and payable on the Revolving Loan Commitment Termination Date on those
Revolving Loans the principal of which is deemed to have been repaid by Term
Loans to the Borrower pursuant to Section 3.1.1.

       SECTION 3.3.4. Interest Rate Determination.  Each Reference Bank
agrees to furnish to the Agent timely information for the purpose of
determining the LIBO Rate.  If either of the Reference Banks shall fail to
timely furnish such information to the Agent for such interest rate, the Agent
shall determine such interest rate on the basis of information furnished by the
remaining Reference Bank.

       SECTION 3.3.5. Maximum Interest.  It is the intention of the
parties hereto to conform strictly to applicable usury laws and, anything
herein to the contrary notwithstanding, the obligations of the Borrower to the
Lenders under this Agreement, the Loan Documents and any other document or
instrument executed in connection herewith or therewith, shall be subject to
the limitation that payments of interest or of other amounts constituting
interest under applicable law to a Lender shall not be required to the extent
that receipt thereof would be in excess of the Highest Lawful Rate, or
otherwise contrary to provisions of law applicable to such Lender limiting
rates of interest which may be charged or collected by such Lender.
Accordingly, if the transactions or the amount paid or otherwise agreed to be
paid for the use, forbearance or detention of money under this Agreement, the
Loan Documents and any other document or instrument executed in connection
herewith or therewith would exceed the Highest Lawful Rate or otherwise be
usurious under applicable law (including the federal and state laws of the
United States of America, or of any other jurisdiction whose laws may be
mandatorily applicable) with respect to any Lender then, in that event,
notwithstanding anything to the contrary in this Agreement or the Loan
Documents and any other document or instrument executed in connection herewith
or therewith, it is agreed as follows as to such Lender:

              (a)    in respect to such Lender, the provisions of this Section
       3.3.5 shall govern and control over any other provision in this
       Agreement, the Loan Documents and any other document or instrument
       executed in connection herewith or therewith and each provision set
       forth therein is hereby so limited;

              (b)    the aggregate of all consideration which constitutes
       interest under applicable law that is contracted for, charged or
       received under this Agreement, or under any of the other aforesaid
       agreements or otherwise in connection with this Agreement by such Lender
       shall under no circumstances exceed the maximum amount of interest
       allowed by applicable law (such maximum lawful interest rate, if any,
       with respect to such Lender herein





                                       37
<PAGE>
       called the "Highest Lawful Rate"), and all amounts owed under this
       Agreement, the Loan Documents and any other document or instrument
       executed in connection herewith or therewith shall be held subject to
       reduction and (i) the amount of interest which would otherwise be
       payable to such Lender hereunder and under the Loan Documents and any
       other document or instrument executed in connection herewith or
       therewith, shall be automatically reduced to the amount allowed under
       applicable law and (ii) any unearned interest paid by the Borrower in
       excess of the Highest Lawful Rate shall be credited to the Borrower by
       such Lender (or, if such consideration shall have been paid in full,
       refunded to the Borrower);

              (c)    all sums paid, or agreed to be paid, to such Lender for
       the use, forbearance and detention of the indebtedness of the Borrower
       to such Lender hereunder shall, to the extent permitted by applicable
       law, be amortized, prorated, allocated and spread throughout the full
       term of such indebtedness until payment in full so that the actual rate
       of interest is uniform throughout the full term thereof;

              (d)    if at any time the interest provided pursuant to Sections
       3.3.1 or 3.3.2, as the case may be, together with any other fees payable
       pursuant to or in connection with this Agreement and deemed interest
       under applicable law, with respect to any Lender exceeds that amount
       which would have accrued at the Highest Lawful Rate, the amount of
       interest and any such fees to accrue to such Lender pursuant to this
       Agreement shall be limited, notwithstanding anything to the contrary in
       this Agreement to that amount which would have accrued at the Highest
       Lawful Rate for such Lender, but any subsequent reductions, as
       applicable, shall not reduce the interest to accrue pursuant to this
       Agreement below such Lender's Highest Lawful Rate until the total amount
       of interest payable to such Lender (including all consideration which
       constitutes interest) equals the amount of interest which would have
       been payable to such Lender (including all consideration which
       constitutes interest) assuming a varying rate per annum equal to the
       interest provided pursuant to Sections 3.3.1 and 3.3.2 at all times in
       effect, plus the amount of fees which would have been received but for
       the effect of this Section 3.3.5.

For purposes of Article 5069-1.04, Vernon's Texas Civil Statutes, as amended,
to the extent, if any, applicable to any Lender, the Borrower agrees that the
Highest Lawful Rate for such Lender shall be the "indicated (weekly) rate
ceiling" as defined in said Article, provided that such Lender may also rely,
to the extent permitted by applicable laws, on alternative maximum rates of
interest under other laws applicable to such Lender if greater.  To the extent
that Texas law shall be applicable to the determination of the Highest Lawful
Rate of any Lender, the provisions of Chapter 15 of Subtitle 3, Title 79 of the
Revised Civil Statutes of Texas, 1925, as amended, shall not apply to this
Agreement or the Notes.

       SECTION 3.4.  Fees.  The Borrower agrees to pay the fees set forth in
this Section 3.4.  All such fees shall be non-refundable.





                                       38
<PAGE>
       SECTION 3.4.1. Commitment Fee.   The Borrower agrees to pay to the
Agent for the account of each Lender, for the period (including any portion
thereof when any of Commitments are suspended by reason of the Borrower's
inability to satisfy any condition of Article V) commencing on the Effective
Date and continuing through the Revolving Loan Commitment Termination Date,
commitment fees (collectively, the "Commitment Fees") at a rate per annum for
each day of such period equal to a percentage determined by reference to the
following grid and the applicable Implied Senior Debt Rating of the Borrower
times such Lender's respective Percentage of the sum of the average daily
unused portion of  (i) the Active Revolving Loan Commitment Amount and (ii) the
Inactive Revolving Loan Commitment Amount:

In addition, on each occasion the Borrower elects to redesignate any portion of
the Inactive Revolving Loan Commitment Amount into an Active Revolving Loan
Commitment Amount, a fee on such Activation Amount equal to the product of (i)
1/4 of 1% of such Activation Amount, and (ii) the lesser of six (6) or the
number of calendar months (rounded to the next highest integer, not to exceed
six) that have elapsed since (A) the Effective Date or (B) the Inactive
Designation Date (as defined hereafter) (in either case, and as applicable, the
"Calculation Period").  For purposes of determining the Calculation Period, to
the extent that any Activation Amount is redesignated back into an Inactive
Revolving Loan Commitment Amount (the effective date of such redesignation
herein an "Inactive Designation Date") and then subsequently redesignated
herein an Activation Amount (such amount herein  a "Reactivated Amount"), the
Calculation Period in respect of the portion of the Activation Amount which is
equal to each such Reactivated Amount shall be determined, with respect to such

                                   ARTICLE IV

                     CERTAIN LIBO RATE AND OTHER PROVISIONS

       SECTION 4.1.  Fixed Rate Lending Unlawful.  If any Lender shall
determine (which determination shall, upon notice thereof to the Borrower and
the Lenders, be conclusive and binding on the Borrower if made in good faith)
that the introduction of or any change in or in the interpretation of any law
or regulation makes it unlawful for such Lender to make, continue or maintain
any Loan as, or to convert any Loan into, a Fixed Rate Loan, the obligations of
such Lender to make, continue, maintain or convert any such Loans shall, upon
such determination, forthwith be suspended until such Lender shall notify the
Agent that the circumstances causing such suspension no longer exist, and Fixed
Rate Loans of such Lender shall automatically convert into Prime Rate Loans at
the end of the then current Interest Periods with respect thereto or sooner, if
required by such law or regulation.

