                       SANTA FE INTERNATIONAL CORPORATION
            NOTES TO THE UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS
                                 MARCH 31, 2000


NOTE 1 - BASIS OF PRESENTATION AND DESCRIPTION OF BUSINESS

         Santa Fe International Corporation (the "Company"), a Cayman Islands
corporation, is a majority-owned subsidiary of SFIC Holdings (Cayman), Inc.
("Holdings"), which in turn is a wholly-owned subsidiary of Kuwait Petroleum
Corporation ("KPC"). KPC is wholly-owned by the State of Kuwait. The Company
owns and operates a high quality, technologically advanced fleet of 27 marine
and 33 land drilling rigs and provides drilling related services to the
petroleum industry worldwide.

         Holders of Ordinary Shares are entitled to participate in the payment
of dividends in proportion to their holdings. Under Cayman Islands law, the
Company may pay dividends or make other distributions to its shareholders, in
such amounts as the Board of Directors deems appropriate from the profits of
the Company or out of the Company's share premium account (equivalent to
additional paid-in capital) if the Company thereafter has the ability to pay
its debts as they come due. Cash dividends, if any, will be declared and paid
in U.S. dollars. At March 31, 2000, the Company had declared dividends that had
not been paid amounting to $3,735,000.

         The accompanying consolidated financial statements are presented in
U.S. dollars and in accordance with accounting principles generally accepted in
the U.S. The preparation of interim financial statements requires management to
make estimates and assumptions that affect the amounts reported in the
financial statements and accompanying notes. While management has based its
assumptions and estimates on facts and circumstances currently known, actual
amounts may differ from such estimates.

         The condensed consolidated financial statements included herein have
been prepared without audit, pursuant to the rules and regulations of the U.S.
Securities and Exchange Commission. Certain information and notes normally
included in financial statements prepared in accordance with generally accepted
accounting principles have been condensed or omitted pursuant to such rules and
regulations.

         The financial statements reflect all adjustments which are, in the
opinion of management, necessary for a fair statement of the results for the
interim periods. Such adjustments are considered to be of a normal recurring
nature unless otherwise identified. Results of operations for the three month
period ended March 31, 2000 are not necessarily indicative of the results of
operations that will be realized for the year ending December 31, 2000. These
financial statements should be read in conjunction with the audited financial
statements and the notes thereto included in the Company's Annual Report on
Form 20-F for the year ended December 31, 1999.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Cash Equivalents and Marketable Securities

         Cash equivalents consist of highly liquid short-term investments that
are readily convertible into cash and which at the date of purchase were so
near their maturity that they expose the Company to an insignificant risk from
changes in interest rates. Cash equivalents are carried at cost plus accrued
interest, which approximates fair value. The interest method is used to account
for any premium or discount on cash equivalents. The Company's policy is to
place its temporary cash investments with high credit quality financial
institutions and by policy limit the amount of credit exposure to any one
financial institution.

         The Company's marketable securities are classified as
available-for-sale securities. Unrealized holding gains and losses on
available-for-sale securities are included as a component of other comprehensive
income in shareholders' equity, net of the tax effect. The fair values for
marketable securities are based on quoted market prices. The amortized cost of
debt securities in this category is adjusted for amortization of premiums and
accretion of discounts to maturity. Such amortization is included in investment
income. Realized gains and losses and declines in value judged to be
other-than-temporary on available-for-sale securities are included in investment
income. The Company does not believe that it is exposed to any significant risks
on its investments.





                                       6
<PAGE>   7



         At March 31, 2000, marketable securities consisted primarily of
Eurodollar debt securities and commercial paper. Cost approximates market
value.

Income Per Ordinary Share

         The basic and diluted income per Ordinary Share data for the three
months ended March 31, 2000 and 1999, respectively, is calculated based on the
weighted average shares outstanding for the periods.

Comprehensive Income

         The Company accounts for comprehensive income in accordance with
Statement of Financial Standards ("SFAS") No. 130, "Reporting Comprehensive
Income" which establishes standards for reporting and display of comprehensive
income and its components. Comprehensive income is defined as the change in
equity of a business enterprise during a period from transactions and other
events and circumstances from nonowner sources. For the three month periods
ended March 31, 2000 and 1999, respectively, the Company realized no such
transactions other than those reported in net income.

NOTE 3 - COMMITMENTS AND CONTINGENCIES

         In the normal course of business, the Company is involved in various
lawsuits, claims and related matters. In the opinion of management, the
ultimate resolution of such matters will not have a material adverse effect on
the consolidated financial position or results of operations of the Company.

NOTE 4 - INCOME TAXES

         The Company is not subject to income taxes in the Cayman Islands. All
of the Company's income before provision for taxes on income and the related
provision for taxes on income relates to operations in jurisdictions other than
the Cayman Islands. The relationship between income before provision for taxes
on income and the provision for taxes on income varies from period to period
because each jurisdiction in which the Company operates has its own system of
taxation (not only with respect to the nominal rate, but also with respect to
the allowability of deductions, credits and other benefits) and because the
amounts earned in, and subject to tax by, each jurisdiction varies from period
to period. The provisions for taxes on income for the three month periods ended
March 31, 2000 and 1999, respectively, were recognized based upon the expected
annualized relationship.

NOTE 5 - SEGMENT INFORMATION

         The Company currently has six reportable segments, defined as
different equipment classifications, or by contract terms in the case of
drilling related services, as follows: heavy duty harsh environment jackup
rigs, semisubmersible rigs, 300 to 350 foot cantilever jackup rigs, 200 to 250
foot jackup rigs, land rigs and drilling related services. In past periods, the
Company's platform rig and inland lake barge were combined and reported as an
additional reportable segment, "other marine rigs".




                                       7
<PAGE>   8

         The Company evaluates performance and allocates resources based upon
the operating margin (operating revenues less operating expenses) generated by
the segment. For further details of operating margin by segment, see "Item 2. -
Management's Discussion and Analysis of Financial Condition and Results of
Operations." There are no intersegment sales and transfers due to the nature of
the business of the segments. The following table sets forth operating revenue
and segment income for each of the reportable segments and reconciles total
segment income to consolidated income before provision for taxes on income.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS

         The statements regarding future performance and results and the other
statements that are not historical facts contained in this report are
forward-looking statements. Statements made in this document that state the
Company's or management's intentions, hopes, plans, estimates, beliefs,
expectations, anticipations or predictions of the future and words of similar
import are "forward-looking statements" within the meaning of the Private
Securities Litigation Reform Act of 1995. Although the Company believes that
the expectations reflected in such forward-looking statements are reasonable,
it can give no assurance that such expectations will prove to have been
correct. Such statements involve risks and uncertainties including, but not
limited to, the risks involved in dealing with other parties, including the
risk that other parties' commitments to the Company and its subsidiaries could
be breached, changes in the markets for oil and natural gas and for drilling
rigs and the risks of doing business in changing markets and changing costs and
other factors discussed herein and in the Company's other Securities and
Exchange Commission filings. Should one or more risks or uncertainties
materialize, or should underlying assumptions prove incorrect, actual outcomes
may vary materially from those indicated.

         The contract drilling industry is and historically has been highly
volatile, competitive and cyclical, with periods of high demand and rig
utilization resulting in high rig dayrates followed by periods of low demand,
excess rig supply and low rig dayrates. The contract drilling business is
influenced by many factors beyond the control of the Company, including the
current and anticipated prices of oil and natural gas and client oil company
capital programs. During the depressed oil price cycle of late 1998 and early
1999, the oil and gas industry continued its trend toward consolidation, with
the announcement or completion of several merger and acquisition transactions.
Although oil prices have rebounded from the lows of the first quarter of 1999,
oil and gas industry capital spending levels for exploration and production
projects have been and may continue to be less robust than might have otherwise
been experienced without industry consolidation. As oil and gas companies
continue to address the impact of consolidation, their requirements for
drilling rigs and services may be adversely affected.

         In addition to consolidation within the oil and gas industry, the
contract drilling industry continued to experience merger and acquisition
activity. Further drilling industry consolidation could adversely impact the
Company's results of operations through lowered operating margins, increased
competition from larger industry members or a variety of other factors that
cannot as yet be identified or quantified.

