                              SEACOR HOLDINGS INC.
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (unaudited)



1.      Basis of Presentation

The condensed consolidated financial information for the three months ended
March 31, 2005 and 2004 has been prepared by the Company and was not audited by
its independent registered public accounting firm. The condensed consolidated
financial statements include the accounts of SEACOR Holdings Inc. and its
majority owned subsidiaries. In the opinion of management, all adjustments
(consisting of normal recurring adjustments) have been made to present fairly
the Company's financial position as of March 31, 2005 and its results of
operations and cash flows for the three months ended March 31, 2005 and 2004.
Results of operations for the interim periods presented are not necessarily
indicative of the operating results for the full year or any future periods.

Certain information and footnote disclosures normally included in financial
statements prepared in accordance with generally accepted accounting principles
have been condensed or omitted. These condensed consolidated financial
statements should be read in conjunction with the financial statements and
related notes thereto included in the Company's Annual Report on Form 10-K for
the fiscal year ended December 31, 2004.

Unless the context otherwise indicates, any references in this Quarterly Report
on Form 10-Q to the "Company" refer to SEACOR Holdings Inc. and its consolidated
subsidiaries, and any references in this Quarterly Report on Form 10-Q to
"SEACOR" refer to SEACOR Holdings Inc.

Certain reclassifications of prior period information have been made to conform
to the current period presentation.

2.      Seabulk Merger

On March 16, 2005, SEACOR announced its signing of a definitive merger agreement
with Seabulk International, Inc. ("Seabulk"). The Boards of Directors of both
companies have unanimously approved the transaction. Under the terms of the
merger agreement, Seabulk's stockholders will, subject to limited adjustments,
receive 0.2694 of a share of SEACOR common stock, par value $0.01 per share
("Common Stock"), plus cash of $4.00 for each issued and outstanding share of
Seabulk common stock. In certain circumstances, the portion of the merger
consideration payable in cash may be reduced and shares of Common Stock, having
a value on the closing date equal to the cash reduction, may be substituted
therefor.

The aggregate equity value of the transaction is approximately $532.0 million,
based on SEACOR issuing 6,641,270 shares of Common Stock at a closing share
price of $65.28 on March 16, 2005 plus additional cash consideration of $98.6
million. In addition, approximately $471.0 million in net debt obligations will
be assumed by SEACOR.

The merger is expected to close in accordance with the terms of the merger
agreement by the end of the second quarter of 2005 subject to the approval by
Seabulk's stockholders of the merger, the approval of SEACOR's stockholders of
the issuance of shares of Common Stock to effect the merger, and the
satisfaction of customary closing conditions. On April 22, 2005, SEACOR was
granted early termination of the waiting period under Hart-Scott-Rodino
Antitrust Improvements Act.

3.      Equipment Acquisitions and Dispositions

Equipment delivered to the Company during the three months ended March 31, 2005
included 25 new dry cargo covered hopper barges, 7 new chemical tank barges and
1 new offshore support vessel for aggregate consideration of $17.9 million. The
Company sold 10 vessels and other equipment during the three months ended March
31, 2005 for aggregate consideration of $104.6 million.

4.      Era Aviation, Inc. Acquisition

On December 31, 2004, the Company acquired all of the issued and outstanding
shares of Era Aviation, Inc. ("Era") for $118.1 million. As a result of this
transaction, the Company acquired 81 helicopters and 16 fixed wing aircraft. The
acquired fixed wing business is presently being marketed for sale. The final
purchase price allocation has not been completed and is subject to, among other
things, working capital adjustments and the fair value determination of the
fixed wing business. The Company does not expect this transaction to result in
the recognition of goodwill.

The operating results of the fixed wing business, including $8.5 million of
operating revenues earned in the three months ended March 31, 2005, have been
reported as "Discontinued Operations" in the Company's "Statement of
Operations." At March 31, 2005, assets and related liabilities of the fixed wing
business, amounting to $23.0 million and $6.5 million, respectively, and one
acquired Era helicopter, valued at $2.1 million, were held for sale by the
Company. Held for sale assets and related liabilities have been reported in
"Prepaid expenses and other current assets" and "Other current liabilities",
respectively, in the Condensed Consolidated Balance Sheets.


