[TWO] years from the date of such delivery of such notice, this agreement shall cease and terminate, for reasons stated in Article Nine above, or if the patents have become of no value to the Licensee in view of other patents or other improvements in the [SPECIFY] industry, and become null and void; and any and all rights which the Licensee shall have or possess under this agreement shall be by it relinquished and surrendered to the Licensor; except that the Licensee shall have the right to sell all apparatus already manufactured, embodying the inventions, upon which royalties will be paid as provided for above.