         Oil prices recovered beginning in the second quarter of 1999 and
recently were at near record levels. The contract drilling industry is now
beginning to recover from the 1999 down cycle that resulted in reduced
worldwide rig utilization and depressed rig rates. To date, this recovery has
yielded increased offshore rig utilization and dayrates primarily in the Gulf
of Mexico. International offshore and land rig drilling markets (including
those in which the Company operates) have yet to enter into a meaningful
recovery and the Company presently has a number of rigs idle. The Company
believes the decreased utilization and lower dayrate trends recently
experienced by the industry will be reversed as the industry continues to
rebound. Although the price of crude oil increased through the last half of
1999 and remained strong during the first quarter of 2000, the potential impact
of this oil price increase on the Company's future results of operations, both
as to amount and timing, cannot be accurately predicted. The Company believes,
however, that higher oil and natural gas prices for an extended period of time
may result in increased oil and gas company exploration and production budgets,
which in turn may result in increased future demand for drilling rigs.

QUARTERS ENDED MARCH 31, 2000 AND 1999

         OPERATING REVENUES. Total operating revenues decreased $53.0 million
(28.6%). Revenues from the Company's heavy duty harsh environment jackup rig
fleet increased $10.1 million (22.4%) primarily due to the impact of Galaxy III
operations, which began on December 5, 1999 ($14.2 million). Partially
offsetting this increase were lower utilization ($3.0 million), primarily for
the Monitor, and lower average dayrates ($1.1 million). Operating revenues for
the Company's semisubmersible rigs decreased $23.6 million (81.5%) mainly due
to idle time incurred for Rig 135 and the Aleutian Key ($19.8 million) and a
45.0% decrease in average dayrates ($3.8 million). Revenues from 300-350 foot
cantilever jackups decreased $20.4 million (59.8%) primarily because of a 52.9%
decrease in average dayrates ($16.3 million) and decreased utilization of rigs
in Egypt and Saudi Arabia ($5.2 million), partially offset by increased
utilization of the Galveston Key in Indonesia ($1.1 million). Revenues from
200-250 foot jackup rigs decreased $6.4 million (30.7%), mainly due to a 42.1%
decrease in average dayrates ($8.2 million), lower utilization of Rig 103 in
Qatar ($2.0 million) and the idling of Rig 134 as it was upgraded during the
first quarter of 2000 ($1.9 million). Increased utilization ($5.7 million) of
rigs in Egypt and for Rig 127 in Qatar partially offset these decreases.
Revenues from drilling related services decreased $12.6 million (58.9%),
primarily because of a $6.7 million decrease in revenues from incentive
contracts and a $6.1 million decrease in third party rig operations, partially
offset by $0.3 million in revenues from the Company's platform rig. Revenues
from both incentive drilling and third party rig operations decreased mainly
due to lower activity in the North Sea.

         OPERATING COSTS. Total operating costs decreased $4.9 million (5.2%).
Operating expenses from heavy duty harsh environment jackup rigs increased $2.9
million (20.4%) primarily due to the impact of Galaxy III operations.
Semisubmersible rig operating costs increased $2.5 million (23.0%) primarily
due to maintenance costs incurred on Rig 135 and on the Aleutian Key while
idle. Operating costs for the 200-250 foot jackups rigs increased $1.4 million
(11.8%), primarily due to increased utilization. Operating expenses from
drilling related services decreased $9.6 million (61.1%) primarily due to a
$6.3 million decrease in expenses associated with incentive drilling contracts
and a $3.2 million decrease in expenses from third party operations. Other
operating expenses decreased $1.6 million (44.7%), primarily due to decreased
provision for inventory obsolescence.

         GENERAL AND ADMINISTRATIVE. General and administrative expense
decreased $1.1 million (20.6%) primarily due to lower employee benefit costs.

         DEPRECIATION AND AMORTIZATION. Depreciation and amortization expense
increased $2.7 million (15.3%) for the quarter ended March 31, 2000 as compared
with the same period in the prior year. Addition of the Galaxy III marine rig
and Rig 180 land rig increased depreciation expense by $1.7 million and $0.4
million, respectively. The remainder of the increase was due to depreciation of
general capital additions to all other rigs and equipment.

         OTHER INCOME (EXPENSE), NET. Other income increased $2.1 million for
the quarter ended March 31, 2000, mainly due to increased investment income,
primarily due to higher invested balances.

         PROVISION FOR TAXES ON INCOME. The provision for taxes on income
decreased $7.3 million (65.2%) for the first quarter of 2000 as compared with
the same quarter of 1999. The Company's expected annualized effective tax rate
will increase to 17.6% in 2000 from 16.1% in 1999 due to changes in the mix of
reportable earnings generated within the various taxing jurisdictions in which
the Company operates.

         NET INCOME. Net income for the quarter ended March 31, 2000 decreased
$40.2 million (68.7%) to $18.3 million as compared to $58.5 million for the
same period in the prior year. This decrease resulted primarily from $53.0
million decreased operating revenues and $2.7 million increased depreciation
and amortization expense, partially offset by decreased operating expense of
$4.9 million, $2.1 million higher other income (expense), net, decreased
general and administrative expense of $1.1 million and $7.3 million decreased
provision for income taxes.

LIQUIDITY AND CAPITAL RESOURCES

         Net cash provided by operating activities was $25.3 million and $61.4
million for the three months ended March 31, 2000 and 1999, respectively. The
decrease in cash flows from operations was primarily attributable to changes in
income before non-cash charges. Investing activities provided cash of $125.0
million for the three months ended March 31, 2000 and used cash of $89.5
million for the corresponding period in 1999. The $214.5 million increase in
cash provided by investing activities was primarily due to $184.9 million
increased net maturities and purchases of marketable securities and lower
capital spending of $29.5 million. Capital expenditures totaled $8.7 million
and $38.3 million for the three months ended March 31, 2000 and 1999,
respectively, principally related to rig upgrades and modernization in both
periods and rig expansion in 1999. For the three months ended March 31, 2000,
capital expenditures on the heavy duty harsh environment jackup rig Galaxy III
decreased $21.9 million and spending for new land rigs decreased $5.0 million
compared to the corresponding period in 1999. Maturities and purchases of
marketable securities for the three month periods were primarily for Eurodollar
debt instruments and commercial paper with original maturities of more than 90
but less than 365 days. For the three months ended March 31, 2000 and 1999,
cash used in financing activities was $1.8 million and $1.6 million,
respectively. Dividends paid to shareholders amounted to $3.7 million in each
period, partially offset by issuance of shares under the Company's Employee
Share Purchase Plan in January 2000 and 1999 of $1.9 million and $2.1 million,
respectively.

         The Company budgeted approximately $150 million for capital
expenditures during the year ending December 31, 2000. Capital spending to meet
contractual obligations for customers and for rig upgrade, modernization and
enhancement projects is budgeted to require approximately $60 million,
representing numerous individual transactions spread over the course of the
year. Further, the Company budgeted $50 million intended for use in either
constructing or acquiring one or more new rigs, based upon market conditions.
Finally, in anticipation of favorable contract negotiations with oil companies
operating in Azerbaijan, $40 million was budgeted for anticipated equipment
upgrades to the semisubmersible Dada Gorgud. Such negotiations have now been
successfully concluded, and the Company will be operating the rig under an
approximate six-year drilling contract. In order to meet the contract
specifications required, the Company now estimates spending approximately $30
million for capital improvements to the Dada Gorgud in 2000, the cost of which
will be recovered through operating dayrates following completion of the
upgrade. It is expected that the entire 2000 capital program will be funded
from internally generated funds. Future capital spending, particularly rig
fleet additions, is subject to the Company's prospects for securing appropriate
drilling contract opportunities and the availability of suitable rigs, rig
components, construction facilities and supplies.

         From time to time, the Company reviews opportunities for rig
acquisition, construction or upgrade. Once the Company undertakes a capital
project, factors outside the Company's control, such as changes in market
demand, may alter the project economics and the Company may be unable to fully
recoup the cost of such expenditures through future drilling contracts. At any
time, should plans for rig acquisition, construction or upgrade not be
completed, the Company would not have those rigs available to compete in its
markets.