       SECTION 4.2.  Rates Unavailable.  If the Agent or the Required Lenders
shall have determined that by reason of circumstances affecting the Agent's or
the Required Lenders' relevant market, adequate means do not exist for
ascertaining the interest rate applicable hereunder to Fixed Rate Loans of such
Type, then, upon notice from the Agent (given at the direction of the Required
Lenders if such determination shall have been made by the Required Lenders) to
the Borrower and the Lenders, the obligations of all Lenders under Section 2.3
and Section 2.4 to make or continue any Loans as, or to convert any Loans into,
Fixed Rate Loans shall forthwith be suspended until the Agent shall notify the
Borrower and the Lenders that the circumstances causing such suspension no
longer exist.

       SECTION 4.3.  Increased Fixed Rate Loan Costs, etc.  The Borrower agrees
to reimburse each Lender for any increase in the cost to such Lender of, or any
reduction in, the amount of any sum receivable by such Lender in respect of,
making, continuing or maintaining (or of its obligation to make, continue or
maintain) any Loans as, or of converting (or of its obligation to convert) any
Loans into, Fixed Rate Loans (such increases in costs and reductions in amounts
receivable, after taking into account such Lender's estimate, which shall be
conclusive if given in good faith, of the net tax benefit, if any, realized by
such Lender from such additional costs and reductions, being herein called
"Additional Costs"), resulting from any Regulatory Change after the Effective
Date which: (i) changes the basis of taxation of any amounts payable to such
Lender under this Agreement in respect of any of such Fixed Rate Loans (other
than taxes imposed on the overall net income of such Lender for any such Fixed
Rate Loans by the jurisdiction in which such Lender has its principal office)
or (ii) imposes or modifies (without duplication of any other amount required
to be paid hereunder) any reserve, special deposit, minimum capital, capital
ratio or similar requirements relating to the making by such Lender of any
Fixed Rate Loans (including any increase in cost to a Lender by reason of an
increase in any reserve requirement specified from time to time by the F.R.S.
Board and applicable to "Eurodollar Liabilities" as defined in Regulation D of
the F.R.S. Board or other similar reserve requirements affecting Eurodollar
deposits).  Such Lender shall promptly notify the Agent and the Borrower in
writing of the occurrence of any such event, such notice to state, in
reasonable detail, the reasons therefor and the Additional Costs.  Such
Additional Costs shall be payable by the





                                       40
<PAGE>
Borrower directly to such Lender within thirty days of the Borrower's receipt
of such notice, and such notice shall, in the absence of manifest error, be
conclusive and binding on the Borrower.

       SECTION 4.4.  Funding Losses.  In the event any Lender shall incur any
loss or reasonable expense (including any loss or expense incurred by reason of
the liquidation or reemployment of deposits or other funds acquired by such
Lender to make, continue or maintain any portion of the principal amount of any
Loan as, or to convert any portion of the principal amount of any Loan into, a
Fixed Rate Loan) as a result of

              (a)    any conversion or repayment or prepayment of the principal
       amount of any Fixed Rate Loans on a date other than the scheduled last
       day of the Interest Period applicable thereto, whether pursuant to
       Section 3.1 or otherwise;

              (b)    any Loans not being made as Fixed Rate Loans in accordance
       with the Borrowing Request therefor; or

              (c)    any Loans not being continued as, or converted into, Fixed
       Rate Loans in accordance with the Continuation/ Conversion Notice
       therefor,

then, upon the written notice of such Lender to the Borrower (with a copy to
the Agent), the Borrower shall, within thirty days of its receipt thereof, pay
directly to such Lender such amount as will (in the reasonable determination of
such Lender) reimburse such Lender for such loss or expense, provided that, the
Borrower shall not be liable to a Lender hereunder for any such loss or expense
incurred by such Lender as a result of such Lender's gross negligence or wilful
misconduct, breach of this Agreement or failure to comply with a Borrowing
Request or Continuation/ Conversion Notice.  Such written notice (which shall
include calculations in reasonable detail) shall, in the absence of manifest
error, be conclusive and, if made in good faith, binding on the Borrower.

       SECTION 4.5.  Increased Capital Costs.  Without duplication of any other
provision of this Article IV, if any Regulatory Change after the Effective Date
affects the amount of capital required to be maintained by any Lender or any
Person controlling such Lender, and such Lender determines (in its sole and
absolute discretion) that the rate of return on its or such controlling
Person's capital as a consequence of its Commitments or the Loans made by such
Lender is reduced as a result of such Regulatory Change to a level below that
which such Lender or such controlling Person could have achieved but for the
occurrence of such Regulatory Change, then, in any such case upon notice from
time to time by such Lender to the Borrower, the Borrower shall within thirty
days pay directly to such Lender additional amounts (after taking into account
such Lender's estimates, which shall be conclusive if made in good faith, of
the net tax benefit, if any, realized by such Lender resulting from such
Regulatory Change) sufficient to compensate such Lender or such controlling
Person for such reduction in rate of return.  A statement of such Lender as to
any such additional amount or amounts (including calculations thereof in
reasonable detail) shall, in the absence of manifest error, be conclusive and,
if made in good faith, binding on the Borrower.  In determining such amount,
such





                                       41
<PAGE>
Lender may use any method of averaging and attribution that it (in its sole and
absolute discretion) shall deem applicable.

       SECTION 4.6.  Period of Liability.  The Borrower shall not be liable to
any Lender pursuant to Section 4.3, 4.4, or 4.5 in respect of such compensation
for any period commencing more than one year before the delivery of any notice
pursuant to Sections 4.3, 4.4, or 4.5 except that the Borrower may be liable
for an earlier period if the Regulatory Change resulting in such notice shall
have been given retroactive effect affecting any period beginning more than 365
days prior to such notice.

       SECTION 4.7.  Taxes.  All payments by the Borrower of principal of, and
interest on, the Loans and all other amounts payable hereunder shall be made
free and clear of and without deduction for any present or future income, stamp
or other taxes, fees, duties, withholdings or other charges of any nature
whatsoever imposed by any taxing authority, other than taxes imposed on or
measured by any Lender's net income or receipts and franchise taxes (such non-
excluded items being called "Taxes").  In the event that any withholding or
deduction from any payment to be made by the Borrower hereunder is required in
respect of any Taxes pursuant to any applicable law, rule or regulation, then
the Borrower will

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

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

              (c)    pay to the Agent for the account of the Lenders such
       additional amount or amounts as is necessary to ensure that the net
       amount actually received by each Lender will equal the full amount such
       Lender would have received had no such withholding or deduction been
       required.

Upon the request of the Borrower, each Lender and each subsequent holder of any
Note that is organized under the laws of a jurisdiction other than the U.S.
shall, prior to the due date of any payments under the Notes, execute and
deliver to the Borrower, on or about the first scheduled payment date in each
Fiscal Year, a United States Internal Revenue Service Form 4224 or Form 1001,
as may be applicable (or any successor form), appropriately completed.  Without
prejudice to the survival of any other agreement of the Borrower hereunder or
any other Loan Document, the agreements of the Borrower contained in this
Section shall survive the payment in full of all its Obligations.

       SECTION 4.8.  Payments, Computations, etc.  Unless otherwise expressly
provided, all payments by the Borrower pursuant to this Agreement, the Notes or
any other Loan Document shall be made by the Borrower to the Agent for the pro
rata account of the Lenders entitled to receive such payment.  The Borrower
shall make each payment required to be made to the Agent not later than 11:00
a.m., United States Central time, on the date due, in same day or immediately
available funds,





                                       42
<PAGE>
to such account as the Agent shall specify from time to time by notice to the
Borrower.  Funds received after that time shall be deemed to have been received
by the Agent on the next succeeding Business Day.  The Agent shall promptly
remit in same day funds to each Lender its share, if any, of such payments
received by the Agent for the account of such Lender.  All interest on Fixed
Rate Loans and all fees shall be computed on the basis of the actual number of
days (including the first day but excluding the last day) occurring during the
period for which such interest or fee is payable over a year comprised of 360
days and in the case of interest on a Prime Rate Loan, 365 days or, if
appropriate, 366 days.  Whenever any payment to be made shall otherwise be due
on a day which is not a Business Day, such payment shall be made on the next
succeeding Business Day and such extension of time shall be included in
computing interest, if any, in connection with such payment.

