The Sub-Advisor will indemnify the Advisor and its directors, members, partners, officers, employees and agents ("Advisor Parties") against and hold the Advisor Parties harmless from any and all losses, claims, damages, liabilities or expenses (including reasonable counsel fees and expenses) arising from any claim, demand, action or suit which results from the Sub-Advisor Parties' (as such term is defined immediately below) willful misfeasance, bad faith, gross negligence or reckless disregard of the Sub-Advisor's obligations and duties under this Agreement.
