              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)


1.   CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

     The condensed consolidated financial statements included in this report are
unaudited but in the opinion of management include all adjustments, consisting
only of normal recurring adjustments, necessary for a fair presentation of the
financial information for the periods indicated. All dollar amounts in the
tabulations in the notes to the financial statements are stated in thousands
unless otherwise indicated. Certain reclassifications have been made in the 1998
financial statements to conform with the 1999 presentation. Certain information
and footnote disclosures normally included in financial statements prepared in
accordance with generally accepted accounting principles have been condensed or
omitted.

2.   MERGER AGREEMENT

     On January 10, 1999, the Company entered into a definitive agreement and
plan of merger (the "Merger Agreement") among the Company, Nabors Industries,
Inc. ("Nabors") and Starry Acquisition Corp., a wholly owned subsidiary of
Nabors ("Merger Sub"). The Merger Agreement provides, subject to certain
conditions set forth therein, that Merger Sub will be merged (the "Merger") with
and into the Company, with the Company continuing as the surviving corporation
and a wholly owned subsidiary of Nabors. At the effective time of the Merger,
each share of common stock, without par value, of the Company (the "Pool Common
Stock") issued and outstanding (excluding any treasury shares held by the
Company and shares held by Nabors or any of its subsidiaries), including the
associated common stock purchase rights, if any, outstanding at the effective
time of the Merger, will be converted into the right to receive 1.025 shares of
common stock, par value $.10 per share, of Nabors (the "Nabors Common Stock").
The Merger Agreement provides for certain conditions to the closing of the
Merger, including, among other things, the approval of the holders of at least
two-thirds of the Pool Common Stock, the registration with the Securities and
Exchange Commission of the shares of Nabors Common Stock to be issued in
connection with the Merger, the expiration or termination of the applicable
waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976,
as amended (the "HSR Act") and the reaching of an agreement with the Company's
Saudi Arabian joint venture partner with respect to the post-merger operations
of the Company's Saudi Arabian joint venture and Nabors' existing Saudi Arabian
business (the "Saudi Agreement"). The applicable waiting period under the HSR
Act has expired, the registration statement with respect to the Nabors shares
became effective on August 9, 1999 and the Merger was approved by the holders of
more than the requisite two-thirds of the Pool Common Stock on September 28,
1999. Final agreement has not been reached with regard to the Saudi Agreement,
but the Company expects this condition to be satisfied. Although the Merger
Agreement provides that it can be terminated by either party if closing of the
Merger did not occur by October 1, 1999, both parties are continuing to use
their best efforts to effect satisfaction of the conditions and close as
promptly as practicable. However, there can be no assurances as to whether or
when the transaction will be completed.

     The 1999 EPS calculations exclude options to purchase approximately
1,412,000 shares of common stock that were outstanding during the third quarter
of 1999 because the inclusion of such options would have been antidilutive due
to the net loss during the period.

     The 1998 EPS calculations exclude options to purchase approximately 926,000
shares of common stock at exercise prices ranging from $10.00 per share to
$35.50 per share because the inclusion of such options would have been
antidilutive.

5.   LONG-TERM DEBT AND CREDIT AGREEMENT

     SENIOR SUBORDINATED NOTES

     In March 1998, the Company issued 8 5/8% Senior Subordinated Notes due 2008
(the "Notes") in the aggregate principal amount of $150 million and used the net
proceeds from the sale thereof to fund the cash portion of the Sea Mar, Inc.
("Sea Mar") purchase, to repay the existing debt of Sea Mar and to reduce the
outstanding balance under the Company's Credit Agreement.

     The Notes are general unsecured obligations of the Company subordinated in
right of payment to all existing and future senior indebtedness of the Company
and are unconditionally guaranteed, jointly and severally, by each of the
Company's wholly-owned subsidiaries that are incorporated or organized in the
United States (the "Subsidiary Guarantors"). The other subsidiaries of the
Company are not guarantors of the Notes (the "Non-Guarantor Subsidiaries"). The
Notes contain certain covenants that, among other things, limit the ability of
the Company and the Subsidiary Guarantors to incur additional indebtedness,
issue capital stock of Subsidiary Guarantors, pay dividends or make other
restricted payments, incur liens, enter into certain transactions with
affiliates, enter into certain mergers or consolidations or sell all or
substantially all of the assets of the Company and its subsidiaries.

