7. Enforcement and Remedies.

(a) If, at the time of enforcement of any of Sections 6(a),(b), (c) or (d), a court of competent jurisdiction shall hold that the restrictions stated herein are unreasonable under circumstances then existing, the parties hereto agree that the court shall be allowed to substitute the maximum legally-permissible restrictions for the restrictions contained in this Agreement.

Agreement and has given careful consideration to the restraints imposed upon Xykis by this Agreement and is in full accord as to their necessity.

Therefore, in the event of a breach or threatened breach of any such provision, the Company and/or any Company Affiliate or their respective successors or assigns shall be entitled to, in addition to other rights and remedies existing in their favor, apply to any court of competent jurisdiction for specific performance and/or injunctive or other relief in order to enforce or prevent any violations of the provisions hereof (without the necessity of posting a bond or other security, or proving economic harm).
