              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)

1.   RESPONSIBILITIES FOR FINANCIAL STATEMENTS

     The Condensed Consolidated Financial Statements of Union Pacific Resources
     Group Inc. and subsidiaries ("UPR" or the "Company") have been prepared by
     management, are unaudited and reflect all adjustments (including normal
     recurring adjustments) that are, in the opinion of management, necessary
     for a fair presentation of the financial position and operating results of
     the Company for the interim periods. However, these condensed statements do
     not include all of the information and footnotes required by generally
     accepted accounting principles to be included in a full set of financial
     statements. The report of Arthur Andersen LLP commenting on their review
     accompanies the Condensed Consolidated Financial Statements and is included
     in Part I, Item 1, in this report. The Condensed Consolidated Statement of
     Financial Position at December 31, 1999 is derived from audited financial
     statements. The Condensed Consolidated Financial Statements should be read
     in conjunction with the consolidated financial statements and notes thereto
     contained in the Company's Annual Report on Form 10-K for the year ended
     December 31, 1999. The results of operations for the three months ended
     March 31, 2000 are not necessarily indicative of the results for the full
     year ending December 31, 2000.

     The preparation of financial statements in conformity with generally
     accepted accounting principles requires management to make estimates and
     assumptions that affect the reported amounts of certain assets and
     liabilities, the disclosure of contingent assets and liabilities at the
     date of the financial statements and the reported amounts of revenues and
     expenses for each reporting period. Management believes its estimates and
     assumptions are reasonable; however, such estimates and assumptions are
     also subject to a number of risks and uncertainties which may cause actual
     results to differ materially.

4.   COMMITMENTS AND CONTINGENCIES

          The Company is subject to federal, state, provincial and local
     environmental laws and regulations and currently is participating in the
     investigation and remediation of a number of sites. Where the remediation
     costs can reasonably be determined, and where such remediation is probable,
     the Company has recorded a liability. The Company does not expect future
     environmental obligations to have a material impact on the consolidated
     results of operations, financial condition or cash flows of the Company.

          In connection with the disposition of significant plant, pipeline,
     refining and producing property assets, the Company has made certain
     representations and warranties related to the assets sold (covering, among
     other matters, the condition and capabilities of certain assets and
     compliance with environmental and other lawsuits) and provided certain
     indemnities with respect to liabilities associated with such assets. The
     Company has been advised of possible claims which may be asserted by the
     purchasers of certain disposed assets for alleged breaches of
     representations and warranties under certain indemnities. Certain claims
     related to compliance with environmental laws remain pending. In addition,
     as some of the representations, warranties and indemnities related to some
     of the disposed assets have not expired, further claims may be made against
     the Company. While no assurance can be given as to the ultimate outcome of
     these claims, the Company does not expect these matters to have a material
     adverse effect on its consolidated results of operations, financial
     condition or cash flows.

          The Company is a defendant in a number of lawsuits and is involved in
     governmental proceedings arising in the ordinary course of business,
     including but not limited to, royalty claims, contract claims and
     environmental claims. The Company has also been named as a defendant in
     various personal injury claims, including numerous claims by employees of
     third party contractors alleging exposure to asbestos and asbestos
     containing materials while working at the Corpus Christi refinery, which
     the Company sold in segments in 1987 and 1989. The Company also has entered
     into commitments and provided guarantees for specific financial and
     contractual obligations of its subsidiaries and affiliates. While the
     Company's management cannot predict the outcome of any litigation and other
     proceedings, the Company does not expect these lawsuits, commitments or
     guarantees to have a material adverse effect on the consolidated results of
     operations, financial condition or cash flows of the Company.

5.   DEBT

          During the first quarter 2000, the Company purchased on the open
     market and retired long-term debt with a face value of $100.0 million at a
     discount prior to maturity. The retirement of long-term debt due to the
     repurchases resulted in an extraordinary gain of $2.9 million, net of $1.5
     million of tax. The gain on the retirement was classified as a gain from an
     extraordinary item on the Condensed Consolidated Statement of Income.
     Additionally, during the first quarter 2000, the Company repaid $90.4
     million of Bankers' Acceptances.

6.   SUBSEQUENT EVENTS

          On April 2, 2000, UPR, Anadarko Petroleum Corporation, a Delaware
     corporation ("Anadarko"), and Dakota Merger Corp., a Utah corporation and
     wholly-owned subsidiary of Anadarko ("Subcorp"), entered into an Agreement
     and Plan of Merger, dated as of April 2, 2000 (the "Merger Agreement"),
     pursuant to which Subcorp will merge with and into UPR, and UPR will become
     a wholly-owned subsidiary of Anadarko. Under the Merger Agreement UPR
     shareholders will receive 0.4550 Anadarko common shares for each UPR common
     share. The merger transaction between UPR and Subcorp is subject to
     regulatory approval, as well as approval by both the UPR and Anadarko
     shareholders.

          In connection with the execution of the Merger Agreement, UPR and
     Anadarko entered into a Stock Option Agreement, dated as of April 2, 2000
     (the "UPR Stock Option Agreement"), pursuant to which UPR granted Anadarko
     an option, exercisable under certain circumstances specified in the UPR
     Stock Option Agreement, to purchase up to 50,138,515 shares of UPR Common
     Stock (approximately 19.9% of the outstanding shares of UPR Common Stock,
     without giving effect to the exercise of the option) at the purchase price
     stated in the UPR Stock Option Agreement.

          In connection with the execution of the Merger Agreement, Anadarko and
     UPR also entered into a Stock Option Agreement, dated as of April 2, 2000
     (the "Anadarko Stock Option Agreement"), pursuant to which Anadarko granted
     UPR an option, exercisable under certain circumstances specified in the
     Anadarko Stock Option Agreement, to purchase up to 25,886,726 shares of
     common stock, par value $0.10 per share, of Anadarko (approximately 19.9%
     of the outstanding Anadarko common stock, without giving effect to the
     exercise of the option) at the purchase price stated in the Anadarko Stock
     Option Agreement.

          In connection with the Merger Agreement, effective as of April 2,
     2000, UPR and Harris Trust and Savings Bank, as Rights Agent, amended the
     Amended and Restated Rights Agreement, dated as of December 1, 1998,
     between UPR and the Rights Agent (the "Rights Agreement"), providing that
     each of Anadarko, Subcorp, and their affiliates shall not be deemed an
     "Acquiring Person" as defined in the Rights Agreement with respect to, and
     that no "Stock Acquisition Date", "Distribution Date", or "Triggering
     Event" will occur as a result of the execution of the Merger Agreement, the
     execution of the UPR Stock Option Agreement, the consummation of the
     transactions contemplated by the Merger Agreement, including, without
     limitation, the merger, the acquisition of beneficial ownership or transfer
     of Common Stock pursuant to the UPR Stock Option Agreement, or the
     announcement of any of the foregoing transactions, and that the Rights
     Agreement will expire immediately prior to the Effective Time of the Merger
     (as defined in the Merger Agreement).

          A supplier of coal to Black Butte Coal Company and R-K Leasing Company
     ("Black Butte") has been assessed by the Minerals Management Service of the
     United States Department of the Interior for underpayment of royalties and
     by the State of Montana Department of Revenue for underpayment of
     production taxes related to coal previously sold to Black Butte. The
     supplier contested these claims. In 1998, the Courts ruled in favor of the
     State of Montana. The supplier appealed to the Montana State Supreme Court.
     On May 9, 2000, the Montana State Supreme Court reversed the decision by
     the Montana Thirteenth Judicial District Court, which had affirmed the
     assessment made by the State Tax Appeal Board against the Supplier, and
     dismissed the assessment. The State of Montana has ten days to request a
     rehearing by the Montana Supreme Court. Through the first quarter of 2000,
     the Company had recorded $15.4 million as its proportionate share of the
     Montana Department of Revenue assessment related to coal production taxes.
     Status involving the Minerals Management Service assessment has not
     changed.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


To the Board of Directors and Shareholders of
Union Pacific Resources Group Inc.


We have reviewed the accompanying condensed consolidated statement of financial
position of Union Pacific Resources Group Inc. (a Utah corporation) and
subsidiaries as of March 31, 2000, and the related condensed consolidated
statements of income and comprehensive income and the condensed consolidated
statements of cash flows for the three month periods ended March 31, 2000 and
1999. These financial statements are the responsibility of the Company's
management.

We conducted our review in accordance with standards established by the American
Institute of Certified Public Accountants. A review of interim financial
information consists principally of applying analytical procedures to financial
data and of making inquiries of persons responsible for financial and accounting
matters. It is substantially less in scope than an audit conducted in accordance
with generally accepted auditing standards, the objective of which is the
expression of an opinion regarding the financial statements taken as a whole.
Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should
be made to the financial statements referred to above for them to be in
conformity with accounting principles generally accepted in the United States.

We have previously audited, in accordance with auditing standards generally
accepted in the United States, the statement of financial position of Union
Pacific Resources Group Inc. as of December 31, 1999, and, in our report dated
March 3, 2000, we expressed an unqualified opinion on that statement. In our
opinion, the information set forth in the accompanying condensed consolidated
statement of financial position as of December 31, 1999, is fairly stated, in
all material respects, in relation to the balance sheet from which it has been
derived.

</TABLE>


     The Company recorded net income of $95.6 million for the first quarter of
2000, compared to $175.5 million in 1999, which included income from
discontinued operations of $133.2 million. Earnings per share were $0.38 for the
quarter compared to $0.71 per share last year. Included in 2000 earnings was a
$2.9 million after-tax extraordinary gain relating to the repurchase and
extinguishment of debt.

