The technical and functional specifications present 6 distinct modules but will be single-awarded to a single Holder per lot. Due to the challenge of technological evolution and ATB's needs during the term of the contract, some modules (see modules below) remain single-awarded but not exclusive during the term of the contract.

ATB thus reserves the right to solicit the Contract Holder on expressions of specific needs, but also other third parties during the life of the contract to readapt the module concerned to the need or target technologies.
