(a)        Seller’s Indemnity . Seller will indemnify, defend, and hold harmless Buyer against and in respect of claims, demands, losses, costs, expenses, obligations, liabilities, damages, recoveries, and deficiencies, including interest, penalties, and reasonable attorney fees that it may incur or suffer that arise or result from any: (i) Retained Liabilities; (ii) breach of, or failure by Seller to perform, any of its representations, warranties, covenants, or agreements in this Agreement or in any schedule, certificate, exhibit, or other instrument furnished or to be furnished by Seller under this Agreement; or (iii) conduct, events or assurances in connection with or related to the First Closing Assets which occurred prior to the First Closing Date or in connection with or related to the Second Closing Assets which occurred prior to the Second Closing Date.
