Upon termination pursuant to Section 3.1 (b), the Executive shall be entitled to receive all compensation and benefits provided in Sections 2.1 through 2.3, for the first one hundred and eighty (180) days of his disability.

Such payments and benefits shall be in full satisfaction of all claims by Executive against the Company, and the Company shall not provide Executive with any other compensation or benefits described in Section 2.

4. Covenant Against Unfair Competition.

4.1 Executive agrees that for a period (the “Restricted Period”) starting on the date hereof and ending one (1) year following the termination of his/her employment for any reason, he/she will not, for his/her own account or jointly with another, directly or indirectly, for or on behalf of any individual, partnership, corporation, or other legal entity, as principal, agent or otherwise:

(a) own, control, manage be employed by, consult with, or otherwise participate in, a business (other than that of the Company) involved within the Trade Area (as hereinafter defined) with any of the following activities (the “Business”): (1) the storage, handling, delivery, marketing, sale, distribution or brokerage of aviation fuel, marine fuel or lubricants, aviation flight services, or marine fuel services, or (2) any other service or activity which is competitive with the services or activities which are or have been performed by the Company or its subsidiaries or affiliates since January 1, 1998;

(b) solicit or induce, or in any manner attempt to solicit, any person employed by the Company or any of its subsidiaries or affiliates to leave such employment, whether or not such employment is pursuant to a written contract and whether or not such employment is at will, or hire any person who has been employed by the Company or any of its subsidiaries or affiliates at any time during the one (1) year period preceding such hiring; or

-3-

(c) use or disclose any trade secrets or confidential information concerning the Business or any segment thereof. Trade secrets and confidential information concerning the Business shall include, but not be limited to: (1) lists of names and addresses of customers and suppliers of the Company or any of its subsidiaries or affiliates, and (2) software and computer programs, market research and data bases, sources of leads and methods of obtaining new business, and methods of purchasing, marketing, selling, performing and pricing products and services employed by the Company or any of its subsidiaries or affiliates in the Business or any segment thereof.

4.2 As used herein, the term “Trade Area” shall mean the United States of America, and any other foreign countries or regions, which are regularly serviced by the Company during the Employment Term, which areas define the territory in which the Company conducts or has conducted the majority of its business and solicits the majority of its patronage.

4.3 Executive recognizes the importance of the covenant contained in this Section 4 and acknowledges that, based on his/her past experience and training as an Executive of the Company and the projected expansion of the Company’s business, the restrictions imposed herein are: (i) reasonable as to scope, time and area; (ii) necessary for the protection of the Company’s legitimate business interests, including without limitation, the Company’s trade secrets, goodwill, and its relationship with customers and suppliers; and (iii) not unduly restrictive of any of Executive’s rights as an individual. Executive acknowledges and agrees that the covenants contained in this Section 4 are essential elements of this Agreement and that but for these covenants, the Company would not have entered into this Agreement. Such covenants shall be construed as agreements independent of any other provision of this Agreement. The existence of any claim or cause of action against the Company by Executive, whether predicated on the breach of this Agreement or otherwise, shall not constitute a defense to the enforcement by the Company of the covenants contained in this Section 4.

4.4 If Executive commits a breach or threatens to commit a breach of any of the provisions of this Section 4, the Company shall have the right and remedy, in addition to any others that may be available, at law or in equity, to have the provisions of this Section 4 specifically enforced by any court having equity jurisdiction, through injunctive or other relief (without any bond or security being required to be posted), it being acknowledged that any such breach or threatened breach will cause irreparable injury to the Company, the amount of which will be difficult to determine, and that money damages will not provide an adequate remedy to the Company.

4.5 If any covenant contained in this Section 4, or any part thereof, is hereafter construed to be invalid or unenforceable, the same shall not affect the remainder of the covenants, which shall be given full effect, without regard to the invalid portions, and any court having jurisdiction shall have the power to reduce the duration, scope and/or area of such covenant and, in its reduced form, said covenant shall then be enforceable. If Executive breaches the covenants set forth in this Section 4, the running of the non-compete period described herein (but not his/her obligation) shall be tolled for so long as such breach continues.

4.6 The provisions of this Section 4 shall survive the expiration and termination of this Agreement, and the termination of Executive’s employment hereunder for any

-4-

reason. If after termination of this Agreement, or the initial Employment Term (or any renewal thereof), the Executive remains employed by the Company, as an at-will employee, consultant or on any other full or part-time basis, then notwithstanding anything to the contrary set forth herein, the Restricted Period shall not commence to run until the last day Executive is employed by or is providing services to the Company, even though this Agreement or the Employment Term may have terminated at an earlier date.

5. Related Party Transactions. So long as Executive is employed by the Company, he shall not, without the prior written consent of the Company, cause or permit the Company or any of its subsidiaries or affiliates to enter into or effect any agreement or transaction, or provide or receive any service, between the Company on the one hand, and Executive or a Related Party, on the other hand, except for the employment relationship contemplated hereby. In any event, any such agreements, transactions or services shall be at prices and terms which are not less favorable to the Company than the prices and terms available for similar agreements, transactions or services with unrelated third parties.

6. Company Property.

(a) The Company shall be the sole owner of all products and proceeds of the Executive’s services hereunder, including, but not limited to, all materials, ideas, concepts, formats, suggestions, developments, arrangements, packages, programs and other intellectual properties that the Executive may acquire, obtain, develop or create in connection with and during the term of the Executive’s employment hereunder, free and clear of any claims by the Executive (or anyone claiming under the Executive) of any kind or character whatsoever (other than the Executive’s right to receive compensation hereunder). The Executive shall, at the request of the Company, execute such assignments, certificates or other instruments as the Company may from time to time deem necessary or desirable to evidence, establish, maintain, perfect, protect, enforce or defend its right, title and interest in or to any such properties. Upon the termination of the Executive’s employment for any reason whatsoever, all documents, records, notebooks, equipment, price lists, specifications, programs, customer and prospective customer lists and other materials which refer or relate to any aspect of the Business which are in the possession of the Executive (including all copies thereof), shall be promptly returned to the Company.

(b) The Executive agrees that all processes, technologies and inventions (“Inventions”), including new contributions, improvements, ideas and discoveries, whether patentable or not, conceived, developed, invented or made by him during his employment by the Company shall belong to the Company, provided that such Inventions grew out of the Executive’s work with the Company, are related in any manner to the Business or are conceived or made on the Company’s time or with the use of the Company’s facilities or materials. The Executive shall (i) promptly disclose such Inventions to the Company; (ii) assign to the Company, without additional compensation, all patent and other rights to such Inventions for the United States and foreign countries; (iii) sign all papers necessary to carry out the foregoing; and (iv) give testimony in support of his inventorship.

This Agreement may be modified or amended only by a writing signed by both parties hereto.

7.2 Governing Law/Arbitration. The validity and effect of this Agreement shall be governed by and construed and enforced in accordance with the laws of the State of Florida, without regard to any conflict-of-law rule or principle that would give effect to the laws of another jurisdiction.

The arbitration shall be conducted in accordance with the employment dispute arbitration rules of the American Arbitration Association. Each of the parties hereby irrevocably submits to the jurisdiction of the arbitrator(s) in an arbitration proceeding held in Miami-Dade County, Florida.