         On March 7, 2000, the Company's Board of Directors declared a regular
quarterly dividend of $0.0325 per Ordinary Share payable on April 17, 2000 to
holders of record at the close of business March 31, 2000. The Company's
current dividend policy contemplates payment of future quarterly dividends of
$0.0325 per Ordinary Share.

         The Company's principal source of funds has been cash flow from
operations. The Company believes available cash resources and cash flows from
operations will be sufficient to meet its capital requirements during 2000.

         The Company currently has a $35 million uncommitted credit facility
for advances and letter of credit with a major bank, none of which was drawn or
subject to standby letters of credit at March 31, 2000.

CURRENCY RISK AND INFLATION

         The Company conducts material business operations in foreign currency
environments. The Company generally attempts to minimize its currency exchange
risk by seeking international contracts payable in local currency in amounts
equal to the Company's estimated operating costs payable in local currency and
in dollars for the balance of the contract. Because of this strategy, the
Company has minimized its net asset or liability positions denominated in local
currencies and has not experienced significant gains or



                                      12
<PAGE>   13


losses associated with changes in currency exchange rates. Accordingly, the
Company has not historically entered into financial hedging arrangements to
manage risks relating to fluctuations in currency exchange rates. However, the
Company may enter into such contracts in the future in the event that the
Company assumes significant foreign currency risks.

         Although inflation has not had a significant impact on the Company's
results of operations during the past several years, labor availability and
cost and vendor prices and delivery fluctuate in response to overall drilling
industry conditions.

CREDIT RISKS

         The Company's customers consist primarily of major international,
state owned and large independent oil companies and their affiliates. The
Company has not incurred any charges for credit losses during the last five
years. There is no assurance that in the future such charges will not occur.
Such charges may adversely affect the Company's profitability.

OTHER

         Operational risks and hazards may result in extensive damage to or
total loss of drilling rigs, with associated personal injuries and loss of
life, pollution, well loss, well control expenses and/or wreck removal or other
requirements. Such losses, liabilities or obligations may be uninsured or
underinsured. In the event of a major incident or incidents resulting from
operational risks and hazards, the Company will sustain a loss of revenue by
reason of the rig loss or damage and may be subject to extraordinary expenses
in respect of uninsured or underinsured losses, liabilities or obligations.

         The Company's worldwide operations are subject to numerous foreign,
U.S., state and local environmental laws and regulations that relate directly
or indirectly to its operations, including certain regulations controlling the
discharge of materials into the environment, requiring removal and clean-up
under certain circumstances, or otherwise relating to the protection of the
environment. Laws and regulations protecting the environment have become
increasingly stringent in recent years and may in certain circumstances impose
a strict liability and render a company liable for environmental damage without
regard to negligence or fault on the part of such company. Such laws and
regulations may expose the Company to liability for the conduct of or
conditions caused by others, or for acts of the Company that were in compliance
with all applicable laws at the time such acts were performed.

         The Company operates each of its rigs under a contract either to drill
a specified well or number of wells or for a stated period of time, which
generally is automatically extended to include the period required to complete
the well in progress on the scheduled contract expiration date. Contracts often
are cancelable upon specified notice at the option of the customer, and some,
but not all, contracts provide for the customer to pay a specified early
termination payment in the event of such cancellation. The contracts
customarily provide for either automatic termination or termination at the
option of the customer in the event of total loss of the drilling rig or if
drilling operations are suspended for extended periods by reason of force
majeure or excessive rig downtime for repairs. The contracts also contain
provisions addressing automatic termination or termination at the option of the
customer in certain circumstances and may be dishonored or subject to
renegotiation in depressed market conditions.

         The Company's liquidity also may be adversely impacted by reason of
war, political turmoil, revolution, insurrection or similar events which could,
inter alia, result in damage to or loss of the Company's rigs, either
physically or by reason of nationalization, expropriation or deprivation of
use, or could impair the concessionary rights of the Company's customers, thus
jeopardizing the Company's drilling contracts. The Company does not normally
insure against these risks, and such events could result in an actual or
constructive loss of substantial assets and the associated loss of revenues
and/or receivables.

IMPACT OF YEAR 2000

         The Company's successfully implemented Y2K initiative spanned a period
of three years and cost approximately $3 million. Our worldwide operations were
prepared to overcome any failures experienced during the millennium rollover
and leap year periods. To date, the Company has experienced no disruption.
However, contingency plans will remain in effect throughout 2000 as
circumstances dictate.

         DRILLING SERVICES as aforesaid.

         In the context of this sub-clause 5.2 the constructive, compromised or
         arranged total loss of the DRILLING UNIT shall mean the constructive,
         compromised or arranged total loss of the DRILLING UNIT under
         applicable insurance policies or arrangements as otherwise agreed to by
         the Parties.

                          CLAUSE 6 ACCESS TO LOCATIONS

The OPERATOR shall secure for the CONTRACTOR and its SUB-CONTRACTORS rights of
access to and from LOCATIONS. All LOCATIONS shall be surveyed by OPERATOR at its
own cost, such survey being subject to any approval by surveyors which may be
required under applicable marine insurance. The OPERATOR shall use its best
endeavors to advise the CONTRACTOR in writing of the presence of any obstacles
and obstructions and any limitations, restrictions or conditions associated
therewith which may affect such access and the CONTRACTOR shall abide by such
written limitations, restrictions and conditions. OPERATOR and CONTRACTOR shall
meet and agree whether such limitations, restrictions or conditions prevent the
DRILLING UNIT from safely moving or operating on the LOCATION. In the event it
is agreed by the Parties that the DRILLING UNIT cannot be safely moved to or
operated on the LOCATION, CONTRACTOR shall be paid the OPERATING RATE until such
time as the DRILLING UNIT can be safely moved to or operated on the LOCATION.
While CONTRACTOR is unable to safely move to or operate on the LOCATION the
OPERATOR may instruct the CONTRACTOR to remain on standby near the LOCATION or
move to a new location and the appropriate rate as set out in Exhibit "5" shall
be payable.

Notwithstanding any other provision of the CONTRACT, or the results of any
survey or the approval of such survey by marine insurance surveyors, OPERATOR
shall indemnify, defend and hold the CONTRACTOR GROUP harmless from and against
any and all liability, claims,

demands, suits, expenses and causes of action arising in any manner for damage
to or destruction of any such obstacles or obstructions, provided that the
defense, indemnity and hold harmless obligation contained in this clause 6 shall
not apply if the damage to or destruction of any such obstacle or obstruction is
caused by CONTRACTOR's failure to abide by such written limitations,
restrictions and conditions associated with such obstacles and obstructions.

As used herein, obstacles and obstructions shall mean and include, by way of
illustration, flowlines, pipelines wellheads, platforms, subsea installations,
wreckage and debris at, or in proximity to, drilling locations or routes of
access thereto or therefrom.

                                CLAUSE 7 DEFAULT

7.1      Unsatisfactory Performance by the CONTRACTOR

         In the event that the OPERATOR is dissatisfied with the performance of
         the CONTRACTOR based upon any one of the following reasons:

         (i)    unreasonably slow progress of CONTRACTOR;

         (ii)   incompetence of CONTRACTOR;

         (iii)  default by CONTRACTOR in the performance of its obligations
                under the CONTRACT; or

         (iv)   any other reason as a result of causes reasonably within the
                CONTRACTOR's control, the OPERATOR shall notify the CONTRACTOR
                in writing as to the cause of its dissatisfaction.

         Should the CONTRACTOR fail to remedy the matters so specified within a
         period of not more than seven (7) days (or if it is not possible to
         remedy such matters within seven (7) days and CONTRACTOR has failed to
         initiate and diligently pursue corrective action within such seven (7)
         day period to the reasonable satisfaction of OPERATOR), the OPERATOR
         may exercise one of the following rights:

         (a)      immediately terminate the CONTRACT in which case no further
                  payments shall be due to the CONTRACTOR other than those
                  outstanding for work done prior to termination together with
                  the appropriate Early Termination Fee. In such event,
                  CONTRACTOR shall not be entitled to have the DRILLING UNIT
                  demobilised at OPERATOR's expense;

         (b)      continue the current operation and such other operations as
                  set forth in Clause 7.2 herein; or

- --------------------------------------------------------------------------------


         (c)      terminate the CONTRACT upon completion of the current
                  operation then being performed at the time of receipt of the
                  notification of dissatisfaction as aforesaid in which case no
                  further payments shall be due to the CONTRACTOR other than
                  those outstanding for work done prior to termination together
                  with the appropriate Early Termination Fee. In such event,
                  CONTRACTOR shall not be entitled to have the DRILLING UNIT
                  demobilised at OPERATOR's expense.