5.      Commitments

The Company's unfunded capital commitments as of March 31, 2005 for 4 new and 4
used offshore support vessels, 20 new dry cargo covered hopper barges, 9 new
chemical tank barges, 32 new helicopters and other equipment totaled $356.5
million. Of these commitments, the Company has the right to terminate its
purchase obligation relating to 20 helicopters without liability other than the
payment of liquidated damages. Deliveries of the offshore support vessels, dry
cargo covered hopper barges, chemical tank barges and other equipment are
expected throughout 2005. Deliveries of the 32 helicopters are expected from
2005 through 2009.

In addition to the purchase commitments discussed above, the Company has placed
refundable deposits on 13 additional new helicopters.

The Company has guaranteed the payment of amounts owed by certain of its joint
ventures under vessel charter agreements that expire through 2009. In addition,
the Company has guaranteed amounts owed by certain of its joint ventures for a
banking facility and a performance guarantee. As of March 31, 2005, the total
amount guaranteed by the Company was $15.7 million.

6.       Long-Term Debt

As of March 31, 2005, the Company had $196.2 million available under its five
year, non-reducing, unsecured $200.0 million revolving credit facility that
terminates in February 2007.

7.      Deferred Income Taxes

As a result of the American Jobs Creation Act of 2004, the Company believes it
will be in the position to repatriate, for a limited time, accumulated foreign
earnings at an effective federal tax rate of 5.25%, which would result in tax
obligations significantly less than the deferred taxes previously provided for
its unremitted earnings of foreign subsidiaries. The Company is exploring the
full impact of the legislation and will finalize its repatriation plan during
2005. In accordance with FASB Staff Position FAS 109-2, the Company will
recognize the income tax benefit of this special one-time dividends received
deduction during the period that the Company has decided on a plan for
repatriation.

8.      Stock and Debt Repurchases

During the three months ended March 31, 2005, the Company acquired a total of
84,647 shares of Common Stock for treasury at an aggregate cost of $5.6 million.
As of March 31, 2005, $37.7 million of repurchase authority granted by the
Company's Board of Directors remains available for acquisition of additional
shares of Common Stock, the Company's 7.2% Senior Notes Due 2009 ("7.2% Notes")
and its 5-7/8% Senior Notes due 2012 ("5-7/8% Notes"). Securities are acquired
from time to time through open market purchases, privately negotiated
transactions or otherwise, depending on market conditions.

9.      Earnings (Loss) Per Common Share

Basic earnings (loss) per common share were computed based on the weighted
average number of common shares issued and outstanding during the relevant
periods. Diluted earnings (loss) per common share were computed based on the
weighted average number of common shares issued and outstanding plus all
potentially dilutive common shares that would have been outstanding in the
relevant periods assuming the vesting of restricted stock grants and the
issuance of common shares for stock options and convertible subordinated notes
through the application of the treasury stock and if-converted methods. Diluted
earnings (loss) per common share exclude certain options and share awards,
totaling 83,560 and 327,454 in the three months ended March 31, 2005 and 2004,
respectively, as the effect of their inclusion in the computation would have
been antidilutive.

10.      Comprehensive Income

For the three months ended March 31, 2005 and 2004, comprehensive income (loss)
was $17.6 million and ($0.9 million), respectively. Other comprehensive income
(loss) consisted of gains and losses from foreign currency translation
adjustments and unrealized holding gains and losses on available-for-sale
securities.


11.     Stock Compensation

Under Statement of Financial Accounting Standards No. 123 ("SFAS 123"),
companies could either adopt a "fair value method" of accounting for its stock
based compensation plans or continue to use the "intrinsic value method" as
prescribed by APB Opinion No. 25. The Company has elected to continue accounting
for its stock compensation plans using the intrinsic value method. Had
compensation costs for the plans been determined using a fair value method
consistent with SFAS 123, the Company's net income (loss) and earnings per share
would have been reduced to the following pro forma amounts:




                                                                                            For the Three Months
                                                                                               Ended March 31,
                                                                                           ------------------------
(in thousands, except per share data)                                                         2005        2004

Basic earnings (loss) per common share:

The effects of applying a fair value method consistent with SFAS 123 in this pro
forma disclosure are not indicative of future events and the Company anticipates
that it will award additional stock based compensation in future periods.

