An Indemnified Party’s failure to so notify the Indemnifying Party shall not, however, relieve such Indemnifying Party from any liability under this Agreement to the Indemnified Party with respect to such claim except to the extent that such Indemnifying Party is actually denied, during the period of delay in notice, the opportunity to remedy or otherwise mitigate the event or activity(ies) giving rise to the claim for indemnification and thereby suffers or otherwise incurs additional Losses as a result of such failure.