         The OPERATOR's remedies under subclauses 7.1(a) (b) and (c) shall be
         OPERATOR's exclusive remedies against CONTRACTOR with respect to the
         matters set forth in this clause 7.1 herein; provided, however, that if
         CONTRACTOR willfully and materially or otherwise materially defaults in
         the performance of its obligations under the CONTRACT the OPERATOR's
         remedies under subclauses 7.1(a) (b) and (c) shall not be OPERATOR's
         exclusive remedies against CONTRACTOR with respect to the matters set
         forth in this clause 7.1.

7.2      Continuation of Operations by OPERATOR

         If OPERATOR so elects to continue operations in accordance with Clause
         7.1 herein, the OPERATOR may continue operations hereunder either by
         taking possession of and using the CONTRACTOR's EQUIPMENT and that of
         the SUBCONTRACTORs and all things connected therewith and using the
         CONTRACTOR's PERSONNEL and SUBCONTRACTOR's personnel and repossessing
         any OPERATOR's MATERIALS then unconsumed and if it so elects by either
         of the following:

         (i)      completing the current operation and such other operation or
                  operations contemplated by the OPERATOR hereunder by the
                  aforesaid means; or

         (ii)     completing the current operation and such other operations as
                  aforesaid by the use of another contractor to operate the
                  CONTRACTOR's EQUIPMENT. During the conduct of all such
                  operations by or on behalf of the OPERATOR incurring the use
                  of the CONTRACTOR's PERSONNEL and SUBCONTRACTOR's personnel
                  aforesaid the CONTRACTOR shall be responsible for the payment
                  of all its PERSONNEL, for any replacement therefor and for
                  procuring their obedience to the OPERATOR's instructions. The
                  CONTRACTOR shall continue to make payments due to its
                  SUBCONTRACTORs and suppliers as well as for insurance
                  premiums. Except for CONTRACTOR's payment obligations set
                  forth in this sub-clause 7.2(ii) all such operations shall be
                  at the sole risk of the OPERATOR and the CONTRACTOR GROUP
                  shall be under no liability during such operations for

                  SUBCONTRACTOR's personnel.

         For all such operations carried out by the OPERATOR under this
         sub-clause 7.2 the CONTRACTOR shall be entitled to be paid for work in
         accordance with the terms of the CONTRACT less expenditure necessarily
         incurred by the OPERATOR in carrying out the aforesaid operations in
         respect of the CONTRACTOR's EQUIPMENT, the CONTRACTOR's PERSONNEL or
         the use of staff and labour provided by another contractor and less
         sums due from the CONTRACTOR to any THIRD PARTY, the non-payment or
         non-expenditure of which jeopardises the continuance of the said
         operations (but excluding any payment due to the CONTRACTOR for the use
         of tools, machinery and appliances hired by it at the request of the
         OPERATOR), provided, however, the expenditures necessarily incurred by
         OPERATOR, for which CONTRACTOR shall hereunder be liable, shall not in
         any event be greater than the then current REDRILLING Rate under the
         CONTRACT. Upon completion of the aforesaid operations the OPERATOR
         shall return to the CONTRACTOR the CONTRACTOR's EQUIPMENT and the
         equipment of the SUBCONTRACTORs and any tools, machinery and appliances
         hired by it as aforesaid in as good condition as when taken over by the
         OPERATOR, fair wear and tear excepted.

7.3      CONTRACTOR's Failure to Provide the CONTRACTOR's EQUIPMENT

         In the event of the CONTRACTOR's failure to provide any of the
         CONTRACTOR's EQUIPMENT or in the event that the CONTRACTOR's EQUIPMENT
         fails to meet the applicable manufacturer's rating for such equipment
         (or such other rating that may otherwise be specified in Exhibit "7")
         so as to make operations unsafe or to reduce the efficiency thereof the
         OPERATOR shall notify the CONTRACTOR in writing specifying such
         CONTRACTOR's EQUIPMENT which the CONTRACTOR has so failed to provide or
         which fails to meet the said rating, and immediately thereafter the
         OPERATOR shall have the right to exercise one of the following options:

         (a)      shutdown such operations until such time as the CONTRACTOR
                  shall have made good the deficiencies in the said equipment
                  whether as to provision or to performance.

                  For any such period of shutdown the OPERATOR shall pay the
                  CONTRACTOR:

- --------------------------------------------------------------------------------


                  (i)      at the REPAIR RATE in accordance with Exhibit "5"
                           hereof provided the shutdown is due to an equipment
                           failure.

                  (ii)     REDUCED REPAIR RATE if the shutdown is due to unsafe
                           operations.

                  In all such instances referred to in (i) and (ii) above the
                  OPERATOR shall have the exclusive right to terminate the
                  CONTRACT any time after a shutdown period has exceeded seven
                  (7) days (or if it is not possible to remedy the deficiencies
                  in the equipment in such seven (7) day period and CONTRACTOR
                  has failed to initiate and diligently pursue corrective action
                  within such seven (7) day period to the reasonable
                  satisfaction of OPERATOR).

                  In the event of such termination, no further payments shall be
                  due to CONTRACTOR other than those outstanding for the work
                  done prior to termination together with the appropriate Early
                  Termination Fee. In such event, CONTRACTOR shall not be
                  entitled to have the DRILLING UNIT demobilised at OPERATOR's
                  expense. The remedies set forth herein shall be the exclusive
                  remedies of OPERATOR against CONTRACTOR only with respect to
                  the matters set forth in this clause 7.3 (a).

         (b)      to continue with operations at reduced efficiency as aforesaid
                  and in such event the OPERATOR shall have the right to reduce
                  the Rates and Charges in Exhibit "5" by an amount in direct
                  relation to the percentage that operations have in OPERATOR's
                  opinion been so reduced in efficiency or slowed down, provided
                  that if operations are so continued then the OPERATOR shall
                  assume liability for any loss of or damage to the hole arising
                  directly out of the continuing of operations with such reduced
                  efficiency and provided further that during such operations so
                  continued the CONTRACTOR shall continue to make good the
                  aforesaid failure.

         (c)      to hire from the nearest available source satisfactory to the
                  OPERATOR all such equipment as may be required:

                  (i)      arising out of the CONTRACTOR's failure so to provide
                           the DRILLING EQUIPMENT or any part thereof, until the
                           CONTRACTOR shall have provided as aforesaid, or

                  (ii)     arising out of failure of the DRILLING EQUIPMENT or
                           any part thereof to meet manufacturer's
                           specifications, or such other

                           the OPERATOR that the said equipment or part thereof
                           does meet such specifications.

                  All costs incurred by the OPERATOR in hiring and transporting
                  such equipment shall be a debt due to the OPERATOR from the
                  CONTRACTOR and shall be deducted from any monies due to the
                  CONTRACTOR from the OPERATOR.

                  monies due to the CONTRACTOR the cost of hire (from the
                  nearest available source) of equipment listed in the
                  CONTRACTOR's EQUIPMENT but not provided by it.

8.1      CONTRACTOR's EQUIPMENT and Property

         (a)      Except as may be provided for in Clauses 7.2, 8.1(b) and
                  8.1(c) herein, the CONTRACTOR shall release, defend, indemnify
                  and hold harmless the OPERATOR GROUP from and against any and
                  all liability, claims, demands, suits, expenses and causes of
                  action for any loss, damage, injury or destruction of the
                  CONTRACTOR GROUP's equipment and property, including
                  CONTRACTOR's EQUIPMENT whether arising in contract or in tort,
                  or any other theory of law, including but not limited to
                  strict liability, regardless of how such loss, damage or
                  destruction occurs, notwithstanding that such loss or damage
                  as aforesaid may have been due to the sole, concurrent, active
                  or passive negligence, or fault of OPERATOR GROUP or a defect
                  in the property or equipment of either Party, including but
                  not limited to those defects pre-existing the EFFECTIVE DATE
                  of this CONTRACT.