     CREDIT AGREEMENT

     In March 1998, simultaneously with the issuance of the Notes and the
acquisition of Sea Mar, the Company executed an amendment to its three-year
$130 million three-year syndicated bank credit agreement (the "Credit
Agreement") to provide for maximum borrowings of up to $180 million, of which
amount up to $25 million may be used to support letters of credit. At September
30, 1999, the Company had drawn $45.0 million in cash under the Credit
Agreement, and an additional $6.6 million was being utilized to support the
issuance of letters of credit, primarily related to insurance obligations and
long-term notes issued in connection with the 1995 acquisition of Golden
Pacific Corp.

Borrowings under the Credit Agreement bear interest, at the Company's option, at
either (i) the Base Rate (defined as the higher of the administrative agent
bank's prime lending rate or 1/2 of 1% in excess of the federal funds rate) plus
a margin ranging from zero to .50%, or (ii) the Eurodollar Rate (equivalent to
the London Interbank Offered Rate plus a margin ranging from 1% to l.75% with
the Company's option of a one-, two-, three- or six-month interest period). The
applicable margin for each interest option depends on the Company's leverage
ratio for the fiscal quarter preceding the interest period. Based upon the
Company's leverage ratio at September 30, 1999, the applicable Eurodollar margin
will be 1.75% for borrowings during the fourth quarter of 1999. The Credit
Agreement will mature on October 2, 2000 and is subject to being extended on a
year-to-year basis at the discretion of the lenders. Revolving loans issued
under the Credit Agreement are prepayable at any time and are due at expiration
on October 2, 2000. The Credit Agreement imposes certain financial covenants,
including ones requiring the maintenance of a minimum net worth, a minimum
interest coverage ratio, a minimum fixed charge coverage ratio, a maximum
leverage ratio and a maximum debt-to-equity ratio. It also imposes certain other
restrictions, including ones related to liens, other indebtedness, asset sales,
investments, acquisitions or mergers and the payment of dividends. The lenders
under the Credit Agreement have agreed to waive compliance with the maximum
leverage ratio provided for in the Credit Agreement for the quarter ended
September 30, 1999. The Credit Agreement is guaranteed on an unsecured basis by
substantially all of the Company's domestic subsidiaries. Advances under the
Credit Agreement are secured by a pledge of 66% of the capital stock of certain
of the Company's foreign subsidiaries.

(a)  On March 31, 1998, the Company acquired all of the outstanding capital
     stock of Sea Mar, Inc. ("Sea Mar"), a privately-owned Louisiana-based
     offshore support vessel company with operations primarily in the Gulf of
     Mexico.


7.   ACCOUNTING STANDARDS

     In June 1998, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 133, "Accounting for
Derivative Instruments and Hedging Activities". This statement establishes
accounting and reporting standards for derivative instruments and for hedging
activities. In June 1999, the FASB issued SFAS 137, "Accounting for Derivative
Instruments and Hedging Activities - Deferral of the Effective Date of FASB
Statement No. 133" which will delay the effective date of SFAS 133 to fiscal
years beginning after June 15, 2000. The Company is still in the process of
evaluating what effect, if any, SFAS 133 will have on the Company's financial
statements. The Company will adopt this statement no later than January 1, 2001.


8.   CONSOLIDATING FINANCIAL STATEMENTS

     Presented below is condensed consolidating financial information for Pool
Energy Services Co. (on a stand-alone basis) ("PESCO"), the Subsidiary
Guarantors (on a combined basis), and the Non-Guarantor Subsidiaries (on a
combined basis). Separate financial information of each Subsidiary Guarantor is
not presented because the Company has concluded that such financial information
is not material to the investors.

