18. Ownership of Intellectual Property. Any and all inventions, discoveries, improvements, or creations (“Intellectual Property”) that Employee has conceived or made or may conceive or make during the period of employment that in any way, directly or indirectly, are connected with or related to the Company or OCC, and/or their businesses, shall be the sole and exclusive property of the Company and/or OCC.

Employee further agrees to execute any and all additional powers of attorney, declarations, or other documents that may be necessary to accomplish the foregoing.

19. Court’s Right To Modify Restrictions. The parties have attempted to limit Employee’s right to compete only to the extent necessary to protect the Company in its legitimate business interests and from unfair competition. If the scope or enforceability of this Agreement is in any way disputed at any time, the Company and Employee agree that a court or other trier of fact may modify and enforce the Agreement to the extent it believes to be reasonable under the circumstances.

20. Enforcement. Employee acknowledges that, in the event of a breach or threatened breach of any of the covenants and promises contained herein, the Company will suffer irreparable injury for which there is no adequate remedy at law. Employee therefore agrees that the Company will be entitled to both preliminary and permanent injunctive relief from the courts enjoining any such breach or threatened breach without the necessity of posting a bond to secure injunctive relief. The Company shall have the right to seek a remedy at law as well as, or in lieu of, equitable relief in the event of any such breach. If it is determined that Employee has violated any of his or her obligations under Section 15, 16, or 17 of this Agreement, then the period applicable to each obligation that Employee has been determined to have violated automatically will be extended by a period of time equal in length to the period during which such violation(s) occurred. If a court concludes that Employee has breached this Agreement, in addition to all other remedies available at law or in equity, Employee shall pay all of the Company’s costs and expenses resulting therefrom and/or incurred in enforcing this Agreement, including attorneys’ fees.

21. Severability. If any provision in this Agreement is determined to be in violation of any law, rule or regulation or otherwise unenforceable, such determination will not affect the validity of any other provision of this Agreement, which will remain in full force and effect. Each section, provision, paragraph and subparagraph of this Agreement is severable from every other section, provision, paragraph and subparagraph and constitutes a separate and distinct covenant.

22. Governing Law; Venue. The parties agree that this Agreement is entered into in the State of North Carolina and that the rights and obligations of all parties to this Agreement shall be governed by the laws of North Carolina, without regard to its choice of law provisions. Employee agrees that the exclusive venue for any lawsuit, whether for an injunction, specific performance, damages or other relief, shall be any federal court in the Western District of North Carolina, or Buncombe County Superior Court, and Employee waives any objections to jurisdiction and venue which Employee otherwise may have as to any such lawsuit.
