ability of the indemnifying party to defend such action, shall relieve such indemnifying party, to the extent so prejudiced, of
any liability to the indemnified party under this <U>Section 2.6</U>, but the omission so to notify the indemnifying party shall

the relative fault of the indemnifying party on the one hand and of the indemnified party on the other in connection with the statements
or omissions that resulted in such loss, liability, claim, damage, or expense as well as any other relevant equitable considerations.
The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information
supplied by the indemnifying party or by the indemnified party and the parties&rsquo; relative intent, knowledge, access to information,
and opportunity to correct or prevent such statement or omission. In no event, however, shall (i) any amount due for contribution
hereunder be in excess of the amount that would otherwise be due under <U>Section 2.6(a)</U> or <U>Section 2.6(b)</U>, as applicable,
based on the limitations of such provisions and (ii) a Person guilty of fraudulent misrepresentation (within the meaning of the
