English to Polish Tech/Engineering Telecom(munications)

A failure by XYZ to perform its dependencies will not give rise to a right of the Supplier to terminate or to claim damages, but may excuse the Supplier from non-performance to the extent this is caused by XYZ not performing its dependencies.

Wiem, co to są dependencies, ale zastanawiam się czy nie chodzi tu przypadkiem o niewykonanie obowiązków?

Pozdrawiam i z góry dziękuję za wszelkie sugestie.
