                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS



1.      The consolidated financial statements of the Company included herein
        have been prepared without audit pursuant to generally accepted
        accounting principles and the rules and regulations of the Securities
        and Exchange Commission. Certain information and notes have been
        condensed or omitted pursuant to such rules and regulations and the
        Company believes that the disclosures included herein are adequate. It
        is suggested that these condensed financial statements be read in
        conjunction with the financial statements and related notes included in
        the Company's 1997 Annual Report to Stockholders incorporated by
        reference in the Form 10-K for the year ended December 31, 1997.

2.      In the opinion of the Company, the accompanying unaudited consolidated
        financial statements contain all adjustments and reclassifications,
        which are of a normal recurring nature, necessary to present fairly its
        financial position as of September 30, 1998 and December 31, 1997, and
        the results of its operations for the three and nine month periods ended
        September 30, 1998 and 1997 and its cash flows for the nine months ended
        September 30, 1998 and 1997.

3.      The results of operations for the three and nine month periods ended
        September 30, 1998 are not necessarily indicative of the results to be
        expected for the full year.

4.      The Company's adoption, effective January 1, 1998, of Statements of
        Financial Accounting Standards No. 130, "Reporting Comprehensive
        Income", and No. 132, "Employers' Disclosures about Pension and Other
        Postretirement Benefits", did not materially affect its financial
        statement disclosure. For the periods presented herein, the Company has
        no items of "other comprehensive income" as defined in Statement 130.

                     ROWAN COMPANIES, INC. AND SUBSIDIARIES

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



RESULTS OF OPERATIONS

Nine Months Ended September 30, 1998 Compared to
       Nine Months Ended September 30, 1997

The Company achieved net income of $119.6 million in the first nine months of
1998 compared to $99.0 million in the same period of 1997 as increased offshore
drilling day rates and improved manufacturing and aviation operations more than
offset higher provisions for income taxes. The prior period results were after
charges of $20 million from concluding the Company's turnkey business and $3.5
million from redeeming early certain 11 7/8% Senior Notes and incurred lower
income tax provisions due to available tax loss and credit carryforwards.

A comparison of the revenues and operating profit from drilling, manufacturing,
aviation and consolidated operations for the first nine months of 1998 and 1997,
respectively, is reflected below (dollars in thousands):

(1) Income from operations before deducting general and administrative expenses.


As reflected above, the Company's consolidated operating results increased by
43% to $192 million, or 34% of revenues, when comparing the first nine months of
1998 and 1997. Daywork drilling revenues increased by $49.5 million or 16% as
the Company's offshore fleet achieved 92% utilization during the first nine
months of 1998, compared to 99% in the same period of 1997, and a 24% increase
in average day rates between periods. Related expenses increased by $17.1
million or 12% between periods primarily as a result of higher wages and rig
mobilization costs.

The operating results for the first nine months of 1997 included a loss from
concluding the Company's turnkey drilling operations of approximately $20
million. The Company currently has no turnkey wells in progress nor any plans
for additional turnkey work at this time.

The 7% and 16% improvements shown above in the Company's manufacturing revenues
and profitability between periods primarily reflects the increased contribution
of the marine group. During the first nine months of 1998, the Company provided
design and components (a LeTourneau "kit") toward the construction of two new
Super 116 Class rigs. One kit was completed during the period and the other is
expected to be completed prior to year end. The division's external backlog was
$30.2 million at September 30, 1998. Manufacturing operations exclude
approximately $88 million of products and services provided to

the Company's drilling division during the first nine months of 1998, most of
which was attributable to construction progress on Rowan Gorillas V and VI,
compared to $49 million in the same period of 1997.

The 12% and 247% increases shown above in the Company's aviation revenues and
profitability between periods primarily reflects a more-than-doubling of forest
fire control services, the continued growth of Alaskan tourism and increased
flying for energy companies in the Gulf of Mexico and in connection with the
Company's commuter airline in Alaska. The Company's disposition in January 1998
of its 49% interest in the Dutch helicopter joint venture KLM ERA did not have a
material impact on its results of operations for the first nine months of 1998.


