2. LICENSEE hereby agrees that the licence granted in Clause 1 is subject to the following restrictions:
(i)
where a product created under Clause 1(i) is an integrated circuit which includes a CPU then either: (a) such CPU

(iii) no right is granted to LICENSEE to sublicense the rights granted to LICENSEE under this Agreement.
3.
Except as specifically licensed in accordance with Clause 1, LICENSEE acquires no right, title or interest in any Arm

WARRANTIES EXPRESS, IMPLIED OR STATUTORY, INCLUDING BUT NOT LIMITED TO ANY WARRANTY OF