                        RESULTS OF CONTINUING OPERATIONS

     The Company recorded income from continuing operations of $92.7 million for
the first quarter of 2000 compared to $42.3 million in the same period of 1999.
Earnings per share of $0.37 increased $0.20 per share over last year. Higher
prices contributed $189.5 million to revenues, surrendered lease costs declined
$20.8 million and interest expense dropped $15.4 million, while the first
quarter of 1999 included a $14.5 million restructuring charge related to a
reduction in force and early retirement program. Partly offsetting these
benefits were the absence of $61.1 million of 1999 gains on property sales and a
$32.9 million 1999 after-tax gain related to a Canadian tax settlement. In
addition, lower volumes reduced revenues $28.7 million, higher prices caused a
$17.2 million increase in production taxes, and the Company recorded an $11.5
million charge in 2000 related to the revaluation of firm transportation
contacts. The Company also recorded $1.7 million of after-tax foreign currency
losses for the first quarter of 2000 compared to $15.9 million of gains last
year.

     Operating income improved by $129.2 million to $188.5 million for the
quarter. Exploration and production operating income rose $112.9 million to
$172.0 million, reflecting a $1.04 per Mcfe (65%) improvement in average prices
that contributed $189.5 million, offset by the impact of lower volumes ($28.7
million) and the inclusion of $61.1 million of gains on property sales in 1999.
The lower volumes also resulted in a $7.1 million decrease in depreciation,
depletion and amortization ("DD&A") costs and exploration expenses declined
$21.3 million primarily related to lower surrendered lease costs, while
production taxes increased $17.2 million resulting from the higher prices.

     Minerals operating income of $37.0 million for the first quarter of 2000
rose $5.2 million over last year. Soda ash royalties were up $8.7 million from
higher lease revenues, while OCI Wyoming LP ("OCIW") equity income declined $2.2
million due to lower prices and volumes.

     General and administrative ("G&A") expenses, including DD&A increased $3.4
million over 1999. The G&A expense increase over 1999 was the result of higher
legal, computer, telecommunications and rental costs. Lower costs related to
Canadian operations partly offset these amounts. In addition, the Company
recorded a $14.5 million restructuring charge in the first quarter of 1999
related to its reorganization.

</TABLE>

OPERATING REVENUES

     Exploration and production revenues for the first quarter of 2000 increased
by $160.8 million (50%) to $479.8 million, largely due to the $189.5 million
increase associated with higher product prices. Lower volumes, however, reduced
revenues by $28.7 million. Hedging positions for crude oil reduced revenues by
$44.4 million in 2000 compared to a $1.1 million reduction in 1999, while
natural gas hedges resulted in additional revenues of $3.6 million in 2000 and
$11.9 million last year.

     Other oil and gas revenues decreased $58.9 million primarily from the
inclusion of $61.1 million of gains on property sales in the first quarter of
1999.

     Exploration and production volumes of 2,008.5 MMcfed decreased 223.2 MMcfed
(10%) from 1999 results, primarily due to production declines related to reduced
capital spending levels, as well as property sales. Property sales contributed
approximately 42.9 MMcfed to the volume decline.

     U.S. Onshore realized a 155.9 MMcfed decline to 1,158.9 MMcfed, with a
small improvement in the Land Grant core area being more than offset by
decreases from all other core areas. These decreases are related to the
reduction in capital spending implemented in late 1998 that continued through
1999. Canadian volumes were down 20.7 MMcfed (4%) to 457.7 MMcfed and Other
International volumes were down 34.5 MMcfed to 255.0 MMcfed also due to capital
spending reductions, production declines and the Guatemalan asphalt refinery
being down for a portion of the quarter due to civil unrest. Volumes decreased
in U.S. Offshore by 12.1 MMcfed to 136.9 MMcfed.

     Natural gas volumes decreased 159.7 MMcfd (12%) to 1,167.4 MMcfd,
principally reflecting production declines for existing properties related to
reduced capital spending levels, as well as the sale of south Texas, east Texas,
and Wahsatch properties in 1999. U.S. Onshore volumes were down 127.2 MMcfd with
declines spread across all core areas. U.S. Offshore volumes decreased 2.1 MMcfd
as improvements at East Cameron Block 270/271 and at Main Pass Block 162, were
offset by volume declines in other U.S. Offshore blocks. Canadian volumes
dropped 6.0 MMcfd, while Other International volumes declined 0.9 MMcfd.

     Natural gas liquid volumes increased 4.9 MBbld (20%) to 29.4 MBbld for the
quarter, as improvements in the Land Grant (6.5 MBbld) were offset by declines
from property sales. Land Grant volumes benefited from ethane recovery and
higher recovery rates in 2000, and were impacted by ethane and propane rejection
last year.

     Crude oil volumes of 110.7 MBbld decreased 15.6 MBbld (12%) compared to
last year. U.S. Onshore declined 5.2 MBbld with a 2.2 MBbld decline in the
Austin Chalk trend in Louisiana from high decline rates and low capital
spending levels and a 2.6 MBbld drop in the Land Grant reflecting drilling
declines for Wamsutter non-operated properties. Other International volumes
were down 5.6 MBbld, including declines in Guatemala of 3.2 MBbld from downtime
at the asphalt refinery, and Venezuela decreases of 1.7 MBbld reflecting lower
volumes from Oritupano Leona. In addition, U.S. Offshore oil volumes declined
1.7 MBbld.

OPERATING EXPENSES

     In the first quarter of 2000, production expenses increased $17.4 million
(19%) to $107.9 million, primarily reflecting higher production taxes caused by
higher sales prices. Production costs on a per unit basis were $0.59 per Mcfe,
up from $0.45 per Mcfe last year. Total lease operating expenses rose $2.5
million to $63.5 million, with higher workover costs


                                      -13-
<PAGE>   15


($3.7 million), maintenance and repair costs ($0.6 million) and compressor
rental costs ($0.4 million), reflecting low activity in 1999 driven by cost
reduction efforts. Partially offsetting these increases were lower non-op
charges ($2.8 million) and lower personnel costs ($0.8 million) resulting from
the reduction in force in the first quarter of 1999. Lease operating expenses
on a per unit basis increased from $0.30 per Mcfe in 1999 to $0.35 per Mcfe in
2000.

     Production and property taxes increased $17.2 million from 1999 due to
higher product prices in the U.S. Onshore and Guatemala. Production overhead
costs declined $1.2 million from last year largely due to lower joint venture
billings, offset by higher legal costs and costs relating to Canadian and Other
International operations.

     Exploration expenses decreased $21.3 million from last year, primarily
reflecting a $20.8 million reduction of surrendered lease costs. Surrendered
lease costs were down $14.8 million for U.S. Onshore, $2.5 million for Guatemala
and $2.3 million for Canada. Dry hole expense was down $2.2 million and delay
rentals declined $1.2 million, while geological and geophysical expenses
increased $1.9 million. Exploration overhead was up $1.0 million, primarily
reflecting higher computer costs.

     DD&A expenses decreased by $7.1 million from last year. Lower volumes
resulted in a reduction of $16.4 million while higher per unit rates resulted in
a $9.3 million offset. Per unit rates for the first quarter of 2000 were $0.96
per Mcfe, compared to $0.90 per Mcfe in 1999.

</TABLE>

     Minerals operating income of $37.0 million for the first quarter of 2000
rose $5.2 million from $31.8 million last year. Soda ash royalties were up $8.7
million from higher lease revenues, while OCIW equity income declined $2.2
million due to lower prices and volumes. In addition, coal royalties declined
$0.5 million.

GENERAL AND ADMINISTRATIVE AND OTHER INCOME/EXPENSE

     G&A expenses, including DD&A expense, increased $3.4 million to $20.5
million. The cost increase was primarily the result of higher legal expenses
($0.7 million), computer costs ($0.6 million), telecommunication costs ($0.3
million) and rental costs ($0.3 million). Partly offsetting these increases were
lower Canadian G&A expenses. In addition, the Company recorded a $14.5 million
restructuring charge in the first quarter of 1999. G&A expenses on a per unit
basis, excluding the restructuring charge, increased from $0.08 per Mcfe last
year to $0.10 per Mcfe for the first quarter of 2000.

     Other income (expense) for the quarter was an expense of $14.8 million
compared to income of $11.4 million


                                      -14-

last year. Foreign currency remeasurement losses of $5.7 million were recorded
in 2000, while 1999 included gains of $9.0 million. Also included in 2000 was an
$11.5 million charge related to the revaluation of firm transportation contract
obligations. In addition, interest income declined $2.4 million, caused by the
absence of $7.1 million of interest income from the 1999 Canadian tax
settlement, offset by interest income on cash balances in 2000.

     Interest expense in the first quarter of 2000 of $48.9 million declined
$15.4 million from last year, resulting from the Company's debt reduction
effort.

     Income tax expense from continuing operations in the first quarter of 2000
was $32.1 million compared to a benefit of $35.9 million last year, primarily
related to the improvement in pretax income caused by higher prices and the
inclusion in 1999 of a $27.9 million benefit related to the Canadian tax
settlement. In addition, 2000 taxes included $4.0 million of foreign currency
gains related to the remeasurement of deferred tax liabilities in Guatemala and
Venezuela, compared to $6.9 million in 1999. Section 29 credits were $3.9
million in 2000, compared to $3.4 million last year.

                      RESULTS FROM DISCONTINUED OPERATIONS

     Income from discontinued operations was $133.2 million for the first
quarter of 1999, reflecting the $157.0 million after-tax gain on the sale of the
Company's gathering, processing and marketing ("GPM") business segment to Duke
Energy Field Services, Inc. ("Duke"). Discontinued operations posted a $23.8
million after-tax loss due to a $21.5 million pretax charge related to the
revaluation of firm transportation contract obligations, as well as low margins
and product prices.

                         LIQUIDITY AND CAPITAL RESOURCES

     Cash provided by operations of $314.5 million for the quarter was $92.8
million above last year. The improvement reflects higher prices, lower interest
expense, the absence of the 1999 restructuring charge and higher minerals lease
revenues. Offsetting these benefits were lower sales volumes, lower gains from
property sales, losses instead of gains on foreign currency remeasurement, as
well as higher firm transportation contract costs.

