Schedule & resource plan § 5 DCM to be produced over about two years Courtesy Y. Lecrecq § SMI 2 facility to be reorganized (layout) to fulfil production rate § During production, 3 operators 100 % with 75 % coordinator DCM Engineering Design Review – Prototyping and Production Plan 8

Infrastructure § Space reservation in Bldg. SMI 2 for the final assembly, QC and acceptance tests § For DCM: about 75 m 2 out of a total of 667 m 2 in SMI 2 as from Jan. 2022 § For Plugs: about 60 m 2 from now till mid of 2023 § Bldg. 189 will be used for proximity storage according to needs § Availability of Flex building needs to be checked DCM Engineering Design Review – Prototyping and Production Plan 9

Concluding remarks § § § § Today, the plan is based on a cable delivery in August 2021 It is assumed that the contributors, other than MSC-CMI, have sufficient resources to provide the services required. The needs of MSC-CMI in this respect are being put together, and the service providers will be approached to make sure they get prepared properly The qualification phase is expected to be completed in the beginning of Q 3 -2021 The prototype could be ready by end June 2022 The 5 th DCM could be ready by end February 2024. To achieve this, we assume that there is no interruption of the activities after completion of the prototype The resource profile for this project (part MSC-CMI) is almost flat over about 2 years The schedule needs to be integrated with the other activities within MSC-CMI. We do not expect major difficulties in relation to this integration The layout of SMI 2, and the associated needs in terms of storage, are being revised taking account of all the activities coming up in MSC-CMI in the coming years DCM Engineering Design Review – Prototyping and Production Plan 10
