PRIOR INVENTIONS. It is understood that all Inventions, if any, patented or unpatented, which are made by me prior to my employment by the Company, are excluded from the scope of this Agreement. To preclude any possible uncertainty, I have set forth on Exhibit A attached to this Agreement a complete list of all my prior Inventions, including those which are the property of a previous employer. I represent and covenant that the list is complete and that, if no items are on the list, I have no such prior Inventions. I agree to notify the Company in writing before I make any disclosure or perform any work on behalf of the Company which appears to threaten or conflict with proprietary rights I claim in any Invention or idea. In the event of my
failure to give such notice, I agree that I will make no claim against the Company with respect to such Inventions or ideas.