         (b)      Except as to fair wear and tear, the OPERATOR shall assume
                  liability at all times during the DRILLING SERVICES for loss
                  of or damage to the CONTRACTOR GROUP's in-hole equipment when
                  in the hole and Sub-sea Equipment while it is being operated
                  sub-sea (whether owned or rented) including loss or damage
                  resulting from exposure to H2S. The OPERATOR shall reimburse
                  the CONTRACTOR for the replacement cost less depreciation of
                  any such equipment so lost, and in respect of equipment so
                  damaged whichever shall be the lesser of the replacement
                  on-site cost less depreciation or the repair cost, provided,
                  however, that OPERATOR shall not reimburse the

                  CONTRACTOR for the loss of such equipment if such loss or
                  damage is due to the sole negligence and/or sole default of
                  the CONTRACTOR GROUP.

                  For purposes of this clause, sub-sea equipment shall include
                  CONTRACTOR's sub-sea equipment and mooring equipment including
                  but not limited to riser, slip joints, control hoses, blowout
                  preventers, anchors, anchor wires and chains, tripping lines
                  and buoys, (herein collectively called Sub-sea Equipment).

                  As to new equipment, depreciation shall be calculated monthly
                  from the COMMENCEMENT DATE or the date such equipment was
                  first placed in service (whichever is later) at two percent
                  (2%) per month for in-hole tools and one percent (1%) per
                  month for Sub-sea equipment. As to used equipment,
                  depreciation shall be calculated monthly from 1 June 1997 or
                  the date such equipment was first placed in service (whichever

                  one percent (1%) per month for Sub-sea equipment.

         (c)      Notwithstanding any other provision of the CONTRACT or any of
                  the Exhibits hereto: (i) nothing contained herein shall be
                  construed as in any way restricting CONTRACTOR's or its
                  underwriters' rights to recover against any vessel owner or
                  operator for damage to or loss of the DRILLING UNIT; and (ii)
                  OPERATOR GROUP shall not be entitled to any release, defence,
                  indemnity or hold harmless undertaking from CONTRACTOR under
                  clause 8.1 (a) for any claims which may be made against
                  OPERATOR by any vessel owner or operator (or their
                  underwriters) for damage or loss caused by such vessel owner

8.2      OPERATOR's MATERIALS and Property

         (a)      The CONTRACTOR shall take all reasonable precautions
                  (including but not limited to the making out of loading notes)
                  to protect and save from loss or damage items of the
                  OPERATOR's MATERIALS and materials of OPERATOR's contractors
                  and subcontractors while in the custody of the CONTRACTOR.
                  Subject to the provisions of clause 8.2(b) below, when no
                  longer required for operations hereunder the CONTRACTOR shall
                  return to the OPERATOR after use such of the said OPERATOR's
                  MATERIALS as have not been consumed, in the same condition as
                  when handed to the CONTRACTOR fair wear and tear excepted.

                           defend and hold harmless CONTRACTOR GROUP from and
                           against any and all such claims, demands,

         which may sink in the course of operations hereunder or otherwise deal
         with it in accordance with the OPERATOR's direction. In the event that
         the CONTRACTOR does not carry out these obligations the OPERATOR may
         buoy and light the sunken DRILLING UNIT or property and may remove it
         (without prejudice to the OPERATOR's rights) and in such event
         CONTRACTOR shall refund to the OPERATOR all costs so incurred. The fact
         that the sunken DRILLING UNIT or property is insured or has been
         declared a total loss shall not absolve the CONTRACTOR from its
         obligations to raise and/or remove same. This clause shall remain
         binding on the CONTRACTOR notwithstanding the termination of the
         CONTRACT for any reason.

8.7      Consequential Damages

         Notwithstanding any other provision in the CONTRACT, OPERATOR hereby

         or consequential damages resulting from or arising out of this
         CONTRACT, including, without limitation, loss of profits, loss of
         production or business interruption howsoever same may be caused,
         including that caused by the sole, joint and/or concurrent negligence,
         fault or strict liability of CONTRACTOR GROUP. Notwithstanding any
         other provision in the CONTRACT, CONTRACTOR hereby releases its claims
         against OPERATOR GROUP (which for purposes of this Clause 8.7 shall
         include OPERATOR's contractors and sub-contractors) for indirect,
         incidental or consequential damages resulting from or arising out of
         this CONTRACT, including, without limitation, loss of profits, loss of
         production or business interruption howsoever same may be caused,
         including that caused by the sole, joint and/or concurrent negligence,
         fault or strict liability of OPERATOR GROUP. CONTRACTOR shall be
         responsible for ensuring that its subcontractors agree to release,
         defend, indemnify and hold harmless OPERATOR GROUP for such claims and
         damages.

8.8      Except as otherwise expressly provided for in the CONTRACT, whenever
         under any provision in Clauses 7.2, 7.3, 8, 9.5 or 23 of the CONTRACT
         it is provided that one of the Parties hereto shall be liable or
         responsible in respect of any loss or damage to property or injury to
         or death of personnel, or where it is provided that either Party shall
         indemnify the other Party against any liability, claim, demand, or

         other Party, its shareholders, its and their parent, holding and
         affiliated companies, directors, officers, employees and agents and
         CO-VENTURERS, from and against any and all claims and rights of action
         asserted directly or indirectly against any or all of the Parties to be
         so indemnified.

         Any indemnities expressed to be in favour of CONTRACTOR shall be deemed
         to extend also to the DRILLING UNIT and its legal owner (with respect
         to actions IN REM).

         It is the intent that where in this CONTRACT responsibility or
         liability is assumed by either of the Parties hereto or where either of
         the Parties agrees to indemnify the other Party in respect of any
         claim, demand or cause of action, unless it is otherwise expressly
         stated herein, such assumption of liability and/or indemnification
         shall apply notwithstanding the sole, passive, active or concurrent
         negligence of, or unseaworthiness of any vessel owned or under CONTRACT
         or chartered by, any Party hereto or of or by any person, firm or
         corporation for which such Party is responsible (whether or not such
         negligence or unseaworthiness related to a pre-existing condition or
         defect), breach of representation, warranty, duty (contractual,
         statutory or otherwise) or other theory of liability, including strict
         liability, which may be applicable.

         If any contractor of OPERATOR, (other than any vessel owner and/or
         operator), as part of its indemnity obligation to OPERATOR, agrees to
         release, defend, indemnify and hold harmless CONTRACTOR, then
         CONTRACTOR shall, to the same extent, agree to release, defend,
         indemnify and hold harmless said contractor (other than any vessel
         owner and/or operator) whereby the indemnity obligations of CONTRACTOR
         set forth in this clause 8 shall extend to said contractor.

         The CONTRACTOR releases and indemnifies the OPERATOR against any and
         all costs, claims, demands, proceedings, causes of action, losses or
         damage (including but not limited to THIRD PARTY claims or liability)
         arising out of the CONTRACT howsoever caused during the period from the
         EFFECTIVE DATE until the actual FIRST WELL COMMENCEMENT DATE.

         and/or in which persons may be killed or injured. The Parties desire to
         allocate these risks between them and to require that these risks be
         adequately insured so as to minimize the possibility of disputes and to
         engage in effective risk management. For these reasons, the Parties
         agree to the insurance requirements, mutual indemnities and defense
         obligations set forth in this CONTRACT.

9.2      The Parties agree that the indemnity and insurance obligations
         contained in this CONTRACT are separate and apart from each other, such
         that failure to fulfill the indemnity obligation does not alter or
         eliminate the insurance obligation or vice versa. The Parties further
         agree that the insurance obligations shall support but will not in any
         way limit the defense and indemnity obligations set forth herein.

9.3      CONTRACTOR shall maintain at its own expense such insurance necessary
         to protect against all claims for damages, risks of losses, and
         contractual indemnities expressly assumed by CONTRACTOR under this
         CONTRACT, specifically including without limitation any and all risks
         and/or claims assumed by CONTRACTOR set forth in Clause 8, and shall
         secure and maintain policies with the minimum limits and other
         requirements stated in Exhibit "3" attached to and incorporated into
         this CONTRACT. All such policies shall be issued by insurance companies
         satisfactory to OPERATOR, with an AM Best rating of B or higher or
         alternatively shall be issued by Underwriters at Lloyds of London or
         the Member Companies of the Institute of London Underwriters or other
         such underwriters of equally sound financial condition. All such
         policies (except workers' compensation coverage) shall with respect to
         the indemnity obligations expressly assumed by CONTRACTOR under this
         CONTRACT:

         (1)      name OPERATOR GROUP as additional insured, and

         (2)      be primary in relation to any policies in which any member of
                  OPERATOR GROUP is a named or additional insured.

