threatened by or against any Operating Company law

[MARIAAM]

Поскажите, пожалуйста, как лучше перевести в следующем абзаце " by and against " и "which do not have and are not likely to have "

So far as the Warrantor is aware, there are no such proceedings pending or threatened by or against any Operating Company, except in either case litigation, arbitration or other proceedings which do not have, and are not likely to have a Material Adverse Effect.
