Artikel 2

The Contracting Officer may at any time, by a written notice make changes, within the general scope, of this contract, in any one or more of the following:
(i) Drawings, designs, or specifications, where the supplies to be furnished are to be specially manufactured for the United States Government in accordance therewith;
(ii) Method of shipment or packing; and
(iii) Place of delivery.
If any such change causes an increase or decrease in the cost of, or the time required for, performance of this contract an equitable adjustment shall be made in the contract price or delivery schedule, or both, and the contract shall be modified in writing accordingly. Any claim by the Netherlands Government for adjustment under this clause must be declared within thirty days from the date of receipt by the Netherlands Government of the notification of change; provided, however, that the Contracting Officer if he decides that the facts justify such action, may receive and act upon any such claim asserted at any time prior to final payment under this contract.
The Netherlands Government will proceed with the contract as changed and the United States Government will process claims as promptly as possible.