12.     New Accounting Pronouncement

On December 16, 2004, the Financial Accounting Standards Board (FASB) issued
FASB Statement No. 123 (revised 2004), Share-Based Payment, which is a revision
of FASB Statement No. 123, Accounting for Stock-Based Compensation. Statement
123 (R) supersedes APB Opinion No. 25, Accounting for Stock Issued to Employees,
and amends FASB Statement No. 95, Statement of Cash Flows. Statement 123 (R)
requires all share-based payments to employees, including grants of employee
stock options, to be recognized in the income statement based on their fair
values. The impact of adopting Statement 123 (R) cannot be predicted at this
time because it will depend on levels of share-based payments granted in the
future. However, had the Company adopted Statement 123 (R) in prior periods, the
impact of that standard would have approximated the impact of the SFAS 123
disclosure of pro forma net income and earnings per share presented in Note 11.
The Company will adopt the provisions of Statement 123 (R) on January 1, 2006
using the "modified prospective" approach, recognizing compensation expense for
all unvested employee stock options as of that date and for all subsequent
employee stock options granted thereafter.

13.     Segment Information

Accounting standards require public business enterprises to report information
about each of their operating business segments that exceed certain quantitative
thresholds or meet certain other reporting requirements. Operating business
segments have been defined as a component of an enterprise about which separate
financial information is available and is evaluated regularly by the chief
operating decision maker in deciding how to allocate resources and in assessing
performance. Certain reclassifications of prior period information have been
made to conform to the current period's reportable segment presentation. The
Company's basis of measurement of segment profit or loss has not changed from
those previously described in the Company's Annual Report on Form 10-K for the
fiscal year ended December 31, 2004.

achievements discussed or implied by such forward-looking statements. Such
risks, uncertainties and other important factors include, among others: the
cyclical nature of the oil and gas industry, the operation of Offshore Marine
Services and Helicopter Services in a highly competitive environment, changes in
foreign political, military and economic conditions, the dependence of Offshore
Marine Services and Helicopter Services on several customers, industry fleet
capacity, the ongoing need to replace aging vessels, restrictions imposed by the
Shipping Acts and Aviation Acts on the amount of foreign ownership of the
Company's Common Stock, safety record requirements related to Offshore Marine
Services and Helicopter Services, changes in foreign and domestic oil and gas
exploration and production activity, vessel and helicopter-related risks of
Offshore Marine Services and Helicopter Services, effects of adverse weather
conditions and seasonality on Helicopter Services, dependence of spill response
revenue on the number and size of spills and upon continuing government
regulation in this area and our ability to comply with such regulation and other
governmental regulation, changes in NRC's OSRO classification, effects of
adverse weather and river conditions and seasonality on inland river operations,
the level of grain export volume, the effect of fuel prices on barge towing
costs, variability in freight rates for inland river barges, liability in
connection with providing spill response services, the effect of international
economic and political factors in inland river operations, the intense
competition faced by Inland River Services, adequacy of insurance coverage,
currency exchange fluctuations, the attraction and retention of qualified
personnel by the Company, and various other matters, many of which are beyond
the Company's control and other factors as described at the end of Item 7
(Management's Discussion and Analysis of Financial Condition and Results of
Operations) of the Company's Form 10-K for the fiscal year ended December 31,
2004. The words "expect," "anticipate," "estimate," "project," "intend,"

forward-looking statements. Forward-looking statements speak only as of the date
of the document in which they are made. We disclaim any obligation or
undertaking to provide any updates or revisions to any forward-looking statement

     Overview

The table above provides an analysis of the Company's consolidated statements of
operations for each quarter indicated. See "Item 1. Financial Statements - Note
13. Segment Information" included in Part I for additional financial information
about the Company's business segments. Additional discussions of results of
operations by business segment are presented below. The Company's operations are
divided among the following four business segments: "Offshore Marine Services;"
"Environmental Services;" "Inland River Services;" and "Helicopter Services."
The Company also has activities that are referred to and described under
"Other." "Other" primarily includes equity in earnings of 50% or less owned
companies unrelated to our reportable business segments and our "Fixed Base
Operation" acquired in the December 31, 2004 Era acquisition (as described in
Note 4 to the financial statements). Our Fixed Base Operation sells fuel and
ground services to transient corporate aircraft at the Ted Stevens Anchorage
International Airport.