     Cash used by investing activities was $152.5 million for the first quarter
of 2000, compared to $1.28 billion cash provided by investing activities in the
first quarter of last year. Included in 1999 were $1.36 billion of proceeds on
the sale of the GPM business segment, $200.2 million of proceeds from other
property sales, and $169.5 million of cash used in discontinued operations.
Capital and exploratory expenditures increased $44.4 million to $155.2 million
for the first quarter of 2000, reflecting the lower capital spending program in
first quarter of 1999.

     Exploration and production capital spending was up $45.7 million to $155.2
million, as the Company began to spend more with the recovery of prices in 1999
and early 2000. The major categories of capital spending include development
drilling ($94.3 million) and other development capital ($42.7 million).
Exploration and development drilling by area included $45.2 million in U.S.
Onshore, $38.5 million in Canada, $13.1 million in U.S. Offshore and $4.1
million in Other International.

     During the first quarter of 2000, the Company purchased on the open market
at a discount and retired long-term



                                      -16-
<PAGE>   18

debt with a face value of $100 million prior to maturity. The retirement of
debt due to these repurchases resulted in an extraordinary gain of $2.9 million
net of $1.5 million of tax. The gain on the retirement was classified as a gain
from an extraordinary item on the Condensed Consolidated Statement of Income.
The Company does not currently anticipate additional open market purchases of
debt in the future and expects to accumulate any excess cash flow in cash
reserves or temporary investments.

     Crude oil and natural gas prices have risen sharply in the first quarter of
2000 and the outlook for the remainder of the year is favorable for both
products. The Organization of Petroleum Exporting Countries ("OPEC") and other
countries have announced crude oil production increases which caused oil prices
to decline slightly from the higher prices during the early part of 2000.
Significant compliance with production quotas by OPEC members and other
countries is crucial to sustaining higher crude oil prices. The supply/demand
picture for natural gas is favorable. The Company expects prices to remain high
in 2000; however, price fluctuations could affect expected future net income,
cash flows and capital spending. For 2000, the Company has reduced some of its
exposure to lower prices by purchasing puts and fixed price contracts and
limited some of the upside of higher prices by selling calls and fixed price
contracts. Slightly more than one-half of the Company's estimated 2000
production was hedged at the end of the first quarter 2000. See Item 3,
Quantitative and Qualitative Disclosures About Market Risk for information
regarding the Company's hedging positions at March 31, 2000.

     The Company continues to anticipate capital spending of approximately $650
million for 2000.

     In U.S. Onshore, the Company successfully completed and tested its second
well in the Etouffee area in South Louisiana and plans a third well during the
second quarter of 2000. Increased production from these wells is anticipated
during the third quarter of 2000. Drilling on the Turtle Soup prospect, which
is near the Etouffee area, commenced and is expected to be completed during the
second quarter of 2000. The Company continues to test the Frontier formation
area of the Green River Basin in the Land Grant. The Company is currently
drilling the Sage Flat #7H well in this area, with results expected toward the
end of the second quarter of 2000. In the Wamsutter area, the Company expects
to drill about 75 wells during 2000 with its partner.

     In U.S. Offshore, the Company plans to drill at least one well during the
second quarter of 2000 in its Gomez deep-water discovery area.

     In Canada, the Company drilled the #2 and #3 Klua wells in northeast
British Columbia. Pipeline installation is underway and first production from
the Klua area is expected to commence during the third quarter of 2000. The
exploratory well at the Sullivan Creek prospect in southwestern Alberta is still
planned for the second half of 2000. The Company continued its Canadian heavy
oil drilling program by drilling 55 wells during the first quarter in the Moose
Hills and Hayter areas and expects to drill 20 additional wells during the
second quarter of 2000. Also during the second quarter, the Company expects to
drill an additional 83 wells in the Hatton area. The Company expects to complete
the sale of certain Canadian properties, primarily in the Peace River and
Provost areas, for approximately $82 million during the second quarter of 2000.

     In Guatemala, the Company drilled a successful horizontal well in the Xan
area along with a step-out well. The Xan 27 well was the Company's first attempt
utilizing its expertise in horizontal drilling on the Xan area properties.

SUBSEQUENT EVENT

     On April 2, 2000, UPR, Anadarko Petroleum Corporation, a Delaware
corporation ("Anadarko"), and Dakota Merger Corp., a Utah corporation and
wholly-owned subsidiary of Anadarko ("Subcorp"), entered into


                                      -17-
<PAGE>   19
an Agreement and Plan of Merger, dated as of April 2, 2000 (the "Merger
Agreement"), pursuant to which Subcorp will merge with and into UPR (the
"Merger"), and UPR will become a wholly-owned subsidiary of Anadarko. Under the
Merger Agreement UPR shareholders will receive 0.4550 Anadarko common shares for
each UPR common share. The merger transaction between UPR and Subcorp is subject
to regulatory approval, as well as approval by both the UPR and Anadarko
shareholders.

     In connection with the execution of the Merger Agreement, UPR and Anadarko
entered into a Stock Option Agreement, dated as of April 2, 2000 (the "UPR Stock
Option Agreement"), pursuant to which UPR granted Anadarko an option,
exercisable under certain circumstances specified in the UPR Stock Option
Agreement, to purchase up to 50,138,515 shares of UPR Common Stock
(approximately 19.9% of the outstanding shares of UPR Common Stock, without
giving effect to the exercise of the option) at the purchase price stated in the
UPR Stock Option Agreement.

     In connection with the execution of the Merger Agreement, Anadarko and UPR
also entered into a Stock Option Agreement, dated as of April 2, 2000 (the
"Anadarko Stock Option Agreement"), pursuant to which Anadarko granted UPR an
option, exercisable under certain circumstances specified in the Anadarko Stock
Option Agreement, to purchase up to 25,886,726 shares of common stock, par value
$0.10 per share, of Anadarko (approximately 19.9% of the outstanding Anadarko
common stock, without giving effect to the exercise of the option) at the
purchase price stated in the Anadarko Stock Option Agreement.

     A supplier of coal to Black Butte Coal Company and R-K Leasing Company
("Black Butte") has been assessed by the Minerals Management Service of the
United States Department of the Interior for underpayment of royalties and by
the State of Montana Department of Revenue for underpayment of production taxes
related to coal previously sold to Black Butte. The supplier contested these
claims. In 1998, the Courts ruled in favor of the State of Montana. The supplier
appealed to the Montana State Supreme Court. On May 9, 2000, the Montana State
Supreme Court reversed the decision by the Montana Thirteenth Judical District
Court, which had affirmed the assessment made by the State Tax Appeal Board
against the supplier, and dismissed the assessment. The State of Montana has ten
days to request a rehearing by the Montana Supreme Court. Through the first
quarter 2000, the Company had recorded $15.4 million as its proportionate share
of the Montana Department of Revenue assessment related to coal production
taxes. Status involving the Minerals Management Service assessment has not
changed.

"estimate," "expect," "predict," "anticipate," "goal," "should", "could",
"assume," "believe" or other words that convey the uncertainty of future events
or outcomes.

     Such forward-looking information is based upon management's current plans,
expectations, estimates and assumptions and is subject to a number of risks and
uncertainties that could significantly affect current plans, anticipated
actions, the timing of such actions and the Company's financial condition, cash
flows and results of operations. As a consequence, actual results may differ
materially from expectations, estimates or assumptions expressed in or implied
by any forward-looking statements made by or on behalf of the Company. The risks
and uncertainties include generally the volatility of crude oil, natural gas and
hydrocarbon-based financial derivative prices; basis risk and counterparty
credit risk in executing hydrocarbon price risk management activities; economic,
political, judicial and regulatory developments; competition in the oil and gas
industry as well as competition from other sources of energy; the economics of
producing certain reserves; the oil and gas industry's consolidation activity;
demand for and supply of oil and gas; the ability to find or acquire and develop
reserves of natural gas and crude oil; and the actions of customers and
competitors. Additionally, unpredictable or unknown factors not discussed herein
could have material adverse effects on actual results related to matters which
are the subject of forward looking information.

     With respect to expected capital expenditures and drilling activity,
additional factors such as crude oil and natural gas prices the extent of the
Company's success in acquiring oil and gas properties and in identifying
prospects for drilling, exploration and operating risks, the success of
management's cost reduction efforts, the ability to find working interest
partners to share certain capital risks and the availability of technology may
affect the amount and timing of such capital expenditures and drilling activity.
With respect to changes in production and sales volumes and estimated reserve
quantities, factors such as the extent of the Company's success in finding,
developing and producing reserves, the timing of capital spending, uncertainties
inherent in estimating reserve quantities and the availability of technology may
affect such production and sales volumes and reserve estimates.

     With respect to liquidity, factors such as the state of domestic capital
markets, credit availability from banks or other lenders and the Company's
results of operations may affect management's plans or ability to incur
additional indebtedness. With respect to cash flow, factors such as changes in
crude oil and natural gas prices, environmental matters and other contingencies,
hedging activities, and the Company's credit rating and debt levels may affect
the Company's ability to generate expected cash flows. With respect to
contingencies, factors such as changes in environmental and other domestic and
foreign governmental regulation, and uncertainties with respect to legal matters
may affect the Company's expectations regarding the potential impact of
contingencies on the operating results, cash flows or


                                      -19-

financial condition of the Company. Certain factors, such as changes in crude
oil and natural gas prices and underlying demand and the extent of the Company's
success in exploiting its current reserves and acquiring or finding additional
reserves may have pervasive effects on many aspects of the Company's business in
addition to those outlined above.

