                     Re:  SEACOR SMIT Inc.
                          ----------------

Dear Dr. Carter:

                     In connection with the 2003 Annual Meeting of Stockholders
of SEACOR SMIT Inc. (the "Company"), scheduled to occur on May 14, 2003 (the
"SEACOR Annual Meeting"), the Board of Directors of the Company (the "Board")
has proposed adoption of the SEACOR SMIT Inc. 2003 Share Incentive Plan (the
"Plan"). Institutional Shareholder Services, in its Proxy Analysis of matters to
be voted upon at the SEACOR Annual Meeting has recommended, among other things,
that SEACOR stockholders vote against adoption of the Plan because the Plan
contains, in Section 22 thereof ("Section 22"), language expressly permitting
option repricing. For your convenience, Section 22 is attached hereto as Annex
A.

This letter is to confirm that:

           1. Without the prior approval of the Company's stockholders, options
issued under the Plan will not be repriced, replaced, or regranted through
cancellation, or by lowering the option exercise price of a previously granted
award, and that,

           2. The Plan will be submitted to the SEACOR Board of Directors for
amendment at its next meeting to reflect this clarification and a copy of the
plan as so amended will be sent to ISS.

                     In connection with these undertakings on my part, please
accept my request that ISS amend its Proxy Analysis to recommend approval by
stockholders of the Plan.