         CONTRACTOR waives all rights of subrogation (whether by loan receipt,
         equitable assignment, or otherwise) against OPERATOR GROUP and any of
         their insurers. CONTRACTOR warrants that its insurers similarly waive
         any such rights of subrogation which CONTRACTOR's insurers may have
         against OPERATOR GROUP or its insurers.

         The Parties agree that CONTRACTOR is not required to obtain coverage
         protecting OPERATOR GROUP for those risks specifically allocated to
         OPERATOR in Clauses 7.2, 7.3, 8, 9.5 or 23 of this CONTRACT.

- --------------------------------------------------------------------------------


         Prior to performing the DRILLING SERVICES for OPERATOR, CONTRACTOR
         shall furnish OPERATOR certificates of insurance reflecting insurance
         coverage in accordance with the requirements of Exhibit "3". Failure of
         OPERATOR to object to CONTRACTOR's failure to furnish such certificates
         or to object to any defect in such certificates shall not be deemed a
         waiver of CONTRACTOR's obligation to furnish such a certificate and to
         provide insurance coverages as prescribed in Exhibit "3".

         In the event that CONTRACTOR fails to perform any of its obligations
         hereunder with respect to insurance, with or without the knowledge or
         consent of OPERATOR, then CONTRACTOR shall itself be an insurer to the
         extent it has failed to perform such obligations.

9.4      If the CONTRACTOR shall fail to effect and keep in force any of the
         insurances referred to herein, then the OPERATOR may effect and keep
         the same in force and pay such premium as may be necessary for that
         purpose and from time to time deduct the amount so paid by the OPERATOR
         as aforesaid from any monies due or which may become due to the
         CONTRACTOR or recover the same as a debt due from the CONTRACTOR.

9.5      In the event the OPERATOR takes over the CONTRACTOR's EQUIPMENT as
         provided in Clause 7.2 hereof, then the OPERATOR shall have the right
         at its cost and expense to take over the CONTRACTOR's insurance,
         provided that CONTRACTOR's underwriters approve continuation of such
         insurance and provided further that OPERATOR reimburses CONTRACTOR for
         any premium increases or surcharges imposed by CONTRACTOR's insurance
         underwriters in the event of a takeover.

         If CONTRACTOR'S underwriters do not approve the continuation of such
         insurance, OPERATOR shall assume all risks of loss, damage, injury or
         death which would have been covered by CONTRACTOR'S insurance had such
         insurances been in effect. In such event all of CONTRACTOR's
         indemnities, except for patent infringement, shall be inapplicable.

9.6      Nothing contained in this Article 9 shall be construed as restricting
         or prohibiting CONTRACTOR from arranging with its subcontractor,
         Caspian Drilling Company (CDC), for CDC to provide any or all of the
         insurance coverages contemplated to be provided by the CONTRACTOR under
         this CONTRACT, provided that such insurance coverages are at least
         equivalent to the insurance described in this Article 9.

                     CLAUSE 10 TAX INFORMATION AND INDEMNITY

10.1     It is understood and agreed that CONTRACTOR's rates and charges are
         inclusive of all Taxes imposed, directly or indirectly, on CONTRACTOR
         or its subcontractors, employees, agents or servants as a result of
         this CONTRACT. Upon prior notice to CONTRACTOR, OPERATOR shall deduct
         or withhold from any payment made by it under this CONTRACT any Taxes
         required to be so deducted or withheld under any applicable laws or
         regulations. OPERATOR shall use its best efforts to provide the notice
         required in the preceding sentence not less than ten (10) business days
         prior to such withholding. The Petroleum Operations carried out by
         CONTRACTOR and its subcontractors under this CONTRACT shall be subject
         to the tax provisions of the OPERATOR's PSA and its related protocols
         with respect to Taxes to the extent such provisions are applicable.
         OPERATOR shall not reimburse CONTRACTOR for any Taxes imposed, directly
         or indirectly, on CONTRACTOR or its subcontractors, employees, agents
         or servants as a result of this CONTRACT.

10.2     The CONTRACTOR shall pay any and all Taxes, and shall ensure the due
         payment by any of its subcontractors, employees, agents or servants of
         all Taxes, imposed, directly or indirectly, on the CONTRACTOR, or any
         of its subcontractors, employees, agents or servants as a result of
         this CONTRACT. CONTRACTOR shall be responsible for the reporting,
         filing and payment of any Taxes and any related fines, penalties or
         interest imposed directly or indirectly on CONTRACTOR GROUP as a result
         of CONTRACTOR's performance under this CONTRACT.

10.3     The CONTRACTOR shall release, defend, indemnify and hold harmless
         OPERATOR GROUP from and against any and all payments required to be
         made or liabilities, losses, costs or expenses of whatsoever nature
         incurred by the OPERATOR GROUP as a result of or in connection with any
         failure by the CONTRACTOR or any of its subcontractors, employees,
         agents or servants to comply with the provisions of Clause 10 hereof.

10.4     "Taxes" shall be defined as all levies, duties, payments, fees, taxes
         or contributions payable to or imposed by any governmental authority.

10.5     Except as provided in Exhibit 5, Clause 5.7, the Rates and Charges set
         forth in Exhibit "5" shall not be revised to reflect any changes in the
         Taxes imposed, directly or indirectly, on CONTRACTOR or its
         subcontractors, employees, agents or servants as a result of this
         CONTRACT.

                       CLAUSE 11 BANKRUPTCY OR LIQUIDATION


If the CONTRACTOR shall become bankrupt or insolvent, or have a receiving order
made against it, or present a petition in bankruptcy or make an arrangement with
or an assignment in favour of its creditors, or shall agree to carry out the
CONTRACT under a Committee of Inspection of its creditors, or commence to be
wound up (not being a member's voluntary winding up for the sake of
reconstruction), or shall carry on its business under a receiver for the benefit
of its creditors or any of them then the OPERATOR shall be at liberty either:

(a)      to suspend immediately all or any of the operations then in progress
         and apply the provisions of sub-clause 7.1 hereof, or

(b)      to give such receiver, liquidator or any other person in whom the
         CONTRACT may become vested the option of carrying out the CONTRACT
         subject to his providing a guarantee in an amount to be agreed for the
         due and faithful performance of the CONTRACT without prejudice in
         either event to any right of action or remedy which shall have accrued
         or shall accrue thereafter to the OPERATOR.

                             CLAUSE 12 FORCE MAJEURE

No failure or omission by either Party to carry out or observe any of the
stipulations, conditions or obligations to be performed hereunder shall, except
as herein expressly agreed to the contrary, give rise to any claim against such
Party or be deemed to be a breach of the CONTRACT if such failure or omission
arises from an event of FORCE MAJEURE.

In this CONTRACT, FORCE MAJEURE shall mean occurrences such as expropriation,
confiscation, orders of governmental authority, acts of war (declared or
undeclared), insurrection, rebellion, sabotage, civil disturbances, strikes
(except of the CONTRACTOR's or SUBCONTRACTOR's own workforce), actions of the
elements (except waiting on weather in the field) or other events beyond the
reasonable control of the Parties affected thereby but specifically excluding
financial distress and obligations to make payment by one Party to the other
under this CONTRACT.

If by any reason of FORCE MAJEURE either Party shall be prevented from executing
or continuing to execute the CONTRACT, the Party so prevented shall forthwith
give notice in writing to the other Party of such prevention and the reasons
therefor. The obligations of the Parties as have been thus affected shall be
suspended for the duration of such prevention.

In the event that the CONTRACTOR is unable to carry out the DRILLING SERVICES by
reason of FORCE MAJEURE the OPERATOR shall have the right to instruct the

appropriate rate as set out in Exhibit "5" shall be payable.

