All Know-how and technical information in the possession of the Inventor which may reasonably be relevant to the design, manufacture, marketing, and use of the Technology shall be deemed to be confidential information. The Inventor shall not disclose or authorize the disclosure of such information to any third party, except as expressly permitted by Skyflyer in writing. The Inventor shall take reasonable precautions to prevent the unauthorised disclosure to third parties of all such confidential information.

If an order is made or a resolution is passed or a petition is filed for the final liquidation or winding-up of the Borrower; or

If final bankruptcy proceedings are commenced by or against Skyflyer or if Skyflyer makes a general assignment for the benefit of its creditors or otherwise acknowledges its insolvency.

Upon the occurrence of an Event of Default, and at any time thereafter, provided that Skyflyer has not by then remedied such Event of Default, the Inventor shall have the right to demand that all right, title and interest to the Technology be transferred back to the Inventor (a “Reversion Demand”). Upon the receipt of a Reversion Demand delivered in accordance with this Section 12, Skyflyer shall transfer all right, title and interest to the Technology to the Inventor and shall assist the Inventor in every legal way to evidence, record and perfect the transfer and assignment of the Technology to the Inventor and to apply for and obtain recordation of, and from time to time enforce, maintain and defend, the assigned rights embodied in the Technology on behalf of the Inventor.