       SECTION 4.9.  Sharing of Payments.  If any Lender shall obtain any
payment or other recovery (whether voluntary, involuntary, by application of
setoff or otherwise) on account of any Loan (other than pursuant to the terms
of Sections 4.3, 4.4 and 4.5 ) in excess of its pro rata share of payments then
or therewith obtained by all Lenders, such Lender shall purchase from the other
Lenders such participations in Loans made by them as shall be necessary to
cause such purchasing Lender to share the excess payment or other recovery
ratably with each of them; provided, however, that if all or any portion of the
excess payment or other recovery is thereafter recovered from such purchasing
Lender, the purchase shall be rescinded and each Lender which has sold a
participation to the purchasing Lender shall repay to the purchasing Lender the
purchase price to the ratable extent of such recovery together with an amount
equal to such selling Lender's ratable share (according to the proportion of
(a) the amount of such selling Lender's required repayment to the purchasing
Lender to  (b)       the total amount so recovered from the purchasing Lender)
of any interest or other amount paid or payable by the purchasing Lender in
respect of the total amount so recovered.  The Borrower agrees that any Lender
so purchasing a participation from another Lender pursuant to this Section may,
to the fullest extent permitted by law, exercise all its rights of payment
(including pursuant to Section 4.10) with respect to such participation as
fully as if such Lender were the direct creditor of the Borrower in the amount
of such participation.  If under any applicable bankruptcy, insolvency or other
similar law, any Lender receives a secured claim in lieu of a setoff to which
this Section applies, such Lender shall, to the extent practicable, exercise
its rights in respect of such secured claim in a manner consistent with the
rights of the Lenders entitled under this Section to share in the benefits of
any recovery on such secured claim.

       SECTION 4.10. Setoff.  Each Lender shall, upon the occurrence of any
Default described in clauses (a) through (d) of Section 9.1.9 with respect to
the Borrower or any Subsidiary or, upon the occurrence of any other Event of
Default, have the right to appropriate and apply to the payment of the
Obligations owing to it (whether or not then due), and (as security for such
Obligations) the Borrower hereby grants to each Lender a continuing security
interest in, any and all balances, credits, deposits, accounts or moneys of the
Borrower then or thereafter maintained with such Lender; provided, however,
that any such appropriation and application shall be subject to the provisions
of Section 4.9.  Each Lender agrees promptly to notify the Borrower and the
Agent after any such setoff and application made by such Lender; provided,
however, that the failure to give such notice shall not affect the validity of
such setoff and application.  The rights of each Lender under this Section





                                       43
<PAGE>
are in addition to other rights and remedies (including other rights of setoff
under applicable law or otherwise) which such Lender may have.

       SECTION 4.11. Use of Proceeds.  The Borrower shall apply the proceeds of
each Borrowing in accordance with the sixth recital; without limiting the
foregoing, and except as permitted by Section 8.5(d), no proceeds of any Loan
will be used to acquire any equity security of a class which is registered
pursuant to Section 12 of the Securities Exchange Act of 1934 if such
acquisition would result in the Borrower's owning more than five percent (5%)
of the issuer's outstanding voting stock and no proceeds of any Loan will be
used to acquire such stock if such acquisition would result in any violation of
F.R.S. Board Regulation U by the Borrower or the Lender.

Borrowing Request for such Borrowing.  Each of the delivery of a Borrowing
Request and the acceptance by the Borrower of the proceeds of such Borrowing

                         REPRESENTATIONS AND WARRANTIES

       In order to induce the Lenders and the Agent to enter into this

                                       47
<PAGE>
or limited liability company where the nature of its business requires such
qualification, except where failure to qualify would not have a material
adverse effect on the business or financial condition of the Borrower, or the
Borrower and its Subsidiaries taken as a whole or the Borrower's ability to
perform under the Loan Documents.  The Borrower and each of its Subsidiaries
has full corporate, partnership or limited liability company, as the case may
be, power and authority and holds all requisite governmental licenses, permits
and other approvals to enter into and perform its Obligations under this
Agreement, the Notes and each other Loan Document and to own and hold under
lease its property and to conduct its business substantially as currently

       SECTION 6.2.  Due Authorization, Non-Contravention, etc.  The execution,
delivery and performance by the Borrower or any Subsidiary of this Agreement,
the Notes and each other Loan Document executed or to be executed by it, are
within the Borrower's or the Subsidiary's corporate,  partnership or limited
liability company powers, as the case may be, have been duly authorized by all
necessary corporate, partnership or limited liability company action, as the
case may be, and do not

              (a)    contravene the Borrower's or such Subsidiary's Organic
       Documents, partnership agreement, or other similar governing agreements,
       as the case may be;

              (b)    contravene any contractual restriction, law or
       governmental regulation or court decree or order binding on or affecting
       the Borrower or any Subsidiary; or

"holding company", or an "affiliate" of a "holding company" or of a "subsidiary
company" of a "holding company", within the meaning of the Public Utility

       SECTION 6.4.  Validity, etc.  This Agreement constitutes, and the Notes
and each other Loan Document executed by the Borrower or any Subsidiary will,
on the due execution and delivery thereof, constitute, the legal, valid and
binding obligations of the Borrower or such Subsidiary, as the case may be,
enforceable in accordance with their respective terms except as such
enforceability is subject to the effect of (i) any applicable bankruptcy,
insolvency, reorganization or similar law relating to or affecting creditors'
rights generally and (ii) general principles of equity (regardless of whether
such enforceability is considered in a proceeding in equity or at law),
including concepts of materiality, reasonableness, good faith and fair dealing.

consequences that would materially adversely affect the financial condition,
operations, assets, business, properties or prospects of the Borrower, or of
the Borrower and any Subsidiaries and Affiliates taken as a whole, except as
disclosed in the Borrower's most recent Form 10-K or 10-Q filed with the S.E.C.

in default with respect to any judgment, order, writ, injunction, decree, rule
or regulation of any court or Federal, state, municipal or other governmental

       the amount of issued and outstanding shares of capital stock of each
       such corporate Subsidiary which is identified in Item 6.8(a) of the

       rights granted in connection





                                       49
<PAGE>
       with the issuance of any such shares.  All such shares are duly issued,
       fully paid and nonassessable and there are no outstanding options,
       warrants or other rights entitling the holder thereof to purchase any
       shares of capital stock of any such Subsidiary except as disclosed in
       Item 6.8(a) of the Disclosure Schedule.  The Borrower's partnership or

properties and assets and all revenues (present and future) of the Borrower and
its Subsidiaries are free and clear of all Liens, charges or claims (including

month period prior to the date of the execution and delivery of this Agreement
and prior to the date of any Borrowing hereunder, no steps have been taken to
terminate any Pension Plan, and no contribution failure has occurred with
respect to any Pension Plan sufficient to give rise to a Lien under section
302(f) of ERISA.  No condition exists or event or transaction has occurred with
respect to any Pension Plan which might result in the incurrence by the
Borrower or any member of the Controlled Group of any material liability, fine
or penalty.  Except as disclosed in Item 6.11 ("Employee Benefit Plans") of the
Disclosure Schedule, neither the Borrower nor any member of the Controlled
Group has any contingent liability with respect to any post-retirement benefit

       businesses;

              (e)    no property now or previously owned, leased or operated by
       the Borrower or any of its Subsidiaries is listed or proposed for
       listing (with respect to owned property only) on the National Priorities
       List pursuant to CERCLA, on the CERCLIS or on any similar state list of

       Priorities List pursuant to CERCLA, on the CERCLIS or on any similar
       state list or a site which currently is the subject of federal, state or
       local enforcement actions or other investigations which may lead to
       claims against the Borrower or such Subsidiary thereof for





                                       51
<PAGE>

       liability would have a material adverse effect on the financial
       condition, operations, assets, business, properties or prospects of the
       Borrower and its Subsidiaries taken as a whole.

