English to Czech Bus/Financial Law: Taxation & Customs záruka odškodnění

Na první pohled poněkud nesrozumitelná (za slovem whether) věta v záruce odškodnění přepravce (a chybí v ní člen a pomlčky u 2 slov):

We hereby undertake to indemnify and to pay to you the amount of any of such duties, taxes, import levies, deposits (....) by you or claimed from you by H. M. Revenue & Customs at any time in respect of such goods and whether or not we have right of deduction, set off or counter claim of any cause of action whatsoever against you.
