respect thereof is to be made against the indemnifying party under subsection (a)&nbsp;or (b)&nbsp;above, notify the indemnifying party of the commencement thereof; but the failure to notify the indemnifying party shall not relieve it from any
liability that it may have under subsection (a)&nbsp;or (b)&nbsp;above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to

indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a)&nbsp;or (b)&nbsp;above (i)&nbsp;in such proportion as is appropriate
to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the offering of the Offered Securities or (ii)&nbsp;if the allocation provided by clause (i)&nbsp;above is not permitted by applicable
law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i)&nbsp;above but also the relative fault of the Company on the one hand and the Underwriters on the other in connection with the statements
or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be
in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters. The relative fault shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Underwriters and the parties&#146;
relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first
sentence of this subsection (d)&nbsp;shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d).
Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered
to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within
the meaning of Section&nbsp;11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters&#146; obligations in this subsection (d)&nbsp;to contribute are several in
proportion to their respective underwriting obligations and not joint. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section&nbsp;8(d) were determined by pro rata allocation (even if
the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this Section&nbsp;8(d). </FONT></P>