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

MERGER AGREEMENT

     The Merger Agreement entered into on January 10, 1999 among the Company,
Nabors and Merger Sub provides, subject to certain conditions set forth therein,
that Merger Sub will be merged with and into the Company, with the Company
continuing as the surviving corporation and a wholly owned subsidiary of Nabors.
At the effective time of the Merger, each share of Pool Common Stock issued and
outstanding (excluding any treasury shares held by the Company and shares held
by Nabors or any of it subsidiaries), including the associated common stock
purchase rights, if any, outstanding at the effective time of the Merger, is to
be converted into the right to receive 1.025 shares of Nabors Common Stock. The
Merger Agreement provides for certain conditions to the closing of the Merger,
including, among other things, the approval of the holders of at least
two-thirds of the Pool Common Stock, the registration with the Securities and
Exchange Commission of the shares of Nabors Common Stock to be issued in
connection with the Merger, the expiration or termination of the applicable
waiting period under the HSR Act and the reaching of an agreement with the
Company's Saudi Arabian joint venture partner with respect to the post-merger
operations of the Company's Saudi Arabian joint venture and Nabors' existing
Saudi Arabian business. The applicable waiting period under the HSR Act has
expired, the registration statement with respect to the Nabors shares became
effective on August 9, 1999 and the Merger was approved by the holders of more
than the requisite two-thirds of the Pool Common Stock on September 28, 1999.
Final agreement has not yet been reached with regard to the Saudi Agreement, but
the Company expects this condition to be satisfied. Although the Merger
Agreement provides that it can be terminated by either party if closing of the
Merger did not occur by October 1, 1999, both parties are continuing to use
their best efforts to effect satisfaction of the conditions and close as
promptly as practicable. However, there can be no assurances as to whether or
when the transaction will be completed.

SEA MAR ACQUISITION

     The Company's acquisition on March 31, 1998 of all of the outstanding
capital stock of Sea Mar, a privately owned Louisiana-based offshore support
vessel company with operations primarily in the Gulf of Mexico, involved
purchase consideration at closing of approximately $76.0 million in cash and
1,538,462 shares of the Company's common stock. During the first quarter of
1999, the Company paid additional cash consideration of approximately $2.9
million as a result of Sea Mar's financial performance for the fiscal year ended
December 31, 1998. The Company is also obligated to pay additional cash
consideration contingent upon Sea Mar's financial performance for the fiscal
year ending December 31, 1999, up to a maximum of $10 million, although the
latest projection of Sea Mar's 1999 financial performance indicates that no
additional payment should be due.

     As a result of the acquisition of Sea Mar, the Company operates a
diversified fleet of offshore support vessels in the Gulf of Mexico. At the time
of its acquisition, Sea Mar had a contract with a marine shipbuilder for the
construction of ten offshore support vessels at an estimated aggregate cost of
$78.5 million, net of deposits. Four of these new vessels were delivered during
the first nine months of 1999. The remaining six vessels are scheduled to be
delivered between the last quarter of 1999 and late 2000. The Company
anticipates that the expenditures for these vessels will be financed by
internally generated funds and other financing arrangements as needed.

RESULTS OF OPERATIONS - QUARTERS ENDED SEPTEMBER 30, 1999 AND 1998

     The Company incurred a net loss of $2.4 million in the third quarter of
1999, including after tax Merger-related expenses of $0.8 million, compared to
net income of $5.4 million generated in the third quarter of 1998. The average
crude oil price for the third quarter of 1999 was approximately 53% higher than
in the third quarter of 1998 and the average domestic natural gas price was 29%
higher comparing the same periods. Results from each of the Company's operating
segments for the third quarter 1999 were unfavorable to reported results for the
same period in 1998 despite the higher product prices, except in Alaska where
third quarter earnings in 1999 approximated third quarter earnings in 1998.
Overall, the Company's utilization and rates were down for the period due to the
lingering effect on the demand for the Company's services resulting from
depressed oil prices in 1998 and early 1999.

     Revenues. Revenues were $82.5 million in the third quarter of 1999, a 28%
decrease from revenues of $115.2 million in the third quarter of 1998. Each of
the Company's operating segments contributed to the $32.7 million decline.