Consolidated operating revenues increased 72%, or $69.2 million, to $165.2
million in the three months ended March 31, 2005 ("Current Year Quarter") from
the three months ended March 31, 2004 ("Prior Year Quarter"). Market conditions
improved and gains from the sale of vessels increased in Offshore Marine
Services. Spill response activities increased in Environmental Services. A
significant number of new barges were acquired and entered operations in Inland
River Services. Fleet size also grew significantly in Helicopter Services,
primarily resulting from the Era acquisition.

In the Current Year Quarter, consolidated net income was $18.6 million as
compared to a consolidated net loss of $3.0 million in the Prior Year Quarter.
Increased operating profits earned by Offshore Marine Services, Environmental
Services and Inland River Services were partly offset by increased operating
losses of Helicopter Services. The Company's equity interest in the earnings of
50% or less owned companies also improved in the Current Year Quarter due
principally to increased Offshore Marine Services' joint venture profits.

Operating Revenues. Operating revenues increased significantly in the Current
Year Quarter. Rates per day worked improved worldwide. Utilization improved for
vessels in many of our operating regions. Operating revenues also improved as a
result of fleet modernization, a net increase in the number of vessels entering
time charter-out service upon concluding bareboat-out charter arrangements and a
strengthening between years in the Pound Sterling currency relative to the U.S.
dollar with respect to Offshore Marine Services' North Sea operations.

Operating Income (Loss). Operating income improved due to those factors
affecting operating revenues, a $9.5 million increase in gains on asset sales
and a $0.9 million decline in administrative and general expenses that resulted
from staff reductions. Improved operating income was partly offset by increased
vessel operating expenses between years due principally to increased (i) seamen
redundancy costs associated with workforce reductions, (ii) repair and
maintenance expenses on towing and anchor handling towing supply vessels and
(iii) fuel costs associated with the Company's North Sea operations.

Although reported operating revenues increased due to the strengthening in the
Pound Sterling currency relative to the U.S. dollar, currency exchange rate
fluctuations had no material effect on operating income, because Offshore Marine
Services also pays its North Sea expenses in Pounds Sterling.

Operating Revenues. Results improved in the Current Year Quarter due largely to
increased spill response activities, retainer fees and expanded services
internationally. Environmental Services continued its response in the Current
Year Quarter to a major oil spill on the Delaware River that began in December
2004. Activities connected with that spill declined from the fourth quarter of
2004 and are expected to continue at lower levels in the second quarter of 2005.
Retainer fees charged by the Company for ensuring by contract the availability
of Environmental Services' response services and equipment to customers were
increased in the Current Year Quarter. Environmental Services now also provides
oil spill response services in the Caspian region.

The operating results of Environmental Services are very dependent on the number
of spill responses in a given period and the magnitude of each spill.
Consequently, spill response revenues and related income can vary materially
between comparable periods, and the operating revenues earned in any one period
are not indicative of a trend or of anticipated results in future periods. Spill
response activities approximated 51% of Environmental Services operating
revenues in the Current Year Quarter as compared to 27% in the Prior Year
Quarter.

Operating Income. Operating income increased in the Current Year Quarter due to
improved operating revenues and profitability on spill response and retainer
activities.

Operating Revenues. Results improved in the Current Year Quarter due largely to
fleet additions and improved freight rates. Inland River Services' owned and
chartered-in barge fleet grew approximately 60% from 564 barges at March 31,
2004 to 901 barges at March 31, 2005. Inland River Services also acquired a
majority interest in 3 towboats in July 2004. Freight rates improved as a result
of increased demand for non-grain shipping capacity and a decline in barge
availability within the industry caused by adverse river conditions.