       SECTION 6.13. Regulations G, T, U and X.  The Borrower is not engaged in
the business of extending credit for the purpose of purchasing or carrying
margin stock, and no proceeds of any Loans will be used for a purpose which
violates, or would be inconsistent with, F.R.S. Board Regulation G, T, U or X.
Terms for which meanings are provided in F.R.S. Board Regulation G, T, U or X
or any regulations substituted therefor, as from time to time in effect, are
used in this Section with such meanings.

       SECTION 6.14. Rank of Indebtedness.  The obligations of the Borrower to

all other amounts payable by the Borrower hereunder constitute direct and

or other obligations arising out of the extension of credit, of the Borrower.
As of March 31, 1997, the Borrower does not have outstanding any such liability
or obligation which is subordinated to any other such indebtedness, liability
or obligation but which is not subordinated to all indebtedness of the Borrower
for money borrowed hereunder and under the Notes.  Except as disclosed in the
notes to the financial statements filed with the Borrower's Form 10-Q for the

       SECTION 6.16. Accuracy of Information.  As of March 31, 1997, the
Borrower has no Indebtedness except as disclosed in Item 6.16 ("Ongoing
Indebtedness") of the Disclosure Schedule,





                                       52
<PAGE>
which Disclosure Schedule includes all Indebtedness reported in the Borrower's
most recent Form 10-K or 10-Q filed with the S.E.C.  Since May 31, 1997, there
have been, as of the date of this Agreement, no material increases in the
respective outstanding amounts of or (except for Trade Indebtedness and other
permitted Senior Debt) changes in the terms or conditions of such Indebtedness.
All factual information heretofore or contemporaneously furnished by or on
behalf of the Borrower in writing to the Agent or any Lender for purposes of or
in connection with this Agreement or any transaction contemplated hereby is,
and all other such factual information hereafter furnished by or on behalf of
the Borrower to the Agent or any Lender for purposes of or in connection with
this Agreement will be, true and accurate in every material respect on the date
as of which such information is dated or certified, and such information does
not, or shall not, as the case may be, omit to state any material fact
necessary to make such information not misleading.

       SECTION 6.17. No Contractual Violation.  Borrower has no contract or
agreement to which it or any of its Subsidiaries is a party or by which it or
its properties are bound (excluding any agreements or contracts governing
Indebtedness that do not exceed $1,000,000 at any one time outstanding in the
aggregate which have been incurred to vendors to finance acquisition of assets
as to the assets financed with such Indebtedness) prohibiting or having the
effect of prohibiting the creation or assumption of any Lien upon any of its
assets, properties or revenues whether now owned or hereafter acquired, or
restricting the ability of the Borrower to amend or otherwise modify this
Agreement or any other Loan Document, except as provided in this Agreement and
the other Loan Documents.

       together with a certificate from such accountants containing a
       computation of, and showing compliance with, each of the financial
       ratios and restrictions contained in Section 8.4 and to the effect that,
       in making the examination necessary for the signing of such annual
       report by such accountants, they have not become aware of any Default or

       become aware of such Default or Event of Default, describing such
       Default or Event of Default and the steps, if any, being taken to cure
       it; provided that, if such accountants' opinion contains an
       Impermissible Qualification, the Borrower must satisfy the Agent and the
       Required Lenders that the Impermissible Qualification does not reflect a
       condition that materially impairs the timely collectibility by the
       Lenders of any monetary Obligations then outstanding;

       Borrower has fulfilled all of its obligations under this Agreement and
       the Notes and any other Loan Document to which it is a party and that to
       the best of his knowledge (A) no Default has occurred, or if any such
       Default has occurred, specifying the nature and extent thereof and the
       nature of any corrective action taken or proposed to be taken to cure
       such Default, (B) the Borrower has fulfilled all its obligations under

       Borrowing Base Properties could not, as of the end of such Fiscal
       Quarter, make any of representations or warranties made by a Subsidiary
       of the Borrower which is set forth in Sections 6.1, 6.9, 6.10 and 6.12;

                     (ii)   make any payment or prepayment of principal of any
              Subordinated Indebtedness which would violate the subordination
              provisions of such Subordinated Indebtedness; or

                     (iii)  make any payment or prepayment of interest on any
              Subordinated Indebtedness, other than payments or prepayments of
              interest in connection with any payment, prepayment, redemption,
              purchase or defeasance permitted under Section 8.6(b)(i), on any
              day prior to the stated scheduled date for such payment or
              prepayment set forth in the documents memorializing such
              Subordinated Indebtedness, or which would violate the
              subordination provisions of such Subordinated Indebtedness;

              (c)    the Borrower will not, and will not permit any Subsidiary
       to, make any deposit for any of the foregoing prohibited purposes and no
       payment, dividend, distribution, prepayment, redemption, purchase or
       defeasance otherwise permitted by clause (a) or (b) shall be permitted
       to be made if, immediately before or after giving effect thereto, any
       Default shall have occurred and be continuing provided that, in
       determining if any Default pursuant to Section 8.4 shall have occurred
       or is continuing immediately before or after such payment, dividend,
       distribution, prepayment, redemption, purchase or defeasance, the
       Borrower may rely on financial information available to it since the
       date of the financial statements most recently delivered by it pursuant
       to Sections 7.2(a) and 7.2(b); and

              (d)    the Borrower will not permit any Subsidiary or Affiliate
       owning Borrowing Base Properties to enter into any agreement which
       restricts such Subsidiary or Affiliate from  (i) dividending the
       Borrower's, or its share owning Subsidiary's, share of net profits to
       the Borrower or such share owning Subsidiary  or (ii) making payments of
       principal or interest on any loan  from the Borrower, a Subsidiary or an
       Affiliate unless (x) prior thereto, such Subsidiary or Affiliate
       executes and delivers a valid and enforceable Subsidiary Guarantee to
       the Lenders or (y)  contemporaneously therewith, the Required Lenders
       consent to such Subsidiary or Affiliate entering into such agreement;
       provided that in connection with such consent, the Required Lenders may
       require an immediate redetermination of the Borrowing Base in connection
       therewith.

       SECTION 8.7.  Consolidation, Merger, etc.  The Borrower will not, and
will not permit any of its Subsidiaries or B8/32 Partners to, liquidate, wind
up or dissolve, consolidate with, or merge





                                       64
<PAGE>
into or with, any other corporation, or purchase or otherwise acquire all or
substantially all of the assets of any Person (or of any division thereof)
except as set forth below and so long as the Borrower (if the Borrower is a
party thereto) is the surviving entity:

              (a)    any such Subsidiary may liquidate or dissolve voluntarily
       into, and may consolidate or merge with and into, the Borrower or any
       other Subsidiary;

              (b)    B8/32 Partners may liquidate or dissolve voluntarily into,
       and may merge with and into, the Borrower, any Subsidiary or any other
       Person; provided, that, either (i) the Borrower's equity interest in the
       surviving Person (in the case of a dissolution into, or consolidation or
       merger with and into a Person other than the Borrower or a Subsidiary)
       is equal to its equity interest in B8/32 Partners immediately prior to
       such dissolution, consolidation or merger or (ii) all of the Borrowing
       Base Properties, or the proceeds upon liquidation thereof, become the
       property of the Borrower or a Subsidiary; and

              (c)    so long as no Default has occurred and is continuing or
       would occur after giving effect thereto, the Borrower or any of its
       Subsidiaries may purchase all or substantially all of the assets of any
       Person (other than the Borrower), or acquire such Person (other than the
       Borrower) by merger.

