The omission of such indemnified party to so notify the indemnifying party of any such action shall not relieve the indemnifying party from any liability which it may have on account of the indemnity agreement contained in Section 4.5(a) to the extent that the failure to receive such notice within a reasonable period of time shall not have caused harm, loss or damage to the indemnifying party, provided that, conversely, if such failure to receive notice shall have caused any harm, loss or damage to the indemnifying party, such failure shall constitute a defense to any liability which such indemnifying party may have on account of such agreement to the extent of the harm, loss or damage so caused. In case any such action shall be brought against any indemnified party, its officers, directors and partners, or any such controlling person, and such indemnified party shall notify the indemnifying party of the commencement thereof, -7- /Page the indemnifying party shall be entitled to participate in (and, to the extent that the indemnifying party shall wish, to direct) the defense thereof at the indemnifying party's own expense, in which event the defense shall be conducted by recognized counsel chosen by the indemnifying party and approved by the indemnified party (whose approval shall not unreasonably be withheld) and the indemnified party may participate in such defense at its own expense (unless it is advised by counsel that actual or potential differing interests or defenses exist or may exist, in which case such expenses shall be paid by the indemnifying party, provided that the indemnifying party shall not be required to pay the expenses for more than one counsel for all such indemnified parties).