Operating Income. Operating income increased in the Current Year Quarter due to
barge fleet expansion and improved profitability that resulted from increased
freight rates. These operating income improvements were partly offset by higher
operating expenses. Towing expenses increased in the Current Year Quarter due
primarily to higher fuel costs.

Operating Revenues. Fleet expansion resulting primarily from the December 31,
2004 Era acquisition improved operating revenues in the Current Year Quarter.
Era owned 81 helicopters at acquisition.

Operating Loss. Due to the seasonal nature of tourism in Alaska, 19 helicopters
were idle for most of the winter. In addition, 10 helicopters customarily
engaged in fire-fighting service during the summer months were idle for most of
the Current Year Quarter. Helicopter Services also schedules maintenance during
the off-season for these 29 helicopters and hence maintains its staff to prepare
this equipment for spring and summer operations. Inventory is used in
conjunction with this preparation and its cost is expensed during the period in
which it is consumed. The Current Year Quarter includes approximately $0.7
million of nonrecurring charges, principally associated with the integration of
Era.

     Income Taxes

As a result of the American Jobs Creation Act of 2004, the Company believes it
will be in the position to repatriate, for a limited time, accumulated foreign
earnings at an effective federal tax rate of 5.25%, which would result in tax
obligations significantly less than the deferred taxes previously provided for
its unremitted earnings of foreign subsidiaries. The Company is exploring the
full impact of the legislation and will finalize its repatriation plan during
2005. In accordance with FASB Staff Position FAS 109-2, the Company will
recognize the income tax benefit of this special one-time dividends received
deduction during the period that the Company has decided on a plan for
repatriation.

     Loss from Discontinued Operations

On December 31, 2004, the Company acquired 16 fixed wing aircraft in the Era
acquisition. Management has committed to the disposal of this fixed wing
business and is actively marketing it for sale. Its operating results, a slight
loss during the Current Year Quarter, have been reported as "Discontinued
Operations" in the Consolidated Results of Operations. At March 31, 2005, assets
and related liabilities of the fixed wing business, amounting to $23.0 million
and $6.5 million, respectively, and one acquired Era helicopter, valued at $2.1
million, were held for sale by the Company. Held for sale assets and related
liabilities have been reported in "Prepaid expenses and other current assets"
and "Other current liabilities", respectively, in the Condensed Consolidated
Balance Sheets.

LIQUIDITY AND CAPITAL RESOURCES

     General

The Company's ongoing liquidity requirements arise primarily from the funding of
working capital needs, acquisition, construction or improvement of equipment,
repayment of debt obligations, repurchase of Common Stock and purchase of other
investments. Principal sources of liquidity are cash balances, marketable
securities, construction reserve funds, cash flows from operations and
borrowings under the Company's revolving credit facility although, from time to
time, the Company may issue debt, shares of Common Stock, preferred stock, or a
combination thereof, or sell vessels and other assets to finance the acquisition
of equipment and businesses or make improvements to existing equipment. Fleet
size, rates of hire and utilization of the Company's offshore support vessels,
inland barges and helicopters and the number and severity of oil spills managed
by Environmental Services primarily determine the Company's levels of operating
cash flows.

     Summary of Cash Flows

     Operating Activities

Cash flows from operating activities increased in the Current Year Quarter due
primarily to improved operating results in Offshore Marine Services,
Environmental Services and Inland River Services (see Consolidated Results of
Operations discussion above), and the favorable effect of changes in working
capital.

     Investing Activities

Cash flows from investing activities increased in the Current Year Quarter
primarily from increased proceeds from equipment and marketable securities sales
and decreased deposits in construction reserve funds for future purchase of
vessels or barges. These additional cash flows were partially offset by an
increase in equipment purchases. The Company sold 10 vessels and other equipment
and acquired 25 new dry cargo covered hopper barges, 7 new chemical tank barges
and 1 new offshore support vessel in the Current Year Quarter.