     Domestic onshore well-servicing and production services revenues declined
$10.1 million or 17% in the third quarter of 1999 from the corresponding quarter
of 1998. Domestic onshore rig utilization dropped from 44% in 1998 to 39% in
1999 and rig hours declined approximately 39,000, from 268,000 in the third
quarter of 1998 to 229,000 in 1999. Rig rates also decreased by about 1% period
over period. The Company's truck and frac tank activity levels each declined by
approximately 23%. In the Gulf of Mexico, revenue of $11.4 million for the third
quarter of 1999 was 33% lower than that in the comparable period of 1998 with
rig utilization of 39% in 1999 compared to 55% in 1998. Average rates for the
offshore rigs in the third quarter of 1999 were 10% below the rates in the
comparable 1998 period. The Company's offshore support vessel operation, Sea
Mar, had revenue of $5.4 million during the third quarter of 1999 compared to
$13.9 million during third quarter of 1998. Vessel utilization was approximately
49% and 85% for the respective periods. Average day rates for the vessels
dropped approximately 42% comparing quarter to quarter.

     Internationally, revenues were down from $16.4 million for the quarter
ended 1998 to $8.7 million for the same period in 1999. Rig utilization in the
third quarter of 1999 was 42% compared to 55% in the third quarter of 1998.
Lower revenues resulted from reduced mobilization revenue generated by the
platform workover rig operating offshore Australia, completion of the contract
for the platform drilling rig offshore Australia and decreased utilization in
most of the Company's other international operating locations except in Pakistan
where the three rigs in country were fully utilized during the third quarter of
1999. In Alaska, quarterly revenue of $5.8 million in 1999 represented a 13%
decline from revenue of the comparable period in 1998. The decline resulted
primarily from lower rig utilization, 33% in 1999 compared to 50% in 1998, as
well as from reduced revenues from labor contracts.

     Earnings Attributable to Unconsolidated Affiliates. Earnings attributable
to unconsolidated affiliates were $2.0 million in the third quarter of 1999
compared to earnings of $1.6 million in the third quarter of 1998. The $0.4
million improvement in 1999 resulted from a $0.1 million increase by Pool
Arabia, Ltd. ("Pool Arabia"), a $0.2 million improvement by Pool International
Argentina S.A. ("PIASA") and a $0.1 million increase by the Company's joint
venture in Oman. The increase in earnings from Pool Arabia was due primarily to
higher income earned from Pool Arabia's operation of two rigs leased from the
Company. The loss attributable to the Company's 51% share of PIASA was less in
the third quarter of 1999 than in the comparable period of 1998 due to the
implementation of a cost reduction program in Argentina.

     Costs and Expenses. The Company's costs and expenses were $84.4 million in
the third quarter of 1999, a 19% reduction compared to costs and expenses of
$103.5 million in the corresponding quarter of 1998. Generally, costs and
expenses declined due to the company-wide drop in equipment utilization
experienced in 1999, however, the third quarter of 1999 included approximately
$1.3 million of Merger-related expenses. Depreciation expense increased in 1999
primarily due to the additional offshore support vessels delivered this year as
well as the 1998 rig upgrade in Alaska.

     Other Income - Net. Other income - net was $0.9 million in the third
quarter of 1999 and includes a $0.4 million gain from an insurance recovery
related to the loss of a ball mill in Alaska.




                                       20
<PAGE>   21
     Interest Expense. Interest expense in the third quarter of 1999 was $4.6
million, $0.3 million higher than in the corresponding period of 1998, primarily
due to higher borrowings under the Company's Credit Agreement during the 1999
period.

     Income Taxes. The Company recorded an income tax credit of $1.3 million on
a loss before income taxes of $3.7 million in the third quarter of 1999,
compared to income tax expense of $4.2 million on income before income taxes of
$9.5 million in the third quarter of 1998. The decrease in income tax expense in
the third quarter of 1999, compared to the third quarter of 1998, was primarily
due to lower pre-tax income in the third quarter of 1999, as a result of the
factors described above. The Company's interim period tax expense is determined
by utilizing the aggregate of estimated annual effective tax rates for each of
the Company's domestic and foreign tax jurisdictions.

