1. Acknowledgments by Employee. Employee acknowledges that (a) during the Term, as that term is defined in the Agreement, and as a part of the Employment, Employee will be afforded access to Employer’s Confidential Information; (b) public disclosure of such Confidential Information could have an adverse effect on Employer and its business; (c) because Employee possesses substantial technical expertise and skill with respect to Employer’s business, Employer desires to obtain exclusive ownership of each Employee Invention, and Employer will be at a substantial competitive disadvantage if it fails to acquire exclusive ownership of each Employee Invention; and (d) the provisions of this Confidentiality Agreement are reasonable and necessary to prevent the improper use or disclosure of Confidential Information and to provide Employer with exclusive ownership of all Employee Inventions. For purposes of this Agreement, “Confidential Information” is defined as information which Employer reasonably considers to be confidential and proprietary to Employer.

2. Confidential and Trade Secret Information.

2.1. Employee acknowledges and agrees that all Confidential Information known or obtained by Employee, whether before or after the date of this Confidentiality Agreement, is the property of Employer. Therefore, Employee agrees that Employee shall hold in confidence the Confidential Information and shall not disclose it to any Person, including disclosures for the benefit of competitors of Employer, or use for personal gain any Confidential Information, whether Employee has such information in Employee’s memory or embodied in writing or other physical form, except with the specific prior written consent of Employer or except as otherwise expressly permitted by the terms of this Confidentiality Agreement or unless and to the extent that the Confidential Information is or becomes generally known to and available for use by the public other than as a result of Employee’s fault or the fault of any other person bound by a duty of confidentiality to Employer. Employee agrees to deliver or make available to Employer at any reasonable time Employer may request, all documents, memoranda, notes, plans, records, reports, and other documentation, models, components, devices, or computer software, whether embodied in a disk or in other form (and all copies of all of the foregoing), relating to the businesses, operations or affairs of Employer and any other Confidential Information that Employee may then possess or have under his control. Employee’s obligations under this Confidentiality Agreement are in addition to and cumulative with those he owes Employer under the Indiana Uniform Trade Secrets Act and any other applicable law.

2.2. Any trade secrets of Employer will be entitled to all of the protections and benefits under the Indiana Uniform Trade Secrets Act and any other applicable law.

2.3. None of the foregoing obligations and restrictions applies to any part of the Confidential Information that: (a) that Employee demonstrates was or became generally available to the public other than as a result of an improper disclosure by Employee; (b) Employee demonstrates was independently developed by Employee prior to receipt of the Confidential Information from Employer; (c) was approved for release by written authorization from Employer or (d) where disclosure was ordered by a court of competent jurisdiction.

2.4. Employee will not remove from Employer’s premises (except to the extent such removal is for purposes of the performance of Employee’s duties at home or while traveling, or except as otherwise specifically authorized by Employer) any document, record, notebook, plan, model, component, device or computer software or code, whether embodied in a disk or in any other form, (but not including devices, software or code owned by Employee and used by Employee in personal applications not involving Employer’s business), that relates in any way to, or is useful in any manner in, the business then being conducted or proposed to be conducted by Employer (collectively, the “Proprietary Items”). Employee recognizes that, as between Employer and Employee, all of the Proprietary Items, whether or not developed by Employee, are the exclusive property of Employer. Upon termination of the Agreement by either party, or upon the request of Employer during the Term, Employee will return to Employer all of the Proprietary Items in Employee’s possession or subject to Employee’s control, and Employee shall not retain any copies, abstracts, sketches or other physical embodiment of any of the Proprietary Items. Notwithstanding the foregoing, upon the reasonable request of Employee, Employer will permit Employee to obtain copies of specifically identified Proprietary Items that are necessary for Employee to respond to legal, tax or other regulatory proceedings.

3. Employee Inventions. For purposes of this Confidentiality Agreement, “Employee Inventions” shall be defined to include any discoveries, improvements, developments, tools, machines, apparatus, appliances, concepts, designs, computer software programs, promotional ideas, production processes or techniques, practices, formula methods and new products, useful in or related to the business in which Employer is engaged, whether patentable, copyrightable or otherwise, that are made, discovered, developed or secured by the Employee while employed by Employer and that pertain to the subject matter of Employee’s employment with Employer. Each such Employee Invention shall belong exclusively to Employer. Employee acknowledges that all of Employee’s Employee Inventions are works made for hire and the property of Employer including any copyrights, patents or other intellectual property rights pertaining thereto. Unless it is determined by a court of competent jurisdiction that any Employee Inventions were not made within the scope of the Employment, Employee hereby assigns to Employer all of Employee’s right, title, and interest, including all rights of copyright, patent, trademark and other intellectual property rights, to or in such Employee Inventions. Employee covenants that he will promptly:

3.1. disclose to Employer in writing any Employee Invention;

3.2. assign to Employer or to a party designated by Employer, at Employer’s request and without additional compensation, all of Employee’s right to the Employee Invention for the United States and all foreign jurisdictions;

3.4. sign all other papers necessary to carry out the above obligations; and

3.5. give testimony and render any other assistance in support of Employer’s rights to any Employee Invention.

4. Client Confidential Information. “Client Confidential Information” is information disclosed to Employee by a client or customer (“Client”) of Employer or other parties involved in a business arrangement between Employer and a Client, which at the time of disclosure is (a) designated by the Client as confidential; or (b) which by its nature or by the circumstances of its disclosure reasonably should be confidential; or (c) which is subject to a confidentiality agreement between Employer and the Client; or (d) because the information disclosed is not generally known by persons other than employees or representatives of Employer and the Client. Employee acknowledges and agrees that all Client Confidential Information known or obtained by Employee, whether before or after the date of this Agreement, is the property of the Client. Therefore, Employee agrees that, at any time during or after the Term, Employee shall hold in confidence the Client Confidential Information and shall not disclose it to any Person or use for his personal gain or for the benefit of any third party competitor of said Client any Client Confidential Information, whether Employee has such information in Employee’s memory or embodied in writing or other physical form, except (a) to the extent that the Client Confidential Information is or becomes generally known to and available for use by the public other than as a result of Employee’s fault or the fault of any other Person bound by a duty of confidentiality to the Client; (b) that the Client Confidential Information was independently developed by Employee prior to receipt of it from the Client; (c) with the specific prior written consent of an authorized representative of the Client or; (d) if the disclosure thereof was ordered by a court of competent jurisdiction. Employee agrees to deliver to Employer at any reasonable time Employer or the Client may request, all documents, memoranda, notes, plans, records, reports, and other documentation, models, components, devices, or computer software, whether embodied in a disk or in other form (and all copies of all of the foregoing), relating to the Client Confidential Information that Employee may then possess or have under his control.

Notwithstanding the foregoing, following the Term, Employee shall not be prohibited from engaging or investing in, owning, managing, operating, financing, controlling, or participating in the ownership, management, operation, financing, or control of, being employed by, associated with, or in any manner connected with, lending Employee’s name or any similar name to, lending Employee’s credit to or rendering services or advice to, any business whose products or activities do not compete with the above described services of Employer; nor shall Section 5.2(a) of this Confidentiality Agreement prevent Employee, following the Term, from acting in his individual capacity as a direct consultant (without employees or other professional assistance) for up to $500,000 per year of income, fees or other benefits to Employee, provided, however, that Employee must continue to comply with the remaining terms and conditions of this Confidentiality Agreement and Employee shall use his best efforts to recommend Employer for any work the Employee is not able to handle on his own;