                                       13

The Company's unfunded capital commitments as of March 31, 2005 for 4 new and 4
used offshore support vessels, 20 new dry cargo covered hopper barges, 9 new
chemical tank barges, 32 new helicopters and other equipment totaled $356.5
million. Of these commitments, the Company has the right to terminate its
purchase obligation relating to 20 helicopters without liability other than the
payment of liquidated damages. Deliveries of the offshore support vessels, dry
cargo covered hopper barges, chemical tank barges and other equipment are
expected throughout 2005. Deliveries of the 32 helicopters are expected from
2005 through 2009.

In addition to the purchase commitments discussed above, the Company has placed
refundable deposits on 13 additional new helicopters.

     Financing Activities

Cash flows used in financing activities are comparable between periods.
Additional cash used to purchase Common Stock was offset by additional cash
received on exercise of stock options.

During the three months ended March 31, 2005, the Company acquired a total of
84,647 shares of Common Stock for treasury at an aggregate cost of $5.6 million.
As of March 31, 2005, $37.7 million of repurchase authority granted by the
Company's Board of Directors remains available for acquisition of additional
shares of Common Stock and the Company's 7.2% Notes and its 5-7/8% Notes.
Securities are acquired from time to time through open market purchases,
privately negotiated transactions or otherwise, depending on market conditions.

     Financial Position

Total assets of the Company increased 1% to $1.8 billion at quarter end. The
Company's combined cash, available-for-sale securities and construction reserve
funds increased 24% to $615.2 million and represented 35% of total assets at
quarter end. Net property and equipment decreased 9% to $845.4 million and
represented 48% of total assets at quarter end. Net working capital increased
20% to $545.5 million. Long-term debt remained constant at $582.4 million
between March 31, 2005 and December 31, 2004.

As of March 31, 2005, the Company had $196.2 million available under a five
year, non-reducing, unsecured $200.0 million revolving credit facility that
terminates in February 2007.

     Short and Long-Term Liquidity Requirements

The Company anticipates it will continue to generate positive cash flows from
operations in the near term and these cash flows will be adequate to meet the
Company's working capital requirements and contribute toward defraying costs of
its capital expenditures. As in the past and in further support of the Company's
acquisition and capital expenditure programs, the Company intends to sell
vessels, enter into sale and leaseback transactions for vessels, utilize
construction reserve funds, utilize borrowing capacity under its revolving
credit facility, or a combination thereof. To the extent the Company relies on
existing cash balances, proceeds from the sale of available-for-sale securities
or construction reserve funds, the Company's liquidity would be reduced.

The Company's long-term liquidity is dependent upon its ability to generate
operating cash flows sufficient to meet its requirements for working capital,
capital expenditures and a reasonable return on shareholders' investment. The
Company believes that earning such operating profits will permit it to maintain
its access to favorably priced debt, equity and off-balance sheet financing
arrangements.

     Seabulk Merger

On March 16, 2005, SEACOR and Seabulk International, Inc. announced that they
had signed a definitive merger agreement. The Boards of Directors of both
companies unanimously approved the transaction. Under the terms of the merger
agreement, Seabulk's stockholders will, subject to limited adjustments, receive
0.2694 of a share of Common Stock plus cash of $4.00 for each issued and
outstanding share of Seabulk common stock, which represents a 29% premium over
Seabulk's closing share price on March 16, 2005 (based on SEACOR's closing share
price on such date). In certain circumstances, the portion of the merger
consideration payable in cash may be reduced and shares of Common Stock, having
a value on the closing date equal to the cash reduction, may be substituted
therefor.


                                       14

The aggregate equity value of the transaction is approximately $532.0 million,
based on SEACOR issuing 6,641,270 shares of Common Stock at a closing share
price of $65.28 on March 16, 2005 plus additional cash consideration of $98.6
million. In addition, approximately $471.0 million in net debt obligations will
be assumed by SEACOR. Cash required of SEACOR to complete the merger with
Seabulk is estimated at $108 million, including approximately $9.0 million of
transaction fees and expenses. SEACOR expects to use existing cash balances,
borrowings under its revolving credit facility, or a combination thereof to fund
the cash requirements of the merger with Seabulk.