     With respect to the pending Merger transaction with Anadarko, factors such
as the risk that the Merger is not approved by the shareholders of the Company
or Anadarko or that it is delayed for regulatory or other reasons, or necessary
approvals are not obtained, or that, if it is approved and consummated, the
expected benefits of the Merger are not realized, including that costs or
difficulties related to the integration of the business of the Company and
Anadarko are greater than expected, including dependence on key personnel to
manage the integration of the two companies.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

NON-TRADING ACTIVITIES

     Commodity Price Risk. The Company uses derivative financial instruments for
non-trading purposes in the normal course of business to manage and reduce risks
associated with price volatility, contractual commitments and other market
variables. Utilization of the Company's hedging program may result in the
realization on the crude oil and natural gas prices varying from market prices
that the Company receives from the sales of crude oil and natural gas. As a
result of the hedging programs, revenues in the first quarter of 2000 were $40.8
million lower than if the hedging program had not been in effect. At March 31,
2000, the Company had margin deposits of $23.3 million.

     The following table summarizes the Company's open positions at March 31,
2000, related to equity natural gas and crude oil production:

<PAGE>   2

                            DAYWORK DRILLING CONTRACT


     1.1 DATE AND PARTIES: This Contract is made as of this 1st day of January,
2000, between Union Pacific Resources Company, a Delaware corporation
(hereinafter referred to as "Operator"), and Noble Drilling (U.S.) Inc., a
Oklahoma corporation (hereinafter referred to as "Contractor"), each of which is
hereinafter referred to individually as "Party" and collectively as "Parties",
regarding operations to be conducted for Operator by Contractor utilizing the

                                       2

<PAGE>   3

     2.2 RIG DELIVERY AND ACCEPTANCE: Operator and Contractor agree that the rig
shall be delivered (as defined in Section 2.1) by Contractor (hereinafter
referred to as the "Delivery Date"), subject to Rig Acceptance as follows. Rig
Acceptance shall be defined as that point in time when Amerada Hess Corporation
(the "other Rig Share Party") accepted the Rig on January 1, 2000. Operator
shall have the right (but not the obligation) to make its own independent
inspection of the rig at any time prior to delivery of the rig to Operator
(provided that Operator shall not unreasonably interfere with the rig
operations) and also shall have the right to fully review the commissioning
reports as prepared by Contractor's surveyor/inspector MODU SPEC. Subject to
Operator being allowed access to the rig and to the MODU SPEC inspection reports
as described above, Operator shall stipulate in writing any deficiencies in the
rig (as compared to other specifications in the Exhibits attached hereto).

     2.3 SPECIFIED CONTRACT TERM: Beginning upon the Contract effective date
(Item A-1, Exhibit A), Operator may utilize the rig during alternating Drilling
Slots (as particularly described below), such that, after completion of the
first Drilling Slot (which is to be used by the other Rig Share Party) Operator
will utilize the rig for a total of 456.25 days, which shall be deemed the
Specified Contract Term.

     2.3.1 Subject to the other provisions of this Contract, the rig shall be
           utilized by Operator as follows:

        a) Year 2000- Ninety (90) days by the end of the first six months and a
           cumulative of one hundred and eighty (180) days by the end of the
           year.

        b) Year 2001- A cumulative total of two hundred and seventy (270) days
           by year end.



                                       3
<PAGE>   4

        c) Year 2002- A cumulative total of two hundred and seventy (270) days
           by year end.

        d) Year 2003- A cumulative total of three hundred and sixty five (365)
           days by year end.

        e) Year 2004- A cumulative total of four hundred fifty-six and one
           quarter (456.25) days by year end.

     2.3.2 This Section 2.3.2 shall determine the rotational sequence of
     Operator's Drilling Slots.

       (a) Subject to the other provisions of this Section 2.3.2, during the
           Specified Contract Term, Operator shall have the right, but not the
           obligation, to utilize the drilling rig on an alternating Drilling
           Slot basis (i.e. every other Drilling Slot).

       (b) During the first six months of the year 2000, and commencing with the
           second Drilling Slot, Operator shall utilize the rig on an
           alternating Drilling Slot basis until it has utilized the rig for at
           least ninety days. During the second six months of the year 2000,
           commencing with the next available Drilling Slot after June 30 of
           that year, Operator shall utilize the rig on an alternate Drilling
           Slot basis until it has utilized the rig for the cumulative period
           set forth in Section 2.3.1(a).

       (c) Commencing with the year 2001, in any calendar year in which Operator
           has an unsatisfied cumulative obligation, Operator may utilize the
           rig for the first Drilling Slot which becomes


                                       4
<PAGE>   5

           available and, if not utilized sooner, Operator shall utilize the rig
           for the first Drilling Slot which becomes available after March 1
           and, thereafter, will utilize the rig on an alternate Drilling Slot
           basis for such year until Operator has met its cumulative obligation
           for such year. Example: At the beginning of 2001, Operator has used
           the rig for a cumulative 180 days. Operator is not obligated, but may
           utilize the rig for the next available Drilling Slot in 2001, but
           shall be obligated to utilize the rig for the first Drilling Slot
           which becomes available after March 1, 2001.

       (d) If in any calendar year Operator`s cumulative remaining obligation
           for that year is less than 30 days, Operator shall have no obligation
           to utilize the rig for the remainder of that year and such remaining
           obligation will be carried forward and added to the succeeding
           calendar year. Example: During the year 2000, Operator has utilized
           the rig for a total of 170 days. Since the 10 days of remaining
           cumulative obligation is less than 30 days, the 10 days shall carry
           over to 2001 and Operator's obligation for that year will be 100 days
           and its cumulative obligation will remain 270 days.

       (e) If in any calendar year Operator is unable to meet its cumulative
           obligation for that year because the rig is being used by another
           party (including Contractor), then Operator's remaining obligation
           for that year will be carried over to the next calendar year and
           Operator's cumulative obligation will remain unchanged. Example:
           During year 2003, Operator has utilized the rig for a cumulative
           total of 320 days, but is unable to take a Drilling Slot to meet its
           cumulative obligation because the rig is being utilized by another
           party. The remaining 45 days obligation shall carry


                                       5
<PAGE>   6


           over to 2004 and Operator may utilize the rig in the first available
           Drilling Slot in 2004, but shall be obligated to utilize the rig for
           the first Drilling Slot which becomes available after March 1, 2004

       (f) If as a result of the application of this Section 2.3.2, and subject
           to the other provisions of this Contract, Operator has not utilized
           the rig for a cumulative total of 456.25 days by the end of year
           2004, any remaining obligation shall carry over to the year 2005, and
           Operator shall utilize the rig in the next available Drilling Slot
           for that year and, thereafter, on an alternating Drilling Slot basis
           until the end of the Specified Contract Term. Notwithstanding the
           preceding sentence, Operator shall have no obligation to utilize the
           rig in 2005 to the extent Operator has not been able to meet its
           remaining cumulative obligation in 2004 because the rig was utilized
           in full in 2004 by another operator (including Contractor when it is
           utilizing the rig).

    2.3.3 Contractor and Operator may, at any time after the Contract Effective
          Date, agree to modify the above-described Drilling Slot rotational
          sequence as required to fulfill Operator's term obligation above.

    2.3.4 Operator may decide to assign one or more of its Drilling Slots
          hereunder to a third party and that, subject to Contractor's approval
          pursuant to Section 30.1, all such slots assigned by Operator shall be
          utilized in calculating the duration and expiration of the Specified
          Contract Term.

      2.4  DRILLING SLOTS:

       a)  The term "Drilling Slot", when used in this Drilling Contract, shall
           be that period of time, not to exceed ninety (90) days (except as
           provided in Section 2.4(c) below), that is required to mobilize the
           rig to a drill site, drill one or more wells (including partial
           wells), and demobilize the rig to the point where all anchors have
           been bolstered and the rig has moved at least one hundred (100) yards
           from the utilizing Party's well location. Operator's respective
           Drilling Slots shall commence upon transfer of the rig to Operator
           (as described in Section 19.10(ii)) and shall cease upon transfer of
           the rig by Operator to the other Sharing Party, another operator or
           to Contractor for stacking (as referenced in Section 19.10(i).

       b)  The Drilling Slot shall be construed to include, without limitation,
           all pre-drilling of surface holes, drilling, mechanical side
           tracking, geologic side tracks, batch setting casing strings,
           installation of sub-sea equipment, deepening, testing, completing,
           plugging, abandonment and associated operations, as appropriate, at a
           single drill site (i.e. a well slot or template). A Drilling Slot
           shall not be less than thirty (30) days nor more than ninety (90)
           days, except as provided below. The term "Drilling Slot shall also
           apply to (i) the use of the rig by the other Sharing Party or another
           operator (including Contractor when Contractor is using the rig)
           which shall be for the minimum and maximum periods set forth in this
           Section 2.4; and (ii) Contractor's stacking of the rig; provided that
           such stacking shall be for a minimum of ninety (90) days after
           completion of a Drilling



                                       7
<PAGE>   8

           Slot (unless Contractor and Operator agree otherwise or after
           stacking another operator takes the rig for a Drilling Slot), as
           described in Section 2.4(a) above, before transfer of the rig back to
           Operator.

       c)  If operations are continuing at the same drilling location (well slot
           or template), then Operator's (or another rig sharing party's)
           Drilling Slot can be extended by ninety (90) days up to a cumulative
           total of 180 days without the Contractor's consent; provided that the
           Operator shall notify the Contractor, at least thirty (30) days prior
           to the end of the basic ninety (90) day Drilling Slot, of Operator's
           intent to retain the rig beyond the end of said period. If Contractor
           has a commitment to another sharing party for the next Drilling Slot,
           Operator shall make every effort to suspend or abandon the well in
           progress at or as near as possible to the expiration of the maximum
           180-day period, unless the Contractor agrees in writing to further
           extend the Drilling Slot.

       d)  If the time required to drill the initial well in any Drilling Slot
           is less than thirty (30) days, then the Operator (or other rig
           sharing party, as the case may be) shall have the right and
           obligation to further utilize the rig to fulfill the minimum term of
           its Drilling Slot, including the right to move the rig to a different
           location.

       e)  During its use of the rig for a Drilling Slot, Operator shall provide
           Contractor at least 30 days advance written notice of the date it
           expects such Drilling Slot to cease. During times when Operator is
           not utilizing the rig, Contractor shall provide Operator at least 30
           days advance written notice of the next available Drilling Slot in


                                       8
<PAGE>   9

           order that Operator may prepare for and/or elect such Drilling Slot
           in accordance with the provisions of this Contract. Operator shall
           advise Contractor within 15 days after it receives Contractor's
           notice whether it will utilize the rig in the next Drilling Slot.