RESULTS OF OPERATIONS - NINE MONTHS ENDED SEPTEMBER 30, 1999 AND 1998

     The Company incurred a net loss of $3.7 million in the first nine months of
1999, including after tax Merger-related expenses of $1.9 million, compared with
net income of $20.4 million generated during the first nine months of 1998.
Except for International and Alaska operations, results from each of the
Company's operating segments for the nine month period in 1999 were unfavorable
to reported results for the same period in 1998. Results from international
operations were improved primarily due to higher earnings attributable to Pool
Arabia and from Alaska operations due to the receipt of a payment related to the
early termination of a drilling contract. Overall the Company's utilization and
rates were down due to the effect on the demand for the Company's services
resulting from depressed oil prices which bottomed out in the last quarter of
1998 and, although steadily rising throughout the first nine months of 1999,
have negatively impacted the Company's earnings for the period.

     Revenues. Revenues were $236.6 million in the first nine months of 1999, a
34% decrease compared to revenues of $360.9 million in the first nine months of
1998. Each of the Company's operating segments contributed to the $124.3 million
decline.

     Domestic onshore well-servicing and production services revenues decreased
$61.0 million or 30% in the first nine months of 1999 from the corresponding
period of 1998 due to the lingering negative effect of low oil and gas prices.
Domestic onshore rig utilization was 37% in the first nine months of 1999,
compared to 49% in the first nine months of 1998. Domestic onshore rig hours
decreased from approximately 896,000 in 1998 to 648,000 in 1999 although rates
remained relatively flat. Utilization of the Company's trucks and frac tanks
also declined by approximately 27% and 52%, respectively. Gulf of Mexico
workover and drilling revenues decreased from $59.9 million in 1998 to $26.5
million in 1999. Rig utilization for the offshore rig fleet declined from 63% in
the first nine months of 1998 to 35% in the comparable period of 1999, while
average day rates decreased 25% comparing the same periods. Sea Mar, acquired on
March 31, 1998, had revenues of $15.9 million for the first nine months of 1999
versus $27.7 million for the period from acquisition to September 30, 1998.

     International operations revenues decreased to $29.6 million for the first
nine months of 1999 compared to $45.0 million in the 1998 period. The $15.4
million revenue decline was attributable to a reduction in utilization of rigs
in Ecuador, Guatemala, Oman, and Pakistan, reduced mobilization revenue
generated by the platform workover rig operating offshore Australia and the
completion of the contract for the platform drilling rig offshore Australia. In
Alaska, revenue of $23.0 million for the first nine months of 1999 represented a
$2.6 million reduction from revenues earned in the 1998 period. Revenues in
Alaska declined due to lower utilization of its rigs and fewer revenues from
labor contracts, but these decreases were partially offset by revenue received
during the first quarter of 1999 related to the early termination of a drilling
contract.

     Earnings Attributable to Unconsolidated Affiliates. Earnings attributable
to unconsolidated affiliates were $7.0 million in the first nine months of 1999,
compared to $2.8 million in the first nine months of 1998. Earnings attributable
to Pool Arabia increased $3.5 million from the first nine months of 1998 to $7.7
million in the first nine months of 1999, primarily due to income earned from
Pool Arabia's operation of two rigs leased from the Company and the reversal of
$2.2 million of excess deferred foreign income tax reserves related to the 1996
tax year, which has now been audited by the relevant foreign tax authorities.
The loss attributable to PIASA was $0.7 million less in the first nine months of
1999 than in the comparable period of 1998 due to the implementation of a cost
reduction program in Argentina.



                                       21
<PAGE>   22

     Costs and Expenses. The Company's costs and expenses were $244.2 million in
the first nine months of 1999, a 24% decrease compared to costs and expenses of
$319.7 million in the corresponding period of 1998. Generally, costs and
expenses declined due to the Company-wide drop in equipment utilization
experienced in 1999. However, the decline in 1999 was partially offset by
approximately $2.9 million of Merger-related expenses and the inclusion of a
full nine months of Sea Mar expenses compared to the 1998 period that included
only six months of Sea Mar costs.

     Other Income - Net. Other income - net was $5.9 million during the first
nine months of 1999 chiefly due to a $4.0 million settlement related to the 1997
loss of a rig in the Gulf of Mexico and a $0.4 million gain from an insurance
recovery related to the loss of a ball mill in Alaska.

