                   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 June 30, 1998 and December 31, 1997, and the
        results of its operations for the three and six month periods ended June
        30, 1998 and 1997 and its cash flows for the six months ended June 30,
        1998 and 1997.




3.      The results of operations for the three and six month periods ended June
        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

Six Months Ended June 30, 1998 Compared to
         Six Months Ended June 30, 1997

The Company achieved net income of $87.1 million in the first half of 1998
compared to $44.7 million in the same period of 1997. This enhanced performance
resulted primarily from increased offshore drilling day rates and improved
manufacturing operations. 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.

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

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


As reflected above, the Company's consolidated operating results more than
doubled to $140 million, or 36% of revenues, when comparing the first halves of
1998 and 1997. Day rate drilling revenues increased by $63.1 million or 33% as
the Company's offshore fleet achieved 97% utilization during the first half of
1998, compared to 99% in the first half of 1997, and a 34% increase in average
day rates between periods. Related expenses increased by $11.8 million or 13%
between periods primarily as a result of higher wages and rig mobilization 
costs.

First half 1997 operating results 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 54% improvement shown above in the Company's manufacturing profitability
between periods primarily reflects the increased contribution of the marine
group. During the first half of 1998, the Company provided design and components
("LeTourneau kit") toward the construction of two new Super 116 Class rigs. One
kit was essentially complete at June 30, 1998 and the other should be completed
by year end. The division's external backlog was $47.4 million at June 30, 1998.
Manufacturing operations exclude approximately $51 million of products and
services provided to the Company's drilling division during the 


                                      -8-
   10

first half of 1998, most of which was attributable to construction progress on
Rowan Gorillas V and VI, compared to $32 million in the same period of 1997.

The aviation operating results in both periods reflect the normal reduced flying
activity in Alaska throughout much of the first four months of the year,
although the 1998 results were hampered primarily due to higher wages and
aircraft maintenance costs. 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 first half 1998 results of operations.


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

The Company achieved net income of $44.4 million in the second quarter of 1998
compared to $40.6 million in the same period of 1997. This enhanced performance
resulted primarily from increased offshore drilling day rates and improved
manufacturing operations.

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

As reflected above, the Company's consolidated operating results improved by
$19.7 million or 38% when comparing the second quarters of 1998 and 1997. Day
rate drilling revenues increased by $28.5 million or 28% as the Company's
offshore fleet achieved 95% utilization during the second quarter of 1998,
compared to 100% in the second quarter of 1997, and a 31% increase in average
day rates between periods. Related expenses increased by $8.7 million or about
18% between periods primarily as a result of higher wages and rig mobilization 
costs.

The 66% improvement shown above in the Company's manufacturing profitability
between periods primarily reflects the increased contribution of the marine
group. During the second quarter of 1998, the Company completed one of the two
Super 116 Class rig kits it sold in 1997. The second kit should be completed by
year-end 1998. The division's external backlog was $47.4 million at June 30,
1998. Manufacturing operations exclude approximately $29 million of products and
services provided to the Company's drilling division during the second quarter
of 1998, most of which was attributable to construction progress on Rowan
Gorillas V and VI, compared to $16 million in the same period of 1997.

The Company's aviation operations experienced the normal seasonal improvement in
flying activity in Alaska during both periods, although the 1998 results were
hampered primarily due to higher wages and aircraft maintenance costs.

markets are as follows:

Alaska                              70                  Normal seasonal improvement

Gulf of Mexico                      49                  Moderately improving market conditions


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 reduced their
1998 drilling budgets, the Company has experienced curtailed drilling
assignments and, in many instances, has had to accept lower day rates in an
effort to maintain utilization of its rig fleet. Many of the Company's Gulf of
Mexico rigs are currently working at day rates well below those obtained during
the just-completed second quarter. At current levels, the Company should
continue to operate profitably. However, there can be no assurance that the
Company's operations will not be more adversely affected should current
conditions persist or that market 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.

LIQUIDITY AND CAPITAL RESOURCES

A comparison of key balance sheet figures and ratios as of June 30, 1998 and
December 31, 1997 is as follows (dollars in thousands):

Reflected in the comparison above are the effects in the first half of 1998 of
net cash provided by operations of $122.3 million, capital expenditures of $115
million, proceeds from borrowings of $40.6 million, repayments of borrowings of
$36.2 million and proceeds from the disposition of the Company's 49% interest in
KLM ERA Helicopters of $19.6 million.

Capital expenditures during the first half 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 recently completed its relocation from the
Company's Vicksburg, Mississippi shipyard to its Sabine Pass, Texas facility for
final outfitting 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 should be completed during the second quarter of 2000
and the Company is pursuing outside financing 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 to 600
million.

The Company estimates remaining 1998 capital expenditures will be between $90
million and $100 million, including approximately $75-80 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-
   13
At June 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 6.06% on June 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 June 30, 1998, approximately $137 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 June 16, 1998, the Company instituted a program of repurchasing up to five
percent of its outstanding Common Stock. At July 31, 1998, the Company had
repurchased more than two percent of its outstanding shares.

The Company believes that its exposure to potential year 2000 software problems
is limited and the costs associated with readying its information systems will
not materially impact its financial position or results of operations. The
Company expects to substantially complete modifications to its information
systems during 1998 and will expense such costs as they are incurred.
