12.1.4 Limitations of Warranty
(i) The Buyer's remedy and the Seller's obligation and liability under Clauses 12.1.1 and 12.1.2 are limited to, at the Seller's expense and option, **
(ii) If the Seller corrects a defect covered by Clause 12.1.1(iii) that becomes apparent within the Warranty Period, on the written request of the Buyer
the Seller will correct any such defect in any Aircraft that has not already been delivered to the Buyer. Subject to the provisions of Clause 8 to the
Agreement, the Seller will not be responsible for, nor deemed to be in default on account of, any delay in Delivery of any Aircraft or otherwise,
in respect of performance of this Agreement, due to the Seller's undertaking to make such correction. In the alternative, the Buyer and the Seller
may agree to deliver such Aircraft with subsequent correction of the defect by the Buyer at the Seller's expense, or the Buyer may elect to accept
Delivery and thereafter file a Warranty Claim as though the defect had become apparent immediately after Delivery of such Aircraft. **
(iii) If a defect that would otherwise be covered under this Clause 12 becomes apparent and the Buyer has complied with the requirements of Clause
12, and the Seller has no then available correction for the defect and the Seller believes the defect can reasonably be expected to affect all or a
substantial portion of the Aircraft, then the Buyer will be deemed to have given notice of such defect for all Aircraft that thereafter experience
such defect.