     Interest Expense. Interest expense for the first nine months of 1999 was
$13.4 million. The $3.0 million increase over the comparable period of 1998
primarily resulted from interest expense related to the $150 million Notes
issued in March 1998 but was also due to higher borrowings under the Company's
Credit Agreement in the 1999 period.

     Income Taxes. The Company recorded an income tax credit of $4.3 million in
1999 on a loss before income taxes of $8.0 million in the first nine months of
1999, compared to income tax expense of $14.3 million on income before income
taxes of $34.7 million in the first nine months of 1998. The decrease in income
tax expense in the first nine months of 1999, compared to the first nine months
of 1998, was primarily due to lower pre-tax income in the first nine months of
1999, as a result of the factors described above, and the $1.3 million reversal
of overaccrued deferred foreign income tax liabilities. The Company's interim
period tax expense is determined by utilizing the aggregate of estimated annual
effective tax rates for each of the Company's domestic and foreign tax
jurisdictions.

FINANCIAL CONDITION AND LIQUIDITY

     Cash Flows. The Company had cash and cash equivalents of $17.9 million at
September 30, 1999 compared to $33.3 million at December 31, 1998. Working
capital was $60.0 million and $50.2 million at September 30, 1999 and December
31, 1998, respectively. The Company used a net $56.6 million for investing
activities in the first nine months of 1999, primarily for capital expenditures
of $54.5 million, including $32.5 million for the balance of the purchase of
four newly-constructed offshore support vessels, as well as $2.9 million of
additional cash consideration paid as a result of Sea Mar's financial
performance for the fiscal year ended December 31, 1998. The Company used a net
$136.3 million for investing activities in the first nine months of 1998,
primarily for capital expenditures of $70.7 million and $65.2 million, net of
cash acquired, for the purchase of Sea Mar.

     $150 Million Senior Subordinated Notes. In March 1998, the Company issued
8 5/8% Notes in the aggregate principal amount of $150 million and used the net
proceeds from the sale thereof to fund the cash portion of the Sea Mar purchase,
to repay the existing debt of Sea Mar and to reduce the outstanding balance
under the Company's Credit Agreement.

     The Notes are general unsecured obligations of the Company subordinated in
right of payment to all existing and future senior indebtedness of the Company
and are unconditionally guaranteed, jointly and severally, by each of the
Subsidiary Guarantors. The Notes contain certain covenants that, among other
things, limit the ability of the Company and the Subsidiary Guarantors to incur
additional indebtedness, issue capital stock of Subsidiary Guarantors, pay
dividends or make other restricted payments, incur liens, enter into certain
transactions with affiliates, enter into certain mergers or consolidations or
sell all or substantially all of the assets of the Company and its subsidiaries.

     $180 Million Credit Agreement. In March 1998, simultaneously with the
issuance of the Notes and the acquisition of Sea Mar, the Company executed an
amendment to its three-year $130 million Credit Agreement to provide for maximum
borrowings of up to $180 million, of which amount up to $25 million may be used
to support letters of credit. At September 30, 1999, the Company had drawn $45.0
million in cash under the Credit Agreement, and an additional $6.6 million was
being utilized to support the issuance of letters of credit, primarily related
to insurance obligations and long-term notes issued in connection with the 1995
acquisition of Golden Pacific Corp.


