3.  WARRANTY

3.1.  The Operating Sub-Contractor warrants to the Authority that it has carried out and will continue to carry out all its obligations and duties under the Operating Sub-Contract in accordance with and to the standard required by the Operating Sub-Contract, provided always that the Operating Sub-Contractor has no liability hereunder which is greater or of a longer duration than that it owes to the Contractor under the Operating Sub-Contract.

3.2.  The Operating Sub-Contractor shall be entitled in any proceedings by the Authority to rely on any limitation in the Operating Sub-Contract and to raise equivalent rights in defence of liability (except for set off or counterclaim) as it would have against the Contractor under the Operating Sub-Contract.

3.3.  Notwithstanding anything in this Deed and not withstanding any payments which may be made by the Authority to the Operating Sub-Contractor, the Authority and the Operating Sub-Contractor will not be under any obligation to each other nor will any party have any claim or cause of action against the others unless and until the Authority has given written notice to the Operating Sub-Contractor pursuant to clause 7.1.1 or clause 7.3.