In the event the OPERATOR does not exercise the above right and the execution of
the CONTRACT has been prevented for not less than ninety (90) days then either
Party shall have the right to terminate the CONTRACT by giving written notice to
the other. Upon such notice being given, the CONTRACT shall forthwith be
terminated in respect of that operation or the whole of the CONTRACT according
to the subject matter of the notice, but without prejudice to the claim under
the CONTRACT of any Party in respect of any antecedent breach thereof. In the
event of such termination, CONTRACTOR shall be paid for all work performed up to
the effective date of termination together with the appropriate Early
Termination Fee and, if it is practical to demobilise the DRILLING UNIT, it
shall be demobilised in accordance with the provisions of this CONTRACT.

                          CLAUSE 13 FREEDOM FROM LIENS

Without prejudice to any other provision of the CONTRACT the CONTRACTOR shall
release, defend, indemnify and hold harmless OPERATOR from and against all
liens, attachments or claims by or on behalf of any of the CONTRACTOR's
suppliers, subcontractors, CONTRACTOR's PERSONNEL or SUBCONTRACTORs in
connection with or arising out of the CONTRACT. In such an instance, OPERATOR
shall have the right to withhold payment until CONTRACTOR has provided proof to
OPERATOR that all such liens have been released, provided that CONTRACTOR has
not posted a bond or other security satisfactory to OPERATOR within five (5)
days of OPERATOR's notice of such liens.

                 CLAUSE 14 CONTRACTOR TO MAINTAIN REPRESENTATION

For a period of not less than two (2) years after the termination or completion
of the CONTRACT howsoever arising the CONTRACTOR shall maintain representation
in Azerbaijan through the services of a person, firm or corporation resident in
the CONTRACT AREA. Such person, firm or corporation shall be empowered to act
and shall have the right to receive summonses on behalf of the CONTRACTOR in any
matter having reference to the business or affairs of the CONTRACTOR and arising
out of or connected with the CONTRACT. Before appointing any such person, firm
or corporation the CONTRACTOR shall obtain the prior approval of the OPERATOR
thereto.

Regulations or By-Law of any Local or other duly constituted authority having

be affected, provided always that the OPERATOR will, subject always to Clause 10
herein, repay or allow to the CONTRACTOR all such sums as OPERATOR's
REPRESENTATIVE shall certify to have been properly and necessarily payable and
paid by the CONTRACTOR in respect of any such fees or monies the obligation for
which does not exist at the date hereof, provided further that in respect of any
such fees or monies the obligation for payment of which does exist at the date
hereof but which ceases after the date hereof the CONTRACTOR shall repay or
allow to the OPERATOR all such sums as OPERATOR's REPRESENTATIVE shall certify
are not properly payable by it or which if paid are refundable to it.

                       CLAUSE 16 CONFIDENTIAL INFORMATION

All information obtained by the CONTRACTOR in the course or conduct of its
services hereunder shall be considered confidential and shall not be divulged by

regarding confidentiality shall not apply to any of the following:

(i)    information in the public domain or generally available to the public

(ii)   disclosure of information in the CONTRACTOR's possession prior to being
       furnished by or on behalf of OPERATOR;

(iii)  information received by CONTRACTOR from another source when such source
       is not restricted in its use or disclosure of such information;

(iv)   information required to be disclosed by operation of applicable law;

(v)    information describing the specification of the DRILLING UNIT given to a
       bona fide prospective customer of CONTRACTOR provided such disclosure

Permission should first be obtained from SOCAR prior to disclosing any
information under (v) above to third parties. The confidentiality obligations
under this clause shall survive for a period of five (5) years following
termination of the OPERATOR's PSA.

                               CLAUSE 17 PUBLICITY

The CONTRACTOR shall not publish or permit to be published either alone or in
conjunction with any other person any articles, photographs or other
illustrations relating to the work hereunder, or OPERATOR's business generally,
without prior reference to and approval in writing from OPERATOR. Such consent
shall only apply to each specific application and relate only to that
application. The accuracy of any information which was not supplied directly by
OPERATOR shall be the absolute responsibility of the CONTRACTOR. The obligations
of this clause shall continue notwithstanding the completion or termination of
the work under this CONTRACT.

                     CLAUSE 18 ASSIGNMENT AND SUBCONTRACTING

18.1     Assignment

         The CONTRACTOR shall not without the prior written consent of the
         OPERATOR assign the CONTRACT or any part thereof or any benefit or
         interest therein or thereunder to any party other than a wholly-owned
         subsidiary of the Santa Fe International Corporation. Such consent
         shall not be unreasonably withheld. If CONTRACTOR assigns the CONTRACT
         or any part thereof or any benefit or interest therein or thereunder to
         a wholly-owned subsidiary of Santa Fe International Corporation, then
         prior to such assignment CONTRACTOR shall provide to COMPANY a Parent
         Company Guarantee in the form of Exhibit 2 hereto.

         OPERATOR may assign or sub-let the whole or part of this CONTRACT, its
         rights, liabilities and obligations to an AFFILIATE of the BP Amoco plc
         and to Agip Azerbaijan BV or its AFFILIATE operating the Kurdashi PSA
         upon the same terms and conditions as those agreed between the parties
         hereto without consent of the CONTRACTOR, and to any other party with
         the prior written consent of the CONTRACTOR. Such consent shall not be
         unreasonably withheld.

         When this CONTRACT is assigned it shall be assigned on the terms and
         conditions of the Assignment Agreement in the form which is attached
         hereto as Exhibit "1".

         When the CONTRACT is assigned, the Rates and Charges set forth in
         Exhibit "5" of the CONTRACT shall be revised to reflect variations in
         CONTRACTOR's operating costs in carrying out the DRILLING SERVICES only
         if caused solely as a result of such assignment and only as
         specifically provided for herein. Except as otherwise provided for
         herein or elsewhere in this CONTRACT, cost variations in

C-2000-AIOC-21467                                                  PAGE 25 OF 33

- --------------------------------------------------------------------------------


         CONTRACTOR's operating costs in carrying out the DRILLING SERVICES will
         be subject to adjustment, if solely the result of the assignment of the
         CONTRACT, and shall be the following cost variations: (i) compliance
         with the assignee's safety, hygiene and import/export procedures, and
         (ii) compliance with the assignee's fire and safety regulations.
         Provided, further, that matters set forth elsewhere in the CONTRACT or
         its Exhibits which expressly call for CONTRACTOR to assume the
         obligation for compliance and/or expressly address adjustments of costs
         by and between the Parties (by way of example this includes but is not
         limited to Clause 10 herein and Section 5.7 of Exhibit "5" herein )
         shall not be subject to adjustment under this Clause 18. In all other
         cases, when the CONTRACT is assigned, the Rates and Charges set forth
         in Exhibit "5" of the CONTRACT shall be revised to reflect variations
         in CONTRACTOR's operating costs in carrying out the DRILLING SERVICES
         only if, solely as a result of such assignment, there is an increase or
         decrease in the operating requirements imposed on CONTRACTOR by the
         assignee that results in an increase or decrease of the CONTRACTOR's
         operating costs in a manner not originally contemplated by the Parties
         with respect to the work to be performed by CONTRACTOR under the
         CONTRACT. Such variations in cost shall be supported by auditable
         evidence of the actual cost changes properly documented and supported
         by CONTRACTOR to OPERATOR's reasonable satisfaction: provided further
         that with respect to cost increases no such cost variations shall be
         allowed unless the assignee is advised in advance of such changes and
         has been given the opportunity to modify its operating requirements to
         avoid the cost increase.

18.2     Subcontracting

         The CONTRACTOR shall not enter into any subcontract for the whole or
         any part of its obligations under the CONTRACT other than with Caspian
         Drilling Company Limited without the prior written consent of the
         OPERATOR and such consent if given shall not relieve the CONTRACTOR
         from any liability or obligation under the CONTRACT and the CONTRACTOR
         shall be responsible for the acts, breaches of contract, defaults and
         negligence of any SUBCONTRACTOR, its personnel or agents as fully as if
         they were the acts, defaults, breaches of contract or negligence of the
         CONTRACTOR, its personnel or agents.

         The CONTRACTOR shall ensure that all its subcontracts shall include
         provisions to the like effect as the provisions hereof. In addition the
         CONTRACTOR shall ensure that the SUBCONTRACTOR's personnel (where
         applicable) are made aware of, and follow the provisions for Fire and
         Safety Precautions and Emergency Procedures as set out in Exhibit 4.

