English to Spanish Law/Patents Law: Contract(s)

Hola,

He visto varias opciones de traducción para el término "undertaking", pero no tengo muy claro cuál utilizar en este contexto. Se trata del apartado "varios" de un contrato, donde dice:

"Subject to the following sentence, references in this Agreement to a statutory provision shall be a reference to such statutory provision as it is in force on the date hereof. A reference to a statutory provision in (i) a representation shall be a reference to such statutory provision as it is in force on the date such representation is being made and (ii) an undertaking shall be a reference to such statutory provision as it is in force from time to time during the applicability of such undertaking."