Three Months Ended September 30, 1998 Compared to
       Three Months Ended September 30, 1997

The Company generated net income of $32.5 million in the third quarter of 1998
compared to $54.3 million in the same period of 1997 as reduced offshore rig
utilization, primarily in the Gulf of Mexico, and higher provisions for income
taxes more than offset improved aviation operations. The prior period results
incurred lower income tax provisions due to available tax loss and credit
carryforwards.

A comparison of the revenues and operating profit from drilling, manufacturing,
aviation and consolidated operations for the third quarters of 1998 and 1997,
respectively, is reflected below (dollars in thousands):

As reflected above, the Company's consolidated operating results declined by
$15.9 million or 23% when comparing the third quarters of 1998 and 1997.
Drilling revenues decreased by $13.6 million or 12% as utilization of the
Company's offshore fleet fell to 84% during the third quarter of 1998, compared
to 99% in the third quarter of 1997, though average day rates increased by 6%
between periods. Related expenses increased by $5.4 million or about 10% between
periods primarily as a result of higher wages for operating personnel.

The decline in the Company's manufacturing revenues and profitability between
periods primarily reflects reduced mining equipment sales as a result of weak
commodity prices. The division's external backlog was $30.2 million at September
30, 1998. Manufacturing operations exclude approximately $37 million of products
and services provided to the Company's drilling division during the third
quarter of 1998, most of which was attributable to construction progress on
Rowan Gorillas V and VI, compared to $17 million in the same period of 1997.

The 15% and 103% increases shown above in the Company's aviation revenues and
profitability between periods primarily reflects increased flying in connection
with forest fire control services, Alaskan tourism, the Company's commuter
airline and for energy companies in the Gulf of Mexico.

Perceptible trends in the offshore drilling markets in which the Company is
currently operating and the number of Company-operated rigs in each of those
markets are as follows:

Perceptible trends in the aviation markets in which the Company is currently
operating and the number of Company-operated aircraft based in each of those
markets are as follows:





         AREA                    AIRCRAFT                        PERCEPTIBLE INDUSTRY TRENDS

Alaska                              69                  Normal seasonal decline

Gulf of Mexico                      46                  Generally stable flight support activity



The drilling and aviation markets in which the Company competes frequently
experience significant changes in supply and demand. Offshore drilling
utilization and day rates are primarily a function of the demand for drilling
services, as measured by the level of exploration and development expenditures,
and the supply of capable drilling equipment. These expenditures, in turn, are
affected by many factors such as existing and newly discovered oil and natural
gas reserves, political and regulatory policies, seasonal weather patterns,
contractual requirements under leases or concessions, trends in finding and
extraction costs and, probably most influential, oil and natural gas prices. The
Company's aviation operations are also affected by such factors, as flying in
support of offshore energy operations remains a major source of business and
Alaska operations are hampered each winter. The volatile nature of such factors
prevents the Company from being able to accurately predict whether existing
market conditions or the perceptible market trends reflected in the preceding
tables will continue. In response to fluctuating market conditions, the Company
can, as it has done in the past, relocate its drilling rigs and aircraft from
one geographic area to another, but only when such moves are economically
justified.

In recent months, the prolonged weakness in oil prices has led to a reduction in
drilling, primarily impacting jack-ups in the Gulf of Mexico. As some energy
companies have suspended portions of their drilling programs and announced
anticipated reductions in their 1998 and 1999 drilling budgets, the Company has
experienced curtailed drilling assignments and, at least partly due to its
efforts to maintain day rates, lower utilization of its rig fleet. Currently,
only five of the Company's Gulf of Mexico rigs are working and generally at day
rates well below those obtained during the just-completed third quarter. At
current levels, the Company can continue to operate profitably, though at a
level well below that experienced during the first nine months of 1998. There
can be no assurance that the Company's operations will not be more adversely
affected should current market conditions persist or that such conditions will
not deteriorate further.

The Company's manufacturing operations are considerably less volatile than its
drilling and aviation operations and, given current order backlog and barring
unforeseen circumstances, should continue to contribute positive operating
results throughout the remainder of 1998.

Stockholders' equity                                $  735,149       $  653,098
Long-term debt/total capitalization                        .25              .28



Reflected in the comparison above are the effects in the first nine months of
1998 of net cash provided by operations of $197.6 million, capital expenditures
of $180.1 million, proceeds from borrowings of $43.1 million, repayments of
borrowings of $36.2 million, payments to acquire treasury stock of $45.9 million
and cash proceeds from the disposition of the Company's 49% interest in KLM ERA
Helicopters of $19.6 million.

