Helton and his attorneys, and United and its attorneys, agree and represent that they intend and believe that this Agreement is lawful and enforceable in its entirety. Helton and United agree that, to the extent any portion, provision, or covenant of this Agreement may be held to be invalid or legally unenforceable by an agency or court of competent jurisdiction, the remaining portions of this Agreement shall not be affected and shall be given full force and effect; provided, however, if any release, waiver, or agreement set forth in Paragraph 2 above or any portion of the covenant not to sue set forth in Paragraph 7 above is declared or alleged to be invalid illegal, or unenforceable in whole or in part through any action initiated by Helton, or if Helton initiates, conducts, encourages or participates in proceedings or litigation seeking relief or recovery for himself based on any of the released claims and causes of action, United's obligations under this Agreement shall be nullified and any payments or benefits that had been or were to be afforded to Helton under this Agreement shall be forfeited and immediately returned to United. 13. Injunction. Helton hereby expressly acknowledges that any breach or threatened breach by Helton of Paragraphs 4, 6 or 7 of this Agreement may result in significant and continuing injury and irreparable harm to United, the monetary value of which would be impossible to establish. Therefore, Helton agrees that United shall be entitled to injunctive relief in a court of appropriate jurisdiction with respect to such provisions. Attorneys' fees with respect to any action seeking injunctive relief shall be paid by Helton if such action is successful or by United if such action is - 9 - <Page> unsuccessful. The parties agree that this provision is a material inducement to entering into this Agreement. 14. Non-Admission. All parties agree and acknowledge that this Agreement does not constitute an admission by United of any liability or wrongdoing whatsoever, but results from the desire to expeditiously resolve disputed issues of fact and law, and further acknowledge that United denies all possible allegations of violations of any law, statute, ordinance, regulation, common law, tort or contract. United and Helton further agree that this Agreement shall not be admissible as evidence in any future proceeding of any kind, except one for breach of this Agreement. 15. Breach of Agreement. In the event that either party takes action, in law or equity, to assert a breach of this Agreement or to enforce its rights under any provision of this Agreement and it prevails, the other party shall be liable for the reasonable attorneys' fees and costs incurred by the non-breaching party in connection with such action. 16. Time to Review and Attorney Consultation. Helton acknowledges that he was encouraged to consult and did consult with an attorney before signing below and has been given at least twenty-one (21) days to review this Agreement.