     2.5 OPERATOR'S SEPARATE SLOT USAGE: Operator's obligations to Contractor
under this Contract pursuant to its Drilling Slots shall be Operator's sole and
separate responsibility, as between Operator and Contractor; and likewise,
Operator shall have no obligation to Contractor with regard to any Drilling
Slots utilized (or failed to be utilized) by another sharing party, or utilized
by Contractor, or for stacking. It is agreed that this Drilling Contract shall
not apply to any Drilling Slots utilized by any other sharing parties and that
Operator shall have no collective, joint or other responsibility for any
liabilities, obligations, damages or other costs of whatever type incurred by
any person or party arising out of any Drilling Slots other than Operator's own
Drilling Slots. Operator will cooperate with Contractor and any rig sharing
party, in order to facilitate the alternating Drilling Slot procedure described
in Sections 2.3 and 2.4.

     3.1 CONTRACTOR'S PERSONNEL: Contractor shall furnish, at Contractor's cost,
the personnel in the numbers, classifications and work schedules set forth in
Exhibit B. All such personnel shall be employed directly by Contractor and are
referred to in this Contract as "Contractor's Personnel". At the request of
Operator, Contractor shall furnish such additional personnel as Operator may
designate, such additional personnel to be considered as part of Contractor's
Personnel, and Operator shall reimburse Contractor for the direct costs and
expenses (such as hiring benefits, social security, wages and other



                                       9
<PAGE>   10


direct payroll burdens) of furnishing all such additional Contractor's
Personnel, as set forth in Exhibit B. If, with Operator's consent, the number of
Contractor's Personnel is reduced, Operator shall be credited with the savings
thereby effected. Contractor shall have a full drilling crew of personnel, as
set forth in Exhibit B, working at all times when receiving pay at such of the
dayrates set forth in Exhibit A calling for a full drilling crew. If
circumstances beyond the control of Contractor temporarily prevent Contractor
from having a full drilling crew working, Contractor shall receive the full
applicable rate only if Operator determines, in its sole discretion, that there
is no delay in the progress of the work. Otherwise, the applicable rate shall be
reduced by the daily rate of pay and benefits for each person that a crew is
short.

     4.1 CONTRACTOR'S EQUIPMENT: Contractor shall furnish, at Contractor's cost,
the drilling unit, equipment and facilities referred to in the Contract as
"Contractor's Equipment" and as set forth in Exhibit C. In addition, except for
Operator's Equipment as described in Section 7.1 and Exhibit D, all other
materials, equipment, tools, appliances, machinery, services and supplies for
the proper drilling, completing, abandoning, working over or deepening, and for
protecting the rig and wells involved shall be furnished and installed by and at
the expense of Contractor. All such drilling unit equipment and other items to
be furnished by Contractor are hereinafter called "Contractor's Equipment".

     4.2 RIG SPECIFICATIONS: If, as a result of the construction process or
field operations after delivery of the first EVA drilling units 1, 2, 3, and 4,
it is determined that certain design changes, additions or upgrades are
necessary for the "Noble Max Smith" to achieve the efficient operational
capabilities as provided for in this Contract, the following shall apply:



                                       10
<PAGE>   11

          A.   Any changes, additions or upgrades that Contractor provided for

               stack location and has been transferred to Operator, until all
               anchors have been set and the unit is ready to ballast at
               Operator's location.

     20.1 PAYMENT OF INVOICES; AUDIT: If requested by Operator, Contractor will
furnish Operator with satisfactory evidence of the validity and prior payment by

of all labor and material claims incurred by Contractor. Operator shall have the
right to withhold payment of any invoice or part of any invoice wherein there is
a bona fide question or dispute as to propriety and/or amount. Subject to this
right, Operator shall pay invoices within thirty (30) days of receipt from
Contractor. Any undisputed invoices not paid within fifteen (15) days of such
period shall bear interest at a rate of one-half of one percent (0.5%) above the
rate of interest announced publicly by Citibank, N.A., from time to time as its
prime rate.

     Payment of any invoice shall not prejudice the right of Operator to
question the propriety of any charges therein, and Operator, prior to or
subsequent to making any payments to Contractor, shall have the right to audit
the books, records and invoices of Contractor which are involved in the
performance of this Contract, to verify any and all charges so made by
Contractor; provided, however, that Operator, at any time during this Contract
and continuing until two (2) years after the termination of this Contract, shall
deliver to Contractor written notice of objections to any item or items therein,
the propriety of which it questions, specifying the reasons for such objections.
Should Operator within such two (2) year period so notify Contractor, adjustment
shall be made between the parties accordingly as the propriety or impropriety of
such items shall be determined. Failure to notify Contractor within said two (2)
year period shall be deemed final approval of said invoice(s). Contractor shall
retain all records pertinent to its invoices for at least two (2) years
following the calendar year during which any such invoice(s) are received by
Operator. Notwithstanding the foregoing, Operator shall have no right to examine
or audit Contractor's trade secrets, proprietary information, confidential data,
costs, margins, and any other methods used to determine Contractor's dayrates
hereunder.

liens, claims, assessments, fines and levies created or committed by Contractor
or by its subcontractors, suppliers and other parties claiming by, through or
under Contractor. Operator may post on Contractor's Equipment such notices as it
may desire to protect itself against such liens, claims, assessments, fines and
levies.

     22.1 TAXES OR LEVIES: Contractor shall be responsible for all taxes, fees
and other assessments levied by any federal, state, county, parish or local
governmental entity having jurisdiction hereof, to the extent attributable to or

Except as provided above, Operator shall be responsible for any federal, state,
county, parish or local taxes that may be applicable to Operator's operations
hereunder.

sole expense, secure and maintain, with an insurance company or companies
authorized to do business in the Area of Operations (as set forth in Section 8.1
above and in Item A-11 of Exhibit A) and reasonably satisfactory to Operator, or
through a self insurance program reasonably satisfactory to Operator, insurance
policies or equivalent coverages of the kind and in the amounts as set forth in
Exhibit E.

     Contractor's insurance shall be primary only to the extent of Contractor's
respective responsibilities, obligations and liabilities assumed hereunder, and
Operator's insurance policies shall not be called upon for contribution as to
such matters nor shall Operator have any obligation for "sue and labor". In each
policy under which Operator is an assured, Contractor agrees to waive and agrees
to have its insurers waive any rights of subrogation they may have against
Operator, and all other indemnitees hereunder (as defined in Section 23.13), to
the extent of Contractor's respective responsibilities, obligations and
liabilities hereunder. It is further agreed that each such policy, other than
Worker's Compensation policies, shall name Operator and all other indemnitees
hereunder as additional insureds to the extent of Contractor's responsibilities,
obligations and liabilities hereunder. Contractor shall be solely responsible
for any deductibles required under each such policy.

<PAGE>   27

     Prior to commencing work hereunder, Contractor shall furnish an Accord
Certificate of Insurance Form or other documentation evidencing the required
coverages, to Operator's reasonable satisfaction. The submission of said Form or
other documentation shall not constitute a waiver of the insurance requirements
set forth in Exhibit E. Each insurance policy shall contain a provision
obligating the insurer to give Operator written notice not less than thirty (30)
days prior to any change in the policy and ten (10) days prior to cancellation
thereof.

     It is expressly agreed that the amounts of insurance set forth in Exhibit E
to this Contract are minimums only and in no way limit Contractor's obligations
and liabilities with respect to any defense, hold harmless and indemnity
obligations assumed by Contractor under the terms of this Contract. Operator and
Contractor further agree that the insurance coverages provided herein shall not
be a defense to the indemnity obligations of Contractor as the indemnitor.

     23.2 SUBCONTRACTOR'S INSURANCE: Contractor shall require its subcontractors
to secure and maintain all of the insurance coverages set forth in Exhibit E,
and any deficiencies in the coverage or policy limits of such subcontractors'
insurance coverages shall be the responsibility of Contractor.

     23.3 CONTRACTOR'S EQUIPMENT:

             23.3.1 Surface Equipment. Contractor shall assume liability at
                    all times for, and shall defend, release, indemnify and hold

                    machinery and appliances and also in-hole equipment when not
                    in the hole, excluding only subsea equipment when below the
                    surface of the water as particularly provided for in Section
                    23.3.2 and equipment in the hole as described in Section
                    23.3.2) and for the removal of wreck or debris in connection
                    therewith. Operator shall be under no liability whatsoever
                    to reimburse Contractor for such damage, destruction or

             23.3.2 Contractor's In-Hole and Subsea Equipment: Operator shall
                    assume all risk of loss of or damage to Contractor's in-hole
                    equipment, on a depreciated value basis, as particularly
                    provided in Section 23.3.3 below, when such equipment is in
                    the hole or below the surface of the water, regardless of
                    when or how such destruction or damage occurs, except that
                    Contractor shall assume all risk of the foregoing loss or
                    damage if caused by Contractor's gross negligence or willful
                    misconduct. In the event Contractor's subsea or mooring
                    equipment (including, but not limited to, blowout preventer,
                    connectors, buoys, pendant wires, anchors, and anchor chain,
                    but including no part of the drilling rig proper or its
                    appurtenances below the water line) is lost or damaged below
                    the surface of the water and such loss or damage is not
                    solely the result of Contractor or Contractor's employees'
                    or subcontractors' negligence or other fault, Operator
                    agrees to pay Contractor a sum



                                       28

<PAGE>   29

                    equal to one-half (1/2) of Contractor's actual losses or
                    damage, but not to exceed One Hundred Fifty Thousand Dollars
                    ($150,000) for each separate incident or occurrence and
                    Three Hundred Thousand Dollars ($300,000) in the aggregate

                    agrees, at Operator's option, to repair, replace with the
                    same type of equipment or reimburse Contractor, to the
                    extent not covered by Contractor's insurance, at the current
                    repair cost or ninety percent (90%) of the current new
                    replacement cost for drill pipe, tool joints and drill
                    collars, whichever is less, when any such equipment is
                    damaged or lost in the hole, unless such loss or damage is
                    caused by Contractor's gross negligence or willful
                    misconduct.