Capital expenditures during the first nine months of 1998 were primarily related
to construction of Rowan Gorilla V and Rowan Gorilla VI , each being an enhanced
version of the Company's Gorilla Class jack-ups featuring a combination drilling
and production capability. Gorilla V is undergoing final outfitting at the
Company's Sabine Pass, Texas facility and should be completed and commence
operations in the North Sea during the fourth quarter. The Company has financed
$153.1 million of the cost of Gorilla V through two fixed rate bank notes
guaranteed by the Maritime Administration of the U. S. Department of
Transportation under its Title XI Program. The notes require semiannual
repayments beginning in January 1999, with final payments due in July 2010, and
bear interest as follows: $67 million at 6.94% and $86.1 million at 6.15%.

Construction of Gorilla VI is progressing at the Company's Vicksburg,
Mississippi shipyard and should be completed by mid-2000. The Company has
obtained Title XI bank financing for up to $171 million of the cost of Gorilla
VI on terms and conditions similar to those obtained for Gorilla V.

The Company has begun ordering long lead-time items for Rowan Gorilla VII and
expects construction to be completed about one year following delivery of
Gorilla VI. The Company intends to pursue outside financing for Gorilla VII if
necessary, but believes that internally generated working capital may be
sufficient to fund its construction. There can be no assurance that working
capital will be adequate throughout the period required to complete construction
or that outside financing will be available. The Company expects the total
construction cost of Gorillas V, VI and VII will be in the range of $550-600
million.

The Company estimates remaining 1998 capital expenditures will be between $50
million and $60 million, including approximately $35-45 million for Gorillas V,
VI and VII. The Company may also spend amounts to acquire additional aircraft as
market conditions justify and to upgrade existing offshore rigs and
manufacturing facilities.

In March 1998, the Company repaid the balance of $36.2 million of promissory
notes originally issued in February 1994 in connection with the acquisition of
its manufacturing operations. 



                                      -11-

At September 30, 1998, the Company had available $45 million under a $155
million bank revolving credit facility maturing in October 2000. The $110
million outstanding under the credit line bore interest at 6.03% on September
30, 1998.

Based upon current operating levels and the previously discussed market trends,
management believes that 1998 operations, together with existing working capital
and available financial resources, will generate sufficient cash flow to sustain
planned capital expenditures and debt service requirements at least through the
remainder of 1998.

At September 30, 1998, approximately $153 million of the Company's retained
earnings was available for the payment of dividends under the most restrictive
provisions of the Company's debt agreements.

On October 22, 1998, the Company expanded its Share Repurchase Program to
include up to eight million shares of its outstanding Common Stock. Since the
Program's inception in June 1998, the Company has repurchased 3,451,400 shares.

The Company believes that its exposure to potential year 2000 ("Y2K")
computer-related problems is limited and the costs associated with readying its
information systems and computer-controlled equipment will not materially impact
its financial position or results of operations. Over the past several years,
the Company has devoted substantial efforts towards upgrading and enhancing its
drilling and aviation information systems as a matter of course. Such
modifications necessarily contemplated Y2K compliance, the cost of which has
been expensed as incurred but is not separately identifiable. These upgrades and
enhancements are substantially complete and the Company's drilling and aviation
information systems should be fully Y2K compliant by the end of this year.
Modifications to the Company's manufacturing information systems have been
undertaken only during the past two to three years. The Company expects the cost
of Y2K compliance for its manufacturing systems will be approximately $2.8
million, $1.3 million of which has been expensed to date, and that all necessary
modifications will be completed by mid-1999. The Company will continue to assess
and test its computer-controlled equipment for Y2K compatibility, but has
heretofore discovered no significant deficiencies. The Company's operations are
not highly dependent upon any single customer or vendor and the Company believes
that the risk of a material interruption in its business as a result of Y2K
software problems associated with a single customer or vendor is extremely
remote. The Company has not yet deemed necessary any Y2K contingency plans, but
will continue to monitor its own Y2K status as well as that of its customers and
vendors and, if warranted, develop any necessary contingency plans.
