actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon any Violation or any of the transactions contemplated by this Agreement; provided that the Company shall not be liable under this provision
to the extent that such Claims resulted from the gross negligence or willful misconduct of the Indemnified Person. The Company shall reimburse each such Indemnified Person, promptly as such expenses are incurred and are due and payable, for any
documented reasonable legal fees or other documented and reasonable expenses incurred by them in connection with investigating or defending any such Claim. Notwithstanding anything to the contrary contained herein, the indemnification agreement
contained in this Section 8(a) shall not apply to amounts paid in settlement of any Claim if such settlement is effected without the prior written consent of the Company, which consent shall not be unreasonably withheld.



(2)Promptly after receipt by an Indemnified Person under this Section
8(a) of notice of the commencement of any action (including any governmental action), such Indemnified Person shall, if a Claim in respect thereof is to be made against the Company under this Section 8(a), deliver to the Company a notice of the
commencement thereof and the Company shall have the right to participate in, and, to the extent the Company so desires, to assume control of the defense thereof with counsel reasonably satisfactory to the Indemnified Person; provided,
however, that an Indemnified Person shall have the right to retain its own counsel with the fees and expenses to be paid by the Company, if, in the reasonable opinion of counsel retained by the Company, the representation by such counsel of the



---

Indemnified Person and the Company would be inappropriate due to actual or potential differing interests between such Indemnified Person and any other party
represented by such counsel in such proceeding; provided further, however, that the Company shall not be responsible for the fees and expenses of more than one separate counsel for all Indemnified Persons hereunder and one separate counsel in
each jurisdiction in which a Claim is pending or threatened. The failure to deliver notice to the Company within a reasonable time of the commencement of any such action shall not relieve the Company of any liability to the Indemnified Person under
this Section 8(a), except to the extent that the Company is prejudiced in its ability to defend such action. The indemnification required by this Section 8(a) shall be made by periodic payments of the amount thereof during the course of the
investigation or defense, as such expense, loss, damage or liability is incurred and is due and payable.



(b)Contribution. To the extent any indemnification by the Company as set forth in Section 8(a) above is applicable by its terms but is
prohibited or limited by law, the Company agrees to make the maximum contribution with respect to any amounts for which it would otherwise be liable under Section 8(a) to the fullest extent permitted by law. In determining the amount of contribution
to which the respective parties are entitled, there shall be considered the relative fault of each party, the parties relative knowledge of and access to information concerning the matter with respect to which the Claim was asserted, the
opportunity to correct and prevent any statement or omission and any other equitable considerations appropriate under the circumstances; provided, however, that (a) no contribution shall be made under circumstances where the maker would not
have been liable for indemnification under the fault standards set forth in Section 8(a) and (b) no Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any other
Person who was not guilty of such fraudulent misrepresentation.
