ARTICLE 3

MISCELLANEOUS

3.01. Specific Performance. The parties agree that a breach or threatened breach of the covenants or restrictions contained in this Agreement would cause irreparable harm to the Company, and that a remedy at law for any breach or threatened breach would be inadequate and would be difficult to ascertain. Therefore, in the event of a breach or threatened breach of any of the covenants or restrictions contained in this Agreement, the Company shall have the independent right to enjoin any Shareholder from any threatened or actual activities in breach of this Agreement. No Shareholder will assert as a defense that the harm to the Company is not irreparable or that money damages are an adequate remedy. The existence of any claim or cause of action of any Shareholder against the Company, whether predicated on this Agreement or otherwise, will not constitute a defense to the enforcement of the covenants and restrictions described in this Agreement. The parties agree that the provisions of this Section shall be construed as an independent agreement of any other provision of this Agreement. The remedy provided in this Section shall be in addition to any other remedies available to the Company at law, in equity or otherwise.

3.03. Amendments; No Waivers. Any provision of this Agreement may be amended or waived if, and only if, such amendment or waiver is in writing and signed by Shareholders and the Company. No failure or delay by any party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by law.

3.04. Benefit; Successors and Assigns; No Third Party Beneficiaries. This Agreement is for the benefit of, and may be enforced by, the Company. The provisions of this Agreement shall be binding upon the Shareholders hereto and their respective successors and assigns; provided that, none of the Shareholders may assign, delegate or otherwise transfer any of its rights or obligations under this Agreement without the written consent of the Company. Neither this Agreement nor any provision hereof is intended to confer upon any Person other than the parties hereto and the Company any rights or remedies hereunder.

3.05. Counterparts. This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

3.06. Entire Agreement.

No representation, inducement, promise, understanding, condition or warranty not set forth herein has been made or relied upon by any of the parties hereto.

3.07. Governing Law. This Agreement shall be construed in accordance with and governed by the laws of the State of Delaware, without regard to the conflicts of law rules of such state.