       SECTION 8.8.  Asset Dispositions.  The Borrowing Base may be
redetermined if, in either of the first half or second half of any Fiscal Year:


              (a)    the aggregate value of assets (including cash accounts,
       accounts receivable, production payments, and capital stock of or
       partnership interests in Subsidiaries, but excluding oil, gas, and other
       liquid or gaseous hydrocarbons sold in the ordinary course of business)
       sold, transferred, leased, contributed, or otherwise conveyed by the
       Borrower and its Subsidiaries other than to the Borrower or its
       Subsidiaries, or to which the Borrower and its Subsidiaries may grant
       options, warrants, or other rights, shall exceed, in the aggregate,
       $10,000,000.  Notwithstanding the foregoing, the Borrower and its
       Subsidiaries may grant, sell, or convey production payments as permitted
       by this Agreement in connection with Non-Recourse Indebtedness.  For
       purposes of this Section 8.8(a), the value of any asset is the greater
       of its book value or fair market value at the time of any disposition;
       and

              (b)    the Discounted Present Value of Borrowing Base Properties
       sold, transferred, leased, contributed or otherwise conveyed by the
       Borrower to any Subsidiary shall exceed, in the aggregate, ten percent
       (10%) of the Borrowing Base determined pursuant to the most recent
       Reserve Reports or Alternate Reserve Reports without first obtaining the
       consent of the Required Lenders, which consent shall not be unreasonably
       withheld and shall not require the payment of a fee or other
       compensation by the Borrower.

       SECTION 8.9.  Modification of Certain Agreements.  The Borrower will not
consent to any amendment, supplement or other modification of any of the terms
or provisions contained in, or





                                       65
<PAGE>
applicable to any document or instrument evidencing or governing any existing
Subordinated Indebtedness, other than any amendment, supplement or other
modification which (a)  does not accelerate the date of or increase the amount
of any repayment or redemption required pursuant to such agreements, prior to
July 2, 2002, (b) does not contain covenants regarding the matters set forth in
Section 8.4 materially more restrictive than the covenants contained in Section
8.4 of this Agreement, (c) does not increase the rate of interest payable or
fees and other compensation, except to the extent such fees and other
compensation are usual and customary for transactions of such type, and (d)
does not contain or result in subordination terms materially less favorable to
holders of the Notes than the original terms.  After giving effect to any
amendment, supplement, or modification which conforms to clauses (a), (b), (c),
and (d) of this Section 8.9, the Indebtedness of the Borrower shall not exceed
the limits permitted pursuant to clause (a) of Section 8.4.

       SECTION 8.10. Transactions with Affiliates.  The Borrower will not, and
will not permit any of its Subsidiaries to, enter into, or cause, suffer or
permit to exist any arrangement or contract with any of its other Affiliates
unless such arrangement, as of the date it was entered into, is fair and
equitable to the Borrower or such Subsidiary and is (as of such date) not of a
sort which would not be entered into by a prudent Person in the position of the
Borrower or such Subsidiary with, or which is on terms which are less favorable
than are obtainable from, any Person which is not one of its Affiliates.

       SECTION 8.11. [Intentionally Omitted].

       SECTION 8.12. Negative Pledges, etc.  The Borrower will not, and will
not permit any of its Subsidiaries to, enter into any agreement (excluding this
Agreement, any other Loan Document, any agreement related to Indebtedness
permitted under Sections 8.2(a)(ii) and 8.2(a)(iii), and any agreement
governing Indebtedness not to exceed $1,000,000 at any one time outstanding in
the aggregate which is incurred to vendors to finance acquisitions of assets as
to the assets financed with proceeds of such Indebtedness) prohibiting or
having the effect of prohibiting the creation or assumption of any Lien upon
any of its properties, revenues or assets, whether now owned or hereafter
acquired, or restricting the ability of the Borrower to amend or otherwise
modify this Agreement or any other Loan Document.


                                   ARTICLE IX

default in the payment or prepayment, including any mandatory prepayment
pursuant to Section 3.1.2. or 3.1.3, when due of any principal of any Loan, or
the Borrower shall default (and such default shall continue





                                       66
<PAGE>
unremedied for a period of five days) in the payment when due of interest on
any Loan, any Commitment Fee or other fee provided for in this Agreement or of
any other Obligation.

       SECTION 9.1.2. Breach of Warranty.  Any representation or warranty of 
the Borrower or any Subsidiary made or deemed to be made hereunder or in any

behalf of the Borrower (including any certificate delivered pursuant to Article
VII) to the Agent or any Lender for the purposes of or in connection with this

pursuant to Article V) is or shall be incorrect when made in any material
respect.

       SECTION 9.1.3. Non-Performance of Certain Covenants and Obligations.  
The Borrower shall default in the due performance and observance of any of its
obligations under Article VIII (excluding Section 8.4) and, with respect to
Section 8.3, 8.5 or 8.6, such default shall continue unremedied for a period of
five (5) Business Days after notice thereof shall have been given to the
Borrower by the Agent or any Lender.

       SECTION 9.1.4. Non-Performance of Other Covenants and Obligations. The 
Borrower or any Subsidiary shall default in the due performance and observance

Borrower or any of its Subsidiaries, or a default shall occur in the performance
or observance of any obligation or condition with respect to such Indebtedness
if the effect of such default is to accelerate the maturity of any such
Indebtedness or to permit the holder or holders thereof, or any trustee or agent
for such holders, to cause such Indebtedness to become due and payable prior to
its expressed maturity.

       SECTION 9.1.6. Judgments.  Any judgments or orders for the payment of 
money which are, in aggregate, in excess of $10,000,000 at any one time
outstanding shall be rendered against the Borrower or any of its Subsidiaries
and the same shall remain undischarged and either

       creditor upon such judgment or order; or

              (b)    there shall be any period of 30 consecutive days during
       which a stay of enforcement of such judgment or order, by reason of a
       pending appeal or otherwise, shall not be in effect.

occur with respect to any Pension Plan

              (a)    the institution of any steps by the Borrower, any member

       Plan, in excess of $1,000,000; or

              (b)    a contribution failure occurs with respect to any Pension
       Plan sufficient to give rise to a Lien under Section 302(f) of ERISA.

       or liquidation proceeding (except the voluntary dissolution, not under
       any bankruptcy or insolvency law, of a Subsidiary pursuant to Section
       8.7), in respect of the Borrower or any of its Subsidiaries, and, if any
       such case or proceeding is not commenced by the Borrower or such
       Subsidiary, such case or proceeding shall be consented to or acquiesced
       in by the Borrower or such Subsidiary or shall result in the entry of an
       order for relief or shall remain for 60 days undismissed; or

                                       68
<PAGE>
and all other Obligations shall automatically be and become immediately due and
payable, without notice or demand.

       SECTION 9.3.  Action if Other Event of Default.  If any Event of Default
(other than any Event of Default described in clauses (a) through (d) of
Section 9.1.9) shall occur for any reason, whether voluntary or involuntary,
and be continuing, the Agent, upon the direction of the Required Lenders, shall
by notice to the Borrower declare the outstanding principal amount of the Loans

of such Loans and other Obligations which shall be so declared due and payable
shall be and become immediately due and payable, without further notice, demand
or presentment.


                                   ARTICLE X

                           THE AGENT AND THE CO-AGENT

       SECTION 10.1. Actions.  Each Lender hereby appoints the Agent as its
agent under and for purposes of this Agreement, the Notes and each other Loan
Document.  Each Lender authorizes the Agent to act on behalf of such Lender
under this Agreement, the Notes and each other Loan Document and, in the
absence of other written instructions from the Required Lenders received from
time to time by the Agent (with respect to which the Agent agrees that it will
comply, except as otherwise provided in this Section or as otherwise advised by
counsel), to exercise such powers hereunder and thereunder as are specifically
delegated to or required of the Agent by the terms hereof and thereof, together
with such powers as may be reasonably incidental thereto.  Each Lender hereby
indemnifies (which indemnity shall survive any termination of this Agreement)
each of the Agent and the Co-Agent, pro rata according to such Lender's
Percentage, from and against any and all liabilities, obligations, losses,
damages, claims, costs or expenses of any kind or nature whatsoever which may
at any time be imposed on, incurred by, or asserted against, the Agent and the
Co-Agent in any way relating to or arising out of this Agreement, the Notes and
any other Loan Document, including reasonable attorneys' fees, and as to which
the Agent or Co-Agent is not reimbursed by the Borrower; provided, however,
that no Lender shall be liable for the payment of any portion of such
liabilities, obligations, losses, damages, claims, costs or expenses which are
determined by a court of competent jurisdiction in a final proceeding to have
resulted solely from the Agent's or the Co-Agent's gross negligence or wilful
misconduct.  Neither the Agent nor the Co-Agent shall be required to take any
action hereunder, under the Notes or under any other Loan Document, or to
prosecute or defend any suit in respect of this Agreement, the Notes or any
other Loan Document, unless it is indemnified hereunder to its satisfaction.
If any indemnity in favor of the Agent or the Co-Agent shall be or become, in
the Agent's or the Co-Agent's determination, inadequate, the Agent or the
Co-Agent may call for additional indemnification from the Lenders and cease to
do the acts indemnified against hereunder until such additional indemnity is
given.