             23.3.4 Property of Contractor's Subcontractors. Property of
                    subcontractors of Contractor shall be considered

                    wreck or debris. Contractor shall be under no liability
                    whatsoever to reimburse Operator for such damage,

     23.5 EMPLOYEES: Contractor shall defend, release, indemnify and hold
Operator harmless from and against all claims, demands and causes of action of
every kind and character, without limit and without regard to the cause(s)
thereof or the negligence of any party or parties (including Operator) arising

thereof or the negligence of any party or parties (including Contractor) arising
in connection herewith, for injury to or illness or death of Operator's
employees and for all damages to, loss or destruction of property of Operator's
employees.

     23.6 THIRD PARTIES: Contractor shall defend, release, indemnify and hold

attributable



                                       30
<PAGE>   31

(i.e. in proportion, on a comparative fault basis, as applicable) to the
negligence (whether sole, gross, joint or concurrent, active or passive), breach
of warranty, premises liability, unseaworthiness or other defective condition
(whether pre-existing or otherwise) of any vessel, vehicle, facility, equipment,
tool, material or other items whatsoever, other fault or strict liability of the
indemnifying party or any of its employees.

     23.7 LOSS OF HOLE: In the event the hole is lost or damaged, Operator shall
be responsible for any such loss of or damage to the hole; provided, however,
that if such loss or damage is caused by Contractor's sole or gross negligence
or willful misconduct, Contractor shall, at Operator's election, drill a new
hole on the same location or redrill such section of the hole as Operator may
require, and Contractor shall be paid at eighty percent (80%) of the applicable
dayrate, until the new hole has reached the depth at which the old hole was
abandoned or, as the case may be, the section has been redrilled to the
satisfaction of Operator.

     23.8 BLOWOUT OR CRATER: In the event a well being drilled shall blowout or
crater from any cause, Operator shall bear the entire cost of killing the well
or otherwise bringing it under control, and shall hold harmless, release,
indemnify and defend Contractor for any such incident, subject to the provisions
of Section 23.13. This assumption applies only to the actual blowout or crater
and the cost of bringing the well under control and has no application to the
loss of property, injuries, damage or pollution caused by such blowout, which
are covered elsewhere in this Contract. Operator shall have the right to use all
Contractor's Equipment and Contractor's Personnel, subject to Contractor's
underwriter's approval (which shall not be unreasonably withheld), during such
times as Operator, or both Operator and Contractor, are engaged in bringing a
well under control. During such time

                    materials are in Contractor's custody or control, to the
                    extent - that any such spill, leak or dumping is
                    attributable (i.e. in proportion, on a comparative fault
                    basis, as applicable) to Contractor's negligence or failure
                    to comply with Operator's direction; provided that
                    Contractor's maximum liability to Operator under this

                    submerged lands, ruptured or damaged by Contractor's rig,
                    barge, anchors, equipment, or other operations, except that
                    Contractor shall not be responsible for pollution when the
                    pipeline rupture or damage is caused by the positioning or
                    operation of Contractor's Equipment at the specific location
                    designated by Operator, or by the actual positioning of such
                    equipment (whether or not correct) by Operator; provided
                    that Contractor's maximum liability to Operator under this
                    Section 23.10.3 shall not exceed One Million Dollars
                    ($1,000,000) on a per occurrence basis, excepting only as

                    conduct of operations hereunder, subject to the provisions
                    of Sections 23.8 and 23.10.3;

            23.10.5 resulting, except as provided in 23.10.2, from possession,
                    use or disposition of oil emulsion, oil base or chemically
                    treated drilling fluids, contaminated cuttings, and lost
                    circulation and fish recovery materials and fluids,
                    including such possession, use or disposition by Operator's
                    other contractors; or

            23.10.6 resulting from, as referenced in 23.10.3, the positioning

containment, clean-up, removal, disposal and remediation of any pollution or
contamination which is the responsibility of Contractor under the foregoing
provisions; and Contractor shall reimburse Operator for the actual costs
thereof. In addition, Operator reserves the right to perform subsea inspections
for pollution and contamination which is the responsibility of Contractor during

moving the drilling unit to the drilling location, Contractor will determine,
based upon the said surveys, that said location is free from impediments and/or
hazards, including but not limited to, pipelines, cables, boulders, mud-filled
depressions, and other obstructions. In the event the drilling location is not
free from impediments and/or hazards, Operator shall remove such impediments
and/or hazards, as requested by Contractor prior to moving the drilling unit to
the drilling location, or Operator shall select another drilling location
satisfactory to Contractor. Contractor shall not move the drilling unit to the
drilling location until it notifies Operator that such location is acceptable.
Upon commencement of moving the drilling unit to the drilling location,
Contractor shall be deemed to have assumed all risks associated with the
drilling location and to have released Operator from any and all liabilities and
costs with respect thereto, except to the extent attributable to an error(s) in
any site condition survey or other information furnished by Operator.

     23.13 GENERAL DEFENSE, RELEASE, HOLD HARMLESS & INDEMNITY: It is the
specific and expressed intent and agreement of Operator and Contractor that all



                                       36
<PAGE>   37

defense, release, hold harmless and indemnity obligations and/or liabilities
assumed by Operator and Contractor respectively under the terms of this
Contract, unless expressly limited or otherwise provided for in this Contract,
shall be without limit and without regard to the cause or causes of any incident
giving rise to any such obligations and/or liabilities, including, without
limitation, the negligence (whether active or passive, sole, joint, concurrent
or gross), other fault (excepting only as otherwise provided hereinbelow), or
strict liability of any Party, the unseaworthiness of any vessels or crafts
(including the drilling unit), ruin or defective premises, equipment,
facilities, appurtenances or location of any Party under any code, law,
regulation, order or other governmental directive, whether or not such ruin or
defect pre-exists this Contract and/or is latent, patent or otherwise.
Notwithstanding any of the foregoing, none of the defense, release, hold
harmless and indemnity obligations and/or liabilities assumed by Operator under
this Contract shall apply to protect Contractor from any claims, liabilities,
losses, causes of action, damages or other costs to the extent attributable to
Contractor's recklessness or intentional misconduct, except that in no event
shall Contractor be liable for damage to Operator's geological formations,
strata or oil and gas reservoirs and also except that Contractor's liability to
Operator for pollution or contamination shall not exceed a maximum of One
Million Dollars ($1,000,000) per occurrence in the event of Contractor's
recklessness and Two and One-Half Million Dollars ($2,500,000) per occurrence
for Contractor's intentional misconduct.

     As used in Sections 23.1 through 23.16, references to "Operator", when such
word is used in the context of an indemnitee or other protected party, shall
include Operator, its co-venturers, co-lessees, their affiliates (as such term
is defined in Regulation C of the Securities Act of 1933) and subsidiaries and
their respective owners, directors,



                                       37
<PAGE>   38

officers, agents, employees and insurers; and references to "Contractor", when
such word is used in the context of an indemnitee or other protected party,
shall include Contractor, Contractor's parent, affiliates and subsidiaries, and
their respective owners, directors, officers, agents, employees and insurers,
and the drilling unit, its owners and insurers.

     In the event all or any portion of any indemnity, insurance or other
provision(s) of this Contract is held or otherwise determined to be illegal,
invalid or unenforceable pursuant to any law, rule, regulation, order or other
directive of any judicial or governmental body, agency or other authority having
jurisdiction thereof (including, without limitation, if it is judicially
determined by any lawfully constituted tribunal with jurisdiction over the
Parties that the monetary limits of insurance carried by Operator and
Contractor, which shall also be deemed to include any self insurance, or the
monetary limits of the hold harmless, defense, release and indemnity agreements
voluntarily and mutually assumed by Operator and Contractor in this Contract
exceed the maximum limits permitted under applicable law), the unenforceable or
invalid portion(s) of such provision shall be deemed to be automatically deleted
and/or amended, as of the effective date of such holding, to the extent required
to fully comply with such holding, including, without limitation, the automatic
amendment of any insurance (including self insurance), hold harmless, defense,
release and indemnity agreements to conform to the maximum monetary limits
permitted under such law or holding). All provisions of this Contract which are
unaffected by any such law or other holding shall continue in full force and
effect, together with the amended provisions as described above.

     23.14 CLAIMS: All claims against Contractor for labor (including, but not
limited to, social benefits, termination pay or similar benefits), services and
other items required or



                                       38
<PAGE>   39

used hereunder by Contractor shall be paid promptly when due, and Contractor
shall indemnify, release, defend and hold harmless Operator from and against all
liabilities, demands and expenses involving all such claims.

     23.15 CONSEQUENTIAL DAMAGES: Notwithstanding any other provision contained
herein, neither Party shall be liable to the other for special, indirect or
consequential damages resulting from or arising out of this Contract, its
performance or breach, which shall be deemed to include, without limitation,
loss of profit, delay in or loss of production or business interruptions,
however same may be caused.

     23.16 ENFORCEMENT: In the event that either Party hereto is required to
seek judicial enforcement of the contractual indemnities and other obligations
and liabilities of the other Party, the Party entitled to such protection
hereunder shall recover all reasonable attorneys' fees, court costs and other
expenses incurred in connection with pursuing that claim, through litigation or
otherwise.

     24.1 OPERATOR'S AUTHORIZED REPRESENTATIVES: Operator shall furnish
Contractor in writing a list of Operator's representatives and employees
authorized to receive all information pertaining to logs, records, reports,
cores, core data and any other information on wells drilled or any work
performed under this Contract. Operator, its representatives and authorized
employees shall have the right at all times to receive all information, to
inspect all work performed hereunder, to witness and check all measurements and
tests and to have free access to the drilling unit.

