Clause 5.7 of the Main Contract is amended as follows: 5.7 Unless the Purchaser shall otherwise agree the Builder shall supply those items of Materials set out in Appendix IIA (the Listed Items) from suppliers and subcontractors nominated by the Purchaser. The Purchaser, as agent for and on behalf of the Builder, shall negotiate terms and expedite equipment with each of the Nominated Subcontractors in order to supply the Listed Items set out in Appendix IIA.

In the event of any variations in the actual price then the Listed Items Price shall be increased or decreased by an amount equal to the amount of such variations. Any such variations shall be payable by the Purchaser by means of an adjustment of the final instalments of the Construction Price." 2.5 Clause 5.9 of the Main Contract is amended as follows: 5.9 Furthermore, in the event that delivery to the Builder of any Listed Item is delayed beyond the Target Delivery Date for the same set out in Appendix IIA, the Builder shall be entitled to a postponement of the Contractual Delivery Date for a period as it shall demonstrate, by reference to the "critical path" that the Vessel's construction and completion has actually been delayed. Delays in delivery of more than one Listed Item occurring simultaneously, shall have given rise only to concurrent (rather than consecutive) extensions. Any verified and documented delays caused, or contributed to by the Builder taking more than 14 days, after receipt, to pay approved Nominated Subcontractors invoices that have been submitted by the Purchaser in the agreed format will become cause for an adjustment in the delivery date of the Listed Items as detailed in Appendix IIA. Such adjustments shall reflect the ultimate delay in the arrival of the Listed Item at the Builder's yard. 3.