       SECTION 10.2. Funding Reliance, etc.  Unless the Agent shall have been
notified by telephone, confirmed in writing, by any Lender by 5:00 p.m., United
States Central time on the day





                                       69
<PAGE>
prior to a Borrowing in the case of Fixed Rate Loans, or by 11:00 a.m. U.S.
Central time on the day of any Borrowing in the case of Prime Rate Loans, that
such Lender will not make available the amount which would constitute its
Percentage of such Borrowing on the date specified therefor, the Agent may
assume that such Lender has made such amount available to the Agent and, in
reliance upon such assumption, make available to the Borrower a corresponding
amount.  If and to the extent that such Lender shall not have made such amount
available to the Agent, such Lender and the Borrower severally agree to repay
the Agent forthwith on demand such corresponding amount together with interest
thereon, for each day from the date the Agent made such amount available to the
Borrower to the date such amount is repaid to the Agent, at the Federal Funds
Rate at that time.

       SECTION 10.3. Exculpation.  Neither the Agent, the Co-Agent nor any of
their directors, officers, employees or agents shall be liable to any Lender
for any action taken or omitted to be taken by it under this Agreement or any
other Loan Document, or in connection herewith or therewith, except for their
own wilful misconduct or gross negligence, nor responsible for any recitals or
warranties herein or therein, nor for the effectiveness, enforceability,
validity or due execution of this Agreement or any other Loan Document, nor to
make any inquiry respecting the performance by the Borrower of its obligations
hereunder or under any other Loan Document.  The Agent and the Co-Agent shall
each be entitled to rely upon advice of counsel concerning legal matters and
upon any notice, consent, certificate, statement or writing which the Agent or
the Co-Agent believes to be genuine and to have been presented by a proper
Person.

       SECTION 10.4. Successor.  The Agent may resign as such at any time upon
at least 30 days' prior notice to the Borrower and all Lenders.  If the Agent
at any time shall resign, the Required Lenders, with the consent of the
Borrower, may appoint another Lender or a commercial banking institution
organized under the laws of the U.S. (or any state thereof) or a U.S. branch or
agency of a commercial banking institution, and having a combined capital and
surplus of at least $500,000,000 as a successor Agent which shall thereupon
become the Agent hereunder.  If no successor Agent shall have been so appointed
by the Required Lenders, and shall have accepted such appointment, within 30
days after the retiring Agent's giving notice of resignation, then the retiring
Agent may, on behalf of the Lenders, appoint a successor Agent, which shall be
one of the Lenders or a commercial banking institution organized under the laws
of the U.S. (or any State thereof) or a U.S. branch or agency of a commercial
banking institution, and having a combined capital and surplus of at least
$500,000,000.  Upon the acceptance of any appointment as Agent hereunder by a
successor Agent, such successor Agent shall be entitled to receive from the
retiring Agent such documents of transfer and assignment as such successor
Agent may reasonably request, and shall thereupon succeed to and become vested
with all rights, powers, privileges and duties of the retiring Agent, and the
retiring Agent shall be discharged from its duties and obligations under this
Agreement.  After any retiring Agent's resignation hereunder as the Agent, the
provisions of

              (a)    this Article X shall inure to its benefit as to any
       actions taken or omitted to be taken by it while it was the Agent under
       this Agreement; and

              (b)    Section 11.3 shall continue to inure to its benefit.





                                       70
<PAGE>
       SECTION 10.5. Loans by the Agent and Banque Paribas.  Each of the Agent
and Banque Paribas shall have the same rights and powers with respect to (x)
the Loans made by it or any of its Affiliates, and (y) the Notes held by it or
any of its Affiliates as any other Lender and may exercise the same as if it
were not the Agent or Co-Agent, as the case may be.

       SECTION 10.6. Credit Decisions.  Each Lender acknowledges that it has,
independently of the Agent and each other Lender, and based on such Lender's
review of the financial information of the Borrower and such other documents,
information and investigations as such Lender has deemed appropriate, made its
own credit decision to extend its Commitments.  Each Lender also acknowledges
that it will, independently of the Agent and each other Lender, and based on
such other documents, information and investigations as it shall deem
appropriate at any time, continue to make its own credit decisions as to
exercising or not exercising from time to time any rights and privileges
available to it under this Agreement or any other Loan Document.

       SECTION 10.7. Copies, etc.  The Agent shall give prompt notice to each
Lender of each notice or request required or permitted to be given to the Agent
by the Borrower pursuant to the terms of this Agreement (unless concurrently
delivered to the Lenders by the Borrower).  The Agent will distribute to each
Lender each document or instrument received for its account and copies of all
other communications received by the Agent from the Borrower for distribution
to the Lenders by the Agent.


                                   ARTICLE XI

                            MISCELLANEOUS PROVISIONS

       SECTION 11.1. Waivers, Amendments, etc.  The provisions of this
Agreement and of each other Loan Document may from time to time be amended,
modified or waived, if such amendment, modification or waiver is in writing and
consented to by the Borrower and the Required Lenders; provided, however, that
no such amendment, modification or waiver which would:

              (a)    modify any requirement hereunder that any particular
       action be taken by all the Lenders or by the Required Lenders shall be
       effective unless consented to by each Lender;

              (b)    modify this Section 11.1, change the definition of
       "Required Lenders", increase any Commitment Amount or the Percentage of
       any Lender, change the definition of "Prime Rate" or "LIBO Rate" to
       reduce interest payable or the Applicable Margin by the Borrower, reduce
       any fees described in Article III, or extend any Commitment Termination
       Date shall be made without the consent of each Lender and each holder of
       a Note;

              (c)    extend the Stated Maturity Date for, or reduce the amount
       of, any scheduled repayment or any mandatory prepayment (whether
       pursuant to Section 3.1.2 or





                                       71
<PAGE>
       3.1.3 or otherwise) or of any interest payment due to any Lender on any
       Loan (or reduce the principal amount of or rate of interest on any Loan)
       shall be made without the consent of the holder of that Note evidencing
       such Loan; or

              (d)    affect adversely the interests, rights or obligations of
       the Agent qua the Agent, or the Co-Agent qua Co-Agent, shall be made
       without consent of the Agent or Co-Agent, as the case may be.

No failure or delay on the part of the Agent, any Lender or the holder of any
Note in exercising any power or right under this Agreement or any other Loan
Document shall operate as a waiver thereof, nor shall any single or partial
exercise of any such power or right preclude any other or further exercise
thereof or the exercise of any other power or right.  No notice to or demand on
the Borrower in any case shall entitle it to any notice or demand in similar or
other circumstances.  No waiver or approval by the Agent, any Lender or the
holder of any Note under this Agreement or any other Loan Document shall,
except as may be otherwise stated in such waiver or approval, be applicable to
subsequent transactions.  No waiver or approval hereunder shall require any
similar or dissimilar waiver or approval thereafter to be granted hereunder.

