determined to pursue the previously announced spin-off (the
Spin-Off) of its offshore marine services business that is
conducted by its wholly-owned subsidiary, SEACOR Marine Holdings
Inc. (SEACOR Marine), by means of a distribution of all of the
outstanding shares of common stock of SEACOR Marine on a pro rata
basis to all of the holders of common stock of SEACOR.

of which is the number of shares of SEACOR Holdings common stock
outstanding on the Distribution Date; or approximately 1.007 shares

shares of SEACOR Holdings common stock outstanding as of the date
hereof.

the sole discretion of SEACOR without the approval of SEACOR Marine
or the stockholders of SEACOR.

Transition Services Agreements

SEACOR Marine and SEACOR entered into two separate transition
services agreements on an interim basis to help ensure an orderly
transition following the separation: (i) the SEACOR Transition
Services Agreement, to which SEACOR will provide SEACOR Marine with
a number of support services, including information systems
support, benefit plan management, cash disbursement support, cash
receipt processing and treasury management and (ii) the SEACOR
Marine Transition Services Agreement, to which SEACOR Marine will
provide SEACOR with general payroll services. In addition,
following the Spin-Off, SEACOR will provide SEACOR Marine and/or
SEACOR Marine will provide SEACOR with such other services as may
be agreed to by SEACOR Marine and SEACOR in writing from time to
time. Neither SEACOR Marine nor SEACOR will have any obligation to
provide additional services.

Under the SEACOR Transition Services Agreement, SEACOR will provide
SEACOR Marine with the services described above in a manner
historically provided to SEACOR Marine by SEACOR during the 12
months prior to the date of the agreement, and SEACOR Marine will
use the services for substantially the same purposes and in
substantially the same manner as SEACOR Marine used them during
such 12 month period. Under the SEACOR Marine Transition Services
Agreement, SEACOR Marine will provide SEACOR with general payroll
services in a manner historically provided by SEACOR to SEACOR
Marine during the 12 months prior to the date of the agreement, and
SEACOR will use the services for substantially the same purposes
and substantially the same manner as SEACOR Marine used them during
such 12 month period.

Amounts payable for services provided under the Transition Services
Agreements will be calculated on a fixed-fee basis, with each
Transition Services Agreement specifying an aggregate fixed fee for
all of the services described therein. SEACOR Marine expects to pay
SEACOR an aggregate monthly fee of $555,000 for the services
provided under the SEACOR Transition Services Agreement and SEACOR
Marine expects that SEACOR will pay SEACOR Marine an aggregate
monthly fee of $30,000 for the services provided under the SEACOR
Marine Transition Services Agreement.

Subject to limited exceptions, SEACOR Marine and SEACOR have each
agreed to limit SEACOR Marines respective liability to the other in
respect of causes of action arising under the Transition Services
Agreements. Under the SEACOR Transition Services Agreement, (i)
SEACOR Marine will indemnify SEACOR against third-party claims
stemming from SEACOR Marines (a) failure to fulfill confidentiality
obligations under such agreement and (b) infringement of the
intellectual property of any third party; provided that SEACOR
Marine will not be required to indemnify SEACOR for losses
resulting from SEACORs willful misconduct, bad faith or gross
negligence and (ii) SEACOR will indemnify SEACOR Marine against
third-party claims stemming from SEACORs (a) failure to fulfill its
obligations as set forth in such agreement and (b) infringement of
the intellectual property of any third party; provided that SEACOR
will not be required to indemnify SEACOR Marine for losses
resulting from SEACOR Marines willful misconduct, bad faith or
gross negligence. Under the SEACOR Marine Transition Services
Agreement, (A) SEACOR will indemnify SEACOR Marine against
third-party claims stemming from SEACORs (x) failure to fulfill
confidentiality obligations under such agreement and (y)
infringement of the intellectual property of any third party;
provided that SEACOR will not be required to indemnify SEACOR
Marine for losses resulting from SEACOR Marines

willful misconduct, bad faith or gross negligence and (B) SEACOR
Marine will indemnify SEACOR against third-party claims stemming
from SEACOR Marines (x) failure to fulfill SEACOR Marines
obligations as set forth in such agreement and (y) infringement of
the intellectual property of any third party; provided that SEACOR
Marine will not be required to indemnify SEACOR for losses
resulting from its willful misconduct, bad faith or gross
negligence.

to the Transition Services Agreements, SEACOR Marine and SEACOR
have each agreed to customary confidentiality agreements regarding
any confidential information of the other party received in the
course of performance of the services.