                                       22

 Borrowings under the Credit Agreement bear interest, at the Company's option,
at either (i) the Base Rate (defined as the higher of the administrative agent
bank's prime lending rate or 1/2 of 1% in excess of the federal funds rate) plus
a margin ranging from zero to .50%, or (ii) the Eurodollar Rate (equivalent to
the London Interbank Offered Rate plus a margin ranging from 1% to 1.75% with
the Company's option of a one-, two-, three-or six-month interest period). The
applicable margin for each interest option depends on the Company's leverage
ratio for the fiscal quarter preceding the interest period. Based upon the
Company's leverage ratio at September 30, 1999, the applicable Eurodollar margin
will be 1.75% for borrowings during the fourth quarter of 1999. The Credit
Agreement will mature on October 2, 2000 and is subject to being extended on a
year-to-year basis at the discretion of the lenders. Revolving loans issued
under the Credit Agreement are prepayable at any time and are due at expiration
on October 2, 2000. The Credit Agreement imposes certain financial covenants,
including ones requiring the maintenance of a minimum net worth, a minimum
interest coverage ratio, a minimum fixed charge coverage ratio, a maximum
leverage ratio and a maximum debt-to-equity ratio. It also imposes certain other
restrictions, including ones related to liens, other indebtedness, asset sales,
investments, acquisitions or mergers and the payment of dividends. The lenders
under the Credit Agreement have agreed to waive compliance with the maximum
leverage ratio provided for in the Credit Agreement for the quarter ended
September 30, 1999. The Credit Agreement is guaranteed on an unsecured basis by
substantially all of the Company's domestic subsidiaries. Advances under the
Credit Agreement are secured by a pledge of 66% of the capital stock of certain
of the Company's foreign subsidiaries. During the first nine months of 1999, the
Company drew $50.0 million in cash and made payments of $15.0 million to reduce
borrowings under the Credit Agreement and made a $0.6 million scheduled
principal payment on long-term debt. During the first nine months of 1998, the
Company made payments of $90.8 million to reduce borrowings under the Credit
Agreement, repaid Sea Mar's existing debt of $15.7 million and made $1.1 million
of scheduled principal payments on long-term debt.

     Sale and Leaseback. In December 1998, the Company entered into sale and
leaseback agreements with a leasing company with respect to two offshore jackup
rigs. These rigs had been leased by the Company for the previous five years and
were purchased by the Company for $2.3 million in December 1998 through the
exercise of a purchase option. The rigs were sold to the new leasing company for
$20.0 million in cash. The current leases for the two rigs provide for an
aggregate annual lease rate of approximately $2.7 million through December 2004.

     Capital Expenditures. The Company anticipates that 1999 capital
expenditures will consist of (i) approximately $12 million for maintenance of
its existing rig and offshore support vessel fleet, (ii) approximately $6
million to complete construction of a new Arctic drilling rig, Rig 9, in Alaska
and (iii) approximately $41 million for the payment of the balance of the
purchase price of five newly constructed offshore support vessels for the Sea
Mar operation. The Company anticipates that these expenditures will be financed
by internally generated funds, borrowings under the Credit Agreement and other
financing arrangements as needed. Except for the foregoing, the Company's
capital spending generally has been suspended pending consummation of the
Merger.


OTHER MATTERS

     Market Outlook. Historically, the demand for the Company's services has had
a strong correlation with the fluctuations in oil and natural gas prices.
Falling oil and gas prices, which began in late 1997 and bottomed out in
December 1998, have negatively affected the activity levels and financial
results of the Company, particularly since mid-1998. With the 1999 upward trend
of oil and gas prices, the Company is optimistic about a recovery of the demand
for its services and improvements in its rates, especially as we enter the year
2000. The Company remains confident that market conditions will improve over the
long term as demand and supply become more in balance and is optimistic about
its long-term outlook.

     Accounting Standards. In June 1998, the FASB issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities". This statement
establishes accounting and reporting standards for derivative instruments and
for hedging activities. In June 1999, the FASB issued SFAS 137, "Accounting for
Derivative Investments and Hedging Activities - Deferral of the Effective Date
of FASB Statement No. 133" which will delay the effective date of SFAS 133 to
fiscal years beginning after June 15, 2000. The Company is still in the process
of evaluating what effect, if any, SFAS 133 will have on the Company's financial
statements. The Company will adopt this statement no later than January 1, 2001.



                                       23
<PAGE>   24



     Impact of the Year 2000 Issue. Some of the Company's older computer
programs were written using a two digit year. As a result, those computer
programs may be unable to process date-sensitive information beyond the year
2000. This situation, which is not uncommon, is frequently referred to as the
Year 2000 or Y2K issue and can cause a temporary disruption of the ordinary
course of business. The Company has developed a plan to address its exposure to
the impact of the Y2K issue. An assessment of the critical financial and
operational systems has been made and the remediation of these systems is
approximately 95% complete. The testing phase of the critical systems is 90%
complete, and these systems are expected to be Year 2000 compliant by November
30, 1999. The inventory, assessment, modification and testing of the smaller
less critical financial and operational systems, many located internationally,
have been substantially completed. The assessment of systems embedded in the
Company's buildings, equipment and other infrastructures has been completed. To
date, there has been no discovery of a significant non-compliant embedded
system. As of September 30, 1999, the Company has spent approximately $0.5
million, exclusive of internal costs, on its Y2K initiatives, primarily for
incremental software purchases and outside consulting. The Company does not
separately track internal Y2K costs, which are largely salaries and benefits of
Company personnel working on the project. The Company expects the incremental
cost of full implementation of its Year 2000 plan to be approximately $0.6
million, exclusive of internal costs.

