All sales of Spiros Products among DURA, its Affiliates and any of their sublicensees shall be disregarded for purposes of computing royalties under this Section 3, but in such instances royalties shall be payable only upon sales to unlicensed third parties unless such other sales were for purposes of end use, rather than for resale.