     25.1 RECORDS AND REPORTS: Contractor shall furnish and shall prepare a
complete and accurate record on the IADC-API Daily Drilling Report form of all
work performed under this Contract on all wells hereunder and shall furnish
Operator with three



                                       39
<PAGE>   40

(3) legible carbon copies of said report properly signed by Contractor's and
Operator's representatives. Contractor shall keep and provide Operator, in the
manner specified by Operator, with delivery tickets and any other warehouse
records covering any materials and supplies furnished to Operator for which
Contractor shall be reimbursed by Operator. The quantity, description and
condition of material and supplies shall be properly certified by Contractor.

     25.2 CONFIDENTIAL NATURE OF RECORDS: All logs, cores, core data, cuttings,
reports and records pertaining to the performance under the Contract shall be
open at all times to the inspection of Operator, its representatives and
authorized employees, and shall not be exhibited nor the contents divulged by
Contractor or Contractor's Personnel to any other person, without Operator's
prior written consent.

     26.1 DISCIPLINE AND SAFETY: Contractor shall, at all times, maintain strict
discipline and good order among its employees, and its subcontractor's
employees, and shall take full responsibility for the safety of its work,
including the supervision and performance of all its employees and
subcontractors. Contractor shall maintain and enforce at all times a safety
program covering its employees, subcontractors and other workers associated with
the drilling unit and shall take all other necessary precautions, in order to
perform its work hereunder in a safe manner and to avoid and eliminate any
hazards present at the work site or otherwise involving Contractor's work
(including, without limitation, any work involving the use of any toxic,
hazardous or extremely hazardous chemicals).

     Without limiting its foregoing obligations, Contractor shall use its best
efforts to ensure that its employees, subcontractors and other workers become
familiar with and



                                       40
<PAGE>   41

abide by Operator's "Contractor Safety Requirements" attached hereto and made a
part hereof as Exhibit "H". Operator's "Contractor Safety Requirements" shall
not be deemed to be an exclusive description of Contractor's safety obligations
hereunder and shall be in addition to Contractor's own program.

     No smoking or open flame or matches or lighters shall be permitted on the
drilling unit except in areas designated by Contractor in consultation with
Operator as areas wherein smoking or open flame are permitted. Contractor shall
conduct safety drills aboard the drilling unit for all personnel and shall
report same on the IADC-API Daily Drilling Report.

     In order to confirm Contractor's and its subcontractor's compliance with
all safety obligations hereunder, Operator shall have the right to audit and
review Contractor's (including all its subcontractors') safety procedures,
manuals, training and inspection records and other safety files whatsoever,
pursuant to the same procedures as for the auditing of Contractor's accounting
and other records, as described in Section 20.1

     Any violation of the foregoing safety obligations shall be considered a
material breach of this Contract; provided that Contractor shall have fifteen
(15) days after receipt of written notice to cure said breach or, if same is not
capable of cure within fifteen (15) days, to commence to cure same within said
period and diligently prosecute all corrective actions thereafter until
successfully completed.

     27.1 RELATIONSHIP OF PARTIES: Contractor shall be an independent Contractor
with regard to all services performed and other operations conducted hereunder;
and neither Contractor, its employees, Contractor's subcontractors or their
employees are agents or employees of Operator. The entire performance, including
but not limited to



                                       41
<PAGE>   42

operation, management and control of the drilling unit and other items of
Contractor's Equipment, shall be under the exclusive control and command of
Contractor. It shall be the sole and exclusive duty of Contractor to determine
by Contractor's own inspection that all supplies and items of equipment are
loaded and stored aboard said drilling unit in a proper manner, that said
drilling unit is in all respects able to undertake any contemplated operation
under the then existing conditions, in accordance with Section 6.1, and that all
operations are performed in a prudent and workmanlike manner, in accordance with
the prevailing standards for drilling contractors having experience and
expertise similar to Contractor. Operator's primary interest is in the results
to be obtained by Contractor's performance under this Contract as an independent
Contractor.

     28.1 FORCE MAJEURE: Except as otherwise provided in this Section, each
Party to this Contract shall be excused from performing under the terms of this
Contract, if and for so long as such performance is hindered or prevented by
occurrences, or the resulting effects therefrom, such as but not limited to
riots, labor disputes, strikes, lock-outs, wars (declared or undeclared),
insurrections, rebellions, terrorist acts, civil disturbances, dispositions or
orders of governmental authority, whether such authority be actual or assumed,
acts of God (other than adverse sea, weather conditions or loop currents),
inability to obtain equipment, supplies or fuel, or by any other act or cause
which is beyond the reasonable control of such Party, any such event and the
effect or results of such, being herein sometimes called "Force Majeure." If
performance is prevented by failure to comply with any governmental law, rule,
regulation,



                                       42
<PAGE>   43

disposition or order as aforesaid and the affected Party is operating in
accordance with good oilfield practice in the Area of Operations and is making
reasonable efforts to comply with such law, rule, regulation, disposition or
order, the matter shall be deemed beyond the control of the affected Party. In
the event that either Party hereto is rendered unable, wholly or in part, by any
such occurrence, or the resulting effects therefrom, to carry out its
obligations under this Contract, it is agreed that such Party shall give notice
and details of Force Majeure and its resulting effects in writing to the other
Party as promptly as possible after its occurrence. In such cases, the
obligations of the Party giving the notice shall be suspended during the
continuance of any inability so caused, except that Operator shall be obligated
to pay to Contractor the Equipment Repair Rate, the Stand-By Rate or the
Stand-By Without Crew Rate provided for in this Contract as may be applicable
and subject to any limitations associated with the appropriate rate; provided
that Operator shall not be liable to compensate Contractor for a total of
greater than fifteen (15) days hereunder, per force majeure event, occurrence,
circumstance or other condition; and the zero dayrate shall apply thereafter
until Contractor re-commences operations hereunder. At the end of one hundred
eighty (180) days from the date of such notice, either Party shall have the
option to cancel this Contract upon written notice to the other, in which
instance no further payments shall be due from Operator to Contractor, other
than as specified in Item A-21, Exhibit A. Operator shall have the right and
option, to be exercised in writing at least ninety (90) days prior to the
expiration of the Specified Contract Term, to extend said Term by the identical
number of days during which Contractor's operations for Operator were
discontinued due to any Force Majeure condition, occurrence or circumstance
hereunder. Said option shall be separately exercisable from Operator's option to
extend pursuant to Section 31.1 below.

     29.1 REPRESENTATIVES FOR NOTICES: Operator and Contractor shall each
designate a representative to receive notices as set forth in Items A-4 and A-7,
Exhibit A.



                                       43
<PAGE>   44

Such representatives may be changed by written notice to the other Party
designating a different representative.

     30.1 ASSIGNMENT: Operator, at its option, may assign this Contract, for all
or part of the term remaining, to any other Party, but only with the prior
written approval of Contractor, which shall not be unreasonably withheld.
Contractor hereby consents to any assignment of this Contract by Operator to the
other Rig Share Party. Contractor, at its option, may assign this Contract, for
all or part of the term remaining, to any other Party, but only with the prior
written approval of Operator, which shall not be unreasonably withheld.

     31.1 OPTION TO EXTEND: Upon completion of the Specified Contract Term,
Operator shall have the option, of extending the term of this Contract for the
period set forth in Item A-34, Exhibit A, upon Operator giving Contractor
written notice of its desire to extend the Contract on or before the time set
forth in Item A-35, Exhibit A, prior to expiration of the minimum Specified
Contract Term set forth in Item A-16, Exhibit A.

         The Specified Contract Term or any extension period (if such option is
exercised by Operator) shall be continued automatically from day to day for the
time necessary to complete the well or related operations in progress upon
expiration of the Specified Contract Term or any extension period.

     31.2 TERMINATION BY OPERATOR: Subject to the fulfillment of all then
existing obligations under this Contract and except as hereinafter provided,
Operator may terminate this Contract effective upon delivery to Contractor of
written notice of such termination:


          31.2.1 At any time after total or constructive loss of the drilling
                 unit (i.e. accident or other occurrence which renders the
                 drilling unit



                                       44
<PAGE>   45

                 permanently incapable of performing the work contemplated by
                 this Contract);

          31.2.2 At any time after the drilling unit becomes incapable of
                 performing the work contemplated by this Contract due to
                 circumstances within Contractor's control and Contractor fails
                 to make the unit capable of performing such work within sixty
                 (60) days following written notice of termination;

          31.2.3 At any time greater than one hundred eighty (180) days after
                 notice of Force Majeure, as set forth in Section 28.1 above;

          31.2.4 If Operator has provided written notice to Contractor that any
                 of the following has occurred and Contractor has failed to cure
                 same within ten (10) days thereafter, unless same is not
                 capable of cure within ten (10) days, in which case Contractor
                 shall diligently prosecute all corrective actions thereafter
                 until successfully completed: Contractor has failed to conduct
                 its operations under this Contract in accordance with good
                 oilfield practice, as a result of causes within the control of
                 Contractor; Contractor has failed to furnish or maintain
                 Contractor's Equipment in good condition and/or suitable for
                 the use intended; or Contractor has not removed from operations
                 under this Contract any of Contractor's Personnel or other
                 personnel which Operator considers to be incompetent or
                 otherwise detrimental to the normal operational efficiency of
                 Operator's drilling program; or



                                       45
<PAGE>   46

          31.2.5 At any time, for any reason other than as set forth in Sections
                 31.2.1-4 hereinabove, provided that Operator shall elect in
                 writing, within thirty (30) days after such termination notice
                 is issued, to pay Contractor under either of the following
                 provisions, as settlement in full for all of Contractor's
                 damages and other costs, and for all other liabilities which
                 Operator may have to Contractor, arising directly or indirectly
                 out of such termination by Operator:

                     (a) Pay Contractor a lump sum fee equal to the net present
                 value (calculated to the date of payment) of the Contract. The
                 net present value shall be calculated by multiplying the
                 Operating Rate in Exhibit "A-22" by the number of days
                 remaining in the Specified Contract Term at the time of
                 Operator's payment and applying a 7.5% discount rate which
                 assumes a rig use at the mid-point of each remaining year for
                 the number of applicable days of required rig utilization for
                 that year. Example: Operator provides notice to terminate in
                 year 2004 and has utilized the rig for a cumulative total of
                 365 days by the end of year 2003. The net present value
                 calculation will be for a remaining 91.25 days and an assumed
                 rig utilization at mid-year where one-half of the remaining
                 days are before July 1 of that year and one-half are after July
                 1.

