If the Company terminates Executive’s employment for Cause, Executive shall be paid his salary and benefits through the date of termination and, except as otherwise required by applicable law or under any applicable and properly approved compensation plan or arrangement, no other amounts shall be payable.

Notwithstanding Section 7.2(b), the Company reserves the right in any future special award to override Section 7.2(b) with respect to such special award; provided however, no such override is intended by this provision with respect to annual awards. As used in this Agreement, “Good Reason” shall mean any of the following if the same occurs without Executive’s express written consent: (a) a material diminution in Executive’s base salary as described in Section 4.1, which for such purposes shall be deemed to exist with a reduction of greater than fifteen percent (15%); (b) a material diminution in Executive’s authority, Duties, or responsibilities; (c) a material diminution in the authority, duties, or responsibilities of the person to whom Executive is required to report; (d) a material change in the geographic location (defined as greater than fifty (50) miles from Omaha, NE) at which Executive must perform the services pursuant to Section 1; (e) any material reduction or other material adverse change in Executive’s benefits under any applicable and properly approved compensation plan or arrangement without the substitution of comparable benefits; or (e) any other action or inaction that constitutes a material breach by the Company under this Agreement.

Executive acknowledges that, upon termination of his employment, he is entitled to no other compensation, severance or other benefits other than those specifically set forth in this Agreement, except to the extent provided in any applicable compensation plan or arrangement.

8.Covenant Not to Compete; Nonsolicitation.

8.2Non-Solicitation of Employees. Executive agrees that, during the term of Executive’s employment with Company and for a period of two (2) years after termination of Executive’s employment with Company (voluntary or involuntary, for Good Reason, any reason or no reason), Executive will not, directly or indirectly, recruit, solicit, or induce, or attempt to induce, any employee(s) of Company, sales representatives, or foreign agents with or through whom Company conducts business (and with whom Executive worked and had personal contact during Executive’s employment) to terminate their employment with, or otherwise cease a relationship with, Company.

8.4Reasonable Restrictions. In signing this Agreement, Executive is fully aware of the restrictions that this Agreement places upon Executive’s future employment or contractual opportunities with someone other than Company. However, Executive understands and agrees that Executive’s employment by Company and Executive’s access to Confidential Information (as defined below), trade secrets and goodwill of Company makes such restrictions both necessary and reasonable. Executive acknowledges and agrees that the restrictions hereby imposed constitute reasonable protections of the legitimate business interests of Company and that they will not unduly restrict Executive’s opportunity to earn a reasonable living following Executive’s termination from employment with Company.

8.5Intended Third Party Beneficiaries. Executive acknowledges and understands that some of the Confidential Information, trade secrets and/or goodwill accessible to Executive in the performance of Executive’s duties during Executive’s employment with Company may belong to and be provided by Company’s parents, subsidiaries, and/or affiliates (“Third Party Beneficiaries”). For purposes of this Agreement, the term “affiliates” means any entity under common control or ownership with Company. Executive expressly acknowledges and agrees that the Third Party Beneficiaries are intended third party beneficiaries of this Agreement as it pertains to Executive’s obligations under this Agreement and shall have the right to enforce this Agreement directly against Executive in their own names or jointly with Company or each other. This Agreement, without more, is not intended to and shall not be construed as granting any Third Party Beneficiary with any ownership interest of any kind in any of Company’s Confidential Information.

9.Confidential Information. Executive acknowledges that during his employment or consultancy with the Company he will develop, discover, have access to and/or become acquainted with technical, financial, marketing, personnel and other information relating to the present or contemplated products or the conduct of business of the Company which is of a confidential and proprietary nature (“Confidential Information”).

Executive further agrees not to disclose or use any Confidential Information and to use his best efforts to prevent the disclosure or use of any Confidential Information either during the term of his employment or consultancy or at any time thereafter, except as may be necessary in the ordinary course of performing his duties under this Agreement. Upon termination of Executive’s employment or consultancy with the Company for any reason, (a) Executive shall promptly deliver to the Company all materials, documents, data, equipment and other physical property of any nature containing or pertaining to any Confidential Information, and (b) Executive shall not take from the Company’s premises any such material or equipment or any reproduction thereof.

Furthermore, Executive agrees to assist the Company in every proper way at the Company’s expense to obtain patents, copyrights and other statutory or common law protections for such Employment Inventions in any country and to enforce such rights from time to time. Specifically, Executive agrees to execute all documents as the Company may desire for use in applying for and in obtaining or enforcing such patents, copyrights and other statutory or common law protections together with any assignments thereof to the Company or to any person designated by the Company. Executive’s obligations under this Section 10 shall continue beyond the termination of his employment under this Agreement, but the Company shall compensate Executive at a reasonable rate after any such termination for the time which Executive actually spends at the Company’s request in rendering such assistance. In the event the Company is unable for any reason whatsoever to secure Executive’s signature (after reasonable attempts to do so) to any lawful document required to apply for or to enforce any patent, copyright or other statutory or common law protections for such Employment Inventions, Executive hereby irrevocably designates and appoints the Company and its duly authorized officers and agents as his agents and attorneys-in-fact to act in his stead to execute such documents and to do such other lawful and necessary acts to further the issuance and prosecution of such patents, copyrights or other statutory or common law protection, such documents or such acts to have the same legal force and effect as if such documents were executed by or such acts were done by Executive.

If no inventions are listed on Exhibit A, Executive represents that he has made no such inventions at the time of signing this Agreement.

10.5Inventions of Third Parties. Executive shall not disclose to the Company, use in the course of his employment, or incorporate into the Company’s products or processes any confidential or proprietary information or inventions that belong to a third party, unless the Company has received authorization from such third party and Executive has been directed by the CEO to do so.