SEACOR Marine will also be responsible for its own
transition-related costs and expenses (e.g., to procure its own IT
infrastructure) and certain costs and expenses incurred by SEACOR
to transfer software licenses to SEACOR Marine, including (i)
transfer fees charged by third-party software licensors and (ii)
unamortized SEACOR costs and expenses to procure and deploy the
software being transferred to SEACOR Marine.

Each Transition Services Agreement will continue in effect for up
to two years. In the event that SEACOR Marine defaults under the
SEACOR Transition Services Agreement or SEACOR defaults under the
SEACOR Marine Transition Services Agreement, the non-breaching
party may, in addition or as an alternative to terminating the
respective agreement, declare immediately due and payable all sums
which are payable under such agreement or suspend such agreement
and decline to continue to perform any of the obligations
thereunder.

In the event functions provided under a Transition Services
Agreement are outsourced by the provider, the provider of the
services under the Transition Services Agreement will have the
option, but not the obligation, to also transition the recipient,
along with the provider, to the new outsourced solution. If the
provider decides not to transition to the recipient to the new
outsourced solution, the provider may opt to stop providing these
outsourced services upon 90 days notice.

Employee Matters Agreement

The Employee Matters Agreement allocates liabilities and
responsibilities between SEACOR Marine and SEACOR relating to
employee compensation and benefit plans and programs, including the
treatment of retirement and health plans, equity incentive and
compensation programs. In general, the Employee Matters Agreement
provides that, following the distribution, SEACOR Marines employees
will participate in SEACOR Marines incentive, health and benefit
plans and will cease to participate in SEACORs incentive, health
and benefit plans (other than with respect to awards previously
granted under SEACORs equity incentive plans). In general, SEACOR
Marine will be responsible for the employment and benefit-related
obligations and liabilities of its employees following the
Spin-Off.

Under the Employee Matters Agreement, all outstanding stock options
to purchase shares of SEACOR common stock (SEACOR Options) will be
adjusted to reflect the difference in value prior to the Spin-Off
of SEACORs common stock on the regular way market and
ex-distribution market for such stock and to preserve the aggregate
intrinsic value of such stock options. Accordingly, the exercise
price and number of shares of SEACOR common stock subject to such
SEACOR Options will be adjusted. The terms and conditions
applicable to such SEACOR Options will otherwise remain the same,
except that the vesting of any unvested SEACOR Options held by
SEACOR Marine employees will be accelerated, and such individuals
will have 90 days to exercise their SEACOR Options. SEACOR Options
held by Messrs. Morse, Regan and Behrens will remain exercisable
for the remainder of the original terms of their respective SEACOR
Options.

Individuals who hold restricted shares of SEACOR common stock
(SEACOR Restricted Stock) as of the Record Date will receive the
Spin-Off dividend. The restrictions applicable to SEACOR Restricted
Stock held by SEACOR Marine employees will lapse, but the Spin-Off
dividend received by such individuals will be subject to the same
restrictions and vesting conditions originally applicable to the
underlying shares of SEACOR Restricted Stock.

Tax Matters Agreement

The Tax Matters Agreement governs the parties respective rights,
responsibilities and obligations with respect to taxes, tax
attributes, the preparation and filing of tax returns, the control
of audits and other tax proceedings and assistance and cooperation
in respect of tax matters with respect to U.S. federal income taxes
for periods during which SEACOR Marine was part of SEACORs
consolidated tax group, after taking into account any tax sharing
payments that have already been made, (i) SEACOR shall compensate
SEACOR Marine, or alternatively, SEACOR Marine

shall compensate SEACOR, for use of any net operating losses, net
capital losses or foreign tax credits generated by the operations
of the other party as calculated on a separate company basis and
utilized in the consolidated tax return and (ii) SEACOR Marine
shall compensate SEACOR for any taxable income attributable to
SEACOR Marines operations. Taxes relating to or arising out of the
failure of the separation to qualify as a tax-free transaction for
U.S. federal income tax purposes will be borne by SEACOR, except,
in general, if such failure is attributable to SEACOR Marines
action or inaction or SEACORs action or inaction, as the case may
be, or any event (or series of events) involving SEACOR Marines
assets or stock or the assets or stock of SEACOR, as the case may
be, in which case the resulting liability will be borne in full by
SEACOR Marine or SEACOR, respectively.

The summary of each of the Distribution Agreement, SEACOR
Transition Services Agreement, SEACOR Marine Transition Services
Agreement, Employee Matters Agreement and Tax Matters Agreement is
qualified in its entirety by reference to the complete terms and
conditions of each such agreement, each of which is incorporated