                     (b) Pay the Standby Without Crew Rate as applicable from
                 the date of termination notice until the earlier of (i) the
                 expiration of the remainder of Operator's Specified Contract
                 Term or (ii) the



                                       46
<PAGE>   47

                 drilling unit commences operations for, and Contractor is
                 entitled to receive, equal payments from another party for the
                 remainder of the Specified Contract Term. In the event the
                 Operator elects to terminate pursuant to this paragraph (b),
                 Contractor shall exert every reasonable effort to find
                 alternate employment for the drilling unit. In the event
                 Contractor, with Operator's approval, is able to secure a
                 contract with another party for the remaining balance of the
                 Specified Contract Term, or for a portion thereof, at an
                 operating rate less than that provided for in this Contract,
                 the difference of the two rates will be payable by Operator to
                 Contractor under this Section 31.2.5 (b) for the duration of
                 the Specified Contract Term, and if such other contract(s)
                 terminates prior to the end of the Specified Contract Term,
                 Operator shall pay Contractor the Stand-by Without Crew Rate
                 for such portion of the remaining Specified Contract Term that
                 the drilling unit is not under another contract. Contractor
                 shall invoice Operator on a monthly basis for any remaining
                 payments due under this Section 32.2.5(b), subject to
                 Operator's audit rights under Section 20.1. Operator's
                 remaining Specified Contract Term shall be deemed to run as per
                 the Drilling Slot rotation set forth in Section 2.3 and
                 assuming a rig use at the mid-point of each year for the number
                 of days or required rig utilization for that



                                       47
<PAGE>   48

                 year (unless modified by mutual agreement of Operator,
                 Contractor and other sharing parties) for the purposes of
                 determining Operator's payment obligation to pay Contractor the
                 Standby Without Crew Rate, less any applicable offsets
                 (pursuant to the calculation procedure in the preceding
                 paragraph) for those portions of days in Operator's remaining
                 Drilling Slots in which the rig is utilized pursuant to third
                 party contracts subsequently entered into by Contractor.

          In the event Operator terminates this Contract in accordance with
Sections 31.2.1, 2, 3 or 4 above, such termination shall be without penalty to
Operator, and Contractor shall not be entitled to any early termination
compensation. Contractor shall be paid all compensation earned prior to the
termination date and also the demobilization rate set forth in Item A-21. If
Operator terminates this Contract pursuant to Section 31.2.5 (a) or (b), the
payment made thereunder by Operator to Contractor shall be deemed liquidated
damages, and not a penalty, and shall constitute settlement in full of all
claims whatsoever which Contractor may have against Operator arising out of such
termination, except that Operator shall remain responsible for payment of the
demobilization rate set forth in Item A-21 and also all liabilities which
Operator incurred hereunder prior to such termination.

          To the extent of any conflict between the provisions of this Section
and the terms and provisions of the remainder of this Contract, the provisions
of this Section shall control.

     31.3 TERMINATION BY CONTRACTOR: Subject to the provisions of Section 20.1,
in the event that any payments due (except any invoices that are in dispute or
in the



                                       48
<PAGE>   49

process of being settled) are not paid when due, Contractor shall notify
Operator of nonpayment and shall give Operator twenty (20) days from receipt of
said notice to pay. In the event Operator fails to pay within said twenty (20)
day period, Contractor may terminate this Contract by notifying Operator in
writing to that effect and the Contract shall terminate thirty (30) days after
receipt of the latter notice, unless payment of all invoices then overdue and
not in dispute is received by Contractor prior to the expiration of said thirty
(30) day period. In the event the Contract is terminated pursuant to this
Section, Contractor shall be under no obligation to finish any well or work in
progress.

     32.1 UNSATISFACTORY PERFORMANCE: If Contractor has failed to conduct its
operations under this Contract in accordance with good oilfield practice as a
result of causes within the control of Contractor, or Contractor has failed to
furnish or to maintain Contractor's Equipment in good condition and/or suitable
for the use intended, or members of Contractor's Personnel or other personnel
engaged by Contractor are considered by Operator to be incompetent or otherwise
detrimental to Operator's drilling program, Operator may give Contractor written
notice of default, specifying Contractor's performance failures or deficiencies.
Should Contractor fail or refuse to remedy the matters complained of within ten
(10) days after its receipt of such written notice (unless such matter is not
capable of cure within ten (10) days, provided that Contractor shall diligently
prosecute all corrective actions thereafter until successfully completed),
Operator may (i) terminate this Contract with no penalty or early termination
compensation as provided in Section 31.2.5 above or (ii) take over the exclusive
operation of Contractor's Equipment and Personnel for the purpose of conducting
operations hereunder, notwithstanding anything to the contrary contained in this
Contract, excepting only the required approval of Contractor's underwriter,



                                       49
<PAGE>   50

which shall not be unreasonably withheld. In the event operations are taken over
by Operator:

              32.1.1 Operator shall pay Contractor the Stand-By Without Crew
                     Rate set forth in Item A-25, Exhibit A, plus the value of
                     any drilling supplies belonging to Contractor and used by
                     Operator for the period of such operations by Operator;

              32.1.2 Operator shall pay all costs and wages (but not handling
                     charges) in connection with Contractor's Equipment and
                     Personnel;

              32.1.3 Operator shall return Contractor's Equipment to Contractor
                     in as good condition as when taken over by Operator, normal
                     wear and use excepted; and

              32.1.4 All operations shall be at Operator's risk, and any
                     representations and indemnity provisions of this Contract
                     whereby Contractor undertakes to protect, indemnify,
                     release, defend or to hold harmless Operator, in any
                     respect (other than Patent Liability set forth in Section

                     such protection, indemnity, release, defense or hold
                     harmless provisions shall survive and be applicable to the

No failure or failures on the part of either Party to enforce, from time to
time, all or any portion of the terms or conditions of this Contract shall be

applicable, shall apply to this Contract.

     36.1 BANKRUPTCY: Should Contractor become insolvent or make an assignment

prohibition on: the use, possession, or transportation of firearms, alcoholic
beverages, illegal drugs, narcotics, or other controlled dangerous substances,
and unauthorized drugs for which a person does not have a current prescription
while on the Work Premises. The term "Work Premises" is used in its broadest
sense to include all work locations, buildings, structures, installations, rigs

point of debarkation, pursuant to the Search and Seizure Procedure attached
hereto and incorporated herein by reference as Exhibit "G".

     Violation of the above policy or refusal to submit to an inspection by any
individual will be cause for immediate removal of the individual from the Work
Premises and/or Contractor's drilling unit, as applicable.

         38.1 CHOICE OF LAWS: THIS CONTRACT SHALL BE CONSTRUED AND INTERPRETED
IN ACCORDANCE WITH THE GENERAL MARITIME LAWS OF THE UNITED STATES, EXCEPTING AS

APPLICABLE TO ANY PORTION OF THE WORK WHICH IS HEREUNDER, THE LAWS OF THE STATE
OF TEXAS SHALL APPLY.

         IN WITNESS WHEREOF, the undersigned Parties have executed this
Agreement effective as of the date first hereinabove written.

                            SEARCH AND SEIZURE POLICY

     This Exhibit is attached to and made a part of that certain Daywork
Drilling Contract dated January 1, 2000, by and between Union Pacific Resources
Company, as Operator, and Noble Drilling (U.S.) Inc., as Contractor.

     It is the Exploration and Production Offshore policy of Union Pacific
Resources Company ("Company") to maintain a work environment that is safe for
all employees and others and conducive to maintaining high work standards. As
part of this policy, no illegal drugs, intoxicating beverages, explosives,
firearms or other weapons are allowed on the facilities operated by or
contracted to Company. Illegal drugs include marijuana and all other controlled
substances not prescribed by a licensed physician for use by the person
possessing them. All Company employees, contractors and visitors should be aware
of, and must comply with, this policy.

     As a further safety precaution, entry into or remaining upon Company
facilities is conditioned upon the Company's right to search the person and
personal effects of the individual for illegal drugs, intoxicating beverages,
explosives, firearms or other weapons or unauthorized possession of Company
property. These searches may be made without warning and may include lockers,
rooms and work stations on any offshore platform or other work area operated by
the Company, if appropriate. Searches may also be made on departure from any
Company facility.

     Drug screening may be conducted on persons seeking access to or who are on
Company property. Drug screening is a scientific analysis of urine samples. The
analysis will be performed by authorized laboratory technicians. Samples will be
requested by an authorized Company representative.

     Prior to any search or screening, employees, contract personnel and third
Parties seeking admission to or from Company facilities will be requested to
sign a form stating that they understand the drug screening and search policy
and consent to it.

     Employees and non-employees have the right not to be searched or submit to
the drug screening. However, refusal of an employee to submit to a search or
drug screening will be cause for disciplinary action up to and including
immediate discharge. In all cases of a refusal to consent to a search and/or
drug screening, the responsible supervisor will arrange for the refusing person
to be removed immediately from Company property. Non-employees refusing to allow
a search or drug screening will not be allowed entry on Company property.

     Prohibited items discovered through these Company searches may be taken
into custody and may be turned over to the proper law enforcement authorities,
if appropriate.

     This policy is in effect at all Company offshore drilling and production
facilities as well as any Company warehouse or shorebase facility.
