Specific Performance.  The Executive acknowledges and agrees that the Company's remedies at law for a breach of any of the provisions of Paragraph 3 would be inadequate.  In recognition of this fact, the Executive agrees that, in the event of such a breach, in addition to any remedies at law, the Company, without posting any bond, shall be entitled to bring an action in any court of competent jurisdiction for the purpose of obtaining equitable relief in the form of specific performance or any other equitable remedy which may then be available.
