Wheel specifically disclaims any right, title or interest (except as licensed hereunder) in the Box Technology, and Wheel shall not at any time claim that its use thereof pursuant to this Agreement has created in Wheel any right, title or interest (except as licensed hereunder) therein. Wheel waives and disclaims any title, right or interest (except as contemplated hereby) in the Box Technology which may arise under the law of any country from the permitted use of the Box Technology by Wheel hereunder. 2.3.

Wheel shall have the right to assign, sublicense, transfer or otherwise encumber the license and rights granted to Wheel hereunder without the prior written consent of Box; provided, however, that all assignments, sublicenses and transfers must be made in connection with or contemplation of sales or potential sales of rotors by Wheel. Wheel shall notify Box in writing upon any assignment, sublicense or transfer -5- of the Box Technology and shall provide Box with copies of any third party agreements relating thereto. 2.6. Wheel acknowledges that, subject to this Agreement, Box may license or grant rights in the Box Technology to any other person or entity. 2.7. The parties hereto agree that in the event that Wheel files any patent applications involving Technology relating to the Box Business (which is not used or useful in the Wheel Business) within the twelve-month period after the date hereof, they shall enter into a technology license agreement substantially similar to this agreement and pursuant to which Wheel shall grant to Box a fully paid, worldwide, nonexclusive, royalty free, perpetual license (including the right to sublicense) to any such Technology. 3. Patent Suits and Actions. 3.1. Each party to this Agreement shall promptly notify the other party of any material infringement of any Patent licensed hereunder and shall provide such other party with any available evidence of such infringement. Box at its cost shall have the right to bring, defend, direct and maintain any suit, action or proceeding involving infringement (an "Infringement Action") of any such Patent. Box shall give Wheel written -6- notice of its intention to commence any such Infringement Action and Wheel shall notify Box in writing (the "Participation Option") within ten (10) days of receiving Box's written notice as to whether Wheel wishes to participate in such Infringement Action. Regardless of Wheel's election in the Participation Option, if Box finds it necessary to be joined by Wheel in an Infringement Action, Wheel shall execute all papers and perform such other acts as may reasonably be required and may, at its option and cost, be represented by advisory counsel of its choice. Should Box lack standing to bring any Infringement Action, Wheel may agree to do so at the request and cost of Box upon an undertaking by Box to indemnify and hold Wheel harmless (to the extent permissible by law) from all consequent liability. 3.2. Wheel shall have the right, but not the obligation, to bring and maintain any appropriate Infringement Action in the event that Box declines to do so pursuant to paragraph 3.1 above. If Wheel finds it necessary to be joined by Box in such Infringement Action, Box shall execute all papers and perform such other acts as may be reasonably required and may, at its option and cost, be represented by advisory counsel of its choice. Should Wheel lack standing to bring any such Infringement -7- Action then Box shall do so at the request of Wheel upon an undertaking by Wheel to indemnify and hold Box harmless (to the extent permissible by law) from all consequent liability. 3.3. In any Infringement Action, the party bringing and maintaining such action shall pay all of the expenses (including attorneys' fees) incurred in connection with such action (other than any fees of advisory counsel as contemplated by Section 3.2 above). Any amount received in any such Infringement Action, whether by judgment or settlement, shall, after payment of all reasonable expenses incurred by the party bringing and maintaining such action, in connection with such Infringement Action, be paid to or retained by the party who brought and maintained such action. 3.4. It is expressly agreed that Box and Wheel shall each pay one-half of all Maintenance Costs related to the Box Technology licensed hereunder. The failure to pay its portion of Maintenance Costs related to any Box Technology licensed hereunder after 60 days written demand therefor, shall result in the forfeiture by Wheel of the license granted to it hereunder as to such Box Technology. Box shall keep Wheel apprised and give Wheel regular periodic reports with respect to all actions proposed to be taken by Box with respect to Maintenance Costs and related matters, including reasonable advance notice of -8- upcoming requirements for the payment of Maintenance Costs. Notwithstanding the foregoing, nothing in this Agreement shall prohibit (i) Box from discontinuing the payment of Maintenance Costs for any patent at any time or (ii) Wheel from electing to forfeit the right to license any or all Box Technology at any time. 4.