- --------------------------------------------------------------------------------


18.3     Under no circumstances shall any subcontractor of CONTRACTOR or its
         agents, servants or employees be considered employees of OPERATOR.

18.4     If CONTRACTOR shall cause any part of the DRILLING SERVICES hereunder
         to be performed by a subcontractor, CONTRACTOR shall provide on behalf
         of such subcontractor or require such subcontractor to procure and
         maintain in effect for the duration of the subcontract such insurance
         coverages as are set forth elsewhere in this CONTRACT as applicable to
         such subcontractor which coverages shall, with respect to the risks
         expressly assumed by such subcontractor under its subcontract, name
         OPERATOR GROUP as additional insured, be primary, and contain the
         waiver of subrogation specified herein.

                  CLAUSE 19 APPLICATION OF LAWS AND REGULATIONS

The CONTRACTOR shall comply with all Laws, Rules and Regulations of Government
or local or other authority which are effective at the date hereof or may in the
future become applicable to the CONTRACTOR's business, CONTRACTOR's EQUIPMENT
and CONTRACTOR's PERSONNEL engaged in the operations hereunder. The CONTRACTOR
shall promptly advise the OPERATOR of any such laws, rules or regulations with
which it believes it is unable to comply.

The CONTRACTOR shall ensure that its PERSONNEL, SUBCONTRACTORs and agents
observe all such laws, rules and regulations and shall at the CONTRACTOR's
expense replace any CONTRACTOR's PERSONNEL or SUBCONTRACTOR's personnel or
agents whose conduct or behavior may reasonably be considered by the OPERATOR to

22.1     In the performance of the DRILLING SERVICES the CONTRACTOR shall be an
         independent contractor with the authority to control and direct the
         performance thereof. OPERATOR is interested only in the results
         obtained and shall not have the right to control or direct the details
         of the services performed by CONTRACTOR, but the DRILLING SERVICES
         shall be subject to the approval of the OPERATOR and be subject to a
         general right of inspection and any necessary supervision thereof

         times have access to all parts of the DRILLING UNIT for the purpose of
         inspecting the CONTRACTOR's EQUIPMENT or observing tests or inspecting
         the DRILLING SERVICES. In addition, operations shall be carried out at
         the request and in accordance with the instructions of the OPERATOR's
         REPRESENTATIVE who shall inform the CONTRACTOR's REPRESENTATIVE of the
         end result desired from any operation, but the CONTRACTOR shall have
         the entire responsibility for the proper and timely execution thereof.

22.3     The CONTRACTOR shall give all reasonable assistance to the OPERATOR's
         REPRESENTATIVE in the performance of his duties. However, the presence
         of and/or inspection and/or supervision by the OPERATOR's
         REPRESENTATIVE hereunder shall not relieve the CONTRACTOR of any of its
         obligations or responsibilities hereunder.

The CONTRACTOR shall release, defend, indemnify and hold harmless the OPERATOR

shall defend at its sole expense any and all such proceedings to which both
Parties are defendants, provided, however, that such indemnity shall not apply
and OPERATOR shall release, defend, indemnify and hold harmless CONTRACTOR
therefor if the equipment, machinery, materials or process which infringes on
the patent, design, trademark or name or other protected right was specified or
provided by OPERATOR. Both the CONTRACTOR and the OPERATOR shall at all times
have the right to be represented respectively by their own counsel and to
participate in the defense of any such proceedings if both shall be made Parties
defendant thereto. Each Party shall give notice in writing forthwith to the
other party of any such claims and proceedings as aforesaid and shall supply the
other party with all information and documents in connection therewith as the
other Party may reasonably require.

         25.4.5   the decision of a majority of the arbitrators shall be final

                  judicial acceptance of the award and an order of enforcement,
                  as the case may be; and

         25.4.7   each Party hereto, for the purposes of allowing such
                  arbitration and the enforcement and execution of any
                  arbitration decision, award, issuance of any attachment,
                  provisional remedy or other pre-award remedy, hereby waives

matters, trade secrets, formulas or processes from such inspection and audit.

or remedy that OPERATOR may have under this CONTRACT or at law.

         Company Limited) notwithstanding anything to the contrary in this
         CONTRACT.

28.3     Severance of Invalid Provisions

         If and for so long as any provision of this CONTRACT shall be deemed to
         be judged invalid for any reason whatsoever, such invalidity shall not

         CONTRACT and any such invalid provision shall be deemed severed from

28.7     Conflicts of Interest

         CONTRACTOR undertakes that it shall not use any information received as
         a result of its status as a Party under the CONTRACT to gain an
         advantage for other operations which it may be or it anticipates it may
         be conducting or participating in, to the material disadvantage of the
         operations contemplated under this CONTRACT.

                  beyond 15 March 2000 for reasons beyond the control of the

                           date") for or due to:

                    (a)    Increases or decreases in the salaries, wages

         5.7.2    At one year intervals, with the first revision being due 1
                  January 2001, the Rates and Charges set forth herein shall be
                  revised to reflect variations in CONTRACTOR's costs after 1
                  January 2000 (the "Base Date") for or due to:

                    (a)    Decreases or unavoidable increases in CONTRACTOR's
                           insurance and catering costs. Base Cost for insurance

                           actual cost changes properly documented and supported
                           by CONTRACTOR to OPERATOR's reasonable satisfaction.

                           shall be calculated in accordance with increases or
                           decreases reported in the Bureau of Labour Statistics

                           Department of Labour after the Base Date. Each
                           revision shall be determined by multiplying the
                           percentage change between the then current Index and
                           that which was in effect on the Base Date times the
                           Base Cost.

         5.7.3    Rates and Charges herein set forth shall be adjusted when the
                  combined amount of the revision is greater than United States
                  Dollars Two Hundred and Fifty per day (U.S. $250/day) on 1

         5.7.4    CONTRACTOR shall maintain a complete and correct set of
                  records pertaining to all aspects of the matters set forth in
                  this Section 5.7. OPERATOR shall have the right to audit any
                  and all relevant records relating to the increases or
                  decreases in the Rates and Charges as provided for in this
                  Section 5.7 within a period of twenty-four (24) months after
                  the settlement of the final invoice for DRILLING SERVICES
                  hereunder provided that CONTRACTOR shall have the right to
                  exclude any proprietary matters, trade secrets, formulas or
                  processes from such inspection and audit. Should the results
                  reveal that payments have been made incorrectly, appropriate
                  adjustments shall be made. Neither the completion of such
                  audit by OPERATOR nor the decision not to conduct an audit
                  shall waive, forfeit or prejudice any

                  or enforcement thereof, which becomes effective after the Base

                  YEAR OF THE CONTRACT SHALL BE CONSIDERED TO COMMENCE ON THE
                  SECOND WELL COMMENCEMENT DATE.

                  The applicable Early Termination Fee shall be calculated by
                  considering the actual date of termination against the
                  following fixed reference points.

                  a)       If the Contract is terminated at any time during the
                           first year of the CONTRACT:

                           -        U.S. $23,100,000 plus the non-GCA-6 WELL

                                    Days.

                  b)       If the CONTRACT is terminated at any time during the
                           second year of CONTRACT:

                           -        U.S. $19,400,000 plus U.S. $10,137 for each
                                    Day the actual duration of the CONTRACT is
                                    less than 730 Days.

                  c)       If the CONTRACT is terminated at any time during the

                                    less than 1,095 Days.

                  d)       If the CONTRACT is terminated at any time during the
                           fourth year of the CONTRACT:

                           -        U.S. $9,500,000 plus U.S. $14,795 for each
                                    Day the actual duration of the CONTRACT is
                                    less than 1,460 Days.

                  e)       If the Contract is terminated at any time after the
                           1,460th Day of the CONTRACT:

                           -        U.S. $17,336 for each Day the actual
                                    duration of the CONTRACT is less than 2,008
                                    Days.

                  The above-applicable Early Termination Fee excludes any
                  element of withholding Tax payment. If CONTRACTOR is subject
                  to Azerbaijan withholding Tax on such Early Termination Fee,
                  then the applicable Fee shall be adjusted as necessary to
                  include the applicable withholding tax in order that the net
                  Early Termination Fee to be received by CONTRACTOR after such
                  tax has been withheld remains as stated above.
