AMENDED AND RESTATED
THIS AGREEMENT dated as of 02/07/08 (the “Agreement Date”) is made by and among Tropical
Shipping and Construction Company Limited (the “Company” or “Tropical Shipping”), a Cayman Islands
company, and Rick Murrell (the “Executive”).
Executive and Birdsall, Inc., a Florida corporation (“Birdsall”), have previously entered into a Change-in-
Control Agreement dated December 15, 2004 (the “Prior Agreement”). Birdsall assigned its rights and
obligations with respect to the Prior Agreement to Tropical Shipping USA, LLC, a Florida limited liability
company (the “LLC”), and the LLC subsequently assigned its rights and obligations with respect to the Prior
Agreement to the Company. The Company and Executive desire to amend and restate the Prior Agreement to
conform to the requirements of Section 409A of the Code.
The Board has determined that it is in the best interests of the Company and its shareholders to assure
that the Company will have the continued services of the Executive, despite the possibility or occurrence of a
Change in Control of Nicor Inc. or the Company. The Board believes it is imperative to reduce the distraction of
the Executive that would result from the personal uncertainties caused by a pending or threatened Change in
Control, to encourage the Executive’s full attention and dedication to the Company, and to provide the Executive
with compensation and benefits arrangements upon a Change in Control which are competitive with those of
similarly situated corporations. This Agreement is intended to accomplish these objectives.
When used in this Agreement, the terms specified below shall have the following meanings:
The “Agreement Term” shall begin on the Agreement Date and shall continue through
December 31, 2008. As of December
