(c) Promptly after receipt by an indemnified party hereunder of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof, but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to such indemnified party other than under this Section 5(c) and shall only relieve it from any liability which it may have to such indemnified party under this Section 5(c) if and to the extent the indemnifying party is prejudiced by such omission.