       SECTION 11.2. Notices.  All notices and other communications provided to
any party hereto under this Agreement or any other Loan Document shall be in
writing or by Telex or by facsimile and addressed, delivered or transmitted to
such party at its address, Telex or facsimile number set forth below its

       SECTION 11.3. Payment of Costs and Expenses.  The Borrower agrees to
promptly pay all reasonable expenses of each of the Agent and Co-Agent
(including the reasonable fees and out-of-pocket expenses of counsel to the
Agent or Co-Agent and of local counsel, if any, who may, following reasonable
notice to the Borrower, be retained by counsel to the Agent or Co-Agent) in
connection with

              (a)    the negotiation, preparation, execution and delivery of
       this Agreement and of each other Loan Document, including schedules and
       exhibits, and any amendments, waivers, consents, supplements or other
       modifications to this Agreement or any other Loan Document as may from
       time to time hereafter be required, whether or not the transactions
       contemplated hereby are consummated, and

              (b)    the preparation and review of the form of any document or
       instrument relevant to this Agreement or any other Loan Document.

The Borrower further agrees to pay, and to save the Agent and the Lenders
harmless from all liability for, any stamp or other taxes which may be payable
in connection with the execution or delivery of this Agreement, the borrowings
hereunder, or the issuance of the Notes or any other Loan Documents.  The
Borrower also agrees to reimburse the Agent and each Lender upon demand for all
reasonable out-of-pocket expenses (including attorneys' fees, which attorneys'
fees may include those of an attorney who is an employee of a Lender, and legal
expenses) incurred by the Agent or such Lender in connection with the
enforcement of any Obligations.

       SECTION 11.4. Indemnification.  In consideration of the execution and
delivery of this Agreement by each Lender and the extension of the Commitments,
the Borrower hereby indemnifies, exonerates and holds the Co-Agent and each
Agent, Lender and each of their respective officers, directors, employees and
agents (collectively, the "Indemnified Parties") free and harmless from and
against any and all actions, causes of action, suits, losses, costs,
liabilities and damages, and expenses incurred in connection therewith
(irrespective of whether any such Indemnified Party is a party to the action
for which indemnification hereunder is sought), including reasonable attorneys'
fees and disbursements (collectively, the "Indemnified Liabilities"), incurred
by the Indemnified Parties or any of them as a result of, or arising out of, or
relating to

              (a)    any transaction financed or to be financed in whole or in
       part, directly or indirectly, with the proceeds of any Loan;

              (b)    the entering into and performance of this Agreement and
       any other Loan Document by any of the Indemnified Parties (including any
       action brought by or on behalf of the Borrower as the result of any
       determination by the Required Lenders pursuant to Article V not to fund
       any Borrowing);

              (c)    any investigation, litigation or proceeding related to any
       acquisition or proposed acquisition by the Borrower or any of its
       Subsidiaries of any portion of the stock or assets of any Person,
       whether or not the Agent or such Lender is party thereto;

              (d)    any investigation, litigation or proceeding related to any
       environmental cleanup, audit, compliance or other matter relating to the
       protection of the environment or the Release by the Borrower or any of
       its Subsidiaries of any Hazardous Material; or

              (e)    the presence on or under, or the escape, seepage, leakage,
       spillage, discharge, emission, discharging or releases from, any real
       property owned or operated by the Borrower or any Subsidiary thereof of
       any Hazardous Material (including any losses, liabilities, damages,
       injuries, costs, expenses or claims asserted or arising under any
       Environmental Law), regardless of whether caused by, or within the
       control of, the Borrower or such Subsidiary,

except for any such Indemnified Liabilities arising for the account of a
particular Indemnified Party by reason of the activities of the Indemnified
Party on the property of the Borrower conducted





                                       73
<PAGE>
subsequent to a foreclosure on such property by the Lenders or by reason of the
relevant Indemnified Party's gross negligence or wilful misconduct or breach of
this Agreement, and if and to the extent that the foregoing undertaking may be
unenforceable for any reason, the Borrower hereby agrees to make the maximum
contribution to the payment and satisfaction of each of the Indemnified
Liabilities which is permissible under applicable law.  The Borrower shall be
obligated to indemnify the Indemnified Parties for all Indemnified Liabilities
subject to and pursuant to the foregoing provisions, regardless of whether the
Borrower or any of its Subsidiaries had knowledge of the facts and
circumstances giving rise to such Indemnified Liability.

       Promptly after the receipt by an Indemnified Party of notice of the
commencement of any action to which the Borrower is not a party, such
Indemnified Party will, if a claim for indemnity in respect thereof is to be
made against the Borrower, notify the Borrower of the commencement thereof.  If
the Borrower will have acknowledged in writing that this Section 11.4 will
cover any Indemnified Liabilities in any such action, suit, proceeding or
investigation, and, in the sole determination of the Indemnified Party, the
Borrower has the financial ability to pay such Indemnified Liabilities, then
the Borrower will have the right, on behalf of such Indemnified Party, but at
the Borrower's expense, to defend such action, suit or proceeding, or
participate in such investigation, with counsel selected by it, and will have
sole discretion as to whether to litigate, appeal or settle.

       SECTION 11.5. Survival.  The obligations of the Borrower under Sections
4.3, 4.4, 4.5, 4.7, 11.3 and 11.4, and the obligations of the Lenders under
Section 10.1 and of the Agent and the Lenders under Section 11.12, shall in
each case survive any termination of this Agreement.  The representations and
warranties made by the Borrower in this Agreement and in each other Loan
Document shall survive the execution and delivery of this Agreement and each
such other Loan Document.

       SECTION 11.6. Severability.  Any provision of this Agreement or any
other Loan Document which is prohibited or unenforceable in any jurisdiction
shall, as to such provision and such jurisdiction, be ineffective to the extent
of such prohibition or unenforceability without invalidating the remaining
provisions of this Agreement or such Loan Document or affecting the validity or
enforceability of such provision in any other jurisdiction.

       SECTION 11.7. Headings.  The various headings of this Agreement and of
each other Loan Document are inserted for convenience only and shall not affect
the meaning or interpretation of this Agreement or such other Loan Document or
any provisions hereof or thereof.

       SECTION 11.8. Execution in Counterparts, Effectiveness, etc.  This
Agreement may be executed by the parties hereto in several counterparts, each
of which shall be deemed to be an original and all of which shall constitute
together but one and the same agreement.  This Agreement shall become effective
when counterparts hereof executed on behalf of the Borrower and each Lender (or
notice thereof satisfactory to the Agent) shall have been received by the Agent
and notice thereof shall have been given by the Agent to the Borrower and each
Lender.

       SECTION 11.9. Governing Law; Entire Agreement.  THIS AGREEMENT, THE
NOTES AND EACH OTHER LOAN DOCUMENT SHALL EACH BE DEEMED TO BE A CONTRACT MADE
UNDER AND GOVERNED BY THE INTERNAL LAWS OF THE STATE OF ILLINOIS.  This
Agreement, the Notes and the other Loan Documents constitute the entire
understanding among the parties hereto with respect to the subject matter
hereof and supersede any prior agreements, written or oral, with respect
thereto.

       THIS WRITTEN LOAN AGREEMENT REPRESENTS THE FINAL AGREEMENT BETWEEN THE
PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR
SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.

       THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

       SECTION 11.10. Successors and Assigns.  This Agreement shall be
binding upon and shall inure to the benefit of the parties hereto and their
respective successors and assigns; provided, however, that:

              (a)    the Borrower may not assign or transfer its rights or
       obligations hereunder without the prior written consent of the Agent and
       all Lenders; and

              (b)    the rights of sale, assignment and transfer of the Lenders
       are subject to Section 11.11.

       SECTION 11.11.       Sale and Transfer of Loans and Notes; Participations
in Loans and Notes.  Each Lender may assign, or sell participations in, its
Loans and Commitments to one or more other Persons in accordance with this
Section 11.11.

