1.4 Any major or minor changes to the present production conditions (change of raw materials, production plant, main process parameters, manufacturing process, product/process controls and control limits, packaging, etc.) which may modify the characteristics of the finished product, including visual attributes, chemical analyses, dimensional measurements, physical and/or functional characteristics, shall be communicated in advance to SunEdison Semiconductor for review, qualification (as needed) and approval. In the event that SunEdison Semiconductor needs its customer approval to accept a change varying timeframes of longer durations than referenced may be required depending on SunEdison Semiconductor’s customers’ requirements. Exceptions to the referenced notification timeframe would include abnormal shutdowns of a line or facility, which would be reported to SunEdison Semiconductor immediately after the occurrence. Critcial suppliers are required to provide an annual change horizon forecast to allow sufficient time for review and discussion. This clause shall be referenced to SunEdison Semiconductor Corporate Procedure WWQS062 (Supplier Product and Process Qualification and Change Notification Procedure) which states the specific notification time requirements and is provided for reference.
