b. The Placement Agent agrees to indemnify and hold harmless the Indemnitor against any and all loss, liability, claim, damage and expense whatsoever directly arising out of the exercise by any person of any right under the 1933 Act, the 1940 Act, or the Securities Exchange Act of 1934, or the securities or “blue sky” laws of any state on account of any violations by the Placement Agent of its representations and warranties set forth herein.

c. In no case shall any indemnifying party be liable under this Section 7 with respect to any claim made against an indemnified party unless such indemnifying party shall be notified in writing of the nature of the claim within a reasonable time after the assertion thereof, but failure so to notify such indemnifying party shall not relieve them from any liability which they many have otherwise than pursuant to this Section 7. An indemnifying party shall be entitled to participate at its own expense in the defense or, if it so elects within a reasonable time after receipt of such notice, to assume the defense, which defense shall be conducted by counsel chosen by it and satisfactory to the indemnified party, defendant or defendants in any suit so brought, unless such indemnified party reasonably objects to such assumption on the ground that there may be legal defenses available to such indemnified party different from or in addition to those available to such indemnifying party. In the event that the indemnifying party elects to assume the defense of any such suit and retain such counsel, the indemnified party, defendant of defendants in the suit shall bear the fees and expenses of any additional counsel thereafter retained by such indemnified party. In the event that the parties to any such action (including impleaded parties) include any of the Indemnitor and the Placement Agent, and the Placement Agent has been advised by counsel chosen by it and reasonable satisfactory to the Placement Agent that there may be one or more legal defenses available to the Placement Agent which are different from or additional to those available to the Indemnitor, the Indemnitor shall not have the right to assume the defense of such action on the Placement Agent’s behalf and will reimburse the Placement Agent as aforesaid for the reasonable fees and expenses or any counsel retained by it, it being understood that the Indemnitors shall not, in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstance, be liable for the reasonable fees and expenses of more than one separate firm of attorneys for the Placement Agent, which firm shall be designated in writing by the Placement Agent. The Indemnitor agrees to notify the Placement Agent within a reasonable time of the assertion of any claim in connection with the sale of the Shares against it or any person who controls the Trust.