       SECTION 11.11.1.     Assignments.  Any Lender,

              (a)    with the written consents of the Borrower and the Agent
       (which consents shall not be unreasonably delayed or withheld and which
       consent, in the case of the Borrower, shall be deemed to have been given
       in the absence of a written notice delivered by the Borrower to the
       Agent, on or before the tenth Business Day after receipt by the Borrower
       of such Lender's request for consent, stating, in reasonable detail, the
       reasons why the Borrower proposes to withhold such consent) may at any
       time assign and delegate to one or more commercial banks or other
       financial institutions, each of which banks or institutions has capital
       and surplus and undivided profits of not less than $500,000,000, and

              (b)    with notice to the Borrower and the Agent, but without the
       consent of the Borrower or the Agent, may assign and delegate to any of
       its Affiliates or to any other Lender





                                       75
<PAGE>
(each Person described in either of the foregoing clauses as being the Person
to whom such assignment and delegation is to be made, being hereinafter
referred to as an "Assignee Lender"), all or any fraction of such Lender's
total Loans and Commitment (which assignment and delegation shall be of a
constant, and not a varying, percentage of all the assigning Lender's Loans and
Commitment) in a minimum aggregate amount for any Commitment equal to the
lesser of $5,000,000 or the Lender's entire Commitment; provided, however, that
any such Assignee Lender will comply with Section 11.12 and, if applicable,
with the provisions contained in the penultimate sentence of Section 4.7 and
further, provided, however, that, the Borrower and the Agent shall be entitled
to continue to deal solely and directly with such Lender in connection with the
interests so assigned and delegated to an Assignee Lender until

              (c)    written notice of such assignment and delegation, together
       with payment instructions, addresses and related information with
       respect to such Assignee Lender, shall have been given to the Borrower
       and the Agent by such Lender and such Assignee Lender,

              (d)    such Assignee Lender shall have executed and delivered to
       the Borrower and the Agent a Lender Assignment Agreement, accepted by
       the Agent, and

              (e)    the processing fees described below shall have been paid.

From and after the date that the Agent accepts such Lender Assignment Agreement
in accordance with the foregoing, (x) the Assignee Lender thereunder shall be
deemed automatically to have become a party hereto and to the extent that
rights and obligations hereunder have been assigned and delegated to such
Assignee Lender in connection with such Lender Assignment Agreement, shall have
the rights and obligations of a Lender hereunder and under the other Loan
Documents, and (y) the assignor Lender, to the extent that rights and
obligations hereunder have been assigned and delegated by it in connection with
such Lender Assignment Agreement, shall be released from its obligations
hereunder and under the other Loan Documents.  Within five Business Days after
its receipt of notice that the Agent has received an executed Lender Assignment
Agreement, the Borrower shall execute and deliver to the Agent (for delivery to
the relevant Assignee Lender) new Notes evidencing such Assignee Lender's
assigned Loans and Commitment and, if the assignor Lender has retained any
Loans and Commitment hereunder, replacement Notes in the principal amount of
the Loans and Commitment obligations retained by the assignor Lender hereunder
(such Notes to be in exchange for, but not in payment of, those Notes then held
by such assignor Lender).  Each such Note shall be dated the date of the
predecessor Notes.  The assignor Lender shall mark the predecessor Notes
"exchanged" and deliver them to the Borrower.  Accrued interest on that part of
the predecessor Notes evidenced by the new Notes, and accrued fees, shall be
paid as provided in the Lender Assignment Agreement.  Accrued interest on that
part of the predecessor Notes evidenced by the replacement Notes shall be paid
to the assignor Lender.  Accrued interest and accrued fees shall be paid at the
same time or times provided in the predecessor Notes and in this Agreement.
Such assignor Lender or such Assignee Lender must also pay a processing fee to
the Agent upon delivery of any Lender Assignment Agreement in the amount of
$2,000.  Any attempted assignment and delegation not made in accordance with
this Section 11.11.1 shall be null and void.





                                       76
<PAGE>
       SECTION 11.11.2.     Participations.  Any Lender may at any time sell to
one or more commercial banks or other Persons (each of such commercial banks
and other Persons being herein called a "Participant") participating interests
in any of the Loans, Commitments, or other interests of such Lender hereunder;
provided, however, that

              (a)    no participation contemplated in this Section 11.11 shall
       relieve such Lender from its Commitments or its other obligations
       hereunder or under any other Loan Document,

              (b)    such Lender shall remain solely responsible for the
       performance of its Commitment and such other obligations,

              (c)    the Borrower and the Agent shall continue to deal solely
       and directly with such Lender in connection with such Lender's rights
       and obligations under this Agreement and each of the other Loan
       Documents,

              (d)    no Participant, unless such Participant is an Affiliate of
       such Lender, or is itself a Lender, shall be entitled to require such
       Lender to take or refrain from taking any action hereunder or under any
       other Loan Document, except that such Lender may agree with any
       Participant that such Lender will not, without such Participant's
       consent, take any actions of the type described in clause (b) or (c) of
       Section 11.1, and

              (e)    no Participant shall be entitled to payment of any amount
       under Section 4.6 that would not have been required to be paid to such
       Lender had no participation occurred.

       The Borrower acknowledges and agrees that each Participant, for purposes
       of Sections 4.3, 4.4, 4.5, 4.9, 4.10, 11.3 and 11.4, shall be considered
       a Lender.

       SECTION 11.12.       Confidentiality.  The Lenders shall hold all
non-public information obtained pursuant to the requirements of this Agreement
in accordance with the Confidentiality Letters, and

              (a)    may not disclose or discuss such information with any
       other persons except that any Lender may disclose such information (i)
       to any bank regulatory authority at the request of such authority or in
       connection with an examination of such Lender by any such authority,
       (ii) pursuant to subpoena, other court process or as otherwise required
       by law, (iii) at the express direction of any other agency of any State
       of the United States, (iv) to such Lender's independent auditors,
       counsel or independent petroleum engineers retained by such Lender or
       (v) to any Assignee Lender or proposed Assignee Lender of all or any
       portion of any Lender's interests, rights and obligations under the
       Agreement and any participant or proposed participant in all or a
       portion of a Lender's obligations under the Agreement, in each case,
       only if such Assignee Lender or proposed Assignee Lender or participant
       or proposed





                                       77
<PAGE>
       participant shall execute and deliver to the Borrower prior to any
       disclosure of information or conclusions based on such information, a
       Confidentiality Letter.

              (b)    The obligation of confidentiality shall not apply to such
       portions of the information which the Lender establishes (i) are in the
       public domain, (ii) hereafter become part of the public domain without
       breach of this Section 11.12 or any Confidentiality Letter, (iii) are
       previously known from some source other than the Borrower, (iv) are
       developed without using the Borrower's information or (v) are hereafter
       obtained from a third party who owes no obligation of confidence to the
       Borrower with respect to such information.

              (c)    Unless prohibited by applicable law or court order, each
       Lender and the Agent will promptly notify the Borrower (in advance, if
       practicable) if it is required to disclose any such information or
       conclusions pursuant to clause (a)(ii) above.

              (d)    Each Lender and the Agent agree that it will not use any
       information obtained, inspected or reviewed by it in connection with the
       Agreement for the purpose of bidding, or in any manner advising or
       assisting in the bidding (including advising or assisting in advising in
       the nomination of tracts to be leased), on future lease sales of tracts
       in offset tracts or in drainage tracts to the Borrower's interests or
       for the purpose of purchasing, selling, offering to purchase or offering
       to sell, directly or indirectly, any equity securities of the Borrower
       (or assisting or advising others in connection therewith).

              (e)    All obligations of any Lender pursuant to this Section
       11.12 shall terminate on the second anniversary of the date on which all
       Obligations of the Borrower to such Lender under the Agreement and the
       Notes have been fulfilled.

              (f)    Each Lender and the Agent agree that it shall be
       responsible for the compliance with this Agreement by all its officers
       and employees to the same extent as if they were parties hereto.

       SECTION 11.13.       Other Transactions.  Nothing contained herein shall
preclude the Agent or any other Lender from engaging in any transaction, in
addition to those contemplated by this Agreement or any other Loan Document,
with the Borrower or any of its Affiliates in which the Borrower or such
Affiliate is not restricted hereby from engaging with any other Person.
