3 Executive Summary o Executive Summary o Reverse Costing Methodology o Glossary This full reverse costing study has been conducted to provide insight on technology data, manufacturing cost and selling price of the STMicroelectronics Proximity Sensor & Flood Illuminator in Apple iphone X. Located in the front above the main speaker, the proximity sensor & flood illuminator is packaged using optical LGA. The device is a custom version for Apple. In the past, STMicroelectronics has already release a custom proximity sensor two times smaller (2.80 x 2.40 mm) than the devices in it s portfolio. This new version came along with a flood illuminator used in the true depth system. The sensor is still based on FlighSense TM technology. In this report, the complete microsystem is analyzed from the two illumination device which are a Vertical-Cavity Surface-Emitting Laser (VCSEL) to the collector based on the Single Photon Avalanche Diode (SPAD) developed by STMicroelectronics. The report includes a complete cost analysis and price estimation of the device based on a detailed description of the package, the ToF detector, the VCSEL and the other VCSEL for the flood illumination. It also features a complete technology comparison with the STMicroelectronics ToF portfolio since the first generation, the VL53L0X the VL6180X, and the last custom proximity sensor from the Apple iphone by System Plus Consulting STMicroelectronics Proximity Sensor & Flood Illuminator 3

30 TERMS AND CONDITIONS OF SALES 1.INTRODUCTION The present terms and conditions apply to the offers, sales and deliveries of services managed by System Plus Consulting except in the case of a particular written agreement. Buyer must note that placing an order means an agreement without any restriction with these terms and conditions. 2.PRICES Prices of the purchased services are those which are in force on the date the order is placed. Prices are in Euros and worked out without taxes. Consequently, the taxes and possible added costs agreed when the order is placed will be charged on these initial prices. System Plus Consulting may change its prices whenever the company thinks it necessary. However, the company commits itself in invoicing at the prices in force on the date the order is placed. 3.REBATES and DISCOUNTS The quoted prices already include the rebates and discounts that System Plus Consulting could have granted according to the number of orders placed by the Buyer, or other specific conditions. No discount is granted in case of early payment. 4.TERMS OF PAYMENT System Plus Consulting delivered services are to be paid within 30 days end of month by bank transfer except in the case of a particular written agreement. If the payment does not reach System Plus Consulting on the deadline, the Buyer has to pay System Plus Consulting a penalty for late payment the amount of which is three times the legal interest rate. The legal interest rate is the current one on the delivery date. This penalty is worked out on the unpaid invoice amount, starting from the invoice deadline. This penalty is sent without previous notice. When payment terms are over 30 days end of month, the Buyer has to pay a deposit which amount is 10% of the total invoice amount when placing his order. 5. OWNERSHIP System Plus Consulting remains sole owner of the delivered services until total payment of the invoice. 6.DELIVERIES The delivery schedule on the purchase order is given for information only and cannot be strictly guaranteed. Consequently any reasonable delay in the delivery of services will not allow the buyer to claim for damages or to cancel the order. 7.ENTRUSTED GOODS SHIPMENT The transport costs and risks are fully born by the Buyer. Should the customer wish to ensure the goods against lost or damage on the base of their real value, he must imperatively point it out to System Plus Consulting when the shipment takes place. Without any specific requirement, insurance terms for the return of goods will be the carrier current ones (reimbursement based on good weight instead of the real value). 8.FORCE MAJEURE System Plus Consulting responsibility will not be involved in non execution or late delivery of one of its duties described in the current terms and conditions if these are the result of a force majeure case. Therefore, the force majeure includes all external event unpredictable and irresistible as defined by the article 1148 of the French Code Civil? 9.CONFIDENTIALITY As a rule, all information handed by customers to system Plus Consulting are considered as strictly confidential. A non-disclosure agreement can be signed on demand. 10.RESPONSABILITY LIMITATION The Buyer is responsible for the use and interpretations he makes of the reports delivered by System Plus Consulting. Consequently, System Plus Consulting responsibility can in no case be called into question for any direct or indirect damage, financial or otherwise, that may result from the use of the results of our analysis or results obtained using one of our costing tools. 11.APPLICABLE LAW Any dispute that may arise about the interpretation or execution of the current terms and conditions shall be resolved applying the French law. It the dispute cannot be settled out-of-court, the competent Court will be the Tribunal de Commerce de Nantes. Performed by