     The Company has formally communicated with the suppliers, customers and
financial institutions that it considers to be material third parties and is
evaluating its risks related to any possible failure of such third parties to be
Year 2000 compliant. The effect, if any, on the Company's results of operations
arising from the failure of these third parties to be Year 2000 compliant is not
reasonably estimable at this time. Risk assessment and contingency plans related
to these parties are expected to be complete by November 30, 1999.

     Development of contingency plans to protect the Company from Year
2000-related interruptions are in process and are expected to be complete by
November 30, 1999.

     The dates on which the Company plans to become Year 2000 compliant and the
costs associated with the related modifications are based on management's best
estimates, which were derived utilizing numerous assumptions regarding future
events, including the continued availability of certain resources, third party
modification plans and other factors. There can be no assurance that these time
or cost estimates will be achieved, and the actual results could be materially
different. Although the Company expects to be Year 2000 compliant by November
30, 1999 and believes that in a "most reasonably likely worst case scenario" it
will not be materially impacted by any third party non-compliance, failure by
the Company or by material third parties to fully implement appropriate Year
2000 plans could have a material adverse effect on the Company's results of
operations. Adverse effects on the Company could include, among other things,
business disruptions, increased costs, loss of business and other similar risks.

     Forward-Looking Information. The statements included in this report on Form
10-Q regarding future financial performance and results of operations and other
statements that are not historical facts are forward-looking statements within
the meaning of Section 27A of the Securities Act of 1933, as amended, and
Section 21E of the Securities Exchange Act of 1934, as amended. Statements to
the effect that the Company or management "anticipates," "believes,"
"estimates," "expects," "predicts," or "projects" a particular result or course
of events, or that such result or course of events "should" occur, and similar
expressions, are also intended to identify forward-looking statements. In
connection with such statements, it should be noted that the Company's
operations and financial results are subject to numerous risks, uncertainties
and assumptions, including but not limited to uncertainties related to industry
and market conditions, prices of crude oil and natural gas, foreign exchange and
currency fluctuations, political instability in foreign jurisdictions, the
ability of the Company to integrate newly acquired operations, the success of
the Company and material third party business partners or suppliers in
implementing their Year 2000 compliance plans and other factors discussed in
this quarterly report and in the Company's other filings with the Securities and
Exchange Commission. Should one or more of these risks or uncertainties
materialize, or should underlying assumptions prove incorrect, actual results
may vary materially from those stated.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

     The following discussion of the Company's market sensitive financial
instruments contains "forward-looking statements." All items described are
non-trading.

INTEREST RATE RISK

     There have been no material changes in the Company's market risk during the
nine months ended September 30, 1999. The Company currently has minimal interest
rate risk since a majority of the Company's long-term debt is fixed-rate and,
therefore, does not expose the Company to risk of earnings loss due to changes
in market interest rates. The Company is, however, subject to the risk of
fluctuating interest rates with respect to borrowings under the Credit
Agreement, since it provides for interest at variable rates.

FOREIGN EXCHANGE RISK

     The Company operates internationally, giving rise to exposure to market
risks from changes in foreign exchange rates to the extent that transactions are
not denominated in U.S. dollars. Wherever possible, the Company denominates its
contracts in U.S. dollars to mitigate the exposure to fluctuations in foreign
currencies. The Company uses forward exchange contracts as economic hedges of
exposed net investments in foreign entities in which that exposure exceeds $0.2
million and for which contracts in the appropriate currency are available. The
Company's foreign exchange contracts do not subject the Company to the risk of
changing rate movements because gains and losses on these contracts offset gains
and losses on the exposed investments being hedged. The forward exchange
contracts generally have maturities which do not exceed 31 days.