The merger is expected to close by the end of the second quarter of 2005,
subject to approval by Seabulk's stockholders of the merger and SEACOR's
stockholders of the issuance of shares of Common Stock in the merger and the
satisfaction of customary closing conditions, in accordance with terms of the
merger agreement. As part of the transaction, entities associated with DLJ
Merchant Banking Partners III, L.P. and Carlyle/Riverstone Global Energy and
Power Fund I, L.P., who collectively own approximately 75% of Seabulk's common
shares, have entered into an agreement to support the transaction.

On April 22, 2005, SEACOR and Seabulk announced that they had been granted early
termination of the waiting period under the Hart-Scott-Rodino Antitrust
Improvements Act. This means that one of the key conditions for the closing of
the merger agreement between the two companies has been satisfied.

In connection with the proposed merger, SEACOR has filed with the Securities and
Exchange Commission a Registration Statement on Form S-4 that includes a joint
proxy statement of SEACOR and Seabulk and that also constitutes a prospectus for
Common Stock to be issued in the merger.

With a fleet of 147 vessels, including 10 Jones Act U.S. product tankers, 2
foreign-flag product tankers, 109 offshore support vessels and 26 tugs, Seabulk
is a leading provider of marine support and transportation services, primarily
to the energy and chemical industries.

     Contingencies

In the normal course of its business, the Company becomes involved in various
litigation matters including, among other things, claims by third parties for
alleged property damages, personal injuries and other matters. While the Company
believes it has meritorious defenses against these claims, management has used
estimates in determining the Company's potential exposure and has recorded
reserves in its financial statements related thereto where appropriate. It is
possible that a change in the Company's estimates of that exposure could occur,
but the Company does not expect such changes in estimated costs will have a
material effect on the Company's financial position or results of its
operations.

     New Accounting Pronouncement

On December 16, 2004, the Financial Accounting Standards Board (FASB) issued
FASB Statement No. 123 (revised 2004), Share-Based Payment, which is a revision
of FASB Statement No. 123, Accounting for Stock-Based Compensation. Statement
123 (R) supersedes APB Opinion No. 25, Accounting for Stock Issued to Employees,
and amends FASB Statement No. 95, Statement of Cash Flows. Statement 123 (R)
requires all share-based payments to employees, including grants of employee
stock options, to be recognized in the income statement based on their fair
values. The impact of adopting Statement 123 (R) cannot be predicted at this
time because it will depend on levels of share-based payments granted in the
future. However, had the Company adopted Statement 123 (R) in prior periods, the
impact of that standard would have approximated the impact of the SFAS 123
disclosure of pro forma net income and earnings per share presented in note 11
of the condensed consolidated financial statements included in Item 1 of this
Quarterly Report. The Company will adopt the provisions of Statement 123 (R) on
January 1, 2006 using the "modified prospective" approach, recognizing
compensation expense for all unvested employee stock options as of that date and
for all subsequent employee stock options granted thereafter.

ITEM 3.   QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

There has been no significant change in the Company's exposure to market risk
during the three-month period ended March 31, 2005. For discussion of the
Company's exposure to market risk, refer to Item 7A, Quantitative and
Qualitative Disclosures about Market Risk, contained in the Company's Annual
Report on Form 10-K for the fiscal year ended December 31, 2004.

ITEM 4.   CONTROLS AND PROCEDURES

The Company's management, with the participation of the Company's Chief
Executive Officer and Chief Financial Officer, has evaluated the effectiveness
of the Company's disclosure controls and procedures (as defined in Rules
13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended
(the "Exchange Act")), as of March 31, 2005. Based on their evaluation, the
Company's Chief Executive Officer and Chief Financial Officer concluded that the
Company's disclosure controls and procedures were effective as of March 31,
2005.

In conducting management's evaluation of the effectiveness of the Company's
internal control over financial reporting, the operations of Era, acquired on
December 31, 2004, were excluded. This business constituted $122.7 million and
$111.3 million of total and net assets, respectively, as of March 31, 2005 and
$26.2 million and $2.0 million of operating revenues and net loss, respectively,
for the three months ended March 31, 2005.

There has been no change in the Company's internal control over financial
reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act)
that occurred during the Company's fiscal quarter ended March 31, 2005, that has
materially affected, or is reasonably likely to materially affect, the Company's
internal control over financial reporting.
