performance of its duties, or by reason of its reckless disregard of its obligations or duties under this Agreement.

Notwithstanding Section 13 of this Agreement, the Sub-Adviser agrees to indemnify and hold harmless the Adviser, any affiliated person of the Adviser, and any Controlling Person of the Adviser (the Adviser and all of such persons being referred to as “Adviser Indemnified Persons”) against any and all losses, claims, damages, liabilities, or litigation (including reasonable legal and other expenses) to which an Adviser Indemnified Person may become subject under the 1933 Act, 1940 Act, the Advisers Act, under any other statute, at common law or otherwise, arising out of the Sub-Adviser’s responsibilities as Sub-Adviser of the Portfolio which (i) may be based upon the Sub-Adviser’s gross negligence, willful misfeasance, or bad faith in the performance of its duties, or by reason of the Sub-Adviser’s reckless disregard of its obligations or duties under this Agreement, or (ii) may be based upon any untrue statement or alleged untrue statement of a material fact contained in the Fund’s Registration Statement, prospectus or statement of additional information, or any amendment or supplement thereto, or the omission or alleged omission to state therein a material fact known or which should have been known to the Sub-Adviser and was required to be stated therein or necessary to make the statements therein not misleading, unless such statement or omission was made in reliance upon information furnished by an Adviser Indemnified Person to the Adviser or the Trust or to any affiliated person of the Adviser; provided however, that in no case shall the indemnity in favor of the Adviser Indemnified Person be deemed to protect such person against any liability to which such person would otherwise be subject by reason of willful misfeasance, bad faith, or gross negligence in the performance of its duties, or by reason of its reckless disregard of its obligations or duties under this Agreement.

The Adviser shall not be liable under Paragraph (a) of this Section 14 with respect to any claim made against a Sub-Adviser Indemnified Person unless such Sub-Adviser Indemnified Person shall have notified the Adviser in writing within a reasonable time after the summons or other first legal process giving information of the nature of the claim shall have been served upon such Sub-Adviser Indemnified Person (or after such Sub-Adviser Indemnified Person shall have received notice of such service on any designated agent), but failure to notify the Adviser of any such claim shall not relieve the Adviser from any liability which it may have to the Sub-Adviser Indemnified Person against whom such action is brought except to the extent the Adviser is prejudiced by the failure or delay in giving such notice. In case any such action is brought against the Sub-Adviser Indemnified Person, the Adviser will be entitled to participate, at its own expense, in the defense thereof or, after notice to the Sub-Adviser Indemnified Person, to assume the defense thereof, with counsel reasonably satisfactory to the Sub-Adviser Indemnified Person. If the Adviser assumes the defense of any such action and the selection of counsel by the Adviser to represent the Adviser and the Sub-Adviser Indemnified Person would result in a conflict of interests and therefore, would not, in the reasonable judgment of the Sub-Adviser Indemnified Person, adequately represent the interests of the Sub-Adviser Indemnified Person, the Adviser will, at its own expense, assume the defense with counsel to the Adviser and, also at its own expense, with separate counsel to the Sub-Adviser Indemnified Person, which counsel shall be reasonably satisfactory to the Adviser and to the Sub-Adviser Indemnified Person. The Adviser shall not have the right to compromise on or settle the litigation without the prior written consent of the Sub-Adviser Indemnified Person if the compromise or settlement results, or may result in a finding of wrongdoing on the part of the Sub-Adviser Indemnified Person.

The Sub-Adviser shall not be liable under Paragraph (b) of this Section 14 with respect to any claim made against an Adviser Indemnified Person unless such Adviser Indemnified Person shall have notified the Sub-Adviser in writing within a reasonable time after the summons or other first legal process giving information of the nature of the claim shall have been served upon such Adviser Indemnified Person (or after such Adviser Indemnified Person shall have received notice of such service on any designated agent), but failure to notify the Sub-Adviser of any such claim shall not relieve the

Sub-Adviser from any liability which it may have to the Adviser Indemnified Person against whom such action is brought except to the extent the Sub-Adviser is prejudiced by the failure or delay in giving such notice. In case any such action is brought against the Adviser Indemnified Person, the Sub-Adviser will be entitled to participate, at its own expense, in the defense thereof or, after notice to the Adviser Indemnified Person, to assume the defense thereof, with counsel reasonably satisfactory to the Adviser Indemnified Person. If the Sub-Adviser assumes the defense of any such action and the selection of counsel by the Sub-Adviser to represent both the Sub-Adviser and the Adviser Indemnified Person would result in a conflict of interests and therefore, would not, in the reasonable judgment of the Adviser Indemnified Person, adequately represent the interests of the Adviser Indemnified Person, the Sub-Adviser will, at its own expense, assume the defense with counsel to the Sub-Adviser and, also at its own expense, with separate counsel to the Adviser Indemnified Person, which counsel shall be reasonably satisfactory to the Sub-Adviser and to the Adviser Indemnified Person. The Sub-Adviser shall not have the right to compromise on or settle the litigation without the prior written consent of the Adviser Indemnified Person if the compromise or settlement results, or may result in a finding of wrongdoing on the part of the Adviser Indemnified Person.
